Built-in water injection pressure control anchor

Abstract

The invention discloses a built-in water injection pressure control anchor which comprises a bin body which comprises a lower bin body. A connecting piece is vertically arranged on the lower bin body and is at least connected with the top wall of the lower bin body in a sliding and sealing manner; a lower end cover is fixed to the bottom of the lower bin body, and a containing cavity is formed in the lower end cover and provided with a first water injection part and a first outlet part; an anchoring device is arranged in the containing cavity and comprises an anchor fluke piece, and the anchor fluke piece faces the first outlet part; an anchor rod is fixedly connected with the anchor fluke piece; a sliding piece is arranged at the end of the anchor rod, is in sliding sealing connection with the containing cavity and faces the first water injection part, and the cross section area of the sliding piece is larger than that of the anchor rod; a sliding cavity is communicated with the inner space of the lower bin body; a lower plugging piece is fixedly connected with the connecting piece and is in sliding sealing connection with the sliding cavity; and a second water injection part is communicated with the sliding cavity. The problems that in the prior art, an anchor structure is inconvenient to lay and cast underwater equipment, and the occupied space is large are solved.

Description

technical field [0001] The invention relates to the technical field of underwater equipment, in particular to a built-in water injection pressure control anchor which automatically props up the anchor at a certain underwater depth by generating a pressure difference under the action of water pressure. Background technique [0002] With the continuous deepening of the development and utilization of marine resources by human beings, especially the proposal of the national marine power strategy, many underwater equipment have emerged as the times require. In many cases, underwater equipment needs to be fixed on the seabed through an anchor structure to ensure the stability and safety of the equipment. Traditional mooring structures are mostly used in ships and buoy systems. Most of them use anchor chains to be lowered and anchor claws to release structures. The structure takes up a lot of space.

AI Technical Summary

Problems solved by technology

[0003] This invention aims at the problem that the anchor structure in the prior art is not convenient for underwater equipment deployment and projection, and takes up a lot of space, and proposes a new type of built-in water injection pressure Control the anchor, use the water pressure to realize the automatic operation of the anchor structure through its own mechanical structure, and the built-in anchor claws will automatically unfold outwards to reduce the workload of deployment; the structure is simple, the anchor claws are integrated as a whole, occupying a small space, and are convenient for transportation and projecting
