[0024] Specifically, the solid hydrogen-based normal-temperature and normal-pressure hydrogen storage and transportation cycle equipment of the application comprises a solid hydrogen bottle 2, a hydrogen absorption module, a transportation device and a hydrogen storage module; wherein: the solid hydrogen bottle 2 is made of stainless steel and internally placed with a solid magnesium embryo 28; the hydrogen absorption module and the hydrogen storage module are both modular design structures and each comprises an intelligent heating device 1, which can heat the solid hydrogen bottle 2 to absorb hydrogen or release hydrogen; specifically, in this embodiment: the intelligent heating device 1 comprises a man-machine interaction module 11, an intelligent control module 12, a power module 13, a heating module 14, a nano heat preservation and insulation module 15, a temperature detection module 17 and a heat dissipation module 16; wherein: the man-machine interaction module 11 comprises a visual digital model and a touch screen, the visual digital model is used to display the running condition of the intelligent heating device, and the touch screen is used to control the intelligent heating device, which can adjust the running parameters of the device, such as the adjustment of heating temperature, pressure, heating sequence and the like, so as to realize the speed control of hydrogen absorption and release, thereby meeting the needs of customers; the intelligent control module 12 is the control center of the intelligent heating device 1 and electrically connected with the man-machine interaction module 11, the heating module 14, the temperature detection module 17 and the heat dissipation module 16, respectively, for realizing the automatic control of the intelligent heating device 1, which can self-adaptively maintain the heating temperature, timely compensate the heating temperature when the heating heat loss is too much due to the decrease of external environment temperature, and uniformly reduce the temperature in the furnace through the heat dissipation module 16 when a large amount of heat is released due to the violent reaction in the solid hydrogen bottle 2, so as to ensure that the temperature in the furnace is within a proper range. Meanwhile, the hydrogen pressure, the progress of hydrogen absorption and release, the emergency hydrogen release, the emergency temperature reduction and the like are monitored.

[0025] The power module 13 is electrically connected with the intelligent control module 12, the man-machine interaction module 11, the heating module 14, the temperature detection module 17 and the heat dissipation module 16, respectively; specifically, the power module 13 provides stable voltage and current for the intelligent heating device 1 through multiple groups of capacitors, so as to ensure the stability of heating; the heating module 14 is a module for converting electric energy into heat energy and comprises mica high-temperature copper wire and power supply wire; the mica high-temperature copper wire is wound outside the nano heat preservation and insulation module 15, and the power supply wire is connected with the mica high-temperature copper wire; when the mica high-temperature copper wire is electrified to generate a magnetic field, the magnetic field passes through the nano heat preservation and insulation module 15 and generates eddy current in the solid hydrogen bottle 2 made of stainless steel, so that the solid hydrogen bottle 2 starts to heat itself due to resistance, that is, the magnetic field generates eddy current in the solid hydrogen bottle 2 to form self-heating; at this time, the solid hydrogen bottle 2 made of stainless steel serves as a heating furnace to heat the solid magnesium embryo or solid hydrogenated magnesium in the bottle, so as to achieve the purpose of hydrogen absorption and release.

[0026] In order to improve the scope of application of the device, as an optional embodiment of the present application, the heating module 14 is arranged in a segmented structure along the vertical height direction, and each segment of the heating module 14 can be independently controlled to be suitable for solid block hydrogen cylinders 2 of different heights; that is, the wound mica high-temperature copper wire can be arranged in segments and multiple layers to meet solid block hydrogen cylinders of different heights or different pipe diameters.

[0027] In the present embodiment, the mica high-temperature copper wire has a copper core twisted by multiple strands of oxygen-free copper wires, a fluorine phlogopite layer in the middle layer, and an alkali-free glass fiber woven layer on the outside to meet the high-temperature fireproofing requirement.

[0029] It should be noted that the nano thermal insulation material in the present embodiment is a nano micropore material, and spherical polymer particles with a size of about 2-5 nanometers are combined into small units and then combined into a dendritic microstructure. These small units form a fractal chain-like three-dimensional structure filled with a large number of pores with a size of not more than 100 nanometers. These cavities can store air to block heat conduction, heat convection and heat radiation, thereby meeting the need for thermal insulation and heat loss reduction.

[0030] The temperature detection module 17 provides temperature detection data for the intelligent control module 12, is installed on the outside of the nano thermal insulation module 15, and is connected with the solid block hydrogen cylinder 2 through a spring probe to test the temperature of the solid block hydrogen cylinder 2 in real time; in order to improve the measurement accuracy, the temperature detection module 17 is installed at the upper, middle and lower parts of the nano thermal insulation module 15 in the present embodiment to correspond to different heights of the solid block hydrogen cylinder 2, and in the optimal embodiment, the height of the solid block hydrogen cylinder 2 is divided into upper, middle and lower parts, and the temperature detection module 17 is installed at the upper, middle and lower parts to increase the data collection reference and prevent a single probe from failing and causing control failure.

[0032] It should be noted that the pressurized air supply can include an air compressor or a blower, which is communicated with the air inlet holes 31 through a pipeline. Of course, since the number of air inlet holes 31 is multiple and arranged in a whole circle, an air duct 30 can be arranged along the whole circle on the outer wall of the heat insulation support; the pipeline is communicated with the air duct 30; the air duct 30 is communicated with each air inlet hole 31, and the pipeline is connected with the air compressor or the blower; the high-pressure cold air enters the air duct 30 through the pipeline, and then is blown into the space gap between the heat insulation support and the solid hydrogen cylinder 2 through each air inlet hole 31, and then is blown to the whole circle surface of the solid hydrogen cylinder 2; since the air inlet holes 31 are located at the lower part of the solid hydrogen cylinder 2, although the blown cold air is pressurized cold air, it can only be directly blown to the lower part of the solid hydrogen cylinder 2; in order to quickly remove heat, the air inlet holes 31 are arranged in an inclined structure, that is, the outlet axis of the air inlet holes 31 has an angle with the horizontal plane, which is inclined upward, and the center axis of the air inlet holes 31 is tangent to the outer wall of the solid hydrogen cylinder 2, so that the blown pressurized cold air can form a spiral-like airflow after being blown to the surface of the solid hydrogen cylinder 2, and flow upward, so as to contact the middle and upper surfaces of the solid hydrogen cylinder 2 by using the spiral airflow, thereby removing heat during the spiral rising process and achieving rapid cooling and heat dissipation.
