[0061] The above drawings illustrate specific embodiments of the present disclosure, which will be described in more detail below. These drawings and textual descriptions are not intended to limit the scope of the present disclosure in any way, but rather to illustrate the concepts of the present disclosure to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0062] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0063] Before introducing the embodiments of the present application, the application background of the embodiments of the present application is first explained:

[0064] When photovoltaic panels are in operation for a long time, dust will accumulate on their surface, and they need to be cleaned frequently, especially in windy and sandy areas, otherwise the power generation efficiency will be affected. Photovoltaic panels are easily affected by rain and snow in winter, and their surfaces may be covered with ice or snow, which will seriously reduce the power generation efficiency. Centralized photovoltaic power stations can be maintained manually on a regular basis, but passive wireless monitoring equipment or other small devices with built-in photovoltaic panels are rarely cleaned and maintained regularly, especially in uninhabited areas such as mountainous areas and Gobi Desert. Due to the high maintenance cost, they are basically not maintained after installation.

[0065] For dust removal of photovoltaic panels, the following are commonly used dust removal methods and the problems of each method:

[0066] 1. Personnel cleaning is effective, but regular maintenance costs are high and it is not suitable for operations in unmanned areas;

[0067] 2. Using a wiper structure to regularly clean dust and snow has a good cleaning effect, but the mechanical structure is complex and the cost is high. In addition, long-term operation will be affected by wind and sand, rust, aging of rubber strips, etc., and the probability of failure is high;

[0068] 3. The solution of increasing the tilt angle of the photovoltaic panel by mechanical rotation to remove snow also has the characteristics of complex mechanical structure, high cost, poor reliability, and poor dust removal effect. This solution relies on the weight of the snow to remove snow, and the snow removal effect is not good when the snow is thin or slightly frozen.

[0069] 4. Air wiper solutions, hot air snow removal, detonation snow removal solutions, etc. rely on airflow to clear snow, which are costly and complex in structure. Detonation snow removal also requires methane fuel and is not suitable for mass production.

[0070] In response to the technical problems existing in the prior art, the inventors of this application have the following idea: common mechanical structures tend to fail due to age. If a vibration component can be set on the photovoltaic panel, which drives the photovoltaic panel to vibrate after being activated, this vibration component does not have a complex mechanical structure, thus avoiding the possibility of failure. Different vibration frequencies can be used for different pollution, so that efficient cleaning can be carried out. Accordingly, some meteorological data acquisition elements can be used to obtain meteorological data, so as to process the meteorological data and obtain the corresponding pollution conditions, thereby adjusting the vibration frequency of the vibration component, etc., thereby solving the corresponding technical problems.

[0071] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0072] Figure 1 Schematic diagram of the structure of the photovoltaic panel cleaning device provided in the embodiment of the present application Figure 1 ,like Figure 1As shown, the photovoltaic panel cleaning device includes: a photovoltaic panel, a vibration device, a control device, and a first unit;

[0073] Optionally, the first unit is used to obtain current meteorological data in the environment where the photovoltaic panel is located;

[0074] In the corresponding implementation, the dust accumulation on the photovoltaic panels is closely related to environmental factors. By obtaining the current meteorological data of the environment in which the photovoltaic panels are located, corresponding dust removal methods can be adopted according to different meteorological data.

[0075] Meteorological data includes but is not limited to the following: sandstorm meteorological data, snowfall meteorological data, freezing rain meteorological data, pollution-free meteorological data, etc.

[0076] Among them, sandstorm meteorological data include: floating dust, blowing sand, sandstorm, strong sandstorm, and extremely strong sandstorm; snowfall meteorological data include: light snow, light to moderate snow, moderate snow, moderate snow to heavy snow, heavy snow, heavy to blizzard, and blizzard; freezing rain meteorological data include: light freezing rain, moderate freezing rain, and heavy freezing rain; pollution-free meteorological data include: clear, cloudy to clear, sunny to cloudy, and strong winds.

[0077] In one possible implementation, the first unit is a wireless communication module and / or a micrometeorological sensor;

[0078] Type 1: The wireless communication module is used to obtain the current meteorological data corresponding to the positioning information from the server based on the positioning information of the photovoltaic panel;

[0079] Under this implementation, the photovoltaic panel cleaning device can be designed with a satellite positioning module, or the location information of the area where the photovoltaic panel is located can be stored in advance in the memory of the photovoltaic panel cleaning device. The wireless communication module then sends the location information to the server. The server queries the meteorological data of the area where the photovoltaic panel is located based on the location information, and the wireless communication module receives the meteorological data.

[0080] Type 2: Micro-meteorological sensors are used to collect current meteorological data in the environment where the photovoltaic panels are located.

[0081] In this implementation, micro-meteorological sensors measure various meteorological parameters in their environment, such as temperature, humidity, air pressure, wind speed, etc. The sensing elements inside the sensor generate corresponding electrical signals based on different parameters, and these electrical signals represent different meteorological data.

[0082] It should be understood that the frequency or period of collecting current meteorological data in the environment where the photovoltaic panel is located can be a system default, or selected by the user during installation, or set based on experience according to subsequent dust removal effects.

[0083] Optionally, the controller is configured to determine first target vibration information of the vibration device in a preset first response strategy based on current meteorological data, the first response strategy carrying vibration information corresponding to different meteorological data, the vibration information including vibration frequency and / or vibration intensity;

[0084] As an example, Table 1 below is a schematic table of a possible first response strategy provided in an embodiment of the present application. It does not exhaust all possibilities and is only provided as an example (taking vibration frequency as an example, and intensity takes the default value).

[0085] Table 1

[0086] Weather data Vibration information Dust Vibrate once for 3 seconds, once every 5 hours Blowing sand Vibrate for 3 seconds at a time, once every 1 hour sandstorm Vibrate for 3 seconds at a time, every 15 minutes strong sandstorm Vibrate for 3 seconds at a time, with an interval of 5 minutes Extremely severe sandstorm Vibrate for 3 seconds at a time, with an interval of 2 minutes light snow Vibrate for 5 seconds at a time, every 30 minutes light to moderate snow Vibrate for 5 seconds at a time, every 20 minutes moderate snow Vibrate for 5 seconds at a time, every 15 minutes moderate to heavy snow Vibrate for 5 seconds at a time, every 10 minutes heavy snow Vibrate for 5 seconds at a time, and every 5 minutes Big as Blizzard Vibrate for 5 seconds at a time, with an interval of 2 minutes Blizzard Vibrate for 5 seconds at a time, with an interval of 1 minute sunny Vibrate for 5 seconds each time, once a day

[0087] In a possible implementation, if the current meteorological data obtained through the wireless communication module is light to moderate snow, it can be determined that the first target vibration information is a vibration of 5 seconds at an interval of 20 minutes.

[0088] It should be understood that the higher the vibration frequency, the better the dust removal effect; the higher the vibration intensity, the better the dust removal effect; the corresponding vibration frequency and / or vibration intensity should be adopted considering the actual situation of the photovoltaic panel installation structure and the degree of pollution.

[0089] Optionally, a vibration device is connected below the photovoltaic panel to drive the photovoltaic panel to vibrate according to the first target vibration information.

[0090] In this implementation, the vibration device is connected to the bottom of the photovoltaic panel through a rigid structure. For example, it can be installed on the bracket of the photovoltaic panel. After the control device determines the first target vibration information, the vibration device is controlled to vibrate according to the first target vibration information, thereby driving the photovoltaic panel to vibrate, so as to achieve the effect of vibration to remove pollutants on the surface of the photovoltaic panel.

[0091] In a possible implementation, the vibration device is a vibration motor, which is provided with a waterproof and dustproof protective cover, and the vibration motor is installed on a bracket of the photovoltaic panel.

[0092] For example, Figure 2 This is a schematic diagram of a vibration motor installation provided in an embodiment of the present application. Figure 2 As shown, the schematic diagram includes: a vibration motor and a photovoltaic panel.

[0093] Optionally, the surface of the photovoltaic panel is provided with a hydrophobic antifouling film.

[0094] For example, Figure 3 This is a schematic diagram of laying a hydrophobic antifouling membrane provided in an embodiment of the present application. Figure 3 As shown, the schematic diagram includes: a hydrophobic antifouling film and a photovoltaic panel.

[0095] Should Figure 3In the embodiment, the hydrophobic antifouling membrane can be provided in the form of pieces, and in the actual implementation process, the form of the provision is not limited.

[0096] With the implementation of this hydrophobic antifouling film, the surface of the photovoltaic panel has a high degree of hydrophobicity, making it difficult for water droplets to adhere to the surface of the photovoltaic panel, reducing the occurrence of ice on the photovoltaic panel surface. In addition, water droplets roll down the surface in a spherical shape, carrying away impurities such as dust and dirt, thereby reducing surface contamination and making it easier to clean the surface. In addition, the hydrophobic antifouling film can reduce the wettability of the photovoltaic panel surface, preventing water droplets from remaining and absorbing light, thereby improving light transmission efficiency, which has a significant improvement effect on photovoltaic panels that require light transmission. In addition, the hydrophobic antifouling film can enhance the weather resistance of the protected photovoltaic panel surface, preventing moisture and other contaminants from adhering to the surface, thereby reducing the risk of oxidation, corrosion, and surface degradation. In addition, due to its hydrophobic and antifouling properties, the surface covered with the hydrophobic antifouling film is relatively easy to clean and will not be re-contaminated for a long time, which can reduce the frequency and cost of maintaining and cleaning the photovoltaic panel.

[0097] The photovoltaic panel cleaning device provided in an embodiment of the present application includes a photovoltaic panel, a vibration device, a control device, and a first unit; the first unit is used to obtain current meteorological data of the environment in which the photovoltaic panel is located; the controller is used to determine first target vibration information of the vibration device in a preset first response strategy based on the current meteorological data, the first response strategy carrying vibration information corresponding to different meteorological data, the vibration information including vibration frequency and / or vibration intensity; the vibration device is connected to the bottom of the photovoltaic panel and is used to drive the photovoltaic panel to vibrate according to the first target vibration information. In this technical solution, the vibration unit is controlled by real-time meteorological data to drive the photovoltaic panel to achieve decontamination of the photovoltaic panel, thereby increasing dust removal efficiency, and avoiding the problem of fragile dust removal structure existing in the prior art.

[0098] Based on the above embodiments, Figure 4 Schematic diagram of the structure of the photovoltaic panel cleaning device provided in the embodiment of the present application Figure 2 ,like Figure 4 As shown, the photovoltaic panel cleaning device further includes: a second unit;

[0099] The second unit is used to obtain current image information of the photovoltaic panel surface and / or the surrounding area of ​​the photovoltaic panel;

[0100] In this implementation, the installation position of the second unit is not limited, and image information of the photovoltaic panel surface can be obtained, and image information of the photovoltaic panel periphery can also be obtained.

[0101] The current screen information includes pollution information, and different pollution information may correspond to different pollution levels, pollutants, and the like.

[0102] The second unit may be an image acquisition device such as a camera.

[0103] The control device is used to process the current image information to obtain target pollution information and determine the second target vibration information of the vibration device in a preset second response strategy, wherein the second response strategy carries vibration information corresponding to different pollution information;

[0104] In this implementation, the current screen information is processed to obtain pollutant information corresponding to the current screen information. The pollutant information may be the pollutant type and / or pollution level, etc., and then the second target vibration information of the vibration device is determined based on the second response strategy.

[0105] As an example, Table 2 below is a schematic table of a possible second response strategy provided in an embodiment of the present application. It does not exhaust all possibilities and is only provided as an example (taking vibration frequency as an example, and intensity takes the default value).

[0106] Table 2

[0107] Pollution Information Vibration information Light pollution Vibrate for 3 seconds at a time, once every 6 hours Moderate pollution Vibrate once for 3 seconds, once every 3 hours Severe pollution Vibrate for 3 seconds at a time, once every 1 hour Dust accumulation Vibrate for 3 seconds snow Vibrate for 5 seconds

[0108] It should be understood that the processing of vibration information for pollutant types can be carried out by obtaining image information of the photovoltaic panel surface through a camera at certain time intervals, and then the control device performs corresponding processing on the image information and then controls the vibration device.

[0109] In a possible implementation, after the camera acquires the current image information, the control device processes the current image information and obtains that there is snow on the surface of the photovoltaic panel. Then, the second target vibration information can be determined to be vibration for 5 seconds.

[0110] The vibration device is used to drive the photovoltaic panel to vibrate according to the second target vibration information.

[0111] In this implementation, the vibration device receives the relevant instruction of the second target vibration information sent by the control device, and starts vibration for 5 seconds to drive the photovoltaic panel to vibrate to clear the snow on the surface of the photovoltaic panel.

[0112] The photovoltaic panel cleaning device provided in an embodiment of the present application further includes: a second unit; the second unit is used to obtain current image information of the photovoltaic panel surface and / or the surrounding area of ​​the photovoltaic panel; a control device is used to process the current image information to obtain target pollution information, and determine second target vibration information of the vibration device in a preset second response strategy, the second response strategy carrying vibration information corresponding to different pollution information; the vibration device is used to drive the photovoltaic panel to vibrate according to the second target vibration information. In this technical solution, by obtaining the current image information of the photovoltaic panel surface and / or the surrounding area of ​​the photovoltaic panel, the corresponding vibration information is determined to control the vibration device to remove contaminants from the photovoltaic panel, thereby increasing dust removal efficiency, etc.

[0113] To sum up, the following is a feasible example: Figure 5 Schematic diagram of the structure of the photovoltaic panel cleaning device provided in the embodiment of the present application Figure 3 ,like Figure 5 As shown, the device includes: a photovoltaic system, a main control system, and external expansion.

[0114] As a possible implementation, the photovoltaic system includes: a vibration motor rigidly connected to the photovoltaic panel mounting bracket, and a photovoltaic panel rigidly connected to the photovoltaic panel mounting bracket;

[0115] The main control system includes: a processor unit and an image analysis unit (i.e., the functional division of the control device), a camera, a Global Navigation Satellite System (GNSS) satellite positioning unit, a third-generation mobile communication technology (3G) / fourth-generation mobile communication technology (4G) / fifth-generation mobile communication technology (5G) wireless communication unit (i.e., wireless communication module), a Recommended Standard 485 (RS485) serial bus, a charging management system, a battery, a power supply system, etc.

[0116] External expansion includes: micro-meteorological sensors.

[0117] and a system platform (i.e., a server) connected to the wireless communication unit.

[0118] The above achieves: 1. Effective cleaning - The anti-fouling membrane significantly reduces the adhesion of rain, snow, and dust. Combined with the powerful vibration of the motor and the tilt of the photovoltaic panel, the cleaning effect is excellent. 2. High reliability - The entire system has no moving parts, and the vibration motor is housed in a waterproof housing, ensuring long-term stable operation, unaffected by dust, rain, and snow. 3. Low cost - The anti-fouling membrane and vibration motor of the photovoltaic panel have extremely low material costs. The control device functions can be implemented using existing resources of the monitoring host or configured independently. 4. Low power consumption - Under normal conditions, daily dust accumulation on the photovoltaic panel surface is negligible, and the panel vibrates only once a day for 3 seconds, resulting in negligible power consumption. Even in heavily polluted weather, with vibration every half hour, the daily power consumption is less than 0.4Wh (motor power is 9W).

[0119] The implementation of this embodiment is similar to the technical solution of the above-mentioned embodiment, and is an implementation of the solution involved in the embodiment of this application, and its technical effect is also as described above.

[0120] Based on the above embodiments, Figure 6 Schematic diagram of the photovoltaic panel cleaning method provided in the embodiment of the present application Figure 1 ,like Figure 6 As shown, the method is applied to the control device in the above embodiment, including:

[0121] Step 61: Obtain current meteorological data of the environment where the photovoltaic panel is located;

[0122] In this step, the control device obtains the current meteorological data of the environment in which the photovoltaic panel is located through the wireless communication module and / or the micro-meteorological sensor.

[0123] The meteorological data include but are not limited to the following: sandstorm meteorological data, snowfall meteorological data, freezing rain meteorological data, pollution-free meteorological data, etc.

[0124] Among them, sandstorm meteorological data include: floating dust, blowing sand, sandstorm, strong sandstorm, and extremely strong sandstorm; snowfall meteorological data include: light snow, light to moderate snow, moderate snow, moderate snow to heavy snow, heavy snow, heavy to blizzard, and blizzard; freezing rain meteorological data include: light freezing rain, moderate freezing rain, and heavy freezing rain; pollution-free meteorological data include: clear, cloudy to clear, sunny to cloudy, and strong winds.

[0125] Step 62: Determine first target vibration information of the vibration device in a preset first response strategy based on current meteorological data;

[0126] The first response strategy carries vibration information corresponding to different meteorological data, and the vibration information includes vibration frequency and / or vibration intensity;

[0127] In this step, different meteorological data correspond to different vibration information of the vibration device, so as to adopt a dust removal strategy for pollutants on the surface of the photovoltaic panel under different meteorological data.

[0128] That is, the corresponding relationship in the first response strategy can be set by the user based on experience, saved in the memory of the photovoltaic panel cleaning device, and called by the control device after obtaining the current meteorological data to determine the corresponding first target vibration information.

[0129] The setting of the first response strategy can be found in Table 1.

[0130] Step 63: Control the vibration device to drive the photovoltaic panel to vibrate according to the first target vibration information.

[0131] In this step, after the control device determines the first target vibration information, the control device controls the vibration device to vibrate according to the first target vibration information, thereby driving the photovoltaic panel to vibrate, so as to achieve the effect of vibrating and removing pollutants on the surface of the photovoltaic panel.

[0132] Optionally, instead of using the above method, the vibration device may be controlled directly according to the third target vibration information to drive the photovoltaic panel to vibrate; the third target vibration information is vibration information corresponding to the pollution level of the environment in which the photovoltaic panel is located, which is pre-configured.

[0133] In one possible implementation, during equipment installation, on-site construction personnel determine the local pollution level based on environmental conditions, corresponding to light, moderate, and heavy levels. These pollution levels are then configured in the main controller, and the pollution level configuration can be modified later by remotely sending it through the platform.

[0134] For example, light pollution: one vibration for 3 seconds, once every 6 hours; moderate pollution: one vibration for 3 seconds, once every 3 hours; heavy pollution: one vibration for 3 seconds, once every 1 hour.

[0135] The photovoltaic panel cleaning method provided in an embodiment of the present application obtains current meteorological data from the photovoltaic panel's environment and, based on this data, determines a first target vibration information for a vibrating device within a preset first response strategy. The first response strategy carries vibration information corresponding to different meteorological data, including vibration frequency and / or vibration intensity. Based on the first target vibration information, the vibrating device is then controlled to vibrate the photovoltaic panel. In this technical solution, the vibrating device is controlled by real-time meteorological data to drive the photovoltaic panel, thereby achieving decontamination of the photovoltaic panel and increasing dust removal efficiency. The problem of fragility of the dust removal structure, which is common in existing technologies, is avoided.

[0136] Based on the above embodiments, Figure 7 Schematic diagram of the photovoltaic panel cleaning method provided in the embodiment of the present application Figure 2 ,like Figure 7 As shown, the method is applied to the control device in the above embodiment, and the method further includes:

[0137] Step 71: Acquire current image information of the photovoltaic panel surface and / or the surrounding area of ​​the photovoltaic panel;

[0138] In this step, the current image information of the photovoltaic panel surface and / or the surrounding area of ​​the photovoltaic panel is collected by a device such as a camera, and the control device obtains the current image information.

[0139] Optionally, one implementation of step 71 may be: when the vibration frequency and / or vibration intensity in the first target vibration information is greater than a preset threshold, obtaining current image information of the photovoltaic panel surface and / or the periphery of the photovoltaic panel.

[0140] In the above implementation, when the vibration frequency and / or vibration intensity are too high, in order to avoid power consumption and other situations, the current image information of the photovoltaic panel surface and / or the surrounding area of ​​the photovoltaic panel can be collected through a camera to avoid problems caused by errors in meteorological data collection.

[0141] At this time, subsequent dust removal work is performed based on the acquired current picture information.

[0142] Step 72: Process the current image information to obtain target pollution information, and determine second target vibration information of the vibration device in a preset second response strategy;
