[0018] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples, and it should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0019] Referring to Figure 1 , Figure 2 and Figure 3The application provides an artificial fish reef, which comprises a plurality of artificial fish reef units connected together, the plurality of artificial fish reef units 0 jointly forming an artificial fish reef as a whole; adjacent artificial fish reef units are connected through a connecting piece 5 and have a movable gap 7 therebetween; the artificial fish reef as a whole has relative flexibility (the movable gap between the artificial fish reef units 0 can be adjusted by external force), so as to reduce the strength of the artificial fish reef as a whole, and the multi-section structure of the artificial fish reef as a whole is not easy to be damaged by deformation after being impacted by water flow.

[0020] Each artificial fish reef unit comprises a fish reef unit body 1 which is surrounded by a plurality of surfaces and forms a channel inside, and the side wall of the fish reef unit body 1 is a multi-layer structure with a filling gap arranged between adjacent surfaces; and the side wall of the fish reef unit body 1 is provided with an opening 2. In use, when the artificial fish reef is placed in a breeding pool or a breeding area in the sea, a counterweight material (such as concrete, gravel, etc.) needs to be filled in the filling gap 12 to ensure that the artificial fish reef has sufficient sinking effect. Of course, if the artificial fish reef itself is made of a material with sufficient counterweight such as metal or ceramic, the filling gap can not be filled. Then, feed or other attractants such as seafood (which can be adhered to the inner wall) are placed in the fish reef unit body 1, and the seafood can enter the channel of the fish reef unit body 1 through the opening 2.

[0021] In the embodiment, the fish reef unit body 1 is formed by sleeving a plurality of sub-units 11 (the shapes and structures of the plurality of sub-units 11 are consistent) inside and outside, and a filling gap 12 is formed between the adjacent sub-units 11 inside and outside.

[0022] The fish reef unit body 1 is provided with a space communication port 3 at the end, so as to communicate the channels inside the adjacent fish reef unit bodies 1 after assembly. Through the space communication port 3, the seafood can move in the channel of the artificial fish reef unit 0, thereby increasing the activity space of the seafood in the artificial fish reef. The number of the space communication ports 3 of each fish reef unit body 1 can be set as needed, which can be one, two or even more. In the embodiment, the fish reef unit body 1 is a cylindrical structure with two groups of space communication ports 3 arranged oppositely. The structure is set to facilitate processing to some extent.

[0023] After connection, the plurality of artificial fish reef units 0 form a long strip-shaped artificial fish reef structure, which is longitudinally placed in a breeding area and connected with a suspended platform 01 at the end during use.

[0024] On the basis of the above structure, the connecting piece 5 connects the end of the space communication port 3 of the adjacent fish reef unit body 1; and the connecting range of the connecting piece 5 covers the space communication port 3, specifically, the connecting piece 5 covers the space communication port 3 inside.

[0025] In the first embodiment, the connecting member 5 can be a flexible sleeve structure (also a cylindrical structure), and the end of the sleeve structure is connected with the end of the space communication port 3 of the adjacent artificial reef unit 0.

[0026] In the embodiment, a plurality of connecting members 5 are arranged on the side wall of the space communication port 3 in a ring shape, and the connecting members 5 are arranged on the periphery of the space communication port 3 in an equidistant manner; the side wall of the space communication port 3 is provided with a connecting hole 6; and the two ends of each connecting member 5 are connected with the connecting hole 6 of the side wall of the space communication port 3 of the adjacent artificial reef unit, respectively, so that the adjacent artificial reef units are connected by the connecting member 5. As shown in the figure, the connecting member 5 is in the form of a ring buckle, and of course, the connecting member 5 can also adopt other structures.

[0027] Preferably, the side wall and the inner wall of the artificial reef unit body 1 are provided with a texture structure for increasing friction to facilitate the adsorption of seafood, and the smoothness of the side wall of the artificial reef unit body 1 is reduced by the texture structure to facilitate the adsorption effect of the seafood. In the embodiment, the texture structure is a plurality of annular protrusions 4 which are perpendicular to the axis of the artificial reef unit body 1 and are arranged along the axis in an equidistant manner.

[0028] In summary, the present application provides an artificial reef unit, which comprises a reef unit body formed by a plurality of surfaces and having a channel formed inside, and a plurality of layers are arranged between the adjacent side walls of the reef unit body to fill the gaps; and the side wall of the reef unit body is provided with an opening. When the artificial reef is placed in a breeding pond or a breeding area in the sea, the filling gap needs to be filled with a counterweight material (such as concrete, gravel, etc.) to ensure that the artificial reef has sufficient sinking effect, and of course, if the artificial reef itself is made of metal or ceramic materials with sufficient counterweight, the filling gap can not be filled. Then, feed or other attractants such as seafood are placed in the reef unit body, and the seafood can enter the channel of the reef unit body through the opening. The present application changes the filling material in the filling gap to change the sinking and floating effect of the artificial reef unit, and the unit has a regular shape and is convenient to arrange.

[0029] Of course, the present application can have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application, but these corresponding changes and modifications should all belong to the protection scope of the claims attached to the present application.
