Description

Technical Field

[0001] The present application belongs to the technical field of component transportation, and more specifically, to a floating stabilization method for cylindrical components. Background Art

[0002] As an important structure, cylindrical components are widely used in submarine pipeline laying, offshore platform infrastructure construction, underwater tunnel construction, etc. There are many challenges in transporting cylindrical components from the manufacturing site to the installation site.

[0003] Since cylindrical components are generally large in size and deadweight, traditional methods of transportation often rely on large-scale lifting facilities for lifting operations. These facilities are not only expensive to rent and use, but also in some remote or deep-sea areas, the accessibility and operability of large floating cranes are limited, further increasing the complexity and cost of transportation.

[0004] Therefore, how to ensure the safety and stability of transportation while effectively reducing the dependence on large lifting equipment during transportation and reducing transportation costs has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a floating stabilization method for cylindrical components to solve the technical problems existing in the prior art of difficult and high transportation costs of cylindrical components.

[0008] The cylindrical components are loaded onto the semi-submersible barge;

[0009] A compartment structure is installed inside the cylindrical component, wherein the compartment structure divides the cylindrical component into a buoyancy compartment and a stabilization compartment arranged up and down, wherein the buoyancy compartment is located above the compartment structure and the stabilization compartment is located below the compartment structure;

[0010] The semi-submersible barge starts to dive, and the cylindrical member is forced to press the stabilizing water of the initial liquid level into the stabilizing tank under the action of its own weight;

[0011] The air pipe on the compartment structure is opened to exhaust the air in the stabilizing compartment; under the deadweight of the cylindrical component, water continues to flow into the stabilizing compartment until the liquid level is flush with the bottom surface of the compartment structure, and then the air pipe on the compartment structure is closed;

[0012] After the compartment structure contacts the liquid surface, buoyancy is generated, so that it floats upward and presses against the cylindrical component;

[0013] The semi-submersible barge continues to dive, and under the action of the deadweight of the cylindrical component and the partition structure, stable water of the secondary liquid level height is forced into the cavity of the stable chamber and the partition structure until the gravity of the cylindrical component and the partition structure is balanced with the buoyancy of the cylindrical component and the partition structure, so that the cylindrical component floats in the water.

[0014] As a further improvement of the above technical solution:

[0015] Optionally, air is inflated into the cavity of the compartment structure through an air pipe on the compartment structure to discharge the stable water in the cavity of the compartment structure, thereby increasing the buoyancy of the cylindrical component and causing the cylindrical component to float to a certain height;

[0016] The semi-submersible barge continues to dive to achieve separation of the semi-submersible barge from the cylindrical component.

[0017] Optionally, the liquid level in the cavity of the compartment structure is at least 1.5 m lower than the liquid level in the stabilizing compartment.

[0018] Optionally, the cylindrical component is a hollow cylindrical component, and the inner wall of the hollow cylindrical component has a slot structure. When the compartment structure is snapped into the slot structure, the hollow cylindrical component is divided into a buoyancy compartment and a stabilization compartment which are arranged up and down.

[0019] Optionally, the slot structure includes a slot and flanges provided on upper and lower sides of the slot, and the compartment structure is snapped into the slot to separate the cylindrical component into a buoyancy compartment and a stabilization compartment arranged up and down.

[0020] Optionally, the partition structure includes a bin body and a snap-in assembly, the bin body is provided with a slide groove, the snap-in assembly includes a slider and a telescopic member, the slider is slidably connected in the slide groove, one end of the telescopic member is connected to the bin body, and the other end of the telescopic member is drivingly connected to the slider, and the telescopic member is used to drive the slider to extend out of the bin body so as to snap into the slot.

[0021] Optionally, the cavity of the partition structure is arranged in the bin body, and the bottom end of the cavity has an opening, and the opening is annular to separate the bottom plate of the partition structure into an inner circle bottom plate portion and an outer circle bottom plate portion.

[0022] Optionally, after the cylindrical component sinks to a liquid level flush with the bottom surface of the compartment structure, the inflatable waist seal arranged around the outer circumference of the compartment structure is inflated until it expands and contacts the inner wall of the cylindrical component to seal the stabilization compartment.

[0023] Optionally, the partition structure also includes a laser rangefinder, which is installed on the warehouse body and is used to measure the distance of the partition structure relative to the center of the cylindrical component, so as to adjust the extension amount of the telescopic member so that the partition structure is coaxial with the cylindrical component.

[0024] The beneficial effects of a floating stabilization method for a cylindrical component provided by the present application are:

[0025] The floating stabilization method for cylindrical components provided in the present application first loads the cylindrical components onto a semi-submersible barge with sufficient carrying capacity. A partition structure is installed on the inner side of the cylindrical component, and the partition structure divides the cylindrical component into a buoyancy compartment and a stabilization compartment arranged up and down. Among them, the buoyancy compartment is located above the partition structure, and the stabilization compartment is located below the partition structure; the buoyancy compartment is used to ensure that the cylindrical component has sufficient buoyancy to enable the cylindrical component to float on the water surface, thereby realizing the floating transportation of the cylindrical component. The stabilization compartment is used to load stabilization water to ensure that the cylindrical component has a certain stability when floating on the water surface. The semi-submersible barge begins to dive, and the cylindrical component is forced to press stabilization water of the initial liquid level height into the stabilization compartment under the action of its own weight; the air pipe on the partition structure is opened to discharge the air in the stabilization compartment; under the action of the dead weight of the cylindrical component, water continues to enter the stabilization compartment. When the liquid level is flush with the bottom surface of the partition structure, the air pipe on the partition structure is closed; the buoyancy generated by the partition structure after contacting the liquid surface forces the partition structure to float upward, thereby pressing against the cylindrical component; the semi-submersible barge continues to dive, and under the action of the dead weight of the cylindrical component and the partition structure, stable water of the secondary liquid level height is forced to be pressed into the cavity of the stabilizing chamber and the partition structure until the gravity of the cylindrical component and the partition structure is balanced with the buoyancy of the cylindrical component and the partition structure, so that the cylindrical component floats in the water.

[0026] Therefore, only a small tonnage tugboat is needed to tow the cylindrical component to the designated sea area, and no large loading ship is needed to carry the cylindrical component, thereby reducing the transportation difficulty and transportation cost of the cylindrical component. In addition, when the stabilizing tank is filled with stable water, it has a certain floating stability, thereby ensuring its transportation safety in various sea conditions.

[0051] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0052] The present application provides a floating stabilization method for a cylindrical component, comprising the following steps:

[0053] like Figure 1 and Figure 2 As shown, first, the cylindrical component 1 is loaded onto a semi-submersible barge 2 with sufficient carrying capacity. A compartment structure 3 is installed inside the cylindrical component 1, and the compartment structure 3 divides the cylindrical component 1 into a buoyancy compartment 11 and a stabilization compartment 12 arranged up and down. Among them, the buoyancy compartment 11 is located above the compartment structure 3, and the stabilization compartment 12 is located below the compartment structure 3; the buoyancy compartment 11 is used to ensure that the cylindrical component 1 has sufficient buoyancy so that the cylindrical component 1 can float on the water surface, thereby realizing the floating transportation of the cylindrical component 1. The stabilization compartment 12 is used to load stabilization water to ensure that the cylindrical component 1 has a certain stability when floating on the water surface.

[0054] The semi-submersible barge 2 starts to dive, and the cylindrical component 1 is forced to press the stable water of the initial liquid level into the stable chamber 12 under its own weight;

[0055] The air pipe on the compartment structure 3 is opened to exhaust the air in the stable compartment 12; under the self-weight of the cylindrical component 1, water continues to flow into the stable compartment 12. Figure 3 As shown, when the liquid level is flush with the bottom surface of the compartment structure 3, the air pipe on the compartment structure 3 is closed;

[0056] After the compartment structure 3 contacts the liquid surface, the buoyancy generated therefrom forces the compartment structure 3 to float upward, thereby pressing against the cylindrical component 1;

[0057] like Figure 4 and Figure 5 As shown, the semi-submersible barge 2 continues to dive, and under the action of the deadweight of the cylindrical component 1 and the partition structure 3, stable water of the secondary liquid level height is forced into the cavity of the stabilizing chamber 12 and the partition structure 3 until the gravity of the cylindrical component 1 and the partition structure 3 is balanced with the buoyancy of the cylindrical component 1 and the partition structure 3, so that the cylindrical component 1 floats in the water.

[0058] Therefore, only a small tonnage tugboat is needed to tow the cylindrical component 1 to the designated sea area, and no large loading vessel is needed to carry the cylindrical component 1, thereby reducing the transportation difficulty and transportation cost of the cylindrical component 1. In addition, when the stabilizing tank 12 is filled with stabilizing water, it has a certain floating stability, thereby ensuring its transportation safety in various sea conditions.

[0059] like Figure 6 As shown, in a specific embodiment of the present application, air is inflated into the cavity of the partition structure 3 through the air pipe on the partition structure 3 to discharge the stable water in the cavity of the partition structure 3, thereby increasing the buoyancy of the cylindrical component 1 and making the cylindrical component 1 float to a certain height; as the semi-submersible barge 2 continues to dive, the semi-submersible barge 2 and the cylindrical component 1 can be automatically separated.

[0060] like Figure 6 and Figure 7 As shown, in a specific embodiment of the present application, the liquid level in the cavity of the compartment structure 3 is at least 1.5m lower than the liquid level in the stabilizing chamber 12. This setting is based on preventing the water level in the cavity of the compartment structure 3 from rising and posing a threat to the stability of the system under extreme working conditions, such as sudden influx of water or changes in external pressure. By ensuring that the water surface in the compartment structure 3 is at least 1.5m lower than the water surface of the sealed chamber, a sufficient safety buffer area is provided for the system, thereby ensuring the stability and safety of the overall structure.

[0061] like Figure 7 As shown, in a specific embodiment of the present application, the cylindrical member 1 is specifically a hollow cylindrical member, and both ends of the hollow cylindrical member are open. The inner wall of the hollow cylindrical member has a slot structure 13, and when the compartment structure 3 is connected to the slot structure 13, the hollow cylindrical member can be divided into a buoyancy compartment 11 and a stabilization compartment 12 arranged up and down.

[0062] like Figure 7 As shown, in a specific embodiment of the present application, the slot structure 13 includes a slot 131 and flanges 132 provided on the upper and lower sides of the slot 131. The flange 132 plays a role of limiting the position with the compartment structure 3 and transmitting force. When the compartment structure 3 is connected to the slot 131, the cylindrical component 1 is divided into a buoyancy compartment 11 and a stabilization compartment 12 arranged up and down.

[0063] like Figure 7 As shown, in a specific embodiment of the present application, the compartment structure 3 includes a compartment body 31 and a snap-on assembly 32. Specifically, a slide groove 311 is provided on the compartment body 31, which provides a precise moving path for the snap-on assembly 32 and ensures the smoothness and stability of the snap-on process. The snap-on assembly 32 includes a slider 321 and a telescopic member 322. The slider 321 is slidably connected to the slide groove 311, one end of the telescopic member 322 is connected to the compartment body 31, and the other end of the telescopic member 322 is drivingly connected to the slider 321. The telescopic member 322 is used to drive the slider 321 to extend out of the compartment body 31 so as to snap into the slot 131. The telescopic member 322 can specifically be a hydraulic / pneumatic cylinder or an electric push rod, etc.

[0064] like Figure 7As shown, in a specific embodiment of the present application, the cavity of the partition structure 3 is arranged in the bin body 31, and the bottom end of the cavity has an opening, which is annular to separate the bottom plate of the partition structure 3 into an inner circle bottom plate portion and an outer circle bottom plate portion.

[0065] When the floating stable compartment device is tilted, the annular opening can minimize the leakage of gas in the cavity, thereby ensuring the buoyancy stability of the floating stable compartment device in the tilted state. The reserved space in the cavity can also meet the requirements of free movement of the water body, thereby reducing the water seal height requirements of the cylindrical component 1 during floating and towing, thereby reducing the overall height of the compartment structure 3 and reducing the amount of materials used.

[0066] like Figure 7 As shown, in a specific embodiment of the present application, after the cylindrical component 1 sinks to the liquid level and is flush with the bottom surface of the partition structure 3, the inflatable waist seal 33 arranged around the outer circumference of the partition structure 3 is inflated until it expands and contacts the inner wall of the cylindrical component 1 to seal the stabilization chamber 12, so as to effectively prevent the water in the stabilization chamber 12 from seeping into the buoyancy chamber 11.

[0067] like Figure 7 As shown, in a specific embodiment of the present application, the compartment structure 3 also includes a laser rangefinder 34, which is installed on the compartment body 31 and is used to measure the distance of the compartment structure 3 relative to the center of the cylindrical member 1. In actual operation, the laser rangefinder 34 will continuously emit a laser beam and receive the signal reflected back. By calculating parameters such as the round-trip time or phase difference of the laser beam, the relative distance between the current position of the compartment structure 3 and the center of the cylindrical member 1 can be determined. Once the system detects that the compartment structure 3 has a deviation from the center position of the cylindrical member 1, it will then feed back this deviation signal to the control system, automatically calculate the value that needs to be adjusted, and adjust the extension length of the telescopic member 322 accordingly, thereby effectively calling back the compartment structure 3 to a coaxial state with the cylindrical member 1.

[0068] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
