Embodiment Construction

[0021] Such as figure 1 with figure 2 As shown, an integrated system for automatically cleaning and sunshading the surface of a photovoltaic module includes a base 1 on which a bracket 2 is fixed, and a photovoltaic panel 3 is provided on the bracket 2. When installing the photovoltaic cell panel 3, in order to make the photovoltaic cell panel 3 better absorb sunlight, the photovoltaic cell panel 3 is generally placed obliquely, and the surface of the photovoltaic cell panel is preferably perpendicular to the incident sunlight. The present invention also includes a shading cloth 5 arranged above the photovoltaic cell panel, and an obstacle cleaning brush 6 is fixed at the front end of the shading cloth. A sunshade cloth retracting device is fixed on both sides of the photovoltaic cell panel, and the sunshade cloth is wound on the sunshade cloth retracting device. In this way, the sunshade cloth can be retracted and released by the sunshade cloth retracting device, because the ...

Abstract

The invention relates to a surface obstruction-removing and sun-shading device of a photovoltaic assembly, in particular to an automatic surface obstruction-removing and sunshading integrated device of the photovoltaic assembly. The automatic surface obstruction-removing and sunshading integrated device of the photovoltaic assembly comprises a base, wherein a support is fixed on the base; a photovoltaic cell panel is arranged on the support; sunshading cloth is arranged above the photovoltaic cell panel; an obstruction-removing brush is fixed at the front end of the sunshading cloth; sunshading cloth folding and unfolding devices are arranged on the two sides of the photovoltaic cell panel; and the sunshading cloth is wound on the sunshading cloth folding and unfolding devices. With adoption of the structure, removal of dust, ices and snows, bird droppings from the surface of the photovoltaic cell panel and other operations can be performed, and the dust, the snows, the ices and the like removed from the surface of the photovoltaic cell panel can fall onto the ground through an obstruction-discharging through hole or an obstruction-discharging slot; and when a photovoltaic system is abnormal (such as short circuit of the system, local heating and the like), a motor can unfold the sunshading cloth to shade sunlight and a direct current power supply can be disconnected safely.

Description

Technical field [0001] The invention relates to a device for cleaning and shading the surface of a photovoltaic module, in particular to an integrated device for automatically cleaning and shading the surface of a photovoltaic module. Background technique [0002] Solar photovoltaic power generation is a renewable green energy and a clean energy that is advocated worldwide. Solar photovoltaic power generation uses an array of photovoltaic modules, which is commonly referred to as solar panels, to convert solar energy into direct current for use, or to convert direct current to alternating current for use or to integrate into the power supply grid through an inverter. Solar photovoltaic modules are an indispensable part of photovoltaic systems. The normal operation of photovoltaic modules is directly related to the conversion efficiency of solar energy. [0003] Because solar photovoltaic modules need to be installed outdoors to receive sunlight, dust, snow, bird droppings, and ice...
