Description

The present invention relates to a scalloped power generation apparatus in which a generator built in a rotor that drives a reciprocating water flow against a blade of an impeller generates environment-conserving power.

Conventional thermal power generation using fossil fuels remains an obstacle to environmental impact, and nuclear power generation leaves enormous costs and permanent management burdens for decontamination of radioactive materials and deep disposal of nuclear waste. In addition, solar power generation and wind power generation include problems that further technological innovation is required to solve obstacles, such as lack of sunshine due to bad weather and rotation due to poor wind speed.

For example, the one disclosed in Patent Document 1 proposes a wave power generation system that generates electric power by changing the vertical movement of wave energy into a rotational force. In addition, the one disclosed in Patent Document 2 proposes a marine power generation device that generates power by changing a drop of high waves and undulations into a rotational force.

Japanese Patent No. 5177908 Japanese Patent No. 4260546

Although the above document devised a wave power generation system that generates power by converting sea level fluctuations of wave energy into rotational force as background technology, the problem of stabilizing high-efficiency power generation in the natural environment remains. In addition, in ocean power generation devices that generate power by converting the head of swells and undulations into rotational force, problems remain in steering operation, and both include the problem of securing the right to use the ocean for facility installation. It was.

The present invention is intended to solve the problems arising from such a conventional configuration, and since the energy of the waves that strike the coast is enormous, as an effective use of the water flow that the spilling waves and the pulling waves have, the reciprocating water flow The purpose is to realize a rippling generator that creates an inexhaustible environment-conserving power by the generator built in the rotor by mooring the rotor that drives the impeller blades to the surface of the rippling sea. It is.

In addition, in the undulating power generation device, a plurality of rotors are arranged in rows and columns, and one of the generators built in the rotor has a reinforced structure that outputs a high-voltage current. In addition to responding to the vertical movement and unbalanced movement of the rotor within a predetermined range, the structure avoids the attack of high waves and tsunamis. Provision is made for sending air that has been pressurized to a level that prevents the intrusion of seawater.

In order to achieve the above object, the present invention forms a cylindrical container-shaped rotor that moves by applying a reciprocating water flow to the blades of an impeller, and a cutout portion in which a middle abdomen is cut out in a square plate shape. A square plate-shaped board moored to the sea surface when the ripening water flows through the lower part, and a support mechanism that locks the rotor in a predetermined range within the predetermined range so as to cope with an unbalanced movement. The board has an arc plate-shaped forward and rear submarine plate that is connected or integrated forwardly toward the seabed, a generator built in the rotor, and a support shaft that rotatably connects the rotor to the outside air from the inside of the rotor. There is provided a corrugated power generation apparatus including a large-diameter laying hole for passing a power cable penetrating toward and a predetermined pressure generator for sending air to a small-diameter pressure feed hole parallel to the laying hole.

Further, the second problem solving means is that the predetermined pressure generator includes a cylindrical pump pipe having a T-shape in which the front and rear terminals sandwiching the support shaft draw a circular arc and face downward, and the pump pipe and the pressure feed hole. A cylindrical pipe joint that can be bent at least in the axial direction of the rotor, and an arc central portion of the pump pipe and a middle portion of each of the front end and the rear end. Allowed on the outside air side, a check valve that blocks the flow, a return spring means that engages in the center of the arc of the pump pipe and can be expanded in the left-right direction, and is connected to both ends of the return spring means and to the inner surface of the pump pipe On the other hand, a check valve that allows flow on the relative side that does not change the posture in the stationary stationary system while maintaining a narrow gap and prevents flow on the outside air side is incorporated.

The operation of the first problem solving means is as follows. In other words, the rotor that moves by applying the reciprocating water flow to the blades of the impeller is locked to the sea surface at the time of undulation, so that the generator built in the rotor can produce inexhaustible power for environmental conservation. In addition, the entire front and rear submarine plates cause a subsidence action instantly after being attacked by a high wave or tsunami, so that the entire device can dive from the sea surface toward the seabed. In addition, since the predetermined pressure generator communicates with the pressure feed hole through which air passes, it is possible to feed the predetermined pressure increased to the extent that the seawater is prevented from entering the rotor.

The second problem solving means is that the predetermined pressure generator is opposed to a check valve that does not change the posture in the opposite stationary system when the pump pipes arranged in the surfing motion of the board perform a reverse pendulum motion. By applying the pressure, the predetermined pressure can be generated in the pump pipe.

As described above, the shoreline power generation device of the present invention can secure the coastal scouring mitigation and the super-economic base load power source because the generator built in the rotor can produce infinitely environmentally friendly power. To do. In addition, since the entire device can be submerged from the sea surface toward the seabed, fatal damage and destruction are avoided. In addition, since a predetermined pressure increased to prevent the intrusion of seawater into the rotor can be sent, stable operation of the built-in generator is ensured.

Moreover, since the predetermined pressure generator can generate the predetermined pressure in the pump pipe, it exerts labor saving and maintenance-free effect for other electric power, a control device, a compressor, and the like.

Within the scope of the gist of the present invention, the present invention includes those to which known techniques are added and those in which known techniques are excluded from the present invention. The scope of the present invention is not limited to the following specific examples.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a scalloped power generation device. As described in the claims, “a cylindrical container-shaped rotor 3 that moves by applying a reciprocating water flow to a blade of an impeller 3 a, and a middle abdomen is squared. A rectangular plate-like board 2 moored on the sea surface when forming a notch 2a that is notched in a plate shape and entraining the upstream water flow at the top and the double water flow at the bottom, and a predetermined range of the rotor 3 contained in the notch 2a A support mechanism 4 that locks in response to an up-and-down movement and an unbalanced movement, and arc-plate-shaped front and rear submersible plates 2b and 2c that are connected to or integrated with the board 2 by tilting forward toward the seabed. The generator 6 built in the rotor 3 and the support shaft 3h that rotatably connects the rotor 3 are provided with a large-diameter laying hole 3i through which the power cable 6d that penetrates from the inside of the rotor 3 toward the outside air is passed.

In the above-described rippling generator 1, the reciprocating water flow is applied to the blades of the impeller to lock the rotor 3 that is driven, and the generator 6 built in the rotor 3 generates environmentally-conserving power. It is something that is going to be created infinitely. In addition, the entire front and rear submarine plates 2b and 2c cause a subsidence action instantly after being attacked by a high wave or a tsunami, so that the entire apparatus 1 is submerged from the sea surface toward the seabed.

In FIGS. 1 and 2, reference numeral 3 a denotes an impeller, which is formed in a plate shape having a ginkgo leaf shape, and is formed from a reinforced plastic (FRP) or an aluminum bronze molded body, and a water flow can be applied to the wing. In consideration of the sea surface environment at the time of undulation, the impeller 3a is provided with a "brim" that travels backward from the outer ring so that it has an L shape when viewed from the side. The rotor 3 intersects with the tangential direction of the rotor 3 (for example, orthogonal to the driving direction), and is connected in a stepped manner at equal intervals in the front-rear and left-right directions. The impeller 3a has a height of about 70 mm and a width of about 70 mm.

In addition, the impeller 3a has a structure in which the impeller 3a is folded in the reverse direction (for example, counterclockwise rotation direction) as shown on the left side of FIG. By doing so, high-speed rotation according to wave speed is realized. Further, with regard to the shape of the blades of the impeller 3a, most of the wings are swollen in the rotational direction on the sea surface that receives fine waves. Or most of the sea surface which receives a large wave has a bulge in the reverse rotation direction. Alternatively, instead of the impeller 3a, the shape may be 6 or more stars (for example, about 6 to 32 stars).

In FIG. 3, reference numeral 3 denotes a rotor, which is formed in a cylindrical container shape, and is composed of an abduction plate 3b, a flanged disk-shaped one side surface plate 3c, and the other side surface plate 3d. Moreover, it shape | molds from the reinforced plastic (FRP) and aluminum bronze molded object which do not have the magnetism of the same material as the impeller 3a. Regarding the shape of this rotor 3, although the magnitude and strength of the spilling wave and the pulling wave are caused by the strength of regional characteristics and seasonal winds, considering the average value, in addition to making the cylindrical diameter around 300 mm to 500 mm, the floating body width One of the generators 6 incorporating three or more sets has a configuration width for increasing magnetic force.

Further, the rotor 3 is required to have toughness and a high level of sealing, and the outer rotation plate 3b to which the impeller 3a is connected is subjected to a pressure higher than expected, so that the internal structure is not damaged and the triple structure or the triple structure. It is structured and locked to the sea surface in a semi-floating state. Here, how to prevent seawater from entering from the joint between the outer rotation plate 3b and the one side and other side plates 3c, 3d will be explained. In the case of aluminum bronze, the all-contact method by melting, and in the case of FRP, at the joint It uses the adhesive strength of resin materials that contain carbon fibers and ceramic fibers.

In FIGS. 1 and 4 to 7, 3 h is a support shaft, which rotatably connects the rotor 3 and is formed in a long round bar shape. Because of its high rigidity and high strength, high-strength brass with good corrosion resistance and wear resistance is cast. And it supports to the one side and other side bearings 3e and 3f provided in the rotational center of the one side and other side surface plates 3c and 3d. The bearings 3e and 3f are rolling bearing type oil-impregnated shield bearings, which are provided with a rolling bearing (not shown) for smooth rotation and a shield bearing for maintaining airtightness.

In the above oil-impregnated shield bearing, the bearing material is impregnated with a lubricating material in a porous material such as sintered alloy or growth cast iron, the thermal expansion of the lubricating oil due to frictional heat generated during operation, and the rotor 3 with seawater The lubrication oil circulates on the friction surface by supplying air that has been pressurized to prevent intrusion, etc., and has a function of maintaining high airtightness without facilitating rotation and leakage of the impregnated lubricant oil. Yes.

In FIG. 1, 2 is a board, which is formed in a square plate shape (for example, a substantially mountain shape when viewed from the side), and is formed from a porous elastic rubber molded body. A reciprocating water stream (e.g., spilling waves and pulling waves) can be passed through the top and bottom. Moreover, the notch part 2a which notched the middle abdominal part made into the same height as the outer diameter of the abduction board 3b in the shape of a square plate is provided. The rotor 3 can be driven in the notch 2a, and front and rear submersible plates 2b and 2c that are inclined forward in the seabed direction are integrated with the front and rear ends of the board 2. And of course, it is moored to the sea surface at the beach where there is no reef on the bottom of the sea, not to be influenced by the tides.

The submarine plates 2b and 2c are formed in a circular arc plate shape, and are formed from a porous elastic rubber molded body made of the same material as the board 2. These submersible plates 2b and 2c have a depression angle of 30 ° to 40 ° inclined forward in the seabed direction. Explaining the action, when a high wave or tsunami is attacked from the offshore side, a sinking action can be caused from the forward submarine plate 2b. Moreover, when a strong return wave is received from the bank side by the backward inclined portion, it is possible to cause a sinking action from the rear submarine plate 2c.

Further, the diving plates 2b and 2c are a chain 2g (for example, striking between the front diving plate 2b and an anchor 2f connected to the seabed or a tip of a leading rod (not shown) extending from the coast toward a predetermined sea. A cast material of aluminum bronze), and a catenary suspension line 2h (for example, twisted strands of aluminum bronze) straddling between the rear diving board 2c and the breakwater or wave breaker block. The power cable 6d is suspended in the sea by a normal buoy 2i floating at a key point and lashing (co-hung) on the catenary suspension line 2h with a wire (not shown).

The above-mentioned porous elastic rubber (for example, spring constant is 0,49-4,7 kN / cm) is acid resistance, alkali resistance, water resistance, microbial resistance, oil resistance, organic solvent resistance, compression resistance. It is an excellent material, and does not deform itself, and has little plastic deformation even in repeated compression over a long period of time. Moreover, since it is necessary to endure the shearing force by a horizontal load, the shear elastic modulus is set to 0, 1 to 0, 7 N / mm2.

In addition, when the porosity is less than 5%, the porous elastic rubber has a small equivalent damping coefficient and cannot be repeatedly removed, and when the porosity exceeds 50%, the compression strength is insufficient. In addition, in the range of 5 to 50% in the porosity, the one adjusted to the porosity having a predetermined floatability and toughness is used so that the strain can be 5 to 15%.

The above-mentioned reinforced plastic (FRP) is made of an unsaturated polyester resin that can be cured at room temperature and normal pressure, and is formed by a suitable method from extrusion, compression, injection, and mold forming. This FRP has features such as easy processing, low cost, light weight, high strength, and resistance to corrosion. In addition, you may employ | adopt carbon fiber reinforced plastics (CFRP) with high added value, such as glass removal, metal substitution, and weight reduction.

The aluminum bronze is a dynamic Cu alloy containing 5% Al (containing a small amount of Fe, Mn, Ni). The component invented by Jun Asato is also called Arms bronze, and is highly extensible. As-cast, the crystal grains become coarse, so Fe, Mn, etc. are added. Good workability, high strength, good corrosion resistance and wear resistance. Processed materials are used for machine parts and marine parts, and cast materials are used for gears, bearings, bushes, and the like.

The high-strength brass is an alloy in which Mn 0,5 to 5%, Al 0,2 to 7,5%, Fe 0,1 to 4% is added to 6/4 brass, and the strength and hardness are extremely high. Excellent hot forgeability, good wear resistance and multicolor. Manufactured as a bar or casting, it is used for ship screw shafts, pump shafts, bridge structural materials, and the like.

In FIGS. 5 and 6, reference numeral 4 denotes a support mechanism, which is provided in a reinforcing frame 2d connecting both ends of the notch 2a in order to enable stable driving of the rotor 3, and supports the right reinforcing frame 2d. The mechanism 4 will be described. A crab sandwiching machine 4a that can be moved up and down within a predetermined range of the rotor 3 (for example, 1/2 of the outer diameter of the outer rotation plate 3b) and a rotor assembled to the crab sandwiching machine 4a. 3 and a fulcrum attracting machine 5 which is locked so as to be able to cope with the unbalanced movement.

The above-described crab sandwiching machine 4a will be described with respect to one end shown on the left side of FIG. 6. One end of the first right support bar 4b is fixed so as to be rotatable while the opposing outer plate 5b and inner plate 5c are sandwiched between them. One end of the first left support bar 4c is fixed so as to be rotatable while the above-mentioned sandwiching is held, and the other end of the first right support bar 4b is fixed to one end of the second right support bar 4d so as to be rotatable. A left-side split gear in which the other end of the first left support bar 4c is rotatably fixed to one end of the second left support bar 4e and a standard gear formed on the other end of the second right support bar 4d is divided. 4f and a right-side split gear 4g obtained by dividing a standard gear formed at the other end of the second left support rod 4e meshing with the left-side split gear 4f are fixed to the reinforcing frame 2d so as to be rotatable. .

Here, the shape of the left-side split gear 4f will be described. The meshing range (for example, the operating width θ of the gear 4f = approximately 30 °) is set in the vertical direction (for example, the inward wall surface of the second right support rod 4d). ) To approximately 180 ° to approximately 150 ° and overhangs to the inner surface side. The shape of the right-side split gear 4g is such that the meshing range (for example, the operating width θ of the gear 4g = approximately 30 °) is approximately 180 with respect to the vertical direction (for example, the inward wall surface) of the second left support rod 4e. It is formed at an angle of approximately 210 ° and extends to the inner surface side.

In order to improve the accuracy of the vertical movement generated in the rotor 3, the crab sandwiching machine 4a is provided with a not-shown split gear of the same shape as the left-side split gear 4f at one end of the first right support bar 4b. An unillustrated split gear having the same shape as the right-side split gear 4g may be formed at one end of the left support rod 4c, and the split gears not shown may be engaged with each other. Furthermore, when meshing with good transmission efficiency (small “backlash”) is required, the two-stage spur gears or the helical gears that are misaligned may be used.

In addition, the left split gear 4f is provided with a frame groove 4j in which the center of the top end of the reinforcing frame 2d (in the long axis direction of the lower shelf) is cut out, and the bank is inserted from the left side to the right side of the frame groove 4j. The support pin 4h on the side is inserted into and supported by the shaft center of the left-side split gear 4f, and a retaining ring 4i for preventing falling off is closed on the support pin 4h. Further, the right-side split gear 4g is supported by an offshore support pin 4h that is inserted from the left side to the right side of the frame groove 4j into the shaft center of the right-side split gear 4g. The other retaining ring 4i for preventing falling off is closed.

Accordingly, as shown on the right side of FIG. 6, the crab pinching machine 4a has a vertical movement width S of the rotor 3 = 150 mm ≧ height of the impeller 3a h = 70 mm × 2 slightly, and the impeller 3a is notched on the board 2 By securing the area that does not protrude from 2a, the rotor 3 can be driven stably. However, a shock absorber (for example, an elastic rubber or a plate type or a coil type not shown) that reduces the impact when an unexpected impact exceeding the vertical movement width S of the rotor 3 (for example, drifting material or driftwood waste material) is received. Are attached to each contact portion (for example, around the fixed band 5a).

The one end side of the fulcrum attracting machine 5 shown on the right side of FIG. 6 will be explained. A fixed band 5a is connected to the support shaft 3h, and an off-shore side with a code omitted that protrudes (opposite) from the periphery for tightening the fixed band 5a. An embankment-side “brim” is provided, and one end of an orthogonal clevis ring 5d and one end of an inward bending-type orthogonal clevis ring 5f are rotatably fixed to the offshore side “brim”, and an orthogonal clevis is disposed on the dike-side “brim”. One end of the ring 5e and one end of an inwardly bent orthogonal clevis ring 5g (not shown) are fixed rotatably.

Further, the fulcrum attracting machine 5 has the other end of the offshore side orthogonal clevis ring 5d fixed to the outer plate 5b to be rotatable, and the other end of the offshore side inward bending type orthogonal clevis ring 5f is rotatable to the inner plate 5c. While the other end of the levee-side orthogonal clevis ring 5e is rotatably fixed to the outer plate 5b, and the other end of the dyke-side inwardly bent orthogonal clevis ring 5g is rotatable to the inner plate 5c. It is fixed.

Therefore, the fulcrum attracting machine 5 is locked so as to be able to cope with unbalanced movement of the rotor 3, and as the floating body width of the rotor 3 increases, the degree of drawing decreases, but the floating body width of the rotor 3 is reduced to 2, In the case of 0 m, the allowable moving width is 50 mm ≧ the estimated moving width of the rotor 3 is approximately 30 mm, and the stable driving of the rotor 3 is enabled by securing the allowable fulcrum pulling width.

3 and 4, reference numeral 6 denotes a generator, which is built in the outer rotation type rotor 3, and a stator core 6 e is joined to the support shaft 3 h. A wound-type stator 6f in which a coil-wound coil 6c in which coil sides are twisted into a slot shape is arranged on the stator core 6e in a three-phase winding form, and an inner circumference of the rotor 3 that circulates outside the wound-type stator 6f Two or more and even number of permanent magnets 6b are fixed to the surface 3g at equal intervals for different poles.

The stator core 6e is formed by laminating several layers of silicon steel plates (for example, formed from a compact obtained by adding a small amount of silicon to iron). This silicon steel plate is ferromagnetic that allows magnetic flux to pass well, and has an electric resistance greater than that of iron for current. Therefore, current called eddy current generated in the stator core 6e can be suppressed.

The coil-shaped stator 6f uses a coil as a conductor through which eddy current flows, and is arranged in a three-phase coil shape so that the coil-wound coil 6c wound around the slot 6g of the stator core 6e can generate power in the same phase. A balanced three-phase circuit is provided in which three groups of windings that are wound up with different numbers of turns and can be connected in series are connected. Note that an epoxy resin material or the like is applied and fixed to the die coil 6c wound up in a three-phase winding shape.

The rotor 6a is fixed to the inner peripheral surface 3g of the rotor 3 with two or more even-numbered permanent magnets 6b fixed at equal intervals for different poles. It uses the adhesive strength of resin materials mixed with ceramic fibers. The permanent magnet 6b is used to generate a magnetic field (field magnetic flux). By receiving power from one of the dedicated generators 6 built in the rotor 3, a strong magnetic field magnetic flux is created. The desired high current generator 6 is used.

The permanent magnet 6b is one of the ferromagnetic materials, and is a substance that remains magnetized even when the surrounding magnetic field is zero. In addition to ferrite and very strong samarium cobalt, neodymium, iron, and boron are used. A typical example is a neodymium magnet which is a rare earth magnet (Nd ₂ Fe ₁₄ B) as a main component.

Here, the principle of general three-phase alternating current power generation will be described. The coil 6c is arranged on a stator core 6e that is separated by an angle of 120 °, and the permanent magnet 6b is provided on the inner peripheral surface 3g of the rotor 3 that circulates outside. When the rotor 6a that is equally spaced for each of the different poles rotates, an electromotive force (for example, single-phase alternating current) that alternately changes direction is generated in each of the die-wound coils 6c. Accordingly, since the angle at which the three die-wound coils 6c are arranged is shifted by 120 °, the electromotive forces generated from the respective die-wound coils 6c (for example, called three-phase alternating current) are about 120 ° from each other. A phase difference will occur.

As shown in FIG. 4, the above-described wound stator 6f has a three-phase wound die-wound coil 6c arranged on a stator core 6e, and a lead wire 6h of the die-wound coil 6c and a power cable 6d. The core wire 6i is connected. Then, since the generated eddy current flows through the die winding coil 6c (three-phase winding), the three-phase alternating current can be transmitted to the outside through the power cable 6d passed through the laying hole 3i.

Further, since the winding stator 6f generates heat from the die winding coil 6c due to the eddy current, a heat collecting fin 3j joined to the inner peripheral surface 3g of the rotor 3 is provided, and the heat collecting fin 3j and the rotor 3 are incorporated. The heat generated in the rotor 3 is radiated to the outside (seawater side) through a rivet (not shown) having excellent heat transfer properties.

The above-described power cable 6d is provided with a controller (not shown). The controller rectifies the output three-phase alternating current into direct current using a rectifier, and turns it into direct current. The output terminal has a predetermined voltage (for example, 100 (V) a voltage direct current or an alternating current of 50 to 60 Hz). In addition, since the output voltage always fluctuates due to the difference in the wave size and the interval at the time of undulation, a capacitor that repeats storage and discharge is mounted as a standard to achieve smoothing.

That is, the rotor 6 that moves by applying the reciprocating water flow to the blades of the impeller 3a is locked to the sea surface at the time of undulation, so that the generator 6 built in the rotor 3 can produce inexhaustible environmentally friendly power. In addition, since the front and rear submarine plates 2b and 2c cause subsidence instantaneously after being attacked by a high wave or tsunami, the entire device 1 can submerge from the sea surface toward the seabed.

In FIG. 7, reference numeral 7 denotes a predetermined pressure generator. As described in the claims, “a predetermined pressure generator 7 for feeding air into a small-diameter pressure feed hole 7 a parallel to the laying hole 3 i. Is a cylindrical pump pipe 7b having a T-shape in which the front and rear terminals sandwiching the support shaft 3h form a circular arc and face downward, and at least the axial direction of the rotor 3 connecting the pump pipe 7b and the pressure feed hole 7a. X is a cylindrical pipe joint 7i that can be bent freely, and the center of the arc of the pump pipe 7b is fixed to the middle of each of the front end and the rear end. Non-return valves 7c and 7d for blocking the flow, return spring means 7e which is engaged in the center of the arc of the pump pipe 7b and can be expanded in the left-right direction, and connected to both ends of the return spring means 7e and the inner surface of the pump pipe 7b 7h, with a narrow gap Allowing flow to the relative side of attitude does not change in the system, the outdoor air is check valve 7f, a built-in 7g "to block the flow.

The predetermined pressure generator 7 communicates with the pressure feed hole 7a through which air passes, so that the rotor 3 is fed with a predetermined pressure that is increased to prevent the intrusion of seawater. Further, since the pump pipe 7b aligned with the wave riding operation of the board 2 performs a reverse pendulum motion, the check valves 7f and 7g that do not change the posture in the opposite stationary system are opposed to each other, and thus the pump pipe 7b enters the pump pipe 7b. The predetermined pressure is generated.

In FIG. 7, 7a is a pressure feed hole provided on the support shaft 3h for the purpose of passing outside air through the rotor 3, and is opened with a certain distance from the laying hole 3i through which the power cable 6d is passed. doing. This pumping hole 7a has one end opening inside the rotor 3 that opens toward the empty space of the rotor 3, and the other end opening on the outside air projects upward from the periphery of the fixed band 5a connected to the support shaft 3h. An opening is made from the space between the confronting “collars” with the reference numerals omitted toward the sky. A predetermined pressure generator 7 communicates with the other end port.

The pump pipe 7b is formed in a cylindrical shape having a T-shape in which the front and rear terminals sandwiching the support shaft 3h draw a circular arc and face downward, and the pump pipe 7b has a rising pipe opening and a pressure feed hole 7a. A cylindrical pipe joint 7i that connects the end opening is provided. The pump pipe 7b uses a non-permeable member made of reinforced plastic (FRP) or stainless steel (a high alloy type of special purpose steel). Note that the arc radius R of the pump pipe 7b = the radius of the rising part of the pump pipe 7b + the pipe joint 7i + the support shaft 3h.

Further, since the pump pipe 7b is subjected to a reverse pendulum movement and a left / right swing movement aligned with the wave riding operation of the board 2, it is necessary to fix the pump pipe 7b, so that the two-stage pipe fixing bracket is provided on the outer surface of the outer plate 5b. The rising pipe portion is fixed by tightening 7j. In order to cope with further strong shaking and swinging, the arc inner surface of the pump pipe 7b and the outer plate 5b may be connected by a fixing plate (not shown).

In addition, the pump pipe 7b is provided with check valves 7c and 7d which are fixed and opposed to each other inside the center of the arc and the front terminal and the rear terminal, respectively, and engages in the arc center of the pump pipe 7b. A coil-type return spring means 7e that can expand and contract in the left-right direction is connected to both ends of the return spring means 7e so as to maintain a narrow gap with respect to the inner surface 7h of the pump pipe 7b so as not to change the posture in the stationary stationary system. Built-in check valves 7f and 7g.

The pipe joint 7i is formed in a cylindrical shape that can be bent at least in the axial direction X of the rotor 3, and is formed of a porous elastic rubber molded body. This pipe joint 7i has a structure in which an unillustrated coiled spring steel is bonded to the inside, has flexibility and durability corresponding to repeated bending repeatedly, and withstands water pressure of about 10 m in depth.

In FIG. 7, 7c and 7d are fixed check valves, which are formed in a cylindrical shape (for example, a vertically split body is integrated), and a spherical valve is built in the vertically split body. The check valves 7c and 7d are made of special-purpose steel (austenitic) stainless steel, and are fixed to the center of the arc of the pump pipe 7b and the middle of the front terminal and the rear terminal (for example, pressed from the outside). A check valve is bonded to the pump pipe 7b and is opposed (for example, the valve seat surfaces face each other).

Each of the check valves 7c and 7d has one opening for taking in outside air at one end face, and a large number of pores through which intake air is passed at the other end face, and a predetermined interval between the many openings and one opening. And a valve that closes only one opening is incorporated. Thereby, the flow of air can be allowed only on the relative side, and the flow of air can be prevented on the outside air side.

The return spring means 7e is bent in a coil shape, uses a single spring steel (for example, a carbon steel system of special purpose steel), and has a predetermined return force. The return spring means 7e engages in the center of the arc of the pump pipe 7b and is provided so that it can expand and contract in the left-right direction. Further, check valves 7f and 7g having a predetermined mass and not changing the posture in the opposite stationary system are connected to both ends of the return spring means 7e, respectively.

In FIG. 7, reference numerals 7f and 7g are check valves, which have a predetermined mass, and the outside air sucked into the pump pipe 7b when the pump pipe 7b aligned with the wave riding operation of the board 2 performs a reverse pendulum motion. On the other hand, it is possible to oppose the mass. The check valves 7f and 7g may have different external shapes from the fixed check valves 7c and 7d. In addition, the description of the unsigned product to be configured is omitted for other members and parts and structures having the same function.

The check valves 7f and 7g described above do not change the posture in the stationary system with respect to the outside air taken in by the check valves 7c and 7d. Since the air flow is blocked, the air pressure is increased to prevent the intrusion of seawater into the pump pipe 7b by optimizing the pressure until a predetermined mass is reached (for example, a compression action is generated in the pipe). A predetermined pressure can be generated.

The above stainless steel is Fe-Cr-Ni engagement gold containing 12-26% chromium (Cr), 6-22% Ni, and further containing Mo, Cu, Ti, Nb, and is a high temperature austenite. It is a steel grade whose structure is brought to room temperature. 18-8 steel and 18-8Mo steel are representative. It has excellent corrosion resistance in a redox environment and is non-magnetic.

The above spring steel includes medium-high carbon steel containing 0.5 to 10% of carbon, Si-Mn, Mn-Cr, Cr-V, Mn-Cr-B, Si-Cr, Cr-Mo. A total of nine types of alloy steels to which etc. are added are defined by JIS. The spring manufacturing process includes materials-hot / cool forming-quenching / tempering, materials-patenting treatment-cold processing / materials-quenching / tempering-cold forming, and the like. Fatigue strength is the most important factor in springs, so short peening is performed to create a compressive residual stress on the surface and suppress the occurrence of fatigue failure.

Here, the operation of the predetermined pressure generator 7 will be described in detail. The offshore side fixed check valve 7c and the check valve 7f that does not change the posture in the stationary system due to the reverse pendulum movement of the pump pipe 7b to the offshore side. The outside air is taken in from the fixed check valve 7c into the space where the pressure is reduced. Subsequently, due to the reverse pendulum movement of the pump pipe 7b toward the bank, the fixed check valve 7c and the check valve 7f that does not change the posture in the stationary system are close to each other, and the fixed check valve 7c is A predetermined pressure can be fed into the center of the arc of the pump pipe 7b while the check valve 7f, which does not change the posture in the stationary system, compresses the taken-in intake air. Therefore, the check valve 7f can repeat the compression until the mass is reached.

That is, the predetermined pressure generator 7 is able to send a predetermined pressure that is increased to an extent that prevents the intrusion of seawater into the rotor 3 by communicating with the pressure feed hole 7a through which air passes. Further, the check pipes 7f and 7g that do not change the posture in the opposite stationary system are opposed to each other by the counter-pendulum movement of the pump pipes 7b arranged in the wave riding operation of the board 2, so that the counter pipes are pressed in the pump pipe 7b. The predetermined pressure can be generated.

The operation of the above configuration will be described below. That is, the rotor 6 that moves by applying the reciprocating water flow to the blades of the impeller 3a is locked to the sea surface at the time of undulation, so that the generator 6 built in the rotor 3 can produce inexhaustible environmentally friendly power. In addition, the front and rear submarine plates 2b and 2c cause subsidence instantaneously upon receiving a high wave or tsunami attack, so that the entire device 1 can submerge from the sea surface toward the seabed.

In addition, the predetermined pressure generator 7 is capable of feeding a predetermined pressure that is increased to a level that prevents the intrusion of seawater into the rotor 3 by communicating with the pressure feed hole 7a through which air passes. Further, when the pump pipe 7b arranged in the wave riding operation of the board 2 performs a reverse pendulum motion, the non-return valves 7f and 7 that do not change the posture in the opposed stationary system are opposed to each other, and thereby the pump pipe 7b enters the pump pipe 7b. The predetermined pressure can be generated.
