Description

Photovoltaic cleans folding arm that cleans robot with cleaning Technical Field The invention belongs to the technical field of cleaning of photovoltaic panels, and particularly relates to a cleaning folding arm for a photovoltaic cleaning robot. Background The photovoltaic panel is core equipment for converting solar energy into electric energy, has large price span and multiple application scenes, has economic benefit and ecological value, is usually composed of a plurality of photovoltaic panels arranged at intervals, and is extremely easy to accumulate pollutants such as dust, pollen, bird droppings, greasy dirt and the like when the surface of the photovoltaic panel is exposed in natural environment for a long time. These dirt can form "shading effect", seriously reduce the luminousness and the generating efficiency of photovoltaic board, even cause safety problems such as hot spot effect, traditional cleaning mode is like artifical clean inefficiency, with high costs and there is the potential safety hazard, the arm cleans and relies on complicated algorithm control arm gesture, it is high to topography roughness requirement, easily lead to the clamp plate risk because of vibrations or wind-force, generally use special cleaner when wasing the photovoltaic board, but wash the in-process and incomplete, chemistry residues can form the film at the face, on the contrary, influence the luminousness, traditional round brush can become very dirty in the cleaning process moreover, if self-cleaning ability is not enough, can smear local intractable dirt (such as the excrement bird) to whole face, cause "cross contamination", traditional cleaning robot generally walks on ground and utilizes the arm to clean the photovoltaic board simultaneously, also have the robot of direct along the photovoltaic board frame to clean effectively, but this kind of robot generally only can clean the photovoltaic board of specification, the suitability is relatively poor, and through the mode of gripping removal is carried out along the photovoltaic board, the very steady condition that the washing appears because of the vibrations or not leading to the occurrence in-process appears in the process of shaking.
