Gyroscope type wind power generation device with upper generator and lower generator

Abstract

The gyro type wind power generation device comprises a supporting column fixedly arranged on the ground, the lower generator is fixed to the top of the supporting column through a supporting plate, a high-strength wear-resisting bearing steel block is fixed to a bottom plate of a machine shell of the lower generator, a rotating shaft extends out of the top of the lower generator, and the lower section of the rotating shaft is connected with a lower generator rotor. A high-strength wear-resistant bearing steel ball which is in smooth contact with the top face of the high-strength wear-resistant bearing steel block and can rotate is embedded in the conical bottom of the rotating shaft, a stabilizing body is arranged above the top end of the rotating shaft in advance and fixedly connected with the upper generator through a machine shell connecting rod piece, and the upper section of the rotating shaft is fixed to an upper generator rotor. Cylindrical steel ball bearings are arranged at the centers of top and bottom plates of machine shells of the upper generator and the lower generator and connected with a rotating shaft, the middle section of the rotating shaft is fixedly connected with a circular gyroscope rotating cake which is gradually thinned from the center to the edge, and the periphery of the gyroscope rotating cake is connected with clamshell-shaped blades through four connecting pieces. The wind power generation mode is ingeniously and reasonably optimized, and the power generation efficiency is fully improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a gyro-type wind power generation device with upper and lower double generators. Background technique [0002] A wind turbine is a power generation device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. However, the inventors of the present application have found through research that in the existing gyro-type wind power generator structure, only one generator is concentratedly installed under the gyro rotating cake, and the resulting sinking of the center of gravity of the gyro will greatly affect the rotation of the gyro. The precession of the cake rotation and the balance of the fixed axis will be affected, thereby reducing the power generation efficiency and increasing the unit power generation cost; at the same time, in the existing gyro-type wind turbine structure, a tapered roller bear...

AI Technical Summary

Problems solved by technology

[0003] In view of the existing gyro-type wind turbine structure, only one generator is installed under the gyro cake, which leads to the sinking of the center of gravity of the gyro rotation, which will affect the precession and fixed axis balance of the gyro rotation This will reduce the power generation efficiency and increase the unit power generation cost. At the same time, the tapered roller bearing is used to bear the vertical load of the rotating body, so the generated frictional resistance is relatively large, so the speed is low and durable under the same wind force The performance is poor, and the obtained electric energy is relatively less. The present invention provides a gyro-type wind power generation device with upper and lower double generators.
