DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wave power generation method and apparatus, and more particularly to a method for obtaining high-quality effective power irrespective of a traveling direction of a wave and damaging or floating the float due to the wave power. The present invention relates to a wave power generation method and an apparatus therefor.

2. Description of the Related Art In recent years, the energy problem has been emerging as an international problem in various fields. One is air pollution due to the use of fossil energy, and the other is depletion of fossil energy. Therefore, the development of alternative energies is urgently required in light of any problem, and it is needless to say that such alternative energies must be able to eliminate the above two problems. Nor.

[0003] Hydroelectric power generation has long been used as a method of obtaining electric power, but a large area must be submerged for hydroelectric power generation. Furthermore, power generation equipment using wind power has also been used, but this requires strong wind to obtain sufficient power and cannot supply sufficient power in normal times.

On the other hand, as an alternative energy to fossil energy that is currently being developed and used, nuclear energy is the main species, but again, the harmful effects of nuclear waste processing and radioactive spills are caused by the international community. It is a major problem in the country and is subject to controversy.In Japan, it is difficult to select a place to set up a nuclear power generation facility or a nuclear waste reprocessing facility due to local selfishness or the distrust of nuclear power safety. There are many difficulties.

[0005] Further, a technique using solar thermal energy as so-called non-polluting energy which eliminates such problems has been actively researched and developed, and a certain amount of effective electric power can be obtained outside the atmosphere. However, in the atmosphere, the amount of sunshine fluctuates extremely due to the climate, and sufficient amounts of sunlight are not obtained due to air pollution. It is a fact.

Further, a tidal power generation method using a tidal difference has been developed, but this method is not only limited to a place where the tidal difference is large, but also has a limitation in satisfying demand. In view of such circumstances, a wave power generation method using wave power has been developed. As an example, Korean Patent No. 35,913 (corresponding US Pat. No. 5,066,867) created by the present inventor has been proposed. There is. According to the method of this patent, the force that a floating ship floated on the sea repeatedly gets on and off according to the progress of waves is converted into rotational force by a chain and a sprocket, and the generator is driven using the rotational force. Since this wave power generation method has a wave height of 1 m or more even when the deep sea waves are considered to be calm, not only can it always obtain power, but also it can be installed in the ocean that occupies 78% of the ground surface. Since there is almost no restriction on the selection of the installation site, the present invention brings about an effect of expanding the ground surface rather than the conventional power generation method which has reduced the ground surface by being installed on the ground.

[0007]

However, in this method, the center of the bottom of the floating boat is fixed to the end of the fixed wire rope fixed to the upper end of the rotating support on the frame installed on the sea, and the bottom of the floating boat is fixed to the bottom. Connect a movable wire, one end of which is fixed to the center, to the end of the chain that rotates the generator, and fix the weight to the other end of the chain. Make the connected chain run upward,
When the floating ship descends, the chain moves downward due to the weight of the weight.When the chain runs upward, the one-way clutch rotates the generator shaft, and when the chain runs downward, it moves in one direction. Since the generator is intermittently driven by the operation of preventing the shaft of the generator from being rotated by the clutch, there is a limitation in obtaining a large amount of high quality electric power that can be substantially used.

In such an apparatus, it is ideal that the floating boat is lifted on the fixed wire rope side as the traveling direction of the wave proceeds from the fixed wire rope side to the floating boat side. However, not only is the upper end of the rotating prop deeply installed in the seawater, but also the center of the bottom of the floating boat is fixed to the end of the fixed wire fixed to the upper end of the rotating prop. When the boat advances strongly, the floating boat is raised at an angle of 45 ° or more, and a very strong force is applied to the floating boat, for example, the wave force acts on the bottom surface of the floating boat. Therefore, there is a concern that the floating boat may be detached from the fixed wire rope or the fixed wire rope may be cut, and that the strong force may be transmitted to the rotating column and the frame via the rotating column to damage the entire apparatus.

[0009] The end of the fixed wire rope and the movable wire rope is fixed to the center of the bottom of the floating boat,
Since the upper end of the rotating prop is located below the sea surface, the side facing the surf of the floating boat is easily lifted even when the surf progresses from the fixed wire rope side to the floating boat side, and if the side facing the surf is raised, This is because the wave force exerts a horizontal force stronger than the force trying to raise the floating boat, and therefore the force trying to push the floating boat horizontally is stronger than the force required to drive the generator.

When the wave travels from the wire rope to the floating ship, the above-described power generation operation is performed.
If the direction of the wave is changed and the boat heads to the wire rope from the side or the front of the floating boat, the floating boat cannot automatically respond to this, and the wire rope will bend and the generator will not be able to rotate. The efficiency was further reduced.

Further, there is a problem that the fixed wire rope supporting the floating ship and the movable wire rope to which the weight is fixed are easily entangled with each other, so that power cannot be generated.

On the other hand, such a power generation means is installed on a frame, and a frame for transforming and transmitting the generated power and an office of a resident who performs various tasks such as management, repair and maintenance of the power generation facility. Facilities, such as houses and lodgings, must be installed, and the entire frame is connected to wires connected to anchor blocks fixed to the sea floor, causing the power generation effect while drifting as the waves progress. If it is severe, there is a fear that an accident such as the entire frame being shaken severely and washed away, or the facilities installed on the frame being damaged, etc.

Further, since a generator or a device for giving a rotational force to the generator is installed at a location 10 m or more below the sea floor, there is a great difficulty in repairing and maintaining these generators.

Accordingly, an object of the present invention is to drive a pressure fluid generating means such as a liquid pump or an air pump installed corresponding to each floating boat by the power generated by the getting on / off operation of the floating boat, and to obtain the pressure fluid generating means by each pressure fluid generating means. The present invention provides a wave power generation method and a wave power generation method capable of maximizing the power generation efficiency by combining the pressure fluids to be used and moving the turbine of the generator with the combined pressure fluid to always obtain a constant power. That is.

It is another object of the present invention to maintain an optimum state in which a floating boat automatically changes its wave force to the operation of getting on and off a floating boat even if the traveling direction of the floating boat is changed. Thus, it is possible to efficiently convert the wave power to the power required for power generation, and to prevent damage or loss of the floating boat.

Still another object of the present invention is to make it possible to always generate electricity smoothly without entanglement of a wire rope or the like for supporting a floating boat.

Still another object of the present invention is to prevent damage to the turbine and the pipeline when the pressure of the pressure fluid generated by the pressure fluid generating means driven by the floating boat rises above a set value. That is.

Still another object of the present invention is to provide a method for generating a rotational force by converting a moving motion of a floating boat into a rotational force and a pressure fluid generating means which is operated by the rotational force generating means to generate a pressure fluid. It is to make maintenance and repair of these very easy by installing them on a floating ship floating on the surface.

Still another object of the present invention is to prevent the facility from being damaged when a wave having a wave height higher than the maximum wave height set in consideration of the yearly climatic conditions at the installation location is hit. It is.

[0020]

The transfer is performed via a primary connection transfer pipe and a secondary connection transfer pipe to which a number of primary connection transfer pipes are connected.

In the step of transferring the pressurized fluid, when the pressure of the pressurized water exceeds a set value, the governor spill valve is automatically opened to reduce the pressure, and when the pressure of the pressurized fluid falls below the set value, The governor spill valve is automatically closed to allow normal transfer.

In the transfer step, when the governor spill valve cannot respond and a sudden large pressure is applied, a surge means installed at a predetermined position operates to prevent damage to the turbine and the transfer pipe. I do.

Is positioned on the bottom surface of the floating boat 500 so that it is always immersed in seawater, and when an air pump is used as the pressure fluid generating means 700, it is positioned on the upper side so that seawater cannot enter.

The one-way transmission means 800 applies only the rotational force of the rotary drum 610 generated when the driving wire rope 620 wound on the rotary drum 610 is unwound while the floating boat 500 rises by the wave force, and generates a pressure fluid generating means. 700
22, 23, and 24, as shown in FIGS. 22, 23, and 24.
A transmission shaft 810 extending in the axial direction from the transmission shaft 8;
10, a driving sprocket 830 connected to the one-way clutch 820, a driven sprocket 840 fixed to the shaft of the pressure fluid generating means 700,
30 and 840, and a chain 850.

The one-way clutch 820 is connected to the rotating drum 61
0 transmits the rotational force to the driving sprocket 830 only when the driving wire rope 620 rotates in the unwinding direction.
When 0 rotates in the winding direction, the rotational force is prevented from being transmitted to the driving sprocket 830. In the illustrated example, a one-way clutch bearing is used as the one-way clutch 820. However, any structure that can transmit only the one-way rotational force of the rotating drum 610 to the pressure fluid generating means 700 side can be adopted.

The pressure fluid transfer means 900 is shown in FIG.
As shown in FIGS. 12 and 27 to 35, the support member 31 is connected to the discharge port of the pressure fluid generating means 700.
, A transfer hose 910 connected to the upper end of the support member 310, a hollow tube 312 for transferring a pressure fluid formed inside the support member 310, and a pressure tube connected to the hollow tube 312 of the support member 310. The frame 100 includes a part of the frame 100 used for transferring a fluid, and a main transfer pipe 950 installed vertically to the power generation sector S1 and connected between the pressure fluid transferring frame 100 and the turbine T. .

The pressure fluid transfer hose 910 is inserted and connected to the upper end of the support member 310 of the swirling means 300, and has a cap member 911 which is rotatable and can maintain the security at the upper end of the support member 310. By connecting the pressure fluid transfer hose 910 to the cap member 911 via a packing (not shown), the pressure fluid transfer hose 910 is twisted or entangled regardless of the direction in which the turning means 300 turns. There is no such thing. For this reason, the upper end of the support member 310 and the cap member 9
A mechanical seal (not shown) for preventing leakage of a normal rotating part is provided between the apparatus and the apparatus.

The pressure fluid transfer hose 910 is attached to the connecting trunk 420 of the getting on / off support means 400, the wire rope 410, the support member 310 of the turning means 300, and the like so as not to be loose.

The pressure fluid transfer frame 100 is configured such that its sphere diameter increases from the outside of the entire facility to the central main transfer pipe 950 so as to use the pressurized water efficiently. That is, as shown in FIG. 27, the grid-like frame structure is divided into four parts as a whole, and another frame 100 sends out pressurized water to the frame 100 located on the center side,
The center frame 100 is directly connected to the main transfer pipe 950 to receive pressurized water from both sides.
At its distal end, the frame 100 thus used for pressure fluid transfer, ie, FIG.
Frames 100 other than the frame 100 shown in FIG. 7 are filled with compressed air to obtain sufficient buoyancy required by the frame structure.

The main transfer pipe 950 is installed at an upper portion of an auxiliary frame 160 installed upward at a position corresponding to the power generation sector S1 of the frame 100. The main transfer pipe 9
The pulsation generated during the transfer of the pressure fluid is reduced between the pressure fluid transfer frame 50 and the pressure fluid transfer frame 100, and the buoyancy for supporting the load of various facilities installed in the power generation sector S1 is provided. A surge tank 960 is installed.

The surge tank 960 is shown in FIGS.
As shown in FIG. 9, a cylindrical portion 961 fixedly installed on the bottom surface of the frame 100 and surrounding the lower end portion of the main transfer pipe 950.
And upper and lower spherical plates 962 and 963 forming upper and lower end surfaces of the cylindrical portion 961, and a manhole 964 is provided at the center of the lower spherical plate 963. As shown in FIGS. 30 and 31, the cylindrical portion 961 of the surge tank 960 may be formed of a double pipe, and an air pocket 965 filled with compressed air may be formed between the pipes. desirable. Here, when a liquid pump is used as the pressure fluid generation means 700, the pressure fluid transfer frame 1
The pressure fluid transferred from 00, that is, the pressure water is set to maintain a constant water level, and an air chamber 966 filled with compressed air having a constant pressure is formed above the internal pressure water W.

When the height from the main transfer pipe 950 to the surface of the pressure water W inside the surge tank 960 is small, air is sucked when the pressure water W is sucked out through the lower end of the main transfer pipe 950. When the air in the air chamber 966 is sucked into the pressurized water as described above, a water hammer phenomenon occurs in the transfer pipe, which has a serious effect on the turbine T. Should be done.

The internal pressure water W of the surge tank 960 is
In the northern hemisphere, it receives a force that attempts to rotate counterclockwise when viewed in a plane, and in the southern hemisphere, it receives a force that attempts to rotate clockwise due to the turning force associated with the Earth's rotation. W forms a vortex, and when the vortex is formed as described above, the water level rises, but the water level falls at the center, so that the height from the water surface at the center to the lower end of the main transfer pipe 950 is reduced, and the air chamber is reduced. Air will be sucked in from 966.

Therefore, as shown in FIG. 30, the pressure fluid transfer frame 10 located inside the surge tank 960
The bent portion 101 is formed at the end of the surge tank 960, and the pressure water flowing into the surge tank 960 from the bent portion 101 does not go to the center of the surge tank 960, and cancels the eddy current phenomenon due to the turning force described above. The pressure water flowing into the surge tank 960 from the pressurized fluid transfer frame 100 cancels out while flowing in the opposite direction to the vortex generated by the rotation of the earth.

In view of this, since the direction of the eddy current is formed counterclockwise in the northern hemisphere, the pressure water flowing into the surge tank 960 is caused to flow clockwise, and in the southern hemisphere, the direction of the eddy current is clockwise. Since it is formed, the pressure water flowing from the surge tank 960 is made to flow counterclockwise.

As shown in FIG. 29, the upper end of the main transfer pipe 950 is closed, and the turbine T
A branch pipe 952 connected to the turbine T is provided with a governor spill valve 970 at the branch point, as shown in FIGS. Is always kept constant. As shown in FIGS. 32 to 35, the governor spill valve 970 is attached to a spill hole (Spill Hole) 971 formed at a branch point of the main transfer pipe 950, and is attached outside the spill hole (971). Spillway
y) 972 and an opening / closing plate 973 rotatably installed on the outer wall of the main transfer pipe 950 to open and close the spillway 972
And an adhesion means 980 for bringing the opening / closing plate 973 into close contact with the outer end of the spillway 972.

As shown in FIG. 33, the spillway 972 is formed in the shape of a reducer whose cross-sectional area becomes smaller toward the outside, and a packing 974 is provided at the outer end thereof.

As shown in FIG. 32, the opening / closing plate 973 is rotatably opened and closed by supporting the upper end thereof on a bracket 975 fixed to the peripheral wall of the main transfer pipe 950 with a support shaft 976.

The contact means 980 is shown in FIGS.
As shown in FIG. 11, any structure may be used as long as the opening / closing plate 973 can be kept in close contact with the outer end of the spillway 972 to maintain confidentiality.
Movable pulleys 981 provided on both lower ends of 73, fixed pulleys 982 provided correspondingly on both lower ends of the main transfer pipe 950, and a movable pulley 981 having a start end fixed to the movable pulleys 981. A tight wire rope 983 wound between the fixed pulleys 982, and a weight 98 fixed to the end of the rope 983 and applying a load to pull the rope 983.
4 is desirable.

Here, the adhesion force to the outer end of the spillway 972 is determined by the weight of the opening / closing plate 973, the force acting in the closing direction by the water pressure acting on the outside, and the weight 98.
The weight of the pulley 98 acts on the wire rope 983 and pulls the movable pulley 981 toward the fixed pulley 982 side. This force is set in consideration of safety. When a multiple pulley structure is employed, a desired adhesion can be obtained even when a lightweight weight is used.

Referring to the multiple pulley structure, as shown in FIG. 35, the starting end of the wire rope 983 is fixed to a first fixed pulley 982a installed on one side of the peripheral wall of the main transfer pipe 950. First movable pulley 981a installed on one side of the lower end of 973 → second fixed pulley 982b installed coaxially with first fixed pulley 982a → first movable pulley 981
a second movable pulley 981b installed coaxially with a → a third fixed pulley 982c installed on the other side of the peripheral wall of the main transfer pipe 950 →
Third movable pulley 981c installed on the other side of opening / closing plate 973
→ A fourth fixed pulley 982d installed coaxially with the third fixed pulley 982c → a fourth movable pulley 981d installed coaxially with the third movable pulley 981c → a fifth fixed pulley installed coaxially with the fourth fixed pulley 982d. The winding direction is changed in the vertical direction again via the direction change pulleys 985 and 986, and the weight 984 is fixed to the end thereof.

The weight 984 is composed of a weight body 984a having a constant weight and a fine adjustment auxiliary weight 984b detachable from the upper end of the weight body 984a. The weight of the entire weight 984 is reduced by the allowable pressure of the pressure fluid. It can be adjusted.

As the turbine T and the generator G, those usually used for power generation are used.

FIG. 36, FIG. 37, and FIG.
1 shows various facilities installed in the main transfer pipe 95
The turbine T and the generator G driven by the turbine T are installed in the branch pipes 952 of each of the zeros and the generators G driven by the turbines T. The controller 991, the substation and power transmission facility 992, the office and the resident's lodging 993 are provided. Etc. are arranged.
The turbine T and the generator G are mounted on an auxiliary frame 1 having a predetermined height in a power generation sector S1 of the frame 100.
60 is attached. Here, since the auxiliary frame 160 projects upward from the frame 100 and is installed at a position higher than the sea level, the discharge port 170 of the turbine T is disposed at a position higher than the sea level.

On the other hand, when a liquid pump is used as the pressure fluid generating means 700, a drain passage D for discharging pressurized water discharged from the discharge port 170 of the turbine T onto the sea surface is provided, and an air pump is used. In such a case, the compressed air that has operated the turbine T may be discharged into the atmosphere, so that the installation of a drainage channel and the like can be omitted. here,
As the turbine T, a hydraulic turbine used for general hydraulic power generation is used when a liquid pump is used as the pressure fluid generating means 700 as in the illustrated example, and is driven by compressed air when air is used. Used air turbine is used.

Here, since the spiral tube 953 receives a force which tends to proceed counterclockwise due to the turning force in the northern hemisphere, it forms its spiral direction counterclockwise, and in the southern hemisphere it will proceed clockwise due to the turning force. Therefore, it is desirable to form the spiral direction clockwise. Although the example of the drawing is an example in which a liquid pump is used as the pressure fluid generating means 700 and a hydraulic turbine T is used as the turbine T, a discharge passage for pressurized water is formed, but when an air pump and an air turbine are used, The compressed air that drives the air turbine is installed to be discharged into the atmosphere.

The operation of the thus constructed wave power generator of the present invention will be described. First, the construction process will be described. The frame 100 and various facilities installed on the frame are very large in area and weight, and when installed on the sea, when the whole is completely assembled and moved to the installation place. Requires a large barge ship, etc., it takes a long time to move it, or there are times when the weather at sea suddenly changes and it is necessary to evacuate to the shore abruptly during the work. As indicated by the two-dot chain line, it is desirable to divide the parts into a number of parts, move them to the installation place with all the equipment installed for each part, and then assemble the parts.

After being moved to the installation place, the respective parts are connected and assembled to each other, and the frame 100 is fixed to a predetermined position in seawater by the frame supporting means 200 comprising a large number of anchor blocks 210, anchor ropes 220 and branch ropes 221. Support in a state floating at the depth. Here, frame 1
00 is located at the frame 100 into which compressed air is injected.
Force and anchor rope 220 and branch rope 2
It is determined by the length and the tension of 21 and is installed in a state where there is a little play even when the wave hits strongly, but does not largely deviate from the original place.

At this time, if there is a difference between the tension applied to the anchor rope 220 and the branch rope 221, the external force is applied only to the ropes 220 and 221 having the highest tension. , 221
Is broken by an external force, the ropes 220 and 221 having the next higher tension are all sequentially broken in a manner of being broken, so that the tension applied to each anchor rope 220 and the branch rope 221 is adjusted to be constant. .

Anchor rope 220 and branch rope 221
The tension is adjusted by tension adjusting means 250, and as shown in FIGS. 7 to 10, the connecting links 2 fixed to the upper end of the branch rope 221 and the bottom of the frame 100, respectively.
The tension is adjusted by tightening the tightening wire rope 255 wound between the rollers 363 and 364 provided on the shafts 51 and 252. At this time, a tension gauge (not shown) is attached to the end of the tightening wire rope 255. By doing so, the tension of the anchor rope 220 and the branch rope 221 can be uniformly adjusted as a whole.

On the other hand, depending on the condition of the sea or the seabed, an anchor rod may be partially or entirely driven into the seabed and the anchor rope 220 may be connected thereto.

When the surge tank 960 is assembled, the air pocket 965 and the air chamber 96
6 has a very large buoyancy, so it is very difficult to submerge it in seawater, so it is disassembled into many parts (four parts in FIG. 29), transported to the installation place, assembled in seawater, and then air pocket 965 and air pocket 965. It is desirable to inject compressed air into the chamber 966.

The surge tank 960 sufficiently supports the weight applied intensively in its upper part, that is, the power generation sector S1, by the buoyancy of the air pocket 965 formed in the peripheral wall and the air chamber 966 formed in the inside. .

Next, the power generation process will be described. First, floating boat 5
Describing the getting on / off operation of 00, as shown in FIG. 12, the floating boat 500 is always in a state of floating on the sea surface.
When there is no wave intensity, it is located on the average sea level (MSL), and when there is a wave, it gets on and off between the peak and valley of the wave.

At this time, the column member 31 of the turning means 300
0 protrudes above the sea surface, and a wire rope 410 and a connecting trunk 420 constituting the getting on / off support means 400 are provided at the upper end thereof.
Are connected diagonally downward toward the sea surface, and the edge on the tip side of the floating boat 500 is installed at the tip end of the connection trunk 420 so as to be vertically rotatable by hinge pieces 422, 510 and hinge pins 511. So, even if a strong wave hits, while maintaining the state where the rear end side of the floating ship 500 sinks in seawater,
The passengers will get on and off by the height of the waves, that is, the difference between the peaks and valleys of the waves.

The floating boat 500 is formed such that its own center of weight is shifted from the center to the rear end side.
Due to the arrangement of the drum casing part 520, the rotating drum 610, the one-way transmission means 800 and the pressure fluid generation means 700 installed thereon, the center of the entire weight is set so as to be deviated from the center to the rear end side. Since the pull-out position of the driving wire rope 620 is deviated from the center to the rear end side, the front end side of the floating boat 500 connected to the connecting trunk 420 of the getting-on / off support means 400 (the front side when viewed from the traveling direction of the waves). ) Is always raised without sinking in seawater, and the rear end side (rear side when viewed from the direction of the wave) is always submerged in seawater, maintaining a state inclined downward to the rear end side of the floating boat 500 Therefore, the getting on / off operation of the floating boat 500 is performed very smoothly.

That is, when the center of weight of the floating boat 500 is located at the center and the pull-out position of the driving wire rope 620 is located at the center, the force acting downward on the floating boat 500 is less than the entire length of the floating boat 500 in the short axis direction. And the front and rear ends maintain the same height, so that the front end of the floating boat 500 (the front side when viewed from the direction of the wave travel) has a bad influence regardless of the getting on / off movement of the floating boat 500. Due to the horizontal wave pressure of the applied wave, not only the getting on / off motion of the floating boat 500 is not smoothly performed, but also a strong force acts on the floating boat 500 and the supporting means 300 and 400 supporting the floating boat by the horizontal wave pressure. Although there was a problem that the floating boat and its supporting means were damaged, in the present invention, as shown in FIG. 14, the center of weight of the floating boat 500 and the position where the driving wire rope 620 was pulled out were deviated from the center to the rear end side. In particular, since it is located at one-third of the distance from the rear end, the force acting downward on the floating boat 500 is stronger at the front end side and weaker toward the rear end side. Side is always exposed above sea level,
Since it is maintained in a state of being inclined downward to the rear end side, not only the getting on / off operation of the floating boat 500 is smoothly performed by the wave,
Further, as shown in FIG. 15, since the tip side of the floating boat 500 is sharpened, the horizontal wave pressure (P) acting on the tip side is increased.
Acts on the bottom surface of the floating boat 500 inclined downward toward the rear end, and its vertical component (Pv) acts to raise the floating boat 500, so that the getting on / off operation of the floating boat 500 is performed more smoothly and strongly. Since the rotating force generating means 600 is operated by using the force when the floating boat 500 rises, larger power can be obtained.

On the other hand, the traveling direction of the wave is
In the case of going from 0 to the floating boat 500, the floating boat 500 continues the getting on / off operation according to the wave as shown in FIGS. 12 and 13 by the above-described operation, but when the traveling direction of the wave is changed,
The floating vessel 500 is pushed in the traveling direction of the wave by the wave, and the wave force pushing the floating vessel 500 acts on the boarding / alighting support means 400 and the turning means 300 supporting the floating vessel 500, and this force causes the boarding / alighting means 400 to turn. The horizontal extension line connecting the center of rotation of the turning means 300 and the center of the floating boat 500 acts as a force to match the traveling direction of the wave.

Therefore, in the initial stage when the traveling direction of the wave is changed, the wire rope 410 of the getting-on / off support means 400 tends to bend slightly, but the entire support member 310 to which the wire rope 410 is fixed straight turns. The extension line of the boarding / alighting support means 400 coincides with the traveling direction of the wave, and returns to the state shown in FIGS.
The getting on / off operation of 0 becomes smooth.

After all, the floating boat 500 automatically responds to the traveling direction of the waves and always receives only the waves traveling from the front end side. Therefore, the floating boat 500 receives the waves from the rear end side or from the side. Even if the tip side is raised or raised, the wave force mainly causes the floating boat 500 to get on and off without applying strong wave force to the floating boat 500 and damaging the floating boat 500 and other getting on / off support means 400 and the turning means 300 and the like. Since it acts as a force, the wave force can be used more efficiently.

Since the floating boat 500 is connected to the tip of the connecting trunk 420 by hinge pieces 422, 510 and a hinge 511 so as to be vertically rotatable, the rotational force generating means 60 is provided.
At the position where 0 is set, that is, at the position deviated rearward from the center, the width of getting on and off increases, and the operation of the rotating force generating means 600 described later is performed more smoothly and largely.

[0098] The process of generating the rotational force by the above-mentioned getting on / off operation of the floating boat 500 will be described. In the process of raising the floating boat 500 to the position of the surf, the driving wire rope 620 fixed to the tip of the arm member 323 is pulled. Then, the driving wire rope 620 wound around the rotating drum 610 is unwound, and the rotating drum 610 rotates against the rotating elastic member in accordance with the unwound length of the driving wire rope 620.

When the rotating drum 610 rotates, the pressure fluid generating means 700 connected via the one-way transmission means 800 connected to one side plate in the disk portion 612 constituting the rotating drum 610 is operated. That is, the rotating drum 61
0 rotates in a direction in which the driving wire rope 620 can be unwound, and the transmission shaft 810 fixed to one side of the disc portion 612 is rotated.
Then, the driving sprocket 830 connected to the transmission shaft 810 via the one-way clutch 820 rotates, and this rotational force is transmitted via the chain 850 and the driven sprocket 840 to operate the pressure fluid generating means 700. Generates a pressurized fluid.

Here, when the pressure fluid generating means 700 is a liquid pump, its suction port (not shown) is submerged in seawater, so seawater is sucked, pressurized, and discharged (not shown). ) To the pressure fluid transfer hose 910, and when the pressure fluid generation means 700 is an air pump, sucks and pressurizes outside air through a suction port exposed to the atmosphere, and discharges it to the pressure fluid transfer hose 910 through a discharge port. Will do.

Further, since the winding length of the driving wire rope 620 wound around the rotating drum 610 is set in consideration of the expected wave height depending on the installation location, a wave higher than the expected wave height hits, and the driving wire rope 620 is driven. When the wire rope 620 is completely unwound from the rotating drum 610 and the driving wire rope 620 is pulled in a normal direction with respect to the rotating drum 610, the driving wire rope 620 is separated from the rotating drum 610 by the action of the safety connecting means 640. The wave force that is disengaged and lifts the floating boat 500 is not transmitted to the driving wire rope 620 but is transmitted only to the boarding / alighting support means.
Since 00 absorbs the wave pressure while getting on and off, the wire rope 620 for driving, the floating boat 500 and each supporting means are not damaged. That is, the driving wire rope 6
20 is connected to the protruding end of the safety pin 642 inserted into the groove 641 formed in the rotating drum 610 in the normal direction, so that the driving wire rope 62
In a state where 0 is completely unwound, the safety pin 642 is pulled out by the force acting on the driving wire rope 620 in the normal direction of the rotating drum 610, and the driving wire rope 62 is removed.
0 will be removed from the rotating drum 610.

The safety pin 642 is connected to a bracket 646 provided on one side of the groove 641 by a fastening screw 647.
The safety pin 642 during normal times.
Is not detached from the groove 641 arbitrarily, but the driving wire rope 620 as described above is used.
When the pulling force acts on the rotating drum 610 in the normal direction, the safety operation is smoothly performed without any hindrance when the safety pin 642 is pulled out.

On the other hand, when the floating ship 500 descends to the wave valley indicated by the dotted line in FIG. 12, the driving wire rope 620 hangs down, and the rotating drum 610 is rotated by the rotating elastic member 630 in the opposite direction while the driving wire is rotated. The rope 620 will be wound. The one-way clutch 820 for transmitting the rotational force of the rotary drum 610 to the pressure fluid generating means 700 is provided by a one-way clutch 820 that rotates only when the rotary drum 610 rotates in a direction in which the driving wire rope 620 can be released. 830, and conversely, when rotating in the direction in which the driving wire rope 620 is wound, the rotational force is not transmitted to the driving sprocket 830. Therefore, in the direction in which the driving wire rope 620 is wound. When rotating, only the rotating drum 610 rotates, the driving sprocket 830 does not rotate, and the pressure fluid generating means 700 connected to the driving sprocket 830 by the chain 850 and the driven sprocket 840 is not movable. Therefore, the pressure fluid generating means 700 always operates only in the direction in which the pumping action occurs.

The process of transferring the pressure fluid by the movement of the pressure fluid generating means 700 described above will be described. The pressure fluid discharged from each pressure fluid generating means 700 is supplied to the turbine T through the pressure fluid transferring means 900 and exchanges with the turbine. It will be movable. In the transfer process of the pressure fluid, the pressure fluid flows through the pressure fluid transfer hose 910 connected to the discharge port of each pressure fluid generation unit 700 and the hollow tube 312 of the column member 310 connected to the transfer hose 910. After being attached to the pressure fluid transfer frame 100, it is transferred to the main transfer pipe 950. At this time, a check valve CV1 is provided at the end of each pressure fluid transfer frame 100.
Since the CV2 and CV3 are installed, the main transfer pipe 95 is always kept without the backflow of the pressurized fluid in the transfer process for each process.
0 to eliminate the loss of pressure fluid.

The pressurized fluid that has passed through the pressurized fluid transfer frame 100 is transferred from its end to the main transfer pipe 950 through the surge tank 960 and supplied to the turbine T from the main transfer pipe 950 to operate the turbine T. The generator G is operated by the movement to generate electricity. The pressure fluid that has reached the end of the pressure fluid transfer frame 100 flows into the surge tank 960, where the surge fluid in the surge tank 960 reduces the pulsation of the pressure fluid transferred from each direction and is supplied to the turbine T. It serves to reduce fluctuations in pressure and flow rate of the pressure fluid.

In this process, when the pressure of the pressure fluid passing through the main transfer pipe 950 rises above a set value, the governor spill valve 970 installed at the upper end of the main transfer pipe 950
Is moved to lower the pressure, so that a constant pressure fluid is always supplied to the turbine T side. That is, as shown in FIGS. 29 and 32 to 35, a spill hole 971 is formed in the peripheral wall of the branch point of the main transfer pipe 950.
The spillway 972 is installed outside the spillway, and the open end of the spillway 972 is closed by an opening / closing plate 973, and the opening / closing plate 973 always closes the opening end of the spillway 972 by close contact means 980. Main transfer pipe 950
When the internal pressure becomes equal to or higher than the set value, the internal pressure overcomes the force of bringing the opening / closing plate 973 into close contact by the contacting means 980 and opens the opening / closing plate 973 to discharge the pressurized fluid into the seawater, while the main transfer When the pressure in the pipe 950 drops below a set value, the closing plate 973 closes the spillway 972 due to the contact force of the contact means 980, so that a constant pressure fluid is always supplied to the turbine T.

The operation of the contacting means 980 will be described in more detail. A fixed pulley 98 provided on the peripheral wall of the main transfer pipe 950 will be described.
2 is wound around a fixed pulley 982 and a movable pulley 981 provided on both sides of a lower end of the opening / closing plate 973, and a weight 984 is provided at an end thereof.
Is fixed, and the weight acting in the vertical direction of the weight 984 is turned in the horizontal direction via the turning pulleys 985 and 986, and the wire rope 983 wound between the movable pulley 981 and the fixed pulley 982 is tensioned. Act in the direction that causes
As a result, the movable pulley 981 is pulled toward the fixed pulley 982, so that the lower end of the opening / closing plate 973 on which the movable pulley 981 is provided is closely attached to the fixed pulley 982, that is, the opening of the spillway 972.

That is, the force acting in the direction in which the opening / closing plate 973 is closed, that is, the force for closing the opening / closing plate 973,
Is determined by the force acting in the closing direction due to its own weight, the water pressure acting on the entire surface of the opening and closing plate 973, and the contact force by the contact means 980. If the pressure in the main transfer pipe 950 is equal to or less than the set value, the main When the pressure in the transfer pipe 950 and the closing force cancel each other or the closing force increases, the opening / closing plate 973 maintains the closed state. When the pressure in the main transfer pipe 950 is equal to or higher than a set value, the pressure is equal to the closing force. To overcome the opening and closing plate 97
3, the internal pressure is reduced while the pressure fluid in the main transfer pipe 950 is discharged into the seawater, and when the pressure in the main transfer pipe 950 becomes lower than the set value again, the main transfer is performed while returning to the closed state. The pressure of the pressure fluid supplied to the turbine T via the pipe 950 is always kept constant.

In the contact means 980, the movable pulley 9
81 and one fixed pulley 982 may be installed, but in this case, since the weight of the weight 984 must be increased, the first to fourth movable pulleys 981a. The use of a multi-stage pulley structure including 981d and first to fifth fixed pulleys 982a to 982e has an advantage that the weight of the weight 984 can be reduced.

The pressure fluid supplied from the main transfer pipe 950 through the above-described pressure fluid transfer process flows into the turbine T through the spiral pipe 953 connected to the branch pipe 952. Here, the spiral tube 953 forms the spiral direction counterclockwise in the case of the northern hemisphere, and forms the spiral direction clockwise in the case of the southern hemisphere. The pressure fluid can be utilized more efficiently by eliminating the pressure fluid.

When the pressure fluid generating means 700 is a liquid pump, the pressurized water discharged after moving the turbine and the turbine is discharged onto the sea surface through the discharge port 170 of the turbine T. The pressurized water is drained smoothly through the drain D because it is installed on the auxiliary frame 160 which is higher than the upper surface and the outlet 170 is located higher than the sea level. On the other hand, when the pressure fluid generating means 700 is an air pump, unlike the case of a liquid pump, the compressed air that has operated the air turbine T is exhausted to the atmosphere.

FIG. 36, FIG. 37, and FIG. 38 show an example of the turbine T and the generator G used in the present invention. I don't care. Electricity generated by the generator is transformed in the power generation sector S1 and then transmitted to land via a submarine cable or a sea overhead line.

FIG. 39 shows another example of installation of the wave power device of the present invention. This is a central control base HQ having a substation and a power transmission facility, an office and an accommodation in the center, and a central control base HQ. Around the power generation sector S1
And a power generation base SQ having a pressure fluid generation sector S2. The power generated at each power generation base SQ is combined at the central control base HQ to transform the power, and transmitted to land via a submarine cable or a sea overhead line. It was done.

In the present embodiment, since the power generation base SQ does not have a permanent resident, it is not necessary to set up an office or a lodging place in the power generation sector S1 described above, but only for inspection and repair of each power generation base SQ. If a sudden situation occurs due to a sudden change in weather, a facility that can be temporarily evacuated may be provided, and normal management and control may be performed by the central control base HQ.

The present invention is not limited to the above-described embodiments, but can be variously modified within the spirit and scope of the present invention.
