[0038] The present application will be further described in detail through specific embodiments in conjunction with the accompanying drawings.

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

[0040] As shown in Figure 1 and Figure 2 First, a detachable buoyancy base 2 is installed on the inner side of the cylindrical member 1 in an upright posture. 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, achieving the purpose of floating transportation.

[0041] The detachable buoyancy base 2 specifically comprises a seat body 21, a clamping assembly 22, and an inflatable water stop belt 23. The seat body 21 has cavities, air guide pipes communicating with the cavities and located above the cavities, and openings communicating with the cavities and located below the cavities. 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 guide pipe, or the high-pressure gas from outside can be filled into the cavity through the air guide pipe. 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 used to fix the seat body 21 to the inner side of the cylindrical member 1. The inflatable water stop belt 23 is arranged around the outer periphery of the seat body 21. When the inflatable water stop belt 23 is inflated, it is used to block the gap between the seat body 21 and the inner side of the cylindrical member 1, so as to close the bottom end opening of the cylindrical member 1, prevent water from seeping to the upper side of the detachable buoyancy base 2, and avoid causing the loss of buoyancy or accidental sinking of the cylindrical member 1.

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

[0044] The sinking positioning ship 3 is anchored at the sinking position by an anchoring system to prevent the sinking positioning ship 3 from being deviated by wind and waves. Then, a support limiting structure 31 on the sinking positioning ship 3 is abutted against the cylindrical member 1, so as to support and position the cylindrical member 1.

[0045] As shown in Figure 3As shown, the water inlet on the cylindrical member 1 is opened, and water is discharged to the inside of the cylindrical member 1. Due to the reduced buoyancy of the cylindrical member 1, the cylindrical member 1 starts to sink along the direction of gravity. When the bottom surface of the cylindrical member 1 is at a preset distance from the water bottom base, the water inlet on the cylindrical member 1 is closed, and the water discharge to the inside of the cylindrical member 1 is stopped, so that the cylindrical member 1 is kept in a floating state, which facilitates the adjustment of the position of the cylindrical member 1 before it contacts the water bottom base, thereby reducing the sinking error.

[0046] The left and right sinking positioning ships 3 are leveled by controlling the ballast water of the left and right sinking positioning ships 3, so as to level the water surface end of the cylindrical member 1. The leveling of the detachable buoyancy base 2 is realized by inflating or deflating the cavities of the detachable buoyancy base 2, so as to level the underwater end of the cylindrical member 1, so that the water surface end and the underwater end of the cylindrical member 1 are both in the vertical direction. Then, the anchoring position of the sinking positioning ship 3 is adjusted by the anchoring system, so as to drive the cylindrical member 1 to coincide with the sinking position, thereby improving the sinking positioning accuracy of the cylindrical member 1 and reducing the deviation of the cylindrical member 1.

[0047] As shown in Figure 4 The water inlet on the cylindrical member 1 is opened again, water is discharged to the inside of the cylindrical member 1, and the cylindrical member 1 continues to sink until the bottom surface of the cylindrical member 1 contacts the water bottom base. Under the action of the self-weight of the cylindrical member 1, the cylindrical member 1 continues to sink into the water bottom base until the cylindrical member 1 is completely supported on the water bottom base.

[0048] As shown in Figure 5 and Figure 6 When the detachable buoyancy base 2 is disassembled, part of the gas in the cavities of the detachable buoyancy base 2 is discharged, so that the buoyancy of the detachable buoyancy base 2 is less than its self-weight, thereby avoiding that the detachable buoyancy base 2 is supported on the cylindrical member 1 due to the buoyancy. Then, the inflatable water stop belt 23 is deflated, so as to remove the blockage of the inflatable water stop belt 23 to the gap between the seat body 21 and the inside of the cylindrical member 1, so that the upper space and the lower space of the detachable buoyancy base 2 are communicated. Then, the clamping assembly 22 is retracted to be separated from the cylindrical member 1, so as to realize the separation of the detachable buoyancy base 2 and the cylindrical member 1. Finally, the detachable buoyancy base 2 is lifted away from the cylindrical member 1, and the positioning and sinking of the cylindrical member 1 are completed.

[0049] In a specific embodiment of the present application, when the bottom surface of the cylindrical member 1 contacts the water bottom base, if the contact position deviates from the sinking position, the cavities of the detachable buoyancy base 2 can be inflated, so that the cylindrical member 1 is floated again and repositioned, thereby realizing the secondary adjustment of the sinking position of the cylindrical member 1.

[0050] In one specific embodiment of the present application, the sinking positioning ship 3 comprises at least two ship bodies 32, which are detachably connected to each other; each ship body 32 surrounds the outer periphery of the cylindrical member 1. The detachable connection between each ship body 32 can facilitate the quick folding and separation between each ship body 32, so as to surround the cylindrical member 1 at the center of the sinking positioning ship 3.

[0051] In one specific embodiment of the present application, the support limiting structure 31 comprises a support, an extension driving member, and a wheel. The support is connected to the ship body 32, the fixed end of the extension driving member is connected to the support, and the wheel is rotatably connected to the movable end of the extension driving member. The extension driving member is used to drive the wheel to extend, so as to abut against the cylindrical member 1. When the wheel abuts against the cylindrical member 1, the wheel can be in rolling contact with the cylindrical member 1, which can not only achieve the support and positioning of the cylindrical member 1, but also not generate additional resistance to the sinking of the cylindrical member 1.

[0052] In one specific embodiment of the present application, the outer periphery of the cylindrical member 1 is surrounded by a plurality of support limiting structures 31, and each support limiting structure 31 is further provided with a plurality of wheels. Each wheel is arranged along the axial direction of the cylindrical member 1, so as to form multi-point support in the axial direction of the cylindrical member 1, so as to disperse the pressure of each support point.

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

[0054] As shown in the drawings, Figure 3 In one specific embodiment of the present application, the preset distance from the bottom surface of the cylindrical member 1 to the water bottom base is not less than 0.5 m, so as to avoid the direct contact of the cylindrical member 1 to the water bottom base before accurate positioning, thereby bringing too much resistance to the position adjustment of the cylindrical member 1.

[0055] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
