Problems solved by technology
[0006] The purpose of the present invention is to provide an intelligent vector control frequency converter to solve the above-mentioned problem in the background technology that when cleaning the dust on the filter screen, the filter screen needs to be removed for cleaning. During the cleaning process, the filter screen may be damaged due to collisions. As for the problem of frequent cleaning of the filter screen when it cannot be used continuously and the air pollution is serious

Embodiment approach
[0055] As an embodiment of the present invention, refer to image 3 The dust-proof mechanism includes a third sleeve 31 fixedly installed in the dust box 11 and communicated with the second sleeve 25 , and a first inserting rod 32 and a second inserting rod 33 are movably arranged in the third sleeve 31 .
[0056] When the worker pushes up the drain pipe 28 to start draining water, the drainage drives the second piston plate 26 to move up along the second sleeve 25, and the pressure in the cavity above the second piston plate 26 in the second sleeve 25 increases, Since the third sleeve 31 communicates with the second sleeve 25, the pressure in the third sleeve 31 also increases, and at this moment, under the action of the pressure, the first insertion rod 32 and the second insertion rod 33 are both released from the third Sleeve 31 protrudes and enters the first conduit 13 and the second conduit 18 respectively to block them, which can prevent the dust in the box 1 from contin...

The invention relates to the technical field of frequency converters, in particular to an intelligent vector control frequency converter which comprises a box body, a heat dissipation opening is formed in the top wall of the box body, a double-end motor is fixedly installed on the inner bottom wall of the box body, a rotating rod is vertically and fixedly installed at the first output end of the double-end motor, and a fan is fixedly installed on the rotating rod. A first sleeve is fixedly mounted on the inner wall of the box body, a mounting plate is horizontally and fixedly mounted in the first sleeve, and a sliding groove is formed in the top wall of the mounting plate. The support installed on the rotating rod is driven by the double-end motor to rotate, so that the filter screen is driven to rotate in the rotating process of the support, dust attached to the surface of the filter screen can be separated from the filter screen under the action of centrifugal force, the filter screen can be cleaned in time, the filter screen is kept clean at any time, and the heat dissipation effect is ensured.
Description
technical field [0001] The invention relates to the technical field of frequency converters, in particular to an intelligent vector control frequency converter. Background technique [0002] With the continuous development and improvement of people's scientific and technological level, people have made outstanding achievements in various technologies, among which frequency converter is an essential tool commonly used in people's life and production, and intelligent vector control frequency converter has gradually replaced the common inverter. [0003] After retrieval, Chinese Patent No. CN209823632U discloses an intelligent vector control frequency converter, which includes: a housing, a dehumidification structure, a bearing frame, a partition and a fan, and a fan is installed at the bottom of the housing, and Both sides of the fan are equipped with dehumidification structures, the inside of the shell is welded with a partition, and the top of the partition is provided with...
