Description

Technical Field

[0001] This invention relates to hydrogen production floating platforms, specifically to an offshore wind power hydrogen production floating platform resistant to wind and waves and its stabilization method. Background Technology

[0002] Offshore wind energy resources are abundant. Hydrogen-producing floating platforms utilize wind turbines and other equipment to convert wind energy into electricity, which is then electrolyzed to produce hydrogen—a process that is environmentally friendly. Offshore wind-powered hydrogen-producing floating platforms typically use a multi-point mooring system connected to the seabed foundation. This system can be equipped with portable or fixed anchor winches, and the mooring cables can be anchor chains, steel wire cables (or polyester cables), or a chain-cable-chain structure. However, during strong winds, waves are generated on the sea surface, impacting the floating platform and causing it to sway. While anchor chains connecting to the seabed can prevent significant shifts, they cannot effectively reduce the platform's swaying. Summary of the Invention

[0003] Purpose of the invention: The first purpose of this invention is to provide a stable offshore wind power hydrogen production floating platform that can effectively cope with strong winds and waves; the second purpose of this invention is to provide a method for stabilizing the offshore wind power hydrogen production floating platform.

[0004] Technical Solution: The offshore wind power wave-resistant hydrogen production floating platform of the present invention includes a hydrogen production floating platform, a multi-point mooring system on the hydrogen production floating platform, a fixed plate horizontally installed at the bottom of the hydrogen production floating platform compartment, the fixed plate being perpendicular to the length direction of the hydrogen production floating platform, water tanks fixed at both ends of the top of the fixed plate, the two water tanks being connected by copper pipes and delivery pipes respectively, and a bidirectional pump being installed on the delivery pipes; fixed plates are installed at both ends inside the copper pipes, and movable plates are connected to the inner sides of the fixed plates by springs, the movable plates being made of magnetic material and capable of sliding within the copper pipes; water passage holes are provided on both the fixed plates and the movable plates;

[0005] A support column is fixed at the top center of the fixed plate, and a pendulum is rotatably connected to the support column. Slide grooves are opened on both sides of the support column at the top of the fixed plate, and movable plates are slidably arranged in the slide grooves. A fixed block is set at the end of the slide groove away from the support column, and the movable plate is connected to the corresponding fixed block by a compression spring. A touch switch is fixed on the top of the fixed block. In the initial state, the vertical pendulum is in contact with the two movable plates. When the hydrogen production floating platform tilts, the pendulum pushes the movable plate to trigger the touch switch, so that the bidirectional pump works. The two touch switches trigger the bidirectional pump to pump water in different directions.

[0006] Furthermore, the hydrogen production floating platform is equipped with multi-point mooring systems at both the front and rear ends on both sides.

[0007] Furthermore, balance plates are installed on both sides of the hydrogen production floating platform. The balance plates can increase the contact area between the hydrogen production floating platform and water, thereby further improving the stability of the hydrogen production floating platform.

[0008] Furthermore, there are multiple fixed plates, which are set up as needed along the length of the hydrogen production floating platform.

[0009] Furthermore, the bottom of the hydrogen production floating platform compartment is provided with an opening, in which a suitable counterweight is slidably installed; a support plate is fixed above the opening, and a drive mechanism for driving the counterweight to move up and down is provided on the support plate.

[0010] Furthermore, the drive mechanism includes a motor and a reducer. A sleeve is mounted on the support plate via bearings, and a threaded rod is threadedly connected to the sleeve. A counterweight is connected to the lower end of the threaded rod. A worm gear is fixed to the top of the sleeve. The motor and reducer are fixed on the support plate. The output end of the motor is connected to the input end of the reducer. A worm is connected to the output end of the reducer. The worm is rotatably connected to the support plate via two support blocks and meshes with the worm gear.

[0011] Furthermore, several telescopic rods are evenly connected between the support plate and the counterweight, and each telescopic rod consists of two interlocking, slidable rods.

[0012] Furthermore, the number of openings is multiple, and they are set as needed along the length of the hydrogen production floating platform.

[0013] Furthermore, a gyroscope balancer is installed at the bottom of the hydrogen production floating platform compartment. There are multiple gyroscope balancers, which are installed as needed along the length of the hydrogen production floating platform.

[0014] The gyroscope balancer is existing technology, designed based on the principle of gyroscope and the conservation of angular momentum. This invention utilizes the gyroscope balancer to further improve the stability of hydrogen production floating platforms.

[0015] The stabilization method for the offshore wind power wave-resistant hydrogen production floating platform of the present invention includes:

[0016] When encountering wind and waves, activate the multi-point mooring system;

[0017] When the hydrogen production floating platform tilts to the left, the pendulum pushes the movable plate on the left to trigger the touch switch, and the bidirectional pump starts, transferring water from the left water tank to the right water tank, thereby lowering the center of gravity of the hydrogen production floating platform and improving its stability; the same applies when the hydrogen production floating platform tilts to the right.

[0018] When the hydrogen production floating platform shakes, the motor is started to move the threaded rod downwards, which in turn moves the counterweight downwards, lowering the center of gravity of the hydrogen production floating platform and improving its stability.

[0019] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The present invention uses a multi-point mooring system to fix the hydrogen production floating platform, and at the same time uses a water tank to lower the center of gravity of the hydrogen production floating platform through gravity compensation, thereby improving the stability of the hydrogen production floating platform.

[0030] like Figures 1 to 7As shown, this embodiment of the invention provides a floating platform for hydrogen production in offshore wind power, including a hydrogen production floating platform 1. The hydrogen production floating platform 1 has several compartments inside, and the surface of the hydrogen production floating platform 1 is equipped with a hydrogen production module, a fire protection system, a living quarters, a helicopter platform, a deck crane, a wind turbine, a rectifier, etc.

[0031] The hydrogen production floating platform 1 is fixedly connected to both sides with balance plates 3.

[0032] The hydrogen production floating platform 1 is equipped with multi-point mooring systems 2 at both the front and rear ends on both sides. The multi-point mooring system 2 includes a working box 29 fixedly connected to the surface of the hydrogen production floating platform 1. An anchor winch is installed inside the working box 29. The surface of the working box 29 has through holes 30 through which anchor chains 31 pass.

[0033] A fixed plate 4 is horizontally fixed to the bottom of the hydrogen production floating platform 1, and the fixed plate 4 is arranged perpendicular to the length direction of the hydrogen production floating platform 1. Water tanks 5 are fixed at both ends of the top of the fixed plate 4. The two water tanks 5 are connected by copper pipes 6 and delivery pipes 8, respectively. A bidirectional pump 7 is installed on the delivery pipe 8, and the bidirectional pump 7 is fixedly connected to the top of the fixed plate 4. Fixed plates 9 are installed at both ends inside the copper pipe 6. A movable plate 11 is connected to the inner side of the fixed plate 9 by springs 10. The movable plate 11 is made of magnetic material and can slide in the copper pipe 6. Several water passage holes 12 are provided on both the fixed plate 9 and the movable plate 11 in a ring.

[0034] A support column 13 is fixed at the top center of the fixed plate 4. A pendulum 14 is rotatably connected to the support column 13. Slide grooves are formed on both sides of the support column 13 at the top of the fixed plate 4, and movable plates 15 (with a sliding block structure at the bottom of the movable plates 15 that can slide along the grooves) are slidably disposed within these grooves. A fixed block 16 is provided at the end of the groove furthest from the support column 13, and the movable plates 15 are connected to the corresponding fixed blocks 16 via compression springs 17. In the initial state, the vertical pendulum 14 is in contact with the two movable plates 15. A touch switch 18 is fixed to the top of the fixed block 16, and a controller 19 is fixed to the outside of the left water tank 5. The controller 19 is connected to both the touch switch 18 and the bidirectional pump 7. When the movable plate 15 triggers the touch switch 18, the touch switch 18 controls the bidirectional pump 7 to start via the controller 19.

[0035] The fixing plate 4 and its components form a whole, facilitating installation or disassembly as needed. In this embodiment, the surfaces of the spring 10 and the compression spring 17 are coated with anti-rust paint to protect them. Multiple fixing plates 4 are provided, arranged as needed along the length of the hydrogen production floating platform 1.

[0036] A water inlet pipe 32 is bolted to the top of the water tank 5. Multiple water-retaining rings are installed on the inner wall of the water inlet pipe 32. The water inlet pipe 32 and the water-retaining rings prevent water from overflowing from the water tank 5 when it is shaken. The initial water level of the water tank 5 is approximately three-fifths of its capacity.

[0037] The bottom of the hydrogen production floating platform 1 has an opening, through which a suitable counterweight 22 is slidably mounted. A support plate 20 is fixed above the opening, and a drive mechanism for moving the counterweight 22 up and down is mounted on the support plate 20. Specifically, the drive mechanism includes a motor 27 and a reducer 26. A sleeve 33 is mounted on the support plate 20 via bearings, and a sealed shaft cover made of plastic is installed inside the bearings. A threaded rod 34 (a lead screw structure) is threaded into the sleeve 33, and the lower end of the threaded rod 34 is fixedly connected to the counterweight 22. A worm gear 23 is fixedly connected to the top of the sleeve 33. The motor 27 and the reducer 26 are fixed to the support plate 20. The output end of the motor 27 is connected to the input end of the reducer 26, and the output end of the reducer 26 is connected to a worm gear 25. The worm gear 25 is rotatably connected to the support plate 20 via two support blocks 24 and meshes with the worm gear 23.

[0038] In addition, four telescopic rods 21 connect the support plate 20 and the counterweight 22, and these four telescopic rods 21 are distributed at the four corners of the counterweight 22. Each telescopic rod 21 is specifically two interlocking, slidable rods. In this embodiment, the surface of the counterweight 22 is coated with a corrosion-resistant coating to prevent it from rusting in seawater. There are multiple openings, arranged as needed along the length of the hydrogen production floating platform 1, with each opening corresponding to a specific support plate 20.

[0039] The bottom of the hydrogen production floating platform 1 is equipped with multiple gyroscope balancers 28, which are arranged as needed along the length of the hydrogen production floating platform 1. The gyroscope balancer 28 is existing technology and utilizes the principle of a gyroscope.

[0040] This invention also provides a stabilization method for the offshore wind power wave-resistant hydrogen production floating platform described in this invention, comprising:

[0041] When encountering wind and waves, the multi-point mooring system 2 is activated and the anchor chains 31 are released. By setting up multiple anchor chains 31, the stability of the hydrogen production floating platform 1 is improved, and the hydrogen production floating platform 1 is prevented from shifting significantly.

[0042] By setting up the balance plate 3, when the hydrogen production floating platform 1 sways left and right, the balance plate 3 can increase the contact area between the hydrogen production floating platform 1 and the water, thereby increasing the resistance when the hydrogen production floating platform 1 sways, reducing the swaying of the hydrogen production floating platform 1, and improving the stability of the hydrogen production floating platform 1.

[0043] When the hydrogen production floating platform 1 tilts to the left, the water tanks 5 on both sides are connected by copper pipes 6. According to the principle of communicating vessels, the water in the right water tank 5 will flow into the left water tank 5. During the flow, the water will pass through the water passage 12. The diameter of the water passage 12 is small, which can limit the flow of water. As the water in the copper pipe 6 flows to the left, it also pushes the movable plate 11 to move to the left. Since the movable plate 11 is made of magnetic material, according to Lenz's law, when the movable plate 11 moves in the copper pipe 6, the copper pipe 6 can be regarded as an infinite number of closed loops. If the number of magnetic lines passing through it changes in the closed loop, an induced current will be generated in the closed loop. The induced current and the movable plate 11 generate opposite forces, so that the induced current hinders the movement of the movable plate 11. The movable plate 11 can also restrict the water flow to a certain extent, so as to prevent a large amount of water in the right water tank 5 from flowing into the left water tank 5 in a short period of time when tilting occurs, thereby aggravating the tilt of the hydrogen production floating platform 1. (If the movable plate moves a lot, when the ship tilts, the movable plate will tilt and move quickly with the water flow, which will easily aggravate the tilt of the ship. When the movable plate cannot move quickly, water can only flow slowly through the through holes on the surface of the movable plate, while the bidirectional pump delivers water quickly, thereby reducing the tilt of the ship.) At this time, the tilt of the hydrogen production floating platform 1 will cause the support column 13 to shift, while the center of gravity of the pendulum 14 is always downward. Therefore, the pendulum 14 will push the movable plate 15 on the left, causing the movable plate 15 to trigger the touch switch 18. At this time, the touch switch 18 starts the bidirectional pump 7 through the controller 19, which transports the water in the left water tank 5 to the right water tank 5, thereby increasing the mass of the right water tank 5 and helping the hydrogen production floating platform 1 to reset. The speed at which the bidirectional pump 7 delivers water is much greater than the speed at which water flows in the copper pipe 6, so that when the hydrogen production floating platform 1 tilts to the left, the bidirectional pump 7 automatically delivers water to the right water tank 5, thereby lowering the center of gravity of the hydrogen production floating platform 1 and improving the stability of the hydrogen production floating platform 1.

[0044] Similarly, when the hydrogen production floating platform 1 tilts to the right, the bidirectional pump 7 reverses the flow of water.

[0045] When the hydrogen production floating platform 1 sways, the starter motor 27 rotates, driving the reducer 26. The output of the reducer 26 stably and uniformly drives the worm gear 25 to rotate, which in turn drives the worm wheel 23 to rotate, and then drives the sleeve 33 to rotate. Since the threaded rod 34 is fixedly connected to the counterweight 22, the threaded rod 34 cannot rotate. Therefore, when the sleeve 33 rotates, the threaded rod 34 moves downward, which in turn drives the counterweight 22 to move downward, lowering the center of gravity of the hydrogen production floating platform 1 and improving its stability. Utilizing the principle that the worm gear 25 can drive the worm wheel 23 to rotate, while the worm wheel 23 cannot drive the worm gear 25 to rotate, the position of the counterweight 22 is self-locked.
