Description

Technical Field

[0001] This invention patent relates to the technical field of ecological floating bed devices, specifically to a low-energy-consumption ecological floating bed device for improving the water quality of small-scale receiving water bodies in water conveyance projects. Background Technology

[0002] Water conveyance projects refer to projects that transport water from a water source to a water-demanding area. In water conveyance projects, the small-scale receiving water body usually refers to the water body that the project passes through between its endpoint and the point of use. These water bodies may be affected by pollution, damage, or quality degradation.

[0003] In water transfer projects, the raw water generally meets the Class II water quality standard of the National Surface Water Quality Standard. However, after the water is transferred and enters the receiving area, the quality of the raw water may be affected by factors such as the background pollution of the sediment in each area, non-point source pollution in the surrounding area, particulate matter deposition and resuspension in the pipeline, and climate influence, and even eutrophication may occur.

[0004] In existing technologies, fixed artificial wetland systems or biofilters are set up along riverbanks to purify water through the synergistic effect of soil, plants, and microorganisms. Aquatic plants are planted within these systems to promote the natural purification process. Furthermore, water pumps are used to circulate the water and enhance the purification effect. However, traditional water purification facilities often rely on electrically driven pumps to achieve water circulation and flow, resulting in high energy consumption and difficulty in adapting to different seasonal needs. Summary of the Invention

[0005] The purpose of this invention is to provide a low-energy-consumption ecological floating bed device for improving the water quality of small-scale receiving water bodies in water conveyance projects, aiming to solve the problem of poor water quality in receiving water bodies in the prior art.

[0006] The present invention is implemented as follows: a low-energy ecological floating bed device for improving the water quality of a small-scale receiving water body in a water conveyance project, comprising a water collection tank and a solar energy system for providing power supply. The water collection tank has a water cavity for accommodating the receiving water body. The water collection tank is connected to an inlet pipe and an outlet pipe, which are respectively connected to the river channel for the flow of the receiving water body.

[0007] The water cavity is provided with multiple grid plates for receiving water to pass through and for filtering and purifying the receiving water. The multiple grid plates are arranged in sequence at intervals, dividing the water cavity into multiple water filtration zones arranged at intervals and having top openings. Along the flow direction of the receiving water in the water cavity, the multiple water filtration zones sequentially include an inlet zone, multiple intermediate zones and an outlet zone.

[0008] The inlet pipe is connected to the inlet area, and the outlet pipe is connected to the outlet area. The receiving water in the upstream of the river is discharged into the inlet area through the inlet pipe. The receiving water passes through the inlet area, multiple intermediate areas, and the outlet area in sequence to form purified water. The purified water is discharged to the downstream of the river through the outlet pipe. The water collection tank is connected to an aeration system, which blows air from bottom to top in multiple filtration areas.

[0009] The top opening of the filtration zone is provided with a floating carrier that floats up and down in a sheet shape. The floating carrier has multiple circular through holes, and a rotating cup is fitted in each through hole. The cup is rotatably connected to the floating carrier and extends to the bottom of the floating carrier. The cup has a cup cavity with a top opening, and multiple root holes are provided on the periphery and bottom of the cup.

[0010] The cup cavity is filled with a substrate mixed with biochar, and plants are planted in the substrate. The roots of the plants extend through multiple root pores to the outside of the cup cavity. Multiple blades are protruding outward from the periphery of the cup. The multiple blades are arranged at intervals along the periphery of the cup. When the receiving water flows, it impacts the blades on the periphery of the cup, driving the multiple cups to rotate.

[0011] Optionally, the solar energy system includes solar panels and batteries, with the electrical energy converted by the solar panels stored in the batteries; the water inlet pipe is connected to a pump that draws the receiving water from the river into the water inlet area, and the batteries provide power to the pump.

[0012] Optionally, the solar panel is connected to a longitudinally arranged support, which is equipped with a swing head that swings in space and a sensor that monitors the angle of sunlight. The solar panel is connected to the swing head, which drives the solar panel to swing so that sunlight shines directly on the solar panel.

[0013] Optionally, the aeration system includes an aerator and multiple air pipes correspondingly arranged at the bottom of the filtration zone, the battery provides power to the aerator, and the multiple air pipes are respectively connected to the aerator;

[0014] The upper part of the trachea is provided with multiple upward-facing air inlets, and the lower part of the trachea is provided with multiple downward-facing air inlets on both sides. The multiple upward air inlets and the multiple downward air inlets are arranged at intervals along the axial direction of the trachea.

[0015] The air tube is connected to the bottom of the filtration zone by multiple elastic bands. When no high-pressure gas is injected into the air tube, the elastic bands are in a relaxed state and the air tube is placed at the bottom of the filtration zone. When the blower injects high-pressure gas into the air tube, the high-pressure gas is sprayed outward through multiple upper air ports and multiple lower air ports, causing the air tube to float up and down repeatedly in the filtration zone, and the elastic bands are in a reciprocating expansion and contraction state.

[0016] Optionally, the air tube is provided with multiple inflation ports and multiple air bags, with the multiple air bags corresponding to the multiple inflation ports and connected to the inflation ports; during the process of the blower injecting high-pressure gas into the air tube, the air bags are in a state of expansion and contraction driven by the expansion of the high-pressure gas and the reverse compression driven by the receiving water, which drives the air tube to float up and down.

[0017] Optionally, the floating carrier has multiple irregularly shaped, through-holes arranged between adjacent through holes; the bottom of the floating carrier has multiple longitudinally arranged and elastic bottom membranes, which are arranged around the circumference of the holes, with the upper end of the bottom membranes abutting the bottom of the floating carrier and the lower end of the bottom membranes extending downwards.

[0018] Optionally, an annular gap is formed between the outer periphery of the floating carrier and the outer periphery of the top opening. Along the downward direction of the bottom membrane, the thickness of the bottom membrane gradually decreases, and the bottom membrane is arranged in multiple bends. During the flow of the receiving water in the filtration zone, it impacts the bottom membrane, driving the floating carrier to move back and forth at the top opening.

[0019] Optionally, the inner wall of the perforated hole is provided with a transparent annular membrane. The annular membrane extends circumferentially along the perforation of the perforation, with the outer side of the annular membrane abutting against the inner wall of the perforation. The inner side of the annular membrane bends upward and extends upward, and the inner side of the annular membrane surrounds and forms the perforated central area.

[0020] Optionally, the bottom of the water cavity is provided with a plurality of bottom ridges, which are arranged vertically aligned with the plurality of grid plates, and the bottom ridges are arranged between adjacent filter zones; the top of the bottom ridge is provided with a mounting groove, which extends along the length of the bottom ridge.

[0021] The bottom of the mounting groove is provided with an elastically deformable airbag strip, which extends along the length of the mounting groove, and the bottom of the grille plate is fixedly connected to the top of the airbag strip; the two sides of the bottom edge are respectively provided with hollow strips, which extend along the length of the bottom edge, and the mounting groove is connected to the outside through the hollow strips, and the two sides of the airbag strip extend into the hollow strips.

[0022] As the receiving water flows through the filtration zone, it impacts the sides of the airbag strips through the perforated strips, causing the top of the airbag strips to bulge upwards and deform, which in turn causes the grid plate to float upwards, while the bottom of the grid plate remains in the mounting groove.

[0023] Optionally, the inlet pipe extends to the lower part of the inlet area, and the outlet pipe is connected to the upper part of the outlet area. A drainage pump is connected to the outlet pipe to pump the purified water in the outlet area to the outlet pipe for discharge. The outlet pipe has an extension section extending into the outlet pipe. The extension section is arranged in a spiral shape and extends from top to bottom to the middle of the outlet area. The end of the extension section is closed. The periphery of the extension section is provided with multiple outlet holes for the purified water to enter the outlet pipe.

[0024] Compared with existing technologies, the low-energy-consumption ecological floating bed device for improving the water quality of small-scale receiving water bodies in water conveyance projects provided by this invention, through the setting of multiple grid plates and filtration zones, allows the receiving water to undergo multi-stage filtration and purification during flow, effectively removing suspended solids and other pollutants and improving water quality. The substrate mixed with biochar filling the cup cavity provides a good growth environment for microorganisms. Microorganisms form biofilms on the substrate surface and around the root pores, participating in the biological purification process of the water body and further enhancing the water purification effect. By combining plants with the biochar-mixed substrate to purify the water body, the impact of seasonal changes is reduced.

[0025] The root pores not only allow plant roots to pass through and extend outside the cup cavity, but also provide another attachment point for microorganisms. During growth, plant roots secrete substances that attract and promote the attachment and growth of microorganisms around the roots, thereby further enhancing biofilm formation and purification effects.

[0026] The design of the floating carrier and the convex cup enables the device to function as an ecological floating bed, which can increase the ecological diversity of the water body and provide space for aquatic organisms to inhabit and reproduce.

[0027] By increasing power supply through solar energy systems, low-carbon and environmentally friendly practices are achieved. The aeration system provides oxygen for the microorganisms and plant roots in the floating bed ecosystem, thus providing a crucial driving force for improving raw water quality.

[0037] Reference Figure 1-6 The image shown is a preferred embodiment of the present invention.

[0038] The present invention provides a low-energy ecological floating bed device for improving the water quality of a small-scale receiving water body in a water conveyance project, comprising a water collection tank 100 and a solar energy system for providing power. The water collection tank 100 has a water cavity for accommodating the receiving water body. The water collection tank 100 is connected to an inlet pipe 120 and an outlet pipe 130, respectively. The inlet pipe 120 and the outlet pipe 130 are respectively connected to the river channel for the flow of the receiving water body.

[0039] The water cavity is provided with multiple grid plates 110 for receiving water to pass through and for filtering and purifying the receiving water. The multiple grid plates 110 are arranged in sequence at intervals, dividing the water cavity into multiple water filtration zones with top openings. Along the flow direction of the receiving water in the water cavity, the multiple water filtration zones include an inlet zone, multiple intermediate zones and an outlet zone in sequence.

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

[0041] The top opening of the filtration zone is provided with a floating carrier 140 that floats up and down and is in the shape of a sheet. The floating carrier 140 has multiple circular through holes 141. A rotating cup 150 is fitted in the through hole 141. The cup 150 is rotatably connected to the floating carrier 140 and extends to the bottom of the floating carrier 140. The cup 150 has a cup cavity with a top opening. Multiple root holes are provided on the periphery and bottom of the cup 150.

[0042] The cup cavity is filled with a substrate mixed with biochar, and plants are planted in the substrate. The roots of the plants extend to the outside of the cup cavity through multiple root holes. Multiple blades 151 are protruding outward on the periphery of the cup 150. The multiple blades 151 are arranged at intervals along the periphery of the cup 150. When the receiving water flows, it impacts the blades 151 on the periphery of the cup 150, driving the multiple cups 150 to rotate.

[0043] The aforementioned low-energy-consumption ecological floating bed device for improving the water quality of small-scale receiving water bodies in water conveyance projects utilizes multiple grid plates 110 and filtration zones. During the flow of the receiving water, it undergoes multi-stage filtration and purification, effectively removing suspended solids and other pollutants, thus improving water quality. The biochar-mixed substrate filling the cup cavity provides an excellent growth environment for microorganisms. These microorganisms form a biofilm on the substrate surface and around the root pores, participating in the biological purification process and further enhancing the water purification effect. By combining plants with the biochar-mixed substrate for water purification, the impact of seasonal changes is reduced.

[0044] The root pores not only allow plant roots to pass through and extend outside the cup cavity, but also provide another attachment point for microorganisms. During growth, plant roots secrete substances that attract and promote the attachment and growth of microorganisms around the roots, thereby further enhancing biofilm formation and purification effects.

[0045] The design of the floating carrier 140 and the convex cup 150 enables the device to function as an ecological floating bed, which can increase the ecological diversity of the water body and provide space for aquatic organisms to inhabit and reproduce.

[0046] By increasing power supply through solar energy systems, low-carbon and environmentally friendly practices are achieved. The aeration system provides oxygen for the microorganisms and plant roots in the floating bed ecosystem, thus providing a crucial driving force for improving raw water quality.

[0047] Specifically, the solar energy system includes solar panels 210 and batteries, with the electrical energy converted by the solar panels 210 stored in the batteries; the water inlet pipe 120 is connected to a water pump 121 that pumps the receiving water in the river to the water inlet area, and the batteries provide power to the water pump 121.

[0048] The solar panel 210 is connected to a longitudinally arranged support 200. The support 200 is equipped with a swing head 220 that swings in space and a sensor 230 that monitors the angle of sunlight. The solar panel 210 is connected to the swing head 220, which drives the solar panel 210 to swing so that sunlight shines directly 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. The hinge shaft 211 has a tooth in the middle, and the swing head 220 has a rotating gear 221 that meshes with the tooth.

[0050] The aeration system includes an air blower 300 and multiple air pipes 310 arranged at the bottom of the filtration zone. The battery provides power to the air blower 300, and the multiple air pipes 310 are connected to the air blower 300 respectively.

[0051] The upper part of the trachea 310 is provided with multiple upward-facing air inlets 311, and the lower part of the trachea 310 is provided with multiple downward-facing air inlets 312 on both sides. The multiple air inlets 311 and multiple air inlets 312 are arranged at intervals along the axial direction of the trachea 310.

[0052] The air pipe 310 is connected to the bottom of the filtration zone via multiple elastic bands 320. When no high-pressure gas is injected into the air pipe 310, the elastic bands 320 are relaxed, and the air pipe 310 is positioned at the bottom of the filtration zone. When the aerator 300 injects high-pressure gas into the air pipe 310, the high-pressure gas is ejected outward through multiple upper air ports 311 and multiple lower air ports 312, causing the air pipe 310 to float up and down repeatedly within the filtration zone, while 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 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 within the filtration zone. This helps to distribute dissolved oxygen more evenly throughout the water body, improving oxygen utilization efficiency. It also increases the contact area between the gas and the water body, further facilitating oxygen transfer into the water, thereby improving aeration efficiency.

[0053] The air pipe 310 is equipped with multiple air inlets and multiple air bags 330, with the air bags 330 corresponding to and connected to the air inlets. During the process of the blower 300 injecting high-pressure gas into the air pipe 310, the air bags 330 are in a state of expansion and contraction driven by the expansion of the high-pressure gas and the reverse compression of the receiving water, causing the air pipe 310 to float up and down. Thus, the air bags 330 expand under the expansion of the high-pressure gas and then contract under the reverse compression of the receiving water. This expansion and contraction not only causes the air pipe 310 to float up and down in the filtration zone but also increases the contact area and contact time between the gas and the water, thereby improving aeration efficiency. Dynamic aeration is more effective than static aeration in transferring oxygen to the water, promoting an increase in dissolved oxygen content in the water.

[0054] The floating carrier has multiple irregularly shaped, through-holes arranged between adjacent through-holes 141. The bottom of the floating carrier has multiple longitudinally arranged, elastic bottom membranes 160, which are arranged circumferentially around the through-holes. The upper ends of the bottom membranes 160 are attached to the bottom of the floating carrier, and the lower ends extend downwards. This design allows water to flow freely through the floating carrier, increasing the contact area between the water and air, thereby promoting dissolved oxygen levels in the water. This is crucial for improving water quality and promoting the respiration and metabolic activities of aquatic organisms.

[0055] Next, the bottom diaphragm 160 is arranged around the perforated holes. Its elastic properties help to generate minor disturbances when the water flows, further enhancing the water exchange effect. At the same time, the elastic design of the bottom diaphragm 160 can increase the stability of the floating carrier in the water and reduce the risk of swaying and capsizing caused by water flow fluctuations.

[0056] Furthermore, the perforated structure not only provides a channel for water exchange but also offers space for microorganisms to attach and multiply. Microorganisms can attach to the inner wall of the perforated structure and the surface of the bottom membrane 160, forming a biofilm. This biofilm can absorb, degrade, and transform pollutants in the water, such as nutrients like nitrogen and phosphorus, thereby purifying the water.

[0057] An annular gap is formed between the outer periphery of the floating carrier and the outer periphery of the top opening. Along the downward direction of the bottom membrane 160, the thickness of the bottom membrane 160 gradually decreases, and the bottom membrane 160 is arranged in multiple bends. As the receiving water flows through the filtration zone, it impacts the bottom membrane 160, driving the floating carrier to reciprocate at the top opening. Thus, with the flow of water, the bottom membrane 160 experiences slight deformation and vibration due to the impact. This dynamic response further promotes turbulence and mixing of the water around the floating carrier, facilitating the diffusion of dissolved oxygen and the dilution of pollutants. The reciprocating movement of the floating carrier and the dynamic response of the bottom membrane 160 help improve the growth environment for plants on the floating bed. By promoting water exchange and dissolved oxygen diffusion, more oxygen and nutrients are provided to the plant roots. Simultaneously, this dynamic environment also helps reduce root entanglement and knotting during growth.

[0058] The inner wall of the perforated hole is provided with a transparent annular membrane 170. The annular membrane 170 extends along the circumference of the perforated hole. The outer side of the annular membrane 170 is connected to the inner wall of the perforated hole. The inner side of the annular membrane 170 bends upward and extends. The inner side of the annular membrane 170 surrounds and forms the perforated central area.

[0059] The bottom of the water chamber is provided with multiple bottom ridges 400, which are arranged vertically aligned with multiple grid plates 110. The bottom ridges 400 are arranged between adjacent filter zones. The top of the bottom ridge 400 is provided with an installation groove, which extends along the length of the bottom ridge 400.

[0060] The bottom of the mounting groove is provided with an elastically deformable airbag strip 410, which extends along the length of the mounting groove, and the bottom of the grille plate 110 is fixedly connected to the top of the airbag strip 410; the two sides of the bottom edge 400 are respectively provided with hollow strips, which extend along the length of the bottom edge 400, and the mounting groove is connected to the outside through the hollow strips, and the two sides of the airbag strip 410 extend into the hollow strips.

[0061] As the receiving water flows through the filtration zone, it impacts the sides of the airbag strips 410 via the perforated strips, causing the top of the airbag strips 410 to bulge upwards and deform, thus lifting the grid plate 110 upwards while keeping its bottom in the mounting groove. This floating mechanism of the grid plate 110 increases its contact area with the water, which helps to better intercept and remove suspended solids and impurities from the water, thereby improving filtration efficiency.

[0062] The inlet pipe 120 extends to the lower part of the inlet area, and the outlet pipe 130 is connected to the upper part of the outlet area. A drain pump is connected to the outlet pipe 130 to draw purified water from the outlet area into the outlet pipe 130 for discharge. The outlet pipe 130 has an extension section extending into the outlet area, which is arranged in a spiral shape and extends from top to bottom to the middle of the outlet area. The end of the extension section is closed, and multiple outlet holes are provided around the periphery of the extension section for purified water to enter the outlet pipe 130. This design, with multiple outlet holes around the periphery of the extension section, helps prevent clogging of the outlet pipe 130. Even if one outlet hole is blocked by impurities, the other outlet holes can still function normally, ensuring the smooth discharge of purified water.

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

[0064] The extension section on the outlet pipe 130 is arranged in a spiral shape and extends from top to bottom to the middle of the outlet area. This design increases the contact area between the outlet pipe 130 and the purified water in the outlet area. With the setting of multiple outlet holes, the purified water can enter the 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 within the protection scope of the present invention.
