[0023] The floating stable compartment device of the present application includes a compartment body, an inflatable waterstop and a telescopic limiting structure. The compartment body has a cavity and a vent. The bottom end of the cavity has an opening, which serves as a passage connecting the internal and external environments of the cavity, allowing the exchange of air and fluid. The vent is connected to the top of the cavity, through which air can be filled into or discharged from the cavity to achieve regulation of the internal pressure of the cavity. The inflatable waterstop surrounds the outer circumference of the compartment body. When the inflatable waterstop is in an inflated state, it can contact the external circumferential surface to form a seal.

[0044] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0045] In order to improve the stability of the sinker during floating and towing and reduce its swaying, Figures 1 to 5 As shown, the present application provides a floating stable partition device, including a partition body 1, an inflatable waterstop 2 and a telescopic limiting structure 3.

[0046] The compartment body 1 is the main structure of the floating stable compartment device, which has a cavity 11 and a vent 12. The bottom end of the cavity 11 has an opening 13, which serves as a passage connecting the internal and external environments of the cavity 11, allowing the exchange of air and fluid. The vent 12 is connected to the top of the cavity 11, through which air can be filled or discharged into the cavity 11 to achieve the regulation of the internal pressure of the cavity 11.

[0047] The inflatable water stop 2 surrounds the outer circumference of the compartment body 1. When the inflatable water stop 2 is inflated, it can contact the outer circumferential surface to form a seal. When the seal needs to be released, it is only necessary to discharge the gas in the inflatable water stop 2 to reduce its volume, so that it can be separated from the outer circumferential surface, which is convenient for the disassembly and redeployment of the floating stable compartment device.

[0048] The telescopic limiting structure 3 is arranged on the compartment body 1, and specifically includes a telescopic driving member 31 and a limiting member 32. The fixed end of the telescopic driving member 31 is connected to the compartment body 1, and the movable end of the telescopic driving member 31 is connected to the limiting member 32. Through the telescopic action of the telescopic driving member 31, the limiting member 32 is controlled to move along the radial direction of the compartment body 1. When the limiting member 32 is extended and inserted into the external card slot, the floating stable compartment device is firmly connected to the external structure, ensuring reliable fixation in complex sea conditions.

[0049] The floating stable compartment device of the present application is used in conjunction with the hollow cylinder 5 when actually used. The two ends of the hollow cylinder 5 are connected, and the floating stable compartment device is arranged horizontally on the inner side of the hollow cylinder 5, dividing the inner side of the hollow cylinder 5 into a buoyancy chamber 51 and a water inlet chamber 52 arranged from top to bottom. The buoyancy chamber 51 is responsible for providing sufficient buoyancy to ensure that the entire system can always float on the water surface when floating and towing; the water inlet chamber 52 is used to load stable water, and the loading amount of stable water is adjusted by inflating or exhausting the vent pipe 12, thereby achieving the purpose of lowering the center of gravity of the system to reduce the swing of the hollow cylinder 5.

[0050] In actual operation, the floating stable compartment device is first hoisted to the inside of the hollow cylinder 5, and then the limiter 32 of the telescopic limit structure 3 is driven to extend and engage with the slot on the inner side of the hollow cylinder 5 to achieve the connection and installation of the floating stable compartment device. Next, the inflatable water stop 2 is inflated to expand and fit on the inner wall of the hollow cylinder 5, thereby separating the buoyancy chamber 51 and the water inlet chamber 52 arranged up and down. Then, the vent pipe 12 is opened, and the air in the water inlet chamber 52 and the cavity 11 is discharged by gravity, and the external liquid immediately flows into the water inlet chamber 52 to form a stable water layer. By loading stable water in the water inlet chamber 52, not only the center of gravity height of the hollow cylinder 5 is reduced, and the torque when it swings and shakes is reduced, but also the water height of the hollow cylinder 5 can be reduced, and the influence of wind and waves on the hollow cylinder 5 can be reduced, thereby improving the stability of the hollow cylinder 5. In addition, by inflating or exhausting air into the snorkel 12, the amount of stable water loaded can be adjusted to adapt to different sea conditions.

[0051] like Figure 1 and Figure 2 As shown, in a specific embodiment of the present application, the compartment body 1 specifically includes a top plate portion 14, a side plate portion 15 and a bottom plate portion 16. The top plate portion 14 is a top covering element of the cavity 11, which is connected to the top end of the side plate portion 15; the bottom plate portion 16 is connected to the bottom end of the side plate portion 15, and the top plate portion 14, the side plate portion 15 and the bottom plate portion 16 enclose the cavity 11, and the opening 13 is specifically provided on the bottom plate portion 16.

[0052] like Figure 5As shown, in a specific embodiment of the present application, the bottom plate portion 16 specifically includes an inner ring bottom plate portion and an outer ring bottom plate portion arranged on the same plane, and the opening 13 is an annular opening, sandwiched between the inner ring bottom plate portion and the outer ring bottom plate portion.

[0053] When the floating stable compartment device is tilted, the opening 13 can minimize the leakage of gas in the cavity 11, thereby ensuring the buoyancy stability of the floating stable compartment device in the tilted state. The reserved space in the cavity 11 can meet the requirements of free movement of the water body, thereby reducing the water seal height requirements of the hollow cylinder 5 during floating and towing, thereby reducing the overall height of the floating stable compartment device and reducing the amount of materials used.

[0054] like Figure 1 and Figure 4 As shown, in a specific embodiment of the present application, the side plate portion 15 is specifically a conical side plate portion, the large end of the conical side plate portion is connected to the top plate portion 14, and the small end of the conical side plate portion is connected to the bottom plate portion 16. When it is necessary to hoist the floating stable compartment device into the hollow cylinder 5, the conical structure of the conical side plate portion can guide the floating stable compartment device to smoothly enter the cylinder, avoiding jamming or collision problems, thereby improving the efficiency and safety of the hoisting process and reducing the difficulty and risk of operation.

[0055] like Figure 5 As shown, in a specific embodiment of the present application, the compartment body 1 further includes a partition 17, which is disposed in the cavity 11; there are multiple partitions 17, and each partition 17 divides the cavity 11 into multiple sub-cavities arranged along the circumferential direction. The cavity 11 is divided into multiple sub-cavities by the partition 17, so that the area of ​​the free water surface is greatly reduced, which helps to reduce the interference of the floating stable compartment device in the fluid due to fluctuations, thereby enhancing the overall stability, so that the floating stable compartment device can maintain a more stable working state in a complex and changeable water environment.

[0056] like Figure 2 As shown, in a specific embodiment of the present application, the side plate portion 15 is provided with a mounting groove 151, and the pneumatic waterstop 2 is installed in the mounting groove 151. By installing the pneumatic waterstop 2 in the mounting groove 151, a close fit and a firm connection between the two are achieved, which not only ensures that the pneumatic waterstop 2 can fully exert its sealing performance, but also effectively prevents potential safety hazards caused by improper installation or looseness.

[0057] like Figure 2As shown, in a specific embodiment of the present application, the telescopic limiting structure 3 further includes a telescopic guide member 33, and the telescopic guide member 33 is connected to the top plate portion 14. The telescopic guide member 33 has a guide groove 331 extending along the radial direction of the compartment body 1. Through the guidance of the guide groove 331, the limiting member 32 can slide along a predetermined path, thereby realizing the control of the telescopic movement of the limiting member 32.

[0058] like Figure 3 As shown, in a specific embodiment of the present application, there are multiple telescopic limit structures 3, and each telescopic limit structure 3 is arranged at intervals from each other along the circumferential direction. By providing multiple telescopic limit structures 3, effective load dispersion can be achieved. When the limit member 32 performs telescopic movement, each telescopic limit structure 3 can jointly bear the stress and impact force generated thereby, thereby avoiding damage or failure caused by a single structure being subjected to excessive load.

[0059] In a specific embodiment of the present application, the floating stable bulkhead device further includes a lifting lug 4, which serves as a connecting piece and is connected to the bulkhead body 1 to facilitate the connection between the floating stable bulkhead device and the lifting equipment.

[0060] like Figures 6 to 8 As shown, the present application also provides a floating cylinder structure, including a hollow cylinder 5 and the floating stabilization partition device in the above-mentioned embodiment, the two ends of the hollow cylinder 5 are connected, and the floating stabilization partition device is horizontally arranged on the inner side of the hollow cylinder 5 to divide the inner side of the hollow cylinder 5 into a buoyancy chamber 51 and a water inlet chamber 52 arranged from top to bottom, and the water inlet chamber 52 is used to load floating stabilization water.

[0061] In actual operation, the floating stable compartment device is first hoisted to the inside of the hollow cylinder 5, and then the limiter 32 of the telescopic limit structure 3 is driven to extend and engage with the slot on the inner side of the hollow cylinder 5 to achieve the connection and installation of the floating stable compartment device. Next, the inflatable water stop 2 is inflated to expand and fit on the inner wall of the hollow cylinder 5, thereby separating the buoyancy chamber 51 and the water inlet chamber 52 arranged up and down. Then, the vent pipe 12 is opened, and the air in the water inlet chamber 52 and the cavity 11 is discharged by gravity, and the external liquid immediately flows into the water inlet chamber 52 to form a stable water layer. By loading stable water in the water inlet chamber 52, not only the center of gravity height of the hollow cylinder 5 is reduced, and the torque when it swings and shakes is reduced, but also the water height of the hollow cylinder 5 can be reduced, and the influence of wind and waves on the hollow cylinder 5 can be reduced, thereby improving the stability of the hollow cylinder 5. In addition, the amount of stable water can be adjusted to adapt to different sea conditions by inflating or exhausting air into the vent pipe 12. Since the floating tube structure of the present application has the floating stable compartment device in the above embodiment, it also has the advantages of the floating stable compartment device in the above embodiment.

[0062] like Figure 6 As shown, in a specific embodiment of the present application, the hollow cylinder 5 includes a slot structure 53 provided on the inner wall. The slot structure 53 includes an upper flange 531, a lower flange 532, and a slot 533 provided between the upper flange 531 and the lower flange 532. The telescopic limiting structure 3 of the floating stable compartment device is inserted into the slot 533 to separate the inner side of the hollow cylinder 5 into a buoyancy chamber 51 and a water entry chamber 52 arranged from top to bottom.

[0063] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
