Description

Technical Field

[0001] The utility model relates to the technical field of sea sweeping equipment, in particular to a sea sweeping anchor. Background Art

[0002] Before laying submarine cables or submarine pipelines, corresponding sea sweeping operations must be carried out. The purpose of this sea sweeping operation is to remove the remaining obstacles on the seabed so that the laying of submarine pipelines can proceed smoothly. The above-mentioned seabed obstacles generally include fishing nets discarded during fishing operations, residual piles of aquaculture seine nets, wire ropes, anchors, etc.

[0003] At present, sea sweeping operations are generally carried out in the early stage of the project by scanning the laying path of the submarine pipeline through instruments such as side-scan sonar, but this type of equipment can only detect obstacles on the upper surface of the seabed. It is difficult to effectively discover and judge some obstacles that have been abandoned on the seabed for a long time or buried under the seabed. Therefore, the prior art considers further using anchors and the like to conduct in-depth obstacle clearance along the laying path to remove some deeply buried obstacles. Specifically, during the sea sweeping operation, the ship, under the guidance of the navigation equipment, drags the anchor and moves repeatedly along the pipeline laying route, and uses the hook-shaped part of the anchor to cut into the soil under the seabed to hook the corresponding obstacles for removal.

[0004] However, the existing anchors are light in weight, and the position of the hook portion is not stable when it is on the seabed surface or cuts into a certain depth, which often makes it less effective in hooking obstacles. The anchors are also prone to deformation or breakage, and the entire anchor has to be replaced, which is costly and delays the normal progress of the sea sweeping work. In addition, the anchor itself is large in size and is not easy to transport and store. Utility Model Content

[0007] In another preferred embodiment, at least two first holes are provided on the anchor tooth, a second hole is provided on the connecting wing, and the positioning pin is provided through any one of the first hole and the second hole.

[0008] In another preferred embodiment, the other end of the anchor tooth is extended toward the direction close to the other end of the anchor rod.

[0009] In another preferred embodiment, the other end of the anchor tooth is extended toward the direction close to the other end of the anchor rod.

[0010] In another preferred embodiment, the width of the anchor tooth gradually decreases from one end to the other end.

[0011] In another preferred embodiment, it further comprises: a counterweight, wherein the counterweight is installed on the anchor rod.
