A photovoltaic array cleaning vehicle and a photovoltaic array cleaning method thereof

Abstract

The invention discloses a photovoltaic array washing vehicle. The photovoltaic array washing vehicle comprises a proceeding chassis, a washing head supporting and positioning unit, a washing head unit, a water supply unit, an operation control unit and a vehicle body pose information collection device used for obtaining pose information of a vehicle body relative to the photovoltaic array, wherein a motion control component of a proceeding chassis steering system driving part is controlled by a main control module of the operation control unit; the washing head supporting and positioning unit comprises a movable base located at the head of the vehicle and a working arm set mounted on the movable base; the movable base comprises a rotation device and a transverse moving device; the working arm group comprises a main arm and an end arm capable of respectively pitching; the washing head unit comprises a washing brush, a water spraying part and a distance measuring sensor used for measuring the surface position and pose of a photovoltaic array board relative to the washing head unit; the main control module of the operation control unit takes a computer as the core of control. The invention also provides a method for washing the photovoltaic array by using the washing vehicle. The washing process is intelligent, efficient, flexible and safe, and is simple to operate, excellent in washing effect and low in usage cost.

Description

technical field

[0001] The invention relates to a photovoltaic array cleaning vehicle and a photovoltaic array cleaning method thereof, in particular to a cleaning vehicle used for photovoltaic array cleaning in large-scale ground photovoltaic power plants and a corresponding photovoltaic array cleaning method. 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 panels will be covered with sand and dust within 1 to 2 weeks, seriously affecting their photoelectric conversion efficiency and even damaging the panels. Therefore, regular or timely cleaning of solar panels has become an essential part of the daily operation and maintenance of photovoltaic power plants.
