Description

Technical Field

[0001] The utility model relates to the technical field of floating platforms, in particular to a floating platform with a riser structure made of cement-based materials that is easy to clean. Background Art

[0002] In the long history of ocean development, floating platforms, as key infrastructure, have always played an irreplaceable role. It has evolved from a simple offshore operation tool in the early days to a comprehensive facility integrating new energy utilization, marine aquaculture, and leisure and entertainment today, witnessing the continuous deepening of human exploration of the ocean and technological progress. However, over time, the limitations of traditional floating platforms have gradually emerged, especially the problem of marine organism attachment has become increasingly serious.

[0003] There is a wide variety and large quantity of marine organisms. In a suitable environment, they will quickly reproduce and grow on the surface of the floating body of the floating platform. These attachments are like heavy "burdens", increasing the overall weight of the platform, disrupting its carefully designed buoyancy balance, and significantly reducing the stability and load-bearing capacity of the platform. In the face of severe weather such as storms, this may pose a risk of tilting or even capsizing, threatening the safety of the platform. In addition, many marine organisms secrete acidic substances during growth or react with seawater through metabolites, accelerating the corrosion of the platform structure, greatly shortening its service life, and increasing maintenance costs and safety risks. Research shows that in areas with severe marine organism attachment, the corrosion rate can be several times faster than normal.

[0004] Removing the biological attachments on the floating platform is a challenge because the floating body is usually underwater, making the cleaning work complex and laborious. If the platform needs to be towed to the shore for each cleaning, it will not only significantly increase the maintenance cost, but also be more difficult to implement for platforms far from the coast. Therefore, it is particularly important to find effective solutions to address this problem. Summary of the Utility Model

A plurality of through holes 3 are provided on the frame structure 1, and the vertical floating tubes 2 are inserted into the through holes 3, and the vertical floating tubes 2 are fixed by the clamping structure 4 after insertion, and the vertical floating tubes 2 are fitted with the inner wall of the through holes 3. The vertical floating tubes 2 have buoyancy, and the frame structure 1 and the vertical floating tubes 2 float on the water surface under the action of the buoyancy. When cleaning regularly, the vertical floating tubes 2 are taken out of the through holes 3, and the vertical floating tubes 2 are rubbed against the inner wall of the through holes 3 to scrape off the marine organisms attached to the outer wall of the vertical floating tubes 2, so as to achieve the purpose of easy cleaning. When cleaning, the vertical floating tube 2 is repeatedly taken out of the through hole 3 and then inserted again, and this is repeated several times, so that the attachments can be removed through the friction and shearing between the component and the tube wall.

[0030] For details, please refer to the attached Figure 5 , 6, the vertical floating pipe 2 is a pipe body with an open upper end and a closed lower end made of UHPC material, and the frame structure 1 is a frame structure 1 made of UHPC material. Ultra-High Performance Concrete, abbreviated as UHPC (Ultra-High Performance Concrete). UHPC material refers to ultra-high performance concrete material. The vertical floating pipe 2 is a pipe body with an open upper end and a closed lower end made of ultra-high performance concrete material, and the frame structure 1 is a frame structure 1 made of ultra-high performance concrete material. The pipe wall of the vertical floating pipe 2 is thin and it is a thin-walled pipe. Using ultra-high performance concrete as the material can provide sufficient compressive and flexural resistance.

[0031] Specifically, the frame structure 1 includes a surface layer perforated plate 5, a middle layer perforated plate 6, a bottom layer support plate 7 and connecting columns 8. The surface layer perforated plate 5, the middle layer perforated plate 6 and the bottom layer support plate 7 are arranged in sequence from top to bottom, and the surface layer perforated plate 5, the middle layer perforated plate 6 and the bottom layer support plate 7 are connected by a plurality of the connecting columns 8. The surface layer perforated plate 5 and the middle layer perforated plate 6 are provided with the through holes 3, and the through holes 3 of the surface layer perforated plate 5 and the middle layer perforated plate 6 are aligned in the vertical direction. The surface layer perforated plate 5, the middle layer perforated plate 6 and the bottom layer support plate 7 are connected by the connecting columns 8 to form an integral frame structure 1. The surface layer perforated plate 5 and the middle layer perforated plate 6 provide a double-layer hoop for the vertical floating pipe 2, making it unable to move in the horizontal direction. Therefore, the vertical floating pipe 2 is fixed in the horizontal direction by using the surface layer perforated plate 5 and the middle layer perforated plate 6, and is supported from below by the bottom layer support plate 7. The cooperation between the bottom layer support plate 7 and the clamping structure 4 fixes the vertical floating pipe 2 in the vertical direction. In the initial stage of platform construction, the vertical floating pipe 2 is placed into the through hole 3, and the bottom layer support plate 7 supports the vertical floating pipe 2 from below. After the vertical floating pipe 2 is installed in place, the clamping structure 4 is used to fix the vertical floating pipe 2.

[0032] Specifically, please refer to Appendix Figure 2 , 3 and 4, a plurality of the vertical floating pipes 2 are arranged in a staggered joint arrangement and inserted into the through holes 3. The pipes can be arranged in a staggered joint, which is convenient for decomposing the seawater waves.

[0033] Optionally, a soft material layer 9 is provided between the vertical floating pipe 2 and the inner wall of the through hole 3. The soft material layer 9 includes a rubber layer or a foamed PE layer. The foamed PE layer is a material layer made of foamed polyethylene material, that is, a foamed polyethylene layer. During the first installation, the soft material layer 9 can play a role in isolating the vertical floating pipe 2 and the through hole 3.

[0034] Preferably, a floating box 10 is further included. The floating box 10 is arranged in the middle of the frame structure 1, and the vertical floating pipes 2 are located around the floating box 10. A relatively large floating box 10 is arranged in the center of the frame structure 1, which can store instruments, articles, tools, etc.

[0035] Specifically, the pontoon 10 is rigidly connected to the frame structure 1. The pontoon 10 is firmly connected to the frame structure 1, and the pontoon 10 can provide a stable supporting force, and can be used together with the frame structure 1 as a supporting member of the floating platform to improve the stability of the floating platform. Preferably, the height of the pontoon 10 is the same as that of the vertical floating tube 2, and the pontoon 10 shares the support and protection of the frame structure 1 with the vertical floating tube 2.

[0036] Specifically, the surface porous plate 5, the middle porous plate 6, the bottom support plate 7, the connecting column 8 and the pontoon 10 are all structural parts made of UHPC materials, and the surface porous plate 5, the middle porous plate 6, the bottom support plate 7, the connecting column 8 and the pontoon 10 are pre-embedded with steel bars 11. The surface porous plate 5, the middle porous plate 6, the bottom support plate 7, the connecting column 8 and the pontoon 10 are fixedly connected by the pre-embedded steel bars 11, and the connection of the steel bars 11 is sealed by a fiber cement slurry layer 12. The frame structure 1 is composed of the surface porous plate 5, the middle porous plate 6, the bottom support plate 7 and the connecting column 8 in the vertical direction. When splicing, the order from bottom to top is followed to connect the various components involved in the frame structure 1 one by one. The surface porous plate 5, the middle porous plate 6, the bottom support plate 7, the connecting column 8 and the pontoon 10 are pre-embedded with steel bars 11, and the connected parts are welded by the pre-embedded steel bars 11, and then sealed with fiber cement slurry. Preferably, the surface layer porous plate 5 and the middle layer porous plate 6 are connected and reinforced by multiple connecting columns 8 .

[0037] Specifically, the buoyancy box 10 is a box body with an upper end opening and a lower end closed, and a cover 13 is provided at the opening of the buoyancy box 10. Instruments, articles, tools, etc. are taken in and out through the upper opening, and the buoyancy box 10 is covered by the cover 13.

[0038] Specifically, the clamping structure 4 includes a surface plate 14, a cover plate 15 and a locking latch 16. The surface plate 14 is fixed on the frame structure 1. The cover plate 15 is rotatably connected to the surface plate 14. The surface plate 14 is provided with a locking latch 16 for clamping the cover plate 15. Preferably, the surface plate 14 is a steel plate. Each vertical floating tube 2 corresponds to a cover plate 15 that can be opened and closed. The cover plate 15 can rotate around an axis to open and close the through hole 3. After the cover plate 15 closes the through hole 3, the locking latch 16 is used to clamp the top of the cover plate 15 to prevent the cover plate 15 from opening, so that the vertical floating tube 2 can be fixed in the vertical direction. After the cover plate 15 is opened, the vertical floating tube 2 can move in the vertical direction.

[0039] Specifically, a buffer material layer 17 is provided between the cover plate 15 and the vertical floating tube 2 , and the buffer material layer 17 includes a foamed polyethylene layer or a rubber layer, so as to improve the sealing performance of the upper end of the vertical floating tube 2 .

[0040] The structures for generating buoyancy in the utility model are a pontoon 10 and a vertical floating tube 2. Due to the tubular structure of the vertical floating tube 2, an appropriate amount of water can be added to the inside of the vertical floating tube 2 to adjust the buoyancy, and a certain amount of water can be accurately loaded according to the actual needs of the platform stability. Preferably, in the early stage of platform construction, the amount of water required by the vertical floating tube 2 under different working conditions is determined through professional calculations and simulations. For example, when the platform is operating on a calm sea, the amount of water in the vertical floating tube 2 can be appropriately reduced to increase the height of the platform; when encountering severe windy and wavey weather, the amount of water in the vertical floating tube 2 can be increased to move the center of gravity of the platform downward and enhance the platform's ability to resist wind and waves. By flexibly adjusting the weight of the water in the vertical floating tube 2, the precise control of the position of the center of gravity of the platform can be achieved, thereby significantly improving the stability and safety of the platform in different marine environments.

[0041] When it is necessary to clean the vertical floating tube 2 of the utility model, the ship-borne crane or the electric hoist equipped on the platform can be used. Both devices have strong lifting capacity and precise operating performance. During the cleaning process, the operator will uncover the cover plate 15 on the upper part of the platform, and then use the crane or electric hoist to lift and lower the vertical floating tubes 2 one by one. Repeat the operation several times, and strong friction and shearing force will be generated between the surface of the vertical floating tube 2 and the inner wall of the through hole 3. This naturally generated force is like an invisible brush, which can efficiently remove marine organisms attached to the surface of the vertical floating tube 2. The buoyancy box 10 is the main cabin of the platform, which can store instruments, items, tools, etc. When it is necessary to clean the outer surface of the buoyancy box 10 in the center of the platform, a vertical floating tube 2 adjacent to it can be lifted, and the holes at the vertical floating tube 2 will appear. At this time, a high-pressure water gun can be inserted into the hole to clean the surface of the buoyancy box 10; the surface of the buoyancy box 10 can be rinsed from the holes around the buoyancy box 10 one by one until the surface of the buoyancy box 10 is cleaned. Finally, the vertical floating tube 2 is accurately put back to its original position and the cover plate 15 is covered to complete the entire cleaning process.

[0042] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. The protection scope of the utility model should be based on the protection scope of the claims.
