[0002] The diaphragm is a commonly used component of the electrolytic cell, which divides the electrolytic chamber into an anode chamber and a cathode chamber, and is used to isolate the ions generated by electrolysis and prevent the mixing of cathode and anode products. The diaphragm needs to be detected before use and after damage to confirm its gas barrier performance and leakage degree. Now, as described in a traditional detection method disclosed in a Chinese patent for an electrolytic cell diaphragm detection device (authorized publication number CN210464819U), this patented technology can simply and intuitively observe the air permeability of the electrolytic cell diaphragm, with a simple structure and low cost. However, its detection method is too rough.

[0032]

[0033] At Figure 1 、 Figure 2 、 Figures 6 to 9In the middle: A handle assembly 21 is provided at the right end of the lower surface of the support box 1, and roller assemblies 22 are provided at the four corners of the left side surface of the support box 1. The handle assembly 21 includes two mounting tubes 33 which are mounted on the lower surface of the support box 1. Two mounting blocks 34 are mounted on one side surface of the mounting tube 33.

The upper ends of the mounting columns 40 are connected to the second mounting plate 41. Two clamping columns 42 are symmetrically mounted on the upper surface of the second mounting plate 41. The clamping columns 42 movably penetrate through the upper surface of the mounting seat 38 and the lower surface of the mounting tube 33, and the clamping columns 42 are movably located inside the mounting rod 36, that is, the clamping columns 42 are clamped into the through holes on the lower surface of the mounting rod 36. A number of springs 43 are mounted on the lower surface of the second mounting plate 41. The lower ends of the springs 43 are mounted on the lower surface of the interior of the mounting seat 38;

[0034] The roller assembly 22 includes a storage seat 44 which is mounted on the left side surface of the support box 1. Strip-shaped holes 45 are formed on the front and rear side surfaces of the storage seat 44. A first fixing block 46 is mounted on the front surface of the storage seat 44 to the left of the strip-shaped hole 45. A slide plate 47 is slidably connected to the interior of the storage seat 44.

[0036] The working principle of the present invention is as follows: When detecting whether the electrolytic water hydrogen production diaphragm 24 leaks air and the degree of air leakage, the staff can open the box cover 19, then open the first flip cover 8, the second flip cover 9 and the third flip cover 7, take out the oxygen-in-hydrogen detector 10, the hydrogen-in-oxygen detector 14 and the electric wire, place the oxygen-in-hydrogen detector 10 and the hydrogen-in-oxygen detector 14 on the first flip cover 8 and the second flip cover 9 respectively, connect the first air inlet 12 and the first valve 28 with the first pipeline 29, connect the second air inlet 16 and the second valve 31 with the second pipeline, then turn on the oxygen-in-hydrogen detector 10 and the hydrogen-in-oxygen detector 14, connect the negative electrode connector 25 and the positive electrode connector 26 to the negative and positive poles of the power supply respectively. Due to the electrolysis effect, hydrogen and oxygen will be generated inside the tank body 23. Hydrogen is located on the left side of the electrolytic water hydrogen production diaphragm 24, and oxygen is located on the right side of the electrolytic water hydrogen production diaphragm 24. First, close the second valve 31 slightly to cause the liquid level on the oxygen side to drop and the gas pressure on the oxygen side to increase. At this time, the oxygen-in-hydrogen detector 10 can be used to detect the oxygen content in hydrogen. The less the oxygen content, the better the gas barrier performance of the electrolytic water hydrogen production diaphragm 24, that is, the electrolytic water hydrogen production diaphragm 24 does not leak air. Then, close the first valve 28 slightly according to the above operation, and detect the hydrogen content through the hydrogen-in-oxygen detector 14. Similarly, the less the hydrogen content, the better the gas barrier performance of the electrolytic water hydrogen production diaphragm 24, that is, the electrolytic water hydrogen production diaphragm 24 does not leak air. Through this method, the electrolytic water hydrogen production diaphragm 24 used in the electrolysis reaction can be well detected to judge whether the electrolytic water hydrogen production diaphragm 24 is qualified; when carrying the oxygen-in-hydrogen detector 10 and the hydrogen-in-oxygen detector 14, they can be placed in the support box 1 and carried through the first handle 18. It is also possible to pull down the first mounting plate 39, slide the second handle 37 to adjust its extended length, and then rotate the adjusting rod 50 to make the second fixing block 49 drive the universal wheel 48 out, so that the detection device can also be carried in a pulling or pushing manner.
