Description
Technical Field
[0001] This application relates to the technical field of sewage recycling, and particularly to a plot sewage collection system. Background Art
[0002] Urban sewage needs to be collected by laying pipelines and can only be discharged after being treated by an urban sewage treatment plant. In recent years, the development of projects such as the protection of traditional villages and the renovation of old communities, which are important parts of urban renewal, faces challenges in that in a limited space, there is no condition for large-scale excavation or the need to preserve the style and features of traditional buildings, affected by terrain undulations. How to solve the problem of collecting small-flow sewage? Currently, most drainage systems adopted are rainwater-sewage separation, giving priority to gravity flow and assisted by pumping stations for lifting in this traditional way. This way is restricted by many conditions (terrain undulations, small space dimensions), with high costs, and sometimes it is very difficult for pipelines to be laid. The pipeline excavation depth and construction area are large, the space is limited, the inverted siphon pipeline across the river is prone to blockage, the construction cost is high, and too many sewage intercepting pumping stations are difficult to manage. Utility Model Content
[0003] In order to reduce the cost of sewage collection, this application provides a plot sewage collection system.
[0004] A plot sewage collection system provided by this application adopts the following technical solutions:

The front-end vacuum collection station includes a plurality of front-end collection pools, the front-end collection pools are buried underground, the negative pressure equipment central station includes a negative pressure pump device, the negative pressure pump device includes a main pump pipeline, the main pump pipeline is connected to a plurality of negative pressure branch pipelines, and the negative pressure branch pipelines are connected to the front-end collection pools.
[0006] By adopting the above technical solutions, the front-end vacuum collection station collects sewage through the front-end collection pools distributed throughout each plot, and then the negative pressure equipment central station centrally processes the sewage through precise negative pressure adsorption technology. Combining the front-end vacuum collection station, the intelligent induction device, and the negative pressure equipment central station realizes the distributed collection of plot sewage in each plot. The negative pressure equipment central station centrally transfers the collected sewage to the sewage treatment plant, which can simplify the sewage collection process and thus reduce costs. The front-end collection pools are buried underground and do not occupy ground space.
[0007] In a specific feasible implementation, a partition wall is provided in the front-end collection pool. The partition wall divides the front-end collection pool into an inflow pool and an outflow pool. The negative pressure branch pipeline is arranged in the outflow pool. The inflow pool is connected to a gravity inlet pipe, and a filter screen is arranged in the gravity inlet pipe.
[0008] By adopting the above technical solution, the height of the partition wall is lower than half of the pool, and the pool is divided into an inflow pool and an outflow pool. This design can not only temporarily store the incoming sewage, but also effectively eliminate the bubbles in the sewage and improve the adsorption efficiency of the negative pressure branch pipeline. At the same time, the laying of the negative pressure branch pipeline is more convenient and has lower cost compared to the combination of traditional sewer and pump.
[0009] In a specific feasible implementation, the negative pressure pump device further includes regulating valves, and each of the negative pressure branch pipelines is provided with a regulating valve.
[0010] By adopting the above technical solution, the negative pressure pump device is connected to the front-end collection pool through the negative pressure branch pipeline, and the negative pressure technology is used to adsorb and centrally treat the sewage. The setting of the regulating valve can be accurately adjusted according to the sewage discharge and production volume of different plots to achieve the purpose of energy saving.
[0011] In a specific feasible implementation, the front-end vacuum collection station further includes a storage battery and a solar panel, and both the solar panel and the storage battery are fixedly arranged on the ground.
[0012] By adopting the above technical solution, the system design is green and sustainable, using solar power supply, reducing environmental pollution.
[0013] In a specific feasible implementation, the intelligent sensing device includes a front-end communication device and a central communication device. The front-end communication device is arranged in the front-end vacuum collection station, and the central communication device is arranged in the negative pressure equipment central station.
[0014] By adopting the above technical solution, the front-end communication device and the central communication device can monitor the working status of the front-end vacuum collection station and the negative pressure equipment central station in real time.
[0015] In a specific feasible implementation, the intelligent sensing device further includes a liquid level sensor. The liquid level sensor is arranged in the outflow pool. The liquid level sensor includes a floating cavity, a fixed base, and a telescopic guide rod. The fixed base is fixed to the bottom of the outflow pool. The telescopic guide rod includes a first-stage rod and a second-stage rod. The first-stage rod is fixedly connected to the fixed base. A sliding hole is arranged in the second-stage rod, and the first-stage rod is slidably arranged in the sliding hole of the second-stage rod. The floating cavity is fixedly arranged at one end of the second-stage rod away from the first-stage rod.
[0016] By adopting the above technical solution, through devices such as liquid level sensors, vacuum sensors, and sewage flow sensors, the sewage treatment situation can be grasped in real time. Collecting the front-end environmental signals and transmitting them through communication devices can facilitate accurately grasping the operation conditions of each part, making corresponding adjustments for different operating environments, and achieving the technical effect of energy saving.
[0017] In a specific feasible embodiment, the intelligent sensing device further includes a pressure sensor, and the pressure sensor is fixedly arranged at the top of the first-stage rod.
[0018] By adopting the above technical solution, the pressure sensor is set to detect the lowest water level of the sewage. When the water level of the sewage is too low, it will cause the corresponding negative pressure branch pipe to do ineffective load. The pressure sensor cooperates with the regulating valve to close the ineffective load negative pressure branch pipe, thereby reducing the power of the negative pressure pump device and achieving the energy-saving effect.
[0019] In a specific feasible embodiment, the intelligent sensing device further includes a vacuum degree sensor and a sewage flow sensor, and both the vacuum degree sensor and the sewage flow sensor are arranged in the negative pressure branch pipeline.

[0022] 1. Through the combination of the front-end vacuum collection station and the negative pressure equipment central station, the distributed sewage collection and centralized treatment of the plot are realized. The front-end collection station collects sewage through the front-end collection pools distributed throughout the plot, and then the negative pressure equipment central station uses precise negative pressure technology to adsorb and centrally treat the sewage. This not only simplifies the sewage collection process, reduces costs, but also improves the efficiency of sewage treatment. The front-end collection pools are buried underground, occupying no ground space and being applicable to various plot environments. By setting partition walls, the front-end collection pools are divided into an inflow pool and an outflow pool. This design can not only temporarily store the incoming sewage, but also effectively eliminate the bubbles in the sewage and improve the adsorption efficiency of the negative pressure branch pipeline.

The introduction of the intelligent sensing device makes the monitoring and management of the system more intelligent. The settings of the front-end communication device and the central communication device can monitor the working status of the front-end vacuum collection station and the negative pressure equipment central station in real time. The use of the liquid level inductor, the vacuum degree sensor, and the sewage flow sensor can grasp the sewage treatment situation in real time and provide a decision-making basis for managers.

[0028] The following further elaborates on this application in conjunction with the attached Figures 1 - 3 drawings for a more detailed description.
[0029] In the description of the present utility model, it should be understood that for the orientation description, such as the orientation or positional relationship indicated by up, down, front, back, left, right, etc., is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.
[0030] The embodiment of this application discloses a plot sewage collection system for collecting the sewage of plot 5. Refer to Figure 1 and Figure 2, including a front-end vacuum collection station 1, an intelligent induction device, and a negative pressure equipment central station 4. The front-end vacuum collection station 1 includes a plurality of front-end collection pools 11, and the front-end collection pools 11 are buried underground. When actually arranging the front-end vacuum collection station 1, the city is divided into a plurality of plots 5, and one front-end vacuum collection station 1 is arranged as a unit for each plot 5. The front-end vacuum collection station 1 first centrally collects the sewage in the area where each plot 5 is located in each plot 5. A partition wall 12 is provided in the front-end collection pool 11, and the setting height of the partition wall 12 is lower than half of the height of the front-end collection pool 11. The partition wall 12 divides the front-end collection pool 11 into an inflow pool 13 and an outflow pool 14. A negative pressure branch pipeline 42 is arranged in the outflow pool 14. The inflow pool 13 is communicated with a gravity inlet pipe 15. The gravity inlet pipe 15 is inclined, and a filter screen 16 is arranged in the gravity inlet pipe 15. The filter screen 16 plays a filtering role. The gravity inlet pipe 15 is connected to the sewer of the plot 5 where it is located, and the sewer of the plot 5 where it is located is centrally flowed into the gravity inlet pipe 15 and then flows into the inflow pool 13 through the gravity inlet pipe 15. When the sewage flows into the inflow pool 13 through the gravity inlet pipe 15, bubbles will be generated under the action of gravity impact. The setting of the partition wall 12 can temporarily store the sewage entering from the gravity inlet pipe 15 first. When the sewage in the inflow pool 13 accumulates to a certain height, the sewage in the inflow pool 13 will cross the top of the partition wall 12 and flow into the outflow pool 14 along the side wall of the partition wall 12. The bubbles inside the sewage in the inflow pool 13 will automatically rise to the water surface and disappear. Therefore, the sewage with less bubble content at the top of the inflow pool 13 will flow into the outflow pool 14 first, thereby reducing the bubble content in the outflow pool 14. When the sewage flows along the outer surface of the partition wall 12, due to the increase in the surface area, this setting also helps to eliminate the bubbles.
[0031] Refer to Figure 3 , the negative pressure equipment central station 4 includes a negative pressure pump device 41. The negative pressure pump device 41 includes a main pump pipeline 43. The main pump pipeline 43 is communicated with a plurality of negative pressure branch pipelines 42. The negative pressure branch pipelines 42 are connected to the front-end collection pools 11. Through the separately provided negative pressure pump device 41, the negative pressure pump device 41 adsorbs and transfers the sewage in each front-end collection pool 11 through the negative pressure branch pipelines 42. The burial of the negative pressure branch pipelines 42 is smaller in volume and more convenient to bury compared to the burial of sewage pipelines, reducing costs.
[0032] Since the sewage discharge amounts of different plots 5 are different, and the sewage production at night and during the day varies greatly, the negative pressure pump device 41 further includes regulating valves, and each of the negative pressure branch pipelines 42 is provided with a regulating valve. The regulating valve is used to adjust the flow rate in each negative pressure branch pipeline 42. By changing the opening amplitude of the valve to change the flow rate, the negative pressure adsorption force of the negative pressure branch pipeline 42 can be adjusted according to the usage conditions of each branch pipeline and each plot 5, so as to achieve the technical effect of energy saving.
[0033] The front-end vacuum collection station 1 further includes a storage battery 17 and a solar panel 18, and both the solar panel 18 and the storage battery 17 are fixedly arranged on the ground. The solar panel generates electricity and stores it in the storage battery 17, and the storage battery 17 is used to supply power to the front-end vacuum collection station 1 to support the normal use of various electrical equipment in the front-end vacuum collection station 1.
[0034] The intelligent sensing device includes a front-end communication device and a central communication device. The front-end communication device is arranged in the front-end vacuum collection station 1, and the central communication device is arranged in the negative pressure equipment central station 4. The settings of the front-end communication device and the central communication device can establish a communication connection between the front-end vacuum collection station 1 and the negative pressure equipment central station 4, enabling sensors distributed at different positions to be transmitted through the front-end communication device and the central communication device, facilitating the back-end operators to grasp the situation at the front end in real time and monitor each front-end vacuum collection station 1.
[0035] The intelligent sensing device further includes a liquid level sensor 2. The liquid level sensor 2 is arranged in the outflow tank 14 and is used to detect the liquid level height. The liquid level sensor 2 includes a floating cavity 22, a fixed base 23, and a telescopic guide rod 21. The floating cavity 22 can provide buoyancy. The fixed base 23 is fixed to the bottom of the outflow tank 14. The telescopic guide rod 21 includes a first-stage rod and a second-stage rod arranged conventionally. The first-stage rod is fixedly connected to the fixed base 23. A sliding hole is arranged in the second-stage rod, and the first-stage rod is slidably arranged in the sliding hole of the second-stage rod. The floating cavity 22 is fixedly arranged at the end of the second-stage rod away from the first-stage rod. The floating cavity 22 can rise and fall with the sewage liquid level, thereby driving the first-stage rod and the second-stage rod to rise and fall. The intelligent sensing device further includes a pressure sensor 3, and the pressure sensor 3 is fixedly arranged at the top of the first-stage rod. When the second-stage rod presses on the pressure sensor 3, the pressure sensor 3 will trigger a signal. By presetting the position of the second-stage rod in advance, when the sewage in the outflow tank 14 is too low, the pressure sensor 3 will be triggered to generate a signal. To save system power consumption, when the pressure sensor 3 is triggered, the corresponding negative pressure branch pipeline 42 does not work.
[0036] The intelligent sensing device further includes a vacuum degree sensor and a sewage flow sensor. The vacuum degree sensor and the sewage flow sensor are both arranged in the negative pressure branch pipeline 42. The vacuum degree sensor is used to detect the vacuum degree of the negative pressure branch pipeline 42, and the vacuum degree sensor is used to cooperate with the feedback signal sensor set by the regulating valve, so that the vacuum degree sensor and the regulating valve cooperate to achieve precise control of the valve opening.
[0037] The implementation principle of the embodiment of this application is as follows: The front-end vacuum collection station 1 is arranged on each plot 5, and each plot 5 is provided with a front-end collection tank 11 for centrally collecting the sewage in the area of the plot 5. When the sewage in the sewer enters the inflow tank 13 through the gravity inlet pipe 15, due to the existence of the partition wall 12, the sewage will be temporarily stored in the inflow tank 13. As the sewage accumulates, the sewage liquid level rises accordingly, and the sewage that crosses the partition wall 12 will flow into the outflow tank 14. During this process, the bubbles generated by the gravity impact will be blocked by the partition wall 12 and rise to the water surface and disappear over time, thereby reducing the content of bubbles in the outflow tank 14.
[0038] The negative pressure pump device 41 of the negative pressure equipment central station 4 is connected to the front-end collection tank 11 through the negative pressure branch pipeline 42. The negative pressure pump device 41 generates negative pressure, adsorbs the sewage in the front-end collection tank 11 through the negative pressure branch pipeline 42, and pumps the sewage to the sewage treatment center through the negative pressure pump device 41. A regulating valve is arranged on each negative pressure branch pipeline 42. According to the usage conditions of each plot 5 and the sewage discharge volume, the flow rate is adjusted by changing the opening amplitude of the valve, so as to achieve the effect of energy saving.
[0039] The above embodiments only express the implementation manners of the utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
