Hydrogen storage system

Abstract

The invention discloses a hydrogen storage system, the hydrogen storage system comprises a hydrogen storage tank and a hydrogen storage valve, the hydrogen storage tank comprises a surface layer, a tank body, an inner container, a tank plug and an upper cover, the surface layer, the tank body and the inner container are sequentially arranged from outside to inside, the tank body is upwards provided with a closing-up opening, the inner container is located below the closing-up opening, in an unopened state, the tank plug is contained in the closing-up opening, the upper cover is connected to the closing-up opening in a threaded mode, the surface layer is a fiber winding layer, the inner container is made of stainless steel, and the hydrogen storage valve comprises a valve body, a hand wheel, a first supporting rod, a second supporting rod, a cylindrical connecting part, pawls, a third supporting rod, a spiral groove, an armature, an electromagnetic coil, a piston, outlets, fan rib channels, one-way valves, a valve plate, a magnetic block, a first vertical groove, a second vertical groove and an electronic drive module.

Description

technical field [0001] The invention relates to the field of hydrogen storage, in particular to a hydrogen storage system. Background technique [0002] As a new energy source, hydrogen fuel plays an important role. With the reduction of existing gasoline energy sources and the pollution it produces, especially the smog phenomenon that people pay close attention to deeply affects the living standards of residents, the use of new energy sources is inevitable. It must be done; as a green energy, hydrogen fuel has been widely used, such as hydrogen fuel cells have been used in vehicles and other vehicles. [0003] 1. In actual use, the storage of hydrogen raw materials is a common technology, that is, hydrogen storage tanks are often used; in use, hydrogen storage valves are required for deflation, and the single-layer opening is relatively thin, such as only setting a one-way The valve or one-layer opening and closing structure is relatively thin; it cannot provide better sea...

AI Technical Summary

Problems solved by technology

[0003] 1. In actual use, the storage of hydrogen raw materials is a common technology, that is, hydrogen storage tanks are often used; in use, hydrogen storage valves are required for deflation, and the single-layer opening is relatively thin, such as only setting a one-way The valve or one-layer opening and closing structure is relatively thin; it cannot provide better sealing, stable long-term service life and safe use; and the double-layer opening and closing structure is often more complicated, such as the first air outlet, the second air outlet, etc. Adapted channels are often bent, which increases the difficulty of manufacturing and increases the cost

[0004] 2. In addition, the double-layer opening and closing structure requires double drives. If an additional manual emergency drive is added, it will become three drives. The structure is complicated and the cost is high

[0005] 3. The drive structure in the prior art often occupies a large size, which brings inconvenience to installation and adaptation, and increases the cost. Especially important, the existing technology in the hydrogen storage valve cannot add additional manual emergency in addition to the main drive drive

[0006] 4. The threaded installation structure in the prior art is simple and light, but after long-term use, it is easy to loose the thread, and the ordinary connection is not a big problem; but for the high-pressure storage tank, the loose threaded connection means leakage, and the gasket is also difficult. Mates with threads, so there is no good solution in the prior art

[0007] 5. The hydrogen storage valve in the prior art has only one external pipeline, that is, only one final outlet, which is difficult to adapt to the needs of multiple working conditions, and cannot achieve a better pressure relief effect

[0008] 6. The existing hydrogen storage valve is prone to loosening of the valve plate after being closed for a long time

[0009] 7. The existing hydrogen storage tank has insufficient safety protection performance
