Since many solar PV power plant sites are located in desert areas, characterized by high dust levels and low rainfall, the accumulation of dust and dirt on solar panels over extended periods affects their light absorption and power generation efficiency. Therefore, maintaining the cleanliness of the PV panel surface is crucial for the power generation efficiency of solar PV power plants.

[0055] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0056] Solar panels in solar photovoltaic power plant sites located in desert areas accumulate dust and dirt over time, affecting their light absorption and power generation efficiency. Maintaining the cleanliness of the photovoltaic panel surface is crucial for the power generation efficiency of the solar photovoltaic power plant. Existing solar panel cleaning systems are ineffective and prone to secondary pollution. To address the problems of poor cleaning performance and secondary pollution in existing technologies, this invention provides a solar panel descaling system and method to overcome the shortcomings of existing technologies.

[0057] Example 1

[0058] Embodiment 1 of the present invention provides a solar panel descaling system, the system structure of which is described below. Figure 1 As shown, it includes: a dust cover 4, a walking mechanism 7 located below the dust cover, a cleaning device 1 located inside the dust cover, a monitoring and control system 6, an anti-static device 3, and an absorption device 2;

[0059] The monitoring and control system 6 is used to monitor the first dirt data of the solar panel, send a first control signal to the static electricity removal system based on the first dirt data, and / or send a second control signal to the cleaning device.

[0060] The static eliminator 3 is used to purge the solar panel according to the purging control parameters included in the received first control signal;

[0061] The cleaning device 1 is used to clean dirt on the solar panel according to the cleaning control parameters included in the received second control signal; the cleaning coverage width of the cleaning device is set according to the width of the solar panel.

[0062] Absorption device 2 is used to absorb dirt that is stirred up in the dust cover;

[0063] The walking mechanism 7 is used to drive the descaling system to move on the energy panel.

[0064] Existing robots do not thoroughly clean the solar panels, and the lack of dust control after cleaning leads to secondary pollution. While some automated cleaning devices require water to clean the panels, water is scarce in desert areas, making water supply difficult to establish and increasing cleaning costs, resulting in resource waste. Furthermore, these automated cleaning devices are complex, expensive to manufacture, and difficult to maintain, hindering widespread application. Existing technologies also lack static electricity removal, causing some dirt to adhere to the solar panels and remain difficult to clean. The system provided in this invention does not require water to clean the solar panels. It achieves cleaning through friction between the cleaning device and the panel. After cleaning, dust adheres to the panel under static electricity; a static electricity removal device blows the dust away. The system also includes a dust cover and a dust collection device to contain and absorb dust, minimizing secondary pollution and resulting in superior cleaning performance.

[0065] The monitoring and control system of this system detects the first dirt data of the solar panel and determines the operation to be performed based on the first dirt data, including but not limited to at least one of cleaning and static electricity removal. Optionally, if it is determined that the solar panel needs static electricity removal based on the first dirt data, a first control signal can be sent to the static electricity removal device to control the static electricity removal device to remove static electricity from the panel surface and reduce dust adsorption; optionally, if it is determined that the solar panel needs cleaning, a second control signal can be sent to the cleaning device to control the cleaning system to clean the solar panel; optionally, when it is determined that the solar panel needs both static electricity removal and cleaning, a first control signal can be sent to the static electricity removal device and a second control signal can be sent to the cleaning device to control the static electricity removal device to eliminate static electricity from the panel surface and to control the cleaning device to remove dirt from the panel surface. The monitoring and control system can intelligently control the cleaning device and the static electricity removal device to ensure that the solar photovoltaic panel reaches the optimal cleanliness state and thus operates in the best working state, improving power generation efficiency.

[0066] Optionally, the dust cover 4 in the above-mentioned solar panel descaling system includes: a top cover, oppositely arranged left and right side panels, and oppositely arranged front and rear side panels;

[0067] The cleaning device 1 is movably mounted on the bottom of the front panel;

[0068] The suction device 2 is installed on the left or right side panels, or the top cover, or the rear side panel of the dust cover;

[0069] The static eliminator 3 and the monitoring and control system 6 are installed on the upper surface of the dust cover.

[0070] A hem can also be installed at the bottom of the dust cover. The hem can be made of wear-resistant materials such as rubber to reduce friction and increase passability.

[0071] See Figure 1 As shown, the cleaning device 1 is schematically drawn. The cleaning coverage width of the cleaning device should be set according to the width of the solar panel to ensure that the cleaning device can clean every area of ​​the solar panel. The suction device 2 is set inside the dust cover, which can effectively collect the dirt inside the dust cover and prevent secondary pollution of the solar panel. The static elimination device 3 and the monitoring and control system 6 are set on the top cover of the dust cover. The monitoring and control system 6 monitors the dirt on the panel in real time and intelligently controls the operation of the solar descaling system. The static elimination device 3 can remove the dirt adsorbed on the panel surface, reduce the adsorption of dirt, and make the cleaning effect better.

[0072] Optionally, the monitoring and control system 6 described above is also used to receive the second dirt data of the suction device 2, and if the second dirt data meets the conditions for unloading dirt, send a third control signal to the suction device 2 to control the suction device 2 to unload dirt.

[0073] Optionally, the suction device 2 includes: a storage cavity and a sensor;

[0074] The storage cavity is used to collect dirt that rises from the dust cover and to perform dirt removal operations based on a third control signal;

[0075] The sensor is used to monitor the second dirt data in the receiving cavity in real time and send it to the monitoring and control system; the sensor includes at least one of a mass sensor for detecting the mass of dirt in the receiving cavity and a level sensor for detecting the height of dirt in the receiving cavity.

[0076] The number of storage devices 2 can be set according to the size of the solar descaling system to ensure that they can absorb the dirt raised inside the dust cover of the solar descaling system. Optionally, two storage devices can be set, one on each side. Figure 1 As shown in the diagram; optionally, a single storage device can be provided, for example, placed near the center inside the dust cover; or multiple devices can be provided, arranged in a certain way inside the dust cover to ensure that when one storage device cannot cover the entire space of the dust cover, multiple storage devices can work together to cover the entire space of the dust cover. The storage device can be installed on the left and right side panels of the dust cover, on the top cover surface of the dust cover, or on the rear side panel of the dust cover.

[0077] The cleaning device does not use water to clean the solar panels. Therefore, some dust will be trapped in the dust cover after cleaning the solar panels. This dust is collected by the collection chamber in the suction device. Sensors can be installed in the suction device to monitor the amount of dirt in the collection chamber, determining the effective volume of the chamber and the appropriate time for unloading. The sensors can be at least one of a mass sensor (detecting the mass of dirt in the collection chamber) and a level sensor (detecting the height of dirt in the collection chamber). The level sensor can be an ultrasonic sensor to monitor the level. For example, if the level in the collection chamber exceeds the effective height, unloading can be determined; or if the mass in the collection chamber exceeds its capacity, unloading can also be determined. Alternatively, both level and mass can be monitored, and unloading can be performed when requirements are not met. The suction device does not suck up dirt on the panel because, in reality, the solar panel is always at a certain angle to the ground. During the cleaning process, the dirt can fall along the inclined surface of the solar panel without needing to be sucked up and collected.

[0078] Optionally, the above-mentioned cleaning device includes a plurality of cleaning parts arranged along the length of the dust cover; in this application, when the solar descaling system is in operation, the length of the dust cover is consistent with the width of the solar panel.

[0079] The cleaning unit is used to adjust at least one of the cleaning position, cleaning direction, cleaning trajectory, and cleaning intensity based on the cleaning control parameters in the second control signal sent by the monitoring and control system.

[0080] Each cleaning unit may include an adjustment mechanism and a cleaning mechanism. The adjustment mechanism is mounted on the front panel and may be a connecting rod. The adjustment mechanism can drive the cleaning mechanism to rotate a certain angle or move a certain distance. The cleaning mechanism can consist of multiple cleaning brushes, multiple cleaning cloths, or multiple cleaning nozzles. Since the cleaning device is movably located at the bottom inside the dust cover, based on the cleaning control parameters in the second control signal sent by the monitoring and control system, at least one of the following can be adjusted: cleaning position, cleaning direction, cleaning trajectory, and cleaning intensity. For example, the cleaning device can activate one or more cleaning cloths at the cleaning position based on the cleaning control parameters of the second control signal; it can also control multiple cleaning units to adjust different directions and cleaning trajectories to clean every aspect of the solar panel, achieving comprehensive cleaning; if the monitoring and control system detects a large area of ​​dirt coverage, the cleaning intensity of the cleaning units can be increased to clean stubborn dirt. In short, based on the second control signal, at least one of the following must be adjusted to achieve comprehensive cleaning of the solar panel, ensuring optimal cleaning results. The cleaning mechanism can be adjusted by changing its position and angle to achieve at least one of the following: cleaning position, cleaning direction, and cleaning trajectory; and the cleaning intensity can be adjusted by changing the contact distance between the cleaning mechanism and the solar panel.

[0081] Optionally, the above-mentioned static eliminator 3 includes: an ion air nozzle 30 and a guide rail 31. A connecting mechanism is provided at one end of the ion air nozzle connected to the guide rail. The connecting mechanism drives the ion air nozzle to slide along the guide rail to change the blowing position.

[0082] The ion air nozzle is connected to the guide rail in a suspended manner. The ion air nozzle is used to adjust at least one of the purging position, purging angle and purging force based on the purging control parameters in the first control signal sent by the monitoring and control system.

[0083] Optionally, the guide rail is provided with air holes, and the air suspension connection between the guide rail and the ion air nozzle is achieved by filling the air holes with gas; or

[0084] A levitation electromagnet is installed on the guide rail, which enables magnetic levitation connection between the guide rail and the ion air nozzle.

[0085] The connection mechanism of the ion air nozzle is suspended from the guide rail, which can reduce drag during the sliding of the ion air nozzle. The connection mechanism does not directly contact the groove of the guide rail to prevent dust from accumulating in the groove of the guide rail, which could prevent the ion air nozzle from sliding normally.

[0086] The ion air blown by the ion air nozzles can eliminate static electricity on the solar panel. These nozzles can be activated when the solar panel descaling system is powered on, or during the cleaning process. The number of ion air nozzles can be selectively set according to actual needs. The ion air blown by the nozzles not only achieves the effect of eliminating static electricity but also effectively blows away dirt on the solar panel, resulting in better cleaning. Based on the blowing control parameters in the first control signal, the ion air nozzles of the static elimination device can adjust at least one of the following: blowing position, blowing angle, and blowing force. For example, after determining the blowing position, the nozzle moves to the cleaning position and blows ion air. Depending on the size of the cleaning position, the area covered by dirt, and the degree of dirt coverage, the blowing angle and blowing force of the ion air nozzles can be adjusted. The blowing force can be controlled by changing the output power of the ion air nozzles.

[0087] Optionally, a schematic diagram of the above monitoring and control system can be found in [reference needed]. Figure 3 As shown, it includes: a data acquisition unit 21, a data transmission unit 22, and a control unit 23.

[0088] Data acquisition unit 21 is used to collect first dirt data of solar panel; the first dirt data includes dirt distribution area, dirt coverage degree, dirt type and cleanliness degree;

[0089] Data transmission unit 22 is used to receive second dirt data sent by the absorption device; the second dirt data includes dirt mass data and dirt height data;

[0090] The control unit 23 is configured to determine the purging control parameters of the static elimination device based on the first dirt data, and generate a first control signal including the purging control parameters; determine the cleaning control parameters of the cleaning device based on the first dirt data, and generate a second control signal including the cleaning control parameters; and generate a third control signal based on the second dirt data to control the suction device to unload dirt.

[0091] Optional, control unit, specifically used for:

[0092] If the first dirt data exceeds the first data threshold, determine the blowing control parameters of the static removal device and send a first control signal to the static removal device to control the static removal device to remove static electricity from the solar panel based on the blowing control parameters; and determine the cleaning control parameters of the cleaning device and send a second control signal to the cleaning device to control the cleaning device to clean the solar panel based on the cleaning control parameters.

[0093] If it is determined that the second dirt data exceeds the second data threshold, a third control signal is sent to the absorption device to control the absorption device to perform the dirt unloading operation.

[0094] The data acquisition unit can use a camera or sensor to monitor the first dirt data of the solar panel. If the control unit determines that the first dirt data exceeds a first data threshold, it determines the purging control parameters and / or cleaning control parameters, and sends control signals to the static eliminator and / or cleaning device. The first data threshold can include one or more, and is specifically set for at least one first dirt data according to actual working needs. For example, if at least one of the dirt type and cleanliness level in the first dirt data exceeds the first dirt data threshold, purging control parameters can be generated and a first control signal can be sent to the static eliminator. The dirt type can be stubborn dirt and easy-to-clean dirt. Dirt with a cleaning time exceeding 4 seconds is defined as stubborn dirt, and dirt with a cleaning time not exceeding 4 seconds is defined as easy-to-clean dirt. In this case, the first data threshold for the dirt type can be set to 4 seconds. Similarly, a cleanliness level of 80%-100% is defined as clean, and dirt outside this range is defined as unclean. In this case, the first data threshold for the dirt type can be set to 80%-100%. When the dirt type data exceeds 4 seconds and the cleanliness data does not reach at least 80%-100%, the static eliminator can be controlled to work to eliminate static electricity and remove stubborn dirt. If at least one of the dirt distribution area, dirt coverage, and cleanliness in the first dirt data does not meet the first data threshold, cleaning control parameters can be generated and a first control signal can be sent to the cleaning device. When a dirt distribution area is detected on the panel and the dirt coverage in that area exceeds 5 mm and the cleanliness does not reach at least 80%-100%, the cleaning device can be controlled to work to clean the panel. If the dirt distribution area, dirt coverage, dirt type, and cleanliness in the first dirt data all exceed the first data threshold, purging control parameters and cleaning control parameters are generated, and a first control signal is sent to the static eliminator and a second control signal is sent to the cleaning device to control the static eliminator and the cleaning device to clean the panel and eliminate static electricity. The various units in the monitoring and control system work together to achieve intelligent control of the solar panel.

[0095] Optionally, the traveling mechanism includes two traveling units, each of which includes a flexible pulley and a mounting mechanism; the mounting distance between the two traveling units is adjustable.

[0096] The mounting mechanism is used to install the solar panel descaling system onto the bracket of the solar panel to be cleaned.

[0097] Flexible pulleys are used to drive the solar panel descaling system to move on the solar panel.

[0098] Optionally, the walking mechanism also includes a travel detection switch for detecting the position of the flexible pulley on the solar panel;

[0099] The monitoring and control system is also used to control the movement or stopping of the walking mechanism based on the position of the flexible pulley on the solar panel.

[0100] The adjustable installation spacing of the walking units allows the solar panel descaling system to adapt to solar panels of different widths, enhancing its versatility. The installation mechanism can be a rubber gripper or a soft hook, ensuring the flexible pulleys remain stable on the solar panel support as they move across the panel. The flexible pulleys can be configured with a variable wheelbase, further improving the system's maneuverability. Even when the solar panel support is not straight but curved, the flexible pulleys mounted on the support can still pass through.

[0101] A travel monitoring switch is installed on the walking mechanism, which can control whether the walking mechanism continues to move forward or backward, and also control the walking mechanism to stop, based on the detected position of the flexible pulley on the solar panel, thus facilitating the control of the movement position of the solar descaling system.

[0102] See the installation diagram of the solar panel descaling system in this embodiment. Figure 2 As shown, Figure 2 The solar panel descaling system is installed on the solar panel bracket 9. The system removes dirt from the solar panel along the inclined surface of the solar panel. The system has an ingenious structure, is easy to maintain, and has a good cleaning effect. It does not easily cause secondary pollution to the panel and can reduce dust entering the surrounding air and polluting the air.

[0103] In this embodiment, the system incorporates an antistatic device, a cleaning device, and a dust collection device within a dust cover. The dust cover effectively confines the dust's range, preventing it from settling on the solar panel surface and causing secondary pollution. Furthermore, this system eliminates the need for water for cleaning the solar panel, making it more environmentally friendly. The monitoring and control system sends a first control signal to the antistatic system and / or a second control signal to the cleaning device based on the first dirt data, achieving intelligent management of the solar panel descaling system. This high degree of automation significantly reduces labor intensity. The antistatic device receives the first control signal to remove static electricity from the solar panel and sweep away dirt. For stubborn dirt, the blowing force of the antistatic device can be increased, making it easier to remove. The cleaning device performs the main cleaning of the panel to maintain its cleanliness. The dust collection device absorbs dust from the dust cover, greatly reducing the probability of secondary pollution of the panel. The movable design of the antistatic device and cleaning device allows for adjustments to the blowing angle and force under the control of the first and / or second control signals, achieving comprehensive cleaning of the panel and resulting in better cleaning performance.

[0104] Example 2

[0105] Embodiment 2 of the present invention provides a method for descaling solar panels, the process of which is as follows: Figure 4 As shown, it includes the following steps:

[0106] Step S201: The walking mechanism drives the descaling system to move on the solar panel, and the suction device sucks up the dirt raised in the dust cover.

[0107] Step S202: The monitoring and control system monitors the first dirt data of the solar panel; sends a first control signal to the static elimination system to the static elimination device based on the first dirt data, so that the static elimination device blows the solar panel according to the purging control parameters included in the received first control signal; and / or sends a second control signal to the cleaning device based on the first dirt data, so that the cleaning device cleans the dirt on the solar panel according to the cleaning control parameters included in the received second control signal.

[0108] The monitoring and control system in step S202 above also includes:

[0109] The system receives second dirt data from the suction device. If the second dirt data exceeds a second data threshold, it sends a third control signal to the suction device to control the suction device to unload the dirt.

[0110] The method described in this embodiment of the invention uses a walking mechanism to drive the solar panel descaling system to move on the solar panel.
