Definitions
- the invention relates to the field of cleaning robots, and in particular to a solar panel cleaning robot.
- a solar panel is a device that converts solar energy directly into electrical energy using photovoltaics that occur under the illumination of semiconductor materials. Solar panels can generate electricity in places where there is sunlight, so solar panels are suitable for a variety of applications, from large power stations to small portable chargers.
- the working environment of solar panels can only be outdoor, and the biggest problem affecting their work is not the wind and rain, but the dust accumulated all the year round. Dust or other attachments on the solar panel may affect the transmittance of the panel and impede the photoelectric efficiency, which will seriously affect the efficiency of the panel directly acquiring sunlight, reduce the energy absorption and conversion efficiency of the panel, and reduce the power generation efficiency.
- the solar panel can only be manually and regularly cleaned up. Due to the large area of the solar panel and the large number of panels used by the large power station, the dust will accumulate repeatedly and need to be repeatedly cleaned; therefore, the labor cost is high. The cleaning efficiency is low and the cleaning effect is poor.
- the cleaning robot is insufficiently powered, cannot travel freely, and has poor cleaning effect; since the tilt angle of the solar panel is generally between 10 and 40 degrees, the existing cleaning robot cannot travel freely on the slope plane, even if it can barely travel, It will run out of power soon.
- the cleaning robot will slide off the solar panel; because the solar panel is relatively smooth, the existing cleaning robot has a relatively small weight and wheel friction coefficient, and the friction is relatively small, and it is difficult to travel, and it is easy to slip.
- the cleaning robot cannot travel according to the prescribed route, and the coverage area during travel is small, and it will fall from the edge of the solar panel; the existing cleaning robot is generally set to automatically turn to the obstacle, because there is no obstacle on the solar panel, automatically The cleaning robot that travels can only travel on a single path, and the coverage area during the travel is small, which is inevitable. Will fall from the edge of the solar panel. Even if the path is planned in advance, the existing cleaning robot is easily affected by gravity and panel attachment during traveling, and it is easy to deviate from the path, and it is difficult to ensure straight travel; and the cleaning robot itself cannot detect and cannot travel through the entire panel. Will leave a lot of space that can't be cleaned.

If the transmitting coils are evenly distributed, the preset power threshold is greater than or equal to the amount of power consumed by the cleaning robot during one-way operation between any two adjacent transmitting coils.
- the step S606) specifically includes the following steps: step S6061) acquiring the remaining capacity SOC value of the rechargeable battery in real time; and step S6062) setting the remaining capacity SOC value of the rechargeable battery 622 with a preset charging capacity.
- the threshold is compared; if the remaining capacity SOC value of the rechargeable battery 622 is greater than or equal to a preset charging capacity threshold (eg, 95% or 100%), it is determined that the cleaning robot is full and stops charging.
- the control system of the cleaning robot activates the power system and the cleaning device to control the cleaning robot to continue working.
- the advantage of this embodiment is that a charging panel is independently disposed on the same plane as the solar panel; even if a metal material exists on the solar panel, the receiving coil and the transmitting coil can be electromagnetically induced to be coupled. Achieve wireless charging of the robot.
- the entire charging process can be automatically controlled without the need to manually remove the cleaning robot from the solar panel, so that the cleaning robot can automatically run, automatically charge, and automatically power off the solar panel, which can realize automatic continuous operation, effectively reducing management and maintenance costs. .
