Description

Technical Field

[0001] This application relates to the field of measurement equipment technology, and in particular to a highly flexible fluid pipeline impedance measurement device. Background Technology

[0002] Fluid piping systems are widely used in numerous industrial sectors, such as petrochemicals, aerospace, biomedicine, and HVAC. When fluids flow through these pipes, the impedance characteristics of the piping have a crucial impact on the performance, energy consumption, and stability of the entire system. Accurate measurement of the impedance of fluid piping is of paramount importance for optimizing system design, fault diagnosis, and ensuring efficient and reliable system operation.

[0003] Traditional methods and devices for measuring fluid pipeline impedance often have numerous limitations. Some early measurement techniques relied on complex and fixed experimental equipment, which was typically bulky, inconvenient to install, and difficult to adapt to different site environments and pipeline layouts. For example, some measurement systems based on large hydraulic test benches were not only expensive to build but also required dedicated sites and numerous auxiliary facilities, making them inflexible for moving to different pipeline installation locations for testing. Furthermore, some traditional measuring devices have strict requirements for specific fluid types or pipeline sizes, lacking versatility. For instance, some measuring instruments designed specifically for metal pipes of a certain diameter cannot accurately measure the impedance of plastic pipes or pipes with significantly different diameters, limiting their application in diverse pipeline systems. As modern industry develops towards intelligence, diversification, and distribution, there is an urgent need for a new type of device that is highly flexible, widely applicable, easy to operate, and capable of accurately measuring fluid pipeline impedance.

[0004] A search revealed Chinese Patent Publication No. CN211927949U, which discloses a gas velocity measuring device for a dust-laden gas pipeline. The device includes a cylindrical velocimeter perpendicular to the gas pipeline, a pressure measuring device one, and a pressure measuring device two. The velocimeter has a central hole and a lateral hole on its side wall. The central hole and the lateral hole are at the same height, and their axes both point towards the axis of the velocimeter. The central hole faces the flow direction of the gas to be measured. The pressure measuring device one is connected to the central hole via a gas pipeline one, and the pressure measuring device two is connected to the lateral hole via a gas pipeline two. The gas pipeline one and the gas pipeline two are connected in parallel. This device can perform online measurements without response time, eliminating the need for manual measurement using devices such as pitot tubes. Even if dust enters the two throttling devices, causing a change in the impedance coefficient, the measurement result is not affected because the absence of gas flow is determined by differential pressure, resulting in high measurement accuracy.

[0005] Regarding the aforementioned technologies, the inventors discovered the following shortcomings: Lack of adaptability to complex pipe fittings: T-junctions have three inlets with different flow directions, resulting in a complex structure with varying angular relationships between the inlets and fluid convergence and divergence. The current device's design is clearly geared towards single-shaped pipes and does not consider how to securely install it on different sections of the tee. For example, it cannot simultaneously acquire accurate pressure data from different flow direction sections and ensure the sealing and stability of the connection between the device and the tee, making it difficult to effectively perform impedance measurements in such common and critical pipe structures as tee junctions. Right-angle pipes exhibit unique fluid dynamics at bends, where the pressure and velocity distribution of the fluid changes significantly. However, existing devices, designed for single-shaped pipes, lack specialized clamping and fixing structures for right-angle bends, making it difficult to accurately install sensors and other key measuring components in suitable positions to precisely capture pressure differences before and after the bend, thus hindering accurate impedance measurement of right-angle pipes.

[0006] Furthermore, in actual industrial settings, it is often necessary to quickly install measuring devices onto corresponding pipelines for measurement work, and then quickly disassemble them for transfer to the next pipeline after the measurement is completed. However, the fixing structure of this device is relatively fixed and does not reflect the convenience of quick clamping and disassembly. For example, it may lack convenient clamping mechanisms such as simple snap-fit, plug-in, or quick bolt connections, and instead requires complex tools or cumbersome procedures to complete the installation and fixing. This undoubtedly greatly increases the time and labor costs of on-site operations and reduces work efficiency, especially when the measurement location and pipeline need to be changed frequently, this inconvenience is even more obvious.

[0021] Pipe clamps: Used to clamp the ports of the first and second pipes under test. They need to possess good clamping force and stability, be adaptable to pipes of different diameters, and not damage the pipes during clamping, ensuring the pipes' sealing and integrity. Their clamping surfaces are made of rubber or soft materials, ensuring a firm clamping fit without damaging the pipes under test. As a critical component in direct contact with the pipes under test, the precise clamping performance of the pipe clamp is essential for obtaining accurate measurement data. By stably clamping the pipes, it ensures stable fluid conduction between the pipes and the device during measurement, preventing pressure measurements from being affected by leaks or poor connections, thus ensuring the accuracy of impedance calculations.

[0028] In summary, this application includes the following beneficial technical effects:

[0029] 1. This utility model demonstrates excellent pipeline adaptability through the ingenious design of its pipeline clamping and adjustment components. The pipeline clamps in the components can accommodate the ports of both the first and second pipelines under test with different diameters. Their excellent clamping force and stability, along with the use of rubber or soft materials for the clamping surfaces, ensure a secure grip on the pipeline while preventing damage, thus guaranteeing the pipeline's sealing and integrity. This allows for the effective connection of fluid pipelines of both conventional and special diameters. Furthermore, the number of pipeline clamping and adjustment components can be flexibly adjusted according to the number of ports in the first pipeline under test. Whether it's a simple straight pipe with a single port or a complex pipeline with multiple ports like a tee, the corresponding number of components can be used for clamping and measurement. Furthermore, the sliding connection design between the arc-shaped slider at the bottom of the first slider and the second annular slide rail, as well as between the bottom of the second slider and the first annular slide rail, allows for flexible adjustment of the angle and position of the pipe clamping and adjustment components. This addresses the challenges of varying pipe port curvature or different installation angles, such as the measurement needs of curved pipes and various complex pipe layouts. This broad adaptability to different pipe diameters, number of ports, and pipe shapes significantly expands the device's application range, enabling it to perform impedance measurement in numerous different types of fluid pipeline systems. This reduces the cost and time associated with replacing measuring equipment due to differences in pipe structure, and improves the versatility and convenience of fluid pipeline impedance measurement in industrial production.

[0030] 2. The internal structural design of the device provides strong support for accurate measurement and stable operation. The RS pressure testing device inside the pressure testing chamber can accurately detect pressure conditions and, through wireless communication with the data processing and communication unit, quickly transmit the data to the appropriate data processing unit for subsequent analysis and processing, ensuring the accuracy and timeliness of pressure data acquisition and laying the foundation for accurate calculation of fluid pipeline impedance. In the clamping section, the servo motor serves as the control source for the clamping action, precisely controlling the clamping force and movement of the pipeline clamp according to different pipeline characteristics and measurement requirements. This effectively avoids pipeline leakage or damage caused by improper clamping, ensuring the stability of fluid conduction during the measurement process, thereby guaranteeing the reliability of the measurement data. Furthermore, the bearing housing's support and positioning of related transmission components, along with the auxiliary functions of components such as the pointer and the first pressure adapter plate, ensure that all components maintain accurate positional relationships during operation. This stable operation of the mechanical transmission structure effectively avoids measurement errors or clamping failures caused by component displacement or shaking, guaranteeing the accuracy and stability of the entire process from clamping the pipeline under test to data acquisition and processing. This provides solid technical support for the high-precision requirements of fluid pipeline impedance measurement in industrial production and helps improve the accuracy of fluid pipeline system performance evaluation and fault diagnosis.

[0038] The following is in conjunction with the appendix Figure 1 —6 provides further details regarding this application.

[0039] This application discloses a highly flexible fluid pipeline impedance measurement device.

[0040] like Figure 1As shown, a highly flexible fluid pipeline impedance measuring device includes a base 1. The base 1 serves as the fundamental support structure for the entire device and must possess sufficient strength and stability. It is typically made of metal materials such as aluminum alloy or steel to support other components of the device and ensure that it does not deform or shake significantly during measurement. Symmetrical movable slots 2 are provided on both sides of its top. These slots provide adjustable space for the subsequent installation of the pressure detection chamber 3, allowing the chamber to move within a certain range to adapt to different measurement needs and pipeline layouts.

[0041] The pressure detection chamber 3 is movably installed inside the movable tank 2. Inside the pressure detection chamber 3 is a pressure testing device, model R2008S, renowned for its high precision and stability, capable of accurately sensing minute changes in fluid pressure. Its working principle is based on pressure sensor technology; when fluid pressure acts on the sensor's sensitive element, it causes a change in electrical signal. The built-in signal processing circuit converts this electrical signal into identifiable pressure data. Pressure transmission pipes 4 are symmetrically arranged on the left and right sides of the pressure detection chamber 3. These pipes are made of high-pressure resistant and well-sealed materials, such as stainless steel or special engineering plastics. Their function is to transmit the pressure in the pipeline under test to the pressure testing device inside the pressure detection chamber 3, ensuring accurate acquisition and transmission of pressure data.

[0042] A testing platform 5 is mounted on the top of the base 1. The testing platform 5 provides the mounting foundation for the pipe clamping and adjustment assembly 7 and related connecting parts, and its structure ensures the relative positional accuracy between the components, facilitating precise measurement operations. The testing platform 5 includes a connecting frame body 501, an auxiliary slot 502, a first annular slide rail 503, a second annular slide rail 504, and a first helical gear 505. The connecting frame body 501 is fixedly mounted on the top of the base 1, serving as the main framework of the testing platform 5 and bearing the responsibility of connecting and supporting other components. Its structural design must consider the overall mechanical performance and stability. The top of the connecting frame body 501 has an auxiliary slot 502, which can be used for wiring, installing small accessories, or as a positioning reference for certain components, playing an auxiliary role in the assembly and debugging of the device. The top of the connecting frame body 501 is provided with a first annular slide rail 503 and a second annular slide rail 504. These two annular slide rails provide precise sliding tracks for the subsequent slider components, enabling the relevant components to move smoothly along a specific trajectory, which is crucial for adjusting the pipe clamping angle and position. The first helical gear 505 is fixedly installed on the top of the connecting frame body 501. Its meshing transmission relationship with other gear components plays a key role in the motion control of the pipe clamping and adjustment assembly 7. Through cooperation with other gears, it realizes the transmission of power and the conversion of the direction of movement.

[0043] The number of pipe clamping and adjustment components 7 is the same as the number of ports of the first test pipe 8 that needs to be tested for resistance. This design ensures that each test pipe port has a corresponding clamping and adjustment component for precise operation. The ports of both the first test pipe 8 and the second test pipe 9 are clamped by pipe clamps 719. The inner diameters of the first test pipe 8 and the second test pipe 9 are the same as the inner diameter of the fluid connecting pipe 713. This design ensures smooth fluid conduction between the pipe and the device during measurement, reducing pressure loss or flow rate changes caused by differences in pipe diameter. The ports of both the first test pipe 8 and the second test pipe 9 are connected to the fluid connecting pipe 713 via a second pressure adapter plate 714. The second pressure adapter plate 714 acts as a transition connection, and its connection points with the pipe ports and the fluid connecting pipe 713 are sealed using a sealing design, such as rubber gaskets or special sealing structures, to prevent fluid leakage and thus ensure the accuracy of pressure data during measurement. The pressure transmission pipe 4 is fixedly installed to the first pressure adapter plate 712 through a hose, and the hose is connected to the fluid communication pipe 713 through the first pressure adapter plate 712. The use of the hose provides a certain degree of flexible connection, which can adapt to the slight displacement and deformation of the device under different working conditions. At the same time, the first pressure adapter plate 712 plays the role of integration and transfer in the pressure transmission link, ensuring that the pressure can be stably transmitted between different components.

[0044] The pressure testing chamber 3 is wirelessly connected to the data processing and communication unit 6. This wireless communication method employs advanced wireless transmission technologies, such as Bluetooth or Wi-Fi modules, ensuring that the pressure data collected by the pressure testing chamber 3 can be transmitted to the data processing and communication unit 6 in a timely and accurate manner. The data processing and communication unit 6, as the core data processing center of the device, is typically composed of a high-performance microprocessor or computer, possessing powerful data processing capabilities and rich communication interfaces. It can process the received pressure data in real time, calculate the impedance value of the fluid pipeline according to a preset algorithm, and store, display, and interact with other external devices through a network interface, realizing intelligent monitoring and management of the entire fluid pipeline system.

The mounting rod 702 is fixedly installed on the top of the connecting frame body 501, providing vertical support and positioning for the entire pipeline clamping and adjustment assembly 7. Its installation position and verticality need to be precisely controlled to ensure the installation accuracy and smooth movement of subsequent components. The bottom of the mounting rod 702 is movably fitted with a rotating ring 701, and multiple rotating rings 701 are arranged sequentially from top to bottom. The design of the rotating rings 701 allows relative rotation between the mounting rod 702 and the linkage shaft 703, thus providing the possibility of horizontal angle adjustment for the pipeline clamping and adjustment assembly 7. The arrangement of multiple rotating rings 701 can increase the stability and flexibility of the structure and adapt to different clamping requirements. A linkage shaft 703 is movably connected to one side of the rotating ring 701 via a bearing. The use of the bearing reduces the frictional resistance of the linkage shaft 703 during rotation, ensuring its smoothness and accuracy, and also extending the service life of the component. A first slider 704 is rotatably connected to one side of the linkage shaft 703 via a bearing, and the linkage shaft 703 passes through the first slider 704. This connection method allows the first slider 704 to rotate under the drive of the linkage shaft 703, and due to the bearing, the first slider 704 remains stable during rotation, without jamming or shaking. The linkage shaft 703 also passes through the side wall of the second slider 705 near the first slider 704, and the end face of the linkage shaft 703 is movably mounted on the inner wall of the other end of the second slider 705 via a bearing.

A second helical gear 706 is movably mounted on the bottom of the second slider 705. The second helical gear 706 plays a crucial role in the transmission system, transmitting power and changing the direction of motion. Its meshing accuracy with other gears directly affects the transmission efficiency and motion accuracy of the entire device. A worm gear 707 is fixedly connected to one side of the second helical gear 706. The meshing transmission between the worm gear 707 and the worm 708 has a self-locking characteristic, maintaining stability after the pipeline clamping position is adjusted, preventing changes in the clamping position due to external forces or vibrations. The top of the worm gear 707 meshes with the worm 708, which is movably mounted between two bearing seats 709 via a rotating shaft. The bearing seats 709 provide stable support and positioning for the rotation of the worm 708, ensuring the positional accuracy and smooth rotation of the worm 708 shaft during rotation. A knob 710 is fixedly connected to the rotating shaft on one side of the worm gear 708. The knob 710 serves as a manual operating component, allowing operators to intuitively control the movement of the pipe clamping and adjustment assembly 7. The position and angle of the pipe clamp 719 can be precisely adjusted by rotating the knob 710.

[0046] The pipeline clamping and adjustment assembly 7 also includes a pointer 711, a first pressure adapter plate 712, a fluid connecting pipe 713, and a second pressure adapter plate 714. The pointer 711 is fixedly installed on one side of the second slider 705. The pointer 711 is typically used in conjunction with a dial or marking to indicate the position or movement of the second slider 705. Operators can intuitively understand the adjustment status of the pipeline clamping and adjustment assembly 7 based on the pointer 711, facilitating precise operation and positioning. The first pressure adapter plate 712 is bolted to the top of the second slider 705, serving as a transition in fluid pressure transmission and component connection. It may be a metal plate with bolt holes, made of a material matching the second slider 705, providing a stable connection base for other components and participating in the pressure transmission path. This ensures stable transmission of fluid pressure between relevant components without leakage or pressure loss, which is crucial for measurement accuracy. A fluid connecting pipe 713 is fixedly installed on one side of the first pressure adapter plate 712 via annular fasteners. The fluid connecting pipe 713 is connected to the first pressure adapter plate 712 via annular fasteners and is also connected to the second pressure adapter plate 714, playing an important role in fluid conduction and the stability of the clamping structure. It may be a pipe fitting matching the inner diameter of the pipeline under test, and its material must have good sealing and corrosion resistance, such as stainless steel or engineering plastics, to ensure no leakage occurs during fluid transmission, maintain stable pressure within the pipeline, and ensure the reliability of measurement data. The second pressure adapter plate 714 is fixedly connected to one side of the fluid connecting pipe 713, structurally connecting the fluid connecting pipe 713 to the pipeline under test, ensuring stable fluid conduction between the pipeline and the device. Its design should be compatible with the port of the pipeline under test, possessing good sealing performance, and can employ rubber gaskets or special sealing structures to prevent fluid leakage, thereby ensuring the accuracy of pressure data during measurement.

[0047] The pipe clamping and adjustment assembly 7 also includes a linear groove 715, a servo motor 716, a bidirectional threaded shaft 717, an internal threaded slider 718, and a pipe clamp 719. The linear groove 715 is located on the top of the first slider 704, providing guidance and constraint for the linear movement of the internal threaded slider 718. Its shape is an elongated groove with high machining precision and a smooth inner wall to reduce frictional resistance during the movement of the internal threaded slider 718, ensuring smooth movement along a predetermined direction. This allows for precise control of the position of the pipe clamp 719, ensuring accurate clamping of pipes at different locations. A servo motor 716 is fixedly mounted on one side of the first slider 704, serving as the power source for adjusting the position of the pipe clamp 719. It accurately outputs torque and speed according to control signals, driving the bidirectional threaded shaft 717 to rotate, which in turn drives the internal threaded slider 718 to move within the linear groove 715, achieving precise control of the pipe clamp 719's position. It features high control precision and response speed, meeting the clamping requirements of pipelines with different diameters and ensuring the stability and reliability of the clamping process. A bidirectional threaded shaft 717 is fixedly mounted on the output end of the servo motor 716. The bidirectional threaded shaft 717 is connected to the output end of the servo motor 716. Its special bidirectional thread structure allows it to drive the internal threaded sliders 718 on both sides to perform linear motion in relative or opposite directions during rotation. Its thread precision is high, and the material has sufficient strength and wear resistance, such as alloy steel, to ensure that no thread wear or deformation occurs during long-term use, ensuring accurate clamping of the pipeline clamp 719. Internal threaded sliders 718 are symmetrically arranged on both sides of the bidirectional threaded shaft 717. The internal threaded sliders 718 cooperate with the bidirectional threaded shaft 717, achieving linear motion under the guidance of the linear groove 715. Its internal threads tightly mesh with the threads of the bidirectional threaded shaft 717. The material is generally metal, providing a certain weight and stability. During operation, it smoothly drives the pipe clamp 719, converting the rotational motion of the servo motor 716 into linear displacement of the pipe clamp 719, achieving precise clamping of the pipe. The top of the internally threaded slider 718 is fixedly connected to the pipe clamp 719, which is used to clamp the ports of the first and second pipes to be tested, 8 and 9. It needs to possess good clamping force and stability, be adaptable to pipes of different diameters, and not damage the pipes during clamping, ensuring the pipes' sealing and integrity. Its clamping surface is made of rubber or soft material, ensuring both secure clamping and no damage to the pipes under test. As a key component that comes into direct contact with the pipeline under test, the precise clamping performance of the pipe clamp 719 is crucial for obtaining accurate measurement data. By stably clamping the pipeline, it ensures stable fluid conduction between the pipeline and the device during the measurement process, avoiding the impact of leakage or poor connection on pressure measurement, thereby ensuring the accuracy of impedance calculation.

[0048] A curved slider is fixedly installed at the bottom of the first slider 704, and the curved slider is slidably connected inside the second annular slide rail 504. The bottom of the second slider 705 is slidably connected inside the first annular slide rail 503. The curved slider at the bottom of the first slider 704 is slidably connected inside the second annular slide rail 504, allowing the pipe clamping and adjustment assembly 7 to be adjusted at an angle around a certain arc. This is suitable for situations where the pipe port has a certain curvature change, such as the measurement of curved pipes. The curved slider at the bottom of the first slider 704 is made of wear-resistant metal or engineering plastic material, and its curvature matches the track of the second annular slide rail 504. Its surface is specially treated to reduce the coefficient of friction during sliding and ensure smooth sliding. The first slider 704 plays a key angle adjustment role in the device. Through cooperation with the second annular slide rail 504, the entire pipe clamping and adjustment assembly 7 can flexibly adapt to the pipe connection requirements of different angles. When facing complex pipe layouts, it can accurately adjust the clamping posture, ensuring the accuracy and reliability of the measurement and improving the adaptability of the device to various pipe structures.

[0049] The bearing housing 709 is fixedly installed on the inner wall of the second slider 705 near the pointer 711. The worm gear 707 and the second helical gear 706 are both fixedly installed on one side of the linkage shaft 703. The second helical gear 706 meshes with the top of the first helical gear 505. The bearing housing 709, fixedly installed on the inner wall of the second slider 705 near the pointer 711, serves to support and position the relevant transmission components. It possesses sufficient strength and stability to ensure that connected components, such as the worm gear 708, maintain accurate positional relationships during device operation. This ensures stable operation of the mechanical transmission structure, guarantees precise execution of clamping and measuring actions, and avoids measurement errors or clamping failures due to component displacement or shaking.

[0050] In the overall workflow of the device, the first test pipeline 8 and the second test pipeline 9 are first precisely clamped by the pipeline clamp 719. Under the control of the servo motor 716, the pipeline clamp 719 is adjusted according to the diameter and position requirements of the test pipeline to ensure the clamping is firm and airtight. At this time, the fluid flows in the pipeline, and the pressure is transmitted to the pressure testing device in the pressure detection chamber 3 through the second pressure adapter plate 714, the fluid connecting pipe 713, the first pressure adapter plate 712, and the pressure transmission pipe 4. The pressure testing device collects pressure data in real time and transmits the data to the data processing and communication unit 6 via wireless communication. The data processing and communication unit 6 calculates the impedance value of the fluid pipeline according to the received pressure data and known pipeline parameters such as pipe diameter and length, based on a preset impedance calculation algorithm. Throughout the process, the various components of the pipeline clamping and adjustment assembly 7 work in concert. The first slider 704 and the second slider 705 adjust their angle and position through the cooperation of the annular slide rail and the arc-shaped slider to adapt to the installation requirements of different pipelines. Gear transmission components such as the first helical gear 505, the second helical gear 706, the worm gear 707, and the worm 708 precisely control the movement of the pipeline clamp 719 under the drive of the knob 710 or other power source. The pointer 711 provides the operator with intuitive position indication, facilitating manual fine-tuning and monitoring. This design enables the device to not only adapt to various types of fluid pipeline impedance measurements but also ensure the accuracy and reliability of the data during the measurement process, providing strong technical support for the performance evaluation, fault diagnosis, and optimization design of fluid pipeline systems in industrial production.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
