[0026] Please see Figures 1-6 This utility model provides a technical solution:

[0027] A device for testing the hydrogen absorption and dissipation pressure and capacity of a solid hydrogen storage cylinder includes a base 1, a testing device 3 mounted on the top of the base 1, and a dustproof mechanism 2 for dust prevention. The dustproof mechanism 2 includes:

[0028] The housing unit 21 is disposed on the top of the base 1 and includes a rear housing 212. A front housing 217 is fixedly installed on the front side of the rear housing 212. A dustproof net 2110 is fixedly installed on the front side of the front housing 217, and the dustproof net 2110 is fixed to the front side of the front housing 217 by a U-shaped pressure plate 2111.

[0029] The disassembly unit 22 is located above the housing unit 21 and is used to enable quick disassembly between the rear housing 212 and the front housing 217.

[0030] In this embodiment, a fixing seat 211 is fixedly installed on the top of the base 1, a fixing ear 213 is fixedly installed on the outer side of the rear shell 212, and a screw 214 fixes the rear shell 212 to the top of the fixing seat 211. Two inserts 215 are fixedly installed on the front side of the rear shell 212. A raised groove 216 is opened inside the fixing seat 211. A raised block 218 is fixedly installed on the bottom of the front shell 217, and the raised block 218 is adapted to slide inside the raised groove 216. Two insertion holes 2112 are opened on the rear side of the front shell 217, and the inserts 215 are inserted into the insertion holes 2112. Two observation windows 219 are provided on the front side of the front shell 217.

[0031] The raised block 218 slides into the interior of the raised slot 216, causing the front shell 217 to engage with the rear shell 212. At the same time, the insert post 215 is inserted into the interior of the insertion hole 2112 to prevent dust from affecting the device. Furthermore, the dustproof net 2110 installed on the front side of the front shell 217 not only blocks dust but also dissipates heat from the interior of the rear shell 212 and the front shell 217.

[0032] The dustproof net 2110 is pressed onto the front side of the front shell 217 by the U-shaped pressure plate 2111, which makes it easy to replace or clean the dustproof net 2110. The front side of the front shell 217 is provided with two observation windows 219, which makes it easy to observe the inside of the shell unit 21.

[0033] In this embodiment, the disassembly and assembly unit 22 includes a fixing plate 221 fixedly installed on the top of the front shell 217. A fixing post 222 is fixedly installed on one side of the fixing plate 221. A slot 223 is opened on the top of the fixing post 222. A connecting seat 224 is fixedly installed on the top of the connecting seat 224. An insert block 226 is slidably installed through the top of the connecting seat 224. A mounting bracket 225 is fixedly installed on the top of the connecting seat 224. A sliding post 227 is slidably installed through the inside of the mounting bracket 225. The bottom end of the sliding post 227 is fixedly connected to the insert block 226. A baffle 229 is fixedly installed on the surface of the sliding post 227. A spring 228 is sleeved on the surface of the sliding post 227. The fixing post 222 is slidably inserted into the inside of the connecting seat 224, and the insert block 226 is slidably inserted into the inside of the slot 223.

[0034] The slot 223 slides into the interior of the connector 224. At this time, the round head of the slot 223 contacts the inclined surface of the insert 226, pushing the insert 226 upward. Then, the spring 228 pushes the baffle 229 through its own elastic force, causing the insert 226 to move downward, so that the insert 226 is inserted into the interior of the slot 223. This enables quick disassembly between the rear shell 212 and the front shell 217, facilitating maintenance of the devices inside the rear shell 212 and the front shell 217.

[0035] In this embodiment, the testing device 3 includes a hydrogen cylinder 31 fixedly installed on the top of the base 1. The output pipe of the hydrogen cylinder 31 is equipped with a check valve 32, a first solenoid valve 33, a first flow meter 34, a pressure sensor 35, and a first temperature sensor 36. A cooling and heating management system 37 is fixedly installed at one end of the output pipe of the hydrogen cylinder 31. A three-way pipe 38 is fixedly installed on one side of the cooling and heating management system 37. A second solenoid valve 39 is installed on each of the three branches of the three-way pipe 38. An outlet pipe 310 is fixedly installed on one side of the three-way pipe 38, and a second flow meter 311 is fixedly installed on the outlet pipe 310. The cooling and heating management system 37 includes a housing 371, and a water tank 374 is provided inside the housing 371. A second temperature sensor 375 is provided on the left side inside the water tank 374. A solid hydrogen storage device 372 is provided inside the water tank 374. A mold temperature controller 373 is provided at the top of the inner cavity of the housing 371, and two hot and cold water pipes of the mold temperature controller 373 are inserted into the interior of the water tank 374.

[0036] The internal cooling and heating management system 37 includes a solid-state hydrogen storage device 372, a mold temperature controller 373, a second temperature sensor 375, and a PLC control system. The PLC opens the first solenoid valve 33 and controls the mold temperature controller to output cold water. It analyzes data from the first flow meter 34, pressure sensor 35, first temperature sensor 36, and second temperature sensor to determine if the hydrogen charging process is complete. Simultaneously, it calculates the collected flow, pressure, and temperature data and outputs the rated hydrogen storage capacity of the tested solid-state hydrogen storage bottle and the hydrogen absorption rate curve at the corresponding reaction temperature. After hydrogen storage is complete, the first solenoid valve 33 is closed, awaiting the hydrogen release signal. During the hydrogen release process, the PLC controls the mold temperature controller to output hot water and controls three pipes equipped with second solenoid valves 39 to release gas sequentially. While the mold temperature controller outputs hot water, hydrogen is released from the upper pipe. Based on data read by the second flow meter 311, the system determines whether the upper pipe has insufficient gas volume and the flow rate is reduced. If the upper pipe has insufficient gas volume, the middle pipe is switched; if the middle pipe has insufficient gas volume, the lower pipe is switched. The system determines whether the hydrogen release operation has ended based on the pressure sensor 35. After the hydrogen release is completed, the data acquisition system records the hydrogen release capacity of the solid hydrogen storage cylinder group and the hydrogen release rate curve at the corresponding reaction temperature. Then, the mold temperature controller and the three second solenoid valves 39 are turned off.

[0037] Furthermore, the PLC control system is connected to the host computer software. Using a PLC control system in conjunction with the host computer software ensures high reliability and stability, enabling long-term stable operation in harsh industrial environments. For small-scale testing devices, the development and debugging costs and difficulties are significantly reduced, and it offers good maintainability and scalability. Simultaneously, the host computer software and PLC have high integration and compatibility, ensuring seamless communication between them. This allows for the acquisition, processing, and storage of real-time and historical data, meeting various complex data processing needs. All content not described in detail in this specification is prior art known to those skilled in the art.

[0038] During operation, firstly, the raised block 218 slides into the interior of the raised slot 216, causing the front shell 217 to engage with the rear shell 212. At the same time, the insert post 215 is inserted into the interior of the insertion hole 2112. Then, the slot 223 slides into the interior of the connector 224. At this time, the round head of the slot 223 contacts the inclined surface of the insert block 226, pushing the insert block 226 upward. Then, the spring 228 pushes the baffle 229 through its own elastic force, causing the insert block 226 to move downward, so that the insert block 226 is inserted into the interior of the slot 223.
