[0034] First Embodiment:

[0035] Please refer to Figure 1 and, in conjunction with reference to Figures 2 to 4, this application provides an aquatic environment ecological restoration device, which mainly includes a floating collection box 1, multiple filter boxes 2, a water pumping mechanism, multiple groups of balance mechanisms, an aerobic bacteria supply mechanism, and a cleaning mechanism; among them, the floating collection box 1 is integrally in a circular trough structure with an open top and a hollow interior. The floating collection box 1 can float on the water surface, and it can also be installed with a driving device to move the floating collection box 1 on the water surface through the driving device; multiple filter boxes 2 are respectively rotatably arranged at intervals on the periphery of the floating collection box 1 through rotating shafts, and the distance between adjacent filter boxes 2 can be the same or different. They are mainly used to filter the collected water; at the same time, the top of each filter box 2 is open, and an inclined filter plate 3 is installed in its inner cavity. The filter plate 3 is inclined in the direction gradually approaching the floating collection box 1 and is used to filter the sundries in the water collected in the filter box 2; an outlet 4 is opened at the upper part of the side of the filter box 2 away from the floating collection box 1. The water pumping mechanism is installed in the floating collection box 1 and is used to pump the water outside the floating collection box 1 into each filter box 2 for filtration; specifically, the water pumping mechanism mainly includes a water pump 5; the water pump 5 is installed in the floating collection box 1, and an inlet pipe 6 is connected to the lower inlet of the water pump 5. The inlet pipe 6 is horizontally arranged at the bottom of the floating collection box 1; an outlet pipe 7 is connected to the top outlet of the water pump 5; the outlet pipe 7 is vertically arranged at the central position in the inner cavity of the floating collection box 1, and multiple nozzles corresponding to the filter boxes 2 are installed at the outlet. In addition, the number of groups of the balance mechanism is the same as the number of filter boxes 2, and each group of balance mechanism includes a fixed rod 8 and a counterweight 9; one end of the fixed rod 8 is connected to the side of the filter box 2 away from the outlet 4, and the other end is connected to the counterweight 9; in addition, an iron block 10 is installed at the end of the fixed rod 8 close to the filter box 2, and a magnet 11 that can be separated from or attracted to the iron block 10 is installed on the floating collection box 1. Furthermore, the aerobic bacteria supply mechanism includes multiple compression air bags 12, multiple aeration pipes 13, a culture box 14, multiple hoses 15, and multiple manual regulating valves 16; among them, the compression air bag 12 is connected between the side of the floating collection box 1 and the bottom of the corresponding filter box 2. The compression air bag 12 is respectively connected with an inlet pipe 17 and an aeration pipe 13 for aerating the water. A one-way valve 18 is connected to the inlet pipe 17. The aeration pipe 13 is vertically placed in the water body. When squeezed, the air inside the compression air bag 12 will be discharged outward through the aeration pipe 13. By injecting air into the water, a better living environment is provided for aerobic bacteria; at the same time, the upper end of the culture box 14 is open and is installed in the inner cavity of the floating collection box 1; and one end of each of the multiple hoses 15 is respectively connected to the culture box 14 at intervals along the outer peripheral wall of the culture box 14, and the other end is respectively connected to the corresponding compression air bag 12; the manual regulating valve 16 is installed on the hose 15.The cleaning mechanism is used to clean the filter plate 3. During use, the suspended substances on the water surface are usually relatively small and can easily block the mesh holes of the filter plate 3 or adhere to the surface of the filter plate 3. The cleaning mechanism is designed specifically for this situation. It mainly includes an air duct main pipe 19, multiple air blowing nozzles 20, multiple connecting pipes 21, and multiple solenoid valves 22. Among them, the air duct main pipe 19 is slidably arranged inside the filter tank 2 and is located below the filter plate 3. Moreover, a chute 23 is provided on the inner side wall of the filter tank 2, and a slider 24 is slidably installed in the chute 23. The air duct main pipe 19 is fixedly connected to the slider 24, and the slider 24 is used to drive the air duct main pipe 19 to move in the chute 23. At the same time, the multiple air blowing nozzles 20 are respectively installed on the air duct main pipe 19 at intervals and all face the filter plate 3, and are used to blow air to the bottom surface of the filter plate 3. In addition, the connecting pipe 21 communicates between the air duct main pipe 19 and the compression air bag 12, and is used to transmit the air in the compression air bag 12 to the air duct main pipe 19. The solenoid valve 22 is arranged between the connecting pipe 21 and the compression air bag 12, and is used to control the flow rate of the gas when it passes through. In addition, a solar panel 25 is also installed on the floating collection box 1.

[0036] It should be noted that the compression air bag 12 can adopt a V-shaped air bag.

[0037] It should be noted that the balance mechanism, the rotating shaft, and the filter tank 2 form a simple seesaw structure. When there is very little water in the filter tank 2, the balance mechanism presses on the filter tank 2 to maintain balance. When the water volume in the filter tank 2 increases to a certain amount, this balance will be broken. The fixed rod 8 is fixed with an iron block 10, and the floating collection box 1 is fixed with a magnet 11. Therefore, in the balanced state, the iron block 10 and the magnet 11 attract each other, and under the gravity of the counterweight 9, the filter tank 2 is pressed. When the water volume in the filter tank 2 gradually increases to a certain critical value, the iron block 10 and the magnet 11 will separate, causing the filter tank 2 to rotate and pour out the water. As the water is poured out, the weight of the filter tank 2 decreases, and under the action of the counterweight 9, the filter tank 2 will rotate in the reverse direction to its original position.

[0038] In addition, since the inner wall of the filter tank 2 is provided with a chute 23, the air duct main pipe 19 is fixed with a slider 24, and the slider 24 is slidably connected to the chute 23. This sliding connection method makes the chute 23 and the filter plate 3 have different heights on one side in the balanced state. When the balance is broken, the filter plate 3 rotates following the filter tank 2, thereby causing the height on both sides of the chute 23 to change, resulting in the slider 24 automatically sliding in the chute 23. In this way, the position of the air blowing nozzle 20 can be automatically adjusted, enabling a larger area of the filter plate 3 to be blown.

[0039] Furthermore, since the compression airbag 12 is connected to an air inlet pipe 17, the air inlet pipe 17 is connected to a one-way valve 18, the incubator 14 is fixedly connected to the floating collection box 1, the upper end of the incubator 14 is open and the outlet is connected to the compression airbag 12 through a hose 15, and a manual regulating valve 16 is provided on the hose 15; therefore, the cultured aerobic bacteria are added into the incubator 14, the manual regulating valve 16 is opened to adjust the dropping speed, so that the aerobic bacteria are added into the compression airbag 12. When the compression airbag 12 expands, the outside air enters the compression airbag 12 unidirectionally through the one-way valve 18 for replenishment.

[0040] Meanwhile, the water outlet 4 of the water pump 5 is connected to a water outlet pipe 7. The water outlet pipe 7 is vertically arranged at the central position of the floating collection box 1. The water inlet pipe 6 is arranged on the lower side surface of the water outlet pipe 7 and is equidistantly distributed around the side surface of the blowing pipe. In this way, the suspended matters around the floating collection box 1 can be sucked and filtered.

[0041] In addition, a control component is designed on the device. The control component mainly includes a microprocessor and an image collector. The microprocessor and the image collector can both adopt the structures in the prior art, and their specific structures and working principles will not be elaborated here; among them, the microprocessor is electrically connected to the solenoid valve 22 and the image collector respectively. The microprocessor and the image collector are both installed in the single-chip microcomputer; and the single-chip microcomputer is fixedly connected to the floating collection box 1. The image collector is used to photograph the surface of the inclined filter plate 3 and obtain an image; the microprocessor processes the obtained image to determine the clogging condition of the inclined filter plate 3; the microprocessor can also control the opening size of the solenoid valve 22 according to the clogging condition. For example, the more serious the clogging is, the larger the solenoid valve 22 opens. In this way, when the compression airbag 12 is compressed, more gas will be blown out to the filter plate 3 through the blowing nozzle 20, and when the clogging is not serious, the solenoid valve 22 can be opened a little smaller. In this way, more air will be blown into the water and no waste will be caused.

[0042] The device not only filters and collects the suspended substances on the water surface through the water pumping mechanism and the inclined filter plate 3, but also cleverly uses the weight of the pumped water to generate power to drive the compression airbag 12 to work. When the compression airbag 12 works, it can not only inject air and aerobic bacteria into the water through the aeration pipe 13 to purify the water quality, but also, under the coordinated action of the microprocessor, make the multiple blowing nozzles in the cleaning mechanism automatically clean the surface of the filter plate 3, so as to ensure the normal operation of the whole device.

[0043] The working principle of the device is:

[0044] First, add the cultured aerobic bacteria into the incubator 14, and open the manual regulating valve 16 to allow the aerobic bacteria to drip into the compression airbag 12. Place the floating collection box 1 on the water surface, and drive the water pump 5 to work by generating electricity through the solar panel 25. When the water pump 5 works, it pumps water from the surrounding of the floating collection box 1 through the water inlet pipe 6 and sprays it upward through the water outlet pipe 7. The water sprayed out from the water outlet pipe 7 falls into the filter box 2, and the suspended debris filtered out slides into the floating collection box 1 through the surface of the filter plate 3 and is collected.

[0045] The water in the filter box 2 gradually increases. When a certain amount of water is reached in the filter box 2, the balance of the balance mechanism is broken, causing the filter box 2 to rotate downward around the rotating shaft. When the filter box 2 rotates downward, the water inside it is slowly poured out through the water outlet 4. And when the filter box 2 rotates, it will squeeze the compression airbag 12. When the compression airbag 12 is compressed, it injects air into the aeration pipe 13, so that the air is sprayed out from the lower end of the aeration pipe 13 to a deeper position of the water body, producing an aeration effect. Also, when the compression airbag 12 is compressed, the aerobic bacteria inside it will be discharged to the bottom of the water through the aeration pipe 13, so as to use the aerobic bacteria to decompose some harmful substances in the water. At the same time, when the balance of the balance mechanism is broken, an image collector such as a camera takes a picture of the inclined filter plate 3 and obtains the captured image. The microprocessor performs binary processing on the obtained image. The filter plate 3 in the image is represented by white, and the rest is represented by black. Calculate the ratio N of the area of the black region to the area of the white region. Determine the blockage condition of the inclined filter plate 3 according to the size of the ratio N. Subsequently, use the microprocessor in the existing technology to control the opening size of the solenoid valve 22 according to the blockage condition. When the compression airbag 12 is compressed, part of the air sequentially passes through the connecting pipe 21, the air path main pipe 19, and the air blowing nozzle 20 and is sprayed onto the lower surface of the filter plate 3. Among them, the more serious the blockage condition is, the greater the amount of air sprayed out through the air blowing nozzle 20. In addition, since the air path main pipe 19 is slidably connected to the filter box 2, when the filter box 2 rotates, the air path main pipe 19 will also slide in the length direction of the filter box 2, so that the air blowing nozzle 20 moves under the filter plate 3 and automatically adjusts the blowing position, making the cleaning effect on the mesh holes of the filter plate 3 better. When a certain amount of water in the filter box 2 is poured out, under the balance action of the balance mechanism, the filter box 2 rotates in the reverse direction and returns to its original position.

[0046] In summary, in the water environment ecological restoration device of the present application, the solar panel 25 generates electricity to drive the water pump 5 to work. When the water pump 5 works, it pumps water from the surrounding of the floating collection box 1 through the water inlet pipe 6 and sprays it upward through the water outlet pipe 7. The water sprayed out by the water outlet pipe 7 falls into the filter box 2, and the filtered suspended debris slides into the floating collection box 1 through the surface of the inclined filter plate 3 to be collected, while realizing the purification operation of the water body. At the same time, when the compression airbag 12 compresses, it can inject air into the aeration pipe 13, so that the air is sprayed out from the lower end of the aeration pipe 13 to a deeper position of the water body, producing an aeration effect. And when the compression airbag 12 compresses, the aerobic bacteria inside it will be discharged to the bottom of the water through the aeration pipe 13, so as to use the aerobic bacteria to decompose some harmful substances in the water. Therefore, this device greatly improves the working efficiency of water filtration and purification, saves time and effort, greatly reduces the working intensity of operators, and has a good purification effect.

[0047] Second Embodiment:

[0048] In this embodiment, a water environment ecological restoration method is provided. This method uses the water environment ecological restoration device in the first embodiment to restore the water body, and mainly includes the following steps:

[0049] S1. First, add the cultured aerobic bacteria into the culture box 14, open the manual regulating valve 16 to make the aerobic bacteria drip into the compression airbag 12; place the floating collection box 1 on the water surface, and use the solar panel 25 to generate electricity to drive the water pump 5 to work. When the water pump 5 works, it pumps water from the surrounding of the floating collection box 1 through the water inlet pipe 6 and sprays it upward through the water outlet pipe 7. The water sprayed out by the water outlet pipe 7 falls into the filter box 2, and the filtered suspended debris slides into the floating collection box 1 through the surface of the filter plate 3 to be collected;

[0050] S2. The water in the filtration tank 2 gradually increases. When the water level in the filtration tank 2 reaches a certain amount, the balance of the balance mechanism is broken, causing the filtration tank 2 to rotate downward around the rotating shaft. When the filtration tank 2 rotates downward, the water inside it is slowly poured out through the water outlet 4. And when the filtration tank 2 rotates, it will squeeze the compression airbag 12. When the compression airbag 12 is compressed, it injects air into the aeration pipe 13, so that the air is ejected from the lower end of the aeration pipe 13 to a deeper position in the water body, producing an aeration effect. Also, when the compression airbag 12 is compressed, the aerobic bacteria inside it will be discharged to the bottom of the water through the aeration pipe 13, so as to utilize the aerobic bacteria to decompose some harmful substances in the water. At the same time, when the balance of the balance mechanism is broken, an image collector such as a camera takes a picture of the inclined filter plate 3 and obtains the captured image. The microprocessor performs binarization processing on the obtained image. The filter plate 3 in the image is represented by white, and the rest is represented by black. Calculate the ratio N of the area of the black region to the area of the white region. Determine the clogging condition of the inclined filter plate 3 according to the size of the ratio N. Subsequently, the microprocessor in the prior art is used to control the opening size of the solenoid valve 22 according to the clogging condition. When the compression airbag 12 is compressed, part of the air is sequentially ejected to the lower surface of the filter plate 3 through the connecting pipe 21, the air path main pipe 19, and the air blowing nozzle 20. Among them, the more serious the clogging condition is, the greater the amount of air ejected through the air blowing nozzle 20. In addition, since the air path main pipe 19 is slidably connected to the filtration tank 2, when the filtration tank 2 rotates, the air path main pipe 19 will also slide in the length direction of the filtration tank 2, so that the air blowing nozzle 20 moves below the filter plate 3 and automatically adjusts the air blowing position, making the cleaning effect on the mesh holes of the filter plate 3 better. When a certain amount of water in the filtration tank 2 is poured out, under the balance action of the balance mechanism, the filtration tank 2 rotates in the reverse direction and returns to its original position.

[0051] It should be noted that in step S2, the ratio N is divided into three levels, namely N1, N2, and N3. Among them, 0% ≤ N1 < 30%, 30% ≤ N2 < 60%, 60% ≤ N1 ≤ 100%. The microprocessor is electrically connected to the solenoid valve 22 and the camera respectively, and the sizes of its control for the solenoid valve 22 to open are closed, open half, and fully open respectively.

[0052] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
