Translated fromChinese技术领域technical field
本发明涉及一种水流振动发电机，属于振动发电技术领域。 The invention relates to a water flow vibration generator, which belongs to the technical field of vibration power generation. the
背景技术Background technique
在现有的水力发电技术中，需要建立水库并使用带有水轮机的发电机。在现有的潮汐发电技术中，潮汐水坝(Tidal Barrage)技术需建立水库并使用带有水轮机的发电机；而潮汐流(Tidal streams)技术则使用水下的带有水轮机的发电机。在波浪发电技术中，需要建立蓄水池(TAPCHAN梯度渠道波动能力转换法)或密闭的腔体(OWC震荡空气柱法)并使用带有水轮机或汽轮机的发电机。由于需要建立蓄水单元和使用旋转部件，这些技术不适用于获取江河、沟渠和浅海中水流的能量。另外，蓄水单元的建立和旋转部件的使用会对环境和水生生物带来负面影响。为了能有效地利用江河、沟渠和浅海中水流及其波动的能量来发电，并减少发电机系统对景观和水生生物的不良影响以及其维护费用，需要提出和研究新颖的发电方法和发电机结构【参考文献1：Godfrey Boyle，Renewable Energy---Power for a sustainable future，OxfordUniversity Press，UK，2004.】。 In existing hydroelectric power generation technology, it is necessary to build a reservoir and use a generator with a water turbine. Among the existing tidal power generation technologies, the tidal dam (Tidal Barrage) technology needs to build a reservoir and use a generator with a water turbine; while the tidal stream (Tidal streams) technology uses an underwater generator with a water turbine. In wave power generation technology, it is necessary to build a reservoir (TAPCHAN gradient channel wave capacity conversion method) or a closed cavity (OWC oscillating air column method) and use a generator with a water turbine or a steam turbine. Due to the need to build water storage units and use rotating parts, these technologies are not suitable for harvesting energy from currents in rivers, ditches and shallow seas. In addition, the construction of the water storage unit and the use of rotating parts can have a negative impact on the environment and aquatic life. In order to effectively use the energy of rivers, ditches and shallow sea water flow and its fluctuations to generate electricity, and reduce the adverse impact of the generator system on the landscape and aquatic organisms and its maintenance costs, it is necessary to propose and study novel power generation methods and generator structures.

发明内容Contents of the invention
本发明目的是为了克服现有的发电方法不能充分利用江河、沟渠和浅海中水流能量的不足，提供一种水流振动发电机。 The purpose of the present invention is to provide a water flow vibration generator to overcome the deficiency that the current power generation method cannot fully utilize the water flow energy in rivers, ditches and shallow seas. the
一种水流振动发电机，其特征在于：包括箱体、置于箱体内的密封线圈盒和密封永久磁铁盒，密封线圈盒内安装有线圈组、密封永久磁铁盒内安装有永久磁铁组，密封线圈盒和密封永久磁铁盒其中一个盒体安装于箱体底部呈固定状态作为定子、另一个盒体通过并联弹簧与箱体顶部相连呈悬吊状态作为振动子；上述振动子与箱体四周、与定子之间留有活动间隙；上述线圈组与永久磁铁组正对，即永久磁铁组中每个永久磁铁与线圈组中相应的线圈相对，穿过线圈的磁力线数目为最大；上述箱体还设有进水口和出水口，进水口和出水口分别位于箱体的两个相对侧面上部。A water flow vibration generator, characterized in that it includes a box body, a sealed coil box and a sealed permanent magnet box placed in the box body, a coil group is installed in the sealed coil box, a permanent magnet group is installed in the sealed permanent magnet box, and the sealed permanent magnet box is sealed. One of the coil box and the sealed permanent magnet box is installed on the bottom of the box in a fixed state as a stator, and the other box is connected to the top of the box through parallel springs and is in a suspended state as a vibrator; There is an active gap between the stator and the stator; the above-mentioned coil group is directly opposite to the permanent magnet group, that is, each permanent magnet in the permanent magnet group is opposite to the corresponding coil in the coil group, and the number of magnetic force lines passing through the coil is the largest; the above-mentioned box is also A water inlet and a water outlet are provided, and the water inlet and the water outlet are respectively located at the upper parts of two opposite sides of the box body.
上述密封线圈盒位于背离密封永久磁铁盒一侧还可以设有增加通过线圈磁通量的软铁片。 The above-mentioned sealed coil box can also be provided with a soft iron sheet to increase the magnetic flux passing through the coil on the side away from the sealed permanent magnet box. the
上述进进水口或和出水口为喇叭形结构，可以增加发电机中水的流速及其波动速度，进而增加作用在发电机振子(线圈盒或永久磁铁盒)的励振力，增加发电机的输出电压，并使得发电机在水流方向反转时也能使用。 The above-mentioned water inlet or water outlet is a trumpet-shaped structure, which can increase the flow velocity and fluctuation velocity of the water in the generator, thereby increasing the excitation force acting on the generator vibrator (coil box or permanent magnet box), and increasing the output of the generator voltage and allows the generator to be used even when the direction of water flow is reversed. the
上述进水口或和出水口中设置有过滤网，可以防止泥砂、水声生物和其它固体物质的进入。 The above-mentioned water inlet or the water outlet is provided with a filter screen, which can prevent the entry of mud, sand, hydroacoustic organisms and other solid substances. the
上述箱体的底部设有细泥砂排出孔，可以方便排除泥沙。 The bottom of the above box body is provided with discharge holes for fine sand, which can facilitate the removal of sand. the
上述振动发电机的发电方法的特征是：当水流经振动子上方的腔体时，由于腔体中的水流速度要大于线圈盒和永久磁铁盒之间缝隙中的水流速度，根据伯努力定律(BERNOULLI’S LAW)，缝隙中的静压力要大于腔体中的静压力，因而振子受到一向上的力Fm。由于腔体中水流速度随时间的波动，作用在振子上的力Fm也随时间波动，这会引起弹簧系统的振动。弹簧系统的振动会引起永久磁铁的磁场和相应线圈之间的相对运动，进一步导致线圈中感应电势的产生。 The feature of the power generation method of the above-mentioned vibration generator is: when water flows through the cavity above the vibrator, because the water flow velocity in the cavity is greater than the water flow velocity in the gap between the coil box and the permanent magnet box, according to Bernoulli's law ( BERNOULLI'S LAW), the static pressure in the gap is greater than the static pressure in the cavity, so the vibrator is subjected to an upward force Fm . Due to the fluctuation of water velocity in the cavity with time, the forceFm acting on the vibrator also fluctuates with time, which will cause the vibration of the spring system. The vibration of the spring system will cause the relative motion between the magnetic field of the permanent magnet and the corresponding coil, which further leads to the generation of induced electric potential in the coil.
本发明专利的有益效果是：发电机无旋转部件，并且可以被做成扁平状。因而它可以利用各种浅水中的水流进行发电，能充分利用江河、沟渠和浅海中的水流及其波动能量；通过将其置于水底，能消除发电机对航道、海滨旅游地的景观等的不良环境影响；本发明中发电机的使用能减少水下发电装置的维护费用。 The beneficial effect of the patent of the present invention is that the generator has no rotating parts and can be made into a flat shape. Therefore, it can use the water flow in various shallow waters to generate electricity, and can make full use of the water flow and its wave energy in rivers, ditches and shallow seas; Adverse environmental impact; the use of the generator in the present invention can reduce the maintenance cost of the underwater power generation device. the
