Abstract

The utility model relates to a wind wheel, which comprises an air guide cover, a wind impeller and a plurality of blades; wherein, the blades are fixed on the wind impeller and are uniformly radial shaped and a strengthening ring is connected between the blades. In the case of strong wind, the utility model can still keep the reliable structure and the original shape; and besides, the blades manufactured by the light material can efficiently work at extremely low wind speed, generally at 5 kilometers per hour; compared with the traditional wind power mechanical applications which require the starting wind speed more than 24 kilometers per hour, the utility model has wide application range, and can be widely applied to the oxygen-enhanced fans, the miniature wind generators, the wind power water pumps and so on.

Description

Wind wheel
Technical field
The utility model relates to wind-powered machine, particularly a kind of wind wheel that is used for windmill.
Background technique
Be applied to the wind wheel on the windmill at present, how constitute by three blades and multiple-blade.Square being directly proportional of the kinetic energy of wind and rotor diameter, simultaneously, the material of blade is light more thin more, then can rotate under low more wind speed.But the material of light and thin type is because its rigidity and strength deficiency are difficult to make the bigger wind wheel of diameter, and wind speed will cause structural instability slightly by force, and easy deformation is damaged.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides that a kind of starting wind velocity is low, structural stability, on-deformable wind wheel.
The purpose of this utility model is achieved in that a kind of wind wheel, comprises air guide lid, fan blade and a plurality of blade, and vanes fixed is the homogeneous radiation shape in fan blade, it is characterized in that: be connected with reinforcer between between the described blade.
Described reinforcer is a circular thin slice, embeds the blade middle part, and processing is simple, and is easy to assembly.
The utility model processing is simple, be provided with the reinforcement annulus, even than still keeping structural stability, not yielding under the high wind, simultaneously, the impeller that adopts light-duty material manufacturing generally just can effectively be worked at 5km/h under very low velocity, requires starting wind velocity to surpass 24km/h with traditional wind-powered machine and compares, have very big Applicable scope, can be widely used on the equipment such as oxygenation blower fan, small-sized wind power generator, wind-power water-pumping machine.
Description of drawings
Fig. 1 is a plan view of the present utility model.
Fig. 2 is a left view of the present utility model.
Embodiment
The utility model is a kind of wind wheel.As shown in Figure 1, 2, comprise air guide lid 1, fan blade 2, a plurality of blade 3 and reinforcement annulus 4.Air guide lid 1 spins with fan blade 2, and central authorities are provided with interior threaded hole, with convenient and live axle connection.The number of blade 3 can be provided with as required.Present embodiment is provided with 12 blades 3, is fixed in fan blade 2 by fixed block, and is that the center is the homogeneous radiation shape with fan blade 2.Blade 3 middle parts have seam, the seam that reinforcement annulus that a sheeting material is made 4 orders are passed each blade 3, and each blade 3 is connected with each other to be positioned, and both has been convenient to processing, can stablize the structure of wind wheel again, prevents distortion.

Claims (2)
