Description

Technical Field

[0001] The present invention relates to wetland ecological restoration engineering technology and wetland biodiversity restoration technology, and in particular to a combined biological habitat platform for rapidly creating a bird microhabitat. Background Art

[0002] As mid- and high-level consumers in the food chain, birds are highly sensitive to environmental changes, making them important indicator species in ecosystems and a vital component of urban ecosystems. However, with the rapid development of urbanization, natural waterfront areas, which serve as important bird habitats, have become increasingly hardened, verticalized, and artificial. The shrinkage and fragmentation of bird habitats are becoming increasingly serious, leading to a decline in bird diversity and populations. Current waterfront restoration and bird habitat creation projects often require large amounts of earth and stone filling to restore the gradient structure of the natural waterfront. This is slow and costly, and earth filling and transportation are strictly restricted within water source protection areas. Therefore, a technical method for quickly and cost-effectively creating waterfront bird habitats is urgently needed.

[0003] Birds have specific habitat requirements, including food sources, shelter, and places to breed and nest. Currently, floating structures that provide bird habitats on waters fall into two main categories: traditional floating structures, which, while simple to manufacture and made from simple materials, have limited structure and functionality, a short lifespan, and struggle to maintain long-term bird habitats. These structures, along with the new artificial floating islands, offer complex structures and diverse functions compared to traditional floating structures. However, these structures are often limited in their use scenarios, resulting in limited applicability and high costs.

[0004] Ecological floating islands, a method for quickly creating green areas on water, have been widely used for water purification and environmental beautification. They occupy a small footprint, are simple to operate, and offer significant purification effects. They can significantly improve water clarity while restoring aquatic ecosystems and providing a suitable habitat for birds and aquatic plants. However, existing ecological floating islands still have limitations in creating bird habitats and restoring biodiversity.

[0005] Specifically, some ecological floating islands lack sufficient stability and are easily disturbed by natural factors such as wind and waves. Some islands lack appropriate vegetation configuration and animal introduction strategies, resulting in poor biodiversity restoration. Still others are unable to maintain the conditions necessary for plant growth over the long term, leading to a gradual decline in their functionality. These issues limit the effectiveness of ecological floating islands in creating bird habitats and restoring biodiversity.

[0006] To protect and restore bird habitats, modular ecological floating islands can be used to expand bird habitats and activity areas on the water surface, thereby addressing the aforementioned issues. Modular ecological floating islands offer numerous advantages over traditional ecological floating islands. They can be flexibly combined to suit different water environments and bird habitat needs, achieving multifunctionality and customization. By adjusting the size, shape, and plant configuration of the floating islands, a more suitable habitat for birds can be created. Furthermore, modular ecological floating islands are easy to install and maintain, reducing construction and operating costs.

[0007] The existing modular ecological floating island technology has a relatively simple function in the field of wetland ecological restoration and biodiversity restoration. It is generally used for short-term population restoration of a certain species. There has not yet been a case of sustainable ecological restoration and biodiversity restoration by creating a complete micro-ecosystem. Existing technology has also not been able to fully utilize the combination of floating islands with different drafts to construct gradient habitats to meet the different foraging water depth requirements of different species of waterbirds and further enrich the spatial hierarchy of bird microhabitats. Therefore, there is an urgent need for a modular biological habitat platform that can quickly create bird microhabitats and has high flexibility and stability to promote the effective restoration of the integrity and stability of wetland ecosystems. Summary of the Invention

[0008] In response to the above-mentioned technical problems, the present invention provides a combined biological habitat platform for quickly creating a microhabitat for birds.

[0009] The technical solution of the present invention is: a modular biological habitat platform for quickly creating a bird microhabitat, the platform being composed of multiple biological habitat platform units; each biological habitat platform unit comprising a plurality of interconnected main body splicing units, a buoyancy unit disposed on the outer side wall of the main body splicing unit, fixing bolts for connecting the main body splicing unit and the buoyancy unit, and a vegetation layer laid on the upper end surface of the main body splicing unit;

[0010] The main splicing unit includes a square frame and several buoyancy columns equidistantly distributed inside the square frame; lug structures are provided at the four corners of the square frame, and each lug structure is penetrated by a mounting hole;

[0011] The buoyancy unit includes a first buoyancy module arranged on the side of the square frame and a second buoyancy module arranged at the four corners of the square frame; both ends of the first buoyancy module are provided with a lug structure, and the second buoyancy module is also provided with a lug structure; the lug structures on adjacent square frames, first buoyancy modules, and second buoyancy modules overlap with each other, and the overlapping lug structures are fixed by fixing bolts; the upper end surface of each first buoyancy module is provided with a water injection pipe, and the lower bottom surface is provided with a drainage pipe;

[0012] The vegetation layer comprises a cushion layer laid on the upper end surface of the main splicing unit, a matrix laid above the cushion layer and plants planted on the matrix.

[0013] Furthermore, hexagonal holes are provided inside the lug structure and at both the upper and lower ends of the mounting hole; the fixing bolt includes a round table and a first screw provided on the bottom surface of the round table; a limiting protrusion capable of movably engaging with the hexagonal hole is provided on the outer wall of the round table;

[0014] Note: When the first screw is inserted into the mounting hole on the stacked lug structures, the limiting protrusion on the outer wall of the cone can engage with the hexagonal hole on the lug structure to prevent the first screw from rotating during the tightening process.

[0015] Furthermore, a gasket is provided between each of the two adjacent lug structures and is sleeved on the screw at the corresponding position; a connecting hole is provided through the gasket, and a hexagonal boss is provided on the gasket and at both ends of the connecting hole, which can be movably engaged with the hexagonal hole;

[0016] Description: By using the hexagonal boss on the gasket and the hexagonal holes on the two adjacent lug structures to interact and snap fit, the height difference between the main splicing unit and the buoyancy unit can be adjusted when connected.

[0017] Furthermore, each buoyancy column is provided with an annular groove;

[0018] Description: By setting annular grooves on the buoyancy columns, a tortuous gap is formed between two adjacent buoyancy columns, allowing the roots of aquatic plants to grow through the gap. This not only establishes a close connection between the vegetation layer and the water environment, but also enhances the stability and durability of the platform by having the roots entangled around the main splicing unit.

[0019] Furthermore, a first serration is provided on the outer side wall of the square frame in a circumferential direction, and a second serration is provided on the inner side wall of the first buoyancy module, which can be movably engaged with the first serration; a third serration is provided on both ends of the first buoyancy module, and a fourth serration is provided on both ends of the second buoyancy module, which can be movably engaged with the third serration;

[0020] Note: The clamping effect of the first and second serrations can improve the connection strength between the square frame and the first buoyancy module; the clamping effect of the third and fourth serrations can improve the connection stability and aesthetics between the first and second buoyancy modules.

[0021] Furthermore, the lower bottom surface of each square frame is provided with a rod-shaped interface;

[0022] Description: By setting up a square frame, it is easy to connect the main splicing unit with ecological units such as underwater artificial reefs.

[0023] Furthermore, each lug structure is slidably engaged with the square frame, the first buoyancy module, and the second buoyancy module at the corresponding position through a sliding guide rod; a first slot is provided on the side wall of the square frame; a second slot is provided on the side wall of the first buoyancy module, and an I-shaped retainer is movably engaged between the first slot and the second slot at the corresponding position; the I-shaped retainer is fixedly connected to the first slot and the second slot through a second screw.

[0024] Note: By setting up an I-shaped retainer, the connection stability between the main splicing unit and the buoyancy unit can be improved, and the deformation and falling off of the lug structure caused by excessive torque at the connection between the lug structure and the square frame can be avoided when the platform is used in harsh environments.

[0025] The installation method of the present invention comprises the following steps:

[0026] S1, assemble the main splicing unit;

[0027] Arrange several main body splicing units according to a predetermined layout, connect them using the lug structures and fixing bolts on the main body splicing units, pass the first screw through the mounting hole in the lug structure of the adjacent main body splicing units, and tighten with a nut to ensure a stable connection between the main body splicing units;

[0028] S2. Adjust the height and splice the buoyancy unit;

[0029] Place a gasket on the lug structure of the main assembly unit and adjust the height of the gasket as needed to ensure that the lug structures of the main assembly unit are at the same height. Then, stack the left lug structure on the first buoyancy module on the lug structure of the main assembly unit. Finally, use a screw to pass through the mounting holes of each lug structure in sequence and tighten it with a nut. Stack the lug structure on the second buoyancy module on the lug structure of the first buoyancy module. Finally, use a screw to pass through the mounting holes of each lug structure in sequence and tighten it with a nut. The above steps form a biological habitat platform unit.

[0030] S3. Placement of biological habitat platform units, laying of vegetation layer and adjustment of draft depth;

[0031] Select a suitable placement location and place the assembled biological habitat platform unit in the designated water area. Then, lay the vegetation layer on the main splicing unit. The steps are: laying the cushion layer and filling the substrate, planting wetland plants, covering with sand and gravel, and piling up dead wood and rocks. The draft of the biological habitat platform unit is adjusted as needed through the water inlet and outlet of the buoyancy unit.

[0032] S4, fixation of biological habitat platform;

[0033] Use anchoring to fix the biohabitat platform on the water surface. Connect two 50kg iron anchors to the main splicing unit 1 at both ends of the biohabitat platform. The length of the anchor rope used should be three times the water depth. Alternatively, use water piling to fix the biohabitat platform on the water surface. It is suitable for nearshore shallow waters with a water depth of less than 3-5 meters.

[0034] S5, repeated splicing and gradient combination to form a complete biological habitat platform;

[0035] As needed, steps S1-4 are repeated to assemble biological habitat platform units of different drafts, and then the biological habitat platform units of different drafts are combined to form a larger-scale complete modular biological habitat platform.

[0036] Compared with the prior art, the beneficial effects of the present invention are embodied in the following aspects:

[0037] First, the present invention simulates the morphology and ecological functions of natural islands through ingenious platform structure design, cushion matrix optimization, reasonable plant configuration and planting density, and draft depth adjustment, creating a diverse habitat on the water suitable for waterfowl and amphibians to rest, forage, hide, and build nests;

[0038] Second, the present invention can be quickly constructed and flexibly assembled to adapt to different water environments and ecological needs, greatly improving the efficiency of creating bird microhabitats in wetland ecological restoration projects;

[0039] Third, the zigzag gaps formed between the buoyancy columns of the present invention provide space for the growth of plant roots. After the plant roots grow through the gaps, they not only establish a close connection between the vegetation layer and the water environment, but also enhance the stability and durability of the platform by wrapping around and embracing the main splicing units.

[0040] Fourth, the buoyancy unit of the present invention has an adjustable water injection function. By changing the water injection volume, the draft depth of the floating island can be flexibly adjusted, forming a gradient habitat, meeting the different foraging water depth requirements of different species of waterfowl, further enriching the spatial hierarchy of bird microhabitats, and improving the protection level of wetland biodiversity;

[0041] Fifth, the main splicing unit of the present invention is provided with a columnar interface at the bottom, which is convenient for connection with ecological units such as underwater artificial fish reefs, thereby constructing a stable ecosystem that is integrated above and below the water, has a complete food chain, and is rich in biodiversity. It provides a more suitable habitat for wetland organisms such as birds, and effectively promotes the restoration of the integrity and stability of the wetland ecosystem.
