A drive assembly 4 is fixedly connected to the right end of the rotating shaft 7 located at the rear. A support frame 5 is fixedly connected to the two support rods 3 located on the left and the two support rods 3 located on the right at their close ends. A detection assembly 6 is fixedly connected to the right side of the support frame 5. Several oil can lids 1 are provided on the upper part of the outer surface of the conveyor belt 2.

[0028] In the specific implementation process of this solution, the oil can lid 1 is first transported into the upper end of the conveyor belt 2. The support frame 5 is used to clamp the oil can lid 1. The support frame 5 can be adjusted and clamped independently according to the diameter of the oil can lid 1. Then, the drive component 4 is started, which drives the rotating shaft 7 on the same side to rotate. Under the action of the other rotating shaft 7, the conveyor belt 2 is driven to rotate. At the same time, the drive component 4 drives the detection component 6 to start operating. When the oil can lid 1 is transported to the lower part of the detection component 6, the detection component 6 contacts the oil can lid 1 to perform high voltage discharge, and the resulting arc discharge phenomenon is used to detect gas leakage.

[0029] Specifically, in order to facilitate the unloading of the oil can lid 1 and improve the efficiency of the inspection, as shown in the figure, several baffles 21 are fixedly connected at equal intervals in the middle of the outer surface of the conveyor belt 2;

[0030] Furthermore, referring to the figure, the support frame 5 includes two connecting rods 51. The upper end of the connecting rod 51 on the right is fixedly connected to a stop rod 52, and the upper end of the connecting rod 51 on the left is fixedly connected to a vertical rod 53. The right end of the vertical rod 53 is fixedly connected to several springs 54, and the right ends of the several springs 54 are jointly fixedly connected to a stop rod 55.

[0031] Further, referring to the drawings, the driving assembly 4 comprises a motor 41, the motor 41 is fixedly connected with a connecting column through the output end coupling, the connecting column extends to the right end of the same side rotating shaft 7 through the same side supporting rod 3 and is fixedly connected with the rotating shaft 7, the connecting column is rotatably connected with the same side supporting rod 3, the outer surface of the connecting column is fixedly connected with two meshing bevel gears 42, the lower end of the lower bevel gear 42 is fixedly connected with a connecting shaft 43, the lower end of the motor 41 is fixedly connected with a connecting frame through a connecting seat, and the lower end of the connecting shaft 43 extends to the lower part of the connecting frame through the connecting frame and is rotatably connected with the connecting frame;

[0032] Further, referring to the drawings, the connecting frame is fixedly connected with the same side supporting rod 3, and the connecting shaft 43 is rotatably connected with the same side supporting rod 3.

[0034] Therefore, first, the oil can cover 1 on the rear side of the device is transported to the upper end of the conveying belt 2, so that the front part of the outer surface of the oil can cover 1 is tightly attached to the front end of the same side stop bar 21, when the oil can cover 1 is placed on the upper part of the outer surface of the stop bar 21, the positive “eight” shape of the rear part of the second stop rod 55 and the first stop rod 52 allows the oil can cover 1 to be smoothly placed on the upper part of the outer surface of the conveying belt 2, if the diameter of the oil can cover 1 is greater than the distance between the second stop rod 55 and the first stop rod 52, the oil can cover 1 can be squeezed to the left side by a plurality of springs 54, so that the second stop rod 55 is close to the spring 54, so that the second stop rod 55 and the first stop rod 52 clamp the oil can cover 1, and the driving assembly 4 is started to drive a plurality of oil can covers 1 to move forward, when the oil can cover 1 moves forward, the same side stop bar 21 pushes the oil can cover 1 to move forward smoothly.

[0035] At the same time, when the oil can cover 1 is placed on the upper end of the conveying belt 2, it can automatically adjust under the action of the oil can cover 1, so that a plurality of oil can covers 1 on the upper part of the outer surface of the conveying belt 2 are arranged according to the position of the stop bar 21, and when the oil can cover 1 is placed on the front part of the device, it directly falls into the next process instrument in the front part, which facilitates the discharging of the oil can cover 1 and improves the detection efficiency.

[0036] Specifically, in order to ensure the continuity of the device detection and improve the detection efficiency, referring to the drawings, the detection assembly 6 comprises an L-shaped plate 64, a bidirectional screw 63 rotatably connected with the left end of the L-shaped plate 64 through a connecting block, a connecting rod 65 fixedly connected with the lower end of the bidirectional screw 63, the lower end of the connecting rod 65 extending to the lower end of the L-shaped plate 64 and rotatably connected with the L-shaped plate 64, a high-voltage discharge method leak detector 62 threadedly connected with the outer surface of the bidirectional screw 63, and a contact assembly 61 fixedly connected with the lower end of the high-voltage discharge method leak detector 62.

[0037] Further, referring to the drawings, the L-shaped plate 64 is fixedly connected with the same side connecting rod one 51, and the connecting rod two 65 is connected with the connecting shaft 43 through two belt pulleys and a transmission belt;

[0038] Further, referring to the drawings, the contact assembly 61 includes a sleeve 611 fixedly connected with the lower end of the high-voltage discharge method leak detector 62, a sliding rod 614 slidably connected with the inner surface of the sleeve 611, a spring two 613 fixedly connected with the top wall of the inner surface of the sleeve 611 at the upper end of the sliding rod 614, an electric wire 612 fixedly connected with the upper end of the sliding rod 614, the electric wire 612 being arranged inside the spring two 613, the upper end of the electric wire 612 extending into the high-voltage discharge method leak detector 62 through the high-voltage discharge method leak detector 62, and the lower end of the electric wire 612 extending out of the sliding rod 614 through the sliding rod 614;

[0039] The working principle of the high-voltage discharge method leak detector 62 is to detect the leakage of gas or liquid by using the arc discharge phenomenon generated by high-voltage discharge. Based on the principle of electricity, high-voltage charges are applied to stimulate the leaks in the system, thereby detecting the existence of leaks. When high-voltage charges pass through the leaks, obvious discharge phenomena such as arc, spark or current will occur. These discharge phenomena can be detected and analyzed by special equipment to determine the location and severity of the leaks.

[0040] By observing the display on the equipment, if there is discharge phenomenon, record the current, time and other parameters of the discharge, and perform data analysis. According to the detection result, it is judged whether the oil can lid 1 exists leakage. If discharge phenomenon is detected and data analysis shows that there is leakage, further processing is required.

[0041] Therefore, when the motor 41 is started, the connecting column is driven to rotate, the same side rotating shaft 7 is driven to rotate, the conveying belt 2 is driven to rotate under the action of the rotating shaft 7 at the front, and the several oil can lids 1 are driven to move forward one by one.

[0042] When the motor 41 is started, the connecting column is driven to rotate, the same side rotating shaft 7 is driven to rotate, the conveying belt 2 is driven to rotate under the action of the rotating shaft 7 at the front, and the several oil can lids 1 are driven to move forward one by one.

[0043] In addition, when the slide rod 614 touches the oil can cover 1 downward, the device can touch the lowest position due to the slight difference in height or different shapes of the oil can cover 1, and if the change is needed, the bidirectional screw rod 63 needs to be redesigned and changed, if the oil can cover 1 is higher, when the slide rod 614 touches downward, the slide rod 614 will slide slightly to the inside of the sleeve shell 611 and press the spring two 613, and the electric wire 612 is used for discharge detection, at this time, the oil can cover 1 continues to move forward under the action of the same side of the blocking strip 21, the slide rod 614 will slide slightly to the upper end of the oil can cover 1, and then move upward under the action of the bidirectional screw rod 63, the slide rod 614 will reset under the action of the spring two 613, and prepare for the next time to detect the next oil can cover 1, so as to realize continuous detection and improve the detection efficiency.

[0044] It should be particularly pointed out that the specific installation mode of the motor 41, the connection mode of the circuit and the control method used in the utility model all belong to the conventional design, and the utility model will not be described in detail.
