Floating structure of bionical artificial fish nest, including floating big floater 100 on the surface of water, big floater 100 can supply the fixed rope connection of fixed bionical artificial fish nest for fixed rope suspension is in the river, and a plurality of big floaters 100 are plane dot matrix formula interval arrangement, connects through flexible connection rope 101 between the adjacent big floater 100, and a plurality of big floaters 100 and connection rope 101 are connected and are network structure.
The periphery of the mesh structure is provided with a plurality of flexible cables 102, and the plurality of cables 102 are arranged around the periphery of the mesh structure; fixed piles are arranged in the river and are submerged in the river; the inner end of the cable 102 is connected to the outer periphery of the mesh structure and the outer end of the cable 102 is connected to the spud, the cable 102 being in a flexible slack form. Thus, the entire net structure is anchored and floated by connecting the cables 102 to the piles, and the floating structure is prevented from deviating from the set range.
The bottom of the net structure is paved with a film layer 700 floating on the water, a plurality of closed inner holes 701 are arranged in the film layer 700, the lower parts of a plurality of large floating balls 100 penetrate through the film layer 700 and are fixedly connected with the film layer 700, and the connecting rope 101 is positioned at the top of the film layer 700.
Through laying membranous layer 700, can be so that whole network structure is in plane arrangement, and set up inside hole 701 in membranous layer 700, can increase membranous layer 700's buoyancy, utilize and a plurality of big floater 100 between be connected, guarantee that membranous layer 700 is plane laying, connect rope 101 to be located membranous layer 700, avoid connecting rope 101 to stir and mix the overlap joint.
Above-mentioned floating structure of bionical artificial fish nest that provides, through set up a plurality of big floater 100 on the river surface of water, adjacent big floater 100 is connected through connecting rope 101 and is network structure, whole network structure floats on the river surface of water, it floats with whole network structure anchoring through hawser 102, the fixed rope that is provided with bionical artificial fish nest can connect on big floater 100, thus, bionical artificial fish nest then can simulate natural habitat floating state, create artificial natural habitat for fish, the realization makes fish lay eggs, seek food, perch, shelter as an organic whole, return nature, incorporate into natural habitat protective measures.
The cable 102 is connected to the large float 100 on the outer periphery of the mesh structure to facilitate the connection of the cable 102 to the mesh structure. The net structure is quadrilateral in shape and the cable 102 is connected to large floats 100 located at the corners of the net structure.
In this embodiment, the middle of the cable 102 is connected with a suspension body, and the suspension body is in a straight strip shape; the suspension body is provided with a lower section 300 which is suspended under water and an upper section 301 which floats on the water surface, wherein the lower section 300 is solid, the upper section 301 is closed and hollow, and the diameter of the upper section 301 is smaller than that of the lower section 300.
The suspension body is arranged in the middle of the cable 102, the lower section 300 of the suspension body is solid and is suspended in a river, and the upper section 301 of the suspension body is hollow and floats on the water surface, so that the suspension body can play a role in pulling the cable 102, and the floating movement of the whole floating structure is prevented from deviating from a set range. Secondly, in the process of the up-and-down floating change of the water surface of the river, the suspension body also floats up and down along with the floating change of the water surface, the pulling effect on the mooring rope 102 is kept, and the position deviation of the floating structure in the floating process is dynamically limited.

Thus, by arranging the annular cover 302 and submerging the bottom of the annular cover 302 under the water surface, the balance of the whole suspension body can be kept, the suspension body is kept in a longitudinal arrangement, and the buoyancy of the suspension body after submerging into the water surface is increased.
A cavity 402 is arranged inside the large floating ball 100, a cavity opening 404 is arranged at the bottom of the large floating ball 100, and the cavity opening 404 is communicated with the cavity 402; the upper end of the fixed rope is provided with a small floating ball 403, the small floating ball 403 is arranged in the cavity 402, the diameter of the small floating ball 403 is smaller than that of the cavity 402, and the diameter of the small floating ball 403 is larger than that of the cavity opening 404.
When the large float ball 100 is placed on the water surface, the lower part in the cavity 402 is filled with water, and the upper part in the cavity 402 is in an empty state. The small floating ball 403 is arranged in the cavity 402 and cannot be separated from the cavity opening 404, and the small floating ball 403 is in a floating state in the cavity 402, so that when the water surface of the river floats and changes, the fixed rope is limited by double-layer floating change along with the floating change of the floating structure and cannot be directly pulled by the floating structure, and the floating change flexibility of the fixed rope is ensured.
The side wall of the large floating ball 100 is provided with a plurality of communication holes 401, the communication holes 401 are communicated with the cavity 402 and the outside, along with the floating change of the river water surface, water can enter or discharge from the cavity 402 through the communication holes 401, and the water can conveniently flow between the cavity 402 and the outside.
In this embodiment, an adjusting float 600 floating on the water surface of a river is disposed between two adjacent large floats 100, two sides of the adjusting float 600 are provided with hard strips 601, one end of each hard strip 601 is hinged to the adjusting float 600, and the other end of each hard strip 601 is hinged to the large float 100. Thus, when the adjacent floating balls approach each other, the two hard strips 601 press the adjusting floating body 600 to sink into the river, at this time, the buoyancy of the adjusting floating body 600 is increased, and the adjusting floating body 600 drives the two hard strips 601 to abut against and separate from the two large floating balls 100 which approach each other until the adjusting floating body 600 and the two hard strips 601 accept and stabilize, so that the distance between the adjacent large floating balls 100 can be kept within the dynamic setting range by adjusting the floating body 600 and the two hard strips 601.
The middle part of the cable 102 between the two big floating balls 100 is fixedly connected with the top of the adjusting floating body 600. Therefore, the connection rope 101 between the adjacent large floating balls 100 can be pulled in the process of up-and-down floating of the adjusting floating body 600, the phenomenon that the connection rope 101 is knotted can be avoided, and the two large floating balls 100 which are close to each other are driven to be separated by the two hard strips 601 conveniently.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
