Embodiment 1
[0049] In this embodiment, the fish gate 2 is a continuous arched structure. The size of the fish door 2 can be calculated according to the water velocity, and the size should not be too large. The larger the size, the greater the flow force, and the greater the impact on the prefabricated concrete components of the ecological fish nest, and affect the structural strength of the fish nest. Simultaneously, the size of the fish door 2 should not be too small, which is unfavorable for slightly larger aquatic animals entering the box-type fish nest 1 to inhabit, reproduce or avoid natural enemies. The continuous arched fish gate 2 adopted in this embodiment not only has high strength, but also facilitates the adjustment of the size and the entry of aquatic animals.
Embodiment 2
[0051] In the present embodiment, aquatic plant connectors 5 are evenly distributed in the concrete box-shaped fish nest 1 , and superfine fiber artificial aquatic plants 4 are evenly distributed on the aquatic plant connectors 5 . The aquatic plant connector 5 can be set in different quantities according to the cavity size of the concrete box-shaped fish nest 1, and can be pre-embedded on the top of the wall or on the side wall of the wall, so as to facilitate the installation of superfine fiber artificial aquatic plants 4.
Embodiment 3
[0053] In this example, see Figure 4, The connector 3 includes a matching convex arc hinged connecting block 31 and a concave arc hinged connecting block 32, which are respectively arranged on both sides of the concrete box fish nest 1 along the length direction. These two hinged connections are in cylindrical contact, and cooperate with each other to form a relatively tight connection seam, which prevents the soil behind from leaking out of the connection, and has a good water and soil conservation function. The hinge joints protrude from the two ends of the concrete box-shaped fish nest 1, and the fish nest can be rotated forward and backward with the joint as the axis, so as to ensure the adaptability to river shorelines with different curvatures.
