Technical Field

[0001] The present invention relates to the field of ecological floating islands. Background Art

[0002] With the enrichment of water environment purification technologies, the technology of degrading the contents of COD, nitrogen, and phosphorus in water bodies by ecological floating islands through eutrophic water quality and ecological engineering principles has been widely applied. The main function of ecological floating island water purification is to utilize the roots of plants to absorb eutrophic substances in the water body, such as total phosphorus, ammonia nitrogen, organic matter, etc., so as to transfer the water body nutrients and reduce the peculiar smell and eutrophication caused by water body enclosure or insufficient self-circulation. It can greatly improve the transparency of the water body and effectively improve the water quality indicators.

[0003] However, in actual environmental governance projects, the wide application of ecological floating islands has also encountered many problems, especially the problem of fish in the water body gnawing on the roots of aquatic plants on the ecological floating islands, and the problem that the residues of plant metabolism falling into the water form new pollution to the water body. Among the patented technologies announced by the State Intellectual Property Office, there are technologies for preventing fish from gnawing on the roots of aquatic plants on ecological floating islands. In actual applications, there are also practical cases of using isolation nets to prevent fish from gnawing on the roots. However, none of the solutions can solve the problem of the residues such as the rotting of the roots of aquatic plants on the ecological floating islands, the peeling of the epidermis, and the organic matter particles formed by the death of algae and microorganisms re-polluting the water body. Summary of the Invention

[0011] In the improved solution, the upper end of the sloping bottom plate is connected to the fish-proof net, and it is used to collect and gather the metabolic residues generated by the ecological floating island.

[0012] In the improved solution, the horizontal dimension of the sloping bottom plate gradually shrinks from the opening towards the slag outlet.

[0024] The present invention will be described in detail below with reference to the accompanying drawings.

[0025] This embodiment discloses a floating island system. As Figure 2 shown, it includes a floating island for planting aquatic plants and a floating island slag collection and drainage unit. The floating island is used for planting aquatic plants. The floating island slag collection and drainage unit is located in the water body below the floating island and can be used to collect and discharge the root residues of the aquatic plants on the floating island.

[0026] As Figure 1 shown, the floating island slag collection and drainage unit includes:

[0027] A slag collection unit, which is located below the floating island and connected to the floating island. It has a slag collection cavity inside. The slag collection unit has an opening and a slag collection port with a size smaller than the opening. The residues of the plant roots enter the slag collection cavity through the opening and fall to the slag collection port. The slag collection unit at least includes a section of mesh structure, and the mesh structure can restrict fish from entering the slag collection cavity and can enable the water body in the slag collection cavity to exchange with the outside.

[0028] A slag drainage unit, one end of which is connected to the slag collection port of the slag collection unit and can discharge the residues collected at the slag collection port from the water body;

[0029] A connection unit, which can connect the slag collection unit to the floating island.

[0030] In a preferred embodiment, the connection unit is a hanging ring 1, which is used to connect the floating island slag collection and drainage unit to the ecological floating island. The hanging ring 1 is preferably a metal anti-rust circular ring and is connected to two or more hooks on the ecological floating island. Using a metal anti-rust circular hanging ring has the beneficial effect of being convenient for disassembly and can hang large and heavy metabolic residues. In some other embodiments, the connection unit can also be bolts, metal wires, etc. Or in some embodiments, the mesh structure is directly connected to the floating island. Specifically, hooks are provided on the floating island, and the mesh structure is directly connected to the hooks.

[0031] In a preferred embodiment, the mesh structure is a fish-proof net 2. Preferably, the mesh diameter of the fish-proof net 2 is 2 cm, and it is used to prevent fish from entering the slag collection cavity under the ecological floating island from the side to gnaw on the roots of aquatic plants. One end of the fish-proof net 2 is connected to the hanging ring 1. More specifically, the fish-proof net 2 is an annular structure matching the horizontal cross-sectional size of the floating island. The floating island is usually a square structure, and the fish-proof net 2 is a square annular structure.

[0032] In a preferred embodiment, the lower end of the mesh structure is a sloped bottom plate 3. Preferably, the material of the sloped bottom plate 3 is a smooth plastic material, a metal material, etc. In a preferred solution, it is funnel-shaped, and the lower slope angle is about 40 degrees. It is used to collect a large amount of metabolic residues of aquatic plants. The metabolic residues of aquatic plants sink and fall onto the sloped bottom plate and will not float out of the sloped bottom plate 3 with the water waves. The inner inclined surface structure of the sloped bottom plate 3 is smooth to prevent plant residues from accumulating on it. Multiple holes can be provided in the upper part of the sloped bottom plate. The anti-fish net 2 has multiple lines passing through the hole structure and the sloped bottom plate, and the space between the anti-fish net 2 and the sloped bottom plate can prevent fish from passing through. In some other embodiments, the size of the sloped bottom plate 3 can also be a triangular structure.

[0033] The size of the opening matches the size of the floating island to be able to collect the residues of aquatic plants on the floating island.

[0034] The slag collection port 4, preferably, is made of hard plastic material and has a circular cross-section. It is the conveying port for the metabolic residues of aquatic plants collected by the sloped bottom plate 3. In some embodiments, the slag collection port 4 is at the exact center of the entire sloped bottom plate 3.

[0035] In a preferred embodiment, the slag discharge unit includes

[0036] A slag collection pipe 5, which is connected to the slag collection port and is used to convey the metabolic residues in the slag collection port 4;

[0037] An auxiliary floating block 6, which is connected to the slag collection pipe and is used to float the end of the slag collection pipe 5 on the water surface;

[0038] A slag collection pipe interface 7, which is used to connect to an external sewage pump assembly.

[0039] In a more preferred solution, the slag collection pipe has a smooth inner wall, is easy to bend, and is made of plastic material with an inner diameter of 5 - 10 cm. It is used as the conveying pipe for the metabolic residues of aquatic plants in the floating island slag collection and discharge unit.

[0040] The auxiliary floating block 6 is a foam block and is used to place the end of the above-mentioned slag collection pipe 5 on the water surface. The slag collection pipe interface 7 is used to connect to an external sewage pump assembly and discharge the metabolic residues of aquatic plants collected by the floating island slag collection and discharge unit.

[0041] The floating island integrated slag discharging unit described in this embodiment can start the external sewage pump assembly regularly or irregularly during use, so as to discharge the residues collected at the slag collecting port 4 in time. When the floating island integrated slag discharging unit is put into operation, fish with slightly larger sizes cannot enter the slag collecting cavity, thus preventing fish from gnawing on the aquatic plant roots of the ecological floating island to the greatest extent. When the metabolic residues generated by the ecological floating island system fall, they sink and land on the funnel-shaped bottom of the device. Under the action of water fluctuations, most of them concentrate towards the slag collecting port along the funnel-shaped slope and can be discharged in time through the external sewage pump.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
