Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a public sunshade that can be retracted automatically in a strong wind, which can be automatically retracted in a strong wind and released automatically when the wind stops, so as to prevent the public sunshade from being damaged by the impact of the strong wind. damage, reduce the waste of resources, and avoid damaging people's mood because the appearance and function of damaged public parasols will be affected. Automatic retraction in windy weather requires manual retraction, which is time-consuming and labor-intensive, and sometimes cannot be retracted in time, causing public parasols to be damaged by the impact of strong winds, resulting in waste of resources, and the cost of damaged public parasols Appearance and function will be affected, spoiling people's mood Disadvantages

Abstract

The invention relates to the technical field of new energy, and discloses a public sunshade capable of being automatically folded and unfolded in windy weather. The public sunshade comprises a supportcolumn, a shell is fixedly mounted at the top of the support column, a first rotating shaft is rotatably mounted on the inner bottom wall of the shell, and a shaft coupling is fixedly mounted at thetop of the first rotating shaft; and a second rotating shaft is fixedly installed at the top of the shaft coupling, a windmill is fixedly installed at the top of the second rotating shaft, a wire frame is fixedly installed on the outer side of the first rotating shaft, and a first permanent magnet is fixedly installed on the left wall in the shell. According to the public sunshade capable of beingautomatically folded and unfolded in the strong wind weather, the public sunshade can be automatically folded in the strong wind weather and can be automatically unfolded when the strong wind weatherstops, the public sunshade is prevented from being damaged by impact of strong wind, resource waste is reduced, and meanwhile the situation that the appearance and functions of the damaged public sunshade are affected, consequently the mood of people is damaged is avoided, meanwhile, the structure is simple, and a sensor and an external power supply are not needed.
