[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model.

[0026] It should be noted that, in this embodiment, the supporting mechanism is used to stably support other parts of the measuring device to ensure the stable operation of the measuring device for the alkaline electrolyzer chamber; the guiding mechanism 2 is used to provide the measuring mechanism 1 with a moving path and direction so that the measuring mechanism 1 can detect all alkaline electrolyzer chambers of all hydrogen production equipment; the measuring mechanism 1 is used to detect the temperature and voltage of the alkaline electrolyzer chamber. Specifically, the measuring mechanism 1 includes a drive motor 11, a temperature detection module, and a voltage detection module, wherein the drive motor 11 is used to provide the measuring mechanism 1 with a moving path and direction.

The explosion-proof thermocouple 13 is used to measure the temperature of the alkaline electrolyzer chamber.

The cylinder 14 is pushed forward towards the hydrogen production equipment, and the detection probe 15 moves towards the voltage detection position of the hydrogen production equipment along with the pushing direction of the second slide cylinder 14. After the voltage detection task is completed, the second slide cylinder 14 retracts, and the detection probe 15 moves away from the voltage detection position of the hydrogen production equipment along with the retraction direction of the second slide cylinder 14. The detection probe 15 is used to measure the voltage of the alkaline electrolyzer chamber. In the specific implementation of this utility model, when the measuring equipment for the alkaline electrolyzer chamber is started, firstly, the drive motor 11 drives the entire measuring mechanism 1 along the guide mechanism 2 to the detection position of the alkaline electrolyzer chamber.Then, the first slide cylinder 12 pushes the explosion-proof thermocouple 13 to the temperature detection position of the alkaline electrolytic cell chamber for temperature measurement (usually, the temperature data can be measured by placing the explosion-proof thermocouple 13 close to the alkaline electrolytic cell chamber; if the alkaline electrolytic cell chamber is equipped with a temperature measuring hole, the temperature data is measured by inserting the explosion-proof thermocouple 13 into the temperature measuring hole). The second slide cylinder 14 pushes the detection probe 15 to the voltage detection position of the alkaline electrolytic cell chamber for voltage detection (by contacting the cathode plate and anode plate of the alkaline electrolytic cell chamber with the detection probe 15, the voltage difference between the two plates is directly read). The potential difference); then, after the detection task of the alkaline electrolyzer cell is completed, the first slide cylinder 12 and the second slide cylinder 14 retract, and the explosion-proof thermocouple 13 and the detection probe 15 move away from the detection position of the alkaline electrolyzer cell; finally, the above steps are repeated until the measuring mechanism 1 has traversed all the alkaline electrolyzer cells of the hydrogen production equipment (typically, the hydrogen production equipment contains 200-300 alkaline electrolyzer cells connected in series); through the above detection process, this embodiment can measure the temperature and voltage of the alkaline electrolyzer cells to reduce the safety risks of electrolyzer operation.

Since the helical gear 19 meshes with the helical rack 22, the helical gear 19 converts the rotational motion of the drive motor 11 into linear motion along the helical rack 22, and drives the slider 20 to slide along the linear guide rail 23, thereby moving the entire measuring mechanism 1 to the detection position of the alkaline electrolysis cell chamber to perform the detection task.

The fixing bolts pass through both the first fixing holes and the second fixing holes.

[0032] It should be noted that, in this embodiment, the first support frame 5, the second support frame 6, and the third support frame 7 serve as the main support structures. They are evenly distributed at the bottom of the guide support platform 21 to bear the weight of the guide mechanism 2 and the measuring mechanism 1, thereby ensuring the stability of the overall structure of the measuring device for the alkaline electrolytic cell chamber. The support rod 8 strengthens the overall structural rigidity, preventing the support frame from deforming or bending, thus improving the overall stability of the support mechanism. The design of the anchor block 9, the first fixing hole, the second fixing hole, and the fixing bolts is to fix the entire measuring mechanism 1 for the alkaline electrolytic cell chamber to the ground, further ensuring the stability of the overall structure of the measuring device for the alkaline electrolytic cell chamber.
