Public sunshade capable of being automatically folded and unfolded according to temperature

Abstract

The invention relates to the technical field of new energy, and discloses a public sunshade capable of being automatically folded and unfolded according to temperature, which comprises a first shell body, wherein a base is fixedly mounted on the inner bottom wall of the first shell body, a bracket is slidably mounted on the inner side of the base, a first spring is fixedly mounted at the bottom part of the bracket, a fixed photovoltaic panel is fixedly installed at the top part of the support, a fixed shaft is fixedly installed on the inner bottom wall of the first shell body, a second shell body is fixedly installed on the outer side of the fixed shaft, and a rotating shell body is installed at the top part of the fixed shaft in a sliding mode. According to the public sunshade capable ofbeing automatically folded and unfolded according to the temperature, the protection and cleaning effects are achieved at the same time, the cleaning function can be automatically started when certaindust or rainfall and snowfall weather is accumulated, the protection function can be started in rainstorm or hail weather, a photovoltaic panel is prevented from being damaged all the time, the service life of the photovoltaic panel is prolonged, the utilization rate of solar energy by the photovoltaic panel is improved, and the advocation of national energy conservation and emission reduction ismet.

Description

technical field [0001] The invention relates to the technical field of public facilities, in particular to a public sunshade that can be retracted automatically according to temperature.

AI Technical Summary

Problems solved by technology

It solves the problem that the existing public parasols cannot be retracted automatically according to the temperature, and once the existing public parasols are wetted by rain and then dried again, the sunshade effect of the public parasols will be reduced, which is not conducive to the long-term use of public parasols At the same time, it will also affect people's mood. At the same time, public parasols are always open and are easily damaged by strong winds, resulting in a waste of resources.
