Wind power generators are divided into a horizontal generator and a vertical generator according to the direction in which the rotation axis of the blade is placed. The vertical axis wind power generator has a disadvantage in that it occupies a larger area than the horizontal axis. However, in the horizontal axis wind generators, the blades are horizontally stretched, so the blades may be drooped downward by gravity. In order to prevent sag of the wing, there is a problem in that a material having high strength and hardness is required in manufacturing a horizontal axis wind generator.

An example of a vertical axis generator is a multi-layer turbine that rotates at low speed with a convex vane around the column. Multilayer turbines do not have the disadvantages of horizontal generators and operate independently of the wind direction.

On the other hand, the ship wind generator is to be used for the main power of the ship. At this time, a lot of air resistance is received by the wind generator, there is a problem that the speed of the vessel is lowered. In addition, the ship's hull requires an additional reinforcement to support the large wind generator, and the total weight of the ship increases by the weight of the added reinforcement and the wind generator, so that the ship's ship speed before the wind generator is mounted on the ship The problem is that it is difficult to maintain.

The blade 10 connected to the shaft 12 generates power by rotating about the shaft 12 when the wind blows regardless of the direction of the wind. The blade 10 is made of a flexible composite material can be stretched or shrunk. For example, the blade 10 may be a synthetic high molecular compound such as polyurethane.

The blade 10 is connected to an upper portion of the shaft 12 and a lower portion of the cylinder 14 and spreads in a horizontal direction with respect to the shaft 12 vertically formed according to the vertical movement of the shaft 12. It may be folded and in close contact with the shaft 12. That is, when the shaft 12 is raised, the blade 10 is in close contact with the shaft 12. At this time, the blade 10 does not rotate even when the wind blows.

On the other side, when the blade 10 is in close contact with the shaft 12 and folded, the moving means such as a vessel provided with the blade 10 is not subjected to air resistance by the blade 10. Therefore, a moving means such as a ship provided with the blade 10 according to the embodiment of the present invention can avoid the air resistance that can be generated by the blade 10. Therefore, the movement means can avoid the phenomenon that the movement speed by the blade 10 falls.

The piston 20 is located below the shaft 12 and may be provided in the cylinder 14.

The cylinder 14 is supplied with hydraulic oil through the hydraulic controller 30. The piston 20 is moved up and down in accordance with the amount of hydraulic oil located in the cylinder 14.

The hydraulic controller 30 may control the amount of hydraulic oil inside the cylinder 14. Specifically, the hydraulic controller 30 receives the hydraulic oil supplied from the accumulator 50 or the oil tank 60 and injects it into the cylinder 14 or removes the hydraulic oil inside the cylinder 14 to accumulate the accumulator 50. Alternatively, by moving to the oil tank 60, the amount of hydraulic oil in the cylinder 14 can be controlled.

When the main generator (not shown) that produces energy by diesel or other energy sources is in normal operation, that is, when the vertical axis wind turbine 100 is not operating, the hydraulic controller 30 may accumulate the accumulator 50 or oil. Hydraulic oil stored in the tank 60 is injected into the cylinder 14.

At this time, the hydraulic oil stored in the accumulator 50 is supplied to the auxiliary generator 40. The hydraulic oil supplied to the auxiliary generator 40 rotates the gear and the hydraulic motor constituting the auxiliary generator 40. Power generated through the rotation of the hydraulic motor and the gear may be used for the initial rotation of the blade 10. That is, the auxiliary generator 40 may provide power required for initial rotation of the blade 10.

The accumulator 50 is an accumulator that maintains a certain amount of oil at a high pressure, and may be connected to the cylinder 14 through the hydraulic controller 30. In addition, the accumulator 50 may be connected to the auxiliary generator 40 through the hydraulic controller 30 for the initial operation of the blade 10.

Oil tank 60 stores hydraulic oil.

The battery 70 may temporarily store electric power generated by the main generator or the auxiliary generator 40 and supply the oil to the oil tank 60.

The oil tank 60 may receive the electric power supplied from the battery 70 and supply the stored hydraulic oil 30 to the accumulator 50 or the cylinder 14 through the hydraulic controller 30.

The pump 80 supplies pressure to the accumulator 50 to provide hydraulic oil to the accumulator 50. If sufficient pressure is not formed in the accumulator 50 through the pump 80, the hydraulic oil stored in the oil tank 60 may be manually supplied to the accumulator 50 using a hand pump (not shown).

The blade 10 supplied with the power required for the initial rotation through the auxiliary generator 40 continuously rotates by wind, and the auxiliary generator 40 may generate power based on the rotation of the blade 10. At this time, the hydraulic oil supplied to the auxiliary generator 40 for the initial operation of the blade 10 in the accumulator 50 is no longer supplied.

However, the hydraulic controller 30 may control the injection or removal of the hydraulic oil in the cylinder 14 to adjust the degree of flaring of the blade 10.

 4A to 4C are front, plan and side views of a vessel provided with a vertical axis wind turbine generator according to an embodiment of the present invention.

When the operation of the main generator (not shown) is stopped (S507), the hydraulic controller 30 removes hydraulic oil from the hydraulic cylinder 14 (S509). When the operation of the main generator (not shown) is maintained, the hydraulic controller 30 keeps the hydraulic oil injected into the hydraulic cylinder 14.

When the hydraulic oil is removed, the piston 20 is lowered (S511). As the piston 20 descends, the blade 10 connected to the upper portion of the shaft 12 descends along with the shaft 12 and spreads in a horizontal direction (S513).

When the blade 10 is opened, the hydraulic controller 30 supplies hydraulic oil stored in the accumulator 50 to the auxiliary generator 40 to drive the blade 10 (S515). The auxiliary generator 40 may rotate the gear through the supplied hydraulic oil and generate power by using a motor. Power generated by power generation is used for the initial rotation operation of the blade 10 in the horizontal direction (S517).

The hydraulic controller 30 may adjust the amount of hydraulic oil in the hydraulic cylinder 14 according to the wind strength (S519). As the amount of hydraulic oil increases and decreases, the shaft 12 can move up and down, and as the shaft 12 moves up and down, the blade 10 is stretched vertically and folded or unfolded horizontally.
