Description

Technical Field

[0001] The present invention relates to the field of ships, and in particular to a semi-submersible ship for driving power generation and piling with sea energy. Background Art

[0002] Semi-submersible vessels, also known as semi-submersible mother ships, adjust their ballast water to submerge their cargo decks in the water so that specific cargo (such as barges, yachts, ships, drilling platforms, etc.) to be transported can float from a designated location onto the cargo deck of the semi-submersible vessel and transport the cargo to the designated location. However, current semi-submersible vessels basically use traditional internal combustion engines to drive propellers for navigation, and the fuel used by internal combustion engines needs to be replenished in a timely manner, which places extremely high demands on the supply of ships. Once encountering stormy weather, it will be difficult to carry out marine supply.

[0003] When traditional pile-driving ships are driving piles at sea, the depth of the ship's hull in the water is not deep. Once encountering strong winds and waves, the hull will shake greatly and the piling operation cannot be carried out. Therefore, the operation of traditional pile-driving ships is greatly affected by the weather at sea. The piling equipment of traditional pile-driving ships comes from internal combustion engines, and the piling process consumes a lot of energy and takes a long time. Fuel and other materials need to be frequently transported to the pile-driving ships by other supply ships. However, the conditions at sea are unpredictable, and the replenishment time of the supply ship is easily delayed by the weather, and the replenishment cost is high.

[0004] The ocean has a huge amount of renewable energy, and the energy that can be collected from the ocean mainly includes wave energy, tidal energy, wind energy, etc. It has always been the goal of mankind to use the ocean's own energy to sail. Sailboats have mature technology and a long history, but it is rare to see even theoretical research on ships that use other renewable energy sources in the ocean except wind energy to sail. Since the energy density of wind energy is too small, sailboats need huge sails to drive and are greatly affected by the size of the wind, so they cannot actively drive quickly. Therefore, sailboats can no longer meet the requirements of modern marine transportation and can only be used in a very small amount for sports or tourism.

[0005] In addition, the current propulsion system for ships is basically a propeller propulsion system. However, the propeller propulsion system has the following problems when in use: 1) There is a problem of seawater entering the engine room along the transmission shaft; 2) Fuel and engines are required, which are costly and polluting, and the engine is noisy. When the propeller stirs the water flow, the water flow collides with the hard surface of the propeller, which also produces a lot of noise; 3) When a ship using a traditional fuel propeller propulsion system is moving, a water level difference will be formed between the bow and the stern, with the bow high and the stern low. The greater the speed, the greater the water level difference, forming the so-called uphill effect; at the same time, the bow will be raised, causing the projected area of ​​water resistance to increase and aggravating the turbulence of the ship. Summary of the invention

[0015] Beneficial Effects

[0016] Compared with the prior art, the advantages of the sea energy driven power generation piling semi-submersible vessel of the present invention are:

[0017] 1. Since the ups and downs of sea waves have little effect on the hull below the sea surface, when pile driving is needed, most of the ship should be submerged below the sea surface first. At this time, the hull is stable and not easy to shake with the waves. At this time, pile driving operations can be carried out with high accuracy to ensure that pile driving can be carried out normally.

[0018] 2. Use the ocean current and wave energy collector and the pumping and pressurizing device to pump up seawater and generate high-pressure water to generate electricity. The electricity can be used to power the pipe pile driver directly or indirectly through batteries. The pipe pile driver does not need to be provided with kinetic energy by a fuel engine, which is energy-saving and environmentally friendly. In addition, the ocean current and wave energy collector can continuously collect ocean current and wave energy to ensure the continuous progress of piling, greatly speeding up the progress of the operation.

[0019] 3. High-pressure water is mainly generated by the ocean current and wave energy collector and the pumping and pressurizing device, which makes full use of the energy of ocean current and wave to generate high-pressure water, without or reducing the use of other energy sources, and has good energy-saving effect. Among them, the power duckweed can rise and fall with the waves to generate power, and drive the first piston cylinder structure to extract seawater and pressurize it; while the horizontal current can drive the ocean current drive wheel submerged below the sea surface to rotate, and drive the tympanic box pump to pump seawater and pressurize it. The pressurized seawater can be supplied to the high-pressure jet nozzle and the hydropower generation system respectively as needed. Due to the huge energy of ocean current and wave, especially under the conditions of strong winds and waves, a large amount of energy can be collected by the ocean current and wave energy collector as the driving energy and power generation of the semi-submersible ship, basically without the use of fuel, and no need to refuel at sea, which can greatly extend the single voyage time, which is conducive to the long-term operation of the semi-submersible ship at sea, and solves the extremely difficult special needs of island power supply, sea surface operation power supply, marine foundation piling construction, etc., making the development and utilization of the ocean and islands easier and more efficient.

[0020] 4. Since the reaction force of high-pressure water sprayed by the high-pressure jet nozzle is used to propel the ship forward, the collision between the high-pressure jet and the seawater is a collision between liquids, and the noise generated is greatly reduced compared to the collision between liquids and propellers. In addition, since the total water intake is located at the front of the ship and the high-pressure jet nozzle is located at the rear of the ship, the water intake at the bow will lower the water level at the bow, and the water spray at the stern will raise the water level at the stern, forming the so-called downhill effect, which offsets the uphill effect formed by the hull being pushed forward in the water, reducing the projected area of ​​water resistance and reducing the ship's rocking, thereby making the ship travel smoothly and energy-saving.

[0021] 5. The use of high-pressure jet nozzles eliminates the problem of seawater entering the engine room along the drive shaft of the traditional propeller propulsion system.

[0022] 6. The steering mechanism can drive the high-pressure jet nozzle to swing and realize the steering of the ship. Compared with the traditional propeller that needs to cooperate with the rudder to turn, the rotatable high-pressure jet nozzle does not need to use the rudder additionally.

[0023] 7. When the sea surface is relatively calm and the energy collected by the ocean current and wave energy collector is less than that required to drive the ship, the motor can be used to drive a large-stroke reciprocating pump to extract seawater for pressurization and deliver it to the high-pressure jet nozzle to ensure that the ship has sufficient power to sail in all situations. As an auxiliary power that is only activated in special circumstances, the active power system can be smaller and easier to arrange.

[0047] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0048] Example

[0049] The specific embodiments of the present invention are as follows Figures 1 to 21 As shown, a semi-submersible ship for driving sea energy for power generation and piling includes a ship 22 and a hydropower generation system. The ship 22 is provided with a sea current and sea wave energy collector and a pumping and pressurizing device which are linked in sequence, and is also provided with a total water intake port 13. The input end of the pumping and pressurizing device is connected to the total water intake port 13, and the output end of the pumping and pressurizing device is connected to a second high-pressure pipe 43, and the second high-pressure pipe 43 is connected to the hydropower generation system. The ship 22 is provided with a pipe pile driver 48 and a pile stabilizing clamp 45 which are arranged up and down respectively. The hydropower generation system is electrically connected to the pipe pile driver 48.

[0050] The pile driving stabilizing clamp 45 comprises a stabilizing clamp support 451 , and the stabilizing clamp support 451 is connected to at least two surrounding clamps through a spacing adjustment mechanism, and each clamp is provided with at least one pair of balls 457 .

[0051] The chuck includes a movable clamping rod 456, and a ball 457 is installed on the movable clamping rod 456 through a ball gland 458. The spacing adjustment mechanism includes an adjusting screw 452 that is rotatably connected to a stable clamping support 451, and an operating part and a first thread segment 453 and a second thread segment 454 with opposite thread directions are provided on the adjusting screw 452. The operating part is a hand wheel, and it can also be a motor. Two movable clamping rods 456 arranged opposite to each other are respectively threadedly connected to the first thread segment 453 and the second thread segment 454 at both ends. In this embodiment, there are four adjusting screws 452, four stable clamping supports 451 are arranged along the four corners of a square, and there are also four movable clamping rods 456. The pile body 46 is clamped between the movable clamping rods 456, and the side wall of the pile body 46 contacts the ball 457, so that the pile body 46 can rotate and move up and down, ensuring that when the pile is started, the pile body of the pile body 46 will not be easily blown off by the sea current, and the pile driving is more stable and smooth. The two pairs of vertical movable clamping rods 456 are staggered in the upper and lower directions.

[0052] The sea energy driving power generation piling semi-submersible ship also includes a high-pressure jet nozzle 24. The output end of the pumping and pressurizing device is also connected to a first high-pressure pipe 25, and the first high-pressure pipe 25 is connected to the high-pressure jet nozzle 24. The main water inlet 13 and the high-pressure jet nozzle 24 are respectively arranged at the front and rear of the ship 22. The round pipe of the main water inlet 13 is pinned from both sides and welded with a protective net 28 to keep the water inlet smooth and not easily blocked.

[0053] The cross-sectional area of ​​the jet tail nozzle of the high-pressure jet nozzle 24 is significantly smaller than that of the high-pressure water pipe, so as to ensure the high jet speed and low flow of the jet tail nozzle. At the same time, the high-pressure water pipe network system realizes high water pressure, large pipe diameter, low flow rate and low energy consumption.

[0054] The hydropower generation system includes at least two parallel second high-pressure branch pipes 44, the input end of the second high-pressure branch pipe 44 is connected to the output end of the second high-pressure pipe 43, and each second high-pressure branch pipe 44 is sequentially connected with a second automatic solenoid valve 403, a high-pressure water turbine generator 402 and a second drain 401 along the water flow direction. The high-pressure water turbine generator 402 is connected to a battery, which is used to store the electric energy generated by the high-pressure water turbine generator 402 for backup. The pipe pile driver 48 can be directly powered by the high-pressure water turbine generator 402, or it can be powered by a battery.

[0055] The ship 22 is rectangular in plan and generally divided into four floors, including a diving chamber 37, an equipment support 38, a functional room 39 and a ship roof 40 connected in sequence from bottom to top. The floors are connected by a steel staircase 42.

[0056] The submersible chamber 37 comprises a water-pressurized chamber 371 and a watertight chamber 372 arranged outside the water-pressurized chamber 371. The submersible chamber 37 is basically a rectangular box body surrounded by steel plates, and the box body is reinforced and separated by a plurality of longitudinal and transverse partition steel plates.

[0057] The middle of the diving chamber 37 is provided with a plurality of pressure water chambers 371 arranged in sequence in front and back, and each pressure water chamber 371 is connected together through a connecting port at the bottom. The sinking and floating of the semi-submersible vessel is adjusted by pumping or injecting water into the pressure water chamber 371. The pressure water chamber 371 is provided with a water pump and a vent. The surrounding of the diving chamber 37 is provided with a watertight chamber 372, which is completely closed to provide a certain fixed buoyancy for the semi-submersible vessel. The main water inlet 13 is provided at the front end of the diving chamber 37.

[0058] The diving chamber is the foundation of the upper three-layer structure, with two rows of columns on it. Two rows of vertical sea wave energy collectors are arranged along the outer side of the long side of the diving chamber, and the omnidirectional sea current sea wave energy collectors are arranged in two rows to balance with the two rows of vertical sea wave energy collectors and are arranged below them. They do not interfere with each other when working. The omnidirectional sea current sea wave energy collectors are submerged below the sea surface, and the vertical sea wave energy collectors are located on the sea surface.

[0059] The pipe pile driver 48 is arranged on the ship roof 40, and the pile stabilizing clamp 45 is arranged on the submersible chamber 37. A crane 47 is also arranged on the ship roof 40, which is responsible for various lifting tasks during the pile driving process. The pipe pile driver 48 and the pile stabilizing clamp 45 are arranged in the middle of the ship 22 to ensure that the hull and the pile are not easily eccentric during pile driving, and to minimize the occurrence of unfavorable situations such as the hull tilting and the pile being subjected to bending pressure during pile driving.

[0060] A platform construction hole 221 is provided on the submersible chamber 37 at a position corresponding to the pile stabilizing clamp 45. The platform construction hole 221 passes through the submersible chamber 37 from top to bottom. The submersible chamber 37 is provided with a ship-pile separation door 222 corresponding to the platform construction hole 221. When the ship-pile separation door 222 is opened, the pile body 46 can pass through the platform construction hole 221.

[0061] The ocean current and sea wave energy collector is arranged on the equipment support layer 38. The equipment support layer 38 is mainly used to fix the energy collector and reinforce the column. The equipment support layer 38 is hollowed out as a whole: when anchored for power generation or sailing at a slow speed and supplying power to the outside, the entire layer is submerged in the water to collect ocean energy, and a small part of the high-pressure water generated by the energy collector is used for driving, and the remaining high-pressure water is used for power generation; when sailing at normal speed (rated speed), about two-thirds of the layer is submerged in the water to collect ocean energy, reduce resistance and reduce the impact force on the two rows of vertical sea wave energy collectors. Most of the high-pressure water generated by the energy collector is used for driving, and the remaining high-pressure water is used to generate electricity for self-use; in special circumstances where full floating is required, the entire layer floats to the surface. The stored electricity is used to drive a large-stroke reciprocating pump to generate high-pressure water, which actively drives the ship forward.

[0062] The main body of the functional room 39 is a frame steel structure with a steel plate surface. Among them, the machine room is used to house the high-pressure water power generation system and the high-pressure jet drive system; the distribution room is used to house the high and low voltage power transformation and distribution equipment; the power storage room is used to house the power storage equipment; the living quarters include the kitchen, bathroom, dormitory, etc.; the driving and control room is the driving cabin, and is used to house related control equipment.

[0063] The main body of the ship roof 40 is a frame steel structure with steel plates laid on the surface.

[0064] The ocean current and sea wave energy collector includes a sea wave vertical energy collector, and the pumping and pressurizing device includes a first piston cylinder structure 30. The sea wave vertical energy collector includes a power duckweed 29, which is connected to the first piston connecting rod structure 302 of the first piston cylinder structure 30. The input end of the first cylinder 301 of the first piston cylinder structure 30 is connected to the total water suction port 13 through a one-way valve, and the output end of the first cylinder 301 is connected to a pressure-stabilizing tank 16 through a one-way valve, and the one-way valve can prevent seawater from flowing back. The pressure-stabilizing tank 16 is connected to the first high-pressure pipe 25 and the second high-pressure pipe 43 respectively. There are multiple power duckweeds 29 and they are arranged at the edge of the ship 22. The vertical projection of the power duckweed 29 is circular, and its diameter is much larger than its thickness. It has a large contact area when lifted by the sea waves, and its own weight is relatively light. It reacts sensitively when rising and falling with the sea waves, and has a high energy conversion rate.

[0065] The ocean current and sea wave energy collector includes an ocean current and sea wave horizontal energy collector, and the water pumping and pressurizing device includes a tympanic box pump 36, and the tympanic box pump 36 is installed in a functional room 39. The ocean current and sea wave horizontal energy collector includes an ocean current driving wheel 35 connected to a transmission shaft 34. The ocean current driving wheel 35 includes a wheel frame 351, and at least two power rotors 352 are distributed circumferentially around the transmission shaft 34 on the wheel frame 351. In this embodiment, the number of power rotors 352 is 6. The power rotor 352 is rotatably connected to the wheel frame 351 through a rotor support rod 353, and the rotor support rod 353 passes horizontally through the middle of the front section of the power rotor 352. A first rotor limiting structure 355 is provided between the wheel frame 351 and the power rotor 352, which limits the rotation angle of the power rotor 352 when the power rotor 352 rotates to the point where the front end of the power rotor 352 faces outward and the rear end is adjacent to the transmission shaft 34. The wheel frame 351 is also provided with a second rotor limiting structure 354 for limiting the rotation angle of the power rotor 352 when the power rotor 352 rotates to the point where the rear end of the power rotor 352 faces outward.

[0066] In this embodiment, the transmission shaft 34 is arranged vertically, and the current driving wheel 35 is an omnidirectional current driving wheel, that is, no matter which direction the current flows in the horizontal direction, the omnidirectional current driving wheel can be driven to rotate. Specifically, when the current passes through the omnidirectional current driving wheel, the power rotor blades 352 on the current driving wheel 35 and located on one side of the transmission shaft 34 along the current direction have their front ends facing outward and their rear ends adjacent to the transmission shaft under the action of the current. At this time, the power rotor blades 352 in this state are supported by the first rotor blade limiting structure 355, and the current acts on the first rotor blade surface of the power rotor blades 352 on this side to generate a forward rotation thrust; while the power rotor blades 352 on the other side of the transmission shaft 34 float up under the action of the current, are not supported by the first rotor blade limiting structure 355, and their deployment direction is basically parallel to the current direction, so that the front cross-section of the power rotor blades 352 is minimized, the resistance to the current is small, and the reverse rotation thrust formed thereby is also very small. The difference between the forward and reverse rotation thrusts (the horizontal energy of the sea waves) will drive the transmission shaft 34 to rotate continuously, thereby realizing the function of converting the omnidirectional sea wave horizontal energy into mechanical rotation energy, which is suitable for areas where the direction of the ocean current changes frequently. This structure does not need to consider the relative height between the sea surface and the omnidirectional ocean current driving wheel. The omnidirectional ocean current driving wheel is completely immersed in the sea water, and power can still be generated by the ocean current. In addition, the transmission shaft 34 can also be set horizontally, and the ocean current driving wheel 35 is set in a culvert connected at the front and rear ends. The seawater flowing into the culvert can drive the ocean current driving wheel 35 to rotate. This type of ocean current driving wheel 35 is a unidirectional ocean current driving wheel.

[0067] The transmission shaft 34 is fixedly connected to the wheel frame 351 and is linked to the tympanic membrane box pump 36. The input end of the tympanic membrane box pump 36 is connected to the main water suction port 13. The output end of the tympanic membrane box pump 36 is connected to the pressure-stabilizing tank 16 through a one-way valve. The pressure-stabilizing tank 16 is connected to the first high-pressure pipe 25 and the second high-pressure pipe 43 respectively.

[0068] The high-pressure jet nozzle 24 is connected to a steering mechanism 27. The high-pressure jet nozzle 24 is connected to the first high-pressure pipe 25 through a hose 26. The ship 22 includes a nozzle bracket 23, which is formed by connecting a plurality of channel steels by screws. A nozzle rotating shaft 241 is provided in the middle of the high-pressure jet nozzle 24, and the nozzle rotating shaft 241 is rotatably connected to the nozzle bracket 23. The nozzle bracket 23 is installed at the tail of the diving chamber 37.

[0069] The steering mechanism 27 includes a matching cable 271 and a guide pulley 272, the guide pulley 272 is mounted on the nozzle bracket 23, and both ends of the cable 271 are linked with the high-pressure jet nozzle 24. In addition, a cable limit sleeve 275 is installed on the nozzle bracket 23, and the cable 271 passes through the cable limit sleeve 275. The cable 271 is linked with the steering wheel in the cabin.

[0070] A circular plate 273 is connected between the two ends of the cable 271, and a strip slide 274 is provided on the plate 273, and the length of the strip slide 274 is parallel to the center line of the ship 22. A lever 242 is provided on the front section of the high-pressure jet nozzle 24, and the lever 242 is slidably matched with the strip slide 274. When the cable 271 pulls the plate 273 to move left and right relative to the ship, the lever 242 moves left and right with the strip slide 274, and moves forward and backward relative to the strip slide 274, thereby driving the high-pressure jet nozzle 24 to swing, so that the jet direction is at an angle relative to the center line of the ship 22, and steering is achieved.

[0071] The high-pressure jet nozzle 24 is connected to a first flow control solenoid valve 20. The first flow control solenoid valve 20 is connected to a controller, and the jet flow rate can be adjusted by adjusting the opening of the first flow control solenoid valve 20, thereby adjusting the ship speed.

[0072] A long-stroke reciprocating pump 15 is also provided in the functional room 39 of the semi-submersible ship for driving and generating electricity of sea energy. The input end of the long-stroke reciprocating pump 15 is connected to the main water suction port 13, and the output end of the long-stroke reciprocating pump 15 is connected to the first high-pressure pipe 25. The long-stroke reciprocating pump 15 includes a basic component, which includes a matching second cylinder body 1 and a piston connecting rod structure 2. One end of the second cylinder body 1 is connected to a water suction port 7 through a first one-way valve 71, and is connected to a high-pressure water outlet 8 through a second one-way valve 81. The water suction port 7 is connected to the main water suction port 13. The long-stroke reciprocating pump 15 also includes a meshing transmission rack slider 3 and a gear 4, the gear 4 is connected to a power shaft 41, and the transmission rack slider 3 is connected to the piston connecting rod structure 2. Among them, the water suction port 7 is located on the side wall of the second cylinder body 1 near the lower end, and the high-pressure water outlet 8 is located at the lower end of the second cylinder body 1. The second cylinder body 1 is arranged vertically.

[0073] A third one-way valve 17 is connected between the high-pressure water outlet 8 and the first high-pressure pipe 25. An automatic solenoid valve 18 is connected to the first high-pressure pipe 25, and the automatic solenoid valve 18 is connected to the controller.

[0074] The transmission rack slider 3 includes a slider body 31, on which a ring-shaped meshing rack 32 is arranged, and the meshing rack 32 is meshed with the gear 4. The meshing rack 32 includes two linear meshing racks 321 arranged oppositely and vertically, and the linear meshing racks 321 are parallel to the piston connecting rod structure 2. The upper and lower ends of the two linear meshing racks 321 are connected by an arc-shaped transition rack 322. The basic component also includes a slider guide frame 6, and a guide structure is provided between the slider guide frame 6 and the transmission rack slider 3 to keep the meshing rack 32 and the gear 4 in mesh. The transmission rack slider 3 is movably connected to the piston connecting rod structure 2.

[0075] In this embodiment, the slider guide frame 6 includes a base plate 61. The guide structure includes a strip-shaped guide plate 62 and a positioning slide pin 33 that can move around the outer side wall of the guide plate 62. The strip-shaped guide plate 62 is arranged vertically, and its upper and lower ends are arranged in an arc shape. The guide plate 62 is arranged on the side of the base plate 61, and the positioning slide pin 33 is arranged on the side of the slider body 31. The guide plate 62 and the positioning slide pin 33 are two groups, respectively located on both sides of the bite rack 32. Both sides of the base plate 61 are provided with welding ports 63 and auxiliary welding plates 64, and the auxiliary welding plates 64 are welded to the side of the slide rail 5.

[0076] The piston connecting rod structure 2 is provided with a transversely arranged first connecting rod 21, and the first connecting rod 21 is transversely slidably connected to the slider body 31. The slider body 31 is transversely slidably connected to the second connecting rod 9. The basic assembly also includes a slide rail 5 connected to the second cylinder body 1, and the sliding blocks at both ends of the second connecting rod 9 are slidably connected to the slide rail 5. In this embodiment, the first connecting rod 21 and the second connecting rod 9 are respectively located at the upper and lower ends of the slider body 31.

[0077] Each basic assembly is provided with two second cylinder bodies 1, which are symmetrically arranged on both sides of the gear 4, without eccentricity, ensuring smooth operation and durable use of the reciprocating pump. The two ends of the first connecting rod 21 are respectively connected to the upper ends of the piston connecting rod structures 2 of the second cylinder bodies 1 on both sides.

[0078] The number of basic components is an even number such as 2, 4, 6, etc., and the cylinder strokes of the piston-connecting rod structures 2 in the two corresponding basic components are set in reverse phase. In this embodiment, the number of basic components is 2. When the two piston-connecting rod structures 2 of one basic component are in a fully pulled-out state, the two piston-connecting rod structures 2 of the other basic component are in a fully pressed-in state. There is one power shaft 41, and the number of gears 4 corresponds to the number of basic components. In each basic component, two symmetrically arranged ribs 65 are provided on the rear side of the base plate 61 of the slider guide frame 6. The ribs 65 of the two basic components are arranged oppositely and fixedly connected by the connecting plate 10. In addition, the second cylinder body 1 of each basic component is fixed together by a fixing bracket 11, thereby ensuring the stability of the entire large-stroke reciprocating pump.

[0079] During operation, the drive motor 12, the automatic transmission 14 and the power shaft 41 are linked in sequence to drive the power shaft 41 and the gear 4 to rotate in one direction. The drive motor 12 can be powered by the battery of the ship 22. Since the positioning slide pin 33 always moves around the outer wall of the guide plate 62, it is ensured that the gear 4 is always engaged with the ring-arranged meshing rack 32 on the transmission rack slider 3, so that the transmission rack slider 3 can move back and forth up and down in a large range, and drive the piston connecting rod structure 2 to move up and down. In this process, when the gear 4 passes through the arc-shaped transition rack 322 of the meshing rack 32, the transmission rack slider 3 will also move horizontally relative to the piston connecting rod structure 2, so that the gear 4 can switch between the two straight meshing racks 321, so that the purpose of moving the piston connecting rod structure 2 up and down can be achieved without the need for the gear 4 to reverse the rotation. During the up and down movement of the piston-connecting rod structure 2, when the piston-connecting rod structure 2 moves up, negative pressure is generated in the second cylinder body 1, and seawater is sucked into the second cylinder body 1 through the water suction port 7. At this time, the second one-way valve 81 is closed; when the piston-connecting rod structure 2 moves down, the water pressure in the second cylinder body 1 increases, the first one-way valve 71 is closed, and the second one-way valve 81 is opened. The high-pressure seawater in the second cylinder body 1 is transported from the high-pressure water outlet 8 to the high-pressure pipe 25 of the high-pressure jet drive system of the ship 22, and the high-pressure jet nozzle 24 at the end of the high-pressure pipe 25 sprays water toward the rear of the hull, using the reverse thrust of the water to drive the ship 22 forward.

[0080] When the rated high-pressure water pressure of the jet drive system is 10MPa, and the tail nozzle of the high-pressure jet nozzle 24 is D50, it can be calculated that: its tail jet speed is 100m / s, the maximum thrust is 1.96T, and the maximum water spray volume is 0.196M 3 / s.

[0081] When the rated high-pressure water pressure of the jet drive system is 12MPa, and the tail nozzle of the high-pressure jet nozzle 24 is D100, it can be calculated that: its tail jet speed is 120m / s, the maximum thrust is 9.4T, and the maximum water spray volume is 0.94M 3 / s.

[0082] Generally, the rated pressure of high-pressure water is about 10MPa, and the main power comes from the high-pressure water generated by the sea wave energy collector. The high-pressure water pipe network system has high water pressure, large pipe diameter, low flow rate and low energy consumption.

[0083] The following takes the high-pressure water rated pressure of 10MPa as an example to illustrate the realization process of the two main functions of the sea energy driving and power generation semi-submersible ship:

[0084] (1) Using sea wave energy to generate electricity:

[0085] When moored or sailing, the second deck of the ship is completely submerged in water to collect ocean energy, and the high-pressure water generated by the energy collector is used to drive the high-pressure hydraulic turbine generator to generate electricity.

[0086] Generally, more than three turbine generators are used. When the water pressure is greater than 10.1MPa, an additional turbine generator is automatically opened through the automatic control solenoid valve. When the water pressure is less than 9.9MPa, an automatic control solenoid valve automatically closes a turbine generator, thereby achieving the function of high-quality power generation.

[0087] (2) Using high-pressure water to achieve navigation function:

[0088] The ship is driven by a high-pressure water jet drive system. The high-pressure water mainly comes from the sea wave energy collector. Only in special circumstances will the power storage drive large-stroke reciprocating pump be started to actively replenish the high-pressure water. The thrust of the ship is controlled by controlling the flow rate of the flow control solenoid valve, and the direction of the tail jet is controlled to control the ship's heading, thereby realizing the ship's driving function.

[0089] Implementation of piling function:

[0090] The sea wave energy is used to generate electricity for construction equipment such as pile drivers, cranes, and sludge pumps, and the fourth floor is used as a construction site. The construction process is as follows:

[0091] (1) The semi-submersible vessel floats up, the piles are placed, and the first and third layers of slidable sea surface pile stabilization clamps are adjusted to clamp the piles.

[0092] (2) The semi-submersible vessel sinks to the sea level when it is moored for power generation, adjusts the ship's position so that the piles are aligned with the piling position on the seabed, and starts piling construction.

[0093] (3) After the pile driving is completed, the piles are cut at a slightly higher sea level. The semi-submersible vessel floats up and the ship and piles are separated through the ship-pile separation channel.

[0094] The entire piling process is carried out on water. The self-generation of sea wave energy solves the problem of power energy for offshore construction. The superior stability and free floating characteristics of the semi-submersible vessel fully equipped with sea wave energy collectors enable the piling operation to be carried out smoothly in the stormy sea.

[0095] The present invention has been described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
