Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gas pipeline settlement monitoring, specifically to a device for a visual reading vector displacement sensor. Background Technology
[0002] Gas pipelines typically run underground to the building and then emerge above ground to enter the household. The pipelines are secured from underground to the surface using fixing devices. However, they are susceptible to damage if the new backfill soil is not compacted sufficiently, causing the buried pipeline to sink along with it, which could break the pipeline and lead to a major gas leak.
[0003] Currently, the monitoring equipment installed on gas risers or corrugated compensators are all vector displacement sensors. One end is fixed to the wall, and the other end is fixed to the pipe (or, if used with a compensator, it's fixed to the flanges at both ends of the compensator). When the pipe detects displacement, it pulls the vector displacement sensor to detect the change. The vector displacement sensor internally consists of a moving brush and a resistive element. Changes in the moving brush cause changes in resistance, which are then converted into a digital signal and uploaded to a platform for display via an IoT device. However, this method cannot be used for remote or near-end wireless monitoring when there is no power or when the IoT device has no signal, nor can the displacement data be visually inspected on-site. Furthermore, if a sudden and excessive settlement occurs, causing the pipeline to malfunction, it cannot resolve issues such as gas leaks. Utility Model Content
[0004] This application proposes a visual reading vector displacement sensor device that is simple, low-cost, and easy to read. In the event of a sudden excessive settlement, it can also switch the circuit to prevent gas leakage and improve the safety of gas use.
[0005] Therefore, this application provides a device for a visual reading vector displacement sensor, including a vector displacement sensor, wherein the vector displacement sensor is provided with a visual displacement reading mechanism;
[0006] The visual displacement reading mechanism includes a scale laser-engraved on the front of the vector displacement sensor, a scale needle fixed to the telescopic rod of the vector displacement sensor by fixing screws, and a reset spring disposed between the vector displacement sensor and the telescopic rod.
[0007] It also includes a switching mechanism set on the scale needle.
[0008] By adopting the above technical solution: a scale needle is added to the original vector displacement sensor, and millimeter scales are laser-engraved on the surface of the vector displacement sensor, with positive and negative values at the top and bottom and 0 value in the middle. After installation, the scale needle needs to be fixed at the 0 value position. When the monitored object changes displacement, it drives the scale needle to move. The mark that the arrow of the scale needle points to is the current displacement value.
[0009] This invention is simple and low-cost, allowing inspectors to visually view values during inspections and calibrate platform data using visual scale values. Adding negative values to the vector displacement sensor's scale allows for direct reading even when the measured pipeline experiences reverse displacement. Furthermore, it enables circuit switching in cases of sudden, excessive settlement, preventing gas leaks and improving the safety of gas usage.
[0010] As a preferred technical solution of this utility model, the scale is provided with millimeter scale, which is divided into positive and negative scale. In the initial state, the tail end of the scale needle points to the 0 mark of the scale.
[0011] By adopting the above technical solution, adding negative values to the scale value of the vector displacement sensor, it is possible to directly read the value even when the measured pipeline exhibits reverse displacement.
[0012] As a preferred embodiment of this utility model, the vector displacement sensor is provided with a fixing part, and the reset spring is connected between the fixing part and the telescopic rod.
[0013] As a preferred embodiment of this utility model, the fixing part includes a fixing plate fixedly connected to the vector displacement sensor, the fixing plate is provided with a plurality of hanging holes, the telescopic rod is provided with a joint part, and the return spring is hung between the hanging holes and the joint part.
[0014] As a preferred embodiment of this utility model, the connector includes a mounting plate fixed to the telescopic device and a connecting head. One reset spring is provided on each side of the vector displacement sensor, and both are positioned between the fixed plate and the mounting plate.
[0015] By adopting the above technical solution, and by setting a reset spring, the scale needle can be made to accurately indicate the settlement value.
[0016] In a preferred embodiment of this invention, the joint is connected to the first flange of the main road compensator via a connecting rod.
[0017] As a preferred technical solution of this utility model, the switching mechanism includes a bypass pipe with a bypass compensator on it. One end of the bypass pipe is connected to the end of the main pipe away from the main compensator, and the other end is connected to the main pipe through a switching valve. The switching valve is located on the main pipe outside the second flange near the main compensator. It also includes a linkage component between the scale needle and the switching valve.
[0018] As a preferred embodiment of the present invention, the linkage assembly includes a linkage rod disposed on a scale needle and a driven block disposed on a switching valve, wherein the linkage rod is attached to the driven block.
[0019] As a preferred embodiment of this utility model, the end of the linkage rod is provided with an overlapping portion, which contacts the driven block.
[0020] As a preferred embodiment of this utility model, the extension and retraction of the bypass compensator is greater than that of the main road compensator.
[0021] By adopting the above technical solution, when the settlement suddenly increases, the linkage rod can drive the switching valve to switch to a bypass pipeline with a larger expansion range, preventing gas leakage, and also facilitating the replacement of compensators, etc.
[0022] The working principle and beneficial effects of this application are as follows:
[0023] 1. Add a scale needle to the existing vector displacement sensor and laser engrave millimeter scales on the surface of the vector displacement sensor. The top and bottom are positive and negative values, and the middle is 0. After installation, the scale needle needs to be fixed at the 0 value position. When the monitored object changes displacement, it will drive the scale needle to move. The mark that the arrow of the scale needle points to is the current displacement value.
[0024] 2. This utility model is simple and low-cost. Inspectors can visually view the values during inspections, and the platform data can also be calibrated using visual scale values. Adding negative values to the scale values of the vector displacement sensor allows for direct reading even when the measured pipeline experiences reverse displacement. Furthermore, in cases of sudden, excessive settlement, the system can be rerouted to prevent gas leaks and improve the safety of gas usage.
[0025] 3. When the settlement suddenly increases, the linkage rod can drive the switching valve to switch to a bypass pipeline with a larger expansion range to prevent gas leakage, and also facilitate the replacement of compensators, etc. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0034] like Figures 1-4 As shown, this embodiment provides a device for a visual reading vector displacement sensor 100, including a vector displacement sensor 100, on which a visual displacement reading mechanism is provided; the visual displacement reading mechanism includes a scale 110 laser-engraved on the front of the vector displacement sensor 100, a scale needle 140 fixed to the telescopic rod 130 of the vector displacement sensor 100 by a fixing screw 120, and a return spring 150 disposed between the vector displacement sensor 100 and the telescopic rod 130; it also includes a switching mechanism 200 disposed on the scale needle 140.
[0035] The basic principle of this embodiment is as follows: A scale needle 140 is added to the original vector displacement sensor 100, and millimeter scales are laser-engraved on the surface of the vector displacement sensor 100, with positive and negative values at the top and bottom and 0 value in the middle. After installation, the scale needle 140 needs to be fixed at the 0 value position. When the monitored object changes displacement, it drives the scale needle 140 to move. The scale point that the arrow of the scale needle 140 points to is the current displacement value.
[0036] This invention is simple and low-cost, allowing inspectors to visually view values during inspections and calibrate platform data using visual scale values. Adding negative values to the scale of the vector displacement sensor 100 enables direct reading even when the measured pipeline experiences reverse displacement. Furthermore, it allows for circuit switching in case of sudden, excessive settlement, preventing gas leaks and improving the safety of gas usage.
[0037] Reference Figure 2 and Figure 3 In this embodiment, the scale 110 is provided with millimeter scale, which is divided into positive and negative scale. In the initial state, the tail end of the scale needle 140 indicates the 0 mark of the scale 110. Adding a negative value to the scale value of the vector displacement sensor 100 can make it possible to read directly when the measured pipe has reverse displacement.
[0038] For easy fixation, a fixing part is provided on the vector displacement sensor 100. The return spring 150 is connected between the fixing part and the telescopic rod 130. Specifically, the fixing part includes a fixing plate 160 fixedly connected to the vector displacement sensor 100. The fixing plate 160 is provided with multiple hanging holes 170. The telescopic rod 130 is provided with a connector part 180. The return spring 150 is hooked between the hanging holes 170 and the connector part 180.
[0039] Reference Figures 2-4 The connector 180 includes a mounting plate 191 fixed to the telescopic device and a connector 192. The reset spring 150 is provided on both sides of the vector displacement sensor 100, and is located between the fixing plate 160 and the mounting plate 191. By setting the reset spring 150, the scale needle 140 can be accurately positioned to indicate the settlement value.
[0040] Looking back Figure 1The connector 180 is connected to the first flange 410 of the main compensator 400 via a connecting rod 193. The switching mechanism 200 of this embodiment includes a bypass pipe 210, on which a bypass compensator 220 is provided. One end of the bypass pipe 210 is connected to the end of the main pipe 300 away from the main compensator 400, and the other end is connected to the main pipe 300 via a switching valve 230. The switching valve 230 is located on the main pipe 300 outside the second flange 420 of the main compensator 400. The mechanism also includes a linkage assembly located between the scale needle 140 and the switching valve 230.
[0041] The linkage component includes a linkage rod 240 mounted on the scale needle 140 and a driven block 250 mounted on the switching valve 230. The linkage rod 240 overlaps the driven block 250, and the end of the linkage rod 240 is provided with an overlap portion 260, which contacts the driven block 250.
[0042] The extension range of the bypass compensator 220 is greater than that of the main compensator 400. When the settlement suddenly increases, the linkage rod 240 can drive the switching valve 230 to switch to the bypass pipeline 210 with a larger extension range to prevent gas leakage and facilitate the replacement of compensators.
[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
