Regulating storage tank inflow control device for rainwater collection and waterlogging prevention
PendingCN107524214ASimple structureLow costSewerage structuresSewage drainingStormwater harvestingEnvironmental engineering
The invention provides a regulating storage tank inflow control device for rainwater collection and waterlogging prevention. The device comprises a case, and a dam which crosses the internal portion of the case, a water inlet pipe, a water outlet pipe, and at least one collection pipe which are arranged on the case. The internal space of the case is divided into a buffer room and a collection room by the dam. A collection opening communicated with the buffer room and the collection room is formed in the dam. Moreover, a switch device arranged on the collection opening controls the collection opening to be opened or closed. The water inlet pipe makes the buffer room and an external water inlet pipeline communicated, the water outlet pipe makes the buffer room and the external water outlet pipeline communicated, and the collection pipe makes the collection room and the regulating storage tank communicated. The regulating storage tank inflow control device for the rainwater collection and the waterlogging prevention is simple in structure and can further be suitable for existing various types of regulating storage tanks, can not only collect clean rainwater when rainstorm warning is not received, but also effectively prevent waterlogging when the rainstorm warning is received.

Centrifugal fan
The invention provides a centrifugal fan which can meanwhile restrain monomer noise of a centrifugal fan and resonance sound of equipment in the centrifugal fan. A cylindrical vane wheel formed by a plurality of blades vertically arranged on the external periphery of a rotary circular plate is accommodated in a volute; a cover plate provided with a bellmouth-shaped opening part and used for guiding air to inner sides of the vane wheel is employed to cover one end side of a rotary shaft on an axial direction. In addition, the opening part is eccentrically configured to be close to a tongue part (a connection part between a volute minor diameter side and an air supply path) and close to an opening center relative to the rotary shaft. Accordingly, compared with a case where the opening part is not eccentric, the centrifugal fan can narrow a disordered space caused by countercurrent on the periphery of the tongue part when air flows from the opening part to blades. As a result, the centrifugal fan can reduce an opening area of the opening part so as to restrain resonance sound, and monomer noise caused by turbulence caused by countercurrent.
