Intelligent photovoltaic array washing car

Abstract

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.

Description

Technical field [0001] The invention relates to a solar cell panel cleaning vehicle, in particular to an intelligent photovoltaic array cleaning vehicle used for surface cleaning of photovoltaic array components in large-scale ground photovoltaic power stations. Background technique [0002] The solar panels of the photovoltaic power station are installed in an open-air tilt in the form of an array, and the sand, dust, debris and some corrosive substances in the atmosphere are easily attached to the surface. Especially in arid, windy and sparsely vegetation desertified areas, the solar panels will be covered with sand and dust in 1 to 2 weeks, which will seriously affect the photoelectric conversion efficiency and even damage the solar panels. Therefore, the solar panels should be treated regularly or timely. Cleaning has become an essential and important link in the daily operation and maintenance of photovoltaic power plants. [0003] The cleaning of photovoltaic panels usually ...

Problems solved by technology

[0007] The various technical solutions and listed products related to the independent traveling photovoltaic array cleaning equipment above have their own characteristics, and they have different aspects in the effect, efficiency, cost, environmental adaptability, reliability, degree of automation and ease of operation of photovoltaic array cleaning operations. Most of them have their own corresponding improvements in different degrees, but this improvement is unilateral and partial, and the technical solution itself also has various deficiencies such as complex structure, insufficient practicability, or inconvenient operation, and the overall and In other words, the degree of intelligence of existing technical solutions is not ideal. Therefore, there is no intelligent automatic cleaning product for large-scale photovoltaic power plant solar panel arrays that can be used in the market.
