Description
Technical field
The utility model is related to rainwater-collecting equipment technical field, specifically a kind of rain early-stage split-flow filter.
Background technology
Rainwater-collecting, complete saying be called " rainwater-collecting is with utilizing system ", refer to collect, utilize building room
The rainfall runoff that the hardening earth's surface such as top and road, square is collected, through collecting, --- channel such as water delivery --- water purification --- storage is accumulated
Store, rainwater collection be greening, landscape water body, washing and underground water source provides rainwater feed, with reach comprehensively utilize rainwater resource with
Water-saving purpose.Given birth to slowing down city rainwater flood and level of ground water decline, control rainwater runoff pollution, improving city
The wide significances such as state environment.Rainwater catchment system building, road, lake etc., collect rainwater, are used for Greenland Irrigation, landscape
Water, or foundation can ooze formula road surface, be mated formation using seepy material, directly increase the infiltration capacity of rainwater；But traditional rainwater-collecting
Device, it is impossible to effectively collect relatively clean rainwater, it is impossible to which automatic flow abandoning prophase programming carries the sewage of pollutant.
The content of the invention
The purpose of this utility model is to provide a kind of rain early-stage split-flow filter, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides following technical scheme：
A kind of rain early-stage split-flow filter, including shell, shell inner bottom part set dividing plate, and dividing plate is in shell inner bottom part
Formed and abandoned stream drain outlet is provided with sealed lower cavity, sealing cavity, the top of dividing plate correspondence abandoned stream drain outlet enters
The mouth of a river is provided with abandoned stream mouthful；The abandoned stream that abandoned stream drain outlet top is arranged on dividing plate is intraoral；Abandoned stream drain outlet passes through dividing plate
Abandoned stream mouthful is connected with shell upper cavity；Abandoned stream drain outlet bottom is connected with city planting ductwork；A left side for the shell upper cavity
Right both sides are symmetrically arranged with water inlet and delivery port；Abandoned stream mouthful top on dividing plate is provided with abandoned stream raft plate, the one of abandoned stream raft plate
End is hinged on the abandoned stream mouthful on dividing plate；Cover top portion is provided with support above abandoned stream raft plate；The abandoned stream raft plate other end passes through steel
Cord is connected across support with gravity ball float；The delivery port is connected with default rainwater-collecting pipe network.
It is used as further program of the utility model：In the shell permeable overflow is provided between water inlet and abandoned stream mouthful
Weir.
It is used as the utility model further scheme：In the shell screen pack is provided with delivery port.
Compared with prior art, the beneficial effects of the utility model are：
The utility model provides a kind of rain early-stage split-flow filter, and structure is novel；Rainwater enters outer by water inlet
Divide in shell through permeable downflow weir to after reduction of speed, the rainwater and pollutant produced during prophase programming passes through abandoned stream mouthful under abandoned stream valve plate and flowed
To city planting ductwork, when water-carrying capacity increases, reach after rainwater-collecting requirement；Water level rise gravity ball float with water level rise and on
Rise abandoned stream valve plate simultaneously to decline, close abandoned stream mouthful, the clean rainwater that rainwater filters minute impurities in water through screen pack passes through water outlet
Mouth, which enters, collects pipe network；When water level decreasing weight valve synchronously declines abandoned stream simultaneously in early-stage rainwater stream abandoning device cavity at the end of drop
Valve plate is opened, the next rainfall of the wait that restPoses.
