[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits; the motor control center is used in occasions with concentrated loads and more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] When the distribution cabinet is working, a certain amount of heat will be generated. High heat will damage the electrical components inside the distribution cabinet. Ventilation holes will be opened on both sides of the distribution cabinet to facilitate heat dissipation inside the distribution cabinet.

[0004] However, after the distribution cabinet has been installed and used for a period of time, dust will accumulate in the ventilation holes of the distribution cabinet, which will affect the heat dissipation effect of the distribution cabinet and easily cause damage to the electrical components inside the distribution cabinet. Utility Model Content

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. The utility model provides components such as a threaded rod, a threaded block, and a brush. The rotation of the threaded rod can drive the gear to rotate, and the toothed belt meshing therewith can drive another gear to rotate, thereby achieving the effect of the two threaded rods rotating. The rotation of the threaded rod drives the threaded block to move, and then the threaded block drives the brush to move.

The baffle reaches the heat dissipation hole before the brush. When the brush cleans the dust on the surface of the heat dissipation hole, the baffle can prevent the cleaned dust from entering the interior of the cabinet, thereby maintaining the cleanliness of the interior of the cabinet.
