The working principle of the application is as follows: the flow converging pipe is mainly used for conveying domestic sewage and rainwater on a service area. In the drought period, the converging pipe conveys domestic sewage, and when rainfall occurs, the converging pipe conveys domestic sewage and rainwater, and the domestic sewage and the rainwater are mixed together to form converging sewage. When the rainfall is smaller or no rainfall exists, the amount of the converging sewage entering the rainwater intercepting well is lower than the intercepting multiple requirement of the intercepting well design, at the moment, the converging sewage when the rainfall is smaller or the domestic sewage when no rainfall exists enters the intercepting inspection well along the converging pipe and then enters the flow guiding groove first and flows between the flow guiding groove and the scum baffle filter screen through the intercepting groove, the converging sewage when the rainfall is smaller or the domestic sewage when no rainfall exists enters the space between the scum baffle filter screen and the intercepting inspection well where the buoyancy tank is located after being filtered by the scum baffle filter screen, and the water level in the space between the scum baffle filter screen and the intercepting inspection well where the buoyancy tank is located is lower than the lower end of the buoyancy tank, so that the buoyancy tank cannot receive the converging sewage when the rainfall is smaller or the buoyancy of the domestic sewage when no rainfall exists, namely the sluice is in an initial state, namely the sluice gate cannot conduct any blocking on the sewage pipe, and the converging sewage when the rainfall is smaller or the domestic sewage when no rainfall exists in the space between the scum filter screen and the intercepting inspection well can be discharged into the whole buoyancy tank;
along with the continuous rainfall or larger rainfall, the domestic sewage in the converging pipe has smaller relative rainwater amount, the ratio of rainwater in the converging sewage is very large, the water quality index of the converging sewage is better as a whole, the water quality is relatively clear, and in actual water treatment, the converging sewage can be directly discharged into a river channel generally; because the flow rate of the converging sewage in the converging pipe is very large when the rainfall is continuous or the rainfall is large, the converging sewage entering the rainwater intercepting well through the converging pipe far exceeds the design requirement of the intercepting multiple, at the moment, the converging sewage entering the intercepting inspection well along the converging pipe enters the flow guiding groove first, then the converging sewage can flow between the flow guiding groove and the scum baffle filter screen through the intercepting gutter, and part of the converging sewage directly flows into the next converging pipe connected with the intercepting rainwater well along the flow guiding groove, and after the rainwater flowing between the flow guiding groove and the scum baffle filter screen through the intercepting gutter is filtered by the scum baffle filter screen, the converging sewage also enters the space between the scum baffle filter screen where the buoyancy tank is positioned and the intercepting inspection well, and the water quantity of the converging sewage entering the intercepting inspection well increases, the water level of the space between the scum baffle filter screen and the intercepting inspection well where the buoyancy tank is located rises, the buoyancy tank begins to be stressed and slowly floats under the buoyancy action of the continuously rising confluent sewage, the buoyancy tank pulls the flashboard to move downwards under the action of overcoming the elasticity and friction force of the spring through the stay rope, the flashboard gradually seals the sewage pipe, when the flashboard completely seals the sewage pipe, the position of the bottom dead center of the flashboard is reached, the spring reaches the designed maximum deformation amount, the flashboard does not act any more, even if the water level of the space between the scum baffle filter screen and the intercepting inspection well where the buoyancy tank is located rises again, the buoyancy tank does not slowly float again along with the rising water level, and at the moment, a large amount of confluent sewage with larger rainwater content is discharged into a downstream water system river along another segment of confluent pipe connected with the intercepting inspection well; therefore, a large amount of rainwater can be effectively reduced from flowing into the sewage pipe, and high-load operation of sewage treatment of the sewage treatment plant is further caused.
And along with the rainfall reduction, the water level of the space between the scum baffle filter screen and the interception inspection well where the buoyancy tank is located can be reduced again, the buoyancy tank moves downwards along with the water level, the spring recovers deformation, the flashboard is restored to the initial position, namely the gate is in a fully opened state, the gate can not conduct any blocking on the sewage pipe, the follow-up interception sewage is convenient, and the circulation is repeated.
