Opposite-direction energy dissipation device for water drain pipe of small-diameter water conveying pipeline

The utility model discloses an opposite energy dissipation device for a water drain pipe of a small-diameter water delivery pipeline, and relates to the technical field of water supply pipeline equipment, in particular to the opposite energy dissipation device for the water drain pipe of the small-diameter water delivery pipeline, which comprises a first water drain pipe, the back face of the energy dissipation assembly is fixedly connected with a connecting assembly. According to the opposite energy dissipation device for the small-diameter water delivery pipeline water drain pipe, through the arrangement of the energy dissipation assembly and the addition of the arc energy dissipation pipe opposite energy dissipation structure at the tail end of the water outlet of the first water drain pipe, high-pressure water flow from the main pipe passes through the first water drain pipe and then is evenly distributed into the arc energy dissipation pipe through the flow distribution pipe; two high-pressure water flow
