Impact-proof flow guide device and rainwater flow guide method

Abstract

This invention discloses an anti-impact diversion device, comprising a horizontal pipe, a horizontal fixed structure, a horizontal diversion cone, an elastic component, a vertical pipe, a vertical diversion cone, and a vertical fixed structure. The diameter of the horizontal pipe gradually decreases on the outlet side. The horizontal fixed structure is installed on the horizontal pipe. The horizontal diversion cone is placed on the outlet side of the horizontal pipe. The horizontal diversion cone is connected to the horizontal fixed structure via the elastic component, and the bottom diameter of the horizontal diversion cone is larger than the top diameter of the outlet of the horizontal pipe. The vertical pipe is placed on the horizontal pipe and connected to it. The vertical diversion cone is placed on the outlet side of the vertical pipe and connected to the vertical pipe via the vertical fixed structure, and the vertical diversion cone is immovable. The bottom diameter of the vertical diversion cone is smaller than the inner diameter of the vertical pipe. This invention also discloses a rainwater diversion method. This invention can effectively reduce the impact of drainage outlets on the water environment and aquatic ecology.
