Description

WIND GENERATOR {WIND GENERATOR}

[0001] The present invention relates to a wind turbine generator, and more particularly, to a wind turbine generator, in which a rotor of a first rotor and a blade of a second rotor are arranged so as to be shifted from each other, Thereby increasing the rotation speed and improving the power generation efficiency.

Generally, wind power is a clean energy that is not depleted, and is attracting attention as an energy source with the highest growth rate among alternative energy sources. Therefore, in recent years, a wind turbine generator for generating electricity using wind turbine has been actively developed.

Conventional wind turbine generators are known as horizontal wind turbine generators and vertical wind turbine generators, and a hybrid type turbomachine generator is known which combines both horizontal and horizontal turbine generators.

Accordingly, the present invention is an improvement of a conventional horizontal-axis wind turbine generator. First, a "wind turbine generator" of Korean Patent Registration No. 1521619 (hereinafter referred to as " Wind turbine generator ").

The conventional wind turbine generator includes a pillar having a horizontal pipe formed at an upper portion thereof and a vertical shaft projecting at the center of the horizontal pipe, a rotating housing connected to the vertical shaft through a rotating connection means and rotatably mounted around a vertical axis, One or more generators mounted in the housing and each having one or more input shafts protruding outside the rotary housing and the electric lead wires leading out to the outside of the rotary housing; .

The rotor includes a connection bracket mounted on an input shaft and having a radially protruding connection plate protruding from a periphery thereof in a direction perpendicular to the input shaft, and a plurality of blades having inner ends connected and fixed to the protruding connection plates.

According to this structure, a conventional wind power generator can continuously generate electric power by applying a double-sided blade that can be rotated and yawed in the wind direction even if the wind strength is weak or the wind direction changes frequently, There is an advantage that it can produce positive electricity.

However, since the conventional wind turbine adopts a structure in which the blades of the rotors connected to each other via the connecting bracket are connected to both sides of the input shaft connected to the generator with the rotary housing in correspondence with each other in a radial manner, There is a structural problem that the area of the receiving blade may be reduced and the rotational force of the rotor may be deteriorated.

Further, in the conventional wind turbine generator, the rotor is directly connected to the input shaft of the generator, so that the rotation speed of the rotor and the rotation speed of the input shaft are always equal to 1: 1.

Therefore, in the conventional wind turbine generator, the rotation of the rotor is transmitted to the input shaft of the generator at a ratio of 1: 1, so that power generation through the input shaft rotated at the same rotation speed as the rotor is possible. There is an impossible problem.

 Hereinafter, the operation of the wind turbine generator according to the present invention will be described.

First, when electricity is produced by using the wind power generator according to the present invention, the rotation direction of the rotary housing 2 changes correspondingly to the wind direction.

The first rotor 32 and the second rotor 33 disposed in front of the rotary shaft 3 are brought into contact with the wind when the rotary housing 2 changes the direction of rotation along the wind direction, 1 rotor 32 and the second rotor 33 and the rotary shaft are rotated at the same speed.

At this time, the first blade 322 of the first rotor 32 and the second blade 332 of the second rotor 33 are arranged radially shifted from each other about the rotation axis 3, The area of the first and second blades 322 and 332 affected by wind blowing from the first and second blades 322 and 333 is increased, thereby enhancing the rotation efficiency of the first and second rotors 32 and 33 while improving the rotation efficiency.

That is, since the first blade 322 and the second blade 332 are disposed to be offset from each other in front of the rotary housing 2, the total area affected by the wind is maximized, ) Is more influenced by the wind, so that the rotation efficiency can be improved while increasing the rotational force.

The weight of the first rotor 32 and the weight of the second rotor 33 are stacked in the rotation housing 2 adjacent to the generator 5 so that the weight of the first rotor 32, And the second rotor (33) are balanced with respect to the column, thereby enabling stable rotation. That is, since the weights cancel the weight of the first rotor and the second rotor, consequently, the rotating housing can rotate about the column 1 stably.

Next, when the rotary shaft 3 is rotated, a rotational force is transmitted to the gearbox 4 connected to the rotary shaft 3, and the gearbox 4 increases the rotational speed and transmits the increased rotational speed to the generator. The power generation efficiency can be improved by the rotational speed that is increased from the rotational speed of the rotor 32 and the second rotor 33. [

The booster 4 is also connected to the first coupling shaft 42 by the first coupling shaft 42 and the second coupling shaft 43 by the second coupling shaft 42 and the shaft of the generator 5, So that the rotational force can be transmitted stably without disconnection.

As described above, in the wind turbine according to the present invention, a double rotor in which the first blade 322 of the first rotor 32 and the second blade 332 of the second rotor 33 are arranged shifted from each other is applied The rotational speed of the first and second rotors 32 and 33 and the rotation speed of the first and second rotors 32 and 33 and the rotational speed of the rotating shaft 3 are increased by maximizing the area of receiving the wind force, The speed can be further increased and the power generation efficiency can be maximized.
