[0023] The rotating mechanism 200 is used to drive the heat dissipation and dust collection mechanism 300 and the cleaning mechanism 500 to perform reciprocating motion. The heat dissipation and dust collection mechanism 300 is used to cool the outer wall of the control device body 101 and absorb the dust floating on the outer wall surface of the heat dissipation shell 102 after cleaning by the cleaning mechanism 500 to the outside of the heat dissipation shell 102.

[0024] Reference Figure 2-Figure 4 The rotating mechanism 200 includes a mounting plate 201, a driving motor 202, a screw 203 and a moving block 204. The mounting plate 201 is provided on the side wall of the heat dissipation shell 102, and the driving motor 202 is installed on the mounting plate 201. The output end of the driving motor 202 passes through the side wall of the heat dissipation shell 102 to connect the screw 203. The other end of the screw 203 is rotatably matched with the inner wall of the other side of the heat dissipation shell 102. A moving block 204 is slidably provided on the screw 203. The side wall of the moving block 204 is slidably matched with the inner wall of the heat dissipation shell 102. A thread matching the screw 203 is provided in the moving block 204.

[0025] The driving motor 202 is started to drive the screw rod 203 to rotate, and the screw rod 203 cooperates with the moving block 204 to realize the reciprocating motion of the moving block 204.

[0026] Reference Figure 2-Figure 5 : The heat dissipation and dust collection mechanism 300 includes a rotating blade 301, a dust collection cover 302, a first gear 303, a dust removal pipe 304, a connecting pipe 305, a connecting block 306 and a rack 307. A rack 307 is installed on the inner wall of the heat dissipation shell 102, a connecting block 306 is provided on the side wall of the moving block 204, and the side wall of the other end of the connecting block 306 is connected to the dust collection cover 302. A connecting pipe 305 is rotatably provided on the inner wall of the dust collection cover 302, and a rotating blade 301 is provided on the outer wall of the connecting pipe 305 away from the connecting block 306. The other end of the connecting pipe 305 is connected to the dust removal pipe 304, and the other end of the dust removal pipe 304 passes through the side wall of the heat dissipation shell 102.

The dust collection cover 302 is open outward at one end close to the outer wall of the control device body 101.

[0027] When the moving block 204 drives the connecting block 306 to move toward the driving motor 202, the first gear 303 rotates on the rack 307 to realize the rotation of the rotating blade 301 during the movement, and the rotating blade 301 cools down and dissipates heat on the outer wall of the control device body 101. When the moving block 204 drives the connecting block 306 to move away from the driving motor 202, the rotating blade 301 reverses to absorb the dust on the outer wall of the control device body 101 and transport it to the outside of the heat dissipation shell 102 and discharge it.

[0028] Reference Figure 6: The connecting mechanism 400 includes a rotating shaft 401 and a second gear 402. One end of the rotating shaft 401 is slidably matched with the inner wall of the heat dissipation shell 102, and the other end of the rotating shaft 401 is connected to the intermittent mechanism 600. The second gear 402 is installed on the outer wall of the rotating shaft 401, and the second gear 402 is meshed with the rack 307.

[0029] The connecting block 306 drives the mounting frame 601 to perform reciprocating motion, and the mounting frame 601 drives the rotating shaft 401 to perform reciprocating motion. The rotating shaft 401 cooperates with the rack 307 to realize the second gear 402 to rotate while moving.

[0030] Reference Figure 6 The intermittent mechanism 600 includes a mounting frame 601, a ratchet 602, a return spring 603 and a pawl 604. The rotating shaft 401 is provided with a ratchet 602. The mounting frame 601 is installed on the side wall of the connecting block 306. The pawl 604 is rotatably installed on the side wall of the mounting frame 601. The two ends of the return spring 603 are respectively connected to the side wall of the mounting frame 601 and the side wall of the pawl 604. The ratchet 602 is slidably engaged with one end of the pawl 604.

[0031] The rotation of the shaft 401 drives the ratchet 602 to rotate. When the shaft 401 moves toward the driving motor 202, the ratchet 602 cooperates with the pawl 604 to achieve the ratchet 602 being engaged and not rotating. When the shaft 401 moves away from the driving motor 202, the ratchet 602 cooperates with the pawl 604 to achieve the ratchet 602 rotating, driving the first bevel gear 502 to rotate.

[0032] Reference Figure 2-Figure 6 : The cleaning mechanism 500 includes a cleaning roller brush 501, a first bevel gear 502, a rotating rod 503 and a second bevel gear 504. The first bevel gear 502 is installed on the ratchet 602 at one end close to the outer wall of the control device body 101. The inner wall of the heat dissipation shell 102 is slidably matched with the rotating rod 503. The side wall of the rotating rod 503 is connected to the side wall of the connecting block 306 through a fixed rod. The second bevel gear 504 is installed on the outer wall of the rotating rod 503. The second bevel gear 504 is meshed with the first bevel gear 502. The outer wall of the rotating rod 503 is provided with a cleaning roller brush 501 that cooperates with the outer wall of the control device body 101.

[0033] The rotation of the first bevel gear 502 drives the cleaning roller brush 501 to rotate, and the cleaning roller brush 501 drives the second bevel gear 504 to rotate. The second bevel gear 504 drives the cleaning roller brush 501 to clean the outer wall of the control device body 101. The cleaned dust floats on the outer wall of the control device body 101 and is transported to the outside of the heat dissipation shell 102 for discharge through the rotation of the rotating blades 301.

[0034] Working principle:

[0035] S1, start the driving motor 202 to drive the screw rod 203 to rotate, and the screw rod 203 cooperates with the moving block 204 to realize the reciprocating motion of the moving block 204;

[0036] S2. When the moving block 204 drives the connecting block 306 to move toward the driving motor 202, the first gear 303 rotates on the rack 307 to realize the rotation of the rotating blade 301 during the movement, and the rotating blade 301 cools and dissipates the heat of the outer wall of the control device body 101. When the moving block 204 drives the connecting block 306 to move away from the driving motor 202, the rotating blade 301 reverses to absorb and transport the dust on the outer wall of the control device body 101 to the outside of the heat dissipation housing 102 and discharge it;

[0037] S3, the connecting block 306 drives the mounting frame 601 to reciprocate, and the mounting frame 601 drives the rotating shaft 401 to reciprocate, and the rotating shaft 401 cooperates with the rack 307 to realize the second gear 402 to rotate during movement, thereby driving the ratchet 602 to rotate. When the rotating shaft 401 moves toward the driving motor 202, the ratchet 602 cooperates with the pawl 604 to realize the ratchet 602 to be engaged and not to rotate. When the rotating shaft 401 moves away from the driving motor 202, the ratchet 602 cooperates with the pawl 604 to realize the ratchet 602 to rotate, thereby driving the first bevel gear 502 to rotate;

[0038] S4. The first bevel gear 502 rotates to drive the cleaning roller brush 501 to rotate, and the cleaning roller brush 501 drives the second bevel gear 504 to rotate. The second bevel gear 504 drives the cleaning roller brush 501 to clean the outer wall of the control device body 101. The cleaned dust floats on the outer wall of the control device body 101 and is transported to the outside of the heat dissipation shell 102 by the rotating blades 301 for discharge. This prevents dust from clogging the heat dissipation holes of the control device body 101, thereby affecting the cooling and heat dissipation effect and service life of the equipment.
