The outer wall of the rotating drum 6 is equidistantly provided with multiple holes 7, and the inner wall of the rotating drum 6 is equidistantly provided with multiple mounting grooves 8. The top wall of the rotating drum 6 is equidistantly threaded with multiple bolts 11, and the bottom ends of the multiple bolts 11 are threadedly connected with the cleaning sponge plates 9. One side of the multiple cleaning sponge plates 9 is respectively engaged with the corresponding mounting grooves 8, and then, under the rotation of the cleaning sponge plates 9, the camera 18 can be cleaned, and at the same time, cleaning liquid and clean water can be added to the inside of the cleaning shell 4, so that the cleaning effect is improved under the action of the multiple holes 7. The front side of the cleaning shell 4 is connected with a drain valve 12, and the front side of the inner bottom wall of the frame 1 is provided with a locking mechanism 2, which is used to lock the rotating shell 16 and limit the length of the cable 17;

[0033] Specifically, by engaging the middle part of the camera 18 with the top wall of the fixing frame 13, its bottom can enter the interior of the drum 6. By starting the servo motor 5, the drum 6 rotates, and multiple cleaning sponge plates 9 are installed on the inner wall of the drum 6 by bolts 11. The cleaning sponge plates 9 will also rotate synchronously during the rotation of the drum 6, so that the cleaning sponge plates 9 can clean the outer wall of the camera 18, thereby reducing the dirt and impurities adhering to the outer wall.

[0034] Reference Figure 1 、 Figure 2 and Figure 5 The locking mechanism 2 includes two fixed plates 201, the bottom walls of the two fixed plates 201 are respectively fixedly connected to the front and rear ends of the left side of the inner bottom wall of the frame 1, and the top wall of the fixed plate 201 is fixedly connected to the connecting plate 202. One side of the connecting plate 202 is fixedly connected to a swing cylinder 203. Under the drive of the swing cylinder 203, the rotating shell 204 can be rotated. One end of the swing cylinder 203 passes through the inner wall of the connecting plate 202 and is fixedly connected to the rotating shell 204. The top wall of the rotating shell 204 is fixedly connected to a rocker rod 205, and then the rotating shell 204 drives the rocker rod 205 to complete the swing. The top end of the rocker rod 205 is rotatably connected to the locking plate 207 through the torsion spring 206. Therefore, under the rotation connection of the torsion spring 206, the locking plate 207 can lock the rotating shell 16 to stop rotation;

[0035] Specifically, by starting the swing cylinder 203, one end of the cylinder will drive the rotating shell 204 to rotate. As the rotating shell 204 rotates, the rocker arm 205 will also swing accordingly. Under the rotation connection of the torsion spring 206, the locking plate 207 will swing toward the direction of the fixed frame 16, so that the locking plate 207 can be deflected at a certain angle, thereby being able to adapt to the curvature of the rotating shell 16. The deflection of the locking plate 207 enables it to apply a certain pressure to the rotating shell 16. The locking plate 207 can stop the rotating fixed frame 16 from rotating and complete the locking of the rotating shell 16, so that the whole process can be completed quickly, thereby achieving the purpose of quick locking, thereby limiting the length of the cable 17.

[0036] Reference Figure 1 、 Figure 4 and Figure 5The two locking mechanisms 2 also include two rubber pads 208, the bottom walls of the two rubber pads 208 are respectively fixedly connected to the top walls of the corresponding locking plates 207; the front side of the cleaning shell 4 is fixedly connected to a control switch 15, and the control switch 15 is electrically connected to the servo motor 5 and the swing cylinder 203 respectively; the front top of the square plate 3 is fixedly connected to a fixing frame 13, and the top wall of the fixing frame 13 is provided with an arc groove 14;

[0037] Specifically, the rubber pad 208 reduces the damage of the locking plate 207 to the cable 17 and the rotating shell 16. The control switch 15 electrically connected to the servo motor 5 and the swing cylinder 203 respectively enables the control switch 15 to open and close the device. The fixing bracket 13 and the arc groove 14 facilitate the engagement and placement of the camera 18.

[0038] Reference Figure 1 and Figure 4 The right side of the bottom wall of the frame 1 is rotatably connected to a rotating column 19, and the front and rear ends of the rotating column 19 are fixedly connected to rollers 20; a plurality of square grooves 10 are opened on one side of the multiple cleaning sponge plates 9, and the multiple square grooves 10 are designed with height differences; a push rod 21 is fixedly connected to the right side of the frame 1, and the front and rear sides of the top of the push rod 21 are fixedly connected to rubber sleeves 22;

[0039] Specifically, the rotating column 19 and the roller 20 make it easier to move the device, the multiple square grooves 10 increase the torque of the cleaning sponge plate 9, thereby improving the cleaning effect, and the push rod 21 and the rubber sleeve 22 make it easier to push the device and improve the anti-slip effect.

[0040] Working principle: When cleaning starts, the middle part of the camera 18 is engaged with the top wall of the fixing frame 13, and then its bottom enters the interior of the drum 6, so that the drum 6 is driven by the start of the servo motor 5, and the drum 6 rotates, and multiple cleaning sponge plates 9 installed on the inner wall of the drum 6 by bolts 11 rotate synchronously, so that the outer wall of the camera 18 can be cleaned by the rotation of the cleaning sponge plates 9, so as to reduce the dirt and impurities adhering to the outer wall. At the same time, a small amount of cleaning liquid and clean water are added to the inside of the cleaning shell 4. Under the rotation of the drum 6, the mixture of cleaning liquid and water can be fully mixed, and then the mixed liquid enters the interior of the drum 6 through multiple holes 7, thereby improving the cleaning effect of the outer wall of the camera 18, avoiding the corrosion damage of the camera 18 after storage, and improving the service life of the equipment;

[0041] And by starting the swing cylinder 203, one end of it drives the rotating shell 204 to rotate, so that the swing rod 205 swings together, and under the rotation connection of the torsion spring 206, the locking plate 207 swings toward the direction of the fixed frame 16, so that the locking plate 207 can deflect at a certain angle, so that it can adapt to the curvature of the rotating shell 16, so that the locking plate 207 applies a certain pressure to the rotating shell 16, so as to stop the rotating fixed frame 16 from rotating and complete the locking of the rotating shell 16, thereby achieving the purpose of quick locking.
