Description

Technical Field

[0001] The present invention relates to the technical field of fuel cell safety detection, and in particular to a fuel cell detection device. Background Art

[0002] As the global energy structure transitions to a low-carbon one, fuel cells, as an efficient and clean energy conversion device, have been widely used in new energy vehicles, large ships, distributed power generation, and other fields. However, fuel cells usually contain flammable and explosive substances such as hydrogen, and the working environment involves complex working conditions such as temperature and pressure. Once structural damage, seal failure, or thermal runaway occurs, it may cause safety accidents such as leakage, combustion, or even explosion. Therefore, comprehensive and accurate testing of the safety of fuel cells has become an important link to ensure their industrial application.

[0003] Among them, large ships may encounter extreme working conditions such as collisions with underwater obstacles (such as reefs and floating objects), cargo shifting and collision in the cargo hold, and hull vibration fatigue during navigation. In the long term, these conditions may cause the fuel cell pipeline interface to tear, and puncture may directly damage the core structure of the fuel cell, causing hydrogen leakage. If an electric spark is encountered, the cabin may explode. The current detection device is not only cumbersome to operate and has low detection efficiency, but may also affect the detection accuracy due to the transfer process. After the puncture test, the battery residue is difficult to clean, and the accumulation of residue can easily affect the accuracy of subsequent detection, and manual cleaning poses a safety hazard. In addition, the existing detection device has a low degree of automation and relies more on manual operation, which not only increases labor costs, but also may cause detection errors due to human factors.

[0025] In this embodiment, a puncture detection mechanism 3 for puncturing the battery and detecting heat is provided on the inner wall of the first shell 21.

[0028] Specifically, the angle sensor 392 adjusts the puncture angle, and the second electric telescopic rod 39 pushes the puncture needle 393 to puncture the battery at a set speed. At this time, the cover plate 397 moves following the movement of the puncture needle 393.

[0029] In this embodiment, a plurality of first elastic components 396 are provided on one side wall of the third connecting plate 394, and a second rotating plate 3991 is provided on the other end of each of the first elastic components 396.

At the moment of puncture, the temperature sensor 399 on the covering plate 397 monitors the temperature changes on the battery surface in real time and records the thermal runaway data. If the temperature rises abnormally, the dry powder fire extinguisher 38 transports dry powder to the inside of the covering plate 397 through the telescopic transmission tube 395, and then sprays it through multiple nozzles 398, ready to extinguish the fire at any time.

[0031] In this embodiment, a side wall of the first shell 21 is provided with a leakage detection mechanism 4 for performing gas detection on the punctured part of the battery. The leakage detection mechanism 4 includes two second electric sliders 43 slidably connected to the inner side walls of the second electric slides 27. The corresponding end side walls of the two second electric sliders 43 are fixedly connected to the same second guide plate 44. A fourth electric slide 45 is provided on the top side wall of the second guide plate 44. The fourth electric slide 45 is slidably connected to the inner side wall of the fourth electric slide 45.

An air pump 42 is provided on the top side wall of the nitrogen tank 41. An air supply pipe 492 is provided at the output end of the air pump 42. The air supply pipe 492 passes through the first shell 21 and is fixedly connected to the sleeve 49.

[0034] Specifically, the air pump 42 is started to extract nitrogen from the nitrogen tank 41 and inject it into the sleeve 49 through the air pipe 492 to dilute the leaked hydrogen and prevent it from accumulating.

[0035] In this embodiment, the vibration mechanism 5 includes two fixed frames 51 fixedly connected to the top side walls of the support frame 1, and the corresponding ends of the two fixed frames 51 are each provided with a fifth electric slide 52, and the inner walls of the two fifth electric slides 52 are both slidably connected with a fifth electric slider 53, and the corresponding ends of the two fifth electric sliders 53 are fixedly connected to the same second shell 54, and a temperature adjustment component 56 is provided at the top of the inner wall of the second shell 54, and a fourth electric telescopic rod 57 is provided at the top of the inner wall of the second shell 54, and a vibration plate 58 is provided at the telescopic end of the fourth electric telescopic rod 57, and a second sealing strip 55 is provided on the bottom side wall of the second shell 54.

[0036] Specifically, the fifth electric slider 53 slides downward in the fifth electric slide groove 52, causing the second shell 54 to move downward, so that the second sealing strip 55 is inserted into the second sealing groove 14 to form a closed test space. The temperature debugging component 56 adjusts the temperature in the chamber to the target value, so that the battery body 6 can be punctured at different temperatures. The fourth electric telescopic rod 57 pushes the vibration plate 58 to contact the battery surface, applying small vibrations at a certain frequency to simulate the bumpy driving of the ship for a certain period of time to test the structural stability and performance changes of the battery under vibration conditions.

[0037] In this embodiment, four positioning columns 594 are provided on the top side wall of the support frame 1, and the outer walls of the four positioning columns 594 are provided with holes in a circular array, and the inner walls corresponding to the holes are fixedly connected with the sixth electric telescopic rod 595, and the telescopic ends of multiple sixth electric telescopic rods 595 are fixedly connected with the positioning plate 596, and the top side wall of the support frame 1 is provided with four second slots 59, and the bottom ends of the inner walls of the four second slots 59 are fixedly connected with the fifth electric telescopic rod 591, and the telescopic ends of the four fifth electric telescopic rods 591 are provided with a buffer plate 592, and the bottom ends of the inner walls of the four second slots 59 are fixedly connected with the second elastic component 593, and the other end of the second elastic component 593 is fixedly connected to the bottom end of the buffer plate 592.

[0038] Specifically, multiple fifth electric telescopic rods 591 are extended, driving the buffer plate 592 to rise, so that the top of the buffer plate 592 is flush with the bottom of the positioning plate 596, and the fixed block 61 is placed on the outside of the four positioning columns 594, and then multiple sixth electric telescopic rods 595 are extended, pushing the positioning plate 596 to move toward the inner wall of the fixed block 61 until the positioning plate 596 contacts the inner wall of the fixed block 61 and stops.

[0039] It should be noted that the present invention is a fuel cell detection device. The user places the fuel cell body 6 on the top of the support frame 1, and multiple fifth electric telescopic rods 591 are extended to drive the buffer plate 592 to rise, so that the top of the buffer plate 592 is flush with the bottom of the positioning plate 596, and the fixing block 61 is respectively placed on the outside of the four positioning columns 594. Then, multiple sixth electric telescopic rods 595 are extended to push the positioning plate 596 to move toward the inner wall of the fixing block 61 until the positioning plate 596 contacts the inner wall of the fixing block 61 and stops, thereby ensuring the test process. The middle position is stable and is initially positioned by four positioning columns 594. At this time, the second shell 54 is located directly above the battery. Subsequently, the fifth electric slider 53 slides downward in the fifth electric slide groove 52, causing the second shell 54 to move downward, so that the second sealing strip 55 is inserted into the second sealing groove 14 to form a closed test space. Then the fifth electric slider 53 stops moving. At the same time, multiple first electric telescopic rods 25 contract, driving the first shell 21 to rise, so that the first sealing strip 23 is inserted into the first sealing groove 12 at the bottom end of the support frame 1, thereby forming a relatively closed test environment.

[0040] The first electric slider 31 slides in the first electric slide 22, driving the first guide plate 32 to move above the puncture position, and the third electric slider 34 slides in the third electric slide 33 to further fine-tune the puncture point position, and the third motor 36 drives the first rotating block 37 to rotate to adjust the puncture angle. The angle sensor 392 feeds back the angle data in real time to align the puncture needle 393 with the target area of ​​the battery. The first rotating block 37 is driven to rotate by the third motor 36, and the puncture angle is adjusted in combination with the angle sensor 392. The second electric telescopic rod 39 pushes the puncture needle 393 to puncture the battery at a set speed. At this time, the cover plate 397 moves following the movement of the puncture needle 393, and through the action of multiple first elastic components 396 and the second rotating plate 39 91 is rotatably connected to the second rotating block 3992, so that the temperature sensor 399 can tightly contact the bottom end of the battery body 6. At the moment of puncture, the temperature sensor 399 on the cover plate 397 monitors the temperature change of the battery surface in real time and records the thermal runaway data. If the temperature rises abnormally, the dry powder fire extinguisher 38 transports dry powder to the inside of the cover plate 397 through the telescopic transmission tube 395, and then sprays it through multiple nozzles 398, ready to extinguish the fire at any time. After the puncture is completed, the second electric telescopic rod 39 pulls the puncture needle 393 away from the bottom of the battery, and then the second electric slider 43 slides in the second electric slide 27, driving the second guide plate 44 to move to just below the puncture point, and the fourth electric slider 46 slides in the fourth electric slide 45, so that the sleeve 49 is located at the puncture point. The point is just below the puncture point. Subsequently, the third electric telescopic rod 48 is extended to make the top of the sleeve 49 contact with the bottom of the battery body 6, so that the sleeve 49 covers the entire puncture site. At this time, the leaked hydrogen is detected in real time by the gas sensor 491 to judge the battery sealing. If hydrogen leakage is detected, the air pump 42 is started to extract nitrogen from the nitrogen tank 41 and inject it into the sleeve 49 through the gas pipe 492 to dilute the leaked hydrogen and prevent it from gathering. The valve body 26 is opened to avoid excessive gas pressure in the first shell 21. If the temperature does not change significantly, the first electric slider 31 slides in the first electric slide groove 22 and the third electric slider 34 slides in the third electric slide groove 33 to adjust the puncture point position again and perform the puncture on different target areas at the bottom of the battery body 6 again. Puncture, and the first rotating block 37 can be driven to rotate by the third motor 36, and the puncture angle can be adjusted in combination with the angle sensor 392, so that the puncture needle 393 can simulate different directions of impact on the bottom of the battery body 6. If there is no hydrogen leakage at each puncture, the second electric slider 43 slides in the second electric slide 27, and the fourth electric slider 46 slides in the fourth electric slide 45, so that the sleeve 49 is again located directly below the next puncture point, and the sleeve 49 covers the entire puncture site, and the test is performed again. During the test, the temperature debugging component 56 starts to work and adjusts the temperature in the chamber to the target value, so that the battery body 6 can be punctured at different temperatures. The fourth electric telescopic rod 57 pushes the vibration plate 58 to contact the battery surface.A small vibration is applied at a certain frequency to simulate the bumpy movement of a ship for a certain period of time to test the structural stability and performance changes of the battery under vibration conditions. At the same time, the multiple fifth electric telescopic rods 591 begin to contract, and the multiple second elastic components 593 provide cushioning.

[0041] After the detection is completed, the puncture detection mechanism 3 and the leakage detection mechanism 4 are reset, and the two first motors 28 respectively drive the two inclined plates 29 to rotate and open, so that the two inclined plates 29 are rotated to a vertical state, and the residue dropped after the battery is punctured falls to the bottom of the first shell 21. Then the second motor 291 drives the bidirectional threaded rod 292 to rotate, driving the cleaning plate 293 to move back and forth, pushing the residue to the opening position where the inclined plate 29 leaks out after opening, and completing the cleaning.
