Description

Technical Field

[0001] This utility model relates to the field of hydrogen energy transportation technology, specifically a hydrogen energy transportation safety protection device. Background Technology

[0002] Hydrogen energy, as a highly promising clean energy source, plays a crucial role in the global energy transition. Its combustion product is only water, and its zero carbon emissions make it an ideal energy choice for addressing environmental pollution and climate change challenges. Its applications in automobiles, power generation, and other fields are becoming increasingly widespread. Hydrogen is a new energy source, but it is also a highly dangerous gas. It is not only highly flammable and explosive, but also has a certain degree of toxicity. When transporting hydrogen, it is often filled into hydrogen cylinders before being transported.

[0003] Traditional hydrogen cylinder transport devices are mostly simple in structure, with a certain gap between the hydrogen cylinder and the transport device. Therefore, collisions between the hydrogen cylinder and the transport device are common during transport, which can damage the hydrogen cylinder and potentially cause hydrogen leakage, leading to danger. In addition, the internal space of traditional hydrogen cylinders is relatively fixed, making it impossible to flexibly adjust the internal dimensions to safely securely place hydrogen cylinders of different sizes. Furthermore, the efficiency of fixing and disassembling hydrogen cylinders is low, seriously affecting transport efficiency. To address these issues, we propose a safety protection device for hydrogen energy transport. Utility Model Content
