Wherein the body of the slow flow equipment, namely the slow flow filtering part, is placed towards the upstream surface, and the supporting rod extends out towards the backside surface. Therefore, the balance weight and the filter screen of the slow flow equipment can realize slow flow and filtration of flood.
Of course, the water surface of the river channel is wide or cannot be covered by a single slow flow unit. The slow flow units in this embodiment may be hinged, so that a plurality of slow flow units together form one slow flow device. The width of slow flow equipment has been increased, can carry out slow flow filtration to the flood in the river course of broad or the place of broad. Specifically, the upper cross beams and the lower cross beams of two adjacent slow flow units can be hinged to each other. And the directions of the other two buffer flow units hinged at the two ends of the same buffer flow unit are not consistent. That is, when the other slow flow unit hinged to the left side of the slow flow unit at the center position is rotatable toward the a surface of the slow flow unit at the center position, the other slow flow unit hinged to the right side of the slow flow unit at the center position is rotatable toward the B surface of the slow flow unit at the center position.
