Moreover, it is preferable that the horizontal wave collecting wall 2a is also formed in the upper and lower wave collecting portions 2b.

Underwater means a contrast to the above “near the water surface”, and in the present embodiment means below the wave collecting plate 2. In the case where power generation is performed using a wind whose wave traveling direction is not constant as in the first embodiment, the inertial plate 3 is preferably formed in a circular shape like the wave collecting plate 2.

The horizontal wave collecting wall 3a preferably extends in a direction facing the wave collecting plate 2 and is arranged in a radial pattern in plan view. The horizontal wave collecting wall 3a also serves as a stiffening wall.

The upper and lower wave collecting portions 3 b of the inertial plate 3 are formed in a shape in which the periphery of the inertial plate 3 is inclined or curved toward the lower side of the inertial plate 3. The inclination angle or curvature of the upper and lower wave collecting section 3b is preferably set equal to the inclination angle or curvature of the upper and lower wave collecting section 2b of the wave collecting plate. Moreover, it is preferable that the horizontal wave collecting wall 3a is also formed in the upper and lower wave collecting portions 3b.

The vertical translational motion or rotational motion of the wave collecting plate 2 serving as the driving source depends on the vertical change of the water surface caused by the wave entering between the wave collecting plate 2 and the inertial plate 3 and the elastic expansion / contraction change by the elastic expansion / contraction device 4. Arise.

  Here, the up-and-down translational movement of the wave collecting plate 2 is a vertical movement (heave) in which the position of the wave collecting plate 2 slides upward or downward evenly in any part before and after the vertical change of the water surface by the wave. Say.

  On the other hand, the rotational movement of the wave collecting plate 2 is a movement in which the position of the wave collecting plate 2 moves upward or downward in a certain part and not in other certain parts before and after the vertical change of the water surface by waves.

Specifically, the swinging motion of the current collecting plate 2 (mainly the pitching of the current collecting plate 2) that swings like a seesaw around the center of the current collecting plate 2 as a fixed point, This is the combined rotational movement (mainly the combined movement of pitching and rolling of the wave collecting plate 2) of the wave collecting plate 2 that moves the peripheral edge of the wave collecting plate 2 up and down in order along the periphery with the center as a fixed point.

  In addition, it is rare that the up-and-down translational movement or the rotational movement of the wave collecting plate 2 occurs independently, and usually the up-and-down translational movement and the rotational movement of the wave collecting plate 2 are mixed.

  The third wave power generator 5C is provided at the center of the wave collecting plate 2 as shown in FIG. The third wave power generator 5C is a device that preferably generates electric power mainly with respect to the rotational movement of the wave collecting plate 2. As shown in FIGS. 2, 4, and 5, the bowl-shaped body 7b, the magnet It has a unit 5Cd and a coil 5Cc.

  As shown in FIG. 2, the bowl-shaped body 7 b is fixed to the center of the wave collecting plate 2. As described above, the bowl-shaped body 7b constitutes a part of the flat spherical floating body 7 together with the support body 7a of the first wave power generator 5A.

In the first embodiment, as shown in FIGS. 2 and 6, a plurality of magnets 6f are circularly arranged on a bowl-shaped mounting portion 6e that rotates together with the horizontal impeller 6a, and the plurality of magnets 6f rotate. Thus, the wind power generator main body 6c is formed such that the plurality of coils 6g arranged in a circle on the inner surface of the support 7a of the first wave power generator 5A generate an induced electromotive force.

  Next, the operation of the wave power generation device 1 of the first embodiment will be described.

  In the conventional wave power generation device 1, energy loss occurs when the energy of the wave is taken in as mechanical energy of the wave power generation device 1. This is because the wave breaks before the wave energy is converted to mechanical energy.

  Therefore, in the wave power generation device 1 of the first embodiment, as shown in FIGS. 1 and 2, the wave collecting plate 2 and the inertia plate 3 are disposed substantially parallel to the water surface. Since the wave collecting plate 2 and the inertial plate 3 narrow the wave path, the wave that flows in causes a pressure change between the wave collecting plate 2 and the inertial plate 3 based on Bernoulli's principle, and between them Push out.

  Here, the inertial plate 3 submerged in water is hardly moved because it receives a great resistance from the seawater to the vertical movement. That is, the inertial plate 3 plays a role equivalent to a large inertial mass. On the other hand, since the wave collecting plate 2 is generally disposed on the water surface or at a position higher than the water surface, the wave collecting plate 2 performs a translational motion or a rotational motion by the water pressure generated by the waves.

  Further, in the first embodiment, as shown in FIGS. 1 and 2, an elastic expansion / contraction device 4 that expands / contracts the distance between the wave collecting plate 2 and the inertial plate 3 is provided. Therefore, the wave energy is efficiently and sufficiently converted not only to the kinetic energy of the wave collecting plate 2 but also to the elastic energy of the elastic telescopic device 4 as the mechanical energy of the wave power generation device 1.

  Therefore, the wave power generators 5A, 5B, and 5C are wave collecting plates that are generated in accordance with the vertical change of the water surface caused by the wave that has entered between the wave collecting plate 2 and the inertia plate 3 and the elastic expansion and contraction change by the elastic expansion and contraction device 4. It is possible to efficiently and sufficiently convert mechanical energy based on two vertical translational motions or rotational motions into electrical energy.

  Further, in the wave power generation device 1 of the first embodiment, as shown in FIGS. 1 and 2, a plurality of horizontal wave collecting walls 2 a and 3 a are provided on at least one of the wave collecting plate 2 and the inertial plate 3. Preferably it is formed. The horizontal wave collecting walls 2a and 3a function to collect waves in a plane (sea surface). Waves accumulated in the plane by the horizontal wave collecting walls 2a and 3a further increase the height of the wave that has entered between the wave collecting plate 2 and the inertial plate 3 by the accumulated amount. Vertical translation and rotation are further promoted.

  That is, since the horizontal wave collecting walls 2a and 3a can efficiently and sufficiently convert the vertical movement of the water surface by the wave into the vertical movement of the wave collecting plate 2, the conversion efficiency of the wave power generator 1 is improved.

  Further, in the wave power generation device 1 of the first embodiment, as shown in FIGS. 1 and 2, the upper and lower wave collecting portions 2 b and 3 b are formed on at least one of the wave collecting plate 2 and the inertial plate 3. ing. The upper and lower wave collecting portions 2b and 3b collect the waves up and down and smoothly introduce the waves between the wave collecting plate 2 and the inertial plate 3 without destroying them as much as possible.

  Further, the interval between the upper and lower wave collecting portions 2 b and 3 b is wider than that between the other wave collecting plates 2 and the inertia plate 3. Therefore, as compared with the case where the upper and lower wave collecting portions 2b and 3b are not provided, the pressure of the wave introduced between the other wave collecting plate 2 and the inertial plate 3 through the upper and lower wave collecting portions 2b and 3b. Is enhanced.

  That is, even if a high wave approaches the wave collecting plate 2 and the inertial plate 3, the high wave is suitably captured between the wave collecting plate 2 and the inertial plate 3 by the upper and lower wave collecting portions 2b and 3b, and the high wave Thus, the vertical movement of the water surface can be efficiently and sufficiently converted into the vertical movement of the wave collecting plate 2.

  Moreover, in the wave power generator 1 of 1st Embodiment, as shown in FIG. 2, the 1st wave power generator 5A is provided in the center of the wave collection board 2. As shown in FIG. The first wave power generator 5A does not employ a power generation method based on the gyro effect, but employs a direct conversion method from mechanical energy to electrical energy. In addition, the first wave power generator 5A uses the inertial force of the inertial mass 5Ae obtained from the vertical movement of the wave collecting plate 2 and the elastic expansion / contraction motion of the elastic expansion / contraction device 4 as a relative movement between the magnetic field of the magnet 5Ab and the coil 5Ac. Therefore, the transmission mechanism for converting from mechanical energy to electrical energy is simplified. As a result, it is possible to reduce the energy conversion loss in the intermediate mechanism for energy transmission and to eliminate the limitation of the power generation method due to the gyro effect and improve the power generation efficiency.

The second wave power generator 5B employs a direct power generation method with improved power generation efficiency, as described above. In addition, since the second wave power generator 5B is disposed at the periphery of the wave collecting plate 2, the greater the rotational movement of the wave collecting plate 2, the more efficient the mechanical energy of the wave collecting plate 2 is in electrical energy. Can convert well and well. That is, particularly when a rotational motion is generated in the wave collecting plate 2, the mechanical energy of the wave can be efficiently and sufficiently converted into electric energy.

  In the wave power generator 1 of the first embodiment, a third wave power generator 5C is provided in the center of the wave collecting plate 2 as shown in FIG. The third wave power generator 5C employs a direct power generation method with improved power generation efficiency as described above. In the third wave power generator 5C, the coil 5Cc generates a larger induced electromotive force as the magnet unit 5Cd travels faster. From this, the third wave power generator 5C has a large combined rotational motion of the current collecting plate 2 (mainly, a combined motion of pitching and rolling of the current collecting plate 2) among the rotational motions of the current collecting plate 2. Indeed, the mechanical energy of the wave collecting plate 2 can be efficiently and sufficiently converted into electrical energy.

However, it is arranged in a V-shape in plan view that narrows as it advances in the direction of undulation. In this case, the vertices of the V-shaped arrangement of the plurality of horizontal wave collecting walls 2a and 3a are arranged on an imaginary line L that is orthogonal to the wave traveling direction and passes through the center of the wave collecting plate 2 or the inertial plate 3.

The stiffening walls 2f and 3f extend in a direction opposite to the inertial plate 3 or the wave collecting plate 2 in at least one of the wave collecting plate 2 and the inertial plate 3, and are arranged in parallel with the wave traveling direction. Has been.

  Further, the wave power generator 1 of the second embodiment is replaced with the first wave power generator 5A as shown in FIGS. 7 and 8, or in combination with the first wave power generator 5A. The wave power generator 5 </ b> D is preferably provided on the imaginary line L in the wave collecting plate 2. The fourth wave power generator 5 </ b> D is a device that suitably generates power mainly with respect to the swinging motion (mainly pitching) of the wave collecting plate 2 in the direction of swell in the rotational movement of the wave collecting plate 2. The rotor 5Da, the coil 5Dc, and the magnet 5Db are included.

  As shown in FIGS. 8 and 9, the rotor 5Da is built in the cylindrical floating body 5Dd. In the wave collecting plate 2, the direction of undulation and the direction perpendicular to the vertical direction are the axial direction of the rotation shaft 5Dg. Accordingly, the rotor 5Da is rotated based on the inertial force extracted from the vertical movement of the wave collecting plate 2. The size and weight of the rotor 5Da are preferably set according to weather conditions such as wave height and wind strength in the area where the wave power generation device 1 is used.

  As shown in FIGS. 8 and 9, the coil 5Dc is fixed to the periphery of the rotor 5Da. It is preferable to use a plurality of coils 5Dc, and it is preferable to arrange them in a circular shape when viewed from the axial direction of the rotor 5Da.

  As shown in FIG. 8, the magnet 5Db is disposed on the inner peripheral surface of the cylindrical floating body 5Dd along the outer periphery of the rotor 5Da. Accordingly, the magnet 5Db generates an induced electromotive force in the coil 5Dc based on the vibration or revolution of the coil 5Dc generated by the rotation of the rotor 5Da. It is preferable to use a plurality of magnets 5Db, and it is preferable that the magnets 5Db are arranged in a circular shape when viewed from the axial direction of the rotor 5Da.

  Although not shown, the positional relationship between the coil 5Dc and the magnet 5Db may be changed on the condition that the principle of electromagnetic induction is established.

  Next, the operation of the wave power generation device 1 of the second embodiment will be described.

  In the wave power generation device 1 of the second embodiment, as shown in FIG. 7, a plurality of horizontal wave collecting walls arranged in a V shape in plan view on at least one of the wave collecting plate 2 and the inertial plate 3. 2a and 3a are formed. The plurality of horizontal wave collecting walls 2a and 3a arranged in a V shape in a plan view function to collect waves in a plane as in the first embodiment. Waves accumulated in the plane by the horizontal wave collecting walls 2a and 3a further increase the height of the wave that has entered between the wave collecting plate 2 and the inertial plate 3 by the accumulated amount. Vertical translational motion and rotational motion are promoted. Thereby, the vertical movement of the water surface by a wave can be efficiently and fully converted into the vertical movement of the wave collecting plate 2.

  Moreover, in the wave power generation device 1 of the second embodiment, as shown in FIG. 7, the vertices of the V-shaped arrangement of the plurality of horizontal wave collecting walls 2a and 3a are arranged on the virtual line L. Preferably it is. As a result, the most waves are accumulated on the imaginary line L of the wave collecting plate 2 and the inertial plate 3, so that the rocking motion (mainly pitching) of the wave collecting plate 2 in the swell traveling direction is most efficient and sufficient. Can be done. As a result, the vertical movement of the water surface due to waves can be efficiently and sufficiently converted into the vertical movement of the wave collecting plate 2.

  Further, in the wave power generator 1 of the second embodiment, as shown in FIG. 7, at least one of the wave collecting plate 2 and the inertia plate 3 is provided with stiffening walls 2 f and 3 f. preferable. Thus, it is possible to prevent the wave collecting plate 2 or the inertial plate 3 from being bent due to the vertical movement of the water surface due to the wave, and the conversion efficiency from the vertical movement of the water surface due to the wave to the vertical movement of the wave collecting plate 2 being deteriorated. it can.

  Moreover, in the wave power generator 1 of 2nd Embodiment, it is preferable to provide 4D wave power generator 5D on said virtual line L of the wave collection board 2. FIG. As a result, when the traveling direction of the wave is fixed in a predetermined direction, such as swell, it is easy to apply an inertial force to the rotor 5Da by the rotational movement of the wave collecting plate 2, particularly the swinging movement (mainly pitching). The mechanical energy of the wave can be efficiently and sufficiently converted into electrical energy.

  Next, the wave power generator 1 of 3rd Embodiment is demonstrated.

  The wave power generator 1 of the third embodiment is an apparatus that generates power by an indirect conversion method that converts the mechanical energy of a wave into kinetic energy of a fluid and converts the kinetic energy of the fluid into electrical energy, It can be applied to both waves and waves.

  As shown in FIG. 10, the wave power generator 1 according to the third embodiment includes a floating body 7, a wave collecting plate 2, an inertia plate 3, an elastic telescopic device 4, and a wave power generator.

  The difference between the second embodiment or the first embodiment and the third embodiment is that, as shown in FIG. 10, the first to fourth wave power generators 5A are used as the wave power generator. Instead of 5D, the fifth wave power generator 5E is adopted, and the configuration of the elastic telescopic device 4 is slightly different.

  As shown in FIG. 10 or FIG. 11, the fifth wave power generator 5E includes a fluid pump 5Ee, a suction / dispensing valve 5Ef, and fluid generators 5Eh1, 5Eh2.

  As shown in FIG. 12, the fluid pump 5Ee alternately discharges and sucks fluid from the suction port 5Eea. Here, as shown in FIG. 10, the upper ends of the plurality of suspension rods 4 a of the elastic telescopic device 4 are fixed to the periphery or center of the wave collecting plate 2 through holes provided in the periphery and center of the inertial plate 3. The lower end applies pressure change to the fluid pump 5Ee directly or indirectly via the link member 5Ea. That is, as shown in FIG. 12, the fluid pump 5Ee uses a reciprocating motion of the piston 5Eeb linked to the vertical movement of the wave collecting plate 2 as a fluid drive source.

  In the third embodiment, the same wave collecting plate 2 and inertia plate 3 as those in the second embodiment are employed, and therefore, as shown in FIGS. A total of 20 fluid pumps 5Ee arranged in 2 rows and 5 columns are preferably used. On the other hand, in other embodiments, when the same wave collecting plate 2 and inertia plate 3 as in the first embodiment are adopted, as shown in FIGS. A total of eight fluid pumps 5Ee arranged are preferably used. The same effect can be obtained with a number of pumps other than those described above.

  As shown in FIG. 11, the suction / discharge valve 5Ef is formed to separate the fluid sucked and discharged alternately from the suction port 5Eea of the fluid pump 5Ee into the suction fluid and the discharge fluid. For example, as shown in FIG. 11 and FIG. 16, the discharging / dividing valve 5Ef discharges or sucks fluid from the connecting port 5Efa connected to the discharging port 5Eea of the fluid pump 5Ee and the connecting port 5Efa inside the discharging / dividing valve 5Ef. And a suction fluid check valve 5Efe and a discharge fluid check valve 5Efd provided in the vicinity of the discharge port 5Efc or the suction port 5Efb inside the suction and dispensing valve 5Ef. .

  As shown in FIG. 11, the fluid generators 5Eh1 and 5Eh2 are devices that generate electricity using the pressure of the suction fluid or the discharge fluid obtained from the suction / discharge valve 5Ef as a drive source. When a plurality of suction / discharge valve 5Ef are used, the fluid generator 5Eh1 for the discharge fluid and the fluid generator 5Eh2 for the suction fluid are either the discharge fluid collecting chamber 5Eg1 or the suction as shown in FIGS. Each is connected to the suction / dispensing valve 5Ef via the fluid collecting chamber 5Eg2.

  As the fluid generators 5Eh1 and 5Eh2, a conventional fluid generator such as a turbine generator can be used. In the third embodiment, as an example of the fluid generator 5Eh1 for discharge fluid, a horizontal turbine-shaped self-supporting fluid generator shown in FIG. 18 is used.

  As an example, the fluid power generator 5Eh1 of the third embodiment includes a turbine body 5Eha, a magnetic rotor 5Ehb, and a coil 5Ehc, as shown in FIG.

  As shown in FIG. 18, the turbine body 5Eha has an annular part 5Ehd, a connection pipe 5Ehe, an annular part inflow slit 5Ehf, and an annular part outflow slit 5Ehg. The annular portion 5Ehd is a member for revolving the magnetic rotor 5Ehb inside thereof. The connection pipe 5Ehe is a member for connecting the collecting chamber 5Eg1 or the suction / dispensing valve 5Ef and the annular portion 5Ehd, and is generally provided on the tangent line of the annular portion 5Ehd.

  The annular portion inflow slit 5Ehf is a slit for allowing the fluid introduced into the connection pipe 5Ehe to flow into the annular portion 5Ehd. The annular portion outflow slit 5Ehg is a slit for flowing out the fluid introduced into the annular portion 5Ehd to the outside, and is formed at a position counterclockwise from the annular portion inflow slit 5Ehf in the annular portion 5Ehd. . Here, the separation distance from the annular part outflow slit 5Ehg to the annular part inflow slit 5Ehf is set equal to or shorter than the total length of the magnetic rotor 5Ehb. Further, in order to avoid the turbulent flow generated between the annular portion outflow slit 5Ehg and the annular portion inflow slit 5Ehf and improve the outflow efficiency, the annular portion outflow slit 5Ehg is larger than the annular portion inflow slit 5Ehf. Is formed.

  As shown in FIGS. 18 to 20, the magnetic rotor 5Ehb has a rotor body 5Ehh, a drive fin 5Ehk, and a magnet 5Ehj. The rotor body 5Ehh is formed in a shape in which a rectangular frame is curved in accordance with the annular portion 5Ehd. A plurality of drive fins 5Ehk are used on the outer peripheral surface of the rotor body 5Ehh, and the inclination angle is such that the rotor body 5Ehh is pushed in the clockwise direction against the fluid flowing clockwise in the annular portion 5Ehd. It is attached with. The magnet 5Ehj is formed to have a shorter overall length than the rotor body 5Ehh, and is attached to the rear end side of the rotor body 5Ehh with respect to the fluid flowing clockwise in the annular portion 5Ehd.

  The coil 5Ehc is wound around the entire annular portion 5Ehd of the turbine body 5Eha with the traveling direction of the magnetic rotor 5Ehb as the axial direction.

  Next, the principle of power generation of the fluid power generator 5Eh1 according to the third embodiment will be described with reference to FIG.

  As shown in FIG. 21A, the fluid introduced from the connection pipe 5Ehe of the turbine body 5Eha flows into the annular portion 5Ehd through the annular portion inflow slit 5Ehf. Since the inflowing fluid flows clockwise in the annular portion 5Ehd due to the influence of the attachment angle of the connection pipe 5Ehe, the magnetic rotor 5Ehb built in the annular portion 5Ehd has a pressure that rotates clockwise due to the fluid. receive. Further, the fluid ahead of the rotating magnetic rotor 5Ehb receives a pressure that flows clockwise as the magnetic rotor 5Ehb rotates. And a part of fluid which received the pressure from the magnetic rotor 5Ehb flows out through the annular part outflow slit 5Ehg.

  As shown in FIG. 21B, when the magnetic rotor 5Ehb rotates clockwise inside the annular part 5Ehd and the magnet 5Ehj covers the annular part outflow slit 5Ehg, the inside of the annular part 5Ehd Since the fluid cannot flow out to the outside, it works to weaken the fluid force of the fluid rotating clockwise. Thus, the magnet 5Ehj is prevented from being completely blocked by making the circumferential length of the magnet 5Ehj shorter than the circumferential length of the annular portion outlet slit 5Ehg. In addition, when the fluid introduced from the connection pipe 5Ehe rotates the magnetic rotor 5Ehb clockwise via the drive fins 5Ehk of the magnetic rotor 5Ehb, or when the magnetic rotor 5Ehb rotates, the inertial force is reduced. As a driving source, the magnetic rotor 5Ehb smoothly continues to rotate clockwise. Therefore, the annular portion outflow slit 5Ehg, which has been slightly blocked by the magnet 5Ehj of the magnetic rotor 5Ehb, increases its opening again and starts to gradually open, and the fluid inside the annular portion 5Ehd continues to flow clockwise.

  Then, as shown in FIG. 21C, even when the magnetic rotor 5Ehb rotates clockwise inside the annular part 5Ehd and the annular part inflow slit 5Ehf is blocked by the magnet 5Ehj, the annular part inflow The fluid flowing in from the slit 5Ehf rotates the magnetic rotor 5Ehb clockwise via the drive fins 5Ehk of the magnetic rotor 5Ehb, and a part of the fluid that has not flowed out from the annular portion outlet slit 5Ehg is magnetic rotor 5Ehb. Extrude the back end. Therefore, the magnetic rotor 5Ehb continues to rotate smoothly in the clockwise direction. In addition, the annular portion inflow slit 5Ehf, which has been slightly blocked by the magnet 5Ehj of the magnetic rotor 5Ehb, becomes larger again and begins to gradually open, and the fluid inside the annular portion 5Ehd continues to flow clockwise.

  Further, it is important that the magnet 5Ehj starts to open the annular portion outlet slit 5Ehg in a state where at least drainage from the annular portion outlet slit 5Ehg is secured. Therefore, as described above, the dimension of the magnetic rotor 5Ehb, the dimension of the magnet 5Ehj, and the dimension of the drive fin 5Ehk are such that the dimension of the arc of the magnet 5Ehj is shorter than the dimension of the arc of the annular portion outflow slit 5Ehg. It is preferable to determine after sufficiently comparing with various dimensions of the part inflow slit 5Ehf and the annular part outflow slit 5Ehg. Furthermore, “the area of the annular portion outflow slit 5Ehg” − “the area of the magnet 5Ehj” is preferably equal to or slightly larger than the “area of the annular portion inflow slit 5Ehf”.

  By repeating the above-described phenomenon shown in FIGS. 21A to 21C, the magnetic rotor 5Ehb continues to smoothly rotate inside the annular portion 5Ehd of the turbine body 5Eha. The coil 5Ehc of the fluid generator 5Eh1 generates a dielectric electromotive force based on the rotational motion of the magnetic rotor 5Ehb, so that the fluid generator 5Eh1 generates power.

  Next, the operation of the wave power generator 1 of the third embodiment will be described.

  In the wave power generation device 1 of the third embodiment, the elastic telescopic device 4 and the fifth wave power generator 5E of the third embodiment are used. The elastic expansion / contraction device 4 of the third embodiment converts integrated mechanical energy generated from the vertical translational motion and rotational motion of the wave collecting plate 2 into fluid kinetic energy. The fifth wave power generator 5E uses the smooth rotational motion of the magnetic rotor 5Ehb to efficiently and sufficiently convert the kinetic energy of the fluid into electrical energy. As a result, by using the wave power generation device 1 of the third embodiment, the power generation efficiency can be improved.

  That is, according to the wave power generation device of the present embodiment, the above-described action is produced, so that the mechanical energy obtained from the waves can be efficiently and sufficiently converted into electric energy.

  In addition, this invention is not limited to embodiment mentioned above etc., A various change is possible as needed.

  For example, since the first wave power generator 5A to the fifth wave power generator 5E are not mutually exclusive, the wave power generator according to the third embodiment includes the first wave power generator 5A and the fifth wave power generator 5E. A fourth wave power generator 5D can also be attached. On the other hand, in each embodiment, only one type of wave power generator can be used.
