[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The low-noise and environment-friendly low-voltage power distribution cabinet uses a protective mechanism. The protective component uses a protective top plate to prevent foreign objects from falling on the cabinet body. The damping property of the first damper itself and the action force of the first spring reduce the impact force on the protective top plate, thereby reducing the vibration of the cabinet body. The cleaning component uses the first slider to drive the first connecting plate to move, so that the first cleaning brush moves. The first cleaning brush drives the foreign objects on the protective top plate to slide, thereby cleaning up the foreign objects dropped on the protective top plate, avoiding greater pressure on the cabinet body and improving the stability of the low-voltage power distribution cabinet.

[0015] 2. The low-noise and environment-friendly low-voltage power distribution cabinet uses a heat dissipation mechanism and an air pump to extract the gas inside the cabinet, so that the external air enters the cabinet after being filtered by the filter plate, thereby increasing the air flow in the cabinet and reducing the temperature in the cabinet. The moisture-proof agent in the placement box absorbs the moisture contained in the air entering the cabinet to prevent the components in the cabinet from being damaged by moisture. At the same time, the flowing air drives the fan blades to rotate, so that the first rotating rod and the second rotating rod rotate, and the second rotating rod drives the second cleaning brush to rotate to clean the surface of the filter plate to prevent dust and impurities from clogging the filter plate, thereby improving the heat dissipation effect of the low-voltage power distribution cabinet.

[0016] 3. This low-noise, environmentally friendly low-voltage distribution cabinet has a sealing mechanism and a sealing ring to increase the cabinet door. The sealing effect between the cabinet door and the cabinet body can reduce the entry of dust and moisture into the cabinet body. At the same time, the extrusion between the clamping ring and the positioning ball can be used to increase the sealing effect of the sealing ring. The positioning ball and the clamping ring can reduce the impact between the cabinet door and the cabinet body when the cabinet door is closed, reduce the noise generated, and avoid damage to the cabinet door due to impact.

[0017] 4. The low-noise and environment-friendly low-voltage power distribution cabinet, through the shock-absorbing mechanism, utilizes the damping property of the second damper itself and the force of the third spring to achieve a shock-absorbing effect when the cabinet is subjected to severe vibration. The noise reduction airbag also achieves a shock-absorbing effect when the cabinet is subjected to slight vibration, thereby preventing the third spring from being damaged due to long-term extrusion, and improving the shock-absorbing effect of the low-voltage power distribution cabinet.

[0018] 5. The low-noise and environmentally friendly low-voltage distribution cabinet absorbs the noise inside the connection frame through sound-absorbing cotton, and at the same time the shock-absorbing mechanism reduces the noise generated by the vibration of the cabinet, thereby reducing the noise generated by the cabinet, avoiding the impact of noise on the surrounding environment, and improving the noise reduction effect of the low-voltage distribution cabinet.
