Description
Technical field
The utility model relates to a kind of rain water drainage system.
Background technology
Rain water drainage referred at the rainfall initial stage, rainwater is washing away earth's surface, is being mingled with a large amount of impurity, such as having dissolved the pollution gas such as a large amount of sour gas, plant gas, vehicle exhaust in rainwater, therefore early stage, rainwater pollution degree was higher, had conventionally surpassed the degree of contamination of common municipal sewage; From economic angle, consider, the cost of its processing is higher, so just started this part rainwater, generally need to carry out abandoned stream processing.
Lighter rainwater of rainfall later stage, degree of contamination, after the processes such as suspension, solid particle polluter, precipitation and filtration in trap water, just can reach the standard of recycling.
Existing rain water drainage is generally taked following mode: one, in flow abandoning apparatus, be provided with float valve, along with water level raises, float valve is closed gradually, after collecting a certain amount of rainwater, float valve is closed completely, early-stage rainwater enters sewage conduct or suitable osmosis system, and the rainwater after abandoned stream flow to collection conduit; This device simple structure is practical, but needs manual maintenance.Two, by Storm Sewer Network, collect the rainwater of watershed, at Storm Sewer Network end, do the drainage tank of an abandoned stream amount of rainfall size, early stage, rainwater flowed into drainage tank, the stormwater overflow of middle and later periods flows into rain water reservoir system, after rainfall finishes, by submersible pump, the rainwater in drainage tank is got to downstream Storm Sewer Network, for next rainfall abandoned stream.
Take common one residential as example, 20000m
2watershed (hard surfacing or roofing), the amount of precipitation that calculates 3mm be the amount of rainfall of abandoned stream in early stage, getting runoff coefficient is 0.9, abandoned stream amount of rainfall is Q=20000 * 0.003 * 0.9=54m in earlier stage
3, need to build a 54m
3drainage tank, construction costs is higher, floor space is large, and after each rainfall, all needs pump to promote the rainwater in drainage tank, energy consumption is large.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of rain water drainage system, and to reach, construction costs is low, the object of convenient operating maintenance, saving energy consumption.
For achieving the above object, the technical solution of the utility model is as follows:
A rain water drainage system, comprises rainwater shunting well, the rainwater collection collector being communicated with described rainwater shunting well, abandoned stream device well, downstream rain pipe; In described rainwater shunting well, be provided with water quality sensor, between described rainwater shunting well and described abandoned stream device well, be provided with PLC Split-flow Control cabinet, described water quality sensor is connected with described PLC Split-flow Control cabinet; In described abandoned stream device well, be provided with motor operated valve, described PLC Split-flow Control cabinet is connected with described motor operated valve.
Further, described rainwater shunting well and described abandoned stream device well are equipped with grid.
Further, described abandoned stream device well and reservoir system connectivity.
Further, described water quality sensor is transmissometer, and described transmissometer output signal is 4-20mA.
Pass through technique scheme, a kind of rain water drainage system that the utility model provides, transmissometer can instantaneous detection water quality situation, output signal is to PLC Split-flow Control cabinet, can show after treatment water turbidity and contrast with the turbidity controlling value of setting, the motor operated valve that PLC output signal is controlled in abandoned stream device well opens, cuts out; Abandoned stream device well is similar with general catch-basin size, and cost is low, floor space is little, and whole system is that PLC controls, convenient operating maintenance, and applicability is strong.

The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The utility model provides a kind of rain water drainage system, with reference to figure 1, comprises rainwater shunting well, the rainwater collection collector being communicated with rainwater shunting well, abandoned stream device well and downstream rain pipe, abandoned stream device well and reservoir system connectivity; With reference to figure 2, in rainwater shunting well 2, being provided with output signal is the water quality sensor 4(transmissometer of 4-20mA), rainwater shunting well 2 is respectively equipped with grid 3 and grid 7 with abandoned stream device well 6, and water quality sensor 4 is connected with PLC Split-flow Control cabinet 5; In abandoned stream device well 6, be provided with motor operated valve 8, PLC Split-flow Control cabinet 5 is connected with motor operated valve 8.
With reference to figure 2, the rainwater at rainfall initial stage gathers through Storm Sewer Network, and flow into rainwater shunting well 2 by rainwater collection collector 1, water quality sensor 4(transmissometer) can instantaneous detection Rainwater Quality, and export 4-20mA signal to PLC Split-flow Control cabinet 5 according to the muddy degree of water, after PLC processes, can show water turbidity, contrast with a turbidity controlling value of setting, this turbidity controlling value is adjustable.
Early stage, muddy rainwater turbidity was greater than turbidity controlling value, and motor operated valve 8 valves that PLC Split-flow Control cabinet 5 is controlled abandoned stream device well 6 are closed condition, and muddy rainwater flows into downstream Storm Sewer Network; When the turbidity of rainwater is during lower than turbidity controlling value, illustrate that now water quality is cleaner, it be opening that PLC Split-flow Control cabinet 5 output signals are controlled motor operated valves 8, rainwater enters reservoir system for recycling or time permeating the ground; As long as grid 3,7 meets corresponding water velocity and grid amount.
In sum, the utility model rain water drainage system is that PLC controls, convenient operating maintenance, and adjustable range is wide, and applicability is strong, can meet client and more select; Rainwater shunting well 2 is similar with general catch-basin size with abandoned stream device well 6, and cost is low, and floor space is little, and rainwater flows to and is all gravity current, saves energy consumption.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of above-described embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
