Description

Technical Field

[0001] This application relates to the field of power distribution cabinets, and more particularly to a dustproof power distribution cabinet. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), metering cabinets (boxes), etc., and are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers, and are used in situations where the load is relatively dispersed and there are few circuits.

[0003] Power distribution cabinets and other power supply equipment are prone to accumulating dust, which can affect the working condition of electronic components inside. When there is a lot of dust inside the distribution cabinet, it can easily form charged particles, which then absorb moisture from the air. Over time, the insulation of exposed primary and secondary wires or joints of some components may deteriorate, leading to faults such as short circuits and grounding. Furthermore, electrical components, especially some precision electronic control equipment, have certain environmental requirements, and excessive dust accumulation can even cause components to burn out. Summary of the Invention

[0004] To effectively prevent dust from entering the inside of the distribution cabinet, this application provides a dustproof distribution cabinet.

[0005] The dustproof power distribution cabinet provided in this application adopts the following technical solution:

[0006] A dustproof power distribution cabinet includes a cabinet body, an eaves roof disposed on the top of the cabinet body, and a base disposed at the bottom of the cabinet body. Multiple elongated ventilation holes are evenly arranged on one of the two side walls of the cabinet body along its height direction. Rotary rollers are rotatably connected to the ventilation holes, and dust-adhesive tubes are sleeved on the rotary rollers. A drive mechanism for driving the multiple rotary rollers to rotate synchronously is provided on the cabinet body.

[0007] By adopting the above technical solution, when outside air enters the cabinet through the vent, the rotating rollers adhere dust from the air to the dust-adhesive rollers, effectively preventing dust from entering the dust collection cabinet. By installing a distribution cabinet that can adhere and remove dust from outside air entering the cabinet, dust entry into the cabinet is effectively prevented, ensuring the dustproof effect of the distribution cabinet and thus effectively guaranteeing the normal operation of the electrical components inside the distribution cabinet.

[0008] Optionally, the drive mechanism includes a drive shaft and a drive motor. A drive cavity is provided on the side wall of the cabinet along its height direction, located outside one end of the vent hole. The drive shaft is vertically disposed in the drive cavity and rotatably connected to it. One end of the rotating roller shaft extends into the drive cavity and is provided with a first bevel gear. Multiple second bevel gears are evenly disposed on the drive shaft along its length direction, and the multiple second bevel gears mesh with multiple first bevel gears in sequence. The drive motor is horizontally disposed on the base and connected to the drive shaft through a reduction assembly.

[0009] By adopting the above technical solution and setting a simple and stable drive mechanism, the stable drive of multiple rotating rollers is achieved, thereby ensuring the adhesion effect of the dust-adhesive roller on the dust and thus ensuring the dustproof effect of the power distribution cabinet.

[0010] Optionally, the reduction assembly includes a driving bevel gear and a driven bevel gear. The driving bevel gear is disposed on the drive motor and located in the drive cavity. The driven bevel gear is disposed at the bottom end of the drive shaft and meshes with the driving bevel gear for transmission. The diameter of the driving bevel gear is smaller than the diameter of the driven bevel gear.

[0011] By adopting the above technical solution and setting a simple and stable deceleration component, the deceleration motion of the drive shaft is realized, which in turn realizes the deceleration rotation of the roller, ensuring the adhesion effect of the dust sticking cylinder to the dust, and thus ensuring the dustproof effect of the distribution box.

[0012] Optionally, the diameter of the second bevel gear is smaller than the diameter of the first bevel gear.

[0013] By adopting the above technical solution, the rotation of the roller is reduced in speed by setting a second gear with a smaller diameter to drive a first gear with a larger diameter. With the use of the speed reduction component, the low-speed rotation of the roller is further guaranteed, ensuring the contact time between the dust sticking tube and the dust, further ensuring the adhesion effect of the dust sticking tube to the dust, and thus further ensuring the dustproof effect of the distribution box.

[0014] Optionally, the adhesive tube includes a cylinder sleeved on the rotating roller and a sticker wrapped around the outside of the cylinder. The cylinder and the rotating roller are detachably connected. The side wall of the cabinet is provided with an installation cavity communicating with a plurality of ventilation holes along its height direction. A support plate for abutting its end is vertically embedded in the installation cavity. The support plate can slide horizontally along the installation cavity.

A cover plate for sealing the installation cavity is also embedded in the installation cavity. Abutting plates for abutting the support plate are provided at the lower end and the upper end of the cover plate. A locking component for locking the cover plate is provided on the cabinet.

[0015] By adopting the above technical solution, when replacing the ash-adhesive cartridge, first open the cover plate, then slide the support plate outward to detach it from the rotating roller shaft. At this point, the old ash-adhesive cartridge can be removed and the new one installed on the rotating roller. Next, re-embed the support plate into the mounting cavity and insert the rotating roller shaft into the support hole. Finally, install the cover plate to complete the replacement of the ash-adhesive cartridge. By setting up an detachable ash-adhesive cartridge and a detachable cover assembly, convenient replacement of the ash-adhesive cartridge is achieved, thereby effectively improving the service life of the distribution cabinet.

[0016] Optionally, the locking assembly includes multiple locking bolts, the cabinet body is provided with an auxiliary groove communicating with the mounting cavity along the circumferential direction of the mounting cavity, and the cover plate is provided with an auxiliary plate for embedding in the auxiliary groove along its circumferential direction. The cover plate auxiliary plate is provided with multiple locking holes evenly arranged along its circumferential direction, the bottom of the auxiliary groove is provided with a locking groove communicating with the locking holes, and the locking bolt passes through the locking holes and the locking groove and is threadedly connected to the locking groove.

[0017] By adopting the above technical solution and setting a simple and stable locking mechanism, a stable connection between the cover plate and the cabinet is achieved, thereby effectively ensuring the connection stability between the roller shaft and the support plate.

[0018] Optionally, a sealing gasket is provided on the inner side of the support plate to abut against the end of the mounting cavity.

[0019] By adopting the above technical solution and setting a sealing gasket, the tightness of the connection between the support plate and the end of the mounting cavity is ensured, effectively preventing air from entering the mounting cavity, and thus effectively preventing dust from entering the mounting cavity.

[0020] Optionally, both sides of the support plate are provided with operating holes along their height direction.

[0021] By adopting the above technical solution and setting up the operation hole, it is convenient for the staff to adjust the angle of the rotating roller shaft, and thus convenient for the staff to insert the rotating roller shaft into the support hole.

[0022] Optionally, a dustproof net is provided on the inside of the cabinet to cover the ventilation holes.

[0023] By adopting the above technical solution, the air entering the cabinet is further filtered by setting up a dustproof net, and the dust removal effect of the power distribution cabinet is further guaranteed by the use of the dust collection tube.

[0024] Optionally, a pair of exhaust holes for connecting the inside and outside of the cabinet are provided inside the eaves. The exhaust holes are arranged in a zigzag shape, and a fan for drawing air from inside the cabinet to the outside is embedded in the exhaust holes.

[0025] By adopting the above technical solution, and by setting up air extraction holes and fans, it is helpful to accelerate the circulation of air inside and outside the cabinet, and ensure the overall heat dissipation effect of the power distribution cabinet. At the same time, setting the air extraction holes in a zigzag shape effectively prevents external dust from entering the cabinet through the air extraction holes.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting up a power distribution cabinet that can remove dust from the air entering the cabinet from the outside, dust is effectively prevented from entering the cabinet, ensuring the dustproof effect of the power distribution cabinet and thus ensuring the normal operation of the electrical components inside the power distribution cabinet.
