Description

Technical Field

[0001] This utility model belongs to the technical field of hydrogenation devices, and in particular a hydrogenation device with a preheating function. Background Technology

[0002] With industrial development, the demand for petroleum is increasing, and industrial pollution is becoming more and more serious, leading to a new energy crisis. Therefore, it is necessary to find raw materials that can replace petroleum. Hydrogen has high combustion efficiency; burning the same mass of hydrogen produces about three times the heat of gasoline, and the combustion product is water, making it the cleanest energy source in the world.

[0003] Existing hydrogen refueling devices are prone to damage during use because hydrogen is flammable and explosive. Vehicles may accidentally touch or collide with the devices during refueling, causing them to tip over and become damaged. Furthermore, there is no effective way to reinforce hydrogen refueling stations of different sizes, which reduces their efficiency.

[0004] A search revealed a Chinese patent document (authorization announcement number CN215174147U) regarding an anti-drag device for hydrogen refueling nozzles at hydrogen refueling stations. During use, springs two and three prevent the hydrogen refueling tube from being dragged too far. The device's application is broadened by a fixing component and a clamping component, allowing it to be used with hydrogen refueling tubes of different diameters. This design includes a moving component for easy movement and fixation, offering greater flexibility. However, this device suffers from the problem of not effectively reinforcing the hydrogen refueling station during use, thus reducing its efficiency. Utility Model Content
