Description

Special protector for submarine pipeline laying Technical Field The utility model relates to the technical field of submarine pipeline protection, in particular to a special protection device for submarine pipeline laying. Background The petroleum and the natural gas are used as important natural resources and are applied to aspects in life, but due to the fact that the resources on the ground are gradually exhausted due to the fact that the petroleum and the natural gas are excessively extracted, people transfer an extracted target to the sea floor, and in the sea floor extraction process, the extracted petroleum and the extracted natural gas need to be transported to the ground, so that the construction of a submarine pipeline has important significance for achieving open sea oil gas development. However, the protection device is also subjected to the resistance of seawater in the concrete operation of sinking the sea, and is inconvenient to operate, and a structure capable of reducing the resistance of the seawater and improving the protection performance is required, so that the energy consumption is reduced, the protection effect is improved, and the ecology is friendly, so that the special protection device for submarine pipeline laying is necessary. Disclosure of utility model The utility model mainly aims to provide a special protection device for submarine pipeline laying, which can effectively solve the problems in the background technology. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The special protection device for submarine pipeline laying comprises a protection block, wherein trapezoid grooves are formed in the lower surface of the protection block, fixing plates are symmetrically arranged on the lower surface of the protection block, fixing blocks are fixedly connected to the upper surface of the fixing plates, hanging rings are rotatably connected to the middle of the fixing blocks, gaps are formed in the outer surfaces of the protection block, planting grooves are formed in the outer surfaces of the protection block, and seaweed seed bags are fixedly connected to the inner side walls of the planting grooves. In order to achieve the purpose of protecting the outside of a pipeline, the special protection device for laying the submarine pipeline is characterized in that a steel rope is fixedly connected to the lower surface of the trapezoid groove, and a protection mechanism is fixedly connected to one end of the steel rope. In order to achieve the purpose of fitting the outside of a pipeline, the special protection device for submarine pipeline laying comprises an anti-corrosion hexagonal shell, wherein sand bags are arranged in the middle of the anti-corrosion hexagonal shell, the anti-corrosion hexagonal shell is arranged in a plurality, the anti-corrosion hexagonal shell is arranged in a linear array mode, and anti-corrosion ropes are hinged between the anti-corrosion hexagonal shells. In order to achieve the purpose of convenient fixation, the special protection device for submarine pipeline laying is characterized in that four corners of the lower surface of the fixing plate are fixedly connected with fixing bolts, and the lower surface of each fixing bolt is fixedly connected with a drill bit.
