Rainwater collecting device for municipal construction

Abstract

A rainwater collecting device for municipal construction, comprising a draining groove, a water storage tank and a drain pipe; the draining groove is arranged at a low place of a roof; the water storage tank is embedded underground; the drain pipe is communicated between the draining groove and the water storage tank, and the drain pipe is provided with a impurity removing mechanism, a filtering mechanism and a cleaning mechanism; the filtering mechanism is arranged at a cross section of the drain pipe; the impurity removing mechanism and the cleaning mechanism are respectively arranged on inner walls of the drain pipe upstream and downstream of the filtering mechanism; the impurity removing mechanism is used for removing impurities in rainwater filtered by the filtering mechanism out of the drain pipe; the cleaning mechanism is used for dredging the filtering mechanism; the drain pipe is provided with a control mechanism for controlling the impurity removing mechanism, the filtering mechanism and the cleaning mechanism. The present application can collect water resources and reduce municipal drainage pressure.
