[0023] In order to make the above-mentioned purposes, features and advantages of the utility model more understandable, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0024] like Figure 1-Figure 6 As shown, the utility model provides a dustproof power cabinet, including a cabinet 1, and air guide shells 2 are arranged on both sides of the cabinet 1, and the upper and lower ends of the air guide shells 2 are open. The larger the contact area between the filter screen on the existing equipment and the outside air, the more dust is attached. By setting the air guide shell 2, it is used for air diversion, and the air is accurately introduced into the dustproof net 6. The upper and lower openings of the air guide shell 2 reduce the contact area with the outside, and reduce the attachment of dust to the dustproof net 6. The side wall of the air guide shell 2 is connected to the inside of the cabinet 1, and the inner side of the upper and lower openings of the air guide shell 2 is provided with evenly distributed dustproof net fixing frames 14, and the dustproof net 6 is placed between the upper and lower rows of dustproof net fixing frames 14. The dustproof net 6 is provided with a dust removal mechanism for dust removal outside; the dust removal mechanism is connected to a transmission assembly for driving. The cabinet 1 surface is connected with a cabinet door through a hinge, and the cabinet door and the cabinet 1 surface are provided with through holes for installing instruments and operating panels.

[0025] The dustproof net fixing frame 14 and the dustproof net 6 are provided to effectively prevent dust from entering the cabinet 1. The uniform distribution of the dustproof net fixing frame 14 and the provision of the dustproof net 6 can block the entry of dust particles and keep the cabinet 1 clean. This can prevent dust from damaging electrical equipment and improve the reliability and stability of the equipment. The dustproof net 6 can be cleaned by the dust removal mechanism to prevent a large amount of dust from adhering to the surface of the dustproof net 6 and affecting air circulation. The transmission component is used to drive the dust removal mechanism so that the dust removal mechanism can operate normally.

[0026] Furthermore, the dust removal mechanism includes a slide plate 7, symmetrical side fixing plates 9 are fixed on both sides of the slide plate 7, a slide plate 2 12 is arranged between the two symmetrically arranged side fixing plates 9, the slide plate 1 7 and the slide plate 2 12 are located on the two sides of the dustproof net 6, and the outer walls of the slide plate 1 7 and the slide plate 2 12 are provided with through holes corresponding to the positions, two scrapers 8 are arranged in the through hole of the slide plate 1 7, and a roller 13 is arranged in the through hole of the slide plate 2 12; one side of the scraper blade 8 is arc-shaped, and the arc-shaped surfaces of the two scrapers 8 are close to each other, and the outer wall of the roller 13 is provided with evenly distributed spherical protrusions, and the transmission component includes a rack 10, the rack 10 is fixed to the outer wall of the side fixing plate 9, the rack 10 is meshed with a transmission gear 11, and one end of the transmission gear 11 is connected to the transmission rod 4.

[0027] Slide plate 1 7 and slide plate 2 12 play the role of fixing scraper blade 8 and roller 13. When slide plate 1 7 and slide plate 2 12 slide up and down, fixed scraper blade 8 and roller 13 will slide along the surface of dustproof net 6, roller 13 will lift one side of dustproof net 6, so that dustproof net 6 protrudes toward scraper blade 8, and the protruding part of dustproof net 6 is cleaned by two scrapers 8. At the same time, spherical protrusions are provided on the surface of roller 13, which can push out dust in the gap of dustproof net 6 and improve the cleaning effect of scraper blade 8. When driving rod 4 rotates, it can drive transmission gear 11 to rotate, and transmission gear 11 can drive rack 10 to move, and rack 10 drives slide plate 1 7 and slide plate 2 12 to move up and down.

[0028] Furthermore, one end of the transmission rod 4 passes through the cabinet 1, and the end of the transmission rod 4 passing through the cabinet 1 is connected to a transmission disc 1, a transmission belt 5 is provided on the outside of the transmission disc 1, and a transmission disc 2 is provided on the inner side of the other end of the transmission belt 5, the transmission disc 2 is connected to the fan 3, and the transmission disc 2 is connected to the rotating shaft of the fan 3, the outer diameter of the transmission disc 2 is smaller than the outer diameter of the transmission disc 1, and the fan 3 is located at a position where the cabinet 1 is connected to the air guide shell 2.

[0029] The combination of the rack 10, the transmission gear 11 and the transmission rod 4 can realize the transmission force transmission, so that the dust removal mechanism can move, which can ensure the stability and reliability of the dust removal mechanism and ensure its normal operation. At the same time, the fan 3 can drive the transmission disc 2 to rotate, and the transmission disc 2 with a smaller outer diameter can drive the transmission disc 1 with a larger outer diameter to rotate through the transmission belt 5, so as to drive the transmission rod 4 to rotate. In this way, during the cooling process of the fan 3, the dustproof net 6 is cleaned by the scraper 8 and the roller 13. The roller 13 lifts the part of the dustproof net 6 that needs to be scraped to form an arc-shaped protrusion. At this time, the scraper 8 scrapes the protruding part, and at the same time, the roller 13 blocks the other side of the top protrusion of the dustproof net 6 as a concave part. At this time, when the scraper 8 scrapes the dust from the arc-shaped protrusion, the dust will not enter the interior of the device, and the slide plate 1 7 and the slide plate 2 12 can be driven to move up and down at any time, so that the scraper 8 and the roller 13 clean the dustproof net 6, avoid a large amount of dust adhering to the surface of the dustproof net 6, and improve the effect of air guide cooling.

[0030] The above-mentioned embodiments only express one or more implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
