Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, in particular to seamless gas cylinder detection equipment. Background Art

[0002] Seamless gas cylinders are manufactured through a forging or drawing process, lacking welded seams and offering superior strength and safety. Due to their structural characteristics, seamless gas cylinders are commonly used to store and transport various gases, such as oxygen, hydrogen, and nitrogen, and are widely used in industry, healthcare, firefighting, and other fields. Seamless gas cylinders are typically used to store high-pressure gases. Leaks in these cylinders can cause serious accidents such as explosions or fires, so they require regular leak testing.

[0003] In existing technology, leak detection in gas cylinders typically involves injecting gas at a certain pressure into the cylinder and observing changes in the pressure gauge to determine if there is a leak. This detection method is highly efficient and has minimal error. However, this method has certain limitations: it can only determine whether a cylinder is leaking, but it is difficult to pinpoint the leak point. Therefore, there is an urgent need for a detection device that can easily locate the leak point in a gas cylinder.

[0004] Patent publication number CN109269728A discloses a gas cylinder leak detection device capable of quickly detecting leaks. The device comprises a water tank, a lifting mechanism, and a monitoring system. During use, the gas cylinder is lowered into the water tank using the lifting mechanism, and the monitoring system observes the generation of bubbles. This mechanism relies heavily on the monitoring system, its clarity, and the operator's experience to locate leaks. Furthermore, since the gas cylinder is placed vertically in the water tank, bubbles can easily migrate along the cylinder's outer wall, affecting the determination of the leak location.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example:

[0029] A seamless gas cylinder 8 detection device, such as Figure 1As shown, it includes a detection pool 1, a lifting mechanism and a clamping mechanism 6; the lifting mechanism is arranged on both sides of the detection pool 1, and a beam 7 is connected to the lifting mechanism. The lifting mechanism is used to drive the beam 7 to move up and down, and the clamping mechanism 6 is connected to the beam 7; Figure 2 As shown, the clamping mechanism 6 includes a mounting plate 15, an adjustment component, a clamping arm 18 and a clamping baffle 20; the two clamping arms 18 are symmetrically arranged at the bottom of the mounting plate 15 and are movably connected to the mounting plate 15, the adjustment component is arranged on the mounting plate 15 and connected to the two clamping arms 18, and the adjustment component is used to control the clamping arms 18 to move closer or farther away from each other; the clamping baffle 20 is arranged on one side of the bottom of the clamping arm 18; the first roller 3 and the second roller 2 are rotatably connected in the detection pool 1, and a rolling motor 4 is arranged outside the detection pool 1, and the rolling motor 4 is used to drive the first roller 3 and the second roller 2 to rotate, and the first roller 3 and the second roller 2 rotate in the same direction; as shown Figure 3 As shown, a mounting groove 21 is provided on the clamping baffle 20 , and a plurality of clamping rollers 22 are rotatably connected in the mounting groove 21 .

[0030] Among them, the lifting mechanism is mainly used to drive the crossbeam 7 and the clamping mechanism 6 to rise and fall. In this embodiment, the lifting mechanism can adopt a mechanism that can realize the lifting function, such as a cylinder, a gear rack, etc. The clamping mechanism 6 is used to clamp the gas cylinder 8, which is convenient for testing the gas cylinder 8. The combination of the clamping mechanism 6 and the lifting mechanism can put the clamped gas cylinder 8 into the detection tank 1 for testing. The adjustment component is used to control the two clamping arms 18. When the two clamping arms 18 are close to each other, the gas cylinder 8 can be clamped. When the two clamping arms 18 are away from each other, the gas cylinder 8 can be released. The clamping baffle 20 is mainly used to limit the clamped gas cylinder 8 to prevent the gas cylinder 8 from accidentally falling from between the clamping arms 18. At the same time, the clamping baffle 20 is also in contact with the gas cylinder 8 during the clamping process. The clamping roller 22 on the clamping baffle 20 is in direct contact with the gas cylinder 8 and is used to ensure that the clamped gas cylinder 8 can rotate. The rolling motor 4 is used to drive the first roller 3 and the second roller 2 to rotate. It should be noted here that the rotation direction of the first roller 3 and the second roller 2 must be the same and the rotation speed must be approximately the same, which can be achieved through belt connection, gear connection, etc. The lifting device cooperates with the clamping device to send the gas cylinder 8 into the detection tank 1, and the leakage point of the gas cylinder 8 is determined by observing whether bubbles appear on the surface of the gas cylinder 8. It should be noted that the gas cylinder 8 tested using this device is a gas cylinder 8 that has been detected and confirmed to have a leak. The device of the present utility model is intended to find the location of the leak. The lifting device and the clamping device drive the gas cylinder 8 to contact the first roller 3 and the second roller 2. The rotation of the first roller 3 and the second roller 2 drives the gas cylinder 8 to rotate. By rotating the gas cylinder 8, the entire gas cylinder 8 can be observed, which makes it easier to find the leak point of the gas cylinder 8.

[0031] In a preferred embodiment, Figure 4As shown, the lifting mechanism includes a column 10, a lifting screw 24, a limit plate 25, and a lifting connector 9.

The provision of two first rollers 3 and two second rollers 2 effectively ensures contact between the first rollers 3 and the second rollers 2 and the gas cylinder 8, thereby effectively driving the gas cylinder 8 in rotation. Further optimized, the outer sides of the first rollers 3 and the second rollers 2 are provided with anti-slip grooves that alternate horizontally and vertically.
