Backpack type floating transportation installation process based on air floating structure

Abstract

According to the backpack type floating transportation and installation technology based on the air floating structure, cabin sealing water with the preset depth is loaded in the air floating structure with a bottomless cavity, and the air floating structure is kept in a partial floating state. Then the righting ship moves to the position over the air floating structure, buoyancy is increased by filling compressed air into the air floating structure, the air floating structure is promoted to float to make contact with a preset butt joint position at the bottom of the righting ship, and therefore when the righting ship moves, the air floating structure is driven by friction force between the righting ship and the air floating structure to move synchronously. And after the righting ship arrives at the target installation position, the anchoring system is started for positioning, exhausting is started, and the air floating structure sinks and is gradually separated from the righting ship. And after the air floating structure completes preliminary sinking under the action of self weight, an air extractor is started to implement negative pressure suction on the bottomless cavity, and the structure is further promoted to stably sink until the structure is completely in place. Finally, the air floating structure is completely separated from the righting ship, and the whole installation operation is completed.

Description

Technical Field

[0001] The present application belongs to the technical field of component transportation technology, and more specifically, relates to a backpack-type floating installation process based on an air flotation structure. Background Art

[0002] Air-floating structures can be transported and positioned on water without the need for heavy equipment such as large floating cranes. These structures utilize the buoyancy generated by air within their internal air chambers to maintain a stable floating position on the water surface. This simplifies the traditional installation process's reliance on heavy lifting equipment, reduces operating costs, and accelerates project progress.

[0003] During actual installation, performance is often constrained by complex and variable sea conditions. Specifically, during the installation phase, even minor fluctuations in the sea surface can cause the structure to tilt or shift. This instability not only disrupts the structure's vertical balance but also directly impacts the accuracy and efficiency of subsequent installation operations. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a backpack-type floating installation process based on an air flotation structure, so as to solve the technical problem in the prior art that the upright posture of the air flotation structure is easily affected by sea conditions during installation.

[0007] Loading a certain depth of battening water into an air flotation structure having a bottomless cavity, and keeping the air flotation structure at least partially floating on the water;

[0008] After the righting vessel moves to above the air-floating structure, it inflates the air-floating structure to increase its buoyancy, causing the air-floating structure to float up to a position where it docks with the bottom of the righting vessel. When the righting vessel moves, the friction between the air-floating structure and the righting vessel drives the air-floating structure to move.

[0009] After the righting vessel arrives at the installation location, it drops anchor and positions itself; the air-floating structure is deflated and sinks until it gradually separates from the righting vessel; as the air-floating structure sinks, the righting vessel rights the air-floating structure; when the air-floating structure sinks and tilts, the verticality is adjusted by controlling the exhaust volume of the air-floating structure or inflating the air in the air-floating structure;

[0010] After the air-floating structure finishes sinking due to its own weight, air is pumped into the bottomless cavity and the negative pressure continues to sink until the air-floating structure finishes sinking; the air-floating structure is completely separated from the righting vessel, and the installation of the air-floating structure is completed.

[0011] As a further improvement of the above technical solution:

[0013] Optionally, there are at least two righting ships, each of which is provided with an opening on one side, and each of the openings is sequentially enclosed to form an accommodating space for accommodating the cylindrical part, and the caisson part is located below each of the righting ships, and each of the righting ships is sequentially detachably connected; the righting ship also includes a cylinder support assembly and a caisson support member, and the cylinder support assembly includes a support member, which can move along the radial direction of the cylindrical part, thereby supporting the cylindrical part; one end of the caisson support member is connected to the righting ship, and the other end of the caisson support member is supported on the caisson part.

[0014] Optionally, the righting vessel includes a beam and a pair of hulls, one of the paired hulls is connected to one end of the beam, the other of the paired hulls is connected to the other end of the beam, and the beam and the paired hulls are arranged to form the opening.

[0015] Optionally, the righting vessels are arranged in pairs and are symmetrically arranged on both sides of the air floating structure.

[0016] Optionally, the cylinder support assembly includes a bracket and a telescopic drive member, the bracket is connected to the righting vessel and extends along the axial direction of the cylindrical portion; the fixed end of the telescopic drive member is connected to the bracket, and the support member is connected to the movable end of the telescopic drive member.

[0017] Optionally, the support member is a roller, and the roller is rotatably connected to the movable end of the telescopic driving member to be in rolling contact with the cylindrical portion.

[0018] Optionally, the number of the support members is at least two, and the support members are arranged on the bracket at intervals from each other along the vertical direction.

[0019] Optionally, it further includes a latch structure, which includes a slot, a latch and a latch driving component provided on the righting boat, the latch being provided on one side of the slot and capable of extending into the slot, and the latch being driven and connected to the latch driving component; the latch structure also includes a pin hole provided on another righting boat; when the righting boat is connected to the adjacent righting boat, the pin hole extends into the slot, and the latch driving component drives the latch to be inserted into the slot and the pin hole.

[0020] The beneficial effects of the backpack floating installation process based on the air flotation structure provided by this application are:

[0021] This application provides a backpack-type floating installation process based on an air-floating structure. This process involves loading a predetermined depth of water into an air-floating structure with a bottomless cavity, keeping the structure partially afloat. A righting vessel then moves directly above the structure and injects compressed air into the structure to increase buoyancy, forcing it to rise to a predetermined docking position on the bottom of the righting vessel. As the righting vessel moves, the friction between the two forces the structure to move synchronously. Once the righting vessel reaches the target installation location, the mooring system is activated for positioning. The air-floating structure is then controlled to vent air, allowing it to slowly sink and gradually separate from the righting vessel. During this period, a laser rangefinder mounted on the righting vessel monitors the structure's attitude in real time. If tilt is detected, the structure's vertical sinking is maintained by adjusting the venting rate of each compartment or selectively adding air. After the structure has initially sunk under its own weight, a vacuum pump is activated to apply negative pressure to the bottomless cavity, further promoting the structure's stable sinking until it is fully seated. Finally, the air flotation structure was completely separated from the righting vessel, completing the entire installation operation.

[0022] This installation process uses a righting vessel to guide and right the sinking installation of the air-floating structure, ensuring the upright posture of the air-floating structure, reducing the impact of sea conditions on the air-floating structure, and improving the installation accuracy and operation safety of the air-floating structure.

[0040] The present invention will be further described in detail below through specific embodiments with reference to the accompanying drawings.

[0041] This application provides a backpack-type floating installation process based on an air flotation structure. The specific implementation process is as follows:

[0042] like Figure 3 As shown, first, a predetermined depth of water is added to the air-floating structure 1 having a bottomless cavity, so that the air-floating structure 1 remains partially afloat. The righting vessel 2 then moves directly above the air-floating structure 1 and increases the buoyancy by injecting compressed air into the air-floating structure 1, causing the air-floating structure 1 to float up to a predetermined docking position on the bottom of the righting vessel 2 (e.g., Figure 1 As shown), when the righting vessel 2 moves, the friction between the two drives the air-floating structure 1 to move synchronously.

[0043] like Figure 2 As shown in FIG, when the righting vessel 2 arrives at the target installation position, the anchoring system is activated for positioning. Figure 4 As shown, the air-floating structure 1 then begins to be deflated, slowly sinking and gradually separating from the righting vessel 2. During the sinking process, the air-floating structure 1's attitude is monitored in real time by a laser rangefinder installed on the righting vessel 2. When a tilt is detected, the air-floating structure 1's vertical sinking state is maintained by adjusting the deflating rate of each compartment or selectively replenishing gas.

[0044] like Figure 5As shown, after the air-floating structure 1 initially sinks under its own weight, the vacuum device is activated to apply negative pressure to the bottomless cavity, further promoting the stable sinking of the structure until it is fully positioned. Finally, the air-floating structure 1 is completely separated from the righting vessel 2, completing the entire installation operation.

[0045] The installation process guides and straightens the sinking installation of the air-floating structure 1 by the straightening vessel 2, thereby ensuring the upright posture of the air-floating structure 1, reducing the impact of sea conditions on the air-floating structure 1, and improving the installation accuracy and operation safety of the air-floating structure 1.

[0046] In a specific embodiment of the present application, an air-floating structure 1 includes a caisson 11 and a cylindrical portion 12. The caisson 11 is located below the cylindrical portion 12. The caisson 11 has multiple bottomless cavities, the bottoms of which are water inlets connected to the outside. The caisson 11 is provided with exhaust valves connected to the cavities. After the air-floating structure 1 enters the water, sealing water enters the caisson 11, lowering the center of gravity of the air-floating structure 1 as a whole, providing floating stability for the air-floating structure 1, and also providing the necessary buoyancy for the entire air-floating component, allowing it to float on the water surface, thereby reducing the burden during transportation and improving transportation efficiency. The cylindrical portion 12 has a closed bottom and an open top, and is also provided with a water inlet valve. The caisson 11 is also provided with a water pumping hole for connecting to a negative pressure device to generate negative pressure in the cavity, causing the air-floating structure 1 to sink further under the help of the negative pressure. When the air-floating structure 1 is lowered for installation, the exhaust valve is opened to allow air in the cavity to be discharged through the exhaust valve, and water to enter the cavity through the water inlet. When the caisson 11 is completely submerged in water, the water inlet valve on the cylindrical portion 12 is opened to allow water to enter the cylinder, causing the entire air-floating structure 1 to sink.

[0047] In a specific embodiment of the present application, to ensure the stability of the air-floating structure 1 during transportation and installation, particularly the vertical stability of the cylindrical portion 12, at least two righting vessels 2 are provided. Each righting vessel 2 has an opening on one side, which, in turn, encloses a space for accommodating the cylindrical portion 12. The cylindrical portion 12 is loaded into this space and righted by the righting vessels 2, ensuring that it remains vertical during installation and avoiding safety hazards caused by shaking or tilting. The caisson portion 11 is located below each righting vessel 2, which is detachably connected in sequence to facilitate rapid closure and separation.

[0048] The righting vessel 2 also includes a cylinder support assembly 21 and a caisson support member 22. The cylinder support assembly 21 includes a support member that can move radially along the cylinder portion 12, thereby supporting the cylinder portion 12. This supports and rights the cylinder portion 12, ensuring the vertical stability of the air-floating structure 1 during installation.

[0049] One end of the caisson support member 22 is connected to the righting vessel 2, and the other end of the caisson support member 22 is supported on the caisson portion 11. Because the buoyancy provided by the caisson portion 11 is upward, while the gravity of the righting vessel 2 presses downward on the caisson portion 11, placing the caisson support member 22 between the caisson portion 11 and the righting vessel 2 not only ensures the stability of the air-floating structure 1, but also effectively reduces wear by reducing the contact area, thereby extending the service life of the structure.

[0050] In one embodiment of the present application, the righting vessel 2 is a catamaran structure, specifically comprising a crossbeam and paired hulls. The hulls float on the water surface due to their own buoyancy. One of the paired hulls is connected to one end of the crossbeam, and the other of the paired hulls is connected to the other end of the crossbeam. The crossbeam and paired hulls enclose an opening. The top view of the righting vessel 2 can be specifically H-shaped, U-shaped, or the like.

[0051] In a specific embodiment of the present application, the righting vessels 2 are arranged in pairs and are symmetrically arranged on both sides of the air-floating structure 1, thereby forming effective support on both sides of the air-floating structure 1 to ensure that the air-floating structure 1 is in a vertical state.

[0052] In one specific embodiment of the present application, the cylinder support assembly 21 comprises a bracket and a telescopic drive. The bracket is connected to the righting vessel 2 and extends along the axis of the cylindrical portion 12, providing a support platform for the telescopic drive. The fixed end of the telescopic drive is connected to the bracket, and the support member is connected to the movable end of the telescopic drive. The telescopic motion of the telescopic drive achieves radial support and adjustment of the air-floating structure 1. The telescopic drive can be a hydraulic / pneumatic cylinder, an electric push rod, or the like.

[0053] In one specific embodiment of the present application, the support member is a roller rotatably connected to the movable end of the telescopic drive member, thereby rolling in contact with the cylindrical portion 12. Under the influence of natural factors such as waves or tides, the air-floating structure 1 may experience a certain degree of up-and-down movement. The rolling contact between the roller and the air-floating structure 1 effectively adapts to these dynamic changes, ensuring that the support member maintains contact and support with the air-floating structure 1 at all times.

[0054] In a specific embodiment of the present application, the number of support members is at least two, and each support member is arranged on the bracket at intervals along the vertical direction, so that each support member can form multi-point support in the axial direction of the air-floating structure 1, which not only enhances the rigidity and stability of the entire operating system, but also effectively reduces the concentrated stress and deformation caused by single-point support, thereby extending the service life of the equipment.

[0055] In a specific embodiment of the present application, the righting ship 2 further includes a latch structure, which includes a slot, a latch, and a latch driver provided on the righting ship 2. The latch is provided on one side of the slot and can be inserted into the slot. The latch is driven and connected to the latch driver. The latch structure also includes a pin hole provided on another righting ship 2. When the righting ship 2 is combined and connected with an adjacent righting ship 2, the pin hole is inserted into the slot, and then the latch driver drives the latch to be inserted into the slot and the pin hole, thereby achieving locking between the two adjacent righting ships 2. This latch connection method is not only simple and convenient to operate, but also has good connection strength and stability, and can effectively resist the impact of wind and waves and vibration in various complex marine environments.

[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
