The top of the inner wall of the protective cabinet 5 near both sides is installed with telescopic rods 23 through support blocks 22. The telescopic ends of the telescopic rods 23 are fixedly connected with connecting blocks 29. Activity openings 28 are opened at the back of the protective cabinet 5 near both sides. The top of the inner wall of the protective cabinet 5 near both sides is installed with slide rails 24. The bottoms of the slide rails 24 are slidably connected with partition plates 14 through slide bars 25. Two injection pipes 17 are installed on the top of the inner wall of the protective cabinet 5 at the front position through a sliding component 8.

The front, back, and bottom of the partition plate 14 are respectively in contact with the detection table 1, the cabinet door 7, and the back of the protective cabinet 5. The backward movement of the partition plate 14 is to facilitate the adjustment of the position of the placement plate 12 on the detection table 1 so that it is located in the corresponding temperature zone. After the partition plate 14 is opened, the two temperature zones will be briefly combined. Since the combination time is short, it will not have a great impact on temperature control.

[0040] The working principle of the hydrogen fuel cell stack detection device provided by the present utility model is as follows:

[0041] First, install a high and low temperature machine 6 that can achieve low, medium, and high temperature zones on the detection table 1 through the protective cabinet 5. Then, install two partition plates 14 inside the protective cabinet 5 through two groups of slide rails 24 and slide bars 25, dividing its interior into three different zones, so that the high and low temperature machine 6 can control different temperatures in the three different zones. The two partition plates 14 are pushed backward by the telescopic rod 23 and move out from the movable opening 28, so that the hydrogen fuel cell stack 16 on the placement plate 12 can adjust its position left and right on the detection table 1, enabling it to be detected at different temperatures. The placement plate 12 is driven by the driving component 4 to drive the threaded rod 19 to rotate, which can drive the placement plate 12 on the internally threaded frame 21 to adjust its position. The internally threaded frame 21 passes through two slide rods 20, which can increase the stability of the movement of the internally threaded frame 21. During actual use, first install the hydrogen fuel cell stack 16 on the placement plate 12, then connect the two injection pipes 17 to the hydrogen inlet and air inlet of the hydrogen fuel cell stack 16 respectively. Then start the high and low temperature machine 6 to make the three zones inside the protective cabinet 5 reach the set temperature. Then start the driving component 4 to move the placement plate 12 to the first temperature test zone. Before the placement plate 12 moves, the telescopic rod 23 will push the corresponding partition plate 14 backward, so that the placement plate 12 can move smoothly between the two zones inside the protective cabinet 5. After the placement plate 12 moves into place, the telescopic rod 23 drives the partition plate 14 to reset. During the movement of the placement plate 12, the injection pipe 17 is subjected to traction and will move synchronously to the detection zone through the sliding component 8. Then, only need to start the air supply component 10 and the hydrogen supply component 9 to test the performance or safety of the hydrogen fuel cell stack 16. During the test, the placement plate 12 can be moved and detected in the three zones inside the protective cabinet 5 according to requirements.

[0042] Compared with the related art, the hydrogen fuel cell stack detection device provided by the present utility model has the following beneficial effects:

[0043] In order to increase the comprehensiveness of data during the detection of a hydrogen fuel cell stack, first, a high and low temperature machine 6 capable of achieving bottom, middle, and high temperature zoning is installed on the detection bench 1 through the protective cabinet 5. Then, two partition plates 14 are installed inside the protective cabinet 5 through two groups of slide rails 24 and slide bars 25, dividing its interior into three different areas, so that the high and low temperature machine 6 can control different temperatures in the three different areas. The two partition plates 14 are pushed backward by the telescopic rod 23 and move out from the movable opening 28, enabling the hydrogen fuel cell stack 16 on the placement plate 12 to be adjusted left and right on the detection bench 1, allowing it to be detected at different temperatures. The placement plate 12 is driven by the driving assembly 4 to drive the threaded rod 19 to rotate, which can drive the placement plate 12 on the internally threaded frame 21 to adjust its position. The internally threaded frame 21 passes through two sliding rods 20, which can increase the stability of the movement of the internally threaded frame 21. With this structure, the hydrogen fuel cell stack 16 can be detected at different temperatures, and the three areas separated by the three partition plates 14 inside the protective cabinet 5 can maintain or quickly reach the set temperature, improving the detection efficiency while obtaining more comprehensive detection data.

[0044] Second Embodiment

Based on the hydrogen fuel cell stack detection device provided in the first embodiment of the present application, the second embodiment of the present application proposes another hydrogen fuel cell stack detection device. The second embodiment is merely a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0046] Specifically, the difference of the hydrogen fuel cell stack detection device provided in the second embodiment of the present application is that a limiting plate 34 is fixedly connected to the position on the top of the placement plate 12 at the back, and a support plate 30 is fixedly connected to the position on the top of the placement plate 12 at the front;

[0047] Threaded holes and two round holes are respectively formed on the support plate 30, which are convenient for threaded connection with the adjusting screw 31 and for the stabilizing rod 32 to pass through.

[0048] The adjusting screw 31 is threadedly connected to the front of the support plate 30. One end of the back of the adjusting screw 31 is rotatably connected to a clamping plate 36, and a contact pad 35 is installed on the back of the clamping plate 36;

[0049] The contact pad 35 is also installed on the front surface of the limit plate 34. The hydrogen fuel cell stack 16 is located between the clamping plate 36 and the limit plate 34. The contact pad 35 can reduce wear and play a buffering role. The adjusting screw 31 threadedly penetrates through the support plate 30.

[0050] On the front surface of the clamping plate 36 near both sides, fixing pieces 33 are fixedly connected. On the front surfaces of the fixing pieces 33, stabilizing rods 32 are fixedly connected.

[0051] The stabilizing rod 32 penetrates through the support plate 30 to increase the stability of the forward and backward movement of the clamping plate 36.

[0052] Compared with the related art, the hydrogen fuel cell stack detection device provided by the present utility model has the following beneficial effects:

[0053] In order to facilitate the quick disassembly and assembly of the hydrogen fuel cell stack 16 on the placement plate 12 to improve the detection efficiency, a limit plate 34 with a contact pad 35 is installed on the top of the placement plate 12 at the back, and at the same time, a support plate 30 is installed at the front position on the top of the placement plate 12. An adjusting screw 31 is installed on the front surface of the support plate 30. Then, only need to install the clamping plate 36 at one end of the adjusting screw 31 through a rotatable buckle, so that the clamping plate 36 and the limit plate 34 are adjacent to each other. In order to increase the stability of the movement of the clamping plate 36, a stabilizing rod 32 is installed on both sides of the front surface of the clamping plate 36 through the fixing pieces 33, and the stabilizing rod 32 is made to penetrate through the support plate 30. In actual use, first place the hydrogen fuel cell stack 16 on the placement plate 12 and make its back surface contact the front surface of the limit plate 34. Then, rotate the adjusting screw 31 to adjust the distance between the clamping plate 36 and the limit plate 34. When the front surface of the clamping plate 36 contacts the hydrogen fuel cell stack 16, it clamps the hydrogen fuel cell stack 16 between the limit plate 34 and the clamping plate 36. When it is necessary to disassemble, only need to rotate the adjusting screw 31 in the reverse direction to make the clamping plate 36 away from the limit plate 34, and the restriction on the hydrogen fuel cell stack 16 can be released. Through this design, the quick disassembly and assembly of the hydrogen fuel cell stack 16 can be realized, which is beneficial to improving the detection efficiency of the hydrogen fuel cell stack 16.
