Foldable device for solar panel

Abstract

The invention discloses a foldable device for a solar panel. A limiting device comprises a hinge rod; one end of the hinge rod is hinged onto the side wall of a first electric expansion rod; furthermore, the other end of the hinge rod is hinged onto the upper end face of a movable column; the movable column is movably inserted in a base; furthermore, the lower end of the movable column movably passes through an L-shaped plate; a screw moves, so that a resistance plate is contacted with a second electric expansion rod; a clamping groove continuously moves, so that the resistance plate drives asteel rope to move; therefore, a clamping rod rotates, so that the current position of the second electric expansion rod is in clamped connection; the effect of changing the angle is achieved; and thus, the device has the contractile effect, and also has the effect of adjusting the angle of the solar panel.

Description

technical field [0001] The invention relates to the technical field of solar panels, in particular to a foldable device for solar panels. Background technique [0002] Solar cells, also known as "solar chips" or "photovoltaic cells", are photoelectric semiconductor sheets that use sunlight to generate electricity directly. A single solar cell cannot be directly used as a power source. As a power supply, several single solar cells must be connected in series and parallel and tightly packed into components. [0003] A solar panel (also called a solar cell module) is an assembly of multiple solar cells, which is the core part of a solar power generation system and the most important part of a solar power generation system. Sunlight shines on the semiconductor p-n junction to form new hole-electron pairs. Under the action of the p-n junction electric field, the holes flow from the p-region to the n-region, and the electrons flow from the n-region to the p-region. After the cir...

[0007] The patent application with publication number CN106656012A discloses a solar panel cleaning device, which consists of the following structures: column, solar panel, guide rail, linear motor, brush holder, cleaning brush, battery, bracket, controller, Water tank, filter screen, water outlet main pipe, water outlet pipe, pneumatic control valve, water baffle, this cleaning device can clean the surface of the solar panel, but due to the simple structure of the solar panel fixing device, the angle of the solar panel cannot be adjusted , and can not be contracted to save space. In order to save space and better adjust the angle, we propose a foldable device for solar panels
