Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen storage, and in particular to a hydrogen storage device with a protective function. Background Art

[0002] Hydrogen energy refers to the use of hydrogen as a form of energy. Hydrogen can be produced in a variety of ways, such as electrolysis of water, natural gas reforming, etc. The basic principle is to use hydrogen and oxygen to react chemically to release chemical energy. The only product in this process is water. Therefore, hydrogen energy is considered to be a clean energy source. The combustion calorific value of hydrogen is about three times that of gasoline, which means that when using the same mass of fuel, hydrogen can release more energy. Hydrogen is usually produced and then transported to places where hydrogen is needed by special vehicles. There are many ways to transport hydrogen. The more commonly used methods are: high-pressure gaseous transportation, liquid hydrogen transportation, and solid-state hydrogen storage transportation. Currently, the most commonly used method is high-pressure gaseous transportation. This transportation method has low operating costs and mature hydrogen production technology. The high-pressure gaseous transportation method is to fill a large amount of hydrogen into a gas cylinder with a high pressure, and then transport it by container or long-tube trailer.

[0003] The patent entitled "A Hydrogen Storage Device with a Protective Structure" with authorization number CN117489972B mentions a device for protecting hydrogen storage devices during the transportation of hydrogen, including an arc-shaped sliding block sliding in a buffer arc groove, a storage cylinder placed on a buffer member, and the buffer cylinder rotates on a support column through a ring. When the storage cylinder slides on the buffer arc groove during transportation, a buffer spring is bent and arranged in the buffer arc groove to push the sliding of the sliding block and slow down the sliding of the sliding block. However, when the storage cylinder shakes, the buffer springs on both sides push the sliding block, which may cause the sliding block to drive the storage cylinder to slide back and forth on the buffer groove, further aggravating the shaking of the storage cylinder. At the same time, the storage cylinder is placed vertically. When the amount of liquid hydrogen stored in the storage cylinder is large, the center of the storage cylinder will rise, which is not conducive to the sliding of the buffer member and the sliding block in the buffer arc groove.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the present invention provides a hydrogen storage device with a protective function, which has the following features:

[0016] Beneficial effects:

[0017] 1. By setting the frame one and the frame two, the frame one and the frame two are combined to form a hexagon, so that multiple shell components can be installed together to save space and be more stable. After the multiple shell components are slidably connected through the docking strips and the docking grooves, the shell components will not be separated from each other. The docking strips and the docking grooves are staggered around the circumference of the gas tank, so that the shell components can be installed at various angles during installation;

[0018] 2. By setting the rotating seat 1, the rotating seat 2 and the traction rope, when the installation arc seat is vibrated and drives the gas tank to slide, the traction rope pulls the rotating seat to limit the sliding range and angle of the installation arc seat. Since the installation base is set on the vehicle, the vibration amplitude in each direction is different when the vehicle is driving. The traction rope forms a triangle through the through hole 1, the through hole 2 and the rotating seat 2. When the installation arc seat slides, the rotating seat 1 and the rotating seat 2 rotate together to prevent the traction rope from being entangled with the rotating seat 1. At the same time, when the traction rope is pulled out, the rotating seat 2 pulls the movement trajectory of the traction rope to form an ellipse-like shape, thereby controlling the different sliding distances of the installation arc seat in two directions;

[0019] 3. By setting the spring and the rack, when the arc seat is installed to shake, the distance between the rotating seat 2 and the through hole 1 and the through hole 2 can only be close to or far away from each other. When the arc seat is installed to shake back and forth, the traction rope is tightened and loosened. When the traction rope is tightened, the two springs are in a compressed state, driving the winding wheel to rewind the traction rope. There will be no problem that one of the two springs is tightened while the other spring is stretched, and the two springs drive the winding wheel to rotate back and forth;

[0020] In the present invention, by setting a sliding buffer mechanism, the gas tank can be shaken and damped at multiple angles, and the degree of limitation is different according to the different vibration amplitudes in two directions. By setting a traction damping mechanism, traction can be performed when the mounting arc seat shakes to various positions, and the reciprocating vibration of the mounting arc seat will not be caused. Therefore, compared with the prior art, this hydrogen storage device with a protective function can enhance the shock absorption and protection of the gas tank while reducing the reciprocating vibration of the gas tank.
