2. Description of the Related Art In conventional ship types, an increase in the length and width of a ship due to having a wide deck requires a significant increase in longitudinal strength and lateral strength of the ship. In particular, the influence of waves makes the necessity of increasing the strength remarkable. Therefore, the necessity of increasing these strengths leads to an increase in the size or the number of members that bear 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 an increase in the weight of the power unit.

On the other hand, an increase in the exposed deck promotes an increase in the center of gravity of the ship, which causes a problem in the stability of the ship. For the above reasons, wide decks for utilizing solar energy are disadvantageous if the conventional ship form is used. Therefore, it is difficult to bring out the merits of utilizing solar energy without inventing a new hull form.

[0006] Conventional ships have used fossil fuels, which are considered to be finite in quantity and have high environmental pollution, as an energy source for propulsion. Of course, there are some that use wind power and other energy, but this is extremely small.

In order to fully utilize solar heat as power for a ship, seawater around the ship is filtered, purified water is used as caustic soda electrolyte, and hydrogen gas and oxygen gas are supplied in a high-pressure high-heat multipolar water electrolysis unit. It is generated and sent to a fuel cell using hydrogen as a fuel and oxygen as an oxidant. In this fuel cell, hydrogen and oxygen are electrochemically reacted and the reaction energy is taken out as heat and electricity, and this electricity is used for electric propulsion of ships. Energy is used for the propulsion device, and heat is recycled as a heat source.
When implementing this idea, how much solar energy is used for electrolysis of water becomes a problem. To this end, the key is to increase the exposed deck of the ship to increase the solar heat absorption area. With conventional ship types, there is a limit to the size of wide decks that can be obtained by increasing the length and width of the ship.

[0008]

However, the following problems occur in increasing the length and width of a conventional ship to widen the exposed deck. (A) It causes an excessive increase in the weight of the upper hull of the water-drain line. (B) The center of gravity of the ship is forced to rise, which causes a problem in the stability performance of the ship. (C) The turning ability of the ship is deteriorated. (D) Utilization of an existing shipyard bed or dock for new construction or repair becomes impossible.

[0028]

In the present invention, the reason for adopting a special ship structure called a wide deck multi-legged ship is as follows. (1) Relationship between hull form and waves Conventionally, a ship is a hollow hollow body that floats on the sea while sailing while balancing the gravity of the ship and the buoyancy of water that the ship eliminates. This is called a monohull type or a conventional type (with the exception of hydrofoils and hovercraft). The ship has been constructed by determining the stresses given to the hull by self-propelled waves and ocean waves from the outside, considering the restrictions on the length, width and depth of the ship. Generally speaking, the ship form often means the form of a ship that comes into contact with water for discussing the resistance of the ship, but the ship form here means the form of the ship as a whole. The ship type of the wide deck multi-legged ship of the present invention is, of course, self-propelled waves, and the effect of ocean waves can be neglected so that the length of the ship is as long as desired, and a wider ship can be obtained. It is the basic form of the ship.

(2) A catamaran is a combination of two monohulls in a superstructure, and it is no different from a monohull in being affected by waves, and therefore its length and width are limited. It is no wonder that receiving is. Therefore, the expansion of the exposed deck by catamaran must be restricted accordingly.
In this sense, the increase in the exposed deck area using the catamaran type can be expected to be several times, but the order of magnitude is not expected. When the hull form of the present invention is adopted, it is considered that the length and width are several tens of US to several thousand US, and it is considered that it can be used for an airfield floating in the sea, a helipad or a marine base work ship near the equator. . The basic concept of the present invention is to use solar thermal energy to create hot air, generate power using the temperature difference between this hot air and cold seawater, and use this generated power to electrolyze water and hydrogen. It produces oxygen and oxygen, supplies it to a fuel cell to obtain electric power, and supplies electric power to drive a propulsion device. It attempts to use solar energy to self-sufficiently supply electric power. Since it is known as Japanese Patent Publication No. 2-1989 as an ocean temperature difference power generator, it is sufficient to use solar heat as a high heat source and cold seawater as a low heat source to generate electricity. Any suitable one attached to the water electrolysis unit may be used.

【The invention's effect】

(1) In the present invention, by dividing the hull into a levitation body and a submerged body, the levitation body can have a small length / width ratio for obtaining a large deck area, and at the same time can be corroded by seawater. It is not necessary to consider it, and it is possible to reduce the weight of the levitation body by adopting a lightweight material different from that of the submerged body and adopting a light structure by mounting a lightweight object. Reducing the weight of the levitation body will prevent the center of gravity of the ship from rising. The reduction of the length-width ratio of the levitation body and the connection of the support legs to the levitation body greatly improve the stability of the ship.

(2) In the conventional hull form, the change in the buoyancy acting on the hull of waves is large, whereas in the hull form of the multi-legged ship of the present invention, it is extremely small. FIG. 5 and FIG. 6 are reference diagrams for explaining this diagrammatically. In FIG. 5, the conventional ship type is shown in FIG. 5 (A) for the area of the same exposed deck 1A indicated by the chain line.
The hull form of the present invention has a waterline area of a shaded portion as shown in FIG. 5 (B). This represents the case of floating in still water. Figure 5 (A) shows the width of the ship (B) and the length of the ship (L)
It is a figure at the time of assuming 1/10 of. 5 (A) and FIG.
Comparing (B), it can be seen that in the boat form of the multi-legged ship of the present invention, extremely small waterline areas are scattered. Therefore, the multi-legged ship of the present invention shows that the change in the buoyancy acting on the legs due to the height of the wave is extremely small, and the fluctuation due to the wave is small.

(3) FIG. 6 is a diagram showing a case where a trochoidal wave having a maximum wave length of the service route equal to L in the figure and a wave height of L / 20 acts on the hull form of the multi-legged ship of the present invention. is there. Fig. 6 (A) shows the case where the crest comes to the center of the ship.
(B) shows the case where the crest comes to the center of the front leg.
It can be seen with reference to this figure that the wave and the hull are such that only a part of the wave causes a change in buoyancy on the legs of the ship and the phase of the acting wave is out of phase. 5 and 6 together, it becomes clear that in the multi-legged hull form of the present invention, the change in buoyancy acting on the legs due to waves is extremely small. This means that the hull form of the multi-legged ship of the present invention has very little sway due to waves.

(4) If the length and width of the conventional ship are increased, the turning performance of the ship will deteriorate. FIG. 4 shows the multi-legged ship of the present invention.
The water spray passage 21 shown in the cross section of the submersible body is provided at the front part and the rear part of the submersible body, and the steering action is performed by the reaction force of the water spray by the water spray device installed at the center of the submersible body. If the front and rear water sprays are made in the same direction, the drifting of the ship can be obtained,
In the opposite direction, the ship can turn. Therefore, the turning performance of the ship can be improved by providing this water jet passage in front of and behind the ship.

(5) The dimensions of the multi-legged ship of the present invention are believed to be much larger than the size of the bed or dock of an existing large-scale shipyard. Therefore, it is necessary to install, assemble and repair on the sea or on the outfitting quay. For this purpose, the levitating body and connecting legs,
If the levitating body and the support legs are detachable, the levitating body, connecting legs and submerged body, and supporting legs can be separated from each other to facilitate installation, assembly, and repair on the ocean or on the outfitting quay when necessary. Can be
