[0034] The cleaning component 3 includes a rectangular block 35, which is slidably connected to the inner wall of the through groove 4 11. A threaded rod 38 is threadedly connected to the lower surface of the rectangular block 35. The threaded rod 38 is a prior art and has the characteristics of self-locking up and down. It will not rotate when the motor 31 is not started. The lower surface of the threaded rod 38 is fixedly connected to the motor 31. The motor 31 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The motor 31 is fixedly connected to the right end of the lower surface of the camera 2. A through groove 2 9 is provided on the right surface of the top of the bracket 1. The connecting strip 7 is slidably connected to the inner wall of the through groove 2 9. The front surface of the convex block 4 is provided with a groove, and the rear end of the insertion rod 6 contacts the inner wall of the groove.

[0035] Reference Figure 1 , Figure 6 A through groove 5 12 is provided on the inner wall of the top of the bracket 1, and a rectangular plate 5 is slidably connected to the inner wall of the through groove 5 12, and a plug rod 6 is fixedly connected to the rear surface of the rectangular plate 5, and a connecting strip 7 is fixedly connected to the right surface of the rectangular plate 5. The rear surface of the right end of the connecting strip 7 is threadedly connected with a bidirectional threaded column 8. The bidirectional threaded column 8 is a prior art, and its outer wall is provided with two groups of threads with different rotation directions to ensure that when the bidirectional threaded column 8 is rotated, the structure of the threaded connection of the outer wall will move in relative and opposite directions. At the same time, it has the characteristics of self-locking front and back to ensure that it will not rotate by itself, making the connection more stable.

[0036] Reference Figure 3 , Figure 4The rear surface of the rectangular block 35 is fixedly connected with a rectangular sliding shell 36, and the rectangular sliding shell 36 is slidably connected to the inner wall of the through groove 411. The inner wall of the rectangular sliding shell 36 is elastically connected with a card block 39 through a spring 1 310. The spring 1 310 always pushes the card block 39 to move to the left through its own elasticity. When the rectangular shell 33 is fixed to the inner wall of the front end of the camera 2, the spring 1 310 will ensure that the card block 39 is always in contact with the inner wall of the rectangular groove 312 by its own elasticity when the card block 39 is not subjected to force, thereby ensuring the stability of the limit. The card block 39 is slidably connected to the rectangular sliding shell 36 The inner wall of the block 39 is an inclined surface, which improves the quickness of the installation of the rectangular shell 33. One end of the spring 310 is fixedly connected to the right surface of the block 39, and the other end of the spring 310 is fixedly connected to the inner wall of the rectangular sliding shell 36. The right end of the front surface of the block 39 is fixedly connected with a push plate 37, and the push plate 37 penetrates and slides to the inner wall of the through groove three 10. The through groove four 11 is connected to the through groove three 10 to ensure the smoothness of the coordination between the structures. The front surface of the rectangular sliding shell 36 is provided with a through groove 311, and the rear end of the push plate 37 is slidably connected to the inner wall of the through groove 311.

[0037] Reference Figure 3 , Figure 5 The front inner wall of the camera 2 is in contact with a scraper 32, and the bottom end of the scraper 32 is tightly attached to the lens end face of the camera 2 to ensure the cleaning effect. The upper surface of the scraper 32 is fixedly connected with a rectangular shell 33, and the inner wall of the rectangular shell 33 is elastically connected with a top plate 314 through a second spring 315. The second spring 315 itself has a certain elasticity. When the cleaning cotton 34 contacts the camera 2, the second spring 315 will be squeezed through the top plate 314. At this time, the second spring 315 will enable the cleaning cotton 34 to be tightly attached to the camera 2 through its own elasticity, thereby enhancing the cleaning effect. The top plate 314 is slidably connected to the inner wall of the scraper 32, and the second spring 315 is elastically connected to the top plate 314. One end of spring 315 is fixedly connected to the inner wall of the scraper 32, and the other end of spring 315 is fixedly connected to the front surface of the top plate 314. A rectangular groove 312 is set on the right surface of the scraper 32, and the left end of the block 39 contacts the inner wall of the rectangular groove 312. The rear surface of the top plate 314 is magnetically connected to a magnetic plate 313. The top plate 314 is made of iron. The magnetic plate 313 itself has a certain magnetism. When it contacts the top plate 314, it will be sucked on the rear surface of the top plate 314. The rear surface of the magnetic plate 313 is fixedly connected to a cleaning cotton 34. The rear surface of the cleaning cotton 34 contacts the inner wall of the front end of the camera 2 near the upper side of the scraper 32.

[0038] Working principle: When in use, when the bracket 1 and the camera 2 need to be installed, you only need to pick up the camera 2 and insert the convex block 4 fixedly connected to its lower surface into the inner wall of the top of the bracket 1. At this time, you can rotate the two-way threaded column 8, and the two-way threaded column 8 drives the connecting strip 7 threadedly connected to its outer wall to move. The connecting strip 7 will drive the rectangular plate 5 to slide on the inner wall of the through groove 5 12, and the rectangular plate 5 will push the insertion rod 6 to move, so that the insertion rod 6 is inserted into the inner wall of the groove on the front surface of the convex block 4. In this way, the bracket 1 and the camera 2 can be fixedly connected together. When disassembling, you only need to reverse the two-way threaded column 8, and the subsequent structural coordination method is the same as above.

[0039] In humid weather, if the end is found to be blurry, you only need to start the motor 31. The motor 31 will mobilize the threaded rod 38 to rotate. At this time, the rectangular block 35 threadedly connected to the outer wall of the threaded rod 38 will move along with its rotation. The rectangular block 35 will drive the rectangular sliding shell 36 to move. The rectangular sliding shell 36 will drive the scraper 32 to move through the block 39. The scraper 32 will drive the scraper 32 to move, and the mixture of water mist and dust adhered to the lens of the camera 2 will be cleaned. At the same time, the cleaning cotton 34 follows the scraper 32 to clean the remaining water stains.

[0040] When it is necessary to clean and replace the scraper 32 and the cleaning cotton 34, it is only necessary to drag the push plate 37, and the push plate 37 will drive the block 39 to move and squeeze the spring 1 310 until the block 39 is completely separated from the inner wall of the rectangular groove 312. At this time, the scraper 32 can be removed and the scraper 32 can be cleaned. The cleaning cotton 34 can be pulled to separate the magnetic plate 313 from the top plate 314. This can clean and replace the cleaning cotton 34, which improves practicality. When installing, it is only necessary to place the cleaning cotton 34 on the rear end of the scraper 32 and make the magnetic plate 313 and the top plate 314 magnetically attracted together. At this time, the scraper 32 can be removed. 32 is placed into the inner wall of the front end of the camera 2, and the scraper 32 is aligned with the block 39. At this time, the block 39 will push the block 39 to move to the right along the inclined surface of the block 39, and the block 39 will squeeze the spring 1 310 until the block 39 overlaps with the rectangular groove 312. At this time, the spring 1 310 will push the block 39 to insert into the inner wall of the rectangular groove 312 through its own elasticity. In this way, the installation is successful, and in this process, the cleaning cotton 34 will be forced to squeeze the spring 2 315 through the top plate 314. The spring 2 315 will use its own elastic characteristics to make the cleaning cotton 34 close to the lens of the camera 2, thereby enhancing the cleaning effect.
