Vertical axis wind power generation device

Abstract

A vertical axis wind power generation device, including a tower, the tower is connected to the rotating shaft through a fixing piece, the lower part of the rotating shaft is connected to the power generation mechanism, several leaf frames are installed on the rotating shaft, and a corresponding blade frame is installed on each leaf frame , the blade frame is connected with the blade, the first support plate is located at the right end of the leaf frame, the first support plate is hinged with one end of the first connecting rod through a connecting piece, the first fixing seat is installed on the upper frame of the blade frame, and the first fixing seat is installed A first guide rod, a first sliding seat is installed on the first guide rod, a first spring and a second spring are respectively installed on the first guide rod, and the first sliding seat is installed between the first spring and the second spring. It improves the power generation efficiency of the power generation device. It can also avoid damage to the blades at extreme wind speeds when the power generation device encounters strong winds or typhoons, and protects the blades from damage. It also has the advantages of smaller blade rotation angle and high utilization rate of wind energy.

Description

technical field [0001] The invention relates to wind power generation technology, which is a vertical axis wind power generation device. Background technique [0002] Those skilled in the art have made many improvements to the vertical axis wind power generation device in recent years, so that the total power generation of a vertical wind power generation device has reached more than 3000kw, and solved many problems such as the short service life of the wind power generation device and the large amount of maintenance. Insufficient, also solves the deficiency of the blade structure of the wind power generation device at the same time, can also do work and generate electricity under the situation of small wind force. However, after use, it is found that although this power generation device has many advantages, there are still shortcomings: the rotating speed of the blades cannot be controlled. It is also a problem that has been difficult to solve in this field for a long tim...

AI Technical Summary

Problems solved by technology

However, after use, it is found that although this power generation device has many advantages, there are still shortcomings: the rotating speed of the blades cannot be controlled. It is also a problem that has been difficult to solve in this field for a long time; when the blades rotate, collisions between adjacent blades are easy to occur, and the blades are easy to be damaged; collisions occur between the blades and the leaf frames installed by themselves, deforming the blades or leaf frames, and the wind speed The larger the deformation, the more serious the deformation, which will shorten the service life of the blade or leaf frame, etc. The ambient noise is generally 70-80 decibels

Above-mentioned deficiency all also causes the generation efficiency reduction of power generation device simultaneously
