A kind of novel automatic control catchpit
Technical field
The utility model relates to a kind of novel automatic control catchpit, especially comprises the novel automatic control catchpit of the dirty shunting of pit shaft and rain intelligence control system.
Technical background
At present, the dirty shunting of existing rain catchpit is mainly circular or square pit shaft, an overflow baffle is set before delivery port forms; Its shortcoming is that next interim when rainwater, sewage draining exit can't be closed automatically; Rainwater also can get into sewage network through sewage draining exit when covering the outside discharging of overflow baffle, dilute concentration of wastewater; Increase sewage load, increased the running cost of Wastewater Treatment Plant greatly.And, when outside water level is higher than overflow plate, not only can not blowdown, cause that on the contrary flow backwards advances to cut dirty pipe.
The utility model content
The technical problem that the utility model will solve provides a kind of novel automatic control catchpit, mainly is to solve rainwater temporarily, cuts closing automatically and the flow backwards problem of dirty mouth.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of novel automatic control catchpit; Comprise the dirty shunting of pit shaft and rain intelligence control system; The dirty shunting of said rain intelligence control system is made up of Based Intelligent Control cabinet, electronic Pollution discharge sluise gate, electronic draining deslagging gate, content gauge, and the input of Based Intelligent Control cabinet is connected with content gauge, and the output of Based Intelligent Control cabinet is connected with electronic Pollution discharge sluise gate, electronic draining deslagging gate respectively.
As the improvement of the utility model, said electronic draining deslagging gate is provided with spout hole, and the outside of spout hole is provided with flap valve, and the upper end of flap valve and electronic draining deslagging gate flexibly connect.
The cross section of said pit shaft is preferably square or circular.
Adopt such structure, the PLC system of Based Intelligent Control cabinet is according to the water level signal electronic Pollution discharge sluise gate of control, the opening and closing of draining deslagging gate automatically automatically that content gauge fed back, thus the dirty shunting of realization rain Based Intelligent Control.So just solved the problem that rainwater pours in sewage network and flow backwards automatically, effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-pit shaft cover plate, the 2-pit shaft, 3-collaborates water inlet pipe, 4-Sewage outlet; 5-storm-water drainage pipe, 6-access plate, 7-Based Intelligent Control cabinet, the electronic Pollution discharge sluise gate of 8-; The electronic draining deslagging of 9-gate, 10-flap valve, 11-content gauge, 12-spout hole.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
Fig. 1 shows the concrete structure of the utility model, and a kind of novel automatic control catchpit of the utility model comprises compositions such as pit shaft 2, Based Intelligent Control cabinet 7, electronic Pollution discharge sluise gate 8, electronic draining deslagging gate 9, flap valve 10.The cross section of pit shaft 2 be square or circular, it above be provided with pit shaft cover plate 1 and access plate 6, interflow water inlet pipe 3, Sewage outlet 4, storm-water drainage pipe 5 are arranged on the bottom of pit shaft 1; The dirty shunting of rain intelligence control system is made up of Based Intelligent Control cabinet 7, electronic Pollution discharge sluise gate 8, electronic draining deslagging gate 9, content gauge 11 etc.; The input of Based Intelligent Control cabinet 7 is connected with content gauge 11; The output of Based Intelligent Control cabinet 7 is connected with electronic Pollution discharge sluise gate 8, electronic draining deslagging gate 9 respectively, and the water level signal that the PLC system of Based Intelligent Control cabinet 7 is fed back according to content gauge 11 is the electronic Pollution discharge sluise gate of control 8, the opening and closing of draining deslagging gate 9 automatically automatically; Electronic draining deslagging gate 9 is provided with spout hole 12, and the outside of spout hole 12 is provided with flap valve 10, and the upper end of flap valve 10 and electronic draining deslagging gate 9 flexibly connect to realize the opening and closing of spout hole 12.
A kind of novel automatic control catchpit of the utility model is work like this:
When fine day or light rain sky, sewage gets into pit shaft 2 through interflow water inlet pipe 3, discharges to soil pipe through Sewage outlet 4 again; When moderate rain or when raining heavyly, rainwater gets into pit shafts 2 through the dirty interflow of rain water inlet pipe 3, and water level goes up fast, and the part rainwater will outwards be pushed flap valve 10 open and flows out from spout hole 12 when the pit shaft water level reaches predetermined water level line a; When the pit shaft water level reaches predetermined water level line b; The water level signal that the PLC system of Based Intelligent Control cabinet 7 is fed back according to content gauge 11 is made judgement in good time and is sent command signal; The action of the electronic Pollution discharge sluise gate 8 of control soil pipe; Close Sewage outlet 4, rainwater will all flow out from spout hole, no longer enter in the soil pipe.
After electronic Pollution discharge sluise gate 8 is closed; If spout hole 12 drainabilities are limited; Water level in the pit shaft 2 can continue to raise, and when arriving predetermined water level line c, the PLC system of Based Intelligent Control cabinet 7 can send instruction automatically according to the water level signal that content gauge 11 is fed back; Electronic draining deslagging gate 9 begins action, automatically opening water discharge.If water level continues to rise to predetermined water level line d, the Based Intelligent Control cabinet will send the remote alarms indication, and at this moment the staff will arrive on-the-spot investigation situation.
When rainwater reduces, during drawdown, Based Intelligent Control cabinet 7 can send instruction successively, closes electronic draining deslagging gate 9, opens electronic Pollution discharge sluise gate 8, sewage gets into soil pipe.So just solved the problem that rainwater pours in sewage network and flow backwards automatically, effectively.
