[0048] The sea wave energy collection system of the present invention collects sea wave energy by arranging a high-pressure water output type sea wave vertical energy collection system a, a mechanical rotation output type sea wave vertical energy collection system b, a unidirectional ocean current sea wave horizontal energy collection system c, and an omnidirectional ocean current sea wave horizontal energy collection system d. Different types of sea wave energy collection systems are used to collect sea wave energy in different directions, and can sensitively respond to different types of sea wave surface changes, thereby realizing the collection of sea wave vertical and horizontal energy, and converting them into high-pressure water for transmission. The coverage range is changed, and the response is more comprehensive.

[0049] See also Figure 2-8 The high-pressure water output type sea wave vertical energy collection system a of this embodiment includes a high-pressure water pipe 2 and a high-pressure water output type sea wave vertical energy collector 3 which can collect the sea wave vertical energy and convert it into high-pressure water, wherein the water outlet end of the high-pressure water pipe 2 is connected to the high-pressure water pipe network 1, the water inlet end of the high-pressure water pipe 2 is connected to the water outlet end of the high-pressure water output type sea wave vertical energy collector 3, and a one-way valve 4 is provided at the end of the high-pressure water pipe 2 to prevent the high-pressure water from flowing back.

[0050] Preferably, at least two high-pressure water output type sea wave vertical energy collectors 3 are connected in parallel to the high-pressure water pipe 2, and the water outlet end of each high-pressure water output type sea wave vertical energy collector is connected to the high-pressure water pipe 2 through the water outlet pipe 5, and the one-way valve 4 on the top of the water pressure cylinder 14 can be installed on the water outlet pipe 5. Using multiple high-pressure water output type sea wave vertical energy collectors 3 to collect energy has a wider coverage and collects more energy.

[0051] In this embodiment, by setting up a high-pressure water pipe 2, the high-pressure water generated by each high-pressure water output type sea wave vertical energy collector 3 can be collected on the high-pressure water pipe 2, so that the high-pressure water generated by the collector can be networked and uniformly output for utilization, which is very convenient to use.

[0052] Preferably, the high-pressure water output type sea wave vertical energy collector 3 includes a power duckweed 13 and a vertically arranged water pressure cylinder 14 and a piston rod 15, wherein the power duckweed 13 is placed on the sea wave surface, is a flat structure, and is a plastic box shell, which can float up and down with the sea wave surface. Its flat box structure can greatly increase the contact area between the power duckweed 13 and the sea wave surface, and the reaction is more sensitive. One end of the piston rod 15 is connected to the power duckweed 13, and the other end slides Inserted in the water pressure cylinder body 14, specifically, the piston rod member 15 includes an integrated piston and a piston rod, the piston is inserted in the water pressure cylinder body 14, the piston rod is connected to the power duckweed 13, a one-way valve 4 is provided on the top of the water pressure cylinder body 14 to prevent the pressed water from flowing back, a suction pipe 7 is provided on the water pressure cylinder body 14 below the one-way valve 4, the suction pipe 7 extends to the bottom of the sea water to facilitate water suction, and a one-way valve 4 is provided on the suction pipe 7 to prevent water from flowing back out of the suction pipe 7 when pressing water.

[0053] The high-pressure water output type sea wave vertical energy collector of this embodiment is provided with components such as power duckweed 13, water pressure cylinder body 14, piston rod 15, etc., and adopts thin power duckweed 13 to contact the sea wave surface, so as to make a rapid full-load response to the change of the vertical height of the sea wave surface. When the sea wave surface rises, the piston rod 15 moves upward under the impetus of the buoyancy of the power duckweed 13. At this time, the one-way valve 4 of the water suction pipe 7 is closed, the one-way valve 4 at the top of the water pressure cylinder body 14 is opened, and the piston of the piston rod 15 presses the water in the water pressure cylinder body 14 out; when the sea wave surface drops, the piston rod 15 moves downward under the pull of the deadweight of the power duckweed 13. At this time, the one-way valve 4 of the water suction pipe 7 is opened, the one-way valve 4 at the top of the water pressure cylinder body 14 is closed, and the piston of the piston rod 15 sucks seawater into the water pressure cylinder body 14. Such a reciprocating cycle can collect the vertical energy of the sea waves and realize the function of converting the vertical energy of the sea waves into high-pressure water.

[0054] Preferably, a plurality of cross-arranged annular ribs 16 and radial ribs 17 are provided in the power duckweed 13 , which effectively improves the structural strength of the power duckweed 13 and thus prolongs its service life.

[0055] Preferably, duckweed steel caps 18 are provided on the upper and lower sides of the power duckweed 13 to clamp it. The duckweed steel caps 18 are integral steel components with better structural strength. The piston rod 15 passes through the duckweed steel caps 18 and the power duckweed 13 respectively, and the piston rod 15 and the duckweed steel caps 18 are connected by connecting bolts 19. The power duckweed 13 is clamped and fixed by two duckweed steel caps 18, which is convenient for disassembly and assembly. Compared with the method of directly connecting the piston rod 15 with the power duckweed 13 with screws, or directly connecting the duckweed steel caps 18 with the power duckweed 13 with screws, it can avoid opening holes in the power duckweed 13, thereby preventing seawater from entering the power duckweed 13, thereby affecting the sensitivity of the power duckweed 13.

[0056] Preferably, a non-circular anti-rotation rib 20 is provided on the side of the duckweed steel cap 18 close to the power duckweed 13, and correspondingly, anti-rotation slots 21 adapted to the anti-rotation rib 20 are provided on both the upper and lower sides of the power duckweed 13, and the anti-rotation rib 20 is clamped in the anti-rotation slot 21. The duckweed steel cap 18 and the power duckweed 13 are installed by the anti-rotation rib 20 and the anti-rotation slot 21, which can prevent the power duckweed 13 from rotating relative to the piston rod 15, reduce the torque of the connecting bolt 19, and thus improve the connection reliability between the power duckweed 13 and the duckweed steel cap 18, and can realize the rapid positioning and installation of the duckweed steel cap 18, and the disassembly and assembly are more convenient.

[0057] Preferably, the connection between the piston rod 15 and the power duckweed 13 and the duckweed steel cap 18 is a square structure, which can further prevent the power duckweed 13 from rotating relative to the piston rod 15, and realize quick alignment of the bolt holes of the piston rod 15, making disassembly and assembly more convenient.

[0058] Preferably, a guide mechanism is further provided below the power duckweed 13, the guide mechanism comprising an extension rod 22 and a guide seat 23, wherein the guide seat 23 can be fixed on the seabed of the seabed, and the extension rod 22 slides through the guide seat 23 and is connected to the piston rod 15 through an embedded connecting screw 24. Through the setting of the guide mechanism, a guiding function is played during the up and down movement of the power duckweed 13, ensuring that the power duckweed 13 can only reciprocate in the vertical direction, reducing the bending moment of the piston rod 15, and thus extending the service life of the piston rod 15.

[0059] The energy collector in this embodiment further includes a fixed support 25 , which can be fixed on the seabed of the seabed. The water pressure cylinder body 14 is fixed on the fixed support 25 to achieve fixed installation of the water pressure cylinder body 14 .

[0060] See also Figure 5-10 The mechanical rotation output type sea wave vertical energy collection system b of this embodiment includes a water pump structure and a mechanical rotation output type sea wave vertical energy collector 6 that can collect sea wave vertical energy and convert it into mechanical rotation energy, wherein the mechanical rotation output type sea wave vertical energy collector 6 is linked with the water pump structure, and the water pump structure is connected with a water suction pipe 7 and a high-pressure water delivery pipe 2, wherein the water suction pipe 7 extends to the sea water. The outlet end of the high-pressure water delivery pipe 2 is connected to the high-pressure water pipe network 1, and a one-way valve 4 is provided at the end of the high-pressure water delivery pipe 2 to prevent the high-pressure water from flowing back. Specifically, the water pump structure includes a tympanic membrane box pump 32 and a crankcase 33, wherein the transmission shaft 28 of the mechanical rotation output type sea wave vertical energy collector 6 is linked with the input end of the crankcase 33, the output end of the crankcase 33 is linked with the tympanic membrane box pump 32, and the water suction pipe 7 and the high-pressure water delivery pipe 2 are both connected to the tympanic membrane box pump 32.

[0061] Preferably, at least two mechanical rotation output type sea wave vertical energy collectors 6 are connected in parallel to the transmission shaft 28, so as to cover a wider range and collect more energy.

[0062] The mechanical rotation output type sea wave vertical energy collection system of the present invention collects the mechanical rotation energy generated by each collector onto the unidirectional rotating transmission shaft 28 by setting up a water pump structure. The unidirectional rotating transmission shaft 28 drives the tympanic box pump 32 to operate through the crankcase 33, thereby pressurizing the seawater into high-pressure water and collecting the high-pressure water into the high-pressure water pipe 2 for unified output and utilization.

[0063] Preferably, the mechanical rotation output type sea wave vertical energy collector 6 includes a power duckweed 13 and a vertically arranged push-pull rod 26. The power duckweed 13 is placed on the sea wave surface, has a flat structure, and is a plastic box shell, which can float up and down with the sea wave surface. Its flat box structure can greatly increase the contact area between the power duckweed 13 and the sea wave surface, and the response is more sensitive. Positioning pulleys 27 are provided above and below the push-pull rod 26, and a transmission shaft 28 is provided on one side of the push-pull rod 26. Both ends of the transmission shaft 28 are connected with bearing seats to facilitate the installation of the transmission shaft 28, and the bearing seats can be installed on the seabed of the seabed. In this embodiment, three positioning pulleys 27 are provided, and a rectangle is formed between the axis connecting the three positioning pulleys 27 and the transmission shaft 28. The middle part of the push-pull rod 26 is connected to the power duckweed 13. The floating power duckweed 13 can push the push-pull rod 26 to move up and down. Both ends of the push-pull rod 26 are connected with steel cables 29. The transmission shaft 28 is connected with a sprocket 30 through a one-way wheel. In this embodiment, the one-way wheel can be a one-way bearing or a ratchet, which can realize the unidirectional rotation of the transmission shaft 28. A chain 31 is sleeved on the sprocket 30, and two steel cables 29 pass through the positioning pulleys 27 and are connected to the two ends of the chain 31.

[0064] The mechanical rotation output type sea wave vertical energy collector of this embodiment, by setting the power duckweed 13 and the push-pull rod 26, adopts the thin power duckweed 13 to contact the sea wave surface, can make a fast full-load response to the change of the vertical height of the sea wave surface, and the response is more sensitive. When the sea wave surface rises, under the pull of the buoyancy of the power duckweed 13, the push-pull rod 26 moves upward and drives the lower chain 31 to move through the steel cable 29, thereby driving the sprocket 30 to rotate clockwise, and the sprocket 30 further drives the transmission shaft 28 clockwise through the one-way wheel. The needle rotates; when the wave surface drops, under the pull of the buoyancy and self-weight of the power duckweed 13, the push-pull rod 26 moves downward and drives the upper chain 31 to move through the steel cable 29, thereby driving the sprocket 30 to rotate counterclockwise, but will not drive the transmission shaft 28 to rotate counterclockwise. Such a reciprocating cycle realizes the unidirectional transmission function of the transmission shaft 28 to avoid the unfavorable situation that the rotation directions conflict with each other when a transmission shaft is connected in parallel with multiple collectors. At the same time, the vertical energy of the sea waves can be collected, realizing the function of converting the vertical energy of the sea waves into mechanical rotational energy.

[0065] The energy collector in this embodiment also includes a guide seat 23, which can be fixed on the seabed of the seabed. The push-pull rod 26 is slidably inserted in the guide seat 23 to guide the push-pull rod 26 to slide up and down, ensuring that the push-pull rod 26 can drive the steel cable 29 to move, thereby improving the reaction sensitivity.

[0066] See also Figure 11-17The unidirectional ocean current and wave horizontal energy collection system c in this embodiment includes a water pump structure and a unidirectional ocean current and wave horizontal energy collector 8 that can collect the unidirectional ocean wave horizontal energy and convert it into mechanical rotational energy. Preferably, the unidirectional ocean current and wave horizontal energy collector 8 is linked to the water pump structure; the water pump structure is connected with a water suction pipe 7 and a high-pressure water pipe 2, the water outlet end of the high-pressure water pipe 2 is connected to the high-pressure water pipe network 1, and a one-way valve 4 is provided at the end of the high-pressure water pipe 2.

[0067] In this embodiment, the transmission shaft 28 is connected to a plurality of unidirectional ocean current driving wheels 34 arranged side by side, so as to cover a wide range.

[0068] In this embodiment, the water pump structure includes a tympanic pump 32 and a crankcase 33. The transmission shaft 28 of the unidirectional ocean current wave horizontal energy collector 8 is linked to the input end of the crankcase 33, and the output end of the crankcase 33 is linked to the tympanic pump 32. The water suction pipe 7 and the high-pressure water delivery pipe 2 are both connected to the tympanic pump 32. When the ocean current passes through the unidirectional ocean current driving wheel 34, the unidirectional ocean current driving wheel 34 drives the transmission shaft 28 to rotate, and the transmission shaft 28 drives the crankshaft in the crankcase 33 to rotate, and the crankshaft drives the transmission rod of the tympanic pump 32 to move back and forth in a straight line, so as to drive the tympanic pump 32, so that the water suction pipe 7 of the tympanic pump 32 sucks water from the ocean and enters the high-pressure water delivery pipe 2 after pressurization.

[0069] The unidirectional ocean current wave horizontal energy collector 8 in this embodiment includes a unidirectional ocean current drive wheel 34 connected to a transmission shaft 28, the transmission shaft 28 is arranged horizontally, and in this embodiment, the transmission shaft 28 is arranged horizontally. The unidirectional ocean current drive wheel 34 includes a wheel frame 37, and at least two power rotor blades 35 are distributed circumferentially around the transmission shaft 28 on the wheel frame 37. There are two wheel frames 37 and they are arranged in parallel, and the power rotor blades 35 are located between the two wheel frames 37. In this embodiment, each unidirectional ocean current drive wheel 34 has 6 power rotor blades 35.

[0070] The power rotor 35 is rotatably connected to the wheel frame 37 via a rotor support rod 36, wherein the power rotor 35 includes a weather-resistant plastic shell 48, in which a plurality of ribs 49 arranged side by side are provided, and the ribs 49 are fixedly connected to the weather-resistant plastic shell 48. The power rotor 35 also includes a metal bushing 50 passing through each rib 49 and the weather-resistant plastic shell 48, and the rotor support rod 36 passes through the metal bushing 50 and the two are rotatably connected.

[0071] A first vane limiting structure 42 is provided between the wheel frame 37 and the power vane 35 to limit the rotation angle of the power vane 35 when the power vane 35 rotates to the point where the front end of the power vane 35 faces outward and the rear end is adjacent to the transmission shaft 28. In this embodiment, the first vane limiting structure 42 is mounted on the wheel frame 37, specifically a vane stop lever, corresponding to the rear vane surface 52 of the power vane 35.

[0072] The power rotor 35 is wing-shaped, and includes a first rotor surface 46 and a second rotor surface 47 facing opposite directions, and the surface area of ​​the second rotor surface 47 is larger than the surface area of ​​the first rotor surface 46. The second rotor surface 47 includes a front rotor surface 51 and a rear rotor surface 52, and the connection between the front rotor surface 51 and the first rotor surface 46 constitutes the front end of the power rotor 35, and the connection between the rear rotor surface 52 and the first rotor surface 46 constitutes the rear end of the power rotor 35. When the power rotor 35 floats under the action of the sea current, the second rotor surface 47 faces the direction of the transmission shaft 28, and the front end and the rear end of the power rotor 35 are arranged along the sea current direction. Since the surface area of ​​the second rotor blade surface 47 is greater than that of the first rotor blade surface 46, it is wing-shaped. When the ocean current passes through the floating power rotor blade 35, the first rotor blade surface 46 and the second rotor blade surface 47 of the floating power rotor blade 35 have different pressures due to different flow rates, resulting in a pressure difference. The floating power rotor blade 35 is subjected to a thrust toward the other side of the transmission shaft 28, which helps to accelerate the rotation of the power rotor blade 35 and improve the energy conversion efficiency.

[0073] A second vane limiting structure 41 is provided between the wheel frame 37 and the power vane 35 to limit the rotation angle of the power vane 35 when the power vane 35 rotates to the rear end of the power vane 35 facing outward. In this embodiment, the second vane limiting structure 41 is a vane limiting pad, which is provided on the wheel frame 37 and corresponds to the front vane surface 51 of the power vane 35.

[0074] The unidirectional ocean current wave horizontal energy collector further includes a bracket 38, and the transmission shaft 28 of the unidirectional ocean current driving wheel 34 is rotatably connected to the bracket 38. The bracket 38 includes a duct 43, and the unidirectional ocean current driving wheel 34 is located in the duct 43. Specifically, the transmission shaft 28 is fixedly connected to the middle of the unidirectional ocean current driving wheel 34, and a bearing 40 is installed on the side wall of the duct 43. The inner ring of the bearing 40 is sleeved with a transmission shaft kit 39, and the transmission shaft 28 passes through the transmission shaft kit 39 and the two are fixedly connected by screws.

[0075] The bracket 38 is provided with a rectifying plate structure located in front of the one-way current driving wheel 34 along the current direction. The rectifying plate structure includes a first rectifying plate 44 and a second rectifying plate 45. The first rectifying plate 44 is arranged on the left and right sides of the entrance of the duct 43, and the second rectifying plate 45 is arranged on the upper and lower sides of the entrance of the duct 43. The second rectifying plate 45 located on the upper side of the entrance of the duct 43 corresponds to the trough of the sea wave during the ebb tide period.

[0076] In this embodiment, there are two one-way current driving wheels 34 and they are arranged along the direction of the current. The two one-way current driving wheels 34 are arranged along a plane mirror image perpendicular to the direction of the current. Wherein, the direction of the current is from left to right, and when the current passes through the one-way current driving wheel 34 on the left side, the power rotor 35 rotating to the top of the transmission shaft 28 floats up, and the rear end of the power rotor 35 rotating to the bottom of the transmission shaft 28 basically faces the transmission shaft 28, and at this time, the one-way current driving wheel 34 rotates counterclockwise. The current speed of the upper part of the counterclockwise rotating one-way current driving wheel 34 is faster, and it passes through the one-way current driving wheel 34 on the right side backwards. Then, in the one-way current driving wheel 34 on the right side, the rear end of the power rotor 35 rotating to the top of the transmission shaft 28 faces the transmission shaft 28, and the power rotor 35 rotating to the bottom of the transmission shaft 28 floats up. By setting two double current driving wheels rotating in opposite directions, the full cross-section collection of the current energy of the duct 43 is achieved.

[0077] See also Figure 18-19 The omnidirectional ocean current and wave horizontal energy collection system d of this embodiment includes a water pump structure and an omnidirectional ocean current and wave horizontal energy collector 9 which can collect the omnidirectional ocean wave horizontal energy and convert it into mechanical rotational energy. The omnidirectional ocean current and wave horizontal energy collector 9 is linked to the water pump structure; the water pump structure is connected with a water suction pipe 7 and a high-pressure water pipe 2, the water outlet end of the high-pressure water pipe 2 is connected with the high-pressure water pipe network 1, and a one-way valve 4 is provided at the end of the high-pressure water pipe 2.

[0078] The omnidirectional ocean current wave horizontal energy collector 9 of this embodiment includes an omnidirectional ocean current driving wheel 53 connected to a transmission shaft 28, and the transmission shaft 28 is arranged vertically. The omnidirectional ocean current driving wheel 53 includes a wheel frame 37, and at least two power rotor blades 35 are distributed circumferentially around the transmission shaft 28 on the wheel frame 37. There are two wheel frames 37 and they are arranged in parallel. The power rotor blades 35 are located between the two wheel frames 37. In this embodiment, each omnidirectional ocean current driving wheel 53 has six power rotor blades 35.

[0079] When the horizontal sea current hits the omnidirectional sea current drive wheel 53 in any direction, part of the power blades 35 will face the sea current after being supported by the blade lever, thereby forming a huge forward rotation thrust; while the other part of the power blades 35 are not supported by the blade lever, and will be blown up by the sea current, minimizing the flow section of the power blades, and the reverse rotation thrust formed is also very small. The difference between the forward and reverse rotation thrusts (the horizontal energy of the sea wave) will drive the transmission shaft to rotate continuously. Thereby realizing the function of converting the unidirectional sea wave horizontal energy into mechanical rotation energy.

[0080] The number of omnidirectional ocean current wave horizontal energy collectors, water pump structures and water suction pipes 7 in this embodiment is at least two, and the number is set according to the area where energy needs to be obtained. Each water suction pipe 7 is connected to the high-pressure water delivery pipe 2. The mechanical rotation energy generated by each collector drives the tympanic membrane box pump 32 to operate through the crankcase 33, thereby pressurizing the seawater into high-pressure water. The system collects the high-pressure water into the high-pressure water pipe network for unified output and utilization.

[0081] See also Fig. 20 The sea wave energy collection system of the present invention comprises a high-pressure hydro-turbine generator 10 and a sea wave energy collection system, wherein the water outlet of the high-pressure water pipe network 1 corresponding to the sea wave energy collection system is connected to the high-pressure hydro-turbine generator 10, and at least two high-pressure hydro-turbine generators 10 are provided, both of which are arranged on the shore, and the total installed capacity is set to 1.2 times of the maximum water inflow.

[0082] The sea wave energy power generation system of the present invention, by setting a high-pressure hydro-turbine generator 10 on the shore, can utilize the high-pressure water output type sea wave vertical energy collection system a, the mechanical rotation output type sea wave vertical energy collection system b, the unidirectional sea current sea wave horizontal energy collection system c, and the omnidirectional sea current sea wave horizontal energy collection system d to collect energy and convert it into high-pressure water, which is then transported to the high-pressure hydro-turbine generator 10 and converted into electrical energy for use.

[0083] Preferably, an automatic solenoid valve 11 is provided on the high-pressure water pipe network 1 on one side of the high-pressure hydro-generator 10. The automatic solenoid valve 11 monitors the pressure of the high-pressure water pipe network 1. When the pressure is lower than the set value, one of the solenoid valves and the generator is automatically turned off. When the pressure is higher than the set value, one of the solenoid valves and the generator is automatically turned on. The pressure of the high-pressure water pipe network fluctuates stably within a small set range to ensure high-quality power generation.

[0084] Preferably, a diaphragm pressure stabilizing tank 12 is also provided on the high-pressure water pipe network 1. The diaphragm pressure stabilizing tank 12 is arranged on the shore to assist in stabilizing the pressure of the high-pressure water pipe network 1 and ensure the quality of power generation.

[0085] Preferably, the high-pressure water pipe network 1 is a large-diameter water pipe with a pressure resistance of 9MPa-11MPa, and the diameter of the high-pressure water pipe network 1 is larger than the diameter of the high-pressure water delivery pipe 2. By adopting the high-pressure, large-diameter, and low-flow mode, the energy loss of the entire high-pressure water collection and transportation is reduced to a very low level, and the distance between the energy collection field and the power plant can be greatly increased, even exceeding 10km. It becomes a reality that the power plant is located on the shore and the energy collection field is located in a sea area with high sea wave energy density and far away.

[0086] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
