[0002] Solar photovoltaic modules are the core and most important part of the solar power generation system. Their function is to convert solar energy into electrical energy, or to store it in batteries, or to drive the load. The quality and cost of solar photovoltaic modules will directly determine the quality and cost of the entire power system; dust on the surface of photovoltaic modules seriously affects their power generation efficiency. my country's large-scale photovoltaic power stations are mainly concentrated in the Gobi Desert area in the west, which is dry and water-scarce, and transportation is inconvenient. Manual cleaning of photovoltaic modules is labor-intensive and costly. In addition, dust accumulation will cause hot spot effects and affect the life of the modules, so they need to be cleaned. The existing photovoltaic module cleaning device flushes the photovoltaic modules through the set water pump, which wastes water resources. At the same time, if the stains are not cleaned up after the water dries, it will refract and reflect sunlight and affect the power generation efficiency. At the same time, the installation and disassembly of the entire cleaning device when it needs to be replaced are more troublesome.

When the photovoltaic module needs to be cleaned, the motor is started, and through the action of the cleaning mechanism, the cleaning roller rotates on the surface of the photovoltaic module and makes reciprocating linear motion on the surface of the photovoltaic module, thereby achieving a cleaning effect.

The strip water tank 7 can be fixed to the corresponding upper end of the cleaning roller 5 through the strip bracket 6 so as to slide synchronously with the direction of the cleaning roller 5. The upper end surface of the strip bracket 6 is provided with a strip water tank 7 for cleaning the surface of the photovoltaic module 3.

A ball 13 is movably embedded in the bottom surface of the limit block 12, and the ball 13 is attached to the upper end surface of the strip limit plate 4.

[0029] The adjusting hinge driving seat 2 is arranged at the end center position of the fixing seat 1, and an adjusting servo motor 19 is provided on one side of the adjusting hinge driving seat 2, driving the rotating shaft of the adjusting servo motor 19 to extend through and extend to the inner side wall of the adjusting hinge driving seat 2 and be rotatably connected through the bearing seat. A hinge top seat 20 is fixed at the bottom center position of the photovoltaic component 3, and one end of the hinge top seat 20 extends to the interior of the adjusting hinge driving seat 2 and is fixedly connected with the rotating shaft of the adjusting servo motor 19, so that the inclination angle bar at one end of the photovoltaic component 3 can be adjusted, so that the cleaning roller 5 can slide toward the inclination angle end of the photovoltaic component 3 to perform cleaning work.

[0030] Specifically, when in use, when it is necessary to clean the photovoltaic module, the servo motor 19 is started and adjusted to drive the hinge top seat 20 to rotate at a tilt angle. Before that, water is filled into the water storage chamber 18 so as not to exceed the water inlet hole 17. Then, the hinge top seat 20 moves at a tilt angle to make the photovoltaic module 3 move at a tilt angle. After the photovoltaic module 3 moves at a certain tilt angle, the cleaning roller 5 uses the tilt angle of one end of the photovoltaic module 3 to mesh and rotate on the gear parts 9 at both ends on the gear condition 11. The meshing rotation of the gear part 11 drives the cleaning roller 5 to not only rotate, but also rotate through The limiting strip groove 10 slides toward one inclined end, and at the same time, the water in the water storage chamber 18 follows the inclination and flows to the water inlet hole 17 on the side block 14 in the strip water tank 7 and flows into the water inlet chamber, so that the water is sprayed out by the downpipe 16 to the front end of the cleaning roller 5 sliding toward one end to wet the dust on the photovoltaic component 3, and the cleaning roller 5 is used to clean the dust and stains, and after cleaning, the strip scraper 8 is used to scrape the sewage on the surface of the cleaned photovoltaic component 3, and the scraped sewage flows to the two ends of the strip scraper 8 and is discharged to the outside to achieve the cleaning of the photovoltaic component 3.

[0031] And by adjusting the rotation of the servo motor in the other direction, the inclination angle of one end of the photovoltaic component 3 is adjusted, so that the cleaning roller 5 rotates and moves to the other inclined end through the gear part 9 to clean the photovoltaic component, so that the reciprocating angle inclination of the two ends of the photovoltaic component 3 can make the cleaning roller 5 perform reciprocating cleaning work, and when the cleaning roller 5 rotates, the strip bracket 6 will not follow the angle adjustment due to the design of the bearing part. At the same time, the combination of the limit block 12 and the ball 13 can make the strip bracket 6 remain stable when sliding, and will not block the sunlight from irradiating the photovoltaic component to convert light energy into electrical energy.
