摘要： PURPOSE:To improve the stability of a floating body and improve the wave energy absorption performance by arranging an accessory facility fitted with various facilities such as a pool on a pontoon at the rear section of a marine structure main body. CONSTITUTION:An accessory facility 10 fitted with various facilities such as a pool 12 and a rest house 13 and a power distribution panel room 15 feeding the electric power required for these facilities on a pontoon 11 is integrally arranged at the rear section of a marine structure main body 4. Since the pontoon 11 is arranged at the rear section of the marine structure main body 4, the whole length of the structure is extended, and the stability as a floating body can be improved. It can be utilized as an island floating on the sea by utilizing various facilities such as the pool 12, people and goods can be transported by a helicopter by utilizing a heliport 14, and this structure can be effectively utilized even when it is moored apart from the seashore. The structure has little sway due to waves, thus the wave energy absorption performance can be improved, and the electric power required for various facilities of the accessory facility 10 can be fed.

CONSTITUTION:An air chamber 3 extending in a laterally long manner is formed to the front part of a floating body 1 having a floating chamber 2, and a sea water flow entrance opening part 5 is laterally formed in the lower front part of the air chamber 3. An upper front part 1a of the air chamber 3 is formed in a rounded shape forming a gentle streamlined type. Further, an air hole 6 is formed in a ceiling part, through compression of air in the air chamber 3 by means of sea water flowing through the sea water flow entrance opening 5, air is discharged upward through the air hole 6, and operation to absorb wave energy is carried out. The proper number of buoyant tanks 8 is mounted on the rear end part of the slope plate 4, and mooring is effected by means of mooring cables 9 tied to the front end part of the floating body 1 and the rear end part of the slope plate 4.

摘要： PURPOSE:To efficiently adsorb a rare metal dissolved in seawater by taking-in a large quantity of seawater, by receiving an adsorbing chamber packed with an adsorbent at the packing ratio corresponding to the characteristic of the adsorbent in a structure not moving up and down along with a wave but performing relative motion. CONSTITUTION:An adsorbing chamber 1 and a buoyancy chamber 4 are provided under a wave surface 7 and columns 5 pierce through the wave surface 7 to adjust the whole submerged wt. and whole buoyancy of the apparatus to form structure making it possible to hold both chambers at draft. A scarce metal adsorbent 3 has a granular shape having specific gravity almost the same with that of seawater and water passing nets 2 provided to the upper and lower surfaces of the adsorbing chamber 1 under tension have a mesh size equal to or less than the average particle size of the rare metal adsorbent 3 in order to suppress the washing-away of said adsorbent. As mentioned above, by forming the large volume structure of the adsorbing chamber 1 and the buoyancy chamber 3 under seawater, the adsorbing chamber 1 is prevented from moving up and down along with seawater and a large quantity of seawater can be made to flow into the adsorbing chamber 1.

摘要： PURPOSE:To permit efficient power generation, maintaining the strength of a breakwater, by installing an air-turbine type wave-power generation set equipped with an air chamber and a resonance chamber in the breakwater and arranging the all apparatuses at a certain intervals in the breakwater. CONSTITUTION:In a generation set, the seawater in an air chamber 2 is moved up and down by waves 1, and the air in the air chamber 2 is allowed to flow through a nozzle 4, and an air turbine is revolved. Further, said generation sets are incorporated at certain intervals into a breakwater, and efficient power generation can be obtained by absorbing the wave energy in the amount more than that per air chamber width, owing to the mutual resonance. Since the whole system are incorporated into the breakwater 9 at an interval of L, with a cover 6 in the upper part of a resonance chamber 3, the strength of the breakwater is not deteriorated.

摘要： PURPOSE: To increase wave force generated power by providing a 4 or 2 blade valve system valve box on the upper portion of a air chamber opening the lower surface to waves to convert air flow produced in the reciprocating direction by waves to a single direction for rotating an air turbine.
CONSTITUTION: Two ducts 42, 43 are provided on the upper portion of a air chamber 41 provided in a marine structure. In the respective outlets of these ducts are mounted wells turbines 44, 45 on both ends of a shaft 46 of a generator 47 which generates power by rotation while holding the generator shaft 46 with bearing 48, 49. An air flow guide plate 50 is secured fixedly to the outer body of the generator 47 to guide outward air flow from the outlets of the ducts 42, 43. Right- ward force 55 in ascent of wave surface or leftward force 56 in descent of same acts on a symmetrical blade 1 of the wells turbine 44 respectively through the air flows 53, 54 produced within the duct 42 by the wave surface lifting movement 51 and lowering movement 52 in the air chamber 41.

摘要： PURPOSE:To hover water at depth containing feeding components for fish near the sea bottom by a vortex current generated with a flexible submarine sunk body having a fixed section in the stream on the sea bottom. CONSTITUTION:A flexible submarine sunk body comprising a float 11, a flexible sheet 10, a heavy matter 12 and an anchor set on the sea bottom helps generation of vortexes through repetition of fine deformation depending on the current of the sea water due to the flexibility of the sheet 10 itself. On the other hand, the current is reduced so substantially to develop an area of quick even flow on a float 11. Therefore, it is possible to hover water at depth rich in nutritions and feeding components for fish up close to the surface from near the sea bottom.
