Abstract
Description
Technical Field
[0001] This application relates to wastewater collection and treatment, and in particular to a smart siphon negative pressure collection system for rural wastewater. Background Technology
[0002] With the widespread availability of rural water supply facilities and the significant improvement in residents' living standards in my country, the discharge of rural domestic sewage has experienced explosive growth. Rural sewage originates from a wide range of sources, encompassing various types such as kitchen wastewater, washing wastewater, and toilet flushing wastewater, and its composition is complex and dispersed. Furthermore, given my country's extensive water system and the large number of rural residences built along rivers, conventional sewage collection pipe laying methods are difficult to implement. Therefore, the installation of sewage collection pipes along rivers has become a key measure to solve the problem of rural sewage discharge.
[0003] Currently, for areas near rivers with good building foundations, the common practice is to use a pipe-supported collection method where sewage collection pipes are attached to the outside of the foundation or retaining wall using supports and hangers. This structure mainly consists of sewage collection branch pipes, main pipes, supports and hangers, and fixed connectors. The collection branch pipes are securely installed on the outside of the building foundation or retaining wall using supports and hangers, and then each branch pipe is connected to the main pipe to achieve centralized collection and transportation of sewage.
[0004] However, in areas with high groundwater levels, trenching for pipe laying is prone to seepage. Construction of conventional gravity pipe networks in these areas requires dewatering or support of the foundation pit, resulting in high construction costs. In sensitive waterways and riverside villages, it is difficult to lay outlets and gravity pipes along the river, leading to direct discharge of sewage into the river. Pipelines laid along the river have poor sealing, causing significant sewage leakage and pollution. In some rural areas with dense housing and complex underground pipelines, traditional gravity pipe excavation requires slope and burial depth, making pipeline avoidance difficult, and excessive excavation can damage house foundations. Therefore, a smart siphon negative pressure collection system for rural sewage is proposed to address these issues. Utility Model Content
[0005] The purpose of this application is to provide a smart siphon negative pressure collection system for rural sewage, which aims to improve the problems of high groundwater levels, easy seepage in foundation pits when digging pipe trenches, sensitive water areas and villages along rivers, difficulty in laying discharge outlets and gravity pipelines along rivers, direct discharge of sewage and wastewater into rivers by villagers, and the difficulty in avoiding obstacles when excavating traditional gravity pipelines due to slope and burial depth requirements.
[0006] The intelligent siphon negative pressure collection system for rural sewage provided in this application adopts the following technical solution:
[0007] A smart siphon negative pressure collection system for rural sewage includes a vacuum well, a negative pressure collection mechanism inside the vacuum well, a connection interface fixedly connected to the outside of the connection interface inside the vacuum well, a drainage pipe fixedly connected to the inside of the vacuum well, a ball valve fixedly connected to the outside of the drainage pipe, a vacuum valve fixedly connected to the top of the drainage pipe, a water inlet pipe at the bottom of the drainage pipe, a fixing component at the top of the drainage pipe, a central control column connector fixedly connected to the outside of the vacuum well, an overflow outlet fixedly connected to the front of the drainage pipe, and a user drainage pipe fixedly connected to the outside of the drainage pipe.
[0008] As a further description of the above technical solution, the system achieves efficient sewage collection and intelligent treatment through the coordinated operation of various components. Sewage flows into the vacuum well through the user's drain pipe. When the water level reaches the set value, the vacuum valve opens. Under the negative pressure environment formed by the negative pressure power center, the sewage is quickly sucked into the negative pressure collection pipe through the inlet and outlet pipes and transmitted to the municipal pipe network or purification facilities. The ball valve can flexibly control the water flow interruption, which is convenient for system maintenance. The overflow pipe serves as a safety guarantee, which discharges excess sewage in time in case of system failure to prevent the vacuum well from overflowing. The connection port of the central control column realizes data interaction with the control system, supports remote monitoring and operation, and ensures efficient, stable and intelligent operation of the sewage collection and treatment process.
[0009] Preferably, the fixing component includes a toothed hanger, the bottom end of which is fixedly connected to the top end of the drainage pipe, and a wall-mounted fixture is fixedly connected to the outside of the vacuum well;
[0010] As a further description of the above technical solution, the toothed jack provides stable support to the drainage pipe from the top, preventing it from shaking or shifting due to force during negative pressure suction, thus ensuring the stability of sewage transportation. The wall-mounted design enhances the overall structural strength and installation stability of the vacuum well by fixing it to the wall or other supporting structure. Especially in rural areas with complex terrain or high groundwater levels, it effectively prevents the vacuum well from tilting or shifting, ensuring the long-term reliable operation of the entire sewage collection system.
[0011] Preferably, the wall thickness of the vacuum well is 2 mm, and the shape of the vacuum well is L-shaped;
[0012] As a further description of the above technical solution, the 2mm thick vacuum well is made of high-strength corrosion-resistant material, which reduces material costs while ensuring structural strength and compressive strength, thus meeting the economic needs of rural sewage collection projects.
[0013] Preferably, the two toothed hangers are arranged in an array at the top of the drain pipe.
[0014] As a further description of the above technical solution, the array distribution of the dental hangers improves the overall stability of the device.
[0015] Preferably, the internal array of the vacuum well is provided with multiple connection interfaces.
[0016] As a further description of the above technical solution, the multiple connection interfaces distributed in the internal array can be connected to multiple user drainage pipes simultaneously, which greatly improves the coverage and efficiency of sewage collection, flexibly adapts to the characteristics of rural decentralized residences, significantly improves the rural sewage collection rate, and helps rural sewage treatment.
[0017] Preferably, the external part of the drainage pipe is slidably connected to the inside of the vacuum well.
[0018] As a further description of the above technical solution, the sliding connection of the drainage pipe improves the efficiency of installation.
[0019] In summary, this application includes at least one of the following beneficial technical effects:
[0020] In this invention, when the system is running, sewage from various locations first flows into a vacuum well for temporary storage by gravity. When the water level reaches the standard, the vacuum valve automatically opens. Under the negative pressure environment created by the negative pressure power center, the sewage is quickly drawn into the negative pressure collection pipe through multiple pipes. The collection tank, generation system, and sewage discharge system in the negative pressure power center work closely together to efficiently transport the collected sewage to the municipal pipe network or treatment facilities. The entire system realizes the fully automated operation of sewage from collection and transmission to treatment, effectively overcoming the problems of complex rural terrain and scattered residences, greatly improving sewage collection efficiency, reducing manual operation and maintenance costs, and promoting rural sewage treatment towards intelligence and efficiency.

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail below.
[0028] Example: A smart siphon negative pressure collection system for rural sewage, referring to... Figure 1 , Figure 2 and Figure 4 The system includes a vacuum well 1, which is integrally molded from high-strength, corrosion-resistant engineering plastic material. The 2mm wall thickness has been mechanically calculated and tested to ensure structural strength while reducing overall weight, making it suitable for installation in complex rural terrain. The vacuum well 1 is equipped with a negative pressure collection mechanism 2, which is the core component for efficient sewage collection. It can quickly draw in sewage under negative pressure. The negative pressure collection mechanism 2 includes a connection interface 21, which is firmly fixed to the inside of the vacuum well 1 by a hot-melt process. Multiple arrayed connection interfaces 21 can connect multiple sewage pipes simultaneously, significantly improving sewage collection efficiency. Two toothed hangers 291 are arrayed at the top of the drainage pipe 26.
[0029] Specifically, when domestic sewage from farmers flows into vacuum well 1 through user drain pipe 28, as the sewage accumulates, it automatically opens when the water level reaches the set sensing height of vacuum valve 24. At this time, under the negative pressure environment created by the negative pressure power center, the sewage flows rapidly into drainage pipe 26 through inlet pipe 27, and is then pumped to the municipal pipe network or purification facilities through negative pressure collection pipe. During this process, ball valve 22 can be quickly closed manually or remotely to cut off the water flow as needed for inspection or maintenance, facilitating safe operation by staff. Overflow pipe 25 monitors the water level in vacuum well 1 in real time. If a system malfunction causes the sewage to exceed the normal capacity, the excess sewage can be discharged in time to prevent sewage from overflowing from vacuum well 1 and polluting the environment. The central control column connection port 23 continuously interacts with the system control center to achieve remote monitoring and intelligent control of the entire collection process, ensuring efficient and stable sewage collection.
[0030] A drainage pipe 26 is fixedly connected inside the vacuum well 1. The drainage pipe 26 is made of anti-aging and acid-alkali resistant PVC material to ensure long-term use without damage. A ball valve 22 is fixedly connected externally to the drainage pipe 26. The ball valve 22 can be quickly opened and closed manually or remotely, facilitating system inspection and maintenance. A vacuum valve 24 is fixedly connected to the top of the drainage pipe 26. As a key control component, the vacuum valve 24 can accurately sense the sewage level in the vacuum well 1 and automatically open when the set amount is reached, initiating the negative pressure suction process. A water inlet pipe 27 is installed at the bottom of the drainage pipe 26. The diameter of the water inlet pipe 27 has been optimized through flow calculation to ensure that sewage can quickly flow into the drainage pipe 26. A valve is installed at the top of the drainage pipe 26. The fixing component 29 is used to firmly support the drainage pipe 26 and prevent it from shaking during negative pressure suction. The vacuum well 1 is externally fixedly connected to the central control column connector 23, which is used to connect to the system control center to realize data transmission and remote control. The front end of the drainage pipe 26 is fixedly connected to the overflow pipe 25. The overflow pipe 25 is designed as a safety redundancy to discharge sewage in time when the system failure causes excessive sewage, thus preventing the vacuum well 1 from overflowing. The drainage pipe 26 is externally fixedly connected to the user drainage pipe 28, which is responsible for connecting the domestic sewage generated by farmers and introducing it into the collection system. The external sliding connection of the drainage pipe 26 is inside the vacuum well 1, which improves the installation efficiency.
[0031] Specifically, the toothed hanger 291 is tightly fixed to the top of the drainage pipe 26 with high-strength bolts, providing strong support for the drainage pipe 26 from the vertical direction. This effectively counteracts the tension generated during negative pressure suction, preventing the drainage pipe 26 from shaking, shifting, or even falling off due to uneven force, and ensuring the smooth transport of sewage within the pipe. The wall-mounted bracket 292 is firmly installed on the wall or other support using expansion bolts, firmly fixing the vacuum well 1 and enhancing its stability in complex terrain or harsh environments. This prevents factors such as ground subsidence and external impacts from affecting the normal operation of the system. Meanwhile, the multiple arrayed connection interfaces 21 are tightly integrated with the vacuum well 1 using a hot-melt process, allowing simultaneous connection to multiple sewage pipes. This greatly improves the system's ability to collect sewage from scattered rural households, flexibly adapting to both single-family courtyards and concentrated villages, and significantly increasing the coverage rate of rural sewage collection.
[0032] Reference Figure 1 and Figure 3The fixing component 29 includes a toothed hanger 291, the bottom end of which is fixedly connected to the top of the drainage pipe 26 by a high-strength bolt, providing vertical support for the drainage pipe 26. The vacuum well 1 is externally fixedly connected to a wall mount 292, which is fixed by expansion bolts, so that the vacuum well 1 can be firmly installed on the wall or other support, enhancing the stability of the system. The wall thickness of the vacuum well 1 is 2mm. This thickness design takes into account both strength and cost, ensuring the pressure bearing capacity of the vacuum well 1 while reducing material costs. The vacuum well 1 has multiple connection interfaces 21 arranged in an internal array. This design allows the system to be flexibly connected to sewage pipes in different areas, adapting to the characteristics of rural decentralized residences.
[0033] Specifically, the 2mm thick vacuum well 1, made of high-strength, corrosion-resistant engineering plastic, effectively reduces its weight while meeting the requirements for pressure resistance and corrosion resistance, thus lowering the difficulty of transportation and installation. It is especially suitable for rural environments with complex terrain and inconvenient transportation. Its unique one-piece molding process reduces splicing gaps, further improving sealing and preventing sewage leakage that could pollute the soil and groundwater. The multiple connection interfaces 21 arranged in an internal array act like "collection ports," efficiently gathering sewage pipes from different areas. This breaks the limitations of scattered rural households and fragmented sewage collection points, making the entire collection system like a flexible "network" that can be expanded or adjusted at any time according to actual needs. This greatly enhances the system's practicality and adaptability, providing a reliable hardware foundation for rural sewage treatment.
[0034] Working principle: When the intelligent siphon negative pressure collection system is working, the sewage that flows by gravity from various places first flows into the negative pressure intelligent collector, i.e., vacuum well 1. When the sewage in vacuum well 1 reaches a certain amount, the vacuum valve 24 in the negative pressure collection mechanism 2 opens. At this time, due to the negative pressure environment provided by the negative pressure power center, under the action of negative pressure suction, the sewage is drawn into the negative pressure collection pipe at high speed through the inlet water pipe 27, the drainage pipe 26, and the user drainage pipe 28. The negative pressure power center serves as the power source of the system. Its internal negative pressure collection tank, negative pressure generation system, and negative pressure sewage discharge system work together to transport the sewage collected by the negative pressure collection pipe to the municipal pipe network or purification treatment facilities. Its control system adopts the form of a PLC touch screen, which has automatic or manual switching function and can flexibly control the system operation.
[0035] During system operation, the fault monitoring section plays a crucial role. Through IoT and internet technologies, it monitors the equipment within the negative pressure power center in the service area in real time. Upon detecting a fault, it automatically alarms, intelligently determines the fault type, and pushes relevant information to the user's mobile phone via SMS. Simultaneously, it achieves intelligent fault location, remotely controls equipment start-up or shutdown, and regularly generates equipment operation reports. This provides multi-dimensional information management encompassing projects, equipment, areas, and maintenance, ensuring normal system operation. Faults are handled promptly according to a multi-level emergency response process, and complete data is recorded during the handling process. Furthermore, the vacuum well 1 has a 2mm wall thickness and multiple internal array connection interfaces 21, which, combined with the fixing components 29 for stable support, enable the system to adapt to complex rural terrain or environments with high groundwater levels. This effectively prevents pipe network leakage, significantly improves rural sewage collection rates, and achieves intelligent sewage collection and treatment operations.
