Description

Technical Field

[0001] This utility model relates to an offshore platform, and more particularly to an offshore floating hydrogen production platform applied in the field of offshore platforms. Background Technology

[0002] A floating hydrogen production platform is a floating facility that utilizes marine environmental resources (such as seawater, wind power, and solar energy) to produce green hydrogen. It combines water electrolysis hydrogen production technology with a floating platform, producing hydrogen directly at sea by electrolyzing seawater using renewable energy sources (such as wind power, solar power, or wave power). It is a clean energy production device.

[0003] Chinese patent CN214508801U discloses a mobile offshore aquaculture and hydrogen production equipment, including a platform, netting, deck, and hydrogen production facilities. The platform has a polygonal geometry and is a frame-type steel structure composed of several hollow columns, main beams, secondary beams, cross braces, and hollow pads. The length and width of the platform are both greater than its height. This utility model can provide a huge space for aquaculture and cleverly utilize existing offshore wind farms to produce green hydrogen, providing a solution to the problem of offshore wind power utilization.

[0004] Traditional offshore floating platforms mostly use ballast water tanks or independent counterweight sliders to achieve stability adjustment. Ballast water tanks adjust the platform's center of gravity by injecting or discharging seawater. Although this can improve the platform's stability to some extent, its response speed is slow and it is difficult to adapt to rapidly changing sea conditions. Especially when encountering sudden wind and waves, the adjustment lag of ballast water tanks may cause the platform to tilt too much, affecting the normal operation of equipment or even causing safety accidents. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that traditional offshore floating platforms mostly use ballast water tanks or independent counterweight sliders to achieve stability adjustment. Ballast water tanks adjust the platform's center of gravity by injecting or discharging seawater. Although this can improve the stability of the platform to a certain extent, its response speed is slow and it is difficult to adapt to rapidly changing sea conditions.

[0006] To address the aforementioned issues, this utility model provides a floating hydrogen production platform for marine applications, comprising multiple floating platform bodies. Each floating platform body has an underwater support column fixedly connected to its four lower corners. The multiple floating platform bodies are assembled together. An equipment carrying platform is fixedly connected to the upper end of each floating platform body. Multiple electrolysis hydrogen production modules are mounted on the upper end of the equipment carrying platform. An extended stabilization platform is mounted at the lower end of each underwater support column. Multiple elastic buffer connectors are fixedly connected to the upper end of the extended stabilization platform. Multiple hydraulic telescopic drive mechanisms are fixedly connected to the upper end of the extended stabilization platform. An annular dynamic counterweight cover is fixedly connected to the upper end of the multiple elastic buffer connectors. The annular dynamic counterweight cover and the output ends of the hydraulic telescopic drive mechanisms are interconnected. A double-layer annular support frame is fixedly connected to the inner end of the annular dynamic counterweight cover. A spherical counterweight receiving cavity is opened at the inner end of the double-layer annular support frame. Multiple adaptive spherical counterweight blocks are slidably connected to the inner end of the spherical counterweight receiving cavity.

[0007] In the aforementioned floating hydrogen production platform, this solution achieves efficient dynamic balance of the platform under complex sea conditions through the synergistic effect of the annular dynamic counterweight cover, adaptive spherical counterweight block, hydraulic telescopic drive mechanism and elastic buffer connector. It has the advantages of simple structure, fast response speed and high balance accuracy, and is suitable for high-stability operation scenarios such as offshore hydrogen production platforms and floating wind power platforms.

[0008] As a further improvement of this application, multiple elastic buffer connectors are arranged in a ring at equal intervals, and the multiple elastic buffer connectors are located on the sides of multiple hydraulic telescopic drive mechanisms.

[0009] As a further improvement of this application, the inner end of the double-layer annular support frame is provided with a guide limiting protrusion, and multiple spherical counterweight receiving cavities are located between the guide limiting protrusion and the spherical counterweight receiving cavities.

[0010] As a further improvement of this application, the output end of the hydraulic telescopic drive mechanism is provided with a universal joint mechanism, which includes a columnar connecting housing.

[0011] As another improvement of this application, the columnar connecting housing is disposed at the output end of the hydraulic telescopic drive mechanism, and the upper end of the columnar connecting housing is movably connected to a ball joint universal joint.

[0012] As a further improvement to this application, the ball joint universal joint is in contact with the lower part of the annular dynamic counterweight cover, and a high-precision tilt monitoring sensor is fixedly connected to the inner wall of the annular dynamic counterweight cover.

[0013] As a further improvement to this application, the floating platform body is externally connected to a control terminal, and the control terminal is electrically connected to multiple hydraulic telescopic drive mechanisms and high-precision tilt angle monitoring sensors.

[0014] In summary, this solution features an annular dynamic counterweight cover beneath the floating platform, containing multiple adaptive spherical counterweight blocks that can slide freely between the spherical counterweight housing and the guide limiting ring. The sliding trajectory is precisely guided by the guide limiting ring. The tilt angle of the annular dynamic counterweight cover is adjusted by a hydraulic telescopic drive mechanism driven by a controller. This mechanism is connected to the annular dynamic counterweight cover via a universal joint, ensuring stability and reliability. The annular dynamic counterweight cover is connected to the underwater support column via an elastic buffer connector, which deforms to adapt to angle changes. Simultaneously, the adaptive spherical counterweight blocks slide to a lower position under gravity, achieving counterweight balance. A high-precision tilt angle monitoring sensor monitors the tilt angle in real time and feeds it back to the controller for precise control. This solution, through the synergistic effect of the annular dynamic counterweight cover, adaptive spherical counterweight blocks, hydraulic telescopic drive mechanism, and elastic buffer connector, achieves efficient dynamic balance of the platform under complex sea conditions. It boasts advantages such as simple structure, fast response speed, and high balance accuracy, making it suitable for high-stability operating scenarios such as offshore hydrogen production platforms and floating wind power platforms.

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figure 1-6 A floating hydrogen production platform is shown, comprising multiple floating platform bodies 1. Each floating platform body 1 has an underwater support column 2 fixedly connected to its lower four corners. The multiple floating platform bodies 1 are assembled together. An equipment carrying platform 3 is fixedly connected to the upper end of the floating platform body 1. Multiple electrolysis hydrogen production modules 4 are installed on the upper end of the equipment carrying platform 3. An extended stabilization platform 5 is installed at the lower end of the underwater support column 2. Multiple elastic buffer connectors 15 are fixedly connected to the upper end of the extended stabilization platform 5. Multiple hydraulic telescopic drive mechanisms 6 are fixedly connected to the upper end of the extended stabilization platform 5. An annular dynamic counterweight cover 7 is fixedly connected to the upper end of the multiple elastic buffer connectors 15. The output ends of the annular dynamic counterweight cover 7 and the hydraulic telescopic drive mechanisms 6 are interconnected. A double-layer annular support frame 8 is fixedly connected to the inner end of the annular dynamic counterweight cover 7. A spherical counterweight receiving cavity 9 is opened at the inner end of the double-layer annular support frame 8. Multiple adaptive spherical counterweight blocks 10 are slidably connected to the inner end of the spherical counterweight receiving cavity 9.

[0027] Figure 1-6 Multiple elastic buffer connectors 15 are arranged in a ring at equal intervals. The multiple elastic buffer connectors 15 are located on the sides of multiple hydraulic telescopic drive mechanisms 6. The inner end of the double-layer annular support frame 8 is provided with a guide limiting protrusion ring 14. Multiple spherical counterweight receiving cavities 9 are located between the guide limiting protrusion ring 14 and the spherical counterweight receiving cavities 9. A high-precision tilt angle monitoring sensor 16 is fixedly connected to the inner side wall of the annular dynamic counterweight cover 7. The floating platform body 1 is externally connected to a control terminal. The control terminal, multiple hydraulic telescopic drive mechanisms 6 and high-precision tilt angle monitoring sensor 16 are electrically connected to each other.

[0028] Figure 1-6 The floating platform 1 is shown to be firmly fixed to the seabed by strong and corrosion-resistant chains. This fixing method provides basic stability for the floating platform, resists horizontal forces such as ocean currents and tides, and reduces the displacement of the floating platform on the sea surface.

[0029] Then, an annular dynamic counterweight cover 7 is installed below the floating platform body 1, located outside the underwater support column 2. The annular dynamic counterweight cover 7 contains multiple adaptive spherical counterweight blocks 10. These adaptive spherical counterweight blocks 10 are arranged between the spherical counterweight receiving cavity 9 and the guide limiting protrusion ring 14, allowing them to slide freely within the annular space. Their sliding trajectory is precisely guided by the guide limiting protrusion ring 14, ensuring that the adaptive spherical counterweight blocks 10 remain stable during movement. The tilt angle of the entire annular dynamic counterweight cover 7 can be raised or lowered according to actual needs by driving the hydraulic telescopic drive mechanism 6 at the corresponding position via a controller. The telescopic action of the hydraulic telescopic drive mechanism 6 is transmitted to the annular dynamic counterweight cover through the universal joint mechanism 11. The shell 7 and universal connection mechanism 11 include a columnar connecting shell 12 and a ball joint universal joint 13. The fixed end of the annular dynamic counterweight shell 7 is connected to the underwater support column 2 through multiple elastic buffer connectors 15 with follow-deformation capability. The elastic buffer connectors 15 are made of high-strength alloy material and have excellent elastic recovery performance and fatigue resistance. When the hydraulic telescopic drive mechanism 6 adjusts the tilt angle of the annular dynamic counterweight shell 7, the elastic buffer connectors 15 can follow the deformation to adapt to the angle change. At the same time, multiple adaptive spherical counterweight blocks 10 in the annular dynamic counterweight shell 7 automatically slide to the lower position in the tilt direction under the action of gravity to form a counterweight balance, thereby realizing the rapid stabilization of the platform body 1 under complex sea conditions.

[0030] Secondly, a high-precision tilt angle monitoring sensor 16 is installed on the inner wall of the annular dynamic counterweight cover 7. The high-precision tilt angle monitoring sensor 16 monitors the tilt angle of the annular dynamic counterweight cover 7 in real time and feeds the data back to the external controller. The controller precisely adjusts the extension and retraction of the hydraulic telescopic drive mechanism 6 according to the feedback data to ensure that the tilt angle of the annular dynamic counterweight cover 7 is accurate and controllable. The high-precision tilt angle monitoring sensor 16 adopts high-precision technology and can meet the requirements of high-precision balance adjustment.

[0031] This solution achieves efficient dynamic balance of the platform under complex sea conditions through the synergistic action of the annular dynamic counterweight cover 7, the adaptive spherical counterweight block 10, the hydraulic telescopic drive mechanism 6, and the elastic buffer connector 15. It has the advantages of simple structure, fast response speed, and high balance accuracy. At the same time, the closed-loop control of the high-precision tilt angle monitoring sensor 16 and the controller further improves the stability and reliability of the system. It is suitable for floating facilities that require high stability operation, such as offshore hydrogen production platforms and floating wind power platforms. In addition, the annular dynamic counterweight cover 7 of this solution is made of lightweight composite material, which has excellent corrosion resistance and fatigue resistance, and can operate stably for a long time in harsh marine environments. The surface of the adaptive spherical counterweight block 10 is specially treated with an extremely low coefficient of friction, ensuring that it will not get stuck or wear during sliding, further improving the reliability and service life of the system.

[0032] Second implementation method:

[0033] Figure 3 , Figure 7 A floating hydrogen production platform for marine applications is shown. The output end of the hydraulic telescopic drive mechanism 6 is provided with a universal joint mechanism 11. The universal joint mechanism 11 includes a columnar connecting housing 12, which is located at the output end of the hydraulic telescopic drive mechanism 6. A ball joint universal connector 13 is movably connected to the upper end of the columnar connecting housing 12. The ball joint universal connector 13 is in contact with the lower part of the annular dynamic counterweight cover 7. The ball joint universal connector 13 is movably connected inside the columnar connecting housing 12, which can flexibly adapt to the angle changes of the annular dynamic counterweight cover 7, ensuring a stable and reliable connection between the hydraulic telescopic drive mechanism 6 and the annular dynamic counterweight cover 7.

[0034] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
