Description

Induced air type wind turbine

Technical field

The utility model relates to a kind of wind turbine of used for wind power generation, relates in particular to a kind of induced air type wind turbine with air inducing structure.

Background technique

Various wind turbines are arranged in the prior art, and great majority are applied on the wind-power electricity generation.Common wind-driven generator is installed in the place, air port in broad area, its structure comprises: contain the main body of magnet and coil, main body one end is provided with by three rotors that blade is formed that are evenly distributed on the circumference, and rotor is provided with three blades, each blade is about about 40 meters, and requisite space is very big.When certain direction be the wind comes from, wind-force promoted the blade rotary electrification.In the patent application of publication number CN1980014A, disclose a kind of large-scale wind power generator in addition, be characterized in being provided with rotor at the main body two ends.Yet when above-mentioned two kinds of wind-driven generators not quite can't promote the blade rotation when wind-force, this moment, wind-force can not be used for generating electricity, and it is very big similarly to take up room.

Summary of the invention

The purpose of this utility model is to solve the above-mentioned problems in the prior art, and a kind of induced air type wind turbine that more can make full use of wind-force is provided.And it is little to take up room, and it is big to obtain wind energy.

For achieving the above object, induced air type wind turbine of the present utility model comprises induced air pipe and wind wheel, and described wind wheel is provided with a plurality of blades, and described induced air pipe is the little shape of inlet large outlet, and the outlet of induced air pipe is corresponding with one of them leaf position.

In the such scheme, described induced air pipe is taper type.Can be square cone or frustoconic shape.

In the such scheme, described blade is 3-10.And described blade is preferably on the wind wheel uniform.

The beneficial effect of induced air type wind turbine of the present utility model is:

1. raising utilization ratio of wind energy." horn mouth " formula induced air pipe can be concentrated the wind of large volume on the space and introduce and discharge from little outlet, therefore the wind speed that is introduced to outlet is far longer than the mean wind velocity in same time, same place, effectively blow to each blade that rotates to the outlet port successively, reach the purpose that promotes the wind turbine rotation.

2. under the situation that obtains same wind energy, the shared volume of the utility model wind turbine is much smaller.

3. this wind turbine is simple for production, and cost is low, and of many uses.This wind turbine can be installed on automobile, train or the steamer, drives various generator for electricity generation to solve the usefulness of heating and illumination; Also can be installed in and drive generator for electricity generation in the electric motor car, will emit electrical power storage and behind storage battery, can drive the electric motor car operation again; Also can be used on the outdoor open-air wind-driven generator purposes.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing and two preferred embodiments:

With reference to Fig. 1-Fig. 4, induced air type wind turbine of the present utility model comprises induced air pipe 1 and wind turbine 2, the wind wheel of wind turbine 2 is provided with 8 blades, blade is uniform on wind wheel, induced air pipe 1 is taper type, outside inlet 15 is big, and inside outlet 16 is little, and the outlet 16 of induced air pipe is corresponding with blade 21 positions.Induced air pipe 1 can be square cone, is made up of upper and lower induced draft plate 11,12 and left and right induced draft plate 13,14.Induced air pipe 1 and wind turbine 2 are separately fixed in the casing 3, wind turbine 2 is connected with casing by the support 22 that is fixed on casing 3 bottom surfaces through central shaft 24, the promptly big mouth of the inlet 15 of induced air pipe 1 is fixed on a side of casing 3, and the outlet 16 of induced air pipe 1 is that osculum faces the position that blade can be rotated to.Spring 23 plays the effect that makes outlet 16 location.

Described induced air pipe can be frustoconic shape, is made up of the induced draft plate of two half cone-shaped.In like manner, induced air pipe also can be toroidal, is made up of the induced draft plate of two semi-surface shapes.

Above-mentioned induced air type wind turbine can be installed on automobile, train or the steamer.According to actual conditions, can remove casing 3.

With reference to Fig. 5, induced air type wind turbine of the present utility model is used for outdoor wind-driven generator, generally needs casing 3.The front of wind turbine and the left and right sides are being kept off, and only expose blade, and wind can only blow to a blade, integral body that can not blower.

Fig. 6 and Fig. 7 illustrate another kind of embodiment of the present utility model, wherein, upper and lower induced draft plate 11 ', 12 ' and left and right induced draft plate 13 ', 14 ' formed induced air pipe, the outlet 16 of induced air pipe ' corresponding with blade 21 ' position.Wind wheel is provided with 6 uniform blades.

The utility model utilizes " waterwheel " principle, by " horn mouth " formula induced air pipe the wind in space is focused on the osculum and emits, and wind effectively blows to each blade that rotates to successively on the exit position.Utilize this principle to make and vary in size, different induced air type wind turbine.
