[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: an explosion-proof magnetic float level gauge, including an explosion-proof box 1, a sliding column 2 slidably connected inside the explosion-proof box 1, a pull tab 3 fixedly connected to the outer wall of the sliding column 2, a sliding plate 4 fixedly connected to the outer wall of the sliding column 2, the outer wall of the sliding plate 4 slidably connected to the inside of the explosion-proof box 1, a connecting column 5 fixedly connected to the outer wall of the sliding plate 4, the outer wall of the connecting column 5 slidably connected to the inside of the explosion-proof box 1, a connecting piece 6 fixedly connected to the outer wall of the connecting column 5, the outer wall of the connecting piece 6 slidably connected to the inside of the explosion-proof box 1, a spring 7 fixedly connected to the outer wall of the connecting piece 6, the outer wall of the spring 7 fixedly connected to the inside of the explosion-proof box 1, a locking block 8 fixedly connected to the outer wall of the sliding plate 4, the outer wall of the locking block 8 slidably connected to the inside of the explosion-proof box 1, an explosion-proof door 9 abutting against the outer wall of the explosion-proof door 9, a sealing ring 10 provided on the outer wall of the explosion-proof door 9, the outer wall of the sealing ring 10 fitting against the inner wall of the explosion-proof box 1, and a rotating assembly provided inside the explosion-proof box 1;

[0024] Specifically, both the explosion-proof box 1 and the explosion-proof door 9 are made of titanium alloy. Titanium alloy has higher strength and corrosion resistance, making it suitable for harsh environments. The explosion-proof box 1 supports the sliding column 2, and the sliding column 2 fixes the pull tab 3. Pulling the pull tab 3 allows the sliding column 2 to slide stably inside the explosion-proof box 1. The sliding column 2 also fixes the sliding plate 4, allowing it to slide synchronously against the inner wall of the explosion-proof box 1. The sliding plate 4 fixes the connecting column 5, which connects the sliding plate 4 and the connecting piece 6. Sliding the sliding plate 4 causes the connecting piece 6 to slide synchronously. The spring 7 is installed between the connecting piece 6 and the connecting piece 6. Inside the explosion-proof box 1, the spring 7 is compressed by the sliding of the connecting piece 6, and the spring 7 has a rebound function. When it is not compressed, it will push the connecting piece 6 to slide in the opposite direction through its own rebound. The slide plate 4 fixes the locking block 8, so that the locking block 8 slides synchronously through the sliding of the slide plate 4. By sliding the locking block 8 into or out of the explosion-proof door 9, the position between the explosion-proof box 1 and the explosion-proof door 9 can be fixed or disassembled. The outer wall of the explosion-proof door 9 is provided with a sealing ring 10. The best material of the sealing ring 10 can be selected according to different usage environments. Through its design of tightly fitting with the inner wall of the explosion-proof box 1, a seal can be formed, thereby improving the explosion-proof performance.

[0025] Reference Figure 2 and Figure 4 The rotating assembly includes a fixed plate 11, the outer wall of which is fixedly connected to the inside of the explosion-proof box 1. A threaded column 12 is rotatably connected inside the fixed plate 11. A rotating block 13 is fixedly connected to the top of the threaded column 12. A threaded block 14 is threadedly connected to the outer wall of the threaded column 12. A limit plate 15 is slidably connected inside the threaded block 14. The outer wall of the limit plate 15 is fixedly connected to the inside of the explosion-proof box 1. A sliding seat 16 is fixedly connected to the outer wall of the threaded block 14. A first rotating shaft 17 is rotatably connected inside the sliding seat 16. One end of a rotating plate 18 is fixedly connected to the outer wall of the first rotating shaft 17. A second rotating shaft 19 is fixedly connected to the other end of the rotating plate 18. A slider 20 is rotatably connected to the outer wall of the second rotating shaft 19. A limit strip 21 is slidably connected inside the slider 20. The outer wall of the limit strip 21 is fixedly connected to the inside of the explosion-proof box 1. A fixing ring 22 is fixedly connected to the outer wall of the slider 20. The outer wall of the fixing ring 22 abuts against the liquid level gauge body 23.

[0026] Specifically, the top of the explosion-proof box 1 has a through slot to facilitate the rotation of the rotating block 13. The rotating block 13 fixes the threaded post 12, allowing the threaded post 12 to rotate synchronously with the rotating block 13. The fixing plate 11 is fixed inside the explosion-proof box 1 and supports the threaded post 12, providing stable support for the rotation of the threaded post 12. The threaded post 12 and the threaded block 14 are threadedly connected, allowing the threaded block 14 to slide synchronously with the rotation of the threaded post 12. The limiting plate 15 is fixed inside the explosion-proof box 1 and supports and limits the threaded block 14, preventing deviation during sliding. The threaded block 14 fixes the sliding seat 16 and allows the sliding seat 16 to slide synchronously. The sliding seat 16 supports the first rotating shaft 17. The rotating plate 18... The first rotating shaft 17 serves a fixing function, allowing the rotating plate 18 to rotate synchronously through the sliding of the first rotating shaft 17. The rotating plate 18 also serves a fixing function for the second rotating shaft 19. The slider 20 supports the second rotating shaft 19, thus driving the slider 20 to slide. The limiting strip 21 is fixed inside the explosion-proof box 1 to limit the sliding of the slider 20 and prevent deviation during the sliding process. The slider 20 fixes the fixing ring 22, thereby driving the fixing rings 22 on both sides to slide synchronously. The inner wall of the fixing ring 22 is designed to be fully engaged with the outer wall of the level gauge body 23. The level gauge body 23 can be locked and fixed through the fixing ring 22. The threaded column 12 has a self-locking characteristic, so the position of the level gauge body 23 can always remain stable.

[0027] Reference Figure 1 and Figure 2 The explosion-proof door 9 has a viewing window 24 inside, and a handle 25 is fixedly connected to the outer wall of the explosion-proof door 9;

[0028] Specifically, the liquid level gauge body 23 can be observed in real time through the viewing window 24. The liquid level gauge body 23 is a relatively mature existing technology, and no improvement has been made to it in this utility model. Therefore, the liquid level gauge body 23 will not be described in detail. The explosion-proof door 9 plays a role in fixing the handle 25. By pulling the handle 25, the explosion-proof door 9 can be easily pulled out from the inside of the explosion-proof box 1, so that the inside of the explosion-proof box 1 can be inspected and maintained.

[0029] Working principle: When the magnetic level gauge is needed, the level gauge body 23 is installed and placed between the fixing rings 22. Rotating the rotating block 13 drives the threaded column 12 to rotate. When the threaded column 12 rotates, it drives the threaded block 14 on the outer wall to slide. During the sliding of the threaded block 14, the sliding seat 16 and the first rotating shaft 17 will slide simultaneously. The sliding of the first rotating shaft 17 will push the rotating plate 18 to rotate. During the rotation of the rotating plate 18, the slider 20 will slide on the outer wall of the limit strip 21 through the second rotating shaft 19. During the sliding of the slider 20, the fixing rings 22 will slide simultaneously. By adjusting the distance between the two fixing rings 22, they can be made to fit tightly with the level gauge body 23, thereby fixing the level gauge body 23 inside the explosion-proof box 1. This achieves the effect of easy and quick installation in the designated position, maintaining stability during operation, and reducing measurement errors caused by displacement.

[0030] After installing the level gauge body 23, install and fix the explosion-proof box 1 and explosion-proof door 9. Both the explosion-proof box 1 and explosion-proof door 9 are designed to be explosion-proof. Pulling the pull tab 3 causes the sliding column 2 to slide inside the explosion-proof box 1. When the sliding column 2 slides, it will cause the sliding plate 4 to slide. During the sliding process, the sliding plate 4 will cause the connecting column 5 and connecting piece 6 to slide simultaneously, and will compress the spring 7 during the sliding process. When the sliding plate 4 slides, it will also cause the locking block 8 on the other side to slide. At this time, align the explosion-proof door 9 and the sealing ring 10 with the explosion-proof box 1, and release the pull tab 3. At this time, the spring 7 will push the locking block 8 into the explosion-proof door 9 through its own rebound, fixing the explosion-proof box 1 and explosion-proof door 9. The tight fit between the explosion-proof box 1 and the explosion-proof door 9 forms a seal, improving the explosion-proof effect. The quick installation and disassembly mechanism ensures that the explosion-proof box 1 and the explosion-proof door 9 are always installed in the same position. Simultaneously, the sealing ring 10 assists in sealing, effectively preventing gas leakage and guaranteeing explosion-proof performance. This magnetic float level gauge not only facilitates quick and easy installation to a designated position and maintains stability during operation, reducing measurement errors caused by displacement, but also ensures that the explosion-proof box 1 and the explosion-proof door 9 are always installed in the same position through a quick installation and disassembly mechanism. Furthermore, the sealing ring 10 assists in sealing, effectively preventing gas leakage and guaranteeing explosion-proof performance.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
