[0029] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0030] Example 1

[0031] Please refer to Figure 1-4 , a detection device comprising:

[0032] Two limiting plates 1, two transmission wheels 2 are rotatably installed between the two ends of the two limiting plates 1, and the two transmission wheels 2 are connected to the same transmission belt 21. When one transmission wheel 2 rotates, the transmission of the transmission belt 21 will drive the other transmission wheel 2 to rotate, thereby realizing the reciprocating movement of the transmission belt 21. The surface of the transmission belt 21 is equidistantly fixed with a plurality of placement seats 3 for placing can bodies. The can bodies can be placed on the placement seats 3 in sequence with the help of a robotic arm, and then taken away after the inspection is completed. The top of the two limiting plates 1 is fixed with the same U-shaped frame 10, and the bottom of the limiting plate 1 is symmetrically fixed with two supporting legs 8, and the bottom of the four supporting legs 8 is fixed with the same bottom plate 9;

[0033] The driving mechanism is provided on the limiting plate 1 and is used to intermittently drive the transmission wheel 2 to rotate. The driving mechanism includes a mounting frame 5 fixedly provided on the outer wall of one of the limiting plates 1. A driving motor 6 is fixedly installed on the mounting frame 5. The output shaft of the driving motor 6 passes through the inner wall of the mounting frame 5 and is fixedly provided with a transmission gear 7. One end of one of the transmission wheels 2 passes through the outer wall of the corresponding limiting plate 1 and is fixedly provided with an intermittent gear 4. The intermittent gear 4 is engaged with the transmission gear 7. The driving motor 6 drives the transmission gear 7 to rotate, thereby driving the transmission wheel 2 to rotate intermittently through the intermittent gear 4, so that the transmission belt 21 moves intermittently to detect the can body in the placement seat 3;

[0034] The detection mechanism is provided on the U-shaped frame 10 and is used to detect the air tightness of the tank body. The detection mechanism includes an electric push rod 11 fixedly installed in the center of the top of the U-shaped frame 10. The output end of the electric push rod 11 passes through the inner wall of the U-shaped frame 10 and is fixedly provided with a detection cylinder 12. A plurality of gas sensors 13 are fixedly provided in a circular array on the inner wall of the detection cylinder 12. The model of the gas sensor 13 is SMD1003, which is used to accurately detect whether there is carbon monoxide gas leakage in the tank body. The model of the gas sensor 13 can be replaced according to the type of the detected gas. The top of the outer wall of the detection cylinder 12 is fixed with a plurality of gas sensors 13. An alarm light 14 and a buzzing alarm 15 are fixedly provided. Both the alarm light 14 and the buzzing alarm 15 are electrically connected to the plurality of gas sensors 13. A PLC controller 16 is fixedly provided on the outer wall of the U-shaped frame 10. The PLC controller 16 is connected to an external power supply and is powered by the OHR-PR10 model. The PLC controller 16 can be programmed to control the operating status of the drive motor 6, the electric push rod 11 and the gas sensor 13. The operating frequency of the electric push rod 11 can be controlled according to the time it takes for the intermittent gear 4 to rotate one circle, thereby realizing automatic detection of the tank body.

[0035] More specifically, in this embodiment, the tank bodies are placed on the placement seat 3 in sequence by a robotic arm, and then the drive motor 6 is used to drive the transmission gear 7 to rotate, thereby driving the transmission wheel 2 to rotate intermittently through the intermittent gear 4, so that the transmission belt 21 moves intermittently. Each time the transmission belt 21 stops, the PLC controller 16 controls the electric push rod 11 to operate, and covers the detection tube 12 outside the placement seat 3 located below the detection tube 12. The gas sensor 13 detects the sealing of the tank body. If a tank leak is found, the alarm light 14 lights up and the buzzing alarm 15 emits a buzzing alarm sound. At the same time, the PLC controller 16 controls the drive motor 6 to stop running so that the staff can remove the leaking tank body. It is easy to use and can improve the detection efficiency of dangerous gas packaging tanks.

[0036] This application can be used for the detection of dangerous goods storage and transportation, and can also be used in other fields applicable to this application.

[0040] Please refer to Figure 3 A plurality of auxiliary rollers 17 are rotatably installed between the two limit plates 1 to prevent the transmission belt 21 from sinking. By setting the auxiliary rollers 17 to support the transmission belt 21 at the middle end, thereby preventing it from sinking, it is beneficial to ensure the flatness of the surface of the transmission belt 21.

[0041] Please refer to Figure 2 , self-locking universal wheels 20 are fixedly installed at the four corners of the bottom of the base plate 9 to facilitate the movement of the entire device and adjust its position. Two threaded rods 19 are symmetrically fixed at the bottom of the base plate 9. The threaded rods 19 are threadedly connected to limit blocks 18. The limit blocks 18 are preferably made of rubber. After the entire device is moved to a new location, the self-locking universal wheels 20 are locked, and then the limit blocks 18 are screwed respectively to cause the limit blocks 18 to move downward until they contact the ground, thereby increasing the friction with the ground and making it difficult for the entire device to move again.
