The adjustable plastic concrete mixed structure of interception ratio intelligently cuts dirty well

Technical field

The utility model is related to a kind of adjustable plastic concrete mixed structures of interception ratio intelligently to cut dirty well, belong to draining Engineering field, the more particularly to sewage of confluence of rainwater and sewage pipeline retain structures.

Background technology

Urban Drainage System is divided into separate system and combined system.Separate system is that two independent systems are respectively adopted in rainwater and sewage System is discharged, and rainwater is discharged into the water bodys such as river, and sewage is discharged into after sewage plant is handled by pipeline collection and is discharged into water body again.Interflow System is that rainwater and sewage are collected using a system, and sewage is carried out before being discharged into water body and is shut off, and sewage drains into dirt by cutting dirty pipe Water factory is handled, rainy day rainwater and sewage interflow, is directly discharged into water body beyond the flow that dirty pipe designs holding filth capacity is cut, collecting fitting is made Valence is relatively low.Many cities are using the run-off system of combined system the problems such as first stage of construction is due to population, fund, and some is even Shut off without sewage and is directly discharged into water body.First stage of construction is less serious to the pollution of water body since population is few, does not also obtain weight Depending on.With the development of economy, a large amount of sewage is directly discharged into water body and pollutes, people turn back again carry out environment control Reason.Section dirty pipe that either primary construction is just provided with the combined drainage system for cutting dirty pipe or later stage environmental improvement increases newly Road is directed to a kind of drainage structures --- and sewage intercepting chamber also referred to as cuts dirty well and hereinafter referred to as cuts dirty well.

The dirty well that cuts of the prior art mainly has downflow weir formula, great-jump-forward, flashboard type etc..Downflow weir formula cuts dirty well and belongs to water blocking Type is that downflow weir is arranged in cutting dirty well, usually there was only sewage in collecting fitting, and flow is smaller, is no more than the height of downflow weir, dirty Water, which is shut off by downflow weir blocking to a section dirty pipe, to be arranged to sewage plant, and rainy day sewage is mixed into rainwater cuts a dirty well, works as confluence of rainwater and sewage Flow increases, and when water level is more than the height of downflow weir, interflow water is overflowed from downflow weir is discharged into water body by cutting the delivery pipe of dirty well, Cut at this time in dirty pipe be filled with interflow water drain into sewage plant.Some cut dirty pipe and are not immediately discharged to sewage plant, but are connected to city Sewage pipe collects drains into sewage plant again, the pure sewage of the water inlet not just separate sewage system of such sewage treatment plant, also It is mixed into a large amount of confluence of rainwater and sewage water, since excessive interflow water and sewage are mixed into sewage plant, into the water quality of sewage plant And water, it is excessive in the difference of fine day and rainy day, very big difficulty is brought to sewage plant operation, while water inlet has exceeded sewage plant Processing capacity, sewage plant can only handle a part of sewage, and what it is beyond processing capacity is usually to be directly discharged into water body, is caused to environment Prodigious influence.Great-jump-forward section dirt well belongs to waterpower type, and the water inlet collecting fitting of section dirty well is managed higher than a section dirt and a delivery pipe, in utilization Trip collecting fitting water changes the flow curvilinear motion principle to be formed and cuts dirt, cuts between dirty pipe and delivery pipe and weir plate, collecting fitting is arranged When inflow is less than design combined closure system, intercepting sewer is fallen into water inlet, and when collecting fitting inflow is more than that design cuts dirty flow, water inlet is jumped Jump, which crosses weir plate and enters delivery pipe, is discharged into water body.Great-jump-forward, which cuts dirty well, to be discharged into water body by a large amount of interflow water, but still has one Branch, which falls into weir plate to flow into, cuts dirty pipe.Great-jump-forward cuts the collecting fitting that dirty well requires outlet drain pipe to be less than import, ability of intaking Jump crosses weir plate and enters delivery pipe, but section dirty well that transformation is added on existing collecting fitting, the collecting fitting and outlet drain of import Pipe can not be reduced in same absolute altitude since downstream line is discharged into the limitation of water body absolute altitude, thus cut dirt in existing collecting fitting In improvement project, great-jump-forward cuts the inadaptable of dirty well.Flashboard type cuts dirty well and belongs to mechanical, and the rainy day is by manually or electrically closing Flashboard is closed, interflow water, which does not enter, to be cut dirty pipe and be all discharged into water body, and sewage plant does not have the interflow water of excess to enter, and will not cause to locate Reason ability excess load.But flashboard type cuts dirty well and numerous dirty wells that cuts along section dirty pipe is needed to use manual control, operates It is inconvenient, it is in the majority still to cut dirty well with downflow weir formula and great-jump-forward in the prior art.

After rainfall, the water level decreasing of collecting fitting 2, the depth of water of the detection of ultrasonic sensor 12, flow reduce, and are less than and cut When staying multiple, the water concentration that water quality sensor 13 detects increases, and control unit 15 sends out instruction to motor 9, and motor 9 is through over-subtraction Fast device 10 slows down, and drives valve 8 to open by shaft 11 and cuts dirty mouth 7, sewage flows into sewage chamber 5 by cutting dirty mouth 7, then passes through dirt Water pipe 6 drains into sewage treatment plant, cuts dirty well and is restored to a section dirty operating mode.If water level and flow that ultrasonic sensor 12 detects reach When to interception ratio, and the change of water quality that sensor 13 detects in water is little, and the not up to requirement of direct emission water body at this time may be used It can be by chance rainfall less but upstream blowdown flow rate increases such as factory's central drainage, control unit 15 does not send out instruction and closes valve 8, Sewage is retained still through dirty mouth 7 is cut.

The open/close states of valve 8, by Internet transmission to monitoring center, are realized and are cut by control unit 15, transmission unit 16 The long-range monitoring of dirty well.Monitoring center can send out instruction, adjustment retention by the Internet transmission unit 16 to control unit 15 Multiple.The change working for cutting dirty well, by analyzing water level, flow, water quality parameter, 15 intelligent control of control unit constitutes intelligence Dirty well can be cut.

Power supply 17 includes solar panel and lithium battery.Lithium battery, control unit 15, transmission unit 16 are mounted on waterproof Instrument container in, the antenna of solar panel and transmission unit 16 is mounted on outside instrument container, and rainfall sensor 14 is mounted on instrument The top of device case, sees Fig. 8.
