Description

Technical Field

[0001] The present invention relates to a sea wave energy collection device, and more specifically, to a mechanical rotation output type sea wave vertical energy collector and an energy collection system thereof. Background Art

[0002] The ocean has a huge amount of renewable energy. The collectible energy of the ocean mainly includes sea wave energy and tidal energy. Sea wave energy includes vertical wave energy and horizontal wave energy. Among them, the development and utilization of tidal energy is already very mature. Now the only way for humans to industrially convert ocean energy into electrical energy is tidal power generation. Due to the high energy density energy field required for the development and utilization of sea wave energy, the marine environment is very harsh, and the existing development and utilization of sea wave energy basically remains in the conceptual stage.

[0003] Even tidal power generation is subject to stringent site selection restrictions, and the actual ocean energy that can be utilized is still negligible for human needs. The main reasons why wave energy is difficult to develop and utilize for industrial power generation are:

[0004] 1. The environment is very bad:

[0005] Power plants need a high-energy-density energy collection field. For the ocean, the higher the energy field density, the worse the environment. The ocean's strong winds and waves, turbulent undercurrents, high salt and humidity, and the distance from the coast are all daunting. Such an environment poses great difficulties to the construction, maintenance, and transmission of energy of power plants.

[0006] 2. There is no robust and efficient ocean energy harvesting equipment:

[0007] Existing ocean energy collection equipment is still in the conceptual stage. Without effective energy collection equipment, the industrial utilization of ocean energy is naturally out of the question. Summary of the invention

[0008] The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art. One of its purposes is to provide a mechanical rotation output type sea wave vertical energy collector that can collect the sea wave vertical energy and realize the function of converting the sea wave vertical energy into mechanical rotation energy.

[0009] The second purpose is to provide a mechanical rotation output type sea wave vertical energy collection system to realize the output and utilization of the mechanical rotation energy generated by the collector.

[0010] The first technical solution of the present invention is as follows: a mechanical rotation output type sea wave vertical energy collector, including a power duckweed and a vertically arranged push-pull rod, positioning pulleys are provided above and below the push-pull rod, a transmission shaft is provided on one side of the push-pull rod, the middle part of the push-pull rod is connected to the power duckweed, both ends of the push-pull rod are connected to steel cables, the transmission shaft is connected to a sprocket through a one-way wheel, a chain is sleeved on the sprocket, and the two steel cables pass through the positioning pulleys and are connected to the two ends of the chain respectively.

[0011] As a further improvement, the power duckweed is a flat structure, and the power duckweed is a plastic box shell.

[0012] Furthermore, the power duckweed is provided with a plurality of cross-arranged annular ribs and radial ribs.

[0013] Furthermore, duckweed steel caps for clamping the power duckweed are provided on the upper and lower sides thereof, the push-pull rods respectively penetrate the duckweed steel caps and the power duckweed, and the push-pull rods and the duckweed steel caps are connected by connecting bolts.

[0014] Furthermore, a non-circular anti-rotation rib is provided on the side of the duckweed steel cap close to the power duckweed, and correspondingly, anti-rotation slots matching the anti-rotation rib are provided on the upper and lower sides of the power duckweed, and the anti-rotation rib is clamped in the anti-rotation slot.

[0015] Furthermore, the connection between the push-pull rod, the power duckweed and the duckweed steel cap is a square structure.

[0016] Furthermore, it also includes a guide seat, and the push-pull rod is slidably inserted in the guide seat.

[0017] Technical solution 2 of the present invention is as follows: a mechanical rotation output type sea wave vertical energy collection system, comprising a water pump structure and a mechanical rotation output type sea wave vertical energy collector as described in any one of claims 1-7, wherein the transmission shaft corresponding to the mechanical rotation output type sea wave vertical energy collector is linked to the water pump structure, and the water pump structure is connected with a water suction pipe and a high-pressure water delivery pipe.

[0018] As a further improvement, the water pump structure includes a tympanic box pump and a crankcase, the transmission shaft is linked to the input end of the crankcase, the output end of the crankcase is linked to the tympanic box pump, the suction pipe and the high-pressure water pipe are both connected to the tympanic box pump, and a one-way valve is provided at the end of the high-pressure water pipe.

[0019] Furthermore, at least two of the mechanical rotation output type sea wave vertical energy collectors are connected in parallel on the transmission shaft.

[0020] Beneficial Effects

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. The mechanical rotation output type sea wave vertical energy collector of the present invention, by setting power duckweed and push-pull rods, adopts thin power duckweed to contact the sea wave surface, can make a rapid full-load response to the change of the vertical height of the sea wave surface. When the sea wave surface rises, under the pull of the buoyancy of the power duckweed, the push-pull rod moves upward and drives the lower chain to move through the steel cable, thereby driving the sprocket to rotate clockwise, and the sprocket further drives the transmission shaft to rotate clockwise through the one-way wheel; when the sea wave surface drops, under the pull of the buoyancy of the power duckweed, the push-pull rod moves downward and drives the upper chain to move through the steel cable, thereby driving the sprocket to rotate counterclockwise, but will not drive the transmission shaft to rotate counterclockwise, so that the reciprocating cycle realizes the one-way transmission function of the transmission shaft to avoid the unfavorable situation that the rotation directions conflict with each other when one transmission shaft is connected in parallel with multiple collectors. At the same time, the vertical energy of the sea waves can be collected to realize the function of converting the vertical energy of the sea waves into mechanical rotation energy.

[0023] 2. 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 a unidirectional rotating transmission shaft by setting a water pump structure. The unidirectional rotating transmission shaft drives the tympanic membrane box pump to operate through the crankcase, thereby pressurizing the seawater into high-pressure water and collecting the high-pressure water into the high-pressure water pipe for unified output and utilization.

DETAILED DESCRIPTION

[0033] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0034] See also Figure 1-7 The mechanical rotation output type sea wave vertical energy collector of the present invention comprises a power duckweed 1 and a vertically arranged push-pull rod 2. The power duckweed 1 is placed on the sea wave surface and is a flat structure. It is a plastic box shell and can float up and down with the sea wave surface. Its flat box structure can greatly increase the contact area between the power duckweed 1 and the sea wave surface, and the reaction is more sensitive. Positioning pulleys 3 are provided above and below the push-pull rod 2, and a transmission shaft 4 is provided on one side of the push-pull rod 2. Both ends of the transmission shaft 4 are connected with bearing seats to facilitate the installation of the transmission shaft 4, and the bearing seats can be installed on the seabed. On the seabed, in this embodiment, three positioning pulleys 3 are provided, and a rectangle is formed between the axis connecting the three positioning pulleys 3 and the transmission shaft 4. The middle part of the push-pull rod 2 is connected to the power duckweed 1. The floating power duckweed 1 can push the push-pull rod 2 to move up and down. Both ends of the push-pull rod 2 are connected with steel cables 5. The transmission shaft 4 is connected with a sprocket 6 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 one-way rotation of the transmission shaft 4. A chain 7 is provided on the sprocket 6, and two steel cables 5 pass through the positioning pulley 3 and are connected to the two ends of the chain 7 respectively.

[0035] The mechanical rotation output type sea wave vertical energy collector of the present invention, by setting the power duckweed 1 and the push-pull rod 2, adopts the thin power duckweed 1 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 1, the push-pull rod 2 moves upward and drives the lower chain 7 to move through the steel cable 5, thereby driving the sprocket 6 to rotate clockwise, and the sprocket 6 further drives the transmission shaft 4 to rotate clockwise through the one-way wheel; when the sea wave surface drops, under the pull of the buoyancy and self-weight of the power duckweed 1, the push-pull rod 2 moves downward and drives the upper chain 7 to move through the steel cable 5, thereby driving the sprocket 6 to rotate counterclockwise, but will not drive the transmission shaft 4 to rotate counterclockwise, so that the reciprocating cycle realizes the one-way transmission function of the transmission shaft 4 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 sea wave vertical energy can be collected to realize the function of converting the sea wave vertical energy into mechanical rotation energy.

[0036] Preferably, a plurality of cross-arranged annular ribs 8 and radial ribs 9 are provided in the power duckweed 1, which effectively improves the structural strength of the power duckweed 1 and thus prolongs its service life.

[0037] Preferably, duckweed steel caps 10 are provided on the upper and lower sides of the power duckweed 1 to clamp it. The duckweed steel caps 10 are integral steel components with better structural strength. The push-pull rods 2 respectively penetrate the duckweed steel caps 10 and the power duckweed 1, and the push-pull rods 2 and the duckweed steel caps 10 are connected by connecting bolts 11. The power duckweed 1 is clamped and fixed by two duckweed steel caps 10, which is convenient for disassembly and assembly. Compared with the method of directly connecting the push-pull rods 2 and the power duckweed 1 with screws, or directly connecting the duckweed steel caps 10 and the power duckweed 1 with screws, it can avoid opening holes in the power duckweed 1, thereby preventing seawater from entering the power duckweed 1, thereby affecting the sensitivity of the power duckweed 1.

[0038] Preferably, a non-circular anti-rotation rib 12 is provided on the side of the duckweed steel cap 10 close to the power duckweed 1, and correspondingly, anti-rotation slots 13 adapted to the anti-rotation rib 12 are provided on both the upper and lower sides of the power duckweed 1, and the anti-rotation rib 12 is clamped in the anti-rotation slot 13. The duckweed steel cap 10 and the power duckweed 1 are installed by the anti-rotation rib 12 and the anti-rotation slot 13, which can prevent the power duckweed 1 from rotating relative to the push-pull rod 2, reduce the torque of the connecting bolt 11, and thus improve the connection reliability between the power duckweed 1 and the duckweed steel cap 10, and can realize the rapid positioning and installation of the duckweed steel cap 10, and is more convenient for disassembly and assembly.

[0039] Preferably, the connection between the push-pull rod 2 and the power duckweed 1 and the duckweed steel cap 10 is a square structure, which can further prevent the power duckweed 1 from rotating relative to the push-pull rod 2 and achieve rapid alignment of the bolt holes of the push-pull rod 2, making disassembly and assembly more convenient.

[0040] The energy collector in this embodiment also includes a guide seat 14, which can be fixed on the seabed of the seabed. The push-pull rod 2 is slidably inserted in the guide seat 14 to guide the push-pull rod 2 to slide up and down, ensuring that the push-pull rod 2 can drive the steel cable 5 to move and improve the reaction sensitivity.

[0041] like Figure 8As shown, a mechanical rotation output type sea wave vertical energy collection system of the present invention includes a water pump structure and a mechanical rotation output type sea wave vertical energy collector as described in any one of claims 1 to 7, wherein the transmission shaft 4 corresponding to the mechanical rotation output type sea wave vertical energy collector is linked to the water pump structure, and the water pump structure is connected with a water suction pipe 15 and a high-pressure water delivery pipe 16, wherein the water suction pipe 15 extends to the bottom of the sea water. Specifically, the water pump structure includes a tympanic membrane box pump 17 and a crankcase 18, wherein the transmission shaft 4 is linked to the input end of the crankcase 18, the output end of the crankcase 18 is linked to the tympanic membrane box pump 17, the water suction pipe 15 and the high-pressure water delivery pipe 16 are both connected to the tympanic membrane box pump 17, and a one-way valve 19 is provided at the end of the high-pressure water delivery pipe 16 to prevent the high-pressure water from flowing back.

[0042] 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 4 by setting a water pump structure. The unidirectional rotating transmission shaft 4 drives the tympanic box pump 17 to operate through the crankcase 18, thereby pressurizing the seawater into high-pressure water and collecting the high-pressure water into the high-pressure water pipe 16 for unified output and utilization.

[0043] Preferably, at least two mechanical rotation output type sea wave vertical energy collectors are connected in parallel on the transmission shaft 4, so as to cover a wider range and collect more energy.

[0044] 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.
