[0025] Please see Figures 1 to 8 This utility model provides a technical solution: an explosion-proof intelligent gas cylinder cabinet, including a cabinet body 1 and a placement rack 11 inside. A second placement compartment 3 is located in the middle of the interior of the cabinet body 1, and first placement compartments 2 are symmetrically located on both sides of the second placement compartment 3. The placement rack 11 is fixedly installed inside the first placement compartments 2 and the second placement compartments 3. The placement rack 11 includes an L-shaped frame 12, a first limiting mechanism 13, and a second limiting mechanism 14. The L-shaped frame 12 is fixedly installed inside the first placement compartments 2 and the second placement compartments 3. A placement groove 15 is formed at the top of the bottom end of the L-shaped frame 12. Both the first limiting mechanism 13 and the second limiting mechanism 14 include a fixing seat 19 and an L-shaped frame 14. The L-shaped frame 12 includes a rod 20, a horizontal plate 21, and an adjusting plate 23. An adjusting mechanism is located inside one side of the top of the L-shaped frame 12.

The second limiting mechanism 14 is mounted on the right side of the front of the lower end of the L-shaped frame 12 via a fixing seat 19. The two fixing seats 19 are respectively fixedly mounted on the front end of the slider 18 and the front side wall of the lower end of the L-shaped frame 12. One end of the L-shaped rod 20 is rotatably mounted inside the fixing seat 19. A limiting block 24 is fixedly mounted on one end of the L-shaped rod 20 corresponding to the position of the fixing seat 19. The horizontal plate 21 A horizontally fixed L-shaped rod 20 is mounted on the front end of the horizontal plate 21. An adjusting screw 22 is screwed into the interior of the horizontal plate 21. The rear end of the adjusting screw 22 is rotatably mounted inside the front end of the adjusting plate 23. The adjusting plate 23 is located on the rear side of the horizontal plate 21. An arc-shaped groove is formed at the rear end of the adjusting plate 23. The slider 18 can be adjusted by raising and lowering it using a handwheel and a lifting screw 17. The slider 18 drives the fixed base 19, L-shaped rod 20, horizontal plate 21, and adjusting plate 23 to rise and fall synchronously. The horizontal plate 21 and the adjusting plate 23 can be moved to the front of the upper end of the gas cylinder at different heights. The adjusting plate 23 can be adjusted by adjusting the adjusting screw 22 so that it can clamp and limit the upper and lower ends of the gas cylinder, thereby improving the stability of the gas cylinder. Furthermore, by rotating and adjusting the horizontal plate 21, the adjusting plate 23 and the L-shaped rod 20, the first limiting mechanism 13 and the second limiting mechanism 14 can be moved away from the front of the gas cylinder, making it easier to take the gas cylinder out.

[0028] When using this explosion-proof intelligent gas cylinder cabinet, it can be installed outdoors via support legs 7 to avoid affecting the laboratory. The cabinet contains a first storage compartment 2 and a second storage compartment 3, which can hold more gas cylinders and allow for the categorization and storage of the gas types stored in the cylinders (e.g., nitrogen, hydrogen, and natural gas). A combustible gas detector (model GTYQ-VT625) can detect the concentration of combustible gases inside the first or second storage compartment 2 or 3. This detector can detect multiple combustible gases. A PLC controller is installed inside the second storage compartment 3. Combustible gas detectors, axial flow fans, and other components are electrically connected to the PLC controller. When the combustible gas detector detects excessive combustible gas levels inside the first storage compartment 2 or the second storage compartment 3, it controls and activates the axial flow fan. The louvers and axial flow fan facilitate ventilation of the first and second storage compartments 2 and 3, ensuring the removal of combustible gas and guaranteeing the safety of the gas cylinder cabinet. The lifting screw 17 is adjusted by rotating a handwheel according to the height of the gas cylinder. The lifting screw 17 is screwed onto the slider 1. 8. The slider 18 slides downward inside the slide groove 16. The slider 18 drives the first limiting mechanism 13 to descend and adjust to the moving height through the fixed seat 19. Magnets are provided inside the two sides of the limiting block 24 at the contact positions with the fixed seat 19. The fixed seat 19 is made of iron. Rotate the horizontal plate 21 and the adjusting plate 23 outward to adjust the horizontal plate 21 and the adjusting plate 23 from a horizontal state to a vertical state. Place the bottom end of the gas cylinder inside the placement groove 15, so that the gas cylinder is placed against the outer wall of the L-shaped frame 12. Rotate the horizontal plate 21, the adjusting plate 23 and the L-shaped rod 20 in the opposite direction to adjust the horizontal plate 21 and the adjusting plate 23 to the front side of the top and bottom ends of the gas cylinder. Furthermore, the horizontal plate 21 and the adjusting plate 23 are limited by the action of the fixed seat 19, the limiting block 24, and the magnet. The rear side wall of the adjusting plate 23 is provided with a rubber layer. By rotating the adjusting screw 22, the adjusting plate 23 is held in place to prevent it from rotating. The adjusting screw 22 drives the adjusting plate 23 to move closer to the gas cylinder and squeeze it. This facilitates the improvement of the stability of the gas cylinder through the cooperation of the first limiting mechanism 13, the second limiting mechanism 14, and the placement groove 15, making it highly practical. When it is necessary to remove the gas cylinder, simply rotate the adjusting screw 22. The adjusting screw 22 drives the adjusting plate 23 to separate from the gas cylinder and rotates the horizontal plate 21 and the adjusting plate 23 to both sides.
