Fish reef

Abstract

The invention relates to a fish reef. The fish reef is characterized by comprising a first suspension fish reef body, a second suspension fish reef body and a positioning anchor. The first suspension fish reef body is connected with the second suspension reef body through a rope, the second suspension reef body is connected with the positioning anchor through a rope, the first suspension fish reef body is composed of a cover plate and a base, the cover plate and the base form a cavity, an air inflation device is arranged on the cover plate, and an air bag device is connected with the part, located inside the cavity, of the air inflation device. The second suspension fish reef body is a ball shell of a hollow structure, and multiple irregular holes are formed in the surface of the ball shell; multiple containing cavities are formed inside a positioning anchor body, inverted hooks are arranged inside the containing cavities and connected with protrusive blocks on the anchor body through pin shafts in a rotating mode, and limiting blocks are arranged outside the containing cavities; a conical cavity is formed below the anchor body, and an eccentric block is arranged inside the conical cavity. Suspension depth can be adjusted and controlled for manual propagation, stability is good, anchor dragging is not likely to occur, ecological performance is excellent, multi-water-layer propagation can be performed, and the propagation effect is good.

Description

technical field [0001] The invention relates to a fish reef. 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. Contents of the invention [0003] Aiming at the problems existing in the prior art,...
