Description

{Rotor for generator}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rotating body for a generator that generates kinetic energy by rotating in a generator for converting kinetic energy into electrical energy, and more particularly, The present invention relates to a rotating body for a generator that increases the power generation efficiency by rotating the rotating block even when there is no external force because the weight difference between the side on which the center of gravity is shifted and the opposite side is large.

Electric power generation includes thermal power generation using fossil fuel energy, nuclear power generation using radioactive material energy, and hydroelectric power using location energy of water. In recent years, natural energy that can be easily obtained from nature Tidal power using tidal power, wind power using wind power, and solar power using solar heat are being actively developed.

Thermal power generation, nuclear power generation, and solar thermal power generation convert fuel energy into electric energy, and hydroelectric power, tidal power, and wind power generation generate electricity by converting kinetic energy into electric energy.

Generators that convert kinetic energy into electrical energy, such as hydroelectric or wind power generators, generate electricity from the permanent magnet and coil as the rotating body rotates due to the force of falling water or blowing wind, Electrical energy is created. More specifically, the generator comprises a stator having a coil wound thereon and a rotor made of a permanent magnet disposed inside the stator. When the rotor rotates, the rotor of the generator rotates in the stator, and an electromagnetic force is generated between the stator and the rotor . For reference, the generator may have a structure in which the stator is made of a permanent magnet and the rotor is wound with a coil.

In this way, a generator that generates electricity using kinetic energy needs to be rotated in order to generate electricity, which is necessary to rotate the rotating body.

At this time, the energy used to rotate the rotating body is considerably larger than the energy generated by the rotation of the rotating body, so that the power generation efficiency of the generator is not so high.

So, one of the ways to increase the power generation efficiency of the generator is to rotate the rotor with less power (energy).

For reference, disclosed in Japanese Patent Laid-Open No. 10-2010-0115005 entitled " Gravity Generating Device "has been disclosed in the prior art for increasing the power generation efficiency by rotating the rotating body of the generator with less force.

An object of the present invention is to provide a rotating body for a generator capable of rotating at a reduced energy to generate power by rotating in a generator for generating kinetic energy by using kinetic energy.

According to an aspect of the present invention, there is provided a rotary body for a generator,

As shown in the drawing, the rotating body for a generator according to the present invention includes a shaft block 10 to which a shaft 40 is coupled, two rotating blocks 20A and 20B coupled to be symmetrical on both sides of the shaft block 10, And a center-of-gravity conversion induction fluid 30 which is built in the rotary blocks 20A and 20B and converts the center of gravity to the inside and outside in accordance with the rotation direction.

Therefore, the present invention is inexpensive in manufacturing cost, excellent in productivity, and excellent in product competitiveness.

A shaft (40) serving as a rotating shaft passes through the shaft block (10) and is fastened.

Referring to FIG. 3, a generator 50, an accelerator 60, a rotation assist motor 70, and the like are coupled to the shaft 40.

3, a bay ring 41 is coupled to both sides of the shaft 40 passing through the shaft block 10 for smooth rotation, and the bearing 41 is inserted into the support frame 80 , The support frame (80) rotatably supports the rotating body (S).

A generator 50 composed of a stator 53 fixedly disposed outside from the inside of the housing 51 and a rotator 55 rotatably disposed inside the stator 53 is mounted on the rotating body S, Respectively,

The rotator 55 of the generator 50 is connected to the shaft 40 and receives the rotational force of the shaft 40 to rotate.

The shaft 40 of the rotating body S and the rotator 55 of the generator 50 may be connected to an accelerator 60 composed of gears.

The rotating body S according to the present invention rotates at a low speed so that the center of gravity can be changed according to the positions of the rotating blocks 20A and 20B. However, since the volume and weight are large, a strong rotating force ) Is generated.

The accelerator 60 connects the shaft 40 and the rotator 55 so that the low-speed rotation of the shaft 40 is transmitted by the high-speed rotation of the rotator 55 in order to convert this strong rotational force to the maximum electric energy.

The rotation assisting motor 70 rotates the shaft 40 in a section where the rotating blocks 20A and 20B rotate upward to move the rotating blocks 20A and 20B to a position where the rotating blocks 20A and 20B rotate downward.

In other words, when the rotary blocks 20A and 20B are rotated downward, the center of gravity is formed on the outer side so that the rotary blocks 20A and 20B rotate by their own gravitational force, but the rotary blocks 20A and 20B When rotating in the upward direction, energy greater than gravity that hinders rotation is required, and the rotation assist motor 70 supplies the necessary energy.

Various methods can be used to transmit the rotational force of the rotation assist motor 70 to the shaft 40 so that the shaft 40 can be rotated. Referring to the drawings, the shafts of the shaft 40 and the rotation assisting motor 70 are provided with gears 71 and 72 which are engaged with each other.

The rotation auxiliary motor 70 transmits a rotational force to the shaft 40 when the rotational blocks 20A and 20B rotate upward and the shaft 40 rotates when the rotational blocks 20A and 20B rotate downward. It is preferable not to unnecessarily consume energy without interfering with the rotation of the motor.

Therefore, gears for meshing with the gears 71 provided on the shaft of the rotation assist motor 70 or the gears 72 provided on the shaft 40 are formed in the upper direction section by dividing the sections, The rotational force of the rotation assisting motor 70 can be transmitted only in the section in which the shaft 40 rotates upward.

The two rotating blocks 20A and 20B are coupled to each other on both sides of the shaft block 10 so as to be balanced in the right and left directions of the rotating body S. [

The rotating blocks 20A and 20B have an inner space in which the center-of-gravity-converting inducing fluid 30 can be filled.

The inner space of the rotary blocks 20A and 20B includes a linear portion 21 formed linearly in the longitudinal direction and a linear portion 21 extending in the rotational direction from the inner side of the linear portion 21 And an outer enlarged portion 25 extending in the rotational direction from the outside of the straight line portion 21 to be connected thereto.

The inner expanding portion 23 and the outer expanding portion 25 are formed on both sides of the straight line portion 21 in the rotating direction and are directed in opposite directions to each other. That is, referring to the drawings, when the rotary blocks 20A and 20B rotate counterclockwise, the upper rotary block 20A is formed with the inner expanding portion 23 as the upper side and the outer expanding portion 25, The inner enlarged portion 23 is formed on the lower side and the outer expanded portion 25 is formed on the upper side.

The inner extension 23 is adjacent to the rotation center but located on the opposite side of the outer extension 25 with respect to the center of rotation.

Therefore, the center-of-gravity conversion induction fluid 30 is divided into the outer extension 25 of the left rotary block 20A and the inner side of another rotary block 20B located on the left, as shown in [A] The weight difference between the left side where the center of gravity is shifted with respect to the center of rotation of the shaft block 10 and the right side of the opposite side is large so that the rotation block rotates with a stronger force .

The volume of the center-gravity-converting inducing fluid 30 filled in the inner space of the rotating blocks 20A and 20B is equal to the volume of the inner-side extending portion 23 and the outer extending portion 25, , The center-of-gravity conversion induction fluid 30 fills the inner extension 23 or the outer extension 25 according to the position of the rotary blocks 20A, 20B.

The center-of-gravity conversion inducing fluid 30 is rotated by the center of gravity of the rotating blocks 20A and 20B while moving the inner expanding portion 23 and the outer extending portion 25 according to the rotational positions of the rotating blocks 20A and 20B, To be formed on the inner side and the outer side.

The center-of-gravity conversion induction fluid 30 may use a heavy material. However, when a heavy solid material such as iron beads is used as the center-of-gravity conversion induction fluid 30, And the outer expanding portion 25 are large, causing damage. Thus, the center-of-gravity conversion inducing fluid 30 preferably uses a liquid material (i.e., fluid 30).

And the center-of-gravity conversion inducing fluid 30 is moved quickly so that the center of gravity can be quickly changed. Therefore, the center-of-gravity conversion inducing fluid 30 preferably uses a low-viscosity material among the liquid materials.

As such a heavy and viscous liquid material, water or oil is suitable for use as the center-of-gravity conversion inducing fluid 30.

Hereinafter, the rotation of the rotary blocks 20A and 20B and the movement of the center-of-gravity conversion induction fluid 30 will be described with reference to FIG.

First, [A] in FIG. 2 shows a state in which the rotating blocks 20A and 20B are arranged in the left and right horizontal directions.

In the state [A], the upper rotating block 20A is filled with the center-of-gravity converting inducing fluid 30 into the outer extending portion 25, and the lower rotating block 20B is filled with the center- 30 are filled in the inner expanding portion 23.

Thus, in the state [A], the center of gravity of the rotating body S is formed on the left side with reference to the drawing, and the rotating blocks 20A and 20B rotate counterclockwise.

In other words, when the rotating body S is in the state [A], the rotating block 20A disposed at the upper portion moves the center-of-gravity conversion induction fluid 30 from the inner expanding portion 23 to the outer expanding portion 25 As the center of gravity is formed on the outer side, the outer enlarged portion 25 of the rotary block 20A filled with the center-of-gravity conversion inducing fluid 30 is naturally rotated downward. At this time, the rotating block 20B disposed at the lower portion moves the center-of-gravity-converting inducing fluid 30 from the outer enlarged portion 25 to the inner enlarged portion 23 so that the center of gravity is formed on the inner side, So that the entire center of gravity is formed on the left side, that is, on the outside of the rotating block 20A rotating in the downward direction.

In the state [A], the rotation block 20A gradually starts to rotate at a higher speed in the state [B], and then slowly rotates in an upward direction due to inertia.

The rotation block 20A which has been rotated upward by the inertia receives the power of the rotation assist motor 70 in the state [C] before the inertia disappears (i.e., before the rotation block stops and rotates in the reverse direction) So that it rotates. That is, the outer extension 25 of the rotary block 20A filled with the center-of-gravity conversion inducing fluid 30 rotates upward. At this time, the rotation auxiliary motor 70 upwardly rotates the outer expanding portion 25 side of the rotating block 20A rotating upward.

When the rotation assist motor 70 is in the [D] state, the power transmission is stopped. The [D] state is a state [A] in which only the positions of the two rotary blocks 20A and 20B are changed, and from here on again, it is rotated by the magnetic force by the movement of the center of gravity. That is, the [D] state is a state in which the center-of-gravity conversion induction fluid 30 is moved to a position where the rotation block 20B filled in the inner extension portion 23 is rotated downward.

The principle of rotation of the rotating body according to the present invention is that the rotating body rotates by the magnetic force of the center of gravity from the starting position to the downward direction from the starting position to the downward direction as shown in [E] of FIG. 2, And then rotates by the power of the rotation assist motor until the new start position.

While the present invention has been described in connection with the preferred embodiments thereof with reference to the accompanying drawings, it is to be understood that the present invention is not limited thereto. Should be interpreted as falling within the scope of protection.
