Abstract
Description
Technical Field
[0001] This utility model relates to the field of corrosion detection technology for storage tanks, specifically a corrosion safety detection device for chemical storage tanks. Background Technology
[0002] Storage tanks are widely used in industrial production to store various liquid and gaseous media such as petroleum and chemical raw materials. The impurities and moisture contained in the media on the inner wall of the storage tank often contain a large amount of chlorides, sulfides, etc. After long-term sedimentation, they will form a strong electrolyte solution, resulting in electrochemical corrosion. Therefore, it is necessary to conduct corrosion inspections on the storage tanks regularly to detect potential corrosion defects in a timely manner and ensure the safe operation of the storage tanks. During corrosion inspections, staff will use handheld ultrasonic testing equipment to inspect the storage tanks.
[0003] When using a handheld ultrasonic probe, the traditional two-handed operation mode of holding the probe and terminal separately has significant limitations. The hand holding the terminal is completely restricted by the device, making it impossible to assist the other hand in making fine adjustments to the probe (such as calibrating the angle and controlling the application of coupling agent), and it is also difficult to simultaneously complete auxiliary actions such as pressing and supporting during the detection process. This operational constraint leads to a decrease in probe control accuracy. Especially when facing complex curved surfaces or tiny corrosion defects, the lack of coordination between both hands can easily lead to blind spots or data deviations, directly affecting the accuracy and efficiency of corrosion detection. Utility Model Content
[0004] The purpose of this invention is to provide a corrosion safety detection device for chemical storage tanks to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a corrosion safety detection device for chemical storage tanks, comprising a terminal, wherein a probe is provided at the top of the terminal;
[0006] The rear wall of the terminal is provided with an adjustment mechanism, which includes a rotating rod, a connecting block rotatably connected to the rotating rod, a strap fixedly connected to the connecting block, a support ring fixedly connected to the rotating rod, and multiple limiting rods slidably connected to the support ring. A first magnet is fixedly connected to one end of each limiting rod, and a ring is fixedly connected to the other end of each limiting rod. A spring is fixedly connected to each ring. A limiting groove is formed on the connecting block at the position corresponding to the limiting rod, and a second magnet is fixedly connected inside each limiting groove.
[0007] Preferably, the rotating rod is fixedly connected to the back wall of the terminal, and the strap is elastic.
[0008] Preferably, one end of each of the first magnets is set as the south pole, and the position of each of the second magnets corresponding to the south pole of the first magnets is set as the north pole, and each of the first magnets is magnetically connected to the corresponding second magnet.
[0009] Preferably, the first magnet is located inside the limiting groove, and the limiting groove is tapered.
[0010] Preferably, one end of each spring is fixedly connected to the support ring, and the strap has multiple ventilation grooves.
[0011] Compared with the prior art, the beneficial effects of this utility model are: by adjusting the mechanism, the terminal can be worn on the wrist, which can free the operator's hand from gripping the terminal, completely freeing the operator's hand from gripping the terminal, and enabling the operator to operate the probe with both hands. Whether it is fine-tuning the probe angle, accurately controlling the coupling force, or performing complex curved surface scanning, more refined detection actions can be achieved, significantly improving the accuracy and detection efficiency of corrosion defect identification.
[0012] During the testing process, staff can adjust the terminal display angle in advance according to their posture and observation needs. Even when pressing the probe with both hands, they can simultaneously view the results displayed on the terminal on their wrists without having to make any special movements such as looking down. This truly achieves simultaneous and efficient testing and data viewing. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4The present invention provides the following technical solution:
[0020] Example 1: A corrosion safety detection device for chemical storage tanks, including a terminal 1, with a probe 2 at the top of the terminal 1;
[0021] When in use, the staff can press the probe 2 on the location on the storage tank where corrosion needs to be detected. The probe 2 will emit high-frequency sound waves. The wall thickness change and internal corrosion defects can be judged based on the specific signal of the echo. The specific value of the echo can be obtained by observing the terminal 1.
[0022] Example 2: The technical solution of this example, which differs from that of Example 1, includes: an adjustment mechanism 3 is provided on the back wall of the terminal 1. The adjustment mechanism 3 includes a rotating rod 31, a connecting block 32 rotatably connected to the rotating rod 31, a strap 33 fixedly connected to the connecting block 32, a support ring 34 fixedly connected to the rotating rod 31, a plurality of limiting rods 35 slidably connected to the support ring 34, a first magnet 36 fixedly connected to one end of each limiting rod 35, a ring 37 fixedly connected to the other end of each limiting rod 35, a spring 38 fixedly connected to each ring 37, and a limiting groove 39 opened on the connecting block 32 at the position corresponding to the limiting rod 35. A second magnet 301 is fixedly connected inside each limiting groove 39.
[0023] The rotating rod 31 is fixedly connected to the back wall of the terminal 1. The strap 33 is elastic. One end of the first magnet 36 is set as the south pole. The second magnet 301 is set as the north pole corresponding to the south pole of the first magnet 36. The first magnet 36 is magnetically connected to the corresponding second magnet 301. The first magnet 36 is located inside the limiting groove 39. The limiting groove 39 is tapered. One end of the spring 38 is fixedly connected to the support ring 34. Multiple ventilation grooves are opened on the strap 33.
[0024] In use, the hand can be threaded through the strap 33. The elasticity of the strap 33 will tightly bind the user's wrist, freeing the hand wearing the strap 33. Both hands can then be used to operate the probe 2 for corrosion detection. Initially, the terminal 1 is symmetrically positioned with the user's arm at the same angle. This position allows the user to press the probe 2 while directly viewing the internal display on the terminal 1, achieving truly simultaneous and efficient detection and data viewing. However, this position makes it inconvenient for the user to raise their hand to view the terminal 1. If the user needs to raise their hand to view the terminal 1 before detection, the terminal 1 needs to be rotated 180° so that it crosses the user's wrist. At this point, the terminal 1 can be rotated directly, causing the rotating rod 31 to rotate. The rotating rod 31 then rotates the support ring 34 and multiple limiting rods 35. The rotation of the limiting rods 35 will all rotate the first magnet. As the terminal 1 rotates, the first magnet 36, following the rotation of the limiting rod 35, will slowly separate from the second magnet 301. Simultaneously, the first magnet 36 will continuously press against the wall of the limiting groove 39 during this rotation. As it rotates, the first magnet 36 will move towards the limiting rod 35. This movement of the first magnet 36 will cause the limiting rod 35 to move, which in turn will cause the ring 37 to move, stretching the spring 38. When the first magnet 36 moves to the outside of the limiting groove 39, one end of the first magnet 36 will abut against the outer wall of the connecting block 32. Then, the rotating first magnet 36 will follow the limiting rod 35 to rotate into another limiting groove 39. This process is repeated until the terminal 1 is rotated 180°. At this point, the operator can clearly see the display on the terminal 1 by raising their hand, similar to raising their hand to check a watch. This facilitates the detection of corrosion in different locations of the storage tank, improving the efficiency and quality of tank corrosion detection.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
