Description

Technical Field

[0001] This utility model relates to the field of water purification technology, and more specifically, to a modular ecological floating island structure for river water purification. Background Technology

[0002] Rivers, as vital carriers of water resource circulation, serve multiple functions including flood control and drainage, ecological conservation, and landscaping. However, with the advancement of industrialization and urbanization, large amounts of domestic sewage, industrial wastewater, and agricultural non-point source pollution are discharged into rivers, leading to eutrophication, excessive levels of organic pollutants, algal blooms, and black and odorous water bodies. This severely disrupts the ecological balance of rivers and impacts water resource utilization and the human living environment. Ecological floating island technology, as a low-cost and eco-friendly water purification method, purifies water by planting aquatic plants on the water surface. The plant roots absorb pollutants, and microorganisms degrade organic matter, thus achieving water purification. This technology has been widely applied in river management.

[0003] However, traditional ecological floating island structures have many limitations and cannot meet the needs of complex river management. First, they have low modularity. Most traditional floating islands are monolithic structures that cannot be flexibly assembled according to the width and length of the river. This results in poor adaptability to rivers of varying widths and complex shapes, making transportation and deployment difficult. Some modular floating islands have cumbersome assembly structures and unstable connections, making them prone to separation due to water flow. Second, they lack flexibility in plant cultivation. The planting areas on traditional floating islands are fixed, making it impossible to adjust plant positions according to the river's sunlight distribution and water flow speed. This leads to some plants growing poorly due to insufficient sunlight or strong water flow, affecting the purification effect. At the same time, the plant cultivation structure lacks protection, making the roots susceptible to being eaten by fish and entangled by debris. Furthermore, some cultivation components easily sink to the bottom after falling off, causing plant loss and interruption of the purification function.

[0004] Therefore, a modular ecological floating island structure for river water purification is proposed to address the above problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a modular ecological floating island structure for river water purification. It is highly modular, flexible in adjustment, stable in protection, and has high purification efficiency, and is suitable for ecological management of various types of river water bodies.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A modular ecological floating island structure for river water purification includes a rectangular floating island unit module. Connectors are fixedly installed on both the left and right sides of the upper end of the floating island unit module. Multiple evenly distributed ecological attachment bases are suspended at the lower end of the floating island unit module. A pair of U-shaped slide rails are also fixedly installed on the upper end of the floating island unit module. At least two adjustable plant cultivation components are slidably installed between the pair of U-shaped slide rails.

[0010] Furthermore, the floating island unit module includes a rigid frame, a buoyancy tray fixedly installed at the lower end of the rigid frame, and a protective surface layer fixedly installed at the lower end of the buoyancy tray. The rigid frame serves as the frame foundation to provide rigid support, the buoyancy tray is used to provide buoyancy in the river, and the protective surface layer is used to protect the buoyancy tray from damage.

[0011] Furthermore, the connector includes a docking plate with two symmetrically distributed threaded holes. An anchoring ring is fixedly installed on the upper end of the docking plate. The threaded holes on the docking plate are used to dock adjacent floating island unit modules on the left and right sides to adapt to river channels of different widths. The anchoring ring is used to fix the anchor rope.

[0012] Furthermore, a magnetic layer is fixedly installed on the inner wall of the U-shaped slide rail. The adjustable plant cultivation component includes a plant cultivation basket. A matching magnetic slider is slidably installed inside the U-shaped slide rail. The plant cultivation basket is fixedly installed between the magnetic slider and the connecting plate. The magnetic slider can slide and adjust the position of the plant cultivation basket inside the U-shaped slide rail to meet different plant growth needs. It is fixed in any position by relying on the magnetic attraction effect of the magnetic layer, making it easy to adjust and providing a certain degree of stability.

[0013] Furthermore, the plant cultivation basket includes a transparent cultivation tube, with a supporting floating ring fixedly installed at the lower end of the transparent cultivation tube, and an intercepting net sleeve fixedly installed at the lower end of the supporting floating ring. The transparent cultivation tube is used to protect the plant and allow light to pass through. The supporting floating ring is used to support the plant and allow the roots to extend into the river channel below. Even if the adjustable plant cultivation component falls into the river channel after detaching from the U-shaped slide rail, it can be suspended on the river channel by the buoyancy of the supporting floating ring and will not sink to the bottom and cause loss. The intercepting net sleeve allows water to pass through and can protect the plant roots.

[0014] Furthermore, anti-collision strips are fixedly installed at both ends of the rigid frame, and warning stickers are affixed to the outer surface of the anti-collision strips. The anti-collision strips are used to protect the rigid frame from impact damage, while the warning stickers can be used to serve as a warning on the river.

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) The modularity of the floating island structure in this solution is highly adaptable and can flexibly cope with different river scenarios. Traditional floating islands are mostly integral or cumbersome to splice, with poor adaptability. However, this structure can realize the rapid splicing of multiple floating island units through the anchoring rings and threaded holes of the connectors. It can be expanded freely in the horizontal and vertical directions, adapting to both narrow rivers and wide waters. It can be disassembled during transportation, reducing the difficulty of deployment. The anchor rope fixing design ensures that the floating island does not shift under the impact of water flow, further improving the adaptability to different hydrological environments.

[0018] (2) The plant cultivation in this scheme is flexible and the purification efficiency and stability are significantly improved. Traditional floating island plants are in fixed positions and are easily affected by unsuitable environments. However, the adjustable plant cultivation components in this structure can be flexibly adjusted according to light and water flow through the cooperation of magnetic sliders and U-shaped rails to ensure suitable plant growth. The supporting floating ring prevents the components from falling off and sinking to the bottom, and the intercepting net protects the root system, ensuring plant survival and continuous purification function. The transparent cultivation tube promotes photosynthesis, and the ecological attachment substrate provides a carrier for microorganisms, which greatly improves the water purification efficiency and the stability of the effect.

[0028] Example:

[0029] Please see Figure 1 - Figure 4 The modular ecological floating island structure for river water purification includes a rectangular floating island unit module 1. Connectors 2 are fixedly installed on both the left and right sides of the upper end of the floating island unit module 1. Multiple evenly distributed ecological attachment bases 3 are suspended at the lower end of the floating island unit module 1. A pair of U-shaped slide rails 6 are also fixedly installed on the upper end of the floating island unit module 1. At least two adjustable plant cultivation components 7 are slidably installed between the pair of U-shaped slide rails 6.

[0030] The floating island unit module 1 includes a rigid frame 11, a buoyancy tray 12 is fixedly installed at the lower end of the rigid frame 11, and a protective surface layer 13 is fixedly installed at the lower end of the buoyancy tray 12. The rigid frame 11 provides rigid support as the frame foundation, the buoyancy tray 12 is used to provide buoyancy on the river, and the protective surface layer 13 is used to protect the buoyancy tray 12 from damage. The ecological attachment base 3 can be made of artificial fiber aquatic plants or biological rope.

[0031] The rigid frame 11 is made of stainless steel through welding and has a corrosion-resistant surface treatment. It possesses both high strength and corrosion resistance, resisting the damp erosion and water flow impact of the river, providing stable and rigid support for the overall structure and preventing deformation. The buoyancy tray 12, fixed to the lower end of the rigid frame 11, is made of high-density polyethylene (HDPE) through injection molding. This material has strong buoyancy, is water-resistant and aging-resistant, and is non-toxic and environmentally friendly, preventing water pollution. The tray has a hollow structure, further enhancing buoyancy and ensuring the floating island unit floats stably on the water surface. The protective surface layer 13 at the lower end of the buoyancy tray 12 is made of wear-resistant rubber or modified polypropylene, with uniform thickness, and fits tightly to the bottom of the buoyancy tray 12. It effectively resists scratches from sand and gravel and sharp debris at the bottom of the river, as well as wear from water flow impact, extending the service life of the buoyancy tray 12.

[0032] The connector 2 includes a docking plate 21 with two symmetrically distributed threaded holes 23. An anchoring ring 22 is fixedly installed on the upper end of the docking plate 21. The threaded holes 23 on the docking plate 21 are used to dock adjacent floating island unit modules 1 on the left and right sides and are fixed by bolt and nut pairs to adapt to river channels of different widths. The anchoring ring 22 is used to fix the anchor rope and anchor the spliced ​​floating island structure in the designated area of ​​the river channel to prevent it from being washed away or displaced by the water flow.

[0033] A magnetic layer 8 is fixedly installed on the inner wall of the U-shaped slide rail 6. The adjustable plant cultivation component 7 includes a plant cultivation basket 71. A matching magnetic slider 73 is slidably installed inside the U-shaped slide rail 6. The plant cultivation basket 71 is fixedly installed between the magnetic slider 73 and the connecting plate 72. The magnetic slider 73 can slide and adjust the position of the plant cultivation basket 71 inside the U-shaped slide rail 6 to meet different plant growth needs. It is fixed in any position by relying on the magnetic attraction effect with the magnetic layer 8, which is convenient to adjust and has a certain degree of stability.

[0034] The plant cultivation basket 71 includes a transparent cultivation tube 711, a supporting floating ring 712 is fixedly installed at the lower end of the transparent cultivation tube 711, and an intercepting net sleeve 713 is fixedly installed at the lower end of the supporting floating ring 712.

[0035] The transparent cultivation tube 711 is made of PC endurance board through hot bending, which has high light transmittance, ensuring sunlight penetration for plant photosynthesis. It also possesses impact resistance and UV aging resistance, making it less prone to breakage. The supporting floating ring 712 at the bottom of the transparent cultivation tube 711 is injection molded from HDPE material, providing ample buoyancy. It not only supports the plant itself but also provides growth space for the plant roots, allowing them to naturally extend into the river water below. Even if the adjustable plant cultivation component 7 accidentally detaches from the U-shaped slide rail 6, the supporting floating ring 712 can use its own buoyancy to keep the entire component suspended on the water surface, preventing it from sinking and ensuring the survival of the cultivated plants and maintaining the purification function. The intercepting net sleeve 713 fixed at the bottom of the supporting floating ring 712 is made of nylon mesh with mesh sizes adapted to plant root growth. It allows river water to pass freely, providing sufficient oxygen and nutrients to the plant roots, while blocking debris and fish from grazing on the roots, effectively protecting them. The magnetic slider 73 is made of neodymium iron boron permanent magnet wrapped in a plastic shell. It is magnetically stable and tightly attracted to the magnetic layer 8 of the U-shaped slide rail 6. The magnetic slider 73 is fixed to the connecting plate 72 by bolts. The connecting plate 72 is welded or injection molded to the plant cultivation basket 71 to ensure the overall structure is stable. When sliding and adjusting, it drives the plant cultivation basket 71 to move synchronously. It can be fixed at any position by magnetic attraction, making adjustment convenient and not easy to move.

[0036] Both ends of the rigid frame 11 are fixedly equipped with anti-collision strips 4. Warning stickers 5 are affixed to the outer surface of the anti-collision strips 4. The anti-collision strips 4 are made of wear-resistant rubber material and are molded. They are soft and have excellent elasticity, which can buffer the impact force of ships and floating objects on the floating island structure and prevent damage to the rigid frame. The warning stickers 5 affixed to the outer surface of the anti-collision strips 4 are made of reflective material. They can reflect light even on cloudy days or at night to remind passing ships to pay attention and avoid collisions.

[0037] Working principle:

[0038] The first step is modular assembly and positioning: Based on the required width and length of the river channel to be treated, several floating island unit modules 1 are selected. The connecting parts 2 of adjacent floating island units are aligned, that is, the connecting plate 21 of one floating island unit is attached to the connecting plate of another floating island unit. Mechanical fixation is achieved by bolts passing through anchoring rings 22, completing the horizontal or vertical assembly between modules to form a floating island assembly adapted to the river channel dimensions. After assembly, anchor ropes are fixed using the threaded holes 23 on the connecting plates 21. The other end of the anchor rope is fixed to anchor piles on both banks of the river or a fixing device on the riverbed, stabilizing the floating island structure in the designated purification area and preventing displacement due to water flow impact.

[0039] The second step is the adjustment of the plant cultivation component and the planting of plants: The position of the adjustable plant cultivation component 7 is adjusted according to the river's light distribution, water flow speed, and the growth requirements of different aquatic plants. The operator manually pushes the plant cultivation basket 71, causing the magnetic slider 73 to slide along the U-shaped rail 6. The magnetic slider 73 and the magnetic layer 8 inside the U-shaped rail 6 are attracted in real time, ensuring a smooth and uninterrupted sliding process. Once adjusted to the target position, the attraction between the magnetic layer 8 and the magnetic slider 73 fixes the component in place, eliminating the need for additional locking structures, making it both convenient and stable. Subsequently, planting substrates such as expanded clay pebbles or volcanic rock are filled into the transparent cultivation tube 711, and aquatic plants with water purification functions, such as reeds, calamus, and canna lilies, are planted. The plant roots pass through the supporting floating ring 712 and extend through the mesh of the intercepting net sleeve 713 into the river water below, completing the plant cultivation.

[0040] The third step is synergistic water purification: After the floating islands are put into use, aquatic plants absorb nutrients such as nitrogen and phosphorus from the river water through their roots, reducing eutrophication. At the same time, a biofilm forms on the root surface, adsorbing suspended particulate matter in the water. The ecological attachment substrate 3 suspended at the lower end of the floating island unit module 1 provides ample attachment carriers for microorganisms. Microorganisms reproduce and grow on the surface of the attachment substrate, decomposing organic pollutants in the water, achieving a synergistic purification effect of "plant absorption + microbial degradation". The transparent cultivation tube 711 allows sunlight to penetrate fully, ensuring plant photosynthesis and promoting plant growth and enhanced purification capacity. The buoyancy of the supporting floating ring 712 keeps the plants at a suitable water level, and the intercepting net 713 prevents root damage, ensuring a continuous and stable purification process.

[0041] Fourth, safety protection and warnings: During the use of the floating island, the anti-collision strips 4 at both ends of the rigid frame 11 are always in a protective state. When a ship approaches or a floating object impacts, the rubber anti-collision strips buffer the impact force through elastic deformation, protecting the rigid frame and buoyancy tray 12 from damage. The reflective warning stickers 5 on the surface of the anti-collision strips reflect light under illumination, reminding passing ships to avoid collisions that could damage the floating island structure or plants. In extreme cases where the adjustable plant cultivation component falls off, the buoyancy of the supporting floating ring 712 can keep the component suspended on the water surface, allowing operators to easily retrieve and reinstall it, preventing plant loss and water pollution.

[0042] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
