Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detection of oxygen cylinders, and specifically, to an air tightness detection device for oxygen cylinders. Background Technique

[0002] Oxygen cylinders are ideal oxygen supply devices for hospitals, first aid stations, nursing homes, home care, battlefield rescue, personal health care, and oxygen supplementation in various hypoxic environments. After the production and processing of oxygen cylinders, it is necessary to detect their air tightness to avoid leakage of the stored oxygen, which affects the storage of oxygen.

[0003] After retrieval, the utility model patent with the publication number of CN217032942U discloses an air tightness detection device for oxygen cylinders, which includes a gantry. A water jacket is arranged below the gantry. An electric hoist is slidably connected to the gantry. A water jacket cover is suspended from the hook of the electric hoist. The water jacket cover includes a water jacket shell with an open top. A water jacket end cover is fixedly connected to the open position at the top of the water jacket shell. Suspension lugs are fixedly connected to both sides of the water jacket end cover, and a lifting ring is arranged between the two suspension lugs. A high-pressure joint, a pneumatic joint, and an exhaust pipe that are connected to the inside of the water jacket shell are respectively arranged on the water jacket end cover; the bottom of the water jacket shell is communicated with a gas cylinder joint. The gas cylinder joint includes a first connecting pipe and a second connecting pipe arranged coaxially. External threads are arranged on the outer walls of the first connecting pipe and the second connecting pipe. One end of the first connecting pipe is fixedly communicated with the inside of the water jacket shell, and a locking sleeve is sleeved and threadedly connected between the other end of the first connecting pipe and the second connecting pipe. This patent is relatively labor-saving, and one person can complete the connection and communication between the water jacket cover and the oxygen cylinder.

[0004] However, the above patent still has the following deficiencies: Although one person can complete the connection between the water jacket cover and the oxygen cylinder, when detecting the air tightness of multiple oxygen cylinders, it takes a certain amount of time to install and disassemble the oxygen cylinders, and the efficiency of sequentially detecting multiple oxygen cylinders is low; in addition, when the oxygen cylinder is lifted out of the water, water stains adhere to the outside of the oxygen cylinder, and direct disassembly may cause water droplets to fall onto other parts, which is not convenient for cleaning and also causes a reduction in the detection water in the water jacket, requiring adjustment. For this reason, we propose an air tightness detection device for oxygen cylinders. Content of the Utility Model

[0037] In this embodiment, it is ensured that the air blowing pipe 23 can blow air to the bottle body 9 smoothly so as to clean the water stains on the outside of the bottle body 9.

[0038] Working principle: When in use, first place a bottle body 9 directly below an external thread tube 20. Start the electric hydraulic rod 6 to drive the mounting box 7 and the external thread tube 20 to move downward. At the same time, start the second motor 14 to drive the first gear 18 to rotate. Utilize the meshing transmission between the first gear 18 and the second gear 19 to drive the rotating tube 13 and the external thread tube 20 to rotate, so that the external thread tube 20 is threadedly sleeved into the inner cavity of the internal thread port 10, and the bottle body 9 is connected below the mounting box 7. Then start the electric hydraulic rod 6 to drive the mounting box 7 and the bottle body 9 to move upward. Additionally, start the first motor 3 to drive the rotating bracket 4, the electric hydraulic rod 6, the mounting box 7 and the bottle body 9 to rotate, so that the bottle body 9 moves above the transparent water tank 11. At this time, another external thread tube 20 is placed on the other side, so that another bottle body 9 is installed on this external thread tube 20. Then start the electric hydraulic rod 6 to drive the mounting box 7 and the bottle body 9 to move downward, so that the bottom end of the bottle body 9 extends into the water in the inner cavity of the transparent water tank 11. Start the air blower pump 15 to introduce gas into the bottle body 9 from the air guide steel pipe 17, the rotary joint 16, the rotating tube 13 and the external thread tube 20, and observe whether bubbles appear on the side of the bottle body 9 located in the water, so as to detect the air tightness of the bottle body 9. Finally, start the electric hydraulic rod 6 to lift the detected bottle body 9. At this time, start the blowing pump 21 to make the water distribution ring pipe 22 and the blowing pipe 23 blow downward, so that the wind blown out by the blowing pipe 23 cleans the water stains on the side of the bottle body 9, and the water stains on the outside of the bottle body 9 fall back into the transparent water tank 11. After the water stains are cleaned, move the bottle body 9 back to its original position, move another bottle body 9 to the transparent water tank 11 for detection, and disassemble the detected bottle body 9, and that's it.
