Description

Technical Field

[0001] The invention relates to the technical field of ecological floating beds, in particular to a multifunctional ecological floating bed based on biological film formation to treat eutrophic water bodies. Background Art

[0002] Eutrophication is the process by which excessive nutrients (primarily nitrogen and phosphorus) enter the water, leading to the overgrowth of algae and other plankton, which consumes dissolved oxygen, thus affecting water quality and the health of aquatic ecosystems. Controlling eutrophication requires significant human and material resources. Ecological floating beds are one method of eutrophication control. Through absorption and adsorption by plant roots and species competition, they reduce nitrogen, phosphorus, and organic matter in eutrophic waters, thereby purifying the water.

[0003] Ecological floating beds generally consist of a floating bed structure, aquatic plant beds, aquatic plants, and underwater elements. While ecological floating beds have multiple functions, such as purifying water quality, increasing biodiversity, beautifying the landscape, and providing wave and bank protection, existing ecological floating beds are made up of multiple floating beds spliced ​​together and locked together with bolts. Waves in the water can cause the joints to shake and even bend, resulting in the overall floating bed being non-horizontal and the aquatic plants being grown at an angle. This not only affects its aesthetics, but in severe cases, the floating bed can fall apart and drift with the current, affecting flood safety. Furthermore, existing floating beds primarily utilize the water purification effects of aquatic plants. To increase dissolved oxygen in water and enhance the self-purification of water bodies, a multifunctional ecological floating bed based on biofilm treatment for eutrophic water bodies is proposed. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a multifunctional ecological floating bed based on biological film formation to treat eutrophic water bodies, so as to solve the technical problems raised in the above background.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a multifunctional ecological floating bed for treating eutrophic water bodies based on biofilm formation, comprising a frame, wherein frame assemblies are fixed at the front and rear edges of the bottom of the frame, and each set of the frame assemblies is equipped with multiple sets of floating plate assemblies;

[0006] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure of described sliding panel also is provided with an interlocking structure, and the interlocking structure of described sliding panel also is provided with an interlocking structure.

[0007] As an optimal technical solution, a channel connected to the boost chamber is opened at the bottom of the give way groove, and a follower rod passing through the channel and fixed to the top of the piston is fixed on the top of the connecting piece, and the outer wall diameter of the follower rod is smaller than the inner diameter of the channel.

[0008] As an optimal technical solution, a plurality of water inlet holes are reserved on the curved outer wall of the planting tube, and the bottom of the planting tube is in a grid shape.

[0009] As an optimal technical solution, a screw connected to a connecting piece is provided at the top of the partition beam, a follower bar extending to the outside of the floating frame is slidingly provided inside the partition beam, a base fixed to the upper surface of the follower bar is provided at the top of the screw, a base channel for the base to descend is provided at the top of the partition beam, and a travel groove is provided at the contact position between the partition beam and the floating frame and the follower bar.

[0010] As a preferred technical solution, two groups of photovoltaic panels are installed on the top of the frame near the left and right edges, and a battery pack for storing electrical energy is installed in the frame below the photovoltaic panels.

[0011] As an optimal technical solution, a double-headed motor is installed in the center position of the frame, and elliptical disks are installed at both ends of the double-headed motor. A base plate is installed under the double-headed motor, and the front and rear surfaces of the base plate are fixed to the end of each group of the extended follower bars.

[0015] The present invention adsorbs nitrogen and phosphorus in the water by adding biological fillers in the planting tube, which can also serve as a carrier for microorganisms, degrading organic matter in the water body, and achieving the goal of comprehensively repairing eutrophic water bodies. On the other hand, the waves generated on the surface of the water body are used to cause the plate body to float up and down, stirring the water body, transporting external air into the water, and increasing the dissolved oxygen in the water. This not only provides oxygen for the roots of the planted aquatic plants, which is beneficial to plant growth, but also helps to enhance the self-purification function of the water body and the degradation activity of aerobic microorganisms loaded on the biological fillers in the plant tube. When the water surface is calm, solar energy can also be used to actively drive the floating plate to rise and fall, enhancing the stirring effect of the water body and improving the flexibility, application and treatment effect of the floating bed.

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] A multifunctional ecological floating bed based on biological film treatment of eutrophic water bodies, such as Figures 1 to 8 As shown, it includes a frame body 100, and frame assemblies 200 are fixed at the front and rear edges of the bottom of the frame body 100, and multiple groups of floating plate assemblies 300 are assembled in each group of frame assemblies 200;

[0031] The frame assembly 200 includes two groups of floating frames 210. A plurality of partition beams 220 for limiting the floating plate assembly 300 are fixed at equal intervals between the front and rear surfaces of the two groups of floating frames 210. The floating plate assembly 300 includes a plate body 310 that is engaged between the two groups of partition beams 220. A clearance groove 311 is reserved on both sides of the plate body 310. Two groups of positioning rods 340 are longitudinally fixed in the clearance groove 311. The outer walls of the two groups of positioning rods 340 are slidably sleeved with connecting members 350 extending to the outside of the clearance groove 311. The upper and lower surfaces of the connecting members 350 are both provided with springs 341 sleeved on the outer walls of the positioning rods 340. A positioning groove 330 is formed at the top of the plate body 310. A planting tube 320 extending to the bottom of the plate body 310 is mounted in the positioning groove 330. A pressurizing chamber 390 is formed inside the plate body 310. A piston 391 is slidably mounted inside the pressurizing chamber 390. An air jet ring 370 is provided below the bottom of the planting tube 320. An air supply pipe 372 connected to the pressurizing chamber 390 is provided on the curved outer wall of the air jet ring 370. An air inlet pipe 373 connected to the pressurizing chamber 390 is provided at the top of the plate body 310. Several groups of nozzles 371 are inclined near the center of the outer wall of the air jet ring 370.

[0032] A channel is formed at the bottom of the clearance groove 311 and communicates with the pressurizing chamber 390. A driven rod 360 is fixed to the top of the connecting member 350 and passes through the channel and is fixed to the top of the piston 391. The outer diameter of the driven rod 360 is smaller than the inner diameter of the channel.

[0033] A screw rod 230 connected to the connecting piece 350 is provided at the top of the partition beam 220, and a follower bar 160 extending to the outside of the floating frame 210 is slidingly provided inside the partition beam 220. A base 231 fixed to the upper surface of the follower bar 160 is provided at the top of the screw rod 230. A base channel for the base 231 to descend is provided at the top of the partition beam 220, and a travel groove 240 is provided at the contact position between the partition beam 220 and the floating frame 210 and the follower bar 160.

[0034] When multiple groups of floating plate assemblies 300 are spliced ​​one by one inside the floating frame 210, the connectors 350 on both sides are sleeved on the outer wall of the screw 230 and locked with threads. At the same time, a certain amount of biological filler (filler adsorbent such as biochar, clay, or fly ash) is added to the planting tube 320. At the same time, plants (such as radix schoenopsis, calamus, canna, water lily, money grass, water lily, calamus, etc. suitable for the local area) are planted on top of the biological filler in the planting tube 320. This can achieve the combined functions of absorption, utilization, degradation and biological absorption of nitrogen and phosphorus in eutrophic water bodies.

[0035] When waves appear in the water, the plate 310 will float up and down on the two groups of beams 220. When it moves upward, the positioning rod 340 will move along the constraint direction of the connecting piece 350, compressing and stretching the springs 341 at the upper and lower parts of the connecting piece 350, generating a reset force for the plate 310 when it descends. Since the connecting piece 350 is fixed to the top of the beam 220, the piston 391 moves up and down in the pressurizing chamber 390 through the action of the driven rod 360, and the outside air can be drawn into the pressurizing chamber 390 through the air inlet pipe 373, and then transported to the jet ring 370 through the air supply pipe 372, and finally passed through the nozzle 371. The spray is directed to the bottom of the planting tube 320 to provide oxygen to the plants planted inside so that they can survive better. On the contrary, when the surface of the water body is relatively calm, the double-headed motor 120 can be controlled by the remote terminal to drive the driven bar 160 to move back and forth downward, and the plate body 310 is driven to descend through the screw 230 and the connecting piece 350. The water body generates buoyancy on the plate body 310 and cooperates with each other to achieve mutual movement between the plate body 310 and the connecting piece 350, thereby prompting the outside air to enter the boosting chamber 390, and finally achieving the purpose of supplying oxygen to the plant roots and microorganisms loaded on the biological filler in the water body and the planting tube 320.

[0036] Please refer to Figure 3 and Figure 4 The curved outer wall of the planting tube 320 is provided with multiple groups of water inlet holes, and the bottom of the planting tube 320 is in a grid shape.

[0037] Biological fillers can be added to the planting tube 320, which can not only absorb nitrogen and phosphorus in the water body, but also serve as carriers of microorganisms to achieve the degradation of organic matter in the water body.

[0038] Please refer to Figure 1 、 Figure 6 and Figure 7 Two sets of photovoltaic panels 110 are installed on the top of the frame 100 near the left and right edges, and a battery pack for storing electrical energy is installed inside the frame 100 below the photovoltaic panels 110;

[0039] A double-headed motor 120 is installed at the center of the frame 100, and an elliptical disk 130 is installed at both ends of the double-headed motor 120. A bottom plate 150 is installed under the double-headed motor 120. The front and rear surfaces of the bottom plate 150 are fixed to the ends of each group of extended follower bars 160. The top of the follower bar 160 is equipped with a roller 140 that contacts the curved outer wall of the elliptical disk 130.

[0040] The photovoltaic panel 110 receives sunlight to generate electricity, which is then transmitted to the inside of the battery pack to provide power for the double-headed motor 120. In response to the calm state of the water surface, the elliptical disk 130 reciprocates to squeeze the roller 140, causing the bottom plate 150 to drive the driven bar 160 to rise and fall back and forth, thereby supplying oxygen to the planted plants such as cereus, calamus, and canna.

[0041] Please refer to Figure 3 、 Figure 4 and Figure 5 The bottom of the plate 310 is located at the edge of the positioning groove 330 and has multiple groups of scrapers 380 fixed in a ring array. The scrapers 380 are in contact with the curved outer wall of the planting tube 320.

[0042] Before replacing the plant in the planting tube 320, external force is applied to the planting tube 320 to rotate it along the axis of the positioning groove 330, and the scraper 380 is used to cut off the rhizomes extending outside the planting tube 320, so that the planting tube 320 can be taken out and the plant planted inside can be replaced with less effort.

[0043] Please refer to Figure 2 The end of the nozzle 371 is equipped with a first one-way valve, and the end of the air inlet pipe 373 is located on the upper surface of the plate body 310 and is provided with a second one-way valve.

[0044] When the piston 391 is lowered, the first one-way valve is in an open state, and the second one-way valve is in a closed state. The air inside the boost chamber 390 can be transported to the jet ring 370 through the air supply pipe 372, and finally discharged through the nozzle 371 to provide oxygen to the bottom of the planting tube 320. Conversely, the first one-way valve is in a closed state, and the second one-way valve is in an open state, and the outside air can be drawn into the boost chamber 390 to prepare for the next oxygen supply to the roots of the plants.

[0045] During use, when waves appear in the water, the plate body 310 will float up and down between the two groups of partition beams 220. When it moves upward, its positioning rod 340 will move along the constraint direction of the connecting piece 350, compressing and stretching the springs 341 at the upper and lower parts of the connecting piece 350, generating a restoring force for the plate body 310 when it descends. Since the connecting piece 350 is fixed to the top of the partition beam 220, the piston 391 is moved up and down in the pressurizing chamber 390 through the action of the driven rod 360, and the outside air can be drawn into the pressurizing chamber 390 through the air inlet pipe 373, and transported to the jet ring 370 through the air supply pipe 372, and finally sprayed to the bottom of the planting tube 320 through the nozzle 371. The double-headed motor 120 can be controlled by a remote terminal to drive the driven bar 160 to move back and forth, and the plate 310 is driven to descend through the screw 230 and the connector 350. The water body generates buoyancy on the plate 310, and the plate 310 and the connector 350 move relative to each other, thereby promoting the outside air to enter the boosting chamber 390, and finally achieving the purpose of supplying oxygen to the plant roots in the planting tube 320 and the microorganisms on the biological filler carrier.

[0046] The remote-controlled double-headed motor 120 involved therein is implemented using existing technology.

[0047] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
