Example 2
The use method of the anti-interception-pollution main pipe backflow intelligent diversion well comprises the following steps:
s1, in the initial state, the drainage pump 4 is closed, the backflow prevention device 5 is closed, and the water inlet cavity 1 and the sewage interception cavity 2 are communicated;
s2, monitoring the positions of the real-time water level hj of the water inlet cavity, the real-time water level hw of the sewage intercepting cavity and the real-time water level hc of the water outlet cavity in real time, and recording data;
s3, in sunny days, the drainage pump 4 is correspondingly closed or closed according to the water level h2 (set maximum value), hw and hj of the water inlet cavity;
s31, if hw is less than or equal to h2, keeping the initial state;
s32, if hw is larger than or equal to h2, the drainage pump 4 is opened until hj is reduced to a water level h1 of the water inlet cavity (the set minimum value), and the drainage pump 4 is closed;
s33, when early warning of rainfall is received, opening the drainage pump 4 in advance until hj is reduced to h 1;
s4, when raining, the working mode of the drainage pump 4 is the same as that of sunny days, and the backflow prevention device 5 is opened or closed according to the flood discharge water levels h3, hc and hj;
s41, when hj is less than or equal to h3, the anti-backflow device 5 is in a fully closed state or a state that the weir crest is higher than hc;
s42, when hj is more than h3, hj is compared with hc, and if hj is less than hc, the closing state of the natural water backflow prevention device 5 is still kept;
s43, when hj is larger than h3, hj is compared with hc, if hj is larger than or equal to hc, the backflow preventing device 5 is started, and the drainage pump 4 is kept closed;
and S5, when the rainfall meter 9 detects that the rainfall is finished, closing the backflow preventing device 5 in a delayed mode, finishing the flood discharge state of the diversion well, and recovering the sunny working mode.
The working principle is as follows:
in sunny days, the backflow prevention device 5 is in a closed state, if the real-time water level hw of the sewage interception cavity 5 is less than or equal to the water level h2 of the water inlet cavity, sewage flows to the sewage interception cavity through the gravity of the impeller gap of the drainage pump 4 at the moment, and then enters the sewage interception main pipe through the sewage interception pipe 201.
If hw is more than or equal to h2, the water level of the sewage interception main pipe is higher, sewage cannot be discharged into the sewage interception main pipe by gravity, and the QJB-W pump is started at the moment, so that the sewage in the water inlet cavity is discharged to the sewage interception main pipe through the drainage pump 4; if the real-time hj of intake antrum water level is less than h1, flap valve 403 is in the closed condition this moment, prevents to cut dirty dry pipe water and pours into intake antrum 1 into.
And when the rainfall early warning is received, the QJB-W pump is started, and the water level of the water inlet cavity 1 is reduced to be below h1 in advance.
The flow of the QJB-W pump can be obtained by calculation according to (n +1) multiplied by Qdr, wherein Qdr is the dry season sewage amount, n is the design interception multiple, and the lift of the QJB-W pump is determined by calculation according to the maximum liquid level difference of the water inlet cavity and the interception cavity.
When raining, the real-time water level hw of the sewage intercepting main pipe rises, the amount of sewage entering the sewage intercepting main pipe is limited by the size of the water through hole of the QJB-W pump, the real-time water level hj of the water inlet cavity also gradually rises, and the working state of the QJB-W pump is consistent with that of a sunny day when hj is not more than h3 and reaches the flood discharge water level h 3. The anti-backflow device is kept in a fully closed state or a state that the weir crest is higher than hc, so that the natural water body is prevented from flowing backwards; after the real-time water level hj of the water inlet cavity reaches the flood discharge water level h3, namely hj is greater than h3, hj is compared with hc, and if hj is less than hc, the closing state of the natural water backflow prevention device is still kept; if hj is larger than or equal to hc, the backflow prevention device is opened, the diversion well enters a flood discharge state, and the drainage pump 4 is kept closed.
And when the rainfall meter 9 monitors that the rainfall is finished, the anti-backflow device 5 is closed in a delayed mode, the flood discharge state of the diversion well is finished, and the sunny working mode is recovered.
The above-mentioned embodiments are merely preferred embodiments of the present invention, and should not be considered as limitations of the present invention, and the protection scope of the present invention should be defined by the technical solutions described in the claims, and includes equivalent alternatives of technical features in the technical solutions described in the claims. I.e., equivalent alterations and modifications within the scope of the invention, are also intended to be covered by the scope of this invention.
