Embodiment Construction

[0021] Such as figure 1 and figure 2 As shown, an integrated system for automatic obstacle removal and sunshade on the surface of photovoltaic modules includes a base 1 on which a support 2 is fixed, and a photovoltaic cell panel 3 is arranged on the support 2 . When installing the photovoltaic battery panel 3 , in order to make the photovoltaic battery panel 3 better absorb sunlight, the photovoltaic battery panel 3 is generally placed obliquely, and the surface of the photovoltaic battery panel is preferably perpendicular to the incident sunlight. The present invention also includes a sunshade cloth 5 arranged above the photovoltaic battery panel, and a brush 6 is fixed at the front end of the sunshade cloth. Sunshade fabric retractable devices are fixed on both sides of the photovoltaic cell panel, and the sunshade fabric is wound on the sunshade fabric retractable device. In this way, the sunshade cloth can be retracted and released by the sunshade cloth retracting devi...

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 clearing obstacles and shading the surface of a photovoltaic module, in particular to an integrated device for automatically removing obstacles and shading the surface of a photovoltaic module. Background technique [0002] Solar photovoltaic power generation is a kind of renewable green energy, and it is a clean energy that is being advocated all over the world. Solar photovoltaic power generation is to convert solar energy into direct current through a photovoltaic module array, which is often referred to as a solar panel, or convert direct current into alternating current through an inverter or incorporate it into the power grid. Solar photovoltaic modules are an essential part of photovoltaic systems, and 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, it...
