Description

Technical Field

[0001] The invention relates to the technical field of floating structures on water, in particular to a wind and wave resistant offshore experimental floating platform. Background Art

[0002] Metal organic frameworks (MOFs) and high surface area nanomaterials are used to extract uranium from seawater. These materials have adjustable pore sizes and functionalized surfaces, which can improve the selectivity and adsorption capacity of uranium ions. In addition, biomass materials, such as seaweed and chitosan, have also been studied for uranium adsorption, which is both environmentally friendly and efficient.

[0003] Announcement No. CN216762098U discloses a self-sustaining anti-wave floating body with diversion and resistance for floating platforms or water platforms, including a diversion and resistance shell, a water-repellent lightweight material, a rib fastener, a central axis and a low-resistance wear-resistant disc. The diversion and resistance shell is connected to the central axis arranged at the center of the diversion and resistance shell through the rib fastener, forming an anti-impact structure and an anti-wave diversion and resistance body that automatically turns around the central axis to adjust the diversion and diversion angle; the low-resistance wear-resistant disc is arranged at both ends of the diversion and resistance shell and connected to the central axis; the water-repellent lightweight material is bonded and fixed in the diversion and resistance shell. The impact and vibration of ocean waves and strong airflow on the floating body are weakened, thereby greatly weakening the impact and vibration on the floating platform or water working platform; the floating body is durable, safe and reliable; it is easy to expand quickly and is the basic unit of a stable working platform on the water or at sea; it is conducive to the construction of an ocean platform or working platform.

[0004] The main factors affecting the stability of the floating platform are the environmental loads in the ocean. Among them, waves are the most complex factor, which can cause six-degree-of-freedom motion including heave, pitch, roll, yaw, longitudinal displacement and lateral displacement. The ocean current will exert continuous force on the floating platform, affecting its position and direction, especially in severe weather conditions, which will have a huge impact on its structure and positioning.

[0005] The floating platform is set to be circular and the influence of environmental load on the floating platform is reduced by using a diversion shell: First, the role of the circular floating platform is limited. When the environmental load impacts the circular floating platform, no matter how the impact direction changes, the stability of the floating platform under the same environmental load is the same. Although it can resist impact in any direction, the resistance effect is general. The second is to divert seawater through a diversion shell. Most diversion shells are arc-shaped. When the arc surface is directly impacted by environmental loads, the impact resistance of the floating platform deteriorates, resulting in the diversion shell having good impact resistance only at specific angles. Summary of the invention

[0006] One of the purposes of the present invention is to provide a wind and wave resistant offshore experimental floating platform, which can protect the floating platform by unloading force under the impact of waves and currents.

[0010] In one or more embodiments of the present invention, the telescopic member consists of a cavity with a cavity configured inside and a telescopic rod located inside the cavity and capable of sliding relative to the cavity. The telescopic rod contacts the inner wall of the cavity, and the ball head rod changes the medium pressure inside the cavity by pulling the telescopic rod.

[0011] In one or more embodiments of the present invention, the joint component is arranged on the outside of the base component and the guardrail component, and the joint component includes: The mounting head is fixed to the outside of the bottom plate component, a rotatable connecting rod is sleeved on the outside of the mounting head, a connecting head is arranged at one end of the connecting rod away from the mounting head, the connecting head can rotate relative to the connecting rod, and a connecting end is arranged between the connecting heads and can be extended to change the length of the connecting head extending to the outside; The sleeve rod is sleeved on the connecting rod and the outer side of the guardrail component. The sleeve rod is telescopically arranged at both ends. Magnets are arranged inside the sleeve rod to support the two ends of the sleeve rod.

[0012] In one or more embodiments of the present invention, the connection end includes: The sleeve head, the connector extends to the interior of the sleeve head, the sleeve head is provided with a first magnetic ring and a second magnetic ring having the same number as the connectors in the joint component, the first magnetic ring is fixed inside the sleeve head, the second magnetic ring is installed outside the connector, and the first magnetic ring and the second magnetic ring are magnetically attracted; The constant pressure chamber is composed of a connector and a sleeve, and the first magnetic ring and the second magnetic ring are both located inside the constant pressure chamber.

[0013] In one or more embodiments of the present invention, the connection plate comprises: The disc is located at the center of the floating platform. The inner side of the disc is equipped with a guide cavity with the same number of guide rods. The guide rods extend into the guide cavity. The guide cavity is filled with medium and the shape of the floating platform can be changed by adjusting the length of the guide rods extending to the outside of the disc.

[0014] In one or more embodiments of the present invention, a medium tube is arranged inside the guide rod, one end of the medium tube is fixed inside the guide rod, the other end of the medium tube extends into the inside of the disk body and is connected to the disk body, and the medium tube is arranged in communication with the guide cavity; A push rod is arranged at one end of the medium pipe fixed to the inner side of the guide rod, and one end of the push rod extending to the outside of the medium pipe is spherical and connected to a floating plate, and the floating plate swings to adjust the length of the push rod located outside the medium pipe.

[0015] In one or more embodiments of the present invention, the connection disk further comprises: The sealing frame is fixed at the bottom of the disc body. A flexible sealing ring is arranged inside the sealing frame. The medium pipe extends to the inside of the sealing frame and is connected to the sealing frame. A deformation rod is arranged at one end of the medium pipe extending to the inside of the sealing frame. The deformation rod is connected to change the shape of the flexible sealing ring: A plurality of medium cavities are arranged inside the sealing frame, and the medium cavities are communicated with the flow guide cavity.

[0016] In one or more embodiments of the present invention, a sealing head is disposed outside the flexible sealing ring and connected to the sealing head, the sealing head extends into the medium cavity and contacts the inner wall of the medium cavity, and the number of medium cavities, medium tubes and flow guide cavities corresponds to the number of guide rods; The guide rod is arranged at the bottom of the outer ring structure and the inner ring structure and connected with the outer ring structure and the inner ring structure.

[0017] Through the above technical solution, the present invention has the following beneficial effects: 1. The floating platform is composed of multiple floating platform components connected by joint components, supporting the offset in four directions, forming a semi-rigid and semi-flexible structure. The joint components are combined with telescopic parts and ball head rods, which have multi-degree-of-freedom compensation capabilities. The swing range of the ball head rod in the spherical pit increases with the distance from the center of the floating platform, realizing progressive deformation when the wave hits.

[0018] 2. The guide rod system is the core of the floating platform shape adjustment. The guide rod extends outward from the central connection plate to the outer floating platform, and a medium pipe is set inside to connect with the diversion cavity. When the floating plate is swung by the impact of waves, the medium pipe is pushed to expand and contract through the top rod, changing the length of the guide rod; the medium in the diversion cavity flows under the pressure change, pushing the guide rod to expand and contract. When the wave impact on one side is strengthened, the medium flows in the opposite direction, making the floating platform deformed into an elliptical shape, realizing the diversion and unloading.

[0019] 3. A NdFeB permanent magnet array is arranged inside the sleeve rod, which forms a non-contact support through like-pole repulsion, allowing axial extension and radial deflection. Compared with traditional mechanical connections, magnetic suspension avoids friction loss and is suitable for long-term offshore operations.

[0020] 4. Arranged around the central connecting plate, it serves as an experimental operation platform and a storage area for seawater uranium extraction materials. The inner and outer rings are connected by guide rods to form a buffer space to reduce the transmission of wave energy to the core area. When the floating platform deforms, the double-layer structure adjusts synchronously to both resolve the impact and maintain overall stability, similar to the synergy of the inner and outer rings of deep groove ball bearings to improve the anti-overturning ability.

[0021] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention.

DETAILED DESCRIPTION

[0024] The following will disclose multiple embodiments of the present invention with the accompanying drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not necessary. And if it is possible to implement, the features of different embodiments can be applied interchangeably.

[0025] Unless otherwise defined, all words (including technical and scientific terms) used herein have their usual meanings, which can be understood by those familiar with this field. Furthermore, the definitions of the above words in commonly used dictionaries should be interpreted in the content of this specification as consistent with the meanings of the relevant fields of the present invention. Unless otherwise clearly defined, these words will not be interpreted as idealized or overly formal.

[0026] The following is an explanation of the relationships and terms used in this application: Parallel: The parallelism defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism, which allows for non-absolute parallelism due to factors such as assembly tolerance, design tolerance, and the influence of structural flatness. Small angular errors are allowed. For example, an assembly error range of less than 10 degrees can be understood as a parallel relationship.

[0027] Vertical: The verticality defined in this application is not limited to an absolute vertical intersection relationship (angle of 90 degrees). It allows for non-absolute vertical intersection relationships caused by factors such as assembly tolerance, design tolerance, and influence of structural flatness. It also allows for errors in a small angle range. For example, the assembly error range of 80 to 100 degrees can be understood as a vertical relationship.

[0028] The above explanation does not completely include the relationship definitions given in this application, but only represents part of it.

[0029] The invention provides a wind and wave resistant offshore experimental floating platform for extracting uranium from seawater at sea.

[0030] See also Figure 1-Figure 3 , Fig. 9 as well as Figure 15-18 As shown, in one embodiment, the floating platform includes: The floating platform components 1 play a supporting role. The floating platform components 1 can at least support the joint components 2 offset in four directions of the floating platform components 1. The joint components 2 are arranged between adjacent floating platform components 1 to connect the floating platform components 1. The floating platform component 1 includes a bottom plate component 11 for supporting and a guardrail component 12 installed on the bottom plate component 11 for protecting. Adjacent bottom plate components 11 and adjacent guardrail components 12 are connected by joint components 2. A floating ring 15 for supporting the floating platform to float on the sea surface is arranged at the bottom of the bottom plate component 11. A gap G is formed between the floating ring 15 and the guardrail component 12. The floating platform component 1 at least comprises an outer ring structure 13 and an inner ring structure 14 . The outer ring structure 13 is connected to the inner ring structure 14 , and the connecting plate 31 is located at the bottom of the inner ring.

[0031] In one feasible method, the inner and outer circle design greatly improves the stability of the platform under the waves, making it easier for people to walk and experiment on the platform. Space is formed between the inner and outer circles to facilitate the launching of uranium extraction materials from seawater and the protection of the materials. When the floating platform is deformed, both the inner and outer circles will deform, thereby ensuring that the floating platform can resolve the impact of waves and currents on the floating platform.

[0032] Among them, a gap G is set between the guardrail component 12 and the floating ring. Therefore, when the floating platform is impacted by waves, the local impact on the floating platform will not directly affect the stability of the entire floating platform. Due to the setting of the inner and outer rings of the floating platform, a multi-dimensional energy natural decomposition structure design is adopted, and the impact in any direction can be decomposed to other positions of the floating platform. Due to the setting of the gap G, even if the floating platform is deformed, only local deformation occurs, which improves the strength and stability of the floating platform. When the floating platform component 1 is displaced and swung, the guardrail component 12 moves synchronously with the bottom plate component 11. When standing on the bottom plate component 11, the guardrail component 12 can stabilize pedestrians.

[0033] The main supporting parts of the floating platform are composed of the floating platform components 1, and the joint components 2 that can satisfy the displacement of the floating platform components 1 in multiple directions are used to ensure the stability of the connection between the floating platform components 1 under the action of waves and currents. The floating platform is not a corresponding integral structure and can produce a certain deformation, which ensures the stability of the floating platform components 1 while avoiding an over-rigid state.

[0034] Among them, since the flexible connection between the floating platform components 1 has a certain deformation amount, it has a certain adjustability compared to the integrated floating platform, and the adjustability of the floating platform components 1 can be used to adjust the state of the floating platform according to the state of waves and currents. When the floating platform is in a state of waves and currents of different directions and intensities, it can reduce the impact on the floating platform and ensure the safety of the floating platform.

[0035] See also Figure 1-Figure 4 As shown, in one embodiment, the floating platform further comprises: The connecting member 3 is arranged on the inner side of the floating platform component 1. The connecting member 3 includes a connecting disk 31 set in the middle position of the floating platform and a guide rod 32 extending outward in multiple directions with the connecting disk 31 as the center. The guide rod 32 extends to the outermost side of the floating platform. The guide rod 32 can be retracted and change the angle between the outer floating platform components 1. The outer side of the outer floating platform component 1 is provided with a floating plate 4. The floating plate 4 can be swingably installed on the outer side of the floating platform component 1 and drive the connecting member 3 to change the floating platform component 1.

[0036] In one practicable manner, the retractable setting of the connector 3 is used to change the shape of the floating platform, and the deformable floating platform is used to guide the waves and currents, so that the floating platform can be more stable in the sea water and reduce the impact on the floating platform. Since the changes in waves and currents will be fed back to the connector 3 through the floating plate 4, the connector 3 can change the state of the floating platform according to the state of the waves and currents.

[0037] See also Figure 7-Figure 8 As shown, in one embodiment, the joint component 2 is arranged inside the base component 11 and the guardrail component 12, and the joint component 2 includes: The telescopic member 211 is installed inside the bottom plate member 11 and the guardrail member 12. A spherical pit 212 is arranged at one end of the telescopic member 211 extending outward. The inside of the telescopic member 211 is filled with a medium. The telescopic member 211 is extended and retracted to change the medium pressure. The ball head rod 213 is arranged inside the spherical pit 212. The ball head rod 213 can swing relative to the telescopic end of the telescopic member 211, with the middle of the floating platform as the center. The farther the ball head rod 213 is from the center, the larger the swing range is. The end of the ball head rod 213 away from the telescopic member 211 is configured with a coupling 214 and connected to the coupling 214.

[0038] In one practicable manner, the joint member 2 is arranged inside the bottom plate member 11 and the guardrail member 12, and a telescopic member 211 and a ball head rod 213 are combined to form a design, the core of which is multi-degree-of-freedom compensation and dynamic pressure feedback. The swing range of the ball head rod 213 in the spherical pit 212 follows the principle of "the farther from the center, the greater the swing amplitude", and the progressive deformation during wave impact is achieved through geometric asymmetric design. For example, the maximum swing angle of the ball head rod 213 10 meters away from the center of the floating platform can reach ±25°, while only ±5° fine adjustment is allowed near the center.

[0039] Among them, wave energy is dissipated through three stages: The initial impact is dispersed by the universal joint structure of the ball head rod 213 to the adjacent floating platform member 1; The remaining energy is converted into heat energy through the compression of the medium of the telescopic member 211; Finally, the remaining energy is stored through the elastic deformation of the coupling 214 .

[0040] See also Figure 8 As shown, in one embodiment, the telescopic member 211 is composed of a cavity 2111 with an internally configured cavity and a telescopic rod 2112 located inside the cavity and capable of sliding relative to the cavity 2111. The telescopic rod 2112 contacts the inner wall of the cavity, and the ball head rod 213 changes the medium pressure inside the cavity by pulling the telescopic rod 2112.

[0041] Optionally, the telescopic rod 2112 divides the cavity into two independent chambers. When the telescopic rod 2112 is not subjected to force, the pressure inside the two chambers is the same. When the telescopic rod 2112 is subjected to a pulling force, the volume of the chamber on one side increases and the pressure decreases, while the volume of the chamber on the other side decreases and the pressure increases. When the telescopic rod 2112 is not pulled, due to the different pressures in the two chambers, the telescopic rod 2112 is reset by pressure balance.

[0042] Alternatively, one end of the cavity is open, and the telescopic rod 2112 extends into the opening. In this case, there is only one cavity. When the telescopic rod 2112 is pulled, it can be faster, but when the pulling force of the telescopic rod 2112 is too large, the cavity may shrink.

[0043] In an practicable manner, support members are installed between adjacent bottom plate components 11 , and when the gap between the bottom plate components 11 increases, the telescopic rods 2112 on both sides are in the same state, thereby ensuring the stable connection of the joint component 2 .

[0044] See also Figure 9-14 As shown, in one embodiment, the joint component 2 is arranged outside the base component 11 and the guardrail component 12, and the joint component 2 includes: The mounting head 221 is fixed to the outside of the bottom plate member 11. A rotatable connecting rod 222 is sleeved on the outside of the mounting head 221. A connecting head 223 is arranged at one end of the connecting rod 222 away from the mounting head 221. The connecting head 223 can rotate relative to the connecting rod 222. A connecting end 224 is arranged between the connecting heads 223 and can extend and change the length of the connecting head 223 to the outside. The sleeve rod 225 is sleeved on the connecting rod 222 and the outer side of the guardrail component 12. The sleeve rod 225 is telescopically arranged at both ends. A magnet 226 is arranged inside the sleeve rod 225 to support the two ends of the sleeve rod 225.

[0045] In one feasible method, the joint component 2 is installed on the outside of the base component 11 and the guardrail component 12, and the outer joint adopts a three-degree-of-freedom mechanical structure: the mounting head 221 and the connecting rod 222 form an axial rotation pair, the connecting rod 222 and the connecting head 223 constitute a spherical pair, and the magnetic suspension system of the sleeve rod 225 provides axial telescopic compensation.

[0046] The sleeve rod 225 has a neodymium iron boron permanent magnet array inside, which forms a repulsive force field by arranging the same poles relative to each other, so as to buffer the impact and avoid mechanical contact wear.

[0047] See also Figure 13-14 As shown, in one embodiment, the connection end 224 includes: The sleeve 2241, the connector 223 extends to the inside of the sleeve 2241, and the sleeve 2241 is provided with a first magnetic ring 2242 and a second magnetic ring 2243 which are the same in number as the connector 223 in the joint component 2, the first magnetic ring 2242 is fixed inside the sleeve 2241, and the second magnetic ring 2243 is installed outside the connector 223, and the first magnetic ring 2242 and the second magnetic ring 2243 are magnetically attracted; The constant pressure chamber 2244 is composed of a connector 223 and a sleeve 2241 . The first magnetic ring 2242 and the second magnetic ring 2243 are both located inside the constant pressure chamber 2244 .

[0048] In one feasible manner, a certain displacement is provided between adjacent bottom plate components 11 through the magnetic connection of the first magnetic ring 2242 and the second magnetic ring 2243, and the volume of the constant pressure chamber 2244 increases when the connector 223 is pulled outward, so that the chamber can be more stable when the first magnetic ring 2242 and the second magnetic ring 2243 are reset.

[0049] See also Figure 4-Figure 6 As shown, in one embodiment, the connection plate 31 includes: The disk body 311 is located at the center of the floating platform. The inner side of the disk body 311 is configured with guide cavities 312 with the same number as the guide rods 32. The guide rods 32 extend into the guide cavities 312. The guide cavities 312 are filled with medium and the shape of the floating platform can be changed by adjusting the length of the guide rods 32 extending to the outside of the disk body 311.

[0050] In one feasible method, since the disk body 311 is arranged at the center position of the floating platform, and the guide rod 32 extends outward from the center position and is connected to the bottom plate component 11, after the length of the guide rod 32 located outside the disk body 311 is changed, the bottom plate component 11 is pulled to move, causing the floating platform to deform, and unload force according to the state of waves and currents, thereby reducing the impact of waves and currents on the floating platform.

[0051] See also Figure 5-Figure 6 As shown, in one embodiment, a medium tube 33 is disposed inside the guide rod 32, one end of the medium tube 33 is fixed inside the guide rod 32, and the other end of the medium tube 33 extends to the inside of the disk body 311 and is connected to the disk body 311, and the medium tube 33 is connected to the guide cavity 312; A push rod 34 is provided at one end of the medium tube 33 fixed to the inner side of the guide rod 32 . One end of the push rod 34 extending to the outside of the medium tube 33 is spherical and connected to the floating plate 4 . The floating plate 4 swings to adjust the length of the push rod 34 outside the medium tube 33 .

[0052] In one feasible method, the guide rod 32, the bottom plate member 11, and the floating plate 4 move synchronously, and the medium tube 33 is fixed to the inner side of the floating plate 4. When in use, the position of the guide rod 32 can be changed, and the waves and the current control the guide rod 32 at the other end to be pushed outward through the floating plate 4, so that the floating platform forms an ellipse along the flow direction of the waves and the current, which can better guide the flow and reduce the impact.

[0053] See also Figure 5-Figure 6 As shown, in one embodiment, the connection disk 31 further includes: The sealing frame 313 is fixed to the bottom of the disk 311. The sealing frame 313 is provided with a flexible sealing ring 314. The medium tube 33 extends to the inside of the sealing frame 313 and is connected to the sealing frame 313. The end of the medium tube 33 extending to the inside of the sealing frame 313 is provided with a deformation rod 315. The deformation rod 315 is connected to change the shape of the flexible sealing ring 314: A plurality of medium cavities 316 are disposed inside the sealing frame 313 , and the medium cavities 316 are connected to the flow guiding cavity 312 .

[0054] In one practicable manner, the medium pipe 33 is arranged in a tee to change the state of the flexible sealing ring 314, so that the sealing ring is deformed, and the sealing ring seals the medium cavity 316. After the sealing ring is deformed, the volume of the medium cavity 316 changes: When the volume of the medium cavity 316 increases, the medium in the flow guiding cavity 312 enters the medium cavity 316, so that the guide rod 32 retracts, and the distance between the outer edge and the center position of the guide rod 32 is reduced; When the volume of the medium cavity 316 is reduced, the medium in the medium cavity 316 enters the flow guide cavity 312, so that the guide rod 32 is extended, and the distance between the outer edge and the center position of the guide rod 32 is increased; By adjusting the length of the guide rod 32, the floating platform is deformed into an elliptical shape for flow diversion.

[0055] See also Figure 1-Figure 6 As shown, in one embodiment, a sealing head 317 is disposed outside the flexible sealing ring 314 and connected to the sealing head 317, the sealing head 317 extends into the medium cavity 316 and contacts the inner wall of the medium cavity 316, and the number of the medium cavity 316, the medium tube 33 and the guide cavity 312 all corresponds to the number of the guide rods 32; The guide rod 32 is disposed at the bottom of the outer ring structure 13 and the inner ring structure 14 and connected to the outer ring structure 13 and the inner ring structure 14 .

[0056] In one practicable manner, the floating platform is deformed by the impact of waves and currents on the floating board 4, and the double-layer circular structure greatly improves the structural rigidity and strength of the platform itself, and greatly improves the ability to resist wind and waves. The connections between the floating platform components 1 are all connected by joint components 2, which are both connected and can move freely. The impact of waves in different directions and the ups and downs are only locally stressed, and the floating platform will not be twisted or damaged by the force due to large waves and its own weight.

[0057] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages: Mechanical dispersion: The universal joint structure of the ball head rod 213 disperses the initial impact to the adjacent floating platform component 1; Medium compression: The interior of the telescopic member 211 is filled with a compressible medium such as hydraulic oil or gas to convert the remaining energy into heat energy; Elastic energy storage: The coupling 214 stores residual energy through elastic deformation to avoid structural overload.

[0058] Three-degree-of-freedom compensation: The NdFeB permanent magnet array is arranged inside the sleeve 225, which forms a non-contact support through the repulsion of the same poles, allowing axial extension and radial deflection. The magnetic suspension system can buffer up to 90% of the high-frequency vibration energy.

[0059] Wear-free operation: Compared with traditional mechanical connections, magnetic levitation avoids friction losses and is suitable for long-term offshore operations.

[0060] The design draws on the principles of compensators such as bellows to absorb deformation and the dynamic adaptability of ball joints.

[0061] Although the present invention is disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the attached claims.
