Description
Technical Field
[0001] The utility model relates to the field of power distribution cabinet equipment, in particular to an energy-saving and power-saving frequency conversion power distribution cabinet. Background Art
[0002] The inverter control cabinet is a variable frequency speed regulator specially used to control the flow and pressure of fluids such as fans, pumps, and air compressors; it can automatically control the input and output quantity of the water pump group by using the "one control multiple" function of the inverter without the need for a PLC controller; the inverter is equipped with a built-in PID function and a control panel specially designed for constant pressure water supply.
[0003] The existing energy-saving and power-saving variable frequency distribution cabinet needs to ensure that the internal temperature is in a suitable state when in use. In this way, heat is generally dissipated through a fan in conjunction with heat dissipation holes to ensure that the internal temperature is appropriate. However, when used for a long time, dust will be brought in when air enters through the heat dissipation holes. The dust will adhere to the filter net on the outside of the distribution cabinet. If used for a long time, it is easy to cause the filter net holes to be blocked, the filter net ventilation is not smooth, and the normal heat dissipation work is affected. Therefore, a device is urgently needed to solve the above problems. Utility Model Content

When in use, the motor is started, and the motor drives the screw to rotate, so that the movable block drives the cleaning plate to move along the screw. When the cleaning plate passes through the outside of the heat dissipation hole, the outside of the heat dissipation hole is cleaned at this time, thereby ensuring the fluidity of the air, and when the movable block moves downward to the position of contacting the second control switch, the motor turns at this time, so that the movable plate moves upward, and the cleaning is repeated in this way.

When in use, the fan draws out the hot air inside the cabinet and blows it upward, thereby driving the plastic ball to move upward along the net tube. At this time, the connecting rope is in a relaxed state. When the heat dissipation holes are blocked, the air fluidity becomes poor, so that the connecting rope is straightened, and the gravity of the plastic ball pulls the signal switch downward, so that the signal is transmitted to the inside of the control box, thereby controlling the motor to start cleaning, thereby automatically controlling.
