Description

Technical Field

[0001] The utility model relates to the technical field of interception wells, in particular to an interception well with a backflow prevention function. Background Art

[0002] Interception wells are a type of well that collects polluted pits into one well and leads to a sewage treatment plant. Interception wells have long existed in the combined sewer system in my country's urban drainage projects. Their purpose is to separate rainwater and sewage. In the dry season, since there is only sewage in the pipe, the interception well can intercept the sewage and flow it into the newly built sewage pipe. In the rainy season, part of the rainwater and sewage are intercepted and flow into the sewage pipe, and the rest of the rainwater overflows through the weir in the well and continues to flow downstream.

[0003] For example, the patent website discloses an intercepting well with an anti-backflow function (publication number: CN220469064U). When this device is used to repair a water pump, a person needs to enter the separation pipe. Since sewage flows through the separation pipe, the separation pipe is very dirty, which makes it very difficult for people to repair the water pump in this environment. Therefore, technical personnel in this field have proposed an intercepting well with an anti-backflow function. Utility Model Content

[0037] like Figure 1-4 As shown, the water pump mechanism includes a strip plate 2, a threaded barrel 3, a rotating disk 4, a screw 5, a liquid pump 6, a telescopic output pipe 7, and a maintenance platform 8;

[0038] The maintenance platform 8 is installed on the inner wall of the intercepting well body 1, the strip plate 2 is installed on the inner wall of the intercepting well body 1 and is above the maintenance platform 8, the threaded barrel 3 is rotatably installed on the upper surface of the strip plate 2 and is co-centered with the intercepting well body 1, the turntable 4 is installed on the side of the threaded barrel 3, the screw 5 is arranged in the threaded barrel 3, the liquid pump 6 is arranged at the lower end of the screw 5, and the telescopic output pipe 7 is installed at the output end of the liquid pump 6 and the end extends to the outside of the intercepting well body 1;

[0039] When the liquid pump 6 needs to be inspected, a person enters the intercepting well body 1 and stands on the maintenance platform 8, then rotates the turntable 4 to drive the threaded barrel 3 to rotate and drive the screw 5 to rise, and the rising screw 5 drives the liquid pump 6 to rise until the liquid pump 6 moves above the maintenance platform 8, and then the staff can inspect the liquid pump 6. After the inspection is completed, the reverse turntable 4 drives the screw 5 to descend through the above operation to drive the liquid pump 6 to descend until the liquid pump 6 descends to the bottom;

[0040] like Figure 1-4 As shown, the maintenance chamber mechanism includes a maintenance chamber 9, a plate slot 10, an upper plate 11, a cavity 12, a limit plate 13, a spring 14, a clamp 15, a center slot 16, a winding rod 17, a pull rope 18, a clamping slot 19, a knob 20, and a maintenance ladder 27;

[0043] like Figure 1-4As shown, the main body mechanism includes a separation cylinder 21, a straight pipe 22, a solenoid valve 23, a connecting pipe 24, a solenoid check valve 25, a sewage pipe 26 and an exhaust pipe 28;

[0044] The separation cylinder 21 is installed at the center of the inner bottom surface of the intercepting well body 1, the straight pipe 22 is installed on the side of the intercepting well body 1 and close to the lower end, the solenoid valve 23 is arranged on the straight pipe 22, the connecting pipe 24 is arranged on the side of the separation cylinder 21, the solenoid check valve 25 is arranged on the connecting pipe 24, and the sewage pipe 26 is installed on the side of the intercepting well body 1 and close to the maintenance platform 8;

[0045] Sewage enters the intercepting well body 1 through the sewage pipe 26, and is then discharged from the straight discharge pipe 22. When the rainfall outside increases, the electromagnetic one-way valve 25 is opened to allow rainwater to enter the separation cylinder 21 through the connecting pipe 24. At the same time, the electromagnetic one-way valve 25 is an electromagnetic one-way valve, which will not allow the water in the separation cylinder 21 to flow back. Then the liquid pump 6 is operated to discharge the rainwater in the separation cylinder 21 through the telescopic output pipe 7. When the external water level is higher than the water level inside the intercepting well body 1, the electromagnetic valve 23 is closed to open the electromagnetic one-way valve 25, so that the separation cylinder 21 is connected to the intercepting well body 1, to prevent rainwater or sewage from flowing back into the intercepting well body 1 through the connecting pipe 24.
