2. Description of the Related Art In conventional ship types, increasing the length and width of a ship to have a wide deck requires significant increases in the longitudinal and lateral strength of the ship. In particular, the increase in intensity becomes remarkable due to the influence of waves. Therefore, an increase in these strengths causes an increase in the size or number of members bearing each strength, resulting in an increase in the weight of the entire ship. An increase in the length and width of a ship means a significant increase in the resistance of the ship, which results in an increase in the power required for propulsion and also leads to an increase in the weight of the power plant.

On the other hand, an increase in the exposed deck raises the center of gravity of the ship, causing problems in the righting ability of the ship. For the above reasons, having a wide deck for solar energy utilization is a disadvantage if the conventional ship shape is used. Therefore, it will be difficult to realize the benefits of using solar energy without inventing new ship shapes.

[0006] Conventional ships have utilized fossil fuels, which are limited in quantity and pollute the environment, as an energy source for propulsion. Of course, there are some that use wind power and other forms of energy, but these are extremely rare.

To make full use of solar heat to power a ship, the seawater around the ship is filtered, the purified water is turned into a caustic soda electrolyte, and a high-pressure, high-temperature multi-electrode water electrolysis unit is used to generate hydrogen and oxygen gases. A fuel cell is created using hydrogen as fuel and oxygen as an oxidant. Hydrogen and oxygen are electrochemically reacted in this fuel cell, and the reaction energy is extracted as heat and electricity, and this electricity is used as an electric power source for ship propulsion. The energy will be used for the propulsion device, and the heat will be recycled as a heat source. When implementing this idea, the question is how much solar energy can be used for water electrolysis. The key to this is to increase the size of the ship's exposed deck to increase the solar heat absorption area. With conventional ship shapes, there is a limit to the size of a ship that can accommodate a wide deck as the length and width of the ship increases.

[0008]

[Problems to be Solved by the Invention] Increasing the length and width of a conventional ship in order to widen the exposed deck causes the following problems. (A) This results in an excessive increase in the weight of the ship above the waterline. (B) This forces the ship's center of gravity to rise, causing problems with the ship's righting performance. (C) It impairs the ship's turning ability. (D) The size of the existing shipyard slipway or beam precludes its use for new construction or repair.

[Function] (1) In the present invention, by dividing the hull into a floating body and a submerged body, the length and width ratio of the floating body can be reduced in order to obtain a large deck area, and at the same time, it is possible to take into account corrosion caused by seawater. This makes it possible to reduce the weight of the floating body by using a different lightweight material from that of the submerged body, and by adopting a lighter structure by mounting lightweight objects. Reducing the weight of the floating body suppresses the rise of the ship's center of gravity. By reducing the ratio of the length and width of the floating body and by connecting the floating body and the submerged body using support legs, the righting performance of the ship is extremely improved and speeding up is possible.

(2) In the conventional ship shape, the change in buoyancy acting on the hull due to waves is large, but in the hull shape of the multi-legged ship of the present invention, the change in buoyancy is extremely small. This is a reference diagram. In FIG. 5, for the area of the same exposed deck 1A shown by the chain line, the conventional ship type is shown in FIG. It will have an area. This represents the case of floating in still water. Figure 5 (A) shows the width (W) of the ship and the length (L) of the ship.
) is assumed to be 1/10. Figure 5(A),
Comparing FIG. 5(B), it can be seen that the hull form of the multi-legged boat of the present invention has extremely small waterline areas scattered throughout. Therefore, in the multi-legged boat of the present invention, the change in buoyancy acting on the legs due to the height of waves is extremely small, and the oscillation caused by waves is small.

(3) FIG. 6 is a diagram showing the case where the wavelength of the maximum wave on the service route is equal to L in the figure and trochoidal waves with a wave height of L/20 act on the hull form of the multi-legged ship of the present invention. be. Figure 6 (A) shows the case where the wave crest is at the center of the ship.
(B) shows the case where the crest of the wave is at the center of the front leg. What you can see by referring to this diagram is that the waves and the ship's hull are out of phase, with only a portion of the waves causing a change in buoyancy on the ship's legs, and the waves acting on them are out of phase. If FIGS. 5 and 6 are considered together, it becomes clear that the multi-legged boat according to the present invention exhibits extremely small changes in the buoyancy force acting on the legs due to waves. This means that the multi-legged boat of the present invention suffers extremely little oscillation due to the shape of the boat.

(4) With conventional ship shapes, if the length and width of the ship increase, the turning performance of the ship will deteriorate. In the multi-legged ship of the present invention, the injection channels T1 W1 shown in the sectional view of the submerged main body in FIG. It will be steered by. If the front and rear water are ejected in the same direction, the ship's drifting force will be obtained, and if they are directed in opposite directions, the ship's turning force will be obtained. Therefore, by providing this injection channel at the front and rear of the ship, the turning performance of the ship can be improved.

(5) The dimensions of the multi-legged ship of the present invention are expected to far exceed the scale of existing large-scale shipyard docks or docks. Therefore, it is necessary to install, assemble, and repair the equipment offshore or on the outfitting quay. For this purpose, if the floating body and connecting legs, and the floating body and supporting legs are constructed to be detachable, the floating body, connecting legs, submerged body, and supporting legs can be separated and installed offshore or on an outfitted quay. Installation, assembly, and repair can be made easier.
