Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application more apparent, the following description will be made in detail with reference to the technical solutions in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments.
Because the camera is exposed in the environment for a long time, all positions on the surface of the camera are possibly polluted by dust, and only the cleaning liquid is smeared on the surface of the camera, so that the dust attached to the surface of the camera cannot be thoroughly cleaned. In response to the foregoing problems, referring to fig. 1, this embodiment provides a self-cleaning component of a monitoring camera, including a frame 1, further including:
and a cleaning mechanism 2 detachably mounted inside the frame 1 with bolts and longitudinally near the bottom of the frame 1. The cleaning mechanism 2 is used for spraying cleaning liquid to the outer surface of the camera which stretches into the cleaning mechanism 2 from the periphery of the camera, so that the preliminary cleaning of pollutants on the surface of the camera is realized.
And the wiping mechanism 3 is connected to the upper part of the frame 1 by bolts. The wiping mechanism 3 is located directly above the cleaning mechanism 2, and is used for wiping off pollutants on the surface of the camera passing through the inside of the cleaning mechanism from the periphery.
The lifting frame 4 is connected to the upper end of the frame 1 through four upright posts by threads, and the lifting frame 4 is of a circular ring structure. A storage cylinder 5 and a recovery box 6 are welded on the outer wall of the frame 1. The cleaning liquid is stored in the storage cylinder 5. The recovery tank 6 is used for recovering the cleaning liquid.
In the process, the camera is bound to the lower end of the lifting frame 4 and extends into the cleaning mechanism 2 from top to bottom in 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 periphery side, so that the camera is primarily cleaned. After that, the camera is pulled upward in the longitudinal direction, and moves upward and enters the wiping mechanism 3, and the wiping mechanism 3 surrounds the image from the circumferential side. And the pollutants on the surface of the camera are cleaned in the process of contacting the wiping mechanism 3 with the camera. In the process, the cleaning mechanism 2 sprays cleaning liquid onto the camera from the periphery, and the wiping mechanism 3 wipes the surface of the camera from the periphery, so that the complete and thorough cleaning of pollutants on the surface of the camera is realized.
Regarding the cleaning mechanism 2, a cleaning solution is sprayed on the surface of the camera so as to realize preliminary cleaning of pollutants on the surface of the camera, and the specific process is as follows:
referring to fig. 2, the cleaning mechanism 2 includes a cylinder 21, and a flow guiding chamber 22 extending along a circumferential direction of the cylinder 21 is formed in a sidewall of the cylinder 21. A micro water pump 23 is connected to the outside of the cylinder 21 by a bolt. A plurality of cleaning members 27 are bolted to the inner wall of the cylinder 21, and the plurality of cleaning members 27 are distributed at intervals along the circumferential direction of the inner wall of the cylinder 21. The miniature water pump 23 conveys the cleaning liquid to the cleaning piece 27 through the flow guide cavity 22, and the cleaning piece 27 sprays the cleaning liquid on the outer surface of the camera.
In this embodiment, since the plurality of cleaning members 27 are used and the plurality of cleaning members 27 are spaced apart along the circumferential direction of the inner cavity of the barrel 21, the camera is placed in the barrel 21. The miniature water pump 23 is used for conveying the cleaning solution in the storage cylinder 5 to the cleaning part 27 through the flow guide cavity 22, and the cleaning parts 27 are used for respectively spraying the cleaning solution onto the outer surface of the camera from different positions and angles around the camera, so that all positions of the surface of the camera can be covered by the cleaning solution, the problem that pollutants at the position of the surface of the camera cannot be effectively cleaned due to the fact that the cleaning solution is not sprayed is avoided, and the problem that the pollutants on the surface of the camera are comprehensively cleaned is solved.
In this embodiment, the cleaning solution is sprayed onto the camera through the cleaning member 27, and referring to fig. 3, the cleaning member 27 includes a water outlet cover 273, and a plurality of spraying grooves are formed on a side of the water outlet cover 273 facing away from the cylinder 21, and the spraying grooves extend along a length direction of the water outlet cover 273. A nozzle is screwed to the outlet cover 273, and the outlet end of the nozzle 271 is exposed from the spraying groove. In this embodiment, a plurality of nozzles 271 may be installed in one spray tank.
When the cleaning liquid is supplied into the guide chamber 22, the cleaning liquid is then supplied from the guide chamber 22 to the nozzle 271, and the cleaning liquid is sprayed by the nozzle 271. Through setting up a plurality of spray tanks, set up a plurality of shower nozzles 271 in every spray tank, spray out the washing liquid respectively by each shower nozzle 271, can follow the even surface of spraying the camera of a plurality of positions and angle with the washing liquid, realize covering on a large scale to the surface of camera to improve the clearance efficiency to the pollutant that the camera surface is attached.
On the contrary, if the cleaning liquid is sprayed from one nozzle 271 onto the camera, the camera is impacted by the cleaning liquid only in one direction, resulting in a large force thereat, and at the same time, the cleaning liquid may not effectively cover the image pickup surface. The arrangement of the head 271 of the present embodiment solves this problem.
In order to realize adjustment and control of the spraying direction of the sprayed cleaning liquid, referring to fig. 3, the cleaning member 27 of this embodiment adopts the following structure:
the washing member 27 includes a water flow guide 272, and an edge portion of one side of the water flow guide 272 is rotatably mounted to a water outlet cover 273, and a rotation axis direction of the water flow guide 272 coincides with a length direction of the water outlet cover. In the water outlet direction of the head 271, the water flow guide 272 is blocked in front of the head 271.
When the nozzle 271 ejects the cleaning liquid, the cleaning liquid impinges on the water flow guide 272, and the direction of the ejection 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 the direction defined by the water flow guide 272.
Contaminants on the camera surface may adhere to various locations on the camera surface, and as the cleaning process proceeds, contaminants on certain locations on the camera surface may be cleaned off, while other locations are not cleaned off; or the current cleaning solution sprayed by the spray head 271 can not directly and effectively clean pollutants on the camera.
The cleaning liquid sprayed from the spray head 271 is changed in the direction of spraying after striking the water flow guide 272.
The water flow guide is rotated to adjust the inclination angle thereof, and as the inclination angle of the water flow guide is changed, since the cleaning liquid is sprayed in a direction defined by the water flow guide, the spraying direction of the cleaning liquid is finally changed along with the direction of the water flow guide. Therefore, the direction of the water flow guide piece is adjusted to adjust and control the direction of spraying the cleaning liquid so as to meet the requirement that the cleaning liquid is sprayed onto the camera from a plurality of directions and angles, and the cleaning accuracy and efficiency are improved.
In this embodiment, the water flow guide 272 guides and adjusts the output direction of the cleaning liquid as follows:
referring to fig. 4, the cleaning member 27 further includes a spring plate 274, and one end of the spring plate 274 is rotatably coupled to the outlet cover by a bolt having a rotation axis direction coincident with a length direction of the outlet cover. The main body portion of the spring plate 274 is bolted to the back of the water flow guide on the side that directs the water flow. Rotating the bolt adjusts the inclination of the spring plate 274, which further rotates the water flow guide 272 to adjust the inclination of the water flow guide 272.
After being sprayed from the nozzle 271, the cleaning liquid first impinges on the water flow guide 272, and then is sprayed onto the cleaned camera 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 impacting on the water flow guide 272, that is, the flow direction of the final cleaning liquid sprayed on the camera is changed, so that the adjustment of the large spraying direction of the cleaning liquid is realized, and the accurate cleaning of pollutants such as dust on the surface of the camera is realized.
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, the 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 smoothly.
Referring to fig. 5, a mounting seat 2725 is fixedly connected to one side of the working surface of the guide bottom plate 2721 by bolts, a rotating shaft 2724 is mounted on the two mounting seats 2725, a guide side plate 2722 is fixed on the rotating shaft 2724, guide grooves 2723 are concavely formed in two sides of the guide side plate 2722, and side walls of the guide grooves 2723 are curved surfaces recessed inwards.
When the cleaning liquid impinges on the guide side plate 2722, the cleaning liquid flows in the direction guided by the guide groove 2723. The rotation shaft 2724 is rotated by a certain angle, and then the rotation shaft 2724 and the guide side plate 2722 are screw-locked. The rotation shaft 2724 rotates and simultaneously drives the guide side plate 2722 to rotate, so that the inclination angle of the guide side plate 2722 is adjusted. The spraying direction of the cleaning liquid is guided and limited by the guiding side plate 2722, and the direction of the cleaning liquid finally sprayed on the guiding side plate 2722 is changed along with the change of the inclination angle of the guiding side plate 2722, so that the fine adjustment of the spraying direction of the cleaning liquid is realized.
In summary, by adjusting the inclination angle of the water flow guide 272 and adjusting the inclination angle of the guide side plate 2722, the direction in which the cleaning liquid guided through the water flow guide 272 is finally sprayed is adjusted. Through the adjustment, the cleaning liquid is accurately sprayed onto pollutants on the surface of the camera, so that the pollutants on the surface of the camera are thoroughly cleaned by high efficiency and accuracy.
After the contaminants on the surface of the camera are primarily cleaned by the cleaning liquid, part of the contaminants are separated from the camera, and possibly part of the contaminants are attached to the surface of the camera, and at the same time, part of the cleaning liquid and the contaminants are mixed and stained on the surface of the camera.
In this embodiment, the adhering contaminants and a small amount of cleaning liquid on the surface of the camera are thoroughly cleaned by the wiping mechanism 3, so as to thoroughly clean the surface of the camera, and the specific process is as follows:
referring to fig. 6, the wiping mechanism 3 includes an outer ring 31, a support member 33 is fixed in the outer ring 31 by bolts, and a working end of the support member 33 faces an axial center of the outer ring 31.
