[0024] In a further embodiment, referring to Figure 3-Figure 4The driving mechanism 5 includes a rotating block 51 and a connecting pipe 52. The upper end of the fixed seat 4 is rotatably connected to the rotating block 51, the upper end of the rotating block 51 is fixedly connected to the connecting pipe 52, the upper end of the connecting pipe 52 is fixedly connected to the main pipe 53, and the main pipe 53 is provided with four groups and is equidistantly distributed on the side wall of the main pipe 53. The lower end of the outer wall of the main pipe 53 is fixedly connected to the auxiliary pipe 54, and the upper end of the auxiliary pipe 54 is fixedly connected to the guide block 541. The guide block 541 is located inside the main pipe 53. The outer diameter of the main pipe 53 is larger than the outer diameter of the auxiliary pipe 54.

[0025] In this embodiment, high-pressure inert gas is input into the connecting pipe 52, and the inert gas flows to the main pipe 53 and is discharged from the end, so that the auxiliary pipe 54 on the left generates negative pressure, which can suck the electrolyte gas into the end of the main pipe 53 and discharge it into the interior of the detection machine body 3 for detection. The main pipe 53 on the rear side and the inert gas will remove the air in the pipeline and blow away the impurities in the pipeline. The auxiliary pipe 54 on the right side will suck the cleaning solvent into the main pipe 53 through negative pressure, and the main pipe 53 and the auxiliary pipe 54 will be cleaned by the cleaning solvent. The main pipe 53 on the front side will dry the inside of the main pipe 53 through the inert gas, and the auxiliary pipe 54 will suck in a large amount of air through negative pressure, which also achieves the drying effect. Then, the other main pipes 53 and auxiliary pipes 54 can be cleaned during detection, thereby saving cleaning time and improving the detection efficiency of the electrolyte gas.

[0026] In a further embodiment, referring to Figure 4 A fixing frame 55 is fixedly connected to the side wall of the rotating block 51 , and one end of the fixing frame 55 away from the rotating block 51 is fixedly connected to the auxiliary pipe 54 .

[0027] In this embodiment, the auxiliary pipe 54 is fixed by the fixing frame 55 , thereby achieving the effect of fixing the main pipe 53 and preventing the main pipe 53 from being shifted when rotating.

[0028] In a further embodiment, referring to Figure 2 The side wall of the fixed seat 4 is fixedly connected to a stepping motor 57, the output shaft end of the stepping motor 57 is fixedly connected to a first gear 58, the side wall of the rotating block 51 is fixedly connected to a second gear 56, and the first gear 58 and the second gear 56 are meshed with each other.

[0029] In this embodiment, the stepper motor 57 is started to drive the first gear 58 to rotate. Since the first gear 58 and the second gear 56 are engaged with each other, the second gear 56 is driven to rotate. The rotation of the second gear 56 drives the rotating block 51 to rotate. The rotation of the rotating block 51 drives the connecting pipe 52 to rotate. The rotation of the connecting pipe 52 drives the main pipe 53 to rotate, and then the main pipe 53 and the auxiliary pipe 54 in different states are moved to the next step. The stepper motor 57 is set to make the rotating block 51 rotate 90 degrees each time, so that the main pipe 53 can move to the next step.

[0030] In a further embodiment, referring to Figure 5 The auxiliary mechanism 6 includes a sleeve 61 and an electrolyte tank 63. The side wall of the fixed seat 4 is slidably connected with the sleeve 61. The inner wall of the sleeve 61 is fixedly connected to the limiting block 64. The side wall of the fixed seat 4 is provided with a limiting groove 41. The limiting block 64 is located inside the limiting groove 41 and is slidably connected thereto. The outer wall of the sleeve 61 is fixedly connected with a cleaning solvent barrel 62 and an electrolyte tank 63. A reserved opening 65 is provided on the side wall of the sleeve 61. A receiving chamber 42 is provided on the side wall of the fixed seat 4. The reserved opening 65 and the receiving chamber 42 are located in the same direction as the receiving chamber 42.

[0031] In this embodiment, the cleaning solvent barrel 62 and the electrolyte tank 63 are moved upward by moving the sleeve 61 upward, so that the auxiliary pipe 54 on the left side is closer to the inside of the electrolyte tank 63, so that the electrolyte inside the electrolyte tank 63 can be sucked into the electrolyte to produce gas, and the auxiliary pipe 54 on the right side is directly immersed in the cleaning solvent inside the cleaning solvent barrel 62, so that the cleaning solvent inside the cleaning solvent barrel 62 can be extracted to clean the auxiliary pipe 54 and the main pipe 53.

[0032] In a further embodiment, referring to Figures 1-6 The upper left end of the base 1 is slidably connected to a slider 2, and a dovetail groove 21 and a storage groove 22 are provided at the lower end of the slider 2. The upper left end of the base 1 is fixedly connected to a dovetail block 12, which is located inside the dovetail groove 21 and is slidably connected thereto. The upper left end of the base 1 is fixedly connected to an electric telescopic rod 13, and the output shaft end of the electric telescopic rod 13 is fixedly connected to the inner wall of the storage groove 22. The right end of the slider 2 is fixedly connected to a push rod 23, and the upper end of the slider 2 is fixedly connected to a detection machine body 3, and an air inlet 31 is provided at the right end of the detection machine body 3.

[0033] In this embodiment, the electric telescopic rod 13 is started to drive the slider 2 to move to the right, and the slider 2 moving to the right drives the push rod 23 to move to the right. The push rod 23 moving to the right will push the sleeve 61 upward, and the slider 2 moves to the right while driving the detection machine body 3 to move to the right. The movement of the detection machine body 3 to the right drives the air inlet 31 to move to the right, so that the end of the main pipe 53 on the left is docked with the inlet, so that the gas flowing out from the end of the main pipe 53 can flow into the inside of the detection machine body 3, thereby achieving the detection effect.

[0034] In a further embodiment, referring to Figure 2 An air passage 11 is provided at the front end of the base 1 , and the air passage 11 sequentially passes through the fixed seat 4 and the rotating block 51 and is communicated with the connecting pipe 52 .

[0035] In this embodiment, high-pressure inert gas is input into the air passage 11 . The high-pressure inert gas flows inside the main pipe 53 , generating negative pressure on the auxiliary pipe 54 . At the same time, the inert gas can start cleaning the main pipe 53 .

[0036] The working principle of the present invention is as follows: by starting the electric telescopic rod 13, the slider 2 is driven to move to the right, and the slider 2 moving to the right drives the push rod 23 to move to the right, and the push rod 23 moving to the right will push the sleeve 61 upward, so that the auxiliary pipe 54 on the left is closer to the inside of the electrolyte tank 63, and the auxiliary pipe 54 on the right is directly immersed in the cleaning solvent inside the cleaning solvent barrel 62. The slider 2 moves to the right and drives the detection machine body 3 to move to the right. The detection machine body 3 moves to the right and drives the air inlet 31 to move to the right, so that the end of the main pipe 53 on the left is connected to the inlet, which is to rush high-pressure inert gas into the airway 11. The high-pressure gas is discharged from the ends of the four groups of main pipes 53 respectively. The high-pressure inert gas flows inside the main pipe 53, which will produce a pressure on the auxiliary pipe 54. Negative pressure, the auxiliary pipe 54 on the left side can suck the electrolyte gas into the end of the main pipe 53 and discharge it into the interior of the detection machine body 3 for detection, thereby achieving the detection effect, the main pipe 53 on the rear side and the inert gas will remove the air in the pipeline and blow away the impurities in the pipeline, the auxiliary pipe 54 on the right side sucks the cleaning solvent into the main pipe 53 through negative pressure, and cleans the main pipe 53 and the auxiliary pipe 54 with the cleaning solvent, thereby achieving the cleaning effect, the main pipe 53 on the front side will dry the inside of the main pipe 53 through the inert gas, and the auxiliary pipe 54 will suck a large amount of air through negative pressure, which also achieves the drying effect, and then the other main pipes 53 and auxiliary pipes 54 can be cleaned during the detection, thereby saving cleaning time and improving the detection efficiency of the gas produced by the electrolyte;

[0037] When the inspection is finished, the electric telescopic rod 13 is started to drive the slider 2 to move to the left, thereby driving the inspection machine body 3 to move to the left, so that the air inlet 31 is disconnected from the end of the main pipe 53. At this time, the stepper motor 57 is started to drive the first gear 58 to rotate. The rotation of the first gear 58 drives the second gear 56 to rotate. The rotation of the second gear 56 drives the rotating block 51 to rotate. The rotating block 51 drives the main pipe 53 to rotate, so that the dried main pipe 53 is at the leftmost end, and the other main pipes 53 are moved to the position of exhausting air, cleaning and drying steps.
