Description

Technical Field

[0001] The present invention relates to the technical field of ecological water body treatment, and in particular to a water purification ecological floating island device for treating black and odorous water bodies. Background Art

[0002] As we all know, the treatment of black and odorous water bodies involves multiple links such as pollution source control, water quality improvement, ecological restoration and long-term management. Ecological floating islands are sometimes used for the ecological treatment of different water environments. For eutrophic water quality, efficient artificial ecosystems with aquatic plants as the main body are established using the principles of ecological engineering to reduce the pollution load in water bodies.

[0003] The existing technology has the following problems: when using ecological floating islands for water treatment, their own treatment capacity is relatively limited. In addition, over a long period of use, the decaying organic matter caused by excessive pollution in black and odorous water may wrap or entangle the roots of ecological plants, making it difficult to treat them normally. In addition, the functions of the ecological floating islands in the existing technology are relatively simple.

[0004] Based on the above-mentioned situation, we propose a water purification ecological floating island device for the treatment of black and odorous water bodies, which can collect solid pollutants or flocculent pollutants in the water body for later treatment, provide living space for fish in the water body, reduce the direct impact of pollutants on the ecological floating island, and improve the water purification efficiency. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In response to the shortcomings of the existing technology, the present invention provides a water purification ecological floating island device for the treatment of black and odorous water bodies. It has the advantages of collecting solid pollutants or flocculent pollutants in the water body for subsequent treatment, providing a living space for fish in the water body, reducing the direct impact of pollutants on the ecological floating island, and improving the water purification efficiency.

[0007] (2) Technical solution

[0008] The above technical objectives of the present invention are achieved through the following technical solutions: a water purification ecological floating island device for treating black and odorous water bodies, comprising six planting platforms, a floating frame and an anchor reef, wherein the six planting platforms are movably connected, a suspended reef is provided on the top of the anchor reef, an upper connecting cable is installed on the top of the suspended reef, the top of the upper connecting cable is assembled with the bottom of the planting platform, and a partition net is sewn between the upper connecting cables;

[0009] The planting platform includes a carrier plate, the bottom of the inner side of the carrier plate is filled with a filler layer, the inner side of the carrier plate is fixedly connected to a partition frame, the top of the filler layer is provided with a matrix layer, the outer side of the carrier plate is fixedly connected to a clamping frame, the inner side of the clamping frame is bolted to a floating plate, and the top of the matrix layer is planted with emergent plants;

[0010] The floating reef includes a bottom ring, the top of the bottom ring is fixedly connected to an inclined guide plate, the top of the inclined guide plate is fixedly connected to a top frame, a filter cartridge is provided between the top frame and the bottom ring, the outer side of the filter cartridge is fixedly connected to a winding rod, and the outer side of the winding rod is provided with an integrally formed scraper.

[0011] The above technical solution is adopted to plant emergent plants by setting up planting platforms. The plants have well-developed root systems and strong ability to absorb nitrogen and phosphorus. The plants are higher than the water surface and planted in the substrate layer. Due to the obstruction of the filler layer, the water that contacts the plant roots will be initially filtered through the filler in the filler layer. The set clamping frame cooperates with the float plate to provide buoyancy so that the entire carrier plate can be located on the water surface. The set floating frame is used to limit the six planting platforms. When a large deformation displacement occurs between the six planting platforms, it will contact the inner floating frame and be restricted. By setting up anchor reefs, in addition to serving as a habitat for fish in the water body, it can also be used as a counterweight to stabilize the relative position of the device. The suspended reef is used to provide a habitat for fish in the middle of the water body. When water passes through the suspended reef, it is restricted by the obstruction of the inclined guide vanes, and larger materials cannot enter it, while flocculent impurities will flow along the inclined guide vanes to the outside of the filter cartridge. Since the external openings of some inclined guide vanes are large and the internal openings are small, the impurities that enter are difficult to escape from the suspended reef. When the flocculent impurities contact the winding rod, they will be caught by the external scrapers and entangled on the outside of the winding rod. During periodic maintenance, the suspended reef can be opened and the internal filter cartridge can be replaced or replaced. The upper connecting rope on the top of the suspended reef is used to anchor and limit the planting platform, and the partition net is installed at the same time. The setting of the partition net can prevent solid impurities from entering the bottom of the planting platform and adhering to the surface of the carrier plate, affecting the normal purification of the plants.

[0012] The present invention is further configured as follows: connecting ears are fixedly connected on both sides of the planting platform, a connecting plate is provided at the bottom of the connecting ear, a hand screw is sleeved on the inner side of the connecting ear, and the outer side of the hand screw is threadedly connected to the connecting plate.

[0013] By adopting the above technical solution, by setting connecting ears and connecting plates, when connecting the planting platforms, the connecting plate can be clamped at the bottom of the connecting ear, and screwed into the connecting plate by hand to prevent the structure from loosening, so that there is a certain displacement space between the planting platforms. When the structure collides, a certain amount of displacement occurs to avoid damage to the structure.

[0014] The present invention is further configured as follows: the anchor reef is a hemisphere made of limestone, and holes are opened on the inner side of the anchor reef.

[0015] By adopting the above technical solution, by setting up a hemispherical anchor reef, algae, microorganisms, etc. can attach to the surface of the sphere and the holes to form a biofilm, providing a food source for fish. The holes provide a habitat and breeding place for fish, and can effectively disturb the water flow, increase the dissolved oxygen in the water, and make the nutrients more evenly distributed.

[0016] The present invention is further configured as follows: the filler layer is made of volcanic rock material, the matrix layer is made of solidified fiber soil material, a plurality of through holes are opened on the inner side of the carrier plate, the front side of the top of the carrier plate is rotatably connected to a limiting iron frame through a hinge, and the rear side of the limiting iron frame and the rear side of the carrier plate are snap-connected.

[0017] The above technical solution is adopted, by setting a matrix layer made of solidified fiber soil material, which has both water retention and air permeability and microbial attachment ability, and can directly fix the plant roots, avoiding the problem of easy loss of traditional floating island matrix, and at the same time avoiding looseness. The through holes opened in the carrier plate can provide water for soaking the plant roots. In addition, the solidified fiber soil material is made of polymer materials, carbon mud, straw, cotton and other agricultural and forestry wastes, as well as plant residues, expanded perlite and other raw materials through high temperature extrusion and processing. Straw, cotton, plant residues, etc. are rich in nutrients, which are beneficial to the growth of plants. The addition of polymer materials improves the solidified fiber soil material. The bonding strength between the raw material components in the material is improved, and its overall stability is improved, so that the solidified fiber soil material is not easy to loosen. At the same time, the expanded perlite contained in the material increases the porosity of the solidified fiber soil material and reduces the overall density, making it easy to float on the water surface. It is also beneficial to the respiration of plant roots and the activity of microorganisms, thereby promoting the growth of plants. Moreover, during high-temperature extrusion, the insect eggs in the raw materials can be killed, providing a good environment for plant growth. At the same time, by processing the solidified fiber soil material into a block-shaped matrix layer, placing it in a carrier tray, and fixing it with a limiting iron frame, the matrix layer can be prevented from floating out of the carrier tray.

[0018] The present invention is further configured as follows: a plurality of long grooves are provided on the inner side of the filter cartridge, an assembly ring is fixedly connected to the top of the filter cartridge, a positioning rod is fixedly connected to the inner side of the top frame, an integrally formed protrusion is provided at the bottom of the positioning rod, a groove is provided on the top of the assembly ring for use with the protrusion, and the protrusion is inserted into the inner side of the groove.

[0019] By adopting the above technical solution, a long groove is provided for water circulation, and an assembly ring is provided to cooperate with the positioning rod. When replacing or installing the filter cartridge, the protrusion of the positioning rod can be inserted into the groove to complete the initial fixed limit.

[0020] The present invention is further configured as follows: a bottom ear is provided on the outer side of the bottom ring, the bottom of the bottom ring is movably connected to an end cover, two integrally formed positioning rings are provided on the top of the end cover, the inner positioning ring is clamped on the inner side of the bottom of the filter cartridge, and the outer positioning ring is clamped on the inner side of the bottom ring, and a mating ear is provided on the outer side of the end cover, and the bottom ear and the mating ear are installed by bolts and nuts.

[0021] By adopting the above technical solution and setting an end cover, when it is necessary to replace the filter cartridge or install the filter cartridge, the end cover can be removed from the bottom of the bottom ring by removing the bolts and nuts, so that the internal filter cartridge can be removed for cleaning or replacement. By setting a positioning ring, the position of the end cover relative to the bottom ring can be limited, and the filter cartridge can be prevented from being displaced.

[0022] The present invention is further configured as follows: an air pump and a water pump are installed on the top of the floating frame, the exhaust end of the air pump is fixedly connected to a hose, a distribution pipe is installed at the bottom of the hose, the top of the distribution pipe is fixedly connected to a connecting frame, and the top of the connecting frame is fixedly connected to the floating frame.

[0023] By adopting the above technical solution, an air pump is set up to extract gas from the environment and pump it to the distribution pipe through a hose. After the airflow is released, the bubbles are fully mixed with the water during the rising process, dissolving the oxygen in the air into the water, and at the same time promoting water circulation, enhancing the fluidity of the water body, and inhibiting the reproduction of anaerobic microorganisms, thereby improving the black and smelly phenomenon.

[0024] The present invention is further configured as follows: the input end and the output end of the water pump are fixedly connected with a suction pipe and a discharge pipe respectively, the suction pipe is arranged on the inner side of the filter cartridge, and the discharge pipe is arranged on the top of the distribution pipe.

[0025] By adopting the above technical solution, a water pump is set up to generate negative pressure at the suction pipe and discharge it from the discharge pipe. The water flow discharged from the discharge pipe will wash away the impurities attached to the surface of the screen, and the part that generates negative pressure is located at the filter cartridge, which can draw the water in the surrounding environment into the suspended reef to facilitate the collection of impurities in the surrounding water.

[0026] The present invention is further configured as follows: a photovoltaic panel is installed on the top of the floating frame, and a controller, a battery and an inverter are installed on the top of the floating frame.

[0027] By adopting the above technical solution, by setting up photovoltaic panels in conjunction with controllers, batteries and inverters, the surface of the empty water body can be used as a space for photovoltaic power generation, and the stored electricity can be used to power electronic components.

[0028] The present invention is further configured as follows: the bottom of the clamping frame and the top of the top frame are fixedly connected with binding rings, the two ends of the upper connecting rope are bolted to the top binding ring and the bottom binding ring respectively, the top of the anchor reef and the bottom of the end cover are fixedly connected with anchor rings, and the two anchor rings are bolted together by anchor ropes.

[0029] By adopting the above technical solution, a binding ring is provided to cooperate with the upper connecting cable to connect or disassemble the clamp frame and the top frame. Similarly, the anchor ring is used in conjunction with the anchor cable to connect or disassemble the end cover and the anchor reef.

[0030] (3) Beneficial effects

[0031] Compared with the existing technology, the present invention provides a water purification ecological floating island device for treating black and odorous water bodies, which has the following beneficial effects:

[0032] The water purification ecological floating island device for the treatment of black and odorous water bodies is used to plant emergent plants by setting up planting platforms. The plants have well-developed root systems and strong nitrogen and phosphorus absorption capabilities. The plants are higher than the water surface and are planted in the substrate layer. Due to the obstruction of the filler layer, the water that contacts the plant roots will be initially filtered through the filler in the filler layer. The set clamping frame cooperates with the float plate to provide buoyancy so that the entire carrier plate can be located on the water surface. The set float frame is used to limit the six planting platforms between them. When a large deformation displacement occurs between the six planting platforms, they will contact the inner float frame and be restricted. By setting up anchor reefs, in addition to serving as a habitat for fish in the water body, it can also be used as a counterweight to stabilize the relative position of the device, and the suspended reef is used to provide a habitat for fish in the middle of the water body. When the water passes through the suspended reef, it is restricted by the obstruction of the inclined guide vanes, and larger materials cannot enter it, while flocculent impurities will flow along the inclined guide vanes to the outside of the filter cartridge. Since the external openings of some inclined guide vanes are large and the internal openings are small, the impurities that enter are difficult to escape from the suspended reef. When the flocculent impurities contact the winding rod, they will be caught by the external scrapers and entangled on the outside of the winding rod. During periodic maintenance, the personnel can open the suspended reef and replace the internal filter cartridge. The upper connecting rope on the top of the suspended reef is used to anchor and limit the planting platform, and the partition net is installed at the same time. The setting of the partition net can prevent solid impurities from entering the bottom of the planting platform and adhering to the surface of the carrier plate, affecting the normal purification of the plants.

[0046] By setting up a planting platform 1, emergent plants are planted. Their root systems are well-developed and their ability to absorb nitrogen and phosphorus is strong. The plants are above the water surface and planted in the substrate layer 104. Due to the obstruction of the filler layer 102, the water that contacts the plant roots will be initially filtered through the filler in the filler layer 102.

When the anchor 3 is connected, the anchor 3 can be fixed on the bottom of the anchor 3. The inner side of the body disc 101 is provided with a plurality of through holes. By providing a matrix layer 104 made of a solidified fiber soil material that has both water retention and air permeability and microbial attachment capabilities, it can directly fix plant roots, avoiding the problem of easy loss of traditional floating island matrices and preventing looseness. In addition, the solidified fiber soil material is composed of plant fibers such as straw and cotton stalks, natural soils such as sand and clay, and inorganic curing agents such as resin and lime, or organic curing agents such as microbial fluid and high molecular polymers. It has strong water retention and good air permeability. The pore structure formed by the fibers and curing agents in the solidified fiber soil has good capillary action, which can absorb and store large amounts of water. The water is evenly distributed within the soil, providing a continuous water supply for plant growth and reducing the internal temperature of the soil during high temperatures in summer. Its unique structure allows air to circulate freely in the soil, providing the necessary oxygen for plant root respiration and microbial activity in the soil, which is beneficial to plant growth and the balance of the soil ecosystem. Its light weight makes it easy to float on the water surface.By processing the solidified fiber soil material into a block-shaped matrix layer 104, placing it in the carrier plate 101, and fixing it with a limiting iron frame 20, the matrix layer 104 can be prevented from floating out of the carrier plate 101, and the through holes opened in the carrier plate 101 can be used for water to soak the plant roots. An air pump 14 and a water pump 15 are installed on the top of the floating frame 2.

After the airflow is released, the bubbles are fully mixed with the water during the rising process, dissolving the oxygen in the air into the water, and at the same time promoting water circulation, enhancing water The fluidity of the water body is improved, and the reproduction of anaerobic microorganisms is inhibited, thereby improving the black and smelly phenomenon. A photovoltaic panel 19 is installed on the top of the floating frame 2. A controller, battery, and inverter are installed on the top of the floating frame 2. By setting up the photovoltaic panel 19 in conjunction with the controller, battery, and inverter, the surface of the water body in the empty frame can be used as a space for photovoltaic power generation, and the stored electricity is used to provide energy for electronic components. The bottom of the clamping frame 105 and the top of the top frame 43 are fixedly connected with a binding ring. The two ends of the upper connecting cable 5 are bolted to the top binding ring and the bottom binding ring respectively. The top of the anchor reef 3 and the bottom of the end cover 12 are fixedly connected with an anchor ring. The two anchor rings are bolted together by an anchor cable. The binding ring is used to cooperate with the upper connecting cable 5 to connect or disconnect the clamping frame 105 and the top frame 43. Similarly, the anchor ring cooperates with the anchor cable to connect or disconnect the end cover 12 and the anchor reef 3.

[0048] Working principle of this embodiment: First, the planting platform 1 is movably connected through the connecting ears 7, connecting plates 8 and hand screws 9 on both sides to form a deformable floating island array. The floating frame 2 is placed in the center of the array to limit excessive displacement of the platform. The floating reef 4 is bolted to the binding ring at the top of the top frame 43 and the binding ring at the bottom of the planting platform 1 with the upper connecting cable 5.

The substrate layer 104 is used to plant emergent plants, and the roots contact the water through the holes of the carrier plate 101. The filler layer 102 filters and preliminarily purifies the water quality. The floating plate 106 is bolted to the inside of the clamping frame 105 to provide buoyancy for the planting platform 1, so that it floats on the water surface. The air pump 14 on the floating frame 2 is turned on, and the gas releases bubbles through the hose 16 and the distribution pipe 17 to achieve water aeration, oxygenation and circulation. After the water pump 15 is started, the water in the filter cartridge 44 of the suspended reef 4 is extracted through the suction pipe and sent to the distribution pipe 17 through the discharge pipe, flushing the screen 6 and promoting water circulation. The photovoltaic panel 19 converts solar energy into electrical energy, which is stored through the controller, battery and inverter to power the equipment.

When the water passes through the suspended reef 4, it is restricted by the obstruction of the inclined guide piece 42, and larger-sized materials cannot enter it, while flocculent impurities and the like will flow along the inclined guide piece to the outside of the filter cartridge 44. Since the external openings of the inclined guide pieces 42 are large and the internal openings are small, the impurities that enter are difficult to escape from the suspended reef 4. When the flocculent impurities contact the winding rod 45, they will be caught by the external scrapers and entangled on the outside of the winding rod 45.

When it is necessary to replace the filter cartridge 44 or install the filter cartridge 44, the end cover 12 can be removed from the bottom of the bottom ring 41 by removing the bolts and nuts, so that the internal filter cartridge 44 can be removed for cleaning or replacement. The positioning ring 13 can be used to limit the position of the end cover 12 relative to the bottom ring 41, and at the same time prevent the filter cartridge 44 from being displaced. The input and output ends of the water pump 15 are fixedly connected with a suction pipe and a discharge pipe respectively. The suction pipe is arranged on the inner side of the filter cartridge 44, and the discharge pipe is arranged at the top of the distribution pipe 17.
