Abstract
The present invention is one wind energy apparatus, and is especially one windmill with no wind vane deceleration caused by wind direction conversion. The present invention includes several wind vanes fixed onto the rotating shaft, and each of the wind vanes consists of one latticed body and one netted body superposed and wound to form one wind catcher, with each latticed body having one wind curtain hinged. In back wind, the netted body pushes against the wind curtain and the wind vanes rotate with wind; and in tail wind, the wind curtain is blown to open and the wind vanes have no counter force applied and no deceleration to maintain its work producing capacity.
Description
Technical field
The present invention is a kind of device that utilizes wind energy as power resources, particularly a kind ofly makes the reverse windmill that the windmill rotating speed is slowed down when stressed of fan blade at wind direction.
Background technique
In the prior art, windmill is formed by some fan blades, when the wind blows fan blade, fan blade will drive the work mechanism acting by rotating shaft, in the fan blade rotation process, when having only fan blade to run into against the wind, could give windmill with power, and with the wind the time, wind direction can make fan blade reverse stressed on the contrary, and then the windmill rotating speed is slowed down, reduced the ability of external acting.
Summary of the invention
The objective of the invention is to invent and a kind ofly make the reverse windmill that the windmill rotating speed is slowed down when stressed of fan blade at wind direction.
The present invention realizes as follows: the present invention includes a plurality of fan blades, fan blade is fixed in the rotating shaft, being curled into the arc state of going for a drive after fan blade is superposeed by a trellis body and a reticular body forms, reticular body should be positioned at the outer surface of fan blade arc, and the upper edge of each grid is all by the hinged air curtain of hinge.
Grid on the fan blade is a rectangle, and air curtain also is a rectangle, and equal and opposite in direction.
In use, when running into against the wind, reticular body withstands air curtain, fan blade just can rotate with the wind, when running into the wind in the fan blade rotation process, wind-force just blows air curtain open, makes air-flow pass grid and does not make fan blade reverse stressed, therefore the rotating speed of windmill just can not slow down yet, and has kept the ability of the original external acting of windmill.
Description of drawings

Fig. 2 is blade structure figure of the present invention
Among the figure, 1 fan blade, 2 rotating shafts, 3 trellis bodies, 4 reticular bodies, 5 air curtains, 6 hinges, 7 grid.
Embodiment
Shown in Figure 2 as Fig. 1, the present invention includes a plurality of fan blades 1, fan blade 1 is fixed in the rotating shaft 2, being curled into the arc state of going for a drive after fan blade 1 is superposeed by a trellis body 3 and a reticular body 4 forms, reticular body 4 should be positioned at the outer surface of fan blade 1 arc, and the upper edge of each grid 7 is all by hinge 6 hinged air curtains 5.
As shown in Figure 2, the grid 7 on the fan blade 1 is a rectangle, and air curtain 5 also is a rectangle, and equal and opposite in direction.
Claims (2)
1. windmill, it comprises a plurality of fan blades, and fan blade is fixed in the rotating shaft, it is characterized in that: be curled into the arc state of going for a drive after fan blade is superposeed by a trellis body and a reticular body and form, reticular body should be positioned at the outer surface of fan blade arc, and the upper edge of each grid is all by the hinged air curtain of hinge.
