Description

Wind-proof device for curtain

Technical Field

The invention belongs to the field of municipal construction, and particularly relates to a wind-proof device for a curtain.

Background

Wind is a natural phenomenon caused by air flow, which is caused by solar radiant heat. Sunlight irradiates the earth surface to raise the earth surface temperature, and the air on the earth surface expands slightly and rises. After the hot air rises, low-temperature cold air flows in transversely, the rising air falls due to gradual cooling and weight change, the air is heated to rise due to high ground surface temperature, and wind is generated by the flowing of the air.

In daily life, the cloth-shaped objects are often blown off the surface of the covering in windy weather, or the cloth-shaped objects are wrinkled, so that the use of the original functions of the cloth-shaped objects such as projection curtains and sun-shading curtains for greenhouses is affected, and inconvenience is brought to production and life.

The wind vane is a device for measuring the direction of wind. A wind vane is basically an asymmetrically shaped object with a center of gravity point fixed to a vertical axis. When wind blows, the end which generates larger resistance to the air flow can rotate along the wind, and the wind direction is displayed.

The trapezoidal body is a three-dimensional figure with the upper surface and the lower surface parallel and all rectangular, and the four side surfaces are trapezoidal.

To this end, we propose a wind guard for a curtain to solve the above problems.
