Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen fuel cells, in particular to a combined hydrogen-electric module. Background Art

[0002] Combined hydrogen-electric modules refer to the combination of multiple hydrogen fuel cell units, hydrogen storage tanks, and related control and electrical components to form an integrated system. This modular design can provide higher energy density and power output, and can also better adapt to different application requirements. Combined hydrogen-electric modules are usually used to drive electric vehicles, power backup energy systems, or provide electricity for industrial purposes. This design makes hydrogen energy systems more flexible, efficient, and easier to integrate into existing equipment or infrastructure.

[0003] When using the existing combined hydrogen-electric module, it is generally necessary to manually fix the position of the hydrogen-electric module using tools. The whole process will consume a lot of time and is relatively troublesome. In addition, the water generated by the existing combined hydrogen-electric module after use will be discharged through the drainage pipe. At this time, incompletely reacted hydrogen will also be discharged from the drainage pipe, resulting in a decrease in the utilization rate of hydrogen. Therefore, it is necessary to provide a combined hydrogen-electric module to solve the above technical problems. Utility Model Content

After the gas enters the airbag through the air ducts, the airbag will drive the fixing block to start sliding in the slide groove on the mounting plate during the inflation process, thereby effectively ensuring that the fixing block can fix the position of the hydrogen battery pack, further ensuring the normal operation of the hydrogen battery module.

[0007] Preferably, the upper ends of the hydrogen storage box and the drainage box are hinged with a plurality of evenly distributed fixing rods, and the upper ends of the fixing rods are threadedly connected with nuts.

Stability. In addition, after the hydrogen battery pack starts working, it will produce a steady stream of water.

When there is no water entering the floating plate inside the drainage box, the buoyancy of the float will be less than the gravity of the load-bearing block, and the second piston will block the water outlet. After the water source continuously enters the drainage tank, the float will increase with the increase of the buoyancy of the float, and finally the buoyancy will be greater than the gravity of the load-bearing block. The float will slide upward and drive the second piston to leave the water outlet, so that the water produced by the reaction will be discharged normally. Because hydrogen is insoluble in water, the water produced by the reaction can be isolated from the hydrogen through the above operation, which effectively avoids the leakage of hydrogen during the reaction.

[0029] Specifically, both mounting plates 9 are provided with insertion holes, and both air ducts 7 are inserted into the insertion holes on the mounting plates 9. After the gas enters the airbag 8 through the air duct 7, the airbag 8 will drive the fixing block 10 to start sliding in the slide groove on the mounting plate 9 during the inflation process, thereby effectively ensuring that the fixing block 10 can fix the position of the hydrogen battery pack 12, further ensuring the normal operation of the hydrogen power module.

[0030] Specifically, the upper ends of the hydrogen storage box 17 and the drainage box 18 are hinged with multiple evenly distributed fixing rods 26, and the upper ends of the fixing rods 26 are threadedly connected with nuts 27. The use of the fixing rods 26 and the nuts 27 can improve the stability of the hydrogen battery pack 12 and effectively ensure the normal operation of the hydrogen power module.

[0031] Specifically, a plurality of evenly distributed snap-in grooves are provided on the front and rear outer walls of the two fixing blocks 10, and the position of each snap-in groove corresponds to the position of the fixing rod 26. The fixing rod 26 can be snapped into the snap-in groove on the outer wall of the fixing block 10, and then the nut 27 is rotated, thereby effectively improving the stability of the hydrogen battery pack 12 and ensuring the normal operation of the hydrogen battery module.

[0032] Specifically, a sealing sleeve 16 is installed on the inner wall of the hydrogen pipe 15, and the upper end of the intake pipe 19 is connected to the lower end of the hydrogen pipe 15. The use of the sealing sleeve 16 can effectively prevent hydrogen from leaking when passing through the intake pipe 19 and the hydrogen pipe 15.

[0033] Specifically, a groove is provided on the inner wall at the lower end of the drainage box 18, and a water outlet is provided on the inner wall at the lower end of the groove.

[0035] Working principle: When the hydrogen power module is installed, the hydrogen battery pack 12 will be slowly placed on the support plate 6. During this process, the first piston 4 will start to move downward inside the piston box 3 under the action of the connecting rod 5. At this time, the gas inside the piston box 3 enters the air bag 8 through the air guide tube 7. During the process of the air bag 8 slowly filling, the fixing block 10 will start to slide in the groove on the mounting plate 9 until the hydrogen battery pack 12 is stably fixed between the two fixing blocks 10. After the installation of the hydrogen battery pack 12 is completed, the hydrogen battery pack can be raised by clamping multiple fixing rods 26 in the corresponding clamping grooves on the fixing block 10 and then turning the nut 27. 12 has stability. After the hydrogen battery pack 12 starts working, it will produce a steady stream of water. Under the action of the drain pipe, the water will be discharged into the interior of the drainage box 18. When there is no water entering the floating plate 20 inside the drainage box 18, the buoyancy of the float 22 will be less than the gravity of the load-bearing block 24, and the second piston 25 will block the water outlet. After the water source continuously enters the drainage box 18, the float 20 will increase with the increase of the buoyancy of the float 22. Finally, the buoyancy will be greater than the gravity of the load-bearing block 24, and the float 20 will slide upward to drive the second piston 25 to leave the water outlet, so that the water produced by the reaction will be discharged normally. This is the entire working process of a combined hydrogen-electric module.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
