Embodiment

For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.

Embodiment

Below, according to an example of the bright wind generating unit of the present invention of Fig. 4～figure 6 Said.

Moreover, at the bright Time of Said, adopt identical label with the same part of prior art, corresponding explanation is omitted.

Fig. 4 is the schematic perspective view of an example of wind generating unit of the present invention, and Fig. 5 is the floor map of blade bottom among Fig. 4; Fig. 6 is the schematic cross-section of blade among Fig. 4.

With reference to the accompanying drawings, 10 be with prior art in the blade body of identical blade 3, running shaft 1 is fixedlyed connected with blade body 10 with web 4d by land 5, connecting rod 4c.

11 is to comprise that first section that engages the linking department 11c that links between facial 11a and the second facial 11b of joint and the first facial 11a of joint and the facial 11b of second joint that engages with the following inwall 10a and the top inwall 10b of blade body 10 is the crosspiece of breach word shape.

Behind near the two ends of the long side direction of blade body 10 the length setting, the following inwall 10a of blade body 10 and the end of top inwall 10b engage one another, and the reinforcement of the twisting strength of blade body 10 is bent to form by sheet metal.

12 is reinforcing plate, the following inwall 10a that reinforcing plate 12 is fixed on the short side direction of blade body 10 go up or the top inwall 10b of the short side direction of blade body 10 on.

As mentioned above, the following inwall 10a and the top inwall 10b of blade body 10 engage one another by crosspiece 11, have strengthened blade body 10 twisting strength when rotated.

15 is the outstanding rotational speed inhibition plate that is provided with in following below of the long side direction of blade body 10, and rotational speed suppresses plate 15 and blade body 10 constitutes blades 16.

The section of blade body 10 is the main wing shape of aircraft, wind makes blade 16 produce climbing power, make blade 16 rotations, rotational speed suppresses the plate 15 outstanding following belows that are arranged on blade body 10, the climbing power that blade 16 produces makes rotational speed suppress plate 15 and produces resistance, make wind-force produce inhibition, be suppressed at effectively and rotate through surplus damage under the high wind blade 16 to the rotation of blade 16.

Moreover in this example, crosspiece 11 is arranged in the length range near the two ends of long side direction of blade body 10 length and blade body 10 two ends, and crosspiece 11 can carry out suitable setting according to the user mode of wind generating unit.

When the plat part 4e of the end of connecting rod 4c and web 4d is connected to each other and inserts the groove 10c that is connected to blade body 10, be connected with crosspiece 11 one.

Simultaneously, be connected to each other between blade body 10 and crosspiece 11 or the web 4c, can adopt known rivet to connect, other known reinforcement by connection means such as welding are perhaps in conjunction with other means.

Simultaneously, in this example, can connect on the short side direction of blade body 10 stiffening plate 12 is set, like this, the intensity of blade body 10 will further be strengthened.

Moreover, in this example, illustrated that the making of blade body 10 usefulness sheetmetals forms, can add glass fibre and carbon fiber to improve the intensity of blade body 10; And being provided with between the inwall up and down of blade body 10 engages first and engages the such design of crosspiece 11 that facial 11a and second section that engages facial 11b are breach word shape, can obtain identical effect too.

Simultaneously, it is integrally formed (for example that rotational speed suppresses plate 15 and blade body 10, integrally formed by sheet metal, that resin is integrally formed etc.), but also may be that rotational speed suppresses plate 15 and blade body 10 is made by sheet metal or resin forming respectively, adhere to by screw again or weld etc. that known installation method suppresses plate 15 with rotational speed and blade body 10 is fixed together.

If rotational speed suppresses plate 15 and blade body 10 is made by sheet metal or resin forming respectively, the rotational speed that can make several difformities, different resistances in advance suppresses plate 15, select corresponding rotational speed to suppress plate 15 according to the wind behaviour that the place is set of wind generating unit, be fit to be installed on the blade body 10, install at the scene, place that is provided with that is adapted at wind generating unit.

As mentioned above, in this example, suppress plate 15 owing on blade body 10, added rotational speed, follow the wind-force of the climbing power of blade 16 to suppress plate 15 generation resistances by rotational speed, make the weakening of climbing power of blade 16, the rotation of blade 16 is suppressed, and the durability of wind generating unit under high wind is improved.

Moreover, the inhibition effect of rotational speed inhibition plate 15 can improve the durability of wind generating unit in the high wind environment of estimating, further, blade body 10 is made of newly-designed crosspiece 11, improved the intensity of blade body 10, the intensity of wind generating unit is improved.

That is, according to the structure of the blade 16 of the raising intensity of above-mentioned 2 groups of wind generating units, in order to adapt to the environment that the place is set of wind generating unit, 2 groups of blades 16 can all be arranged to said structure, also can have only 1 group of blade 16 to be arranged to said structure.

Wind generating unit of the present invention, the intensity by means of blade 16 under high wind improves, and has expanded the range of choice that the place may be set of wind generating unit.

More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.
