Description
Technical field
The invention belongs to urban drainage system, environmental protection technical field, be specifically related to a kind ofly based on PLC system there is the control device that dams of memory function.
Background technology
Along with the development of urbanization, the precontamination problem that town rain runoff causes becomes increasingly conspicuous.At present, be all generally by building catchpit and intercepting sewer is dammed into sewage conduct for cities and towns initial rainfall runoff, and be transported to Wastewater Treatment Plant and process.Therefore, catchpit is the key facility that initial rainfall runoff pollution controls.In practice, existing catchpit is to the control of primary rainwater closure amount or adopt overflow weir to be controlled by water level, the mechanical devices such as float valve are adopted to carry out semi-natural control, all can not realize accurately controlling the combined closure system of initial rainfall runoff, particularly accurately can not control according to the degree of contamination of initial rainfall runoff, intercepting sewer and soil pipe caliber not only may be caused to increase for this and sewage load increases, thus cause unnecessary economic input, and initial rainfall runoff pollution may be caused to be effectively controlled.
Summary of the invention
Realize initial rainfall runoff combined closure system to make catchpit accurately to control, particularly can realize accurately controlling according to initial rainfall runoff pollution degree (as concentration of suspension etc.), the present invention proposes and a kind ofly based on PLC system there is the control mode of damming of memory function.
The technical solution adopted in the present invention is:
There is the control device that dams of memory function, be made up of intelligent control box, drive unit, motor operated valve, water-level gauge, flow meter and/or online water quality testing meter.Described water-level gauge is arranged on peak level line position in catchpit, detects the water level signal in catchpit; Described shutoff valve is arranged in catchpit in intercepting sewer, closes or opens intercepting sewer; Described flow meter and/or online water quality testing meter are arranged on the waterline that pre-sets with upper/lower positions.Described intelligent control box adopts PLC system, and its input connects the signal output part of water-level gauge (or online water quality testing meter), and its output is connected with drive unit, and drive unit is connected with shutoff valve, to drive the keying of motor operated valve.When signal feedback is to intelligent control box, when water-level gauge flow meter and/or online water quality testing meter detect signal, command signal is sent after intelligent control box carries out the calculating of signal transformation assay by PLC system, the operation of accessory drive and stopping, and then pass through the keying of drive unit driving electric valve, thus accurately can control the size of combined closure system.
The present invention further provides and adopt the above control device that dams with memory function to carry out the method controlled of damming, comprise the following steps:
(1) by water-level gauge, flow meter or/and online water quality testing meter detects that water level in catchpit, flow are or/and water quality signal, by the PLC system of signal feedback to intelligent control box;
(2) carry out signal transacting by PLC system, process is as follows:
A, when water level arrive the waterline that presets of system or flow reach the flow that system presets time, the time t that PLC system is self registering when reaching

Or, if the rainfall runoff time of B23 whole field rainfall or flow are less than river closure time or combined closure system that system presets, before also not reaching the river closure time or combined closure system preset, PLC system just can't detect rain signal or flow signal, the signal fed back by water-level gauge is sent instruction by PLC system, and the shutoff valve that accessory drive realizes catchpit cuts out.
If when C water-level gauge detects that water level in catchpit arrives the peak level height of setting, PLC system sends instruction, open shutoff valve to maximum or send distant early warning signal by drive unit.
Adopt the inventive method, for the catchpit in conventional shunt drainage system, be provided with overflow weir control valve between rainwater water inlet pipe also in well and the storm drain road of overflow or jump, PLC system, while shutoff valve cuts out, controlling water kick weir control valve to open; When water level reaches peak level height, PLC system will control shutoff valve and overflow weir control valve is opened simultaneously.
For the rain sewage two-layer compound manhole in " rainwater, sewage two-layer compound manhole " (ZL200910104453.8), the unlatching size of cutoff hole maybe needs the water quality of damming to arrange according to concrete combined closure system.When water level exceedes manhole maximum stage, intelligent control box can send distant early warning signal.When can't detect rain signal (or flow signal), motor operated valve can according to intelligent control box send instruction morphing to predetermined state.
This control device that dams with the advantage of method compared with existing control mode of damming is: can with particular locality initial rainfall runoff over time feature be associated, the accurate control to combined closure system is realized according to the degree of contamination of initial rainfall runoff, realize the organic unity of combined closure system and Environmental capacity, thus realize the economic and practical of initial rainfall runoff pollution control and the best combination of environment friendly.

Or, if the rainfall runoff time of B23 whole field rainfall or flow are less than river closure time or combined closure system that system presets, before also not reaching the river closure time or combined closure system preset, PLC system just can't detect rain signal or flow signal, the signal fed back by water-level gauge is sent instruction by PLC system, and the shutoff valve that accessory drive realizes catchpit cuts out;
If when C water-level gauge detects that water level in catchpit arrives the peak level height of setting, PLC system sends instruction, open shutoff valve to maximum or send distant early warning signal by drive unit;
For catchpit or the jump well of conventional shunt drainage system, be also provided with overflow weir control valve, it is also connected with drive unit, is controlled by PLC system.
2. control method of damming according to claim 1, is characterized in that: for catchpit or the jump well of conventional shunt drainage system, and PLC system, while shutoff valve cuts out, controlling water kick weir control valve to open; When water level reaches peak level height, PLC system will control shutoff valve and overflow weir control valve is opened simultaneously.
3. control method of damming according to claim 1, is characterized in that: the unlatching size of the cutoff hole of rain sewage two-layer compound manhole maybe needs the water quality of damming to arrange according to concrete combined closure system.
4. control method of damming according to claim 1, is characterized in that: when water level exceedes manhole maximum stage, intelligent control box can send distant early warning signal.
5. control method of damming according to claim 1, is characterized in that: when can't detect rain signal or flow signal, shutoff valve can according to PLC system send instruction morphing to predetermined state.
6. control method of damming according to claim 1, is characterized in that: be also provided with flow meter and/or online water quality testing meter in described catchpit, their signal end is all connected with the input of intelligent control box.
