Wind driven generator

Abstract

The invention relates to a wind power generation technology. A wind driven generator comprises brake units, a stand column, a case connected with the stand column through a yaw bearing, a power generator located inside the case, and fan blades for driving the power generator to generate power. The yaw bearing is connected with a brake ring. Each brake unit comprises a hydraulic brake and a spring brake, wherein the hydraulic brake comprises a dynamic sealing ring, a brake oil cylinder, a piston, a hydraulic brake part friction plate and a leakage detection mechanism; the spring brake comprises a spring brake part friction plate and a spring; the leakage detection mechanism comprises an annular oil groove, an oil tank and a detection mechanism; and the dynamic sealing ring comprises an inflation sealing ring and an air source. The wind driven generator has the advantages that a rotary shaft of the power generator is good in shock resistance, when a sealing ring fails and leakage occurs, leakage can be found in time, and hydraulic oil is effectively prevented from leaking on the brake ring after leakage is generated, and the problems that when leakage happens to an existing wind driven generator, leakage cannot be found in time and the shock resistance effect of a rotary shaft of the existing wind driven generator is poor are solved.

Description

technical field [0001] The invention relates to wind power generation technology, in particular to a wind power generator. Background technique [0002] A structure of a wind power generator includes a brake unit, a column, a chassis connected to the column through a yaw bearing, a generator located in the chassis, and wind blades that drive the generator to generate electricity. The yaw bearing is connected with a matching mechanism. The brake ring of the moving unit for friction braking. When the wind turbine is in use, the direction of the wind blades is adjusted and fixed through the rotating unit and the brake ring, so that the wind turbine can face the wind accurately. The braking unit of the existing wind power generator is completely provided with hydraulic braking and residual pressure to provide damping torque. When the seal ring fails and causes leakage, it cannot be found in time until it cannot be used. The anti-seismic effect of the rotating shaft of the gene...
