Problems solved by technology

Although there are some designs of folding and unfolding mechanisms for photovoltaic modules, these designs are often designed for photovoltaic modules of a certain shape and size, and have poor adaptability to photovoltaic modules with different aspect ratios and installation spaces, so they often need to match certain This type of photovoltaic module is difficult to promote and has low civilian value

Embodiment

[0032] Such as figure 1 As shown, the present invention provides a double-layer screw-guided photovoltaic mechanism folding and unfolding device that can be tracked. The device mainly includes a pitch angle adjustment device, a horizontal angle adjustment device, and a solar panel group opening and closing device.

[0033] The actuator of the horizontal angle adjustment device is a servo deceleration motor, and the rotation of the motor is controlled by a controller, which controls the direction and angle of the motor according to the signal input by the photoelectric sensor;

[0034] The pitch angle adjustment device uses a stepping deceleration motor, and the rotation of the motor is controlled by a controller. The controller controls the direction and angle of rotation of the motor according to the signal input by the photoelectric sensor.

[0035] Such as image 3 As shown, the core base 9 mainly includes opening and closing control motor mounts 12 arranged at both ends o...

Abstract

The invention relates to a light-following double-layer lead screw guide type photovoltaic mechanism folding and unfolding device which comprises a pitching angle adjusting device, a horizontal angleadjusting device and a solar panel group opening and closing device, and the pitching angle adjusting device is fixed on the horizontal angle adjusting device; and the horizontal angle adjusting device drives the solar panel set opening and closing device to rotate to achieve adjustment of the horizontal angle. Compared with the prior art, the device has the advantages of being high in structuralstrength, free of action interference, convenient to disassemble and assemble, suitable for various terrain environments and the like.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a folding and unfolding device for a light-tracking double-layer screw-guided photovoltaic mechanism. Background technique [0002] Most of the existing photovoltaic modules have a large area and have been 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 for maintenance and difficult to operate. [0003] 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 weather,...
