Folding and unfolding device for unfolding self-angle-forming double-layer lead screw guide type photovoltaic mechanism

Abstract

The invention relates to an unfolding self-angle-forming double-layer lead screw guide type photovoltaic mechanism folding and unfolding device, which comprises: an opening and closing assembly arranged on ground, which includes a door-shaped core base, door-shaped lateral bases that are arranged on the left side and the right side of the core base in parallel respectively, universal wheels that are fixed to the bottoms of the lateral bases, a double-layer lead screw driving structure which is installed on the core base, and connecting rod structures that are connected with the double-layer lead screw driving structure and the lateral bases on the two sides respectively to achieve opening and closing linkage; a folding assembly which comprises a solar panel set composed of a plurality of solar panels, an installation frame used for fixedly installing the solar panels and a folding guide structure with a set pitch angle, wherein the installation frame is connected with the opening and closing assembly through the folding guide structure. Compared with the prior art, the invention has the advantages of higher dimensional adaptability, self-forming of a certain pitch angle when beingunfolded, increase of the utilization rate of light energy and the like.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a folding and unfolding device for a self-expanding angled double-layer screw-guided photovoltaic mechanism. Background technique [0002] Most of the existing photovoltaic modules have a large area and are placed outdoors for a long time. The surface is easily covered by dust, snow and other urban pollutants, resulting in a decrease in power generation efficiency. Regular manual cleaning is required, which is inconvenient for maintenance and difficult to operate. At the same time, in bad weather without sunlight, or even in extreme climates, they are still placed outdoors and suffer natural wear and tear caused by the harsh environment in vain, resulting in a short service life. At present, the solar panel array cannot be stowed, and it occupies a large area and is subject to a large area of ​​wind. It will still be greatly damaged when fighting against extreme weath...

Problems solved by technology

[0002] Most of the existing photovoltaic modules have a large area and are placed outdoors for a long time. The surface is easily covered by dust, snow and other urban pollutants, resulting in a decrease in power generation power. Regular manual cleaning is required, which is inconvenient to maintain and difficult to operate.

At the same time, it is still placed outdoors in harsh weather without sunlight, or even in extreme climates, and suffers in vain from the natural wear and tear caused by the harsh environment, resulting in a short service life.

At present, the solar panel array cannot be stowed, and it occupies a large area, and the wind-responsive area is relatively large. It will still be greatly damaged when fighting against extreme weather, and it takes up a lot of space.

At the same time, there are also some designs of folding and unfolding mechanisms for photovoltaic modules. These designs are often designed for photovoltaic modules of a certain shape and size. A certain type of photovoltaic module is difficult to promote; there are also many folding and unfolding mechanisms for photovoltaic modules that cannot form an angle when unfolded. If they are installed on a plane, they will be flat when unfolded. You can only change the installation method or use a light-following device, and the civilian value is low
