Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to an automatic adjustment device for heat dissipation and dust removal in power distribution cabinets. Background Technology

[0002] As the core equipment of the power distribution system, the distribution cabinet faces the dual challenges of heat dissipation and dust prevention during long-term operation. Especially in industrial environments with severe dust pollution, dust accumulation not only affects the heat dissipation efficiency of electrical components inside the cabinet, but may also cause safety hazards such as short circuits and corrosion. Therefore, the automatic adjustment device for heat dissipation and dust removal of the distribution cabinet has become a key technical direction to ensure the stable operation of the equipment. It needs to achieve a dynamic balance between efficient heat dissipation and sealing and dust prevention.

[0003] The current mainstream solution adopts a passive dustproof design, with a dust filter fixedly installed on the outside of the heat dissipation hole. The filter physically intercepts dust, while heat dissipation relies on a temperature-controlled fan for forced ventilation. The fan is triggered to start and stop by a temperature sensor. Some improved designs add multiple layers of filters or removable mesh plates, and the ventilation efficiency is maintained by regular manual cleaning. The overall solution relies on the static filtration capacity of the filter and the active heat dissipation of the fan, which is simple in structure and low in cost.

[0004] However, the above solution has significant drawbacks. When the equipment is shut down, the heat dissipation holes are continuously exposed to the external environment due to the lack of an active sealing mechanism. Dust enters through the open heat dissipation holes and continues to accumulate on the surface of electrical components inside the cabinet. This problem is particularly prominent in high-dust scenarios such as mining and building material processing, causing the dust accumulation rate inside the cabinet to far exceed the filter's interception capacity. This not only exacerbates the degradation of the heat dissipation performance of the components, but may also cause short circuit faults due to the accumulation of conductive dust, seriously threatening the safety of the power distribution system. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic heat dissipation and dust removal adjustment device for power distribution cabinets, which aims to improve the problem of dust easily entering the heat dissipation holes when the equipment is shut down.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic heat dissipation and dust removal adjustment device for a power distribution cabinet, including a housing, a cabinet door rotatably connected to the outer wall of the housing, a connecting frame fixedly connected inside the housing, a sealing component inside the connecting frame, and a dustproof component inside the connecting frame.

[0007] The enclosed assembly includes a dustproof plate, the outer wall of which is slidably connected to the inside of the connecting frame. A connecting block is fixedly connected to the outer wall of the dustproof plate. The outer wall of the connecting block is slidably connected to the inner wall of the connecting frame. A locking rod is slidably connected to the inner wall of the connecting block. A sliding groove plate is fixedly connected to one end of the locking rod. A disc is provided on the outside of the connecting block. A connecting rod is fixedly connected to the outer wall of the disc. The outer wall of the connecting rod is slidably connected to the inner wall of the sliding groove plate. A spring is sleeved on the outer wall of the locking rod. One end of the spring is fixedly connected to the outer wall of the sliding groove plate, and the other end of the spring is fixedly connected to the outer wall of the connecting block.

[0008] Furthermore, the dustproof assembly includes a filter screen, the outer wall of which is slidably connected to the inner wall of the connecting frame, a handle is fixedly connected to one side of the outer wall of the filter screen, a spring plate is slidably connected to the inner wall of the connecting frame, and the spring plate is disposed on the other side of the filter screen.

[0009] Furthermore, a second spring is provided inside the connecting frame, and one end of the second spring is fixedly connected to the outer wall of the spring plate.

[0010] Furthermore, the outer wall of the filter screen is provided with a slot, and the inner wall of the connecting frame is slidably connected with a block, which engages with the slot.

[0011] Furthermore, a spring three is provided inside the connecting frame, and one end of the spring three is fixedly connected to the lower surface of the card block.

[0012] Furthermore, the inner wall of the connecting frame is provided with a groove, the locking rod is engaged with the groove, the outer wall of the disc is fixedly connected with a handle, the outer wall of the housing is provided with a through slot, and the outer wall of the handle is slidably connected to the inside of the slot.

[0013] Furthermore, the outer wall of the housing has multiple heat dissipation holes, the lower side of the interior of the housing has multiple fans, and the outer wall of the cabinet door is fixedly connected with a door lock.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when the power distribution cabinet stops running, the user can drive the disc to rotate by the handle, which will drive the connecting rod to push the connecting block to slide in the connecting frame. The connecting block will drive the dustproof plate to move longitudinally, so that it completely covers the heat dissipation hole channel. The locking rod is embedded in the groove under the action of the spring to lock the position, ensuring that the dustproof plate is tightly closed. This manual locking mechanism completely isolates the intrusion of external dust when the equipment is idle, effectively protects the electrical components in the cabinet, and is simple to operate and has reliable sealing.

[0017] 2. In this utility model, when cleaning is required, the user can directly pull the filter handle to disengage the locking block from the slot. The filter automatically pops out of the connecting frame under the elastic force of the spring plate and spring, achieving quick disassembly. When installing in reverse, the filter is pushed into the guide groove of the connecting frame, and the locking block is automatically embedded into the slot and locked by the pressure of the spring. The spring plate provides continuous clamping force to ensure the fit of the filter. This design simplifies the filter disassembly and assembly process, improves daily dust removal efficiency, and ensures long-term dustproof stability. Attached Figure Description
