Device for supporting and positioning of cleaning terminal of photovoltaic array cleaning vehicle

Abstract

A device for supporting and positioning of a cleaning terminal of a photovoltaic array cleaning vehicle comprises a working arm set and a movable base. The movable base comprises a slewing device and a horizontal moving device, and is installed on a device bottom rack. The working arm set is installed on the movable base and includes an arm set base, a main arm, an end arm with execution terminal installation interface, an adapter rocker assembly, a push-pull rod, a main arm pitching hydraulic cylinder and an end arm posture-alignment hydraulic cylinder, wherein the root of the main arm is hinged to the arm set base; the main arm pitching hydraulic cylinder is hinged between the main arm and the arm set base; the end arm is hinged to one end of the main arm; the adapter rocker assembly is hinged to the position between the end and root of the main arm; the push-pull rod is hinged between the end arm and the adapter rocker assembly; the end arm posture-alignment hydraulic cylinder is hinged between the adapter rocker assembly and the arm set base. The device can meet the demand for cleaning any side of the vehicle, the structure is simple, the interface is distinct, the degree of automation is set reasonably, and the device is neat in appearance, flexible to operate, convenient to control and high in adaptability.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a device for performing terminal support positioning, in particular to a device that can be used for cleaning terminal support positioning of a photovoltaic array cleaning vehicle. Background technique [0002] The solar panels of the photovoltaic power station are installed in the form of arrays in the open air, and the sand, dust, sundries and some corrosive substances in the atmosphere are easy to adhere to the surface. Especially in arid, windy and desertified areas with sparse vegetation, the solar panels will be covered with dust within 1 to 2 weeks, which will seriously affect their photoelectric conversion efficiency and even damage the panels. Cleaning has become an essential part of the daily operation and maintenance of photovoltaic power plants. [0003] Foreign countries, especially Italy and other European countries, realized the mechanized cleaning of solar pa...
