[0002] At present, the automated measurement of the voltage in the electrolyzer chamber of the water electrolysis hydrogen production equipment requires the use of cables connected to each plate of the electrolyzer, and then the cables are connected to the voltage measuring device. However, the surface of the electrolyzer plates is smooth, and the thickness of the plates is generally less than 10 mm. Therefore, it is difficult to drill holes in the plates, and improper operation may cause leakage in the electrolyzer. The wires are connected to the plates using magnets, conductive glue, etc. The high temperature and magnetic field during the operation of the electrolyzer will demagnetize the magnets and cause the conductive glue to fall off. Among them, the wires on the surface of the electrolyzer are not firmly fixed, which may cause a short circuit in the chamber and sparks.

By leading out the plate voltage of the electrolytic cell and connecting a wire to a voltage collection device, the problem that it is difficult to lead out the wire from the surface voltage of the electrolytic cell can be solved.

[0020] like Figure 1 As shown, Figure 1 A schematic diagram showing the structure of a voltage connection device for a chamber of an electrolytic cell for producing hydrogen by water electrolysis according to an embodiment of the utility model.

[0021] In the figure, a voltage connection device for a water electrolysis hydrogen production electrolyzer chamber includes: a spring probe assembly 10 and a spring probe fixture 20;

[0025] In the embodiment of the utility model, a group of spring probe fixtures 10 are fixed on the profile rail to form a voltage collection rail assembly of the water electrolysis hydrogen production electrolytic cell chamber.

[0026] In the first implementation manner of the embodiment of the utility model, the connection hole structure for fixing the probe fixture and the introduction cable is far away from the connection part of the spring probe fixture, and the number of the connection hole structures is at least 2.

[0027] In the embodiment of the utility model, the material of the spring probe fixture is insulating, high temperature resistant and corrosion resistant.

[0028] Furthermore, the bridge fixing mode is adopted, and the voltage collection rail assembly is fixedly installed in the bridge.
