Description

Technical Field

[0001] The utility model relates to the technical field of frequency converters, in particular to an industrial frequency converter. Background Art

[0002] The frequency converter is an electric power control device that uses frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply.

[0003] For example, the authorization announcement number CN215498707U is an industrial frequency converter with good heat dissipation. The above document can clean the dust on the surface of the dust net to prevent clogging through the motor, the first screw and the cleaning brush. The preferred driving motor can drive the first bevel gear and the second bevel gear to mesh and rotate when the shaft rotates, and then the first screw is rotated, so that the threaded block moves on the surface of the first screw. Due to the limitation of the slider and the slide rail, the threaded block can only move in a straight line, so that the cleaning brush cleans the surface of the dust net. However, the industrial frequency converter in the above document is usually fixed by the rear connecting ear and the bolt during use. When the industrial frequency converter is repaired, the number of bolts used is large and the number of turns of each bolt is large, which makes the disassembly operation of the industrial frequency converter more cumbersome. At the same time, after the maintenance is completed, when the industrial frequency converter needs to be installed in the original position, the bolt needs to be repeatedly turned to fix the industrial frequency converter, so it is not convenient to repair the industrial frequency converter.
