Next, the operation of the above-configured surface power generation ship 100 will be described.
In the above-described hydroelectric power ship 100 according to the present embodiment, when wind is generated, the spiral rotary blade 53 of the rotary blade 5 receives the wind and rotates around the mast portion 2 around the axis O. When the spiral rotary blade 53 starts to rotate, the upper disk portion 541a and the lower disk portion 542a formed integrally with the spiral rotary blade 53 also start to rotate. When the lower disk part 542a of the lower rotation fixing part 542 rotates, the transmission gear 611 of the power generation unit 6 that meshes with the lower disk part 542a having a spur gear shape also rotates. Then, when the transmission rotation shaft portion 612 formed integrally with the transmission gear 611 rotates, the rotation shaft of the power generation section main body 62 that is the power generation section 6 rotates and the rotational power of the spiral rotor 53 is transmitted. The power generation unit 6 generates power. The electricity generated by the power generation unit main body 62 of the power generation unit 6 is supplied to and stored in the power storage unit 7. The solar power generation unit 10 also receives sunlight to generate power, and the generated electricity is supplied to the power storage unit 7.

Further, when wind is generated, the sail portion 4 receives wind as well as the spiral rotor 53, so that the hull 1 starts to travel along the wind direction on the water. At this time, the power storage unit 7 becomes a weight, and the hull 1 travels on the water while maintaining a stable posture with respect to the water surface. Further, the floating power ship 100 advances while adjusting the amount of wind received by changing the direction of the sail part 4 by rotating the first boom part 3 around the mast part 2 around the axis O. Further, as shown in FIG. 2, the surface power generation ship 100 is proceeding on the water while the float portion 9 connected to the other end of the second boom main body portion 81 of the second boom portion 8 is floated on the water surface. .
Further, when the wind direction changes and the direction of the hull 1 is likely to change due to the wind, the force received from the water is adjusted by changing the length and width of the center board 110 protruding from the hull 1 in water. In this way, the hull 1 prevents the hull 1 from flowing laterally by the wind by the center board 110 or changes the traveling direction of the hull 1.

  According to the above-described hydroelectric power ship 100, the spiral rotor blade 53 that is formed in a spiral shape so that the rotor blade 5 that rotates by receiving wind is twisted around the axis O as it goes up and down the mast portion 2. Therefore, the rotary blade 5 can be provided so as to extend along the mast portion 2. That is, while the rotor blade 5 is provided so as to extend along the mast portion 2, the rotor blade 5 is a spiral rotor blade 53 having a spiral shape, and therefore receives wind along the vertical direction of the mast portion 2. A large area can be formed. That is, the rotor blades 5 that efficiently receive wind and rotate can be formed along the mast portion 2. Therefore, even if the wind speed is low, the spiral rotor 53 that is the rotor 5 can be rotated by using the wind to the maximum. As the rotational speed of the spiral rotor 53, which is the rotor 5, increases, the rotational power transmitted to the power generator 6 also increases, and the amount of electricity generated by the power generator main body 62 of the power generator 6 also increases. To do. As a result, it is possible to increase the amount of power generated by the wind while saving space to such an extent that it can be installed in a limited space on the deck of the hull 1.

  Further, since the rotor blade 5 is formed in a spiral shape around the mast portion 2 along the axis O of the mast portion 2, it is possible to receive wind without being influenced by the wind direction. Therefore, the rotor 5 can be rotated in response to winds blown from various directions, and the spiral rotor 53 that is the rotor 5 can be stably rotated, and a stable power generation amount can be ensured. Become.

  Furthermore, by providing the hull 1 that travels on the water by receiving wind at the sail portion 4, the spiral rotor 53 that is the rotor blade 5 is provided, so that the hull 1 is advanced while the spiral rotor 53 is rotated by the wind. You can receive wind with higher wind speed. By receiving wind with a high wind speed, the number of revolutions of the spiral rotor 53 can be increased. Thereby, the rotational power transmitted to the power generation unit 6 can be improved, and the amount of power generated by the power generation unit 6 can be further increased.

  Further, while the floating power generation ship 100 is traveling on the water, the hull 1 travels on the water while the float 9 connected to the other end of the second boom body 81 that is the second boom 8 floats on the water surface. Thus, the buoyancy generated in the float portion 9 that is floating can be transmitted to the second boom portion 8. Specifically, when the hull 1 tilts and tilts so that the tip of the second boom portion 8 approaches the water surface, the float portion 9 is pushed into the water. Then, the float part 9 receives the buoyancy from the water surface and is pushed back upward. And since the 2nd boom part 8 is also pushed back upwards with the float part 9, it becomes possible for the 2nd boom part 8 to always maintain a horizontal attitude | position. Therefore, the mast portion 2 that supports the second boom portion 8 is in a vertical posture, and the rotor blades 5 attached to the mast portion 2 can also maintain a stable posture. Thereby, the spiral rotary blade 53 which is the rotary blade 5 attached to the mast part 2 can receive wind stably, and it becomes possible to ensure a stable power generation amount.

  Furthermore, even on days when the wind is weak and sufficient wind power cannot be generated, the solar power generation unit 10 can also generate power, so that the lack of power generation can be compensated for each other, and a more stable power generation can be secured. It becomes possible.

  Moreover, since the power storage unit 7 is fixed near the center of gravity of the hull 1, the power storage unit 7 can serve as a weight, and the hull 1 can be stabilized horizontally with respect to the water surface.

  Furthermore, since the center board 110 can change the length direction and the width direction, the center of gravity of the hull 1 and the force received from the water can be adjusted according to the wind direction and the air volume, thereby stabilizing the hull 1. Can continue to progress. Therefore, by continuing to advance the hull 1 stably, the spiral rotor 53 which is the rotor 5 attached to the mast portion 2 can receive the wind more stably and secure a more stable power generation amount. It becomes possible.

  Although the embodiments of the present invention have been described in detail with reference to the drawings, the configurations and combinations of the embodiments in the embodiments are examples, and the addition and omission of configurations are within the scope not departing from the gist of the present invention. , Substitutions, and other changes are possible. Further, the present invention is not limited by the embodiments, and is limited only by the scope of the claims.

The shape of the spiral rotor 53 that is the rotor 5 is not limited to the shape of the present embodiment. For example, a plurality of spiral rotors 53 are formed in the mast portion 2 so as to be interrupted in part in the vertical direction. It may be arranged along.
Further, the hull 1 is not limited to only having a structure that travels by receiving wind. For example, the hull 1 also has a motor or the like and travels on the water using electricity generated by the power generation unit 6. It may be 1.
