Description

Technical Field

[0001] This utility model relates to the field of dustproof power cabinets, and more specifically, to a dustproof power cabinet. Background Technology

[0002] In existing technologies, power cabinets are typically used to install and protect electrical equipment such as switches, circuit breakers, and transformers. However, with the prolonged operation of electrical equipment, a significant amount of heat and dust accumulates inside the power cabinet. If not addressed promptly, this can affect the normal operation and lifespan of the equipment. Therefore, effective heat dissipation and dust prevention have become crucial design considerations for power cabinets.

[0003] Traditional power cabinets typically use natural ventilation or simple filtration devices to solve heat dissipation and dust prevention problems. However, these methods often require cleaning of the filtration devices. Since the power cabinet is responsible for supplying power, it needs to be cleaned during a power outage, which is very inconvenient.

[0004] Although the filter can filter dust, dust will still accumulate on the electrical components inside the power cabinet after a long period of use, so the dust inside the power cabinet needs to be cleaned from time to time. Utility Model Content

[0005] Based on the above-mentioned technical problems, this utility model proposes a dustproof power cabinet.

[0006] A dustproof power cabinet includes: a cabinet body, a cabinet door on the front side of the cabinet body, a heat dissipation vent on the upper part of the cabinet door, an air inlet on the lower rear side of the cabinet body, grooves on the inner wall around the air inlet, a perforated dustproof plate at the air inlet, the edge of the dustproof plate pressing against the grooves, a fixing frame on the outer side of the dustproof plate, evenly spaced grid strips inside the fixing frame, a screw hole on each of the left and right sides of the air inlet, and a side lug on each of the two sides of the fixing frame, each side lug having a locking hole corresponding to the screw hole, and a bolt passing through the locking hole and engaging with the screw hole to lock it in place.

[0007] Preferably, the heat dissipation vent is further provided with a cross-shaped fixing bracket, and the fixing bracket is provided with at least one exhaust fan.

[0008] Preferably, the groove is located at the inner end of the air inlet, and the fixing frame is embedded in the air inlet.

[0009] Preferably, the top of the cabinet is provided with a normally closed top opening, and a high-speed fan is installed at the top opening.

[0010] Beneficial effects:

[0011] 1. The air inlet is equipped with a perforated dustproof plate and evenly spaced grille strips, which can effectively prevent external dust from entering the cabinet. The dustproof plate is designed to be removable for easy replacement.

[0012] 2. The edges of the dustproof plate are pressed against the groove and tightened to the fixed frame with bolts to ensure the stability and sealing of the dustproof plate;

[0013] 3. The front of the power cabinet is equipped with a heat dissipation vent and a built-in cross-shaped fixing bracket and exhaust fan, which can effectively improve the air circulation speed inside the cabinet and accelerate the dissipation of heat. At the same time, when the exhaust fan is turned on, it can also drive out some floating dust.

[0014] 4. The top of the cabinet is equipped with a normally closed top opening, which can be used to install a high-speed fan for forced airflow. The high-speed fan can blow high-speed air to clean the dust inside the power cabinet after a power outage. Attached Figure Description
