Description

Technical Field

[0001] This utility model belongs to the field of power pipeline technology, and in particular relates to a corrosion detection device for boiler PL power pipelines. Background Technology

[0002] As a critical component for transporting high-temperature, high-pressure media, PL power pipelines operate in harsh environments for extended periods, facing severe corrosion challenges. With prolonged use, the media within the PL power pipeline, such as high-temperature steam and corrosive chemicals, continuously erode the pipeline's inner walls. Simultaneously, the outer wall of the pipeline may also be affected by surrounding environmental factors, such as humid air, chemical gas leaks, and condensation due to temperature differences, further contributing to corrosion. Pipeline corrosion not only reduces the pipeline's strength and pressure-bearing capacity, leading to energy leaks and economic losses, but in severe cases, it can even trigger catastrophic accidents such as explosions and fires, posing a significant threat to personnel safety and production facilities.

[0003] Traditional methods for corrosion detection in boiler PL power pipelines have many limitations. Common non-destructive testing methods, such as ultrasonic testing and radiographic testing, often require the testing equipment to be fixed at specific locations on the pipeline using complex tooling, making the operation cumbersome and time-consuming. Moreover, most existing detectors are fixed designs, and once installed, their detection angle and height are difficult to adjust. This means that only a specific, fixed area of ​​the pipeline can be inspected, failing to comprehensively cover the entire circumference of the pipeline and different height levels. This easily leads to blind spots, resulting in the inability to promptly and accurately detect potential corrosion hazards, significantly reducing the reliability and effectiveness of the inspection.

[0004] To address this issue, we provide a boiler PL power pipeline corrosion detection device to solve the problem that most of the detectors mentioned above are fixed designs, and once installed, their detection angle and height are difficult to adjust. This means that they can only detect a fixed local area of ​​the pipeline and cannot fully cover the entire circumference of the pipeline or different height levels. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion detection device for boiler PL power pipelines. Through the action of the detection strip, which can rotate 360°, it can conduct all-round detection around the pipeline, completely eliminating detection blind spots and ensuring that the corrosion of the pipeline's circumferential surface can be accurately detected, thus comprehensively understanding the pipeline's corrosion status. When the detection strip rotates, the detectors on it can collect data from different angles. These multi-directional data are analyzed and processed by the CPU to more accurately determine the corrosion location, solving existing problems.

[0006] To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model is a corrosion detection device for boiler PL power pipeline, including a base, a bracket fixed on the upper surface of the base, and a baffle fixed at one end of the bracket;

[0007] A limit strip is fixed on one side of the baffle.

[0008] A sliding groove is fixed on the upper surface of the base, a positioning plate is fixed on the upper surface of the base, and a threaded tube is fixed inside the positioning plate;

[0009] The threaded tube has a threaded rod inside, and a transmission rod is fixed at one end of the threaded rod.

[0011] The slider is slidably connected to the slide groove;

[0012] A connecting plate is fixed to the top of the slider, a motor is fixed to one side of the connecting plate, a movable rod is fixed to the output shaft of the motor, and several first transmission blocks are evenly fixed to the outside of the movable rod.

[0013] A detection strip is rotatably connected between the two baffles, and several second transmission blocks are fixed on the outer side of the detection strip;

[0014] Several detectors are fixed to the inner wall of the detection strip, and a CPU is fixed to the upper surface of the base.

[0015] The present invention is further configured such that: the first transmission block and the second transmission block are meshed and connected, and the detection strip has a semi-circular arc structure;

[0016] The two detection strips can form a circular ring structure.

[0017] The present invention is further configured such that: a first positioning hole is opened at one end of the detection strip;

[0018] The other end of the detection strip is fixed with a mounting plate, and the surface of the mounting plate has a second positioning hole.

[0019] The first positioning hole and the second positioning hole are fixed together by bolts.

[0020] The present invention is further configured such that: limit grooves are opened on both sides of the detection strip;

[0021] The limiting strip has an arc-shaped structure and is slidably connected to the limiting groove.

[0022] The present invention is further configured such that: an installation groove is formed on the upper surface of the base, and an adjusting rod is movably connected inside the installation groove.

[0023] The present invention is further configured such that: an adjustment plate is fixed to the bottom of the adjustment rod, and a caster wheel is fixed to the end of the adjustment plate away from the adjustment rod.

[0024] The present invention is further configured such that: the surface of the adjusting rod is provided with a plurality of fixing grooves, and a reinforcing plate is inserted through the fixing grooves;

[0025] Both the reinforcing plate and the base have fixing holes on their surfaces, and screws are threaded into the fixing holes.

[0026] This utility model has the following beneficial effects:

[0027] 1. This utility model utilizes a detection strip that can rotate 360° to perform omnidirectional inspection around the pipeline, completely eliminating blind spots and ensuring that corrosion on the pipeline's circumference can be accurately detected, providing a comprehensive understanding of the pipeline's corrosion status. As the detection strip rotates, the detectors on it collect data from different angles. This multi-directional data, analyzed and processed by the CPU, can more accurately determine the location of corrosion. In other words, when corrosion occurs at a point on the pipeline, the signal changes detected from different angles help the system more precisely pinpoint the exact location of the corrosion point, providing accurate information for subsequent maintenance.

[0028] 2. This utility model utilizes an adjustable rod to flexibly adjust the height of the pipe according to its actual height. When encountering a pipe at a higher position, the base is raised to allow the detection strip to reach the detection position smoothly. For a lower pipe, the base height is lowered to ensure that the detection device fits snugly against the pipe for detection, thus ensuring that pipes of different heights can be effectively detected and expanding the applicability of the detection device.

Specific Implementation Example 1

[0043] Please see Figure 1-7This utility model relates to a corrosion detection device for boiler PL power pipelines, comprising a base 1, a bracket 2 fixed to the upper surface of the base 1, a baffle 3 fixed to one end of the bracket 2, a limit strip 4 fixed to one side of the baffle 3, a sliding groove 5 fixed to the upper surface of the base 1, a positioning plate 6 fixed to the upper surface of the base 1, a threaded tube 7 fixed inside the positioning plate 6, a threaded rod 8 threadedly connected inside the threaded tube 7, a transmission rod 9 fixed to one end of the threaded rod 8, a bearing 10 fixed to one end of the transmission rod 9, a slider 11 fixed to the outer ring of the bearing 10, and a slider 11 slidably connected to the sliding groove 5. A connecting plate 12 is fixed to the top of block 11, a motor 13 is fixed to one side of the connecting plate 12, a movable rod 14 is fixed to the output shaft of the motor 13, and several first transmission blocks 15 are evenly fixed to the outside of the movable rod 14; a detection strip 16 is rotatably connected between the two baffles 3, and several second transmission blocks 17 are fixed to the outside of the detection strip 16; several detectors 18 are fixed to the inner wall of the detection strip 16, and a CPU 19 is fixed to the upper surface of the base 1; wherein the detectors 18 include ultrasonic sensors, electromagnetic sensors and resistance sensors, and all detectors 18 are electrically connected to the CPU 19.

[0044] Specifically, the first transmission block 15 and the second transmission block 17 are meshed and connected, and the detection strip 16 has a semi-circular arc structure; the two detection strips 16 can form a circular ring structure.

[0045] Furthermore, a first positioning hole 20 is opened at one end of the detection strip 16; a mounting plate 21 is fixed at the other end of the detection strip 16, and a second positioning hole 22 is opened on the surface of the mounting plate 21; the first positioning hole 20 and the second positioning hole 22 are fixed by bolts; a limit groove 23 is opened on both sides of the detection strip 16; the limit strip 4 has an arc-shaped structure, and the limit strip 4 is slidably connected to the limit groove 23.

[0046] The operation process of this embodiment is as follows: When the device is in use, the power is turned on and the motor 13 is started; the output shaft of the motor 13 drives the movable rod 14 to rotate, and the first transmission block 15 on the outer side of the movable rod 14 rotates accordingly; since the first transmission block 15 is engaged with the second transmission block 17 on the outer side of the detection strip 16, the rotation of the first transmission block 15 will drive the second transmission block 17, causing the detection strip 16 to rotate around the rotation connection point with the baffle 3; during the rotation of the detection strip 16, the detector 18 on its inner wall, which includes an ultrasonic sensor, an electromagnetic sensor and a resistance sensor, will detect the pipe; the detector 18 transmits the detected signal to the CPU 19 fixed on the upper surface of the base 1, C The PU19 analyzes and processes the data to determine whether corrosion exists in the pipeline, as well as the degree and location of corrosion. The detection strip 16 can rotate 360°, enabling omnidirectional detection around the pipeline, completely eliminating blind spots and ensuring that corrosion on the pipeline's circumference can be accurately detected, providing a comprehensive understanding of the pipeline's corrosion status. As the detection strip 16 rotates, the detectors 18 on it can collect data from different angles. This multi-directional data is analyzed and processed by the CPU19 to more accurately determine the location of corrosion. That is, when corrosion occurs at a certain point in the pipeline, the signal changes obtained from different angles can help the system more accurately pinpoint the specific location of the corrosion point, providing an accurate basis for subsequent maintenance. Specific Implementation Example 2

[0048] Please see Figure 1-3 Based on the first specific embodiment, the upper surface of the base 1 has a mounting groove 24, and an adjusting rod 25 is movably connected inside the mounting groove 24.

[0049] Specifically, an adjustment plate 26 is fixed to the bottom of the adjustment rod 25, and a caster wheel 27 is fixed to the end of the adjustment plate 26 away from the adjustment rod 25.

[0050] Furthermore, the surface of the adjusting rod 25 has several fixing grooves 28, and a reinforcing plate 29 passes through the inside of the fixing grooves 28; both the surface of the reinforcing plate 29 and the base 1 have fixing holes 30, and screws 31 are threaded into the fixing holes 30.

[0051] The operation process of this embodiment is as follows: Before using the device, adjust the height of the device according to the position and height of the pipe. That is, pull the adjusting rod 25 out of the mounting groove 24 of the base 1, and insert the reinforcing plate 29 into the fixing groove 28 of the appropriate position according to actual needs. Adjust the extension length of the adjusting rod 25 so that the caster wheel 27 contacts the ground and supports the device to ensure the stability of the device. Use the reinforcing plate 29 to pass through the fixing groove 28 on the adjusting rod 25, and then fix the reinforcing plate 29 to the base 1 with screws 31 to prevent the adjusting rod 25 from shaking. After that, install the semi-circular arc-shaped detection strip 16 on the pipe, and fix the first fixing at one end of the detection strip 16. Align the positioning hole 20 with the second positioning hole 22 on the mounting plate 21 at the other end, and tighten it with bolts to make the detection strip 16 wrap around the outside of the pipe. Since the height difference of the boiler PL power pipe is large during actual installation, the height adjustment rod 25 can be set to flexibly adjust according to the actual height of the pipe. When encountering a pipe at a higher position, the base is raised so that the detection strip 16 can reach the detection position smoothly. For a lower pipe, the height of the base is lowered so that the detection device can fit closely to the pipe for detection, ensuring that pipes of different heights can be effectively detected, thus expanding the applicable range of the detection device.
