Embodiment 1

[0024] Such as Figure 1-3 As shown, a windproof device for curtains includes a top plate 1 and wind collecting shells 2 arranged on both sides below the top plate 1, the upper end of the wind collecting shell 2 is fixedly connected with a rotating shaft 3, and the upper end of the rotating shaft 3 runs through the top plate 1 and is fixedly connected with For the wind vane 4, it should be noted that the air collecting shell 2 is a trapezoidal body, and the pointer rod of the wind vane 4 is set close to the side of the trapezoidal body with a smaller area, and the side wall of the air collecting shell 2 with a smaller area is set There are openings, which can not only reduce the resistance of the wind collecting shell 2 to the wind, but also, under the action of the wind vane 4, can drive the wind collecting shell 2 to rotate to collect the wind, and the opposite sides of the two wind collecting shells 2 are provided with supports Column 5, the upper end of the support column ...

Embodiment 2

[0028] Such as Figure 4 As shown, in this embodiment, the upper end of the top plate 1 is provided with a trapezoidal groove 14, and the upper end of the exhaust pipe 13 communicates with the bottom of the trapezoidal groove 14.

[0029] When the wind with a faster flow velocity enters the trapezoidal groove 14 along the exhaust pipe 13, because the cross-sectional area of ​​the outlet of the trapezoidal groove 14 is greater than the cross-sectional area of ​​the entrance, the air velocity will be slowed down, and the pressure in the trapezoidal groove 14 will be increased. Under the action of external wind force, the air in the trapezoidal groove 14 will be "sucked" outward, so that the air can flow better in the flow pipe 11 and the adsorption effect of the adsorption port 12 can be improved.

Abstract

The present invention belongs to the field of municipal construction, and especially relates to an anti-wind device for a curtain. The anti-wind device for the curtain comprises a top plate and wind collection housings arranged at two side of the lower portion of the top plate, the upper end of each wind collection housing is fixedly connected with one rotation shaft, the upper end of each rotation shaft penetrates the top plate and is fixedly connected one wind indicator, one opposites sides of the two wind collection housings are respectively provided with support columns, the upper ends ofthe support columns are fixedly connected with the lower end of the top plate, the side walls of the support columns are fixedly connected with sealed tubes, the wind collection housings are internally fixedly provided with horn-shaped wind collection covers, the lower ends of the wind collection housings are provided with openings, rotation connectors are fixedly connected with the internal portions of the openings, the upper ends of the rotation connectors are fixedly connected with air outlets of the wind collection covers through first connection tubes, the lower ends of the rotation connectors are rotationally connected with second connection tubes, one ends, far away from the rotation connectors, of the second connection tubes communicate with the sealed tubes, and a latticed runnerpipe is fixedly connected between the two sealed tubes. The anti-wind device for a curtain can automatically detect a wind direction and can perform fixing on a curtain through adoption of wind energy, and is clean and environmental friendly in the whole process and energy-saving and efficient.

Description

technical field [0001] The invention belongs to the field of municipal construction, in particular to a windproof device for curtains. Background technique [0002] Wind is a natural phenomenon caused by the movement of air, which is caused by the radiant heat of the sun. The sun's rays irradiate the earth's surface, which makes the surface temperature rise, and the air on the earth's surface expands and becomes lighter due to heat, so it rises. After the hot air rises, the low-temperature cold air flows in laterally. The rising air gradually cools and becomes heavier and falls. The higher surface temperature heats the air to rise again. This air flow produces wind. [0003] In daily life, it is often encountered that strong winds will blow the cloth away from the surface of the covering, or cause the cloth to wrinkle, which will affect the use of the original functions of the cloth such as projection screens and blackout curtains for greenhouses. and inconvenience to life...
