If the width of a structural boat is to be increased, a side boat will be added to the central boat to support the turbine. This will increase the buoyancy and strength of the entire structural boat.

除去装置が必要である。The mooring buoy used for the peripheral device of the boat with the power generation system and the bow of the boat with the power generation system for marine power generation has a rotating function because the stern changes according to the change in the flow of the marine current. Things are required. In particular, in the case of a boat with a power generation system used for tidal power generation, a removing device such as a net is necessary before and after the structural boat in order to remove driftwood and various drifting substances.

Since only the bow of the boat is anchored and fixed in the direction of the current, directly or through the mooring buoy and the moored boat, the stern of the boat moves freely according to the flow, and the boat always moves in the direction of the current. Since the head of the boat is pointed at the head, power can be generated using the hydrodynamic force of the ocean current. In sea areas where the current direction of the ocean current does not change significantly, the mooring buoy and the mooring boat are each stationary and fixed with direct anchors, and the power generation system structure boat is stationary and fixed with the mooring line with the mooring line facing the ocean current. In addition, since the periphery of the boat with the power generation system structure is directly stopped and fixed via an anchor or a mooring buoy, it is possible to generate power using the tidal and marine currents.

As shown in FIGS. 1 (a) and 1 (b), when the head of the boat with the power generation system is stationary and fixed by the anchor with the head of the boat facing the current direction, the flow force of the current causes
The impeller of the turbine receives the force of the flow velocity from the vertical direction, and the turbine rotates. The generator is driven by the rotational energy of the water turbine to generate power. The number of turbines and generators is determined by the total amount of power generation, and the location of the generators can be freely selected by changing the direction of rotation of the turbine from horizontal to vertical.

る。The impeller of a water turbine always keeps a constant water depth,
Power generation is possible if the current of the ocean current is at least 0.5 to 1 m per second. The current and power generation of the ocean current are expressed by the following formulas based on the momentum theory of hydraulics. F = ρAV 2 where, F: force N (Newtonian) [rho: density of seawater kg / m 3 V: flow velocity m / s A: area m 2 W slats hydraulic turbines: power generation Nm / s Thus, ocean current power generation In the case of, the density of seawater is 1,021k
and g / m 3, at a flow rate of ocean currents per 1 m (2 knots),
When the area of the impeller of the water turbine is 7 m 2 , the power generation is about 4 kW
(In the case where the efficiency is 60%), and as the flow velocity increases, it increases to twice the flow velocity. That is, a width of 70 m,
A power generation system boat with a length of 350 m and a water turbine of 25
When two units are installed, the power generation amount is about 1,080 kW when the flow rate of the ocean current is 1 m / s, and the flow rate is 2 m / s.
In this case, the power becomes about 4,320 kW. On the other hand, the amount of power generated by an underwater submersible turbine generator is calculated by the following equation. W = 1 / 2ρCpAV 3 where Cp is an output coefficient. If Cp = 0.35 is adopted in the present invention, 1.75K when the flow rate is 1 m (2 knots) per second and the area A is 10 m 2 .
w, 14 Kw at 2 m (4 knots) per second.
That is, 120 submersible turbine generators are installed in a power generation system structure boat having a width of 70 m and a length of 350 m, and the power generation amount is 210 Kw when the flow rate of the ocean current is 1 m per second.
In the case of a flow rate of 2 m / sec, it becomes 1,680 Kw. Therefore, the total amount of power generated by the blades used on the sea surface and generated by the submersible turbine generator used in the sea is 2 per flow rate per boat.
m is about 6,000 Kw. If 36 boats with a power generation system are placed in a 5km square sea area, the total power generation will be 216,000Kw, 1.5m at a flow rate of 2m / s (4 knots).
113,000Kw at (3 knots), 4 at 1m (2 knots)
It will be 66,000 Kw. Incidentally, the current of the Kuroshio varies slightly depending on the sea area and the season, but it is observed at 0.5 to 2 m throughout the year.

機は、その影響が少ない。The power generation system structure boat has a central boat and both side boats, which increases stability, increases the effect of preventing rolling and other swaying, and also increases the strength of the entire structure boat. 2. When used as ocean current power generation, it is convenient for the bow of the central boat to flow in the direction of the ocean current as a center fulcrum. 3. The structure of the boat is relatively simple, it can be built immediately according to the current technical level, and the scale can be adjusted according to the situation, so that it can be easily installed in all straits, coves and sea areas. 4. Unlike a semi-permanently fixed power generator, docking is possible, so maintenance and inspection and repair are easy. 5. Since it is built to float on the sea, the draft of the boat is kept constant and the water depth of the blades of the turbine is always constant even if the water level changes due to ebb and flow. 6. The fossil fuel-powered generator emits waste pollutants from the furnace, but this boat does not emit any pollutants and there is no danger. 7. Even if the power generation facility is removed for some reason, it is relatively easy. 8. The blade-type water turbine used on the sea surface is slightly
Although affected by waves, submersible turbine generators used underwater are less affected.
