Abstract
Description
Technical Field
[0001] The utility model relates to the field of water conservancy project restoration, in particular to a fish nest type ecological slope protection building block. Background Art
[0002] Ecological slope protection is a slope protection technology based on ecological principles. It is primarily used in water conservancy projects such as rivers, reservoirs, and wetlands, as well as in highway construction and mountain restoration. Fish nest ecological slope protection is a type of ecological slope protection. Its overall structure uses blocks to form fish nests, providing a habitat for aquatic life and enhancing riverbank stability. The specific benefits of fish nest ecological slope protection are: First, it promotes fish reproduction: Fish nest ecological slope protection provides a safe and suitable breeding environment for fish, which is conducive to their reproduction and growth. Furthermore, by mimicking the breeding habits of fish in natural environments, it can also increase fish reproduction and survival rates. Second, it protects aquatic ecosystems: The use of fish nest ecological slope protection can effectively protect the ecological environment of aquatic areas. On the one hand, by promoting fish reproduction and growth, it can increase biodiversity in aquatic areas. On the other hand, the use of slope protection can also reduce soil erosion and river erosion, maintaining the stability of aquatic ecosystems. Third, it improves slope protection effectiveness: Compared with traditional slope protection methods, fish nest ecological slope protection blocks have better slope protection effectiveness. Because the blocks are equipped with independent fish nest structures, they can effectively disperse the scouring effect of water on the slope, reducing erosion and damage to the slope. At the same time, the use of blocks can also increase the roughness of the slope and improve the stability of the slope.
[0003] Existing fish nest-style ecological slope protection blocks have the following shortcomings: First, the blocks have a simple internal structure and a short hydraulic retention time, which makes them inadequate for providing habitats for fish and other aquatic animals. Strong currents can easily wash away resident fish or aquatic animals. Second, existing fish nest-style blocks only provide riverbank protection, a relatively limited function and lack effective ecological benefits.
[0004] The applicant has not found any patent document identical or similar to the present application in the domestic patent database. Summary of the Invention
[0005] The purpose of this utility model is to provide a fish nest type ecological slope protection block. By optimizing the internal structure design of the block and coordinating it with the structural design of the ecological base, it not only has a protective function, but also has a significant ecological effect. It can effectively extend the hydraulic retention time and provide a more stable growth environment for fish or aquatic animals. At the same time, the ecological base can also purify the river water quality.
[0006] The overall technical concept of the utility model is:
[0007] The fish nest type ecological slope protection block includes a block body, a through groove for accommodating vegetation, and a working surface provided on the surface and / or side of the block body for stacking and / or matching with adjacent blocks; a fixed frame of an ecological base is fixedly assembled at the front of the block body, and an opening is provided on the fixed frame for aquatic animals to pass through. The fixed frame and the rear wall of the block body extend in an interlaced manner in the direction of the through groove to form a fixed plate. The block body, the fixed plate and the through groove surround a fish nest with an S-shaped cross section. The baffle is located at the front end of the block body and its top is rotatably engaged with the top of the side wall of the block body.
[0008] The ecological base, also known as artificial aquatic plants, is a bionic aquatic plant or other form of object with a special pore structure made of suitable materials through fine processing. It can swing with the water flow, has a high specific surface area, and can adsorb and intercept organic matter. The ecological base contains microorganisms, which play a key role in biological filtration and biological conversion for eutrophic water bodies, black and smelly water bodies, etc.
[0009] When the eco-base is submerged in water, river weeds cling to it, nourishing microorganisms and aquatic life, attracting fish and other aquatic animals to their nests. Not only does this provide food, but the weeds' roots absorb nitrogen and phosphorus from the water, purifying the water within the nests. The eco-base is a mature technology and commercially available.
[0010] In order to facilitate the assembly and movement of the baffle, the baffle is preferably made of silicone material.
[0011] The specific technical solutions in this utility model are as follows:
[0012] In order to make the utility model better used in water conservancy, highway engineering or mountain restoration, and to facilitate adaptation to the sloped surface of the external environment to achieve stability of the overall structure after assembly, the preferred technical implementation means is that the outer surface of the rear wall of the block body is an inclined surface adapted to the external environment.
[0013] To facilitate the wrapping and positioning of the eco-base on the fixed frame, a preferred technical approach is to provide a latch at the upper and / or lower end of the fixed frame for positioning the eco-base, with the latch width being smaller than the opening width. This allows the eco-base to be effectively positioned on the fixed frame without completely blocking the opening, facilitating the entry and exit of fish and / or aquatic animals through the opening.
[0014] In order to facilitate the assembly and replacement of the ecological base and the fixed frame, the preferred technical implementation means is that the ecological base is wound around the fixed frame and positioned by the bayonet.
[0015] In order to facilitate the stacking and assembly of building blocks, ensure the stability of the assembled structure and facilitate the growth of aquatic plants, the preferred technical implementation method is that an upper cover is provided at the rear of the top of the building block body, and the top of the upper cover is raised to form a strip positioning block, which is adapted to the positioning groove opened at the bottom of the front side wall of the building block body.
[0016] The utility model can adopt a mold to form the block body according to needs during molding, and concrete material or reinforced concrete material can be selected according to the strength requirements of the block body. The upper cover can be molded together with the block body, or it can be molded separately and then fixedly assembled with the block body as a whole.
[0017] The substantial features and significant technical advancements of this utility model are:
[0018] 1. The utility model adopts a fish nest structure with an S-shaped cross section formed by a block body, a fixed plate, and a through groove, which can effectively prolong the hydraulic retention time and provide a favorable attachment and growth environment for river aquatic organisms.
[0019] 2. The utility model adopts a structural design of a baffle located at the front end of the building block body, which makes the opening on the fixed frame for fish and / or aquatic animals to pass through more flexible. The baffle opens when the water flows and automatically closes when the water does not flow. In the closed state, it can prevent fish and other aquatic organisms from being washed away by turbulent water, and can provide a stable habitat and breeding place for aquatic organisms.
[0020] 3. This utility model utilizes a structural design in which an ecological base is mounted on a fixed frame. First, the ecological base can absorb microorganisms in the water, allowing soluble organic matter in the water to fully contact the biofilm on the ecological base, thereby achieving biological filtration, bioconversion, and water purification. Second, it facilitates buffering water flow, effectively extending the contact time between pollutants and the ecological base, thereby degrading pollutants and providing a stable habitat for aquatic animals. The aquatic plants mounted on the ecological base can also serve as a food source for fish. While maintaining the existing functions of the building block, the building block achieves a transformation from a single hydraulic protection function to a comprehensive function of water purification and fish breeding.
[0021] 4. The present invention adopts a structural design of strip-shaped positioning blocks and matching positioning grooves, which can firstly increase the installation speed; secondly, facilitate the stability of the structure after assembly; and thirdly, the upper cover does not partially close the top of the block, which has little impact on the growth of aquatic plants.
