[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-3 , the present utility model provides a technical solution: a purging structure based on cylinder replacement in a special gas cabinet, including a bracket 1. A gas cylinder main body 3 is movably installed inside the bracket 1. A workbench 2 is fixedly installed in the middle of the bracket 1. A rectangular groove 12 is opened inside the workbench 2. Convex blocks 10 are arranged on both the left and right sides inside the rectangular groove 12. At the same time, a spiral hole 13 is opened on the front side of the inner wall of the rectangular groove 12. A moving component 9 is slidably connected inside the rectangular groove 12. A handwheel 8 is fixedly connected to one side of the moving component 9 and located outside the workbench 2. At the same time, a purging pipe 14 is installed inside the moving component 9. A high-pressure blower 5 is installed on one side of the bracket 1. The lower end of the purging pipe 14 is connected to a corrugated pipe 7. At the same time, the lower end of the corrugated pipe 7 is connected to a conduit joint 6. The high-pressure blower 5 is communicated with the conduit joint 6 through a pipeline.
[0023] Through the rectangular groove 12, the moving component 9 can be installed. Since the handwheel 8 is fixedly connected to one side of the moving component 9, and the purging pipe 14 is installed inside the moving component 9. At the same time, the bottom of the purging pipe 14 is connected to the corrugated pipe 7. Then, by rotating the handwheel 8, the moving component 9 and the purging pipe 14 are driven to slide along the two convex blocks 10, so that the moving component 9 and the purging pipe 14 can adjust the direction, and thus adapt to gas cylinder main bodies 3 with different diameters. And by starting the high-pressure blower 5, since the high-pressure blower 5 is communicated with the conduit joint 6 through a pipeline, and the upper end of the conduit joint 6 is connected to the corrugated pipe 7, and the upper end of the corrugated pipe 7 is connected to the purging pipe 14. Therefore, the high-pressure air pressure is transported along the air pipe, the conduit joint 6, and the corrugated pipe 7 to the purging pipe 14, and the inner wall of the gas cylinder main body 3 is cleaned through the purging pipe 14.
[0024] Refer to Figure 1 , Figure 3 , a through hole 11 is opened in the middle of the moving component 9. A positioning ring 4 is installed on the top of the moving component 9. At the same time, the purging pipe 14 is installed inside the through hole 11. The moving component 9 is slidably connected to the outer surfaces of the two convex blocks 10. The two convex blocks 10 are fixedly installed on the left and right sides of the inner wall of the rectangular groove 12. At the same time, the outer surfaces of the two convex blocks 10 are coated with an anti-corrosion coating.
[0025] Through the positioning ring 4, the bottle mouth of the gas cylinder body 3 can be limited. Since the positioning ring 4 is installed on the top of the moving component 9, and a through hole 11 is opened in the middle of the moving component 9, and the purging pipe 14 is installed inside the through hole 11, the positioning ring 4 limits the bottle mouth of the gas cylinder body 3, and the purging pipe 14 can be inserted into the inside of the gas cylinder body 3, and the purging pipe 14 is kept in the central position of the gas cylinder body 3, thereby improving the purging work efficiency of the gas cylinder body 3.
[0026] Refer to Figure 2 , the positioning ring 4 is made of nylon material. At the same time, the positioning ring 4 is in a semi-circular arc shape, and the number of the positioning rings 4 is four. The four-core positioning rings 4 are all installed on the top of the moving component 9.
[0027] Since the positioning ring 4 is made of nylon material, the positioning ring 4 made of nylon material has good wear resistance, so as to prevent the positioning ring 4 from damaging the bottle mouth of the hydrogen energy gas cylinder when positioning the bottle mouth of the gas cylinder body 3, and further improving the service life of the gas cylinder body 3.
[0028] Refer to Figure 3 , the moving component 9 includes a mounting seat 901. The mounting seat 901 is slidably connected to the outer surfaces of the two bumps 10. A threaded rod 902 is sleeved on one side of the mounting seat 901, and grooves 903 are opened on both the left and right sides of the mounting seat 901. The threaded rod 902 is threadedly sleeved inside the spiral hole 13, and one end of the threaded rod 902 is fixedly connected to the handwheel 8. The four positioning rings 4 are annularly arranged on the top of the mounting seat 901.
[0029] Through the four positioning rings 4, the bottle mouth of the gas cylinder body 3 can be limited. Since the four positioning rings 4 are fixedly installed on the top of the mounting seat 901, at the same time, the threaded rod 902 is sleeved on one side of the mounting seat 901, and the threaded rod 902 is threadedly sleeved inside the spiral hole 13, so when the threaded rod 902 is rotated, under the action of the thread, the threaded rod 902 drives the mounting seat 901, the positioning ring 4 of the gas cylinder body 3, and the purging pipe 14 to slide along the two bumps 10 respectively, so that the moving component 9 and the purging pipe 14 can adjust the direction, and thus can adapt to gas cylinder bodies 3 with different diameters.
[0030] During operation, the moving component 9 can be installed through the rectangular groove 12. Since the handwheel 8 is fixedly connected to one side of the moving component 9, and a purging pipe 14 is installed inside the moving component 9, and a bellows 7 is connected to the bottom of the purging pipe 14, rotating the handwheel 8 drives the moving component 9 and the purging pipe 14 to slide along the two bumps 10, so that the moving component 9 and the purging pipe 14 can be adjusted in direction, thus adapting to gas cylinder bodies 3 with different diameters. And by starting the high-pressure blower 5, since the high-pressure blower 5 is connected to the conduit joint 6 through a pipeline, and the upper end of the conduit joint 6 is connected to the bellows 7, and the upper end of the bellows 7 is connected to the purging pipe 14, the high-pressure gas is then transported along the air pipe, the conduit joint 6, and the bellows 7 to the purging pipe 14, and the inner wall of the gas cylinder body 3 is cleaned through the purging pipe 14.
[0031] Through the positioning ring 4, the mouth of the gas cylinder body 3 can be limited. Since the positioning ring 4 is installed on the top of the moving component 9, and a through hole 11 is opened in the middle of the moving component 9, and the purging pipe 14 is installed inside the through hole 11, the positioning ring 4 limits the mouth of the gas cylinder body 3, and the purging pipe 14 can be inserted into the gas cylinder body 3, and the purging pipe 14 remains in the centered position of the gas cylinder body 3, thus improving the working efficiency of purging the gas cylinder body 3.
[0032] The positioning ring 4 is made of nylon material. The positioning ring 4 made of nylon material has good wear resistance, so as to prevent the positioning ring 4 from damaging the mouth of the hydrogen energy gas cylinder when positioning the mouth of the gas cylinder body 3, and further improving the service life of the gas cylinder body 3.
[0033] Through the four positioning rings 4, the mouth of the gas cylinder body 3 can be limited. Since the four positioning rings 4 are fixedly installed on the top of the mounting seat 901, and the threaded rod 902 is sleeved on one side of the mounting seat 901, and the threaded rod 902 is threadedly sleeved inside the spiral hole 13, rotating the threaded rod 902, under the action of the thread, the threaded rod 902 drives the mounting seat 901, the positioning ring 4 of the gas cylinder body 3, and the purging pipe 14 to slide along the two bumps 10, so that the moving component 9 and the purging pipe 14 can be adjusted in direction, thus adapting to gas cylinder bodies 3 with different diameters.
[0034] In summary, when the device rotates the handwheel 8, it drives the moving component 9 and the purging pipe 14 to slide along the two bumps 10, so that the moving component 9 and the purging pipe 14 can be adjusted in direction, thus adapting to gas cylinder bodies 3 with different diameters. And by starting the high-pressure blower 5, the high-pressure gas is transported along the air pipe, the conduit joint 6, and the bellows 7 to the purging pipe 14, and then the inner wall of the gas cylinder body 3 is purged through the purging pipe 14.
