[0021] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0022] A multifunctional ecological floating bed structure and a water purification method thereof according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Example

Exemplarily, aquatic plants with nitrogen and phosphorus absorption capabilities may include but are not limited to wild rice stem, reed, cattail, water hyacinth, azolla, water chestnut, water chestnut, hornwort, and ceratophyllum.

[0024] A carrier member 301 having a biofilm for attaching microorganisms; An intelligent irrigation system 401 is used to automatically adjust the amount of water according to plant needs and directly supply water to the roots of plants; Among them, the irrigation system can automatically turn on or off, adjust the water flow intensity and irrigation time of the sprinkler, detect soil moisture changes through a humidity sensor before irrigation, and feed this information back to the automatic control system, thereby regulating the drainage volume of the intelligent irrigation system 401.

[0025] The floating platform 1 is made of a lightweight and high-strength composite material, which contains regenerated cellulose fibers and natural rubber particles, which improves the durability of the platform and enhances its biodegradability; A microbubble generator 9 is used to increase the dissolved oxygen content in the water body and automatically adjust the bubble size and frequency according to the water quality monitoring data through the control unit; When the dissolved oxygen in the water is lower than 5 mg / L, it means that the water is seriously lacking in oxygen and needs to be supplemented with oxygen quickly; reduce the size of the bubbles to make it easier for the bubbles to diffuse and increase the contact area with the water. Increase the frequency of bubbles to quickly increase the dissolved oxygen content in the water. Install a dissolved oxygen sensor, a temperature sensor, a pH sensor, and a conductivity sensor in the component waterproof box 15 to monitor water quality parameters in real time and transmit the monitoring data to the control unit. The control unit analyzes the current water quality conditions according to preset thresholds and rules.

[0026] For example, when the dissolved oxygen is lower than 5 mg / L, the central control unit sends instructions to the microbubble generator 9, and the central control unit sends instructions to reduce the bubble size and increase the bubble frequency.

[0027] The retractable awning 13 is used to adjust the light intensity to meet the growth requirements of different plants. The awning 13 is made of waterproof and light-transmitting material to prevent rainwater accumulation; The component waterproof box 15 is used to install components.

[0028] It should be noted that the floating platform 1 is the core component of the multifunctional ecological floating bed. It is made of a lightweight and high-strength composite material that combines regenerated cellulose fibers and natural rubber particles. Regenerated cellulose fibers provide good flexibility and tensile strength, while natural rubber particles enhance the elasticity and wear resistance of the material. More importantly, the combination of these two materials gives the platform a high biodegradability and reduces the impact on the environment. The structural setting of the floating platform 1 takes into account the durability and stability of long-term exposure to water, ensuring that the floating bed structure can remain in good condition for a long time in various water environments.

[0030] Furthermore, the biofilm carrier 301 is made of polymer material and is in the shape of a plate-like structure with a plurality of holes. These holes not only increase the surface area of ​​the carrier 301, which is conducive to the attachment of microorganisms, but also provide a channel for water flow, ensuring the unimpeded exchange of substances inside and outside the carrier 301. The surface of the carrier 301 is coated with a layer of biofilm, which can effectively adsorb and decompose harmful substances in the water, such as ammonia nitrogen, nitrite, etc., and plays an important role in improving the self-purification ability of the water body. The carrier 301 is installed in a mounting barrel 3, and a plurality of planting grooves 31 are provided on one end face of the mounting barrel 3 for placing plant seeds or seedlings.

[0031] The retractable awning 13 is made of waterproof and light-transmitting material, and the structure is set in a retractable form. The degree of its expansion or folding can be controlled by the first hydraulic cylinder 1001 and the second hydraulic cylinder 12 on both sides. The function of the awning 13 is to provide appropriate shielding for the plants under strong light conditions to prevent excessive light from causing damage to the plants. The material of the awning 13 also has a certain reflectivity, which can effectively reduce the water temperature, especially in the high temperature period in summer, which is particularly important.

[0032] The component waterproof box 15 is used to install and protect the intelligent irrigation system 401, the microbubble generator 9 and other electronic devices. The waterproof box is made of high-strength plastic and has sufficient internal space to accommodate electronic components of various sizes. The structural setting of the waterproof box takes into account the dual needs of heat dissipation and waterproofing, ensuring that the internal equipment can work normally even in harsh water environments.

[0034] It should be noted that the carrier 301 is installed in a mounting barrel 3, and a plurality of planting grooves 31 are provided on one end face of the mounting barrel 3 for placing plant seeds or seedlings; the microbubble generator 9 is fixedly installed on the carrier 301, and it can generate a large number of tiny bubbles to improve the water quality by increasing the dissolved oxygen content in the water body. The working state of the microbubble generator 9 is automatically adjusted by a control unit according to the water quality monitoring data, for example, the size and release frequency of the bubbles can be adjusted as needed to achieve the best oxygenation effect.

[0035] In some embodiments, a nanoporous bent plate 14 is disposed on the floating platform 1 , and the nanoporous bent plate 14 has high adsorption capacity and biocompatibility, and contains photocatalytic components for decomposing organic pollutants in water under light conditions.

[0036] It should be noted that the nanoporous bent plate 14 is installed in a specific area of ​​the floating platform 1, and its surface is covered with nanoscale holes, which have extremely high adsorption capacity and biocompatibility. The nanoporous bent plate 14 also contains photocatalytic components, which can decompose organic pollutants in water under light conditions and further improve water quality. This structural setting is particularly suitable for heavily polluted water restoration projects.

[0037] Among them, nanoporous bent plates have high adsorption capacity and biocompatibility, mainly using material properties and structural design. See the following for details: Nanoporous materials have a very large specific surface area, which means that there are more surfaces per unit volume available for adsorption of pollutants. The larger surface area provides more active sites, thereby enhancing adsorption capacity. The size of nanopores is usually between a few nanometers and tens of nanometers, which makes them effective in capturing and adsorbing small molecules and ionic level pollutants.

[0038] The surface of nanoporous materials usually contains various functional groups (such as hydroxyl, amino, carboxyl, etc.), which can react chemically with pollutants to form stable chemical bonds, thereby improving adsorption efficiency. The charge characteristics of the nanomaterial surface can also affect the adsorption performance. For example, a positively charged surface can attract negatively charged pollutants, and vice versa.

[0039] Nanoporous plates can be made of biologically inert materials (such as silica, alumina, etc.) that do not cause immune responses or cytotoxicity in biological environments.

[0040] The micro-nanostructure of nanoporous materials can simulate the microstructure of natural biological tissues, which helps cell recognition and attachment, thereby improving biocompatibility.

[0041] In some embodiments, it also includes: The IoT water quality monitoring system installed in the component waterproof box 15 can wirelessly transmit data to the cloud server, automatically analyze the water quality status through artificial intelligence algorithms, and has an automatic alarm function.

These sensors can monitor various indicators in the water body in real time, such as pH value, temperature, dissolved oxygen, conductivity, etc., and transmit the data to the cloud server through a wireless network. The cloud server uses an artificial intelligence algorithm to analyze the water quality. Once an abnormality is found, the system will automatically issue an alarm to notify relevant personnel to take measures. In addition, the water quality monitoring data can also be used to guide the work of the intelligent irrigation system 401 and the microbubble generator 9 to achieve more accurate water quality management.

[0044] It should be noted that the breathable membrane and microporous aeration tube at the bottom of the installation barrel 3: a special breathable membrane is set at the bottom of the installation barrel 3. This breathable membrane uses a special polyester material, which can not only ensure the free flow of water and oxygen, but also prevent fine particles from entering the installation barrel 3 to block the roots of plants. A series of microporous aeration tubes are also set below the breathable membrane. These aeration tubes are connected to the microbubble generator 9, which can continuously deliver oxygen to the root area of ​​the plant, promote the respiration of the plant root system, and thus improve the growth efficiency of the plant.

[0045] In some embodiments, wave-breaking barriers 201 are arranged around the floating platform 1, and the wave-breaking barriers 201 are used to mitigate wave impact and protect the stability of the floating bed structure.

[0046] It should be noted that the wave barrier 201 is arranged around the floating platform 1, mainly used to mitigate the impact of waves on the floating bed structure. The structural setting of the wave barrier 201 takes into account the wind and wave resistance and stability. It is usually made of flexible materials, which can absorb and disperse wave energy to a certain extent and protect the floating bed from damage. Under strong wind or high wave conditions, the wave barrier 201 can effectively maintain the stability of the floating bed and ensure the smooth progress of ecological restoration work.

A support spring 8 is fixed to the bottom of the support adjustment member 4. Through the elastic action of the support spring 8, the slight displacement of the planting rack 2 caused by plant growth or external factors can be buffered to maintain the balance of the entire system. The structural setting of the nutrient solution adding groove 41 facilitates the operator to regularly replenish the nutrient solution to ensure that the plants have sufficient nutrient supply.
