Description

Technical Field

[0001] This utility model relates to fish nest structures, and more particularly to a fish nest structure that adapts to changes in water level. Background Technology

[0002] Rivers are the main channels for flood discharge during the flood season, characterized by high flow velocity and high water levels. In areas with high flow velocity, ecological block revetments are often used to meet the requirements of erosion resistance and ecology during the flood season. These revetments are characterized by simple construction, stable root systems for plant growth, and good greening effects.

[0003] However, existing ecological blocks are only connected to the water body through small holes in the blocks themselves or the joints between the blocks. The internal filling space is mostly filled with soil, lacking water-facing habitat space. This makes it impossible to provide habitat space for aquatic animals, especially fish. Moreover, the habitat space cannot adapt to changes in river water level. When the water level rises or falls, the habitat space cannot be used by fish, ultimately affecting the riparian ecological environment. Utility Model Content

[0032] Example 1

[0033] like Figures 1-2 This embodiment provides a fish nest structure that adapts to water level changes, including: several adjacent base blocks 1; several adjacent protective boxes 2, one end of the protective box 2 is connected to the base block 1, the protective box 2 is provided with a channel 201, and the protective box 2 is provided with several through holes 202 at intervals along the direction of gravity, and the several through holes 202 are all connected to the channel 201.

[0034] Specifically, the foundation block 1 is located at the toe of the embankment 4, and the foundation block 1 needs to be buried in the riverbed 5. At the same time, the depth of the foundation block 1 buried in the riverbed 5 is not less than 1.5 times the maximum theoretical calculated depth. The foundation block 1 is used to support the protective box 2. The number of foundation blocks 1 is not limited and can be determined according to the length of the embankment 4. The protective box 2 is used to form a channel 201 and several through holes 202. Since the several through holes 202 are spaced apart along the direction of gravity, it is convenient for water flow and fish to enter the channel 201 through the several through holes 202, thereby facilitating adaptation to water level changes and providing habitat space for fish. The number of through holes 202 is not limited, but in order to ensure the overall strength of the protective box 2, the total area of ​​the several through holes 202 shall not exceed half of the total area of ​​the plane where the several through holes 202 of the protective box 2 are located.

[0035] Furthermore, such as Figures 1-2 The protective box 2 includes an ecological protection plate 21 and a fastening plate 22 that are connected to each other.

[0040] Specifically, the first cut 212 and the second cut 251 are connected to facilitate the flow of water and fish, thereby providing a habitat for fish. The material of the ecological block 25 is preferably a porous foam material, which facilitates the substrate conditions for microbial attachment and vegetation growth.

[0041] Furthermore, such as Figures 1-2 The ecological protection plate 21 and the fastening plate 22 are connected by several bolt assemblies 26.

[0042] Specifically, the bolt assembly 26 facilitates a strong connection between the ecological protection plate 21 and the fastening plate 22.

[0043] Furthermore, such as Figures 1-2 The basic block 1 includes: a block body 13, which is connected to one end of the ecological protection plate 21 and one end of the fastening plate 22; a first step 11 and a second step 12 are respectively connected to both sides of the block body 13, the first step 11 abuts against the curved part 211, and the second step 12 abuts against the fastening plate 22.

[0044] Specifically, the first step 11 and the second step 12 are used to limit the movement of the protective box 2, preventing the protective box 2 from moving in the horizontal direction.

[0045] Furthermore, such as Figures 1-2 The block bodies 13 of adjacent base blocks 1 are connected by connecting rods 31.

[0046] Specifically, the connecting rod 31 is used to increase the connection strength of the block body 13 of the adjacent base block 1.

[0049] Specifically, the H-type protective plate 27 is preferably made of a mixture of nylon fiber and thermosetting resin, which has the advantages of being lightweight, durable, wear-resistant and easy to process; the top cover 28 is used to seal the protective box 2.

[0050] Furthermore, such as Figures 3-4 The base block 1 includes: a block body 14, one end of which is connected to the H-shaped protective plate 27; and a protrusion 15 connected to the block body 14, which is located in the second cavity 271 of the H-shaped protective plate 27.
