[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5A hydrogen leak detector includes a mounting base 1, on which an electric push rod 2 is arranged. Specifically, a circular assembly groove is opened on the mounting base 1, and the electric push rod 2 is embedded in the assembly groove. A clamping base 201 is arranged at the moving end of the electric push rod 2.

[0025] Furthermore, in order to facilitate the staff to take it, the bottom of the mounting base 1 is threadedly connected with a handle.

[0026] Specifically, the bottom of the mounting seat 1 has a thread groove, and the surface of the grip rod has a thread structure adapted to the thread groove.

[0027] Furthermore, a button switch is provided on the mounting base 1 , and a battery box is built in the mounting base 1 , in which batteries are arranged. The batteries are used to supply power to the electric push rod 2 , and the button switch controls the start and stop of the electric push rod 2 .

[0028] A pair of positioning plates 3 are arranged on the top of the mounting seat 1 . Each of the positioning plates 3 has a groove 301 . A row of springs 4 is arranged in the groove 301 . A resisting plate 5 is fixedly connected to the row of springs 4 . An arc plate 6 is arranged on the surface of the resisting plate 5 .

[0029] A hydrogen leak detector body 7 is placed on the top of the mounting base 1. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a hose 701 is provided on the hydrogen leak detector body 7, and a probe 702 is provided at one end of the hose 701 away from the hydrogen leak detector body 7. The clamping seat 201 has an arc groove, and the probe 702 is clamped in the arc groove.

[0030] When in use, the hydrogen leak detector body 7 is inserted between the two positioning plates 3. The downward movement of the hydrogen leak detector body 7 will squeeze the arc plates 6 on both sides. After being squeezed, the arc plates 6 will compress the springs 4, thereby making the hydrogen leak detector body 7 inserted between the two arc plates 6. Then 703 is inserted into the clamping seat 201, and the switch of the electric push rod 2 is turned on. The electric push rod 2 can move the clamping seat 201 forward, thereby straightening the bent hose 701, so that the probe 702 can be flexibly extended to easily reach narrow or difficult-to-reach hydrogen leakage points, which not only reduces the workload of detection personnel, but also significantly improves the detection efficiency and ensures the accuracy of the detection results.

[0031] Furthermore, a silicone pad is provided in the arc groove, and the probe 702 is wrapped in the arc groove, which can protect the probe 702 during the detection process.

[0032] The surface of the hydrogen leak detector body 7 contacts with a pair of arc-shaped plates 6 , and the surface of the arc-shaped plates 6 is provided with rubber pads, and the rubber pads have anti-slip grooves.

[0033] When disassembling the hydrogen leak detector body 7, the hydrogen leak detector body 7 can be lifted upward to separate the hydrogen leak detector body 7 from the two arc-shaped plates 6, so that the hydrogen leak detector body can be easily installed and disassembled on the mounting base. The user can quickly remove or install the hydrogen leak detector body from the mounting base as needed, thereby adapting to different detection environments and needs and enhancing the practicality of the device.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
