Abstract

<P>PROBLEM TO BE SOLVED: To provide a means capable of efficiently turning a turbine by diffusing/distributing shocks of large waves, and a hull structure to avoid non-turn of the turbine by turning-in of waves around a stern part of a barge. <P>SOLUTION: On-going wave flow A is divided and elevated not only on a lower flow-in hole of a turbine but also over a cover block above the turbine to turn a (twin) turbine and to elevate a free water inclined stage, inverted by a wave-receiving free-water inversion block to be in-coming water flow, and re-flows onto upper stay of the (twin) turbine to enhance the rotational efficiency of the turbine. In addition, fluctuation and movement of the crest point of wave has time difference between the inner side and the outer side of a hull. A bottom plate and a stern plate of a rear part of the hull are built in a structure in which two or three stepped panels are alternately engaged with each other with intervals, preventing the turbine from being flooded with and immersed in waves by rapidly discharging water by a mans to return the turbine at the sea level so as to take time in advancement of the crest point of waves turning into the stern structure. <P>COPYRIGHT: (C)2005,JPO&NCIPI

TECHNICAL FIELD OF THE INVENTION
The present invention relates to the construction of an emergency evacuation port or the construction of a marine base for the development of seabed resources from the standpoint of preventing marine accidents caused by storm surges, storm surges, storm surges, etc.
[0002]
[Prior art]
There is little wave power generation using ships and barges on the sea, and there is no example of constructing an emergency evacuation port or marine base by eliminating wave swells on the sea.

[Problems to be solved by the invention]
(11) Patent application publication number, JP-A-2001-172950,
[0020]
As described in Drawing 2, the method in which the wave current flowing uphill on the inclined home stage flows in one direction only into the lower pit of the turbine is improved, and the large wave to the inflow block (36) (FIG. 5) is improved. It is an object of the present invention to disperse and divide a destructive impact force and to rotate a water turbine more efficiently by a condensate flow.
[0004]
[Means for solving the problem]
The wave current A (A), whose wave undulation rises steeply on the inclined platform stage, flows into the lower shaft (a) of the watercraft above the hull and gets the primary rotational force of the water turbine. ) The water flow D which rises upward, flows into the central turbine inflow pit (i) and divides into the water flow C which obtains the secondary rotational force of the turbine, and the rising water flow D is further raised by the flip-up plate (P) at the upper end (Q) of the block. It jumps once to become the water flow E, rises the spill stage by the surplus power of the water flow E, is inverted by the wave receiving and inversion block (R), and becomes the descending water flow F by the gravitational force, and becomes the descending water flow F. E) Re-flow to (O) to obtain the tertiary torque of the turbine. In addition, in order to make it possible to adjust the inclination angle of the water reversal block (R), the point S is a fulcrum, the point T is made up and down movable by a cylinder or the like, and the water flow D is passing through the point Q of the flip-up plate (P). Since the weight of the water flow is low and after passing in a closed state, the point Q jumps up, the weight of the balancer (L) is adjusted appropriately using the point O as a fulcrum according to the principle of the seesaw, and the water flow E and the reversing downward water flow F are all inflow into the upper shaft of the turbine. ) Is provided with an opening and closing device so that it can be adjusted according to the amount of idle water.
[0005]
In addition, twin turbines (two turbines)
In the case of FIG. 1) as well, the structure is such that the wave water force is converted into a more efficient and less lossy rotational force by the same description as above.
[0006]
The wave water A climbs up the inclined stage and goes up and down on the barge to rotate the water turbine by the outgoing water flow and the condensed water flow. After that, the water flow G is discharged and discharged to the rear of the barge. The height (β) of the barge from the sea surface is raised when the front of the barge is raised, so that the water flow A becomes weaker and the rotational force of the turbine decreases, but the discharge and discharge becomes sufficient and faster. A is stronger, and the rotational force increases, but the drainage is insufficient and slows down, resulting in a sinking state.
[0007]
Therefore, the height (β) (water flow A) at the front of the barge, the height (γ) (water flow H) at the rear of the barge, and the height (δ) of the top point at which the sea surface waves are displaced are compared. It is necessary to clarify the issues and devise countermeasures in demonstration tests, etc.The top point of sea surface waves is irregular and repetitive movement with a time lag, and the waves wrap around behind the barge and around the drain, An indispensable issue is a hull structure for avoiding a situation in which the rear portion of the water turbine cannot be rotated due to flooding and submersion due to rising water level due to reverse water flow (J).
[0008]
As a countermeasure 1 of the solution, the top and bottom of the waves are displaced and moved with a time difference between the inside and outside of the side wall of the hull structure. The ship bottom plate has a triangular prism (V, W) shape and has a bottom structure in which the bottom plate is alternately meshed with two faults and three faults with step panels at regular intervals.
Similarly, the rear panel of the stern has a two-fault and three-floor panel plate meshing shape, and the structure that causes a further time difference integrates and calms the drainage flow (H) and reverse water flow (J) with each other. A solution to return to sea level. In addition, the A type port which connects and connects the barge to the A type shape (
In the case of a barge having a long overall length, it is considered that the problem does not occur or is small.
[0010]
【The invention's effect】
The destructive impact force of the large wave is directly converted into the rotational force of the turbine, and the turbine is efficiently diverted up and down by the outgoing water flow and the condensed water flow.
