Description

Technical Field

[0001] This utility model relates to the field of constructed wetland technology, and in particular to a floating constructed wetland. Background Technology

[0002] Constructed wetlands are artificial wastewater treatment technologies that simulate natural wetland ecosystems. They purify wastewater through the synergistic effects of plants, substrate materials, and microorganisms, and are typically floating on rivers or lakes.

[0003] Currently, existing floating constructed wetlands are subject to direct impact from the rapid and large-volume flow of heavy rain during use. Constructed wetlands lack strong degradation and treatment capabilities when dealing with rainwater runoff, which can easily damage them. Therefore, in order to improve the effectiveness of constructed wetlands and to promote technological advancement and enhance core technological competitiveness in the industry, this application proposes a new implementation scheme that differs from existing floating constructed wetlands and application methods. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing constructed wetlands lack strong degradation and treatment capabilities when dealing with storm runoff, which easily damages the constructed wetlands. Therefore, a floating constructed wetland is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A floating artificial wetland includes a floating platform and a water-blocking cover. Multiple first connecting lugs are fixedly connected to both sides of the floating platform, and multiple planting baskets are snapped onto the top of the floating platform. Multiple second connecting lugs are fixedly connected to the outer wall of one side of the water-blocking cover. Fastening bolts are threadedly connected between two adjacent first connecting lugs and between the second connecting lug and the first connecting lug of one of the floating platforms. Multiple water outlet pipes are sealed and inserted into one side of the water-blocking cover. Drainage pipes are inserted into both ends of the water outlet pipes, and clamps are fitted at the connection between the drainage pipes and the water outlet pipes.

[0007] Furthermore, the planting basket is provided with multiple perforations.

[0008] Furthermore, the planting basket is lined with a layer of expanded clay filler, and a layer of silt filler is laid on top of the expanded clay filler.

[0009] Furthermore, a filter screen with an L-shaped structure is rotatably connected between the inner walls of the two sides of the water shield via a rotating shaft.

[0010] Furthermore, a baffle is fixedly connected to the top of the floating platform, and the baffle has an arc-shaped structure.

[0011] Furthermore, the drain pipe is placed between the two baffles.

[0012] Furthermore, connecting ropes are attached to the first connecting lugs at both ends of the floating platform.

[0013] Furthermore, the drain pipe is a PVC flexible hose.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Rainwater runoff is discharged through outlet and drainage pipes over the floating constructed wetland, thus avoiding damage to the floating constructed wetland.

[0016] 2. Multiple floating platforms can be assembled together to meet different needs by aligning the first connecting lug mounting holes of one floating platform with the first connecting lug mounting holes of another floating platform, inserting fastening bolts into the aligned mounting holes and tightening them.

[0017] 3. By fixing one end of the connecting rope to a fixed object, the floating artificial wetland is fixed in a set position, thereby preventing the floating artificial wetland from drifting with the water flow. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-4A floating artificial wetland includes a floating platform 1 and a water-blocking cover 7. Both sides of the floating platform 1 are integrally formed with multiple first connecting ears 2. Multiple planting baskets 3 are snapped onto the top of the floating platform 1. The floating platform 1 serves as the basic support frame of the system and provides an installation platform for the planting baskets 3.

[0025] The outer wall of one side of the water shield 7 is integrally formed with multiple second connecting ears 8. Fastening bolts 9 are threadedly connected between two adjacent first connecting ears 2 and between the second connecting ear 8 and the first connecting ear 2 of one of the floating platforms 1. Align the mounting holes of the first connecting ears 2 of one floating platform 1 with the mounting holes of the first connecting ears 2 of another floating platform 1, and then insert the fastening bolts 9 into the aligned mounting holes and tighten them, thereby assembling multiple floating platforms 1 together.

[0026] Multiple water outlet pipes 10 are sealed and inserted on one side of the water shield 7. Drainage pipes 11 are inserted at both ends of the water outlet pipes 10. Rainwater runoff passes over the floating constructed wetland and is discharged from the water outlet pipes 10 and the drainage pipes 11, thereby avoiding damage to the floating constructed wetland.

[0027] A clamp 12 is fitted at the connection between the drain pipe 11 and the outlet pipe 10 to fix the connection between the drain pipe 11 and the outlet pipe 10.

[0028] The planting basket 3 has multiple perforations 4 so that aquatic plants can absorb water through the perforations 4;

[0029] The planting basket 3 is filled with a layer of expanded clay filler 5, and a layer of silt filler 6 is laid on top of the expanded clay filler 5. The expanded clay filler 5 inside provides a good drainage and aeration environment, while the silt filler 6 provides nutrients and a growth medium for the plants.

[0030] A filter screen 13 is rotatably connected between the inner walls of both sides of the water baffle 7 via a rotating shaft. The filter screen 13 has an L-shaped structure, and impurities are intercepted and filtered by the filter screen 13 to prevent blockage of the water outlet pipe 10 and the drain pipe 11.

[0031] The top of the floating platform 1 is integrally formed with a baffle 14, which has an arc-shaped structure. The drain pipe 11 is placed between the two baffles 14. A connecting rope 15 is attached to the first connecting lug 2 at both ends of the floating platform 1. One end of the connecting rope 15 is fixed to a fixed object, thereby fixing the floating artificial wetland in a set position and preventing the floating artificial wetland from drifting with the water flow.

[0032] Drain pipe 11 is a PVC flexible hose. The PVC flexible hose material of drain pipe 11 has good flexibility and durability, ensuring stable drainage during long-term use.

[0033] The working principle of this embodiment is as follows: In use, firstly, multiple floating platforms 1 are assembled together. Then, the mounting holes of the second connecting ears 8 of the water-blocking cover 7 are aligned with the mounting holes of the first connecting ears 2 of one of the floating platforms 1, and then the water-blocking cover 7 is installed on one side of the multiple floating platforms 1 using fastening bolts 9. Then, the floating artificial wetland is placed in the water, and one end of the connecting rope 15 is fixed on both banks of the river to fix the floating artificial wetland, so that the water flow direction is perpendicular to the floating platform 1 and the water-blocking cover 7, thereby preventing the floating artificial wetland from drifting with the water flow. Then, the drain pipe 11 is connected to the outlet pipe 10 through two connecting ropes 15, and the clamp 12 is locked and fixed. Then, the drain pipe 11 is placed between two baffles 14 to complete the assembly of the floating artificial wetland.

[0034] Then, the planting basket 3 is placed on the floating platform 1, and a layer of expanded clay filler 5 and a layer of silt filler 6 are laid in the planting basket 3. Then, holes are dug and aquatic plants are planted. The aquatic plants then absorb water through the perforations 4 to facilitate their growth.

[0035] During heavy rain, the rainwater shield 7 is used to block the rainwater runoff. Then, when the rainwater runoff passes over the floating artificial wetland, it is discharged from the outlet pipe 10 and the drain pipe 11, thereby avoiding impact damage to the floating artificial wetland. The impurities are intercepted and filtered by the filter screen 13 to prevent blockage of the outlet pipe 10 and the drain pipe 11, and at the same time, it is convenient for later cleaning.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
