Automatic cleaning device according to surface fouling degree of solar module

Abstract

The invention discloses an automatic cleaning device according to the surface fouling degree of a solar module. The device comprises a dust detection device, a control system, a water supply system and a cleaning mechanism. The dust detection device is used for detecting dust and dirt on the surface of the photovoltaic module and sending a signal to the control system; the control system controlsthe water supply system and the cleaning mechanism to carry out cleaning; the cleaning mechanism comprises a reinforced cleaning mechanism; a cleaning roller circularly moves up and down along a rectangular annular rack; the tops of the moving assemblies are fixedly connected through a top support, a water spraying swing mechanism is installed on the top support, and a water sprayer is installed on the water spraying swing mechanism; and the cleaning roller presses the water spraying swing mechanism to drive the water sprayer to rotate when ascending. Concentrated scrubbing can be carried outon dirt which cannot be washed away, and the shielding effect on the photovoltaic module is reduced on the premise that the dirt is effectively removed.

Description

technical field [0001] The invention relates to an automatic cleaning device according to the degree of contamination on the surface of a solar module. Background technique [0002] Now clean energy can be provided through the photovoltaic system. The photovoltaic system mainly consists of three parts: photovoltaic modules (solar panels), controllers and inverters. The main components are composed of electronic components. Since the photovoltaic module must be exposed to the outside to receive sunlight, it is easy to affect the photoelectric conversion due to the cover of dust and dirt on the surface, so it must be cleaned according to the situation. Although some automatic cleaning devices can use optical sensors to detect the degree of dust and dirt on the surface of photovoltaic modules to trigger cleaning actions. However, most cleaning mechanisms use flushing or scrubbing. The flushing method is not effective for highly adhesive dirt, and scrubbing will block photovolt...

Problems solved by technology

However, most cleaning mechanisms use flushing or scrubbing. The flushing method is not effective for highly adhesive dirt, and scrubbing will block photovoltaic modules, so it is not suitable for frequent cleaning. Pollution effect is also limited for highly cohesive dirt
