The invention discloses a novel intelligent rainwater and
sewage diversion intercepting well which comprises an intercepting well structure at the intersection of a confluence
pipe and a
sewage main
pipe and a diversion intercepting structure in the intercepting well structure, multi-working-condition self-adaptive operation is achieved through mechanical and hydraulic linkage, and the device is powered by a driving motor. The hydraulic linkage structure drives the pumping structure to form negative-pressure pumping and positive-pressure pumping effects,
sewage full-closure conveying in dry seasons and initial rain periods is achieved, meanwhile, the two-way sewage discharging spiral ribbon rod is linked, automatic dredging of
sludge in a well is synchronously completed, when
river water flows backwards, pure mechanical automatic blocking and backward flowing path blocking are achieved through the hydraulic linkage structure, a pressure feeding
pipe moves upwards to complete
butt joint of a one-way valve, and automatic dredging of
sludge in the well is achieved. Rapid drainage of large-flow rainwater is realized through an active drainage pipeline; after the extreme working condition is finished, the device can automatically reset to the conventional
cut-off working condition; the device is high in operation reliability and working condition adaptability, extra dredging power is not needed, the operation and maintenance cost is greatly reduced, overload of a sewage pipe network can be effectively avoided, and the requirements for rainwater and sewage diversion,
backflow prevention and dredging are met.
