Description

Technical Field

[0001] The present invention relates to the technical field of organic liquid hydrogen storage tanks, and particularly to a mobile leg structure for an organic liquid hydrogen storage tank. Background Art

[0002] The principle of liquid organic hydrogen storage technology (abbreviated as LOHC) is to achieve hydrogen storage (chemical bonding) by means of the reversible reaction and hydrogenation reaction between certain unsaturated liquid organic compounds such as olefins, alkynes or aromatic hydrocarbons and hydrogen, and to achieve hydrogen release by means of dehydrogenation reaction. The mass hydrogen storage density is 5%-10%, the hydrogen storage capacity is large, and the hydrogen storage material is a liquid organic compound, which can be transported at normal temperature and pressure, and is convenient and safe. In principle, each unsaturated compound (organic molecule with carbon-carbon double bond or triple bond) can absorb hydrogen during the hydrogenation process. The organic liquid hydrogen storage technology realizes hydrogenation and dehydrogenation by means of the reversible reaction between certain hydrogen storage agents such as olefins, alkynes or aromatic hydrocarbons and hydrogen. In LOHC, hydrogen chemical bonds are combined with organic hydrocarbon carrier molecules (hydrogenation) and can be released in the reverse process (dehydrogenation).

[0003] When liquid organic compounds are in progress, they need to be loaded into a closed tank body, and external hydrogenation reactors and dehydrogenation reactors are used to realize hydrogen storage and release. The tank body for hydrogen storage needs to be installed on an external vehicle frame to transport the tank body by a semi-trailer. However, traditional organic hydrogen storage tanks are generally directly fixed on the vehicle frame. After the tank body is transported to the gas filling station, the tank body and the vehicle body need to be docked synchronously, which leads to the occupation of the vehicle body, reduces the use efficiency of the vehicle body, and increases the cost input at the same time. Based on this, a mobile leg structure for an organic liquid hydrogen storage tank is proposed. By installing a mobile leg mechanism at both ends of the tank body, the tank body can be lifted, and the wheels arranged at the bottom of the mobile mechanism enable the tank body to approach or move away from the vehicle body for overall loading and unloading.

[0033] Please refer to Figure 1-8 , a moving leg structure for an organic liquid hydrogen storage tank, which includes a support beam 1. The bottom surface of the support beam 1 is fixedly connected with a bottom plate 2, and its top end is provided with an outer shell 3;

The two ends of the two restraint belts 12 are fixedly connected with the two ends of the fixed seat 14. A rubber belt 13 is arranged between the two restraint belts 12 and the tank body 11;

[0035] On both sides of the top surface of the support beam 1, mounting seats 4 are fixedly connected. On both sides of the two mounting seats 4, first placement grooves 15 are provided. At the bottom ends of the two mounting seats 4, second placement grooves 18 are provided. Inside the two second placement grooves 18, two support legs 5 that move along their length directions are provided.

At the bottom ends of the four rotating seats 17, multi-stage hydraulic cylinders 8 are fixedly connected;

[0036] The output ends of the four multi-stage hydraulic cylinders 8 are all fixedly connected with mounting frames 22. The four mounting frames 22 are of a hollow structure, and the bottom surfaces of the inner walls of all of them are fixedly connected with first motors 23. The output ends of the four first motors 23 are all fixedly connected with rotating seats 24. On both sides of the four rotating seats 24, electric vehicle wheels 7 are rotatably connected.

[0037] As an alternative technical solution of the present invention:

[0038] The bottom plate 2 is fixedly connected to the bottom surface of the support beam 1 by welding, which is convenient for a stable connection with the support beam 1 and simultaneously protects the bottom surface of the support beam 1.

[0039] As an alternative technical solution of the present invention:

[0040] The bottom end of the outer shell 3 is fixedly connected to the edge of the top surface of the bottom plate 2 by welding, which is convenient for combining the outer shell 3 and the bottom plate 2 into a relatively enclosed space, facilitating the protection of the tank body 11. At the same time, in order to provide an installation and heat dissipation position for the remaining reactors conveniently, a number of louver holes need to be opened on the outside of the outer shell 3 to facilitate communication with the outside air.

[0041] As an alternative technical solution of the present invention:

[0042] The bottom surfaces of the two fixed seats 4 are both fixedly connected to the support beam 1 by welding. The two sides of the two fixed seats 4 are respectively flush with the two side surfaces of the outer shell 3, so that one side of the two fixed seats 4 close to the first placement groove 15 is convenient for connection with the outside air, and the four multi-stage hydraulic cylinders 8 can enter the inside of the first placement groove 15.

[0043] As an alternative technical solution of the present invention:

[0044] On the mutually away side surfaces of the two fixed seats 4, second motors 10 are fixedly connected. The output ends of the four second motors 10 are all fixedly connected with gears 19. The middle parts of the top surfaces of the four support legs 5 are recessed downward, and racks 9 are fixedly connected inside all of them.

[0045] As an alternative technical solution of the present invention:

The bottoms of the four support legs 5 close to the inner wall of the rotating base 17 are fixedly connected with third motors 20, and the output ends of all four are fixedly connected with first bevel gears 21. The outer walls of the four rotating bases 17 are fixedly connected with second bevel gears 16, which are respectively meshed with the four first bevel gears 21, facilitating the rotation of the rotating base 17 by 180 degrees through the energized operation of the four third motors 20, and driving the multiple electric vehicle wheels 7 to rotate through the energized operation of the four first motors 23, so that the sides of the electric vehicle wheels 7 are flush with the first placement grooves 15.

[0047] As an alternative technical solution of the present invention:

[0048] Both sides of the four rotating bases 17 are respectively rotatably connected to one ends of the four support legs 5 through pins. The bottoms of the four rotating bases 17 are fixedly connected with protective covers 6. The four protective covers 6 are respectively located on the outer walls of the four multi-stage hydraulic cylinders 8. The protective covers 6 facilitate the protection of the multi-stage hydraulic cylinders 8, avoiding direct impact between external foreign objects and the multi-stage hydraulic cylinders 8.

[0049] As an alternative technical solution of the present invention:

[0050] The distance between the mutually remote sides of the eight electric vehicle wheels 7 is less than the width of the four first placement grooves 15, facilitating the smooth entry of the eight electric vehicle wheels 7 into the interiors of the four first placement grooves 15 and reducing space occupation.

[0051] When the organic liquid hydrogen storage tank moving support leg structure is in use, it includes the following steps:

[0052] 1) The four multi-stage hydraulic cylinders 8 all perform an extending action, making the multiple electric vehicle wheels 7 contact the ground, lifting the support beam 1 and the tank body 11 as a whole, and separating them from the external vehicle body;

[0053] 2) The multiple electric vehicle wheels 7 are energized to operate, driving the tank body 11 to move;

[0054] 3) The four first motors 23 are energized to operate, driving the multiple electric vehicle wheels 7 to rotate synchronously by a certain angle to adjust the moving direction of the tank body 1;

[0055] 4) After the transfer is completed, the four multi-stage hydraulic cylinders 8 synchronously perform a shortening action, making the bottom plate 2 stably contact the ground, and at the same time making the multiple electric vehicle wheels 7 away from the ground;

[0056] 5) The four third motors 20 are energized to operate, driving the rotating seat 17 to rotate 180 degrees. By energizing and operating the four first motors 23, the multiple electric vehicle wheels 7 are driven to rotate, making the side surfaces of the electric vehicle wheels 7 flush with the first placement groove 15;

[0057] 6) Gear 19 is fixedly connected to the output end of each of the four second motors 10, and the four gears respectively mesh with the four racks 9. The four second motors 10 are energized to operate, causing the four support legs 5 and the electric vehicle wheels 7 to enter the interior of the first placement groove 15.

[0058] All the electrical components mentioned in this article are electrically connected to an external main controller and 220V mains power supply, and the main controller can be a conventional known device such as a computer that plays a control role.

[0059] During unloading, the four multi-stage hydraulic cylinders 8 all extend, causing the multiple electric vehicle wheels 7 to contact the ground, lifting the support beam 1 and the tank body 11 as a whole and disengaging them from the external vehicle body. The multiple electric vehicle wheels 7 are energized to operate, driving the tank body 11 to move. Subsequently, the four first motors 23 are energized to operate, driving the multiple electric vehicle wheels 7 to rotate synchronously by a certain angle, facilitating rotation in different directions to adjust the moving direction of the tank body 1. After the transfer is completed, the four multi-stage hydraulic cylinders 8 contract synchronously, stably placing the bottom plate 2 on the ground, and at the same time moving the multiple electric vehicle wheels 7 away from the ground. Subsequently, the four third motors 20 are energized to operate, driving the rotating seat 17 to rotate 180 degrees, making the four multi-stage hydraulic cylinders 8 in a vertical state. By energizing and operating the four first motors 23, the multiple electric vehicle wheels 7 are driven to rotate, making the side surfaces of the electric vehicle wheels 7 flush with the first placement groove 15. Finally, by energizing and operating the four second motors 10, the four support legs 5 and the electric vehicle wheels 7 enter the interior of the first placement groove 15.

[0060] In summary, for the mobile support leg structure of the organic liquid hydrogen storage tank, with the support beam 1 as the main body, the bottom plate 2 and the outer shell 3 are added, thus facilitating the formation of a protective barrier outside the tank body 11. By setting four support legs 5, and multi-stage hydraulic cylinders 8 are provided at the ends of the four legs away from each other. Electric vehicle wheels 7 are rotatably connected to the outside of the rotating seats 24 on both sides of the output ends of the four first motors 23. Therefore, during use, when the four multi-stage hydraulic cylinders 8 all extend, it is convenient to lift the support beam 1 and the tank body 11 as a whole and separate them from the external vehicle body. By energizing and operating the multiple electric vehicle wheels 7, the tank body 11 can be transferred away from the external vehicle body. The overall structure is simple, the design is reasonable, and the practicability is high, which is convenient for popularization and use. By setting four third motors 20, the output ends of the four motors are fixedly connected with first bevel gears 21, which are respectively engaged with the second bevel gears 16 on the outer walls of the four rotating seats 17. By energizing and operating the four third motors 20, the rotating seats 17 are driven to rotate 180 degrees. By energizing and operating the four first motors 23, the multiple electric vehicle wheels 7 are driven to rotate, making the sides of the electric vehicle wheels 7 flush with the first placement grooves 15. By fixedly connecting gears 19 to the output ends of the four second motors 10, and the four gears are respectively engaged with the four racks 9. Therefore, when the four second motors 10 are energized and operated, the four support legs 5 and the electric vehicle wheels 7 can enter the inside of the first placement grooves 15, reducing the space occupation. The overall structure is simple and convenient for pushing and using.
