And the drying mechanism 3 is connected to the upper part of the rack 1 through bolts. The wiping mechanism 3 is located right above the cleaning mechanism 2 and is used for wiping off pollutants on the surface of the camera passing through the cleaning mechanism from the periphery side.

The lifting frame 4 is connected to the upper end of the machine frame 1 through four upright posts by screw threads, and the lifting frame 4 is of a circular ring structure. The outer wall of the frame 1 is welded with a storage cylinder 5 and a recovery box 6. The storage cylinder 5 stores a cleaning liquid. The recovery tank 6 is used for recovering the cleaning liquid.

In the process, the camera is bound at the lower end of the lifting frame 4 and extends into the cleaning mechanism 2 from top to bottom along the longitudinal direction. The storage cylinder 5 conveys the cleaning liquid into the cleaning mechanism 2, and the cleaning mechanism 2 sprays the cleaning liquid to the outer surface of the cleaned camera from the peripheral side, so that the camera is cleaned primarily. Then, the camera is pulled upwards along the longitudinal direction, the camera moves upwards and enters the wiping mechanism 3, and the wiping mechanism 3 surrounds the camera from the peripheral side. The surface of the camera is cleaned of contaminants during contact between the wiping mechanism 3 and the camera. In the process, the cleaning mechanism 2 sprays cleaning liquid to the camera from the peripheral side, and the wiping mechanism 3 wipes the surface of the camera from the peripheral side, so that the pollutants on each part of the surface of the camera are thoroughly cleaned.

About wiper mechanism 2 sprays the washing liquid to the surface of camera to realize the preliminary washing of the pollutant on camera surface, the concrete process is as follows:

referring to fig. 2, the cleaning mechanism 2 includes a cylinder 21, and a diversion cavity 22 extending along a circumferential direction of the cylinder 21 is formed in a side wall of the cylinder 21. A micro water pump 23 is bolted to the outside of the cylinder 21. A plurality of cleaning members 27 are bolted to the inner wall of the cylinder 21, and the plurality of cleaning members 27 are spaced apart from each other in the circumferential direction of the inner wall of the cylinder 21. The micro water pump 23 conveys the cleaning liquid to the cleaning part 27 through the diversion cavity 22, and the cleaning liquid is sprayed on the outer surface of the camera by the cleaning part 27.

In this embodiment, since a plurality of cleaning members 27 are used and the plurality of cleaning members 27 are distributed at intervals along the circumferential direction of the inner cavity of the cylinder 21, when the camera is placed in the cylinder 21. Miniature pump 23 carries the washing liquid in the storage cylinder 5 to pass through in the water conservancy diversion chamber 22 carries the washing 27, and a plurality of washing 27 respectively spray the washing liquid to the surface of camera from the different positions and the angle around the camera on for each position in the surface of camera all can be covered by the washing liquid, avoids certain position on camera surface to lead to the pollutant of this department can not by effective clearance problem because not spraying the washing liquid, ensures that the pollutant on camera surface is cleared up comprehensively.

In this embodiment, the cleaning solution is sprayed onto the camera through the cleaning member 27, and with respect to the spraying of the cleaning solution, referring to fig. 3, the cleaning member 27 includes a water outlet cover 273, and a plurality of spraying grooves are opened on one side of the water outlet cover 273, which is away from the cylinder 21, and extend along the length direction of the water outlet cover 273. The water outlet cover 273 is connected with a spray head through threads, and the water outlet end of the spray head 271 is exposed from the spray groove. In this embodiment, a plurality of spray heads 271 may be installed in one spray tank.

When the cleaning liquid is conveyed into the diversion cavity 22, the cleaning liquid is conveyed from the diversion cavity 22 to the spray head 271, and the cleaning liquid is sprayed out by the spray head 271. Through setting up a plurality of grooves of spraying, set up a plurality of shower nozzles 271 in every groove of spraying, spray away the washing liquid respectively by each shower nozzle 271, can realize covering on a large scale to the surface of camera from the even surface of spraying the camera of a plurality of positions and angle with the washing liquid to the improvement is to the efficiency of cleaing away of camera surface adhesion's pollutant.

On the contrary, if the cleaning liquid is sprayed onto the camera from one spray head 271, the camera is impacted by the cleaning liquid only in one direction, so that the stress is larger at the position, and meanwhile, the cleaning liquid can not effectively cover the camera surface. The arrangement of the ejection head 271 according to the present embodiment solves this problem.

In order to realize the adjustment and control of the spraying direction of the sprayed cleaning liquid, referring to fig. 3, the cleaning member 27 of the present embodiment adopts the following structure:

the cleaning member 27 includes a water flow guide 272, and an edge portion of one side of the water flow guide 272 is rotatably mounted on the water outlet cover 273, and the direction of the rotation axis of the water flow guide 272 coincides with the length direction of the water outlet cover. The water flow guide 272 is shielded in front of the head 271 in the water discharge direction of the head 271.

When the shower head 271 sprays the cleaning liquid, the cleaning liquid impinges on the water flow guide 272, and the spraying direction of the cleaning liquid is changed due to the shielding and guiding action of the water flow guide 272. Eventually, the cleaning solution is sprayed onto the camera in a direction defined by the water flow guide 272.

Pollutants on the surface of the camera can be attached to various positions on the surface of the camera, and along with the cleaning process, pollutants on some positions on the surface of the camera can be cleaned, and pollutants on other positions can not be cleaned; or the cleaning liquid sprayed by the current nozzle 271 cannot directly and effectively clean the pollutants on the camera.

The cleaning liquid sprayed from the spray head 271 is changed in the spraying direction after it impinges on the water flow guide 272.

The water flow guide is rotated to adjust its inclination angle, and as the inclination angle of the water flow guide is changed, since the washing liquid is sprayed in a direction defined by the water flow guide, the spraying direction of the washing liquid is finally changed along with the direction of the water flow guide. Therefore, the direction of the washing liquid is adjusted and controlled by adjusting the direction of the water flow guide, so that the washing liquid is sprayed onto the camera from multiple directions and angles, and the accuracy and efficiency of washing are improved.

In this embodiment, the water flow guide 272 is used to guide and adjust the output direction of the cleaning liquid, and the specific process is as follows:

referring to fig. 4, the cleaning member 27 further comprises a spring plate 274, and one end of the spring plate 274 is rotatably connected to the outlet cover by a bolt, and the direction of the rotating shaft of the bolt is consistent with the length direction of the outlet cover.

The inclination angle of the spring plate 274 can be adjusted by rotating the bolt, and the water flow guide 272 is further driven to rotate, so as to adjust the inclination angle of the water flow guide 272.

After being sprayed from the spray head 271, the cleaning liquid first impacts the water flow guide 272 and then is sprayed onto the camera to be cleaned under the shielding effect of the water flow guide 272. In this embodiment, after the inclination angle of the water flow guide 272 is changed, the output direction of the cleaning liquid that impacts thereon, that is, the flow direction of the cleaning liquid that is finally sprayed onto the camera is changed accordingly, thereby realizing the adjustment of the large spraying direction of the cleaning liquid, and realizing the accurate cleaning of contaminants such as dust on the surface of the camera.

Through the further adjustment to the structure of rivers guide 272, realize the fine setting to the direction of spraying of washing liquid, further improve the degree of accuracy that sprays the liquid and spray, concrete process is as follows:

referring to fig. 4, the water flow guide 272 includes a guide bottom plate 2721, and a working surface of the guide bottom plate 2721 is a concave curved surface. After the cleaning liquid impacts the side wall of the guide bottom plate 2721, the cleaning liquid flows under the guide of the curved surface, the resistance action of the curved surface is small, and the cleaning liquid can flow out conveniently and smoothly.

Referring to fig. 5, mounting seats 2725 are fixedly connected to one side of the working surface of the guide base plate 2721 by bolts, rotation shafts 2724 are mounted on the two mounting seats 2725, guide side plates 2722 are fixed to the rotation shafts 2724, drainage grooves 2723 are concavely formed in both sides of the guide side plates 2722, and side walls of the drainage grooves 2723 are curved surfaces that are concave inward.

When the cleaning liquid impacts on the guide side plate 2722, the cleaning liquid flows along the direction guided by the drainage grooves 2723. The rotating shaft 2724 is rotated by a certain angle, and then the rotating shaft 2724 and the guide side plate 2722 are locked by threads. The rotation shaft 2724 rotates to rotate the guide side plate 2722, thereby adjusting the inclination angle of the guide side plate 2722. The spraying direction of the cleaning liquid is guided and limited by the guide side plate 2722, and then the direction of the cleaning liquid which is impacted on the guide side plate 2722 and is sprayed out finally is changed along with the change of the inclination angle of the guide side plate 2722, so that fine adjustment of the spraying direction of the cleaning liquid is realized.

In summary, the adjustment of the direction in which the cleaning liquid guided by the water flow guide 272 is finally sprayed is achieved by the adjustment of the inclination angle of the water flow guide 272 and the adjustment of the inclination angle of the guide side plate 2722. Through the adjustment, make the washing liquid by accurate spraying to the pollutant on camera surface to high-efficient accurate thoroughly clear up the pollutant on camera surface.
