Embodiment 1

[0026] A fixed floating ball type floating fish reef, such as figure 1 , figure 2 As shown, it includes: a floating reef main body 1, a connecting cable 2 and an anchorage 3.

[0027] The first end of the connecting cable 2 is connected with the main body 1 of the floating fish reef, and the upper surface of the anchorage 3 is provided with a connecting hook connected with the second end of the connecting cable 2 . Some artificial kelp 21 are fixed on the connecting cable 2, which helps to realize the characteristics of full-water deep fish reef effect.

[0028] The main body 1 of the floating fish reef includes: several hinges 11, a large mesh net clothing 12 and a buoyancy frame. Hinge 11 adopts PE or PVC material hinge, provides the fish reef of water surface layer while providing partial buoyancy. The large mesh net clothing 12 is fixed on the hinge 11 to form a closed mesh structure, which has strong water permeability and biological adhesion, and fish can gather free...

Embodiment 2

[0031] The iron bar 31 is a semi-cylindrical structure, the upper surface is provided with a seaweed base, the middle of the base is provided with a seaweed spore storage cavity, and the lower surface of the iron bar 31 is provided with a number of openings to facilitate the seaweed to take root on the seabed. Other parts of the structure are the same as in Embodiment 1.

Embodiment 3

[0033] The anchorage 3 is a solid iron block, and the lower surface is provided with some wedges. The top of the wedge is arrow-shaped and faces an angle of 30-60 degrees. Other parts of the structure are the same as in Embodiment 1.

Abstract

The invention discloses a fixed float ball type floating fish reef which comprises a floating fish reef body 1, a connecting cable 2 and a concrete anchor 3. A first end of the connecting cable 2 is connected with the floating fish reef body 1, and a second end of the connecting cable 2 is connected with the concrete anchor 3; the floating fish reef body 1 comprises a plurality of hinges 11, large-mesh netting 12 and buoyancy frames; the large-mesh netting 12 is fixed onto the hinges 11 to form closed netted structures; the buoyancy frames comprise a plurality of float ball sets 14 and a plurality of upright columns 13, and the float ball sets 13 are horizontally fixed onto the upright columns 13; the hinges 11 are mounted on the corresponding upright columns 13; the closed netted structures and the buoyancy frames are intermittently arranged, and the float ball sets 14 of bottom layers are connected with the first end of the connecting cable 2; the float ball sets 14 comprise a plurality of float balls which are serially connected with one another, and the float balls are arranged at intervals.

Description

technical field [0001] The invention relates to a fish reef, in particular to a fixed floating ball type floating fish reef. Background technique [0002] Artificial fish reefs are structures artificially set up in the sea. The purpose is to improve the ecological environment of the sea area, create a good environment for marine organisms to inhabit, and provide places for fish to reproduce, grow, feed and shelter enemies, so as to achieve protection, multiplication and The purpose of increasing catches. [0003] The country attaches great importance to and vigorously supports the construction of marine pastures in coastal areas. However, the average thickness of the silt layer in the East my country Sea is as high as 15m, which is difficult to carry the bottom fish reefs. reef failure. In order to solve the problem of constructing artificial fishing reefs in marine pastures with muddy bottoms, the research and development of new floating fish reefs has been systematically ...
