Description

Technical Field

[0001] The invention relates to the technical field of hydrogen storage, and in particular to a mobile organic liquid hydrogen storage tank. Background Art

[0002] The principle of liquid organic hydrogen storage technology (LOHC for short) is to achieve hydrogen storage (chemical bonding) through the reversible reaction and hydrogenation reaction of unsaturated liquid organic matter such as certain olefins, alkynes or aromatic hydrocarbons and hydrogen, and to release hydrogen through dehydrogenation reaction. The mass hydrogen storage density is 5%-10%, and the hydrogen storage capacity is large. The hydrogen storage material is liquid organic matter, which can be transported at room temperature and pressure, which is convenient and safe.

[0003] When using liquid organic hydrogen storage technology to store hydrogen, a hydrogenation reactor is required to synthesize hydrogen and oil. When using hydrogen energy, a dehydrogenation reactor is used to release hydrogen. Hydrogen storage tanks are generally selected as hydrogen storage tools.

[0004] In the prior art, hydrogen storage tanks are of two types: vertical and horizontal. In order to facilitate the movement of hydrogen storage tanks, hydrogen storage tanks at this stage are often provided with lifting rings to facilitate the use of lifting machinery for lifting and loading hydrogen storage tanks. However, since hydrogen storage tanks are generally large in size, it is difficult to lift them using small lifting machinery, and large lifting machinery is difficult to work in a small space due to its size limitation. When it is necessary to move the hydrogen storage tanks over a short distance, it also faces the problem of high cost. Therefore, how to conveniently and quickly realize the short-distance movement of hydrogen storage tanks has become an urgent problem that needs to be solved. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the present invention provides a mobile organic liquid hydrogen storage tank, which has the advantages of being able to simply and quickly move the hydrogen storage tank without calling on external lifting machinery, thereby providing great convenience for the use of the hydrogen storage tank.

[0007] (II) Technical solution

[0008] To achieve the above object, the present invention provides the following technical solution: a mobile organic liquid hydrogen storage tank, comprising an outer box, a storage chamber is provided at the bottom of the outer box, a screw rod is rotatably connected in the storage chamber, a slider is threadedly connected to the screw rod, a connecting rod is rotatably connected to the bottom of the slider, a mounting plate is rotatably connected to the bottom end of the connecting rod, and casters are provided on the bottom surface of the mounting plate;

[0009] The ends of the outer box are rotatably connected to a fixing frame, the two sides of the fixing frame are rotatably connected to support rods, the middle part of the fixing frame is threadedly connected to a regulating rod, the outer end of the regulating rod is rotatably connected to a mounting column, the outer end of the support rod is rotatably connected to a protective plate having one end rotatably connected to the mounting column, and the protective plate is rotatably connected to a guide wheel;

[0010] A tank body is arranged inside the outer box, a restraining ring whose bottom end is fixedly connected to the outer box is arranged on the outer side of the tank body, an input pipe and an output pipe are respectively arranged at both ends of the tank body, a hydrogenation reaction assembly is fixedly connected to the end of the input pipe, and a dehydrogenation reaction assembly is fixedly connected to the end of the output pipe.

[0011] Preferably, the outer box adopts a rectangular structure, and there are a plurality of storage cavities which are evenly arranged at the lower part of the outer box.

[0012] Preferably, the screw rod is a bidirectional screw rod, a driving motor is provided at one end of the screw rod, and there are two sliders which are symmetrically arranged on the screw rod.

[0013] Preferably, the caster is an electric wheel, and a brake assembly is provided on the caster.

[0014] Adopting the above technical solution: the outer box provides installation space for components such as the tank body and can provide a certain degree of protection. The outer box adopts a rectangular structure, which is easier to fix on the transport vehicle than the tank body with a cylindrical structure, making the transportation of hydrogen energy more convenient. A storage cavity is opened at the bottom of the outer box to provide storage space for components such as the screw rod and casters, so as to facilitate the fixation of the device when the casters are not in use. The rotation of the screw rod drives the slider to move horizontally, and the slider pushes the connecting rod and the mounting plate to move vertically, so that the casters can be extended and retracted, which is convenient for adjusting the state of the outer box.

[0015] Preferably, the fixing frame is in a C-shaped structure as a whole and its two ends are rotatably connected to the outer box through a capstan, and the end of the support rod adopts an arc-shaped structure.

[0016] Preferably, the inner end of the regulating rod is fixedly connected with a rotating handle, and the outer side of the mounting column is also rotatably connected with a guide wheel.

[0017] The above technical solution is adopted: the fixed frame provides an installation platform for the support rod, the regulating rod and other structures, and is rotatably connected to the outer box through the capstan, so that when it is hit by a large external force, it can be deformed and rotate on the outer box to achieve force unloading, thereby reducing the damage to the outer box caused by the external force. The fixed frame has a C-shaped structure, so that it can be deformed after being hit to achieve the reduction of external force. The support rod is used to connect the protective plate, and the mounting column provides a mounting platform for the protective plate. The regulating rod is used to drive the mounting column to move horizontally in order to adjust the inclination angle of the protective plate.

[0018] Preferably, there are a plurality of guide wheels which are evenly arranged on the protective plate, and there are a plurality of restraining rings which are evenly arranged along the length direction of the tank body.

[0019] Preferably, an insulating water pipe network is arranged in the outer box, and an insulating cavity is opened in the outer box.

[0020] The above technical solution is adopted: when external force acts on the protective plate, the guide wheel rotates under the action of the external force, guiding the box body to turn as a whole, so that the impact force of the external force on the protective plate is reduced. When the external force is large, the protective plate is deformed, turned, or even damaged by the collision, so as to weaken the external force. The support rod and the fixed frame then bear the external force to provide protection for the outer box, so as to prevent the outer box from being damaged by collision during movement, affecting the normal operation of the hydrogen storage tank or even causing more serious safety accidents. An insulating water pipe network and an insulating cavity are set in the outer box. The insulating water pipe network uses the larger heat absorption ratio of water to absorb external heat, so as to prevent the external temperature from having a large impact on the temperature inside the outer box. The insulating cavity isolates the external heat again, providing suitable conditions for organic liquid hydrogen storage.

[0021] (III) Beneficial effects

[0022] Compared with the prior art, the present invention provides a mobile organic liquid hydrogen storage tank, which has the following beneficial effects:

[0023] 1. The mobile organic liquid hydrogen storage tank is provided with an outer box, a storage cavity, a screw, a slider, a connecting rod, a mounting plate, casters and other structures. When the hydrogen storage tank needs to be moved a short distance, the driving assembly drives the screw to rotate, the screw drives the slider to translate, the slider drives the mounting plate to move vertically through the connecting rod, the mounting plate drives the casters to move vertically to contact the ground and prop up the outer box, and then the outer box can be assisted to move. The hydrogen storage tank can be moved simply and quickly without calling an external lifting machine, which provides great convenience for the use of the hydrogen storage tank.

[0024] 2. The mobile organic liquid hydrogen storage tank is provided with a fixed frame, a support rod, a regulating rod, a mounting column, a protective plate, a guide wheel and other structures. When the hydrogen storage tank is moved, if it accidentally collides with an external object, the guide wheel rotates under the action of external force, guiding the entire box to turn, so that the impact force of the external force on the protective plate is reduced. When the external force is large, the protective plate is deformed, turned, or even destroyed by the collision, so as to weaken the external force. The support rod and the fixed frame then bear the external force to provide protection for the outer box, so as to prevent the outer box from being damaged by collision during movement, affecting the normal operation of the hydrogen storage tank or even causing more serious safety accidents.

[0025] 3. The mobile organic liquid hydrogen storage tank has an insulating water pipe network and an insulating cavity inside the outer box. The insulating water pipe network uses the larger heat absorption ratio of water to absorb external heat, thereby avoiding the external temperature from having a large impact on the temperature inside the outer box. The insulating cavity isolates the external heat again, thereby providing suitable conditions for organic liquid hydrogen storage. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] A tank body 14 is arranged inside the outer box 1, and a restraining ring 15 is arranged on the outer side of the tank body 14, and an input pipe 16 and an output pipe 17 are arranged at both ends of the tank body 14, and a hydrogenation reaction assembly 18 is fixedly connected to the end of the input pipe 16, and a dehydrogenation reaction assembly 19 is fixedly connected to the end of the output pipe 17.

[0036] Embodiment 1: The outer box 1 adopts a rectangular structure, and there are several storage chambers 2 that are evenly arranged at the bottom of the outer box 1. The screw rod 3 adopts a bidirectional screw rod, and a driving motor is provided at one end of the screw rod 3. There are two sliders 4 that are symmetrically arranged on the screw rod 3. The caster 7 adopts an electric wheel, and a brake assembly is provided on the caster 7. The outer box 1 provides installation space for components such as the tank body 14, and can provide a certain protection capability. The outer box 1 adopts a rectangular structure, which is easier to fix on a transport vehicle than the tank body 14 with a cylindrical structure, which makes the transportation of hydrogen energy more convenient. The storage chamber 2 is opened at the bottom of the outer box 1 to provide storage space for components such as the screw rod 3 and the caster 7, so as to facilitate the fixing of the device when the caster 7 is not in use. The rotation of the screw rod 3 drives the slider 4 to move horizontally, and the slider 4 pushes the connecting rod 5 and the mounting plate 6 to move vertically, so that the extension and contraction of the caster 7 can be realized, and the state of the outer box 1 can be adjusted conveniently.

[0037] Embodiment 2: The fixing frame 8 is an overall C-shaped structure and its two ends are rotatably connected to the outer box 1 through a capstan, and the end of the support rod 9 adopts an arc structure. The inner end of the regulating rod 10 is fixedly connected to a turning handle, and the outer side of the mounting column 11 is also rotatably connected to a guide wheel 13. The fixing frame 8 provides a mounting platform for the support rod 9, the regulating rod 10 and other structures. It is rotatably connected to the outer box 1 through a capstan, so that when it is hit by a large external force, it can be deformed and rotate on the outer box 1 to unload the force, thereby reducing the damage to the outer box 1 caused by the external force. The fixing frame 8 is a C-shaped structure, so that it can be deformed after being hit to reduce the external force. The support rod 9 is used to connect the protective plate 12, and the mounting column 11 provides a mounting platform for the protective plate 12. The regulating rod 10 is used to drive the mounting column 11 to move horizontally so as to adjust the inclination angle of the protective plate 12.

[0038] Embodiment 3: There are several guide wheels 13 evenly arranged on the protective plate 12, and there are several restraining rings 15 evenly arranged along the length direction of the tank body 14. An insulating water pipe network 20 is arranged in the outer box 1, and an insulating cavity 21 is opened in the outer box 1. When an external force acts on the protective plate 12, the guide wheel 13 rotates under the action of the external force, guiding the box body 1 to turn as a whole, so that the impact force of the external force on the protective plate 12 is reduced. When the external force is large, the protective plate 12 is deformed, turned, or even destroyed by the collision, so as to weaken the external force. The support rod 9 and the fixing frame 8 then bear the external force to provide protection for the outer box 1, so as to prevent the outer box 1 from being hit and damaged during movement, affecting the normal operation of the hydrogen storage tank or even causing more serious safety accidents. An insulating water pipe network 20 and an insulating cavity 21 are arranged in the outer box 1. The insulating water pipe network 20 utilizes the larger heat absorption ratio of water to absorb external heat, thereby preventing the external temperature from having a significant impact on the temperature inside the outer box 1. The insulating cavity 21 isolates the external heat again, thereby providing suitable conditions for organic liquid hydrogen storage.

[0039] When in use, hydrogen is added to the tank body 14 through the hydrogenation reaction assembly 18, and the tank body 14 is used to store organic liquid hydrogen. When the hydrogen storage tank needs to be transported, the outer box 1 can be directly fixed on the transport vehicle for transportation. When the hydrogen storage tank needs to be moved a short distance, the drive assembly drives the screw 3 to rotate, the screw 3 drives the slider 4 to translate, the slider 4 drives the mounting plate 6 to move vertically through the connecting rod 5, and the mounting plate 6 drives the caster 7 to move vertically to contact the ground and support the outer box 1, and then the outer box 1 can be assisted to move.
