Abstract

The invention discloses a blade of a wind power generator which controls the ventilation face and the choke face through a movable blade to form into wind difference, wherein the structure of the blade belongs to a vertical axis type, the blade can rotate towards one direction under any wind directions, and the wind energy does work to the power generator through a driving shaft. As the blade is structurally designed to produce the wind difference by the turning off and on of the movable small blade, the wide pressure of the choke face can be made into the maximum status, the wind pressure of the ventilation face can be reduced to the lowest status, the produced wind pressure difference is also comparatively large, and the work done to the power generator is also comparatively large.

Description

Blade of wind-driven generator

Affiliated technical field

The present invention relates to the blade of wind-driven generator, be one and can make full use of the impeller assembly design that wind-force comes the pushing generator generating.

Background technique

A variety of perpendicular axis type wind-driven generator blades are arranged at present, all be to utilize the wind-force difference between the blade to come pushing generator work, but most vane of vertical shaft wind-driven generator all is an every blade all is monolithic, and the relative strut of blade is fixed, its design fails to reach maximum value to the wind-force difference that wind-force produces, and fails farthest to utilize wind energy.

Summary of the invention

For energy more efficient use wind energy, the invention provides a kind of blade that utilizes wind energy more efficiently, it is poor that this design can produce bigger wind-force, produces bigger wind energy.

The technical solution adopted for the present invention to solve the technical problems is: is Blade Design the louvered blade, but be to form big blade by the small leaf of multi-disc single face unlatching, when wind when the front blows, small leaf will be closed, wind-force acts directly on the blade, when wind blows from the negative, small leaf will be opened, and wind-force can pass blade, does not act on the blade, this model utility utilizes its this characteristics to design exactly, reaches the bigger purpose of utilizing wind energy.

The invention has the beneficial effects as follows, can utilize wind energy more efficiently, and aesthetic in appearance, simple in structure.

Label declaration in the drawing: (1). strut, (2). blade linkage rod, (3). the blade external frame, (4). movable small leaf, (5) roller, (6). drive link, (7). foot rest, (8). hole cap, (9). gear train, (10). ball, (11). heelpiece, (12). closed case, (13). generator, (14) small leaf rotating shaft

Embodiment

In Fig. 1, the movable small leaf (4) on strut (1) both sides is by blade linkage rod (2) interlock, when wind when the front blows, the movable small leaf (4) on strut (1) both sides will become unlatching (Fig. 3) on one side and become ventilating surface, close (Fig. 4) shape on one side and become the choke face, make the blade-shaped on both sides become wind-force poor, rotate thereby promote driving-rod (6), thereby the gear train (9) of closed case (12) the inside below driving drives generator (13) generating by gear train (9).

In legend shown in Figure 2, blade external frame (3) across distributes, connect by strut (1), in same wind direction environment, movable small leaf is closed when forwarding the W1 position to, open when forwarding the W3 position to, at W2, wind-force does not act directly on the blade in the time of the W4 position, when wind in any direction blows, blade can be the directed rotation in axle center along drive link (6) all, by drive link (6) energy is passed to generator.

In legend shown in Figure 3, when wind blows from the front, movable small leaf (4) will be opened and become ventilating surface.

In legend shown in Figure 4, when wind blows from the negative, movable small leaf (4) will be closed and be become the choke face.

Claims

1. a blade of wind-driven generator has the blade external frame, and many movable small leaf are equipped with in blade external frame the inside, it is characterized in that: the movable small leaf in the blade frame can be opened or closure according to wind direction, is combined to form ventilating surface or choke face.

2. blade of wind-driven generator according to claim 1 is characterized in that: under same wind-force direction environment, Yi Bian the blade frame on supporting lever both sides becomes the choke face because of movable small leaf, Yi Bian become ventilating surface, being that the axle center is directed along drive link rotates.

3. movable small leaf number is decided according to blade external frame relative size, and promptly the number of small leaf belongs in the scope of " more than or equal to 2 ".
