Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to a dust removal device for electrical cabinets. Background Art

[0002] In the prior art, an electrical cabinet is a cabinet made of steel materials to protect components to work normally. The manufacturing materials of electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are relatively softer than hot-rolled steel plates and are more suitable for manufacturing electrical cabinets. Electrical cabinets are widely used in the chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, and so on.

[0003] After retrieval, a patent with the Chinese patent application number 202321971477.5 discloses a dust removal device for an electrical cabinet, including an electrical cabinet body. A damping mechanism is arranged on the bottom surface of the electrical cabinet body. Two symmetrically arranged guiding chutes are fixedly connected to the inner wall of the electrical cabinet body. Guide rods are slidably connected to the inner walls of the two guiding chutes. An installation box is fixedly connected to the outer surfaces of the two guide rods. Two symmetrically arranged first filter meshes are installed on the outer surface of the installation box. A chute is formed in the inner wall of the installation box. Two symmetrically arranged clamping plates are slidably connected to the inner wall of the chute. Two symmetrically arranged third buffer springs are fixedly connected to the mutually remote side surfaces of the two clamping plates, and the ends of the third buffer springs far away from the outer surfaces of the clamping plates are fixedly connected to the inner wall of the installation box.

[0029] A dust collection box 11 is fixedly installed inside the upper cavity at the top of the ventilation connection box 4 for collecting the dust filtered by the dust removal filter plates 21. The upper diversion fan 7 guides the air into the air inlet connection pipe 8, then into the air inlet connection box 9, and finally into the interior of the main body 3 of the electrical cabinet.

[0030] An air outlet connection pipe 10 is fixedly installed at the bottom end of the ventilation connection box 4, and an air outlet connection box 24 is fixedly connected to the bottom end of the air outlet connection pipe 10. A connection pressing plate 25 is fixedly connected to the top end of the air outlet connection box 24, and the connection pressing plate 25 is fixedly installed at the bottom end of the main body 3 of the electrical cabinet.

[0031] An adaptor installation groove 26 is provided in the bottom cabinet of the main body 3 of the electrical cabinet, and a ventilation connection net plate 27 is fixedly installed inside the adaptor installation groove 26. The air inside the main body 3 of the electrical cabinet enters the air outlet connection box 24 through the adaptor installation groove 26; the diversion fan 7 in the lower inner cavity of the ventilation connection box 4 discharges the air out of the main body 3 of the electrical cabinet through the air outlet connection pipe 10.

[0032] A rotating cabinet door 5 is rotatably installed on the front surface of the main body 3 of the electrical cabinet.

[0035] Working principle:

[0036] Please refer to Figures 1 to 4 , and assemble this device as shown in the figure;

[0037] As Figure 1 shown, at this time, when the rotating cabinet door 5 is closed, the connecting block 13 is squeezed to squeeze the contact switch plug 14. The contact switch plug 14 is inserted into the contact switch socket 15, the contact switch socket 15 is energized, and the flow guiding fan 7 works. At this time, the support spring 18 is in a compressed state. The upper flow guiding fan 7 extracts air from the outside and guides the air into the air inlet connecting pipe 8. After being filtered by the dust removal filter plate 21, it is guided into the air inlet connecting box 9. Finally, after being secondary filtered by the dust removal filter cylinder 23, it is guided into the main body 3 of the electrical cabinet. The lower flow guiding fan 7 discharges the air inside the main body 3 of the electrical cabinet through the adapter installation groove 26, the air outlet connecting box 24 and the air outlet connecting pipe 10, which not only ensures the heat dissipation effect inside the main body 3 of the electrical cabinet, but also prevents dust from the outside from entering the main body 3 of the electrical cabinet. When the rotating cabinet door 5 is opened, the extrusion of the connecting block 13 on the contact switch plug 14 is released. Under the action of the support spring 18, the contact switch plug 14 and the contact switch socket 15 are disengaged from the matching state, and the flow guiding fan 7 is powered off, avoiding the negative pressure generated by the air flow and sucking dust from the outside into the main body 3 of the electrical cabinet through the rotating cabinet door 5.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
