Wind power generators {An electric generating device using a windmill}

The present invention relates to a wind power generator, and in particular, by stimulating the magnetic pole and the armature installed on the concentric shaft in the opposite direction to double the power generation efficiency at the same wind speed.

Conventionally, wind turbine generators of various mechanical configurations and forms have been proposed, and there is a generator using a windmill, which is represented by patent application No. 2000-76789.

Although not shown, the power generator using the windmill includes a first and second rotary shafts disposed concentrically in the housing and provided with first and second rotary blades which rotate in reverse directions from each other, and gears at the rear end of the first and second rotary shafts. An idler gear supported by a bearing in the housing to engage with the drive, a housing support pillar having rotatably supporting the housing and having first and second connecting shafts fixedly engaged therein by the idler gear therein; It consists of the 1st and 2nd generator which generate | generates electricity by the rotational force of a connecting shaft.

In this configuration, the wind power generator is provided with two first and second rotary blades in one housing, and the first and second generators are installed on the ground, thereby doubling the amount of power generated under the same wind speed. Although there is an advantage of minimizing the number of generators, a plurality of generators have to be installed, the increase in installation cost and difficulty of maintenance has been pointed out as a problem.

It is an object of the present invention to provide a wind power generation device that can realize the ease of installation and maintenance while doubling the power generation efficiency at the same wind speed in view of the above problems.

In order to effectively achieve the above object, in the present invention, the first and second connection shafts driven by the first and second rotary blades rotate the magnetic poles and the armature in opposite directions to maximize the power generation efficiency.

Hereinafter, the preferred configuration of the present invention will be described in detail by the accompanying drawings.

Figure 1 shows the overall configuration of the wind power generator according to the present invention, which schematically shows the components constituting the generator, the detailed illustration of the parts known by the prior application is omitted.

The wind power generator according to the present invention includes first and second rotary shafts 2a and 2b which are arranged concentrically in the housing 1 and are driven in opposite directions by a blade provided at a front end thereof, and the first and second rotary shafts 2a, 2b) rotatably supporting the idler gear 4 installed in the housing 1 and the support pipe 1a of the housing 1 so as to be engaged with the gears 3a and 3b of the rear end and the outer tooth 4b. It has a housing support pillar (8), and gears (5a, 6a) which are supported and installed in the housing support pillar (8) and engaged with the internal teeth (4b) of the idle gear (4) on the upper side, and the generator at the bottom The gears 5b and 6b for driving the same are provided in the prior art.

A feature of the present invention is that the armature 10 and the magnetic pole 11 constituting the generator 9 by the gears (5b, 6b) is rotated in reverse direction to maximize the power generation efficiency.

The generator 9 is provided with a casing 12 fixed to the housing support pillar 8 and rotatably supported in front of the casing 12 so as to have a gear 6b below the second connecting shaft 7b. And a driving outer shaft (15) rotatably supported between the driving gear (13) for driving and driving, the connecting portion (13a) of the driving gear (13) and the casing (12), and the holder (14) fixed at the center thereof. The driven gear 17 is rotatably supported at the center of the drive gear 13 and the rear end of the casing 12, and is connected to the gear 5b at the bottom of the first connecting shaft 7a and the relay gear 16 at the front thereof. And a magnetic pole 11 and an armature 10 installed correspondingly to the holder 14 and the driving shaft 18 so as to rotate in opposite directions to generate electricity.

Here, the magnetic pole 11 is provided with a commutator 19 is extended to the outer surface of the fixed portion 15a of the drive outer shaft 15 to be fixed tightly, the brush housed in the housing portion 12a of the rear end of the casing 12 Although 20 is illustrated as being drawn out through the connection line 21 by contacting the commutator 19, the mechanical configuration and shape of the various modifications can be devised.

The wind turbine generator of the present invention has such a configuration that the first and second rotary shafts 2a and 2b reversely rotate with each other by blades (not shown) which rotate in opposite directions with each other by wind. By engaging the outer tooth 4a of the idle gear 4, the first and second connecting shafts 7a, 7b meshed with the inner tooth 4b of the idle gear 4 are rotated in the same direction.

In this operation, the gear 5b below the first connecting shaft 7a drives the relay gear 16 supported on the housing support pillar 8, and the relay gear 16 constitutes the generator 9. Since the driven gear 17 of the drive shaft 18 is driven, the armature 10 fixed to the center of the drive shaft 18 is driven to either side.

On the other hand, the drive gear 13 supported on the casing 12 is engaged with the gear 6b at the bottom of the second connecting shaft 7b to be driven in the opposite direction to the drive shaft 1a.

Singa operation results in driving the drive shaft 18 and the drive outer shaft 15 in the opposite direction to each other, and thus the armature 10 and the magnetic pole 11 are reversely rotated to generate electricity.

Thus, the present invention wind power generator can rotate the armature 10 and the magnetic pole 11 in the reverse direction to realize the maximization of power generation efficiency by doubling the number of revolutions and the rotor speed, two or more as one generator (9) Since it is possible to obtain a higher power generation than a generator, it is possible to simplify and minimize the mechanical configuration of the wind power generator and to realize the ease of maintenance.
