Description

Technical Field

[0001] The utility model belongs to the technical field of hydrogen energy, and specifically relates to a hydrogen energy storage device. Background Art

[0002] Compared with traditional energy, hydrogen energy is environmentally friendly and sustainable. It only produces water after chemical reaction, and has the characteristics of zero pollution, high efficiency, and suitable for long-distance transportation. Hydrogen storage is a bridge connecting hydrogen production and use, and plays an irreplaceable role in the development of hydrogen energy. Hydrogen energy can be stored in three states: gas, liquid, and solid. The storage process has low self-consumption, high energy density, and diverse production methods. So far, almost all hydrogen storage equipment and hydrogen transmission equipment are subject to hydrogen pressure, which is a pressure-bearing equipment among special equipment, among which gas cylinders are a more common type.

[0003] The hydrogen storage cylinders in the prior art are pressure vessels and have various models. The locations of the filling ports of different models are also different. Some are at the bottom of the bottle, and some are at the bottle mouth. This makes it impossible for some models of hydrogen storage cylinders to stand upright and can only be placed horizontally. During transportation, they not only take up space, but also because the cylinders themselves are cylindrical, they are very easy to roll and collide, making the hydrogen pressurization in the bottle dangerous. Utility Model Content

[0004] The purpose of the utility model is to provide a hydrogen energy storage device, which can make hydrogen storage cylinders with different filling port positions stand upright, thereby saving space occupied during transportation and handling, and can prevent the hydrogen storage cylinders from rolling due to horizontal placement, and can eliminate and buffer the impact force received by the hydrogen storage cylinders when they are bumped, thereby preventing the bottle body from rupturing and causing energy leakage, and avoiding the energy in the bottle from shaking significantly and causing pressurization.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A hydrogen energy storage device comprises a hydrogen storage cylinder, a fixing ring and an elastic plate, wherein the fixing ring is symmetrically fixedly connected to the outer wall of the hydrogen storage cylinder, the outer wall of the fixing ring is slidably connected to a sliding block in an array, the outer wall of the fixing ring is symmetrically fixedly connected to a partition plate located between two sliding blocks, both sides of the sliding block are symmetrically fixedly connected to a spring column 1, the sliding block is elastically connected to the partition plate through the spring column 1, one end of the sliding block is fixedly connected to a connecting rod 1, both ends of the elastic plate are fixedly connected to an L-shaped plate, one side of the L-shaped plate is symmetrically fixedly connected to a spring column 2, and the L-shaped plate is elastically connected to the connecting rod 1 through the spring column 2.

[0007] A hollow column is fixedly arranged at the bottom of the hydrogen storage cylinder, and a second connecting rod is fixedly connected to the outer wall of the hollow column in an array.

[0008] The hollow column is fixedly connected to one of the fixing rings via a second connecting rod.

[0009] One end of the L-shaped plate and one side of the second spring column is fixedly connected with a sliding rod.

[0010] The L-shaped plate is slidably connected to the connecting rod via a sliding rod.

[0011] An anti-collision head is symmetrically fixedly connected to the outer wall of the sliding block and located on one side of the spring column.

[0012] The technical effect achieved by the utility model is that hydrogen storage cylinders with different filling port positions can be placed upright, thereby saving space during transportation and handling, and can prevent the hydrogen storage cylinders from rolling due to horizontal placement, and can dissipate and buffer the impact force applied to the hydrogen storage cylinders when they are bumped, thereby preventing the bottle body from rupturing and causing energy leakage, and avoiding large shaking of the energy in the bottle causing pressurization.
