[0011] When the sewage flow is large, the sewage outlet discharge volume is limited. As the sewage in the first sewage well continues to enter, the water level of the sewage in the first sewage well rises until it reaches the overflow port and overflows into the second sewage well. Then, it is transported through the overflow pipe and enters the third sewage well for subsequent discharge and treatment. When the sewage flows through the overflow pipe, the flow monitoring component monitors the sewage flow in real time, so as to facilitate the monitoring of the overflow volume at the sewage overflow port, so as to evaluate the ecological impact on the receiving water body, and monitor the plant network system load based on the data of the flow monitoring component.

[0021] By adopting the above technical solution, after the sewage enters the second sewage well from the overflow port, it can be first buffered in the lower part of the second sewage well, and then enter the third sewage well from the opening at the top of the overflow pipe, playing a sewage buffering role.
[0022] Optionally, the top of one end of the overflow pipe located in the second sewage well is gradually expanded.
[0023] The adoption of the above technical solution helps to guide the sewage in the second sewage well into the overflow pipe.

The buffer wall is a wall structure, so it has a high structural strength, is not easily damaged by the impact force of sewage, has high structural stability, and has a long service life.

[0035] The following is combined with Figure 1-4 This application is described in further detail.
[0036] Example 1
[0037] The present application embodiment discloses an overflow sewage monitoring device. Figure 1 The overflow sewage monitoring device includes an overflow pipe 1, a flow monitoring component 2, and a first sewage well 3, a second sewage well 4, and a third sewage well 5 arranged from right to left. The cross section of the first sewage well 3 is circular, and the cross sections of the second sewage well 4 and the third sewage well 5 are square. A sewage inlet 31 and a sewage outlet 32 are arranged at the lower side of the first sewage well 3. The sewage inlet 31 is provided with two, one large and one small, and the two sewage inlets 31 are respectively located on the opposite sides of the first sewage well 3. An overflow port 33 is arranged on the upper side of the first sewage well 3, and the overflow port 33 is connected to the second sewage well 4 through a pipeline. The overflow pipe 1 is made of a reliable anti-corrosion welded steel pipe. One end of the overflow pipe 1 passes through the second sewage well 4 and extends to the overflow port 33 to be connected to the overflow port 33. The other end of the overflow pipe 1 passes through the third sewage well 5 and extends upward to the middle of the third sewage well 5. One section of the overflow pipe 1 is a flow monitoring section 11 , and the flow monitoring component 2 is disposed on the flow monitoring section 11 . In the embodiment of the present application, the flow monitoring component 2 is an ultrasonic flow meter.
[0038] Sewage enters the first sewage well 3 from the sewage inlet 31. When the sewage flow is small, the sewage is directly discharged from the sewage outlet 32. When the sewage flow is large, the sewage outlet 32 has a limited discharge volume. As the sewage in the first sewage well 3 continues to enter, the water level of the sewage in the first sewage well 3 rises until it reaches the overflow port 33 and overflows into the second sewage well 4. Then, it is transported through the overflow pipe 1 and enters the third sewage well 5 for subsequent discharge and treatment. When the sewage flows through the overflow pipe 1, the flow monitoring component 2 monitors the sewage flow in real time, so as to facilitate the monitoring of the overflow volume at the sewage overflow port 33, so as to facilitate the evaluation of the ecological impact on the receiving water body, and at the same time, the plant network system load is monitored according to the data of the flow monitoring component 2.
[0039] Reference Figure 1The overflow pipe 1 is provided with an anti-backflow valve 6 at one end connected to the third sewage well 5. The anti-backflow valve 6 adopts a duckbill valve, which can prevent the sewage in the third sewage well 5 from flowing back, facilitate the forward discharge of sewage, reduce the impact on the flow monitoring component 2, and improve the accuracy of sewage flow monitoring. The second sewage well 4 and the third sewage well 5 are arranged adjacent to each other, and the overflow pipe 1 passes through one end of the second sewage well 4 and is connected to the overflow port 33. The flow monitoring section 11 is vertically arranged in the second sewage well 4, thereby saving installation space.
[0040] Example 2
[0041] The difference between this embodiment and embodiment 1 is that, referring to Figure 2 The cross-sections of the first sewage well 3, the second sewage well 4 and the third sewage well 5 are all circular, and the second sewage well 4 and the third sewage well 5 are spaced apart. The overflow pipe 1 passes through one end of the second sewage well 4 and is connected with the overflow port 33. The flow monitoring section 11 is horizontally arranged at the interval between the second sewage well 4 and the third sewage well 5. The interval between the second sewage well 4 and the third sewage well 5 has a wide field of view, which facilitates the installation of the flow monitoring component 2.
[0042] Example 3
[0043] The difference between this embodiment and embodiment 2 is that, referring to Figure 3 The overflow port 33 is arranged at the middle side of the first sewage well 3, and a dirt intercepting grid 331 is arranged at the overflow port 33. The dirt intercepting grid 331 can intercept the scum in the sewage, reduce the deposition of scum in the flow monitoring section 11, thereby reducing the metering error of the flow monitoring component 2, and prolonging the service life of the flow monitoring component 2. In addition, one end of the overflow pipe 1 passing through the second sewage well 4 is located in the second sewage well 4 and the opening faces upward. The height of the end of the overflow pipe 1 located in the second sewage well 4 is close to the height of the overflow port 33. After the sewage enters the second sewage well 4 from the overflow port 33, it can be first buffered in the lower part of the second sewage well 4, and then enter the third sewage well 5 from the opening at the top of the overflow pipe 1, playing a sewage buffering role. The top of the end of the overflow pipe 1 located in the second sewage well 4 is gradually expanded, which helps to guide the sewage in the second sewage well 4 into the overflow pipe 1.
[0044] Example 4
[0045] The difference between the present embodiment and the embodiment 3 is that, Figure 4The flow monitoring component 2 in the embodiment of the present application adopts a flow monitoring probe, and the flow monitoring probe is installed in the flow monitoring section 11. One end of the overflow pipe 1 passing through the second sewage well 4 is located at the lower part of the side wall of the second sewage well 4. A buffer wall 7 is fixedly installed in the middle of the bottom surface of the second sewage well 4. The buffer wall 7 divides the interior of the second sewage well 4 into a buffer space 71 and a diversion space 72. Compared with the diversion space 72, the buffer space 71 is closer to the overflow port 33 and is connected to the overflow port 33. The diversion space 72 is connected to the end of the diversion pipe passing through the second sewage well 4.
[0046] After the sewage passes through the overflow port 33 from the first sewage well 3, it will first enter the buffer space 71 for buffering, and then overflow from the top of the buffer space 71 to the guide space 72, and then enter the third sewage well 5 through the overflow pipe 1. The buffer wall 7 is a wall structure, so it has a high structural strength, is not easily damaged by the impact force of sewage, has a high structural stability, and has a long service life.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
