Description

Technical Field

[0001] This invention relates to the field of ecological floating bed technology, and in particular to an ecological floating bed treatment device for aquaculture wastewater suitable for wetland environments. Background Technology

[0002] Aquaculture wastewater contains high concentrations of nitrogen and phosphorus, organic matter, uneaten feed and feces, and trace amounts of drugs / heavy metals. Wetlands, as common recipients of wastewater, are prone to eutrophication and biodiversity loss due to pollution overload. Traditional physical (sedimentation / filtration) and chemical (flocculation / disinfection) treatments have drawbacks such as high energy consumption, secondary pollution, and complex operation and maintenance. In contrast, ecological floating beds have become the preferred route for wetland wastewater treatment due to their advantages of low cost, in-situ remediation, and eco-friendliness.

[0003] Ecological floating beds are an engineered form of floating artificial wetlands. The core consists of a floating body, a planting substrate, aquatic plants, and a microbial film. They achieve purification through a three-pronged approach: plant roots absorb nutrients such as nitrogen and phosphorus; the substrate and root biofilm adsorb and degrade organic matter and heavy metals; and microorganisms enhance nitrogen and phosphorus removal through nitrification-denitrification and polyphosphate accumulation, while simultaneously increasing dissolved oxygen in the water and inhibiting algae blooms, thus combining water purification and ecological restoration functions.

[0004] Traditional floating beds often use spliced ​​plastic pipe frames or foam boards as a carrier, resulting in weak connections between units. Under the influence of wind, waves, and water currents, they are prone to overall displacement, structural deformation, and even collapse, not only causing the intended purification area to fail but also posing safety hazards to waterways and dams. Furthermore, traditional floating beds are mostly fixed, integrated designs, unable to be flexibly configured according to spatial differences in water depth and quality. Based on these issues, this invention proposes an ecological floating bed treatment device for aquaculture wastewater suitable for wetland environments. Summary of the Invention

[0012] The quick-connect female connector includes a female connector body, and the elastic insert is disposed within the female connector body. At the center of the female connector body, a friction buffer cavity, a buffer cavity, a spline groove cavity, and a travel limiting cavity are sequentially distributed from top to bottom. A flange is formed at the junction of the spline groove cavity and the travel limiting cavity. One end of the spring abuts against the spring seat, and the other end abuts against the flange. A yielding ring is disposed above the upper end face of the dynamic friction damping ring in the upper part of the friction buffer cavity. Below the yielding ring is a static friction damping ring that matches the dynamic friction damping ring. A static friction damping ring that matches the dynamic friction damping ring is disposed within the buffer cavity. An external spline that matches the internal spline is disposed on the inner sidewall of the spline groove cavity. A yielding block is disposed at the bottom of the travel limiting cavity.

[0040] like Figure 1-12 This invention illustrates an ecological floating bed treatment device for aquaculture wastewater suitable for wetland environments. It includes a buoyancy frame 1, with several piles 2 symmetrically installed at the bottom of the buoyancy frame 1. The bottom of each pile 2 is inserted into the water bottom. Several symmetrically distributed inclined anchor chains 3 are installed at an angle between the edge of the buoyancy frame 1 and the water bottom, providing dual three-dimensional fixed constraints for the floating bed. The symmetrically installed piles 2, inserted into the water bottom, form a vertical limit, while the inclined anchor chains 3, arranged at an angle between the edge of the buoyancy frame 1 and the water bottom, counteract the horizontal thrust generated by wind, waves, and water flow, preventing overall displacement, structural deformation, or even disintegration of the floating bed. This ensures the stability and effectiveness of the pre-set purification area while eliminating safety hazards to waterways and dams.

[0041] The buoyancy frame 1 is internally composed of several floating bed modules 5, on which emergent plants 4 are planted. Adjacent floating bed modules 5, as well as the buoyancy frame 1 and floating bed modules 5, are connected via quick-connect females 6 and quick-connect females 7. Quick-connect sliders 9 are respectively installed at the ends of the quick-connect females 6 and quick-connect females 7 away from each other. The quick-connect sliders 9 are slidably mounted on quick-connect slides 10, which are snapped onto the buoyancy frame 1 or floating bed modules 5. Relying on the mating cooperation of the quick-connect females 6 and quick-connect females 7, combined with the sliding connection structure of the quick-connect sliders 9 on the quick-connect slides 10, rapid assembly and disassembly and stable connection are achieved between adjacent floating bed modules 5 and between the buoyancy frame 1 and floating bed modules 5. This ensures the connection strength between modules and allows for flexible adjustment of the combination and layout of the floating bed modules 5 according to spatial differences in water depth and quality, breaking the application limitations of traditional fixed floating beds and improving the adaptability and flexibility of water purification.

[0042] The floating bed module 5 includes a bed body 501. The upper end of the bed body 501 has several outer cavities 502 arranged in a matrix. An inner cavity 503 is installed at the center of each outer cavity 502, providing a stable planting medium for emergent plants 4. Several ventilation holes are provided on the bottom and lower outer walls of both the outer cavities 502 and the inner cavity 503 to ensure aeration and water permeability for plant roots, promoting plant growth and improving water purification. Several fixing blocks 504 are equidistantly installed around the outer perimeter of the bed body 501. A connecting frame 505 is installed at the other end of each fixing block 504. The connecting frame 505 engages with the quick-connect slide 10, allowing the floating bed module 5 to quickly connect with the buoyancy frame 1 and other floating bed modules 5, ensuring the stability of the module connection and the flexibility of assembly and disassembly.

[0043] The inner cavity 503 is filled with a lightweight fixing substrate for securing the emergent plant 4, stabilizing its root system, providing support for plant growth, and ensuring the core function of water purification. Specifically, the lightweight fixing substrate can be lightweight expanded clay granules, expanded perlite, polyurethane foam blocks, coconut coir, or vermiculite. These substrates are lightweight, have high porosity, and are chemically stable, which can stabilize the root system of the emergent plant 4, ensure aeration and water permeability, and will not increase the load on the floating bed or pollute the water. The outer cavity 502 is filled with one or more combinations of physical filter materials, microbial attachment packing materials, slow-release denitrification packing materials, or root-inducing materials. The physical filter material filled in the outer cavity 502 is gravel or shell fragments; the microbial attachment packing material is biochar particles or porous expanded clay granules; the slow-release denitrification packing material is sulfur-limestone mixed particles or solid biodegradable polymer; and the root-inducing material is a loose fiber mesh or maintains a hollow structure. The material filled in the outer cavity 502 constructs a multi-level composite purification system, realizing the synergistic effect of physical interception, microbial degradation, and chemical denitrification, which greatly improves the purification efficiency and adaptability of the floating bed to water bodies, and solves the problem of traditional floating beds relying solely on plant purification and having a single function.

[0044] The quick-connect sub-base 7 includes an L-shaped block 701 mounted (or welded) to the quick-connect slider 9. A quick-connect body is mounted below the L-shaped block 701. From top to bottom, the quick-connect body comprises a connecting end 702, a first dynamic friction damping ring 703, a buffer section 704, a second dynamic friction damping ring 705, a spline section 706, a spring seat 707, and a conical head 709. A limiting groove 710 (groove length equal to the maximum stroke) is formed on the buffer section 704. An elastic insert 8 is slidably mounted within the limiting groove 710, and the elastic insert 8 is inserted into the limiting groove 710 to achieve limiting and locking. A first spring 708 is sleeved on the outer periphery of the conical head 709; an internal spline is mounted on the spline section 706.

[0045] The quick-connect female connector 6 includes a female connector body, and the elastic insert 8 is installed in the female connector body. A through hole is provided in the female connector body for the elastic insert 8 to move. At the center of the female connector body, a friction buffer cavity 601, a buffer cavity 604, a spline groove cavity 606, and a travel limiting cavity 608 are arranged sequentially from top to bottom. A flange 607 is formed at the junction of the spline groove cavity 606 and the travel limiting cavity 608. One end of the spring 708 abuts against the spring seat 707, and the other end abuts against the flange 607. A yield ring 602 is installed in the upper part of the friction buffer cavity 601, located above the upper end face of the dynamic friction damping ring 703. A static friction damping ring 603, matching the dynamic friction damping ring 703, is installed below the yield ring 602. A static friction damping ring 605, matching the dynamic friction damping ring 705, is installed in the buffer cavity 601. The inner wall of the spline groove cavity 606 is fitted with an external spline that matches the internal spline, allowing it to move up and down along the spline without rotating. A yield block 609 is installed at the bottom of the stroke limiting cavity 608. The yield ring 602 and the yield block 609 are made of a low yield point metal material.

[0046] The elastic insert 8 includes a limiting shaft 802. One end of the limiting shaft 802 is integrally formed with a limiting head 801 that matches the limiting groove 710, and the other end (threaded section) extends out of the female body and is fitted with a nut 805. A second spring 803 is sleeved on the limiting shaft 802. One end of the second spring 803 abuts against the shoulder end face of the limiting shaft 802, and the other end abuts against the pressure plate 804. The pressure plate 804 is mounted on the outer wall of the female body by screws 806, providing stable support for the second spring 803.

[0047] Specifically, the fast-connection process is as follows:

[0048] First, the conical head 709 of the quick-connect male connector 7 is aligned with the friction buffer cavity 601 of the quick-connect female connector 6 and inserted. The conical head 709 acts as a guide, so that the spline section 706 of the quick-connect male connector 7 gradually engages with the external spline of the spline groove cavity 606 of the female connector body. During the insertion process, the dynamic friction damping ring 703 and the static friction damping ring 603 come into contact and fit together, and the dynamic friction damping ring 705 and the static friction damping ring 605 fit together synchronously. The spring 708 is compressed between the spring seat 707 and the flange 607 as the conical head 709 goes deeper, forming a preload.

[0049] Subsequently, when the quick-connect connector 7 is inserted to the preset stroke, the limiting groove 710 moves to the corresponding position of the limiting head 801 of the elastic plug 8. During the movement, the limiting head 801 is squeezed, thereby squeezing the second spring 803. Then, the elastic force of the second spring 803 pushes the limiting shaft 802 to move, so that the limiting head 801 is locked into the limiting groove 710, limiting the axial displacement of the quick-connect connector 7 and completing the connection locking.

[0050] Subsequently, when the floating bed encounters wind, waves, or water currents, the tensile or thrust forces generated between the five floating bed modules will be transmitted to the quick-connect structure:

[0051] First, the axial force is initially buffered by the elastic deformation of spring 708, which offsets part of the impact force.

[0052] Second, the friction between dynamic friction damping ring 703 and static friction damping ring 603, and between dynamic friction damping ring 705 and static friction damping ring 605, can consume impact energy and reduce relative shaking between modules.

[0053] Third, when the external force exceeds the preset threshold, the compression of spring 708 reaches its limit, and the impact force is transmitted to the yield ring 602 and the yield block 609. The yield ring 602 and the yield block 609 undergo controllable plastic deformation, absorbing the strong external force through their own deformation, thus preventing rigid fracture of components such as spline meshing structure, quick-connect slider 9, and quick-connect slide 10. After the external force disappears, the basic connection can still be maintained by the limiting effect of the elastic plug 8, which facilitates subsequent maintenance and replacement.

[0054] Finally, during disassembly, by squeezing the nut 805 and pulling the limit shaft 802, the limit head 801 is disengaged from the limit groove 710, thus releasing the lock; then, the quick connector 7 is pulled outward to complete the disassembly.

[0055] The quick-connect slider 9 includes a slider body 901, and the upper and lower ends of the slider body 901 are equipped with a first engagement groove 902. The quick-connect slide block 10 includes a slide block body 1001, and the upper and lower ends of the slide block body 1001 are equipped with a second engagement groove 1002 that mates with the first engagement groove 902.

[0056] The bottom of the quick-connect slide 10 is integrally formed with a C-shaped groove 1003. Several rope outlets 1004 are provided at the bottom of the C-shaped groove 1003, forming a hollow structure. A rope head 11 is slidably installed within the C-shaped groove 1003, and a rope 12 is mounted on the rope head 11, extending from the rope outlets 1004. During normal system operation, the rope 12 maintains a certain degree of slack and does not participate in load-bearing. When the quick-connect structure fails unexpectedly, the rope 12 will be straightened and tightened to prevent the floating bed module 5 from drifting away and to provide an interface for emergency rescue.

[0057] Specifically, the installation process is as follows:

[0058] First, align the first engagement groove 902 of the quick-connect slider 9 with the second engagement groove 1002 of the quick-connect slide block 10, allowing the slider body 901 to slide smoothly along the slide block body 1001. Then, attach the quick-connect slide block 10 to the connecting outer frame 505 of the buoyancy frame 1 or the floating bed module 5 via the C-shaped groove 1003, completing the basic installation. Next, slide the quick-connect slider 9 to move the quick-connect female seat 6 or quick-connect female seat 7 connected to it, adjusting it to the docking position with the corresponding module to ensure precise engagement between the quick-connect female seat 6 and the quick-connect female seat 7. Finally, place the rope end 11 into the C-shaped groove 1003 and slide it to the limit position corresponding to the quick-connect slider 9. Lead the rope 12 out from the rope outlet 1004 and pull and fix it appropriately, using the rope tension to limit the sliding of the quick-connect slider 9 and enhance the impact resistance of the connection structure.

[0059] The working process of this invention is as follows:

[0060] First, the buoyancy frame 1 is lowered to the target water area, and the symmetrically installed piles 2 at its bottom are inserted into the bottom of the water to complete the vertical fixation. Then, symmetrical inclined anchor chains 3 are laid between the edge of the buoyancy frame 1 and the bottom of the water to form a horizontal tension constraint. Then, the floating bed module 5 carrying emergent plants 4 is transported into the frame. The position is adjusted by sliding the quick-connect slider 9 on the quick-connect slide seat 10 so that the quick-connect female seat 6 and quick-connect female seat 7 between adjacent floating bed modules 5 and between floating bed modules 5 and buoyancy frame 1 are precisely connected to complete the overall assembly of the floating bed.

[0061] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
