Abstract

The invention discloses a self-sinking suction anchor, which comprises an anchor body, wherein radially arranged telescopic hooks are arranged on the anchor; a symmetrically arranged inward concave movable cavity which can accommodate part of telescopic hooks is formed on the anchor body; a convex structure is formed near the bottom of the movable cavity, and stopping hooks are formed near the end parts of the telescopic hooks in the movable cavity; the top end of the anchor body has a through hole which runs through to the movable cavity; a spring is arranged on the part, which is close to the movable cavity, of the through hole; one end of the spring is connected with the end part of the telescopic hooks in the movable cavity, and the other end of the spring extends into the through hole and is sealed and fixed by a sealing and fixing screw in the through; and the top end of the anchor body is provided with a connecting ring. When the anchor body sinks, the telescopic hooks enter a seabed by a small acute angle to facilitate sinking. When under a pull force in an opposite direction, the telescopic hooks open transversely and are finally pressed to contract to deep positions in the movable cavity, so that a large stress area which is benefit for fixation is formed. The anchor has the advantages of variable resistance and desirable fixing effect.

Description

technical field [0001] The invention relates to a fish reef, in particular to a self-sinking suction anchor. Background technique [0002] As a fishery habitat improvement technology, artificial reef construction has played an important role in restoring fishery habitats and increasing fishery resources. The current research focus of fish reef technology is on the scientific research on the mechanism of artificial reef environment, while artificial reef As an important part of artificial reef construction, there is no in-depth research on the delivery technology and method. The deployment of artificial reefs plays a pivotal role in all aspects of artificial reef construction. Safe, accurate and efficient deployment of artificial reefs will not only enable artificial reefs to exert their maximum habitat transformation function, but also It saves a lot of manpower and material resources for the construction of artificial fish reefs. Existing artificial reefs, such as the Chi...
