Abstract: A cleaning system and a cleaning method configured for cleaning task of solar panels are provided. The cleaning system includes an operation region, cleaning robots, shuttle robots, and a data processing system. The cleaning method includes a first carrying step, a cleaning step, and a second carrying step.

Abstract: A control method for a cleaning system, comprising the following steps: first control step—controlling a transfer robot to move a cleaning robot to a cleaning area; cleaning control step—controlling the cleaning robot to perform a cleaning operation on a upper surface of the cleaning area; second control step—controlling a transfer robot to move the cleaning robot away from the cleaning area.

Abstract: An edge positioning apparatus for a solar panel cleaning robot, and a positioning method thereof. The solar panel cleaning robot comprises a car body (10) and an edge positioning apparatus, and the car body travels or is resident on at least one solar panel (200). The edge positioning apparatus comprises an image acquisition unit (13) and an image recognition and processing unit. The image acquisition unit is arranged on the car body and is used for acquiring surface image information about the solar panel on a walking line of the car body. The image recognition and processing unit is used for processing image information, and in turn judging whether the car body is walking at an edge area of the solar panel.

Abstract: An objective of the present invention is to provide a method for determining and controlling a robot to move straightly on a sloping plane to solve a technical issue that a deviation of a conventional robot from a predetermined straight path is difficult to detect when the robot moves on a sloping plane and cannot be corrected, and moving on the straight path is difficult to guarantee.

Abstract: A solar panel cleaning robot is provided and has a robot body. The robot body can move on at least one solar panel. A cleaning device, a power system, a control system and an electric power system are disposed on an internal or an external of the robot body.

Abstract: A fault detection and positioning system for a cell panel in a large-scale photovoltaic array, includes a first photovoltaic panel fault detection and positioning system, a second photovoltaic panel fault detection and positioning system, and/or a third photovoltaic panel fault detection and positioning system. The detection and positioning system can detect faults of panels in the photovoltaic array in real time, especially accurately positioning a photovoltaic panel in which a fault occurs; the number of sensors can be minimized, so that the detection costs can be reduced; and the system can be easily implemented and mounted in existing power stations.

Abstract: A track tension device and a track moving device are provided. The track tension device includes an upper transmission belt, a lower transmission belt, an upper tension portion, a lower compression portion and a resilient support portion. The track moving device includes the track tension device.

Abstract: A liquid dispensing container and cleaning robot are provided. The cleaning robot includes the liquid dispensing container, the liquid dispensing container includes a column-shaped portion; a taper portion having a bottom surface connected to a lower bottom surface of the column-shaped portion; and a drainage outlet disposed on a top point of the taper portion; wherein the liquid dispensing container is disposed on a sloping plane; an included angle between a side surface of the taper portion and the bottom surface of the taper portion is greater than or equal to an included angle between a sloping plane and a level surface.
