[0029] The photoresistor model used in the present invention is MG41-23, the light resistance (the resistance of the photoresistor when it is irradiated with light is called the light resistance) of this model photoresistor is less than 5KΩ, and the dark resistance (the resistance value obtained by the photoresistor under weak light or without light) is greater than 5MΩ When in use, the transparent door body 38 of the present invention covers the front opening of the connection box 12 to prevent rainwater from entering the connection box 12, and the discharge door 40 on the collection box 39 is closed; the exhaust fan 25 is started, and the outside air enters the bearing box 2 through the shutter 27, and the dustproof net 4 can block the dust in the air. The air after filtering the dust enters the cabinet 1 through the air inlet 26, and the air carries the heat in the cabinet 1 and is discharged from the cabinet 1 under the action of the exhaust fan 25, thereby cooling the components in the cabinet 1; In the initial state, the driving block 21 on the iron plate 20 is located in the upper end of the spiral groove 17, the piston plate 6 is located in the rear part of the housing 5, and the elastic cylinder 7 is in a natural state; During the day, light enters the connection box 12 through the transparent door 38, the resistance of the photoresistor 14 is reduced by the light, the current in the path formed by the power supply 24 and the electromagnet 23 through the wire gradually increases, the magnetism generated by the electromagnet 23 increases, and under the attraction of the electromagnet 23, the iron plate 20 moves downward, the elastic band 22 is stretched, and the driving block 21 presses the spiral groove 17 with the downward movement of the iron plate 20 to rotate the shaft 13. When the shaft 13 rotates, the pull rope 16 located outside the shell 5 is wound around the shaft 13, and the end of the pull rope 16 connected to the piston plate 6 pulls the piston plate 6 forward. When the piston plate 6 moves forward, the elastic cylinder 7 stretches, the air pressure in the elastic cylinder 7 decreases, and the outside The gas enters the elastic tube 7 through the one-way air inlet valve 8 until the iron plate 20 is attracted by the electromagnet 23. At this time, the piston plate 6 contacts the inner surface of the front side plate of the housing 5. Air is stored in the elastic tube 7. The air pressure in the elastic tube 7 is the same as that in the outside. Therefore, the gas in the elastic tube 7 will not squeeze the elastic plate 10c. The elastic plate 10c on the one-way air outlet valve 10 remains in a natural state. The elastic plate 10c keeps blocking the opening of the groove 10a. The gas in the elastic tube 7 will not enter the air injection pipe 3. Moreover, during the daytime, the photoresistor 14 is continuously affected by light. The iron plate 20 can remain attracted by the electromagnet 23. The elastic tube 7 remains in an extended state under the pull of the piston plate 6 and the pull rope 16. At night, the light gradually dims. After the light dims, the resistance of the photoresistor 14 increases, the current given to the electromagnet 23 by the power supply 24 gradually decreases, and the magnetism generated by the electromagnet 23 gradually decreases. When the electromagnet 23 is not enough to attract the iron plate 20, the iron plate 20 quickly moves upward under the restoring force of the elastic belt 22, and the driving block 21 on the iron plate 20 can quickly drive the rotating shaft 13 to rotate in the opposite direction, releasing the pull rope 16 wound on the rotating shaft 13. The piston plate 6 connected to the elastic cylinder 7 is no longer pulled by the pull rope 16. Under the restoring force of the elastic cylinder 7, the elastic cylinder 7 begins to shrink. During the process of the elastic cylinder 7 shrinking backward, the air in the elastic cylinder 7 will not be discharged through the one-way air inlet valve 8. The air in the elastic cylinder 7 squeezes the elastic plate 10c, so that the elastic plate 10 c bends and deforms the lower end toward the front side of the groove 10a, the opening of the groove 10a is opened, and the gas in the elastic cylinder 7 passes through the groove 10a and then enters the air jet pipe 3, and is quickly sprayed toward the dustproof net 4 through the multiple groups of air outlet holes 11 on the air jet pipe 3, so that the dust on the dustproof net 4 is cleaned; and in the process of the elastic cylinder 7 contracting, the elastic cylinder 7 drives the piston plate 6 to move backward, and the air jet pipe 3 sprays gas toward the dustproof net 4 while also moving backward with the piston plate 6, so that the air jet pipe 3 sprays a large area of ​​the dustproof net 4 to clean the dust, and the air outlet holes 11 on the same group are arranged in a fan shape. In the process of the air jet pipe 3 moving, the cleaning range is larger, so that the dust on both sides of the dustproof net 4 cannot be cleaned, and the dust can be cleaned in all directions, thereby improving the cleaning effect; When the piston plate 6 is stationary, the rotating rod 30 is stationary with the piston plate 6, and the dustproof wool strip 43 outside the rotating rod 30 is in a natural state, covering and blocking the lower end opening of the second sliding hole 29, and the dust on the left side of the dustproof net 4 will not enter the housing 5 or the carrying box 2 on the right side of the dustproof net 4 through the second sliding hole 29; when the piston plate moves, the rotating rod 30 moves with the piston plate 6, and the rotating rod 30 pushes the nearby dustproof wool strip 43 to bend and deform, and the dustproof wool strip 43 does not affect the movement of the rotating rod 30 along the second sliding hole 29. As the rotating rod 30 continues to move, the bent and deformed dustproof wool strip 43 returns to its natural state to cover and block the second sliding hole 29; when the piston plate 6 moves forward or backward, due to the rotating rod 30, the The driving ring 32 on the rod 30 contacts the dustproof net 4, and the driving ring 32 can drive the rotating rod 30 to rotate. The dust suction sleeve 33 rotates with the rotating rod 30, and the bristles 31 on the dust suction sleeve 33 can clean the dust on the left side of the dustproof net 4 during the rotation; and when the piston plate 6 moves backward, under the joint action of the air jet pipe 3, the cleaning effect of the dustproof net 4 can be improved, and the dust suction sleeve 33 can absorb the dust blown down by the air jet pipe 3 and cleaned by the bristles 31, thereby reducing the flying of dust; the dust dropped when the bristles 31 are cleaning falls into the collection box 39 through the ash falling hole 42. After a period of time, the discharge door 40 is opened to clean the dust in the collection box 39.

[0030] Therefore, the present invention can accumulate air in the elastic cylinder 7 during the day, and release the air in the elastic cylinder 7 to clean the dust screen 4 when the light is weak at night, and with the cooperation of the dust suction part, improve the cleaning effect and reduce the flying of dust; the present invention automatically cleans the dust screen 4 through the alternation of light intensity, which saves time and effort, and avoids the problem that the dust screen 4 is not cleaned for a long time, causing the dust screen 4 to be blocked, thereby affecting the heat dissipation of the cabinet 1; when the dust suction sleeve 33 needs to be replaced or cleaned, the shutter 27 and the limit nut 34 can be removed.

[0031] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments. Without violating the spirit of the present invention, that is, within the scope of disclosure, any multiple equivalent or equivalent modifications or replacements of the technical solutions of the invention belong to the protection scope of the present invention.
