Built-in self-locking pressure control anchor

Abstract

The invention provides a built-in self-locking pressure control anchor which comprises an anchor body, an anchor hook, an elastic torsion piece, a cylinder body, a pressure adjusting part, a limiting structure, and an elastic structure; the top of the anchor body is provided with an opening part, an embedding groove is formed in the anchor body, and a rotary connecting piece is assembled in the embedding groove; the anchor hook is assembled in the embedding groove and is rotationally connected to the rotary connecting piece; one end of the elastic torsion piece is fixed on the rotary connecting piece, and the other end of the elastic torsion piece abuts against the anchor hook; the cylinder body is connected to the lower portion of the anchor body and communicated with the anchor body, a containing cavity is formed in the anchor body, and a detachable deflation component is arranged at the bottom of the cylinder body; the pressure adjusting part is arranged in the containing cavity and is in sealed connection with the wall of the containing cavity; the limiting structure is formed on the pressure adjusting component and the anchor hook and used for limiting rotation of the anchor hook; and the elastic structure is arranged between the cylinder body and the pressure adjusting component. The problem that an existing anchor device is not firm in anchoring and prone to failure after being opened on the seabed is solved.

Description

technical field [0001] The invention relates to the technical field of underwater equipment, in particular to an anchor device for automatically propping up an anchor hook through changes in water pressure, that is, at a certain underwater depth. 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. The traditional mooring structure is mostly used in ships and buoy systems. The mooring chain is lowered and the anchor hook is released. It is not easy to deploy the underwater equipment and launch the launcher. Moreover, the anchor hook is easy to drop after falling into the seabed. The anchor hook is not firm and fails due to encou...

The traditional mooring structure is mostly used in ships and buoy systems. The mooring chain is lowered and the anchor hook is released. It is not easy to deploy the underwater equipment and launch the launcher. Moreover, the anchor hook is easy to drop after falling into the seabed. The anchor hook is not firm and fails due to encountering obstacles
