Ocean current and wind power generation device

Abstract

To provide a vertical axis power generation system which has a simple structure, low installation cost, is easy to maintain, and can be used for a large scale. [Solution] A blade rotating shaft (13) is attached to a bearing (8), and blades (14) are attached to the blade rotating shaft (13). There is an air tank inside the blade, and the volume of the blade is lighter than seawater, so it always faces upward due to buoyancy. The blades are arranged radially on the rotating shaft (5), and when the blades are hit by an ocean current, they stop at the support plate (11) and absorb the force of the ocean current, and the blades rotating against the ocean current fall down, reducing resistance and causing the rotating shaft (5) to rotate.

Description

[Technical Field]

[0001] [Background technology]

[0002] Solar panels and horizontal axis wind turbines are the mainstream methods of generating electricity using renewable energy. Currently, there are few other large-scale power generation devices that use renewable energy. [Prior art documents]

[0003] [Patent Document 1] Patent 7290896 Summary of the Invention [Problem to be solved by the invention]

[0004] There are no large-scale vertical axis wind turbines like there are horizontal axis wind turbines. Horizontal axis wind turbines are expensive to install and maintain. [Means for solving the problem]

[0005] We offer vertical axis power generation systems that are simple in structure, have low installation costs, and are easy to maintain, and can be used on a large scale. By utilizing ocean currents in the Seto Inland Sea, for example, stable power can be expected. Vertical axis power generation systems have a simple structure that allows them to rotate even in a light breeze. [Effects of the Invention]

[0006] Even if the wings are large, they are light and can generate electricity with a small amount of energy because they use air and helium gas for their weight. [Brief explanation of the drawings]

[0007] [Figure 1]Front view Raft 1 is thick enough to withstand changes in sea level, and is fixed to the seabed with fixing wires 2. Attached to raft 1 is a bearing holder 3 with a bearing 4 inserted into it, and a rotating shaft 5 is inserted into it so that it can rotate freely. A rotating plate 6 is fixed to the rotating shaft 5 with a rotating plate fixing bracket 7, and a bearing 8 and a fixing plate 9 are attached to the rotating plate 6, and a support 10 is attached to the rotating plate 6, with a support plate 11 set on top of that. A blade rotating shaft 13 is attached to bearing 8, and blades 14 are attached to the blade rotating shaft 13, allowing the blades 14 to rotate freely. When the blades 14 are exposed to an ocean current, they stop against the support plate 11 and absorb the current. The blades 14, which rotate against the current, tilt down, reducing resistance and allowing the rotating shaft 5 to rotate. A thrust bearing 15 is mounted on the bearing holder 3, and a gear 16 is attached to the rotating shaft 5. Gear 16 engages with gear 17, which rotates a generator 19 via a transmission 18. The generator 19 is fixed to the raft 1 with a generator fixing block 20.

[0008] [Figure 2] AA Plan View This diagram shows blades 14 attached radially to a rotating shaft 5, and shows the movement of the blades 14 due to ocean currents.

[0009] [Figure 3] BB cross section This is a drawing of the wing 14 supported by the support plate 11 under the force of the ocean current. Inside the wing 14 there is space for the air tank 23, and the volume of the wing 14 is lighter than the specific gravity of seawater, so that the wing 14 always faces upward.

[0010] [Figure 4] CC cross section This is a diagram of the wings 14 tilting down to reduce resistance when heading into the ocean current. The amount of tilt can be adjusted using the control rope 24.

[0011] [Figure 5]Front View D: A foundation block 27 is placed on the ground, and a bearing holder 28 with a bearing 30 inserted into it is attached on top of it, and a rotating shaft 31 is placed inside so that it can rotate freely. A thrust bearing 32 is attached on top of the bearing holder 28, and a gear 33 is attached to the rotating shaft 31. Gear 34 meshes with gear 33 and drives a generator 36 via a transmission 35. The generator is fixed to the foundation block 27 with a generator mounting block 37. A rotating plate 40 is fixed to the rotating shaft 31 above the gear 33 with a rotating plate fixing bracket 41. A bearing 42 and a fixing plate 43 are attached to the rotating plate 40, and a support 44 is attached to the rotating plate 40, and a support plate 45 is set on top of that. A blade rotating shaft 46 is attached to the bearing 42, and the blade rotating shaft 46 has blades 47 attached to it so that the blades 47 can rotate freely. When the blades 47 catch wind, they stop against the support plate 45 and catch the wind. The blades 47 rotating against the wind fall down to reduce resistance, allowing the rotating shaft 31 to rotate.

[0012] [Figure 6] EE Plan View This diagram shows blades 47 attached radially to a rotating shaft 31, and the movement of the blades 47 due to wind.

[0013] [Figure 7] FF cross section This is a drawing of the wing 47 supported by the support plate 45 under the force of the wind. There is space for a helium gas tank 48 inside the wing 47, and the volume of the wing 47 is lighter than the specific gravity of air, so the wing 47 is always set facing upward. There is no particular specification for gases lighter than the atmosphere other than helium gas.

[0014] [Figure 8] GG Cross Section This diagram shows how the wing 47 is tilted to reduce resistance when heading into the wind. The amount of tilt can be adjusted using the control rope 49. DETAILED DESCRIPTION OF THE INVENTION

[0015] When using ocean currents, it is best to use it in an area where the currents change drastically, such as the Seto Inland Sea.When using wind power, it is best to use it in an area where the wind blows well throughout the year, and the wings need to be folded down when a typhoon approaches. [Industrial Applicability]

[0016] The cost of installation and maintenance is low, the structure is simple, and it can be made large, making it suitable for commercial use. [Explanation of symbols]
