Fig. 1 to 3 are schematic structural diagrams of an urban canopy system with wind pressure resistance according to an embodiment of the present invention, where the urban canopy system with wind pressure resistance includes a truss 1, a curtain 2, a fixing assembly 3, and an overload releasing device 4. The curtain 2 comprises a first end 21 and a second end 22 which are oppositely arranged, the first end 21 is fixedly connected to the truss 1, and the second end 22 comprises a first tensioning part 121 and a second tensioning part 122 which are oppositely arranged. The curtain 2 is provided with a plurality of windproof holes 25, and the windproof holes 25 are arranged at equal intervals in the length extending direction of the curtain 2 and the width extending direction of the curtain 2. The fixing component 3 is fixedly arranged on the ground, and the fixing component 3 is fixedly connected with the first tensioning part 121. The overload release device 4 comprises a limiting sleeve 41 and a vertical shaft 42, wherein one end of the limiting sleeve 41 is provided with a containing cavity 411 with an upward opening, and the other end of the limiting sleeve 41 is fixedly arranged on the ground. One end of the vertical shaft 42 is fixedly connected with the second tensioning part 122, the other end of the vertical shaft 42 is slidably connected with the accommodating cavity 411, and the other end of the vertical shaft 42 can be slidably clamped in the accommodating cavity 411, so that the second tensioning part 122 is fixed relative to the ground; alternatively, the other end of the vertical shaft 42 can be slidably removed from the receiving cavity 411 to allow the second tensioning portion 122 to be removed from the ground.

In the embodiment, the urban canopy system with the wind pressure resistance function can be arranged outdoors, such as on the river side, the lake side or the square. When the curtain 2 is subjected to a strong wind pressure (i.e. the tension force applied to the second tensioning portion 122 is greater than the maximum tension force), the second tensioning portion 122 can drive the vertical shaft 42 to move upwards under the action of the tension force, so that the vertical shaft 42 is separated from the stop collar 41, the second tensioning portion 122 is separated from the ground and is in a state of drifting along with the wind, and the wind pressure applied to the curtain 2 is effectively reduced.
