Centrifugal force constant speed wind turbine

Abstract

The invention relates to a centrifugal force constant speed wind power generator, which includes a fan blade assembly and a generator, and is characterized in that: in the fan blade assembly, the chassis is fixedly installed on the input shaft, and at least two installations uniformly distributed in the circumferential direction are arranged in the chassis. cavity, the blade shaft support is installed in the radial chamber of the installation cavity, the blade shaft bevel gear is provided at the inner end of the blade shaft, and the blade is fixedly installed on the blade shaft; the support shaft of the centrifugal block is installed in the axial direction of the installation cavity In the chamber, the centrifugal block bevel gear is arranged at the inner end of the centrifugal block support shaft, and the centrifugal block bevel gear meshes with the blade shaft bevel gear; One end is connected, and the other end of the tension spring is connected to the chassis; each fan blade is provided with a blade windward angle positioning column that limits the extreme position of the windward angle of the blade. The invention can make the windward angle of the fan blades change with the change of the wind force, keep the rotating speed of the fan blades constant within the set rotating speed range, and ensure voltage stability.

Description

technical field [0001] The invention relates to a wind power generating equipment, in particular to a centrifugal force constant speed wind power generator, which belongs to the technical field of wind energy utilization. Background technique [0002] A wind turbine is a device that converts wind energy into electrical energy, and is mainly composed of blades, generators, mechanical components and electrical components. According to the different rotation axes, wind turbines are mainly divided into two types: horizontal axis wind turbines and vertical axis wind turbines. At present, horizontal axis wind turbines occupy the mainstream position in the market. [0003] Due to the influence of the geographical environment, the wind power generators in the prior art will cause the force acting on the wind blades to change accordingly, so that the speed cannot be kept constant within the set speed range, resulting in unstable voltage and difficult to directly connect to the grid. ...

Problems solved by technology

[0003] Due to the influence of the geographical environment, the wind power generators in the prior art will cause the force acting on the wind blades to change accordingly, so that the speed cannot be kept constant within the set speed range, resulting in unstable voltage and difficulty in directly connecting to the grid

Therefore, a constant speed device is required. The traditional constant speed device adopts the friction constant speed method. The damage rate of the constant speed device with this structure is high, resulting in a short service life of the equipment.
