Title:
VORTEX FLOW TYPE WATER SURFACE CONTROL DEVICE FOR DRAINAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/081685
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a control plate on a suitable position in a rain water discharge chamber. An inflow pipe (2), an intercepting pipe (3) and a discharge pipe (4) are connected to a rain water discharge chamber (10). A vortex flow type water surface control device for a drainage system is provided with: the rain water discharge chamber (10); and a control plate (6) which is arranged in front of an opening (3a) of the intercepting pipe (3) opening to the rain water discharge chamber (10). Assuming that D represents the inner diameter of the opening, X represents the projection length of the control plate (6) with respect to the opening (3a), and Y represents the distance between the control plate (6) and the opening (3a), D, X and Y satisfy: (1) 0.5D ≤ X ≤ 0.7D and 0.83D ≤ Y ≤ 1.5D; or (2) 0.4D ≤ X < 0.5D and 1.0D ≤ Y ≤ 1.5D. Thus, impurities intrude into the intercepting pipe (3).
