DETAILED DESCRIPTION

[0015] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0016] Combined with Figures 1 to 3 As shown, a solar panel surface cleaning device comprises a telescopic rod 1 and a cleaning head; the cleaning head comprises a brushing assembly, the brushing assembly is used for brushing the surface of the solar panel, and comprises a brush roller frame 2, a brush roller 3 vertically rotatably mounted on the brush roller frame 2, and a brushing motor 4 mounted on the brush roller frame 2 and drivingly connected to the brush roller 3; an auxiliary supporting mechanism, the auxiliary supporting mechanism is used for auxiliary supporting the brushing assembly so that the relative height position of the brush roller 3 from the surface of the solar panel remains stable, and comprises an auxiliary bracket 5, and also comprises a plurality of rollers 6 arranged at the lower end of the auxiliary bracket 5; the brushing assembly is arranged inside the auxiliary bracket 5, and the front end of the telescopic rod 1 is hinged to the upper end of the auxiliary bracket 5; a flushing nozzle 12, and the flushing nozzle 12 has a plurality of them, which are divided into two groups and are respectively arranged at the front and rear ends of the auxiliary bracket 5.

[0017] The position of the brush assembly can be adjusted up and down, and the cleaning head also includes a brush roller height adjustment mechanism for adjusting the height position of the brush assembly, and the brush roller height adjustment mechanism includes two brush roller height adjustment units respectively arranged at the left and right ends of the auxiliary bracket 5. The brush roller height adjustment unit includes a slider 7, which is fixed to the side of the brush roller frame 2; a slide groove 8, which is arranged on the corresponding side of the auxiliary bracket 5 and slidably cooperates with the slider 7; a fixed seat 9, which has two fixed seats 9, which are respectively arranged at the upper and lower ends of the slide groove 8; a screw rod 10, which is rotatably mounted on the fixed seat 9 and threadedly cooperates with the slider 7; a knob 11, which is arranged at the upper end of the screw rod 10;

[0018] It should be noted that when adjusting the height of the brush assembly, the two knobs 11 are rotated synchronously and in the same direction. As the knobs 11 are rotated, the corresponding screw rods 10 rotate accordingly, and then the two sliders 7 move synchronously and in the same direction, thereby changing the height position of the brush assembly.

[0019] The cleaning device also includes a scraping mechanism fixed to the front end of the telescopic rod 1 for scraping the surface of the solar panel; the scraping mechanism includes a scraping frame 13 fixed at one end to the front end of the telescopic rod 1, and also includes a scraper 14 arranged at the other end of the scraping frame 13;

[0020] It should be noted that when scraping and washing is needed, the telescopic rod 1 is flipped upward counterclockwise. As the telescopic rod 1 rotates, the scraping and washing frame 13 is flipped downward counterclockwise until the scraper 14 abuts against the surface of the solar panel. At this time, the moving cleaning head can be used for scraping and washing.

[0021] The cleaning device also includes a switch box 15, on which a flushing switch and a brushing switch are provided; a mobile backpack 16, in which a liquid storage tank, a flushing pump, and a mobile power supply are provided; the telescopic rod 1 is hollow, and a connecting hole 17 is provided near the front end; the switch box 15 and the mobile backpack 16 are connected to the corresponding brushing motor 4 and the flushing nozzle 12 through the internal hollowness of the telescopic rod 1 and the connecting hole 17.

[0022] When cleaning,

[0023] The first step is to adjust the brushing assembly to a suitable height according to the dirtiness of the panel surface;

[0024] The second step is to move the cleaning head to the lower end of the surface of the solar panel to be cleaned, and turn on the flushing switch and the brushing switch, so that the flushing nozzle 12 and the brush roller 3 start working;

[0025] The third step is to slowly push the cleaning head upwards through the telescopic rod 1 until it reaches the upper end. During this period, attention should be paid to the angle of the telescopic rod 1 to prevent the scraper 14 from scraping the surface of the solar panel;

[0026] Step 4: Flip the telescopic rod 1 upward to adjust the angle so that the scraper 14 is against the surface of the solar panel, and then slowly move the cleaning head to the lower end. During this period, it is necessary to ensure that the scraper 14 is always against the surface of the solar panel for scraping and cleaning;

[0027] The fifth step is to determine whether the surface of the solar panel is clean. If not, repeat the second to fourth steps until the requirements are met.

[0028] The present utility model is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present utility model, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
