Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0022] Such as figure 1 As shown, a fish-gathering structure that makes full use of wave energy includes a hollow reef body 1, a number of inlet and outlet holes 2 that are arranged on the outer side of the hollow reef body and communicate with the cavity of the hollow reef body, and a wave energy fish-gathering device. Hollow reefs are made of concrete. The bottom surface of the hollow reef is flat. The lower part of the inner cavity of the hollow reef body is provided with a mesh partition 4, and the mesh partition divides the inner cavity of the hollow reef body into upper and lower parts. Access holes are located above the mesh compartment. The outer surface of the hollow reef body is provided with installation grooves, and each installation groove is respectively inlaid with algae reef blocks 3 cultivated in a laboratory and attached wit...

Abstract

The invention discloses a fish gathering structure capable of making full use of wave energy, and aims to provide a fish gathering structure capable of supplying sufficient baits to fishes by raising nutrient substances precipitated on the seabed by means of stirring bottom sediments. The fish gathering structure comprises a hollow reef, a plurality of entrance and exit holes which are formed in the outer side face of the hollow reef and are communicated with the inner cavity of the hollow reef, and a wave energy finish gathering device, wherein the wave energy finish gathering device comprises a floating ball, a connecting rope and a sediment beating plate; the sediment beating plate is rotationally arranged on the side face of the hollow reef through a revolving shaft; a limiting rod for limiting the rotating angle of the sediment beating plate is arranged above the sediment beating plate, and is fixed on the hollow reef; one side of the sediment beating plate is provided with a connecting rod piece; the connecting rod piece and the revolving shaft are positioned on two opposite sides of the sediment beating plate; one end of the connecting rope is connected with the connecting rod piece, and the other end of the connecting rope is connected with the floating ball; the buoyancy of the floating ball is greater than the gravity of the sediment beating plate.

Description

technical field [0001] The invention relates to the field of fish reefs, in particular to a fish gathering structure that fully utilizes wave energy. Background technique [0002] Due to the deterioration of the marine environment and the over-exploitation and destruction of marine fishery resources, it is imperative to improve this problem through artificial means. Among them, artificial fish reefs are used to improve the ecological environment of the sea area and create a habitat for marine organisms. It has achieved good results in providing places for shelter, growth and reproduction, etc. for fish. [0003] Present artificial fish reefs are usually made of objects such as stones, concrete blocks, and discarded vehicles and boats. The current design of artificial reefs is mainly aimed at how to provide shelter, growth and reproduction places for fish, etc.; however, little consideration is given to how to stir up the seabed sediments through the fish reef structure, so ...
