DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present utility model will be further described below with reference to the drawings and embodiments.

[0018] The urban lake water ecological restoration floating bed of the present utility model, such as Figure 1 , Figure 2 and Figure 3As shown in the figure, it includes a frame 1. The frame 1 is fixedly connected with a floating body 2. The floating body 2 can float on the lake surface and can bear a large buoyancy, so that the frame 1 and other components can also float on the lake surface. A support frame 3 is arranged inside the frame 1. The support frame 3 is fixedly connected with the frame 1. Multiple planting grooves are arranged on the support frame 3. Each planting groove is provided with a planting pot 4. The planting pot 4 can be made of a plastic pot, which is light in weight. A plurality of water holes are arranged at the bottom and lower part of the planting pot 4, so that lake water can enter and exit the planting pot 4. An adsorption filler layer 5 is arranged at the bottom of the inner cavity of the planting pot 4. A plant 6 is arranged above the adsorption filler layer 5. The plant 6 can be various existing aquatic organisms, such as Iris pseudacorus, etc. The adsorption filler layer 5 is a granular material, and the roots of the plant 6 can extend into the gaps of the adsorption filler layer 5 to facilitate the absorption of nutrients. When cultivating the plant 6, a nutrient substrate can be arranged on the surface of the adsorption filler layer 5. As the plant 6 grows, its roots can enter the adsorption filler layer 5. Since solid impurities in lake water, such as sludge, aquatic organism feces, etc., usually carry a large amount of nutrients, the adsorption filler layer 5 is used to adsorb and intercept the solid impurities in the lake water, so that the solid impurities stay in the planting pot 4, which is beneficial to the rapid absorption of nutrients by the roots of the plant 6 and improves the purification effect on the lake water.

[0019] The plant 6 can absorb the nutrients in the surface layer of the lake water. Since the water body of the urban inner lake has poor fluidity, the nutrients in the middle and lower layers of the lake water are not easily absorbed by the plant 6. Therefore, in the present utility model, a plurality of horizontal suspension beams 7 are arranged at the bottom of the support frame 3. Each suspension beam 7 is provided with a braided belt type filler 8 in a suspended manner. The braided belt type filler 8 is a flexible filler, which can provide a growth place for microorganisms. Aerobic microorganisms, anaerobic microorganisms, etc. can attach to the surface of the braided belt type filler 8 and grow. During the growth process of the microorganisms, the nitrogen in the lake water can be decomposed. The braided belt type filler 8 can extend into the middle and lower layers of the lake water, so the middle and lower layers of the lake water can be purified.

[0020] In the present utility model, the nutrients in the lake water are absorbed simultaneously by the plant 6 and the microorganisms attached to the surface of the braided belt type filler 8, which can improve the removal effect of the nutrients in the lake water.

[0021] In order to increase the oxygen content in the lake water, prevent the growth of anaerobic microorganisms due to oxygen deficiency in the water body, and ensure the normal survival of fish in the lake, an aerator 9 is provided at the center of the support frame 3. The aerator 9 is connected to a vertical air supply pipe 10. The air supply pipe 10 is a telescopic pipe, and the lower end of the air supply pipe 10 extends below the braided belt packing 8. The aerator 9 can adopt air supply equipment such as an air pump, which can transport air into the air supply pipe 10, and the air supply pipe 10 then transports the air to the lower layer of the lake water. After the air enters the lake water, part of the oxygen dissolves in the lake water, increasing the oxygen content of the lake water. At the same time, air forms bubbles in the lake water, and the bubbles move upward to the lake surface, disturbing the water body, promoting the flow of the lake water, and improving the fluidity of the water body. In addition, when the bubbles move, they drive the nutrient components in the lower layer of the lake water to flow upward to the braided belt packing 8 and the planting pot 4, which is beneficial for the plants 6 and the microorganisms attached to the surface of the braided belt packing 8 to absorb pollution components such as nitrogen and phosphorus in the lake water. Since the depths of the lake water at different positions are different, in order to make the length of the air supply pipe 10 suitable for lake water of different depths, the air supply pipe 10 adopts a telescopic pipe, that is, a pipe that can be extended and shortened, and its length can be adjusted. Specifically, the telescopic pipe can include a fixed pipe and a lifting pipe. The inner thread is provided inside the fixed pipe, and the outer thread is provided on the outer wall of the lifting pipe. The upper end of the lifting pipe extends into the lower end of the fixed pipe, and the lifting pipe is in threaded cooperation with the fixed pipe. The fixed pipe is detachably connected to the aerator 9.

[0022] In the present utility model, the adsorption packing layer 5 can be pebbles. As a more preferred embodiment, the adsorption packing layer 5 is a ceramsite layer with a rough surface. The density of the ceramsite is smaller, which is beneficial to reducing the weight of the entire planting pot 4. The rough surface of the ceramsite is beneficial to adsorbing solid impurities in the lake water.

[0023] In order to keep the position of the entire floating bed stable, the frame 1 is connected with a plurality of flexible positioning ropes 11. The positioning ropes 11 can be four, which are respectively located around the floating bed. Fixed anchor nails can be set at the bottom of the lake or on the shore, and the positioning ropes 11 are tied to the fixed anchor nails, so that the floating bed can be kept stable.

[0024] In the present utility model, the frame 1 can be circular. As a preferred embodiment, the frame 1 includes four rectangular steels. The two ends of the rectangular steels are sealed by end plates 12. The end plates 12 can be welded to the rectangular steels. Adjacent two rectangular steels are welded to form a rectangular frame 1. The rectangular steels have high strength, can stably support the support frame 3, and there is a cavity inside the rectangular steels. After the two ends of the rectangular steels are sealed by the end plates 12, the overall density of the rectangular steels is smaller, which is beneficial to floating on the lake surface.

[0025] In the present utility model, the floating body 2 adopts a rectangular ring-shaped airbag. The airbag can be arranged on the outer side wall or the lower surface of the frame 1, and the airbag is tied and fixed to the frame 1 by a plurality of ropes.

[0026] In the present utility model, the support frame 3 includes a horizontal support plate 33 and a plurality of mutually parallel cross beams 31. The cross beams 31 can be made of profiles such as angle steel and channel steel. The two ends of the cross beams 31 are fixedly connected to the frame 1, specifically, they can be welded to the inner side wall of the frame 1. The cross beams 31 are perpendicular to the suspension beam 7. The suspension beam 7 can be made of a steel plate with a thickness of about 2 mm and a width of about 20 mm. The cross beams 31, the support plate 33, and the suspension beam 7 are arranged in sequence from top to bottom, and the cross beams 31, the support plate 33, and the suspension beam 7 are fixedly connected. Specifically, the cross beams 31, the support plate 33, and the suspension beam 7 can be connected by bolts. The planting groove is a through hole provided on the support plate 33. The through hole can be a circular hole. The planting pot 4 can be a pot body with a frustum or cylindrical shape. The shape of the through hole is adapted to the shape of the planting pot 4. An annular clamping plate 41 is provided on the outer wall of the planting pot 4. The planting pot 4 is located within the through hole, and the clamping plate 41 is supported by the upper surface of the support plate 33. When installing the planting pot 4, the planting pot 4 can be placed into the through hole. When it is necessary to disassemble the planting pot 4, the planting pot 4 can be directly taken out. Both installation and disassembly are very convenient.

[0027] When implementing the present utility model, a plurality of floating beds can be evenly arranged on the lake surface according to the size of the lake surface. Or at intervals of a certain period of time, the floating beds can be pulled to move to other areas of the lake surface.

[0028] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
