Vehicle-mounted liquid hydrogen cylinder supporting structure

Abstract

The invention belongs to the technical field of vehicle-mounted hydrogen cylinders, and particularly relates to a vehicle-mounted liquid hydrogen cylinder supporting structure. The structure comprises an outer bottle and an inner bottle, the inner bottle is installed in an inner cavity of the outer bottle, first hoops are fixedly installed on the two sides of the top of the inner cavity of the outer bottle, second hoops are fixedly installed on the two sides of the bottom of the inner cavity of the inner bottle, and the first hoops and the second hoops which correspond to each other up and down are fixed through bolts and nuts. A heat preservation layer is arranged between the inner bottle and the outer bottle, the heat preservation effect can be effectively improved through a double-layer vacuum heat preservation plate layer, a heat preservation cotton layer and a polystyrene plate layer, and therefore the low-temperature environment is kept; and meanwhile, the vacuum degree is monitored through a vacuum sensor, and when the vacuum degree is lower than a preset value, vacuumizing can be automatically conducted again, so that a relatively high vacuum degree is guaranteed, the heat preservation effect can be further achieved, the influence of external factors on fuel in the inner bottle is greatly reduced, the evaporation capacity is reduced, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted hydrogen cylinders, in particular to a support structure for vehicle-mounted liquid hydrogen cylinders. Background technique [0002] Hydrogen, as an important energy material, may be the first to obtain large-scale application in the transportation field in the civilian field, replacing traditional fuel vehicles. However, the storage and transportation of hydrogen has always been the bottleneck problem hindering the large-scale application of hydrogen energy. From the perspective of application economy and cost, the use of liquid hydrogen storage and transportation has great practical significance for the promotion of hydrogen energy. Liquid hydrogen storage and transportation containers are divided into ground fixed containers, mobile transport containers, and liquid hydrogen cylinders used as fuel for hydrogen vehicles. Very low level and relatively mature application at home and abroa...

Problems solved by technology

[0003] In the process of realizing the vehicle-mounted hydrogen gas cylinder, there are often the following disadvantages. During the support process, the vehicle-mounted hydrogen gas cylinder often shakes with the shaking of the vehicle, resulting in the shaking of the hydrogen energy. The violent shaking affects the use effect and is also prone to danger. , and the raw materials in the existing on-board hydrogen cylinders are easy to evaporate, resulting in a certain amount of waste
