Problems solved by technology

[0004] For the concept of floating reefs for marine ranching, the existing common method is to use existing reefs (existing reefs such as figure 1 On the basis of the above), a floating body is hoisted by a rope on the upper part of the reef to realize the suspension of the reef in the water, but the floating reef obtained in this way is not stable in the water, and it is not conducive to fish spawning. The fish eggs are easily washed off the reef under the impact of the current, so the protection of the fish eggs is not high

Embodiment 1

[0040] see Figure 2-12 Shown, flexible floating reefs for fish spawning and conservation, including:

[0041] The buoyancy assembly 10 is equipped with a rotatable rotating assembly 20 inside the buoyancy assembly 10,

[0042] The counterweight body 50 is arranged below the buoyancy assembly 10, and the counterweight body 50 is connected with the buoyancy ring 11 at the bottom of the buoyancy assembly 10 through the rope body 40,

[0043] On the same level, there are seven rolling elements 70 between the rotating assembly 20 and the buoyancy assembly 10, and the rotating assembly 20 and the buoyancy assembly 10 respectively have the first ring groove 13 and the second ring groove 13 that limit the moving distance of the rolling elements 70 up and down. In the ring groove 26 , the rolling body 70 can roll in the first ring groove 13 and the second ring groove 26 .

[0044] The present invention adopts the buoyant buoyancy assembly 10 as the fish reef, and the bottom is conne...

Embodiment 2

[0046] see Figure 2-12 As shown, the buoyancy assembly 10 includes at least two floating rings 11, and the floating rings 11 are fixed by connecting rods 12 arranged around them, and there is also a net between the floating rings 11 to close the annular space between the two floating rings 11. 30. Net clothing 30 is bonded with connecting rod 20 or adopts rope body or steel wire to be fixedly connected. The connecting rod 12 is selected to connect the two floating rings 11 to connect the netting 30 between the two floating rings 11 to form a cylindrical buoyancy assembly 10 through which the middle part passes. The invented floating rings 11 have nets 30 between them and the connecting rods 12 provide support and connection stability, so that the water inside the buoyancy element 11 can exchange water with the outside of the buoyancy element 10 through the nets 30 in real time, and the improvement of water circulation can reduce the The impact force of the water flow acting...

Embodiment 3

[0056]When the flexible floating fish reef for fish spawning and conservation of the present invention is actually used: the spacer 22 is welded to the rotating ring 23, and then the support column 25 is welded to the center of the spacer 22 to connect the two rotating rings 23 , on the buoyant column 24 in the inflated state, the segmental type is tied to tighten the rope 24a, and the buoyant column 24 is bonded between the rotating rings 23. When bonding, the position of the floating column 24 should correspond to the separation point of the spacer 22 In order to facilitate the installation of the isolation net 21, the isolation net 21 is bonded to the support column 25, the floating column 24, and the spacer frame 22 at the upper and lower ends or connected and fixed by steel wire or rope, so that the isolation net 21 forms a plane state, and after the installation of the rotating assembly 20 is completed , the buoyancy assembly 10 is assembled. When assembling the buoyancy ...

Abstract

The invention discloses a flexible floating fish reef for fish spawning and conservation and belongs to the technical field of marine ecological restoration. The flexible floating fish reef for fish spawning and conservation comprises a buoyancy assembly and a balance weight body; a rotating assembly capable of rotating is assembled in the buoyancy assembly, the balance weight body is arranged below the buoyancy assembly and connected to a lower floating ring of the buoyancy assembly through a rope body, and at least three rolling bodies are arranged between the rotating assembly and the buoyancy assembly on the same horizontal surface; the rotating assembly and the buoyancy assembly are provided with a first annular groove and a second annular groove which are used for limiting the vertical movement distances of the rolling bodies respectively, and the rolling bodies can roll in the first annular groove and the second annular groove. The flexible floating fish reef can resist different water flow impacts and is high in stability in water, the adhesion rate of fish eggs is high, the fish eggs are unlikely to fall off, and a good protection effect on fishes is achieved.

Description

technical field [0001] The invention belongs to the technical field of marine ecological restoration, and in particular relates to a flexible floating fish reef used for fish spawning and conservation. Background technique [0002] my country's marine ranching is based on the principle of marine ecosystems. In specific sea areas, artificial fish reefs, multiplication and release are used to construct or repair places needed for marine organisms to grow, reproduce, feed, or avoid enemies, so as to proliferate and maintain fishery resources and improve the ecology of sea areas. environment and realize the sustainable use of fishery resources. As the golden key to solve the contradiction between the sustainable utilization of marine fishery resources and the protection of the ecological environment, the construction of marine ranching is an important exploration to transform the development mode of marine fishery, and it is also an important measure to promote the development of...
