Embodiment Construction

[0051] In order to make the technical means, creative features, achieved objects and effects of the present invention easy to understand and understand, the present invention is further described below.

[0052] see figure 1 , figure 2 , a lightweight and long-life composite hydrogen bottle, comprising a hydrogen bottle body, the hydrogen bottle body includes a bottle body 4, the bottle body 4 is a bottle body 4 composed of carbon fiber; the inner wall of the bottle body 4 is provided with a non-metal elastic Material Constructed Liner 1. By optimizing the structure of the traditional hydrogen cylinder, the invention effectively increases the working fatigue times of the cylinder, reduces the weight of the cylinder, and has low production cost and short manufacturing cycle. Since the inner tank 1 made of non-metallic elastic material, such as the explosion of the hydrogen cylinder, will not produce any metal fragments, the safety of the hydrogen cylinder is very high.

Abstract

The invention relates to the technical field of machines, in particular to a low-weight long-service-life composite material hydrogen cylinder. The hydrogen cylinder comprises a hydrogen cylinder body. The hydrogen cylinder body comprises a bottle main body. The bottle main body is made of carbon fibers. The inner wall of the bottle main body is provided with an inner container which is made of a nonmetal elastic material, and the inner container can be replaced repeatedly. According to the low-weight long-service-life composite material hydrogen cylinder, by optimizing a traditional hydrogen cylinder structure, the working fatigue frequency of the cylinder is effectively increased, and the service life of the cylinder is effectively prolonged; and meanwhile, the weight of the cylinder is lowered, production cost is low, and manufacturing cycle is short. Due to the fact that the inner container is made of the nonmetal elastic material, if the hydrogen cylinder is exploded, no metal scraps can be produced, and the using safety of the hydrogen cylinder is quite high.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a hydrogen cylinder. Background technique [0002] When the hydrogen cylinder of the prior art encounters the problems of high pressure operation and high fatigue times, the method of increasing the thickness of the inner liner and improving the bursting strength of the cylinder is generally adopted, thereby reducing the stress level of the inner lining. In this way, the weight of the gas cylinder is bound to increase dramatically, thereby reducing the overall performance of the hydrogen fuel cell system. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a lightweight and long-life composite material hydrogen cylinder and a manufacturing method thereof, so as to solve the above-mentioned technical problems. [0004] The technical problem solved by the present invention can be realized by the following technical solutions: [0005] A lightw...
