Abstract
Description
Technical Field
[0001] The present invention relates to the field related to hydrogen detection technology, and in particular to a hydrogen detection device for hydrogen fuel vehicles. Background Art
[0002] A hydrogen fuel cell vehicle is a vehicle that uses hydrogen as its primary energy source for propulsion. While conventional internal combustion engines are typically fueled by diesel or gasoline, hydrogen vehicles use gaseous hydrogen instead. Fuel cells and electric motors replace conventional engines. The principle of a hydrogen fuel cell is that hydrogen is fed into the fuel cell. The electrons in the hydrogen atoms are blocked by a proton exchange membrane and conducted from the negative electrode to the positive electrode through an external circuit, becoming electricity to drive the motor. However, protons can pass through the proton exchange membrane and combine with oxygen to form pure water mist, which is then discharged. To ensure stable operation, hydrogen fuel cell vehicles typically install hydrogen gas detectors near their fuel cells. However, existing hydrogen gas detectors are typically installed with bolts and perform detection via a detection structure. However, these devices are unable to adjust the angle of detection, severely impacting detection quality and reducing the overall device's practicality. Therefore, based on the above problems, the present invention provides a hydrogen detection device for hydrogen fuel vehicles. Summary of the Invention

[0015] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0016] Example 1 To solve the technical problems in the background technology, a hydrogen detection device for a hydrogen fuel vehicle is provided as follows: Combine Figure 1-4 As shown, the present invention provides a hydrogen gas detection device for hydrogen fuel cell vehicles, comprising a base plate 1, with bases 2 fixedly mounted at the four corners of the bottom surface of the base plate 1. The provision of the bases 2 increases the practicality of the overall device. Two T-shaped connecting plates 6 are disposed above the base plate 1, and the two T-shaped connecting plates 6 are connected to the base plate 1 via a mating adjustment member 7. Furthermore, a plurality of guide members are disposed between each T-shaped connecting plate 6 and the base plate 1. A mounting tube 8 is fixed between the two T-shaped connecting plates 6. A polygonal connecting plate 15 is provided above the mounting tube 8. A T-shaped mating rod 10 is slidably provided on the polygonal connecting plate 15. A mating spring 9 is provided between each T-shaped mating rod 10 and the polygonal connecting plate 15. Each mating spring 9 is sleeved on the corresponding T-shaped mating rod 10. A detection sensor 13 is installed on the top of each T-shaped mating rod 10. A detection head 12 is installed on the top of each detection sensor 13. The detection head 12 is provided with a number of air inlet holes. A mating round head 11 is fixed on the bottom end of each T-shaped mating rod 10, and a detection adjustment member 14 is provided between the polygonal connecting plate 15 and the mounting tube 8. An L-shaped connecting plate 5 is fixed on the opposite end of the two T-shaped connecting plates 6. Each L-shaped connecting plate 5 is fixed to the polygonal connecting plate 15.
[0017] The cooperating adjustment component 7 includes two U-shaped fixing blocks 75 and two U-shaped connecting blocks 71. Each U-shaped fixing block 75 is fixed to the top surface of the base plate 1. A convex groove is provided on each U-shaped fixing block 75. A sliding plate 77 is slidably provided in each convex groove. A rack plate 76 is fixed on the top surface of each sliding plate 77. Each rack plate 76 is slidably provided in the corresponding convex groove, and a double connecting plate 73 is rotatably provided in each U-shaped fixing block 75. A meshing gear 74 is fixed in each double connecting plate 73. Each meshing gear 74 is meshed with the corresponding rack plate 76. Each U-shaped connecting block 71 is fixed to the corresponding T-shaped connecting plate 6. A hinged connecting plate 72 is movably hinged between each U-shaped connecting block 71 and the corresponding double connecting plate 73, and a synchronous adjustment member is provided between the two sliding plates 77 and the base plate 1.
[0018] The synchronous adjustment component includes a first motor 791, which is fixed on the base plate 1. An adjustment gear 79 is fixed on the power output end of the first motor 791. L-shaped rack plates 78 are meshed on both sides of the adjustment gear 79, and each L-shaped rack plate 78 is fixed to the corresponding sliding plate 77.
[0019] The guide member includes a guide cylinder 4, which is fixed to the top surface of the base plate 1. A guide rod 3 slides inside the guide cylinder 4, and the top end of the guide rod 3 is fixedly connected to the T-shaped connecting plate 6. The guide member (guide rod 3 and guide cylinder 4) limits the deviation of the T-shaped connecting plate 6 during height adjustment, ensuring smooth lifting.
[0020] Working principle: The function of the cooperation adjustment member 7 is to realize the synchronous lifting and lowering of multiple detection heads 12 through mechanical linkage to meet the detection requirements of different heights. The specific process is as follows: The synchronous adjustment member is started: the first motor 791 (the power source of the synchronous adjustment member) is started, and its power output end drives the adjustment gear 79 to rotate. Since the adjustment gear 79 is meshed with L-shaped rack plates 78 on both sides, and the L-shaped rack plates 78 are fixedly connected to the sliding plate 77, the rotation of the adjustment gear 79 drives the L-shaped rack plates 78 on both sides to slide synchronously in opposite directions (one side to the left and the other side to the right); The rack plate 76 is linked to the meshing gear 74: the L-shaped rack plate 78 drives the sliding plate 77 to slide in the convex groove of the U-shaped fixed block 75, and the rack plate 76 on the top surface of the sliding plate 77 slides along with it. The rack plate 76 meshes with the meshing gear 74 (fixed on the double-connected plate 73) in the U-shaped fixed block 75. Therefore, the sliding of the rack plate 76 drives the meshing gear 74 to rotate, thereby driving the double-connected plate 73 to rotate synchronously; T-shaped connecting plate 6 lifting: The double connecting plate 73 is hinged to the U-shaped connecting block 71 (fixed on the T-shaped connecting plate 6) through the hinged connecting plate 72. The rotation of the double connecting plate 73 will push the U-shaped connecting block 71 and the T-shaped connecting plate 6 to rise and fall synchronously through the hinged connecting plate 72. At this time, the guide member (the guide rod 3 slides along the guide cylinder 4) ensures that the T-shaped connecting plate 6 does not deviate during the lifting process, thereby improving stability; The detection heads 12 rise and fall synchronously: the T-shaped connecting plate 6 rises and falls, driving the L-shaped connecting plate 5, polygonal connecting plate 15 and T-shaped matching rod 10 (including detection sensor 13 and detection head 12) fixed thereto to rise and fall synchronously, ultimately realizing the height adjustment of multiple detection heads 12.
[0021] Example 2 like Figure 1-4 As shown, based on the above embodiment, this embodiment further provides the following content: The detection and adjustment component 14 includes a matching circular plate 145 and a second motor 141. A matching ball 144 is fixedly provided on the matching circular plate 145. The matching ball 144 is rotatably arranged in the mounting tube 8. The second motor 141 is fixedly provided on the polygonal connecting plate 15. A folding adjustment plate 142 is fixedly provided on the power output end of the second motor 141. A mounting shaft 143 is installed on the folding adjustment plate 142. The bottom end of the mounting shaft 143 is fixedly connected to the matching ball 144. Each matching round head 11 is in contact with the matching circular plate 145.
[0022] In specific use, based on the first embodiment, when it is necessary to further increase the practicality of the overall device: The function of the detection adjustment member 14 is to achieve synchronous angle adjustment of multiple detection heads 12 through mechanical linkage to expand the detection range. The specific process is as follows: The detection adjustment member 14 is started: the second motor 141 is started, and its power output end drives the folding adjustment plate 142 to rotate. The folding adjustment plate 142 drives the matching ball 144 to rotate universally in the mounting tube 8 through the mounting shaft 143 (the matching ball 144 and the mounting tube 8 are rotationally matched to achieve multi-angle deflection); Tilt linkage of the mating circular plate 144: The mating ball 144 is fixedly connected to the mating circular plate 145, so the rotation of the mating ball 144 will drive the mating circular plate 145 to tilt and rotate (the angle changes with the deflection of the mating ball); Adaptive adjustment of the angle of the detection head 12: the mating circular plate 145 contacts the mating round head 11 at the bottom end of the T-shaped mating rod 10, and a mating spring 9 (sleeved on the T-shaped mating rod 10) is provided between the T-shaped mating rod 10 and the polygonal connecting plate 15. When the mating circle 145 is tilted, the mating round head 11 always fits with the surface of the mating circular plate 145 under the elastic force of the mating spring 9, thereby driving the T-shaped mating rod 10 to slide along the polygonal connecting plate 15 and deflect the angle. Finally, the detection sensor 13 and the detection head 12 at the top of the T-shaped mating rod 10 deflect with the angle, thereby realizing synchronous angle adjustment of multiple detection heads 12.
