[0001] The invention relates to the technical field of hydrogen storage tanks, and in particular to a hydrogen storage tank filled with hydrogen adsorption material. Background Art

[0002] As hydrogen energy becomes increasingly prominent in the energy field, safe and efficient hydrogen storage technology has become a research hotspot. Traditional high-pressure gaseous hydrogen storage and liquid hydrogen storage methods have many limitations. For example, high-pressure gaseous hydrogen storage requires high-pressure containers and has a relatively low hydrogen storage density. Liquid hydrogen storage faces problems such as high energy consumption for low-temperature liquefaction and harsh storage conditions. The hydrogen storage method based on hydrogen adsorption materials has the advantages of relatively low hydrogen storage pressure, good safety, and potential for increased hydrogen storage density.

[0003] Based on the above, the inventors have found the following problems: when using existing hydrogen storage tanks filled with hydrogen adsorption materials, most of them use heat exchange tubes wrapped around the outside of the tank to adjust the temperature of the tank. However, due to the thick wall thickness of the tank, the heat transfer resistance is large, which affects user use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a hydrogen storage tank filled with hydrogen adsorption material is provided, in order to achieve the purpose of having more practical value. Summary of the invention

[0006] In view of the above problems, the technical solution proposed by the present invention is: A hydrogen storage tank filled with hydrogen adsorption material comprises a tank body, a tank cover is installed at one end of the tank body, a heat exchange tube is arranged inside the tank body, both ends of the heat exchange tube pass through the other end of the tank body, the heat exchange tube is in a "U" shape, a plurality of heat dissipation fins are installed on the outside of the heat exchange tube, hydrogen storage material is arranged between the plurality of heat dissipation fins, support seats are installed on both sides of the bottom end of the tank body, a bottom box is installed at the bottom end of the support seat, a limiting mechanism is arranged inside the bottom box, universal wheels are installed on both sides of the bottom end of the bottom box, one end face of the tank cover is connected with a gas inlet and outlet pipe, a valve is installed at one end of the gas inlet and outlet pipe, and an inlet and outlet gas connecting pipe is installed at one end of the valve.

[0007] Furthermore, the limiting mechanism includes a bidirectional threaded rod, both ends of the bidirectional threaded rod are rotatably connected to the inner side of the bottom box, a motor is installed on one end surface of the bottom box, the output end of the motor is connected to one end of the bidirectional threaded rod, both ends of the bidirectional threaded rod are equipped with movable blocks, the bottom end of the movable block is hinged with a connecting rod, one end of the connecting rod is hinged with a connecting block, and a limiting plate is installed on the bottom end of the connecting block.

[0013] Furthermore, a control panel is installed on one side of the top end of one of the bottom boxes, and the control panel is electrically connected to the motor through a wire.

[0014] In another aspect, the present invention provides a method for using a hydrogen storage tank filled with hydrogen adsorbent material, comprising the following steps: S1, equipment fixing: First, move the hydrogen storage tank to the predetermined use position through the universal wheel at the bottom, start the motor through the control panel, and the motor drives the bidirectional threaded rod to rotate, so that the movable block moves, so that the limit plate moves downward under the guidance of the sliding rod and the sliding sleeve until the rubber pad is in close contact with the ground, and then rely on the anti-slip texture of the rubber pad to stably fix the hydrogen storage tank in the current position to prevent it from displacement during use; S2, Hydrogen storage: Make sure the valve is closed, connect the hydrogen source to the gas inlet and outlet pipes, and then slowly open the valve.

The output end of the motor is connected to one end of the two-way threaded rod to realize the electric rotation of the two-way threaded rod. Both ends of the two-way threaded rod are equipped with movable blocks. The two-way threaded rod can be rotated to drive the movable block to move, so that the connecting rod and the connecting block drive the limit plate to rise and fall.

The heat exchange medium flows in the "U"-shaped heat exchange tube (108), and exchanges heat with the environment in the tank body (100) through the heat dissipation fins (113) on the outside of the heat exchange tube (108). The heat dissipation fins (113) are evenly spaced and have a plurality of vents on one side, which is conducive to uniform heat transfer and dissipation, thereby achieving the adjustment of the temperature in the tank body (100) to optimize the adsorption and desorption performance of the hydrogen storage material (114) on hydrogen; S4, mobile transportation: If the hydrogen storage tank is to be moved to another location, firstly, the motor (11210) is started to rotate in reverse through the control panel (115), so that the bidirectional threaded rod (11201) drives the movable block (11202) to move in the opposite direction, thereby retracting the limit plate (11205) upward, and then the hydrogen storage tank can be conveniently moved to a new location through the universal wheel (111).
