Compared with the prior art, the invention has the following beneficial effects:
the scheme provided by the patent successfully avoids the potential safety hazard of reaction of magnesium hydride and water in the original hydrogen generating device. In the original technical scheme, magnesium hydride and water are in exothermic reaction, and the reaction is more violent as the temperature is higher, so a cooling system is required to be added to control the temperature. If the temperature control fails, the reaction is uncontrollable, the temperature rises rapidly, after the boiling point of water is reached, the water in the hydrogen generating device is evaporated rapidly, the expansion can be more than 1600 times in a short time, the pressure in the cabin rises violently, and the risk of explosion exists; in the solution of the patent, the cooling system can be eliminated, the control logic and power output can be reduced (i.e. the absence of 9 cooling devices), and the risk of explosion can be avoided at the maximum reaction (boiling point of water in the device, theoretical maximum temperature, extreme point of reaction of magnesium hydride with water). Through the rapid water drainage function and a small amount of flowing water participating in the reaction, reactants are isolated, the reaction is effectively controlled, and the power density is far higher than that of the magnesium hydride hydrogen generation reaction at the control temperature, so that the core indexes of the hydrogen generation device, such as volume power density, mass power density, efficiency and the like, are realized.
The problem that the original hydrogen generating device is too big is stopped to the scheme success that this patent provided. In the original technical scheme, quantitative magnesium hydride is put into a reaction cabin and is subjected to continuous reaction through quantitative water injection, so that most of space in the cabin is used for storing water, and the volume density is low. After the reaction of one test is finished, the reaction product in the reaction cabin needs to be cleaned out and then replaced by new raw materials for continuous reaction, which is not beneficial to application in products; in this patent, magnesium hydride can be filled up basically in the reaction cabin body, and unnecessary water is directly taken out, does not occupy the space in reaction cabin, the utilization ratio in the space of great increase.
The scheme provided by the patent can effectively recover the reactants, and the reacted magnesium oxide and magnesium hydroxide are retained in the cabin through multiple filtration, then are collectively recovered and are repeatedly prepared into magnesium hydride for reuse.

The flowing water hydrogen fixation and generation device according to claim 9, wherein: the flowing water hydrogen fixation hydrogen generation device further comprises a control system, wherein the control system comprises a water pump, a one-way valve, a switch valve, a liquid level sensor, a temperature sensor, a pressure sensor and a control strategy, and the control strategy comprises the following steps:
the water pump is used for refluxing water in the condensed water tank to the relay water tank and is used for enabling the middle flow of the relay water tank to flow into the reaction cabin body and the drainage filter tank;
the one-way valves are arranged on the inlet and the outlet of each reaction cabin body, and are arranged on a return pipeline of the condensed water tank and pipelines of the relay water tank and the drain filter tank;
the liquid level sensor and the temperature sensor are arranged in the relay water tank;
the pressure sensor is arranged in each reaction cabin body;
the control strategy comprises
When an external load pulling load signal is detected, the solid hydrogen power supply system is started, the control system collects temperature information of the pressure sensor and processes the pressure information to judge whether the current reaction cabin needs to start to operate, the control system collects data of the temperature sensor and the liquid level sensor and judges whether the water quantity in the relay water tank is sufficient or not based on the data;
when the system judges that the reaction cabin body needs to be opened, the heating device is opened, and the water in the relay water tank is continuously heated; after the water temperature reaches the preset temperature, starting a water pump to inject flowing hot water into the reaction cabin;
obtaining temperature information in the reaction cabin body, stopping heating the relay water tank when the temperature exceeds a threshold value and the hydrogen generation speed is reduced, providing water with lower temperature, accelerating the hydrogen generation speed, and starting a heating device to provide hot water;
acquiring water level information in the relay water tank, and supplementing water through the condensed water tank;
stopping the water input into the reaction cabin and stopping the hydrogen generation.
