The invention provides an intelligent photovoltaic array washing car used for washing
photovoltaic arrays of a large-scale ground
photovoltaic power station. A washing head supporting and locating unit and a
power unit are arranged on the head portion and the
tail portion of a crawler base respectively, a
water storage unit is arranged adjacent to the
power unit, and a washing head unit is provided with range finder sensors used for measuring the distance between the washing head unit and
solar cell panels; the washing head supporting and locating unit comprises a movable base capable of rotating and transversely moving and a working arm set provided with a main arm and an end arm, wherein the main arm and the end arm can
pitch respectively; a water pump of a
water supply unit is driven by a
hydraulic motor; a computer is used as a control kernel of a main control module of an operation
control unit; a pair of proportional directional valves of the
hydraulic control unit controls two base crawler traveling motors, and other directional valves are electromagnetic directional valves controlled by the main control module. According to the intelligent photovoltaic array washing car, the position and the posture of the washing head unit relative to photovoltaic array panels and the position and the posture of a car body relative to the
photovoltaic arrays can be automatically controlled, and the intelligent photovoltaic array washing car is intelligent, efficient, flexible in operation, high in adaptability, easy and convenient to operate, concise in structure and good in washing effect.
