Abstract
A fan blade which is used in the breeze wind power generation device, including a fan blade main body, is characterized in that the bottom of the fan blade main body is provided with a through hole, and an one-way valve is provided at the through hole of the fan blade windward side; the one-way valve is installed on the fan blade main body through a hinge, and the valve covers the through hole.
Description
(1) technical field
The utility model relates to the parts of breeze wind-power generator, is specially the fan blade that uses in the breeze wind-power generator.
(2) background technique
Normally used fan blade adopts hemisphere or bent plate shape in the breeze wind-power generator, fan blade adopts overall structure, the fan blade that facings the wind obtains thrust, drives the generator rotation, thereby wind energy is converted into electric energy, since fan blade be symmetrically arranged in rotating shaft around, the part fan blade is in down with the wind, the accurate state that facings the wind, and simultaneously, another part fan blade is in against the wind and half contrary wind state, can offset part moment like this, reduce the effective generating efficiency of wind-driven generator.
(3) summary of the invention
At the problems referred to above, the utility model provides a kind of fan blade that uses in the breeze wind-power generator, use it in the breeze wind-power generator, pushing generator rotation effectively when it is in the state of facining the wind, when being in contrary wind and half contrary wind state, can reduce the reverse thrust in the breeze wind-power generator significantly, partial offset is in the pushing torque of the fan blade of state down with the wind, has improved the generating efficiency of breeze wind-power generator.
The technical solution of the utility model is such: it comprises the fan blade body, it is characterized in that: the bottom at described fan blade body is provided with through hole, side in described fan blade body windward side, described through hole is provided with one-way cock, described one-way cock is installed on described fan blade body by hinge, and described valve covers described through hole.
It is further characterized in that: described fan blade body is funnel shape; Its its surface of a side that contains content cavity of described funnel shape fan blade body is the windward side.
The utility model is applied in the breeze wind-power generator, when a side of windward side facing the wind the time, one-way cock is closed, and be in its valve opening of fan blade of state against the wind, and can reduce reverse resistance so significantly, improved the generating efficiency of breeze wind-power generator, thereby avoided in the prior art, fan blade adopts overall structure, and the part thrust moment is cancelled, the shortcoming that generator for electricity generation efficient is lower.
(4) description of drawings
The structural representation that Fig. 1 looks for the utility model master;
Fig. 2 is the rear view after Fig. 1 is backed down by wind;
The schematic representation that Fig. 3 uses in breeze wind-power generator for the utility model.
(5) embodiment
See Fig. 1, Fig. 2, the utility model comprises fan blade body 1, is provided with through hole 2 in the bottom of fan blade body 1, the side in fan blade body 1 windward side, and through hole 2 places are provided with one-way cock 3.See Fig. 1, fan blade body 1 is funnel shape (seeing the fan blade body 1a that is in side direction among Fig. 3); Its its surface of a side (being a side of arrow C indication among Fig. 3) that contains content cavity of funnel shape fan blade is the windward side; One-way cock 3 is installed on fan blade body 1 by hinge 4, and valve 3 covers through hole 2.Describe the working procedure of the utility model in breeze wind-power generator below in conjunction with Fig. 3: natural wind promotes fan blade body 1, the fan blade body 1 that is under the state of facining the wind is produced pushing torque, arrow B is represented wind direction among Fig. 3, arrow A is represented the sense of rotation of fan blade body, rotating shaft 5 is along with fan blade body 1 rotates together, fan blade body 1 has multi-disc, in rotating process, be in state down with the wind like this, the accurate state that facings the wind, against the wind, the accurate fan blade of state against the wind constantly substitutes, effect of inertia in addition, the rotation that rotating shaft 5 does not stop, motor 6 are electric energy with wind energy transformation constantly.When fan blade body 1 is in the state of facining the wind, under the effect of wind-force, the one-way cock 3 sealing through holes 2 of fan blade body 1 inside, meanwhile, be in state, the accurate fan blade body 1 of state against the wind against the wind, the one-way cock 3 of its bottom is backed down by wind sees Fig. 2, wind passes from the passage between one-way cock 3 and the through hole 2, resistance reduces significantly against the wind, like this for the whole generating device, the pushing torque that facings the wind constant and against the wind resisting moment reduce, the absolute value of whole pushing torque increases, and makes generating efficiency be improved.7 is fixing rod.
Claims (3)
1, the fan blade that uses in the breeze wind-power generator, it comprises the fan blade body, it is characterized in that: the bottom at described fan blade body is provided with through hole, side in described fan blade body windward side, described through hole is provided with one-way cock, described one-way cock is installed on described fan blade body by hinge, and described valve covers described through hole.
2, according to the fan blade that uses in the described breeze wind-power generator of claim 1, it is characterized in that: described fan blade body is funnel shape.
3, according to the fan blade that uses in the described breeze wind-power generator of claim 2, it is characterized in that: its its surface of a side that contains content cavity of body is the windward side during described funnel shape wind.
