Description

Technical Field

[0001] This invention relates to the field of installation and commissioning technology for jack-up platforms, and more particularly to a seawater cooling system for jack-up platforms. Background Technology

[0002] To ensure the safe operation of jack-up platforms, seawater cooling is required during operation. Specifically, the reaction chamber inside the jack-up platform draws seawater from the ocean to cool the platform. The seawater that has absorbed heat is discharged into a seawater cooling module for further cooling. Once the seawater has cooled completely, it is discharged overboard. Throughout this process, the extraction and discharge of seawater maintain a dynamic balance, ensuring that the weight of the jack-up platform remains constant.

[0003] After the self-elevating platform is completed, a full-range lifting test is required to verify its feasibility and reliability. This involves raising the platform from its lowest point to its highest point and then lowering it back down.

[0004] To improve operational convenience, the entire lifting and lowering test of jack-up platforms is usually conducted at shallow water locations such as docks. This results in the jack-up platform leaving the sea surface during the test. Once the jack-up platform rises to a certain height, the reaction chamber inside the platform can no longer pump seawater. At this point, the seawater temporarily stored in the reaction chamber cannot achieve a dynamic balance between seawater pumping and discharge. This not only fails to meet actual cooling requirements but also alters the weight of the jack-up platform, thus making it impossible to effectively verify the assembly quality of the jack-up platform.

[0005] Therefore, there is an urgent need to invent a seawater cooling system for self-elevating platforms to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a seawater cooling system for a jack-up platform, which utilizes the existing structure of the ship to achieve cyclic cooling of seawater and meet practical needs.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] The seawater cooling system for the self-elevating platform includes:

[0009] The seawater cooling module is a structure owned by the ship and has a cooling requirement.

[0010] The docking module is a ship's own structure. The docking module includes a reaction chamber and a transfer chamber. The seawater in the reaction chamber is used to cool the seawater cooling module, and the seawater in the transfer chamber is used to neutralize the heat of the seawater in the reaction chamber.

[0011] A first connecting pipe is configured to connect the output end of the seawater cooling module to the input end of the reaction chamber and the output end of the allocation chamber, respectively. The first connecting pipe is capable of controlling the connection and disconnection between any two of the seawater cooling module, the reaction chamber, and the allocation chamber.

[0012] The second connecting pipe, which is part of the ship's own structure, is configured to connect the output end of the reaction chamber to the input end of the seawater cooling module.

[0013] As an optional solution, the first connecting pipe includes:

[0014] The first connecting main pipeline is connected to the output end of the seawater cooling module, and the first connecting main pipeline can control its own unblocking and blocking.

[0015] A first connecting branch pipe, which is connected to both the first connecting main pipe and the reaction chamber, is capable of controlling its own flow and blockage; and

[0016] The second connecting branch pipe is connected to the first connecting main pipe and the allocation compartment respectively, and the second connecting branch pipe can control its own unblocking and blocking.

[0017] As an option, the first connecting main pipeline has a first main pipeline control valve, which can be configured to unblock or block the first connecting main pipeline.

[0018] And / or, the first connecting branch has a first branch control valve, which is configured to unblock or block the first connecting branch.

[0019] As an optional feature, the allocation compartment includes at least one storage compartment, and the second connecting branch pipeline includes at least one branch pipeline. Each branch pipeline connects one of the storage compartments and the first connecting main pipeline. Each branch pipeline has a branch control valve, and each branch control valve is configured to unblock or block the corresponding branch pipeline.

[0020] As an optional solution, the seawater cooling system of the self-elevating platform has at least two sets of docking modules. Each set of docking modules includes a set of reaction chambers and a set of transfer chambers. The first connecting pipeline includes at least two first connecting branch pipelines and at least two second connecting branch pipelines. Each first connecting branch pipeline connects to a set of reaction chambers and the first connecting main pipeline, and each second connecting branch pipeline connects to a set of transfer chambers and the first connecting main pipeline.

[0021] As an optional solution, the seawater cooling module has an overboard discharge pipeline, the two ends of which are respectively connected to the output end of the seawater cooling module and the overboard. The overboard discharge pipeline has a seawater discharge control valve and an overboard discharge control valve arranged in sequence. Both the seawater discharge control valve and the overboard discharge control valve can control the unblocking and blocking of the overboard discharge pipeline.

[0022] The seawater discharge control valve is located on the side of the outboard discharge control valve near the output end of the seawater cooling module. The outboard discharge pipeline includes a first part located between the seawater discharge control valve and the output end of the seawater cooling module, a second part located between the seawater discharge control valve and the outboard discharge control valve, and a third part located between the outboard discharge control valve and the outboard. The first connecting pipeline is connected to the second part.

[0023] As an optional solution, the seawater cooling module has a drive pump. When the reaction chamber and the allocation chamber are sealed off from each other, the drive pump can drive the seawater in the reaction chamber to flow sequentially through the second connecting pipe, the seawater cooling module and the first connecting pipe before flowing into the allocation chamber.

[0024] With the reaction chamber and the transfer chamber interconnected, the seawater in the transfer chamber flows to the reaction chamber via the first connecting pipe using atmospheric pressure.

[0025] As an optional solution, when no seawater flows into the allocation compartment, the volume of the seawater in the allocation compartment is not less than one-quarter and not more than one-half of the volume of the allocation compartment itself.

[0026] As an optional solution, the seawater cooling system of the self-elevating platform also includes:

[0027] A temporary storage tank is provided for temporarily storing the seawater discharged from the reaction chamber. The second connecting pipe includes a first connecting section and a second connecting section. The first connecting section is used to connect the output end of the reaction chamber with the input end of the temporary storage tank, and the second connecting section is used to connect the output end of the temporary storage tank with the input end of the seawater cooling module.

[0028] As an optional solution, the first connecting pipe has a first end, a second end, and a third end. The first end is connected to the output end of the seawater cooling module, the second end is connected to the input end of the reaction chamber, and the third end is connected to the input end of the allocation chamber. The inner diameter of the first end is different from that of the second end, and the inner diameter of the second end is the same as that of the third end.

[0029] The beneficial effects of this invention are:

[0030] The seawater cooling system for a self-elevating platform provided by this invention includes a reaction chamber for docking with a seawater cooling module, allowing the seawater in the reaction chamber to cool the cooling module. A transfer chamber is also included to neutralize the heat from the seawater in the reaction chamber. A first connecting pipe connects the output of the seawater cooling module to the input of both the reaction chamber and the transfer chamber. The first connecting pipe controls the connection and disconnection of any two of the three components: the seawater cooling module, the reaction chamber, and the transfer chamber. A second connecting pipe connects the output of the reaction chamber to the input of the seawater cooling module. When the temperature of the seawater in the reaction chamber is low, the seawater cooling system of the self-elevating platform is in a first operating mode, where the first connecting pipe connects the seawater cooling module and the reaction chamber while blocking the connection between the seawater cooling module and the transfer chamber, and also blocking the connection between the transfer chamber and the reaction chamber. This allows seawater to circulate between the reaction chamber, the second connecting pipe, the seawater cooling module, and part of the first connecting pipe. When the temperature of the seawater in the reaction chamber is high and approaching the maximum operating temperature, the self-elevating platform... The seawater cooling system of the platform operates in a second mode. The first connecting pipe connects the seawater cooling module to the allocation chamber and seals off the seawater cooling module from the reaction chamber, as well as the allocation chamber from the reaction chamber. This allows seawater discharged from the cooling module to first enter the allocation chamber, where it neutralizes the temperature of the seawater in the reaction chamber used to cool the cooling module. Then, the allocation chamber and reaction chamber are connected, allowing seawater from the allocation chamber to flow into the reaction chamber. Combined with seawater from the reaction chamber flowing into the seawater cooling module via the second connecting pipe, this cycle repeats, utilizing the seawater in the allocation chamber to neutralize the heat in the reaction chamber, thus lowering the temperature and extending the usable time of the seawater in the reaction chamber. During this process, no seawater is discharged or introduced, meeting the cooling needs of the equipment in the reaction chamber when seawater cannot be drawn from the ocean. This does not change the weight of the jack-up platform, ensuring effective testing. Furthermore, the operating mode of the jack-up platform's lifting equipment can be adjusted according to actual needs to adapt to different seawater temperatures within the reaction chamber. Furthermore, the seawater cooling module, docking module, and second connecting pipe involved in the seawater cooling system of the self-elevating platform are all existing structures within the ship. When arranging the seawater cooling system of the self-elevating platform, only the first connecting pipe needs to be added to the existing structure of the ship to complete the assembly. This method is low-cost, simple to construct, highly safe, and highly reliable. Attached Figure Description

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0039] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0042] To ensure the safe operation of jack-up platforms, seawater cooling is required during operation. Specifically, the reaction chamber inside the jack-up platform draws seawater from the ocean to cool the platform. The heat-absorbing seawater is discharged into a seawater cooling module for further cooling, and once cooled, it is discharged overboard. During this process, the suction and discharge of seawater maintain a dynamic balance, ensuring that the weight of the jack-up platform remains constant. After construction is complete, a full-range lifting test is conducted to verify the platform's feasibility and reliability. This involves raising the jack-up platform from its lowest point to its highest point and then lowering it back down. To improve operational convenience, the full-range lifting test is typically conducted in shallow waters, such as at a dock. This means that the jack-up platform will leave the sea surface during the test. Once the jack-up platform rises to a certain height, the reaction chamber inside the platform can no longer pump seawater. At this point, the seawater temporarily stored in the reaction chamber cannot achieve a dynamic balance between seawater pumping and discharge. This not only fails to meet the actual cooling requirements but also changes the weight of the jack-up platform, making it impossible to effectively verify the connection quality of the jack-up platform.

[0043] To solve the above problems, such as Figure 1 and Figure 2As shown, this embodiment provides a seawater cooling system for a self-elevating platform. The seawater cooling system of the self-elevating platform includes a seawater cooling module 100, a docking module 200, a first connecting pipe 300, and a second connecting pipe 400. The seawater cooling module 100, docking module 200, and second connecting pipe 400 are all part of the ship's own structure. The seawater cooling module 100 has a cooling requirement. The docking module 200 includes a reaction chamber 210 and a transfer chamber 220. The seawater in the reaction chamber 210 is used to cool the seawater cooling module 100, and the seawater in the transfer chamber 220 is used to neutralize the heat of the seawater in the reaction chamber 210. The first connecting pipe 300 is configured to connect the output end of the seawater cooling module 100 to the input end of the reaction chamber 210 and the output end of the transfer chamber 220, respectively. The first connecting pipe 300 can control the connection and disconnection between any two of the three: the seawater cooling module 100, the reaction chamber 210, and the transfer chamber 220. The second connecting pipe 400 is configured to connect the output end of the reaction chamber 210 to the input end of the seawater cooling module 100.

[0044] The seawater cooling system of this self-elevating platform utilizes a reaction chamber 210 for docking with the seawater cooling module 100, allowing seawater within the reaction chamber 210 to cool the seawater cooling module 100. A transfer chamber 220 is also provided to neutralize the heat from the seawater within the reaction chamber 210. A first connecting pipe 300 connects the output of the seawater cooling module 100 to the input of both the reaction chamber 210 and the transfer chamber 220. The first connecting pipe 300 controls the connection and disconnection of any two of the three components: the seawater cooling module 100, the reaction chamber 210, and the transfer chamber 220. The output end of the reaction chamber 210 and the input end of the seawater cooling module 100 are connected by a second connecting pipe 400. When the seawater temperature inside the reaction chamber 210 is low, the seawater cooling system of the self-elevating platform is in the first working mode, that is, the first connecting pipe 300 connects the seawater cooling module 100 and the reaction chamber 210 and blocks the seawater cooling module 100 and the transfer compartment 220, as well as the transfer compartment 220 and the reaction chamber 210, so that the seawater circulates between the reaction chamber 210, the second connecting pipe 400, the seawater cooling module 100, and part of the first connecting pipe 300; when the seawater temperature inside the reaction chamber 210 is high and about to reach the maximum operating temperature... At this time, the seawater cooling system of the self-elevating platform is put into the second working mode. That is, the first connecting pipe 300 first connects the seawater cooling module 100 and the transfer chamber 220 and seals the seawater cooling module 100 and the reaction chamber 210, as well as the transfer chamber 220 and the reaction chamber 210. This allows the seawater discharged from the seawater cooling module 100 to first enter the transfer chamber 220. The seawater in the transfer chamber 220 neutralizes the temperature of the seawater in the reaction chamber 210 used to cool the seawater cooling module 100. Then, the transfer chamber 220 and the reaction chamber 210 are connected, allowing the seawater in the transfer chamber 220 to flow into the reaction chamber 210. Combined with the seawater in the reaction chamber 210 flowing along the second connecting pipe 400, the system is activated. The seawater cooling module 100 circulates repeatedly, using the seawater in the transfer tank 220 to neutralize the heat of the seawater in the reaction tank 210, thereby lowering the temperature of the seawater in the reaction tank 210 and extending its usable time. During this process, no seawater is discharged or introduced, meeting the cooling needs of the reaction tank 210 when it cannot draw seawater from the ocean. This does not change the weight of the jack-up platform, ensuring effective testing. Furthermore, the operating mode of the jack-up platform's lifting equipment can be adjusted according to actual needs to adapt to different seawater temperatures in the reaction tank 210. In addition, the seawater cooling module 100, docking module 200, and second connecting pipe 400 involved in the seawater cooling system of this jack-up platform are all existing structures within the vessel. When arranging the seawater cooling system for this jack-up platform, only the first connecting pipe 300 needs to be added to the existing ship structure to complete the assembly, resulting in low cost, simple construction, high safety, and strong reliability.

[0045] In this embodiment, the seawater cooling module 100 has a drive pump. When the reaction chamber 210 and the transfer chamber 220 are mutually blocked, the drive pump drives the seawater in the reaction chamber 210 to flow sequentially through the second connecting pipe 400, the seawater cooling module 100, and the first connecting pipe 300 before flowing into the transfer chamber 220. When the reaction chamber 210 and the transfer chamber 220 are mutually connected, the seawater in the transfer chamber 220 flows to the reaction chamber 210 along the first connecting pipe 300 using atmospheric pressure. When the seawater cooling system of the self-elevating platform is in its second operating mode, if the temperature of the seawater in the reaction chamber 210 is high and about to reach the maximum operating limit temperature, the drive pump of the seawater cooling module 100 will drive the seawater to flow into the transfer chamber 220, filling the transfer chamber 220 with mixed seawater. The high-temperature seawater will mix with the original low-temperature seawater in the transfer chamber 220 to lower the temperature. Then, combined with the mutual conduction between the reaction chamber 210 and the transfer chamber 220, the seawater in the transfer chamber 220 will flow to the reaction chamber 210 under the action of atmospheric pressure until the seawater levels in the reaction chamber 210 and the transfer chamber 220 are the same, thereby achieving the neutralization and cooling of the seawater in the reaction chamber 210.

[0046] To ensure the neutralization and cooling effect of the seawater in the allocation chamber 220 on the seawater in the reaction chamber 210, when no seawater flows into the allocation chamber 220, the volume of the seawater in the allocation chamber 220 is not less than one-quarter and not more than one-half of its own volume. This allows the reaction chamber 210 to drive enough seawater into the allocation chamber 220 for neutralization and cooling, while the allocation chamber 220 has a sufficient amount of pre-stored seawater for this purpose. It should be noted that in this embodiment, when no seawater flows into the allocation chamber 220, the volume of the seawater in the allocation chamber 220 is one-third of its own volume. In other embodiments, the volume of pre-stored seawater in the allocation chamber 220 can also be adjusted within the range of one-quarter to one-half of its own volume.

[0047] In one optional embodiment, the first connecting pipe 300 has a first end, a second end, and a third end. The first end connects to the output end of the seawater cooling module 100, the second end connects to the input end of the reaction chamber 210, and the third end connects to the input end of the allocation chamber 220. The inner diameter of the first end is different from that of the second end, and the inner diameter of the second end is the same as that of the third end. By providing a first end that connects to the output end of the seawater cooling module 100, a second end that connects to the input end of the reaction chamber 210, and a third end that connects to the input end of the allocation chamber 220 within the first connecting pipe 300, and by having a different inner diameter for the first end and the same inner diameter for the second end, a foolproof design for the first connecting pipe 300 is achieved, ensuring the correct assembly of the first connecting pipe 300. It should be noted that in this embodiment, the inner diameter of the first end is 300 mm, and the inner diameters of the second and third ends are both 250 mm. In other embodiments, the inner diameters of the first end, the second end, and the third end can be adjusted according to actual needs; this embodiment does not impose specific limitations.

[0048] Optionally, the seawater cooling system of the self-elevating platform also includes a temporary storage tank 500, wherein the temporary storage tank 500 is used to temporarily store the seawater discharged from the reaction chamber 210, and the second connecting pipe 400 includes a first connecting section and a second connecting section. The first connecting section is used to connect the output end of the reaction chamber 210 with the input end of the temporary storage tank 500, and the second connecting section is used to connect the output end of the temporary storage tank 500 with the input end of the seawater cooling module 100. By additionally equipping the seawater cooling system of the jack-up platform with a temporary storage tank 500 to temporarily store the seawater discharged from the reaction chamber 210, and by splitting the second connecting pipe 400 into a first connecting section and a second connecting section, the first connecting section connects the output end of the reaction chamber 210 to the input end of the temporary storage tank 500, and the second connecting section connects the output end of the temporary storage tank 500 to the output end of the seawater cooling module 100. This allows impurities to be deposited in the seawater discharged from the reaction chamber 210 before it enters the seawater cooling module 100, and regulates the flow rate of seawater entering the seawater cooling module 100, thereby improving the protection of the seawater cooling module 100. It should be noted that in this embodiment, the temporary storage tank 500 is also an existing structure of the ship, further reducing the assembly difficulty of the seawater cooling system of the jack-up platform.

[0049] Furthermore, the second connecting pipe 400 also includes a first loop control valve 410 and a second loop control valve 420. The first loop control valve 410 is located in the first connecting section within the second connecting pipe 400 and is used to unblock or block the first connecting section. The second loop control valve 420 is located in the second connecting section within the second connecting pipe 400 and is used to unblock or block the second connecting section. This allows for free control of the connection and isolation between the reaction chamber 210 and the temporary storage tank 500, as well as the connection and nuclear isolation between the temporary storage tank 500 and the seawater cooling module 100, further improving the ease of operation of the seawater cooling system of the jack-up platform. It should be noted that in this embodiment, the temporary storage tank 500 has a temperature sensor to accurately detect the temperature of the seawater discharged from the reaction chamber 210. When the temperature detected by the temperature sensor is low, the seawater cooling system of the jack-up platform is in a first operating mode; when the temperature detected by the temperature sensor reaches a preset temperature, the seawater cooling system of the jack-up platform is in a second operating mode. In this embodiment, the preset temperature is 34 degrees Celsius. In other embodiments, the specific value of the preset temperature can be adjusted according to actual needs. This embodiment does not impose any specific limitations.

[0050] As an optional solution, the first connecting pipe 300 includes a first connecting main pipe 310, a first connecting branch pipe 320, and a second connecting branch pipe 330. The first connecting main pipe 310 is connected to the output end of the seawater cooling module 100 and can control its own unblocking and blocking. The first connecting branch pipe 320 is connected to the first connecting main pipe 310 and the reaction chamber 210 respectively and can control its own unblocking and blocking. The second connecting branch pipe 330 is connected to the first connecting main pipe 310 and the allocation chamber 220 respectively and can control its own unblocking and blocking. By splitting the first connecting pipe 300 into a first connecting main pipe 310 and a first connecting branch pipe 320 and a second connecting branch pipe 330 respectively connected to the first connecting main pipe 310, the first connecting branch pipe 320 is connected to the reaction chamber 210, and the second connecting branch pipe 330 is connected to the allocation chamber 220. By combining the first connecting main pipe 310, the first connecting branch pipe 320 and the second connecting branch pipe 330, each of which can control its own unblocking and blocking, the effect of freely controlling the conduction and isolation of any two of the three components: the seawater cooling module 100, the reaction chamber 210 and the allocation chamber 220 is achieved.

[0051] Specifically, when it is necessary to connect only the seawater cooling module 100 and the reaction chamber 210, the first connecting main pipeline 310 and the first connecting branch pipeline 320 are kept open, while the second connecting branch pipeline 330 is blocked. When it is necessary to connect only the reaction chamber 210 and the transfer chamber 220, the first connecting branch pipeline 320 and the second connecting branch pipeline 330 are kept open, while the first connecting main pipeline 310 is blocked. When it is necessary to connect only the seawater cooling module 100 and the transfer chamber 220, the first connecting main pipeline 310 and the second connecting branch pipeline 330 are kept open, while the first connecting branch pipeline 320 is blocked.

[0052] In this embodiment, the first connecting main pipeline 310 has a first main pipeline control valve 311, which can be configured to unblock or block the first connecting main pipeline 310. The first connecting branch pipeline 320 has a first branch pipeline control valve 321, which is configured to unblock or block the first connecting branch pipeline 320. It should be noted that in this embodiment, the first connecting main pipeline 310 includes a first main branch section, a second main branch section, and a third main branch section connected sequentially. The first main branch section is connected to the output end of the seawater cooling module 100, and the third main branch section is connected to the first connecting branch pipeline 320 and the second connecting branch pipeline 330, respectively. The first main pipeline control valve 311 is located in the first main branch section and is used to unblock or block the first main branch section. The second main branch section has a second main pipeline control valve 312, which is used to unblock or block the second main branch section. The third main section has a third main pipeline control valve 313, which is used to unclog or block the third main section. The first main pipeline control valve 311, the second main pipeline control valve 312, and the third main pipeline control valve 313 are all solenoid valves. Solenoid valves have a simple structure, are easy to operate, and have a good blocking effect.

[0053] Furthermore, in this embodiment, the second main section, the third main section, the first connecting branch pipe 320, and the second connecting branch pipe 330 are all part of the existing structure of the ship. The first main section is an additional part added to the existing structure of the ship.

[0054] In an optional embodiment, the allocation compartment 220 includes at least one storage compartment, and the second connecting branch pipeline 330 includes at least one branch pipeline, each branch pipeline connecting a storage compartment and the first connecting main pipeline 310, each branch pipeline having a branch control valve, and each branch control valve being configured to unblock or block the corresponding branch pipeline.

[0055] It should be noted that in this embodiment, the allocation compartment 220 has a first storage compartment 221 and a second storage compartment 222, and the second connecting branch pipe 330 has a first branch pipe branch 331 and a second branch pipe branch 332. The first branch pipe branch 331 has a first branch control valve 3311, which can unblock or block the first branch pipe branch 331. The second branch pipe branch 332 has a second branch control valve 3321, which can unblock or block the second branch pipe branch 332. In other embodiments, the specific number of storage compartments and the specific number of branch pipes can be adjusted according to actual needs. This embodiment does not impose specific limitations. It should be noted that in this embodiment, both the first branch control valve 3311 and the second branch control valve 3321 are solenoid valves. Solenoid valves have a simple structure, are easy to operate, and have a good sealing effect.

[0056] As an optional solution, the seawater cooling system of the jack-up platform has at least two docking modules 200. Each docking module 200 includes a reaction chamber 210 and a transfer chamber 220. The first connecting pipeline 300 includes at least two first connecting branch pipelines 320 and at least two second connecting branch pipelines 330. Each first connecting branch pipeline 320 is connected to a reaction chamber 210 and a first connecting main pipeline 310, and each second connecting branch pipeline 330 is connected to a transfer chamber 220 and a first connecting main pipeline 310. By setting at least two sets of docking modules 200, each set of docking modules 200 includes a reaction chamber 210 and a transfer chamber 220, and at least two first connecting branch pipes 320 and second connecting branch pipes 330 are set in the first connecting pipe 300, so that each set of first reaction chambers 210 is connected to the first connecting main pipe 310 through a first connecting branch pipe 320, and each set of transfer chambers 220 is connected to the first connecting main pipe 310 through a second connecting branch pipe 330, the purpose of multiple sets of docking modules 200 alternately cooling the seawater cooling module 100 can be achieved, so as to further improve the cooling effect of the equipment to be cooled.

[0057] It should be noted that, in this embodiment, as Figure 2 As shown, the seawater cooling system of the jack-up platform has two sets of docking modules 200. The two sets of docking modules 200 follow a "one-for-one" design principle, meaning that under normal circumstances, only one set of docking modules 200 is in operation, while the other set is in standby mode. When the docking module 200 in operation fails, it is forced to stop working, and the standby module 200 switches to operation to maintain the normal operation of the jack-up platform's seawater cooling system. In other embodiments, the specific number of docking modules 200 can be adjusted according to actual needs; this embodiment does not impose a specific limitation.

[0058] Optionally, the seawater cooling module 100 has an overboard discharge pipe 110, with both ends of the overboard discharge pipe 110 connected to the output end of the seawater cooling module 100 and the overboard, respectively. The overboard discharge pipe 110 has a seawater discharge control valve 111 and an overboard discharge control valve 112 arranged sequentially. Both the seawater discharge control valve 111 and the overboard discharge control valve 112 can control the unblocking and blocking of the overboard discharge pipe 110. The seawater discharge control valve 111 is located on the side of the overboard discharge control valve 112 closer to the output end of the seawater cooling module 100. The discharge pipeline 110 includes a first part located between the seawater discharge control valve 111 and the output end of the seawater cooling module 100, a second part located between the seawater discharge control valve 111 and the overboard discharge control valve 112, and a third part located between the overboard discharge control valve 112 and the overboard. The first connecting main pipeline 310 in the first connecting pipeline 300 is connected to the second part to achieve the purpose of freely adjusting the output end of the seawater cooling module 100 to be connected to the overboard alone or to be connected to the first connecting main pipeline 310 alone.
