Description

Cleaning robot

Technical Field

The utility model relates to a clean the robot field, in particular to clean robot.

Background

Under the condition that fossil fuels are gradually reduced, solar energy as a new renewable energy source becomes an important component of energy sources used by human beings, and the solar energy application technology is rapidly developed in all countries in the world in the last decade. The solar panel refers to a device for directly converting solar energy into electric energy by using a photovoltaic effect (photovoltaic) of a semiconductor material under a lighting condition. Since power generation is possible in a place where sunlight is present, solar panels are applied to various fields from large power stations to small portable chargers, and have been rapidly developed in recent years.

The working environment of the solar panel can only be outdoors, and the biggest problem affecting the work of the solar panel is dust accumulated all the year round. The solar panel is attached with dust or other attachments, can influence the luminousness of panel board, hinders photoelectric efficiency to can seriously influence the efficiency that the panel directly acquireed sunshine, reduce the energy absorption and the conversion efficiency of panel, reduce the generating efficiency. The solar panel of prior art can only rely on the manual work to accomplish the cleaning work regularly in use, because the panel that solar panel area is great, large-scale power station used simultaneously is more, and beautiful dust can be accumulated repeatedly, needs to wash repeatedly: therefore, the labor cost is very high, the cleaning efficiency is low, and the cleaning effect is poor. In many occasions, in order to improve the space utilization rate, the solar panels are all arranged at high positions by utilizing the supports, so that greater difficulty and risk are brought to cleaning work. Many users of solar panels have to choose not to clean them in order to reduce the cost of cleaning, and thus are forced to bear the power loss caused by dust. Thus, a new automatic cleaning device is needed to automatically clean the solar panel.

The cleaning robot in the prior art can only be generally applied to a horizontal ground and cannot be applied to a slope plane like a solar panel. Even if the existing cleaning robot can be used on a solar panel, the cleaning robot can cause the difficulty that sundries cannot be completely removed in time after being cleaned in the working environment of a slope plane, so that the sundries are accumulated, the sundries are stuck to wheels again, secondary pollution is caused, the cleaning effect on the cleaning robot is reduced, and the danger of sliding caused by reduction of the friction coefficient exists. The cleaning robot can repeatedly clean sundries in the working environment of the slope plane, so that a large amount of energy is repeatedly consumed, the electric quantity is quickly exhausted, the field operation cannot be continuously carried out for a long time, and the cleaning efficiency is seriously influenced due to the charging difficulty.

When the body of the cleaning robot turns, turns around, backs up or changes the inclined posture, particularly when the cleaning robot backs up, the cleaning device of the body easily re-sticks the accumulated impurities at the front end of the body to the wheels, which causes secondary pollution and reduces the cleaning effect of the cleaning robot.
