[0032] The utility model discloses a pipeline strain monitoring device adopts chain 1 as fixed structure, and its both ends can detachably connect and form annular clamp, can conveniently surround the outer periphery of pipeline main body 100. The design of adjustable length of chain 1 makes the device can be applicable to the pipeline main body 100 of different pipe diameters, improves the versatility and application scope of the device.

In summary, the device has relatively simple structure, convenient installation, does not need complex operation and professional skill, saves installation time and labor cost, can be applied to the pipeline main body 100 of different pipe diameters, and has high flexibility and adaptability.
[0033] The specific structure of the pipeline strain monitoring device will be described below.
[0034] Chain 1 includes a plurality of connection sections 12 connected in sequence, and adjacent two connection sections 12 are rotationally connected, so that each connection section 12 can rotate by a certain angle relative to the adjacent connection section 12, so that chain 1 can better fit the shape of pipeline main body 100, especially when pipeline main body 100 has a bending or irregular surface, chain 1 can be flexibly adjusted according to the shape of pipeline main body 100, so as to be more closely and stably arranged around the outer periphery of pipeline main body 100, ensuring the accuracy and reliability of monitoring. In addition, when pipeline main body 100 has a slight displacement or deformation during operation, the rotationally connected connection sections 12 can adjust the position accordingly, reduce the interaction force between chain 1 and pipeline main body 100, reduce the additional influence on pipeline main body 100, and also help to protect chain 1 and strain gauge 22, prolong the service life of the device.
[0035] Specifically, one end of each connection section 12 is provided with a protruding connecting shaft, and the other end is provided with a matching connecting hole. The rotationally connected connection sections 12 are realized by inserting the connecting shaft of one connection section 12 into the connecting hole of the other connection section 12. The connection between the connecting shaft and the connecting hole is tight, which can ensure flexible rotation and will not produce too large gap.
[0036] In other embodiments, the rotation connection between the two adjacent connecting segments 12 can also be realized by a hinge structure, a universal joint, a pin shaft and a bushing structure, etc., which are not limited herein.
[0037] The length of the chain 1 is adjustable to adapt to the pipe body 100 with different diameters. Specifically, one end of the chain 1 is movably connected with the extension segment 11, the extension segment 11 can move along the extension direction of the chain 1 to adjust the length of the chain 1, and is fixed by the locking member 15. The other end of the chain 1 is detachably connected with the extension segment 11.
[0038] Specifically, the locking member 15 is a fixing nail, the extension segment 11 is slidably connected with one end of the chain 1, and a plurality of positioning holes are arranged on the extension segment 11 along the extension direction of the extension segment 11. When the extension segment 11 is moved to a suitable position, the fixing nail is inserted through the corresponding hole on the chain 1 and the positioning hole on the extension segment 11, so as to fix the position of the extension segment 11 and realize the adjustment of the length of the chain 1.
[0039] In actual operation, when the pipe diameter of the pipe body 100 is large and the length of the chain 1 is insufficient, the extension segment 11 is pulled out to increase the total length of the chain 1 until the chain 1 can be arranged around the outer periphery of the pipe body 100. Then, a suitable positioning hole is selected and a fixing nail is inserted to complete the fixing. When the pipe diameter of the pipe body 100 is small, the same principle applies, which is not described herein.
[0040] In other embodiments, to realize the length adjustment of the chain 1, a telescopic sleeve rod structure can be used, the chain 1 is composed of an inner sleeve rod and an outer sleeve rod, and the relative positions of the inner rod and the outer rod are fixed by fixing pins arranged at different positions, so as to realize the length adjustment of the chain 1. In addition, a threaded segment can be arranged at one end of the chain 1, and the extension segment 11 has a matching thread inside. The position of the extension segment 11 on the threaded segment is changed by rotating the extension segment 11, so as to adjust the length of the chain 1, etc. The specific implementation form is not limited herein, as long as the length adjustment of the chain 1 can be realized.
[0041] In order to realize the detachable connection of the two ends of the chain 1, one of the other end of the chain 1 and the extension segment 11 is provided with a buckle 14, and the other is provided with a clamping groove, and the buckle 14 and the clamping groove can be clamped with each other. Specifically, in the present embodiment, the buckle 14 is arranged on the extension segment 11, and the clamping groove is arranged on the other end of the chain 1. In other embodiments, the buckle 14 can be arranged on the other end of the chain 1, and the clamping groove can be arranged on the extension segment 11.
[0042] In addition, the detachable connection of the two ends of the chain 1 can also be achieved by installing magnets with opposite magnetic properties at the two ends of the chain 1, and then achieving detachable connection through magnetic attraction. Alternatively, a hook can be provided at one end of the chain 1, and a ring can be provided at the other end, and the hook can be hung into the ring to achieve connection, and the like, which will not be described here in detail, as long as the detachable connection of the two ends of the chain 1 can be achieved.
[0043] In order to improve the stability of the chain 1, in the present embodiment, two chains 1 are provided, which are arranged in parallel at intervals, and each end of the strain gauge 22 is connected to one chain 1, so as to provide more stable and balanced support for the strain gauge 22. Compared with a single chain 1, the two chains 1 can better share the external force that the pipeline body 100 may exert on the strain gauge 22, reduce the measurement error caused by uneven force on the strain gauge 22, and thus improve the accuracy and reliability of the strain measurement. Moreover, the two parallel and interval arranged chains 1 can better adapt to the shape change of the pipeline body 100. When the pipeline body 100 is locally deformed or bent, the two chains 1 can constrain and support from different positions and angles, further ensuring that the strain gauge 22 can accurately measure the strain state of the pipeline body 100.
[0044] Specifically, a plurality of support rods 13 are arranged between the two chains 1, and each end of the support rod 13 is connected to one chain 1. The plurality of support rods 13 are arranged at intervals along the extension direction of the chain 1, thereby forming an effective support frame between the two chains 1. When the chain 1 is affected by external force or deformation of the pipeline body 100, the chain 1 can maintain a relatively stable position and shape, thereby ensuring that the strain gauge 22 can accurately measure the strain of the pipeline body 100, and improving the accuracy and reliability of the measurement.
[0045] The strain gauge 22 is arranged on the chain 1 and is used to measure the strain state of the pipeline body 100. Specifically, the included angle between the strain gauge 22 and the axis of the pipeline body 100 is the measurement angle, and at least part of the strain gauges 22 have different measurement angles. By arranging strain gauges 22 with different measurement angles, more comprehensive and multi-angle strain information of the pipeline body 100 in different directions can be obtained. Since the force and strain of the pipeline body 100 during operation can be multi-directional, strain gauges 22 with different angles can capture more abundant strain data, thereby more accurately evaluating the overall strain state of the pipeline body 100. It can also effectively detect and distinguish complex stress conditions of the pipeline body 100. For example, it can distinguish whether it is axial tension, circumferential compression or other complex combined stress, and provide more accurate basis for analyzing the stress condition of the pipeline body 100 and possible potential problems.
[0046] Specifically, along the extension direction of the chain 1, every three strain gauges 22 form a group, and the measurement angles of the three strain gauges 22 in each group are 0 degrees, 45 degrees and 135 degrees in turn.
[0047] In other embodiments, the measurement angle of each strain gauge 22 along the extension direction of the chain 1 can also be different, and the difference between the measurement angles of every adjacent two strain gauges 22 is 5 degrees. For example, the measurement angle of the strain gauge 22 close to the end is 0 degrees, the measurement angle of the next adjacent strain gauge 22 is 5 degrees, the measurement angle of the next strain gauge 22 is 10 degrees, and so on.
[0048] After the strain gauges 22 measure the strain state of the pipeline body 100, feedback signals need to be generated and received by the controller 21 for subsequent processing. The controller 21 is signal-connected with the strain gauges 22 through the signal lines 24, and the signal lines 24 can realize stable and reliable signal transmission between the controller 21 and the strain gauges 22. It ensures that the strain state information of the pipeline body 100 measured by the strain gauges 22 can be accurately and timely transmitted to the controller 21, avoiding signal loss or distortion, thereby improving the accuracy of monitoring. Multiple strain gauges 22 share one controller 21, which on the one hand reduces the investment in hardware devices, making the entire monitoring device more cost-effective and conducive to large-scale application and promotion. On the other hand, sharing one controller 21 facilitates centralized management and control. Through one unified controller 21, the working state, parameter setting and data acquisition of all strain gauges 22 can be centrally regulated and controlled, improving the management efficiency and operation convenience of the system.
[0049] Since the controller 21 and the strain gauges 22 are connected through the signal lines 24, it is necessary to ensure that the distance between the controller 21 and the strain gauges 22 is not too far to ensure efficient transmission of the signal lines 24 and space utilization. Therefore, the controller 21 is provided with a magnet member 23, and the controller 21 is magnetically connected with the pipeline body 100 through the magnet member 23. Through the magnetic connection, the controller 21 can be flexibly installed at different positions of the pipeline body 100, which is convenient for selecting the optimal installation point according to the actual situation to maximize the layout of the signal lines 24, improve the space utilization, avoid the disorder or damage caused by the excessive length of the signal lines 24, and also reduce the signal attenuation caused by the excessive length of the signal lines 24.
[0050] Further, the controller 21 is provided with a signal transmitter 25, which is used to send the strain value generated by the controller 21 to an external device, so that the operator can obtain the strain information of the pipeline body 100 in real time and intuitively, so as to be able to quickly take countermeasures, such as adjusting the pipe cutting process parameters, to avoid damage caused by excessive strain of the pipeline body 100. The external device can be a mobile phone, a computer or other control terminal, which will not be described here.
[0051] The above embodiments only illustrate the basic principles and characteristics of the present application, and the present application is not limited to the above embodiments. Without departing from the spirit and scope of the present application, various changes and modifications can be made to the present application, and these changes and modifications all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
