The windmill 30 is, for example, a horizontal axis propeller type including six rotary blades. Further, the pitch of the rotor blades of the windmill 30 can be changed as necessary. In addition, the shape of this windmill 30 is not restricted to this example, The number and shape of a rotary blade can be changed as needed.

  The generator 40 is connected to the rotating shaft of the windmill 30 and generates electric power with the rotational driving force of the windmill 30. The generator 40 can use an AC generator or a DC generator. The generator 40 selects an appropriate generator according to the rotational driving force of the windmill 30.

  The generator 40 is disposed on the support 20 via the rotation drive device 60. The rotational drive device 60 can rotate the windmill 30 360 degrees around the axis of the support column 20, and directs the windmill 30 to a position where the wind efficiency is high. That is, the axis of the windmill 30 is arranged so as to be parallel to the wind.

  Here, the height of the support 20, the size of the windmill 30, and the power generation capacity of the generator 40 need to be selected according to the size of the hull. If the windmill 30 is too large for the hull 10, the stability of the hull 10 is impaired.

  The windmill 30 is provided with a guard case 50 that covers the windmill 30. The guard case 50 is formed by combining, for example, metal wires, for example, stainless steel wires, in a net shape. The guard case 50 prevents a bird or a foreign object blown by the wind from entering and colliding with the windmill 30. The guard case 50 is not limited to metal but can be made of synthetic resin.

  A power storage device 70 that stores electrical energy from the generator 40 is provided in the hull 10. The power storage device 70 includes a secondary battery such as a lead storage battery, a lithium ion battery, or a nickel metal hydride battery. The type of secondary battery is selected in consideration of the cost, the power generation capacity of the power generator, the size of the hull, and the like. In the case where an AC generator is used as the generator, a rectifier that directs the power input to the secondary battery is disposed in the power storage device 70.

  Further, the hull 10 is provided with a power delivery device 80 that sends the power from the power storage device 70 to the outside. The power transmitted from the power distribution device 80 can be output to a transmission device 81 arranged on the deck of the hull 10.

  Further, the hull 10 includes a propulsion device 90 that operates the hull 10. As propulsion device 90, an electric motor that uses electric power from power storage device 70 can be used in addition to an internal combustion engine and an external combustion engine. A screw 91 is connected to the propulsion device 90. In the figure, reference numeral 92 indicates a rudder for controlling the traveling direction of the hull 10.

  Further, the hull 10 is provided with a anchoring device 110 for restricting the movement of the hull 10. The anchoring device 110 throws or raises the anchor 111 connected to the anchor chain 112.

FIG. 2 is a block diagram showing a configuration of the ship-type wind power generator, and FIG. 3 is a schematic diagram showing an operational state of the ship-type wind power generator. In the boat-type wind power generator 130, the wind turbine 30, the generator 40, the rotation drive device 60, the power distribution device 80, and the propulsion device 90 are controlled by the control device 120 as shown in FIG. The control device 120 controls each unit by processing software with a computer including a CPU, a RAM, a ROM, a display device, an input device, and the like.

  The control device 120 performs pitch control of the rotor blades of the windmill 30, control of the direction of the windmill by the rotation driving device 60, and output control of the power distribution device 80. Further, the propulsion device 90 can be controlled.

  As shown in FIG. 3, the ship-type wind power generator 130 generates power in a predetermined power generation region 300 and stores predetermined power in the power storage device 70. At this time, the direction of the wind turbine 30 is adjusted so as to be the most efficient with respect to the wind under the control of the control device 120.

  It is desirable that the power generation area 300 is an area where the wind suitable for power generation is stably blowing near the base 200. If the power generation area is away from the shore, damage caused by low frequencies due to the rotation of the windmill can be prevented. After storing a predetermined amount of power in the power storage device 70, the ship-type wind power generator 130 returns to the base 200 and anchors.

The power transmission facility 210 receives, for example, power from the ship-type wind power generator 130 and stores the power storage facility 211, and converts the DC power stored in the power storage facility 211 into alternating current of a predetermined frequency and voltage, and transmits a power line 213 for power transmission. And substation equipment 212 to be sent out.

  The power stored in the power storage device 70 of the ship-type wind power generator 130 is sent to the power storage equipment 211 of the base 200 through the power distribution device 80 and the sending device 81 under the control of the control device 120. The ship-type wind power generator 130 releases the power of the power storage device 70 and then moves to the power generation region 300 again to generate wind power. The ship-type wind power generator 130 performs power generation and power transmission between the power generation area 300 and the base 200.

  In the base 200, the DC power of the power storage equipment 211 is converted into AC having a predetermined frequency and voltage by the substation equipment 212 and transmitted from the power line 213.

  The boat-type wind power generator 130 according to Embodiment 1 has the following effects. In other words, the windmill can be protected by the guard case, the windmill can be prevented from being damaged by flying foreign matter, and the power generation efficiency of wind power generation on the ocean can be increased. In addition, this electric energy can be delivered from the base.

  Since a plurality of wind turbines and generators are provided, high power generation can be realized. Furthermore, by throwing, the movement of the hull can be restricted, and the reduction in power generation efficiency due to the movement of the hull and the occurrence of contact accidents with other ships can be prevented. Since the propulsion device is provided, the hull can be moved to the surface of the water surface, more specifically to a point where strong wind power on the sea can exert high power generation, and can reciprocate between bases as necessary.
