Description

Translated fromJapanese

本発明は、電動農業機械への電力供給方法に関する。The present invention relates to a method for supplying power to an electric agricultural machine.

内燃機関の代わりに電動機を搭載した電動農業機械が実用化されている。電動機を駆動させるための電力は、蓄電池に蓄えられ、蓄電池に蓄えられた電力量の範囲で、電動農業機械は、農作業が可能となっている。Electric agricultural machinery equipped with an electric motor instead of an internal combustion engine has been put to practical use. The electricity to drive the electric motor is stored in a storage battery, and the electric agricultural machinery can perform farm work within the range of the amount of electricity stored in the storage battery.

電動トラクタなどの電動農業機械は、実用化されているものの、その使用は限定的なものである。具体的には、蓄電池容量を大きくすれば、連続作業時間は長くなるものの、車体重量が重くなり、耕起等における作業性は低下してしまう。逆に、蓄電池容量を小さくすれば、耕起等における作業性は向上するものの、連続作業時間が短くなってしまう。いずれにせよ、内燃機関に比べ蓄電池が重いため、作業効率が悪く、現状の電動農業機械では、短時間かつ軽負荷な耕起等に限定される。Although electric agricultural machinery such as electric tractors has been put to practical use, its use is limited. Specifically, if the storage battery capacity is increased, the continuous working time becomes longer, but the vehicle weight becomes heavier, and workability in plowing, etc. decreases. Conversely, if the storage battery capacity is decreased, workability in plowing, etc. improves, but the continuous working time becomes shorter. In any case, since the storage battery is heavier than the internal combustion engine, the work efficiency is poor, and the current electric agricultural machinery is limited to short-time, light-load plowing, etc.

圃場に充電設備を整備し、電動農業機械に逐次充電する方法も考えられるが、充電に時間がかかり、時間当たりの作業効率が低下してしまう。高い電力で充電する急速充電もあるが、それを圃場に整備すれば、規模の大きい受変電設備が必要となり、大きなコスト増加となってしまう。One possible method would be to set up charging equipment in the field and gradually charge the electric agricultural machinery, but this would take time to charge, reducing work efficiency per hour.There is also a fast charging system that charges at high power, but setting this up in the field would require large-scale substation equipment, which would significantly increase costs.

蓄電池を交換する方法も考えられるが、圃場まで交換用の蓄電池を運ぶ必要が生じてしまう。また、交換も蓄電池が重く、交換のための機械が必要か、人力で交換できるように小分けにすれば、蓄電池の個数が増え、交換に時間を要してしまう。Although it is possible to replace the storage batteries, this would require transporting the replacement batteries to the field. In addition, the batteries are heavy, so a machine would be required for replacement, or if they were divided into small pieces so that they could be replaced manually, the number of batteries would increase, which would take time to replace.

本発明のシステムは、図1、図2、図3に示すように、圃場1に構造物2を設置し、農業機械3が構造物2の下を通過する際に、農業機械3に搭載する集電装置3aが構造物2に敷設した金属棒2fに接触し、農業機械3がその接点から電力を受電するものである。農業機械3が構造物2の下にあるときは、受電した電力がモータ駆動と蓄電池充電に使われ、農業機械3が構造物2の下にないときは、蓄電池に充電された電力を用いて、モータ駆動をさせ、農作業を長時間連続的に実施することができる。金属棒2fには、電気設備群4から電力が供給され、電気設備群4は、電力系統に接続し、電力を受電する。In the system of the present invention, as shown in Figures 1, 2 and 3, astructure 2 is installed in afarm field 1, and when anagricultural machine 3 passes under thestructure 2, a current collector 3a mounted on theagricultural machine 3 comes into contact with a metal rod 2f laid on thestructure 2, and theagricultural machine 3 receives electric power from the contact point. When theagricultural machine 3 is under thestructure 2, the received electric power is used to drive the motor and charge the storage battery, and when theagricultural machine 3 is not under thestructure 2, the motor is driven using the electric power charged in the storage battery, making it possible to carry out agricultural work continuously for long periods of time. Electric power is supplied to the metal rod 2f from a group ofelectrical equipment 4, and the group ofelectrical equipment 4 is connected to a power grid and receives electric power.

本発明の一実施形態として、図3に圃場1の一部に構造物2を配置した平面図を示す。圃場1の全部ではなく、一部に構造物2を設置することで、構造物2の規模を小さくし、経済性を向上させることができる。好ましくは、構造物2を圃場1の中央部に配置することで、構造物のない部分の農作業時間を短くすることができる。構造物の大きさは、圃場1の形状、農業機械3に搭載される蓄電池の容量、農作業の負荷によって、計算される。As one embodiment of the present invention, Fig. 3 shows a plan view in which astructure 2 is arranged in a part of afield 1. By installing thestructure 2 in part of thefield 1 rather than thewhole field 1, the scale of thestructure 2 can be reduced, improving economy. Preferably, by arranging thestructure 2 in the center of thefield 1, the agricultural work time in parts where there is no structure can be shortened. The size of the structure is calculated based on the shape of thefield 1, the capacity of the storage battery mounted on theagricultural machine 3, and the load of the agricultural work.

構造物2の一実施形態として、図4と図5に示すように、圃場1にスクリュー杭構造とする基礎2aに、支柱2bが固定され、その上に横梁2cが固定され、その上に縦梁2dが固定される。支柱2bと横梁2c及び縦梁2dは、それぞれ斜材2eで固定される。横梁2cに碍子2fが設置され、そこに金属棒2gが転架される。As shown in Figures 4 and 5, one embodiment of thestructure 2 is a screw pile foundation 2a in thefield 1, with a support 2b fixed thereto, a cross beam 2c fixed thereon, and a vertical beam 2d fixed thereon. The support 2b, the cross beam 2c, and the vertical beam 2d are each fixed to a diagonal member 2e. An insulator 2f is installed on the cross beam 2c, and a metal rod 2g is placed on it.

農業機械3の一実施形態として、図6と図7に示すように、農業機械に集電装置3aを搭載する。集電装置3aには、伸縮可能及び前後にスイング可能なアーム3bが設置され、アーム3bの上部に設置される2つの金属体3cが、構造物2の金属棒2gと接触できるようになっている。移植機やコンバインなども同様に、集電装置3aを搭載することで、架線給電システムによって稼働させることができる。As one embodiment of theagricultural machine 3, as shown in Figures 6 and 7, a current collector 3a is mounted on the agricultural machine. An arm 3b that is extendable and swingable back and forth is installed on the current collector 3a, and two metal bodies 3c installed on the upper part of the arm 3b are capable of contacting a metal rod 2g of thestructure 2. Similarly, by mounting the current collector 3a, transplanters, combine harvesters, and the like can also be operated by the overhead power supply system.

農業機械3が構造物2の下に位置する場合には、農業機械3の集電装置3aの金属体3cと構造物2の金属棒2gが確実に接触できるよう、集電装置3aに左右可動装置3dとカメラ3eを設置して、カメラ3eによって得られた画像から位置関係を認識し、左右可動装置3dで位置を調整してもよい。もしくは、左右可動装置3dを設置せず、農業機械3自体を自動運転として、その操作によって、位置を調整してもよい。When theagricultural machine 3 is located under thestructure 2, a left-right movable device 3d and a camera 3e may be installed on the current collector 3a so that the metal body 3c of the current collector 3a of theagricultural machine 3 can be reliably in contact with the metal rod 2g of thestructure 2, and the positional relationship may be recognized from an image obtained by the camera 3e, and the position may be adjusted by the left-right movable device 3d. Alternatively, the left-right movable device 3d may not be installed, and theagricultural machine 3 itself may be operated automatically, and the position may be adjusted by operating it.

図8のように、左右可動装置3dの左右の可動範囲を広げることで、架線の本数を少なくすることができる。好ましくは、支柱2bの間に1組の架線でも、給電を可能にすることができる。As shown in Fig. 8, the number of overhead lines can be reduced by widening the left-right movable range of the left-right movable device 3d. Preferably, power can be supplied with even one set of overhead lines between the pillars 2b.

図9は、電気設備の一実施形態である。電力配電設備からの電線を電柱4aで受けて、電力ケーブル4bで送配電事業者の設置する電力量計4cに接続され、遮断器の入るプラボックス4dに接続され、直流ユニット4eに接続される。その先、電力ケーブルによって、金属棒2gにつながれ、直流電力が供給される。9 shows an embodiment of the electrical equipment. An electric wire from the power distribution equipment is received by a utility pole 4a, and is connected by a power cable 4b to a watt-hour meter 4c installed by the power transmission and distribution company, then to a plastic box 4d containing a circuit breaker, and then to a DC unit 4e. The power cable then connects the wire to a metal rod 2g, through which DC power is supplied.

図10は、本発明の電気回路の一実施形態である。電力系統の配電線から受電し、電力量計4cと遮断器4dを介して、直流ユニット4eにて、交流電力を直流電力に変換し、構造物2の金属体2gに直流電力を流す。農業機械3の内部では、金属体3cで受電した電力を、DCブレーカ4gを介して、モータを駆動させるため駆動用インバータ4hと蓄電池用のDC/DCコンバータ4jに並列で接続される。農業機械3が構造物2の下に位置する際は、架線から供給された直流電力の一部をモータ駆動用インバータ4hで交流電力に変換して、同期モータ4iを駆動させる。また、架線から供給された直流電力の一部をDC/DCコンバータ4jにて、蓄電池4kに充電できる電圧に変換して、蓄電池4kを充電する。一方、農業機械3が構造物2の下に位置しない際は、蓄電池4kからDC/DCコンバータ4jを介して直流電力を、モータ駆動用インバータ4hに送り、モータ駆動用インバータ4hが交流電力に変換して、同期モータ4iが駆動する。10 is an embodiment of the electric circuit of the present invention. Power is received from the distribution line of the power system, and AC power is converted to DC power by the DC unit 4e via the watt-hour meter 4c and the circuit breaker 4d, and the DC power is passed through the metal body 2g of thestructure 2. Inside theagricultural machine 3, the power received by the metal body 3c is connected in parallel to the drive inverter 4h and the DC/DC converter 4j for the storage battery via the DC breaker 4g to drive the motor. When theagricultural machine 3 is located under thestructure 2, a part of the DC power supplied from the overhead line is converted to AC power by the motor drive inverter 4h to drive the synchronous motor 4i. In addition, a part of the DC power supplied from the overhead line is converted to a voltage that can be charged to thestorage battery 4k by the DC/DC converter 4j, and thestorage battery 4k is charged. On the other hand, when theagricultural machine 3 is not located under thestructure 2, DC power is sent from thestorage battery 4k via the DC/DC converter 4j to the motor drive inverter 4h, which converts it into AC power to drive the synchronous motor 4i.

構造物2の電気設備及び農業機械3は、通信装置4m・4nで連携され、直流ユニットの制御コンピュータ4oがAC/DCコンバータ4pを制御し、農業機械3の制御コンピュータ4lがモータ駆動インバータ4h及びDC/DCコンバータ4jを制御する。金属棒2gと金属体3cが接触していないときには、AC/DCコンバータ4pと農業機械3のDCブレーカ4cを開くことで、感電等の事故を軽減できる。The electrical equipment of thestructure 2 and theagricultural machinery 3 are linked by communication devices 4m and 4n, with the DC unit's control computer 4o controlling the AC/DC converter 4p, and theagricultural machinery 3's control computer 4l controlling the motor drive inverter 4h and the DC/DC converter 4j. When the metal rod 2g and the metal body 3c are not in contact with each other, the AC/DC converter 4p and the DC breaker 4c of theagricultural machinery 3 can be opened to reduce accidents such as electric shock.

構造物2に太陽光発電設備を設置してもよい。この一実施形態として、図11を示す。図12は、太陽光発電設備5を設置した場合の電気回路の一実施形態である。A photovoltaic power generation facility may be installed in thestructure 2. One embodiment of this is shown in Fig. 11. Fig. 12 shows one embodiment of an electric circuit when a photovoltaicpower generation facility 5 is installed.

図13のように、農業機械3の集電装置3aを着脱式にして、集電装置3aの代わりに内燃機関発電装置6aや燃料電池発電装置6bを装着できるようにしても良い。この場合、構造物2のない圃場においても、農業機械3は、内燃機関発電装置6aや燃料電池発電装置6bを装着することで、農作業ができるようになる。13, the current collector 3a of theagricultural machine 3 may be made detachable so that an internal combustion enginepower generating device 6a or a fuel cellpower generating device 6b can be attached instead of the current collector 3a. In this case, even in a field where there is nostructure 2, theagricultural machine 3 can perform farm work by attaching the internal combustion enginepower generating device 6a or the fuel cellpower generating device 6b.

図14のように、内燃機関発電装置6aや燃料電池発電装置6bを、電力系統に接続された系統接続機6cに装着することで、電量系統に電力を供給できるようにしても良い。図15は、太陽光発電設備5を設置した場合の電気回路の一実施形態である。As shown in Fig. 14, an internal combustion enginepower generation device 6a or a fuel cellpower generation device 6b may be attached to asystem connector 6c connected to a power system so that it can supply power to the energy system. Fig. 15 shows one embodiment of an electric circuit when a solarpower generation facility 5 is installed.

圃場の中で電動農業機械に給電することで、蓄電池の規模を小さく抑え、耕起等の作業性を確保したまま、連続作業時間を伸ばすことができる。また、農協機械3の蓄電池4iに充電することで、構造物2を圃場1の全体ではなく、一部に限って設置することが可能となり、構造物の設置に係るコストを抑えることができる。By supplying power to electric agricultural machinery in the field, the size of the storage battery can be kept small, and continuous working time can be extended while ensuring workability in plowing, etc. Also, by charging the storage battery 4i of theagricultural cooperative machinery 3, it becomes possible to install thestructure 2 only in a part of thefield 1, rather than theentire field 1, and the cost of installing the structure can be reduced.

架線給電で稼働する機械は、電車、路面電車、トロリーバス等で実用化されてきているが、いずれも走行ルートが決められており、架線による給電が容易である。本発明では、走行ルートの決まっていない圃場において、農作業の途中で農業機械に給電を可能にするものである。Machines that run on overhead power lines have been put to practical use in trains, trams, trolleybuses, etc., but the running routes of all of these are fixed, making it easy to supply power via overhead lines. The present invention makes it possible to supply power to agricultural machines in the middle of agricultural work in fields where the running route is not fixed.

左右可動装置3dによって、金属体3cの位置を動かすことで、農業機械3は、農作業の必要があるルートを走行することが可能である。好ましくは、左右可動装置3dの可動範囲を大きくすることで、架線の本数を削減でき、コスト削減することができる。By moving the position of the metal body 3c by the left-right movable device 3d, theagricultural machine 3 can travel along a route where farm work is required. Preferably, by increasing the movable range of the left-right movable device 3d, the number of overhead wires can be reduced, leading to cost reduction.

構造物2に太陽光発電設備を設置することで、発電による収益が追加され、構造物の投資回収が早まる。また、日照のある間に、農業機械3での農作業を行うことで、電力系統からの購入電力量を抑制し、農業の事業性も向上する。By installing a solar power generation system on thestructure 2, revenue from power generation will be added, and the investment for the structure will be recovered sooner. In addition, by performing agricultural work with theagricultural machinery 3 during the sunshine, the amount of electricity purchased from the power grid will be reduced, improving the business viability of agriculture.

集電装置3aを着脱式にすることで、構造物3のない圃場においては、ガソリン、軽油、植物油などの液体燃料を燃料とする内燃機関発電装置6aを装着し、農業機械3を稼働させることができる。また、将来、水素がエネルギー媒体として流通するようになれば、水素を燃料とする燃料電池発電装置6bにしてもよい。By making the current collector 3a detachable, in fields withoutstructures 3, it is possible to install an internal combustion enginepower generation device 6a that uses liquid fuel such as gasoline, diesel, or vegetable oil as fuel to operate theagricultural machine 3. Furthermore, if hydrogen becomes available as an energy medium in the future, a fuel cellpower generation device 6b that uses hydrogen as fuel may be used.

内燃機関発電装置6aや燃料電池発電装置6bを系統接続装置に装着することで、電力系統の需給ひっ迫時に、内燃機関や燃料電池を使って発電した電力を電力系統に供給しても良い。その売電によって副収入が得られ、農業の経営状況が向上する可能性がある。By mounting the internal combustion enginepower generation device 6a or the fuel cellpower generation device 6b to the grid connection device, electricity generated using the internal combustion engine or the fuel cell can be supplied to the grid when the supply and demand of the grid is tight. Selling the electricity can provide additional income, which may improve the management of agricultural businesses.

以下、本発明の一実施形態について説明する。本実施形態では、図3のように、圃場1の長辺方向に対して中央部に、構造物2を設置する。農業機械2は、圃場1の長辺方向に走行して、耕起等の農作業を行う。構造物2の下を通過する際に、農業機械3が集電装置3aを動かし、2つの金属体3aが2構造物の2つの金属体2aに接して、電力を受電する。An embodiment of the present invention will be described below. In this embodiment, as shown in Fig. 3, astructure 2 is installed in the center of a long side of afield 1. Theagricultural machine 2 travels in the long side of thefield 1 and performs agricultural work such as plowing. When passing under thestructure 2, theagricultural machine 3 moves the current collector 3a, and the two metal bodies 3a come into contact with the two metal bodies 2a of thestructure 2 to receive electric power.

農業機械3が保管される倉庫等と圃場の間の移動が必要であるが、本発明の農業機械3は、蓄電池を搭載しており、そこに充電された電力によって、架線のない一般道や農道での移動が可能である。圃場での農作業と違い、一般道や農道の移動は、負荷が小さいため、架線給電がなくても、圃場よりも長い距離の走行が可能である。Theagricultural machine 3 needs to be moved between a warehouse or the like where it is stored and the field, but theagricultural machine 3 of the present invention is equipped with a storage battery, and the electric power stored in the battery enables it to be moved on general roads and farm roads without overhead power lines. Unlike agricultural work in a field, movement on general roads and farm roads imposes a small load, so it is possible to travel longer distances than in a field, even without overhead power supply.

農業機械の自動運転技術が進んでおり、一部実用化されている。本発明においても、自動運転との組み合わせが好ましい。特に、農業機械を操作する人にとって、構造体2の支柱2bが邪魔なものであるが、自動運転となれば、それは無関係となる。さらには、自動運転の農業機械に搭載されたカメラやレーザースキャナ等によって、支柱の位置を正確に把握することで、より正確な操作も可能となる。The technology for automatic operation of agricultural machinery has been advanced and has been partially put to practical use. In the present invention, it is preferable to combine it with automatic operation. In particular, the support pillars 2b of thestructure 2 are an obstacle for the person operating the agricultural machinery, but if the agricultural machinery is automatically operated, this becomes irrelevant. Furthermore, by accurately grasping the position of the support pillars using a camera or laser scanner mounted on the automatically operated agricultural machinery, more accurate operation is possible.

農業機械3の左右可動装置3dの可動範囲を大きくすることで、架線の本数を少なくすることができる。左右可動装置3dの可動範囲が小さければ、片道で耕起等の農作業ができる幅に対して、1組の架線が必要となるが、左右可動装置3dの可動範囲が農作業できる幅を超えれば、農作業できる幅2つに対して、1組の架線で受電できるようになる。The number of overhead lines can be reduced by increasing the movable range of the left and right movable devices 3d of theagricultural machine 3. If the movable range of the left and right movable devices 3d is small, one set of overhead lines is required for the width where agricultural work such as plowing can be done in one direction, but if the movable range of the left and right movable devices 3d exceeds the width where agricultural work can be done, it becomes possible to receive power with one set of overhead lines for two widths where agricultural work can be done.

図11と図12のように、構造物2に太陽光発電システム5を搭載することができる。太陽光発電5を搭載することで、農業機械3への電力供給以外に発電事業が可能となり、構造物2や電力系統からの受電設備も有効活用でき、システム全体での経済性が高められる。11 and 12 , a solarpower generation system 5 can be installed on thestructure 2. By installing the solarpower generation system 5, it becomes possible to generate electricity in addition to supplying power to theagricultural machinery 3, and thestructure 2 and power receiving equipment from the power grid can be effectively utilized, improving the economic efficiency of the entire system.

図13のように、集電装置3aを農業機械3と着脱可能にする方式もある。農業機械3に装着できる電源装置しては、内燃機関発電装置6aや燃料電池発電装置6bなど多様な電源がある。こうした着脱可能にすることで、例えば、架線給電システムのない圃場では、内燃機関装置6aを農業機械3に装着し、圃場の耕起等の作業が可能となる。As shown in Fig. 13, there is also a system in which the current collector 3a is detachable from theagricultural machine 3. There are various power sources such as an internal combustionengine power generator 6a and a fuelcell power generator 6b as power supply devices that can be attached to theagricultural machine 3. By making it detachable in this way, for example, in a field without an overhead power supply system, the internalcombustion engine device 6a can be attached to theagricultural machine 3 and work such as plowing the field can be performed.

図14と図15のように、内燃機関発電装置6a及び燃料電池発電装置6bを、電力系統に接続できる系統接続装置に装着させて、発電機として電力系統に給電することも良い。As shown in Figs. 14 and 15, the internal combustion enginepower generating device 6a and the fuel cellpower generating device 6b may be attached to a system connection device that can be connected to a power system, and used as a generator to supply power to the power system.
