[0031] The dustproof net 42 is vertically built into the connection frame 41, and the dustproof net 42 is opposite to the air inlet 32 ​​opened in the fixed guide rail 31, so as to ensure that the dustproof net 42 can achieve efficient dust blocking protection and reduce the occurrence of dust pollution.

[0036] Here’s how it works:

[0037] When the active air intake structure for SVG heat dissipation in the cabinet is to be used, the active air intake structure 3 can be installed on the side wall of the box body 1, so that the air duct 35 provided inside the active air intake structure 3 is opposite to the SVG device body 2 provided inside the box body 1. When the heat dissipation fan 33 provided inside the active air intake structure 3 is driven, the external air can quickly pass through the air intake hole 32 provided inside the fixed guide rail 31 and enter the inside of the box body 1. In combination with the guiding effect of the air duct 35 connected to the right side of the heat dissipation fan 33, the external air can quickly contact the SVG device body 2, so that the external air can achieve efficient auxiliary wind heat dissipation for the electrical components provided inside the SVG device body 2, thereby avoiding the occurrence of overheating and damage to the SVG device body 2.

[0038] If the SVG device body 2 of different specifications needs to be actively cooled and air intake is required, the first lock buttons 34 provided at the four corners of the cooling fan 33 can be rotated in sequence to unlock the four corners of the cooling fan 33 in advance, thereby, in conjunction with the guide grooves provided on the left and right sides of the fixed guide rail 31, the active cooling position of the cooling fan 33 can be conveniently moved up and down to meet the cooling requirements of the SVG device body 2 of different specifications. In addition, because the air guide duct 35 is configured in a telescopic shape as a whole, the cooling fan 33 can still achieve stable air delivery and cooling coordination when it is moved up and down;

[0039] Secondly, in order to ensure that dust carried by the external air is not easy to enter the SVG device body 2 during active heat dissipation, a detachable dustproof device 4 is provided on the left side of the fixed guide rail 31 to achieve stable dustproof protection, that is, the dustproof net 42 installed inside the connection frame 41 is opposite to the multiple air inlet holes 32 equidistantly opened inside the fixed guide rail 31. In this way, when the external air enters the box body 1, it needs to pass through the dustproof net 42 in advance. Therefore, with the filtering and purification effect of the dustproof net 42, the dust inside the external air can be filtered and blocked, ensuring the cleanliness of the incoming air, and achieving stable dustproof protection for the equipment inside the box body 1.

[0040] In order to ensure the convenience of the overall use of the dustproof net 42, a clamping assembly 44 is also provided at the upper end of the connecting frame 41, so as to realize the convenient disassembly and assembly of the connecting frame 41 as a whole. That is, when disassembly is required, the rotating rod 443 connected to the left side of the rotating block 442 can be rotated. As the rotating rod 443 rotates, the pressing block 444 threadedly connected to the external thread on the outer side of the rotating rod 443 will move along the inside of the rotating block 442, so as to release the pressing and locking effect on the upper end of the connecting frame 41, so that the upper end of the connecting frame 41 can be easily disassembled. When the pressing block 444 moves to the leftmost end of the rotating block 442, the rotating block 442 can be lifted up as a whole, so that the rotating block 442 can be rotated to a vertical state along the connecting block 441. In this way, the pressing assembly 44 can be unlocked as a whole, so that the upper end of the connecting frame 41 is loosened. Therefore, the dustproof net 42 can be conveniently disassembled as a whole by directly taking the connecting frame 41 as a whole. The reinstallation steps are the opposite of the above steps. Therefore, they are not described in detail, thereby achieving the advantages of convenient disassembly and assembly of the dustproof net 42 as a whole and satisfying the convenience of use.

[0041] After the dust screen 42 has been used for a long time, a large amount of dust is easily attached to the outer surface. In order to prevent the dust from affecting the smoothness of the air intake, a cleaning component 45 is also provided on the outer side of the connecting frame 41. That is, when cleaning is required, the movable frame 451 can be grasped and the handle 453 provided on the front side of the scraper 452 can be pulled to move the scraper 452 forward as a whole. As a result, the side blocks 454 connected to the left and right sides of the scraper 452 will move forward synchronously to achieve the compression and removal of the front side abutting compression spring 455 and the rear side connected plug shaft 456. In this way, the plug shaft 456 can be quickly released from the card-locked state with the outer side of the connecting frame 41. Then, Move the movable frame 451 so that it cooperates with the limit blocks 457 set on both sides of the rear end and the sliding embedding effect of the connecting frame 41 to perform stable up and down movement. At the same time, during the movement, release the handle 453 to make the scraper 452 cooperate with the rebound force of the compression springs 455 on both sides to re-impede the outer surface of the dustproof net 42. Therefore, the staff can pull the movable frame 451 up and down to make the scraper 452 assist in achieving convenient scraping and cleaning of the dust attached to the outside of the dustproof net 42, thereby improving the fluidity of the dustproof net 42 and reducing blockage, thereby achieving the advantages of convenient scraping and cleaning of the dust attached to the outside of the dustproof net 42 and reducing the occurrence of blockage.

[0042] The utility model provides an active air intake structure for heat dissipation of SVG in a cabinet, wherein an active air intake structure 3 is provided, namely, in cooperation with a heat dissipation fan 33, a first locking button 34 and an air guide duct 35, convenient adjustment of active heat dissipation air intake can be achieved, and a main body 2 of the SVG device can be stably operated, and a detachable dustproof device 4 is provided, namely, in cooperation with an internal dustproof net 42, dust blocking can be achieved, and the occurrence of dust entry pollution can be reduced, and a clamping assembly 44 is provided, namely, a rotary rod 443 can conveniently reciprocate and drive a clamping block 444, so that the clamping block 444 moves, clamps, locks or unlocks, so as to meet the overall convenient disassembly and assembly of the dustproof net 42, thereby achieving the advantages of convenient disassembly and assembly of the dustproof net 42 as a whole and meeting the convenience of use, and a cleaning assembly 45 is provided, namely, a scraper 452 can be pushed and pulled by a movable frame 451, so as to achieve convenient scraping and cleaning of dust on the outer side of the dustproof net 42, and at the same time, a plug-in shaft 456 and a limit block 457 can be combined to achieve card-connection locking and movable guiding cooperation.
