Description

Technical Field

[0001] The present invention relates to the technical field of frequency converters, and in particular to a fan frequency converter. Background Art

[0002] The frequency converter is an electric power control device that applies frequency conversion technology and microelectronics technology to control AC motors by changing the frequency of the motor's working power supply. The frequency converter is widely used in production equipment in various manufacturing fields, such as wire drawing machines, mixers, extruders, slitting machines, winding machines, centrifuges, etc. At present, many frequency converters are not in a separate room. Some frequency converters are directly exposed in the workshop, and some are even directly used in outdoor environments such as grasslands and deserts.

[0003] At present, frequency converters for fans are only protected by an external single-layer chassis and are set up for use in outdoor places. Although the frequency converters for fans have certain waterproof purposes, they are often attacked by wild animals because they are set up outdoors. At this time, the shell is easily damaged. At this time, the waterproof performance of the frequency converter is greatly weakened. When seriously damaged, the frequency converter is very easy to get water and sand into it, causing damage, resulting in serious economic losses. Therefore, a frequency converter for fans is proposed to address the above problems. Summary of the invention

[0013] At present, frequency converters are only protected by an external single-layer chassis. When used in outdoor places, although it has a certain waterproof purpose, since the frequency converter is set outdoors, it is often attacked by wild animals. At this time, the shell is easily damaged. At this time, the waterproof performance of the frequency converter is greatly weakened. When it is seriously damaged, the frequency converter is very easy to get water and sand and cause damage, causing serious economic losses.

At the same time, when the sliding rod is squeezed by the animal, the sliding rod drives the limit ring to squeeze the spring, and the sliding rod squeezes the switch. At this time, the alarm is started, which is used for the purpose of alarming and driving away the wild animals, avoiding the frequency converter from being further damaged, and serving a certain protection purpose.

[0016] As an optional solution of the fan frequency converter described in the present invention, a first solenoid valve is installed on the outer side of the connecting pipe.

[0017] When it is detected that the equipment is damaged by wild animals, the first solenoid valve under the extrusion plate is opened, and the first motor is started to drive the threaded shaft to rotate, the threaded shaft drives the threaded sleeve to move, and the threaded sleeve drives the extrusion plate to move. At this time, the extrusion plate is used to squeeze the expellant airbag of the first solenoid valve opened on the outside of the lower connecting pipe. At this time, the expellant airbag is squeezed, and the expellant inside enters the output pipe, and then enters the dispersion frame, and enters the nozzle through multiple discharge pipes outside the dispersion frame. The expellant is discharged through the inclined nozzle, and the inverter can be sprayed at this time to achieve the purpose of further expelling wild animals, and then the first motor is reset.

[0018] As an optional solution of the fan inverter described in the present invention, the outer side of the threaded sleeve is fixedly connected with a limiting convex plate, and the outer side of the limiting convex plate is slidably connected to the rotating frame.
