Double-blade vertical-axis wind power generator

Abstract

The invention provides a double-blade vertical-axis wind power generator. The double-blade vertical-axis wind power generator is used for converting wind energy into electric energy. The double-blade vertical-axis wind power generator is characterized in that the double-blade vertical-axis wind power generator comprises a power generator body, a rotary shaft, a plurality of impeller rotary arms and a plurality of blade parts, wherein the power generator body is used for converting mechanical energy into electric energy and provided with a rotor which can rotate; one end of the rotary shaft is fixedly connected with the rotor and drives the rotor to rotate; one end of each impeller rotary arm is fixedly arranged at the other end of the rotary shaft and spaced from the other end of the rotary shaft by a certain angle; the blade parts are in one-to-one correspondence to the impeller rotary arms and are arranged at the other ends of the impeller rotary arms correspondingly; each blade part comprises an inner blade, an outer blade and an adjustment piece; each outer blade is fixedly arranged at the other end of the corresponding impeller rotary arm; each inner blade is movably arranged on the corresponding impeller rotary arm and located on the side, close to the rotary shaft, of the corresponding outer blade; and the adjustment pieces are used for adjusting the positions of the inner blades, so that the distances between the inner blades and the outer blades are adjusted.

Description

technical field [0001] The invention designs a wind power generator, and in particular relates to a double-blade vertical axis wind power generator with high output power. Background technique [0002] With the continuous development of society, people's demand for energy is also increasing year by year. However, the most used fossil energy is gradually facing the problem of shortage. At the same time, because these fossil energy have caused huge pollution to the environment, this makes people Beginning to use more and more renewable energy sources. [0003] Wind energy is a clean renewable energy, and our country has a large amount of wind energy resources, such as Inner Mongolia, Qinghai and other provinces are rich in wind energy resources. Our country also began to use wind energy as early as the last century. There are two types of wind turbines currently in use: horizontal axis wind turbines and vertical axis wind turbines. Compared with horizontal axis wind turbine...

Problems solved by technology

[0004] However, the automatic starting performance of vertical axis wind turbines is poor, because when the wind speed is relatively low, due to the constant blade area, the wind speed at this time cannot start the wind turbine at all, so it is necessary to add a starter motor to realize vertical axis wind power generation machine start

In addition, since the blades of the vertical axis wind turbine are fixed, it can only output the best wind speed at a certain wind speed. However, the wind speed generally changes and cannot be kept within a certain wind speed for a long time. relatively low power
