Description

Technical Field

[0001] This utility model relates to the field of ecological restoration technology, specifically to an intelligent ecological floating island device. Background Technology

[0002] Ecological floating island technology is a simple, green, and economical water environment ecological management and restoration technology that can effectively remove chemical oxygen demand (COD), nitrogen, phosphorus, and other nutrients from target water bodies. It uses aquatic plants as the main body, employs soilless cultivation principles, and uses polymer materials as a carrier and substrate, leveraging interspecies symbiosis to reduce the pollution load on water bodies. It not only significantly improves water transparency but also inhibits algal growth to a certain extent. Therefore, it can effectively solve the problems of foul odor and eutrophication in water bodies.

[0003] Ecological floating islands are typically composed of several floating panels assembled to achieve the required area and geometric shape. Selected and acclimatized aquatic or terrestrial plants are then planted at appropriate locations on the panels, allowing the plants to grow in an environment similar to hydroponics. Currently, most common ecological floating islands in China are fixed, meaning they are anchored in a specific location within the water body, often with pre-installed aeration pipes underneath. However, these fixed floating islands have several drawbacks: firstly, operation and maintenance are inconvenient, leading to high operating costs; secondly, the island recovery rate is low; and thirdly, the cost of laying aeration pipes is high, and laying pipes is difficult in deeper water environments.

[0004] Therefore, mobile ecological floating islands have begun to appear in China. For example, one type of ecological floating island, with announcement number CN217808943U, uses solar panels to generate electricity to power a fan, and removes pollutants from the water through microorganisms attached to carbon fiber grass and nano-aeration pipes. However, the aeration devices of these ecological floating islands are prone to prolonged operation, which significantly reduces their lifespan and increases maintenance costs.

[0005] Based on this, an ecological floating island needs to be proposed, which can intelligently control the start and stop of aeration according to the water conditions. The electricity consumed comes from clean energy sources such as solar and wind power, and it can effectively remove pollutants in the water. Utility Model Content

[0006] This invention addresses the problems of unsustainable energy and high cost of laying aeration pipes in ecological floating islands by providing a mobile intelligent ecological floating island device. It achieves intelligent aeration through real-time monitoring of the oxidation-reduction potential (ORP) of the water, ensuring sustainable energy, good treatment effect, and low operation and maintenance cost.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A smart ecological floating island device includes a floating island base component, a solar energy system component, a smart control component, a recall component, and a bioremediation component;

[0009] The floating island base assembly includes a floating plate and a base plate mounted on the floating plate;

[0010] The solar system components and intelligent control components are mounted on the base plate. The solar panel is fixedly placed at an angle to the base plate by a solar bracket, and the intelligent control components are fixed below the solar panel. The intelligent control components include a waterproof box and an internally installed solar controller, battery, ORP detection device, aeration pump, relay, microcontroller and signal receiving board with electrical connections.

[0011] The solar controller is used to connect and control the solar panels, and the battery is used to store the electrical energy generated by the solar panels and provide power to other components.

[0012] The ORP detection device is equipped with an ORP electrode probe for real-time monitoring of the ORP value in the water and transmits the data to the microcontroller in real time. When the ORP of the water is lower than the set value, the microcontroller outputs a high level to the relay, the coil closes and the aeration pump circuit is connected, and the aeration pump aerates the water through the aeration head. When the ORP of the water is higher than the set value, aeration stops.

[0013] The signal receiving board is connected to control the recall component, which is a waterproof motor symmetrically distributed on the edge of the floating plate;

[0014] The bioremediation component includes floating plants and bio-fiber ropes; the floating plants are placed in a hollow flowerpot, and the bio-fiber ropes are suspended from the bottom of the hollow flowerpot.

[0015] This invention uses an ORP monitoring device to monitor water quality online and a single-chip microcomputer to intelligently control the start and stop of the aeration pump, thereby regulating the dissolved oxygen concentration in the water in a timely manner. It removes pollutants such as nitrogen, phosphorus, and COD from the water through the synergistic action of plants, microorganisms, and aeration. A recall component allows for remote wireless recall to the shore when maintenance or repairs are needed on the floating island, resulting in high purification efficiency and low maintenance costs. This invention also incorporates a solar energy storage system installed on the floating plate to provide power for the entire floating island, promoting energy conservation and environmental protection.

[0016] The intelligent control component also includes necessary electrical components such as a DC junction box and a voltage regulator module.

[0017] The solar panel is placed at an angle of 25-50 degrees to the substrate to improve the utilization rate of solar energy.

[0018] The floating plants mentioned include one or more of the following: Myriophyllum spicatum, Canna indica, Typha orientalis, Iris tectorum, Iris siberiensis, Lythrum salicaria, Cyperus alternifolius, Thalia dealbata, Pickerelweed, and Nymphaea. Selection must be based on the specific water area being used. Floating plants not originally present in the water area must not be introduced to avoid biological invasion and disruption of the aquatic ecosystem.

[0019] The intelligent control component includes an ORP detection device, an aeration pump, and a battery, all housed on one side of the waterproof box, while other components are located on the other side. Preferably, a honeycomb panel is fixed inside the waterproof box, and the devices within the box are secured to the honeycomb panel with self-tapping screws. Sufficient space is maintained between each device to prevent heat buildup and potential hazards.

[0020] The top of the waterproof box is equipped with a waterproof and breathable valve, which enables the circulation and exchange of air inside the box and can also reduce the temperature inside the waterproof box to a certain extent, ensuring the normal operation of the equipment inside the box.

[0021] The waterproof box has waterproof connectors on both sides. One waterproof connector has two holes, which are used to lead out the ORP electrode probe and the aeration pipe, respectively. The other waterproof connector is used to lead out the cable connecting the solar panel and the recall assembly.

[0022] The aeration pipe is divided into two or more branches by a branch pipe component and is symmetrically arranged at the bottom of the float plate. A check valve is provided between the aeration pipe and the aeration head to prevent water from flowing back into the aeration pump.

[0023] The bottom of the waterproof box is provided with a hanging ear that can be directly fixed to the base plate.

[0024] The solar panel is fixed to the base plate by a bracket, and waterproof rubber gaskets are provided at the connection points; the waterproof motor is connected and fixed to the floating plate by a "U"-shaped bracket.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] (1) In this invention, a solar energy system is used as the power source for the entire intelligent floating island. The oxidation-reduction potential of the water is monitored in real time by an ORP detection device, and the data is transmitted to a microcontroller. When the microcontroller determines that the actual oxidation-reduction potential is lower than the set value, it outputs a high level to the relay, the coil closes, and the aeration pump circuit is connected, aerating the water through the aeration head. When the oxidation-reduction potential of the water is higher than the set value, aeration stops.

[0027] (2) When the floating island needs maintenance, it can be remotely recalled via a recall component. Pollutants in the water are degraded and removed through the roots of floating plants and microorganisms on the biofilm. Compared to the commonly used single-purification method of ecological floating islands in China, this solution adopts a "plant-microorganism-aeration" synergistic purification method, and intelligently controls the dissolved oxygen level in the water to promote the growth and reproduction of microorganisms on the biofilm, further improving the purification efficiency of the floating island.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0035] Example 1

[0036] like Figures 1-5As shown, an intelligent ecological floating island device includes a floating island base component, a solar energy system component, an intelligent control component, a recall component, and a bioremediation component;

[0037] The floating island base assembly includes a floating plate 6 and a base plate 4 mounted on the floating plate; the solar energy system assembly and the intelligent control assembly are mounted on the base plate 4. The solar panel 1 is fixed to the base plate 4 at a 33° angle via a solar panel bracket 2, and waterproof rubber gaskets are provided at the connection points between the solar panel bracket 2 and the base plate 4; the intelligent control assembly is fixed below the solar panel 1; the intelligent control assembly includes a waterproof box 3 and an internally installed solar controller 17, a battery 16, an ORP detection device 23, an aeration pump 24, a relay 21, a microcontroller 19, a DC junction box 20, a DC-DC voltage regulator module 22, and a signal receiving board 18; the bottom of the waterproof box 3 is provided with a hanging lug for direct fixation to the base plate 4;

[0038] The solar controller 17 is used to connect and control the solar panel 1, and the battery 16 is used to store the electrical energy generated by the solar panel and provide power to other components. The ORP detection device 23 is equipped with an ORP electrode probe 9 for real-time monitoring of the ORP value in the water and transmits the data to the microcontroller 19 in real time. When the water ORP is lower than the set value of 50mV, the microcontroller 19 outputs a high level to the relay 21, the coil closes and the aeration pump circuit is connected, and the aeration pump 24 aerates the water through the aeration head 12. When the water ORP is higher than the set value, aeration stops.

[0039] Inside the waterproof box 3, there is a honeycomb panel. The equipment inside the box is fixed to the honeycomb panel with self-tapping screws. There is a certain gap between each piece of equipment to prevent the heat generated by the equipment from accumulating and causing danger.

[0040] The signal receiving board 18 is connected to the control recall component, which consists of waterproof motors 7 symmetrically distributed along the edge of the floating plate 6. The waterproof motors are connected and fixed to the floating plate 6 via a "U"-shaped bracket. The bioremediation component includes floating plants 5 and bio-fiber ropes 10. The floating plants 5 are placed in a hollow flowerpot 8, and the bio-fiber ropes 10 are suspended from the bottom of the hollow flowerpot. The floating plants are canna lilies.

[0041] The intelligent control assembly includes an ORP detection device, an aeration pump, and a battery, all housed on one side of a waterproof box, while other equipment is located on the other side. The waterproof box has waterproof connectors on both sides. The left waterproof connector 14 has two holes for leading out the ORP electrode probe 10 and the aeration pipe 11, respectively; the right waterproof connector 15 is used to lead out the cable connecting the solar panel and the recall assembly.

[0042] A waterproof vent valve 13 is installed on the top of the waterproof box 3. When the temperature inside the waterproof box 3 rises, hot air can flow out from inside the box through the waterproof vent valve 13, and cold air can flow in from the outside through the waterproof vent valve 13. This not only achieves air circulation and exchange inside the box, but also reduces the internal temperature of the waterproof box 3 to a certain extent, ensuring the normal operation of the equipment inside. The two devices that generate the most heat inside the waterproof box 3 are the battery 16 and the aeration pump 24. Therefore, the waterproof vent valve 13 is installed above these two devices to facilitate heat dissipation and reduce the internal temperature of the box.

[0043] The aeration pipe 11 is divided into two or more branches by the branch pipe component and is symmetrically arranged at the bottom of the floating plate. A check valve is provided between the aeration pipe 11 and the aeration head 12.

[0044] To ensure that the structure of the floating plate 6 is not damaged, a strong adhesive is used to connect the base plate 4 and the floating plate 6 instead of the traditional bolt and nut connection.

[0045] Working Principle: On sunny days or when there is sufficient sunlight, the solar panels receive sunlight to generate electricity, which charges the battery via wires. The battery then provides power for the entire floating island. The ORP (Oxidation-Reduction Potential) monitoring device monitors the water's oxidation-reduction potential in real time and transmits the obtained ORP to the microcontroller. When the microcontroller determines that the actual ORP is lower than the set value, it outputs a high level to the relay, closing the coil and activating the aeration pump circuit. The pump then aerates the water through the aeration head. When the feedback ORP is higher than the set value, aeration stops, and this cycle repeats. When the floating island requires maintenance, it can be remotely recalled using a recall component. The floating island utilizes the synergistic effect of the roots of floating plants, microorganisms on the biofilm packing, and aeration to degrade and remove nitrogen, phosphorus, COD, and other pollutants from the water.

[0046] In a certain river restoration area, 480 square meters of ecological floating islands were constructed, with each island measuring 1 square meter, and placed over the restored river channel. Water samples from upstream of the restoration area were used as initial samples, and water samples from downstream were used as test samples. COD, ammonia nitrogen, and total phosphorus in the water were used as evaluation indicators. Seven days after the intelligent ecological floating islands were put into use, the COD removal rate in the tested water samples was 70%, the ammonia nitrogen removal rate was 38%, and the total phosphorus removal rate was 32%. After 14 days of use, the COD removal rate was 85%, the ammonia nitrogen removal rate was 61%, and the total phosphorus removal rate was 55%. In summary, the water restoration effect was good, and the intelligent floating islands operated stably.
