Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet ventilation technology, specifically a dustproof power distribution cabinet ventilation mesh. Background Technology

[0002] Distribution cabinets are widely used in various electrical systems. They need to be dustproof, waterproof and have good heat dissipation capabilities. Most existing distribution cabinets are equipped with ventilation openings for heat dissipation. These ventilation openings can reduce the internal temperature during operation of the distribution cabinet, and dustproof measures such as dust screens are also installed on the ventilation openings.

[0003] Existing technology, such as the disclosure number "CN209448254U", discloses a dustproof, ventilated, and heat-dissipating power distribution cabinet, including a cabinet body, a cabinet door hinged to the cabinet body, and an exhaust vent on the outer wall of the cabinet body. It also includes a bladeless ceiling fan mounted on the top wall of the cabinet body, a U-shaped frame mounted on the top of the outer wall of the cabinet body, and a dustproof net mounted on the outer wall of the cabinet body at the exhaust vent. The U-shaped frame is equipped with a rain shield and a drive mechanism that drives the rain shield to slide along the length of the dustproof net. The rain shield is equipped with a dust removal component for removing dust accumulated on the dustproof net. This power distribution cabinet can prevent dust and rainwater from entering the cabinet, improving the heat dissipation effect on electronic equipment and extending the service life of the power distribution cabinet.

[0004] However, this distribution cabinet has a problem: because heat dissipation and dust prevention are inextricably linked, when the dust filter needs to be replaced, the heat dissipation system also needs maintenance. Therefore, the dust filter lacks a quick and easy installation and fixing function, requiring manual screwing of bolts into the threaded holes. Furthermore, the bladeless fan used for heat dissipation is fixed, making disassembly and maintenance inconvenient, time-consuming, and labor-intensive. In view of this, we propose a dustproof distribution cabinet ventilation screen. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] A dustproof distribution cabinet ventilation mesh, such as Figures 1-5As shown, the cabinet includes a cabinet body 1. The top outer wall of the cabinet body 1 has a ventilation opening and a T-shaped socket. The inner wall of the T-shaped socket of the cabinet body 1 has a square groove. The top inner wall of the cabinet body 1 is equipped with a quick-release device 2. The quick-release device 2 includes a ventilation plate 21, a cooling fan 22, a T-shaped pin 23, a filter frame 24, a filter screen 25, and a top pin 26. The ventilation plate 21 is located on the top outer wall of the cabinet body 1. The top surface of the ventilation plate 21 near the ventilation opening of the cabinet body 1 has a placement groove. The cooling fan 22 is fixedly installed on the side of the ventilation plate 21 near the inner wall of the cabinet body 1 by bolts. The T-shaped pin 23 is fixedly installed on the side wall and bottom of the ventilation plate 21. The filter frame 24 is slidably installed on the inner wall of the placement groove of the ventilation plate 21. The filter screen 25 is fixedly installed on the inner wall of the filter frame 24. The top pin 26 is fixedly installed on the top of the filter frame 24.

[0023] The top surface of the ventilation plate 21 has slots at both ends. The T-shaped pin 23 is slidably installed on the inner wall of the T-shaped socket of the cabinet 1. The T-shaped pin 23 located on the side wall of the ventilation plate 21 has a cavity inside. The slots of the ventilation plate 21 and the cavity of the T-shaped pin 23 are connected.

[0024] The quick-loading / unloading device 2 also includes a C-shaped insert 27, a locking block 271, a locking groove 272, a limiting plate 28, a spring 29, an abutting arc rod 210, a rotating shaft 211, a torsion spring cylinder 212, an abutting plate 213, a locking hook 214, and a locking post 215. The C-shaped insert 27 is slidably installed on the inner wall of the slot in the ventilation plate 21. The locking block 271 is symmetrically and fixedly installed on the bottom surface of the top middle of the C-shaped insert 27. The locking groove 272 is opened at the top middle of the ventilation plate 21. The limiting plate 28 is fixedly installed on the inner wall of the middle end of the slot in the ventilation plate 21. The spring 29... The contact arc rod 210 is slidably installed between the limiting plate 28 and the C-shaped plug 27 at the connection between the inner wall of the cavity of the T-shaped pin 23 and the slot of the ventilation plate 21. The rotating shaft 211 is fixedly installed in the cavity of the T-shaped pin 23. The torsion spring cylinder 212 is rotatably installed on the outer wall of the rotating shaft 211. The contact plate 213 is fixedly installed on the outer wall of the torsion spring cylinder 212 perpendicular to the outer wall of the contact arc rod 210. The hook 214 is fixedly installed on the outer wall of the torsion spring cylinder 212 perpendicular to the outer wall of the contact plate 213. The locking post 215 is fixedly installed on the inner wall of the square groove of the cabinet 1.

[0025] The two ends of the C-shaped insert 27 are arc-shaped near the bottom of the cavity of the T-shaped pin 23, and the C-shaped insert 27 passes through and slides on the top of the limiting plate 28. The locking block 271 has a certain degree of flexibility and is located on the locking trajectory of the locking slot 272.

[0026] The arc surface of the contact arc rod 210 is located on the movement trajectory of the arc surfaces at both ends of the C-shaped insert rod 27. The other end of the contact arc rod 210 is in contact with the contact plate 213. A torsion spring is provided between the inner wall of the torsion spring cylinder 212 and the rotating shaft 211. The hook 214 is located on the snapping trajectory of the snap post 215.

[0027] The dustproof distribution cabinet ventilation screen of this utility model has a problem in use. Because heat dissipation and dust prevention are inextricably linked, the heat dissipation system also needs maintenance when the dustproof screen needs to be replaced. Therefore, the dustproof screen lacks a quick installation and fixing effect, requiring manual screwing of bolts into the threaded holes, which is extremely inconvenient. Therefore, the following method is proposed: First, insert the filter frame 24 into the placement groove on the top surface of the ventilation plate 21 to quickly install the filter screen 25. When quickly installing the ventilation plate 21 and the cooling fan 22 into the ventilation opening of the cabinet 1, align the T-shaped pin 23 with the T-shaped socket on the cabinet 1, push it inward, and then press down on the C-shaped rod 27. The C-shaped rod 27 drives the locking block 271 to insert into the locking slot 272 for fixation. Simultaneously, as the C-shaped rod 27 slides downward, the arc-shaped surface at the bottom contacts the abutment. The arc-shaped surface of the arc rod 210 causes the abutting arc rod 210 to slide inward on the inner wall of the cavity of the T-shaped pin 23. After the abutting arc rod 210 contacts the abutting plate 213, the abutting plate 213 causes the torsion spring cylinder 212 on the rotating shaft 211 to rotate counterclockwise. The torsion spring cylinder 212 causes the hook 214 to rotate counterclockwise. After the hook 214 rotates to ninety degrees, it will hook onto the locking post 215 on the inner wall of the square slot of the cabinet 1, thereby completing the quick fixation of the ventilation plate 21 and the cooling fan 22.

[0028] When disassembly is required, after the locking block 271 on the C-shaped insert 27 releases the restriction on the slot 272, the C-shaped insert 27 will pop upward under the influence of the spring 29 on the limiting plate 28 of the ventilation plate 21 slot. After the abutment plate 213 releases the abutment of the abutment arc rod 210, the torsion spring in the torsion spring cylinder 212 will drive the hook 214 to return to a 90-degree angle with the abutment plate 213, completing the quick disassembly of the ventilation plate 21 and the cooling fan 22. By adopting the linkage buckling mechanism of the T-shaped pin 23 and the C-shaped insert 27, the dust filter 25 and the cooling fan 22 can be quickly installed and removed. During installation, simply push in the T-shaped pin 23 and press down the C-shaped insert 27 to trigger the hook 214 to lock the cabinet 1; during disassembly, after releasing the locking block 271 of the C-shaped insert 27, the spring 29 and the torsion spring cylinder 212 will automatically return to their original positions, causing the hook 214 to disengage from the locking post 215. This design avoids the cumbersome operation of traditional bolt fixing, significantly improves the maintenance efficiency of the heat dissipation system, and ensures a stable combination of dust prevention and heat dissipation.
