Description

Technical Field

[0001] This utility model relates to the field of hydrogen storage tank installation technology, specifically a hydrogen storage tank installation and fixing device. Background Technology

[0002] High-pressure hydrogen storage is currently the most mature and widely used hydrogen storage method. It mainly uses multi-layer composite containers to compress and store hydrogen. It is mainly used for on-board hydrogen storage. When installing on-board hydrogen storage cylinders, a fixing device is usually required for installation.

[0003] A search revealed that the announcement number is CN221763284U, entitled "A Hydrogen Storage Bottle Fixing Device, including a fixing frame." Research and analysis revealed that although it has the advantages of meeting the fixing and clamping requirements of hydrogen storage bottles of different sizes and reducing the cost of manpower and tooling during production, it also has the following disadvantages to a certain extent.

[0004] For example, during use, the hydrogen storage tank is fixed only at one point in the middle. When installed in a vehicle, which is usually outdoors, the vehicle is affected by high temperatures in hot weather, which can easily cause an explosion. In order to solve the above technical problems, we have designed a hydrogen storage tank installation and fixing device. Utility Model Content

[0005] The purpose of this utility model is to provide a hydrogen storage tank installation and fixing device with the advantage of heat dissipation. This solves the problem that when the device is used, it only fixes the hydrogen storage tank through a single middle position. When installed in a vehicle, which is usually outdoors, the hydrogen storage tank is affected by high temperatures in hot weather, which can easily lead to an explosion.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydrogen storage tank installation and fixing device, comprising a base plate, with fixing shells welded to the front and rear sides of the top of the base plate. A first damper is bolted to the inner cavity of the fixing shell, and a movable plate is bolted to the opposite side of the first damper. A first spring is welded to the front and rear sides of the inner cavity of the fixing shell, and the opposite side of the first spring is welded to the movable plate. A support is welded to the surface of the movable plate, and a positioning frame is bolted to the top of the support. A second damper is bolted to the opposite side of the positioning frame, and a connecting frame is bolted to the opposite side of the second damper. A second spring is welded to the surface of the connecting frame. The side of the second spring away from the connecting frame is welded to the support and the positioning frame respectively. A positioning ring is bolted to the opposite side of the connecting frame. The hydrogen storage tank body is welded to the inner cavity of the positioning ring. A mounting frame is bolted to the top of the base plate. A cooling component is installed on the top of the base plate. A mounting frame is welded to the surface of the mounting frame. A cooling fan is bolted to the inner cavity of the mounting frame. The cooling component includes a water tank. The bottom of the water tank is bolted to the base plate. A heat-absorbing spiral tube is sleeved on the surface of the hydrogen storage tank body. A pump body is bolted to the top of the water tank. A serpentine tube is installed in the inner cavity of the mounting frame.

[0007] Preferably, the cooling component includes a water tank, the bottom of which is connected to a base plate by bolts, a heat-absorbing spiral tube is fitted on the surface of the main body of the hydrogen storage tank, a pump body is connected to the top of the water tank by bolts, and a serpentine tube is installed in the inner cavity of the mounting frame.

[0008] Preferably, the pump body's suction pipe is connected to the water tank via a pipe, the pump body's discharge pipe is connected to the serpentine pipe via a pipe, the rear side of the serpentine pipe is connected to the heat-absorbing spiral pipe via a pipe, and the right side of the water tank is connected to the heat-absorbing spiral pipe via a pipe.

[0009] Preferably, a water inlet pipe is connected to the top of the left side of the water tank, and a first pipe cap is threaded onto the left side of the water inlet pipe.

[0010] Preferably, a drain pipe is connected to the bottom of the left side of the water tank, and a second pipe cap is threaded onto the left side of the drain pipe.

[0011] Preferably, a protective shell is fixedly fitted onto the surface of the main body of the hydrogen storage tank, and the heat-absorbing spiral tube is located inside the protective shell.

[0012] Preferably, the inner cavity of the fixed shell is connected to a guide rod by bolts, and the surface of the guide rod is slidably connected to the movable plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention places a positioning ring between two connecting frames, and then fixes the connecting frames and positioning ring together with bolts to secure the main body of the hydrogen storage tank. Bolts are also used to fix the support and positioning frame, which in turn support and reinforce the positioning ring and the main body of the hydrogen storage tank. The base plate is then installed inside the vehicle. When the vehicle vibrates during driving, the main body of the hydrogen storage tank will vibrate back and forth and up and down. This vibration causes the positioning ring and connecting frame to move up and down, which in turn drives a second damper to absorb the vibration and reduce its transmission. The second spring performs a telescopic motion to buffer the vibration. The main body of the hydrogen storage tank drives the connecting frame and positioning ring to move back and forth. The positioning ring drives the second damper, support, and positioning frame to move back and forth. The support drives the movable plate to move back and forth. The movable plate drives the first damper to perform damping motion to absorb vibration and reduce vibration transmission. The telescopic motion of the first spring buffers the vibration, which can prevent excessive transmission of vehicle body vibration to the main body of the hydrogen storage tank. It reduces the impact of external vibration on the main body of the hydrogen storage tank. After the vibration is reduced, it also prevents the gas outlet of the main body of the hydrogen storage tank from becoming loose at the joint of the connecting pipe.

[0015] When this invention is used in high-temperature weather, water is pumped from the water tank and injected into the serpentine tube. A cooling fan blows air onto the surface of the serpentine tube to cool the water inside. The cooled water flows into the heat-absorbing spiral tube, which cools the surface of the hydrogen storage tank body. This effectively prevents the surface temperature of the hydrogen storage tank body from becoming too high. The water that has absorbed heat flows back into the water tank for recycling, facilitating the normal use of the hydrogen storage tank body in high-temperature weather. Attached Figure Description

A heat-absorbing spiral tube 15 is fitted on the surface of the hydrogen storage tank body 13. By setting the heat-absorbing spiral tube 15, the surface of the hydrogen storage tank body 13 can be cooled, which can effectively prevent the surface temperature of the hydrogen storage tank body 13 from being too high. A pump body 20 is bolted to the top of the water tank 19. A serpentine tube 21 is installed in the inner cavity of the mounting frame 16.

[0022] Please see Figure 1 and Figure 4 The pump body 20's water intake pipe is connected to the water tank 19 via a pipe, the pump body 20's water outlet pipe is connected to the serpentine pipe 21 via a pipe, the rear side of the serpentine pipe 21 is connected to the heat absorption spiral pipe 15 via a pipe, and the right side of the water tank 19 is connected to the heat absorption spiral pipe 15 via a pipe. By setting up the pump body 20, the water in the water tank 19 can be easily circulated, which can facilitate the circulating cooling of the surface of the hydrogen storage tank body 13.

[0023] Please see Figure 1 and Figure 4A water inlet pipe is connected to the top left side of the water tank 19. By setting the water inlet pipe, it is easy to add water to the water tank 19. A first pipe cap is threaded on the left side of the water inlet pipe.

[0029] In use, the positioning ring 12 is placed between the two connecting frames 11, and then the connecting frames 11 and the positioning ring 12 are fixedly installed with bolts, thereby fixing the hydrogen storage tank body 13. The support 7 and the positioning frame 8 are fixed with bolts. The positioning ring 12 and the hydrogen storage tank body 13 are supported and reinforced by the connecting frame 11 and the support 7. Then, the base plate 1 is installed into the car. During installation, the mounting frame 16 is connected to the outside of the car. When the car vibrates, the hydrogen storage tank body 13 will vibrate back and forth and up and down. When the hydrogen storage tank body 13 vibrates up and down, the hydrogen storage tank body 13 drives the positioning ring 12 and the connecting frame 11 to move up and down. The connecting frame 11 drives the second damper 10 to perform damping movement to absorb the vibration and reduce the vibration transmission. The second spring 9 performs extension and contraction movement to buffer the vibration. When the hydrogen storage tank body 13 vibrates back and forth, the hydrogen storage tank body 13 drives the connecting frame 11 to move up and down. The positioning ring 12 moves back and forth, which in turn drives the second damper 10, support 7, and positioning frame 8 to move back and forth. The support 7 drives the movable plate 6 to move back and forth, and the movable plate 6 drives the first damper 3 to perform damping motion to absorb vibration and reduce vibration transmission. The first spring 4 performs extension and retraction motion to buffer the vibration. Through the above operations, the system provides vertical and horizontal vibration resistance. When used in high-temperature weather, the pump body 20 draws water from the water tank 19 and injects it into the serpentine tube 21. The cooling fan 17 blows air onto the surface of the serpentine tube 21 to cool the water inside. The cooled water flows into the heat-absorbing spiral tube 15, which cools the surface of the hydrogen storage tank body 13. This effectively prevents the surface temperature of the hydrogen storage tank body 13 from becoming too high. The water that has absorbed heat flows back into the water tank 19 for recycling, facilitating the normal use of the hydrogen storage tank body 13 in high-temperature weather.

[0030] In summary, this hydrogen storage tank mounting and fixing device, through the mounting frame 16, cooling fan 17, mounting bracket 18, water tank 19, pump body 20, and serpentine tube 21, solves the problem that when the device is used, the hydrogen storage cylinder is only fixed through a single middle position. When installed in a vehicle, which is usually outdoors and subject to high temperatures in hot weather, it is prone to explosion.
