Embodiment 1
[0016] like figure 1 As shown, the photovoltaic power station cleaning system of this embodiment includes a frame 1 for installing panel glass, a motor 2 and a pulley 3 are installed on the frame 1, and a steel wire 4 driven by the motor 2 is movable on the pulley 3. 4 is fixed with cleaner 5. Wherein, the motor 2 is installed in the middle of the frame 1, and there are two cleaners 5, which are respectively located on both sides of the motor 2.
[0017] The control unit of the motor 2 is provided with a timer and a rain sensor, and in this embodiment, a humidity sensitive resistor is used as the rain sensor.
[0018] like figure 2 As shown, the pulley 3 is provided with a hold-down device for pressing the steel wire 4, and the hold-down device is composed of a spring 6 and a hold-down wheel 7, wherein the hold-down wheel 7 is located between the spring 6 and the pulley 3, and the steel wire 4 is located between the pulley 3 and the pulley 7. Between the compression wheels...

The invention provides a cleaning system for a photovoltaic power station and a control method thereof. The cleaning system for the photovoltaic power station and the control method of the cleaning system are used for conducting all-weather full-automatic cleaning on panel glass and solve the problems that the electricity generating power is affected and the hot spot effect is generated due to the fact that the panel glass is covered by dust and sundries, thereby improving the electricity generating power of the photovoltaic power station and prolonging the service life of the photovoltaic power station. The cleaning system for the photovoltaic power station comprises a framework used for installing the panel glass, a motor and a pulley are installed on the framework, a steel wire which is driven by the motor is movably erected on the pulley and a cleaner is fixed to the steel wire. The control method of the cleaning system comprises the following steps that timing is conducted through a timer and a rain sensor is used for detecting whether rainfall exists or not; if rainfall does not exist in a preset time span, a control unit controls the cleaner to conduct cleaning; if rainfall exist in a preset time, the control unit enables timing to be stopped when rail falls and controls the cleaner to conduct cleaning; the control unit enables timing to be started again through the timer every time cleaning is completed.
Description
technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a cleaning system for a photovoltaic power station and a control method thereof. Background technique [0002] The life of a photovoltaic power station is 20-30 years. The panel glass is exposed to the air for a long time. Dust attached to the glass will seriously affect the light transmission, and even form a hot spot effect, eventually destroying the entire component. The current photovoltaic power station does not have special cleaning equipment, and its panel glass is cleaned by rainwater. In areas with heavy sandstorms and little rain, the cleanliness of the panels cannot be guaranteed, so it is difficult to guarantee the power generation efficiency and service life of the photovoltaic power station. Contents of the invention [0003] The purpose of the present invention is to propose a cleaning system and control method for a photovoltaic powe...
