Technical Field

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

[0002] An electrical cabinet is a carrier used to install and protect electrical equipment. It is usually made of metal materials and has dustproof, waterproof, corrosion-resistant, explosion-proof and other properties, and can withstand a certain degree of mechanical shock and vibration. Electrical cabinets are widely used in industrial production and public facilities. They can be used to install electrical equipment such as transformers, switches, controllers, and computer equipment. Electrical equipment running inside the electrical cabinet will generate electromagnetic radiation and heat, etc. These factors will cause tiny particles in the air to accumulate on the surface or inside of the equipment, reducing the service life and reliability of the electrical equipment. Therefore, there is a special need for a dust removal device for electrical cabinets.

[0003] Existing electrical cabinets have heat dissipation ports on their outer surfaces for heat dissipation, and filters are installed at the heat dissipation ports to prevent dust and dissipate heat. However, after long-term use, the filters at the heat dissipation ports will be clogged with dust, which will affect the heat dissipation efficiency and the service life of the electrical equipment.

[0007] A dust removal mechanism is installed on the inner wall of the dust isolation chamber at the first heat dissipation strip hole, and the dust removal mechanism includes four fixed blocks installed on the inner wall of the dust isolation chamber at the four corners of the first heat dissipation strip hole, a screw rod installed between the two top fixed blocks, a guide rod installed between the two bottom fixed blocks, a driving motor installed on one side of the screw rod, two sliding blocks respectively located on the screw rod and the guide rod, and a dust removal brush plate installed between the two sliding blocks, wherein the brush of the dust removal brush plate contacts the dustproof net in the first heat dissipation strip hole.

[0008] Furthermore, the aperture diameter of the dust-proof net in the first heat dissipation strip hole is larger than the aperture diameter of the dust-proof net in the second heat dissipation strip hole.

[0009] Furthermore, a wedge-shaped rainproof plate is installed on the outer wall of the electrical cabinet at the first heat dissipation strip hole, and the bottom of the rainproof plate and one side close to the first heat dissipation strip hole are both open structures.

[0010] Furthermore, a collection box is slidably mounted on the bottom of the dust isolation chamber, and a buckle groove is mounted on one end of the outer side of the collection box.

[0011] Furthermore, the inner walls on both sides of the bottom of the dust isolation chamber are both slope structures inclined toward the collection box at the middle bottom.

[0012] Furthermore, an inspection plate is installed on the front side of the dust isolation chamber via four fixing bolts.

[0013] Furthermore, connecting blocks are installed on the top and bottom of the dust removal brush plate, a docking threaded shaft is installed on one side of the inner side of the connecting block, grooves and slots matching the connecting block and the docking threaded shaft are provided on the sliding block, and a nut is installed on the docking threaded shaft.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The device dissipates heat through the first heat dissipation strip hole and the second heat dissipation strip hole, and prevents dust through the dust-proof net at the heat dissipation strip hole. At the same time, the dust-proof net at the external heat dissipation strip hole can be regularly cleaned through the dust removal mechanism to sweep the dust adhering to the dust-proof net and fall inside to prevent the heat dissipation strip hole from being blocked. At the same time, through the design of the dust isolation chamber, the dust that falls inside after being swept will not enter the interior of the electrical cabinet, but will fall into the dust isolation chamber and be collected, thereby further ensuring the dust-proof effect and the heat dissipation efficiency of the electrical cabinet.
