Description

Technical Field

[0001] This utility model relates to the field of seabed rock-throwing technology, and in particular to a deep-sea seabed rock-throwing telescopic guide tube device. Background Technology

[0002] A deep-sea subsea rock-drop telescopic duct device is a marine engineering equipment used for subsea rock-drop operations. During the laying and use of subsea pipelines, damage is often caused by factors such as uneven seabed, unstable geology, and external impacts. Underwater rock-drop is an effective, economical, and feasible solution to protect the stability and safety of subsea pipelines. This device was developed to achieve more efficient and safer deep-sea rock-drop operations. It uses a telescopic sleeve to transport crushed stones. The contraction and extension of the telescopic sleeve can be controlled by a telescopic traction mechanism according to the location of the subsea pipeline and construction requirements. Before construction, all rock-drop pipes are evenly placed on the installation platform. After the construction vessel is in position, the first rock-drop pipe is lifted using the lifting equipment on the installation platform. The lifting point is set at the flange position at the end of the rock-drop pipe. During the lifting process, the rock-drop pipe is in a vertical state, and the lower end of the rock-drop pipe falls onto the top of the rock-drop ROV, aligning the lower flange of the rock-drop pipe with the top flange of the rock-drop ROV, and is fixed with special reinforcing bolts.

[0003] In the event of strong winds or other severe weather, the retractable telescopic sleeve can be folded to the side of the hull using the folding towing mechanism to quickly avoid wind damage and ensure the safety of construction personnel and equipment. When not in operation, the telescopic rails can be folded and stored, reducing the space occupied by the device on the ship and allowing the ship to move and turn more flexibly. This facilitates quick access to the construction site or other operations, thereby improving overall work efficiency. Folding and storing the telescopic rails also provides better protection when not in use, reducing the erosion and wear caused by seawater, sea winds, and other natural factors, extending the service life of the equipment, and reducing maintenance and replacement costs.

[0004] In existing technologies, when ships dock at ports for resupply, repair, or transshipment, the extended telescopic guide rails increase the overall size of the ship, making docking difficult and requiring more space. During transport, this also increases the risk of collisions with other objects, causing inconvenience to navigation and docking. In severe weather conditions such as strong winds, heavy rains, and high waves, the telescopic guide rails, which are difficult to fold and store, are exposed and more susceptible to impact and damage from wind and waves. Strong winds can cause the guide rails to shake violently or deform, even damaging the connection between the guide rails and the hull, rendering the entire rock-throwing device unusable and increasing equipment maintenance costs and the risk of construction delays. Therefore, a deep-sea seabed rock-throwing telescopic guide pipe device is proposed to solve these problems. Utility Model Content

The fixed blocks 20 provide stability for the connecting rods 17 and prevent swaying or deviation during operation.

[0038] Working principle: When the telescopic guide tube needs to be folded and stored, cylinder 4 inside the square box 2 is activated. Cylinder 4 pushes slider 5 to slide on the top of fixed plate 3. Fixed plate 3 provides limiting and guiding function for slider 5, preventing shaking and deviation during movement. When slider 5 moves, it drives support plate 6 to move. When support plate 6 moves, it drives internal connecting rod 7 to move. Connecting rod 7 drives rear slider 8 to move. Slider 8 has two fixed rods 9 inside. The fixed rods 9 move in the C-shaped groove inside the limiting block 10, driving connecting rod 7 to rotate. When connecting rod 7 rotates, it drives fixed plate 11 at the front end and transmission pipe 12 inside fixed plate 11 to rotate, achieving the folding and storage effect. The folding and storage function makes the device more adaptable to different types and sizes of ships or construction platforms, and allows for flexible installation and disassembly according to actual construction needs, improving the equipment's versatility and applicability.

[0039] When the telescopic conduit needs to be extended or retracted, the second fixing plate 11 is fixed to the front end of the connecting rod 7, providing a supporting foundation for the entire telescopic assembly. The first transmission pipe 12 is fixed inside the second fixing plate 11 to guide material transmission. The first mounting plate 13 is fixed to the outside of the first transmission pipe 12, and multiple first fixing blocks 14 are connected to its bottom end. The second cylinder 15 is rotatably connected to the inside of the first fixing block 14. When the second cylinder 15 is started, its driving end extends or shortens, driving the second fixing block 16 fixed to it to move, thereby causing the connecting rod 17 rotatably connected inside the second fixing block 16 to move. When the connecting rod 17 moves, it pushes the second transmission pipe 18 to slide relative to the first transmission pipe 12, realizing the telescopic function. The second mounting plate 19 is fixed to the outside of the second transmission pipe 18, and the third fixing block 20 at its bottom end further stabilizes the structure. Under the continuous action of the second cylinder 15, the second transmission pipe 18 continuously extends and retracts, thereby flexibly adjusting the length according to actual construction needs to adapt to different rock-throwing operation scenarios.
