[0008] Sealing gaskets are respectively arranged on adjacent sides of the two contact plates, and the sealing gaskets are in contact with each other.
[0009] The sealing mechanism includes a telescopic airbag, a shunt pipe and an air inlet pipe. There are two telescopic airbags. Both telescopic airbags are located on the inner wall of the positioning ring and are fixedly connected. The air inlets of the two telescopic airbags are connected to the air outlet of the shunt pipe. The air inlet of the shunt pipe is installed with the air inlet.

[0017] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.
[0018] Combined with Figures 1 to 3 The hydrogen leakage detection device for producing hydrogen by electrolysis of water comprises a positioning mechanism 1 , a sealing mechanism 2 is installed on the fixed end of the positioning mechanism 1 , and a hydrogen leak detector 3 is installed on the locking end of the positioning mechanism 1 .
[0019] The positioning mechanism 1 includes a positioning ring 101 and a tightening screw 102 . Contact plates are respectively provided at both ends of the positioning ring 101 . The two contact plates are connected by the tightening screw 102 and a nut. A sealing mechanism 2 is installed in the positioning ring 101 .
[0020] The two contact plates are respectively provided with arc-shaped grooves, and the positions of the two arc-shaped grooves correspond to each other. A hydrogen leak detector 3 is installed in the arc-shaped grooves.
[0021] Sealing gaskets are respectively arranged on adjacent sides of the two contact plates, and the sealing gaskets are in contact with each other.
[0022] The sealing mechanism 2 includes a telescopic airbag 201, a diverter pipe 202 and an air inlet pipe 203. There are two telescopic airbags 201. The two telescopic airbags 201 are both located on the inner wall of the positioning ring 101 and are fixedly connected. The air inlets of the two telescopic airbags 201 are both connected to the air outlets of the diverter pipe 202. The air inlet pipe 203 is installed in the air inlet of the diverter pipe 202. A sealing cover is provided on the air inlet pipe 203 to facilitate the staff to inflate and exhaust.
[0023] The two telescopic airbags 201 are respectively located on both sides of the arc-shaped groove, so that the detection space is in a sealed state, which facilitates the hydrogen leak detector 3 to detect hydrogen.
[0024] The hydrogen leakage detection device for producing hydrogen by electrolysis of water is described. When in use, the staff puts the positioning ring 101 on the joint of the two pipes, fixes the position of the positioning ring 101 by tightening the bolts 102 and the nuts, and inflates the two telescopic airbags 201 through the air inlet pipe 203 and the shunt pipe 202 to expand the telescopic airbags 201. The expanded telescopic airbags 201 will be in contact with the outer wall of the pipe, so that the positioning ring 101 and the outer wall of the pipe are in a sealed state. If hydrogen leaks, the hydrogen will flow in the space between the two telescopic airbags 201. The gas in the space between the two telescopic airbags 201 is detected by the hydrogen leak detector 3, which is convenient for the staff to check at any time.
