In modern times, electricity has become an essential element of life. As a method of obtaining such electricity, a method of converting thermal energy generated by burning fossil fuels such as petroleum, coal, and natural gas into electrical energy is used. However, fossil fuels have a limited amount of resources. In addition, there is a problem that the air is polluted by the gas generated in the process of burning fossil fuel.

Because of these problems, instead of fossil fuels, electric energy is obtained by converting into electric energy using hydro, tidal, and wind power as energy sources in natural phenomena. In order to convert hydraulic or tidal power and wind power into electrical energy, the kinetic energy generated by the flow of fluid including water and wind must be obtained. The kinetic energy generated by the flow of the fluid is used as an energy source to collect the kinetic energy by rotating the aberration, the propeller, the pinwheel, and the wing.

The kinetic energy due to the rotational motion is related to the velocity of the rotational motion and the mass of the aberration, propeller, pinwheel, and wing that produce the rotational motion. In other words, the kinetic energy is proportional to the velocity of mass and rotational motion. However, the speed of rotational motion cannot increase indefinitely due to physical limitations, which increases the mass of aberrations, propellers, vanes, and wings. In addition, it is possible to increase the volume of aberration, propeller, pinwheel, wing, etc., and increase the range of influence on hydraulic, tidal, and wind power through the deformation of the shape.

For this reason, many studies have been conducted on the deformation of aberrations, propellers, pinwheels, and wings in hydraulic and wind power generation devices.

1 is a schematic configuration diagram of an energy shaft (energy sharft) according to an embodiment of the present invention.

The energy shaft (hereinafter referred to as 'the present energy shaft') 100 according to one embodiment of the present invention includes a shaft 10.

Referring to FIG. 1, the shaft 10 is used as a rotation axis of the present energy shaft 100, and the components of the present energy shaft 100 are positioned to be attached or added to the shaft 10. In addition, the rotational force generated while the shaft 10 itself rotates becomes an energy source that is converted into electrical energy.

Referring to FIG. 1, the energy shaft 100 includes a plurality of main blades 20 mounted around the shaft 10 to collect kinetic energy of the fluid. Each of the plurality of main blades 20 has a first resistance member 21 extending from the circumference of the shaft 10 and a second resistance surface for the flow of fluid so that a first resistance surface 21a for the flow of fluid is formed. And a second resistance member 22 extending from the end of the first resistance member 21 to form a 22a.

Here, the main blade 20 may be used as a medium for transmitting the energy to the rotating shaft to start the rotational movement by receiving the kinetic energy of the fluid flow. Therefore, the main blade 20 may include a first resistive surface 21a and a second resistive surface 22a to easily start the rotational motion by receiving the kinetic energy of the fluid flow. The first resistance member 21 extends from the circumference of the shaft 10 so that the first resistance surface 21a is formed, and the second resistance member 22 is formed of the first resistance member ( Bent from the end of 21) and extend. For example, the first resistance member 21 and the second resistance member 22 may be connected in a “-” shape. When the first resistance member 21 and the second resistance member 22 are connected in a “a” shape, a resistance surface for a fluid that does not flow in a certain direction is formed in two directions due to the characteristics of the fluid flow, thereby providing a flow of fluid. Much easier to convert to rotary motion.

For example, when the present energy shaft 100 is installed in an environment in which a flow of a non-uniform direction is present, the resistance surface is composed of one by including the first resistance surface 21a and the second resistance surface 22a. It is easier to collect the kinetic energy due to the flow of fluid than the blade. In addition, the first resistance member 21 and the second resistance member 22 are bent and connected to each other so that the flow of fluid acting on both surfaces of the first resistance surface 21a and the second resistance surface 22a is greater. Can collect kinetic energy.

The main blade 20 of the "a" shape is located on the shaft 10, and only one main blade 20 has difficulty in collecting kinetic energy due to the flow of the fluid. You can add it to (10).

In addition, for example, in order to increase the stability and efficiency of the main blade 20, the first resistance member 21 and the second resistance member 22 may be formed in a streamlined shape so that the surface to be connected is the center. The streamlined shape may not only refer to the shape of the bottom of a general ship, but may be a curved shape having one or more curvature radii.

In addition, referring to FIG. 1, a plurality of main blades 20 may be provided on the shaft 10. For example, when two main blades 20 are mounted on the shaft 10, as shown in FIG. 1, the angles of the first resistance surfaces 21a of the respective main blades 20 are 180 degrees to each other. Mounting is preferable in view of uniformly and continuously receiving the flow of fluid. As another example, when the three main blades 20 are mounted, the first resistance surface 21a of each main blade 20 may form 120 degrees. In addition, when the four main blades 20 are mounted, the first resistance surface 21a of each main blade 20 may be 90 degrees.

On the other hand, when the depth of the fluid flow is deep, the present energy shaft 100 can be used by connecting a plurality in the axial direction.

Arrangement of the second resistance member 22 of the main blade 20 is an example, the second resistance member 22 of each of the plurality of main blades 20 is the same direction relative to the rotation direction of the shaft 10. To face. For example, the second resistance member 22 of each of the plurality of main blades 20 may be constantly arranged in a tangential direction in contact with the circumferential direction of the shaft 10. In this case, the first resistance member 21 and the second resistance member 22 are connected in a "-" shape. As another example, the second resistance member 22 of each of the plurality of main blades 20 may be disposed such that an angle formed with the tangential direction in the circumferential direction of the shaft 10 is constant. In addition, the direction of the second resistance member 22 may extend in a reverse direction based on the rotation direction, but when the plurality of main blades 20 are mounted, the second resistance members 22 of the respective main blades 20 are in the same direction. Must be extended to

Also, referring to FIG. 1, the energy shaft 100 is a lifting blade for providing lifting force to the shaft 10 so that the load and friction applied to the lower support 40 to be described later during rotation of the shaft 10 are reduced. blade) 30.

In addition, referring to FIG. 1, the energy shaft 100 may include a lower support part 40 rotatably supporting a lower portion of the shaft 10.

The lower support 40 may include a thrust bearing for restraining axial and radial movement of the shaft 10 and reducing friction generated when the shaft 10 rotates. By way of example, the lower support 40 itself may be a thrust bearing, or although not shown in the drawing, the lower support 40 may include a lower support block and a thrust bearing mounted to the lower support block.

In addition, referring to Figure 1, the lower force of the first resistance member 21, so that the lifting force is generated against the resistance of the fluid generated during the rotation of the main blade 20 to reduce the load and friction applied to the lower support 40 A lifting plate 35 protruding obliquely downward in a direction in which the first resistance surface 21a is formed from the lower end of the second resistance member 22 and a lifting plate 35 protruding obliquely downward in a direction in which the second resistance surface 22a is formed. It may comprise one or more of the plates 35. For example, the lifting plate 35 is attached to the lower portion of the main blade 20 to maintain a constant angle to the horizontal flow of the fluid to provide lift to the present energy shaft 100. By way of example, the constant angle for the horizontal flow of fluid may be 45 degrees.

In addition, referring to FIG. 7, the first and second resistance surfaces 21a and 22a may have a lift force that may reduce the load and friction applied to the lower support 40 when the shaft 10 rotates. It may be formed to form a slope with respect to the axis of rotation. When the resistance surfaces 21a and 22a of the main blade 20 are formed to form a slope with the axial direction, a lift force is generated on the energy shaft 100 when the main blade 20 is rotated, thereby acting on the lower support 40. And friction can be reduced.

In addition, referring to FIG. 1, the energy shaft 100 may include an upper support part 50 rotatably supporting an upper portion of the shaft 10.

The upper support 50 may serve to restrain the radial movement of the shaft 10.

It may also include a radial bearing to be mounted.

Referring to FIG. 1, the shaft 10 may include a coupling 60 to be mechanically connected to the driven device 70 to be described later.

In addition, referring to FIG. 1, the energy shaft 100 may include a driven device 70 that receives a rotational force of the shaft 10.

For reference, the energy shaft 100 orthogonal to the flow of the fluid does not mean that the angle between the energy shaft 100 and the flow of the fluid should be made exactly 90 degrees. This is because it is impossible to arrange the energy shaft 100 to be uniformly orthogonal to the overall flow of the fluid because the flow of the fluid changes minutely every minute. Thus, the energy shaft 100 is orthogonal to the flow of fluid in such a way that the angle formed with the main flow of the fluid is approximately 90 degrees so that the energy shaft 100 can collect the kinetic energy from the flow of the fluid as efficiently as possible. It is a concept that involves placing.
