The supporting and limiting structure on the sinking and positioning ship is then supported on the cylindrical component to support and position the cylindrical component. The water inlet on the cylindrical component is opened, and water is released to the inner side of the cylindrical component. As the buoyancy of the cylindrical component decreases, the cylindrical component begins to sink downward along the direction of gravity. When the bottom surface of the cylindrical component is sunk to a preset distance from the bottom bed, the water inlet on the cylindrical component is closed, and water is stopped from being released into the inside of the cylindrical component, so that the cylindrical component remains in a floating state, which is convenient for adjusting its position again before the cylindrical component contacts the bottom bed, thereby reducing the sinking error. The surface end of the cylindrical component is leveled by leveling the sinking and positioning ship; the detachable buoyancy base is leveled by inflating or exhausting air in each cavity of the detachable buoyancy base, thereby leveling the underwater end of the cylindrical component, so that the surface end and the underwater end of the cylindrical component are both in the vertical direction, and then by adjusting the anchoring position of the sinking and positioning ship, the cylindrical component is driven to coincide with the sinking position, thereby improving the sinking and positioning accuracy of the cylindrical component and reducing the displacement of the cylindrical component. Open the water inlet on the cylindrical component again, release water to the inside of the cylindrical component, and let the cylindrical component continue to sink until the bottom surface of the cylindrical component contacts the bottom bed; under the action of the deadweight of the cylindrical component, the cylindrical component continues to sink into the bottom bed until the cylindrical component is fully supported on the bottom bed. When disassembling the detachable buoyancy base, first discharge part of the gas in the cavity of the detachable buoyancy base so that the buoyancy of the detachable buoyancy base is less than its own weight, and avoid the detachable buoyancy base being supported on the cylindrical component due to buoyancy. Then deflate the inflatable waterstop to release the blockage of the inflatable waterstop on the gap between the seat body and the inner side of the cylindrical component, so that the upper space of the detachable buoyancy base is connected with the lower space. Then retract the clamping assembly to disengage from the cylindrical component, thereby realizing the separation of the detachable buoyancy base and the cylindrical component, and finally lift the detachable buoyancy base from the cylindrical component to complete the positioning and sinking of the cylindrical component.

[0038] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0039] To solve the technical problem of poor stability when sinking cylindrical components, such as Figures 1 to 6 As shown, the present application provides a floating sinking process of a cylindrical component, comprising the following steps:

[0040] like Figure 1 and Figure 2 As shown, first, a detachable buoyancy base 2 is installed on the inner side of the cylindrical member 1 in an upright posture, and the detachable buoyancy base 2 is used to close the bottom end opening of the cylindrical member 1 so that the cylindrical member 1 can float in the water in an upright posture to achieve the purpose of floating transportation.

[0041] The detachable buoyancy base 2 specifically includes a base body 21, a snap-on assembly 22, and an inflatable water stop 23. The base body 21 has a cavity, an air duct connected to the cavity and located above the cavity, and an opening connected to the cavity and located below the cavity. The number of cavities can be multiple, and each cavity is distributed in sequence along the circumferential direction. The air in the cavity can be discharged through the air duct, or external high-pressure gas can be filled into the cavity through the air duct. The opening is used to provide a channel for water to enter and exit the cavity.

[0042] The clamping assembly 22 is connected to the seat body 21 and is used to fix the seat body 21 to the inner side of the cylindrical member 1. The inflatable water stop 23 is arranged around the outer periphery of the seat body 21. When the inflatable water stop 23 is inflated, it is used to block the gap between the seat body 21 and the inner side of the cylindrical member 1 to close the bottom opening of the cylindrical member 1, prevent water from seeping to the top of the detachable buoyancy base 2, and avoid causing the buoyancy loss or accidental sinking of the cylindrical member 1.

[0043] A sinking and positioning ship 3 is arranged around the outer periphery of the cylindrical component 1, and the cylindrical component 1 is moved to the sinking position; the number of the sinking and positioning ships 3 can be two or more. When the number of the sinking and positioning ships 3 is two, the two sinking and positioning ships 3 are respectively located on the left and right sides of the cylindrical component 1, and the cylindrical component 1 is enclosed between the two sinking and positioning ships 3. The sinking and positioning ships 3 are used to accurately position the sinking of the cylindrical component 1.

[0044] The sinking and positioning ship 3 is anchored at the sinking position by the anchoring system to prevent the sinking and positioning ship 3 from being deflected by wind and waves. Then, the supporting and limiting structure 31 on the sinking and positioning ship 3 is supported on the cylindrical component 1 to support and position the cylindrical component 1.

[0045] like Figure 3As shown, the water inlet on the cylindrical member 1 is opened, and water is released into the inner side of the cylindrical member 1. As the buoyancy of the cylindrical member 1 decreases, the cylindrical member 1 begins to sink downward along the gravity direction. When the bottom surface of the cylindrical member 1 is sunk to a preset distance from the bottom of the water bed, the water inlet on the cylindrical member 1 is closed, and the water is stopped from being released into the inner side of the cylindrical member 1, so that the cylindrical member 1 remains in a floating state, which facilitates the adjustment of its position before the cylindrical member 1 contacts the bottom of the water bed, thereby reducing the sinking error.

[0046] By controlling the ballast water of the left and right sinking and positioning vessels 3, the left and right sinking and positioning vessels 3 are leveled to achieve the purpose of leveling the surface end of the cylindrical component 1. By inflating or exhausting air in each cavity of the detachable buoyancy base 2, the detachable buoyancy base 2 is leveled, thereby leveling the underwater end of the cylindrical component 1, so that the surface end and the underwater end of the cylindrical component 1 are both in the vertical direction, and then the anchoring position of the sinking and positioning vessel 3 is adjusted through the anchoring system to drive the cylindrical component 1 to coincide with the sinking position, thereby improving the sinking and positioning accuracy of the cylindrical component 1 and reducing the deviation of the cylindrical component 1.

[0047] like Figure 4 As shown, the water inlet on the cylindrical member 1 is opened again, and water is released into the inner side of the cylindrical member 1, so that the cylindrical member 1 continues to sink until the bottom surface of the cylindrical member 1 contacts the underwater base bed; under the action of the deadweight of the cylindrical member 1, the cylindrical member 1 continues to sink into the underwater base bed until the cylindrical member 1 is completely supported on the underwater base bed.

[0048] like Figure 5 and Figure 6 As shown, when disassembling the detachable buoyancy base 2, first discharge part of the gas in the cavity of the detachable buoyancy base 2, so that the buoyancy of the detachable buoyancy base 2 is less than its own weight, and avoid the detachable buoyancy base 2 being supported on the cylindrical member 1 due to buoyancy. Then, deflate the inflatable water stop 23, release the blockage of the gap between the seat body 21 and the inner side of the cylindrical member 1 by the inflatable water stop 23, and connect the upper space of the detachable buoyancy base 2 with the lower space. Then retract the clamping assembly 22 to disengage from the cylindrical member 1, so as to separate the detachable buoyancy base 2 from the cylindrical member 1, and finally lift the detachable buoyancy base 2 from the cylindrical member 1 to complete the positioning and sinking of the cylindrical member 1.

[0049] In a specific embodiment of the present application, when the bottom surface of the cylindrical component 1 contacts the bottom base bed, if the contact position deviates from the sinking position, air can be inflated into the cavity of the detachable buoyancy base 2 to make the cylindrical component 1 float again and reposition it, thereby achieving a secondary adjustment of the sinking position of the cylindrical component 1.

[0050] In a specific embodiment of the present application, the sinking and positioning ship 3 includes at least two hulls 32, and the adjacent hulls 32 are detachably connected; each hull 32 is arranged around the outer periphery of the cylindrical component 1. The detachable connection between the hulls 32 can facilitate the rapid closing and separation of the hulls 32, so as to surround the cylindrical component 1 at the center of the sinking and positioning ship 3.

[0051] In a specific embodiment of the present application, the support and limiting structure 31 includes a bracket, a telescopic drive member, and a support wheel. The bracket is connected to the hull 32, the fixed end of the telescopic drive member is connected to the bracket, the support wheel is rotatably connected to the movable end of the telescopic drive member, and the telescopic drive member is used to drive the support wheel to extend to support the cylindrical member 1. When the support wheel is supported on the cylindrical member 1, the support wheel can roll in contact with the cylindrical member 1, which not only realizes the support and positioning of the cylindrical member 1, but also does not generate additional resistance when the cylindrical member 1 sinks.

[0052] In a specific embodiment of the present application, a plurality of support and limiting structures 31 are provided on the outer periphery of the cylindrical member 1, and a plurality of supporting wheels are provided on each support and limiting structure 31. Each supporting wheel is arranged along the axial direction of the cylindrical member 1, thereby forming multi-point support in the axial direction of the cylindrical member 1 to disperse the pressure at each supporting point.

[0053] In a specific embodiment of the present application, the clamping assembly 22 includes a clamping claw and a clamping claw telescopic member. The clamping claw is slidably connected to the seat body 21, the fixed end of the clamping claw telescopic member is connected to the seat body 21, and the movable end of the clamping claw telescopic member is drivingly connected to the clamping claw. When the clamping claw telescopic member drives the clamping claw to extend out of the seat body 21, the clamping claw is used to clamp and fix with the cylindrical member 1, so as to fix the detachable buoyancy base 2 on the cylindrical member 1.

[0054] like Figure 3 As shown, in a specific embodiment of the present application, the preset distance from the bottom surface of the cylindrical component 1 to the underwater base bed is not less than 0.5m to prevent the cylindrical component 1 from directly contacting the underwater base bed before being accurately positioned, thereby causing excessive resistance to the position adjustment of the cylindrical component 1.

[0055] 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.
