Description

Technical Field

[0001] This invention relates to the field of monitoring technology, and in particular to a pipe support for thermal power units. Background Technology

[0002] In many industrial sectors such as power, chemical, and energy, pipeline systems are critical infrastructure for transporting fluid media (such as water, steam, and oil), and their long-term, stable, and safe operation is of paramount importance. Especially in thermal power units, pipelines used to transport high-temperature and high-pressure water or steam typically require support structures such as hangers and supports for fixation and load-bearing to resist the pipeline's own weight, thermal expansion, and various dynamic loads generated by the flow of the internal medium, such as vibration and water hammer effects.

[0003] Currently, common pipe hangers or support devices typically include basic structures such as horizontal bars, vertical bars, and connectors, which are fixed to the building structure by welding or bolting. Pipes are then installed on the horizontal bars using brackets or pipe clamps. However, this type of traditional hanger structure has significant limitations: During pipeline operation, especially during start-up, shutdown, or flow rate changes, the internal medium is prone to periodic water hammer effects or pressure fluctuations, inducing continuous pipeline vibration. Long-term vibration loads are transmitted to various connection points of the hangers, such as the connection between the bracket and the horizontal bar, and the fixing points between the vertical bar and the building structure, potentially leading to loose bolts, weld fatigue, or even structural deformation. The loosening or deformation of these connections is a gradual process, difficult to detect in routine inspections. Once the support position shifts, it not only alters the pipeline's stress state, accelerating localized stress concentration and fatigue damage, but may also cause leaks at pipeline joints, seriously affecting production safety and even triggering shutdown accidents.

[0004] In order to monitor the status of the hanger system, the existing technology usually uses manual periodic inspection, visual observation or simple tool measurement. This detection method is inefficient, has poor real-time performance, and is difficult to detect small, gradual displacements or loosening.

[0005] Some technologies attempt to install vibration or displacement sensors on the hangers, but the sensor layout is often complex and costly, and it is difficult to accurately distinguish between normal thermal displacement of the pipeline and abnormal displacement caused by structural loosening, or to comprehensively monitor multiple potential fault points (such as lateral displacement and vertical settlement) at the same time.

[0006] Therefore, there is an urgent need for a monitoring device that can be integrated into the pipe hanger itself, has a compact structure, is easy to install, and can monitor the status of key connection parts of the hanger (including lateral offset and vertical settlement) in real time and accurately, so that operation and maintenance personnel can promptly detect potential hazards and carry out preventive maintenance, thereby ensuring the long-term safe and stable operation of the pipeline system. Summary of the Invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to propose a pipe support for thermal power units. By including a pressure sensor in the detection component, the pressure sensor detects the air pressure in the detection space and changes in pressure within the space, sensitively reflecting the vertical settlement caused by foundation loosening of the vertical expansion joint. By including a distance sensor in the detection component, the distance sensor directly monitors the offset of the installation crossbar and determines the reliability of its connection with the installation crossbar. Integrating the detection content of the pressure sensor and the distance sensor provides multi-dimensional and accurate fault diagnosis basis. This design makes the monitoring results more scientific and comprehensive, significantly reduces the misjudgment rate, and provides precise maintenance guidance for operation and maintenance personnel. Furthermore, it realizes real-time, proactive monitoring and early warning of the support status of the hanger. It can sense and transmit minute changes in the displacement of the installation crossbar and the extension and contraction of the expansion joint in real time. Once the connection point of the hanger becomes loose due to vibration of the pipeline body, the monitoring system can immediately detect the anomaly through air pressure or distance signals, thereby issuing an early warning before the fault expands or water leaks inside the pipeline body. This greatly improves the safety and maintainability of the thermal power unit pipeline system and realizes the transformation from passive maintenance to proactive prevention.

[0008] According to an embodiment of the present invention, a pipeline support for a thermal power unit includes: a support body, comprising a mounting crossbar, two vertical support rods, and two tension rods. The vertical support rods extend vertically and are spaced apart along a first direction. A fixed seat is provided at the top of each vertical support rod, and the fixed seat is fixedly connected to a mounting base. The mounting crossbar extends along the first direction, and both ends of the mounting crossbar are fixedly connected to the bottoms of the two vertical support rods, respectively. The mounting crossbar is used to support the pipeline upwards. The two tension rods are spaced apart along the first direction, each tension rod corresponding to one of the vertical support rods. One end of each tension rod is provided with a mounting seat, which is fixedly connected to the mounting base. The other end of each tension rod is rotatably connected to the middle of the vertical support rod. The tension rod extends downwards in the direction from one end to the other. Two telescopic rods are also included. Two telescopic rods are spaced apart along a first direction, each corresponding to one of the two tension rods. Each telescopic rod includes a sleeve and a sliding rod. The sleeve is fitted onto the outer periphery of the sliding rod. One end of the sleeve along its length is sealed and rotatably connected to the tension rod. The other end of the sleeve along its length has an opening. The sliding rod is inserted into the sleeve through the opening. The end of the sliding rod away from the opening is connected to the mounting crossbar. A detection space is defined between the inner periphery of the sleeve and the sliding rod. A detection assembly is fixed to the telescopic rod. The detection assembly includes a pressure detection sensor and a distance detection sensor. The pressure detection sensor is used to detect the pressure of the detection space. The distance detection sensor is fixedly connected to the sleeve at a first detection point. A perpendicular line is drawn from the first detection point to the tension rod, and the foot of the perpendicular is the second detection point. The distance detection sensor is used to detect the distance between the first detection point and the second detection point.

[0009] According to embodiments of the present invention, the pipeline supports for thermal power units include a pressure sensor in the detection component. This pressure sensor detects the pressure in the detection space and changes in pressure within the space, sensitively reflecting vertical settlement caused by foundation loosening of the vertical expansion joint. The detection component also includes a distance sensor, which directly monitors the offset of the installation crossbar and determines the reliability of its connection with the crossbar. Integrating the detection data of the pressure sensor and the distance sensor provides multi-dimensional and precise fault diagnosis criteria. This design makes the monitoring results more scientific and comprehensive, significantly reducing the misjudgment rate and providing precise maintenance guidance for operation and maintenance personnel. Furthermore, it achieves real-time, proactive monitoring and early warning of the support status, capable of sensing and transmitting minute changes in the displacement of the installation crossbar and the extension / retraction of the expansion joint in real time. Once the connection point of the support becomes loose due to vibration of the pipeline body, the monitoring system can immediately detect the anomaly through pressure or distance signals, thereby issuing an early warning before the fault escalates or water leaks inside the pipeline body. This greatly improves the safety and maintainability of the thermal power unit pipeline system, realizing a shift from passive maintenance to proactive prevention.

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The following is for reference. Figures 1-8 A pipe support 100 for a thermal power unit according to an embodiment of the present invention is described.

[0024] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, the pipeline support 100 of the thermal power unit includes: a support body 1, two telescopic rods 2 and a detection component 4.

[0025] The support body 1 includes a mounting crossbar 11, two vertical support rods 12, and two tension rods 14. The vertical support rods 12 extend in the vertical direction and are spaced apart in a first direction. The top of the vertical support rod 12 is provided with a fixing seat 13, which is fixedly connected to the mounting base. The mounting crossbar 11 extends in the first direction, and both ends of the mounting crossbar 11 are fixedly connected to the bottom of the two vertical support rods 12 respectively. The mounting crossbar 11 is used to support the pipe 5 upward. The two tension rods 14 are spaced apart in the first direction, and each tension rod 14 corresponds to each vertical support rod 12. One end of the tension rod 14 is provided with a mounting seat 15, which is fixedly connected to the mounting base. The other end of the tension rod 14 is rotatably connected to the middle of the vertical support rod 12. The tension rod 14 extends downward in an inclined direction from one end to the other.

[0026] Two telescopic rods 2 are spaced apart along the first direction and correspond one-to-one with two tension rods 14. Each telescopic rod 2 includes a sleeve 22 and a sliding rod 21. The sleeve 22 is fitted on the outer periphery of the sliding rod 21. One end of the sleeve 22 in the length direction is sealed and rotatably connected to the tension rod 14. The other end of the sleeve 22 in the length direction is provided with an opening 221. The sliding rod 21 is inserted into the sleeve 22 through the opening 221. The end of the sliding rod 21 away from the opening 221 is connected to the mounting crossbar 11. The inner peripheral wall of the sleeve 22 and the sliding rod 21 define a detection space 222.

[0027] The detection component 4 is fixed to the telescopic rod 2. The detection component 4 includes a pressure detection sensor and a distance detection sensor. The pressure detection sensor is used to detect the pressure of the detection space 222. The distance detection sensor is fixedly connected to the sleeve 22 at the first detection point. A perpendicular line is drawn from the first detection point to the telescopic rod 14, and the position of the foot of the perpendicular is the second detection point. The distance detection sensor is used to detect the distance between the first detection point and the second detection point.

[0028] For example, the mounting base can be the indoor ceiling or other interior surfaces; the mounting base can also be a fixed device.

[0029] In the pipeline support 100 of the thermal power unit, the slight vibration or thermal expansion displacement of the pipeline 5 directly drives the installation crossbar 11 to move, which in turn drives the sliding rod 21 to move within the sleeve 22, thereby compressing or expanding the sealed detection space 222. Even if the sliding rod 21 only produces a small axial displacement, the change in volume within the sealed space will immediately cause significant pressure fluctuations.

[0030] The air pressure sensor detects the air pressure within the detection space 222. The detection space 222 can refer to the space defined between the inner circumferential wall of the sleeve 22 (near the sealing side) and the end of the sliding rod 21; or it can refer to... Figure 8 The opening 221 and the sliding rod 21 are sealed together, and the end of the sliding rod 21 is provided with a piston 212, which is sealed with the inner wall of the sleeve 22. The detection space 222 is the space defined between the inner peripheral wall of the sleeve 22 on the side close to the opening 221 along the length direction, the piston 212 and the outer peripheral wall of the sliding rod 21.

[0031] By including a pressure sensor in the detection component 4, which detects the pressure in the detection space 222, the difficult-to-capture mechanical displacement is converted into a signal that is easier to capture. Once the connection point of the hanger is loosened due to vibration of the pipeline 5 body, the monitoring system can immediately detect the abnormality through pressure or distance signals, thereby issuing an early warning before the fault expands or water leaks inside the pipeline 5 body. This greatly improves the safety and maintainability of the thermal power unit pipeline 5 system and realizes the transformation from passive maintenance to active prevention.

[0032] Furthermore, the detection component 4 includes a distance detection sensor, which directly measures the distance change between the first detection point and the second detection point, thereby detecting the displacement of the mounting crossbar 11 relative to the sleeve 22. This can cross-verify the accuracy of the air pressure data and directly determine whether the structure has undergone severe deformation.

[0033] By integrating the detection data from the barometric pressure sensor and the distance sensor, a multi-dimensional and precise fault diagnosis basis is provided. This design makes the monitoring results more scientific and comprehensive, significantly reduces the misjudgment rate, and provides maintenance personnel with accurate maintenance guidance.

[0034] By making the tension rod 14 extend downwards in the direction from one end to the other, an angle is set between the tension rod 14 and the body of the pipe 5, forming a triangle to more stably support the pipe 5 upwards. By connecting one end of the telescopic rod 2 to the tension rod 14 and the other end of the telescopic rod 2 to the mounting crossbar 11, when the pipe 5 is installed on the mounting crossbar 11, the mounting crossbar 11 lifts the pipe 5 upward. Since the telescopic rod 2 stretches the mounting crossbar 11, the telescopic rod 2 is stretched, and the air pressure in the detection space 222 tends to recover its own air pressure, driving the piston 212 to support the sliding rod 21 obliquely upward. This allows the structure of the telescopic rod 2 to work with the tension rod 14 to stretch the mounting crossbar 11, making the pipe 5 more stably installed on the thermal power unit pipe support 100. When the pipe 5 is subjected to impact force causing the mounting crossbar 11 to shift, the telescopic rod 2 plays an auxiliary stretching role for the mounting crossbar 11. Even if it is inconvenient for the staff to inspect the pipe 5 in time, the telescopic rod 2 can also prevent the mounting crossbar 11 from falling off and avoid danger.

[0035] When the mounting crossbar 11 is impacted by the pipe 5 and undergoes horizontal displacement, it moves towards the support rod. The crossbar 11 pushes and pulls the bottoms of the two vertical support rods 12, causing them to tilt in the same direction. This tilting motion, through the connection point in the middle of the vertical support rods 12, pulls the tension rod 14, causing it to swing horizontally around the top mounting base 15. This, in turn, drives the universally connected telescopic rod 2 to be compressed along its own axis. At this time, the pressure sensor detects the pressure increase caused by the decrease in the volume of the detection space 222, while the distance sensor simultaneously measures the increase in the distance between the first and second detection points. These two measurements corroborate each other, indicating that the impact force displaces the mounting crossbar 11, potentially placing the thermal power unit pipe support 100 in a dangerous state.

[0036] For example, the pipeline support 100 of the thermal power unit includes two detection components 4, which are arranged at intervals along a first direction and are respectively integrated on the sleeves 22 of the two telescopic rods 2. The air pressure detection sensor in each detection component 4 is connected to the internal detection space 222 and is used to detect the air pressure in the detection space 222 of the corresponding telescopic rod 2. The distance detection sensor in each detection component 4 is fixed to the outer wall of the corresponding sleeve 22. The distance detection sensor and the sleeve 22 where the distance detection sensor is located are fixed at the first detection point. The connection point between the sleeve 22 where the distance detection sensor is located and the mounting crossbar 11 is the corresponding second detection point. The two distance detection sensors respectively detect the distance between their corresponding first detection point and second detection point, thereby forming a completely symmetrical monitoring layout on both sides of the pipeline 5.

[0037] Ideally, the stress state on both sides of pipe 5 should be symmetrical. By comparing the differences in readings from the two air pressure sensors and the two distance sensors, the nature of the fault can be accurately determined: synchronous changes in data on both sides usually indicate overall thermal expansion of the piping system or foundation settlement, while sudden changes in data on one side can accurately locate asymmetrical faults such as local jamming, loosening or tilting of hangers on one side.

[0038] According to an embodiment of the present invention, the pipeline support 100 of the thermal power unit includes a pressure detection sensor in the detection component 4. The pressure sensor detects the pressure in the detection space 222, and the pressure change within the detection space 222 sensitively reflects the axial expansion and contraction of the telescopic rod 2, making the detection more accurate. Furthermore, by including a distance detection sensor in the detection component 4, the distance detection sensor directly monitors the offset of the mounting crossbar 11 and determines the reliability of its connection with the mounting crossbar 11. Integrating the detection data of the pressure detection sensor and the distance detection sensor provides a multi-dimensional and accurate basis for fault diagnosis. This design enhances the monitoring... The test results are more scientific and comprehensive, significantly reducing the misjudgment rate and providing precise maintenance guidance for operation and maintenance personnel. Furthermore, it enables real-time and proactive monitoring and early warning of the support status of the hangers. It can sense and transmit minute changes in the displacement of the installation crossbar 11 and the extension and retraction of the telescopic rod 2 in real time. Once the connection point of the hanger is loosened due to vibration of the pipeline 5 body, the monitoring system can immediately detect the abnormality through air pressure or distance signals, thereby issuing an early warning before the fault expands or water leaks inside the pipeline 5 body. This greatly improves the safety and maintainability of the thermal power unit pipeline 5 system and realizes the transformation from passive maintenance to proactive prevention.

[0039] Reference Figure 8According to some embodiments of the present invention, the sliding rod 21 includes a rod body 211 and a piston 212. The piston 212 is fixed to one end of the rod body 211 that extends into the sleeve 22, and the outer peripheral wall of the piston 212 abuts against and seals the inner peripheral wall of the sleeve 22. By making the telescopic rod 2 include the piston 212, and the piston 212 precisely contacting and fitting with the inner wall of the sleeve 22, the airtightness of the detection space 222 is excellent, and the sealing performance is better, avoiding air leakage that would cause the air pressure change in the detection space 222 to be insignificant and difficult to detect during the telescopic movement of the telescopic rod 2. Furthermore, by using the piston 212 to replace the direct friction of the sliding rod 21 body, the guiding accuracy and wear resistance of the telescopic rod 2 are significantly improved while ensuring sealing.

[0040] Reference Figure 4 According to some embodiments of the present invention, the lower end of the tension rod 14 is provided with a second universal joint 33, and the vertical support rod 12 is provided with a second universal support, and the second universal joint 33 and the second universal support are rotatably connected.

[0041] By making the second universal joint 33 rotatably connected to the second universal support, the bending constraints at both ends of the tension rod 14 are mechanically released, making the tension rod 14 an ideal two-force rod. The tension rod 14 is only responsible for transmitting the axial tensile force generated by the load of the pipe 5 to the installation base, avoiding the risk of the connection point between the tension rod 14 and the vertical support rod 12 breaking due to the additional bending moment introduced on the tension rod 14 by the displacement of the pipe 5 or the installation deviation.

[0042] Reference Figure 3 According to some embodiments of the present invention, the lower end of the telescopic rod 2 is provided with a first universal joint, and the mounting crossbar 11 is provided with a first universal support, and the first universal joint and the first universal support are rotatably connected.

[0043] By rotatably connecting the first universal joint to the first universal support, the bending moment constraint at the connection between the telescopic rod 2 and the mounting crossbar 11 can be released, allowing the telescopic rod 2 to bear only the tension or pressure along the rod axis. This makes the axial displacement of the telescopic rod 2 more accurately reflect the real load change of the pipeline 5, thereby making the judgment of the pipeline 5 status more accurate based on the data measured by the air pressure detection sensor and the distance detection sensor.

[0044] Reference Figure 5 and Figure 6 According to some embodiments of the present invention, the tension rod 14 is provided with a connecting seat 36 in the middle, and the top of the sleeve 22 is provided with a third universal joint, which is rotatably connected to the connecting seat 36.

[0045] By rotatably connecting the third universal joint to the connecting seat 36, a hinge constraint is formed at the end where the telescopic rod 2 is connected to the tension rod 14. This allows the telescopic rod 2 to bear only the tension or pressure along its own axis, preventing lateral bending moments from being introduced into the telescopic rod 2 due to changes in the posture of the tension rod 14 or installation deviations. This protects the sealing fit between the internal piston 212 and the sleeve 22 from wear damage and makes the axial displacement of the telescopic rod 2 more accurately reflect the real load changes of the pipeline 5. As a result, the data measured by the air pressure detection sensor and the distance detection sensor are used to determine the status of the pipeline 5 more accurately.

[0046] According to some embodiments of the present invention, the distance detection sensor and the air pressure detection sensor are arranged side by side and attached together along the length direction of the telescopic rod 2.

[0047] For example, the detection component 4 also includes a base, which is fixed to the sleeve 22. Both the distance detection sensor and the air pressure detection sensor are fixed to the base. Integrating the two sensors into a single monitoring unit with a shared base not only saves installation space and reduces the number of exposed cables and connectors, but also structurally eliminates the relative positional deviation caused by separate installation. During installation, personnel only need to fix this one base to simultaneously obtain the two key parameters of air pressure and distance, which greatly simplifies the complexity of installation and improves the consistency of long-term monitoring.

[0048] Reference Figure 5 According to some embodiments of the present invention, the distance detection sensor is located at the lower end of the side wall of the sleeve 22. By placing the distance detection sensor at the lower end of the side wall of the sleeve 22, the distance between the connection point between the sleeve 22 and the tension rod 14 and the distance detection sensor is relatively large. When the bracket 112 shifts laterally on the mounting crossbar 11, it drives the sliding rod 21 to rotate, thereby causing the sleeve to swing around the connection point between the sleeve and the tension rod 14 as a fulcrum, causing the angle between the telescopic rod 2 and the tension rod 14 to change. By setting the measuring point far away from the connection point between the telescopic rod 2 and the tension rod 14, the small change in the angle between the telescopic rod 2 and the tension rod 14 can be significantly amplified into a large change in the distance between the first detection point and the second detection point, thereby enabling the distance detection sensor to obtain the highest measurement sensitivity and resolution, ensuring that early, minute displacements of the mounting crossbar 11 can be accurately captured.

[0049] Reference Figure 7According to some embodiments of the present invention, the mounting crossbar 11 includes a crossbar body 111 and two brackets 112. The two brackets 112 are fixed above the crossbar body 111 and are spaced apart along the length of the crossbar body 111. The brackets 112 are used to support the pipe 5 upwards. By providing two brackets 112 on the crossbar body 111, the contact area between the brackets 112 and the pipe 5 can be increased, making the support of the brackets 112 for the pipe 5 more secure. Furthermore, the brackets 112 can be set into an arc shape to match the pipe 5, providing more angle and more directional support force to the pipe 5, and more effectively preventing the pipe 5 from falling off.

[0050] Reference Figure 2 and Figure 3 According to some embodiments of the present invention, the lower end of the telescopic rod 2 is rotatably connected to the bracket 112, and the connection point between the telescopic rod 2 and the bracket 112 is located at the ends of the two brackets 112 that are away from each other.

[0051] By rotatably connecting the lower end of the telescopic rod 2 to the bracket 112, the bracket 112, as the direct support and transmission component for the load of the pipe 5, can more accurately and in real time transmit the vertical vibration, horizontal lateral thrust, and local micro-deformation of the pipe 5 directly to the telescopic rod 2. This bypasses the deformation and damping attenuation that may occur in the force transmission path of the intermediate structure, the crossbar body 111, making the telescopic rod 2's telescopic movement more sensitive and accurate. Consequently, the data measured by the air pressure detection sensor and the distance detection sensor are closer to the actual state of the bracket 112, effectively avoiding measurement lag or numerical distortion caused by the rigidity of the crossbar body 111 itself.

[0052] Reference Figure 5 According to some embodiments of the present invention, the mounting base 15 includes a first mounting plate, a second mounting plate and a connecting hinge 153. The first mounting plate is placed horizontally and fixedly connected to the mounting base. The top of the second mounting plate is rotatably connected to the first mounting plate through the connecting hinge 153. The top of the tension rod 14 is fixedly connected to the second mounting plate.

[0053] By making the fixed base 13 include a first mounting plate and a second mounting plate that are rotatably connected by a hinge, when the mounting crossbar 11 sways horizontally due to the impact or vibration of the pipe 5, the displacement generated by the swaying will be transmitted to the tension rod 14. However, the rotational freedom provided by the connecting hinge 153 allows the second mounting plate to swing adaptively with the swaying direction, avoiding the problem of damage to the mounting point of the fixed base 13 due to stress concentration.

[0054] Reference Figure 6 and Figure 7According to some embodiments of the present invention, the vertical support rod 12 includes a first mounting rod 121 and a second mounting rod 122. The first mounting rod 121 is disposed on the top of the second mounting rod 122 and at least a portion of the first mounting rod 121 is sleeved on the outer periphery of at least a portion of the second mounting rod 122. The top of the first mounting rod 121 is provided with a fixing seat 13, and the bottom of the second mounting rod 122 is fixedly connected to the mounting crossbar 11. The second mounting rod 122 can move in the vertical direction relative to the first mounting rod 121.

[0055] During normal operation of the thermal power unit, pipeline 5 will vibrate due to medium flow, water hammer effect, etc. This vibration will be transmitted to the vertical support rod 12 through the mounting crossbar 11. If the vertical support rod 12 is a rigid structure, this instantaneous huge displacement will be completely constrained, resulting in a huge impact force acting directly on the fixing point and support structure of pipeline 5, which may cause damage to the pipeline 5 support or installation node. By making the vertical support rod 12 include the first mounting rod 121 and the second mounting rod 122, the vertical support rod 12 can undergo high-frequency small-amplitude expansion and contraction under impact force, absorbing the impact energy through movement. This not only protects the vertical support rod 12 itself from being crushed by instantaneous stress, but also weakens the large-amplitude destructive impact of pipeline 5.

[0056] Furthermore, since the vertical support rod 12 has a small range of expansion and contraction during the water hammer effect, and the normal vibration displacement is much smaller than the displacement under fault conditions, the distance detection sensor and the air pressure detection sensor can distinguish between the normal state and the fault state of the thermal power unit pipeline support 100.
