[0037] Reference Figure 1-6 The figure shows a preferred embodiment of the present invention.

[0038] The low-energy ecological floating bed device for improving the water quality of a small-scale receiving water body in a water transfer project provided by the present invention comprises a water collecting tank 100 and a solar energy system for providing electric energy supply. The water collecting tank 100 has a water cavity for accommodating the receiving water body. The water collecting tank 100 is respectively connected to an inlet pipe 120 and an outlet pipe 130. The inlet pipe 120 and the outlet pipe 130 are respectively connected to a river channel for the receiving water body to flow.

[0039] The water cavity is provided with a plurality of grid plates 110 for receiving water to pass through and filter and purify the receiving water. The plurality of grid plates 110 are sequentially arranged at intervals to divide the water cavity into a plurality of water filtering areas which are arranged at intervals and have top openings. Along the flow direction of the receiving water in the water cavity, the plurality of water filtering areas sequentially include a water inlet area, a plurality of intermediate areas and a water outlet area.

[0040] The water inlet pipe 120 is connected to the water inlet area, and the water outlet pipe 130 is connected to the water outlet area. The receiving water in the upper reaches of the river is discharged to the water inlet area through the water inlet pipe 120. The receiving water passes through the water inlet area, multiple intermediate areas and the water outlet area in sequence to form a purified water body. The purified water body is discharged to the lower reaches of the river through the water outlet pipe 130. The water collecting tank 100 is connected to an aeration system, and the aeration system blows air from bottom to top in multiple water filtering areas.

[0041] The top opening of the water filter area is provided with a floating carrier 140 that floats up and down and is in the shape of a sheet. The floating carrier 140 is provided with a plurality of circular through holes 141. A rotatably arranged convex cup 150 is sleeved in the through hole 141. The convex cup 150 is rotatably connected to the floating carrier 140 and extends to the bottom of the floating carrier 140. The convex cup 150 has a cup cavity with a top opening. The circumference and bottom of the convex cup 150 are respectively provided with a plurality of root system holes.

[0042] The cup cavity is filled with a matrix mixed with biochar, and plants are planted in the matrix. The roots of the plants pass through multiple root holes and extend to the outside of the cup cavity; a plurality of blades 151 are protruding outward from the circumferential side of the convex cup 150, and the plurality of blades 151 are arranged at intervals along the circumferential side of the convex cup 150. During the flow of the receiving water body, the blades 151 on the circumferential side of the convex cup 150 are impacted, driving the plurality of convex cups 150 to rotate.

[0043] The low-energy ecological floating bed device for improving the water quality of a small-scale receiving water body in the water transfer project provided above, through the setting of multiple grid plates 110 and the water filtration area, the receiving water body undergoes multi-stage filtration and purification during the flow process, effectively removing pollutants such as suspended matter in the water and improving the water quality. The matrix mixed with biochar filled in the cup cavity provides a good growth environment for microorganisms. The microorganisms form a biofilm on the surface of the matrix and around the root holes, participate in the biological purification process of the water body, and further enhance the water purification effect. The water body is purified by combining plants with the matrix mixed with biochar to reduce the impact of seasonal changes.

[0044] The root holes not only allow the plant roots to pass through and extend to the outside of the cup cavity, but also provide another attachment point for microorganisms. The plant roots secrete some substances during their growth, which can attract and promote the attachment and growth of microorganisms around the roots, thereby further enhancing the formation of biofilm and purification effect.

[0045] The design of the floating carrier 140 and the convex cup 150 enables the device to have an ecological floating bed function, thereby increasing the ecological diversity of the water body and providing a space for aquatic organisms to inhabit and reproduce.

[0046] The solar energy system is used to increase the power supply and realize low-carbon and environmental protection. The aeration system is used to provide breathing oxygen for microorganisms and plant roots in the floating bed ecosystem, providing an important driving force for improving the quality of raw water.

[0047] Specifically, the solar energy system includes a solar panel 210 and a battery. The electric energy converted by the solar panel 210 is stored in the battery. The water inlet pipe 120 is connected to a pump 121 that pumps the receiving water in the river channel to the water inlet area. The battery provides electric energy for the pump 121.

[0048] The solar panel 210 is connected to a longitudinally arranged bracket 200, on which a swing head 220 swinging in space and a sensor 230 for monitoring the angle of sunlight are provided. The solar panel 210 is connected to the swing head 220, which drives the solar panel 210 to swing so that sunlight directly shines on the solar panel 210.

[0049] Specifically, the rear side of the solar panel 210 is connected to the swing head 220 via a hinge shaft 211 , a convex tooth is provided in the middle of the hinge shaft 211 , a rotatably arranged gear 221 is provided in the swing head 220 , and the gear 221 meshes with the convex tooth.

[0050] The aeration system includes an aerator 300 and a plurality of air pipes 310 correspondingly arranged at the bottom of the water filter area, the battery provides power to the aerator 300, and the plurality of air pipes 310 are respectively connected to the aerator 300;

[0051] The upper part of the air pipe 310 is provided with a plurality of upper air ports 311 arranged upward, and the two sides of the lower part of the air pipe 310 are respectively provided with a plurality of lower air ports 312 arranged downward, and the plurality of upper air ports 311 and the plurality of lower air ports 312 are respectively arranged at intervals along the axial direction of the air pipe 310;

[0052] The air pipe 310 is connected to the bottom of the water filter area through a plurality of elastic bands 320. When the air pipe 310 is not injected with high-pressure gas, the elastic bands 320 are in a relaxed state, and the air pipe 310 is placed at the bottom of the water filter area. When the air blower 300 injects high-pressure gas into the air pipe 310, the high-pressure gas is ejected outward through a plurality of upper air ports 311 and a plurality of lower air ports 312, respectively, driving the air pipe 310 to float up and down in the water filter area, and the elastic bands 320 are in a reciprocating expansion and contraction state. In this way, the gas is ejected outward through the upper air ports 311 and the lower air ports 312. This ejection action not only increases the turbulence of the water body, but also promotes the mixing and convection of the water body in the water filter area. This helps to distribute the dissolved oxygen more evenly throughout the water body, thereby improving the utilization efficiency of oxygen. This increases the contact area between the gas and the water body, which is more conducive to the transfer of oxygen into the water body, thereby improving the aeration efficiency.

[0053] The air pipe 310 is provided with a plurality of inflation ports and a plurality of airbag bags 330, and the plurality of airbag bags 330 are arranged corresponding to the plurality of inflation ports and are connected to the inflation ports; when the blower 300 injects high-pressure gas into the air pipe 310, the airbag bags 330 are in an expansion and contraction state driven by the expansion of the high-pressure gas and the reverse compression of the receiving water body, driving the air pipe 310 to float up and down. In this way, the airbag bags 330 are expanded by the expansion of the high-pressure gas, and then contract under the reverse compression of the receiving water body. This expansion and contraction state not only makes the air pipe 310 float up and down in the water filtration area, but also increases the contact area and contact time between the gas and the water body, thereby improving the aeration efficiency. Dynamic aeration can more effectively transfer oxygen to the water body than static aeration, and promote the increase of dissolved oxygen content in the water body.

[0054] The floating bed carrier is provided with a plurality of hollow holes of different shapes that penetrate up and down, and the plurality of hollow holes are arranged between adjacent through holes 141; the bottom of the floating bed carrier is provided with a plurality of longitudinally arranged and elastic bottom diaphragms 160, and the bottom diaphragms 160 are arranged around the circumference of the hollow holes, and the upper end of the bottom diaphragm 160 is docked at the bottom of the floating bed carrier, and the lower end of the bottom diaphragm 160 is arranged to extend downward. In this way, firstly, the design of the hollow holes allows the water to freely pass through the floating bed carrier, increasing the contact area between the water and the air, thereby promoting the dissolved oxygen content in the water. This is crucial for improving water quality and promoting the respiration and metabolic activities of aquatic organisms.

[0055] Next, the bottom membrane 160 is arranged around the hollow hole, and its elastic characteristics help to produce small disturbances when the water flows, further enhancing the effect of water exchange. At the same time, the elastic design of the bottom membrane 160 can increase the stability of the floating bed carrier in the water and reduce the risk of shaking and capsizing caused by water flow fluctuations.

[0056] Moreover, the hollow holes not only provide a channel for water exchange, but also provide space for microorganisms to attach and reproduce. Microorganisms can attach to the inner wall of the hollow holes and the surface of the bottom membrane 160 to form a biofilm. This biofilm can absorb, degrade and transform pollutants in the water, such as nitrogen, phosphorus and other nutrients, thereby purifying the water quality.

[0057] An annular gap is formed between the outer periphery of the floating bed carrier and the outer periphery of the top opening. Along the direction in which the bottom diaphragm 160 extends downward, the thickness of the bottom diaphragm 160 gradually decreases, and the bottom diaphragm 160 is arranged in multiple sections of bending; during the flow of the receiving water in the filtration area, the bottom diaphragm 160 is impacted, driving the floating bed carrier to move back and forth at the top opening. In this way, as the water flows, the bottom diaphragm 160 is impacted and produces slight deformation and vibration. This dynamic response further promotes the turbulence and mixing of the water around the floating bed carrier, which helps the diffusion of dissolved oxygen and the diffusion and dilution of pollutants. The reciprocating movement of the floating bed carrier and the dynamic response of the bottom diaphragm 160 help to improve the growth environment of plants on the floating bed. By promoting water exchange and the diffusion of dissolved oxygen, more oxygen and nutrients are provided to the plant roots. At the same time, this dynamic environment also helps to reduce the entanglement and knotting of plant roots during growth.

[0058] The inner wall of the hollow hole is provided with a transparent annular diaphragm 170, which is arranged to extend along the circumference of the hollow hole. The outer side of the annular diaphragm 170 is docked with the inner wall of the hollow hole, and the inner side of the annular diaphragm 170 is bent and extended upward, and the inner side of the annular diaphragm 170 surrounds the hollow middle area.

[0059] A plurality of bottom edges 400 are convexly provided at the bottom of the water cavity, and the plurality of bottom edges 400 are aligned with the plurality of grid plates 110 in correspondence with each other, and the bottom edges 400 are arranged between adjacent filtering areas; a mounting groove is provided at the top of the bottom edge 400, and the mounting groove is extended along the length direction of the bottom edge 400;

[0060] An elastically deformable airbag strip 410 is provided at the bottom of the installation groove, and the airbag strip 410 is arranged to extend along the length direction of the installation groove, and the bottom of the grille plate 110 is fixedly connected to the top of the airbag strip 410; hollow strips are respectively provided on both sides of the bottom edge 400, and the hollow strips are arranged to extend along the length direction of the bottom edge 400, and the installation groove is connected to the outside through the hollow strips, and both sides of the airbag strip 410 extend into the hollow strips;

[0061] When the receiving water flows in the filtration area, the receiving water impacts the side of the airbag strip 410 through the hollow strip, driving the top of the airbag strip 410 to bulge upward and deform, driving the grid plate 110 to float upward, and the bottom of the grid plate 110 remains in the installation groove. In this way, the grid plate 110 floats, increasing its contact area with the water body, which is conducive to better intercepting and removing suspended matter, impurities, etc. in the water body, thereby improving the filtration efficiency.

[0062] The water inlet pipe 120 extends to the lower part of the water inlet area, and the water outlet pipe 130 is connected to the upper part of the water outlet area. The water outlet pipe 130 is connected to a drainage pump for pumping the purified water in the water outlet area to the water outlet pipe 130 for discharge; the water outlet pipe 130 has an extension section extending into the water outlet pipe 130, the extension section is arranged in a spiral shape, and extends from top to bottom to the middle of the water outlet area, the end of the extension section is arranged in a closed manner, and a plurality of water outlet holes for the purified water to enter the water outlet pipe 130 are arranged around the extension section. In this way, a plurality of water outlet holes are arranged around the extension section, and this design helps to prevent the blockage of the water outlet pipe 130. Even if a water outlet hole is blocked by impurities, other water outlet holes can still work normally to ensure the smooth discharge of the purified water.

[0063] The water inlet pipe 120 extends to the lower part of the water inlet area, which helps to make fuller use of the space in the water inlet area, so that the water to be purified can enter the purification system more evenly, which helps to reduce the retention time of the water in the water inlet area and improve the purification efficiency.

[0064] The extension section on the water outlet pipe 130 is arranged in a spiral shape and extends from top to bottom to the middle of the water outlet area. This design increases the contact area between the water outlet pipe 130 and the purified water in the water outlet area. Through the arrangement of multiple water outlet holes, the purified water can enter the water outlet pipe 130 more evenly, thereby improving the collection efficiency of the purified water.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
