[0002] A hydrogen diaphragm is a membrane material with a special microporous structure and surface properties that can effectively separate hydrogen from other gases. It is widely used in fuel cells, water electrolysis to produce hydrogen, industrial exhaust gas treatment and other fields. During the production process, the hydrogen diaphragm needs to be inspected to ensure that the surface of the hydrogen diaphragm is free of defects. Therefore, a hydrogen diaphragm surface defect detector is needed.

The cross-section of the mounting frame 11 is in a U-shaped structure. The side wall of the clamping fixture 13 is provided with an anti-slip soft pad. The return spring 14 is sleeved outside the pulling rod 12. The user pulls the pulling rod 12 outwards, and the pulling rod 12 causes the return spring 14 to be compressed and the clamping fixture 13 to move. Then, the detector body 15 is placed between the clamping fixture 13 and the inner wall of the mounting frame 11. Finally, the pulling rod 12 is slowly released. Under the action of the return spring 14, the clamping fixture 13 fits against the side wall of the detector body 15, completing the quick and convenient fixing of the detector body 15, facilitating the user to quickly disassemble and assemble the detector body 15. The height of the mounting frame 11 can be adjusted by using the cylinder 10. The driving motor 6 is used to drive the transmission screw rod 7 to rotate forward or backward.

The conveying roller 2, the detector body 15, the driving motor 6, and the cylinder 10 are all connected to the control system. The motor is used to drive the conveying roller 2 to rotate, so as to convey the hydrogen diaphragm. After the detector body 15 detects a defect, the conveying roller 2 stops operating and marks the defective part.

The clamping plate 21 is slidably arranged on the inner wall of the clamping frame 17. Place the clamping frame 17 on the top of the fixing frame 1 and make it contact with the inner wall of the fixing frame 1. Then rotate the threaded rod 20. Under the limitation of the limiting block 19, the rotation of the threaded rod 20 causes the threaded rod 20 itself to move. The movement of the threaded rod 20带动夹固板21移动,直至夹固板21与固定架1侧壁贴合,在夹持架17的配合下,完成对竖板18、固定板5等结构的安装固定,同时便于使用人员对整体装置的拆装检修。

With the cooperation of the clamping frame 17, the installation and fixation of structures such as the vertical plate 18 and the fixing plate 5 are completed, and at the same time, it is convenient for the user to disassemble, assemble, and overhaul the overall device.When using the hydrogen diaphragm surface flaw detector, the user pulls the pull rod 12 outwards by providing an adjustment component 3, and the pull rod 12 causes the reset spring 14 to be compressed and the clamping piece 13 to move, and then the detector body 15 is placed between the clamping piece 13 and the inner wall of the mounting bracket 11, and finally the pull rod 12 is slowly released. Under the action of the reset spring 14, the clamping piece 13 fits with the side wall of the detector body 15, completing the fast and convenient fixation of the detector body 15, which is convenient for the user to quickly disassemble and assemble the detector body 15. The height of the mounting bracket 11 can be adjusted by using the cylinder 10, and the drive motor 6 drives the transmission screw 7 to rotate forward or reverse. The rotation of the transmission screw 7 drives the screw nut 8 to move left or right, and the movement of the screw nut 8 drives the mounting plate 9 and the cylinder 10 to move, which can adjust the detector. The position of the main body 15 is adjusted left and right to realize convenient adjustment of the position and height of the detector main body 15, which is beneficial to the stable detection of defects on the surface of the hydrogen diaphragm.

By providing a fixing component 4, the clamping frame 17 is placed on the top of the fixing frame 1 and fits against the inner wall of the fixing frame 1, and then the threaded rod 20 is rotated. Under the limit of the limit block 19, the rotation of the threaded rod 20 causes the threaded rod 20 itself to move, and the movement of the threaded rod 20 drives the clamping plate 21 to move until the clamping plate 21 fits against the side wall of the fixing frame 1. With the cooperation of the clamping frame 17, the installation and fixation of structures such as the vertical plate 18 and the fixing plate 5 are completed, and it is convenient for users to disassemble, assemble and repair the entire device.
