A vertical axis wind power generator

Abstract

The invention relates to a vertical axis wind power generation device. The vertical axis wind power generation device comprises a tower support, the tower support is connected with a rotating shaft through a fixing piece, the lower portion of the rotating shaft is connected with a power generation mechanism, a plurality of blade frames are installed on the rotating shaft, each blade frame is provided with a corresponding vane frame, and each vane frame is connected with a blade; a first supporting plate is located at the right end of each blade frame and hinged to one end of a first connecting rod through a connecting piece, a first fixing base is installed on an upper border of each blade frame, a first guide rod is installed on each first fixing base, and a first sliding base is installed on each first guide rod; and a first spring and a second spring are installed on each first guide rod, and each first sliding base is installed between the corresponding first spring and the corresponding second spring. By means of the vertical axis wind power generation device, the generating efficiency of the power generation device is improved, and damage, generated when the power generation device suffers from gale or typhoon, to the blades at a top air speed can be avoided, and the blades are prevented from being damaged. The vertical axis wind power generation device further has the beneficial effects of being small in blade rotating angle, high in wind energy using rate and the like.

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...

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
