[0028] As follows, the embodiments will be further described with reference to the accompanying drawings.

[0029] As Figures 1 to 3 shown, as a preferred Embodiment 1, a leak detection device for simultaneously detecting multiple gas cylinders includes a movable small gantry 1, on which an electric hoist 101 is movably arranged. A gas cylinder hanging basket 2 is detachably hung on the hook of the electric hoist 101. Several gas cylinder bodies 5 are detachably placed in the gas cylinder hanging basket 2. The several gas cylinder bodies 5 are placed vertically and closely to save the placement space as much as possible. In the case of small length and width, more gas cylinder bodies 5 can be placed. An immersion pool 4 is arranged below the small gantry 1. The gas cylinder hanging basket 2 is lifted and lowered with the small gantry 1 through the electric hoist 101, and the gas cylinder hanging basket 2 is movably embedded in the immersion pool 4. The immersion pool 4 is filled with water whose liquid level exceeds the gas cylinder body 5. Angle-adjustable lighting mechanisms 3 are arranged on both sides of the small gantry 1, and the irradiation ends of the lighting mechanisms 3 face towards the inside of the immersion pool 4.

[0030] During use, the lifting and lowering of the gas cylinder hanging basket 2 above the immersion pool 4 is realized through the electric hoist 101 of the existing small gantry 1, so that the gas cylinder bodies 5 in the gas cylinder hanging basket 2 are lifted and lowered synchronously. During detection, the gas cylinder bodies 5 are placed into the immersion pool 4 and all the gas cylinder bodies 5 are submerged by water. After the liquid level is relatively stable, an appropriate amount of air is introduced into each gas cylinder body 5, and the bubble situation generated during the process is observed. If bubbles are generated in the gas cylinder body 5 during the whole process, there are problems of leakage and poor airtightness of the gas cylinder body 5.

[0031] The length of the gas cylinder hanging basket 2 is less than the length of the immersion pool 4, and the width of the gas cylinder hanging basket 2 is less than the width of the immersion pool 4, ensuring that the gas cylinder hanging basket 2 can be smoothly placed into the immersion pool 4. The height of the immersion pool 4 is greater than the height of the gas cylinder body 5, ensuring that the water can completely submerge the top of the gas cylinder body 5.

[0032] As a preferred embodiment 2, a notch 201 is provided on one side of the gas cylinder hanging basket 2, and an operable door 202 is provided at the notch 201. A hanging frame 205 is provided at the middle position of the gas cylinder hanging basket 2. The middle position at the top of the hanging frame 205 forms a detachable hanging connection with the hook of the electric hoist 101.

[0033] One side of the operable door 202 forms a hinge connection with the gas cylinder hanging basket 2 on the corresponding side of the notch 201 through a hinge member 203, facilitating the opening of the operable door 202. Thus, the gas cylinder body 5 can be moved into the gas cylinder hanging basket 2 through the notch 201. The other side of the operable door 202 forms a detachable bolt locking connection with the gas cylinder hanging basket 2 on the corresponding other side of the notch 201 through a bolt 204, facilitating the locking of the operable door 202 to prevent the gas cylinder body 5 from falling out of the gas cylinder hanging basket 2 during the lifting process.

[0034] There are no less than two hinge members 203, and the hinge members 203 are symmetrically arranged about the middle position of the operable door 202, ensuring the stability when the operable door 202 is opened.

[0035] There are no less than two bolts 204, and the bolts 204 are symmetrically arranged about the middle position of the operable door 202, ensuring the stability when the operable door 202 is locked.

[0036] The hanging frame 205 is in a "door" - shaped structure. The hanging frame 205 is vertically arranged at the middle position of the gas cylinder hanging basket 2. The two ends of the hanging frame 205 respectively correspond to the two opposite sides of the gas cylinder hanging basket 2 one - to - one, and the bottom parts of the two ends of the hanging frame 205 respectively form a fixed connection with the top of the middle position of the corresponding gas cylinder hanging basket 2. A lifting ring 206 is provided at the top of the middle position of the top cross - beam of the hanging frame 205. The lifting ring 206 forms a detachable hanging connection with the hook of the electric hoist 101, ensuring the lifting of the gas cylinder hanging basket 2.

[0037] The distance from the top cross - beam of the hanging frame 205 to the bottom of the gas cylinder hanging basket 2 is greater than the height of the gas cylinder body 5, facilitating the placement of the gas cylinder body 5 and preventing the gas cylinder body 5 from colliding with the hanging frame 205 during the placement process.

[0038] The gas cylinder body 5 is divided into two groups with the hanging frame 205 of the gas cylinder hanging basket 2 as the center, and the two groups of gas cylinder bodies 5 are symmetrically arranged about the hanging frame 205, ensuring the force balance of the gas cylinder hanging basket 2 and thus ensuring the stability of the gas cylinder hanging basket 2 during lifting.

[0039] Preferably, six gas cylinders can be placed in the gas cylinder body 5, which are arranged in a 2×3 array.

[0040] As a preferred embodiment 3, the lighting mechanism 3 includes a mounting base 301. The mounting base 301 is detachably and fixedly coupled to the small gantry 1 through fasteners. A flexible metal tube 302 is provided on one side of the mounting base 301 close to the immersion tank 4. A lighting lamp 303 is provided at the end of the flexible metal tube 302, and the lighting lamp 303 is fixedly coupled to the mounting base 301 through the flexible metal tube 302 in a deformable manner. The position of the lighting lamp 303 can be changed through the flexible metal tube 302 and fixed there, so as to facilitate the adjustment of the lighting lamp 303. No matter how the relative positions of the small gantry 1 and the immersion tank 4 change, the lighting lamp 303 can always illuminate the inside of the immersion tank 4, with good applicability and improved observation accuracy.

[0041] The working principle of the present utility model:

[0042] The present utility model provides a leak detection device for simultaneously detecting leaks in multiple gas cylinders. During use, the lifting of the gas cylinder hanging basket 2 above the immersion tank 4 is realized through the electric hoist 101 of the existing small gantry 1, so that the gas cylinder bodies 5 in the gas cylinder hanging basket 2 are lifted and lowered synchronously. During detection, the gas cylinder bodies 5 are placed in the immersion tank 4, and all the gas cylinder bodies 5 are submerged in water. After the liquid level is relatively stable, an appropriate amount of air is introduced into each gas cylinder body 5, and the bubble situation generated during the observation is observed. If bubbles are generated in the gas cylinder body 5 during the whole process, there are problems of leakage and poor airtightness in the gas cylinder body 5.
