Description

Technical Field

[0001] This invention belongs to the field of pipeline systems and mechanical engineering technology, and more specifically, it relates to an integrated device for moving and fixing an arched submarine hose. Background Technology

[0002] With the dwindling reserves of terrestrial fossil fuels, marine resources have gradually become an important direction for energy development in various countries. However, the development and transportation of seabed fossil fuels still face many technical challenges, especially in the transportation stage in complex marine environments. Flexible hoses, due to their flexibility and adaptability, have become the main method for seabed oil and gas transportation. However, under the influence of multiple factors such as waves, ocean currents, and water depth, hoses are prone to positional drift and structural instability, seriously affecting transportation safety and efficiency. Therefore, developing a structural device that can achieve precise positioning, effective support, and stable fixation of hoses has become a key problem urgently needing to be solved in the field of seabed energy engineering. Arch-bridge type fixing devices, with their structural stability, flexible positioning, and good support performance, provide a reliable technical path and engineering guarantee for the stable transportation of hoses in the seabed environment.

[0003] The fixing seat in an arch-bridge type fixing device generally consists of an arched support surface, two side wall fixing surfaces, and a fixing connection part. It can also be modified according to the actual needs of the hose in the project. During the development and utilization of subsea oil and gas resources, the hose obtains necessary support and constraint through contact with the concave seat support surface. However, under actual stress conditions, it may still sway or slip due to factors such as ocean current impact or topographic changes, thus adversely affecting the stability of transportation. Therefore, the structural design of the fixing seat must not only meet the basic load-bearing function but also fully consider the complexity of the seabed environment and dynamic load conditions to achieve more stable and reliable positioning and support for the hose, thereby improving the safety and operational efficiency of the overall transportation system.

[0004] Currently, traditional mounting brackets have the following problems in practical applications: ① While traditional fixed bases can provide basic support in practical applications, under the influence of dynamic marine environments such as wind, waves, and currents, the hoses are prone to swaying and displacement, making it difficult to maintain a stable position. In fact, frequent contact with the base can cause impacts, resulting in structural wear and damage.

[0005] ② In marine oil and gas transportation environments, traditional cast iron mounting brackets are prone to oxidation and corrosion when exposed to seawater for extended periods. Not only is surface corrosion significant, but internal structural damage such as cracks may also occur due to alternating hot and cold temperatures. Cast iron is also susceptible to localized breakage, detachment, or deformation due to long-term pressure, thereby reducing its load-bearing capacity and affecting its service life and safety.

[0006] ③ When installing or adjusting the position of a traditional fixed base, the hose movement is quite laborious due to its high coefficient of friction. This not only results in low operating efficiency but may also cause varying degrees of mechanical wear or damage to the hose body and base structure.

[0007] ④ When a traditional fixed seat is used in conjunction with a winch, and multiple hoses need to be supported at the same time, the winch must provide greater traction to maintain the overall stability of the fixed seat. This not only increases the difficulty of operation, but may also bring additional structural stress load.

[0008] ⑤ The mounting bracket lacks intelligent monitoring capabilities, making it impossible to perceive and provide feedback on its stress state, positional deviation, and contact state with the hose in real time. This makes it difficult to detect and take emergency measures in a timely manner if structural abnormalities or hose misalignment occur. Summary of the Invention

[0009] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention provides an integrated device for moving and fixing submarine hoses with an arched structure, which is designed to adapt to the flexible deployment and precise positioning of hoses in various practical application environments, achieve stable fixing under complex water flow or vibration conditions, effectively reduce the impact of external disturbances on the hose and device body, prevent the hose from being damaged or falling off due to continuous vibration, and improve the corrosion resistance of the fixing device body to meet the requirements of long-term marine service.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: an integrated device for moving and fixing an arched subsea hose, comprising: a hose seat, which is an arched tubular structure with a hose channel formed inside for the hose to pass through, thereby constraining the vertical and horizontal displacement of the hose; hose support pulleys, wherein a plurality of hose support pulleys are disposed within the hose channel of the hose seat for supporting and driving the hose to move; a hose anti-displacement mechanism, wherein two hose anti-displacement mechanisms are respectively disposed at the two ends of the hose seat for constraining the movement of the hose when it has a large directional displacement; and a seat locking mechanism, connected between the guide frame and the hose seat to lock the hose seat at a specified height on the guide frame.

[0011] Preferably, the hose seat includes an upper convex seat, a lower concave seat, and side wall seats located on both sides of the two, which together form the hose channel.

[0012] Preferably, the concave seat and the side wall seat are arched, and a plurality of hose support pulleys are evenly installed in the upper convex seat according to the arch, with the hose passing around each hose support pulley; the upper convex seat is arc-shaped, with three sections of the upper convex seat covering the upper part of the hose to constrain the vertical displacement of the hose, and there is a gap between adjacent sections of the upper convex seat; the two side wall seats are located on both sides of the hose to constrain the horizontal displacement of the hose.

[0013] Preferably, a rubber shock absorber is provided between the concave seat and the hose. The upper side of the rubber shock absorber is fixed to the inner wall of the concave seat, the two sides of the rubber shock absorber are fixed to the two side wall seats, and the lower side of the rubber shock absorber is in contact with the outer wall of the hose.

[0014] Preferably, a hose locking clamp is installed at two gaps in the three sections of the concave seat. The hose locking clamp is connected to the concave seat via a connecting rod and can be vertically displaced along a guide rail provided in the concave seat. When the hose moves to the expected position, the hose locking clamp is adapted to lock the hose to constrain the vertical displacement of the hose in the gap.

[0015] Preferably, the system also includes a pulley assembly, which includes a movable pulley, a movable pulley connecting rod, and fixed posts. The two fixed posts are symmetrically fixed on the two side wall seats. One end of each of the two movable pulley connecting rods is fixed to the two fixed posts, and the other end of each movable pulley connecting rod is rigidly connected to the movable pulley. The winch rope is wound around the movable pulley.

[0016] Preferably, an environmental monitoring unit is installed in two gaps located in the three concave sections of the seat. The environmental monitoring unit includes an integrated sensor for flow velocity and depth, as well as an integrated sensor for pressure and leakage alarm, for real-time acquisition of the depth, pressure and ocean current velocity of the environment in which the hose is located.

[0017] Preferably, the hose anti-displacement mechanism includes a flared anti-displacement sleeve and a connector. The anti-displacement sleeve is fixedly connected to the end of the hose seat through the connector. The outer wall of the anti-displacement sleeve can effectively buffer the impact load of waves on the hose, while the inner wall of the anti-displacement sleeve can constrain the displacement amplitude of the hose in all directions.

[0018] Preferably, the seat locking mechanism includes a "C"-shaped catheter holder locking clamp and a support rod perpendicular to the catheter holder locking clamp and connecting the two into one piece. One end of the support rod is fixedly connected to one side of the concave seat, and the other end of the support rod is fixedly connected to the catheter holder locking clamp. The catheter holder locking clamp is adapted to lock at a specified height of the catheter holder.

[0019] Preferably, the convex upper seat, the concave lower seat, and the side wall seat are all made of stainless steel.

[0020] The present invention has the following advantages due to the adoption of the above technical solutions: 1. The integrated subsea hose movement and fixing device of the present invention is designed with a spatial structure resembling an arch bridge. It not only possesses excellent mechanical properties but also high stability and adaptability, effectively undertaking load distribution and structural constraint tasks in various complex environments. Its main function is as a support and fixing device for precise positioning, stable support, and spatial limitation control of key components. It is particularly suitable for the stabilization structure of underwater pipeline systems, support systems in land facilities, and the mechanical stability assurance of bridges or truss structures in transportation infrastructure. Due to its superior force transmission path and structural stiffness, this structural form is widely used in scenarios such as pipeline laying, temporary or permanent structural reinforcement, subsea equipment fixing, and bridge auxiliary support, and is an indispensable key structural unit in many engineering fields.

[0021] 2. When the hose support pulley provided by the present invention comes into contact with the hose, it can effectively reduce the frictional resistance during the relative movement of the hose, making the hose move more smoothly and avoiding wear of the hose structure due to excessive friction, thereby improving the service life of the hose and optimizing the overall operating efficiency. It can also provide some support for the hose.

[0022] 3. In the pulley assembly provided by the present invention, the movable pulley is connected to the winch rope on the winch and the fixed rod welded to the entire device. By using the movable pulley, the tension of the winch rope can be reduced, thereby reducing the power output of the winch on the platform.

[0023] 4. The hose base and various sensing and measuring devices provided by this invention are all made of stainless steel with excellent resistance to damp heat corrosion. They can effectively resist the corrosion and erosion caused by long-term high salt and high humidity conditions in the marine environment, prevent the degradation of mechanical properties caused by material corrosion, and thus ensure the structural integrity and operational safety of the device during its service life.

[0024] 5. The locking clamps provided by this invention are distributed in three locations. The first location is installed on one side of the concave base. After the hose and the entire device have moved to the expected height, the hose locking clamp will fix itself to the nearest hose support. The other two locations are distributed in the gaps of the concave base. When the hose moves to the expected position, the hose locking clamp will lock the hose in a fixed position, effectively preventing the hose from slipping or colliding with the base under dynamic loads such as ocean wind, waves, and currents, ensuring that the continuous and stable delivery of the medium inside the hose is not disturbed.

[0025] 6. The present invention has an environmental monitoring unit installed in two gaps in the three-section concave base, which can realize real-time perception and data transmission of the external environmental parameters of the hose, providing basic support for subsequent data analysis, structural response judgment and risk warning, thereby improving the intelligent monitoring capability and safety assurance level of the entire device.

[0026] 7. The horn-shaped hose anti-displacement mechanism provided by the present invention can effectively prevent the hose from being displaced too much in all directions under the action of ocean wind, waves and currents, which would cause hose deformation, thereby affecting hose leakage, damage and service life.

[0027] In summary, through optimized mechanical structure and material selection, this invention can effectively adapt to the actual working conditions of submarine hoses during movement and fixation, significantly improving the operating efficiency, safety and service life of the hose delivery system, and is especially suitable for long-term operations in harsh marine environments.
