[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] In the collection of domestic sewage in towns and villages, rainwater and sewage are mostly collected together. At present, it is difficult to achieve complete diversion of rainwater and sewage. Due to the terrain, self-dug ditches and other reasons, combined pipes have crisscrossed under residential houses. In related technologies, rainwater and sewage collected by combined pipes are directly connected to sewage treatment plants. On rainy days, especially in seasons with heavy rainfall, the water flow rate increases greatly after sewage is superimposed on rainwater, causing a surge in water inflow to the sewage treatment plant, exceeding the treatment load of the sewage treatment plant, and causing the biochemical treatment system of the sewage treatment plant to collapse.

[0032] Reference Figures 1 to 3 As shown, a sewage pipe network interception device of an embodiment of the utility model includes an interception well 100, a first pipe 200, a second pipe 300, a third pipe 400 and a control component 500. The interception well 100 has a cavity inside; the first pipe 200 is arranged in the interception well 100, and the first pipe 200 has a first pipe opening 210 connected to the cavity; the second pipe 300 is arranged in the interception well 100, and the second pipe 300 has a second pipe opening 310 connected to the cavity; the third pipe 400 is arranged in the interception well 100, and the third pipe 400 has a third pipe opening 410 connected to the cavity, and the third pipe opening 410 is located above the second pipe opening 310 in the vertical direction; the control component 500 is arranged in the second pipe 300, and the control component 500 is used to adjust the flow size of the second pipe 300. The embodiment of the utility model can control the flow size of the combined pipe entering the sewage treatment plant, and ensure that the sewage treatment plant is not subjected to water shock load.

[0033] The first pipe 200 is used to connect to the existing combined pipe or other collection pipes for rainwater and sewage. The second pipe 300 is used to connect to the sewage treatment plant. Generally, sewage enters the interception well 100 through the first pipe 200, and then flows to the sewage treatment plant through the second pipe 300. Since the third pipe opening 410 of the third pipe 400 is above the second pipe opening 310 of the second pipe 300, the sewage enters the second pipe 300 first.

[0034] The control component 500 can adjust the flow rate of the second pipe 300. When the flow rate of sewage water increases, the flow rate of the second pipe 300 is limited by the control component 500, and the flow rate of the second pipe 300 is at the maximum flow rate limited by the control component 500, which can keep the water inflow of the sewage treatment plant constant. The control component 500 can adjust the flow rate through the second pipe 300 by limiting the cross-sectional area of ​​the second pipe 300.

[0035] On rainy days, rainwater mixes with sewage, causing the water flow rate of the first pipe 200 to increase sharply. In the early stage, the interception well 100 can collect part of the rainwater and sewage. When the water level in the interception well 100 rises to the third pipe opening 410, the excess rainwater and sewage overflow from the third pipe 400, reducing the impact of a large amount of rainwater on the sewage treatment plant in the later stage of rainfall, so there is no need to build an additional rainwater emergency pool.

[0036] Reference Figure 2 As shown, it can be understood that the control assembly 500 includes a gate 510 , and the gate 510 is disposed at the second nozzle 310 .

[0037] The control component 500 adjusts the flow of the second pipe 300 by limiting and changing the cross-sectional area of ​​the second pipe 300, for example, using a gate 510. The gate 510 is covered on the second pipe opening 310, and can move to change the opening size of the second pipe opening 310, that is, change the cross-sectional area of ​​the water flow effectively passing through the second pipe opening 310. Preferably, the gate 510 is an electric gate, which can reduce the difficulty of adjusting the gate 510 on the one hand, that is, no external force is required to be applied to the gate 510 manually; on the other hand, it can be used with a remote control system, and there is no need to arrive at the site to control the gate 510, which is convenient, fast and time-effective.

[0038] It is understandable that the control component 500 also includes a flow monitor 520, which is arranged inside the second pipe 300. When the gate 510 uses an electric gate, it can also cooperate with the real-time feedback of the flow monitor 520 to adjust the opening and closing size of the gate 510, and finally adjust the water flow of the second pipe 300 in real time, so that the amount of sewage entering the sewage treatment plant is at an optimal flow rate. Preferably, the flow monitor 520 can use an electromagnetic flowmeter. The measurement channel of the electromagnetic flowmeter is a smooth straight pipe. After connecting to the second pipe 300, it will not block the sewage flow, and will not cause pressure loss caused by flow monitoring. It is particularly suitable for pipe networks in towns and rural areas that rely on gravity to collect sewage. There is no need to add a pump to provide power, and the energy-saving effect is good.

[0039] Specifically, a regulating system is provided, the gate 510 is electrically connected to the regulating system, the flow monitor 520 is electrically connected to the regulating system, and the regulating system is used to obtain data from the flow monitor 520 to adjust the opening and closing degree of the gate 510.

[0040] It can be understood that the gate 510 includes a driving mechanism, a door body and a guide rail, the guide rail is arranged in the intercepting well 100, the door body cover is arranged on the second pipe opening 310, and the door body is slidably connected to the guide rail, the driving mechanism is connected to the door body, and the driving mechanism is used to drive the door body to move along the guide rail to change the area of ​​the second pipe opening 310 covered by the door body.

[0041] The guide rail may be a U-shaped rail, and the side of the door body may be inserted into the U-shaped rail so that the door body can move along the guide rail. The door body may be a flat-plate door body.

[0042] It can be understood that the driving mechanism includes a first motor and a screw rod, the screw rod is parallel to the surface of the door body, and the screw rod is passed through the door body, the door body and the screw rod cooperate for transmission, the screw rod is parallel to the guiding direction of the guide rail, and the first motor is connected to the screw rod for transmission.

[0043] The door body may be provided with a through hole, in which a thread matching the screw rod is processed. When the first motor drives the screw rod to rotate, the door body can be driven to move along the screw rod. Since the side of the door body is limited in the guide rail, the door body translates along the axial direction of the guide rail or the screw rod to change the area of ​​the door body covering the second pipe opening 310.

[0044] It can be understood that in the vertical direction, the lower limit position of the door body displacement is that the lower end of the door body is lower than the lowest point of the second pipe opening 310; the upper limit position of the door body displacement is that the lower end of the door body is higher than the highest point of the second pipe opening 310.

[0045] That is, the door cover is arranged at the second pipe opening 310, and the door moves upward to open the second pipe opening 310. The more the door moves upward, the larger the area of ​​the second pipe opening 310 is opened. When the water flows into the intercepting well 100, the liquid level moves from bottom to top, and the door also gradually opens from bottom to top, and the two cooperate better, making it more convenient to adjust the water flow.

[0046] It can be understood that the door body is provided with a plurality of guide wheels, and the guide wheels are in contact with the guide rails.

[0047] The guide wheel can convert the sliding friction between the door body and the guide rail into rolling friction between the guide wheel and the guide rail, which has smaller friction, smaller force required to adjust the movement of the door body, and the power consumption of the drive mechanism can be reduced.

[0048] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
