Description

Technical Field

[0001] This utility model relates to the field of water purification technology, and more specifically, to a mobile ecological floating wetland purification device. Background Technology

[0002] Water is a fundamental environmental element for the survival of aquatic organisms. Ecological water replenishment ensures sufficient water volume in rivers, lakes, wetlands, and other water bodies, maintaining suitable water levels and depths. However, if the water source for ecological replenishment is polluted, the water quality of the original water body will deteriorate after replenishment. For example, if the replenishment water source contains large amounts of nutrients such as nitrogen and phosphorus, it will lead to eutrophication of the original water body, causing an explosive growth of algae. Even if the water source undergoes some treatment before replenishment, it may still contain some pollutants that are difficult to remove, such as heavy metal ions. These pollutants accumulate in wetland water bodies and have toxic effects on the original aquatic organisms.

[0003] Furthermore, changes in water level and flow after ecological water replenishment may cause pollutants in the sediment to be released back into the water body. During long-term sedimentation, sediment absorbs large amounts of organic matter, heavy metals, and other pollutants. When water levels rise or water flows agitate the sediment, these pollutants can desorb and enter the water body. For example, in some eutrophic wetlands, the flushing action of replenished water can release phosphorus from the sediment, further exacerbating eutrophication.

[0004] To address this, ecological floating wetland purification devices are typically installed in water bodies for water remediation. Their working principle is primarily based on simulating natural wetland ecosystems, achieving water purification through the interaction between plants, microorganisms, and the water. The plant roots in the device not only directly absorb nutrients such as nitrogen and phosphorus from the water for their own growth and metabolism, but also provide a habitat for microorganisms to attach and grow. Microorganisms form biofilms on the root surface, and through their metabolic activities, they decompose organic matter in the water, converting it into carbon dioxide, water, and simple inorganic substances. Simultaneously, some microorganisms can participate in the cycling of elements such as nitrogen and phosphorus, further removing pollutants from the water. Furthermore, the presence of plant roots slows down water flow, promotes the sedimentation of suspended particles, and thus improves water transparency.

[0005] However, traditional floating wetland purification devices are mostly fixed, unable to move flexibly according to the degree of water pollution, resulting in low purification efficiency and difficulty in targeting heavily polluted areas, leading to ineffective resource utilization. Furthermore, existing devices also have shortcomings in adapting to water level changes, precise positioning, and efficient removal of multiple pollutants. For example, fluctuations in water level may affect the purification function, such as preventing plant roots from properly contacting the water or causing the device to be over-submerged, thus reducing purification effectiveness. In addition, in actual operation, traditional devices often lack efficient energy utilization, relying on external power supply, increasing operating costs and environmental impact.

[0006] In conclusion, developing a mobile ecological floating wetland purification device that can move flexibly, adapt to water level changes, be precisely positioned, efficiently purify multiple pollutants, and has a sustainable energy supply is of great practical significance.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0041] In one alternative embodiment, refer to Figures 1-6 The mobile ecological floating wetland purification device provided in this embodiment includes a support frame 10, a lifting device 11 fixed on the support frame 10, a floating platform 20 fixed on the lifting device 11, and a plant planting unit 30, a water purification unit, and a water quality monitoring unit on the floating platform 20. The floating platform 20 includes a fixed frame 21 connected to the lifting device 11, and a plurality of fixed grooves 22 are formed on the fixed frame 21 to accommodate and support the floating bed 27. The length and width of the fixed grooves 22 are adjustable. Specifically, the fixed frame 21 includes a crossbeam 23 and a longitudinal beam 24 forming the periphery. A plurality of crossbars 25 are slidably connected between the two longitudinal beams 24 at intervals, and a plurality of longitudinal bars 26 are slidably connected between the two crossbeams 23 at intervals. The planting trough 28 of the floating bed 27 is equipped with a planting unit, which includes a multi-layer filter structure 31 at the bottom of the planting trough 28, a composite planting substrate 32 on the multi-layer filter structure 31, and aquatic plants 33. The bottom and sides of the planting trough 28 are provided with water permeable holes 29, and a filter screen 30 is fixed at the water permeable hole 29.

[0042] The water purification unit includes an aeration assembly 12 fixed to a fixed frame 21 and a bio-rope 13 fixed to the bottom of a floating bed 27. The aeration assembly 12 is used to introduce air into the water, and the bio-rope 13 is covered with selected and acclimatized microbial communities. The water quality monitoring unit includes various sensors 18 for water quality testing. These sensors 18 include a dissolved oxygen sensor 18, a pH sensor 18, a phosphorus and ammonia nitrogen sensor 18, a heavy metal ion sensor 18, and an organic matter concentration sensor 18.

[0043] The support frame 10 includes a frame body and guardrails fixed to the frame body. The support frame 10 is equipped with a drive device 14 and a positioning unit. The drive device 14 drives the support frame 10 to move; the positioning unit includes a position fixing device 15 and a positioning device 19. The position fixing device 15 is used to fix the movable ecological floating wetland purification device in a fixed water area, and the positioning device 19 is used to determine the geographical location and heading of the floating platform 20. Specifically, the position fixing device 15 is an anchoring system or mooring rope. The anchoring system includes an anchor rope 152, an electric winch 151, and a counterweight 153. The positioning device 19 includes a GPS positioning module and an electronic compass. The drive device 14 includes a thruster and a drive motor installed at the bottom of the floating platform 20.

[0044] The support frame 10 is also equipped with an energy device that supplies power to the lifting device 11, water purification unit, water quality monitoring unit, drive device 14, and positioning unit. Specifically, the energy device includes a power generation device 16 and a battery 17 connected to the power generation device 16. The power generation device 16 can be a solar panel or a wind power generation device 16. The energy device, lifting device 11, water purification unit, water quality monitoring unit, and positioning unit are electrically connected to the controller.

[0045] It is understood that the mobile ecological floating wetland purification device provided in this embodiment mainly consists of a support frame 10, a lifting device 11, a floating platform 20, a plant planting unit 30, a water purification unit, a water quality monitoring unit, a drive device 14, a positioning unit, and an energy device.

[0046] The support frame 10 serves as the basic support structure for the entire device, bearing all other components. For areas susceptible to water flow impact, guardrails or buffer zones can be installed on the support frame 10 to absorb some of the impact energy when the floating bed 27 is struck by external objects, reducing the impact on the main body of the floating bed 27 and protecting the plant roots from direct mechanical damage. The lifting device 11 is fixed to the support frame 10, with the floating platform 20 connected above it. The lifting device 11 can flexibly adjust the height of the floating platform 20 according to changes in water level, ensuring that all functional units operate normally under different water level conditions and maintaining a stable purification effect.

[0047] The floating platform 20 is connected to the lifting device 11. The floating platform 20 includes a fixed frame 21 and floating beds 27. The fixed frame 21 is composed of horizontal beams 23 and vertical beams 24 forming the perimeter. Several horizontal bars 25 are slidably connected between the two vertical beams 24 at intervals, and several vertical bars 26 are slidably connected between the two horizontal beams 23 at intervals, thereby forming multiple fixed slots 22 that accommodate and support the floating beds 27. The length and width of the fixed slots 22 are adjustable. The adjustable length and width of the fixed slots 22 allow the floating platform 20 to adapt to floating beds 27 of different sizes. The layout and number of floating beds 27 can be flexibly adjusted according to actual purification needs, improving space utilization and purification effect. For example, when a larger floating bed 27 is needed to grow large aquatic plants 33, or when small floating beds 27 need to be arranged closely to increase planting density, the size of the fixed slots 22 can be easily adjusted by sliding the horizontal bars 25 and vertical bars 26, improving the compatibility and adaptability of the device to different types of floating beds 27.

[0048] It should be noted that the sliding connection method can be either a slide rail or a slider connection. Slide rails are installed along the length of the crossbeam 23 and longitudinal beam 24, respectively. These slide rails can be T-shaped slide rails, dovetail slide rails, etc. Matching sliders are installed at the ends of the crossbar 25 and longitudinal bar 26. For example, a T-shaped slider can be embedded in a T-shaped slide rail, and a dovetail slider can slide within a dovetail slide rail. Fastening bolts can be installed on the sliders. When the crossbar 25 or longitudinal bar 26 slides to the appropriate position, the bolts are tightened to ensure a tight fit between the slider and the slide rail, thereby fixing the position of the crossbar 25 and longitudinal bar 26 and locking the dimensions of the fixing groove 22.

[0049] The plant cultivation unit 30 is located within the cultivation trough 28 of the floating bed 27. The plant cultivation unit 30 includes a multi-layer filtration structure 31, a composite cultivation substrate 32, and aquatic plants 33. The multi-layer filtration structure 31 at the bottom of the cultivation trough 28 serves to initially purify the water and prevent substrate loss. For example, it consists of a coarse sand layer, an activated carbon layer, and a fine sand layer from bottom to top. The coarse sand layer intercepts larger particles of impurities, the activated carbon layer adsorbs odors, organic matter, and some heavy metal ions in the water, and the fine sand layer further filters fine particles, making the water entering the cultivation trough 28 and coming into contact with the plants cleaner, providing a good aquatic environment for plant growth, and also helping to protect the composite cultivation substrate 32 from being washed away by the water flow. The composite cultivation substrate 32 is composed of vermiculite, peat moss, zeolite, etc., mixed in a certain proportion, providing rich nutrients and a good growth environment for the aquatic plants 33. Vermiculite possesses excellent water retention and aeration properties, peat moss is rich in humus, providing a long-lasting nutrient supply for plants, and zeolite exhibits ion exchange and adsorption capabilities, adjusting the substrate's pH and adsorbing harmful substances in the water. The combination of these three elements provides an ideal medium for the growth of aquatic plants 33. The bottom and sides of the planting trough 28 are equipped with permeable holes 29, each fitted with a filter screen 30. This ensures normal water exchange between the planting trough 28 and the surrounding water, allowing plant roots to fully contact the water and absorb nutrients, while also preventing the loss of the planting substrate. Through its physiological activities, the aquatic plants 33 absorb nutrients such as nitrogen and phosphorus, as well as heavy metal ions, from the water, thus purifying the water.

[0050] The selection of aquatic plants 33 is crucial because different aquatic plants 33 exhibit specific abilities to remove pollutants. For example, water chestnuts have a strong ability to absorb nutrients such as nitrogen and phosphorus, while water celery, in addition to absorbing nitrogen and phosphorus, has a good enrichment effect on some heavy metal ions such as copper and zinc. By planting water chestnuts and water celery alternately in the planting trough 28 of the floating bed 27, they can target different types of pollutants in the same aquatic environment, achieving synergistic removal of nitrogen, phosphorus nutrients, and heavy metal ions, significantly improving water purification efficiency.

[0051] Different aquatic plants have different growth cycles and purification activity periods. Some aquatic plants, such as sweet flag (Acorus calamus), grow vigorously and have strong purification capabilities in spring and autumn; while others, such as water lilies, are more active in summer. By planting sweet flag and water lilies alternately, highly efficient aquatic plants can play a role in different seasons, allowing the purification device to maintain a good water quality purification effect throughout the year and extending the purification time.

[0052] Different aquatic plants 33, with their varying forms, sizes, and growth habits, can be planted at intervals to provide diverse ecological niches for microorganisms and aquatic animals. For example, the tall stems of emergent plants like reeds provide roosting and nesting sites for birds, while their roots offer attachment and hiding places for benthic organisms; the leaves of floating-leaved plants like water chestnuts create shaded areas on the water surface, suitable for the survival of some shade-loving microorganisms. By constructing a complex and stable ecosystem through diverse ecological niches, material cycling and energy flow are promoted, enhancing the ecological stability and self-purification capacity of the purification device. Since emergent and floating-leaved plants have different planting conditions, different models of floating beds 27 can be selected as needed. The size of the fixing trough 22 can then be adjusted by changing the intervals between the horizontal bars 25 and the vertical bars 26, allowing for the placement of floating beds 27 of different specifications at intervals.

[0053] Furthermore, to enhance the landscape value, tall, slender-leaved reeds can be planted alternately with brightly colored aquatic irises, creating a visually appealing effect of varying heights and rich colors. The verdant green of the reeds and the vibrant flowers of the aquatic irises complement each other, making the floating wetland purification device not only a practical water purification function but also a beautiful feature of the water area, thus improving its overall landscape quality. Alternatively, a seasonal landscape can be created, where different aquatic plants exhibit different growth states and landscape characteristics with the changing seasons. This dynamic landscape, resulting from seasonal changes, provides diverse viewing experiences and increases the interest and appeal of the landscape.

[0054] The water purification unit includes an aeration component 12 fixed to a fixed frame 21 and a bio-rope 13 fixed to the bottom of a floating bed 27. The aeration component 12 increases the dissolved oxygen content of the water by introducing air, providing a suitable aerobic environment for microorganisms, promoting the decomposition and metabolism of organic matter, and improving water purification efficiency. The bio-rope 13 is covered with selected and domesticated microbial communities that can grow and reproduce on it. These microorganisms decompose organic matter through metabolic activities, participate in nitrogen and phosphorus cycles, and assist in the removal of heavy metal ions, working in conjunction with the plant cultivation unit 30 to complete the water purification task.

[0055] The water quality monitoring unit is equipped with various sensors 18 for water quality testing, including dissolved oxygen sensor 18, pH sensor 18, phosphorus content sensor 18, ammonia nitrogen sensor 18, heavy metal ion sensor 18, and organic matter concentration sensor 18. These sensors 18 can monitor various key indicators of the water body in real time and feed the data back to the controller so that operators can understand the water quality status in a timely manner and adjust the operating parameters of the device according to the monitoring results to ensure the stability and efficiency of the purification effect.

[0056] The drive unit 14 is installed at the bottom of the floating platform 20, providing power to the entire device and enabling it to move freely in the water. It can flexibly adjust its position according to the distribution of pollution in the water, achieving targeted purification of different polluted areas. For example, the drive unit 14 can consist of a propeller and a drive motor.

[0057] The positioning unit includes a position fixing device 15 and a positioning device 19. The position fixing device 15 is used to fix the movable ecological floating wetland purification device in a specific water area, preventing the device from drifting due to external forces such as water flow and waves, ensuring the stability and continuity of the purification work, and can also adjust the fixed height of the device according to water level changes. Specifically, it can be an anchoring system or a mooring rope system. The anchoring system can include an anchor rope 152, an electric winch 151, and a counterweight 153. The electric winch 151 controls the raising and lowering of the anchor rope 152, and the counterweight 153 increases the stability of the anchoring. The mooring system includes an electric winch 151 and mooring ropes. The positioning device 19 is used to determine the geographical location and heading of the floating platform 20, including a GPS positioning module and an electronic compass, providing accurate data support for the movement of the drive device 14, facilitating accurate control by operators to reach the designated location.

[0058] The energy unit, mounted on the support frame 10, supplies power to the lifting device 11, water purification unit, water quality monitoring unit, drive device 14, and positioning unit. The energy unit can utilize solar panels and connected batteries 17 to charge the device using solar energy, converting it into electricity and storing it to provide power. Alternatively, it can use a wind power generator 16 and connected batteries 17 to power the device. This sustainable energy supply method reduces the device's dependence on external power sources, lowers operating costs, and aligns with environmental protection and energy conservation principles. The energy unit, lifting device 11, water purification unit, water quality monitoring unit, and positioning unit are all electrically connected to a controller, enabling intelligent control of each unit.

[0059] Instructions for Use: First, assemble the support frame 10 and fix the lifting device 11 to the support frame 10. Then, connect the fixed frame 21 of the floating platform 20 to the lifting device 11. On the fixed frame 21, adjust the length and width of the fixed groove 22 by sliding the horizontal bar 25 and the vertical bar 26, and place the floating bed 27 in the fixed groove 22. Lay a multi-layer filter structure 31 at the bottom of the planting trough 28 of the floating bed 27, fill it with composite planting substrate 32, and plant aquatic plants 33. Fix the aeration component 12 to the fixed frame 21, and fix the bio-rope 13 to the bottom of the floating bed 27. Install the thruster and drive motor of the drive device 14 on the support frame 10, and install the positioning unit's position fixing device 15 (such as an anchoring system or mooring rope) and positioning device 19 (GPS positioning module and electronic compass) in the appropriate positions. Finally, install the energy device (solar panel or wind power generation device 16 and corresponding battery 17) on the support frame 10, and electrically connect each unit to the controller. After the device is put into use, the energy unit continuously supplies power to each unit. The water quality monitoring unit monitors various indicators of the water body in real time and transmits the data to the controller. Operators can view the water quality data through the controller and, based on the water quality conditions and the device's location information, control the drive device 14 to adjust the device's position, moving it to a more heavily polluted area for targeted purification. Simultaneously, according to water level changes, the height of the floating platform 20 is adjusted using the lifting device 11, and the fixed height of the movable ecological floating wetland purification device is adjusted using the position fixing device 15. The aeration component 12, based on data from the dissolved oxygen sensor 18, is controlled by the controller to regulate its oxygenation level, providing a suitable growth environment for microorganisms. When it is necessary to fix the device's position, the anchor rope 152 and counterweight 153 are lowered by operating the electric winch 151, securing the device in the designated water area.

[0060] It should be noted that after commissioning, the operating status of each unit should be checked regularly, such as checking the accuracy of sensor 18, the aeration effect of aeration component 12, and the power performance of drive device 14. Accumulated impurities in the floating bed 27 and planting trough 28 should be cleaned, and the nutrient content of the planting substrate should be checked, supplementing or replacing it as necessary. The microbial community on the bio-rope 13 should be monitored; if a decrease in microbial activity is found, corresponding optimization measures can be taken, such as adjusting water quality conditions or adding specific nutrients. The power generation efficiency of the energy device and the stored capacity of battery 17 should be checked regularly to ensure the stability of the energy supply.

[0061] This utility model's mobile ecological floating wetland purification device can be flexibly moved according to the pollution status of different water areas. It can adjust its fixed height to ensure the floating platform 20 floats stably on the water surface when the water level changes, allowing for targeted purification of polluted areas and improving purification efficiency. This effectively solves the problem that traditional fixed devices cannot flexibly handle large areas of heterogeneous polluted water. Simultaneously, the length and width of the fixing groove 22 formed on the fixed frame 21 are adjustable, accommodating floating beds 27 of different specifications to meet diverse plant planting and purification needs, thus enhancing the device's versatility.

[0062] Through the coordinated operation of the plant cultivation unit 30, the water purification unit, and the water quality monitoring unit, the system achieves efficient removal of multiple pollutants. It effectively addresses complex polluted water bodies, overcoming the limitations of existing devices in purifying multiple pollutants.

[0063] The setup of the drive unit 14, positioning unit, and controller enables precise positioning and intelligent control of the device. Operators can adjust the device promptly based on real-time monitoring data and device location information to ensure the stability and efficiency of the purification effect.

[0064] The energy device uses a combination of solar panels or wind power generation device 16 and storage battery 17 to provide sustainable energy for the device, reduce operating costs, conform to the concept of environmental protection and energy conservation, and improve the independence and stability of the device in operation under different environmental conditions.

[0065] This invention effectively solves the problems of traditional ecological floating wetland purification devices through the coordinated work of its various units and devices, and has significant economic and environmental benefits. It has important application value in the field of water environment management.
