Problems solved by technology

[0003] In the process of using the power generation fan in the past, it is necessary to carry out manual inspection and cleaning on a regular basis to avoid the occurrence of solidified blocks in the internal pitch bearing due to the accumulation of dust and lubricating oil, which affects the pitch motor wheel of the fan during the pitch change process. In addition, in the process of processing the power generation fan, most of them are cleaned manually, which is more troublesome and less efficient

Abstract

The invention discloses variable-pitch bearing cleaning equipment which comprises a fan base, a fan supporting column fixedly installed at the top end of the fan base, a fan rear cover fixedly installed at the top end of the fan supporting column, a pneumatic dust collection device used for conducting the dust collection procedure through wind power and arranged in the fan rear cover, and a reciprocating dust collection device. And an extrusion dust collection device for collecting dust under the driving action of the pneumatic dust suction device is arranged in the fan rear cover. Through wind energy conversion of natural wind power, accompanying dust collection treatment during operation of the bearing end in the rear cover of the fan and the natural release function of the collected dust are achieved, so that the operation stability of the variable-pitch bearing is maintained, and in addition, by means of wind power driving and arrangement of a reciprocating structure, the suspended particles, close to the top end, in the fan rear cover are collected and treated, and the phenomenon that components are short-circuited due to excessive dust in the fan rear cover is avoided.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a cleaning device for variable pitch bearings. Background technique [0002] Wind power generator is to use wind energy to generate electricity. It is a kind of equipment that converts wind energy into mechanical energy and then into electrical energy. As a clean and renewable energy source, wind energy is inexhaustible. Therefore, wind power generation is not only It can supplement the conventional power supply. Since wind energy is also an environmentally friendly energy source, large-scale wind farms have been established in areas with better wind resources, and wind power generation products have also been applied to remote mountain villages and islands. [0003] In the process of using the power generation fan in the past, it is necessary to carry out manual inspection and cleaning on a regular basis to avoid the occurrence of solidified blocks in the internal pitch bearing due...
