It is difficult to ensure the timeliness and consistency of cleaning due to the constraints of personnel working time and efficiency, which makes it easy for dust and other pollutants to accumulate on the surface of the module for a long time, affecting the power generation efficiency. Mechanical automatic cleaning devices also have many shortcomings. Their structure is single and it is difficult to adapt to changes in different environmental conditions and pollution conditions. In complex climate environments such as strong wind and sand, high humidity or frequent bird activities, they cannot effectively deal with various pollution conditions. Moreover, their cleaning methods may cause scratches and damage to the surface of the module, affecting the service life and power generation performance of the module. At the same time, the cleaning effect of stains with strong adhesion (such as bird droppings, oil stains, etc.) and fine dust particles is limited, and it is difficult to ensure that the surface of the module always maintains good cleanliness. This is mainly due to technical limitations. The sensor application of existing cleaning technology is not comprehensive and accurate. It only relies on simple humidity or light sensors to judge the cleaning time, and cannot accurately perceive various factors such as dust concentration, wind direction and wind speed, resulting in unreasonable cleaning strategies. At the same time, the design concept is limited, focusing on a single cleaning method, not integrating multiple effective means, lacking intelligent adaptive control, and cannot flexibly adjust cleaning parameters and methods.

DETAILED DESCRIPTION
[0049] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The embodiments of the present invention include but are not limited to the following embodiments.
[0050] Example
[0051] like Figure 1 As shown, the present invention discloses an intelligent adaptive cleaning system for photovoltaic components, including an environmental sensing module for detecting the cleaning status of the photovoltaic components, an intelligent cleaning module connected to the environmental sensing module for performing a cleaning function, an adaptive control connected to the environmental sensing module for controlling the intelligent cleaning module, and an energy recovery module connected to the intelligent cleaning module for realizing energy recovery and feeding back power to the environmental sensing module.
[0052] In this embodiment, the environment perception module is specifically:
[0053] Dust concentration sensor: uses the principle of laser scattering to accurately measure the concentration of dust particles in the air near the component surface. When the laser irradiates the dust particles in the air, the dust concentration is calculated based on information such as the intensity and angle of the scattered light.
[0054] Humidity sensor: monitors the ambient humidity in real time, as humidity has an important impact on the adhesion of dust and the formation of stains.
[0055] Rainfall sensor: Accurately detects whether there is rainfall and the amount of rainfall.
[0056] Wind direction and speed sensor: Obtain wind direction and speed information to optimize cleaning strategies and utilize the power of natural wind during cleaning.
[0057] Image recognition sensor: By taking images of the component surface, the sensor uses a convolutional neural network to process the collected images. After training with a large number of samples, it can accurately distinguish the type of stains (such as dust, bird droppings, leaves, etc.), distribution range and degree of contamination, and accurately mark their location and range in the image.
[0058] In this embodiment, the sensor transmits the collected data to the adaptive control module in real time through the wireless communication module.
[0059] like Figure 2 As shown, in this embodiment, the environment perception module 2, the adaptive control module 3, the energy recovery module 4, and the intelligent cleaning module are all installed on the photovoltaic module 1. The intelligent cleaning module includes an ultrasonic vibration cleaning subsystem 5, an intelligent jet cleaning subsystem 6, a flexible rotating cleaning brush system 9, an ultrasonic transducer 8, a negative pressure suction device 11, and a nozzle 10 installed on the photovoltaic module 1; wherein, the ultrasonic vibration cleaning subsystem 5 realizes ultrasonic vibration cleaning through the ultrasonic transducer 8; the image recognition sensor 7 recognizes the stains, the intelligent jet cleaning subsystem 6 cleans the stains by spraying a cleaning agent through a nozzle 10, and recovers the residual substances by using the negative pressure suction device 11, and finally wipes and cleans by using the flexible rotating cleaning brush system.
[0060] Specifically, ultrasonic vibration cleaning: a special ultrasonic transducer is installed on the surface of the component. When powered on, the transducer generates high-frequency ultrasonic vibrations, which loosen and detach the dust and stains on the surface of the component under the action of vibration. This cleaning method has a good cleaning effect on fine dust particles and stains with strong adhesion, and will not cause damage to the surface of the component.
[0061] Smart jet cleaning: For stubborn stains such as bird droppings and oil stains, the smart jet cleaning system is equipped. The system automatically locates the stains based on the detection results of the image recognition sensor and accurately controls the spray volume and pressure of the detergent. The detergent uses an environmentally friendly and efficient formula that can quickly decompose and remove stubborn stains. After jet cleaning, the negative pressure suction device is used to promptly suck and recover the remaining stains and detergent to prevent secondary pollution.
[0062] Flexible rotating cleaning brush: The bristles of the cleaning brush are made of special soft material, which can effectively remove various stains without scratching the surface of the component. The rotation speed and angle of the cleaning brush can be intelligently adjusted according to the data provided by the environmental perception module and the instructions of the adaptive control module. For example, when the wind speed is high, the rotation speed of the cleaning brush is appropriately reduced to avoid poor cleaning effect or additional pressure on the component due to the influence of wind; when the stains are unevenly distributed, the angle of the cleaning brush is adjusted to ensure comprehensive and even cleaning of the component surface.
[0063] Cleaning process example: When the environmental perception module detects that there is a lot of dust on the surface of the component and the dust is distributed relatively evenly, the intelligent cleaning module first activates the ultrasonic vibration cleaning technology to loosen the dust; if the image recognition sensor finds local stubborn stains, such as bird droppings, the intelligent jet cleaning system will spray an appropriate amount of detergent at the stain location for cleaning, and then activate the negative pressure suction device to recover the residual material, and finally use the flexible rotating cleaning brush for further wiping and cleaning to ensure that the component surface is clean.
[0064] The adaptive control module establishes a cleaning decision model based on an intelligent algorithm combining fuzzy logic and neural networks. The model comprehensively considers multiple factors such as dust concentration, humidity, rainfall, wind direction and speed, stain type and pollution degree, and generates the optimal cleaning strategy in real time.
[0065] Control strategy example: When the dust concentration is high and the humidity is low, a combination of ultrasonic vibration cleaning and intelligent jet cleaning is preferred, and the working parameters of the cleaning device are adjusted according to the wind speed to improve cleaning efficiency. When the rainfall is heavy, the control module will suspend the cleaning operation and use rainwater to naturally rinse the component surface, while adjusting the inclination angle of the component to ensure that rainwater can successfully carry away stains.
[0066] During the cleaning process, the energy generated by the vibration and airflow movement on the surface of the photovoltaic module is recovered. For example, under the action of ultrasonic vibration cleaning and natural wind, the mechanical vibration energy and airflow kinetic energy are converted into electrical energy through micro energy collectors (such as piezoelectric energy collectors and electromagnetic energy collectors) installed on the module frame or cleaning device, and stored in energy storage devices (such as supercapacitors or rechargeable batteries).
[0067] Energy application and integration: The recovered energy is used to power the sensors in the environmental perception module, the microprocessor in the adaptive control module, and some low-power devices in the intelligent cleaning module, reducing the dependence on external power supplies, and reducing the energy consumption and operating costs of the system. At the same time, the energy recovery module can also be integrated with the overall energy management system of the photovoltaic power station to achieve optimal utilization and allocation of energy. For example, when the power in the energy storage device reaches a certain threshold, the recovered energy can be used to power the cleaning system first, and then switch to the external power supply or the output power of the photovoltaic module when the energy is insufficient.
[0068] The algorithm flow of each module in this embodiment is as follows:
[0069] 1. Environmental perception module algorithm flow:
[0070] The dust concentration sensor uses the principle of laser scattering to measure the concentration of dust particles in the air near the component surface, calculates the dust concentration based on information such as the intensity and angle of the scattered light, and outputs the data.
[0071] The humidity sensor monitors the ambient humidity in real time and outputs humidity data.
[0072] The rainfall sensor accurately detects whether there is rainfall and the amount of rainfall, and outputs rainfall information data.
[0073] The wind direction and wind speed sensor obtains wind direction and wind speed information and outputs wind direction and wind speed data.
[0074] The image recognition sensor captures the component surface image and uses the convolutional neural network to process the collected image, distinguish the stain type, distribution range and degree of contamination, mark its position and range in the image, and output the stain information data.
[0075] The data collected by all the above sensors are transmitted to the adaptive control module in real time through the wireless communication module.
[0076] 2. Intelligent cleaning module algorithm process:
[0077] Receive instructions from the environment perception module and the adaptive control module.
[0078] If the environmental sensing module detects that there is a lot of dust on the surface of the component and it is evenly distributed, the ultrasonic vibration cleaning technology is activated to loosen the dust.
[0079] If the image recognition sensor finds local stubborn stains, such as bird droppings, the intelligent jet cleaning system will spray an appropriate amount of detergent at the stain location for cleaning, and then start the negative pressure suction device to recover the residual substances.
[0080] Finally, use a flexible rotating cleaning brush to further wipe and clean to ensure that the component surface is clean.
[0081] The rotation speed and angle of the cleaning brush are intelligently adjusted based on the data provided by the environmental perception module and the instructions of the adaptive control module, such as reducing the rotation speed when the wind speed is high and adjusting the angle when the stains are unevenly distributed.
[0082] 3. Adaptive control module algorithm flow:
[0083] Receive data transmitted by the environmental sensing module, including information such as dust concentration, humidity, rainfall, wind direction and speed, stain type and pollution degree.
[0084] Establish a cleaning decision model based on an intelligent algorithm combining fuzzy logic and neural networks
[0085] Comprehensively consider multiple factors and generate the optimal cleaning strategy in real time. When the dust concentration is high and the humidity is low, the combination of ultrasonic vibration cleaning and intelligent jet cleaning is preferred, and the working parameters of the cleaning device are adjusted according to the wind speed; when the rainfall is heavy, the cleaning operation is suspended, and the tilt angle of the components is adjusted to use rainwater for natural washing.
[0086] Send cleaning strategy instructions to the smart cleaning module.
[0087] 4. Energy recovery module algorithm flow:
[0088] During the cleaning process, the energy generated by the vibration of the photovoltaic panel surface and the movement of air flow is used.

[0090] Storing electrical energy in an energy storage device (such as a supercapacitor or rechargeable battery).
[0091] When the amount of electricity in the energy storage device reaches a certain threshold, the recovered energy is used first to power the sensors in the environmental perception module, the microprocessor in the adaptive control module, and some low-power devices in the intelligent cleaning module; when the energy is insufficient, it switches to the output power of the external power supply or the photovoltaic module.
