Description

Technical Field

[0001] This application belongs to the field of buoyancy aid technology, and more specifically, relates to a buoyancy aid based on water pressure connection. Background Technology

[0002] In the field of marine engineering, buoyancy devices are often used to reduce the weight of large marine engineering components during installation, thereby reducing the load on lifting equipment and improving construction safety. Current technology commonly uses floating bodies to connect to the components, using buoyancy to offset some of the weight. However, this traditional method has significant operational drawbacks. Specifically, the connection structure between the floating body and the component is often complex, requiring multiple fastening procedures during installation, and the underwater working environment makes precise positioning difficult for operators. During disassembly, the connection points are prone to jamming, leading to disassembly difficulties. This not only increases construction time and labor costs but also hinders the improvement of marine engineering construction efficiency. Utility Model Content

[0003] The purpose of this application is to provide a buoyancy aid device based on water pressure connection, so as to solve the technical problem of cumbersome disassembly and assembly process of existing buoyancy aid devices.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] A buoyancy aid device based on hydraulic connection is provided, comprising:

[0006] The float is equipped with a water-stop seal, which is used for a sealed connection with the buoyancy-aiding workpiece; when the float is installed on the buoyancy-aiding workpiece, the float, the water-stop seal, and the buoyancy-aiding workpiece together form a sealed cavity.

[0007] The float is also equipped with a vent valve, which is connected to the sealed cavity. After the air in the sealed cavity is discharged through the vent valve, a negative pressure is formed in the sealed cavity, and the float is pressed against the buoyancy aid by the external water pressure.

[0008] As a further improvement to the above technical solution:

[0009] Optionally, the water-stop seal is located at the bottom of the float and extends circumferentially along the float to effectively increase the sealing contact area and improve sealing reliability.

[0010] Optionally, the float is a float with a cavity, and the buoyancy of the float is less than the external water pressure when the float is pressed against the buoyancy aid workpiece by external water pressure, so that the float can maintain an appropriate upward trend during installation, and can be stably pressed against the surface of the buoyancy aid workpiece under water pressure.

[0011] Optionally, the float is provided with a water valve that communicates with the cavity. Water is injected into or drained into the cavity through the water valve to adjust the buoyancy and gravity of the float, so that the float can dynamically adjust its stress state at different operating stages. When it is necessary to increase the sinking force, water can be injected through the water valve to increase the gravity, and when it is necessary to increase the buoyancy, water can be drained to reduce the gravity.

[0012] Optionally, the base of the float is further provided with reinforcing ribs to enhance the overall rigidity and deformation resistance of the float base.

[0013] Optionally, multiple floats are used, each connected to the buoyancy-aiding workpiece at intervals, ensuring that each float can function independently while avoiding mutual interference. This distributed layout of multiple floats improves the overall system stability by increasing the number of support points, and allows for flexible adjustment of the number and arrangement of floats according to the actual size and weight requirements of the buoyancy-aiding workpiece. When multiple floats work together, they can evenly distribute the load on the buoyancy-aiding workpiece, and by independently controlling the buoyancy state of each float, precise adjustment of the workpiece's attitude can be achieved.

[0014] The beneficial effects of the buoyancy aid device based on water pressure connection provided in this application are as follows:

[0015] This application provides a buoyancy aid device based on water pressure connection, which utilizes the principle of negative pressure to achieve reliable connection and convenient separation between the float and the buoyancy aid workpiece. The device includes a float with a water-stop seal made of elastic sealing material, capable of forming a tight contact with the outer surface of the buoyancy aid workpiece. When the float is installed on the buoyancy aid workpiece, the float, the water-stop seal, and the buoyancy aid workpiece together form a sealed cavity. The float also has a vent valve directly connected to the sealed cavity. During installation, air is gradually expelled from the sealed cavity through the vent valve, creating a negative pressure state inside the cavity. As the negative pressure is established, external water pressure acts on the surface of the float, pushing it towards the buoyancy aid workpiece, thus ensuring a stable connection between the two. This device achieves a sealed fixation between the float and the buoyancy aid workpiece through the synergistic effect of water pressure and negative pressure, and also simplifies the connection structure and operation steps between the float and the buoyancy aid workpiece.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 3 to 5 As shown, this application provides a buoyancy aid device based on water pressure connection. This device utilizes the principle of negative pressure to achieve reliable connection and convenient separation between the float and the buoyancy aid workpiece. The device includes a float 1, on which a water-stop seal 11 is provided. The water-stop seal 11 is made of elastic sealing material and can form a tight contact with the outer surface of the buoyancy aid workpiece 2. When the float 1 is installed on the buoyancy aid workpiece 2, the float 1, the water-stop seal 11, and the buoyancy aid workpiece 2 together form a sealed cavity.

[0035] The float 1 is also equipped with a vent valve 12, which is directly connected to the sealed cavity. During installation, the air inside the sealed cavity is gradually discharged through the vent valve 12, creating a negative pressure state inside the cavity. As the negative pressure is established, external water pressure acts on the surface of the float 1, pushing the float 1 towards the buoyancy aid 2, thereby ensuring a stable connection between the two. This device achieves a sealed fixation between the float 1 and the buoyancy aid 2 through the synergistic effect of water pressure and negative pressure, and also simplifies the connection structure and operation steps of the float 1 and the buoyancy aid 2.

[0036] like Figures 3 to 5 As shown, in a specific embodiment of this application, the water-stopping seal 11 is arranged in a ring structure at the bottom edge of the float 1, and extends continuously along the circumference of the float 1 to form a complete sealing ring.

[0037] The installation position of the water-stop seal 11 must ensure that when the float 1 is connected to the buoyancy aid 2, it can form a circumferentially continuous sealing contact surface with the outer surface of the buoyancy aid 2. This annular arrangement effectively increases the sealing contact area, improves sealing reliability, and facilitates uniform stress distribution during installation. The circumferential extension structure of the water-stop seal 11 allows it to adapt to buoyancy aids 2 of different sizes, enhancing the versatility and adaptability of the device.

[0038] In one specific embodiment of this application, the float 1 adopts a hollow structure with an internal cavity to provide buoyancy.

[0039] The maximum buoyancy provided by the float 1 is less than the water pressure that needs to be overcome when the float 1 is pressed against the buoyancy aid 2 by external water pressure. This allows the float 1 to maintain a proper upward trend during installation, while being stably pressed against the surface of the buoyancy aid 2 under water pressure. The hollow structure of the float 1 not only reduces the overall weight but also ensures the reliability and stability of the installation process by rationally controlling the balance between buoyancy and water pressure.

[0040] like Figures 3 to 5 As shown, in a specific embodiment of this application, the float 1 is provided with a water valve 13, which is in communication with the interior of the cavity.

[0041] By operating the opening and closing state of the water valve 13, water can be selectively injected into or discharged into the cavity, thereby adjusting the ratio of buoyancy to gravity borne by the float 1. This allows the float 1 to dynamically adjust its stress state at different operating stages. When it is necessary to increase the sinking force, water can be injected through the water valve 13 to increase the gravity, and when it is necessary to increase the buoyancy, water can be drained to reduce the gravity.

[0042] like Figures 3 to 5 As shown, in a specific embodiment of this application, the bottom structure of the float 1 is further provided with reinforcing ribs 14.

[0043] The reinforcing ribs 14 are arranged radially or in a grid pattern, extending along the base surface of the float 1 and integrally formed with its structure. The reinforcing ribs 14 effectively enhance the overall rigidity and deformation resistance of the bottom structure of the float 1, enabling it to withstand compressive stress under external water pressure and impact loads during installation. By optimizing the distribution density and cross-sectional dimensions of the reinforcing ribs 14, the structural stability of the float 1 can be significantly improved without significantly increasing its own weight, ensuring the structural integrity of the float 1 in long-term underwater operating environments.

[0044] like Figure 1 and Figure 2 As shown, in a specific embodiment of this application, a plurality of floats 1 are disposed on the buoyancy aid 2, and these floats 1 are evenly distributed at a predetermined interval in the circumferential position of the buoyancy aid 2.

[0045] The various floats 1 are spaced appropriately to ensure that each float 1 can function independently while avoiding mutual interference. This distributed layout of multiple floats 1 improves the overall system stability by increasing the number of support points, and allows for flexible adjustment of the number and arrangement of floats 1 according to the actual size and weight requirements of the buoyancy-aiding workpiece 2. When multiple floats 1 work together, they can evenly distribute the load of the buoyancy-aiding workpiece 2, and by independently controlling the buoyancy state of each float 1, the attitude of the buoyancy-aiding workpiece 2 can be precisely adjusted.

[0046] When using the buoyancy aid device based on water pressure connection provided in this application, a small floating crane is first used to lift the buoyancy aid device to the designed installation position. After the float 1 and the buoyancy aid 2 complete the initial docking and form an initial seal, the vent valve 12 is immediately closed to ensure the airtightness of the sealed cavity. Subsequently, the semi-submersible barge is controlled to submerge. When the submersion depth exceeds 10m above the bottom of the float 1, the vent valve 12 is reopened. At this time, the external water pressure is sufficient to maintain the sealed connection between the float 1 and the buoyancy aid 2, and the water pressure acting on the float 1 has significantly exceeded its own buoyancy.

[0047] The buoyancy aid 2 continues to sink under gravity until it reaches the mud surface and settles under its own weight. After settling, water equal to the buoyancy force is injected into the cavity of the float 1 through the water valve 13, bringing the float 1 to a neutral buoyancy state. Then, the hook of the floating crane is connected to the lifting point of the float 1, and compressed air is injected into the sealed cavity through the air valve 12. The air pressure is used to balance the external water pressure, achieving a smooth separation between the float 1 and the buoyancy aid 2.

[0048] During the lifting process of the floating crane, the water in the cavity of the float 1 is simultaneously discharged through the water valve 13, gradually restoring the buoyancy of the float 1. This device achieves efficient connection and separation of the float 1 and the buoyancy-aiding workpiece 2 by orderly controlling the operation processes of venting, water injection, air filling and drainage. The entire disassembly and assembly process is simple to operate and safe and reliable.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
