[0016] 2. In the present invention, the force that drives the rotating shaft to move by the displacement of the cleaning roller cooperates with the fixed block, mounting block, torsion spring and other components in the cleaning device, so that when the fixed block moves to the side of the mounting block, the fixed block will be squeezed by the mounting block to drive the air pump to rotate, and the air gun is driven to rotate by the rotation of the air pump. At this time, the air outlet of the air gun has the effect of rotating to align with the bristles on the cleaning roller, so that the cleaning roller can be cleaned while the controller is cleaned by the air gun. The air outlet of the air gun has high precision in the rotation of the bristle area on the cleaning roller and the direction of airflow injection, and can accurately align with the position that needs to be cleaned, ensuring the targeted and effective cleaning, and further improving the cleaning effect of the cleaning roller.

[0017] 3.

When the positioning block moves to the inside of the block, the block is reset by the elastic force of the spring, and the positioning block is stuck on the side of the block. When the device is installed, the controller is protected by the fixed slide board to prevent the controller from being damaged by rain or high temperature when used outdoors. The controller is effectively protected by the fixed slide board, which greatly improves the safety of the equipment and avoids operational errors or failures caused by human factors.

Through the mutual cooperation of structures such as the threaded block 204 and the gear 210, excessive vibration or uneven movement of the cleaning roller 219 can be avoided, ensuring a smooth and stable cleaning process.

[0025] A cleaning device 3 is provided on the top of the controller 103, and the cleaning device 3 includes a rotating shaft 302, and the rotating shaft 302 is rotatably connected to the side of the cleaning roller 219, and the end of the rotating shaft 302 away from the cleaning roller 219 is fixedly connected to the air pump 301, and the air outlet of the air pump 301 is fixed with an air gun 304, the circumferential surface of the air pump 301 is fixedly connected to a fixing block 305, and the side of the controller 103 is fixedly connected to a mounting block 306.

[0026] The mounting block 306 is located on the movement trajectory of the fixed block 305, and the circumferential surface of the rotating shaft 302 is fixedly connected with a torsion spring 303. The end of the torsion spring 303 away from the rotating shaft 302 is fixedly connected to the side of the cleaning roller 219. When the fixed block 305 and the mounting block 306 are displaced, the air gun 304 automatically aligns with the bristles on the cleaning roller 219 to provide directional airflow, thereby further improving the cleaning effect of the cleaning roller 219.

[0027] The initial state of the torsion spring 303 is a relaxed state, the number of air guns 304 is set to be several, and they are arranged in a circular array on the side of the air pump 301. Through the elastic reset mechanism of the torsion spring 303, the air pump 301 and the air gun 304 can automatically return to their original positions after cleaning, ensuring that the equipment can continue to operate efficiently.

[0028] In this embodiment, the present application drives the two-way reciprocating screw 203 to rotate through the motor 202, and then the two-way reciprocating screw 203 rotates to drive the two threaded blocks 204 to move toward each other, the threaded block 204 is limited by the limit rod 205 on the side of the threaded block 204, and then the pressure plate 206 is driven to move toward each other through the displacement of the threaded block 204, thereby achieving the function of fixing the controller 103 and the circuit breaker 102, and the belt 207 is driven to rotate through the rotation of the two-way reciprocating screw 203, and then the rotating rod 209 is driven to rotate through the rotation of the belt 207, and the gear 210 is driven to rotate through the rotation of the rotating rod 209, and the gear 210 is driven to rotate through the rotation of the gear plate 212, and the gear 210 is driven to rotate. The rotation of the gear plate 212 drives the reciprocating screw 211 to rotate, and the rotation of the reciprocating screw 211 drives the threaded sleeve 213 to move, and the displacement of the threaded sleeve 213 drives the rotating shaft 216 to move, and the displacement of the rotating shaft 216 drives the gear A217 to move, so that the gear A217 engages with the rack 218 and rotates, and then the rotation of the gear A217 drives the rotating gear 215 to rotate in the opposite direction, and the rotation of the rotating gear 215 drives the rotating rod 214 to rotate in the opposite direction, thereby driving the cleaning roller 219 to rotate in the opposite direction, thereby achieving the function of cleaning the top of the controller 103, improving the cleaning effect, and preventing dust from accumulating on the top of the controller 103 and the circuit breaker 102.

[0029] The displacement of the cleaning roller 219 drives the rotating shaft 302 to be displaced, and then the displacement of the rotating shaft 302 drives the air pump 301 to be displaced, and the displacement of the air pump 301 drives the air gun 304 to be displaced, so that the air gun 304 jets further improve the cleaning effect, and the fixed block 305 is driven to rotate by the rotation of the air pump 301.

At this time, the air outlet of the air gun 304 rotates to align with the bristles on the cleaning roller 219, so that the air gun 304 effectively cleans the cleaning roller 219. When the fixed block 305 is away from the side of the mounting block 306, the rotating shaft 302 drives the air pump 301 and the air gun 304 to reset through the elastic force of the torsion spring 303, so that the controller 103 can be cleaned by the air gun 304 while the cleaning roller 219 can be cleaned, thereby improving the cleaning effect. Example 2

[0030] like Figure 1 to Figure 9 As shown, based on the same concept as the above-mentioned embodiment 1, a second embodiment is also proposed, a protective device 4 is arranged on the top of the protective plate 101, and the protective device 4 includes a mounting plate 401, the mounting plate 401 is fixedly connected to the top of the protective plate 101, and a rectangular plate 402 is fixedly connected to the side of another mounting plate 401, and a slide plate 403 is slidably connected to the inner wall of the rectangular plate 402, and a slide groove 404 is provided at the bottom of the slide groove 404, and a positioning block 413 is slidably connected to the inner wall of the slide groove 404, A telescopic rod 405 is fixedly connected to the side of the positioning block 413, the telescopic end of the telescopic rod 405 is fixedly connected to the inner wall of the slide groove 404, a support block 412 is fixedly connected to the side of the slide plate 403, a protective shell 406 is fixedly connected to the side of the mounting plate 401, a support plate 407 is fixedly connected to the inner wall of the protective shell 406, a support rod 408 passes through the side of the protective shell 406, one end of the support rod 408 is fixedly connected to a handle 410, and the other end of the support rod 408 is fixedly connected to a clamping block 411.

[0031] The bottom of the positioning block 413 is fixedly connected to the top of the threaded sleeve 213, and the circumferential surface of the support rod 408 is fixedly connected with a spring 409. The end of the spring 409 away from the support rod 408 is fixedly connected to the side of the protective shell 406. When the positioning block 413 reaches the inside of the blocking block 411, the elastic force of the spring 409 will reset the blocking block 411, thereby ensuring that the positioning block 413 can be firmly stuck to prevent the slide plate 403 from being displaced due to external interference.

[0032] The initial state of the spring 409 is a relaxed state, the side of the card block 411 is set as an inclined surface, and the side of the positioning block 413 is set as an inclined surface. The design of the card block 411 allows the positioning block 413 to be stuck into the side of the card block 411. The controller 103 is effectively protected by fixing the slide plate 403 to prevent the controller 103 from being damaged by external environmental factors such as rain or high temperature when used outdoors.

[0033] The blocking block 411 is located on the motion trajectory of the positioning block 413. The number of the fixed blocks 305 is set to be a certain number and is arranged in a circular array on the circumferential surface of the air pump 301. The design of the fixed blocks 305 can automatically control the movement of the air pump 301 and the air gun 304 through the displacement of the cleaning roller 219, thereby reducing manual intervention, improving the automation level of the system, and reducing the possibility of human operational errors.

[0034] In this embodiment, the displacement of the threaded sleeve 213 drives the positioning block 413 to be displaced, and then the displacement of the positioning block 413 drives the slide plate 403 to be displaced, and the displacement of the slide plate 403 drives the support block 412 to be displaced. When the support block 412 is displaced to the side of the protective shell 406, the inclined surface of the block 411 is squeezed so that the block 411 is displaced, and the spring 409 on the side of the protective shell 406 is squeezed. When the support block 412 is displaced to the inside of the block 411, the block 411 is reset by the elastic force of the spring 409, and the support block 412 is clamped on the side of the block 411, thereby achieving the function of fixing the slide plate 403, and achieving the effect of protecting the controller 103 by fixing the slide plate 403 after the device is installed, so as to prevent the controller 103 from being damaged by rain or high temperature when used outdoors, and when the threaded sleeve 213 is displaced in the reverse direction, it drives the telescopic rod 405 to be extended and retracted.
