Description

Technical Field

[0001] This invention relates to hydrogen energy transportation technology, and more particularly to a fixed protection device for long-distance transportation of hydrogen energy storage bottles. Background Technology

[0002] Currently, hydrogen energy refers to hydrogen gas, which is generally stored in hydrogen cylinders. Hydrogen cylinders are high-purity, high-efficiency, and highly safe hydrogen storage devices.

[0003] Patent document with application number "CN202210958466.7" discloses a hydrogen cylinder fixing device including a placement assembly, which comprises a placement frame, a locking block, an arc-shaped sliding block, and a pressing block. The locking block is connected to the placement frame, and the arc-shaped sliding block and the pressing block are mounted on the locking block. A fixing assembly includes a pressing block and a limiting rod. The pressing block is connected to the arc-shaped sliding block, and the limiting rod is connected to the pressing block. This device is simple and secure to fix, and can also be disassembled for transport and use.

[0004] Patent document with application number "CN201811052244.9" discloses a hydrogen cylinder fixing device with protective function, including a fixed base, a first shock-absorbing spring fixedly connected to the upper end of the fixed base, a shock-absorbing base fixedly connected to the upper end of the first shock-absorbing spring, a limiting groove provided at the upper end of the shock-absorbing base, a back plate fixedly connected to the upper end of the shock-absorbing base, a second fixing frame hinged to the right side of the front of the back plate via a hinge, and a fixing block fixedly connected to the side end of the first fixing frame; by setting the first and second shock-absorbing springs, the hydrogen cylinder is placed at the upper end of the limiting groove of the shock-absorbing base. When the hydrogen cylinder is subjected to external impacts or bumps, the first and second shock-absorbing springs can effectively dissipate most of the external force, protecting the hydrogen inside the cylinder from leakage and avoiding the threat to personal safety and crops from hydrogen leakage and explosion; the invention is reasonably designed, simple in structure, and suitable for promotion and widespread application.
