Technical Field
[0001] The utility model relates to the technical field of concrete component stress monitoring, in particular to a long-distance water pipeline deformation monitoring device based on optical fiber monitoring. Background Art
[0002] In the early days of monitoring the stress of concrete components, a group of resistance strain gauges or FBG sensors were usually installed along the axial surface of the concrete components. However, the resistance strain gauges or FBG sensors monitor discrete measurements and it is difficult to directly obtain the strain changes along the entire length of the concrete component. Distributed optical fiber sensing technology has been widely used in the field of concrete component stress monitoring due to its characteristics of distributed, long distance, real-time and high precision. Many scholars at home and abroad have achieved beneficial research results.
[0003] In the existing monitoring devices, most of them lack a fixing clamping mechanism for the outside of the water pipe, which causes the relative position of the optical fiber to change, which may affect the stability of the sensor. A stable positional relationship is crucial for accurately monitoring pipeline deformation, otherwise it may cause errors and fail to accurately monitor the deformed areas. In addition, if the monitoring device lacks a snap-on connection mechanism, it may lead to the inability to connect multiple monitoring devices when monitoring is required, and the empty area in the middle cannot be monitored, resulting in the omission of part of the pipeline, causing potential monitoring blind spots and reducing the reliability of the monitoring system. Utility Model Content

The utility model provides and aims to improve the prior art, which causes the relative position of the optical fiber to change, which may affect the stability of the sensor. A stable position relationship is crucial for accurately monitoring pipeline deformation, otherwise it may cause errors and fail to accurately monitor the deformed area. In addition, it may lead to the inability to connect multiple monitoring devices when monitoring is required, and it is impossible to monitor the empty area in the middle, resulting in the omission of part of the pipeline, causing a potential monitoring blind spot, and reducing the reliability of the monitoring system.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a long-distance water pipeline deformation monitoring device based on optical fiber monitoring, comprising a shell, wherein the left and right ends of the interior of the shell are fixedly connected with fixing rings, the interiors of the two fixing rings are provided with guide rail grooves, multiple groups of connecting rods are slidingly connected inside the guide rail grooves, the left and right sides of multiple groups of connecting rods are fixedly connected with connecting rings, the inner side walls of multiple groups of connecting rings are arranged on the left and right outer sides of the guide rail grooves, the other ends of multiple groups of guide rail grooves are fixedly connected with support columns, the outer sides of the three support columns are fixedly connected with arc plates, the bottoms of the three support columns are fixedly connected with connecting plates, the bottom side walls of the three connecting plates are fixedly connected with connecting columns, and the bottoms of the multiple groups of connecting columns are fixedly connected with support plates.
[0006] Furthermore, a second connecting rod is fixedly connected to the top left slot of the shell, the middle outer side of the second connecting rod is rotatably connected to a limiting plate, a buckle is fixedly connected to the top slot of the shell, and the limiting plate and the buckle are arranged correspondingly.
[0007] Furthermore, a fixing plate is fixedly connected to the outer side of one of the connecting rods, a handle is fixedly connected to the top of the fixing plate, and the fixing plate is slidably connected to the top slot of the shell.
[0008] Furthermore, a first clamping ring is fixedly connected to the left end of the shell, and a groove is provided inside the first clamping ring.

[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The utility model can solve the problem of changes in the relative position of the optical fiber, which may affect the stability of the sensor, by providing the guide groove, the first connecting rod, the connecting column, the support plate, the handle and the arc plate. A stable position relationship is crucial for accurately monitoring the deformation of the pipeline, otherwise it may cause errors and fail to accurately monitor the deformed area. The pipeline is monitored by fixing the optical fiber in the hole groove inside the support plate. When clamping the water pipeline, the first connecting rod connected to the bottom is slid on the guide groove inside the fixing ring by sliding the handle to drive the fixed support column at the rear to rise and fall. When lifting and falling, the support plate is supported and connected by the fixed connecting column at the bottom of the connecting plate to drive the support plate to be placed on the outside of the water pipeline to clamp the water pipeline to monitor whether the water pipeline is deformed on the outside, thereby effectively improving the relatively stable position of the optical fiber during the monitoring process, better monitoring the deformed area on the water pipeline, and improving the accuracy and reliability of the monitoring device.
[0013] 2.

[0027] like Figure 1 - Fig. 9As shown, a long-distance water pipeline deformation monitoring device based on optical fiber monitoring includes a shell 1, and the left and right ends of the shell 1 are fixedly connected with fixing rings 2, and the insides of the two fixing rings 2 are opened with guide rail grooves 3, and multiple groups of first connecting rods 4 are slidingly connected inside the guide rail grooves 3. The left and right sides of multiple groups of first connecting rods 4 are fixedly connected with connecting rings 5, and the inner side walls of multiple groups of connecting rings 5 are arranged on the left and right outer sides of the guide rail grooves 3. The other ends of the multiple groups of guide rail grooves 3 are fixedly connected with support columns 6, and the outer sides of the three support columns 6 are fixedly connected with arc plates 11. The bottoms of the three support columns 6 are fixedly connected with connecting plates 7, and the bottom side walls of the three connecting plates 7 are fixedly connected with connecting columns 8. The bottoms of the multiple groups of connecting columns 8 are fixedly connected with support plates 9.
[0028] The internal device is protected by the outer shell 1, and the first connecting rod 4 is controlled by the handle 10 on the outside. When the staff slides the handle 10 by hand, the first connecting rod 4 will be driven to slide in the guide groove 3 inside the fixing ring 2 to drive the connected device to rise and fall and clamp the water pipe. When sliding, the arc plate 11 on the supporting column 6 connected to the rear of the first connecting rod 4 will be used to connect the other two supporting columns 6. When one of the first connecting rods 4 slides, the other two will be driven to slide simultaneously to clamp and fix the water pipe. When lifting and lowering, the connecting plate 7 on the bottom wall of the support column 6 will be connected to the support plate 9 to drive the support plate 9 to rise and fall and fix the water pipe.
[0029] like Figure 1 - Figure 5 As shown, a second connecting rod 20 is fixedly connected to the top left slot of the shell 1, and a limiting plate 21 is rotatably connected to the middle outer side of the second connecting rod 20. A buckle 22 is fixedly connected to the top slot of the shell 1, and the limiting plate 21 is arranged corresponding to the buckle 22. A fixing plate 19 is fixedly connected to the outer side of a first connecting rod 4, and a handle 10 is fixedly connected to the top of the fixing plate 19. The fixing plate 19 is slidably connected in the top slot of the shell 1.
[0030] When the device is lowered and clamped, the limit plate 21 on the top of the shell 1 will rotate on the outside of the second connecting rod 20, and the limit plate 21 will be fixed on the outside of the buckle 22 to prevent the handle 10 from sliding and restoring.
[0031] like Figure 1 - Fig. 9As shown, a first snap ring 12 is fixedly connected to the left end of the outer shell 1, a groove 13 is provided inside the first snap ring 12, a second snap ring 14 is fixedly connected to the right end of the outer shell 1, a connecting buckle 15 is fixedly connected to the right side of the second snap ring 14, a connecting plate 16 is fixedly connected to the top and left and right sides of the first snap ring 12 and the second snap ring 14, the groove 13 and the connecting buckle 15 are arranged correspondingly, bolts 17 are arranged inside the two connecting plates 16, and a nut 18 is threadedly connected to the bottom end of the bolt 17.
[0032] The two devices are connected by inserting the connecting buckle 15 on the right side of the second retaining ring 14 into the groove 13 inside the first retaining ring 12 on the left side of the other device. After the connection, the coupling plates 16 on the outer sides of the first retaining ring 12 and the second retaining ring 14 will be engaged. The bolts 17 are inserted into the interior of the engaging plates 16 after engagement to strengthen the fixation and prevent loosening and disconnection. The nuts 18 at the bottom of the bolts 17 are used for further fixation.
[0033] It should be noted that the utility model is a long-distance water pipeline deformation monitoring device based on optical fiber monitoring. First, three optical fibers are fixed in the holes on three support plates 9 respectively. The arrangement of the holes can make the optical fibers fully contact with the water pipeline without damaging the optical fibers. The three optical fibers are connected to the BOTDA demodulator through jumpers to realize the collection of strain data. The strains monitored by the three sensing optical fibers arranged in the water pipeline are compared and analyzed to determine the main strain, main strain direction, bending deflection, horizontal stress, vertical stress, shear stress, main stress and multi-component stress in the main stress direction of the water pipeline, so as to realize the deformation monitoring of the water pipeline.
[0034] When clamping the water pipe, the first connecting rod 4 connected at the bottom is slid on the guide groove 3 inside the fixing ring 2 by sliding the handle 10, so as to drive the fixed support column 6 at the rear to rise and fall. When sliding, the arc plate 11 on the outer side of the support column 6 is connected with the other two groups of support columns 6, so as to drive the other two groups of fixed support plates 9 to slide and rise and fall at the same time;
[0035] When lifting, the support plate 9 will be supported and connected by the fixed connecting column 8 at the bottom of the connecting plate 7, so as to drive the support plate 9 to be placed on the outside of the water pipe, to clamp the water pipe, and to monitor whether the water pipe is deformed on the outside. After sliding down, the limit plate 21 on the top slot of the outer shell 1 will rotate on the outside of the second connecting rod 20 and be fixed on the outside of the buckle 22 for limiting.
[0036] When the clamping device is not long enough and multiple devices are needed for monitoring, the connection is made by inserting the connecting buckle 15 on the second clamping ring 14 into the groove 13 inside the first clamping ring 12 on the housing 1 of another device. After the connection, the second clamping ring 14 and the connecting plate 16 on the outside of the first clamping ring 12 will fit together, and the bolt 17 will be inserted into the interior of the connecting plate 16 and then fixed by the nut 18.
