Abstract
Disclosed is a wind-guiding type wind-driven machine, comprising a wind board, rotating wind vanes, a vertical shaft, a supporting guiding rail, a brake, etc. The extension line of the wind board and the circle with the largest radius made by the rotating wind vanes are always intersecant. The utility model has the advantages of effectively overcoming the resistance of dead wind, fully utilizing wind power, improving the stress of the rotating part, steadily running and increasing the whole machine power.
Description
The utility model belongs to wind energy conversion system, exactly is the vertical pivot wind energy conversion system that is provided with wind-guiding device.
Existing vertical pivot wind energy conversion system has two classes, a class be lift-type, another kind of be resistance type.The former efficient height, but starting difficulty, poor stability, latter's moment is big, easily make, but there is reverse resistance in rotating blading, and efficient is low.
Known a kind of " dual fan blade vertical pivot wind energy conversion system " applying date: 85829, application number: 85203566 have provided design proposal as shown in Figure 1: base (4) and loam cake (5) have the same diameter circle plate-like thing of axis hole for the center, and vertical pivot (3) passes lower shaft hole.Uniform rotating blading (2) on the vertical pivot, this fan blade is preferably curved.Uniform static fan blade (1) 6-16 sheet outside the rotation area of rotating blading (2) and between the base circumference, this static fan blade (1) vertical fixing is between loam cake (5) and base (4).Every static fan blade (1) intersects at a point with the circumference of base (4), draw radius from intersection point to the center of circle, then static fan blade (1) is 15 °～30 ° with the angle of this radius, but be preferably between 20 °～25 °, establish movable air door (6) between the adjacent static fan blade, this air door can move along static fan blade, can close when withstanding adjacent static fan blade, can be with the air channel complete closed between the adjacent fan blade when closing.
The advantage of this scheme is: overcome the reverse resistance of fan blade, and changed this resistance into the power identical with the fan blade sense of rotation; Simple in structure, be convenient to braking and maintenance, mechanical efficiency significantly improves.
But there is following shortcoming in this scheme: the movable air door that () moves along static fan blade has limited the position relation of rotating blading and static fan blade, the radius that is rotating blading must be less than the center of circle to the perpendicular distance of static fan blade (or its elongation line), otherwise the switch of air door will influence the rotation of fan blade.Go out to send to investigate this design proposal from this basic point, effective blowing area of inaccurate this wind energy conversion system of discovery is less.If the static fan blade and the length of rotating fan blade are than being 1:1, then effective blowing area of this wind energy conversion system be the wind deflector height 1.4-1.8 doubly.(2) the convergent contour passage that forms between the static fan blade is too narrow, and screening area is excessive, causes the most of area of rotating blading not to be subjected to wind-force, and wind energy utilization is relatively poor.(3) regulate air output by movable air door,, cause the waste of part wind energy with this speed of controlling wind energy conversion system.The structural feature of this scheme is unfavorable for developing the plane large scale wind power machine.(5) the rotating part quality is less, rotary speed unstabilization.
At above-mentioned shortcoming, the utility model air guide type wind energy conversion system has proposed a kind of new design proposal.The air guide type wind energy conversion system is made of wind deflector, vertical pivot, fan blade, loam cake, base, energy delivery mechanisms.Structure such as Fig. 2, shown in Figure 3.Wind deflector (11) is uniformly distributed in outside the rotation area of fan blade (12), and the elongation line of wind deflector (11) cuts mutually with the circle of the formed radius maximum of fan blade (12) rotation all the time.Wind deflector is fixed between base (5) and the loam cake (10), and quantity is advisable with the 6-12 piece.Wind deflector is preferably 120 °～150 ° near the end points (11a) of rotating blading with the line in the center of circle and the angle α of wind deflector formation.
It is less that this design proposal has solved " dual fan blade vertical pivot wind energy conversion system " blowing area effectively, the problem that wind energy utilization is lower.Under the wind deflector quantity condition identical with physical dimension, effective blowing area of this air guide type wind energy conversion system can be brought up to 2.4-3.2 times of wind deflector height.And screening area is suitable, and wind-force can act on the whole rotation fan blade, and the utilization of wind reaches better state to make counter blow become forward.
Consider and develop big-and-middle-sized wind energy conversion system in the plane, air guide type wind energy conversion system of the present utility model, it is the annular brace guide rail (6) at center with vertical pivot (1) that one circle is set on base (5) at least, the ring-shaped guide rail of diameter maximum is " L " type structure, the purpose that guide rail is set is to improve the stress of rotating part, improves the smoothness of operation of wind energy conversion system.Contact for rolling between the supporting surface of fan blade (12) and guide rail (6).
For control wind energy conversion system rotating speed is no more than safety value, prevent that storm wind from damaging wind energy conversion system, this air guide type wind energy conversion system near the position of diameter maximum support guide rail (6), is provided with centrifugal friction break (13) every fan blade lower end.After the fan blade rotation reached certain speed, brake slipper (2) overcame the pulling force of spring (4) and the contacts side surfaces of guide rail (6) produces friction, controls the fan blade rotating speed with this.
Machine for doing work requires wind energy conversion system that more stable rotating speed is arranged, and running steadily under the situation that wind speed changes.Air guide type wind energy conversion system of the present utility model, the lower end in vertical pivot (1) has disposed big flywheel gear (9), and this gearwheel both can increase the inertia of rotating part, stablized the wind energy conversion system rotating speed, can drive machine for doing work again.
Energy delivery mechanisms part of the present utility model adopts many group loads to work simultaneously or the form of single work, can utilize wind energy more fully.Many group loads were worked simultaneously when wind was big, hour one group work of wind or no load running.
In sum, air guide type wind energy conversion system of the present utility model can more effectively overcome the counter blow resistance, utilizes wind energy more fully.The stress of rotating part improves.Rotating speed is more stable, and complete machine power can reach higher level.
Fig. 1 is " dual blade shaft wind energy conversion system " plan view.Among the figure: the static fan blade of 1-, 2-rotating blading, 3-vertical pivot, 4-base, the movable air door of 6-.
