DETAILED DESCRIPTION

[0019] The air tightness detection device of the fire extinguisher cylinder is composed of a water tank 1, a lifting cylinder 2, a lifting frame 3 and a fixed inflation mechanism. The water tank 1 is filled with water. The lifting cylinder 2 is installed on the water tank 1 through a support. The piston rod end of the lifting cylinder 2 is provided with the lifting frame 3. The fixed inflation mechanism is arranged on the lifting frame 3. The lifting cylinder 2 drives the lifting frame 3 to lift, and then drives the fixed inflation mechanism and the fire extinguisher cylinder installed on the fixed inflation mechanism to lift, so that the fire extinguisher cylinder can be immersed in the water in the water tank 1. The water is used as a detection liquid to detect whether the fire extinguisher cylinder leaks. Thus, the air tightness of the fire extinguisher cylinder is detected. The fixed inflation mechanism fixes the fire extinguisher cylinder, so that the fixed inflation mechanism can drive the fire extinguisher cylinder to lift. At the same time, after the fire extinguisher cylinder is fixed, the fire extinguisher cylinder is inflated. Thus, the position of the air bubble generated by the fire extinguisher cylinder in the water is found to find the leakage point of the fire extinguisher cylinder.

[0020] The fixed inflation mechanism is composed of a ring beam 4, a clamping cylinder 5, a push head, an inflation head 6 and a support frame 7. The lifting frame 3 on the upper side of the ring beam 4 is provided with a temporary storage platform 8. The clamping cylinder 5 is installed at the bottom of the temporary storage platform 8. The piston rod of the clamping cylinder 5 is connected with the push plate 9. The two ends of the push plate 9 are movably connected with the ring beam 4 through slide rails. The push plate 9 is uniformly provided with a plurality of push heads. The ring beam 4 on the opposite side of the push head is provided with the inflation head 6 corresponding to the push head. The ring beam 4 between the push head and the inflation head 6 is provided with the support frame 7 in parallel. The support frame 7 is provided with the arc slot 10 corresponding to the push head. The clamping cylinder 5 drives the push plate 9 to move, and then drives the push head to move, so that the moving push head can cooperate with the inflation head 6 to tightly fix the fire extinguisher cylinder. The support frame 7 supports and limits the fire extinguisher cylinder, so that the port of the fire extinguisher cylinder is aligned with the inflation head 6, and the bottom of the fire extinguisher cylinder is aligned with the push head, thereby accurately clamping and fixing the fire extinguisher cylinder. The temporary storage platform 8 temporarily stores the fire extinguisher cylinders with unqualified air tightness. After accumulating a sufficient number of unqualified fire extinguisher cylinders, the unqualified fire extinguisher cylinders are processed.

[0021] The ring beam 4 on one side of the inflation head 6 is provided with the airway 11. The airway 11 is in communication with the center hole of the inflation head 6 and the gas source, so as to sequentially inflate the fire extinguisher cylinder through the gas source, the airway 11 and the center hole of the inflation head 6.

[0022] The pushing head is composed of a supporting seat 12, an extension guide rod 13, a clamping plate 14 and a buffer spring 15. The extension guide rod 13 is screwed on the supporting seat 12. The end of the extension guide rod 13 is provided with the clamping plate 14 through a sleeve 16. The buffer spring 15 is sleeved on the extension guide rod 13 between the sleeve 16 and the supporting seat 12. The supporting seat 12 is fixedly connected with the pushing plate 9. The pushing plate 9 can drive the supporting seat 12 to move during the movement, and then drive the clamping plate 14 to move through the buffer spring 15, so as to push the clamping plate 14 to abut against the bottom of the fire extinguisher cylinder and clamp the fire extinguisher cylinder between the clamping plate 14 and the inflation head 6. The buffer spring 15 buffers the clamping plate 14, so that the force between the clamping plate 14 and the fire extinguisher cylinder gradually increases, avoiding the rigid collision between the clamping plate 14 and the fire extinguisher cylinder, and effectively protecting the fire extinguisher cylinder.

[0023] A limiting shoulder 17 is arranged on the supporting seat 12. The limiting shoulder 17 limits the movement of the sleeve 16, avoids excessive compression of the buffer spring 15, and protects the buffer spring 15.

[0024] A pull rod 18 is arranged on the ring beam 4 beside the inflation head 6. The pull rod 18 is fixedly connected with the ring beam 4 on the opposite side of the inflation head 6 through the supporting frame 7 and the pushing plate 9 in sequence, so as to pull the two ends of the ring beam 4 tightly through the pull rod 18, avoiding the deformation of the ring beam 4 under stress.

[0025] When the gas tightness detection device of the fire extinguisher cylinder works, the fire extinguisher cylinders are placed in the circular arc grooves 10 of the supporting frames 7 one by one. After the fire extinguisher cylinders are placed, the clamping cylinder 5 is started to drive the fire extinguisher cylinders to move towards the inflation head 6 through the pushing plate 9, the supporting seat 12, the buffer spring 15 and the clamping plate 14 in sequence, so that the end of the fire extinguisher cylinder abuts and seals on the inflation head 6, and the fire extinguisher cylinder is clamped between the clamping plate 14 and the inflation head 6. After the fire extinguisher cylinder is clamped and fixed, the lifting cylinder 2 is started to drive the fire extinguisher cylinder to descend through the lifting frame 3 and the fixed inflation mechanism in sequence, so that the fire extinguisher cylinder is immersed in the water of the water tank 1. During the descending of the fire extinguisher cylinder, the gas source fills the fire extinguisher cylinder through the gas channel 11 and the inflation head 6. After the fire extinguisher cylinder is immersed in the water, the fire extinguisher cylinder is observed to judge the leakage point and the gas tightness of the fire extinguisher cylinder through the position of the bubbles. When there is no bubble on the fire extinguisher cylinder, the gas tightness is qualified. When there is a bubble on the fire extinguisher cylinder, the fire extinguisher cylinder has a leakage point, and the gas tightness of the fire extinguisher cylinder is unqualified.

[0026] The airtightness detection device for the fire extinguisher steel cylinder can simultaneously inflate multiple fixed fire extinguisher steel cylinders, thereby simultaneously detecting the multiple fire extinguisher steel cylinders, effectively improving the detection efficiency; and since the inflation can be directly performed after the fixation, the manual connection of the pressure-bearing hose is not needed, the detection efficiency is further improved, and the labor intensity is reduced. The push head can buffer during the fixation of the fire extinguisher steel cylinder, reduce the rigid collision on the fire extinguisher steel cylinder, effectively avoid the deformation of the fire extinguisher steel cylinder, and protect the fire extinguisher steel cylinder. The problem of low detection efficiency of the existing airtightness test device is solved.
