During the rotation of the swing rotating block, the through rod drives the movable block to move up and down by guiding the wave groove.

Due to the small amount of liquid, when the pressure in the corrugated oil tank is large and the corrugated oil tank is shaking, the liquid is sprayed out through the leak and discolored on the blotting paper, so the leak can be clearly located. Then, the reel motor is started to wind the rolling reel to replace the blotting paper for the next test.

[0019] As there is less liquid in the corrugated oil tank, only the vertical bottom surface of the corrugated oil tank can be detected. Therefore, when it is necessary to replace the opposite surface to the blotting paper, the driving roller is started to move to the vertical rod part of the clamping rod, driving the sliding buckle block to slide and the thrust shaft to slide in the clamping sliding groove. By coordinating the rotation of the threaded rotating rod, the distance between the thrust plates is changed, so that the clamping rod can maintain the clamping of the corrugated oil tank while driving the corrugated oil tank to rotate horizontally. After that, the driving motor is started to rotate the first bevel gear to engage the second bevel gear to rotate the thrust shaft, so as to realize the vertical flipping of the corrugated oil tank. Through the above cooperation, it is possible to replace the blotting paper on different surfaces and complete the detection of different surfaces. At the same time, the flipped thrust shaft can continue to drive the vibration pendulum to flip, so as to realize the horizontal shaking and vertical shaking effect of the corrugated oil tank.

[0020] The device has a simple structure, and utilizes a small amount of liquid in the corrugated oil tank and the pressurization of a booster mechanism to spray the liquid onto blotting paper to achieve precise positioning of the leak and efficient leak detection on multiple surfaces of the corrugated oil tank. It has good practicality and economy, and is beneficial to the promotion and use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Advantageously, the sealing cone 53 is made of soft rubber material, which can better fit and seal the inner cavity of the ventilation pipe 51.

[0041] Working principle of the present invention:

[0042] The operator first hoists the corrugated oil tank 6 between the two sets of clamping rods 21, injects a small amount of liquid into the corrugated oil tank 6 through the ventilation pipe 51, starts the adjusting motor 231 to rotate and drive the threaded rotating rod 232 to rotate and push the thrust plate 23 away from the support plate 233, so that the clamping rod 21 can clamp the corrugated oil tank 6, and then starts the vibration motor 293. The vibration motor 293 rotates the rotating rod 291 to drive the vibration pendulum 292 to rotate. Under the action of the centrifugal force generated by the rotation of the vibration pendulum 292, the support plate 233 is driven to slide on the fixed slide rod 32, and the swing rotating block 572 is driven to rotate at the same time. During the rotation of the swing rotating block 572, the through rod 571 drives the movable block 56 to move up and down by guiding the wave groove 561. When the movable block 56 moves downward At the same time, the air between the sealing lifting sliding plate 563 and the sealing cone 53 is driven to pass through the through hole 564 and then continue to flow into the inner cavity of the corrugated oil tank 6 through the sealing cone 53. When the movable block 56 moves upward, the air is driven to push open the gap between the sealing ring 58 and the through hole 564 and flow into the sealing lifting sliding plate 563 and the sealing cone 53. The cycle of air replenishment and air release can be completed. During the process of increasing the pressure in the corrugated oil tank 6, the liquid is sprayed out from the gap in the corrugated oil tank 6 under pressure. Since the amount of liquid is small, when the pressure in the corrugated oil tank 6 is large and the corrugated oil tank 6 is shaking, the liquid is sprayed out through the leak and sprayed onto the blotting paper 42 to cause discoloration, so that the leak can be clearly located. After that, the reel motor 43 is started to wind the rolling reel 41 to replace the blotting paper 42 for the next detection.

[0043] Since there is less liquid in the corrugated oil tank 6, only the vertical bottom surface of the corrugated oil tank 6 can be detected. Therefore, when it is necessary to replace the opposite surface of the blotting paper 42, the driving roller 27 is started to move to the vertical rod part of the clamping rod 21, driving the sliding buckle block 28 to slide and the thrust shaft 24 to slide in the clamping sliding groove 212, and cooperating with the rotation of the threaded rotating rod 232 to change the distance between the thrust plates 23, so that the clamping rod 21 can maintain the clamping of the corrugated oil tank 6 while driving the corrugated oil tank 6 to rotate horizontally. Then, the driving motor 251 is started to rotate the first bevel gear 25 to engage the second bevel gear 252 to rotate the thrust shaft 24, so that the vertical flipping of the corrugated oil tank 6 can be achieved. Through the above-mentioned cooperation, it is possible to replace the blotting paper 42 on different surfaces to complete the detection of different surfaces. At the same time, the flipped thrust shaft 24 can continue to drive the vibration pendulum 292 to flip, so as to achieve the effect of horizontal shaking and vertical shaking of the corrugated oil tank 6.
