Hydraulic and self-adaptive cleaning equipment for photovoltaic module

Abstract

The invention discloses hydraulic and self-adaptive cleaning equipment for a photovoltaic module and solves the problem that a mechanism in the prior art cannot meet the requirement for fast cleaning of a photovoltaic module in a large-scale group photovoltaic plant. The hydraulic and self-adaptive cleaning equipment is mainly technically characterized by comprising two groups of cleaning assemblies mounted on a cleaning robot, wherein each cleaning assembly comprises a brush carrier assembly for cleaning the surface of a photovoltaic panel and a driving assembly for controlling posture adjustment of the brush carrier assembly, and the driving assembly comprises a lifting module for driving the brush carrier assembly to finish lifting motion in the vertical direction and a rotating module for driving the brush carrier assembly to rotate to adapt to the angle of the photovoltaic panel; a gantry assembly is further fixed on the cleaning robot, and an adjusting unit for horizontally driving the gantry assembly to get close to or far away from a photovoltaic panel assembly is arranged between the cleaning robot and the gantry assembly. The horizontal position of each cleaning assembly is adjusted by the adjusting unit added in the technical scheme, so that the requirement for efficient cleaning of the photovoltaic module in the large-scale group photovoltaic plant is met.

Description

technical field [0001] The invention relates to a cleaning device for photovoltaic power station components, in particular to a high-efficiency dust removal device for photovoltaic modules installed in groups in a large photovoltaic power station. Background technique [0002] As a green energy, solar energy is widely used in various fields due to its advantages of inexhaustibility, environmental protection and safety, and no geographical restrictions. In the practical application of solar photovoltaic power generation, photovoltaic modules are the most important unit of power generation, and their output power is directly affected by the intensity of sunlight. When sand, dust, and snow fall on the surface of photovoltaic modules, the light transmittance will be reduced, resulting in a significant decrease in photoelectric conversion efficiency. This problem is particularly serious in the central and western regions where wind and sand are relatively large. Therefore, in or...

Problems solved by technology

[0007] However, the brush holder assembly in the prior art 2 only has two degrees of freedom of lifting and turning angles in the space, so there is a big problem when cleaning the photovoltaic modules: it is necessary to control the position of the car to be close to the photovoltaic panels, and then Control the brush holder assembly to adjust the height and angle of the photovoltaic panel

However, photovoltaic modules are generally installed in places with harsh geological environments such as deserts and open fields. In such cases, in order to reduce the vibration of the cleaning robot, it is generally necessary to set the tread of the tires very wide to achieve vibration reduction. However, In this way, when adjusting the distance between the car and the photovoltaic panel, the cleaning robot becomes "bulky", especially when adjusting between two rows of photovoltaic panel components, it is very inconvenient

However, it is necessary to adjust the distance between the vehicle and the photovoltaic panel. This is because the brush holder assembly itself can only be lifted and rotated, and the rotation control is limited by the maximum stroke of the hydraulic cylinder. Therefore, the adjustment angle is generally It will not exceed 60 degrees, otherwise it will cause the overall size of the hydraulic cylinder to be too large and difficult to drive. However, when the vehicle distance is unreasonable, this angle may be difficult to adapt to the angle of the photovoltaic panel (the orientation of the photovoltaic panel is determined according to the angle of direct sunlight) to obtain the most solar energy), therefore, no matter the existing technology 1 or 2, it is difficult to meet the continuous and reliable cleaning requirements of the group photovoltaic panel components
