As shown in fig. 5, in order to realize automatic control, the first water level gauge 1.6, the second water level gauge 2.2, the third water level gauge 1.7 and the fourth water level gauge 8.6 transmit monitored water level information to a control system (namely a PLC) in real time, and the control system respectively controls a first motor 4.3 of a water quantity adjusting gate assembly, a second screw rod stepping motor 7.1 of a grid cleaning assembly, a second motor 3.2 of a sewage draining gate assembly, a first screw rod stepping motor 5.2 of a filtering chamber gate assembly, a water supply electromagnetic valve 7.6, a sewage draining electric valve 8.2 and a sewage draining pump 8.5 according to the water level information to realize automatic interception and automatic filtration of sewage, automatic cleaning of a grid and automatic operation control of impurity draining; the control system is connected with an upper computer (the upper computer is a computer, a tablet or a mobile phone) through a wireless transceiver module, and the remote control of the running state is realized through the mobile phone or the computer in real time and remote monitoring.
The specific working process of the invention is as follows:
In the system operation, the second water level gauge 2.2 monitors the water level of the water storage tank 2.1 in real time, when the water level in the water storage tank 2.1 is in a preset water level required to be supplemented, the control system sends a command to the first motor 4.3 of the water quantity adjusting gate assembly, so that the adjusting gate 4.2 falls down to start intercepting sewage, and the water level in the sewage adjusting chamber 1.1 is raised; the control system simultaneously instructs a first screw rod stepping motor 5.2 of the filter chamber gate assembly, then drives the filter chamber gate 5.1 to lift and supply water to the sundry filter chamber 1.2, sewage enters the water storage tank 2.1 through the water receiving port 1.5 after three-stage filtration of the first grating plate 6.1, the second grating plate 6.2 and the third grating plate 6.3, and automatic adjustment of the water interception capacity and the filtered water capacity is implemented so as to ensure the water consumption of the subsequent deep purification treatment;
When the water level of the water storage tank 2.1 reaches the water level (the water level in the water storage tank 2.1 reaches the preset highest water level), the control system sends a command to the first motor 4.3 of the water quantity adjusting gate assembly at the moment so that the adjusting gate 4.2 is lifted upwards, and sewage entering the sewage adjusting chamber 1.1 from the original upstream sewage pipeline directly enters the original downstream sewage pipeline through the water outlet 1.4; meanwhile, the control system sends out an instruction to the first screw rod stepping motor 5.2 of the filter chamber gate assembly, drives the filter chamber gate 5.1 to fall, closes a passage for sewage to enter the sundry filter chamber 1.2, stops filtering, and further realizes automatic adjustment, automatic filtering and automatic water collecting operation of the collected water quantity.
The impurities intercepted by the grating filter assembly are filtered, a part of the impurities can sink into a sewage disposal channel 3.3 on the bottom wall of the impurities filter chamber 1.2 (the sewage disposal gate 3.1 is in a vertical closing state in the filtering process), a part of the impurities can be adsorbed on the surface of the grating plate, and a part of the impurities can block the filtering holes of the first grating plate 6.1, the second grating plate 6.2 and the third grating plate 6.3, so that the grating plate surface of the grating filter assembly is required to be cleaned regularly and impurities deposited in the sewage disposal channel are required to be removed.
The control system presets a time section for cleaning the grid filter assembly, in a cleaning time section, the control system firstly instructs the first motor 4.3 to lift the gate so as to reduce the water level of the sewage regulating chamber 1.1, meanwhile, instructs the first screw stepping motor 5.2 to work so as to enable the filter chamber gate 5.1 to fall down, closes a water inlet channel of the sundry filter chamber 1.2, and after the water level of the sewage regulating chamber 1.1 detected by the first water level meter 1.6 reaches a set proper sewage draining water level and no water circulation is detected by the third water level meter 1.7, the control system sends working instructions to the second screw stepping motor 7.1 and the water supply electromagnetic valve 7.6, the second screw stepping motor 7.1 drives the gate-shaped bracket 7.3 to drive the lower cleaning roller 7.4 and the upper cleaning spray pipe 7.5 to reciprocate up and down along the lifting slide way, the lower cleaning roller 7.4 rolls and cleans sundries attached on the grid surface and blocking the filter holes, and the surface of the lower cleaning roller 7.4 cleans the surface of the grid surface and the lower cleaning roller 7.4, and the sundries fall down to the sewage draining channel 3.3, so that the filtered water is reserved in the water spraying way;
Before the grid cleaning reaches the set stop time, the control system instructs the first screw rod stepping motor 5.2 to lift the filter chamber gate 5.1, simultaneously instructs the second motor 3.2 of the drain gate assembly to drive the drain gate 3.1 to turn up, opens the drain channel 3.3, intercepts the impurities remained in the drain channel 3.3 and the impurities cleaned by filtration, discharges the impurities into the sewage regulating chamber 1.1 by utilizing the downward leakage force of water flow, and then discharges the impurities into the original downstream drain pipeline. If the cleaning time period is entered and the water level detected by the first water level gauge 1.6 is not suitable for sewage disposal, when the sewage level is reached, the control system instructs the grille cleaning and sewage disposal work flow to be entered.
Of course, the invention can also collect the filtered and washed sundries in the sundry discharging and collecting assembly, and the specific flow is as follows: when the grid cleaning is about to reach the set stop time, the control system controls the sewage gate 3.1 to turn up to open the sewage channel 3.3, and simultaneously opens the sewage electric valve 8.3, so that the impurities and sewage which are reserved or washed out flow into the impurity filtering water tank 8.4 below under the action of gravity, most filtered impurities are intercepted by the impurity filtering water tank 8.4, and the filtered fine impurities and sewage fall into the sewage collecting tank 8.2; when the water level detected by the fourth water level meter 8.6 reaches the highest water level of the sewage collecting tank 8.2, the control system controls the sewage pump 8.5 to work, and sewage in the sewage collecting tank 8.2 is discharged into the original downstream sewage drain pipe until the water level in the sewage collecting tank 8.2 reaches the lowest water level. Meanwhile, sundries on the sundry filtering water tank 8.4 are cleaned regularly, the sundry filtering water tank 8.4 slides to a designated position along the push-pull slideway, then the sundry filtering water tank 8.4 is lifted by the crane, the bottom wall of the sundry filtering water tank 8.4 is opened to enable the sundries to automatically fall into the cleaning vehicle, and the concentrated collection and automatic cleaning processes of the filtered sundries are realized.
After the sewage discharge is finished, the control system sends working instructions to the second screw rod stepping motor 7.1 and the water supply electromagnetic valve 7.6 to stop cleaning and spraying water; and simultaneously, an instruction is sent to the second motor 3.2 of the sewage gate assembly, so that the driving gate 3.1 is turned downwards to close the sewage channel 3.3, and the automatic cleaning of the grating filter assembly and the automatic sewage discharging work flow of sundries are completed.
When the intelligent water level monitoring system works, fault information of the running states of all components can be processed and then sent to a mobile phone of a maintainer, and remote supervision of system running is realized, if when the water level detected by the second water level meter 2.2 is in a water supplementing level (water supplementing is needed by the water storage tank 2.1), the water flow information in the water collecting port 1.5 cannot be always detected by the third water level meter 1.7, and the water level information detected by the first water level meter 1.6 in a cut-off period is always in a low water level, the specification water quantity regulating gate 4.2 does not fall or falls in place, so that cut-off failure is caused; if the water level information detected by the first water level gauge 1.6 is at the medium water level or the high water level after a period of time (i.e. the water level detected by the first water level gauge 1.6 is gradually raised), the filtering chamber gate 5.1 is not lifted and opened according to the instruction, so that the grid is blocked from water inflow, or the grid is not cleaned in place, the filtering holes of the grid plate are seriously blocked, sewage cannot be filtered, and water supplementing to the water storage tank is affected.
