Description

Technical Field

[0001] The invention belongs to the field of battery hydrogen storage systems, and in particular relates to a modular gaseous hydrogen storage unit structure. Background Art

[0002] Safety should be one of the most important design requirements for fuel cell hydrogen storage systems. Current fuel cell hydrogen storage systems have basically no explosion-proof properties. The hydrogen bottle is fixed on the hydrogen storage bracket with a clamp, and the outer surface is exposed to the atmosphere. In the event of external impact, not only is the bottle body easily penetrated by the external impact, but if it is hit by a burning explosive, it will also cause jet flames at the rupture of the hydrogen bottle. The high-temperature flame will continue to roast other nearby hydrogen bottles, causing secondary damage to other hydrogen bottles that have not been impacted by external forces. In order to avoid the above situation, innovative designs should be developed from the two aspects of "no leakage due to external impact" and "no combustion if leaked". "No leakage due to external impact" requires increasing the "armor" of the hydrogen storage system from the perspective of protection; "no combustion if leaked" requires analysis from the three elements of combustion, with a focus on finding solutions from the combustion aid (air) side. Summary of the invention

[0003] In view of this, the present invention aims to propose a modular gaseous hydrogen storage unit structure that can withstand greater impacts and collisions, effectively reduce the initial collision velocity of external force impacts, and protect hydrogen bottles.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A modular gaseous hydrogen storage unit structure, comprising a cover, an upper cladding block, a hydrogen bottle, a lower cladding block, a base, a fixing hoop and fixing bolts;

[0006] The hydrogen bottle is arranged between the upper covering block and the lower covering block to form an integral body 1, and the integral body 1 is installed on the base through a fixed clamp to form an integral body 2. The cover shell covers the integral body 2 and is connected to the base of the integral body 2 through fixing bolts to form a unit structure.

[0007] Furthermore, the base includes a flat plate and a support; the support is mounted on the flat plate, and the number of the supports is at least 2; the end surface of the support is crescent-shaped, which fits the contour of the hydrogen bottle;

[0008] The number of the fixing hoops corresponds to the support; the support is provided with a channel for the fixing hoops to pass through, and the fixing hoops bypass the hydrogen bottle and the support for fixing.

[0009] Further, the upper cladding block corresponds to the lower cladding block;

[0010] The upper covering block is provided with a plurality of blocks, which can cover the hydrogen bottle and avoid the position of the fixed clamp at the same time.

[0011] Furthermore, the cover is made of carbon fiber or high-strength titanium alloy, and the cover is in a U-shaped structure as a whole, forming an outermost wrapping for the hydrogen bottle;

[0012] The bottom of the cover shell is provided with a connecting portion which is bolted to the base.

[0013] Furthermore, the upper covering block and the lower covering block are made of a lightweight flame-retardant porous medium material and have a U-shaped structure. The upper covering block and the lower covering block are bonded together by an adhesive to cover the hydrogen bottle.

[0014] Compared with the prior art, the modular gaseous hydrogen storage unit structure described in the present invention has the following advantages:

[0015] The present invention provides a modular gaseous hydrogen storage unit structure. The high-strength cover can withstand large impacts and collisions, and can effectively reduce the initial collision velocity of external force impacts. The special-shaped flame-retardant lightweight coating block has the characteristics of foam plastics. It is not only lightweight, but also forms a layer of low air density space around the hydrogen bottle. Even if the burning explosive penetrates the bottle body, it is not easy to burn and catch fire due to the thin air, thus avoiding the occurrence of secondary damage. This structure has obvious modular characteristics and can be easily expanded to multi-bottle application scenarios. BRIEF DESCRIPTION OF THE DRAWINGS
