Description

Technical Field

[0001] This utility model relates to the field of underwater construction technology, and in particular to a deployment device. Background Technology

[0002] In the field of marine engineering construction, the safety and stability of subsea pipelines are of paramount importance. Concrete manhole covers, a commonly used protective structure, are primarily used to cover and protect near-shore subsea pipelines, preventing damage from external factors such as ship anchoring and trawling operations caused by insufficient burial depth or improper construction. Although relevant departments issue navigation warnings or designate no-anchoring zones before construction, subsea pipeline damage incidents still occur frequently, and tracing responsibility is difficult, resulting in significant economic losses for pipeline operators.

[0003] In existing technologies, the deployment of concrete sluice gates typically involves a construction vessel, guided by navigation equipment, transporting the concrete sluice gates to a designated sea area. A crane then connects the sluice gates to a lifting device, which is used to hang the sluice gates. Multiple sluice gates are then lifted and released one by one along the seabed pipeline laying route, using their own weight to cover the exposed seabed pipelines, thus forming an effective external barrier. However, dedicated lifting equipment is generally lacking in concrete sluice gate deployment operations. Often, temporary steel frames welded on-site are used for lifting, and separating the steel frame from the concrete sluice gates is inconvenient. This results in the concrete sluice gates folding during the lowering process, reducing the original protected area and directly impacting construction quality and efficiency. Utility Model Content

As the actuating rope 5 is pulled, the movable hook 4 can be rotated at a certain angle, preferably from the first position facing upward to the second position facing downward, thereby causing the underwater concrete row 1 to detach from the frame 2 and cover the pipeline on the seabed under its own gravity.

[0037] Furthermore, as a preferred embodiment, the annular suspension member 6 is preferably a wire rope loop or metal ring fixed at the diagonal of the underwater concrete row 1.

[0038] Furthermore, in a preferred embodiment, the movable hook 4 includes a first part 7 and a second part 8.
