Description

Technical Field

[0001] The present invention relates to the technical field of ecological floating islands, in particular to a method for an ecological floating island to adapt to a high-velocity river channel. Background Art

[0002] Ecological floating islands, also known as artificial floating beds or eco-floating beds, are a type of artificial floating island that targets eutrophic water quality by utilizing eco-engineering principles to degrade COD, nitrogen, and phosphorus. They utilize aquatic plants, employ soilless cultivation techniques, and polymer materials as carriers and matrices. They leverage interspecies symbiosis and fully utilize the spatial and nutrient niches of the water body to create a highly efficient artificial ecosystem that reduces the pollution load in the water. They significantly improve water clarity and water quality, particularly suppressing algae. The primary water purification benefit of ecological floating islands is the absorption of nutrients such as total phosphorus, ammonia nitrogen, and organic matter by the plant roots, thereby transferring nutrients from the water and reducing the odor and eutrophication caused by closed or insufficiently self-circulating water bodies.

[0003] Currently, traditional ecological floating islands are widely used in river management, but they are primarily used for water purification in low-velocity or stagnant water bodies. In rivers with large velocity fluctuations or high-velocity flows, these islands are unable to withstand the impact of currents and are largely unusable. Patent application CN110294532A, entitled "A Floating Island with High Impact Resistance," discloses a structure that adds a sewage interception wall and a diversion wall in front of the downstream impact end of the floating island. While this structure effectively blocks water impact, it also creates a dead zone around the floating island, reducing its effectiveness. This solution is not optimal for addressing the problem of ecological floating islands' suitability for high-velocity rivers. Therefore, a method for adapting ecological floating islands to high-velocity rivers is urgently needed to address this issue. Summary of the Invention

[0004] The purpose of the present invention is to provide a method for making an ecological floating island adapt to a high-velocity river channel, so as to solve the problem that the existing floating island is not suitable for a high-velocity river channel.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for adapting an ecological floating island to a high-velocity river, comprising the following:

[0006] The main body of the ecological floating island is set up along the river slope, and the front blocking enclosure, side blocking enclosure and roundabout water diversion enclosure are arranged around the main body of the ecological floating island; the two ends of the three are respectively provided with fixed poles with the lower end inserted into the bottom of the river;

[0007] The front barrier is set in the direction of the water flow from the main body of the ecological floating island, and the distance from the end close to the river slope to the center of the river is greater than the distance from the main body of the ecological floating island to the center of the river, which is used to block part of the frontal water impact;

[0008] The side barrier is set on the side of the ecological floating island away from the river slope to block the impact of side water;

[0009] There is a gap between the end of the front blocking enclosure away from the river bank and the side blocking enclosure, one end of the detour water diversion enclosure is placed close to the side blocking enclosure, and the other end is extended to between the front blocking enclosure and the main body of the ecological floating island to block the impact of another part of the frontal water, and there is a gap between the end of the front blocking enclosure away from the river bank and the detour water diversion enclosure, so that the water flow is slowed down and flows along the gap to the area where the main body of the ecological floating island is located.

[0010] Preferably, the front blocking enclosure, the side blocking enclosure and the roundabout water diversion enclosure are all made of waterproof flexible materials, a float is fixedly provided at the upper end of the flexible material, a counterweight is fixedly provided at the lower end, a movable ring is fixedly provided on one side of the float, and the movable ring is mounted on the fixed rod and slidably connected to it; it is used to allow the flexible material to move up and down along the fixed rod following the water level.

[0011] Preferably, the fixing rod is a T-shaped tube, the upper end of which is higher than the water level of the river during flood season.

[0012] Preferably, the side blocking enclosure is arranged parallel to the direction of water flow; the angle between the front blocking enclosure and the water flow direction on the water flow side is an obtuse angle not greater than 150°, and the angle between the roundabout water diversion enclosure and the side blocking enclosure on the water flow side is a right angle or an obtuse angle not greater than 135°.

[0013] Preferably, a support rod is fixed to the back surface of the fixing rod, the lower end of the support rod is obliquely inserted into the bottom of the river channel, and a fixing piece is provided at the upper end for supporting the fixing rod.

[0014] Preferably, the main body of the ecological floating island includes a floating island frame, a floating island base and multiple T-shaped rods inserted into the bottom of the river channel. A plurality of rings are fixed around the floating island frame for being mounted on each rod. The floating island frame is made of a material with a density lower than that of water, and its height rises and falls along the rods as the water level changes. The floating island base is a hollow structure with a density lower than that of water. It is fixed on all sides within the floating island frame, and aquatic plants are planted in the hollow structure. An elastic biological filler suspended in the water is fixed at the lower end of the floating island base.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The ecological floating island adapts to high-velocity rivers by setting up enclosures in the direction of water inflow and on the side facing the center of the river. This can effectively block the direct impact of high-velocity water on the roots of aquatic plants and elastic biological fillers in the floating island, thereby protecting the formation and development of the root system and biofilm structure, protecting the floating island from being easily destroyed, and effectively reducing the cost of river operation and maintenance.

[0017] 2. The ecological floating island adapts to high-speed river channels by not completely blocking the flow of water through the floating island. Instead, it isolates the impact of side water flow and slows down the frontal water flow through the floating island in a circuitous way, avoiding the formation of dead water areas around the floating island. This reduces the impact while ensuring the proper water management effect of the floating island.

[0018] 3. The ecological floating island adapts to high-flow rivers. The height of the enclosure and the floating island can move up and down along the fixed poles and rods as the water surface changes, thereby adapting to changes in river water levels and reducing the difficulty of operation and maintenance.

[0022] A method for adapting an ecological floating island to a high-velocity river includes the following:

[0023] like Figure 1 As shown, the main body of the ecological floating island is set along the river bank 1, and the front blocking enclosure 3, the side blocking enclosure 4, and the roundabout water diversion enclosure 41 are arranged around the main body of the ecological floating island. The ends of the three are respectively provided with fixing rods 2, the lower ends of which are inserted into the bottom of the river. In addition, to prevent water from flooding the main body of the ecological floating island, the fixing rods 2 can be designed as T-shaped tubes, and their upper ends are higher than the flood season water level of the river.

[0024] The front blocking enclosure 3 is set in the water direction of the main body of the ecological floating island, and the distance from its end close to the river slope 1 to the center of the river is greater than the distance from the main body of the ecological floating island to the center of the river, which is used to block part of the front water impact;

[0025] The side blocking enclosure 4 is set on the side of the ecological floating island body away from the river slope 1 to block the impact of side water;

[0026] There is a gap between the end of the front blocking enclosure 3 away from the river bank 1 and the side blocking enclosure 4. One end of the detour water diversion enclosure 41 is placed close to the side blocking enclosure 4, and the other end is extended to between the front blocking enclosure 3 and the main body of the ecological floating island to block the impact of another part of the frontal water. There is also a gap between the end of the front blocking enclosure 3 away from the river bank 1 and the detour water diversion enclosure 41, so that the water flow is slowed down and flows along the gap to the area where the main body of the ecological floating island is located.

[0027] In addition, the purpose of setting along the river bank 1 is mainly to facilitate installation and maintenance, and the water flow velocity is usually lower near the shore than in the center of the river. Therefore, setting along the river bank 1 is only a preferred recommended option, not a must. In theory, it can also be set at any position in the river. When it is not set along the river bank 1, a side blocking enclosure 4 can be symmetrically added to the side of the original river bank 1 as a substitute.

[0028] See Figure 2 In a preferred embodiment, the front blocking enclosure 3, the side blocking enclosure 4 and the detour water diversion enclosure 41 are all made of waterproof flexible materials, such as plastic cloth or PVC curtain, etc. The upper end of the flexible material can be further fixed with a float 9, and the lower end is fixed with a counterweight 10. The counterweight 10 can be a container wrapped with objects with a density greater than water, such as sand or fine pebbles, or also wrapped with flexible material. A movable ring is fixed on one side of the float 9, which is mounted on the fixed rod 2 and slidably connected to it; it is used to make the flexible material move up and down along the fixed rod 2 according to the water level.

[0029] For reference, the side blocking enclosure 4 should be set parallel to the water flow direction. Its main function is to prevent the lateral water flow from impacting the floating island. Being parallel to the water flow direction can effectively reduce the direct impact on the enclosure and extend its service life. The angle between the front blocking enclosure 3 and the water flow direction on the water flow side is an obtuse angle of no more than 150°. The obtuse angle can minimize the impact of the water flow on the enclosure as much as possible and can effectively ensure its service life. However, since this solution is to slow down the water flow and continue to lead it to the floating island, a too large angle will lose the effect of blocking the impact. However, the specific angle can be adjusted according to the situation. Adjustment, for example, if the water flow speed is slow, a larger angle can be used; the roundabout water diversion enclosure 41 has two functions. One is to supplement the impact of the incoming water in the gap between the front blocking enclosure 3 and the side blocking enclosure 4, and at the same time further reduce the water flow speed after being blocked by the front blocking enclosure 3; the other is to guide the decelerated water flow to flow into the area where the floating island is located in a zigzag shape, avoiding the formation of a dead water area, so that the floating island can play its due purification role. For reference, the angle between it and the side blocking enclosure 4 on the water flow side should be set to a right angle or an obtuse angle not greater than 135°.

[0030] In order to improve the stability of the fixing rod 2, a support rod 8 can be further fixed on the back water surface of the fixing rod 2. The lower end of the support rod 8 is obliquely inserted into the bottom of the river channel. For reference, the inclination angle can be 45°. The upper end of the support rod 8 is preferably provided with a fixing part 13 for supporting the fixing rod 2. The fixing part 13 can be a tubular sleeve arranged on the outer periphery of the fixing rod 2, or a tile-shaped arc plate, or a buckle form, or two plates are set at the ends of the support rod 8 on both sides of the fixing rod 2 and an axis is passed through to rotate and connect them, or even a bolt passing through the fixing rod 2 and the support rod 8, etc. Any existing means can be used as long as the support rod 8 can play a supporting role.

[0031] In addition, in an optional embodiment, the main body of the ecological floating island can adopt the following structure: it includes a floating island frame 6, a floating island base 7 and a plurality of T-shaped rods inserted into the bottom of the river channel, and a plurality of rings 5 are fixed around the floating island frame 6 for being mounted on each rod; the floating island frame 6 is made of a material with a density less than that of water, and its height rises and falls along the rod as the water level changes, and the floating island base 7 is a hollow structure with a density less than that of water, which is fixed inside the floating island frame 6 on all sides, and aquatic plants 11 are planted in the hollow structure, and a floating island base 7 is fixed at the lower end thereof. It is obvious at this time that in order to effectively play a role in blocking impact, the height of the front blocking enclosure 3, the side blocking enclosure 4 and the detour water diversion enclosure 41 of the present invention should not be less than the height from the upper end of the floating island base 7 to the lower end of the elastic biological filler 12; of course, the main body of the ecological floating island can also adopt any other common form. The above is only a preferred option, and its specific form does not affect the main method of the present invention, that is, to block the impact of the front and side water flows by enclosure, and at the same time allow the decelerated water to flow through the floating island in a detour.

[0032] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined by the claims.

[0033] Any matters not described in detail in the present invention are well-known technologies to those skilled in the art.
