[0002] As an important basic structure, suction anchors are widely used for fixing offshore platforms, floating wind power devices, etc. Suction anchors penetrate the seabed soil layer through negative pressure and rely on the friction and adsorption forces between themselves and the soil layer to provide a stable anchoring effect.
[0003] Traditional suction anchor negative pressure penetration devices have poor sealing performance at the connection points when connecting to the suction anchor. During the drainage and venting process, gas or liquid leakage is prone to occur. This not only prevents the negative pressure from being effectively established, affecting the penetration effect of the suction anchor, but also causes a certain degree of pollution to the surrounding marine environment. At the same time, the connection structure is not stable enough, and the connection between the air tube and the suction anchor is prone to loosening under the erosion of the external environment, which may even cause it to fall off in severe cases.
[0004] To solve the above technical problems, it is necessary to design a shared suction anchor negative pressure penetration device. Utility Model Content

Detailed Implementation
[0017] Please see Figures 1-4 The shared suction anchor negative pressure penetration device includes a suction anchor body 1, a conveying pipe 2 connected to the top of the suction anchor body 1, a connecting sleeve 3 threaded onto the top of the conveying pipe 2, a sealing ring 4 between the conveying pipe 2 and the connecting sleeve 3, a connecting pipe 5 connected to the top of the connecting sleeve 3, a long pipe 6 connected to the top of the connecting pipe 5, a movable pipe 7 movably fitted onto the surface of the connecting sleeve 3, L-shaped plates 8 fixedly connected to both sides of the movable pipe 7, a cylinder 9 penetrating the surface of the L-shaped plate 8, and a clamping ring 10 fixedly connected to one side of the cylinder 9. The sealing ring 4 between the conveying pipe 2 and the connecting sleeve 3 effectively prevents gas or liquid from entering during the drainage and exhaust process. The system ensures stable operation of the negative pressure system, whether in normal operation or under the influence of complex marine environmental factors. This provides a reliable guarantee for the smooth penetration of the suction anchor into the seabed soil layer and avoids the problem of insufficient negative pressure caused by leakage. It greatly improves the success rate and efficiency of construction. Through the coordinated action of the movable pipe 7, L-shaped plate 8 and cylinder 9, cylinder 9 drives clamping ring 10 to tightly clamp the connecting pipe 5, making the connection between the connecting sleeve 3 and the connecting pipe 5 more firm and reliable. Even under the repeated action of external forces such as ocean currents and waves, it can effectively prevent the connection from loosening or falling off, ensuring the continuity and stability of the negative pressure penetration process.
[0018] Please see Figures 1-3 The side of the clamping ring 10 away from the cylinder 9 contacts the delivery pipe 2. The surface of the cylinder 9 is connected to the air inlet pipe 11. When the cylinder 9 applies force to the connecting pipe 5 through the clamping ring 10, it can better transmit and disperse the force, enhance the connection stability between the connecting sleeve 3 and the connecting pipe 5, and adapt to more complex marine operating environments. By setting the air inlet pipe 11, a stable air supply channel is provided for the cylinder 9, which facilitates precise control of the cylinder 9's movement through an external air source, and realizes flexible adjustment of the clamping force of the clamping ring 10, meeting the requirements for connection stability under different construction conditions.
[0019] Please see Figures 1-3 The bottom of the sealing ring 4 contacts the conveying pipe 2, and the top of the sealing ring 4 contacts the inner wall of the connecting sleeve 3. A fixing ring 12 is fixedly sleeved on the surface of the conveying pipe 2. The bottom of the connecting sleeve 3 contacts the fixing ring 12, and the bottom of the fixing ring 12 contacts the clamping ring 10. By setting the sealing ring 4, an all-round seal is formed, which effectively prevents gas or liquid from leaking from the gap at the connection between the conveying pipe 2 and the connecting sleeve 3, thereby improving the sealing performance. By setting the fixing ring 12, the bottom of the connecting sleeve 3 is supported and the top of the clamping ring 10 is limited, thereby improving the stability of the connection between the connecting sleeve 3 and the conveying pipe 2.
[0020] Please see Figures 1-4The end of the long pipe 6 away from the connecting pipe 5 is connected to a filter box 13. The right side of the filter box 13 is connected to a discharge pipe 14. The inner cavity of the filter box 13 is equipped with a filter frame 15. By setting the filter frame 15, the gas or liquid discharged from the suction anchor 1 through the long pipe 6 can be filtered and treated, and impurities, particles and other pollutants can be intercepted, so that the discharged substances are purified and pollution to the marine environment is reduced.
[0021] Please see Figures 1-4 The front side of the filter frame 15 extends to the outside of the filter box 13 and is fixedly connected to a sealing plate 16. A bolt 17 is connected through the surface of the sealing plate 16. The bolt 17 passes through the sealing plate 16 and is threadedly connected to the filter box 13. By setting the sealing plate 16 and the bolt 17, the installation and removal of the filter frame 15 becomes simple and quick. When it is necessary to clean or replace the filter frame 15, simply unscrew the bolt 17 to remove the filter frame 15 from the filter box 13, which greatly improves maintenance efficiency.
[0022] Please see Figures 1-2 A sealing gasket 18 is bonded to the rear side of the sealing plate 16. The rear side of the sealing gasket 18 contacts the filter box 13. By setting the sealing gasket 18, the sealing performance between the sealing plate 16 and the filter box 13 is further enhanced. The soft material of the sealing gasket 18 can better fill the tiny gaps between the contact surfaces of the sealing plate 16 and the filter box 13, effectively preventing gas or liquid leakage and ensuring that the filter box 13 is in a good sealed state during the filtration process.
[0023] Please see Figures 1-4 The top and bottom of the inner wall of the filter box 13 are fixedly connected with pads 19. The left side of the pads 19 contacts the filter frame 15. The top of the filter box 13 is connected to a pressure gauge 20. By setting the pads 19, a stable support is provided for the filter frame 15, which can prevent the filter frame 15 from shaking or shifting due to the impact of gas or liquid during the filtration process, and ensure the filtration effect and stability of the filter frame 15.
[0024] In use, the connecting sleeve 3 is threadedly connected to the conveying pipe 2, causing the connecting sleeve 3 to move downwards. The top of the connecting pipe 5 presses against the sealing ring 4. The air inlet pipe 11 is connected to an external air pump, which delivers gas into the inner cavity of the cylinder 9. The cylinder 9 extends, causing the clamping ring 10 to move. The clamping ring 10 clamps the conveying pipe 2, fixing the connecting sleeve 3. The discharge pipe 14 is connected to an external negative pressure suction device, which absorbs the gas or liquid inside the suction anchor 1. The gas and liquid inside the suction anchor 1 pass through the conveying pipe 2, connecting sleeve 3, connecting pipe 5, and long pipe 6 in sequence, and enter the inner cavity of the filter box 13. The filter frame 15 filters out impurities and particles in the gas or liquid, and finally discharges through the discharge pipe 14. The pressure gauge 20 detects the pressure inside the filter box 13 to determine the pressure inside the suction anchor 1. The bolt 17 is removed with a tool, and the sealing plate 16 is moved to move the filter frame 15. The filter frame 15 is then disassembled, and impurities inside the filter frame 15 are cleaned.
[0025] In summary, this shared suction anchor negative pressure penetration device, through the delivery pipe 2, connecting sleeve 3, sealing ring 4, connecting pipe 5, long pipe 6, movable pipe 7, L-shaped plate 8, cylinder 9, and clamping ring 10, solves the problems of poor sealing performance, easy gas or liquid leakage, poor connection stability, and easy loosening of the connection between the air pipe and the suction anchor under the corrosive influence of the external environment in traditional suction anchor negative pressure penetration devices.
