Description

Technical Field

[0001] This utility model relates to the field of water ecological restoration technology, specifically to an ecological enclosure with purification function. Background Technology

[0002] In the field of aquatic ecological restoration, enclosure is a commonly used method of separating water areas. Through physical isolation, it can reduce the spread of pollution, block algae and control turbidity, intercept herbivorous fish, provide a low-disturbance environment inside the enclosure, and lay the foundation for the creation of habitats inside the enclosure. It is one of the key means in aquatic ecological restoration.

[0003] Currently used traditional enclosures have weak resistance to wind and waves, are prone to displacement and damage under strong water flow, and are unsightly. They are simply physical isolation methods without ecological purification and regulation functions. Algae and some pollutants often adhere to the outside of the enclosure, resulting in a poor appearance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an ecological enclosure with a purification function, so as to overcome the shortcomings of the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An ecological enclosure with purification function includes: a reinforcing strip, steel pipes, and ecological floating islands. Multiple steel pipes are distributed along the length of the reinforcing strip and alternately located on both sides of the reinforcing strip. The wall thickness of the steel pipes is ≥4mm. The lower end of the steel pipes is inserted into a stable stratum at the bottom of the lake to a depth of ≥3m, and the upper end of the steel pipes is above the flood level. The lower end of the reinforcing strip is connected to a fabric skirt, and the lower end of the fabric skirt is connected to a gabion at the bottom of the lake. Two through holes are opened between two adjacent steel pipes in the reinforcing strip. An ecological floating island is placed between two adjacent steel pipes. Part of each ecological floating island is located on one side of the reinforcing strip, and the other part of the ecological floating island passes through the two through holes and is located on the other side of the reinforcing strip. The reinforcing strip and the steel pipes are connected by connectors. Aquatic plants are planted on the ecological floating islands.

[0006] The beneficial effects of this utility model are: it provides physical isolation while simultaneously synergistically purifying and regulating the environment. The enclosure effectively blocks external pollutants, algae, and herbivorous fish, while aquatic plants absorb heavy metals and nutrients. Root-attached microorganisms enhance degradation, and the model also provides landscape value. By placing the ecological floating island on both sides of the reinforcing zone, it disperses wave stress, resists wind and wave impacts, and adapts to water level changes in a timely manner. It has a strong ability to change with the water level and can effectively separate water areas to establish functional ecological zones. It has the functions of guiding flow, blocking algae, and purifying water, while also providing excellent landscape effects. This invention solves the problems of traditional enclosures, such as weak resistance to wind and wave impacts, easy damage during large waves, untimely water level regulation, and the inability to purify water simply by separating it. This utility model directly addresses the three major challenges in aquatic ecological restoration: "difficulty in controlling algae, weak purification, and poor adaptability," providing an integrated solution for aquatic ecological restoration that combines physical protection and ecological regulation.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the steel pipes are galvanized steel pipes with a diameter of DN65mm to DN100mm, the spacing between two adjacent steel pipes is 5m to 8m, and the upper end of the steel pipe is 1m above the flood level.

[0009] The further beneficial effects mentioned above are: the galvanized steel pipe has sufficient strength and rigidity, and the upper end of the steel pipe is 1m above the flood level, which can effectively resist the attack of wind and waves with a wave height of 1m.

[0010] Furthermore, the reinforcing strip is made of polyester, with a tensile strength ≥5t and a thickness ≥6mm; the overlap width between the reinforcing strip and the skirt body is ≥4mm.

[0011] Based on the above, the further beneficial effects are as follows: the reinforcing belt is made of polyester with a tensile strength of ≥5t and a thickness of ≥6mm, ensuring that it can effectively bear the load under the impact of wind, waves, water flow, or unexpected loads, maintaining the overall shape and stability of the enclosure. The overlap width between the reinforcing belt and the fabric skirt is ≥4mm, which can ensure the connection strength and prevent it from coming apart under stress.

[0012] Furthermore, the skirt body uses nylon fabric as the base frame, with waterproof coated polyester fabric attached to the outside of the nylon fabric. The total length H of the skirt body in the height direction is the difference between the normal water level and the lake bottom elevation + the flood season water level rise value + 0.5m.

[0013] The further beneficial effects mentioned above are as follows: the base skeleton provides the main tensile strength and tear resistance, forming the "skeleton" of the skirt, ensuring that it can effectively unfold in water and resist external stretching. The nylon fabric is covered with a waterproof coated polyester fabric. The main function of the waterproof coated polyester fabric is to provide excellent waterproof sealing and resistance to environmental erosion (UV resistance, water immersion resistance, and microbial erosion resistance). The coating layer in the waterproof coated polyester fabric further enhances the water-blocking effect, prevents water penetration, and protects the internal base skeleton from damage. The skirt can freely expand and contract when the water level rises during the flood season.

[0014] Furthermore, the gabion includes: a mesh bag and stones filled inside the mesh bag, the stones being 10mm to 20mm of crushed stone, boulders, pebbles or concrete blocks, and the mesh bag including: nylon fabric and waterproof coated polyester fabric attached to the nylon fabric.

[0015] Based on the above, the further beneficial effects are as follows: the mesh bag has a double-layer structure design, which combines the high strength and abrasion resistance of nylon with the excellent waterproof and corrosion-resistant properties of coated polyester fabric, effectively preventing the loss of filler and extending its service life.

[0016] Furthermore, the ecological floating island includes: pontoons and floating island panels. The pontoons are U-shaped, with one part of the pontoon located on one side of the reinforcing strip and the other part of the pontoon passing through two holes and located on the other side of the reinforcing strip. Multiple floating island panels are arranged on both sides of the reinforcing strip within the area enclosed by the pontoons. The floating island panels on the outer perimeter are connected to the pontoons by hoops, and four adjacent floating island panels on the same side of the reinforcing strip are connected by plate buckles. Planting baskets are arranged in the planting holes on the floating island panels, and aquatic plants are planted on the planting substrate contained in the planting baskets.

[0017] The further beneficial effect of the above is that it allows part of the ecological floating island to be on one side of the reinforcing strip, and the other part to be on the other side of the reinforcing strip after passing through two holes.

[0018] Furthermore, multiple holes are made in the area between two adjacent through holes and corresponding to the buoys on the reinforcing strip, and adjacent floating island plates on both sides of the reinforcing strip are connected by hoops passing through the holes.

[0019] The further beneficial effect of the above is that it allows the ecological floating island to withstand possible lateral forces or water flow impacts, ensuring the integrity of the structure.

[0020] Furthermore, the pontoon is made of multiple PE pipes heat-fused together in a U-shape, with the outer diameter of the PE pipes being 100mm.

[0021] Furthermore, the aquatic plants include canna lilies, umbrella sedges, thaliana, or irises.

[0022] Based on the above, the further beneficial effects are as follows: it can directly absorb and utilize eutrophic substances in the water through its root system, inhibit excessive algal growth (algal bloom), and improve water transparency. At the same time, its vast underwater root system provides a huge surface area (biofilm carrier) for microorganisms (bacteria, fungi, etc.), and the organic substances secreted by the plant roots (such as sugars, organic acids, enzymes, etc.) can stimulate and promote the growth and activity of microorganisms, thereby significantly enhancing the biodegradation and transformation capacity of organic pollutants and even some heavy metals in the water. In addition, the bright flowers of canna lilies, the umbrella-shaped leaves of umbrella foliage, the upright plant posture of canna lilies, and the elegant flowers and leaves of irises not only have significant purification functions, but also form a water garden with rich layers and seasonal changes, greatly enhancing the landscape effect and ecological beauty of the water area, and achieving the unity of environmental governance and ecological aesthetics.

[0023] Furthermore, the connector includes a first ring, a second ring, and a nylon rope. The first ring is fixed to the reinforcing belt, the second ring is connected to the first ring, and the nylon rope passes around the second ring and two through holes on both sides of the steel pipe to form a double flexible connection with the steel pipe.

[0024] The further beneficial effects mentioned above are as follows: using high-strength, weather-resistant, flexible, and water-resistant nylon ropes for double-layer flexible connections can limit the lateral displacement of the reinforcing belt and the ecological floating island, maintain the basic stability of the relative positions between the devices, and allow them to float freely in the vertical direction with the rise and fall of the water level, thus avoiding structural damage caused by rigid constraints due to water level changes.

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] Example 1 like Figures 1-4 As shown, an ecological barrier with a purifying effect includes: The structure consists of a reinforcing strip 1, steel pipes 2, and an ecological floating island 3. Multiple steel pipes 2 are distributed along the length of the reinforcing strip 1 and are alternately located on both sides of the reinforcing strip 1. To ensure the overall stability and structural strength of the ecological enclosure, the steel pipes 2 serve as the core supporting components. To provide the necessary structural strength and rigidity to resist water pressure, wind waves, and external forces, the wall thickness of the steel pipes 2 is ≥4mm. The lower end of steel pipe 2 is inserted into the stable stratum at the bottom of the lake to a depth of ≥3m, which can obtain sufficient anchoring force to prevent steel pipe 2 from being pulled up or tilted under the action of water; the upper end of steel pipe 2 is higher than the flood level. The lower end of the reinforcing belt 1 is connected to the skirt body 4. The reinforcing belt 1 and the skirt body 4 work together to achieve the function of an underwater isolation barrier. The lower end of the skirt body 4 is connected to the gabion 5 located at the bottom of the lake, so that the skirt body 4 can effectively contact the bottom of the lake. When the water level rises during the flood season, the skirt body 4 can freely expand and contract. Two through holes 110 are made between two adjacent steel pipes 2 on the reinforcing strip 1. An ecological floating island 3 is placed between two adjacent steel pipes 2. Part of each ecological floating island 3 is located on one side of the reinforcing strip 1, and the other part passes through the two through holes 110 and is located on the other side of the reinforcing strip 1. The reinforcing strip 1 and the steel pipes 2 are connected by connectors 6. Aquatic plants 7 are planted on the ecological floating islands 3. The aquatic plants 7 can efficiently absorb nitrogen and phosphorus, inhibit algae growth, and promote the degradation of pollutants by microorganisms through secretions, and also have a certain landscape effect.

[0029] Example 2 like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on embodiment 1, as detailed below: Steel pipe 2 is made of galvanized steel pipe with a diameter of DN65mm to DN100mm, which has sufficient strength and rigidity. The distance between two adjacent steel pipes 2 is 5m to 8m. The upper end of steel pipe 2 is 1m above the flood level, which can effectively resist the attack of wind and waves with a wave height of 1m.

[0030] Example 3 like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment is a further improvement on embodiment 1 or 2, as detailed below: The reinforcing strip 1 is made of polyester with a tensile strength of ≥5t and a thickness of ≥6mm. It is designed to effectively bear the load under the impact of wind, waves, water flow, or unexpected loads, and maintain the overall shape and stability of the enclosure. The overlap width between the reinforcing strip 1 and the fabric skirt 4 is ≥4mm, which can ensure the connection strength and prevent separation under stress. The reinforcing strip 1 and the fabric skirt 4 can be connected by sewing or other reliable methods. As a key area for stress transmission, it is necessary to ensure that the sewing stitches or adhesive strength are sufficient to withstand the design load.

[0031] Example 4 like Figure 2 , Figure 3 As shown, this embodiment is a further improvement on any one of embodiments 1 to 3, as detailed below: The skirt 4 uses nylon fabric as the base skeleton, providing the main tensile strength and tear resistance, forming the "skeleton" of the skirt 4, ensuring that it can effectively unfold in water and resist external stretching. The nylon fabric is covered with waterproof coated polyester fabric. The main function of the waterproof coated polyester fabric is to provide excellent waterproof sealing and resistance to environmental erosion (UV resistance, water immersion resistance, and microbial erosion resistance). The coating layer in the waterproof coated polyester fabric further enhances the water-blocking effect, prevents water penetration, and protects the internal base skeleton from damage. The total length H of the skirt 4 in the height direction must ensure that it can freely stretch and unfold upwards when the water level rises during the flood season, without being stretched taut or generating excessive stress. Therefore, the length H is the difference between the normal water level and the lake bottom elevation + the flood season water level rise value + 0.5m, allowing it to freely expand and contract when the water level rises during the flood season.

[0032] Example 5 like Figure 2 , Figure 3 As shown, this embodiment is a further improvement on any one of embodiments 1 to 4, as detailed below: Gabion 5 includes: a mesh bag and stones filled inside the mesh bag. The stones are 10mm-20mm boulders, pebbles, or concrete blocks. The mesh bag includes: nylon fabric and waterproof coated polyester fabric attached to the nylon fabric. This type of mesh bag has a double-layer structure design, combining the high strength and abrasion resistance of nylon with the excellent waterproof and corrosion-resistant properties of coated polyester fabric, effectively preventing the loss of filler and extending service life. The outer diameter of gabion 5 is 100mm-200mm. The stones should be put in from the opening of the mesh bag. After the stones are filled, the opening of the mesh bag should be tightened with steel wire to prevent the filler from leaking under the impact of water flow. When the supply of crushed stone is limited, other prefabricated counterweight blocks that meet the counterweight requirements can also be selected. When the filling material is boulders, pebbles, or concrete blocks, it should meet the requirements of good durability, not being easily broken, and having no signs of weathering to ensure the stable function of the gabion in the long-term underwater environment.

[0033] Example 6 like Figure 1 , Figure 3 , Figure 4 As shown, this embodiment is a further improvement on any one of embodiments 1 to 5, as detailed below: The ecological floating island 3 includes: a pontoon 310 and a floating island plate 320. The pontoon 310 is U-shaped, with one part of the pontoon 310 located on one side of the reinforcing band 1, and the other part of the pontoon 310 passing through two through holes 110 and located on the other side of the reinforcing band 1. Multiple floating island plates 320 are respectively arranged on both sides of the reinforcing band 1 within the area enclosed by the pontoon 310. The floating island plate 320 serves as the supporting base of the ecological floating island 3 and is preferably made of HDPE material, which can float stably on the water surface for a long time and resist the erosion of the aquatic environment. The individual size can be length × width × thickness: 330mm × 330mm × 40mm, which is a regular square unit. The outer floating island plate 320 is connected to the buoy 310 via a hoop 330, forming the overall frame and edge support of the floating island. The hoop 330 can be made of stainless steel. The four adjacent floating island plates 320 on the same side of the reinforcing strip 1 are connected by a plate buckle 340. That is, the plate buckle 340 is X-shaped and corresponds to the pre-reserved holes on the floating island plate 320. One plate buckle 340 can tightly and conveniently splice and combine four floating island plates 320 to form a larger floating island platform, enhancing the stability and load-bearing capacity of the overall structure. Planting baskets 350 are arranged in the planting holes on the floating island plate 320. Aquatic plants 7 are planted in the planting substrate contained in the planting baskets 350. The planting baskets 350 can be made of durable plastic weaving or injection molding, with a water-permeable and air-permeable mesh structure to hold the planting substrate, stabilize the roots of the aquatic plants 7, and allow the plant roots to freely extend and penetrate into the water to absorb nutrients, and promote the exchange of substances between the water and the rhizosphere microbial zone.

[0034] Example 7 like Figures 1-4 As shown, this embodiment is a further improvement on embodiment 6, as detailed below: Multiple holes 120 are made on the reinforcing strip 1 between two adjacent through holes 110 and in the area corresponding to the float 310. The adjacent floating island plates 320 on both sides of the reinforcing strip 1 are connected by hoops 330 passing through the holes 120, so that the ecological floating island 3 can withstand possible lateral forces or water flow impacts and ensure the integrity of the structure.

[0035] The float 310 is made of multiple PE pipes heat-fused together in a U-shape. The outer diameter of the PE pipes is 100mm. Of course, the size of the PE pipes is at least an exemplary distance here. In actual use, other sizes, such as 90mm, 110mm, etc., are not excluded.

[0036] Example 8 like Figure 3As shown, this embodiment is a further improvement on embodiment 6 or 7, as detailed below: The aquatic plants 7 are canna lilies, umbrella sedges, thaliana, or irises. They can directly absorb and utilize eutrophic substances in the water through their roots, inhibiting excessive algal blooms and improving water transparency. At the same time, their extensive underwater root systems provide a huge surface area (biofilm carrier) for microorganisms (bacteria, fungi, etc.), and the organic substances secreted by the plant roots (such as sugars, organic acids, enzymes, etc.) can stimulate and promote the growth and activity of microorganisms, thereby significantly enhancing the biodegradation and transformation capacity of organic pollutants and even some heavy metals in the water. In addition, the bright flowers of canna lilies, the umbrella-shaped leaves of umbrella sedges, the upright posture of thaliana, and the elegant flowers and leaves of irises not only have significant purification functions, but also form a water garden with rich layers and seasonal changes, greatly enhancing the landscape effect and ecological beauty of the water area, and achieving the unity of environmental governance and ecological aesthetics. Only one type of aquatic plant 7 is planted in each planting basket 350, and only one planting basket 350 is placed in each planting hole on each floating island 320.

[0037] Example 9 like Figure 2 , Figure 3 As shown, this embodiment is a further improvement on any one of embodiments 1 to 8, as detailed below: The connector 6 includes a first ring 610, a second ring 620, and a nylon rope 630. The first ring 610 is fixed on the reinforcing belt 1. The second ring 620 is connected to the first ring 610. The nylon rope 630 passes around the second ring 620 and the two through holes 110 on both sides of the steel pipe 2 and then forms a double-layer flexible connection with the steel pipe 2. The double-layer flexible connection uses a nylon rope 630 with high strength, good weather resistance, good flexibility, and water resistance to limit the lateral displacement of the reinforcing belt 1 and the ecological floating island 3, maintain the basic stability of the relative position between the devices, and allow them to float freely in the vertical direction with the rise and fall of the water level, avoiding structural damage caused by rigid constraints due to water level changes. The outer diameter of the nylon rope 630 is ≥6mm.

[0038] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
