Description

[DESCRIPTION] [Invention Title]
WIND DISPERSION APPARATUS OF WIND POWER SYSTEM [Technical Field] The present invention relates to a wind power system for generating electricity by using a wind force, and more particularly, to a wind power system capable of enabling a rotor to efficiently rotate by using an air compressor (turbo) and an air suction plate and reducing power consumption due to an air compressor (turbo), at the same time. [Background Art]
Wind and photovoltaic power systems generate clean energy. The wind and photovoltaic power systems have been continuously researched and commercialized by nations of the world.
A conventional power system generally employs the photovoltaic system. But, the photovoltaic power system is not efficient, since the photovoltaic power system is largely influenced by a change in wheather .
On the contrary, the wind power system can supply power even in bad weather without sunshine. In the country having many mountains, the wind power system is more efficient than the photovoltaic system. In order to efficiently use wind in the wind power system, a structural combination of a rotator (rotor) constructing the wind power system has to be easily performed and rotate efficiently.
That is, in order to enable the rotor to rotate in a high speed, the wind power system has to efficiently use wind. Accordingly, it is required to improve blades. The rotation speed of the rotor is improved to some degrees by improving the blades. However, it is limited to improve the blades. Techniques for basically increasing a rotation speed of a rotor have been researched. [Disclosure] [Technical Problem] The purpose of the present invention is providing a wind power system capable-of increasing torque by increasing a rotation speed of a rotor by dispersing air to a back of an air suction plate so as to prevent rotation of the rotor from being interrupted by air that rotates around the rotor in order to obtain optimal efficiency of power generat ion even at a low wind speed by instal 1 ing the air suet ion plate. The other purpose of the present invention is providing a wind power system capable of improving power generation efficiency by reducing power consumption for moving an air compressor (turbo) 1 so as to move the air compressor (turbo) 1 to the front side of wind by driving a motor 11 lying over the housing 3 by using a force of wind colliding against an air suction plate 2. [Technical Solution]
According to an aspect of the present invention, there is provided a wind power system comprising a basic skeleton obtained by fixedly connecting a housing 3, a supporting plate 5, and a body 6; a rotor 4 connected to a central axis 9 through a bearing 10 in the housing 3; and an air compressor (turbo) 1 gathering and compressing air and transferring the air to the rotor 4, wherein an air suction plate 2 is installed and connected through wires and chains so as to be movable by using wheels 13 on the supporting plate 5, so that the air suction plate 2 rotates together with the air compressor (turbo)
1 as a single body, when the air compressor (turbo) 1 is located at a front side of wind by using a wind direct ion sensing unit and control and driving units. [Advantageous Effects]
As described above, in the present invention, the air suction plate 2 is combined in a conventional wind power system, thereby increasing rotational power of the rotor 4. In addition, since power consumption used for moving the air compressor (turbo) 1 by driving the motor 11 lying over the housing 3, so that the air compressor (turbo)
1 is located at the front side of a wind direction, is reduced, the power generation efficiency is improved.
Accordingly, it is possible to efficiently generate power by using a wind power system according to an embodiment of the present invention.

To achieve the above mentiond purpose, the present invention provides a wind power system comprising: a basic skeleton obtained by fixedly connecting a housing 3, a supporting plate 5, and a body 6; a rotor 4 connected to a central axis 9 through a bearing 10 in the housing 3; and an air compressor (turbo) 1 gathering air, compressing the air, and transferring the compressed air to the rotor 4, wherein an air suet ion plate 2 having a rectangular shape has an upper end meshed with an upper circular pipe 15 of the housing 3 through rollers and gears and a lower end installed with wheels 13 passing along a rail 19 on the supporting plate 5 is movably connected through wires or chains so as to be integrated into the air compressor (turbo) 1 so that friction on the rail 19 on the supporting plate 5 is minimized. [Mode for Invention]
Hereinafter, an embodiment of the present invention will be described in detail with reference to accompanying drawings.
The attached drawings relates to a huge structure with a diameter of about 50 m having a large output capacity of 3 MW.
FIG.1 is a perspective view of a wind power system of the present invention. The wind power system includes a basic skeleton obtained by fixedly connecting a housing 3, a supporting plate 5, and a body 6, an air compressor (turbo) 1 movably connected to the housing 3 and the supporting plate 5, and an air suction plate 2. Each component is strengthened by using a truss structure.
FIG. 2 is a perspective view of a wind power system in a case where an air compressor (turbo) 1 is located at a front side of wind. In FIG.2, positions of the air compressor (turbo) 1 and the air suction plate 2 are shown.
FIG. 3 is a perspective view of the wind power system for illustrating a structure of the air compressor (turbo) 1. The air compressor (turbo) 1 has a multistage triangular shape in a horizontal direction. The air compressor (turbo) 1 is constructed with rectangular plates in a vertical direction. Accordingly, the air compressor (turbo) 1 is partitioned. An upper end of the air compressor 1 meshes with an upper circular pipe through rollers, gears, and the like so that the air compressor (turbo) 1 is rotatable. Wheels 13 passing along a rail 19 on the support ing plate 5 are installed under a lower end of the air compressor 1. The air compressor 1 moves to the front side of wind, gathers air, compresses the air, and transfers the compressed air into blades 7 of the rotor 4.
FIG. 4 is a side sectional view of a wind power system for illustrating an internal structure thereof . FIG.5 is a top plan view of the wind power system of FIG. 1. In the housing 3, six-stage circular pipes are vertically connected through connection rods at a constant spacing. Uppermost and lowermost circular pipes 15 and 16 are radially connected to a central axis 9 to be fixed to the supporting plate 5 located at the lower end of the housing 3.
The air compressor (turbo) 1 and the air suction plate 2 are movabIy attached to a side of the housing 3. A wind direction sensing unit 14 is installed at the upper part of the central axis 9. Control and driving units are installed at a machine room 12 located at the lower part of the central axis 9. Accordingly, the wind power system is driven so that the air compressor (turbo) 1 is located at the front side of wind based on the wind direction and so that the air suction plate 2 is located to make symmetry with the air compressor (turbo) 1.
The supporting plate 5 with a disk shape is mounted on the upper end of the body 6. The rail 19 is installed on the circumference of the support ing plate 5, so that the wheels 13, which are installed under the lower end of the air compressor (turbo) 1 and under the air suction plate 2, pass along the rail 19.
The body 6 with a cylindrical shape serves as a column for supporting the wind power system.
The rotor 4 is constructed with a drum 8 and blades 7. The blades
7 are attached on the circumference of the drum 8 at a constant spacing.
The drum 8 having a hoi low cylindrical shape is fixedly connected to a radial bearing 10 installed at the upper and lower ends of the central axis 9. When the rotor 4 rotates, as wind blows, the central axis 9 is fixed, but the rotor 4 freely rotates through the bearing
10.
FIG. 8 is a top plan view illustrating relative sizes and directions of an air compressor (turbo) 1 and an air suction plate 2. FIGS.9A to 9C illustrate examples illustrating various shapes of the air compressor 2 that is an -part of FIG.8. The upper end of the air suction plate 2 having a rectangular shape meshes with the upper circular pipe 15 of the housing 3 through rol lers, gears, and the 1 ike. The wheels 13 passing along the rail 19 on the supporting plate 5 are installed under the lower end of the air suction plate 2. The air suction plate 2 is movably connected to the air compressor (turbo) 1 through wires or chains so as to be integrated into the air compressor (turbo) 1, so that friction on the rail 19 on the supporting plate 5 is minimized. A length of a part of the air suction plate 2 which is parallel with the air compressor (turbo) 1 (A//B) is the same as the length of the air compressor (turbo) (a=b).
As shown in FIGS.9, 10 and 11, in order to adjust the area of the air suction plate 2 that contacts wind based on a wind speed, the length of the air suction plate 2 constructed with two plates may be changed by sliding a plate over the other plate (FIG.9A). Selectively, the air suction plate 2 constructed with a plurality of plates may be opened or closed (FIG 9B). Selectively, the air suction plate 2 constructed with a single plate may be folded at the center of the air suction plate 2 (FIG. 9C).
FIG.6 illustrates an example of a flow of air in a case where an air compressor (turbo) 1 is located at a front side of wind. In order to prevent rotation of the rotor 4 from being interrupted by air that rotates around the rotor 4 so as to obtain optimal efficiency of power generation, even at a low wind speed, the air suction plate 2 is installed. Accordingly, the rotation speed of the rotor 4 is increased by dispersing the air to the back of the air suction plate 2, thereby increasing torque.
FIG. 7 illustrates an example of position changes of an air compressor (turbo) and an air suction plate, in a case where a wind direction is changed. It is possible to improve power generation efficiency, since power consumption used for moving the air compressor (turbo) 1 so as to move the air compressor (turbo) 1 to the front side of wind based on a changed wind direction, when a wind direction is changed, by driving a motor 11 lying over the housing 3 is reduced by using force of wind colliding against the air suction plate 2. [Industrial Applicability]
As described above, in the present invention, the air suction plate 2 is combined in a conventional wind power system, thereby increasing rotational power of the rotor 4. In addition, since power consumption used for moving the air compressor (turbo) 1 by driving the motor 11 lying over the housing 3, so that the air compressor (turbo) 1 is located at the front side of a wind direction, is reduced, the power generation efficiency is improved. Accordingly, it is possible to efficiently generate power by using a wind power system according to an embodiment of the present invention.
