DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0026] A safe hydrogenation equipment housing, such as Figure 2 - Figure 5 As shown, it includes an outer shell 10, an inner shell 11, a hydrogen adsorption component 12 and two snap-fitting parts 14. The inner shell 11 located in the cavity of the outer shell 10 is fixedly connected to the outer shell 10. The outer wall surface of the inner shell 11 and the inner wall surface of the outer shell 10 form a chamber. The hydrogen adsorption component 12 is detachably connected to the inner shell 11. The two walls of the outer shell 10 are movably connected to the same snap-fitting parts 14. A pressure relief protection device is arranged in the cavity of the inner shell 11. The pressure relief protection device includes a connecting pipe 13, an exhaust pipe 16 and a second pressure relief part 20. The connecting pipe 13 located in the cavity of the inner shell 11 is fixedly connected to the inner shell 11. The connecting pipe 13 is "L"-shaped. Both ends of the connecting pipe 13 are connected to the same snap-fitting parts 14. An exhaust hole adapted to the exhaust pipe 16 is opened on the surface of the connecting pipe 13. The exhaust The tube 16 is embedded in the exhaust hole and fixedly connected to the connecting tube 13, the second pressure relief member 20 is embedded in the exhaust pipe 16 and movably connected to the exhaust pipe 16, the pressure relief protection device also includes a connecting pipe 15 and a fixing plate 17, the connecting pipe 13 is nested in the cavity of the connecting pipe 15, the connecting pipe 15 is fixedly connected to the connecting pipe 13, a connecting hole 18 adapted to the exhaust pipe 16 is provided on the surface of the fixing plate 17, the exhaust pipe 16 is embedded in the connecting hole 18 and fixedly connected to the fixing plate 17, the pressure relief protection device includes a first pressure relief member 23, the bottom surface of the second pressure relief member 20 is provided with a sliding groove 22 adapted to the first pressure relief member 23, the first pressure relief member 23 is embedded in the sliding groove 22, the first pressure relief member 23 is movably connected to the second pressure relief member 20, and the surface annular array of the second pressure relief member 20 has multiple groups of air permeable grooves 21.

[0027] Specifically, when in use, the operator connects the clamping member 14 through the external hydrogenation component, and the hydrogen is input into the cavity of the connecting pipe 13 through the clamping member 14 through the external hydrogenation component. The hydrogen is pressed into the cavity of the connecting pipe 13 by pressurization, and the hydrogen is input to the other end through the connecting pipe 13. If the hydrogen is pressurized and transported through the connecting pipe 13, the gas pressure in the cavity of the connecting pipe 13 may be over-pressured, causing the connecting pipe 13 to rupture. By connecting the exhaust pipe 16 to the surface of the connecting pipe 13, the second pressure relief member 20 is embedded in the exhaust pipe 1 6, the first pressure relief member 23 is embedded in the sliding groove 22 and is slidably connected to the second pressure relief member 20. When the input hydrogen pressure is too large and the inflow of hydrogen at the input end and the output end is greater than the outflow, the hydrogen that has not flowed out will accumulate in the cavity of the connecting pipe 13, causing the pressure in the cavity of the connecting pipe 13 to increase. At this time, the hydrogen will first squeeze the first pressure relief member 23, and the first pressure relief member 23 is elastically connected to the limit plate 25 through the spring 24. The first pressure relief member 23 is subjected to the pressure from the hydrogen and moves in the direction of the limit plate 25. A gap is formed between the first pressure relief member 23 and the second pressure relief member 20, and hydrogen flows out through the gap, and the outflowing hydrogen is discharged through the breathable groove 21, so as to relieve the pressure in the cavity of the connecting pipe 13, thereby avoiding the occurrence of hazards and personal injuries caused by excessive pressure in the cavity of the connecting pipe 13. By arranging the second pressure relief member 20 to be slidably connected with the fixing plate 17, when the first pressure relief member 23 is completely opened and the pressure of the hydrogen in the cavity of the connecting pipe 13 is still overpressured, the second pressure relief member 20 will be lifted up at this time, because the limit The limiting plate 25 is elastically connected to the fixed plate 17, and the lifted second pressure relief member 20 pushes the limiting plate 25 to move in the direction away from the fixed plate 17, so as to separate the second pressure relief member 20 from the exhaust pipe 16, and release the air pressure in the cavity of the connecting pipe 13. By setting the second pressure relief member 20 and the first pressure relief member 23, the hydrogen in the cavity of the connecting pipe 13 is released in stages, thereby achieving pressure relief grading and avoiding waste of resources. At the same time, the connecting pipe 13 is prevented from rupturing due to excessive pressure in the cavity, thereby increasing the safety risk.

[0028] like Figure 4 and Figure 5As shown, the pressure relief protection device also includes multiple groups of tension springs 19 and limiting plates 25. The tension spring 19 located on the top surface of the fixed plate 17 is connected to the fixed plate 17, and the other end of the tension spring 19 is connected to the limiting plate 25. The limiting plate 25 is elastically connected to the fixed plate 17. The second pressure relief member 20 located on the bottom surface of the limiting plate 25 is fixedly connected to the limiting plate 25. The pressure relief protection device also includes multiple groups of guide columns 27 and multiple groups of nuts 28. The surface of the limiting plate 25 is provided with a through hole adapted to the guide column 27. One end of the guide column 27 passes through the through hole and the tension spring 19 and is fixedly connected to the fixed plate 17. The other end is threadedly connected to the nut 28, and the guide column 27 is slidably connected to the limit plate 25. The pressure relief protection device also includes a semi-threaded bolt 26. The surface of the limit plate 25 is provided with a movable hole adapted to the semi-threaded bolt 26. The semi-threaded bolt 26 passes through the movable hole and is threadedly connected to the first pressure relief component 23. The semi-threaded bolt 26 is slidably connected to the limit plate 25. The pressure relief protection device also includes a spring 24. One end of the spring 24 is connected to the first pressure relief component 23, and the other end of the spring 24 is connected to the bottom surface of the limit plate 25. The semi-threaded bolt 26 also passes through the spring 24 and is movably connected to the spring 24.

[0029] Specifically, when in use, the first pressure relief member 23 is elastically connected to the limit plate 25 through the spring 24. When the pressure in the cavity of the connecting pipe 13 is less than the elastic force of the spring 24 on the first pressure relief member 23, the first pressure relief member 23 fits with the bottom surface of the second pressure relief member 20. When the pressure in the cavity of the connecting pipe 13 is greater than the elastic force of the spring 24 on the first pressure relief member 23, the hydrogen will push the first pressure relief member 23 along the path of the semi-threaded bolt 26 toward the wall surface of the limit plate 25, thereby realizing the automatic opening and closing of the first pressure relief member 23 and automatic pressure relief. The limit plate 25 is elastically connected to the fixed plate 17 through the tension spring 19. The tension spring 19 pulls the limit plate 25 closer to the fixed plate 17. When the connecting pipe 13 is in a closed position, the limit plate 25 is pulled closer to the fixed plate 17. When the hydrogen pressure in the 3 chamber is too high, the second pressure relief member 20 can be pushed to move in the direction away from the fixed plate 17. The second pressure relief member 20 drives the limit plate 25 to move and stretch the tension spring 19. When the air pressure in the connecting pipe 13 chamber is less than the tension of the tension spring 19 on the limit plate 25, the second pressure relief member 20 blocks the exhaust pipe 16 to avoid hydrogen leakage and waste of resources. The two ends of the tension spring 19 are respectively disassembled and connected to the fixed plate 17 and the limit plate 25. The operator can replace the tension spring 19 with different elastic coefficients according to the hydrogen pressure in the connecting pipe 13 chamber as needed, so that the pressure relief protection device can work normally, and at the same time realize a variety of use environments of the machine and improve the use efficiency of the machine.

[0030] Working principle: The operator connects the snap-fitting part 14 through the external hydrogenation component, and the hydrogen is input into the cavity of the connecting pipe 13 through the snap-fitting part 14 through the external hydrogenation component. The hydrogen is pressed into the cavity of the connecting pipe 13 by pressurization, and the hydrogen is input to the other end through the connecting pipe 13. If the hydrogen is pressurized and transported through the connecting pipe 13, the air pressure in the cavity of the connecting pipe 13 may be over-pressured, causing the connecting pipe 13 to rupture. By connecting the exhaust pipe 16 to the surface of the connecting pipe 13, the second pressure relief part 20 is embedded in the exhaust pipe 16, and the first pressure relief part 23 is embedded in the sliding groove 22 and is slidably connected to the second pressure relief part 20. When the input hydrogen pressure is too large and the inflow of hydrogen at the input end and the output end is greater than the outflow, the hydrogen that has not flowed out will be in the connecting pipe. The hydrogen accumulates in the cavity of the connecting pipe 13, causing the pressure in the cavity of the connecting pipe 13 to increase. At this time, the hydrogen will first squeeze the first pressure relief piece 23, and the first pressure relief piece 23 is elastically connected to the limit plate 25 through the spring 24. The first pressure relief piece 23 is subjected to the pressure from the hydrogen and moves in the direction of the limit plate 25. A gap is formed between the moving first pressure relief piece 23 and the second pressure relief piece 20, and the hydrogen flows out through the gap. The hydrogen that flows out is then discharged through the breathable groove 21, and the pressure in the cavity of the connecting pipe 13 is relieved. The second pressure relief piece 20 is slidably connected to the fixed plate 17. When the first pressure relief piece 23 is completely opened and the pressure of the hydrogen in the cavity of the connecting pipe 13 is still overpressure, the second pressure relief piece 20 will be lifted at this time because the limit plate 25 and the fixed plate 17 are connected. The fixed plate 17 is elastically connected, and the lifted second pressure relief member 20 pushes the limiting plate 25 to move in the direction away from the fixed plate 17, so as to separate the second pressure relief member 20 from the exhaust pipe 16, and relieve the air pressure in the cavity of the connecting pipe 13. The first pressure relief member 23 is elastically connected to the limiting plate 25 through the spring 24. When the pressure in the cavity of the connecting pipe 13 is less than the elastic force of the spring 24 on the first pressure relief member 23, the first pressure relief member 23 fits with the bottom surface of the second pressure relief member 20. When the pressure in the cavity of the connecting pipe 13 is greater than the elastic force of the spring 24 on the first pressure relief member 23, the hydrogen will push the first pressure relief member 23 to move along the path of the semi-threaded bolt 26 toward the wall surface of the limiting plate 25, so as to realize the automatic opening and closing of the first pressure relief member 23 and the automatic relief. The limit plate 25 is elastically connected to the fixed plate 17 through the tension spring 19. The tension spring 19 pulls the limit plate 25 closer to the fixed plate 17. When the hydrogen pressure in the cavity of the connecting pipe 13 is too large, the second pressure relief member 20 can be pushed to move in the direction away from the fixed plate 17. The second pressure relief member 20 drives the limit plate 25 to move and stretches the tension spring 19. When the gas pressure in the cavity of the connecting pipe 13 is less than the tension of the tension spring 19 on the limit plate 25, the second pressure relief member 20 blocks the exhaust pipe 16. The two ends of the tension spring 19 are respectively disassembled and connected to the fixed plate 17 and the limit plate 25. The operator can replace the tension spring 19 with different elastic coefficients according to the hydrogen pressure in the cavity of the connecting pipe 13, so that the pressure relief protection device can work normally.
