Description

Technical Field

[0001] This utility model relates to the field of three-sided smooth river water treatment technology, specifically to a magnetic ecological floating island system applied to three-sided smooth river channels under slow-flow conditions. Background Technology

[0002] Three-sided concrete river channels (i.e., river channels where the riverbed and both banks are covered with concrete or hardened materials) are widely used in urban flood control, drainage, and land development projects. Their main functions are to enhance flood discharge capacity, prevent riverbank erosion, and reduce siltation. However, this highly engineered approach to river channel modification neglects the connection between the water body and the near-shore land, damaging the river's ecological functions, reducing its self-purification capacity, impairing its ecological restoration capabilities, and causing abnormal water temperature and dissolved oxygen (DO) concentrations, thus affecting the survival of aquatic organisms. With increasing ecological awareness, technologies for restoring the ecological functions of three-sided concrete river channels have received widespread attention. Currently, the application of technologies such as ecological floating islands, softened revetments, and artificial wetlands is promoting the reconstruction of a water-land-biological synergistic ecosystem in river channels. However, traditional ecological floating islands are fixed to the concrete banks of three-sided concrete river channels using anchoring methods. This anchoring method requires drilling holes in the concrete banks, which damages the concrete structure and makes maintenance difficult. Furthermore, the separation of flow guidance and purification functions, resulting in low efficiency, also limits the application of three-sided concrete river channels. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a magnetic ecological floating island system for use in three-sided smooth river channels under slow-flow conditions, so as to overcome the shortcomings of the above-mentioned prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A magnetic ecological floating island system for use in three-sided smooth river channels under slow-flow conditions includes: ecological floating islands arranged in the three-sided smooth river channel, each ecological floating island being attracted by a magnetic steel bar in one of the two concrete riverbanks of the three-sided smooth river channel via a magnet.

[0006] The beneficial effects of this utility model are as follows: When implementing this scheme, the location of the magnetic steel bar is first found in the concrete riverbank of the three-sided smooth river channel. Then, the ecological floating island is attracted to the magnetic steel bar in the concrete riverbank by a magnet. The ecological floating island is fixed to the concrete riverbank of the three-sided smooth river channel by magnetic attraction, so that the ecological floating island is fixed without damaging the concrete structure, that is, protecting the integrity of the concrete riverbank. This avoids the drilling construction of traditional anchoring methods, solves the problem of difficult installation of traditional ecological floating islands in three-sided smooth river channels under slow flow conditions (0.1m / s-0.3m / s), and reduces manual labor. The magnetic attraction fixing scheme allows for timely addition or removal of ecological floating islands during drought and flood seasons to avoid flood discharge problems caused by too many ecological floating islands during the flood season, which is flexible.

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

[0008] Furthermore, the floating bed in the ecological floating island is triangular in shape, and a magnet is provided on the bottom edge of the floating bed to attract the magnetic steel bars.

[0009] The further beneficial effect of adopting the above is that by designing the floating bed as a triangle, the floating bed forms a certain angle with the direction of water flow, thereby reducing the impact of water flow on the ecological floating island and preventing the ecological floating island from falling off.

[0010] Furthermore, each ecological floating island has rounded corners at the apex between the two sides of the floating bed.

[0011] The further beneficial effects of adopting the above are: the rounded corner design of the tip of the triangular floating bed reduces the damage to the structure caused by water flow impact and extends its service life.

[0012] Furthermore, the inclination angles of both sides of the floating bed are 30° to 60°.

[0013] The further beneficial effect of adopting the above is that this angle range can disperse the impact of water flow on the floating bed.

[0014] Furthermore, plants are grown on the floating beds in the ecological floating islands, and artificial aquatic plants are suspended below the floating beds.

[0015] The further beneficial effects of adopting the above methods are: while removing algae, microorganisms are enriched, breaking the monotony of hard waterways and enhancing aesthetics.

[0016] Furthermore, a guide plate is installed below the floating bed in the ecological floating island.

[0017] The further beneficial effect of adopting the above is that the guide plate under the floating bed can improve the disturbance of the water flow.

[0018] Furthermore, the artificial aquatic plants are modified artificial aquatic plants.

[0019] Furthermore, there are multiple ecological floating islands, arranged in two rows in a sawtooth pattern along the direction of water flow. Between the two rows of ecological floating islands is a central channel for water flow. One row of ecological floating islands is attracted to the magnetic steel bars in one of the two concrete riverbanks of the three-sided smooth river channel by magnets, and the other row of ecological floating islands is attracted to the magnetic steel bars in the other concrete riverbank by magnets.

[0020] The further beneficial effects of adopting the above are: this form can create slow-flow and turbulent flow zones, increasing the diffusion of oxygen and microorganisms in the water. In addition, floating objects are gathered in the concave area between the two ecological floating islands due to the action of water flow, making them easier to salvage and reducing cleaning costs.

[0021] Furthermore, the two rows of ecological floating islands are arranged in an alternating pattern, with the two rows of ecological floating islands being staggered to allow the central flow channel to form an S-shaped flow channel.

[0022] The further beneficial effects of adopting the above-mentioned staggered arrangement are as follows: it creates more turbulent zones, promotes oxygen exchange, thereby increasing DO concentration, enhancing the activity of aerobic microorganisms, promoting microbial degradation, and improving purification efficiency.

[0023] Furthermore, the distance between two adjacent ecological floating islands in each row is 1 to 2 times the length of the bottom edge of the floating bed, and the tip of the ecological floating island is not close to the center of the three-sided smooth river channel.

[0024] The further beneficial effects of adopting the above are as follows: the distance between two adjacent ecological floating islands in each row is 1 to 2 times the length of the bottom edge of the floating bed, avoiding blockage caused by the dense density of ecological floating islands; the tip of the ecological floating island is not close to the center of the three-sided smooth river channel, avoiding the risk of scouring caused by excessively fast flow velocity in the central channel.

[0029] 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.

[0030] Example 1

[0031] like Figure 1 , Figure 2 As shown, a magnetically attracted ecological floating island system for use in a three-sided smooth river channel under slow-flow conditions includes: an ecological floating island 1, which is arranged within a three-sided smooth river channel 2. Each ecological floating island 1 is attracted to a magnetic steel bar 211 within one of the two concrete riverbanks 210 of the three-sided smooth river channel 2 via a magnet 3. In implementation, the location of the magnetic steel bar 211 is first found within the concrete riverbank 210 of the three-sided smooth river channel 2, and then the ecological floating island 1 is attracted to the magnetic steel bar 211 within the concrete riverbank 210 via the magnet 3. The ecological floating island 1 is fixed to the concrete riverbank 210 of the three-sided smooth river channel 2 using a magnetic attraction method. This allows the ecological floating island 1 to be fixed without damaging the concrete structure, thus protecting the integrity of the concrete riverbank 210. This avoids the drilling construction required by traditional anchoring methods and solves the problem of difficult installation of traditional ecological floating islands in the three-sided smooth river channel 2 under slow flow conditions (0.1m / s-0.3m / s). It also reduces manual labor. The magnetic attraction fixing scheme allows for timely addition or removal of the ecological floating island 1 during dry and flood seasons, preventing flood discharge problems caused by an excessive number of ecological floating islands 1 during the flood season, thus providing flexibility.

[0032] Example 2

[0033] like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on embodiment 1, as detailed below:

[0034] The floating bed 110 in the ecological floating island 1 is triangular in shape. A magnet 3 is provided on the bottom edge of the floating bed 110 to attract the magnetic steel bar 211. The floating bed 110 is designed as a triangle so that the floating bed 110 forms a certain angle with the direction of water flow, thereby reducing the impact of water flow on the ecological floating island 1 and preventing the ecological floating island 1 from falling off.

[0035] Example 3

[0036] like Figure 1 As shown, this embodiment is a further improvement on embodiment 2, as detailed below:

[0037] Each ecological floating island 1 has a rounded corner 111 at the apex between the two sides of the floating bed 110. The rounded corner design of the tip of the triangular floating bed 110 reduces the damage to the structure caused by water flow impact and extends its service life.

[0038] Example 4

[0039] like Figure 1 As shown, this embodiment is a further improvement on embodiment 2 or 3, as detailed below:

[0040] The inclination angles of both sides of the floating bed 110 are 30° to 60°, and this angle range can disperse the impact of water flow on the floating bed 110.

[0041] Example 5

[0042] like Figure 2 As shown, this embodiment is a further improvement on any one of embodiments 1 to 4, as detailed below:

[0043] Plants 120 are planted on the floating bed 110 in the ecological floating island 1, and artificial aquatic plants 130 are suspended below the floating bed 110 in the ecological floating island 1. While removing algae, they enrich microorganisms, break the monotony of hard waterways, and enhance aesthetics. In this embodiment, the artificial aquatic plants 130 are preferably modified artificial aquatic plants.

[0044] Example 6

[0045] like Figure 2 As shown, this embodiment is a further improvement on embodiment 5, as detailed below:

[0046] In the ecological floating island 1, a guide plate 140 is provided below the floating bed 110. The guide plate 140 below the floating bed 110 can increase the disturbance of the water flow.

[0047] Example 7

[0048] like Figure 1 , Figure 2 As shown, this embodiment is a further improvement on any one of embodiments 1 to 6, as detailed below:

[0049] There are multiple ecological floating islands 1, arranged in two rows in a sawtooth pattern along the direction of water flow. There is a central channel between the two rows of ecological floating islands 1 to allow water to pass through. One row of ecological floating islands 1 is attracted to the magnetic steel bar 211 in one of the two concrete riverbanks 210 of the three-sided smooth river channel 2 by magnet 3, and the other row of ecological floating islands 1 is attracted to the magnetic steel bar 211 in the other concrete riverbank 210 by magnet 3. This form can create a slow flow zone and a turbulent flow zone, increasing the diffusion of oxygen and microorganisms in the water. In addition, floating objects are collected in the concave area between the two ecological floating islands 1 due to the action of water flow, which is convenient for retrieval and reduces cleaning costs.

[0050] Example 8

[0051] like Figure 1 As shown, this embodiment is a further improvement on embodiment 7, as detailed below:

[0052] The two rows of ecological floating islands 1 are arranged in an alternating pattern. The staggered arrangement of the two rows of ecological floating islands 1 allows the central flow channel to form an S-shaped flow channel. The alternating arrangement creates more turbulent areas, promotes oxygen exchange, thereby increasing the DO concentration, enhancing the activity of aerobic microorganisms, promoting microbial degradation, and improving purification efficiency.

[0053] Example 9

[0054] like Figure 1 As shown, this embodiment is a further improvement on embodiment 7 or 8, as detailed below:

[0055] The spacing of the ecological floating islands 1 should ensure coverage area without affecting the river. Therefore, the spacing between two adjacent ecological floating islands 1 in each row should be 1 to 2 times the bottom side length of the floating bed 110 to avoid blockage caused by the dense arrangement of the ecological floating islands 1. The tips of the ecological floating islands 1 set at both ends should not be close to the center of the three-sided smooth river channel 2 to avoid the risk of scouring due to excessive flow velocity in the central channel. Assuming the river channel is 300m long and 30m wide, the distance between the tips of the ecological floating islands 1 on both sides should be greater than 9m.

[0056] 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.
