Description

Technical Field

[0001] This invention relates to the field of water supply network monitoring and control technology, specifically to a leakage detection device for water supply networks. Background Technology

[0002] As a core component of urban infrastructure, water supply networks bear the crucial responsibility of delivering water resources for residents' lives, industrial production, and public services. Their operational safety directly impacts the normal functioning of the city and the protection of people's livelihoods. However, the current operation and management of water supply networks face numerous pressing issues that need to be addressed: At the monitoring level, traditional systems often employ a combination of fixed-point manual inspections and distributed sensor monitoring, resulting in numerous monitoring blind spots and delayed data acquisition. Leaks in the pipeline network are often only detected after users report them or obvious water stains appear on the ground, leading to significant water waste. Statistics show that the leakage rate of urban water supply networks in my country generally exceeds 15%. Furthermore, the monitoring frequency of key indicators such as pipeline pressure and water quality parameters is low, and the data is fragmented, making it difficult to comprehensively reflect the operational status of the pipeline network.

[0003] In terms of data processing and analysis, existing systems can only achieve simple data storage and display, lacking the ability to deeply integrate and analyze multi-source data. Pipeline operation involves multi-dimensional data such as pressure, flow, water quality, pipeline topology, and geological environment. Traditional systems cannot establish the correlation between data, making it difficult to accurately identify potential pipeline hazards (such as pipeline corrosion, loose joints, etc.), let alone provide early warning of potential hazards.

[0004] At the level of control and emergency response, current control measures rely heavily on manual operation, resulting in slow response times. When emergencies such as pipe bursts or water pollution occur, maintenance personnel must rush to the scene to shut off valves and adjust water supply plans, often leading to prolonged water outages that disrupt residents' normal water use. Furthermore, emergency response lacks scientific data support, making it prone to decision-making errors and further amplifying the impact of the accident. Summary of the Invention

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figures 1-3 The diagram shows a leakage detection device for a water supply network, comprising: an inlet pipe 1, an outlet pipe 2, and a control box 3, wherein an inlet pressure transmitter 4 and an outlet pressure transmitter 5 are respectively installed on the inlet pipe 1 and the outlet pipe 2. It also includes: an electromagnetic flow meter 6 fixedly connected to one end of the water inlet pipe 1, the electromagnetic flow meter 6 being used to measure the water flow in the water inlet pipe 1, a flow regulating valve 7 fixedly connected to the end of the electromagnetic flow meter 6 away from the water inlet pipe 1, the flow regulating valve 7 being used to automatically adjust the opening degree according to the flow data detected by the electromagnetic flow meter 6, an electric gate valve 8 being provided at the end of the flow regulating valve 7 away from the electromagnetic flow meter 6, and the other end of the electric gate valve 8 being connected to the water outlet pipe 2; Specifically, by collecting flow data in the water supply network in real time through electromagnetic flowmeter 6, and combining the coordinated control of flow regulating valve 7 and electric gate valve 8, the water flow in the network can be dynamically adjusted, realizing continuous monitoring and precise control of the water supply system's operating status. By analyzing the difference between the flow change trend and the set threshold, the system can quickly identify abnormal flow, thereby effectively detecting and locating leakage in the network and improving the safety and operating efficiency of the water supply system.

[0022] The connecting end plates 9 are fixed at both ends of the electric gate valve 8. The connecting end plates 9 are circular and have multiple sets of connecting components 10 arranged in a ring array. A transmission component 11 is provided between the multiple sets of connecting components 10. The flow regulating valve 7 and the outlet pipe 2 are both fixed with connecting end plates 12 near the electric gate valve 8. The design of the connecting components 10 makes the assembly between the connecting end plates 9 and 12 more stable, and facilitates subsequent disassembly and maintenance operations.

[0023] In addition, the inlet pressure transmitter 4, outlet pressure transmitter 5, electromagnetic flowmeter 6, flow regulating valve 7, and electric gate valve 8 are all located in the control box 3. A controller 28 is installed on the front of the control box 3. The controller 28 is electrically connected to the inlet pressure transmitter 4, outlet pressure transmitter 5, electromagnetic flowmeter 6, flow regulating valve 7, and electric gate valve 8, respectively. The control box 3 provides a centralized management space for various devices. As the core component, the controller 28 can receive data from the inlet pressure transmitter 4, outlet pressure transmitter 5, and electromagnetic flowmeter 6, and accurately control the flow regulating valve 7 and electric gate valve 8 according to preset logic.

[0024] Furthermore, to further enhance the reliability of the device, an audible and visual alarm 29 is installed on the top of the control box 3. This alarm is connected to the controller 28 and can promptly issue an alarm signal when an abnormality is detected. In this way, maintenance personnel can quickly locate the problem and take corresponding measures to prevent leakage or other faults from escalating. At the same time, a cooling fan 30 is also equipped on the side of the control box 3 to ensure that the internal equipment operates within a suitable temperature range and extend its service life.

[0025] For further details, please refer to [link / reference]. Figure 3 and Figure 4 The connecting assembly 10 includes a limiting cylinder 13, a bearing 14 is sleeved on the outer side of the limiting cylinder 13, a rotating groove 15 is provided on the connecting end plate 9, the limiting cylinder 13 and the rotating groove 15 are clearance-fitted, the inner ring of the bearing 14 is fixedly connected to the connecting end plate 9, a gear 16 is fixedly connected to the outer ring of the bearing 23, the limiting cylinder 13 and the gear 16 are fixedly sleeved, a fixing bolt 17 is sleeved inside the limiting cylinder 13, a screw hole 18 adapted to the fixing bolt 17 is provided on the connecting end plate 12, and a clamping member 19 is fixed to the end of the fixing bolt 17 away from the screw hole 18; Additionally, see Figure 6 The transmission assembly 11 includes a slewing bearing 20, which is fixedly sleeved on the end of the electric gate valve 8. A gear ring 21 is rotatably connected to the outer side of the slewing bearing 20, and the gear ring 21 meshes with the gear 16.

[0026] Specifically, when installing the electric gate valve 8, align the connecting end plates 9 and 12 at both ends of the electric gate valve 8, and align the multiple screw holes 18 with the corresponding fixing bolts 17. Then, by rotating the gear 16, the gear 16 drives the limiting cylinder 13 to rotate, which in turn drives the fixing bolts 17 inside to move axially. Under the pressure of the clamping member 19, the fixing bolts 17 rotate and move, and are screwed into the screw holes 18, thus fixing the electric gate valve 8. Simultaneously, the rotation of one of the gears 16 also drives the gear ring 21 to rotate, which in turn drives the other gears 16 to rotate together, ultimately causing all the fixing bolts 17 to move synchronously and be screwed into the corresponding screw holes 18. This achieves rapid installation of the electric gate valve 8, improving installation efficiency and ensuring connection stability. Through the meshing transmission between the gear 16 and the gear ring 21, all fixing bolts 17 can move synchronously, avoiding loosening caused by uneven tightening of individual bolts.

[0027] It should be noted that during disassembly or maintenance, simply rotating gear 16 in the reverse direction will allow the fixing bolts 17 to be removed synchronously, thereby quickly separating the electric gate valve 8 from the connecting end plate 12. This design greatly simplifies the maintenance process, reduces the complexity of manual operation, and also reduces equipment downtime, providing a strong guarantee for the efficient operation of the water supply network.

[0028] It should be noted that, for reference Figure 7 The inner side of the limiting cylinder 13 is provided with a limiting groove 27, and the end of the fixing bolt 17 is slidably connected to the limiting groove 27, which effectively prevents the fixing bolt 17 from shifting during rotation, thereby further improving the assembly accuracy.

[0029] For further details, please refer to [link / reference]. Figure 4 To facilitate adjustment of the gears 16 by operators, one of the gears 16 is equipped with an internal hexagon block 26. The internal hexagon block 26 not only improves operational convenience but also effectively transmits torque, ensuring the gear 16 remains stable during rotation. Furthermore, the use of the internal hexagon block 26 in conjunction with an adjustable wrench reduces reliance on specialized tools, thereby lowering maintenance costs and operational difficulty.

[0030] Example 2 Please see Figure 5 This embodiment further illustrates Example 1, with the difference being the optimization of the limiting cylinder 13.

[0031] Specifically, the clamping member 19 includes a pressure rod 22 fixedly connected to the end of the fixing bolt 17. A bearing 23 is fixedly sleeved at the end of the pressure rod 22 away from the fixing bolt 17. A piston block 24 is fixedly sleeved on the outer ring of the bearing 23. An injection cylinder 25 is fixedly sleeved at the end of the limiting cylinder 13 away from the connecting end plate 9. The piston block 24 and the injection cylinder 25 are sealed together. The injection cylinder 25 is made of transparent material, and scale markings are provided on the outer side of the injection cylinder 25.

[0032] Specifically, the design of the syringe 25, with its transparent material and graduated markings, allows operators to directly observe the movement of the piston block 24. When the fixing bolt 17 loosens due to vibration or external force, the change in position of the piston block 24 is directly reflected on the graduations of the syringe 25, helping operators quickly determine whether the connection is normal. This not only improves operational accuracy but also avoids connection problems caused by over-tightening or under-tightening. Furthermore, the sealed connection between the syringe 25 and the piston block 24 ensures the stability of the internal structure, preventing external impurities from affecting the normal operation of the equipment.

[0033] It should be noted that when the fixing bolt 17 is fully tightened, the piston block 24 will reach the predetermined position of the syringe 25. At this time, the scale markings on the syringe 25 can be used as a reference to confirm whether the installation is in place. If the piston block 24 does not reach the designated position, it indicates that the fixing bolt 17 may be loose or there may be other abnormalities, reminding the operator to make timely adjustments.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
