Description

Technical Field

[0001] The invention relates to the technical field of solar power generation, and in particular to a self-locking double-angle rotatable solar panel device. Background Art

[0002] Solar energy is an inexhaustible green energy. With the development of green and low-carbon economy, the country vigorously advocates the use of solar energy to generate electricity to increase the diversification of electricity and reduce environmental pollution. Traditional solar panel devices are installed on the ground through fixed brackets. They are generally fixed and cannot be adjusted as the sun rises and sets. The utilization rate of solar energy of such devices is extremely low.

[0003] To this end, the industry has begun to develop solar devices that can be rotated and adjusted. Most of them only support azimuth rotation adjustment and can be adjusted in azimuth, which improves the utilization rate of solar energy to a certain extent. However, it is generally impossible to fully adjust the azimuth and altitude angles, which effectively improves the utilization rate. In addition, the current adjustable solar devices cannot lock the angle after adjustment. Due to the influence of uncontrollable factors such as severe weather such as storms and wild animal activities, such rotatable solar panel devices will inevitably have angle deviations during service, thereby further reducing the utilization rate of solar energy. In addition, the general solar panel adjustment mechanism is an open setting. Since solar panels work in the wild all year round, they are easily eroded by rain and wind and sand.
