Description

Technical Field

[0001] The utility model relates to the technical field of solar panel dust removal devices, in particular to a guide rail type solar panel automatic wind dust removal device. Background Art

[0002] As renewable energy technologies develop, the use of solar panels (both flat and tubular) is becoming more and more popular. The efficiency of solar panels depends largely on the cleanliness of their surfaces. Dust, dirt and other deposits block sunlight and reduce the solar panel's ability to absorb light, thereby reducing the efficiency of power generation and heat generation.

[0003] At present, 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, and it is even more difficult to clean solar panels installed in inaccessible places. Although fixed cleaning systems can automate the cleaning process, they are generally not suitable for mobile or temporarily installed solar panels, and the installation and maintenance costs are high. In addition, improper operation of the above two methods will also cause damage to the surface of the solar panel (tube). Therefore, it is necessary to develop a cleaning device that can effectively remove dust from solar panels and is automatic, easy to move and maintain. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, a guide rail type solar panel automatic wind dust removal device is proposed to solve the problems raised in the above background technology. The utility model can quickly remove dust from the solar panel.

[0005] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:

[0006] The automatic wind dust removal device for rail-type solar panels includes a guide rail and a guide rail trolley installed on the guide rail and sliding along the guide rail. The guide rail trolley includes a trolley frame and a trolley driving mechanism that drives 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 fan is installed on the slider. An air outlet is installed at the air outlet of the fan. An image acquisition module is installed on the air outlet. 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 fan.

[0007] As a further technical solution of the utility model: the lower end of the linear guide rail is connected to the 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, the outer ring of the rotating chuck is provided with a plurality of slots adapted to the angle pins, and the rotating base is mounted on the trolley frame by fixing bolts.

[0008] As a further technical solution of the utility model: the trolley frame includes a trolley vertical beam installed directly above the guide rail, two trolley vertical beams are provided, and a plurality of trolley cross beams are provided between the two trolley vertical beams.

[0009] As a further technical solution of the utility model: the trolley driving mechanism includes four guide wheels arranged at the four corners of the trolley frame, a stepper motor is arranged on the side of each guide wheel, and a transmission gear set is arranged between the stepper motor and the guide wheel for transmission.

[0010] As a further technical solution of the utility model: 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.

[0015] Beneficial effects of the utility model:

[0016] The utility model can be used to clean solar panels or solar tubes. A fan is set up to remove dust and clean by wind power, and wind power replaces water flow impact and mechanical cleaning, thereby reducing the damage to the surface of the solar panel (tube) during the dust removal process. Moreover, unlike mechanical cleaning, the strength is easy to adjust, and no mechanical wear is generated on the surface of the solar panel (tube), which is beneficial to the cleaning and maintenance of the solar panel (tube).

[0017] The image acquisition module and the Raspberry Pi built-in program can automatically collect images and analyze whether the solar panel (tube) needs dust removal. For surfaces that do not need dust removal, the fan will not be turned on to achieve energy saving and intelligent control effects. The solar panel (tube) array can be quickly and automatically dusted, and automation is achieved, which greatly improves the work efficiency compared to manual cleaning.

[0018] In view of 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 and the ground to meet the needs of different regions. The guide rail trolley moves along the guide rail, and the dust removal device walking route is fixed by laying the guide rail, and the forward running resistance of the guide rail trolley is reduced.

[0035] 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 dust on the solar panel and transmits the information to the Raspberry Pi 29. The Raspberry Pi 29 determines whether wind dust removal is needed. If necessary, the fan 16 is turned on and the linear guide 22 drives the fan 16 to move up and down, thereby expanding the working area. After the work in this area is completed, the Raspberry Pi 29 controls the stepper motor 8 to reach the next working area with a fixed step distance.

[0036] The image acquisition module 19 is installed on the modified vent 18 to collect dust information on the solar panel, pre-process the collected solar panel image information, perform data enhancement, and use LabelImg to annotate the category and position information of the dust image in the image to obtain a data set; the improved version of YOLOV7 based on ConvNext and Swin-transformer is used to train the data set, and detect the category and position information of the solar panel (tube); the trained improved YOLOV7 model is saved in torch script format, and the trained model is used to detect the dust on the solar panel (tube) to be identified; the trained model is integrated into the software system developed based on Qt, and the software is deployed to Raspberry Pi 29.

If necessary, 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 working area. After the work in this area is completed, the Raspberry Pi 2 controls the stepper motor 8 to reach the next working area with a fixed step distance. In view of the different angles of solar panels or solar tube arrays in different regions, the rotating chuck 23 and the angle pin 25 can cooperate to change and fix the angle between the linear guide 22 and the ground.

[0038] Specific implementation of the utility model:

[0039] First, charge the battery pack 30 with a voltage of 220V to make the battery pack 30 usable; adjust the angle between the linear guide 22 and the ground according to the angle between the solar panel (tube) array and the ground, first pull out the angle pin 25, rotate the rotating chuck 23, and after the angle of the linear guide 22 is adjusted to a suitable 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, and the angle of the linear guide 22 is fixed, so that the angle of the linear guide 22 is consistent with the angle between the solar panel (tube) array and the ground, and reaches a parallel state.

[0040] Then, the power button on the touch screen 11 is used to turn on the computer, and then the screen turns on and enters the human-computer interaction interface. The program will perform a self-check to confirm whether it is in a normal state. After entering the working state, the heat dissipation axial flow fan 32 works, the battery pack 30 supplies power to the entire system, and the inverter 31 converts the voltage into a working voltage; the linear guide 22 will drive the image acquisition module 19 from the bottom to the top according to the detection program, and in this process, a picture is collected at the bottom, middle, and top respectively and sent to the Raspberry Pi 29 via a 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, little, and much" and correspond to the three gear modes of the fan 16 "off, low power, and high power". At this time, the fan 16 reaches the top of the linear guide 22 along with the slider 17. After image recognition, the position of the guide trolley 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. The single work process can be summarized as the upward stroke is the image information collection work, and the downward stroke is the wind dust removal work.

[0041] 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, and the forward spacing is 1000mm, which is the effective dust removal width of the fan 16, and repeats the image acquisition and wind dust removal work, and repeats this process continuously to complete the automatic dust removal work of the solar panel (tube) array.
