The invention provides a submarine pipeline protection device for preventing anchor damage, and specifically relates to the technical field of submarine pipelines. The present invention comprises a submarine pipeline. A bottom plate is provided on the underside of the submarine pipeline, and a set of fixed rods is arranged on the bottom plate. The fixed rod groups are respectively arranged on both sides of the submarine pipeline; device, the first buffer device and the second buffer device are hinged with the fixed rod group, and a torsion spring is arranged between the fixed rod group and the first buffer device and between the second buffer device; a connecting rod is arranged above the submarine pipeline to connect The rod passes through the first buffer device and the second buffer device; the first buffer device and the second buffer device are respectively provided with a first slide hole and a second slide hole, and the connecting rod is respectively slidably connected with the first slide hole and the second slide hole. The invention provides a submarine pipeline protection device for preventing anchor damage, which can prevent the submarine pipeline from being damaged, and prevent objects in the submarine pipeline from flowing into the sea, causing economic losses.
Description
technical field [0001] The invention belongs to the technical field of submarine pipelines, in particular to a submarine pipeline protection device for preventing anchor damage. Background technique [0002] Submarine pipelines are composed of steel pipes, insulation layers, counterweight layers, heating systems, and anti-corrosion systems to transport oil, gas, and chemical agents, and are used to connect platforms, single points, and onshore oil depots. [0003] A structural member for protecting submarine pipelines (authorization number CN201720567203.8), discloses a structural member for protecting submarine pipelines. The device includes a supporting part and a crossbeam, so that the structural parts protecting the submarine pipeline are easy to install and the construction is convenient, but the protection effect of the device on the submarine pipeline is not good, and it is easy to be damaged by ship anchors. [0004] In view of the above situation, there is a need f...
