Problems solved by technology

[0003] Existing wind power generators will generate a lot of heat due to friction during work, which will increase the temperature inside the existing wind power generators, but the existing wind power generators generally use permanent magnet direct drive generators, and permanent magnet direct drive The permanent magnet in the generator is easy to demagnetize when exposed to high temperature. Not only that, the slip ring of the existing wind generator is responsible for the power of the entire system in the wind power generation system, and the control signal and data transmission functions are very critical in the entire fan system. The precision, reliability and working life of the components directly affect the performance of the wind power generation system, but because the existing wind power generators are not completely sealed, dust and water vapor are easily mixed into the slip ring, which changes the mechanical properties of the slip ring

Abstract

The invention relates to an aerogenerator having cooling and slip ring dustproof functions. The aerogenerator comprises a superhot column, a main body, a wheel hub and three fan blades. The interior of the main body is equipped with an electricity-generating mechanism, a heat radiation mechanism and an air extraction mechanism. The electricity-generating mechanism comprises a rotary shaft, a sliding ring and an aerogenerator housing. The heat radiation mechanism comprises an air outlet pipe, an air outlet pipe and multiple heat absorption units. The heat absorption units comprise heat absorption boards, heat absorption pipes and multiple fixing assemblies. The air extraction mechanism comprises a driving unit and an air inlet unit. The air inlet unit comprises a dust-proof cover, a ventilating pipe and an exhaust pipe. By the heat radiation mechanism, a great quantity of heat caused by friction during operation of the aerogenerator is dispersed to the air, thereby avoiding demagnetization of a permanent magnet in the aerogenerator in case of high temperature. Furthermore, through the air extraction mechanism, the aerogenerator can prevent dust and steam from being mixed into the sliding ring. Accordingly, changes in a mechanical property of the sliding ring are avoided.

Description

technical field [0001] The invention relates to the field of wind power generation equipment, in particular to a wind power generator with cooling and slip ring dustproof functions. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. A wind turbine generally consists of a wind wheel, a power generation device, a steering device, a tower, a speed limiting safety mechanism, and an energy storage device. components such as. [0003] Existing wind power generators will generate a lot of heat due to friction during work, which will increase the temperature inside the existing wind power generators, but the existing wind power generators generally use permanent magnet direct drive generators, and permanent magnet direct drive The permanent magnet in the generator is easy to demagnetize when exposed to high temperature. Not only that, the slip ring ...
