DETAILED DESCRIPTION OF THE EMBODIMENTS

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0034] As Figure 1 shown, a solar photovoltaic panel automatic dust cleaning system includes: a base station 1, an autonomous driving cleaning vehicle 2, a robotic arm 3, a cleaning module, an identification module 4, and a communication module 5.

[0035] The base station 1 and the autonomous driving cleaning vehicle 2, the base station 1 is used to monitor the power generation efficiency of the solar photovoltaic panel, and when the detected power generation efficiency decreases, it controls the autonomous driving cleaning vehicle 2 to automatically drive to a designated position according to the planned route. The robotic arm 3 is arranged on the autonomous driving cleaning vehicle 2. It can be understood that the designated position is the position of the solar photovoltaic panel with reduced power generation efficiency.

[0036] The identification module 4 and the cleaning module, the identification module 4 and the cleaning module are both arranged on the robotic arm 3, the identification module 4 is used to identify and mark the area of accumulated dust to be cleaned on the solar photovoltaic panel, and the cleaning module is used to clean the area of accumulated dust to be cleaned.

[0037] The communication module 5, the communication module 5 is used for the communication connection between the identification module 4, the cleaning module, the robotic arm 3 and the base station 1.

[0038] In the present invention, the system can autonomously identify the solar photovoltaic panels that need to be cleaned and automatically navigate to the target location for cleaning, reducing the need for manual intervention, saving a lot of manpower and greatly improving the cleaning efficiency. The robot arm 3 and the cleaning module and identification module 4 arranged thereon can achieve precise cleaning of the solar photovoltaic panels, ensuring accurate judgment of the dust accumulation and cleaning effect.

[0039] In some embodiments, the identification module 4 includes a high-definition camera, which collects image information on the solar photovoltaic panel. The base station 1 performs identification based on the image information. If it is identified that the solar photovoltaic panel is dusty, the coordinates of the solar photovoltaic panel are marked and movement instructions and cleaning instructions are issued.

[0040] The robot arm 3 moves to the marked coordinates according to the moving instruction, and the cleaning module cleans the dust accumulation area at the marked position according to the cleaning instruction.

[0041] In the present invention, a high-definition camera is used to obtain image information of the surface of the solar photovoltaic panel, which can accurately detect the dust accumulation and provide higher accuracy and reliability. The base station 1 can mark the specific location coordinates of the dust accumulation area that needs to be cleaned based on the image information provided by the high-definition camera. This cleaning strategy avoids unnecessary waste of resources and only starts the cleaning program when necessary, thereby improving overall efficiency. From identification and positioning to the execution of the cleaning task, the entire process does not require human intervention. The robotic arm 3 can automatically navigate to the specified coordinates according to the received movement instructions, and the cleaning module starts the cleaning work according to the cleaning instructions, which greatly simplifies the operation process.

[0042] In some embodiments, the robotic arm 3 includes a robotic arm base 31 disposed on the autonomous driving cleaning vehicle 2 , a multi-stage motion joint 32 connected to the robotic arm base 31 , and a motion module 33 for driving the multi-stage motion joint 32 to move.

[0043] In some embodiments, the multi-stage motion joint 32 includes a primary robotic arm 321 connected to the robotic arm base 31 , and a secondary robotic arm 322 connected to the end of the primary robotic arm 321 .

[0044] In some embodiments, the motion module 33 includes a first universal device 331 that is transmission-connected between the manipulator base 31 and the primary robotic arm 321, a second universal device 332 that is transmission-connected between the end of the primary robotic arm 321 and the secondary robotic arm 322, and a third universal device 333 that is arranged at the end of the secondary robotic arm 322.

[0045] In the present invention, the design of the multi-stage motion joint 32 and the universal device enables the robotic arm 3 to have extremely high flexibility. Through the coordinated operation of the first, second, and third universal devices, the first- and second-stage robotic arms can move freely in three-dimensional space, achieving precise access to and operation on any position on the surface of the solar photovoltaic panel. This design is particularly suitable for handling photovoltaic panel cleaning tasks at different angles and positions. The combination of the first- and second-stage robotic arms extends the overall length and operating range of the robotic arm, enabling it to cover a larger area of the photovoltaic panel surface. At the same time, the third universal device 333 is located at the very end, ensuring that the recognition module 4 and the cleaning module can contact the photovoltaic panel at the best angle and distance, improving the cleaning effect.

[0046] In some embodiments, the cleaning module includes a blowing cleaning unit 6 and a high-pressure water cleaning unit 7, and both the blowing cleaning unit 6 and the high-pressure water cleaning unit 7 are arranged on the third universal device 333.

[0047] In some embodiments, the high-pressure water cleaning unit 7 includes a water tank 71 arranged on the autonomous cleaning vehicle 2, a high-pressure nozzle 72 arranged on the third universal device 333, a water pipe 73 connecting the water tank 71 and the high-pressure nozzle 72, and a first pumping device (not shown in the figure) arranged in the water tank 71. The first pumping device is used to pump high-pressure water flow to the high-pressure nozzle 72. Specifically, the first pumping device pumps high-pressure water flow to the high-pressure nozzle 72 according to the control of the cleaning instruction.

[0048] In the present invention, the high-pressure nozzle 72 is used in combination with the first pumping device to generate high-pressure water flow, which can effectively remove dust and stains on the surface of the solar photovoltaic panel. Compared with traditional manual cleaning or low-pressure flushing methods, the high-pressure water flow can more thoroughly remove stubborn stains, ensuring the cleanliness of the photovoltaic panel surface, thereby improving the photoelectric conversion efficiency.

[0049] By precisely controlling the working state of the first pumping device, the pressure and flow rate of the water flow can be adjusted according to actual needs, avoiding unnecessary waste of water resources. This precise control not only improves the cleaning efficiency but also reduces the impact on the environment. Arranging the high-pressure nozzle 72 on the robotic arm 3 enables the cleaning head to move flexibly and accurately reach any position that needs to be cleaned. Whether it is a horizontally installed or a photovoltaic panel with a large inclination angle, it can be effectively cleaned, greatly enhancing the applicability and flexibility of the system.

[0050] In some embodiments, the air blowing and cleaning unit 6 includes an air compressor 61 disposed on the autonomous cleaning vehicle 2, an air nozzle 62 disposed on the third universal device 333, an air pipe 63 connecting the air compressor 61 and the air nozzle 62, and a second pumping device (not shown in the figure) disposed on the air compressor 61. The second pumping device is configured to pump high-pressure air flow to the air nozzle 62. Specifically, the second pumping device pumps high-pressure air flow to the air nozzle 62 according to the control of the cleaning instruction.

[0051] In the present invention, in addition to high-pressure water flow cleaning, the newly added air nozzle 62 and high-pressure air flow provide a non-contact cleaning method. This dual-mode cleaning mechanism of the present invention can flexibly select the most suitable cleaning method according to the specific situation of dust accumulation, which can not only effectively remove light dust but also cope with relatively stubborn stains. Using high-pressure air flow for preliminary or comprehensive cleaning, especially for some vulnerable or photovoltaic panels with thin surface coatings, can reduce the risk of scratches or other physical damages caused by direct contact and extend the service life of the photovoltaic panels.

[0052] In some embodiments, the autonomous cleaning vehicle 2 includes a tracked autonomous cleaning vehicle 2.

[0053] In the present invention, the tracked design has a better ground contact area and traction force compared with wheeled vehicles, and can stably travel on terrains such as uneven, muddy, sandy or obstacle-ridden terrains. This enables the autonomous cleaning vehicle 2 to operate efficiently in various complex outdoor environments, including grasslands, muddy lands, gravel grounds, etc., improving the applicability and reliability of the system.

[0054] In some embodiments, the manipulator base is rotatably disposed 360° on the autonomous cleaning vehicle 2.

[0055] In some embodiments, the system further includes a battery (not shown in the figure), and the battery is disposed on the autonomous cleaning vehicle 2 and is respectively connected to the cleaning module, the recognition module 4, the motion module 33 and the communication module 5.

[0056] In the present invention, the battery provides power support for the entire system, enabling the autonomous cleaning vehicle 2 to operate independently without an external power source. This autonomous design is particularly important for solar power plants far from fixed power sources, ensuring that the cleaning operation can be carried out at any time and any place without being restricted by power supply. Due to no longer relying on cables or other external power supply facilities, battery power supply makes the autonomous cleaning vehicle 2 have higher flexibility and mobility.

[0057] In some embodiments, there are multiple high-pressure nozzles 72, and the multiple high-pressure nozzles 72 are arranged in an array on the third universal device 333.

[0058] In the present invention, the use of multiple high-pressure nozzles 72 can cover a larger cleaning area and reduce the time required for single cleaning. Compared with a single nozzle, the multi-nozzle design can clean different areas of the photovoltaic panel simultaneously, thus significantly improving the cleaning speed and efficiency.

[0059] The present invention mainly aims at the problem of dust accumulation cleaning on solar photovoltaic panels. When the solar photovoltaic panel is blocked by dust accumulation, the system controls the autonomous cleaning vehicle 2 to drive near the area to be cleaned through a program. The autonomous cleaning vehicle 2 is equipped with a robotic arm 3. The robotic arm 3 has a motion module 33, and a cleaning module and an identification module 4 are arranged on the robotic arm 3. The motion module 33 controls the movement of the robotic arm 3. The identification module 4 identifies the dust-accumulated area that needs to be cleaned, and the cleaning module completes the cleaning of the dust-accumulated area that needs to be cleaned through high-pressure blowing and high-pressure water washing, thereby realizing the automatic cleaning of dust on the solar photovoltaic panel.

[0060] In summary, the present invention realizes the automatic dust cleaning of the photovoltaic panel through the identification of dust accumulation on the photovoltaic panel and the control of automatic cleaning. By equipping the autonomous cleaning vehicle 2 with a robotic arm 3, and a universal device is provided in the robotic arm 3, which can achieve a dead-angle-free cleaning of the photovoltaic panel. The autonomous cleaning vehicle 2 carries an air compressor 61 and a water tank 71. The air compressor 61 provides compressed air, and the water tank 71 provides water source, without the need to provide from a remote end. The robotic arm is equipped with high-pressure nozzles 72 and air nozzles 62 to achieve effective cleaning of the photovoltaic panel.

[0061] Furthermore, the identification module 4 judges whether the position of the photovoltaic panel needs to be cleaned according to the color of the photovoltaic panel. If it needs to be cleaned, its coordinates and the dust-accumulated area are marked and cleaned. After the cleaning is completed, a recheck is carried out again. Among them, by analyzing the picture information collected by the analysis and identification module 4, if there is dust in the picture, there will be a color difference, and it is judged whether there is dust by analyzing the color difference.

[0062] In the present invention, the whole set of devices is powered by a battery and automatically charges when returning to the base station 1 after each task is completed, without energy consumption. The battery provides a power source for the high-pressure blowing device (including the air compressor 61, the air nozzle 62 and the air pipe 63) and the high-pressure water washing device (including the water tank 71, the high-pressure nozzle 72 and the water pipe 73).

[0063] In the present invention, the autonomous cleaning vehicle 2 adopts a crawler design and can rotate 360°, adapting to various road conditions.

[0064] A specific example provided by the present invention includes:

[0065] When the solar photovoltaic panel is covered by dust, resulting in a reduction in its power generation efficiency, the base station 1 triggers an automatic cleaning program and sends an automatic cleaning instruction. The autonomous cleaning vehicle 2 responds to the automatic cleaning instruction, departs from the base station 1, and automatically drives to the designated position according to the planned route. Then, the robotic arm 3 unfolds, activates the intelligent recognition mode, identifies and marks the dust accumulation area to be cleaned through the recognition module 4, and then the robotic arm 3 performs high-pressure water washing and high-pressure purging on the dust accumulation area. After purging, identification and photovoltaic panel power generation efficiency judgment are carried out again. If the cleaning is not thorough, the operation is repeated until the cleaning is completed.

[0066] After the cleaning is completed, the robotic arm 3 retracts and returns to the base station 1, where the water tank 71 is replenished and waits for the next cleaning.

[0067] In some embodiments, there are multiple air nozzles 62, and the multiple air nozzles 62 are arranged in an array on the robotic arm 3.
