[0002] In recent years, my country has conducted numerous practices and explorations in deep-sea aquaculture equipment. Currently, domestic aquaculture equipment companies possess rich experience in equipment construction and have independently developed many large-scale deep-sea aquaculture equipment products. Due to site limitations and design requirements, large-scale deep-sea aquaculture equipment is mostly built on slipways or in docks. With the increasing size of deep-sea aquaculture cages, the launching process of aquaculture equipment has become a key concern during construction. Currently, the Chinese industry is capable of designing and constructing various types of offshore aquaculture facilities, including bottom-mounted, semi-submersible, and floating structures. The main carriers of large-scale industrialized deep-sea aquaculture equipment are large-scale intelligent deep-sea cages and aquaculture vessels. Large-scale deep-sea aquaculture platforms (cages) are currently a widely explored method of deep-sea aquaculture, primarily launched from docks or semi-submersible vessels.

[0003] The safe launch of tubular aquaculture platforms is one of the key issues restricting their construction. Due to the requirements of aquaculture functions, aquaculture platforms have a more dispersed main structure and greater width compared to traditional ships, making launch more difficult and demanding higher safety standards. Furthermore, with the increasing size of aquaculture platforms, the construction work requires increasingly larger sites, while domestic resources of large dry docks and floating docks are limited and expensive.

[0022] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0023] This embodiment provides a launching support device for a deep-sea aquaculture platform, such as... Figure 1 , Figure 2 As shown, it includes: A pontoon 1 is used to be placed at the bottom of the aquaculture platform 2; the pontoon 1 has several hollow ballast tanks 11; Support 3 is located between the floating box 1 and the aquaculture platform 2. The support 3 is used to support the frame tube 201 at the bottom of the aquaculture platform 2. Several airbags 4 are located at the bottom of the float box 1; The water inlet and outlet system is used to introduce liquid into the ballast tank 11 to make the float 1 sink, or to discharge liquid from the ballast tank 11 to make the float 1 float.

[0024] The pontoon 1 is a box with several hollow ballast tanks 11. When the ballast tanks 11 contain only gas, the pontoon 1 provides sufficient buoyancy to lift the aquaculture platform 2 above the water surface. When the ballast tanks 11 are filled with liquid, such as water, the weight of the pontoon 1 increases significantly, allowing it to sink. The water inlet / outlet system is a system that introduces liquid or gas into the ballast tanks 11 (i.e., discharges liquid). Generally, water, such as seawater, is used. Therefore, the water inlet / outlet system can control the weight of the pontoon 1 (while keeping its volume constant), and the buoyancy of the pontoon 1 can gradually sink the supported aquaculture platform 2 from the water surface to below the water surface, thus achieving launching. The support pier 3 is a supporting component. Generally, the surface of the pontoon 1 is relatively regular, making it easy to place the support pier 3. However, the aquaculture platform 2 is composed of several steel pipes that are cross-connected and fixed, and its surface has a large number of hollow structures, making it difficult to directly support it with airbags 4. In this embodiment, the structure of the support pier 3 can effectively support the aquaculture platform 2 above the pontoon 1. Airbag 4 is a tool commonly used for launching ships. Its principle is that when the airbag 4 is not inflated, it is flat, and when inflated, it becomes cylindrical and can roll. After the airbags 4 are arranged in rows at the bottom of the pontoon 1, after the aquaculture platform 2 is built, the airbags 4 can be inflated to make them roll, which helps the pontoon 1 and the aquaculture platform 2 as a whole to be transferred from land to water.

[0025] Considering that the bottom of the pipe-frame aquaculture platform 2 is composed of large-diameter steel pipes, directly laying airbags 4 at the bottom of the aquaculture platform will face the following technical challenges: (1) The contact area between the bottom frame tube 201 of the breeding platform 2 and the airbag 4 is small, resulting in insufficient load-bearing capacity of the airbag 4; (2) The bottom frame tube 201 structure causes the two ends of the airbag 4 to tend to tilt upwards, reducing the contact area between the airbag 4 and the ground; and the direction of movement is prone to deviation.

[0026] (3) The fishing net is suspended on the side of the bottom frame tube 201. The rolling of the airbag 4 may cause the fishing net to break.

[0027] To solve the above problems, this embodiment provides a deep-sea aquaculture platform launching and lifting device, which achieves the following effects: (1) The upper part of the floating box 1 is equipped with a support 3 to support the aquaculture platform 2. The bottom is flatter, or the bottom can be designed as a plane to increase its contact area with the airbag.

[0028] (2) Floating box 1, with ballast tank 11 inside. After being launched, water can be injected into the ballast tank 11 to make the floating box sink and thus separate from the aquaculture platform.

[0029] (3) After the pontoon 1 is separated from the aquaculture platform 2, the ballast water can be discharged by compressed air, allowing the pontoon to float freely and be effectively recycled.

[0030] In this embodiment, the deep-sea aquaculture platform launching and lifting device involves placing a pontoon 1 at the bottom of the aquaculture platform 2 during its construction on the slipway. Supports 3 positioned between the pontoon 1 and the platform effectively limit the bottom frame tube 201 of the platform 2. An airbag 4 is placed at the bottom of the pontoon 1. Utilizing the characteristic that the inflated airbag 4 forms a rolling cylinder, the pontoon 1 lifts the aquaculture platform 2 for launching. This deep-sea aquaculture platform launching and lifting device facilitates the smooth launching of aquaculture platforms 2 built on land, without relying on a dry dock, and provides convenience for launching large deep-sea aquaculture platforms. The pontoon 1 can be detached and recovered after the aquaculture platform 2 is completed, demonstrating high feasibility.

[0031] Preferably, the deep-sea aquaculture platform launching and lifting device of this embodiment, such as... Figure 3 As shown, the float 1 includes: Inlet and outlet ports 12 are provided for each of the ballast tanks 11 and are located at the bottom of the pontoon 1; Inlet and outlet valve 14, used to open or close the inlet and outlet 12; Air inlets and outlets 13 are provided for each of the ballast tanks 11 and are located on top of the floats 1; The exhaust pipe valve 15 is used to open or close the inlet and outlet ports 13.

[0032] The inlet / outlet 12 is located at the bottom of the pontoon 1 because air is less dense than water. Therefore, when air rushes into the ballast tank 11, it accumulates at the top, allowing water to drain preferentially from the bottom of the pontoon 1. Conversely, the outlet / vent 13 is located at the top of the pontoon 1 to facilitate air venting. The inlet / outlet valve 14 and the vent valve 15 facilitate the control of opening and closing the inlet / outlet 12 and vent 13, respectively. By selectively opening the corresponding valves, the water intake / outlet system of this embodiment can stably control the intake or drainage of water into the ballast tank 11, thereby ensuring stable control of the pontoon 1's ascent or descent.

[0033] Preferably, the deep-sea aquaculture platform launching and lifting device of this embodiment, such as... Figure 3 As shown, the water inlet and drainage system includes: Extension rod bracket 61 is fixed to the side wall of the float box 1; A valve extension rod 62 is movably mounted on the extension rod bracket 61. The valve extension rod 62 corresponds one-to-one with the inlet and outlet pipe valves 14. One end of the valve extension rod 62 is connected to the inlet and outlet pipe valve 14, and the other end is operated from a position away from the inlet and outlet pipe valve 14 to open or close the inlet and outlet pipe valve 14.

[0034] The extension rod bracket 61 can be fixed to one side of the float 1 by welding or bolting. The valve extension rod 62 has a certain degree of freedom, so that when one end rotates or moves, it can drive the other end to rotate or move. For example, when the inlet and outlet valve 14 is flanged, the valve extension rod 62 rotates to drive the flange to open or close the inlet and outlet valve 14. Since it is difficult to operate the inlet and outlet valve 14 after the float 1 is submerged in water, the valve extension rod 62 can be remotely operated. Figure 3 As shown, the upper end of the valve extension rod 62 extends above the water surface to facilitate operation by the operator. After the operator opens the drain pipe valve 14 by operating the upper end of the valve extension rod 62, water from the outside of the float 1 will flow into the ballast tank 11 of the float 1 from the inlet / outlet 12. In this embodiment, the float 1 has several ballast tanks 11, each of which is correspondingly equipped with an inlet / outlet 12, an inlet / outlet valve 14, an air inlet / outlet 13, an air outlet valve 15, an extension rod bracket 61, and a valve extension rod 62. It is understood that when filling multiple ballast tanks 11 with water, the operator needs to open the corresponding number of inlet / outlet valves 14.

[0035] Preferably, the deep-sea aquaculture platform launching and lifting device of this embodiment, such as... Figure 3 As shown, the water inlet and drainage system includes: An exhaust hose 51, one end of which is connected to the inlet / outlet port 13 to allow gas from the ballast tank 11 to be discharged. The float 52 is fixed to the other end of the exhaust hose 51; The air inlet pipe 53 is connected to the ballast tank 11 to introduce gas into the ballast tank 11.

[0036] In this design, the exhaust hose 51 serves to expel gas from the ballast tank 11 and prevents water from flowing back into the ballast tank 11 through the air inlet / outlet 13. The float 52 ensures that one end of the exhaust hose 51 is above the water surface, preventing water from entering the ballast tank 11 and facilitating smooth drainage. The hose design allows for free bending, preventing the stress from being transferred to the connection point with the air inlet / outlet 13, thus avoiding damage or leakage. The air inlet pipe 53 is used to ventilate the corresponding ballast tank 11, such as... Figure 3 As shown, to save the cost of adding an air intake, the air intake position of the air intake pipe 53 reuses the air intake and exhaust ports 13. Specifically, as... Figure 3As shown, in this embodiment, a pipe of a certain length is provided at the inlet / outlet 13. The upper end of the pipe is connected to the exhaust pipe valve 15, and the side of the pipe is connected to the intake pipe 53. Therefore, when the exhaust pipe valve 15 is closed, the gas introduced from the intake pipe 53 can enter the ballast tank 11 through the inlet / outlet 13. An independent intake valve 531 can also be provided on the intake pipe 53 to control the opening or closing of the intake pipe 53 individually. For example, the intake valve 531 can be closed when the intake pipe 53 is not needed. It is understood that since the float 1 in this embodiment has several ballast tanks 11, the exhaust hose 51, float 52, and intake pipe 53 can be provided in several corresponding configurations.

[0037] Preferably, the deep-sea aquaculture platform launching and lifting device of this embodiment, such as... Figure 3 As shown, the water intake and drainage system also includes a workboat 7 and an air compressor 8. The air compressor 8 is located on the workboat 7 and supplies gas to the ballast tank 11 through the air intake pipe 53. One end of the valve extension rod 62 is connected to the water intake and drainage pipe valve 14, and the other end is located on one side of the workboat 7.

[0038] In this scheme, to increase the operability of the deep-sea aquaculture platform launching and lifting device after its launch, a dedicated workboat 7 and an air compressor 8 are provided. The air compressor 8 is used to supply air to the corresponding ballast tank 11 through the air intake pipe 53 to drain water. The workboat 7 is used to transport the air compressor 8 to a position closer to the pontoon 1 for easy operation or observation by the operators. Simultaneously, the workboat 7 also facilitates the operation of the valve extension rod 62 by the operators.

[0039] Preferably, the deep-sea aquaculture platform launching and lifting device of this embodiment, such as... Figure 4 As shown, there are two pontoons 1, which are respectively arranged on both sides of the aquaculture platform 2 and are fixed together by a transverse reinforcing beam 101.

[0040] In this scheme, two floating boxes 1 are arranged, so that a smaller area of ​​floating box 1 can support a larger area of ​​aquaculture platform 2. Generally, to increase the balance of support, the two floating boxes 1 are arranged on both sides of aquaculture platform 2. Figure 4 As shown, the float 1 can be elongated to facilitate the row-by-row support of the airbags 4 at the bottom. It is understood that, without considering cost, the number of floats 1 can be three, four, or more, and multiple floats 1 can be fixed together using the aforementioned transverse reinforcing beams 101. It is also understood that only one float 1 can be provided; when only one float 1 is provided, it should be centrally located at the bottom of the aquaculture platform 2. In this embodiment, the number of transverse reinforcing beams 101 is three, evenly distributed; it is understood that two, one, or four or more beams can also be provided.

[0041] Preferably, the deep-sea aquaculture platform launching and lifting device of this embodiment, such as... Figure 2 , Figure 5 As shown, the deep-sea aquaculture platform launching and lifting device also includes several reinforcing structures 9, the reinforcing structures 9 including: The first support tube 91, the lower end of which is fixed to the upper surface of the float box 1; Second support tube 92; the two ends of the second support tube 92 are respectively fixed to the upper surface of the float box 1 and the first support tube 91, so that the first support tube 91 is fixed. A pad 93 is fixed on the side of the first support tube 91 away from the second support tube 92, and the pad 93 is used to abut against one side of the frame tube 201.

[0042] In this design, the first support pipe 91, the second support pipe 92, and the upper surface of the float 1 form a triangular structure, which has strong stability and can stably support the frame pipe body 201. Figure 5 As shown, to balance the supporting forces on both sides of the frame tube 201, a pair of first support tubes 91 and second support tubes 92 can be respectively set on both sides of one frame tube 201. Alternatively, a first support tube 91 and a second support tube 92 can be set on the left side of one frame tube 201, and a first support tube 91 and a second support tube 92 can be set on the right side of another parallel frame tube 201, that is, to balance the supporting forces on the entire aquaculture platform 2. The pad block 93 can be made of wood, which is low in cost and has low hardness, making it suitable as an object that directly contacts the frame tube 201.

[0043] Preferably, the deep-sea aquaculture platform launching and lifting device of this embodiment, such as... Figure 3 As shown, the pontoon 1 includes: a pontoon body, a transverse bulkhead, and a longitudinal bulkhead 102; the transverse bulkhead and the longitudinal bulkhead 102 divide the pontoon body into several evenly distributed, mutually independent ballast tanks 11.

[0044] In this design, the structure of the pontoon 1 is first constructed by manufacturing a single hollow box, typically designed as a cuboid for ease of manufacturing. Then, transverse and longitudinal bulkheads 102 divide the hollow portion of the box into several independent ballast tanks 11. This design reduces the difficulty and cost of manufacturing the pontoon 1. For example, in this embodiment, the pontoon 1 is a longitudinal frame structure with longitudinal angle steel internally reinforced and T-shaped profiles laterally. Two longitudinal bulkheads 102 divide the interior into three compartments: left, middle, and right. The middle ballast tank 11 is reinforced with three columns 103 as a load-bearing deck. The pontoon 1 is divided into seven independent ballast tanks 11 by transverse bulkheads, each with its own independent inlet / outlet 12 and outlet / vent 13.

[0045] Preferably, the deep-sea aquaculture platform launching and lifting device of this embodiment, such as... Figure 6 As shown, the top of the support 3 is an inwardly concave arc shape, and a rubber pad 31 is provided on the top of the support 3. In this design, the arc shape can fit well with the frame tube 201 of the aquaculture platform 2, which can prevent the aquaculture platform 2 from shifting laterally relative to the floating box 1. The rubber pad 31 increases the friction to improve the stability of the support for the frame tube 201, and at the same time, it can prevent friction damage to the surface metal or paint of the frame tube 201.

[0046] This embodiment provides a method for launching a deep-sea aquaculture platform, using the aforementioned deep-sea aquaculture platform launching and lifting device, including the following steps: Before the aquaculture platform 2 is constructed, the floating box 1 is installed, and the airbag 4 after degassing is installed at the bottom of the floating box 1; During the construction of the aquaculture platform 2, the aquaculture platform 2 is fixed to the upper part of the floating box 1 by a number of the aforementioned support blocks 3; After the aquaculture platform 2 is constructed, the airbag 4 is inflated to allow the float box 1 to lift the aquaculture platform 2 for launching into the water; After the aquaculture platform 2 is launched, liquid is introduced into the ballast tank 11 through the water inlet and outlet system to make the float 1 sink and separate the float 1 from the aquaculture platform 2. After the pontoon 1 detaches from the aquaculture platform 2, gas is introduced into the ballast tank 11 through the water inlet and outlet system to make the pontoon 1 float up and recover the pontoon 1.

[0047] In this embodiment, the liquid introduced into the ballast tank 11 by the water inlet and outlet system is generally sourced directly from nearby seawater, which offers greater feasibility. In the deep-sea aquaculture platform launching and lifting device of this embodiment, after the aquaculture platform 2 is launched, the buoyancy of the float 1 is greater than its own weight plus the weight of the aquaculture platform 2, causing the float 1 to lift the aquaculture platform 2 and float on the water surface. It is understood that, to prevent the float 1 from interfering with the aquaculture platform 2 when it rises, before introducing gas into the ballast tank 11, the float 1 or the aquaculture platform 2 should be moved laterally to offset them in the vertical direction. Alternatively, the lateral traction of the float 1 or the aquaculture platform 2 can be performed simultaneously with the introduction of gas into the ballast tank 11.

[0048] Preferably, in the deep-sea aquaculture platform launching method of this embodiment, after the aquaculture platform 2 is launched, the inlet and outlet pipe valves 14 are opened through the valve extension rod 62. At this time, the inlet and outlet pipe valves 14 are in the open state, water enters each ballast tank 11, the float 1 sinks, and separates from the aquaculture platform 2. During the separation process, the opening and closing of the outlet pipe valves 14 of each independent ballast tank 11 are adjusted to ensure that the water inflow of each tank is consistent, so that the float 1 remains balanced.

[0049] After the pontoon 1 detaches from the aquaculture platform 2, it is raised. The diver closes the exhaust valve 15, connects the air inlet pipe 53, opens the air inlet valve 531 and the inlet / outlet valve 14, and the air compressor 8 on the workboat 7 inflates each independent ballast tank 11 and drains water from the inlet / outlet 12, so that the pontoon 1 floats to the surface.

[0050] The air intake volume and opening / closing of each independent ballast tank 11 can be adjusted by the air intake valve 531, which can also adjust the water intake volume of each independent ballast tank 11 to keep the float 1 in balance.

[0051] Based on the above-described preferred embodiments according to this application, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application. The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
