Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea concerns the structure and shape of the rotating blades of wind and hydraulic power generators. A variable blade structure that captures the movement energy of fluids such as wind, river water, and tidal seawater currents. The rotational kinetic energy of this machine is reduced by increasing and varying the receiving force area with the rotating blades. This is to increase the conversion efficiency of the Ru.

[Conventional technology]

Conventionally, the blade shapes of wind power generators are propeller type, multi-blade type, Savonius type, and Dariyu type. There are other types such as S type, but they have the following weaknesses. (b) Propeller type and multi-blade type are difficult to move fluids compared to the size of the facility. The area of the blade that receives energy is small, and it converts energy for use in power generation, etc. ineffective. Moreover, the structure itself has an eccentric center of gravity with respect to the vertical direction of the main axis. , which increases further in strong winds, so rotation must be stopped and stopped due to the risk of the main shaft breaking. It becomes an unavoidable situation. (b) The Savonius type and Darius type rotate due to the difference in resistance to the wind between the left and right blades. However, the projected area on the vertical plane is the same on both sides, resulting in poor energy conversion efficiency. stomach. (c) Conventionally, in the case of water turbines used for hydroelectric generators, due to the large scale of the facility. In comparison, the area that receives the moving energy of river water, etc. is small, and the energy change is small. Poor conversion efficiency. (d) The turbine type stores river water in large-scale facilities such as dams and stores it in high places. It is necessary to concentrate the moving energy of the fluid in a conduit, etc., and it is easy to Therefore, it is not suitable for small-scale power generation facilities.

[Issues that the invention attempts to solve]

The purpose of this invention is to increase the efficiency of wind and hydroelectric power generation, and to utilize the moving energy of fluids. - There is a contradiction between when the entire surface of the blade receives the resistance and when the resistance is reduced by changing the direction of the blade. A single blade with many functions and smooth and stable rotation with no eccentric center of gravity. , a variable blade type that takes into consideration energy reception efficiency and body safety, and the structure and shape of the rotating blade. The goal is to develop

[Means to solve the problem]

(b) Multiple horizontal axes 2 are placed at any position on the vertical axis 1, and angles are equally divided with respect to the horizontal plane. Spread it out and let it stick. (b) The rotary blade 3 is suspended so that it can rotate about the horizontal axis 2 as a fulcrum. Yo Therefore, the rotating blade 3 has a variable structure with respect to the horizontal axis 2. (c) When the force of the fluid is applied to the rotating blade 3, the vertical axis 1 A vane receiving rod 5 for transmitting force is arranged and fixed to the vertical shaft 1 in parallel to the horizontal shaft 2. (d) To prevent the rotating blade 3 from rotating too much to the opposite side of the blade receiving rod 5 due to momentum, A rising stopper 6 is fixed at an arbitrary position on the horizontal axis 2. (e) The rotary blade 3 is susceptible to the movement energy of the fluid, and the vertical axis 1 When rotated in the opposite direction around It is shaped like a plate or an airfoil to protect the material. (f) The vertical shaft 1 is held vertically and horizontally by the vertical bearing 7, and the vertical shaft 1 is It is pivoted to a fixed base 4 so that it can rotate freely. (G) The vertical axis 1 and the generator convert the moving energy of the fluid into rotational energy. The electric machine 8 is linked directly or by a shaft, gears, belt, etc. (h) In order to further stabilize the rotating body configured as described above, the rotating blades 3 There is also a method of fixing a disc-shaped flywheel at any position on the vertical shaft 1 that does not interfere with rotation. .

[0005]

[Effect]

Since the present invention has the above structure, the vertical axis 1 is rotated by the following mechanism. Turn around. (b) Although it is arbitrary to explain on a perspective view, the fluid moves in a certain direction. If the rotary vane 3 is in the (A) position, the moving energy of the fluid is The force is applied to the entire surface of the blade, and the force proportional to the area is transmitted to the blade support rod 5. The rotational energy of the vertical shaft 1 is converted into rotational energy by interlocking the fixed vertical shaft 1 with the vertical shaft 1. (b) When the rotary vane 3 comes to position (B), it is parallel to the moving direction of the fluid. Therefore, the resistance to the fluid is extremely reduced. (C) When the rotary blade 3 comes to position (C), the blade support rod 5 is moved by the fluid. Because it is located in front of the rotating blade 3 in the direction of rotation, the pushing force of the fluid The lower end of the rotary blade 3 springs up freely around the horizontal axis 2 to provide resistance to the fluid. is very small compared to state (a). (d) When the rotary vane 3 comes to position (D), the state will be the same as in (b) and the flow will be The resistance to the body is greatly reduced. As mentioned above, since the rotating blade has a variable blade structure, the resistance force against the fluid is Due to the large area of the rotating blade 3 and the large moving energy it receives, It can be efficiently converted into rotational kinetic energy. In addition, due to the characteristics of the structure of this blade, the horizontal A constant value that arbitrarily sets the movement energy of the fluid from all 360 degree directions. The vertical axis 1 can be rotated in the direction of. (e) A rotating body that has the same weight and shape on its front, rear, left and right sides around a horizontal axis. When rotating, the eccentricity of the center of gravity is extremely small and the rotation of the vertical axis 1 is smooth and safe using the principle of a top. Make it a fixed one.

【Example】

The present invention can be used as follows. (b) It has good energy conversion efficiency and can be made compact, making it suitable for small-scale private power generation. It can be easily installed in remote areas, remote islands, and areas with no electricity supply in the mountains. (b) By extending the vertical axis and increasing the number of rotary blades in multiple stages, one facility can be heated. The energy receiving area increases, efficiency increases, and scale can be expanded freely. Can be done. (c) Due to its high energy conversion efficiency and non-directional characteristics, the sails of sailing ships, etc. Instead, if you use the power generation system of this invention, you can control the direction of the sail as long as there is wind. Just like a ship with an engine installed, you can move the ship in any direction. Ru. (d) Due to the characteristics of the blade structure, it is difficult to absorb wind, river water, seawater currents such as tides, etc. It is compatible with a wide range of fluids in the natural world and has a wide range of applications. For example, when installing in a river, etc., even if they are arranged vertically in the direction of the flowing water, the positions are perpendicular. It has a wide range of applications as it can be used for both small and large facilities. In addition, due to its non-directional properties, it can handle flowing water in the forward and reverse directions, such as the ebb and flow of the tide. For example, when installed in structures such as breakwaters, clean natural energy can be generated on a large scale. You can use ghee.
