[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] A hydrogen generator with early warning function, such as Figure 1-Figure 5 As shown, it includes a shell 1, and a gas pipe 12 for outputting hydrogen is installed on the back of the shell 1 through bolts. The gas pipe 12 is connected to the internal hydrogen pipeline. The end of the gas pipe 12 located outside the shell 1 is threadedly connected to a connecting pipe 16. A sealing frame 13 is fixed to the back of the shell 1. The gas pipe 12 is located in the sealing frame 13. A sealing plate 21 is rotatably connected to one side of the sealing frame 13. A hydrogen gas detector 20 is snap-fitted to the back of the shell 1, and the detection head 18 of the hydrogen gas detector 20 is located in the sealing frame 13.

[0025] By installing a sealing frame 13 around the hydrogen output pipe, it will not block the connection between the connecting pipe 16 and the gas pipe 12, and the leaked hydrogen can be blocked inside the sealing frame 13 to prevent the hydrogen leakage from a large area. The leaked hydrogen is gathered to facilitate detection by the hydrogen gas detector 20 (model SGA-606B). When hydrogen leaks from the hydrogen output pipe, it can be discovered in time, with a better early warning function, reducing safety hazards.

[0026] like Figure 5 As shown, the side wall of the gas pipe 12 is rotatably connected to the mounting cylinder 14, the inner wall of the mounting cylinder 14 is fixed with an internal thread ring, one end of the connecting pipe 16 is connected and fixed with a connector 15, the connector 15 is plugged into one end of the gas pipe 12, and the outer wall of the connector 15 is provided with an external thread ring, which is threadedly connected to the internal thread ring.

[0027] The connecting pipe 16 is a pipe of the external hydrogen collection device. When connecting the connecting pipe 16 to the gas pipe 12, the installation cylinder 14 slides to one end of the gas pipe 12, and the connector 15 is plugged into the end of the gas pipe 12. The connector 15 and the gas pipe 12 are sealed, and then the installation cylinder 14 is rotated so that the inner wall of the installation cylinder 14 is screwed to the outer wall of the connector 15. There is no need to twist the connector 15 or the gas pipe 12, and the installation is simple and convenient.

[0028] like Figure 5 As shown, the connecting pipe 16 passes through the lower end of the sealing frame 13 , a sealing gasket 17 is clamped on the inner wall of the installation cylinder 14 , and the end of the connector 15 is squeezed and fitted with the sealing gasket 17 .

[0029] The connecting pipe 16 is inserted from the lower end of the sealing frame 13 . The sealing frame 13 can prevent the back of the hydrogen generator from pressing against the wall to squeeze the connecting pipe 16 , and protect the connecting pipe 16 from being squeezed and bent. The sealing gasket 17 increases the sealing between the connector 15 and the gas pipe 12 .

[0030] like Figure 2-Figure 3 As shown, a card seat 19 is fixed to the back of the shell 1, and the card seat 19 is set to be "U"-shaped. The card seat 19 is located on one side of the sealing frame 13, and a card plate is fixed to the back of the hydrogen gas detector 20, and the card plate is engaged with the card seat 19.

[0031] The hydrogen gas detector 20 is installed on one side of the sealing frame 13 via the clamping plate and the clamping seat 19, which is convenient for taking, installing and timely testing.

[0033] The upper end and one side of the hydrogen generator are detachable, and the internal components are all mounted on the mounting seat 3. When the components need to be inspected, the vertical plate 8 is pulled and the components are pulled out of the shell 1 through the mounting seat 3, the slide rail 6 and the sliding seat 7, thereby increasing the inspection space and facilitating inspection.

[0034] like Figure 4 As shown, a locking plate 9 is fixedly connected to one side of the mounting base 3, and an L-shaped plate 10 is fixedly connected to the inner wall of the shell 1. The locking plate 9 is docked with the L-shaped plate 10, and a locking column 11 is threadedly connected to the L-shaped plate 10. The end of the locking column 11 is plugged into the locking plate 9.

[0035] In order to increase the stability of the mounting base 3, the locking plate 9 on the mounting base 3 and the L-shaped plate 10 on the inner wall of the shell 1 can be docked, and then the locking column 11 is plugged and locked to fix the mounting base 3 in the shell 1. When pulling out the mounting base 3, first twist the locking column 11 to make one end of the locking column 11 disengage from the locking plate 9, and then the mounting base 3 can be pulled out.

[0036] The working principle of the hydrogen generator with early warning function provided by the utility model is as follows:

[0037] By installing a sealing frame 13 around the hydrogen output pipe, it will not block the connection between the connecting pipe 16 and the gas pipe 12, and the leaked hydrogen can be blocked inside the sealing frame 13, preventing the hydrogen leakage area from being large, and the leaked hydrogen is gathered to facilitate detection by the hydrogen gas detector 20. When hydrogen leaks from the hydrogen output pipe, it can be discovered in time, with a better early warning function, reducing safety hazards. The components inside the shell 1 are installed in the shell 1 by pulling the mounting seat 3, which is convenient for maintenance.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
