Description

Technical Field

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

[0002] As middle and high-level consumers in the food chain, birds are highly sensitive to environmental changes. They are important indicator species in the ecosystem and an important part of the urban ecosystem. However, with the rapid development of urbanization, natural waterfront areas, which are important habitats for birds, have become hardened, verticalized, and artificial. The shrinkage and fragmentation of bird habitats are becoming increasingly serious, leading to a decline in bird diversity and population. Current waterfront restoration and bird habitat construction projects often require a large amount of earth and stone filling to restore the gradient structure of the natural waterfront, which is slow and costly. In addition, earth filling and transportation are strictly restricted in water source protection areas. Therefore, there is an urgent need for a technical method to quickly and low-costly create waterfront bird habitats.

[0003] Birds have specific requirements for habitats, including food sources, shelter, and places to breed and nest. Currently, floating facilities on water bodies that can be used by birds are mainly divided into two categories: one is traditional floating facilities, which are made of simple materials and easy to make, but have a single structure and function, a short service life, and are difficult to maintain bird habitats for a long time, and cannot be put into production practice on a large scale; the other is new artificial floating islands, which have complex structures and diverse functions compared to traditional floating facilities, but are often limited by usage scenarios, are not widely applicable, and are more expensive.

[0004] As a method of quickly creating green areas on water, ecological floating islands have been widely used in water purification and environmental beautification. They occupy a small area, are easy to operate, have significant purification effects, can significantly improve water transparency, and restore the water ecosystem, providing a suitable place for the reproduction of 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 floating islands lack reasonable vegetation configuration and animal introduction strategies, resulting in poor biodiversity restoration effects; and some floating islands cannot maintain the conditions required for plant growth for a long time, resulting in a gradual decline in function. These problems limit the application effect of ecological floating islands in bird habitat creation and biodiversity restoration.

[0006] In order to protect and restore bird habitats, the above problems can be solved by applying modular ecological floating islands to expand the habitats and activity areas of birds on the water surface. Modular ecological floating islands have more advantages than traditional ecological floating islands. They can be flexibly combined according to different water environments and bird habitat needs to achieve multifunctionality and customization. By adjusting the size, shape and plant configuration of the floating island, an ecological environment more suitable for bird habitat can be created. In addition, modular ecological floating islands are easy to install and maintain, reducing construction and operation costs.

[0007] The existing combined 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 technologies have also not been able to fully utilize the combination of floating islands with different draft depths to construct gradient habitats to meet the different foraging water depth requirements of different types of water birds and further enrich the spatial hierarchy of bird microhabitats. Therefore, there is an urgent need for a combined 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 view of 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 combined biological habitat platform for quickly creating a bird microhabitat, the platform is composed of a plurality of biological habitat platform units; each biological habitat platform unit includes a plurality of mutually connected main body splicing units, a buoyancy unit arranged on the outer side wall of the main body splicing unit, a fixing bolt 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 a plurality of buoyancy columns equidistantly distributed inside the square frame; lug structures are arranged at the four corners of the square frame, and mounting holes are arranged through each lug structure;

[0011] The buoyancy unit comprises 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; lug structures are arranged at both ends of the first buoyancy module, and lug structures are also arranged on the second buoyancy module; the lug structures on the adjacent square frames, the first buoyancy modules and the second buoyancy modules overlap with each other, and the overlapping lug structures are connected and 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 body splicing unit, a matrix laid above the cushion layer and plants planted on the matrix.

[0013] Furthermore, hexagonal holes are arranged inside the lug structure and at both ends of the mounting hole; the fixing bolt comprises a truncated cone and a first screw rod arranged on the bottom surface of the truncated cone; a limiting protrusion capable of being movably engaged with the hexagonal hole is arranged on the outer wall of the truncated cone;

[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 truncated cone can be engaged with the hexagonal hole on the lug structure to prevent the first screw from rotating during the tightening process.

[0015] Furthermore, a gasket sleeved on the screw at the corresponding position is provided between two adjacent lug structures; a connecting hole is provided through the gasket, and a hexagonal boss capable of being movably engaged with the hexagonal hole is provided on the gasket and at the upper and lower ends of the connecting hole;

[0016] Description: By utilizing the hexagonal boss on the gasket and the hexagonal holes on the two adjacent lug structures to interactively engage with each other, the height difference between the main splicing unit and the buoyancy unit can be adjusted when they are 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, so that the roots of aquatic plants can grow through the gap, which 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] Further, a first sawtooth portion is circumferentially provided on the outer side wall of the square frame, and a second sawtooth portion capable of being movably engaged with the first sawtooth portion is provided on the inner side wall of the first buoyancy module; a third sawtooth portion is provided at both ends of the first buoyancy module, and a fourth sawtooth portion capable of being movably engaged with the third sawtooth portion is provided at both ends of the second buoyancy module;

[0020] Description: The clamping effect of the first serration and the second serration can improve the connection strength between the square frame and the first buoyancy module; the clamping effect of the third serration and the fourth serration is beneficial to improve the connection stability and aesthetics between the first buoyancy module and the second buoyancy module.

[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 fish reefs.

[0023] Further, each lug structure is slidably connected 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 connected between the first slot and the second slot at the corresponding position; the I-shaped retainer is fixedly connected with the first slot and the second slot through a second screw rod;

[0024] Note: By setting an I-shaped retainer, the connection stability between the main splicing unit and the buoyancy unit can be improved, and the lug structure can be prevented from being deformed or falling off due to excessive torque at the connection between the lug structure and the square frame 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 lug structures and fixing bolts on the main body splicing units, pass the first screw through the mounting holes in the lug structures of adjacent main body splicing units, and tighten them with nuts 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, 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, and finally use a screw rod to pass through the mounting holes of each lug structure in turn and tighten it with a nut; stack the lug structure on the second buoyancy module on the lug structure of the first buoyancy module, and finally pass the screw rod through the mounting holes of each lug structure in turn and tighten it with a nut. The above steps form a biological habitat platform unit;

[0030] S3, placing biological habitat platform units, laying vegetation layers and adjusting draft depth;

[0031] Select a suitable placement location, place the assembled biological habitat platform unit into the predetermined waters, and then lay a vegetation layer on the main splicing unit. The steps are: laying a cushion layer and filling a matrix, planting wetland plants, covering with sand and stones, and stacking dead wood and stone piles; adjust the draft of the biological habitat platform unit 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 biological habitat platform on the water surface. Connect two 50kg iron anchors to the main splicing units 1 at both ends of the biological habitat platform. The length of the anchor rope used is 3 times the water depth. Alternatively, use water piling to fix the biological habitat platform on the water surface. It is suitable for nearshore shallow waters with a water depth of 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 with different drafts, and then the biological habitat platform units with different drafts are combined to form a larger-scale complete combined 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, draft depth adjustment, etc., to create a diverse habitat suitable for waterfowl and amphibians to rest, forage, hide and build nests on the water;

[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 buoyancy columns of the present invention form tortuous gaps, which can provide space for the growth of plant roots. After the plant roots grow through the gaps, a close connection between the vegetation layer and the water environment is established, and the roots wrap around and hold the main splicing unit, thereby enhancing the stability and durability of the platform;

[0040] Fourth, the buoyancy unit of the present invention has an adjustable water injection function. By changing the water injection amount, the draft depth of the floating island can be flexibly adjusted to form a gradient habitat, which meets the different foraging water depth requirements of different types of water birds, further enriches the spatial level of the bird microhabitat, and improves the protection level of wetland biodiversity;

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