Description

Technical Field

[0001] The present invention relates to the technical field of floating platforms, and more particularly to an automatic submersible floating platform system based on tide level and a working method thereof. Background Art

[0002] Floating platforms are an important part of floating structures on water. However, due to their unique geographical location, coastal areas are often threatened by extreme weather events such as typhoons and hurricanes. The high tides and storm surges brought by these extreme weather events will generate huge wave loads, posing severe challenges to the floating platform structure.

[0003] Traditional protective measures, such as building breakwaters and setting up wave walls, can reduce the impact of waves on floating platforms to a certain extent, but these methods often require huge economic costs, cannot adapt to different ocean conditions, and their protective effects may not be ideal when facing extreme weather.

[0004] In extreme cases, these protective measures may not be able to fully resist the strong wave impact, resulting in damage to the floating platform structure; at the same time, ocean waves behave differently in deep and shallow water environments, affecting the design and function of the offshore floating platform structure; in deep water, water particles move in a circular orbit, and their intensity decays exponentially with depth; while in shallow water, water particles move in an elliptical orbit and become flattened when close to the seabed; these differences significantly affect wave transfer and transformation, sediment flow and the load on marine structures; for this reason, an automatic submersible floating platform system based on tide level and its working method are proposed to improve the existing problems. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a tidal-based automatic submersible floating platform system and a working method thereof which has strong corrosion resistance and is adaptable to different marine conditions.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic submersible floating platform system based on tide level, comprising a floating component and a limiting component; wherein the floating component comprises a floating platform, an inflow check valve arranged on the top of the floating platform, a first normally closed solenoid valve arranged at the input end of the inflow check valve, and a second normally closed solenoid valve arranged on one side of the inflow check valve; the limiting component is symmetrically arranged at both ends of the floating platform, comprising a fixed pile, a pile stopper sleeved on the fixed pile, and a base block arranged at one end of the fixed pile away from the pile stopper; a cavity is opened in the floating platform, the output end of the inflow check valve can pass through the top of the floating platform and be connected to the cavity, and the input end of the second normally closed solenoid valve can pass through the top of the floating platform and be connected to the cavity.

[0007] The present invention is further configured as follows: a compressed air nozzle is also provided on one side of the inflow check valve and the second normally closed solenoid valve, the input end of the compressed air nozzle is connected to an air compressor, and the output end of the compressed air nozzle can penetrate the top of the floating platform and communicate with the cavity.

[0008] The present invention is further configured as follows: the air compressor also includes a compressed air tank, and the compressed air tank is located on the deck of the floating platform.

[0009] The present invention is further configured as follows: an outflow check valve is also arranged on the deck of the floating platform, and the input end of the outflow check valve can extend to the bottom of the cavity of the floating platform; a liquid level sensor is also arranged on the top of the floating platform, and the detection end of the liquid level sensor is located in the cavity.

[0010] The present invention is further configured as follows: a through hole is symmetrically provided on the top of the floating platform, and a through tube is arranged in the through hole; one end of the through tube is cylindrical, and the other end is truncated cone-shaped, the cylindrical end of the through tube can be connected to the top of the floating platform, and the truncated cone end can be connected to the bottom of the floating platform, and the floating platform can be mounted on a fixed pile through the through tube.

[0011] The present invention is further configured as follows: adjustment holes are evenly opened on the side walls in the vertical direction of the fixed pile, and latches are arranged in the adjustment holes; pile blocking holes are opened on the side walls of the pile blocking block, and the pile blocking holes can be aligned with the adjustment holes, and one end of the latch can pass through the pile blocking holes and the adjustment holes, and simultaneously penetrate the pile blocking block and the side walls of the fixed pile.

[0012] The present invention is further configured as follows: one end of the base block is truncated cone-shaped, and the other end is cylindrical; the truncated cone-shaped end of the through-tube can be plugged into the truncated cone-shaped end of the base block.

[0013] The present invention is further configured as follows: the floating platform is in the form of a rectangular parallelepiped and is made of carbon steel.

[0014] The present invention is further configured such that: the surface of the floating platform is covered with an anti-corrosion coating.

[0015] The working method of the automatic submersible floating platform based on tide level, using the automatic submersible floating platform system based on tide level as described above, comprises the following steps: S1, floating platform sinks; S11. Under normal tide conditions, the floating platform can stably float on the water surface and move vertically freely with the natural rise and fall of the tide; S12. After receiving a hurricane forecast, the operator needs to take action in advance and start the emergency procedure at least two days before the storm is expected to arrive, opening the first normally closed solenoid valve and the second normally closed solenoid valve; S13. As the tide level continues to rise, the tide level will drive the floating platform to rise synchronously until the top of the floating platform hits the pile block, and the floating platform will stop moving; S14. When the rising liquid level covers the top of the floating platform, the floating platform will be slowly submerged, and water will flow into the floating platform through the first normally closed solenoid valve installed on the top of the floating platform and then through the inflow check valve; S15. When the total weight of the water inside the floating platform and the deadweight of the floating platform exceed its displacement, the floating platform begins to sink; eventually, the floating platform sinks to a height that contacts the base block, maintaining a certain distance from the seabed to avoid direct contact; at this point, the floating platform is completely fixed on top of the base block, not only maintaining a stationary state, but also effectively preventing any horizontal movement of the floating platform; S2, the floating platform resurfaces; S21. After the extreme high tide and big waves subside, the first normally closed solenoid valve and the second normally closed solenoid valve are closed. At this time, the air is compressed by the air compressor to become high-pressure compressed air, and the high-pressure compressed air is then injected into the cavity through the compressed air nozzle equipped on the floating platform; S22. At the same time, the water in the cavity can only be discharged through the outflow check valve. This drainage process ensures that the floating platform can resurface as the water is discharged; S23. As the water in the cavity of the floating platform is gradually discharged, once the remaining water plus the weight of the floating platform becomes lighter than the total displacement of the floating platform, the floating platform will gradually float up.

[0016] In summary, the present application includes at least one of the following beneficial technical effects: (1) Through the design of floating components, as a key facility on the floating dock, its design cleverly combines flexibility and stability and can adapt to different marine conditions; the floating platform is made of carbon steel and its surface is covered with an anti-corrosion coating to meet the requirements of long-term marine environment.

[0017] (2) Through the cooperation of the limit assembly, the staff is allowed to adjust the maximum rising height of the floating assembly according to the actual situation, thereby achieving highly precise control of the floating assembly; this design not only improves the adaptability of the system, but also enhances the flexibility of operation under extreme weather conditions.

[0018] (3) Through the coordination of the floating assembly and the limiting assembly, before the arrival of storm surges or huge waves, the floating assembly can strategically sink to a safe position according to pre-set procedures or the operator's instructions, thereby avoiding direct exposure to destructive wave forces and surfacing when conditions improve; the system uses natural tidal changes and compressed air for diving and surfacing, providing safe and efficient protection for offshore floating platform structures in deepwater environments.

[0026] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention.

[0027] Unless otherwise defined, the technical or scientific terms used in the present invention shall have the usual meanings understood by persons with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" and the like mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0028] See also Figure 1-Figure 6 , the present invention provides the following technical solutions: Example 1, see Figure 1-Figure 6 The automatic submersible floating platform system based on tide level includes a floating component 1 and a limiting component 2; among them, the floating component 1 is a key facility on the floating dock, and its design cleverly combines flexibility and stability, and is a basic component of floating buildings on water; at the same time, if it is a basic component of floating buildings on water, it must also ensure that it dives during high tide and extreme weather to reduce the impact of wave force, and surfaces when conditions improve.

[0029] The design of the limit component 2 reflects a deep understanding of environmental changes and a high regard for equipment safety; it allows staff to adjust the maximum rising height of the floating component 1 according to actual conditions, thereby achieving highly precise control of the floating component 1; this design not only improves the adaptability of the system, but also enhances the flexibility of operation under extreme weather conditions.

[0030] When facing the challenges of extreme weather, the synergy between the floating component 1 and the limiting component 2 is particularly important; before the arrival of storm surges or huge waves, the floating component 1 can strategically sink to a safe position according to pre-set procedures or the operator's instructions, thereby preventing the floating platform 11 from being directly exposed to destructive wave forces. This intelligent response mechanism and precise control method significantly reduce the risk of damage to the floating platform 11; as the high tide recedes, the floating component 1 surfaces again; this adaptive lifting mechanism protects the floating platform 11 from damage.

[0031] In addition, the design of this floating platform 11 also reflects considerations for environmental impact, avoiding the damage that traditional breakwaters and wave walls may cause to the marine ecosystem during construction and maintenance; by minimizing interference with the natural environment, floating platform 11 not only improves its own reliability and safety, but also contributes to marine protection.

[0032] See also Figure 1-Figure 4Specifically, the floating assembly 1 includes a floating platform 11, an inflow check valve 12 arranged on the top of the floating platform 11, a first normally closed solenoid valve 13 arranged at the input end of the inflow check valve 12, and a second normally closed solenoid valve 14 arranged on one side of the inflow check valve 12.

[0033] Among them, under normal tide conditions, the floating platform 11 can float stably on the water surface and move vertically freely with the natural rise and fall of the tide; this design gives the floating platform 11 extremely high adaptability, allowing it to operate smoothly and not be affected by daily sea level fluctuations.

[0034] However, in the face of impending extreme weather events, such as hurricanes, the response strategy of the floating platform 11 is also particularly important; after receiving a hurricane forecast, the operator needs to take action in advance, at least two days before the storm is expected to arrive, to initiate the emergency procedure and open the first normally closed solenoid valve 13 and the second normally closed solenoid valve 14. The opening of these two solenoid valves will trigger the diving mechanism of the floating platform 11, causing it to dive to a safe depth below the water surface.

[0035] This proactive approach of advance preparation is crucial as it not only provides Floating Platform 11 with enough time to adjust to a safe state to withstand the high waves and strong winds brought by the upcoming storm, but also ensures the integrity of the entire Floating Platform 11 structure; through this preventative measure, Floating Platform 11 is able to minimize potential damage caused by extreme weather.

[0036] See also Figure 5-Figure 6 Specifically, the limiting assembly 2 is symmetrically arranged at both ends of the floating platform 11, and includes a fixed pile 21, a pile stopper 22 sleeved on the fixed pile 21, and a base block 23 arranged at one end of the fixed pile 21 away from the pile stopper 22.

[0037] Among them, the operator can adjust the vertical height of the pile block 22 on the fixed pile 21 by finely adjusting the pile block 22. This design cleverly gives the floating platform 11 flexibility in the vertical direction; in this way, the operator can accurately set a suitable rising height limit based on actual sea conditions and tidal forecasts, ensuring that the floating platform 11 can adapt to environmental changes when facing different liquid level changes, thereby optimizing its operating efficiency and safety.

[0038] The vertical displacement adjustment mechanism of the pile block 22 not only improves the adaptability of the floating platform 11 to sea level fluctuations, but also enhances its survivability under extreme weather conditions; this adjustment function enables the platform to reduce the direct impact of waves by diving to the seabed before the arrival of storm surges or huge waves, and to rise to resume normal working conditions during calm periods.

[0039] The design of the foundation block 23 is also crucial. It not only prevents the floating platform 11 from moving horizontally and ensures the stability of the platform in wind and waves, but also improves the bearing capacity and overall stiffness of the entire pile foundation through its structural design. The stability and strength of the foundation block 23 are crucial to protecting the floating platform 11 from current impact and wave impact.

[0040] It should be noted that when a hurricane is forecast, the pile stopper 22 is fixed to the fixed pile 21, and the height of the pile stopper 22 is the highest astronomical tide level or any height lower than HAT.

[0041] Through the cooperation between the floating assembly 1 and the limiting assembly 2, as the tide level continues to rise, the tide level will drive the floating platform 11 to move synchronously until the top of the floating platform 11 hits the pile stopper 22, the floating platform 11 stops moving, and the tide continues to rise, thereby effectively preventing the floating platform 11 from continuing to rise; when the rising liquid level covers the top of the floating platform 11, the floating platform 11 will slowly be submerged, and the water will enter the floating platform 11 through the inflow check valve 12 installed on the top of the floating platform 11; when the total weight of the water inside the floating platform 11 and the deadweight of the floating platform 11 exceed its displacement, the floating platform 11 begins to sink; finally, the floating platform 11 will sink to the height of contact with the base block 23, keep a certain distance from the seabed, and avoid direct contact. At this time, the floating platform 11 is completely fixed on the top of the base block 23, not only maintaining a static state, but also effectively preventing any horizontal movement of the floating platform 11.

[0042] When a hurricane strikes the original position of the floating platform 11, large waves will pass over the submerged floating platform 11, which will experience little dynamic force from the waves; this submerged position ensures that the platform remains stable and protected from the destructive effects of the hurricane.

[0043] See also Figure 1-Figure 2 Furthermore, a cavity 111 is opened in the floating platform 11, and the output end of the one-way valve 12 can pass through the top of the floating platform 11 and be connected to the cavity 111. The input end of the second normally closed solenoid valve 14 can pass through the top of the floating platform 11 and be connected to the cavity 111.

[0044] Among them, after receiving a hurricane forecast, the operator needs to take action in advance and start the emergency procedure at least two days before the storm is expected to arrive, and open the first normally closed solenoid valve 13 and the second normally closed solenoid valve 14; the second normally closed solenoid valve 14 is a normally closed solenoid valve for exhaust, which can gradually discharge the gas in the cavity 111 into the atmosphere.

[0045] When the rising liquid level covers the top of the floating platform 11 , the floating platform 11 will be slowly submerged, and the water will flow into the cavity 111 through the first normally closed solenoid valve 13 installed on the top of the floating platform 11 and then through the one-way valve 12 .

[0046] Example 2, see Figure 3-Figure 4 Furthermore, a compressed air nozzle 15 is provided on one side of the one-way valve 12 and the second normally closed solenoid valve 14. The input end of the compressed air nozzle 15 is connected to an air compressor 16. The output end of the compressed air nozzle 15 can penetrate the top of the floating platform 11 and communicate with the cavity 111.

[0047] It should be noted that the air compressor 16 also includes a compressed air tank, which is located on the deck of the floating platform 11 and is triggered to open and close the second normally closed solenoid valve 14 by an underwater remote control signal.

[0048] Among them, after the extreme high tide and big waves subside, the first normally closed solenoid valve 13 and the second normally closed solenoid valve 14 are closed to maintain the sealing of the cavity 111. At this time, the air is compressed by the air compressor 16 to become high-pressure compressed air, and the high-pressure compressed air is then injected into the cavity 111 through the compressed air nozzle 15 equipped on the floating platform 11; this pressurized air replaces the cavity 111 previously filled with water, preparing for the floating platform 11 to re-float.

[0049] See also Figure 3-Figure 4 Furthermore, an outflow check valve 17 is provided on the deck of the floating platform 11 , and an input end of the outflow check valve 17 can extend to the bottom of the cavity 111 of the floating platform 11 .

[0050] When high-pressure compressed air is injected into the cavity 111 through the compressed air nozzle 15, since the first normally closed solenoid valve 13 and the second normally closed solenoid valve 14 are already closed, the water in the cavity 111 can only be discharged through the outflow one-way valve 17. This drainage process ensures that the floating platform 11 can resurface as the water is discharged.

[0051] As the water in the cavity 111 of the floating platform 11 is gradually drained, once the remaining water plus the weight of the floating platform 11 becomes lighter than the total displacement of the floating platform 11, the floating platform 11 will gradually float up; this gradual re-surfacing ensures that the floating platform 11 returns to its original floating position safely and effectively.

[0052] See also Figure 3-Figure 4 Furthermore, a liquid level sensor 18 is provided on the top of the floating platform 11 , and a detection end of the liquid level sensor 18 is located in the cavity 111 .

[0053] The function of the liquid level sensor 18 is to accurately grasp the liquid level information in the cavity 111 .

[0054] Embodiment 3: Through the technical solutions in Embodiment 1 and Embodiment 2, although existing protective measures such as building breakwaters and setting wave-blocking walls are solved, although the impact of waves on the floating platform can be reduced to a certain extent, these methods often require huge economic costs, and in the face of extreme weather, their protective effects may not be ideal; however, the problem of how the floating platform can be stably in the water and not be impacted by the water in this technical solution is still not solved; for this reason, the following solution is proposed: See also Figure 5-Figure 6 Furthermore, a through hole 112 is symmetrically provided on the top of the floating platform 11 , and a through tube 113 is provided in the through hole 112 .

[0055] One end of the through-tube 113 is cylindrical, and the other end is truncated cone-shaped. The cylindrical end of the through-tube 113 can be connected to the top of the floating platform 11, and the truncated cone end can be connected to the bottom of the floating platform 11. The floating platform 11 can be mounted on the fixed pile 21 through the through-tube 113.

[0056] One end of the base block 23 is in a truncated cone shape, and the other end is in a cylindrical shape. The truncated cone-shaped end of the through tube 113 can be plugged into the truncated cone-shaped end of the base block 23 .

[0057] When the total weight of the water in the cavity 111 and the deadweight of the floating platform 11 exceed its displacement, the floating platform 11 begins to sink; eventually, the floating platform 11 sinks to a height in contact with the base block 23, maintaining a certain distance from the seabed to avoid direct contact.

[0058] During this process, since one end of the through-tube 113 is cylindrical and the other end is truncated cone, and one end of the base block 23 is truncated cone and the other end is cylindrical, the truncated cone end of the through-tube 113 can be plugged into the truncated cone end of the base block 23. Therefore, the floating platform 11 can be plugged into the base block 23 through the mutual cooperation of the truncated cone end of the through-tube 113 and the truncated cone end of the base block 23. At this time, the floating platform 11 is completely fixed on the top of the base block 23, which not only maintains a static state, but also effectively prevents any horizontal movement of the floating platform 11.

[0059] See also Figure 5-Figure 6 Furthermore, adjustment holes 24 are evenly formed on the side walls of the fixing pile 21 in the vertical direction, and latches 25 are arranged in the adjustment holes 24 .

[0060] A pile blocking hole 221 is provided on the side wall of the pile blocking block 22 , and the pile blocking hole 221 can be aligned with the adjustment hole 24 . One end of the latch 25 can pass through the pile blocking hole 221 and the adjustment hole 24 , and simultaneously penetrate the pile blocking block 22 and the side wall of the fixed pile 21 .

[0061] Among them, the pile stopper 22 is sleeved on the fixed pile 21 and can be moved up and down on the fixed pile 21 at will. When it moves to the height specified by the staff, the adjustment hole 24, the latch 25 and the pile stopper hole 221 can cooperate with each other, and the latch 25 can be simultaneously inserted into the adjustment hole 24 and the pile stopper hole 221, so that the fixed pile 21 and the pile stopper 22 are fixed, thereby achieving the purpose of limiting the pile stopper 22, which can effectively prevent the floating platform 11 from moving along the fixed pile 21 beyond the preset height.

[0062] See also Figure 1-Figure 6 Furthermore, the floating platform 11 is in the shape of a rectangular parallelepiped and is made of carbon steel.

[0063] The floating platform 11 is in the shape of a cuboid, which is convenient for modular manufacturing. The small modular floating platform 11 is convenient for production and transportation, and is also convenient for rapid installation on site.

[0064] See also Figure 1-Figure 6 Furthermore, the surface of the floating platform 11 is covered with an anti-corrosion coating to prevent it from being corroded when exposed to the seawater environment for a long time, so as to resist the influence of corrosion and extreme weather.

[0065] The anti-corrosion coating is treated by sandblasting with metal particles, spraying primer and topcoat for anti-corrosion and anti-fouling, thereby increasing the service life of the floating platform 11.

[0066] Embodiment 4, a working method of an automatic submersible floating platform based on tide level, using the automatic submersible floating platform system based on tide level as described above, comprises the following steps: S1. The floating platform 11 sinks.

[0067] S11. Under normal tide conditions, the floating platform 11 can stably float on the water surface and freely move vertically with the natural rise and fall of the tide.

[0068] S12. After receiving a hurricane forecast, the operator needs to take action in advance, start the emergency procedure at least two days before the storm is expected to arrive, and open the first normally closed solenoid valve 13 and the second normally closed solenoid valve 14.

[0069] S13. As the tide level continues to rise, the tide level will drive the floating platform to rise synchronously until the top of the floating platform hits the pile block, and the floating platform will stop moving.

[0070] S14. When the rising liquid level covers the top of the floating platform 11, the floating platform 11 will be slowly submerged, and water will flow into the floating platform 11 through the first normally closed solenoid valve 13 installed on the top of the floating platform 11 and then through the one-way valve 12.

[0071] S15. When the total weight of the water inside the floating platform 11 and the weight of the floating platform 11 exceed its displacement, the floating platform 11 begins to sink; eventually, the floating platform 11 sinks to a height that contacts the base block 23, maintaining a certain distance from the seabed to avoid direct contact. At this point, the floating platform 11 is completely fixed on the top of the base block 23, not only maintaining a stationary state, but also effectively preventing any horizontal movement of the floating platform 11.

[0072] S2. The floating platform 11 resurfaces.

[0073] S21. After the extreme high tide and big waves subside, the first normally closed solenoid valve 13 and the second normally closed solenoid valve 14 are closed. At this time, the air is compressed by the air compressor 16 to become high-pressure compressed air, and the high-pressure compressed air is then injected into the cavity 111 through the compressed air nozzle 15 equipped on the floating platform 11.

[0074] S22. At the same time, the water in the cavity 111 can only be discharged through the outflow one-way valve 17. This drainage process ensures that the floating platform 11 can resurface as the water is discharged.

[0075] S23. As the water in the cavity 111 of the floating platform 11 is gradually discharged, once the weight of the remaining water plus the floating platform 11 becomes lighter than the total displacement of the floating platform 11, the floating platform 11 will gradually float up.

[0076] In summary, the switching states of the first normally closed solenoid valve 13, the second normally closed solenoid valve 14 and the air compressor 16 at each stage are as follows:

[0077] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

12. The tide-based automatic submersible floating platform system according to claim 11, characterized in that: The surface of the floating platform (11) is covered with an anti-corrosion coating.

13. A method for operating a floating platform automatically submerged based on tide level, using the floating platform automatically submerged based on tide level system as claimed in any one of claims 1 to 12, characterized in that: The following steps are involved: S1, floating platform sinks; S11. Under normal tide conditions, the floating platform can stably float on the water surface and move vertically freely with the natural rise and fall of the tide; S12. After receiving a hurricane forecast, the operator needs to take action in advance and start the emergency procedure at least two days before the storm is expected to arrive, opening the first normally closed solenoid valve and the second normally closed solenoid valve; S13. As the tide level continues to rise, the tide level will drive the floating platform to rise synchronously until the top of the floating platform hits the pile block, and the floating platform will stop moving; S14. When the rising liquid level covers the top of the floating platform, the floating platform will be slowly submerged, and water will flow into the floating platform through the first normally closed solenoid valve installed on the top of the floating platform and then through the inflow check valve; S15. When the total weight of the water inside the floating platform and the deadweight of the floating platform exceed its displacement, the floating platform begins to sink; eventually, the floating platform sinks to a height that contacts the base block, maintaining a certain distance from the seabed to avoid direct contact; at this point, the floating platform is completely fixed on top of the base block, not only maintaining a stationary state, but also effectively preventing any horizontal movement of the floating platform; S2, the floating platform resurfaces; S21. After the extreme high tide and big waves subside, the first normally closed solenoid valve and the second normally closed solenoid valve are closed. At this time, the air is compressed by the air compressor to become high-pressure compressed air, and the high-pressure compressed air is then injected into the cavity through the compressed air nozzle equipped on the floating platform; S22. At the same time, the water in the cavity can only be discharged through the outflow check valve. This drainage process ensures that the floating platform can resurface as the water is discharged; S23. As the water in the cavity of the floating platform is gradually discharged, once the remaining water plus the weight of the floating platform becomes lighter than the total displacement of the floating platform, the floating platform will gradually float up.
