Description

Technical Field

[0001] This utility model relates to the field of ecological purification technology, specifically to a self-powered ecological purification device for coordinated above-water and underwater restoration. Background Technology

[0002] With the development of my country's economy and society, lakes, rivers, and landscape water bodies are generally facing eutrophication pollution problems, leading to frequent algal blooms, decreased water transparency, and dissolved oxygen deficiency, thus disrupting the balance of aquatic ecosystems and landscape functions. Therefore, developing efficient, low-cost, and eco-friendly water remediation technologies has become an important issue in the field of environmental protection.

[0003] Currently, commonly used water remediation technologies mainly include physical, chemical, and ecological methods. Physical methods (such as artificial aeration and sediment dredging) are effective quickly, but they are usually energy-intensive, costly, and prone to secondary pollution. Chemical methods (such as adding chemicals) may leave chemical residues, posing potential risks to aquatic organisms. In contrast, ecological restoration technologies, especially artificial floating island technology, are widely used due to their low cost, environmental friendliness, and aesthetic benefits. Traditional artificial floating islands involve planting aquatic plants on a floating carrier, utilizing the plant roots to absorb nutrients such as nitrogen and phosphorus from the water. Simultaneously, the biofilm formed by the roots enriches microorganisms, further degrading pollutants.

[0004] However, some improved floating islands now integrate underwater aeration equipment. But these devices typically require mains power or rely on large-capacity batteries, leading to problems such as difficult wiring, limited energy resources, and high operating costs. This significantly restricts their application in remote areas, waters without power supply, or those requiring long-term stable operation. Utility Model Content

[0005] In order to overcome the problems existing in the background technology, this utility model provides a self-powered ecological purification device for coordinated above-water and underwater restoration, so as to solve the technical problems mentioned in the background technology that the current aeration equipment needs to be connected to the mains power, resulting in limited energy and high operating costs.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A self-powered ecological purification device for coordinated above-water and underwater restoration includes a floating plate 1. A planting pot 2 is connected to the bottom of the floating plate 1, and an opening 3 at the top of the floating plate 1 communicating with the interior of the planting pot 2. A blower 4, a storage battery 5, a solar charging panel 6, and a small wind turbine 7 are installed on the top of the floating plate 1. The solar charging panel 6 and the small wind turbine 7 are connected to the storage battery 5 to input solar power and wind power into the storage battery 5. The storage battery 5 is electrically connected to the blower 4 to provide power for the blower 4 to work. The air outlet of the blower 4 is connected to an aeration pipe 8. The aeration pipe 8 is vertically installed on the floating plate 1, with its lower end passing through the floating plate 1 and inserted into the water to blow air into the water.

[0007] Preferably, the floating plate 1 has a square mounting window 9 that runs vertically through it, and the mounting plate 10 is mounted on the positioning step 91 set on the edge of the mounting window 9 by screws; the blower 4, the battery 5, the solar charging panel 6, and the small wind turbine 7 are all integrated and mounted on the mounting plate 10, and the aeration pipe 8 is mounted on the mounting plate 10.

[0008] Preferably, the lower end of the aeration pipe 8 is connected to an aeration head 11, the aeration head 11 includes an aeration cylinder 111 with one end open 3 and the other end closed, and aeration blades 112 uniformly connected to the side wall of the aeration cylinder 111; the aeration cylinder 111 is connected to the lower end of the aeration pipe 8; the aeration blades 112 have an internal hollow structure and are connected to the aeration cylinder 111, and aeration holes 113 are provided on the side wall of the aeration blades 112.

[0009] Preferably, the aeration cylinder 111 is rotatably mounted on the support frame 12 fixedly connected to the bottom of the mounting plate 10 via bearings, and the opening 3 end of the aeration cylinder 111 is rotatably connected to the lower opening 3 of the aeration pipe 8 via bearings; the mounting plate 10 is equipped with a drive motor 13 that is pulsatorically connected to the aeration cylinder 111, the drive motor 13 is connected to the storage battery 5, and drives the aeration cylinder 111 and the aeration blades 112 to rotate.

[0010] Preferably, both the drive motor 13 and the aeration cylinder 111 are provided with transmission gears 14, and the two transmission gears 14 are connected by a toothed belt 15 or a chain. The toothed belt 15 or chain passes through the through hole 16 opened on the mounting plate 10.

[0011] Preferably, the mounting plate 10 is provided with handles 17 at both ends to facilitate lifting the mounting plate 10.

[0012] Preferably, a baffle 18 is provided at the top edge of the float 1.

[0013] Preferably, the four corners of the floating plate are provided with connecting ears 20 with connecting holes 21, and multiple ecological purification devices are connected and spliced ​​together to form a larger floating island by bolts through the connecting ears 20.

[0014] The beneficial effects of this utility model are: 1. This utility model integrates surface plant purification technology with underwater aeration technology. Above water, plants in planting pots 2 absorb nutrients such as nitrogen and phosphorus from the water, and microorganisms attached to their roots degrade pollutants. Underwater, air is forcibly injected into the water through blowers 4 and aeration pipes 8 (and aeration heads 11), significantly increasing dissolved oxygen levels. This synergistic effect of "plant absorption + microbial degradation + artificial oxygenation" not only purifies the surface water but also improves the oxygen-deficient environment at the bottom, accelerating the decomposition of organic matter in the sediment. It fundamentally achieves three-dimensional, comprehensive, and efficient purification of the water, solving the problems of traditional floating ecological islands having limited functionality and poor bottom water restoration effects.

[0015] 2. By integrating a solar charging panel 6 and a small wind turbine 7, and storing the generated electricity in a battery 5 to power the blower 4, this invention completely eliminates dependence on mains power. This wind-solar hybrid power generation mode ensures a relatively stable energy supply under various weather conditions, including day and night and sunny and cloudy days, enabling the device to operate long-term, stably, and autonomously in remote waters, scenic lakes, and reservoirs without external power sources. This not only significantly reduces operating costs and energy consumption but also embodies a green and environmentally friendly ecological concept.

[0016] 3. The core components, including the blower 4, battery 5, and energy equipment, are all integrated onto a single mounting plate 10 and secured to the mounting window 9 of the float 1 using detachable screws, forming a standard functional module. This modular design makes the transportation, on-site installation, and subsequent maintenance (such as replacing the battery 5 and overhauling the blower 4) of the device extremely convenient. Maintenance personnel can simply unscrew the screws to lift the entire functional module for maintenance, eliminating the need for complex disassembly of the float and significantly reducing the difficulty and cost of operation and maintenance.

[0017] 4. The aeration head 11 of this utility model has a unique design. The hollow aeration blades 112 connected to the side wall of the aeration cylinder 111 and the aeration holes 113 on their surface can disperse the airflow into a large number of fine bubbles, greatly increasing the gas-liquid contact area and improving oxygen transfer efficiency. More importantly, the transmission system consisting of a drive motor 13, a transmission gear 14, and a belt / chain drives the entire aeration head 11 and aeration blades 112 to rotate slowly in the water. The rotating aeration blades 112 act like an underwater agitator, effectively breaking up water stratification and forming horizontal and vertical water flow circulation, allowing oxygen and purified water to diffuse over a wider area and avoiding purification dead zones. Compared with static aeration, dynamic aeration has a higher oxygen utilization rate and a better energy efficiency ratio. Attached Figure Description

[0023] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0024] like Figure 1-5 As shown, the ecological purification device provided by this utility model mainly includes a floating plate 1, a plant planting unit, a self-powered system, a power module, and a rotary aeration system. This purification device is mainly used in relatively still water areas such as polluted wetlands or ponds near sewage treatment plants.

[0025] The float 1 is made of lightweight, high-strength polyethylene (HDPE) material and can be circular, square, or polygonal in shape. It is filled with foam material to ensure sufficient buoyancy. Multiple planting pots 2 for planting aquatic plants are fixedly connected to the bottom of the float 1. The planting pots 2 are preferably mesh structures to facilitate root extension and full contact with the water. The top of the float 1 has an opening 3 communicating with the interior of the planting pots 2, facilitating the planting of plants into the pots and their growth above the water surface. Optional aquatic plants with strong purifying abilities, such as canna lilies, irises, and water onions, can be planted in the pots.

[0026] The bottom of the floating plate 1 is also connected by a suspension rope to a targeted wet cube 19 located underwater. This targeted wet cube 19 uses the published patent technology "CN202221600583.8 A targeted wet cube 19 for improving the water quality of wetlands or reservoirs". This targeted wet cube 19 effectively solves the water pollution problems in wetland polluted waters and wastewater reservoirs. It not only improves the water quality in wetland waters and wastewater reservoirs, but also uses the adsorption and filtration materials used in wastewater treatment as bio-fertilizer. The non-metallic mineral bio-adsorption and filtration materials that adsorb and filter nutrients such as organic matter, ammonia nitrogen, total nitrogen, and total phosphorus during wastewater treatment are used as the substrate for bio-fertilizer.

[0027] A square mounting window 9 extending vertically through the center of the floating plate 1 is provided. The edges of the mounting window 9 are provided with inwardly protruding positioning steps 91.

[0028] A baffle 18 is provided at the top edge of the float 1. The baffle 18 can prevent excessive water waves from splashing onto the mounting plate 10 when the water sways significantly, thus avoiding interference with the operation of the electrical system.

[0029] The power module and self-powered system are highly integrated onto a single mounting plate 10. Its dimensions match the mounting window 9, and it can be secured to the positioning step 91 with screws, allowing the mounting plate 10 to rest stably on the floating plate 1. For ease of maintenance, handles 17 are fixedly installed at both ends of the mounting plate 10, facilitating the overall disassembly and reassembly of the integrated power structure and self-powered structure for inspection and repair.

[0030] A solar charging panel 6 and a small wind turbine 7 are mounted on the upper surface of the mounting plate 10. The output terminals of the solar charging panel 6 and the small wind turbine 7 are connected to a charge / discharge controller (not shown in the figure) via wires. This controller is then connected to a battery 5 to achieve wind-solar hybrid power generation and intelligent charging management of the battery 5. The output terminal of the battery 5 is electrically connected to a blower 4 via wires to provide it with operating power.

[0031] The rotary aeration system includes an aeration pipe 8 and an aeration head 11. The aeration pipe 8 is preferably a rigid PVC pipe, its top end connected to the air outlet of the blower 4, and it passes vertically downwards through the mounting plate 10. The aeration head 11 is located underwater, and its core component is an aeration cylinder 111. One end of the aeration cylinder 11114 is open (3), and the other end is closed. The open end (3) is rotatably connected to the lower open end (3) of the aeration pipe 8 via a bearing. Simultaneously, the middle part of the aeration cylinder 111 is rotatably supported on a support frame 12 via another bearing. This support frame 12 is fixedly connected to the bottom of the mounting plate 10. Therefore, the aeration cylinder 111 can rotate freely relative to the mounting plate 10 and the aeration pipe 8.

[0032] On the side wall of the aeration cylinder 111, multiple hollow aeration blades 112 are radially and uniformly connected or integrally formed. These aeration blades 112 communicate with the internal cavity of the aeration cylinder 111. On the side wall of each aeration blade 112, a large number of aeration holes 113 are evenly distributed.

[0033] To drive the aeration head 11 to rotate, a drive motor 13 (such as a small DC geared motor) is also mounted on the mounting plate 10. This drive motor 13 is also powered by the battery 5. Transmission gears 14 are fixedly mounted on the output shaft of the drive motor 13 and at corresponding positions on the aeration cylinder 111. The two transmission gears 14 are connected by a toothed belt 15 (or chain). The toothed belt 15 passes through a through hole 16 in the mounting plate 10, thereby transmitting the power of the drive motor 13 to the aeration cylinder 111, causing the entire aeration head 11 and its aeration blades 112 to rotate slowly in the water.

[0034] The floating plate has connecting lugs 20 with connecting holes 21 at its four corners. Multiple ecological purification devices are connected and spliced ​​together using bolts through the connecting lugs 20 to form a larger floating island. By aligning the connecting holes 21 of the connecting lugs 20 of different ecological purification devices together, and securing them with bolts and nuts, multiple ecological purification devices are fixedly connected together to form an ecological floating island of the required size. Alternatively, existing floating islands with only planting pots can be used and spliced ​​with the purification devices of this invention at intervals, thereby controlling the installation density of the power supply system, power module, and rotary aeration system of the entire water area floating island.

[0035] The working process of this utility model is as follows: After the device is deployed into the water body to be restored, the float 1 floats on the water surface. The solar charging panel 6 and the small wind turbine 7 convert natural light and wind energy into electrical energy, which is stored in the battery 5.

[0036] Battery 5 supplies power to blower 4 and drive motor 13; the air generated by blower 4 is delivered to aeration cylinder 111 through aeration pipe 8 and distributed to each hollow aeration blade 112, and finally released into a large number of fine bubbles through aeration holes 113. At the same time, drive motor 13 drives aeration cylinder 111 and aeration blade 112 to rotate continuously through transmission gear 14 and toothed belt 15.

[0037] The rotating aeration blades 112 shear the air bubbles into finer particles, increasing the dissolved oxygen surface area. They also act as underwater flow promoters, agitating the water and creating a circulating flow that spreads the oxygen-rich water over a wider area, particularly increasing dissolved oxygen in the bottom water. Simultaneously, the aquatic plants in the planting pot 2 absorb pollutants such as nitrogen and phosphorus from the water through their roots, and their dense root systems also provide a habitat for microorganisms to degrade these pollutants.

[0038] Thus, through the above-described specific embodiments, this utility model has achieved the synergistic repair function of self-powered energy supply, aquatic plant purification, and underwater dynamic aeration and propulsion.

[0039] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
