Description

TECHNICAL FIELD

[0001] The present application relates to the field of energy saving and environmental protection sewage treatment, and particularly relates to a river outlet self-detection in-situ sewage purification method. BACKGROUND

[0002] With the continuous acceleration of urbanization process in China, the construction scale of urban drainage system is also increasing year by year. The urban drainage system is an important part of the urban lifeline, which bears the functions of collecting, transporting and discharging urban domestic sewage, industrial wastewater and rainwater runoff, and is an important part of the ecological civilization strategy that is worth paying attention to in the process of promoting.

[0003] With the continuous acceleration of urbanization process in China, the construction scale of urban drainage system is also increasing year by year. The end of the urban drainage system is the river inlet sewage outlet located along the river. The effluent pollution of these river inlet sewage outlets is the total root cause of urban river water pollution and eutrophication and even black odor. This is because the combined system drainage pipeline has accumulated a large amount of sludge due to small flow during "sunny days"; the rainwater pipeline of the separated system also has the problem of sludge accumulation due to the problem of sewage pipeline mixing. When "rainy days" come, the sludge accumulated in the pipeline of the combined system drainage pipeline or the rainwater pipeline of the separated system is washed into the river inlet sewage outlet and enters the surface water, causing eutrophication and even black odor. Therefore, the surface water receiving the river inlet sewage outlet usually presents the phenomenon of "clear on sunny days and black on rainy days", so it is urgent to implement timely and efficient purification for the rainy day pollution of the river inlet sewage outlet.

[0004] In addition, China also pays more and more attention to the treatment of new pollutants in rivers, and most of the new pollutants in rivers also come from the rainy day discharge of the river inlet sewage outlet. New pollutants have serious harm to the health of the food chain of surface water and the balance of aquatic ecosystems.

[0005] In summary, the market urgently needs a new device that can solve the effluent pollution problem of the river inlet sewage outlet at the end of the urban drainage system, the construction of the food chain of the surface water receiving the river inlet sewage outlet, and the restoration of the water ecological system. SUMMARY

[0006] The technical problem to be solved by the present application is to overcome the defects of the existing purification equipment of the river inlet sewage outlet, which cannot conveniently adjust the depth or horizontal position in the water body, is not sufficient for water purification, and cannot adapt to more abundant water areas. The present application provides a river outlet self-detection in-situ sewage purification method.

[0007] The present application solves the above technical problems by the following technical scheme:

[0008] The application discloses a river channel outlet self-detecting in-situ sewage purification method, and relates to the technical field of sewage purification.

[0009] The middle control device receives the pre-judgment outlet position information of the main function device, and the pre-judgment outlet position information corresponds to the water area of the river-inlet outlet to be treated;

[0010] The middle control device determines the horizontal moving position and the vertical height position of the main function device according to the pre-judgment outlet position information, and sends the horizontal moving position and the vertical height position to the submersible floating device and the propelling device;

[0011] The submersible floating device obtains the vertical height position and controls the main function device to float up or dive down according to the vertical height position;

[0012] The propelling device obtains the horizontal moving position and controls the main function device to horizontally move according to the horizontal moving position.

[0013] In the scheme, the middle control device receives the pre-judgment outlet position information, determines the horizontal and vertical moving information, and controls the submersible floating device and the propelling device, so that the purification device can conveniently adjust the depth or the horizontal position in water, and the water body purification is more sufficient, so as to adapt to more abundant water area conditions.

[0014] Preferably, the submersible floating device comprises a gas bag,

[0015] The submersible floating device controls the main function device to float up or dive down according to the vertical height position, and the method comprises the following steps:

[0016] The middle control device controls the volume change of the gas bag, so that the main function device floats up or dives down.

[0017] In the scheme, the gas bag is used as the submersible floating device, and the floating up and diving down of the main function device can be realized by controlling the volume of the gas bag. When the gas bag is inflated, the buoyancy of the gas bag can be used to support the main function device to float up, and after the gas bag is deflated, the main function device can freely dive down under the action of gravity. The control mode is simpler.

[0018] Preferably, the gas bag is arranged in a horizontal and circumferential direction of the main function device, and the sewage purification method comprises the following steps:

[0019] The middle control device receives the vertical inclination information of the main function device;

[0020] The middle control device determines correction information according to the vertical inclination information, and controls the gas bags on the same side of the inclination direction to increase the corresponding volumes according to the correction information.

[0021] In the present scheme, by arranging multiple air bags in the horizontal circumferential direction and controlling the volume of the air bags in the direction of increasing inclination, the air bags can not only realize the aforementioned up-down diving function, but also realize the inclination correction function, fully utilizing the structural characteristics of the air bag, and the inclination correction is more convenient.

[0022] Preferably, the propulsion device includes a propeller, and the propulsion device controls the horizontal movement of the main functional device according to the horizontal movement position, including:

[0023] The central control device controls the start of the propeller to push the main functional device to move horizontally;

[0024] The central control device controls the closing of the propeller to gradually stop the horizontal movement of the main functional device.

[0025] In the present scheme, the propeller is used as the propulsion device, and the horizontal movement of the main functional device is realized by controlling the opening and closing of the propeller, which is simpler in control mode, and the propeller can work in water environment and be adjusted horizontally more quickly.

[0026] Preferably, a plurality of propellers are arranged in the horizontal circumferential direction of the main functional device, and the central control device controls the start of the propellers to push the main functional device to move horizontally, including:

[0027] The central control device controls the start of part of the propellers and controls the propulsion rate of the started part of the propellers to make the main functional device move horizontally at a constant speed or variable speed, along a straight line or a curve.

[0028] In the present scheme, by arranging multiple propellers in the horizontal circumferential direction and setting the adjustable propulsion rate of the propellers, the horizontal movement trajectory of the main functional device can be optimized, and the path to the preset position is shorter and the time consumption is shorter.

[0029] Preferably, the main functional device includes a plurality of water quality monitoring probes distributed around the periphery, which can monitor the surrounding water pollution degree and transmit water quality information to the central control device.

[0030] The main functional device further includes a plurality of flow rate monitoring probes distributed around the periphery, which can monitor the surrounding water flow direction and flow rate and transmit flow rate information to the central control device.

[0031] The central control device can comprehensively analyze the water quality information and flow rate information through a machine learning algorithm, predict the position of the pollution discharge outlet in the river, and drive the main functional device to run to the vicinity of the river discharge outlet.

[0032] Preferably, the river discharge outlet self-detection in-situ pollution removal method further comprises:

[0033] The main functional device includes several water quality monitoring probes distributed around it, which can monitor the degree of water pollution in the surrounding water and transmit the water quality information to the central control device.

[0034] The main functional device also includes several flow velocity monitoring probes distributed around it, which can monitor the flow direction and velocity of the surrounding water flow and transmit the flow velocity information to the central control device.

[0035] The central control device can comprehensively analyze the water quality and flow velocity information through machine learning algorithms, predict the location of pollution outlets in the river, and drive the main functional device to operate near the river outlet.

[0036] Preferably, the central control device can adjust the purification mode according to the water quality information:

[0037] When the water quality information shows that the pollution level of the surrounding water body is not less than the first preset value (COD≥50mg / L), the central control device will adjust the purification mode to "emergency water purification mode" and control the treatment agent sprayed by the main functional device to be hydrogen peroxide, chlorine dioxide solution or ozone to disinfect and purify the surrounding water body; at the same time, the wavelength of the lamp irradiation light of the central control device will be adjusted to the ultraviolet band of 100-400nm to further disinfect the nearby water body and generate active free radicals under the action of ultraviolet light.

[0038] In this solution, under emergency water purification mode, the central control device can adjust the irradiation wavelength of the light to the ultraviolet band. At the same time, it can output various oxidants such as ozone, hydrogen peroxide or chlorine dioxide. Under the excitation of ultraviolet light, these oxidants generate a large number of active free radicals such as hydroxyl radicals. Then, relying on the strong oxidizing properties of the active free radicals, they can efficiently degrade and oxidize various organic or reducing inorganic substances in the water, and quickly convert them into harmless inorganic substances such as carbon dioxide and water, thus achieving the goal of emergency water purification.

[0039] When the water quality information shows that the pollution level of the surrounding water body is less than the first preset value (COD < 50 mg / L), the central control device adjusts the purification mode to "ecological construction mode" and controls the treatment agent sprayed by the main functional device to be probiotic liquid or algae liquid, so as to spread and reproduce bacteria or algae in the nearby water body; at the same time, the light wavelength of the lamp tube is adjusted to the visible light band of 400-760nm to assist the growth of bacterial liquid or algae liquid, and to improve the aquatic ecology by utilizing the growth characteristics of bacteria and algae.

[0040] In this solution, under the ecological construction mode, the central control device can perform ecological construction functions on the water body, further improving its purification effect. In this mode, bacterial or algal solutions are cultivated in the water body, and the growth characteristics of the bacterial or algal solutions can be used to decompose harmful substances in the water, effectively avoiding the accumulation of solid organic matter, new pollutants, and harmful substances. In particular, it has a good treatment effect on new pollutants such as persistent organic pollutants, antibiotics, and endocrine disruptors, thereby improving water quality. By setting up nano-aeration discs, the gas required for the growth of the bacterial or algal solutions is provided, accelerating the growth process of the bacterial or algal solutions and further improving working efficiency.

[0041] Preferably, the purification device includes a nano-aeration disc, and the purification method includes:

[0042] The central control device receives the water quality information and sends an air supply command to the nano-aeration disc of the main functional device: the greater the degree of water pollution, the greater the air supply; conversely, the air supply is appropriately reduced.

[0043] The nano-aeration disc acquires and outputs nano-bubbles according to the air supply command.

[0044] In this solution, a nano-aeration disc is set up and controlled by a central control device to output nano-bubbles to the purification unit in ecological construction mode, so as to provide the gas required for the growth of bacterial or algal liquid, accelerate the growth process of bacterial or algal liquid, and further improve work efficiency.

[0045] Preferably, the main functional device includes a purification unit, which has multiple through holes, and is equipped with an axial flow pump and a water outlet. The purification method includes:

[0046] The central control device starts the axial flow pump to pump water, which flows into the purification unit through the through hole and out through the outlet.

[0047] In this design, the water flow direction is controlled by an axial flow pump, guiding the water within the purification unit to enter through multiple through-holes and exit through the outlet after purification. This flow direction results in a larger inlet area, and the uniform flow effect of the porous cylinder wall makes the water flow pattern inside the purification unit more uniform, thereby increasing the maximum hydraulic load that the purification equipment can withstand.

[0048] Preferably, the purification equipment includes a solar photovoltaic panel whose surface can be opened and closed, and the purification method further includes the following steps:

[0049] The central control device receives weather information, which corresponds to the water area of ​​the discharge outlet to be treated.

[0050] The central control device sends the first weather information or the second weather information to the solar photovoltaic panel according to the weather conditions;

[0051] The solar photovoltaic panel acquires and opens its surface based on the first weather information to generate solar power using the panel surface, while controlling the rotation of the panel surface so that the panel surface can always face the light source;

[0052] The solar photovoltaic panel acquires and closes its surface based on the second weather information.

[0053] In this solution, solar photovoltaic panels are used to generate electricity using natural energy, which saves more energy. The solar photovoltaic panels can be opened and closed according to the weather conditions under the control of the central control device. When there is plenty of sunshine, the panels can be rotated to face the sun to fully receive solar energy. When there is not enough sunshine, the panels can be retracted to provide working space for other facilities.

[0054] The positive and progressive effects of this invention are that the purification device can be conveniently adjusted in depth or horizontal position in the water body, so as to purify the water more thoroughly and adapt to a wider range of water conditions. Attached Figure Description

[0078] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0079] Figure 1 This is a perspective view of a purification device according to an embodiment of the present invention. The purification device includes a main functional unit 1. To enable the main functional unit 1 to float and descend in water, a buoyancy device is connected to the main functional unit 1. In this embodiment, an airbag 2 is selected as the buoyancy device. In this embodiment, an annular airbag 2 is selected and horizontally arranged around the bottom of the main functional unit 1. When the airbag 2 is inflated, its buoyancy increases, supporting the main functional unit 1 to float upwards. When the airbag 2 is deflated, its buoyancy decreases, and the main functional unit 1, lacking sufficient support, freely descends under gravity. The annular airbag 2 arrangement allows for a more uniform support force on the main functional unit 1 in the horizontal direction, making the device less prone to tipping over. It also minimizes the area obstructed from the device's surface, thus having less impact on its operation. Furthermore, an air compressor 32 is provided to supply or depress air to the airbag 2 to achieve the inflation and deflation process.

[0080] The main functional device 1 includes a purification unit 12. The water in which the purification equipment is located must pass through the purification unit 12 to achieve the purification effect. Figure 3This is a cross-sectional view of the purification unit 12. In this embodiment, the purification unit 12 is cylindrical, with multiple densely distributed through holes 121 on its wall. The through holes 121 connect the water inside and outside the purification unit 12 and allow water to pass through. An outlet 122 is also provided at one end of the purification unit 12. To guide the flow of water through the purification unit 12, an axial flow pump 123 is provided at one end of the purification unit 12. Figure 3 As shown, one end of the axial flow pump 123 is connected to the internal space of the purification unit 12, and the other end is connected to the outlet 122. The axial flow pump 123 can pump water from the purification unit 12 to the outlet 122, so that the overall flow direction of the water is: entering from the through hole 121 in the cylinder wall, passing through the interior of the purification unit 12, being pumped to the axial flow pump 123, and finally flowing out from the outlet 122. The multiple through holes 121 on the surface of the purification unit 12 can have a certain effect on the uniform flow of the incoming water, that is, the flow pattern of the water passing through the purification unit 12 is more uniform, so that the water can be purified more fully and stably. The setting of this water flow direction makes the inlet surface larger, thereby making the maximum hydraulic load that the purification unit 12 can withstand greater.

[0081] To ensure the water passing through the purification unit 12 is purified, in this embodiment, the purification equipment operates in two modes: an emergency water purification mode and an ecological construction mode. The main functions of both modes are achieved through the dispensing pipe 125 and the lamp tube 124 installed within the purification unit 12. For example... Figure 6 As shown, the dispensing tube 125 is a hollow cylindrical tube, which is horizontally positioned at the center of the purification unit 12 and fixed by a bracket 126. It is coaxial with the cylindrical purification unit 12. The internal space of the tube is connected to the storage tank 33. The dispensing tube 125 is used to receive the treatment agent output from the storage tank 33. The tube wall has multiple densely distributed small holes 1251, which connect the hollow part of the dispensing tube 125 to the water outside the tube. The small holes 1251 can spray the treatment agent in the dispensing tube 125 into the nearby water. In addition, a lamp tube 124 is also provided in the purification unit 12. The lamp tube 124 is used to illuminate the nearby water. The lamp tube 124 is also horizontally positioned in the purification unit 12 and fixed by a bracket 126. Multiple lamp tubes are arranged around the dispensing tube 125 to make the illumination effect more sufficient.

[0082] The operating modes of the dispensing pipe 125 and the lamp 124 can be switched according to the working mode of the purification equipment: When the purification equipment is in emergency water purification mode, the treatment agent in the dispensing pipe 125 is hydrogen peroxide, chlorine dioxide solution, or ozone. The treatment agent is sprayed through the small hole 1251 to disinfect and purify the nearby water. At the same time, the light wavelength of the lamp 124 is adjusted to the ultraviolet band of 100-400nm to further disinfect the nearby water. When the purification equipment is in ecological construction mode, the treatment agent delivered by the storage tank 33 is probiotic liquid or algae liquid. The treatment agent is sprayed through the small hole 1251 to spread and reproduce bacteria or algae in the nearby water. At the same time, the light wavelength of the lamp 124 is adjusted to the visible light band of 400-760nm to assist the growth of the bacterial or algae liquid, and to improve the aquatic ecology by utilizing the growth characteristics of bacteria and algae.

[0083] To achieve automatic switching of the above-mentioned working modes, a central control device can be installed on the purification equipment to receive water quality information and control the working mode of the equipment. When the water quality information shows that the pollution level of the surrounding water body is not less than the first preset value (COD≥50mg / L), the central control device will adjust the purification mode to "emergency water purification mode"; when the water quality information shows that the pollution level of the surrounding water body is less than the first preset value (COD<50mg / L), the central control device will adjust the purification mode to "ecological construction mode".

[0084] like Figure 1 , Figure 2 As shown, in this embodiment, to ensure that the bacterial or algal liquid in the purification unit 12 stably performs its ecological construction function, a nano-aeration disc 13 is installed below the purification device. The air outlet surface of the nano-aeration disc 13 faces upward, and multiple discs are arranged horizontally to generate sufficient bubbles. The bubbles can rise freely through the interior of the purification unit 12, supplying gas to the bacteria or algae and promoting their growth, accelerating the purification efficiency, and further improving the purification effect. At the same time, the axis of the purification unit 12 is arranged horizontally so that the through holes 121 on its cylinder wall can receive bubbles to the maximum extent. In this embodiment, the nano-aeration disc 13 can also be connected to an air compressor 32, which can provide a sufficient gas source for the nano-aeration disc 13.

[0085] In this embodiment, the purification device also includes a solar photovoltaic panel 31. The panel surface of the solar photovoltaic panel 31 is arranged in a lotus shape, with its "petals" designed to receive natural sunlight for solar power generation. Furthermore, the panel surface can mimic the opening and closing of flower petals. On sunny days or windless nights, the "petals" open and rotate towards the sunlight; on rainy days or windy days, the "petals" close, providing working space for other facilities. In addition, the "petals" have a fluorescent effect at night, giving the solar photovoltaic panel 31 both power generation and aesthetic functions.

[0086] In order to enable the purification device to move horizontally in the water body and swim to different positions in the water body to carry out purification work, in this embodiment, propellers 4 are respectively arranged around the main functional device 1 in the horizontal direction. One or more propellers 4 can be selectively activated to propel the purification device to swim horizontally.

[0087] Based on the aforementioned purification equipment, this invention also describes a self-detection in-situ pollution purification method for river outfalls, such as... Figure 4 As shown, the cleaning method includes the following steps:

[0088] S100: The central control device receives the predicted discharge outlet location information from the main functional device 1, and the predicted discharge outlet location information corresponds to the water area of ​​the discharge outlet to be treated.

[0089] S200: The central control device determines the horizontal movement position and vertical height position of the main functional device 1 based on the predicted outlet position information, and sends the horizontal movement position and vertical height position to the submersible device and the propulsion device.

[0090] S300: The buoyancy device obtains the vertical height position and controls the main functional device 1 to rise or descend based on the vertical height position.

[0091] S400: The propulsion device obtains the horizontal movement position and controls the main functional device 1 to move horizontally according to the horizontal movement position.

[0092] This purification method utilizes the aforementioned central control device to receive predicted outlet location information, determine horizontal and vertical movement information, and control the submersible and propulsion devices accordingly. This allows the purification equipment to easily adjust its depth or horizontal position in the water, enabling more thorough water purification and adapting to a wider range of water conditions. In practice, steps S300 and S400 can be performed in reverse order or simultaneously. Furthermore, the predicted outlet location information can be sent to the central control facility via manual control equipment or external detection probes.

[0093] The specific control method of the buoyancy device is to adjust the volume of the airbag 2 to achieve the buoyancy function. Step S300 above also includes:

[0094] S310: The central control device controls the volume change of the airbag 2 to make the main functional device 1 float up or submerge.

[0095] Using airbag 2 as a buoyancy device, the main functional device 1 can be submerged and floated by controlling the volume of airbag 2. When airbag 2 is inflated, it can use its buoyancy to support the main functional device 1 to float upwards. When airbag 2 is deflated, the main functional device 1 can freely submerge under the action of gravity, and its control method is simpler. The above implementation method can also be adjusted according to the specific shape or setting of airbag 2.

[0096] To further expand the functionality of airbag 2, multiple airbags are provided in the horizontal circumferential direction of the main functional device 1, such as... Figure 5 As shown, the cleaning method includes:

[0097] S510: The central control device receives the vertical tilt information of the main functional device 1.

[0098] S520: The central control device determines the correction information based on the vertical tilt information, and controls the airbags 2 on the same side of the tilt direction to increase their volume accordingly based on the correction information.

[0099] By increasing the volume in the tilt direction along the circumference, the main functional device 1 receives greater support in that direction, thus achieving the tilt correction function. This utilizes the structural characteristics of the airbag 2, making it easier to correct the tilt position. This implementation method can be adopted as needed, extending the aforementioned buoyancy function and allowing for full utilization of the airbag 2.

[0100] The specific control method of the propulsion device is to activate the thruster 4 to achieve the horizontal movement function. Step S400 above further includes:

[0101] S410: The central control unit controls the start of the thruster 4 so that it pushes the main functional device 1 to move horizontally.

[0102] S420: The central control unit controls the shut-off of the thruster 4 so that the main functional device 1 gradually stops moving horizontally.

[0103] The central control unit controls the start of the thruster 4 to propel the main functional device 1 horizontally; the central control unit also controls the shutdown of the thruster 4 to gradually bring the main functional device 1 to a stop during horizontal movement. Using the thruster 4 as the propulsion device simplifies the control method, allows the thruster 4 to adapt to the underwater environment, and enables faster horizontal adjustment.

[0104] To further expand the functionality of the thruster 4, multiple thrusters 4 are provided in the horizontal circumferential direction of the main functional device 1. The above step S410 also includes:

[0105] S411: The central control device controls the activation of some of the thrusters 4 and controls the propulsion rate of the activated thrusters 4 so that the main functional device 1 moves horizontally at a constant or variable speed, along a straight line or a curve.

[0106] Specifically, four thrusters 4 are evenly arranged around the circumference of the main functional device 1. Their positions and number can be adjusted according to the shape or volume of the main functional device 1.

[0107] By setting an adjustable thruster 4 and using a central control device to control the activation of some thrusters 4, while adjusting the thrust rate of the activated thrusters 4, the main functional device 1 can move horizontally at a constant or variable speed, along a straight line or a curve. This optimizes the horizontal movement trajectory of the main functional device 1, making the path to the preset position shorter and the time shorter.

[0108] In addition, the main functional device 1 includes a purification unit 12, such as Figure 6 As shown, the cleaning method includes:

[0109] S610: The central control device receives water quality information, predicts the location of pollution outlets in the river, and drives the main functional device to operate near the river outlet.

[0110] S620: The central control device sets the working mode of the purification unit 12 to the ecological construction mode based on the water quality information, and sends the ecological construction mode command to the purification unit 12.

[0111] S630: The purification unit 12 acquires and outputs treatment agent to the nearby water body according to the instructions of the ecological construction mode.

[0112] The central control unit receives water quality information and sets an ecological construction mode for the purification unit 12, enabling it to switch operating modes according to water quality conditions. Its operation can adapt to the environment and accommodate complex water conditions. In practice, water quality information can be detected by adding detection probes and transmitted to the central control system. The operating modes of the purification unit 12 can be expanded to multiple modes as needed. For example, in addition to the ecological construction mode for the first water quality condition, an emergency water purification mode for the second water quality condition can be added, and switching between multiple modes can be achieved using the same control method described above.

[0113] Specifically, in S630, the treatment agent includes bacterial solution and / or algal solution. As a preferred embodiment, the bacterial solution and algal solution are output simultaneously in S630. This embodiment fully utilizes the growth characteristics of the bacterial / algal solution to decompose harmful substances in the water, thereby improving water quality and achieving the effect of ecological construction. In practical implementation, appropriate treatment agents can be used depending on the added operating mode or different water treatment requirements.

[0114] To aid in the growth of bacterial or algal solutions, the purification equipment also includes a nano-aeration disc 13. The purification method includes:

[0115] S710: The central control device receives water quality information, predicts the location of pollution outlets in the river, and drives the main functional device to operate near the river outlet.

[0116] S720: The central control device sets the working mode of the purification unit 12 to the ecological construction mode based on the water quality information, and sends an air supply command to the nano aeration disc 13.

[0117] S730: The nano-aeration disc 13 acquires and outputs nano-bubbles to the purification unit 12 according to the air supply command.

[0118] By setting up a nano-aeration disc 13 and controlling it to output nano-bubbles to the purification unit 12 in ecological construction mode, the gas required for the growth of bacterial or algal liquid is provided to the bacterial or algal liquid, thereby accelerating the growth process of the bacterial or algal liquid and further improving work efficiency.

[0119] The control method for the axial flow pump 123 in the aforementioned purification unit 12 includes:

[0120] S800: The central control device starts the axial flow pump 123 by controlling it, so that the axial flow pump 123 can pump water, so that the water flows into the purification unit 12 from the through hole 121 and flows out from the outlet 122.

[0121] The axial flow pump 123 controls the water flow direction to accelerate the water flow within the purification unit 12, thereby improving the purification efficiency.

[0122] In addition, the purification equipment includes solar photovoltaic panels 31, such as Figure 7 As shown, the control method for the solar photovoltaic panel 31 includes:

[0123] S910: The central control unit receives weather information, and the weather information corresponds to the water area of ​​the discharge outlet to be treated;

[0124] S920: The central control device sends the first or second weather information to the solar photovoltaic panel 31 based on the weather conditions;

[0125] S930: The solar photovoltaic panel 31 acquires and opens the panel surface based on the first weather information to generate solar power using the panel surface, while controlling the rotation of the panel surface so that the panel surface can always face the light source;

[0126] S940: Solar photovoltaic panel 31 obtains and closes the panel surface based on the weather information of the second day.

[0127] Specifically, when the central control device receives a weather forecast indicating ample sunshine, it sends the first weather information to the solar photovoltaic panel 31, allowing the panel to open and rotate towards the sun to fully receive solar energy. When the central control device receives a weather forecast indicating insufficient sunshine, it sends the second weather information to the solar photovoltaic panel 31, allowing the panel to retract and provide working space for other facilities. In practice, a detection probe can be added to monitor weather conditions and send weather information to the central control device.
