Referring to fig. 1, the present embodiment provides a hydrogen leakage prevention device 10. The hydrogen leakage preventing device 10 is used to prevent hydrogen leakage at the sleeve 120 connecting the ends of two hydrogen pipes 110. The hydrogen leakage prevention apparatus 10 includes a protective casing 200, a first storage tank 230, and a second storage tank 240. The protective housing 200 encloses a first chamber 210 and a second chamber 220. The two ends of the sleeve 120 are located in the first and second chambers 210 and 220, respectively.

The first medium 232 and the second medium 242 react and solidify upon contact to seal the two ends of the casing 120.
The protective case 200 may be made of a polyester material or a stainless steel metal material. The first chamber 210 and the second chamber 220 may be separated by a partition. The middle of the clapboard can be provided with a through hole. The hydrogen pipe 110 may pass through the through-hole. The sleeve 120 may be an internally threaded tube. The two hydrogen pipes 110 may be connected by the sleeve 120. The first storage tank 230 and the second storage tank 240 may have a cubic, spherical, or the like structure. The first medium 232 may be natural glue. The second medium 242 may be a hardening agent. The first medium 232 and the second medium 242 solidify rapidly upon contact. It will be appreciated that the location of a conduit connection hydrogen leak is generally the junction of the sleeve 120 and the hydrogen conduit 110.

The controller 270 is configured to control the operation state of the fifth switching device 291 according to the hydrogen concentrations sensed by the first hydrogen sensor 262 and the second hydrogen sensor 264. The accumulator 250 may supply gas to the first storage tank 230 and the second storage tank 240 through the fifth output pipe 289 and the sixth output pipe 292, respectively, so as to push the first medium 232 and the second medium 242 to be output from the first storage tank 230 and the second storage tank 240.

In one embodiment, the first chamber 210 and the second chamber 220 are respectively provided with a vent 310. That is, the first chamber 210 is provided with the vent 310, and the second chamber 220 is also provided with the vent 310. The air pressure in the first chamber 210 and the second chamber 220 can be kept the same as the ambient air pressure through the vent 310, thereby facilitating the first medium 232 and the second medium 242 to enter the first chamber 210 and the second chamber 220.
Referring to fig. 3, in one embodiment, the hydrogen leakage prevention apparatus 10 further includes two barrier rings 320. The blocking ring 320 is disposed in the first chamber 210 and the second chamber 220, respectively. The blocking ring 320 is used for sleeving the hydrogen pipeline 110. The blocker ring 320 may have an interference fit with the hydrogen pipe 110. The blocking ring 320 is spaced apart from the sleeve 120. The blocker ring 320, the end of the sleeve 120, and the hydrogen pipe 110 between the blocker ring 320 and the end of the sleeve 120 form a receiving groove. In the first chamber 210, the first output duct 281 and the third output duct 285 extend toward between the blocker ring 320 and the sleeve 120. In the second chamber 220, the second output duct 283 and the fourth output duct 287 extend towards between the blocker ring 320 and the sleeve 120. Therefore, when the hydrogen concentration in the first chamber 210 or the second chamber 220 is greater than the preset value, the first output duct 281 and the third output duct 285 may inject the first medium 232 and the second medium 242 to the receiving tank located in the first chamber 210, or the second output duct 283 and the fourth output duct 287 may inject the first medium 232 and the second medium 242 to the receiving tank located in the second chamber 220, so as to achieve the purpose of rapidly solidifying and sealing the end of the sleeve 120.
In one embodiment, the edge of the blocking ring 320 is provided with an extension 330 extending toward one side. The extension 330 may be a sheet structure. The extension 330 may be integrally formed with the blocker ring 320. When the blocking ring 320 is sleeved on the hydrogen pipe 110 such that the extension portion 330 contacts with the end portion of the sleeve 120, the blocking ring 320, the end portion of the sleeve 120 and the extension portion 330 form an accommodating chamber 350, and the top of the accommodating chamber 350 has an opening 340. In the first chamber 210, the first output duct 281 and the third output duct 285 extend toward the opening 340, thereby facilitating the input of the first medium 232 and the second medium 242 to the opening 340. In the second chamber 220, the second output duct 283 and the fourth output duct 287 extend toward the opening 340, thereby facilitating the input of the first medium 232 and the second medium 242 to the opening 340. The first medium 232 and the second medium 242 can be cured in the accommodating cavity 350, the end of the sleeve 120 can be sealed quickly, the first medium 232 and the second medium 242 can be prevented from leaking, and the sealing efficiency can be improved.
In one embodiment, the blocker ring 320 has a ramped surface 342 at the opening 340 that slopes toward the sleeve 120. The first medium 232 and the second medium 242 can be slid into the receiving cavity 350 by the bevel 342.
In one embodiment, the cross-sectional area of the receiving cavity 350 becomes gradually larger from the bottom of the receiving cavity 350 to the top of the receiving cavity 350 in the horizontal direction. Therefore, after the first medium 232 and the second medium 242 enter the accommodating cavity 350, the liquid level at the bottom of the accommodating cavity 350 rises rapidly, so as to seal the end of the sleeve 120 rapidly, and achieve the purpose of saving the first medium 232 and the second medium 242.
In one embodiment, the first medium 232 is an acrylic modified epoxy and the second medium 242 is a hardener. The first medium 232 may also be an epoxy resin. The first medium 232 and the second medium 242 may constitute an AB glue.
