Background

With the progress of science and technology and the development of society, the wind power generation in China is rapidly developed, and the rapid development of a vertical axis wind power generator follows. Wind energy is increasingly gaining attention as a clean renewable energy source. Wind has long been used mainly by windmills to pump water, mill surfaces, etc., and there is now interest in how to use wind to generate electricity. The kinetic energy of wind is converted into mechanical kinetic energy, and then the mechanical energy is converted into electric kinetic energy, namely wind power generation. The principle of wind power generation is that wind power drives windmill blades to rotate, and then the rotating speed is increased through a speed increaser, so that a generator is promoted to generate electricity. Since wind power generation does not require the use of fuel and does not generate radiation or air pollution, wind power generation is forming a hot tide in the world.

In the existing vertical axis wind power generation system, wind power is mainly obtained by blades, and the principle is as follows: the wind strikes from the blade front, and the blade obtains the lateral pressure of wind and makes the blade drive the wind wheel and rotate, however, the deep bead of a lot of blades is fixed setting at present, can not be according to wind direction adjustment direction, does not possess the function of leaking out the wind, can not make full use of wind energy, has great limitation.

Compared with the prior art, the utility model provides a deep bead of vertical axis aerogenerator blade possesses following beneficial effect:

1. the utility model has the advantages that the baffle is arranged at the right port of the wind scoop, the baffle is semicircular, the vertical end surface at the outer side of the baffle is hinged with the upper end part and the lower end part of the wind scoop through the hinge, the limit block matched with the baffle is arranged at the inner side of the right port of the wind scoop, the wind scoop at the left side of the hinge is vertically provided with the rotating shaft in a penetrating way, the support rod is fixedly arranged between the upper inner surface and the lower inner surface of the wind scoop at the left side of the rotating shaft, when in use, the baffle can be blown outwards when the front side of the wind scoop is stressed, namely, is in a wind-exposed state, so that the baffle rotates outwards around the hinge and reaches the limit block to stop, and is in a closed state, the baffle and the wind scoop are in ninety-degree included angle, the wind scoop receives wind to the maximum extent, the blades do work, the blades are converted into kinetic, the baffle and the wind scoop form a zero-degree included angle, so that the wind is reduced, and no work is done.

2. The utility model discloses a pivot be eccentric mounting, locate the right side of intermediate position about the wind scoop, during the use, the benefit of pivot eccentric mounting lies in, when the wind scoop receives the wind, the wind scoop can be because of the uneven rotation of pivot both sides atress.

3. The utility model discloses a hinge and pivot between distance be less than the radius of baffle, during the use, the effect of this structure lies in, when the baffle is in open mode (baffle and wind scoop are zero degree contained angle), the pivot can play limiting displacement to the baffle, prevents to rotate to the wind scoop outside.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 4, a wind deflector for a vertical axis wind turbine blade comprises a wind scoop 1, wherein the wind scoop 1 is integrally in a semi-cylindrical shape with two transverse ends and an opening at the front end, a baffle 2 is arranged at the right end opening of the wind scoop 1, the baffle 2 is in a semi-circular shape, the cambered surface is matched with the contour of the inner surface of the wind scoop 1, the vertical end surface at the outer side of the baffle 2 is hinged with the upper end part and the lower end part of the wind scoop 1 through a hinge 21, a limiting block 11 matched with the baffle 2 is arranged at the inner side of the right end opening of the wind scoop 1, a rotating shaft 3 is vertically arranged on the wind scoop 1 at the left side of the hinge 21 in a penetrating manner (the upper end part and the lower end part are arranged on a blade frame (not shown in the figure), and a support rod.

In the above embodiment, specifically, the rotating shaft 3 is eccentrically installed and is disposed on the right side of the left and right middle positions of the wind scoop 1.

In the above embodiment, specifically, when the baffle 2 contacts the limiting block 11, the baffle 2 and the wind scoop 1 are in a vertical closed state.

In the above embodiment, specifically, the distance between the hinge 21 and the rotating shaft 3 is smaller than the radius of the baffle 2.

In the above embodiment, more specifically, in this embodiment, the number of the limiting blocks 11 is three, and the limiting blocks are respectively in a rectangular shape and circumferentially and uniformly distributed on the inner surface of the wind scoop 1 at intervals or continuously.

In the above embodiment, more specifically, in the present embodiment, the number of the supporting rods 4 is 2, and the supporting rods are distributed at intervals from left to right.

The working principle is as follows: when 1 front side atress of wind scoop, be in when the state of catching wind promptly, can blow baffle 2 to the outside, make baffle 2 rotate outwards around hinge 21, reach stopper 11 department and stop, for closed state, baffle 2 is ninety degrees contained angle with wind scoop 1, wind scoop 1 at utmost pocket receives the wind this moment, the blade does work, convert it into kinetic energy, play the effect of make full use of wind energy, along with the blade rotates, wind scoop 1 angle also takes place thereupon and rotates, when being in the state of letting out the wind, baffle 2 freely catches the wind and is in the open mode, baffle 2 is zero degree contained angle with wind scoop 1, reduce and catch the wind, do not do the work. Specifically, the rotating shaft 3 is eccentrically installed, which is beneficial in that when the wind scoop 1 is subjected to wind, the wind scoop 1 can rotate due to uneven stress on both sides of the rotating shaft 3. When baffle 2 was in the open mode (baffle 2 was zero degree contained angle with wind scoop 1), pivot 3 can play limiting displacement to baffle 2, prevented to rotate to the wind scoop 1 outside.

The components used in the present invention are all common standard components or components known to those skilled in the art, and the structure and principle thereof are well known to those skilled in the art.
