Description

Technical Field

[0001] This invention relates to a buried pumping station, specifically to a prefabricated, heavy-duty, highly reliable, and vehicle-accessible smart buried pumping station that is easy to install, has high strength, small footprint, and high level of intelligence, as well as a control method for the smart buried pumping station. Background Technology

[0002] Currently, underground pumping stations are mainly divided into two categories: traditional concrete pumping stations and integrated prefabricated pumping stations. Traditional concrete pumping stations have strong load-bearing capacity, but they have long construction cycles, large footprints, are inconvenient to assemble and disassemble, have high construction costs, and the concrete material is prone to corrosion, leakage, and high water absorption, making them unsuitable for special water storage scenarios. Integrated prefabricated pumping stations mostly use fiberglass, stainless steel pipes, or single-material water tanks, which have the advantages of prefabricated installation, high construction efficiency, and compact structure, but have significant technical shortcomings. Both types of pumping stations are used in municipal, residential, and industrial scenarios, but due to limitations in material properties, structural design, and construction technology, they have many insurmountable technical shortcomings.

[0003] I. Insufficient load-bearing capacity and poor adaptability: Traditional concrete pump station roofs are mostly simple cast-in-place structures without a dedicated support system, making them prone to cracking and settlement under long-term vehicle pressure; integrated precast pump station cylinders are mostly thin-walled structures, and their load-bearing capacity after being covered with soil is generally ≤100kN / m. 2 It can only withstand pedestrians or planted greenery, and cannot meet the passage requirements of 40-ton vehicles on municipal roads and main roads in residential areas, thus strictly limiting its application scenarios; although some pump stations have tried to thicken the top plate, it has led to a sharp increase in self-weight, increased construction difficulty, and easy stress concentration damage.

[0004] Second, significant shortcomings in material performance: The concrete substrate of traditional concrete pump stations has high porosity and a water absorption rate of ≥3%. When in contact with sewage, acid and alkaline wastewater for a long time, it is prone to corrosion and carbonization, which not only affects the structural strength but also leads to secondary water pollution. It is unsuitable for scenarios with requirements for material safety, such as water supply and storage and food processing. The fiberglass material commonly used in integrated prefabricated pump stations has poor impact resistance and is prone to cracking under long-term soil pressure or slight collisions. Ordinary composite plastics have insufficient strength, and metal materials are prone to corrosion. Moreover, neither of these materials can meet the diverse requirements of "high strength + corrosion resistance + food grade" at the same time. Third, frequent sealing and leakage problems and difficult maintenance: Traditional concrete pump stations often use waterstops to seal construction joints and expansion joints, which are prone to failure due to concrete shrinkage and foundation settlement, resulting in leakage rates of over 30%; the modular splicing joints of integrated prefabricated pump stations rely on rubber sealing rings for sealing. Rubber is prone to aging, hardening, and cracking in the damp underground environment, and usually needs to be replaced every 3-5 years. Moreover, the seals are embedded inside the splicing gaps, and replacement requires disassembling the pump station modules, which is difficult and costly. Some old pump stations cannot be repaired due to sealing failure and can only be scrapped as a whole; In addition, the sealing design of cable outlets, pipe interfaces and other details of both types of pump stations is rudimentary and can easily become potential leakage points.

[0005] IV. Long construction period and high cost: Traditional concrete pumping stations require multiple stages such as foundation pit excavation, rebar binding, formwork, pouring, and curing. The curing period is ≥28 days, and the overall construction period is as long as 1-3 months. It is greatly affected by the weather, and there is a large demand for on-site construction personnel, resulting in high labor costs.

[0006] V. Insufficient scalability and environmental friendliness: Traditional concrete pump stations are integral cast-in-place structures that cannot expand their volume according to changes in water volume. If expansion is required later, excavation and reconstruction are necessary, resulting in serious waste of resources. Although integrated prefabricated pump stations have a modular structure, the module specifications are fixed, and the splicing compatibility is poor. When expanding, the original modules need to be replaced, which is costly. At the same time, traditional concrete pump stations generate a large amount of construction waste when demolished, and the fiberglass, rubber and other materials of integrated prefabricated pump stations are difficult to recycle, resulting in poor environmental friendliness. Summary of the Invention

[0018] In a specific embodiment of the present invention, the pump unit serves as a water supply pumping station, and the pump unit includes a high-efficiency silent water supply device, a stainless steel water tank, and control equipment.

[0019] In a specific implementation of the present invention, the equipment in the pump room is equipped with an intelligent monitoring unit, which detects the water level in the pool and the core parameters of the equipment, such as pressure, flow rate, temperature, and current.

[0020] A control method for a smart underground pumping station includes the following steps: After system initialization, pressure, flow rate, liquid level, and temperature and humidity data are collected in real time through multiple sensors, and combined with preset parameter thresholds, the data is processed by an IoT centralized control cabinet; the processed data is transmitted to the IoT smart platform and the pumping station data monitoring center respectively; at the same time, the control cabinet stores and records the relevant data locally, and performs regular automatic inspections to detect the reliability of the equipment. On the intelligent platform side, a comprehensive status assessment of the data is conducted: when the data is normal, the system continuously monitors in real time and generates regular maintenance suggestions; when the data is abnormal, the system issues potential risk warnings or fault alarms, and records the warning events and fault events respectively; when the system experiences an abnormal fault, the system issues a fault alarm notification to remind managers and records the corresponding data; the platform analyzes historical and real-time data to generate suggestion reports containing optimization strategies, assisting managers in adjusting control parameters and operation and maintenance strategies to form a closed-loop control.

Detailed Implementation

[0035] The preferred embodiments of the present invention are given below with reference to the accompanying drawings to illustrate the technical solution of the present invention in detail.

[0036] Figure 1 This is a schematic diagram of the overall structure of the underground pumping station provided by the present invention. Figure 2 This is a schematic diagram of the internal structure of the underground pumping station provided by the present invention. Figure 3 A top view of the underground pumping station provided by the present invention, as shown below. Figure 1-3 As shown: The present invention proposes a prefabricated, heavy-duty, highly reliable, vehicle-accessible smart underground pumping station, which includes: a modular prefabricated water tank 1, a modular prefabricated pump house 2, a heavy-duty roof plate assembly 3, a heavy-duty support assembly 4, a sealing and seepage prevention system 5, a pump unit 6, and an intelligent monitoring unit 7.

[0037] Both the modular assembled water tank 1 and the modular assembled pump house 2 adopt a separate structure, which is composed of several prefabricated composite panels 11 assembled together.

[0038] The heavy-duty top plate assembly 3 covers the top of the modular assembled water tank 1 and the modular assembled pump house 2. The heavy-duty support assembly 4 is the support frame for the modular assembled water tank 1 and the modular assembled pump house 2. The heavy-duty top plate assembly 3 is rigidly connected to the heavy-duty support assembly 4 below. The heavy-duty support assembly 4 adopts a portal frame structure, and the top of the heavy-duty support assembly 4 is connected to the heavy-duty top plate assembly 3.

[0039] Pump unit 6 is located inside modular assembled pump house 2, while intelligent monitoring unit 7, used for real-time monitoring and remote control, is located outside modular assembled pump house 2.

[0040] The sealing and seepage prevention system 5 in this invention (see Figure 9 and 10 The system is made of three layers of sealing and waterproofing process. The right-angle inside corners of the wall panels and the bottom of the corrugated part are sealed with sealant at the right-angle inside corners of the two legs of the doorposts at the bottom of the corrugated part ...

[0041] The sealing and seepage prevention system 5 employs a three-layer sealing and waterproofing process: sealant is applied to the right-angled inside corners and corrugated bottoms of the wall panels 52, to the right-angled inside corners of the doorposts 51, and to the joints between wall panels 53. All wall panel joints are connected using hot-melt welding. This novel sealing and waterproofing method ensures a tight seal and extends the service life to up to 50 years, a feature not found in other fire pump stations. Furthermore, comprehensive waterproofing is applied after installation, further enhancing waterproofing performance and achieving a leak-proof standard for 50 years. This also reduces the cost of periodically waterproofing traditional concrete water tanks.

[0042] The pump unit 6 in this invention is one or a combination of several of the following: a fire pump station, a rainwater pump station, or a water supply pump station. If used as a fire pump station, pump unit 6 mainly consists of a highly integrated skid-mounted IoT unit, a multi-functional integrated control cabinet, and fire-fighting pressure stabilizing equipment. If used as a rainwater pump station, pump unit 6 mainly consists of a drainage pump, a sewage pump, and control equipment. If used as a water supply pump station, pump unit 6 mainly consists of a high-efficiency, quiet water supply equipment, a stainless steel water tank, and control equipment. This advantage makes it suitable for urban renewal, fire protection system renovation, water supply renovation in old residential areas, rainwater harvesting, sewage treatment, industrial parks, and other water supply and drainage scenarios requiring underground installation and bearing the load of ground vehicles. It is particularly suitable for water storage scenarios requiring corrosion resistance and food-grade safety of the materials, demonstrating strong adaptability.

[0043] Modular assembled water tank 1 and modular assembled pump house 2 are both assembled on site from prefabricated composite panels 11. The side wall panels are fastened together by pre-embedded bolt holes. The strong sealing is achieved by combining three-layer sealing and waterproofing process and high-density resin hot-melt connection at the joints between the panels. The internal structure is supported by load-bearing columns, and the top plate is made of cast-in-place concrete with steel bars tied in molds.

[0044] The modular prefabricated water tank 1 and modular prefabricated pump house 2 are internally equipped with prefabricated heavy-duty support components 4 (see...). Figure 7 It is mainly composed of precast C35 concrete portal frame load-bearing beams and columns 41, assembled using mortise and tenon joints, with auxiliary metal connectors 42 for assembly and positioning. Each load-bearing beam and column contains grade III steel and densely packed stirrups, which not only improves the stability of the supporting structure but also enhances construction precision, significantly shortens the construction period, and reduces construction costs.

[0045] The top of the water tank and pump room is a heavy-duty roof slab assembly 3 (see Figure 8 It mainly consists of two parts: galvanized truss plate 31 and cast-in-place C35 concrete 32. The heavy-duty roof plate assembly 3 is connected to the concrete portal frame load-bearing beam column 41 via roof plate connecting bolts 33, and to the side plates of the precast composite panel 11 via side plate connecting bolts 34. Using galvanized truss plate as the casting mold, different reinforcement is tied internally according to the load-bearing capacity, and C35 concrete is poured on-site. This technology allows heavy-duty vehicles to pass over the top of the pump station, a feature not found in pump stations made of other materials.

[0046] Precast composite panel 11 (see Figure 4 It is mainly composed of a water-facing surface, a structural layer, and a protective layer. The water-facing surface is made of high-density, rigid, corrosion-resistant resin 11 with anti-detachment anchor points. The structural layer consists of high-strength concrete 14 and high-density steel reinforcement 12 (see...). Figure 5 and 6 The precast composite panel 11 is composed of a protective layer 15, which can be coated with an outer layer of corrosion-resistant material or precast with high-density material to enhance the service life and aesthetics of the pool. Therefore, the precast composite panel 11 has the excellent load-bearing capacity, seismic resistance, and fire resistance of reinforced concrete, as well as the acid and alkali corrosion resistance, seepage prevention, low water absorption, antibacterial and wear-resistant properties of high-density resin. The inner wall of the precast composite panel 11 in contact with water is made of high-density hard corrosion-resistant resin material with anti-detachment anchor points. Compared with traditional concrete, it is not easy for microorganisms to grow. The high-density hard corrosion-resistant resin 11 on the water-facing side has added anti-detachment anchor points, which increases the tensile strength of the precast composite panel and extends the service life.

[0047] A new type of sealing structure is adopted between the precast composite panel 11 and the panel and the portal beam column. It is mainly composed of special connectors embedded on the side of the side wall panel and the portal beam column, which are fastened together by high-strength bolts. Combined with three-layer sealing and waterproofing process and high-density resin hot-melt connection at the joint between the panel and the wall, a strong sealing structure is completed. The first layer of waterproofing involves applying expanding sealant along the right-angled inside corners of the wall panels, the bottom of the corrugations, the right-angled inside corners of the two legs of the doorposts, and at the screw connection holes of the embedded part 16. The second layer of waterproofing involves applying polysulfide sealant at the joints between wall panels, the joints between right-angled wall panels, and before the reinforcing connectors. The third layer of waterproofing involves using a hot air welding machine to heat-melt the joints between the side wall panels and the two legs of the door-shaped beams and columns to ensure the overall structural airtightness of the water tank. Waterproof coating is also applied to the secondary pouring joints of the water tank, the joints between the high-density resin board and the concrete, the joints of the doorposts, the secondary pouring joints on the side of the pump room, the outer joints of the wall panels, and the entire top surface, extending 30cm downwards. Unlike traditional fire pump stations where leakage in one section requires extensive earthwork and complete waterproofing of the entire water tank, the prefabricated, heavy-duty, highly reliable, and vehicle-accessible smart underground pump station provided by this invention features a three-layer waterproofing process that ensures the overall structural airtightness and extends service life. Furthermore, it employs intelligent water level monitoring, which can provide timely warnings and rapid repairs for leaks—features not found in pump stations constructed with other materials.

[0048] The pump room equipment is equipped with an intelligent monitoring unit 7, which can achieve a high degree of intelligence by detecting core parameters such as water tank level, equipment pressure, flow rate, temperature, and current. It enables real-time monitoring, automatic recording of operating data, automatic equipment inspection, and generation of maintenance suggestions, achieving the goals of early warning, in-process handling, and post-event analysis. This improves the automation and intelligence of the water system, eliminates potential equipment hazards, and makes the entire building's water system safer.

[0049] This invention provides a prefabricated, heavy-duty, highly reliable, and vehicle-accessible intelligent underground pumping station. The pump house incorporates intelligent dehumidification and insulation devices, ensuring a suitable environment through temperature and humidity monitoring. The equipment within the pump house utilizes a highly integrated control system, including units and a four-in-one control cabinet, effectively reducing the footprint and thus minimizing equipment space and costs. The water system equipment, coupled with an IoT platform, achieves high levels of intelligence, enabling real-time monitoring, automatic recording of operational data, automatic equipment inspection, and maintenance suggestion generation. This achieves pre-emptive warnings, in-process handling, and post-event analysis, improving system automation and intelligence, eliminating potential equipment hazards, and enhancing the safety of the entire building's water system.

[0050] Figure 11 For example, a flowchart of intelligent control functions, such as Figure 11As shown, this invention proposes a smart control method, comprising the following steps: After system initialization, pressure, flow rate, liquid level, and temperature and humidity data are collected in real time through multiple sensors. Combined with preset parameter thresholds, the data is processed by an IoT centralized control cabinet. The processed data is transmitted to both the IoT smart platform and the pump station data monitoring center. Simultaneously, the control cabinet locally stores and records the relevant data and performs periodic automatic inspections to check equipment reliability.

[0051] On the intelligent platform side, a comprehensive status assessment of the data is performed: when the data is normal, the system continuously monitors in real time and generates regular maintenance suggestions; when the data is abnormal, the system issues potential risk warnings or fault alarms, recording the warning events and fault events respectively; when the system experiences an abnormal fault, the system issues a fault alarm notification, reminding managers and recording the corresponding data. The platform analyzes historical and real-time data to generate suggestion reports containing optimization strategies, assisting managers in adjusting control parameters and operation and maintenance strategies to form a closed-loop control.

[0052] This invention is assembled on-site from precast concrete composite high-density resin composite panels, featuring high strength, vehicular accessibility, excellent sealing performance, short construction period, and low cost. Simultaneously, the intelligent monitoring unit enables remote monitoring and unattended operation. It is suitable for water supply and drainage markets requiring underground vehicle access, such as urban renewal, renovation of old residential areas, rainwater harvesting, sewage treatment, and industrial parks.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as defined by the appended claims and their equivalents.
