[0038] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0039] The utility model provides a fuel cell hydrogen temperature and humidity detection device. By arranging a movable component and a protective component, when the detection device is completely exposed to the outside, the vertical plate and the protective plate can protect the front of the device to prevent the device from being accidentally impacted.

[0040] Figures 1-4 The figure shows the overall structure of a fuel cell hydrogen temperature and humidity detection device according to the present invention. Figures 1-4 The main body of a fuel cell hydrogen temperature and humidity detection device in this embodiment includes: a main body component 100, a moving component 200, and a protective component 300.

[0041] The main assembly 100 is the device itself. Specifically, the main assembly 100 includes a body 110 ; the main assembly 100 also includes an air inlet 120 , a temperature sensor 130 , and a display screen 140 ;

[0042] The air inlet 120 is fixed on the upper side of the body 110 , the thermometer 130 is fixed on the one side of the body 110 , and the display screen 140 is fixed on the lower side of the other side of the body 110 .

[0043] In specific use, the air inlet 120 is used for inhaling air, and the mobile assembly 200 is installed and used based on the main assembly 100. The air inlet 120 is used for detecting hydrogen entering the device. The air inlet 120 is fixed to the upper right side of the front of the main body 110. The thermometer 130 is used for sensing temperature. The thermometer 130 is fixed to the right side of the front of the main body 110. The display screen 140 is used for displaying data. The display screen 140 is fixed to the lower left side of the main body 110.

[0044] The moving assembly 200 is used in conjunction with the protective assembly 300. Specifically, the moving assembly 200 includes a slide groove 210 provided on the side wall of the body 110, a slider 220 inserted into the slide groove 210, a connecting block 230 connected to the slider 220, and a connecting plate 240 fitted with the connecting block 230; the connecting block 230 is located on the outer side of the slider 220, the slider 220 moves vertically along the slide groove 210, and the slider 220 drives the connecting block 230 and the connecting plate 240 to move vertically; the connecting plate 240 is movably connected to the connecting block 230 at the contact point There is a movable shaft 2410, and a group of springs 250 are fixedly connected to one side of the connecting plate 240; the protective assembly 300 includes a mounting plate 310 fixed between the outer ends of the springs 250, a vertical plate 320 fixed to the inner side of the mounting plate 310, a protective plate 330 fixed to the side of the vertical plate 320, protective holes 340 opened on both sides of the protective plate 330, mounting holes 350 opened on the sides of the mounting plate 310 and the vertical plate 320, and a mounting rod 360 passing through the mounting hole 350; wherein the mounting rod 360 is progressively threaded along the internal thread of the mounting hole 350;

[0045] When in use, hydrogen enters the inner side of the protective plate 330 through the protective hole 340, so that the device can detect hydrogen. When impacted, the left and right mounting plates 310 move backwards through the springs 250 on the rear side. At the same time, the springs 250 buffer the impact force, so that the protective plate 330 moves backwards due to the thrust, protecting the front of the body 110. When the staff operates the device, they push the protective plate 330 upwards by hand, and the protective plate 330 moves upwards through the sliders 220 on both sides of the body 110. When the protective plate 330 moves to the top, they rotate the protective plate 330 by hand. The protective plate 330 is rotated upward through the connecting plate 240 and the movable shaft 2410, so that the protective plate 330 is rotated to the top of the main body 110, which makes it easier for the staff to operate the device; when removing the vertical plate 320 and the protective plate 330, the mounting rod 360 is rotated by hand so that the mounting rod 360 leaves the mounting hole 350, thereby realizing the separation of the vertical plate 320 and the mounting plate 310. The mounting holes 350 are opened on the left and right sides of the mounting plate 310 and the left and right sides of the vertical plate 320. The mounting holes 350 are opened to facilitate the insertion of the mounting rod 360 and also to facilitate the loading and unloading of the vertical plate 320.

[0046] Furthermore, the inner side of the vertical plate 320 is in contact with the body 110 , and the protective holes 340 are evenly distributed on both sides of the vertical plate 320 . The protective holes 340 are used to allow the entry of outside air or other gases, making it easier for the device to detect hydrogen.

[0047] Furthermore, since the protective plate 330 is relatively large and is only connected to the connecting block 230 on the outside of the slider 220, the stability of the protective plate 330 is relatively poor. Figure 1 、 Figure 5-Figure 6 , in order to solve this problem, a limit assembly 400 is set, specifically, it also includes a limit assembly 400, the limit assembly 400 includes a connecting rod 410 and a group of limit holes 420; the connecting rod 410 is fixed on both sides of the body 110, the limit holes 420 are opened on both sides of the connecting rod 410, the connecting rod 410 is fixed on the left and right sides of the body 110, the connecting rod 410 is used to open the limit holes 420, the limit holes 420 are opened on the front and rear sides of the connecting rod 410, the limit holes 420 are used to connect other components, and one end edge of the outer side of the vertical plate 320 is fixedly connected A group of square plates 430, each of which is penetrated by a cross bar 440, are fixed at the rear edge of the outer side of the vertical plate 320, the square plates 430 are used to place the cross bar 440, and the cross bar 440 is used to place other components. A moving rod 450 is sleeved inside the cross bar 440, and the outer end of the moving rod 450 is threadedly connected to the limiting hole 420. The moving rod 450 can move inside the cross bar 440, and the moving rod 450 can also rotate inside the cross bar 440. The moving rod 450 is threadedly connected to the limiting hole 420 to facilitate the connection of the moving rod 450.

[0048] During specific use, the moving rod 450 is rotated by hand, and the rear end of the moving rod 450 is gradually separated from the limiting hole 420, and the front end of the moving rod 450 rotates and moves inside the cross bar 440. When the rear end of the moving rod 450 completely leaves the limiting hole 420, the protective plate 330 can be pushed upward, and the protective plate 330 moves upward through the moving components 200 on both sides.

[0049] For further information, please refer to Figure 7-Figure 9, due to the opening of the protective hole 340, the frame support capacity around the protective hole 340 is weak, and once it is squeezed, it will deform. At this time, in order to ensure the normal use of the protective plate 330, the entire protective plate 330 needs to be replaced. To this end, a replacement component 500 is provided to form a movable and replaceable structural design at the position of the protective hole 340. In this way, the position of the deformed protective hole 340 can be replaced separately without replacing the entire part. Specifically, the replacement component includes a rectangular opening 510 opened on the surface of the protective plate 330, a rectangular opening 510 opened on the surface of the protective plate 330, and a rectangular opening 510 opened on the surface of the protective plate 330. The rectangular long slot 520 in the rectangular opening 510, the horizontal plate 530 disposed below the protective plate 330, the bottom plate 540 fixed to the bottom surface of the horizontal plate 530, the threaded hole 550 provided on the surface of the bottom plate 540, the first rectangular frame 560 fitted with the rectangular long slot 520, the first protective long hole 570 provided on the surface of the first rectangular frame 560, the second rectangular frame 580 disposed above the first rectangular frame 560, the second protective long hole 590 provided on the surface of the first rectangular frame 560, and the long spring 5100 fixed to the surface of the horizontal plate 530;

[0050] During actual use, the horizontal plate 530 is inserted into the rectangular long slot 520, and the bottom plate 540 is attached to the bottom surface of the protective plate 330. At this time, a long threaded rod is used to pass through the threaded hole 550 for locking. The long spring 5100 can press several distributed first rectangular frames 560. In this way, when replacement is needed, the user removes the bottom plate 540, and then removes the distributed first rectangular frames 560 through the rectangular long slot 520. In this way, the deformed rectangular frame can be replaced separately without replacing the entire protective plate 330.

[0051] For further information, please refer to Figure 7-Figure 9 The vertically distributed first rectangular frame 560 and the second rectangular frame 580 are limited by a positioning assembly 600 to prevent shaking. Specifically, the positioning assembly 600 includes a first limiting post 610 fixed to the bottom surface of the first rectangular frame 560, a circular hole 620 opened at the top of the first rectangular frame 560, and a second limiting post 630 fixed to the bottom surface of the second rectangular frame 580.

[0052] When the first rectangular frame 560 and the second rectangular frame 580 are stacked, the circular holes 620 and the second limiting pillars 630 fit together, so that they can be positioned and prevent the rectangular frames from shaking.

[0053] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
