Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, completeSite preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based onEmbodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every otherEmbodiment shall fall within the protection scope of the present invention.
Core of the invention is to provide a kind of laser radar explosion-protection equipment, can be improved the safety that laser radar uses.
In a kind of specific embodiment of laser radar explosion-protection equipment provided by the present invention, Fig. 1 to Fig. 3 is please referred to, including withIn being located on the outside of laser radar with explosion-proof cloche 1, cloche 1 is the quartz glass cover for capableing of light transmission.Wherein, the glassCover 1 can be specifically located on the outside of 3D laser radar.Wherein, the higher the better for the laser transmissivity of cloche.
In the present embodiment, in explosive gas atmosphere, using can explosion-proof cloche cover laser radar, with flame proofMode to laser radar carry out it is explosion-proof, without changing the structure of laser radar itself, easy to use, explosion-proof effect is preferable, canSo that laser radar security application in the present context.Simultaneously as cloche is light transmission, the light of laser radar can be penetratedOut, it can guarantee the normal use of laser radar.In addition, because needing laser beam injection/receiving particularity when laser radar work,Flame proof must use transparent material, and need to take into account light and small, high mechanical strength requirement is lost thoroughly.Quartz is set by cloche 1Cloche, quartz glass, that is, high-purity quartz material manufacture glass, belongs to optical glass scope.Quartz glass has extremely low heatThe coefficient of expansion, higher heat resistance, fabulous chemical stability, excellent electrical insulating property, low and stable ultrasonic delay performance,Optimal ultraviolet spectra performance and saturating visible light and near infrared spectrum performance, and have the mechanicalness higher than simple glassCan, keep the mechanical strength of explosion-protection equipment higher.
On the basis of the above embodiments, cloche 1 can be the four prisms cylinder of two axial end portion opening settings, that is,The cloche 1 is in the cyclic structure of quadrangle, and the both ends open of cloche 1 is arranged, and can facilitate the assembling with laser radar,It can select light transmission or lighttight component that the opening of cloche 1 is set according to actual needs simultaneously, to improve when anti-The applicability of quick-fried device.
On the basis of the above embodiments, the both ends of cloche 1 can be sealed by metal plate 3 respectively, pass through clocheSealing space is formed with metal plate.Optionally, the volume of the sealing space can be 2L.Using metal plate 3, can guarantee explosion-proofThe intensity of device.Certainly, the axial end portion of cloche 1 can also select plastic plate or other plate member seals.
Based on any of the above embodiments, cloche 1 can be spliced by four glass plates, and glass plate is taken to spellCloche 1 is made in the mode connect, easy to process, advantageously ensures that machining accuracy, consequently facilitating realizing mass production.Adjacent twoIt is connected between a glass plate by metal column 4, and metal column 4 is set on the rib of four prisms cylinder, advantageously ensures that the effective of light transmissionArea, meanwhile, quadrangular can guarantee the stability that cloche 1 is placed.Preferably, glass plate is slide plate.
Optionally, 4 diameter of metal column can be 10mm, glass plate and metal flanging >=5mm after glass plate splicing.
Further, quadrangular can be rectangle perpendicular to axial section, and according to calculating, effective form can reach 60%More than, it is ensured that the effective area of laser transmission.
Based on any of the above embodiments, the outside of each glass plate can be equipped with the frame 5 for reinforcement, frame 5It is corresponding with the edge of corresponding glass plate to be fixedly connected, that is, four glass plates connect one to one with four frames 5.Optionally,Frame 5 can be the biggish metal frame of intensity.Glass plate is reinforced fixing with frame 5, can be avoided glass plate deformation, furtherImprove the intensity of cloche 1.Optionally, frame 5 can be connect with cloche 1 with screw, in order to dismantle and repair.
Further, cricoid boss 6 can be set in an axial end portion of cloche 1, and the boss 6 is corresponding with frame 5It is fixedly connected, and boss 6 is radially projecting relative to frame 5.The setting of boss 6 is advantageously implemented the steady placement of cloche 1,Cloche 1 is avoided to topple over.
Based on any of the above embodiments, the thickness of cloche 1 can be 12mm-15mm, for example, 12mm, 13mm,14mm or 15mm, to guarantee the mechanical strength of cloche 1.Certainly, the thickness of cloche 1 can also be set as needed as otherNumerical value.
Based on any of the above embodiments, which can also include being arranged outside cloche 1The protective net 2 of side, protective net 2 include the dictyosome that setting is respectively corresponded with each glass plate, that is, four glass plates and four dictyosomes oneOne is correspondingly connected with.Optionally, dictyosome can be fixedly connected on frame 5, can specifically pass through the side of welding or screw connectionFormula.In the present embodiment, protective net 2 is added in the outside of cloche 1, the explosion-proof reliability of explosion-protection equipment can be reinforced, is improved anti-The intensity of quick-fried device.
More specifically, dictyosome can by with certain angle the first metal strip 21 and the second metal strip 22 be staggered shapeAt.In dictyosome, all first metal strips 21 are arranged in parallel, and all second metal strips 22 are arranged in parallel, and dictyosome is by two kinds of metalsItem is constituted, easy to process, and selects metal strip that can guarantee mechanical strength.Meanwhile first metal strip 21 and the second metal strip 22It is arranged both with respect to peripheral, oblique.Metal strip is obliquely installed with respect to the circumferential direction, can be blocked completely to avoid metal strip a certain wholeLaser beam circumferentially can guarantee the reliable use of laser radar.
Specifically shown in Fig. 1 for orientation, laser radar can be rotated around horizontal rotating shaft and pitching shaft, the horizontal rotating shaftIt is conllinear with the central axis of cloche 1.Under identical pitch angle laser radar around horizontal rotating shaft rotate one week, on one glass plate byThe laser beam being linked to be up to several laser points of lower formation, every laser beam are in substantially parallel relationship to circumferential direction.Due to metal strip withIt is circumferentially arranged in an oblique way, the laser beam formed under some pitch angle can be blocked completely to avoid metal strip.
Preferably, the tilt angle of the first metal strip 21 with respect to the circumferential direction can be 45 degree, the second metal strip 22 and firstMetal strip 21 perpendicular can be arranged.Certainly, the first metal strip 21 or the second metal strip 22 and circumferential angle can also be 30Degree, 40 degree or other degrees.
Optionally, in dictyosome, all first metal strips 21 can be with equidistantly distributed and all second metal strips 22 can be withEquidistantly distributed, to further decrease difficulty of processing.Optionally, distance values can be 15mm.
