Description

Technical Field

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

[0002] Hydrogen energy refers to a form of energy that uses hydrogen as a fuel. Hydrogen can be produced through various methods, such as electrolysis of water, natural gas reforming, etc. Its basic principle is to use the chemical reaction between hydrogen and oxygen to release chemical energy. The only product in this process is water. Therefore, hydrogen energy is considered a clean energy source. The calorific value of hydrogen combustion is about three times that of gasoline, which means that when using the same mass of fuel, hydrogen can release more energy. Usually, after hydrogen is produced, it is transported to the place where hydrogen is needed by special vehicles. There are various transportation methods for hydrogen, and the more commonly used methods are: high-pressure gaseous transportation, liquid hydrogen transportation, and solid-state hydrogen storage transportation. Currently, the most widely 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 involves filling a large amount of hydrogen into gas cylinders with high pressure inside, and then transporting it through container grids or long-tube trailers.

[0003] In the patent with the authorization number CN117489972B, titled "A Hydrogen Storage Device with a Protection Structure", a device for protecting the hydrogen storage device during hydrogen transportation is mentioned. It includes an arc-shaped sliding block sliding in a buffer arc groove, a storage cylinder placed on a buffer member, and a buffer cylinder rotating on a support column through a collar. When the storage cylinder slides on the buffer arc groove during transportation, a buffer spring is bent in the buffer arc groove to push the sliding block, slowing down the sliding of the sliding block. However, when the storage cylinder shakes, the buffer springs on both sides pushing the sliding block may cause the sliding block to drive the storage cylinder to slide back and forth on the buffer chute, further exacerbating 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 relatively large, it will cause the center of the storage cylinder to rise, which is not conducive to the sliding of the buffer member and the sliding block in the buffer arc groove.

[0011] Furthermore, a first rotating seat is rotatably arranged at the center of the bottom of the installation arc seat.

[0014] (III) Beneficial effects

[0015] Compared with the prior art, the present invention provides a hydrogen storage device with a protection function, having the following beneficial effects:

[0016] 1. By providing the first frame and the second frame, the first frame and the second frame are combined to form a hexagon, making it more space-saving and more stable when multiple outer shell components are installed together. Moreover, after the multiple outer shell components are slidably connected through the docking strips and docking grooves, the outer shell components will not separate from each other. The docking strips and docking grooves are arranged alternately around the circumference of the gas tank, enabling the outer shell components to be installed at various angles during installation;

[0017] 2. By setting the first rotating seat, the second rotating seat and the towing rope, when the installation arc seat is vibrated to drive the gas cylinder to slide, the towing rope restricts the sliding range and angle of the installation arc seat by towing the rotating seat. Since the installation base is set on the vehicle and the vibration amplitudes in all directions are different when the vehicle is running, the towing rope forms a triangle through the first through hole, the second through hole and the second rotating seat. When the installation arc seat slides, the first rotating seat and the second rotating seat rotate accordingly, preventing the towing rope from winding around the first rotating seat. At the same time, when the towing rope is pulled out, the movement track of the towing rope pulled by the second rotating seat forms a shape similar to an ellipse, thereby controlling the different sliding distances of the installation arc seat in two directions;

[0018] 3. By setting the springs and the rack, when the installation arc seat shakes, the distances between the second rotating seat and the first through hole and the second through hole can only get closer and farther. When the installation arc seat shakes back and forth, the towing rope is tightened and loosened. When the towing rope is tightened, both springs are in a compressed state, driving the winding wheel to wind the towing rope, and it will not occur that one spring is tightened while the other spring is stretched, and the problem that the two springs drive the winding wheel to rotate back and forth;

[0019] In the present invention, by setting the sliding buffer mechanism, the gas cylinder can be shaken and damped at multiple angles, and according to the different vibration amplitudes in two directions, the limiting degree is also different. By setting the towing damping mechanism, towing can be carried out when the installation arc seat shakes to each position, and it will not drive the installation arc seat to vibrate back and forth. Therefore, compared with the prior art, this hydrogen storage device with a protection function can enhance the damping and protection of the gas cylinder while reducing the reciprocating vibration of the gas cylinder.

After the first frame 4 and the second frame 5 are connected, they form a hexagon. The docking strip 6 and the docking groove 7 are arranged in a staggered manner. The first frame 4 and the second frame 5 are combined to form a hexagon, so that when multiple housing assemblies are installed together, more space is saved and it is more stable. Moreover, after multiple housing assemblies are slidably connected through the docking strip 6 and the docking groove 7, the housing assemblies will not separate from each other. The docking strip 6 and the docking groove 7 are arranged in a circumferential staggered manner around the gas tank 1, so that the housing assemblies can be installed at various angles during installation.

[0031] Please refer to Figures 1 to 4 , the sliding buffer mechanism further includes two slide rails 8 and two arc-shaped bases 9. The two slide rails 8 are installed on the mounting base 2.

The mounting arc seat 3 slides on the arc-shaped base 9 through the arc-shaped slideway 10. At the same time, when there is vibration in the direction perpendicular to the arc-shaped base 9, the arc-shaped base 9 slides on the slide rail 8.

[0032] Please refer to Figures 4 to 7, a rotating seat one 14 is rotatably arranged at the center of the bottom of the installation arc seat 3, and a rotating seat two 15 is rotatably arranged on the side of the rotating seat one 14. The rotating axis of the rotating seat one 14 is perpendicular to the installation arc seat 3, and the rotating axis of the rotating seat two 15 is perpendicular to the rotating seat one 14. The traction damping mechanism includes a through hole one 16, a through hole two 17, a traction rope 18 and a tension assembly.

The rotating seat one 14 is arranged above the through hole one 16, and the rotating seat one 14 does not contact the installation base 2. When the installation arc seat 3 is vibrated to drive the gas tank 1 to slide, the traction rope 18 limits the sliding range and angle of the installation arc seat 3 by pulling the rotating seat. Since the installation base 2 is arranged on the vehicle and the vibration amplitudes in all directions are different when the vehicle is driving, the traction rope 18 forms a triangle through the through hole one 16, the through hole two 17 and the rotating seat two 15. When the installation arc seat 3 slides, the rotating seat one 14 and the rotating seat two 15 rotate accordingly, preventing the traction rope 18 from being wound around the rotating seat one 14. At the same time, when the traction rope 18 is pulled out, the movement track of the rotating seat two 15 pulling the traction rope 18 forms a shape similar to an ellipse, thereby controlling the different slidable distances of the installation arc seat 3 in two directions.

[0033] Please refer to Figures 4 to 7 , the tension assembly includes a winding wheel 19, a gear 20, a sliding hole 21, a sliding rod 22 and a rack 24.

When the installation arc seat 3 shakes back and forth, the traction rope 18 is tightened and loosened. When the traction rope 18 is tightened, both springs 23 are in a compressed state, driving the winding wheel 19 to wind up the traction rope 18, and there will be no problem that one of the two springs 23 is tightened while the other spring 23 is stretched, and the two springs 23 drive the winding wheel 19 to rotate back and forth.
