Flexible connecting device for IV-type tube bundle bottle and container frame

Abstract

The invention discloses a flexible connecting device for an IV-type tube bundle bottle and a container frame. The device comprises a damping block, an anti-rotation block, a lining, an upper clamping block, a lower clamping block and the like. The damping block matches the anti-rotation block to flexibly control the circumferential rotation of the IV-type tube bundle bottle. The lining is combined with the upper clamping block and the lower clamping block to limit the axial movement of the IV-type tube bundle bottle. Aiming at the characteristic that the joint of a boss structure of the IV-type tube bundle bottle and a plastic inner container / composite material winding layer is easy to lose efficacy, one end of the IV-type tube bundle bottle of the container is allowed by the device to axially move within a small range, restraining force borne by the tube bundle bottle during expansion / contraction is released, meanwhile, the damping block is extruded by utilizing the circumferential rotation trend of a bottle body to consume energy, and a torque borne by the joint of the boss structure and the plastic liner / composite material winding layer is reduced. According to the device, the stress condition of the IV-type tube bundle bottle in a container can be improved, so that the damage and failure risks of the IV-type tube bundle bottle are reduced.

Description

technical field [0001] The invention relates to the field of normal-temperature compressed hydrogen storage and transportation equipment, in particular to a flexible connection device for IV-type tube bundle bottles and container frames. Background technique [0002] The large-capacity normal temperature and high pressure type IV hydrogen storage tube bundle container is a safe, economical, efficient and flexible hydrogen road transportation solution, and is a key technology to promote the development of hydrogen energy in China. Compared with traditional Type I, Type II, and Type III tube bundle containers, the advantages of Type IV tube bundle containers are: stronger hydrogen storage and transportation capacity, lower hydrogen transportation costs and longer service life of tube bundle bottles. [0003] At present, the IV-type tube bundle bottle and the container frame are rigidly connected, that is, the necks of the boss structures at both ends of the tube bundle bottle ...
