Description
Technical Field
[0001] This utility model relates to the field of corrosion detection technology, and in particular to a corrosion probe for pipeline corrosion monitoring. Background Technology
[0002] Pipeline corrosion monitoring is a crucial technical aspect in the industrial sector, particularly in industries such as petroleum, chemical, and natural gas, where the safe and stable operation of pipelines directly impacts production efficiency and personnel safety. As pipelines age, corrosion becomes a major factor affecting pipeline safety. Therefore, real-time monitoring and early warning of pipeline corrosion are essential for preventing leaks, reducing production losses, and ensuring personnel safety. With advancements in sensor and data processing technologies, modern pipeline corrosion monitoring technology can achieve real-time online monitoring. By monitoring and analyzing the internal corrosion status of pipelines in real time, potential corrosion hazards can be detected promptly, providing a scientific basis for pipeline maintenance and management.
[0003] Corrosion detection clips are an important tool for corrosion monitoring. By fixing a specially designed metal plate to the end of the probe and inserting it into the pipeline, the probe simulates the pipeline's corrosive environment, thereby enabling real-time monitoring of pipeline corrosion. The clips can directly reflect the degree and rate of corrosion inside the pipeline, providing direct evidence for pipeline maintenance and management. Existing corrosion detection clips are usually fixed to the probe clip holder with multiple bolts, and then the clip is inserted into the pipeline for detection. The clips are usually disposable, so they need to be frequently disassembled and replaced. Traditional clip installation and disassembly operations are time-consuming and labor-intensive, and replacement is inconvenient, affecting the overall detection efficiency. At the same time, the end of the clip needs to be drilled with mounting holes and bolt adapters, which not only requires calibration of the mounting holes during installation, but also increases the processing and manufacturing costs.
[0004] Therefore, it is necessary to provide a corrosion probe for pipeline corrosion monitoring to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this invention is to provide a corrosion probe for pipeline corrosion monitoring, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems: A corrosion probe for pipeline corrosion monitoring includes a base, a solid plug threaded to the inner wall of the base, a sealing ring between the base and the solid plug, a hanging bracket fixed to one end of the solid plug, an end cap fixed to the end of the hanging bracket away from the solid plug, and a mounting base fixed to the end of the end cap away from the hanging bracket. The mounting base has a cavity inside, and a rotating assembly and a clamping assembly are provided inside the mounting base. The hanging plate is clamped and connected inside the mounting base through the cooperation of the rotating assembly and the clamping assembly.
[0007] As a further embodiment of this invention, the sealing ring has a trapezoidal cross-section.
[0008] As a further embodiment of this utility model, the clamping assembly includes a partition plate fixed to the inner wall of the mounting base and located in the middle of the mounting base. The mounting base is provided with two clamping plates located on both sides of the partition plate and arranged parallel to the partition plate. The ends of the two hanging pieces are respectively inserted between the clamping plates and the partition plate, and between the clamping plates and the inner wall of the mounting base. The hanging pieces are clamped and fixed by synchronously adjusting the clamping plates.
[0009] As a further embodiment of this utility model, a rubber pad is attached and fixed to the side of the clamp near the hanging piece.
[0010] As a further embodiment of this utility model, the rotating assembly includes a nut sleeve fixed inside the side wall of the mounting base, a threaded rod connected to the nut sleeve, a protruding plate fixed to the end of the clamping plate away from the opening end of the mounting base, two protruding plates rotatably connected to a column rod, and the end of the threaded rod located inside the mounting base rotatably connected to the column rod.
[0011] As a further embodiment of this utility model, an end plate is fixed to one end of the threaded rod located outside the mounting base, and a rib is fixed to the side of the end plate. The rib is provided in multiples and the multiple ribs are distributed in a ring.
[0012] As a further embodiment of this utility model, the end of the base is threadedly connected with a protective cap to protect the end of the solid plug.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By using a rotating and clamping assembly, the ends of two hanging plates are simultaneously clamped, allowing for quick and easy installation of the two hanging plates into the mounting base. The hanging plates are then inserted into the pipeline for corrosion detection. This eliminates the need for the traditional method of fixing the hanging plates by rotating bolts, and also eliminates the need for drilling mounting holes on the ends of the hanging plates. This also reduces the need for thread alignment with mounting holes in traditional installation, thus reducing the punching process for the hanging plates and lowering manufacturing costs. The installation process is greatly simplified, and the efficiency of hanging plate installation, removal, and replacement is significantly improved, making corrosion detection operations more convenient. Furthermore, the rotating and clamping assembly can clamp and fix hanging plates of different sizes within a certain range, effectively improving overall versatility and enhancing its applicability and flexibility. 2. The connection gap between the solid plug and the base is sealed by a sealing ring with a trapezoidal cross-section. The trapezoidal cross-section of the sealing ring allows for more effective transmission of the compressive force between the solid plug and the base, reducing the compressive force required for the sealing ring to achieve a good seal. At the same time, the trapezoidal cross-section of the sealing ring has better elasticity, can better adapt to structural deformation, and can better adapt to and fit the surface of the sealing component, improving the adaptability of the sealing component, achieving excellent sealing performance, effectively improving sealing performance, and better preventing media leakage.

[0016] The present invention will be further described below with reference to the embodiments.
[0017] Please see Figure 1-5This utility model provides a corrosion probe for pipeline corrosion monitoring, including a base 2, a solid plug 3 threadedly connected to the inner wall of the base 2, a sealing ring 7 between the base 2 and the solid plug 3, a hanging plate bracket 4 fixed to one end of the solid plug 3, an end head 10 fixed to the end of the hanging plate bracket 4 away from the solid plug 3, and a mounting base 6 fixed to the end of the end head 10 away from the hanging plate bracket 4. The mounting base 6 has a cavity inside, and a rotating component 8 and a clamping component 9 are arranged inside the mounting base 6. The hanging plates 5 are clamped and connected inside the mounting base 6 by the rotating component 8 and the clamping component 9. In use, the ends of the two hanging plates 5 are inserted into the mounting base 6, and the ends of the two hanging plates 5 are clamped synchronously by the rotating component 8 and the clamping component 9. This allows for the quick and easy installation of two mounting plates 5 into the mounting base 6. The mounting plates 5 are then inserted into the pipe for corrosion detection. This eliminates the need for the traditional method of fixing the mounting plates 5 with bolts, and also eliminates the need to drill mounting holes at the ends of the mounting plates 5. This also reduces the need for thread alignment with mounting holes, thus reducing the punching process for the mounting plates 5 and lowering manufacturing costs. Furthermore, it eliminates the need for complex disassembly and reinstallation steps, greatly simplifying the installation process and improving the efficiency of mounting plate installation, disassembly, and replacement. This makes corrosion detection operations more convenient. Additionally, the rotating component 8 and clamping component 9 can be used to clamp and fix mounting plates 5 of different sizes within a certain range, effectively improving overall versatility and enhancing its applicability and flexibility.
[0018] Further as Figure 1 and Figure 2 As shown, it is worth noting that the sealing ring 7 has a trapezoidal cross-section. The trapezoidal cross-section of the sealing ring 7 seals the connection gap between the solid plug 3 and the base 2. The trapezoidal cross-section of the sealing ring 7 allows for more effective transmission of the compressive force between the solid plug 3 and the base 2, reducing the compressive force required for the sealing ring 7 to achieve a good seal. At the same time, the trapezoidal cross-section of the sealing ring 7 has better elasticity, can better adapt to structural deformation, and can better adapt to and fit the surface of the sealing component, improving the adaptability of the sealing component, achieving excellent sealing performance, effectively improving sealing performance, and better preventing media leakage.
[0019] Further as Figure 3 , Figure 4 and Figure 5As shown, it is worth noting that the clamping assembly 9 includes a partition 903 fixed to the inner wall of the mounting base 6 and located in the middle of the mounting base 6. The mounting base 6 has two clamping plates 901 located on both sides of the partition 903 and parallel to it. The ends of the two hanging pieces 5 are inserted between the clamping plates 901 and the partition 903, and between the clamping plates 901 and the inner wall of the mounting base 6, respectively. The hanging pieces 5 are clamped and fixed by synchronously adjusting the clamping plates 901. In specific operation, the ends of the two hanging pieces 5 are inserted into the mounting base 6 and placed between the clamping plates 901 and the partition 903, and between the clamping plates 901 and the inner wall of the mounting base 6. The rotating assembly 8 drives the two clamping plates 901 to move synchronously in the same direction, thereby clamping the ends of the two hanging pieces 5 together. The two hanging plates 5 are clamped together and quickly fixed into the mounting base 6. The hanging plates 5 are then inserted into the pipe for corrosion detection. This eliminates the need for the traditional method of fixing the hanging plates 5 by rotating bolts, and also eliminates the need to drill mounting holes at the ends of the hanging plates 5. This also reduces the need for thread alignment with mounting holes in traditional installation, thus reducing the punching process for the hanging plates 5 and lowering the manufacturing cost. The installation process of the hanging plates 5 is greatly simplified, and the efficiency of installation, removal and replacement of the hanging plates 5 is effectively improved, making corrosion detection operations more convenient. At the same time, the rotating component 8 and the clamping component 9 can be used to clamp and fix hanging plates 5 of different sizes within a certain size range, effectively improving the overall versatility and enhancing its applicability and flexibility.
[0020] Further as Figure 4 and Figure 5 As shown, it is worth noting that a rubber pad 902 is attached and fixed to the side of the clamping plate 901 near the hanging piece 5. The area of the rubber pad 902 is equal to the area of the side of the clamping plate 901. In actual operation, the rubber pad 902 not only prevents the clamping plate 901 from damaging the end of the hanging piece 5, but also increases the clamping friction of the clamping plate 901 on the end of the hanging piece 5, effectively improving the clamping stability.
[0021] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth noting that the rotating assembly 8 includes a nut sleeve 802 fixed inside the side wall of the mounting base 6. A threaded rod 803 is threadedly connected to the nut sleeve 802. A protruding plate 806 is fixed on the end of the clamping plate 901 away from the opening end of the mounting base 6. The two protruding plates 806 are rotatably connected to the column rod 801. The end of the threaded rod 803 located inside the mounting base 6 is rotatably connected to the column rod 801. In specific operation, by rotating the threaded rod 803, the threaded rod 803 drives the column rod 801 to move, thereby driving the two protruding plates 806 to move synchronously through the column rod 801. In turn, the protruding plates 806 drive the two clamping plates 901 to move synchronously, so that the clamping plates 901 clamp the end of the hanging piece 5.
[0022] The solution has the following working process: The ends of the two hanging plates 5 are inserted into the mounting base 6 and placed between the clamping plate 901 and the partition plate 903, and between the clamping plate 901 and the inner wall of the mounting base 6. By rotating the threaded rod 803, the threaded rod 803 drives the column rod 801 to move. The column rod 801 drives the two protruding plates 806 to move synchronously. In turn, the protruding plates 806 drive the two clamping plates 901 to move synchronously. Thus, the two clamping plates 901 clamp the ends of the two hanging plates 5 synchronously, thereby quickly fixing the two hanging plates 5 into the mounting base 6. Then, the hanging plates 5 are inserted into the pipeline for corrosion detection.
[0023] Further as Figure 4 and Figure 5 As shown, it is worth noting that an end plate 804 is fixed to one end of the threaded rod 803 located outside the mounting base 6. A rib 805 is fixed to the side of the end plate 804. Multiple ribs 805 are provided and are arranged in a ring. In actual operation, the end plate 804 facilitates the rotation of the threaded rod 803, making operation convenient. The multiple ribs 805 increase the friction when rotating the end plate 804 and prevent slippage.
[0024] Further as Figure 1 As shown, it is worth noting that the end of the base 2 is threaded with a protective cap 1 to protect the end of the solid plug 3.
[0025] In summary: By simultaneously clamping the ends of the two hanging plates 5 using the rotating assembly 8 and the clamping assembly 9, the two hanging plates 5 are quickly and securely installed into the mounting base 6. The hanging plates 5 are then inserted into the pipe for corrosion detection. This eliminates the need for the traditional method of fixing the hanging plates 5 with bolts, and eliminates the need for drilling mounting holes on the ends of the hanging plates 5. It also eliminates the need for thread alignment during traditional installation, reducing the punching process for the hanging plates 5 and lowering manufacturing costs. Furthermore, it eliminates the need for complex disassembly and reinstallation steps, greatly simplifying the installation process and significantly improving the efficiency of hanging plate installation and replacement, making corrosion detection operations more convenient. Additionally, the rotating assembly 8 and clamping assembly 9 can clamp and fix hanging plates 5 of different sizes within a certain range, effectively… The overall versatility is improved, enhancing its applicability and flexibility. The end plate 804 facilitates the rotation of the threaded rod 803, making operation convenient. Multiple ribs 805 increase the friction when rotating the end plate 804, preventing slippage. The trapezoidal cross-section of the sealing ring 7 seals the connection gap between the solid plug 3 and the base 2. The trapezoidal cross-section of the sealing ring 7 allows for more effective transmission of the compressive force between the solid plug 3 and the base 2, reducing the compressive force required for a good seal. At the same time, the trapezoidal cross-section of the sealing ring 7 has better elasticity, can better adapt to structural deformation, and can better adapt to and fit the surface of the sealing component, improving the adaptability of the sealing element, achieving excellent sealing performance, effectively improving sealing performance, and better preventing media leakage.
