Problems solved by technology

[0003] Horizontal wind turbines are known to the general public, but many experiments and studies have shown that under the condition of equal wind receiving area of ​​the wind rotors, the wind energy utilization rate, starting performance, noise performance, fatigue life and applicable field of vertical wind rotors , assembly and maintenance, etc. are better than horizontal wind turbines, but today's vertical axis wind turbine blades and wind shafts adopt a parallel connection method, that is to say, more than two metal The poles are connected by horizontal lines, resulting in the fact that the wind shaft is almost as long as the wind blades, and the longer the wind shaft, the greater the self-weight, and the greater the consumption of wind energy in the process of converting into mechanical energy, which affects the power generation efficiency. If the shaft is too long, the greater the torque generated by the wind shaft during operation, it will affect the service life of the wind shaft, and even cause the wind shaft to break. One of the important means to improve the power generation efficiency of vertical axis wind turbines and prolong the service life of generators

Abstract

The invention discloses a vertical-axis wind turbine blade and a structure thereof. The vertical-axis wind turbine blade comprises ceramic aluminum alloy supports rotationally connected with the upperend of a wind shaft. Each ceramic aluminum alloy support comprises multiple supporting frames and a first side support, each first side support is connected with four transverse supports, and the multiple transverse supports of each first side support are connected with a second side support together. The transverse supports are evenly distributed on the first side supports and the second side supports, the transverse supports are connected with impeller components through screws, each impeller component comprises a ceramic aluminum alloy arc-shaped wind deflector, each ceramic aluminum alloyarc-shaped wind deflector is connected with four connecting plates, the connecting plates are provided with rectangular avoiding openings, and the positions and sizes of the rectangular avoiding openings are matched with those of the second side supports. The four connecting plates of each impeller component are connected with the corresponding transverse supports through screws, the connecting plates are connected with lug plates, the lug plates and the transverse supports are provided with through holes, and the two through holes of each lug plate and the corresponding transverse support are matched with locking screws and are connected with reinforcing strips through the locking screws.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to a vertical axis wind power generator blade and its structure. Background technique [0002] With the development and progress of science and technology, people's requirements for things have changed from the old thinking that can be used to become quite delicate and demanding. Only the idea of ​​continuous improvement or innovation will produce new forms to increase the added value of products. , in order to survive under the test of fierce market competition. As a clean and renewable energy, wind energy has been paid more and more attention by people. Wind has been used by people for a long time, mainly through windmills to pump water and grind flour, but now people are interested in how to use wind to generate electricity. Simply put, wind power generation is to turn the wind wheel through wind energy, convert the wind energy into mechanical energy, ...
