This prior art sets a culture space at the root system of the plants planted in the ecological suspended bed, and inputs a functional microbial community into the culture space, thereby increasing the content of functional microorganisms in the culture space, keeping the plant roots in a highly active state, and thus achieving a purification effect on the water body through the ecological suspended bed.

[0004] In order to effectively prolong the retention time of the functional microbial community in the culture space, a mesh plate is also provided in the culture space in the above-mentioned prior art, and the mesh plate is used to reduce the water flow between the inside and outside of the culture space, so that the plant roots can grow rapidly under the action of the functional microbial community. However, the mesh plate's blocking of the external water body will also cause the plant roots to be unable to fully exert their water purification effect, ultimately reducing the restoration efficiency of the river ecological restoration project.

DETAILED DESCRIPTION

[0020] The following will be combined Figure 1-Figure 2 The present invention is further illustrated by the following embodiments.

[0021] This embodiment discloses a suspended bed device with water body ecological restoration function.

[0022] Reference Figure 1 The suspended bed device with water body ecological restoration function includes a planting platform 11, and a floating plate 2 is arranged around the planting platform 11. The planting platform 11 is arranged on the water surface of the river through the floating plate 2. A planting trough is provided on the top of the planting platform 11, and the planting trough is filled with soil 12. The soil 12 in the planting trough is used for planting plants. A first through hole 13 is provided at the bottom of the planting platform 11, and the first through hole 13 penetrates upward into the planting trough, and the first through hole 13 is provided for the plant roots to pass through. A base frame 3 is provided at the bottom of the planting platform 11, and a mesh plate 41 is provided on the base frame 3. The mesh plate 41 is provided with a second through hole 42, and a culture space for the growth of plant roots is formed between the planting platform 11, the base frame 3 and the mesh plate 41. A pipeline is connected to one side of the base frame 3, and the pipeline is externally connected to a microbial breeding device. The pipeline is used to add functional microbial communities into the culture space to ensure the rapid growth of plant roots.

[0023] Reference Figure 1 , the mesh plate 41 is vertically movably arranged on the base frame 3, and the mesh plate 41 and the base frame 3 are elastically connected in the vertical direction. Furthermore, a plurality of conical columns 5 are arranged at the bottom of the planting platform 11, and the conical columns 5 are large at the top and small at the bottom, and the plurality of conical columns 5 pass through the plurality of second through holes 42 in a one-to-one correspondence. Through the above arrangement, after the plants are planted in the planting trough, the functional microbial community is added into the culture space through the pipeline. At this time, due to the arrangement of the mesh plate 41 and the conical columns 5, the fluidity of the water inside and outside the culture space is poor, so that the retention time of the functional microbial community in the culture space can be effectively extended, ensuring that the plant root system can grow rapidly under the action of the functional microbial community. Afterwards, as the plant roots gradually grow, the mesh plate 41 will be pushed down by the plant roots. On the one hand, this will enlarge the culture space to meet the growth needs of the plant roots. On the other hand, the second through holes 42 of the mesh plate 41 will gradually enlarge. When the plant roots mature, the water fluidity inside and outside the culture space will be improved, and the water purification effect of the plant roots will be fully exerted, ultimately improving the restoration efficiency of the river ecological restoration project.

[0024] Reference Figure 1 and Figure 2 A U-shaped rod 6 is connected between the mesh plate 41 and the base frame 3, and a telescopic hole is opened at the bottom of the base frame 3. One end of the U-shaped rod 6 is connected to the bottom of the mesh plate 41 and the other end is inserted into the telescopic hole of the base frame 3. A first spring 71 is connected between the end of the U-shaped rod 6 and the inner end of the telescopic hole. The mesh plate 41 and the base frame 3 are elastically connected through the U-shaped rod 6 and the first spring 71. When the mesh plate 41 is pushed down by the plant roots, the first spring 71 is gradually stretched. Furthermore, a one-way limit assembly is provided between the side wall of the mesh plate 41 and the side wall of the base frame 3, and the one-way limit assembly includes a first wedge block 81 and a second spring 72 provided on the side wall of the mesh plate 41, and includes a plurality of second wedge blocks 82 provided on the side wall of the base frame 3, wherein the first wedge block 81 is laterally connected to the side wall of the mesh plate 41 by the second spring 72 to achieve lateral extension and contraction, and the inclined surface of the first wedge block 81 faces downward, and the plurality of second wedge blocks 82 are arranged in a vertical direction on the side wall of the base frame 3, and the inclined surfaces of the second wedge blocks 82 face upward. When the first wedge block 81 moves downward with the mesh plate 41 and contacts the second wedge block 82, the first wedge block 81 will be subjected to the pressure of the second wedge block 82 and force the second spring 72 to compress, that is, the first wedge block 81 will retract, and when the first wedge block 81 passes the second wedge block 82, the first wedge block 81 will extend again due to the shape recovery of the second spring 72. At this time, the second wedge block 82 above will limit the first wedge block 81 to prevent the first wedge block 81 from moving upward, and finally achieve unidirectional limitation of the mesh plate 41, which can prevent the plant roots from being continuously subjected to upward pressure after pushing the mesh plate 41 downward, thereby protecting the plant roots.

[0025] Reference Figure 1 The conical column 5 is a hollow column with release holes inside and outside. The conical column 5 is filled with nutrients needed by the plant roots during growth. In this embodiment, the conical column 5 is filled with natural materials rich in organic matter and trace elements such as coconut shell fiber or straw, which provide nutrients required for plant growth while avoiding river pollution. At this time, the plant roots will tend to grow on the conical column 5, so that the conical column 5 can provide a foundation for the plant roots to attach and improve the strength of the plant roots. Furthermore, a threaded rod is provided at the top of the conical column 5, and a threaded hole is provided at the bottom of the planting platform 11. The conical column 5 is threadedly connected to the threaded hole of the planting platform 11 through the threaded rod, which is convenient for disassembling and assembling the conical column 5 to supplement or replace the material inside the conical column 5 during the next breeding process.

[0026] Reference Figure 1 A fixing frame is provided at the bottom of the floating plate 2, and the fixing frame includes a plurality of telescopic rods 9. The upper ends of the telescopic rods 9 are connected to the bottom of the floating plate 2 and the lower ends are provided with hooks. The telescopic rods 9 grasp the riverbed of the river channel through the hooks at their lower ends, thereby positioning the planting platform 11.

[0027] The above are all preferred embodiments of the present invention, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
