Description

[Detailed description of the invention] The present invention relates to a wind power generator.

Conventionally, there are two types of wind turbines used in wind power generation equipment: those that rotate in a plane perpendicular to the wind direction, and those that rotate with blades installed around an axis perpendicular to the wind direction. The windmill is designed to rotate within a right-angled plane.

However, the efficiency of any wind turbine is between 20 and 4.
The industry is looking forward to the development of efficient wind turbine generators in response to the era of resource conservation.

In consideration of the above points, the present invention is a wind power generation device that generates electricity using a wind turbine mechanism in which a wind tunnel is provided at the front and back positions of a U-shaped support frame and an impeller is pivotally supported inside. , which is characterized by its ability to increase efficiency by making dual use of wind power.

Hereinafter, the present invention will be explained in detail with reference to embodiment figures.

Bearings are provided on the upper surface of the underframe 1 and at the center of the inside of the underframe 1 of a suitable height to pivotally support the rotating shaft 2. A front wind tunnel 7a is provided at the upper end of the front part of the U-shaped support frame 4, into which a real bearing 5 is inserted, the outer circumference is curved inward toward the center, and a number of ventilation passages 6 are protruded at radially symmetrical positions on the outer circumference. A rear wind tunnel 7b is constructed parallel to the direction of the support frame, and has a larger diameter than the front wind tunnel 7a and the same configuration as the front wind tunnel 7a. Part wind tunnel 7a and rear wind tunnel 1
Shafts 9a of impellers 8a and 8b with bearings provided at the front and back center positions inside the impellers 8a and 8b, with blade angles opposite to each other with respect to the wind direction.
, 9b are mounted on shafts, and the rear end of the shaft 9a, the front end of the shaft 9b, and the upper end of the rotating shaft 2 are protruded toward the center of the interval between the wind tunnels to form the shaft 9a.

A bevel gear 10atlOb fixed to the protruding end of the rotating shaft 2 is meshed with a bevel gear 10c fixed to the upper end of the rotating shaft 2, and the interlocking parts of each gear are covered with a split cover 11, and the front and rear wind tunnels 7
A wind turbine mechanism 13 with wind vanes 12 erected on the upper surface of a and 7b is installed on the upper surface of the underframe 1, and the rotating shaft 2 is linked to the automatic speed governor 14 and the generator 15 at a lower position within the underframe 1. This is what we do to make it happen.

At the same time, the effects of the present invention will be explained with reference to embodiment figures.

The windmill mechanism 13 is rotatably supported by the rotating shaft 2 through 360 degrees, and when the windmill mechanism 13 receives wind, the wind direction device 1
2 is above the rear wind tunnel γb, the wind turbine mechanism 13 rotates around the rotating shaft 2 so that the front wind tunnel 7a faces upwind and stops, and the wind turbine mechanism 13 rotates forward by the wind pressure blown into the front wind tunnel Ta. The impeller 8a in the front wind tunnel Ia rotates in the forward direction, and the wind that has passed through the front wind tunnel Ia and the external wind are blown into the rear wind tunnel 7b at the rear, and the wind pressure causes the wind to flow back into the rear wind tunnel 7b. The inner impeller 8b is rotated in the opposite direction, and the rotational force of the impeller 8a>8b rotating in mutually opposite directions is transmitted to the rotating shaft 2 by the bevel gear mechanism 10at1ob, 10c and rotated. Electric power is obtained from a generator 15.

Front and rear wind tunnels 7a. 7b has a central outer peripheral part curved toward the inner surface to shorten the span, so that the blown wind is accelerated in the central part to rotate the impellers 8 a and 8 b, and the outer peripheral surface of the wind tunnel is Since a large number of ventilation passages 6 are provided from the front end to the rear end, the wind flowing through the ventilation passages 6 from the front to the rear attracts and discharges the vortex after rotating the impeller, and the impeller In addition, the wind flow discharged from the front wind tunnel 7a flows into the rear wind tunnel 7b, which is an expanded diameter wind tunnel, together with the external wind flow, rotates the impeller 8b, and transmits the rotational force to the rotating shaft 2. During strong winds, the automatic speed governor 14 installed on the rotating shaft 2 can prevent the rotational speed from rising above a certain level while producing efficient output. A shutter is provided to close the front ends of 7a and 7b to block the wind flow.

It is possible to take out the output by using another energy converter instead of the generator 15, and the above-mentioned remarkable effects can be achieved.
