A control panel 4 is provided on the right side of the front of the frame 1. Clamping components 5 are provided on the left and right sides of the frame 1.
[0024] Please refer to Figure 3. In this embodiment, the testing mechanism 3 includes a first electric push rod 301 fixed to the upper surface of the frame 1 by a mounting bracket. The outer side of the output shaft of the first electric push rod 301 slides through the frame 1 and extends into the interior. A fixing rod 302 is fixed to the outer side of the output shaft of the first electric push rod 301. Two fixing discs 303 are fixed to the outer side of the fixing rod 302. Rubber sealing rings 304 are fixed to the outer sides of the upper and lower fixing discs 303. A pneumatic booster pump 305 is fixed to the left side of the upper surface of the frame 1. A fixing pipe 306 is fixed to the output end of the pneumatic booster pump 305. The bottom end of the fixing pipe 306 passes through the frame 1 and extends into the interior. The bottom end of the fixing pipe 306 is connected to a movable pipe 307. The bottom end of the movable pipe 307 is connected to a connecting pipe 308. The outer side of the bottom end of the connecting pipe 308 is connected to a first solenoid valve 309. The first solenoid valve 309 has a connecting component inside. The movable pipe 307 can deform, and its length allows the upper and lower fixing discs 303 to move up and down.
[0025] Specifically, the connecting assembly includes a first input pipe 310 connected inside the first solenoid valve 309. The bottom end of the first input pipe 310 passes through the upper fixing plate 303 and extends to the lower side. The right side of the connecting pipe 308 is connected to the second solenoid valve 311 through a pipe. The interior of the second solenoid valve 311 is connected to the second input pipe 312. The bottom end of the second input pipe 312 passes through both the upper and lower fixing plates 303 and extends to the lower side of the lower fixing plate 303. The rubber sealing ring 304 can seal the contact point between the fixing plate 303 and the container.
[0026] Specifically, pressure sensors 313 are fixed on the lower surfaces of the upper and lower fixed plates 303. The first electric push rod 301, the first solenoid valve 309, the second solenoid valve 311 and the two pressure sensors 313 are all electrically connected to the control panel 4 through wires. A limiter 6 is provided on the left side wall of the inner cavity of the frame 1. The limiter 6 includes a U-shaped frame. A sliding rod is slidably connected inside the U-shaped frame. A moving rod is slidably connected outside the sliding rod. One side of the moving rod is fixed to the front of the fixed rod 302.
[0027] It should be noted that by operating the control panel 4, the first electric push rod 301 is activated, which moves the upper and lower fixed plates 303 into the container. The rubber sealing rings 304 on the upper and lower sides can seal the container in sections. Then, the pneumatic booster pump 305, the first solenoid valve 309, and the second solenoid valve 311 can be opened by operating the control panel 4. The pneumatic booster pump 305 outputs air and delivers it into the container through the pipeline. The pressure sensors 313 on the upper and lower sides can monitor the air pressure at different sections inside the container in real time and display it on the display screen of the control panel 4. After pressure detection, the first solenoid valve 309 and the second solenoid valve 311 are closed. Then, the pressure value displayed on the display screen of the control panel 4 is checked. If there is a change, it indicates that there is a leak. Sectional detection can be performed to more accurately locate the leak.
[0028] Please refer to Figure 4. In this embodiment, the clamping assembly 5 includes second electric push rods 501 fixed to the left and right sides of the frame 1 by a mounting bracket. The outer sides of the output shafts of the second electric push rods 501 on both sides slide through the frame 1 and extend into the interior. Arc-shaped clamping plates 502 are fixed to the outer sides of the output shafts of the second electric push rods 501 on both sides. The second electric push rods 501 on both sides are controlled by a synchronous controller so that the output shafts of the second electric push rods 501 on both sides move synchronously in opposite directions or synchronously in opposite directions.
[0029] Specifically, the clamping assembly 5 is also fixed to the telescopic rods 503 on the left and right side walls of the inner cavity of the frame 1. The opposite side of the left and right telescopic rods 503 is fixedly connected to the opposite side of the left and right arc-shaped clamping plates 502. The bottom wall of the inner cavity of the frame 1 is fixed with a limit cylinder 504. The telescopic rod 503 includes a first slide rod. The first slide rod is slidably connected to a second slide rod. The second electric push rods 501 on the left and right sides are electrically connected to the control panel 4 through wires.
[0030] Specifically, those skilled in the art can control electrical components by simply programming the control panel 4, and the existing publicly available power connection technology is also common knowledge in the field. Therefore, this embodiment will not elaborate on its specific structural composition and working principle.
[0031] It should be noted that placing the container to be tested inside the limiting cylinder 504 can limit the placement of the container. Then, by operating the control panel 4, the second electric push rods 501 on both sides are started simultaneously, which drives the arc-shaped clamps 502 on both sides to move synchronously in opposite directions and clamp and fix the container.
[0032] The working principle of the above embodiments is as follows:
[0033] In use, the container to be tested is placed inside the limiting cylinder 504, which limits the container's placement. Then, by operating the control panel 4, the second electric push rods 501 on both sides are simultaneously activated, causing the arc-shaped clamping plates 502 on both sides to move synchronously in opposite directions and clamp and fix the container. After that, by operating the control panel 4, the first electric push rod 301 is activated, causing the upper and lower fixing plates 303 to move into the interior of the container. The rubber sealing rings 304 on both sides can seal the container in sections. Finally, the pneumatic booster pump 305 can be activated by operating the control panel 4. The first solenoid valve 309 and the second solenoid valve 311 are opened, and the pneumatic booster pump 305 delivers air through the pipeline to the inside of the container. The pressure sensors 313 on the upper and lower sides can monitor the air pressure at different sections inside the container in real time, and display the results on the display screen of the control panel 4. After pressure detection, the first solenoid valve 309 and the second solenoid valve 311 are closed. Then, the pressure value displayed on the display screen of the control panel 4 is checked again. If there is a change, it indicates that there is a leak. Segmented detection can be performed to more accurately locate the leak.
