Technical Field

[0001] The utility model relates to the technical field of steel drum detection equipment, in particular to a helium detection device. Background Technique

[0002] Helium detection is a method of detecting the airtightness of products through a helium detector. By detecting whether helium gas leaks into the vacuum space through the helium detector, the airtightness of the product to be detected is judged. In production, a helium detector is commonly used to detect the airtightness of steel drums.

[0003] The patent number is "CN214583887U" and its patent name is: A steel drum helium detection device. The drawback in this published document is that: since the wall thickness of the steel drum is between 0.8 mm and 1.5 mm, that is, the wall thickness of the steel drum is relatively thin.

A barrel body 407 is arranged at the lower end of the sliding sleeve.

[0030] A pumping and sucking dual-purpose pump 5 is fixedly arranged on the outer wall of the tank body 1. A connecting head 6 is fixedly arranged on the right side of the pumping and sucking dual-purpose pump 5. A first telescopic hose 7 fixedly arranged on the right side of the connecting head 6 fixedly penetrates through the sleeve body 401. A second telescopic hose 8 is fixedly arranged on the right side of the helium leak detection device 2. One end of the second telescopic hose 8 far away from the helium leak detection device 2 penetrates through the support plate 3, and a valve 9 rotatably penetrates through the outer wall of the second telescopic hose 8. The right end of the second telescopic hose 8 fixedly penetrates through the first telescopic hose 7. A pressure sensor 10 is fixedly arranged inside the connecting head 6. A controller 11 is fixedly arranged on the outer wall of the tank body 1.

[0031] The staff first rotates the screw rod 403 forward. Through the threaded transmission of the screw rod 403 and the sleeve body 401, the bottom end of the sleeve body 401 moves to the inside of the barrel body 407 through the inlet end of the barrel body 407, and the sleeve body 401 drives the connecting plate 404 together with the conical sleeve 405 to move to the inlet end of the barrel body 407. At the same time, the connecting plate 404 together with the sealing pad 406 exerts a squeezing force on the periphery of the top of the inlet end of the barrel body 407. Through the above method, the conical sleeve 405 and the sealing pad 406 perform double sealing treatment on the inlet end of the barrel body 407. Then the staff turns on the exhaust function of the pumping and sucking dual-purpose pump 5, so as to discharge the helium gas in the tank body 1 from the connecting head 6 through the first telescopic hose 7 and into the barrel body 407 through the sleeve body 401. When the air pressure inside the barrel body 407 reaches the value set by the pressure sensor 10, the pumping and sucking dual-purpose pump 5 stops working. Then the staff opens the valve 9, so that the helium leak detection device 2 detects the helium gas in the barrel body 407.

[0034] According to the operation method in Example 1, after the blocking pad 406 exerts an extrusion force on the top surface of the barrel body 407, the staff first releases the screw 403, and then turns on the pulling function of the micro electric push rod 20. The micro electric push rod 20 drives the connecting rod 19 to control the slide plate 14 and the rack 15 to move downward along the direction of the sleeve body 401, so that the rack 15 controls the gear 13 to drive the rotating pin 12 and the rotating plate 16 to rotate, and the rotating plate 16 drives the clamping block 17 to exert an upward force on the top of the barrel body 407, that is, the upward force of the clamping block 17 and the extrusion force of the blocking pad 406 are in a relative state, preventing the blocking pad 406 from deforming the wall thickness of the top of the barrel body 407, and ensuring the stability of the blocking pad 406 and the tapered sleeve 405 being closely fitted with the barrel body 407.
