Technical Field
[0001] This utility model relates to the field of ecological floating bed technology, and in particular to a floating bed-type ecological purification device for eutrophic water bodies. Background Technology
[0002] The discharge of large amounts of industrial wastewater, agricultural runoff, and domestic sewage containing nutrients such as nitrogen and phosphorus into rivers, lakes, and reservoirs has led to increasingly severe eutrophication problems. In eutrophic waters, algae (such as cyanobacteria and green algae) proliferate abnormally, forming algal blooms that consume large amounts of dissolved oxygen, causing water quality deterioration, decreased water transparency, and potentially releasing algal toxins. This severely disrupts the balance of aquatic ecosystems and threatens drinking water safety. Biological ecological methods are currently a research and application hotspot, primarily utilizing the metabolic processes of plants, microorganisms, or aquatic animals to absorb, degrade, and transform pollutants in water. Traditional ecological floating bed technology typically involves planting terrestrial or aquatic plants on a floating carrier, utilizing the plant roots to absorb nutrients such as nitrogen and phosphorus from the water, thereby purifying the water. However, existing technologies have the following problems: The floating islands used in existing ecological floating bed technology are usually fixed to each other with bolts. If the area of the floating islands required on the water surface is large, the installation efficiency will be reduced by installing each bolt individually. At the same time, traditional floating beds mainly rely on the absorption of plant roots, and the purification efficiency is greatly affected by the plant growth cycle and seasonal changes. Especially in the early stage of plant growth or in winter, the purification effect will be significantly reduced. For complex pollutants in water, such as organic pollutants and suspended particles, the removal capacity is limited. Utility Model Content
[0003] The main purpose of this utility model is to provide a floating bed-type ecological purification device for eutrophic water bodies, which can effectively solve the problems of complicated connection between floating island modules, low installation efficiency, single purification method, unstable effect and insufficient ability to remove complex pollutants.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A floating bed-type ecological purification device for eutrophic water bodies includes a floating island mechanism. The floating island mechanism includes a hollow floating island plate. A docking plate is fixedly installed on the front and right sides of the hollow floating island plate. The docking plate has a through-hole. A docking plate is fixedly installed on the rear and left sides of the hollow floating island plate. A docking hole is opened on the side of the docking plate away from the hollow floating island plate. The docking hole has the same size as the docking plate. The hollow floating island plate has a through-hole. A plant basket is fixedly installed in the inner circle of the through-hole. A purification mechanism is arranged below the plant basket.
[0005] Preferably, a card plate control box is fixedly installed on the top of each of the two docking plates, a spring is fixedly installed on the top of the inner wall of each of the two card plate control boxes, and an inclined card plate is fixedly installed on the bottom of the spring, with the bottom end of the inclined card plate penetrating into the inner cavity of the docking hole.
[0006] Preferably, the side of the inclined plate away from the hollow plate of the floating island is an inclined surface, and the side of the inclined plate close to the hollow plate of the floating island is a vertical surface, and the width of the inclined plate is consistent with the plate hole.
[0007] Preferably, a lifting rod located inside the spring is fixedly installed at the top of the inclined plate, and the top of the lifting rod extends through to the top of the plate control box.
[0008] Preferably, the plant basket has several plant root holes that penetrate its inner cavity on both its side and bottom. A mounting block is fixedly installed on the bottom of the plant basket.

[0011] 2. This utility model provides a floating bed-type ecological purification device for eutrophic water bodies. By combining a plant basket with a purification mechanism suspended below it, the plant roots can absorb nutrients such as nitrogen and phosphorus in the water.

Detailed Implementation
[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0015] like Figure 1 , Figure 2 As shown, a floating bed type ecological purification device for eutrophic water bodies includes a floating island mechanism 1. The floating island mechanism 1 includes a hollow floating island plate 11. A docking plate 12 is fixedly installed on the front and right sides of the hollow floating island plate 11. The docking plate 12 has a through-hole 13. A docking plate 14 is fixedly installed on the rear and left sides of the hollow floating island plate 11. A docking hole 15 is opened on the side of the docking plate 14 away from the hollow floating island plate 11. The docking hole 15 has the same size as the docking plate 12. The hollow floating island plate 11 has a through-hole 111. A plant basket 2 is fixedly installed in the inner circle of the through-hole 111. Below the plant basket 2... A purification mechanism 3 is provided. A card control box 16 is fixedly installed on the top of each of the two docking plates 14. A spring 17 is fixedly installed on the top of the inner wall of each of the two card control boxes 16. An inclined card 18 is fixedly installed on the bottom of the spring 17. The bottom end of the inclined card 18 extends through the inner cavity of the docking hole 15. The side of the inclined card 18 away from the floating island hollow plate 11 is inclined, and the side of the inclined card 18 close to the floating island hollow plate 11 is vertical. The width of the inclined card 18 is the same as that of the card hole 13. A lifting rod 19 located inside the spring 17 is fixedly installed on the top of the inclined card 18. The top end of the lifting rod 19 extends through the top of the card control box 16. When laying large-area floating islands, the operator can align the docking plate 12 on one hollow floating island plate 11 with the docking hole 15 on the adjacent hollow floating island plate 11, and then push it in horizontally. During the pushing process, the end of the docking plate 12 will contact and press the inclined surface of the inclined plate 18. Under the action of the pressing force, the inclined plate 18 overcomes the elastic force of the spring 17 and moves upward, thus making room. When the docking plate 12 is fully inserted and its plate hole 13 moves to directly below the inclined plate 18, the inclined plate 18 will quickly pop down under the reset action of the spring 17, and its vertical surface will be locked into the plate hole 13, thus firmly locking the two hollow floating island plates 11 together, realizing the rapid splicing between modules and greatly improving the installation efficiency. When disassembly is required, simply lift the lifting rod 19 upward to drive the inclined plate 18 out of the plate hole 13, and the two hollow floating island plates 11 can be separated.
[0016] like Figure 3 , Figure 4 As shown, the plant basket 2 has several plant root holes 21 that penetrate its inner cavity on both its side and bottom. A mounting block 22 is fixedly installed on the bottom of the plant basket 2. A threaded hole 23 is opened on the bottom of the mounting block 22. A threaded block 25 is installed on the inner ring of the threaded hole 23. A hanging rod 24 is fixedly connected to the bottom end of the threaded block 25. After the floating island mechanism 1 is assembled, aquatic plants adapted to the local water body are planted in the plant basket 2. The roots of the plants can grow freely into the water and downwards through the plant root holes 21 on the side wall and bottom of the plant basket 2. The plant roots directly absorb nutrients such as nitrogen and phosphorus in the water and convert them into their own biomass, thereby achieving the first level of direct purification. At the same time, the dense root system also provides a carrier for the attachment of microorganisms. The top of the installation cover 31 is tightened and fixed to the threaded block 25 at the end of the hanging rod 24 and the threaded hole 23 at the bottom of the plant basket 2, so that the entire purification mechanism 3 is stably suspended below the plant basket 2 and submerged in the water.
[0017] like Figure 5 As shown, the purification mechanism 3 includes a mounting top cover 31, the bottom end of the hanging rod 24 is fixedly connected to the top end of the mounting top cover 31, the bottom of the mounting top cover 31 is provided with an annular threaded groove 32, the inner ring of the annular threaded groove 32 is threaded with an external threaded ring 33, the bottom of the external threaded ring 33 is fixedly installed with a stainless steel filter screen cylinder 34, the inner cavity of the stainless steel filter screen cylinder 34 is provided with suspended packing material, which is a porous spherical or cylindrical suspended packing material that sways with the water flow and has a huge specific surface area for the attachment and growth of aerobic microorganisms; The stainless steel filter cylinder 34, loaded with suspended packing material, is screwed into the annular threaded groove 32 at the bottom of the mounting top cover 31 via its external threaded ring 33, thus assembling a complete purification mechanism 3. The suspended packing material inside the stainless steel filter cylinder 34 has a huge specific surface area, which provides an ideal place for the attachment and growth of aerobic microorganisms. As water flows through the stainless steel filter cylinder 34, the suspended packing material inside the cylinder shakes slightly, constantly renewing the contact interface between the biofilm and pollutants, effectively preventing clogging. A large number of microorganisms such as bacteria and fungi attached to the suspended packing material can efficiently degrade and transform dissolved organic matter, ammonia nitrogen and other pollutants in the water.
[0018] The working principle of this floating bed-type ecological purification device for eutrophic water bodies will be explained in detail below.
[0019] like Figure 1-5 As shown, the docking plate 12 and docking hole 15 in the floating island mechanism 1 cooperate to quickly splice and lock multiple hollow floating island plates 11 using the inclined plate 18 and spring 17, forming a large-area floating bed. Subsequently, aquatic plants are planted in the plant basket 2, and their roots extend into the water through the root hole 21 to absorb nutrients such as nitrogen and phosphorus in the water, achieving preliminary purification. At the same time, the stainless steel filter cylinder 34 in the purification mechanism 3, which is suspended below the plant basket 2 by the hanging rod 24, is filled with suspended packing material, which provides an attachment carrier for microorganisms. The microorganisms form a biofilm on the surface of the packing material, further degrading organic matter and pollutants in the water, thereby synergistically improving the purification effect of the water.
