Technical Field

[0001] The present invention relates to the technical field of solar panel dust removal devices, and particularly to a rail-type automatic wind dust removal device for solar panels. Background Art

[0002] With the development of renewable energy technologies, the use of solar panels (including flat and tubular) has become increasingly popular. The efficiency of solar panels depends to a large extent on the cleanliness of their surfaces. Dust, dirt, and other deposits can block sunlight, reducing the light absorption capacity of solar panels, thereby decreasing power generation and heat generation efficiency.

[0003] Currently, the cleaning of solar panels mainly relies on manual cleaning or the use of fixed cleaning systems. Manual cleaning is time-consuming, labor-intensive, and costly. Moreover, for solar panels installed in hard-to-reach places, the cleaning work is even more difficult. Fixed cleaning systems can automate the cleaning process, but they are usually not suitable for mobile or temporarily installed solar panels, and the installation and maintenance costs are high. And improper operation of the above two methods can also cause damage to the surface of solar panels (tubes). Therefore, it is necessary to develop a cleaning device that can effectively remove dust from solar panels and is also automatic, easy to move, and maintain. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, a rail-type automatic wind dust removal device for solar panels is proposed to solve the problems raised in the above background art. The present invention can quickly remove dust from solar panels.

[0005] In order to achieve the above object, the present invention is implemented by the following technical solutions: A rail-type automatic wind dust removal device for solar panels includes a rail and a rail trolley installed on the rail and sliding along the rail. The rail trolley includes a trolley frame and a trolley driving mechanism for driving the trolley frame forward. An angle-adjustable linear guide is installed on the trolley frame. A slider is slidably installed on the linear guide. The slider is driven by a servo motor. A blower is installed on the slider. An air outlet of the blower is provided with an air outlet modification, and an image acquisition module is installed on the air outlet modification. A control module and a power supply module are also provided on the trolley frame. The control module is electrically connected to the image acquisition module, the trolley driving mechanism, the servo motor, and the blower.

[0006] As a further technical solution of the present invention: The lower end of the linear guide is connected to an extension rod. The lower end of the extension rod is a circular rotating chuck. The inner ring of the rotating chuck is rotatably connected to a rotating base. A detachable angle pin is provided on the rotating base. A plurality of slots adapted to the angle pin are provided on the outer ring of the rotating chuck. The rotating base is installed on the trolley frame through a fixing bolt.

[0007] As a further technical solution of the present invention: The trolley frame includes trolley vertical beams installed directly above the guide rails. There are two trolley vertical beams, and multiple trolley cross beams are arranged between the two trolley vertical beams.

[0008] As a further technical solution of the present invention: The trolley driving mechanism includes four track wheels arranged at the four corners of the trolley frame. A stepping motor is arranged on the side of each track wheel, and a transmission gear set for transmission is arranged between the stepping motor and the guide rail wheel.

[0009] As a further technical solution of the present invention: The control module includes a Raspberry Pi and a touch screen installed on the trolley frame, and the Raspberry Pi and the touch screen are electrically connected.

[0010] As a further technical solution of the present invention: The power supply module includes a battery pack and an inverter. The battery pack and the inverter are electrically connected, and the battery pack and the inverter are installed on a flat plate fixed on the trolley frame.

[0013] As a further technical solution of the present invention: The guide rail is installed on the ground through a guide rail fixing plate.

[0014] Advantages of the present invention: The present invention can be used to clean solar panels or solar tubes. By setting up a fan to perform dust removal and cleaning through wind power, replacing water flow impact and mechanical cleaning with wind power, reducing surface damage to the solar panels (tubes) during the dust removal process. Moreover, different from mechanical cleaning, its intensity is easy to adjust, and it does not cause mechanical wear to the surface of the solar panels (tubes), which is beneficial to the cleaning and maintenance of the solar panels (tubes).

[0015] Through the image acquisition module and the built-in program of the Raspberry Pi, it can automatically collect images and analyze whether the solar panels (tubes) need dust removal. For surfaces that do not require dust removal, the fan is not turned on, thus achieving the effects of energy saving and intelligent control. It can quickly and automatically remove dust from the solar panel (tube) array and realizes automation, greatly improving the operation efficiency compared with manual cleaning.

[0016] Aiming at the different angles of solar panels or solar tube arrays in different regions, a rotating chuck and an angle pin are set to cooperate with each other to adjust the angle between the linear guide rail and the ground to meet the needs of different regions.

[0022] A linearly adjustable guide rail 22 with adjustable angle is installed on the trolley frame. A slider 17 is slidably installed on the linearly adjustable guide rail 22. The slider 17 is driven by a servo motor 14. A blower 16 is installed on the slider 17. An air duct adapter 18 is installed at the air outlet of the blower 16. An image acquisition module 19 is installed on the air duct adapter 18. The linearly adjustable guide rail 22 adopts an ACH12 linear guide rail with an effective stroke of 1050 mm. The servo motor 14 HG-KR13 has a working voltage of 220 V. The blower 16 is an EK125M blower with a maximum speed of 2510 revolutions per minute and a power of 95 W. The shape of the air duct adapter 18 is flat.

[0023] The lower end of the linearly adjustable guide rail 22 is connected to an extension rod 13. The lower end of the extension rod 13 is a circular rotating chuck 23. The inner ring of the rotating chuck 23 is rotatably connected to a rotating base 24. A detachable angle pin 25 is arranged on the rotating base 24. A plurality of card slots adapted to the angle pin 25 are formed on the outer ring of the rotating chuck 23. The rotating base 24 is installed on the trolley cross beam 6 through a fixing bolt 26. For different angles of the solar panel array in different regions, the included angle between the linearly adjustable guide rail 22 and the ground can be adjusted. First, pull out the angle pin 25, rotate the rotating chuck 23. After the angle of the linearly adjustable guide rail 22 is adjusted to the appropriate position, insert the angle pin 25 into the rotating base 24, and the angle pin 25 is snapped into the card slot of the rotating chuck 23, and the angle of the linearly adjustable guide rail 22 is fixed.

[0024] A control module and a power supply module are also arranged on the trolley frame. A flat plate 9 is fixed on the trolley cross beam 6. The control module and the power supply module are installed on the flat plate 9. The control module includes a Raspberry Pi 29 and a touch screen 11. The Raspberry Pi 29 and the touch screen 11 are electrically connected. A touch screen support 27 and a touch screen housing 28 are arranged outside the touch screen 11.

[0025] The power supply module includes a battery pack 30 and an inverter 31. The battery pack 30 and the inverter 31 are electrically connected. The battery pack and the inverter 31 are installed on the flat plate 9. The battery pack 30 provides energy for other electrical components, and the inverter 31 converts the voltage of the battery pack 30 into the working voltage.

The model of the inverter 31 is 24V1200W, and the output voltage is 220V.

[0026] A dust-proof cover 10 is provided on the trolley frame. The dust-proof cover 10 is a rectangular stainless steel box body, and the inside of the stainless steel box is sprayed with gray paint. The dust-proof cover 10 is installed on the flat plate 9. The control module and the power supply module are located inside the dust-proof cover 10, which plays a role in protection and dust prevention. The dust-proof cover 10 is also provided with openings for installing a cooling axial flow fan 32 and a ventilation grille 12. The cooling axial flow fan 32 can discharge the heat inside the dust-proof cover 10 to protect the components.

[0027] The Raspberry Pi 29 is electrically connected to the image acquisition module 19, the stepper motor 8, the servo motor 14, and the fan 16. The image acquisition module 19 collects the dust condition on the solar panel and transmits the information to the Raspberry Pi 29. The Raspberry Pi 29 determines whether wind dust removal is required. If so, the fan 16 is turned on, and the linear guide 22 drives the fan 16 to move up and down, thereby expanding the operation area. After the operation in this area is completed, the Raspberry Pi 29 controls the stepper motor 8 to reach the next operation area with a fixed step distance.

[0028] The image acquisition module 19 is installed on the air outlet 18 to collect the dust information of the solar panel, preprocess and enhance the image information of the collected solar panel, and use LabelImg to label the category and position information of the dust image in the image to obtain a data set. An improved YOLOV7 based on ConvNext and Swin-transformer is used to train the data set, and the dust category and position information of the solar panel (tube) are detected. The trained improved YOLOV7 model is saved in the torch script format, and the trained model is used to detect the dust on the solar panel (tube) to be recognized. The trained model is integrated into a software system developed based on Qt, and the software is deployed to the Raspberry Pi 29.

[0029] The image acquisition module 19 acquires the dust condition on the solar panel and transmits the information to the Raspberry Pi 29. The Raspberry Pi 29 determines whether wind dust removal is required. If so, the fan 16 is turned on, and the servo motor 14 and the linear guide 22 drive the fan 16 to move up and down, thereby expanding the operation area. After the operation in this area is completed, the Raspberry Pi 29 controls the stepper motor 8 to reach the next operation area at a fixed step distance. For different angles of solar panels or solar tube arrays in different regions, the rotating chuck 23 and the angle pin 25 cooperate to change and fix the angle between the linear guide 22 and the ground.

[0030] Specific embodiments of the present invention: First, charge the battery pack 30 with a 220V voltage to make the battery pack 30 reach a usable state; according to the angle between the solar panel (tube) array and the ground, adjust the angle between the linear guide 22 and the ground. First, pull out the angle pin 25 and rotate the rotating chuck 23. After the angle of the linear guide 22 is adjusted to the appropriate position, insert the angle pin 25 into the rotating base 24, and the angle pin 25 is snapped into the slot of the rotating chuck 23, so that the angle of the linear guide 22 is fixed, making the angle of the linear guide 22 consistent with the angle between the solar panel (tube) array and the ground, reaching a parallel state.

[0031] Then, turn on the machine through the power-on button on the touch screen 11. Subsequently, the screen is turned on and enters the human-machine interaction interface. The program will perform a self-check to confirm whether it is in a normal state. After entering the working state, the cooling axial flow fan 32 works, the battery pack 30 supplies power to the entire system, and the inverter 31 converts the voltage into the working voltage; the linear guide 22 drives the image acquisition module 19 to move from the bottom to the top according to the detection program. During this process, a picture is taken at the bottom, middle, and top respectively and sent to the Raspberry Pi 29 through the data cable; after receiving the image information, the Raspberry Pi 29 will determine the dust images corresponding to the three parts according to the internal image recognition program and divide them into three dust levels: "none, less, more", corresponding to the three gear modes of the fan 16: "off, low power, high power". At this time, the fan 16 reaches the top of the linear guide 22 along with the slider 17. After the image recognition, the position of the guide rail trolley 15 remains unchanged. The Raspberry Pi 29 controls the servo motor 14 to drive the slider 17 and the fan 16 from top to bottom, and selects the three fan working modes of "off, low power, high power" according to the dust information levels at the three positions. When the fan 16 reaches the bottom of the linear guide 22, the dust removal work in this working area is completed. A single working process can be summarized as the upward stroke for image information acquisition work and the downward stroke for wind dust removal work.

[0032] Finally, after the dust removal work in this area is completed, the Raspberry Pi 29 controls the stepper motor 8 to drive the guide wheel 4 forward. The forward spacing is 1000 mm, which is the effective dust removal width of the fan 16. Then, the image acquisition and wind dust removal work are repeated. By repeating this process continuously, the automatic dust removal work for the solar panel (tube) array is completed.
