The application belongs to the technical field of dustproof filtration, and discloses an intelligent dustproof device for a municipal foundation trench and a use method, wherein the intelligent dustproof device for the municipal foundation trench comprises a pair of side rails, a plurality of sliding blocks are slidably connected to the top of the pair of side rails, a driving steel wire is fixed to the sliding blocks on one side, a steel wire suspension cable is fixed to the middle of the sliding blocks on both sides, and the installation plate, rotating rod, extrusion rod and other structures are matched, so that the device can be unfolded into a triangular surface support in strong wind, support is provided on both sides of the dustproof mesh screen, the tearing resistance is good, the use durability of the dustproof mesh screen is effectively improved, and after unfolding, the adjacent two rotating rods can be connected by magnetic attraction sub-catches and magnetic attraction female catches. Thus, the two sides of the dustproof mesh screen form a mesh support, the continuous mesh surface clamps the dustproof mesh screen in the middle, effectively improves the wind resistance, and ensures the use continuity and durability of the dustproof mesh screen.
