AI Technical Summary

Technical Problem

Traditional wind turbine oil control devices generate metal debris during lubrication, which is difficult to clean regularly, leading to increased wear. Furthermore, inspection and cleaning are challenging, affecting equipment lifespan and efficiency.

Method used

A device comprising a liquid storage component, a liquid inlet component, a liquid outlet component, and a filter component was designed. The filter component achieves online filtration of oil and discharge of impurities through filter holes and an auger structure. Furthermore, the side pipe and sealing cover enable oil sampling inspection without stopping the machine, simplifying the cleaning and sampling process.

Benefits of technology

It enables online filtration and sampling of oil, reducing the difficulty of cleaning and sampling, and improving the service life and working efficiency of the equipment.

Abstract

The utility model provides a wind turbine generator oil regulation and control device, which relates to the technical field of wind turbine generators and comprises a liquid storage part, a cavity is formed on the liquid storage part, a liquid inlet part and a liquid outlet part are fixedly connected onto the liquid storage part, the liquid outlet end of the liquid inlet part is positioned above the liquid inlet end of the liquid outlet part, and the liquid inlet end of the liquid inlet part is fixedly connected with a filter part; the filtering piece comprises a shell part, a first separation cavity and a second separation cavity are formed in the shell part, a plurality of filtering holes are formed in the position, located between the first separation cavity, of the second separation cavity, and an auger is rotationally connected to the interior of the second separation cavity; compared with the prior art, after oil liquid is conveyed into the filter part, the oil liquid is conveyed into the second separation cavity, the oil liquid is filtered through the filter holes, impurities are retained in the second separation cavity, the auger rotates in the second separation cavity, the impurities move along the second separation cavity, and finally the impurities are discharged through the blow-off pipe. And therefore, people can clean impurities in the device without stopping the machine.
