Description

Technical Field

[0001] This invention relates to the technical field of garden construction equipment, and in particular to a device for inhibiting the growth of Spirogyra. Background Technology

[0002] Spirogyra is a common eukaryotic organism belonging to the family Dipterophyceae, and is a general term for green algae in the genus Spirogyra. Spirogyra is a filamentous organism composed of uniseriate, long, tubular cells, and thrives in slow-moving freshwater. In agricultural and urban landscape water bodies, excessive growth of Spirogyra is frequently observed, severely impacting the aquatic ecological balance and reducing the productivity and ornamental value of aquatic plants. Therefore, in recent years, Spirogyra has shown a significant increasing trend in aquatic ecosystem research, becoming an important research direction in water environment restoration. The management of Spirogyra has long been a challenge in the maintenance and management of water landscapes. This paper discusses the potential problems that may arise during the application of various prevention and control measures.

[0003] Currently, physical control methods are commonly used to address the excessive proliferation of Spirogyra. Common methods include manual removal, black soil treatment, and artificial aeration. While manual removal is convenient and safe, and does not cause secondary pollution to the water, it requires significant manpower and resources and cannot fundamentally solve the problem of excessive Spirogyra growth. Black soil treatment uses a type of charcoal-black soil that purifies water; a layer of black soil is spread at the bottom of the water to effectively block direct sunlight from reaching the bottom, thus inhibiting Spirogyra growth. In practical engineering projects, this method has been found to be environmentally friendly and highly feasible. However, spreading black soil at the bottom reduces the water's light transmittance, affecting the growth of submerged plants and reducing the aesthetic appeal of the water body. Furthermore, water quality monitoring and ecological restoration are often independent processes, lacking coordination, leading to high treatment costs and unsatisfactory results. Summary of the Invention

[0004] This application provides a device for inhibiting the growth of Spirogyra, which can achieve physical interception and ecological inhibition of Spirogyra, while intelligently monitoring water quality, so as to improve the level of intelligence and ecology in water environment management.

[0005] This application provides a device for inhibiting the growth of Spirogyra, which adopts the following technical solution: A device for inhibiting the growth of Spirogyra includes: an ecological floating island floating on the water surface, the ecological floating island including a floating body on the periphery and a top supporting platform; a planting area is provided in the floating body, the planting area is planted with aquatic plants that inhibit the growth of Spirogyra through competition for nutrients and light; the supporting platform is provided with a Spirogyra collection component, the Spirogyra collection component is used to intercept and guide Spirogyra to a preset collection area; the supporting platform is provided with a Spirogyra recycling and treatment component, the Spirogyra recycling and treatment component includes, in sequence along the Spirogyra guide path, a lifting mechanism, an incineration conversion module and a plant fertilization system, the incineration conversion module converts Spirogyra into nutrient solution, the nutrient solution is returned to the planting area of ​​the ecological floating island through the plant fertilization system.

The floating component has an installation groove, the skeleton tube is embedded in the installation groove and sealed and fixed by a plug in the installation groove, and a planting plate is provided on the inner ring of the skeleton tube.

[0007] Preferably, the planting plate and the skeleton tube are movably connected by a chain, which is composed of multiple rigid chain links hinged together, and the chain is made of hot-dip galvanized steel.

[0008] Preferably, the planting board includes root-penetrating holes and a fully enclosed lateral enclosure, wherein at least two partitions are provided inside the lateral enclosure to form independent planting troughs, and the planting troughs are used to plant different types of aquatic plants in different areas.

[0009] Preferably, the Spirogyra collection component includes a symmetrically arranged outer frame and an internal corrosion-resistant mesh. The bottom of the outer frame contacts the bottom of the water body and the top protrudes above the water surface. The corrosion-resistant mesh is made of polyethylene and has a pore size of less than 2 mm.

[0010] Preferably, the outer frame is rotatably connected to the mounting plate at the bottom of the support platform via a hinge, and a cylinder is provided at the top of the support platform. The output end of the cylinder is hinged to the middle of the outer frame, and the cylinder drives the outer frame to rotate around the hinge.

[0011] Preferably, the limiting plate at the bottom of the bearing platform and the mounting plate form a closed protective area, and an impeller is provided in the protective area, with the height of the limiting plate exceeding the upper surface of the impeller.

[0012] Preferably, the impeller is driven to rotate in both directions by a waterproof motor, and the distance between the limiting plate and the mounting plate in the protective area is greater than the width of the impeller.

[0013] Preferably, the water hyacinth recycling and treatment component includes, in sequence, a funnel-shaped guide hood, a spiral elevator, a high-temperature resistant conveying pipe, and an incineration chamber along the water hyacinth's flow path. The outlet of the incineration chamber is connected to a fermentation tank. The fermentation tank separates nutrient solution from impurities through a filter component inside the fermentation tank. The nutrient solution is then returned to the planting area via a spray head at the top of the skeleton pipe of the ecological floating island.

[0014] Preferably, the high-temperature resistant conveying pipe is equipped with a bidirectional jet pipe, which is used to push the incinerated organic matter to the fermentation tank.

[0015] In summary, this application has the following beneficial effects: 1. This invention, through its integrated design of "physical interception + ecological competition + intelligent monitoring," offers advantages over existing technologies in controlling Spirogyra outbreaks, including ecological safety, environmental friendliness, speed and efficiency, and high aesthetic appeal. It effectively solves the problems of multi-stage separation and low efficiency in water environment management, demonstrating significant practical value and promising prospects. It is an ecologically safe and aesthetically pleasing method for controlling Spirogyra outbreaks.

[0016] 2. To address the problems of scattered planting and low competition efficiency in traditional aquatic plant cultivation, this invention innovatively designs a modular ecological floating island system. The core of this system lies in the combined structure of a U-shaped framework tube and detachable planting panels. The framework tube not only provides buoyancy support, but the planting panels within it are flexibly connected by chains, allowing for adaptive angle adjustment when the water surface fluctuates. The planting panels contain independent planting troughs and root-penetrating holes, allowing for the planting of allelopathic aquatic plants such as water lilies and calamus in designated areas. This design achieves three main functions: first, modular planting ensures plant density, enhancing competitive pressure on Spirogyra; second, the root-penetrating holes allow roots to fully contact the water, maximizing nutrient absorption efficiency; and third, the flexible connection structure ensures the stability of the device in windy and wave-prone environments, making the ecological suppression effect continuous and reliable.

[0017] 3. To address the problems of traditional fixed and non-adjustable interception nets and their susceptibility to clogging, this invention develops a dynamic interception system based on cylinder drive. This system consists of a symmetrically arranged outer frame, a corrosion-resistant net, hinges, and cylinders. An image sensor monitors the accumulation of spirulina in real time. When the spirulina density exceeds a threshold, the control system drives the cylinders to extend and retract, allowing the outer frame to precisely swing around the hinge axis within a 0-45° range. This innovation achieves three optimizations: first, the adjustable angle design adapts to waters with different flow rates, reducing resistance by decreasing the angle during high-speed flows; second, the periodic swinging of the net generates a self-cleaning effect, preventing pore clogging; and third, the interception range can be dynamically expanded, increasing the coverage area during floods. The entire system ensures long-term reliable operation through corrosion-resistant materials and a waterproof motor.

[0018] 4. To address the high cost and secondary pollution associated with the post-harvest treatment of Spirogyra, this invention constructs a closed-loop treatment chain of "collection-conversion-reuse." The core system includes modules such as a flow guide hood, a spiral elevator, a bidirectional jet incineration device, and a fermentation chamber. Its innovation lies in: First, the bidirectional jet assembly within the high-temperature resistant pipe enables automatic material transport; forward jets deliver Spirogyra into the incineration chamber, while reverse jets blow the ash into the fermentation chamber. Second, controllable incineration at 400-500℃ ensures thorough decomposition of organic matter while avoiding high-temperature energy waste. Finally, multi-stage filtration within the fermentation chamber allows the separated nutrient solution to be precisely re-irrigated into the plants via a top-spray system on the framework pipe. This system transforms Spirogyra into the nutrient solution needed for plant growth, solving the waste disposal problem, reducing the cost of purchased fertilizers, and achieving true resource recycling.

[0019] 5. To address the lack of data support in traditional treatment methods, this invention integrates an intelligent network of water quality sensors, image sensors, and mechanical actuators. The system operates on three levels: the perception layer collects water quality data in real time through pH sensors and dissolved oxygen probes, while image sensors monitor the distribution of Spirogyra; the analysis layer processes the data using algorithms to establish a Spirogyra growth prediction model; and the execution layer automatically adjusts parameters such as cylinder angle and impeller speed based on the analysis results. The system's breakthroughs are: firstly, it achieves closed-loop control for Spirogyra treatment for the first time, directly converting monitoring data into execution commands; secondly, it continuously optimizes the control strategy through machine learning, improving treatment accuracy; and thirdly, it supports remote monitoring, significantly reducing the frequency of manual inspections. This intelligent design enables the device to autonomously adapt to the changing needs of different aquatic environments. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0022] This invention discloses a device for inhibiting the growth of Spirogyra, such as... Figure 1 As shown, the system includes a support platform 1, with a floating body 2 surrounding the support platform 1. The floating body 2 is made of high-density polyethylene. The ecological floating island, composed of the high-density polyethylene floating body 2 and the support platform 1, floats on the water surface. The interior of the floating body 2 is equipped with a planting area for planting a combination of plants to control the growth of Spirogyra. A planting board 3 is set up in the planting area of ​​the floating body 2, and the planting board 3 is planted with a combination of plants to control the growth of Spirogyra. The plant combination, which is planted on the ecological floating island, includes aquatic plants such as water lilies and calamus. By competing with Spirogyra for resources such as nutrients and light, the growth of Spirogyra is inhibited from an ecological perspective.

[0023] Furthermore, the aquatic plants include emergent plants, floating plants, and submerged plants. A three-layer plant cover: emergent + floating + submerged plants are combined to comprehensively suppress Spirogyra from three aspects: light, nutrients, and space. Native and suitable varieties are selected: priority is given to common local varieties (such as lotus, calamus, and Vallisneria natans), which are highly adaptable, easy to maintain, and reduce ecological risks.

[0024] Specifically, 1. Emergent plants occupy the area above the water surface, blocking strong sunlight; Lotus: Its large and dense leaves block sunlight from reaching the water surface, reducing the photosynthesis of Spirogyra.

[0025] Sweet flag: It has a well-developed root system that absorbs nutrients such as nitrogen and phosphorus from the water and competes for Spirogyra growth resources.

[0026] Pickerelweed: It grows rapidly, has a strong clumping ability, quickly occupies water surface space, and inhibits the spread of Spirogyra.

[0027] 2. Floating plants float on the water surface, blocking light and absorbing nutrients.

[0028] Water lilies: Their leaves float and cover the water surface, blocking underwater light while absorbing nutrients from the water.

[0029] Water hyacinth (Eichhornia crassipes): It grows quickly and floats on the water surface to form a dense covering layer, blocking sunlight from reaching the Spirogyra (be careful to control the extent to avoid overgrowth).

[0030] Water lily: Its leaves are small and dense, with strong buoyancy, making it suitable for small water features and gently suppressing water hyacinth.

[0031] 3. Submerged plants grow underwater, competing for nutrients in the substrate and improving water quality.

[0032] Vallisneria: Its roots penetrate the bottom mud, absorbing nutrients from the substrate, while its leaves block some sunlight underwater.

[0033] Hydrilla verticillata: It grows rapidly, with dense underwater branches and leaves, competing for light and nutrients from Spirogyra, and can also improve dissolved oxygen in the water.

[0034] Elodea: It is highly adaptable, tolerant of low temperatures, and can grow year-round, continuously competing for Spirogyra growth resources.

[0035] like Figure 2 As shown, specifically, the float 2 includes a "U"-shaped skeleton tube 201 assembled from various parts, a float component 202 made of high-density polyethylene wrapped around the outside of the skeleton tube 201, and an installation component 203 for connecting the skeleton tube 201 and the support platform 1.

[0036] like Figure 2 As shown, the floating component 202 has a columnar structure, and an installation groove 204 is provided on its upper surface. The skeleton tube 201 is installed in the installation groove 204 of the floating component 202, and the floating component 202 is sealed and fixed to the skeleton tube 201 through the plug 205 in the opening of the installation groove 204. The concave cross-section forms a multi-directional force support structure through geometric angles, which significantly improves the longitudinal bending stiffness and lateral torsional performance. The opening design of the installation groove 204 is precisely fitted with the installation component 203 to form a mechanical self-locking mechanism to prevent component displacement; thereby effectively dispersing the impact force of wind and waves, reducing the risk of local stress concentration, and extending the overall service life.

[0037] like Figure 2As shown, the planting plate 3 is further located within the inner circle of the U-shaped skeleton tube 201, and its shape matches that of the skeleton tube 201. The skeleton tube 201 and the planting plate 3 are movably connected by a chain 4. The chain 4 is composed of multiple rigid chain links hinged together, forming a flexible linkage structure that allows the planting plate 3 to swing slightly in the horizontal and vertical directions. This automatically compensates for the deformation of the skeleton tube 201 caused by water surface fluctuations, such as the tilting of the float 2 caused by waves, and avoids structural stress concentration caused by rigid connections. The chain 4 is usually made of hot-dip galvanized steel, and the surface treatment enhances its resistance to water corrosion.

[0038] like Figure 2 As shown, the planting board 3 has root-penetrating holes 5 inside, and a lateral enclosure 6 is provided on the outer perimeter of the upper surface of the planting board 3. The lateral enclosure 6 is a fully enclosed structure, and several partitions 7 are provided inside the lateral enclosure 6. The partitions 7 divide the lateral enclosure 6 on the planting board 3 into several planting troughs. Different combinations of plants that control the growth of Spirogyra are planted in different planting troughs. The roots of the plant combinations pass through the root-penetrating holes 5 of the planting board 3 and extend into the water, playing a role in purifying the water quality. First, the design of the zoned planting troughs effectively avoids the problem of excessive reproduction of a single plant. If plants grow in a disorderly manner, they may crowd out water space, just like Spirogyra, and even cause new ecological imbalances. Independent planting troughs can strictly limit the growth range of each plant and also facilitate the individual observation of the growth status of different plants later. For example, it can determine whether a certain type of plant is growing slowly due to environmental unsuitability and reduce maintenance difficulty. Second, the root-penetrating hole 5 brings a dual effect of "root purification + nutrient competition", forming an ecological closed loop to inhibit Spirogyra. Plant roots absorb nutrients, weakening the supply of Spirogyra, and purifying water quality destroys the growth environment of Spirogyra. The combination of the two inhibits the growth of Spirogyra from the "source", which is more effective in the long term than simple physical harvesting.

[0039] like Figure 1 As shown, an integrated intelligent detection component 8 is fixedly installed on the carrier platform 1. The integrated intelligent detection component 8 includes a water quality sensor 801 for monitoring pH and dissolved oxygen, an image sensor 802 for monitoring the growth status of Spirogyra and plants, and a data processing module, thereby collecting and transmitting water environment data in real time.

[0040] Specifically, the integrated intelligent detection component 8 uses "real-time monitoring - data analysis - information transmission" as its core logic. Among them, the water quality sensor 801 serves as the basic monitoring unit, specifically collecting key water quality indicators that affect the growth and ecological balance of Spirogyra, including pH value (Spirogyra thrives in a neutral to slightly alkaline environment with a pH of 6.5-8.5; abnormal pH values ​​directly inhibit its photosynthesis) and dissolved oxygen (excessive dissolved oxygen content promotes aerobic respiration and reproduction of Spirogyra, while insufficient dissolved oxygen alters the aquatic microbial community, indirectly affecting Spirogyra growth), ensuring accurate capture of subtle changes in the aquatic environment. Secondly, the image sensor 802 captures panoramic and close-up images of the water area at regular intervals (e.g., every 30 minutes).

[0041] The system focuses on monitoring two core objects: first, the coverage area and growth density of Spirogyra (e.g., whether there are patches of floating vegetation); and second, the leaf condition of the plant combinations on the ecological floating island (e.g., whether they are yellowing and withering) and the root development (e.g., whether there are signs of rot). This visual monitoring makes up for the inability of a single water quality indicator to intuitively reflect the dynamics of biological growth. At the same time, the data processing module, as the "core brain" of the component, will process the data from the two types of sensors synchronously.

[0042] The numerical data from water quality sensor 801 is compared with preset ecological safety thresholds (such as pH 6.5-8.5 and dissolved oxygen 5-9 mg / L) to automatically determine whether the water quality is within the range that is "beneficial to plant growth and inhibits Spirogyra". The image data from image sensor 802 is analyzed using image recognition algorithms to determine the growth trend of Spirogyra (such as whether the coverage area has increased by more than 10% in the past 24 hours) and the health of the plants. In addition, all processed data is sent to the back-end management system in real time via a wireless transmission module to form a traceable data ledger, allowing managers to obtain first-hand information remotely without going to the site.

[0043] like Figure 1 As shown, a water sponge collection component 9 is installed on one side of the carrying platform 1 and in the water in front of the ecological floating island to physically intercept water sponges and prevent them from spreading over a wide area.

[0044] like Figure 1 As shown, specifically, the water sponge collection component 9 includes two outer frames 901 symmetrically arranged on the central axis of the support platform 1. The outer frames 901 are equipped with a corrosion-resistant mesh 902. The corrosion-resistant mesh 902 is used to physically intercept the water sponge and prevent it from spreading over a large area.

[0045] First, to physically block the spread of Spirogyra, the Spirogyra collection component 9 adopts a "symmetrical layout + mesh interception" design logic. The outer frame 901 serves as a supporting skeleton and is symmetrically installed at the central axis of the carrying platform 1. This layout ensures that the component covers the main water area in front of the carrying platform 1, preventing Spirogyra from bypassing the interception from one side due to layout deviation. Second, a high-density corrosion-resistant mesh 902 is fixedly installed inside the outer frame 901. The pore size of the mesh has been determined through repeated testing—the pore size is controlled between 0.5-1mm. This effectively blocks the passage of Spirogyra filaments without excessively obstructing the normal flow of water, preventing stagnant water areas around the device due to water accumulation, which could lead to problems such as odor and secondary algae growth. At the same time, considering that the device needs to be immersed in water for a long time, the outer frame 901 is made of 304 stainless steel, which has strong rust resistance; the corrosion-resistant mesh 902 is made of polyethylene, which is resistant to aging and water corrosion.

[0046] In addition, the height of the outer frame 901 will be adjusted according to the water depth of the target water area. In shallow water areas with a depth of 0.5-1m, the frame height is set to 0.8m to ensure that the bottom can contact the bottom of the water and the top is 0.3m above the water surface. In deep water areas with a depth of 1-2m, the frame height is set to 1.5m to prevent the frame from being too short and causing the water to bypass underwater, thus ensuring the interception effect in different water depth scenarios.

[0047] First, physical interception directly cuts off the spread chain of Spirogyra—the spread of Spirogyra mainly relies on water flow to carry the filamentous structures. If not intercepted in time, it can spread to the entire water area within 1-2 days. This component can confine Spirogyra to a small area in front of the device, requiring only concentrated treatment of that area afterward. Compared to "comprehensive dredging" after Spirogyra has spread, this reduces workload by more than 70%. Second, the use of corrosion-resistant materials significantly reduces maintenance costs—traditional interception nets made of ordinary iron wire will rust and break down within 1-2 months, requiring frequent replacement. In contrast, the stainless steel frame and polyethylene net of this component can be used for a long time, requiring only monthly cleaning of the net surface. The use of water-soluble Spirogyra reduces the number of on-site operations required by maintenance personnel. Simultaneously, the "interception without obstruction" design protects the aquatic ecosystem. If the mesh openings are too small, obstructing water flow will alter the flow field of the water body, affecting the activities of aquatic organisms such as fish. A reasonable mesh design ensures normal water circulation, avoiding additional disturbance to the aquatic ecosystem. Furthermore, the adaptability of the components allows for application in various scenarios—whether it's urban landscape ponds, agricultural irrigation canals, or near-shore areas of small lakes. Only the frame height needs to be adjusted for use; no separate design for each scenario is required, enhancing the device's versatility and promotional value, and reducing the investment in governance for different scenarios.

[0048] like Figure 1As shown, two mounting plates 10 are symmetrically arranged at the bottom of the support platform 1. The mounting plates 10 are rotatably connected to one side of the outer frame 901 via hinges 903. A cylinder 904 is rotatably mounted on the upper surface of the support platform 1. The output end of the cylinder 904 is hinged to the middle of the outer frame 901. When the cylinder 904 extends or retracts, it drives the frame to swing around the hinge 903 at 0-45°, ensuring even force distribution and preventing deformation. At the same time, the system remotely controls the cylinder 904 according to the density of the water hyacinth. When the density is high, the angle is increased to increase the interception area, and when cleaning, the angle is decreased to remove the net surface from the water. First, the angle can be flexibly adjusted to adapt to different water flow and water hyacinth distribution. When the water flow is fast, the angle is decreased to prevent the net from deforming, and when the flow is slow, the angle is increased to expand the range. Second, the net surface can be cleaned without disassembly. At the same time, the anti-corrosion and waterproof design ensures the long-term stability of the components and avoids corrosion-induced functional failure. In addition, remote control eliminates the need for manual on-site operation, making it suitable for large areas or sensitive water bodies, improving treatment efficiency and safety.

[0049] like Figure 3 As shown, the bottom of the support platform 1 is provided with two limiting plates 11, which are located outside the mounting plate 10, forming a protective area between the limiting plates 11 and the mounting plate 10. An impeller 12 is installed within this protective area at the bottom of the support platform 1. Firstly, the limiting plates 11 and the mounting plate 10 enclose the protective area, with a height 10cm higher than the impeller 12, preventing the impeller 12 from being collided with or entangled by water droplets or stones. Secondly, the impeller 12 is driven by a waterproof motor, generating thrust by rotating it forward and backward to adjust the direction of the device. Simultaneously, the impeller 12 moves in coordination with the collection assembly, oriented according to the data from the image sensor 802 to the area with dense water droplets. Furthermore, a rubber buffer strip is attached to the inner side of the limiting plates 11 to further block debris and protect the impeller 12.

[0050] Firstly, the protected area reduces impeller 12 entanglement failures by 90%, lowering replacement and maintenance costs and ensuring continuous device movement. Secondly, directional movement enables precise collection of water hyacinth without manual dragging, making it suitable for water areas exceeding 1000㎡. Simultaneously, automated movement requires only one person for remote control, avoiding the risks of manual operation in deep water areas. Furthermore, adjustable speed adapts to different water areas, increasing speed in calm areas and decreasing speed in turbulent areas for stable movement, enhancing the device's adaptability.

[0051] like Figure 3 and Figure 4As shown, a water-soaked area is further formed between the two mounting plates 10. Under the collection guidance of the water-soaked collection component 9, the water-soaked material flows to the water-soaked recycling and treatment component 13 within the water-soaked collection area. Specifically, the water-soaked recycling and treatment component 13 includes, in sequence along the water-soaked flow path, a guide hood 1301, a hoist 1302 with its outlet penetrating the support platform 1, and a high-temperature resistant pipe 1303 located at the output port of the hoist 1302. One end of the high-temperature resistant pipe 1303 is provided with an incineration chamber 1304, and a bidirectional air jet component 1305 is provided inside the high-temperature resistant pipe 1303 and located at the output port of the hoist 1302. Through the air jet component 1305, the water at the output port of the hoist 1302 is... The water-loving plants are guided to the incineration chamber 1304 for incineration. After incineration, organic fertilizer is produced. The organic fertilizer is blown into the fermentation box 1306 at the other end of the high-temperature resistant pipe 1303 by the jet component 1305. The fermentation box 1306 contains fermentation liquid, and impurities and nutrient solution are filtered out by the internal filter component of the fermentation box 1306. The impurities are discharged through the slag discharge port at the bottom of the fermentation box 1306. The output end of the fermentation box 1306 is connected to the skeleton pipe 201 through the output pipe 1307. The nutrient solution passes through the output pipe 1307, the skeleton pipe 201 and several spray heads 14 set at the top of the skeleton pipe 201 to fertilize different combinations of plants that control the growth of water-loving plants.

[0052] First, this component is based on the core principle of "closed-loop process" and has built a complete chain of "water spirulina collection-transmission-conversion-refill".

[0053] In the first step, the guide shroud 1301 uses a funnel-shaped structure to precisely guide the water foam in the collection area into the elevator 1302. Its smooth polyethylene inner wall can prevent water foam from adhering and clogging, ensuring smooth feeding.

[0054] The second step involves the elevator 1302 employing a spiral conveying structure. The spiral blades are driven by a motor to rotate, lifting the water hyacinth from underwater (depth 0.5-2m) to the high-temperature resistant pipe 1303 inside the carrying platform 1. The high-temperature resistant pipe 1303 is made of stainless steel and can withstand temperatures above 600℃, thus solving the problem of transferring water hyacinth "from underwater to above water".

[0055] In the third step, the bidirectional jet assembly 1305 inside the high-temperature resistant tube 1303 plays a guiding role; when the water filament enters the tube, the jet assembly 1305 blows air (0.2MPa) towards the incineration chamber 1304, pushing the water filament to the incineration chamber 1304 at one end of the tube. The incineration chamber 1304 converts the water filament into organic fertilizer through electric heating (temperature controlled at 400-500℃) (the water filament is rich in cellulose, and the ash remaining after incineration contains nutrients such as potassium and phosphorus).

[0056] The fourth step involves the jetting component 1305 blowing air in the opposite direction after incineration, directing the fertilizer towards the fermentation chamber 1306 at the other end of the tube. The pre-mixed fermentation liquid (containing Bacillus subtilis and yeast) in the fermentation chamber 1306 can ferment the fertilizer (temperature controlled at 25-30℃), breaking down large organic molecules into nutrients such as amino acids and small peptides that can be absorbed by plants.

[0057] In the fifth step, the filter components in the fermentation tank 1306 separate the impurities (such as unburned residue) and nutrient solution after fermentation through a 100-mesh filter. The impurities are discharged from the bottom slag outlet, while the nutrient solution is transported to the skeleton pipe 201 through the output pipe 1307.

[0058] The sixth step involves several atomizing spray heads 14 (spaced 30cm apart) at the top of the skeleton tube 201 spraying the nutrient solution evenly onto the plant combination in the planting trough, thus realizing the resource cycle of "spiral - fertilizer - plant".

[0059] The Spirogyra recycling and treatment component 13 realizes the "resource utilization" of Spirogyra, completely changing the traditional extensive treatment mode of "salvaging and discarding". In traditional treatment, if the salvaged Spirogyra is discarded at will, it will easily rot and smell bad on the bank, polluting the soil and groundwater. However, this component transforms Spirogyra into a highly nutritious plant nutrient solution through incineration and fermentation, which not only eliminates pollution but also generates recyclable resources. Secondly, the nutrient solution re-irrigates the plant combination with precise nutrients, which greatly improves the growth status of the plants.

[0060] After absorbing the nutrient solution, the plants have greener leaves and more developed root systems. Their ability to compete with Spirogyra for light and nutrients increases by more than 30%, forming a positive cycle of "Spirogyra treatment → plant nourishment → enhanced algae suppression". This makes the ecological inhibition effect more lasting and eliminates the need for frequent replenishment of new plants. At the same time, resource recycling significantly reduces the cost of treatment.

[0061] On the one hand, nutrient solution can completely replace purchased fertilizer, saving 500-800 yuan per mu of water area per year; on the other hand, Spirogyra does not need to be entrusted to a third party for treatment, reducing waste disposal costs, and is especially suitable for long-term management projects (such as landscape water body maintenance for more than 3 years), reducing the pressure of continuous investment; in addition, the whole process has no secondary pollution.

[0062] The small amount of exhaust gas generated during the incineration process can be filtered through the activated carbon filter at the end of the pipe to remove harmful gases; impurities can be landfilled as ordinary solid waste after being discharged from the slag outlet, without polluting the environment; the nutrient solution refill has no additional emissions, ensuring that the entire treatment process meets the requirements of ecological and environmental protection, avoiding new burdens on the environment while treating Spirogyra, and improving the ecological safety and sustainability of the device.

[0063] Working principle: First, the ecological floating island floats on the water surface via the floating body 2 supporting the platform 1. Aquatic plants are planted in the planting area formed by the skeleton pipe 201 and the planting board 3. The plant roots penetrate deep into the water through the root holes 5 to absorb nutrients such as nitrogen and phosphorus. At the same time, the leaves block sunlight, weakening the photosynthetic capacity of Spirogyra from the source, forming the first barrier of ecological inhibition.

[0064] Then, the spirulina in the water flow is intercepted by the symmetrically arranged outer frame 901 and corrosion-resistant mesh 902. The mesh pores are less than 2mm, which can effectively block the diffusion of spirulina filaments. When the image sensor 802 detects spirulina accumulation, the cylinder 904 drives the outer frame 901 to swing around the hinge 903 by 0-45°, expanding the interception area or tilting the mesh for easy cleaning, realizing the automated adaptation of physical interception.

[0065] Subsequently, the intercepted Spirogyra, propelled by the water flow driven by the impeller 12, converges at the inlet of the guide shroud 1301. The spiral elevator 1302 transports the Spirogyra from underwater to the high-temperature resistant pipe 1303, where the jet assembly 1305 blows it into the incineration chamber 1304 at a pressure of 0.2 MPa. After incineration at 400-500℃, the organic matter is transformed into ash rich in potassium and phosphorus, which is then blown back into the fermentation tank 1306 by the jet to mix with the bacterial solution for composting, generating a nutrient solution.

[0066] Next, the nutrient solution is filtered to separate impurities and then evenly sprayed into the planting trough through the atomizing spray head 14 at the top of the skeleton tube 201. After absorbing the nutrient solution, the plants grow rapidly, further encroaching on the living space of Spirogyra, forming a positive feedback loop of "inhibition enhancement - Spirogyra reduction - nutrient supply".

[0067] Meanwhile, the integrated intelligent detection component 8 continuously monitors the water's pH, dissolved oxygen, and Spirogyra coverage. If the data is abnormal (e.g., dissolved oxygen is below 5 mg / L), the system automatically adjusts the impeller speed 12 to enhance water flow, or prompts the addition of specific plants (e.g., Vallisneria natans) to ensure the continuity of ecological inhibition.

[0068] Finally, all mechanical actions and data are transmitted to the backend via wireless module, allowing managers to remotely control parameters such as incineration temperature and spray frequency, achieving precision in the treatment process and low labor costs.

[0069] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
