Description
Technical Field
[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an auxiliary tool for cleaning and maintaining gas storage tanks. Background Technology
[0002] In the industrial production sector, gas storage tanks are key equipment for storing various gases (including flammable and explosive gases, toxic and harmful gases, and inert gases). Their operating status directly affects production safety and system stability. To ensure the safe operation of gas storage tanks, regular mechanical cleaning and maintenance are essential. During this process, it is necessary to accurately detect the composition and concentration of residual gases inside the tank to avoid safety accidents such as explosions and poisoning caused by gas leaks or excessive concentrations. Portable gas detectors have thus become the core tool for ensuring operational safety in this process.
[0003] Portable gas detectors, through their built-in sensor modules, can monitor the oxygen content, combustible gas concentration, and toxic gas composition inside a tank in real time. This provides operators with a basis for determining whether the environment inside the tank meets operational standards. In practical applications, the equipment needs to be installed in different areas inside the tank to complete the detection work, and its fixing method directly affects the detection efficiency, accuracy, and operational safety.
[0004] The current methods of fixing portable gas detectors mostly rely on manual hand-holding or traditional support. While manual hand-holding is flexible, it has significant limitations. Inside gas storage tanks, the space is often quite narrow, especially in horizontal tanks or tanks with internal support structures. The operator's range of motion is restricted, and holding the detector for a long time can easily lead to arm fatigue, which in turn causes the detection probe to shake. This shaking directly affects the stability of the sensor's contact with the gas, resulting in fluctuations in the detection data and making it difficult to accurately reflect the gas concentration in a specific area inside the tank.

[0039] Please see Figure 1-4 This utility model provides a technical solution: an auxiliary tool for cleaning and maintaining a gas storage tank, comprising a housing 1 and a gas detector body 2;
[0040] A magnetic suction component is provided on the outer casing 1;
[0041] The magnetic attraction assembly includes a protective sleeve 7 and a magnetic block 8. A magnetic block groove 13 is formed on the outer wall of the rear end of the outer shell 1. Two second T-shaped block grooves 11 are formed on the upper and lower inner walls of the magnetic block groove 13. The outer wall of the magnetic block 8 is slidably connected to the interior of the magnetic block groove 13. A first limiting block groove 9 is formed on the outer wall of one side of the two protrusions at the rear end of the outer shell 1. Limiting blocks 10 are slidably connected to the interior of the two first limiting block grooves 9. The outer walls of the upper and lower T-shaped blocks of the magnetic block 8 are slidably connected to the interior of the corresponding second T-shaped block grooves 11. Two third T-shaped block grooves 14 are formed on the outer wall of the rear end of the outer shell 1. The outer walls of the T-shaped blocks on both sides of the protective sleeve 7 are slidably connected to the interior of the corresponding third T-shaped block grooves 14. 8 is located inside the protective sleeve 7. The upper two outer walls of the protective sleeve 7 are provided with second limiting block grooves 12. The ends of the two limiting blocks 10 near the second limiting block grooves 12 are slidably extended to the outside of the first limiting block groove 9 and are slidably connected to the inside of the corresponding second limiting block groove 12. The outer walls of the two protrusions at the rear end of the outer shell 1 are slidably connected with pull rods 3. The ends of the two pull rods 3 near the limiting block 10 are slidably extended to the inside of the first limiting block groove 9 and are fixedly connected to the outer wall of one side of the corresponding limiting block 10. The outer walls of the two pull rods 3 are sleeved with return springs 15. The two ends of the two return springs 15 are fixedly connected to the inner wall of the corresponding first limiting block groove 9 and the outer wall of one side of the limiting block 10, respectively.
[0042] The outer wall of the outer shell 1 has a first T-shaped block groove 6 on both sides of the front end. The outer wall of the gas detector body 2 is slidably connected to the inner front end of the outer shell 1. The outer wall of the lower end protrusion of the gas detector body 2 is slidably connected to the groove on the lower surface of the outer shell 1. A sliding limit plate 4 is slidably engaged in the sliding groove on the lower end of the outer wall of the outer shell 1. A limit sliding groove 5 is formed on the outer wall of the lower end protrusion of the gas detector body 2. The end of the sliding limit plate 4 near the limit sliding groove 5 extends slidably into the groove on the lower surface of the outer shell 1 and is slidably engaged in the groove. The outer walls of the T-shaped blocks on both sides of the gas detector body 2 are slidably connected to the corresponding first T-shaped block groove 6.
[0043] Furthermore, when using this device, first align the T-shaped blocks on both sides of the gas detector body 2 with the first T-shaped block groove 6 of the outer casing 1, and align the lower protrusion with the groove on the lower surface of the outer casing 1. Push the gas detector body 2 along the groove so that it is completely inserted into the front end of the outer casing 1. At this time, slide the sliding limiting plate 4 at the lower end of the outer casing 1 so that one end slides into the limiting slide groove 5 of the gas detector body 2, thus fixing the gas detector body 2. When disassembly is required, slide the sliding limiting plate 4 in the opposite direction to disengage it from the limiting slide groove 5, and then the gas detector body 2 can be pulled out along the first T-shaped block groove 6. Then, use the magnetism of the magnetic block 8 to pull the entire... The tool is attached to the metal inner wall of the gas storage tank, thus securing the tool.

[0044] By directly adsorbing the magnetic block 8 in the magnetic assembly to the metal inner wall of the gas storage tank, combined with the multi-position locking of the magnetic assembly, the main body 2 of the gas detector can be firmly fixed to any metal surface inside the tank. This eliminates the need for traditional brackets to find support points and assemble and debug, reducing the risk of bumps and knocks caused by handheld devices. This simplifies the operation steps, allowing a single person to complete all operations in a narrow space, greatly improving the convenience of operation.

By cooperating with the second limiting block groove 12, the positions of the protective sleeve 7 and the magnetic block 8 are locked.
[0051] Return spring 15: It is sleeved on the outer wall of the pull rod 3, and its two ends are fixedly connected to the inner wall of the first limiting block groove 9 and the outer wall of one side of the limiting block 10, respectively. In the natural state, the return spring 15 pushes the limiting block 10 out of the first limiting block groove 9 and into the second limiting block groove 12 to achieve locking.
