Abstract

The invention relates to a vertical shaft type wind turbine with retractable blades, which is characterized in that each blade of the wind turbine is connected through a foldable wind-catching plate, and the blades can realize extension of half of a rotating cycle and contraction of the other half of the rotating cycle under the wind effect, thereby producing unbalanced wind resistance on the two sides of the wind turbine so as to generate rotation and to drive the machine to operate. Since the blades have large areas for wind interruption in the design, the wind turbine can obtain more wind energy and has high practical value.

Description

Vertical shaft type wind turbine with retractable blade

Technical field

A kind of vertical shaft type wind turbine with retractable blade.Its major character is: each blade in the wind wheel is all connected by the folding plate that goes for a drive, this blade can realize that under the effect of external force half revolution stretches half revolution and tightens, and causes the uneven horizontal of wind wheel both sides windage and rotates and drive machine works with this.This design is because wind wheel blade cut-off wind area is big, and the wind energy of acquisition is many, so have higher utility.

Background technique

Present wind-power electricity generation mainly is three pages of horizontal type generators, owing to will utilize the major diameter fan could obtain high energy electric power, so the building of lifting fan and motor will be built promptly very firm very highly again, cost of electricity-generating is increased considerably.And other existing wind-power electricity generation modes are because the cut-off wind area of fan is little, wind energy utilization is low, and can't obtain high energy electric power.

Summary of the invention

At above-mentioned situation, the present inventor has worked out the retractable wind wheel of this blade.

Concrete summary of the invention is as follows:

1, the blade on the wind wheel all is to be connected by a plurality of folding plates that go for a drive, and makes blade can realize stretching and shrinking under the effect of external force;

2, retractable blade one side is fixed on the wind wheel outer rim, opposite side is installed and can be drawn the flexible towing plate of blade by wind-force, its concrete working principle is: when contraction-like blade rotates to the forefront of wind wheel windward side, under the promotion of wind-force, the blade that towing plate promptly hauls contraction prolongs the wind wheel central direction rapidly and stretches, the blade that makes expansion after revolve in a large amount of wind energies of intercepting and capturing; And when the blade that launches rotates to rear, wind wheel windward side, towing plate pushes away the blade that launches again and has been reduced on the wind wheel limit, the blade that shrinks this moment launches the power of blade by other, to revolve before the minimum cut-off wind area, forward the forefront of wind wheel windward side next time in minimum windage, begin the running of next circumference;

3, the width after pressing blade and tightening, the semicircle draught-proofing channel of dashing forward before outer rim is installed is protected when revolving before the fan blade that tightens with this and not to be opened by wind;

4, at fan blade towing plate rear, be provided with the flexible retaining that to control the blade collapsing length, it is realized with restriction towing plate move distance, its effect is the rotation dynamics of regulating wind wheel with the variation of blade cut-off wind area, can control generated energy with this, flexible in case of necessity retaining can stop using or the defence violent typhoon wind wheel the mandatory semicircle draught-proofing channel that pushes of blade.

Description of drawings

Fig. 1 is a plan structure schematic representation of the present invention.

Among the figure: 1, wind direction, 2 wind wheel sense of rotation, 3, the fan blade towing plate, 4, the fan blade that stretching, 5, the fan blade that launches fully, 6, the fan blade that shrinking, 7, the fan blade that shrinks fully, 8, the semicircle draught-proofing channel, 9, flexible retaining.

Embodiment

The plan plan is made three combined type wind wheels and is described below in conjunction with the accompanying drawings:

1, make long 3M with corner bracket, 120 of the edges of boards frames of going for a drive of wide 0.5M, the equal size of cutting, good toughness, corrosion-resistant, 120 of airtight linings are tightened lining and are fixed on the edges of boards frame that goes for a drive, and the single plate that goes for a drive is promptly made;

2, per 10 of the plate that goes for a drive that will make with loose-leaf is one group and connects, and forms 12 telescopic wind wheel blades;

3, make 3 of the vertical wind wheel frameworks of quaterfoil that diameter 10M, the high 3.2M center of circle have a skin, make three on high 4M, diameter 0.2M wind wheel vertical shaft, three wind wheel vertical shafts are respectively installed on three wind wheel frameworks;

4, three vertical shaft tops are connected to each other with angle steel and fix, its lower end is also used with quadrat method and is carried out firmly;

5, wind wheel blade one side is fixed on the wind wheel outer rim, the width after pressing blade and tightening is installed the semicircle draught-proofing channel, prevents to be opened by wind and reduce windage when the blade of deflation is circled round;

6, reserve a wide slit of 2CM in the middle of the upper frame with each blade, top at each upper frame, 10 miniature four-wheeled trailers are installed, each trailer bottom hangs the fan blade plate that goes for a drive by the slit, suspension centre in the middle of the lower end of each plate that goes for a drive, is installed one top wheel in the neutral position, plate upper end of going for a drive, a trailer and a top wheel can only prolong frame and roll, and the plate that goes for a drive then rotates with a trailer and a top wheel shaft;

7, at fan blade one of towing plate is installed respectively up and down, being provided with thereafter can be with the flexible retaining of rope control;

8, the wind wheel framework is risen to the rotor shaft top, with cable wire or angle steel that the wind wheel framework is diversionary mutually fixing;

9, at the subcutaneous end of rotor shaft driving gear is installed, will be fixed generator after generator shaft end gear and the interlock of wind wheel gear; Embodiment is all finished since then.

Not only the cut-off wind area is big in the present invention, and with low content of technology, and investment cost also seldom.This design can be intercepted and captured a large amount of wind energies, to popularizing wind-power electricity generation on a large scale, improves atmosphere environment, makes full use of renewable energy sources, has realistic meaning.

Claims

1. retractable vertical shaft type wind turbine of fan blade, its major character is: the blade of wind wheel is to be connected into by the plate that goes for a drive (2) that can fold, and it can be implemented in half revolution under the effect of external force and stretches, and tightens in other half revolution.
