Description

Technical Field

[0001] This application relates to the field of underground pipeline safety inspection technology, and in particular to buried pipeline stress monitoring equipment. Background Technology

[0002] With the acceleration of industrialization, the construction of underground pipelines is becoming more and more widespread. The geological features along long-distance oil and gas pipelines are complex. However, due to geological changes, corrosion, external pressure and other factors, pipelines often face the risk of rupture.

[0003] Currently, traditional stress monitoring methods mostly rely on manual on-site inspections of pipelines to record the condition of the pipeline surface and environmental conditions. However, although manual inspection methods are reliable, they are time-consuming and labor-intensive, and cannot reflect the dynamic changes of pipelines in real time, making it easy to miss early signals of sudden failures. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a buried pipeline stress monitoring device, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a buried pipeline stress monitoring device, including a first mounting frame, a second mounting frame slidably connected to the bottom of the first mounting frame, a positioning structure on the outside of the second mounting frame, a movable plate slidably connected inside the first mounting frame, a detection structure at the bottom of the movable plate, the detection structure including a strain gauge, the strain gauge being fixedly connected to the movable plate, two temperature sensors symmetrically distributed on both sides of the strain gauge, the temperature sensors being fixedly connected to the movable plate, a movable structure at the top of the movable plate, a limiting structure inside the second mounting frame, an acceleration sensor and a humidity sensor sequentially mounted at the bottom of the second mounting frame, a communication module fixedly connected to the top of the first mounting frame, and a protective structure on the outside of the first mounting frame.

[0006] In a preferred embodiment, the positioning structure includes a positioning frame, which is fixedly connected to a second mounting frame. A positioning rod is slidably connected inside the positioning frame, and a first spring is sleeved on the outside of the positioning rod.

[0007] By adopting the above technical solution, the positioning rod is limited by the positioning frame, supported by the first spring, and then inserted into the interior of the first mounting frame to connect the first mounting frame and the second mounting frame, which can better connect the first mounting frame and the second mounting frame.

[0008] In a preferred embodiment, the movable structure includes a threaded rod that is rotatably connected to a movable plate and threadedly connected to a first mounting frame. A handwheel is fixedly connected to the end of the threaded rod away from the movable plate. Two telescopic limit rods are provided on the outside of the threaded rod, and the two telescopic limit rods are symmetrically installed on the surface of the first mounting frame.

[0009] By adopting the above technical solution, the threaded rod is rotated by turning the handwheel, which in turn pushes the moving plate to move. The telescopic limit rod then limits the movement of the moving plate, which allows the moving plate to move more effectively inside the first mounting frame.

[0010] In a preferred embodiment, the limiting structure includes a second spring, which is fixedly connected to a second mounting bracket. A mounting plate is fixedly connected to the top of the second spring, and the mounting plate is slidably connected to the second mounting bracket. An anti-slip plate is fixedly connected to the top of the mounting plate.

[0011] By adopting the above technical solution, the mounting plate is supported by the second spring, the anti-slip plate is fixed by the mounting plate, and the anti-slip plate is positioned by contacting the pipe surface. This allows for better positioning of the second mounting bracket.

[0012] In a preferred embodiment, the protective structure includes a wear-resistant layer, which is fixedly connected to a first mounting bracket. A corrosion-resistant layer is fixedly connected to the side of the wear-resistant layer away from the first mounting bracket. The wear-resistant layer is made of aluminum oxide, and the corrosion-resistant layer is made of polyurethane.

[0013] By adopting the above technical solution, with the wear-resistant layer made of aluminum oxide, which further enhances the wear resistance of the first mounting bracket, and the corrosion-resistant layer made of polyurethane, which further enhances the corrosion resistance of the first mounting bracket, the first mounting bracket can be better protected and its service life extended.

[0014] In a preferred embodiment, the communication module is electrically connected to the strain gauge, temperature sensor, acceleration sensor, and humidity sensor.

[0015] By adopting the above technical solution, the communication module is electrically connected to the strain gauge, temperature sensor, acceleration sensor and humidity sensor, and the communication module preprocesses the data and sends it to the monitoring center in real time. This allows for better data preprocessing and real-time transmission to the monitoring center.

[0016] In a preferred embodiment, both the first mounting bracket and the second mounting bracket have a plurality of ball bearings rotatably connected inside, and the plurality of ball bearings are distributed in a ring inside the first mounting bracket and the second mounting bracket.

[0017] By adopting the above technical solution, with a number of balls distributed in a ring inside the first mounting bracket and the second mounting bracket, and the first mounting bracket and the second mounting bracket moving on the pipe surface by the rolling of the balls, the first mounting bracket and the second mounting bracket can be moved on the pipe surface more effectively.

[0018] The beneficial effects of this application are:

[0019] 1. This buried pipeline stress monitoring equipment uses strain gauges and temperature sensors. The strain gauges detect the stress in the pipeline, the temperature sensors detect the temperature, the acceleration sensors detect the vibration, and the humidity sensors detect the humidity. The communication module preprocesses the data and sends it to the monitoring center in real time. This avoids the problems of traditional stress monitoring methods, which are time-consuming, labor-intensive, and unable to reflect the dynamic changes of the pipeline in real time, thus improving its practicality.

[0020] 2. This buried pipeline stress monitoring device, by setting up a handwheel, a threaded rod, and a telescopic limit rod, allows the threaded rod to rotate when the handwheel is turned, which in turn pushes the moving plate to move. The telescopic limit rod then limits the movement of the moving plate, and the movement of the moving plate ensures that the strain gauges and temperature sensors are in close contact with the pipeline. This avoids the problem of traditional stress monitoring methods that cannot keep the strain gauges and temperature sensors in close contact with the pipeline, thus improving practicality.

[0028] Reference Figures 1-3 A movable plate 8 is slidably connected inside the first mounting frame 1. A detection structure 7 is provided at the bottom of the movable plate 8. The detection structure 7 includes a strain gauge 71, which is fixedly connected to the movable plate 8. Two temperature sensors 72 are provided on the outside of the strain gauge 71, symmetrically distributed on both sides of the strain gauge 71. The temperature sensors 72 are fixedly connected to the movable plate 8. A movable structure 4 is provided at the top of the movable plate 8. The movable structure 4 includes a threaded rod 42, which is rotatably connected to the movable plate 8 and threadedly connected to the first mounting frame 1. A handwheel 41 is fixedly connected to the end of the threaded rod 42 away from the movable plate 8. Two telescopic limit rods 43 are provided on the outside of the threaded rod 42, which are symmetrically installed on the surface of the first mounting frame 1. By rotating the handwheel 41, the threaded rod 42 is rotated, which in turn pushes the movable plate 8 to move. The telescopic limit rods 43 then limit the movement of the movable plate 8, allowing the movable plate 8 to move more effectively inside the first mounting frame 1.

[0029] Reference Figures 1-2 The second mounting bracket 6 has a limiting structure 3 inside, which includes a second spring 33. The second spring 33 is fixedly connected to the second mounting bracket 6. A mounting plate 32 is fixedly connected to the top of the second spring 33. The mounting plate 32 is slidably connected to the second mounting bracket 6. An anti-slip plate 31 is fixedly connected to the top of the mounting plate 32. The second spring 33 supports the mounting plate 32, and the mounting plate 32 fixes the anti-slip plate 31. The anti-slip plate 31 then contacts the pipe surface to position the second mounting bracket 6, which can better position the second mounting bracket 6.

[0030] Reference Figure 4An accelerometer 9 and a humidity sensor 10 are sequentially installed at the bottom of the second mounting bracket 6. A communication module 12 is fixedly connected to the top of the first mounting bracket 1. A protective structure 5 is provided on the outside of the first mounting bracket 1. The protective structure 5 includes a wear-resistant layer 51, which is fixedly connected to the first mounting bracket 1. A corrosion-resistant layer 52 is fixedly connected to the side of the wear-resistant layer 51 away from the first mounting bracket 1. The wear-resistant layer 51 is made of aluminum oxide, and the corrosion-resistant layer 52 is made of polyurethane. By using aluminum oxide for the wear-resistant layer 51, which enhances the wear resistance of the first mounting bracket 1, and by using polyurethane for the corrosion-resistant layer 52, which enhances the corrosion resistance of the first mounting bracket 1, the first mounting bracket 1 can be better protected, and its service life can be extended.

[0031] Reference Figures 1-3 The communication module 12 is electrically connected to the strain gauge 71, temperature sensor 72, acceleration sensor 9 and humidity sensor 10. Through the electrical connection between the communication module 12 and the strain gauge 71, temperature sensor 72, acceleration sensor 9 and humidity sensor 10, the communication module 12 preprocesses the data and sends it to the monitoring center in real time, which can better preprocess the data and send it to the monitoring center in real time.

[0032] Reference Figures 1-2 Both the first mounting bracket 1 and the second mounting bracket 6 have several balls 11 rotatably connected inside. The balls 11 are arranged in a ring inside the first mounting bracket 1 and the second mounting bracket 6. By having the balls 11 arranged in a ring inside the first mounting bracket 1 and the second mounting bracket 6 roll, the first mounting bracket 1 and the second mounting bracket 6 can move on the pipe surface more effectively.

[0033] Working principle: The first mounting bracket 1 and the second mounting bracket 6 are respectively fitted onto the outside of the pipe to be inspected. The positioning bracket 23 limits the positioning rod 21, and the first spring 22 supports the positioning rod 21. The positioning rod 21 is then inserted into the inside of the first mounting bracket 1, connecting the first mounting bracket 1 and the second mounting bracket 6. Several ball bearings 11 are distributed in a ring inside the first mounting bracket 1 and the second mounting bracket 6. The rolling of the ball bearings 11 causes the first mounting bracket 1 and the second mounting bracket 6 to move on the surface of the pipe. The second spring 33 supports the mounting plate 32, and the mounting plate 32 fixes the anti-slip plate 31. The anti-slip plate 31 is then... The first mounting bracket 1 and the second mounting bracket 6 are positioned against the pipe surface. Then, the threaded rod 42 is rotated by rotating the handwheel 41. The rotation of the threaded rod 42 pushes the moving plate 8 to move. The telescopic limit rod 43 limits the moving plate 8. The moving plate 8 moves to make the strain gauge 71 and the temperature sensor 72 fit tightly against the pipe. The strain gauge 71 detects the stress of the pipe. The temperature sensor 72 detects the temperature of the pipe. The acceleration sensor 9 detects the vibration of the pipe. The humidity sensor 10 detects the humidity of the pipe. The communication module 12 preprocesses the data and sends it to the monitoring center in real time.
