Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0026] As Figures 1 to 4As shown in the figure, this embodiment first discloses the hydrogen production component of the present utility model. The technical solution adopted is as follows: it includes a reaction chamber 1, which is a cylindrical structure with an open top surface. There is a hydrogen outlet 101 on its side wall. There is an external thread on the outside of the reaction chamber 1 at the opening of the reaction chamber 1. A reaction unit is installed inside the reaction chamber 1. The reaction unit further includes a chamber cover 2, a material box 3, and a water storage box 4. The chamber cover 2 has an internal thread that matches the external thread of the reaction chamber 1. Both the material box 3 and the water storage box 4 are cylindrical structures with open top surfaces. The material box 3 contains a powdered solid hydrolysis hydrogen production material, and the water storage box 4 contains water for the reaction. The bottom of the water storage box 4 is a connecting seat 401. The port of the material box 3 and the connecting seat 401 are connected by threads. There is a plugging hole 402 on the top surface of the connecting seat 401. The bottom surface of the plugging hole 402 is connected to the inside of the lower material box 3 through a threaded pipe. A connecting rod 201 is coaxially connected to the inner top surface of the chamber cover 2. The lower section of the connecting rod 201 is a threaded section, and the threaded section meshes with the threaded pipe opened on the connecting seat 401. Moreover, the thread direction between the threaded section and the threaded pipe is opposite to the thread direction between the chamber cover 2 and the reaction chamber 1. In order to further isolate the water storage box 4 and the material box 3, a plug 5 is connected to the smooth rod end of the connecting rod 201 through a spring buckle. The plug 5 slides and contacts inside the plugging hole 402 and can plug the plugging hole 402. In order to prevent the gas generated during the reaction from taking out a large amount of the water in the water storage box 4 that has not entered the material box 3, a water baffle 6 is also connected to the smooth section of the connecting rod 201 through a spring buckle. The water baffle 6 is in the shape of a bamboo hat and is located above the plug 5. In order to ensure that the generated gas can be discharged, the outer diameter of the water baffle 6 is smaller than the inner diameter of the water storage box 4. There is a hydrogen outlet 101 on the side wall of the reaction chamber 1. In order to prevent water leakage, a sealing ring is installed between the opening end face of the water storage box 4 and the chamber cover 2.

[0027] In order to be able to open the plug 5, a longitudinal guiding groove is opened on the inner side wall of the reaction chamber 1, and a longitudinal guiding block is provided on the outer wall of the water storage box 4. When the reaction unit is installed in the reaction chamber 1, the guiding block enters the guiding groove, so that through the limitation of the guiding block by the guiding groove, the chamber cover 2 can rotate relative to the water storage box 4.

[0028] In order to be able to completely open the plugging hole 402, the depth of the reaction chamber 1 is greater than the sum of the heights of the material box 3 and the water storage box 4. The thread length between the reaction chamber 1 and the chamber cover 2 is greater than the length of the threaded section of the connecting rod 201. When the chamber cover 2 is screwed, the connecting seat 401 can be separated from the connecting rod 201, and the material box 3 and the water storage box 4 fall to the bottom of the reaction chamber 1 under the action of gravity, so that the plug 5 is completely separated from the plugging hole 402, and the plugging hole 402 is completely opened.

[0029] In order to facilitate the injection of water into the water storage box 4, a water injection port 202 is opened on the top surface of the chamber cover 2. The water injection port 202 penetrates up and down and is opposite to the inside of the water storage box 4. There is a water plug on the water injection port 202 for plugging the water injection port 202 when no water is injected.

[0030] This embodiment also discloses a hydrogen energy power supply based on the above hydrogen production component, such as Figures 5 to 8 shown, which includes a square main housing 7. The side of the main housing 7 is open for easy installation of internal components. A cover plate 18 is installed at the opening. The reaction chamber 1 of the hydrogen production component is vertically installed in the main housing 7. In order to dry the generated hydrogen, a drying shell 16 is also installed in the main housing 7. A drying tube 11 is connected in the drying shell 16 by threads. Activated carbon is filled in the drying tube 11. A first air outlet for the dried hydrogen to overflow is opened on the drying tube 11. In order to prevent hydrogen from overflowing, an O-ring is installed between the drying tube 11 and the drying shell 16. In order to convert hydrogen into electric energy, a fuel cell 12 is installed in the main housing 7 through a fixing frame. The hydrogen outlet 101 of the hydrogen production component is connected to the first air inlet of the drying tube 11 through a pipeline, and the second air outlet of the drying shell 16 is connected to the second air inlet of the fuel cell 12 through a pipeline.

[0031] In order to stably distribute the electric energy generated by the fuel cell 12, a controller 13 and a lithium battery 14 are installed in the main housing 7. The controller 13 adopts an MPPT controller and is electrically connected to the fuel cell 12 and the lithium battery 14. When the electric energy output by the fuel cell 12 is sufficient, the controller 13 can store the excess electricity in the lithium battery 14, and can also use the electricity stored in the lithium battery 14 for supplement when the output voltage of the fuel cell 12 is low.

[0032] In order to meet the needs of disaster relief, a strobe light 8 and a buzzer 9 are installed on the main housing 7 as loads, and a key switch 10 is installed to facilitate informing the rescue command center of its own location. A positioning module 15 is also installed in the main housing 7. The positioning module 15 adopts a GPS module. The strobe light 8, the buzzer 9, the key switch 10, and the positioning module 15 are all electrically connected to the controller 13.

[0033] The working principle of the present utility model:

[0034] During preparation, the solid hydrolysis hydrogen production material is taken out of the package and loaded into the material box 3. The material box 3 is connected to the water storage box 4. After a sealing ring is padded at the port of the water storage box 4, the connecting rod 201 of the bin cover 2 is screwed into and tightened against the threaded tube of the connecting seat 401 to press the bin cover 2 against the sealing ring. At this time, the sealing plug 5 enters the sealing hole 402 to seal the sealing hole 402. The water injection port 202 is opened, water is injected into the water storage box 4, and after completion, the water injection port 202 is blocked. The drying tube 11 is filled with activated carbon.

[0035] In use, the drying tube 11 is installed in the drying shell 16, and the first air inlet of the drying tube 11 is connected to the hydrogen outlet 101 of the reaction chamber 1 through a pipeline. The reaction unit is installed in the reaction chamber 1. When installing, the orientation block enters the orientation groove. Then, the chamber cover 2 is screwed. Due to the positioning of the orientation block and the orientation groove, the chamber cover 2 rotates relative to the water storage box 4. Due to the reverse threads, during the process that the chamber cover 2 gradually engages tightly with the reaction chamber 1, the threaded section of the connecting rod 201 pushes the water storage box 4 and the material box 3 downward, so that the sealing plug 5 gradually separates from the sealing hole 402. Since the thread length between the reaction chamber 1 and the chamber cover 2 is greater than the length of the threaded section of the connecting rod 201, during the screwing process, the connecting seat 401 will fall off from the threaded section of the connecting rod 201. Subsequently, the water storage box 4 and the material box 3 drop to the bottom surface of the reaction chamber 1, and the sealing hole 402 is completely opened. The water in the water storage box 4 enters the material box 3 through the sealing hole 402 and the threaded pipe, contacts the solid hydrolysis hydrogen production material, reacts to generate hydrogen. During the process that hydrogen carries water vapor upward, most of the water vapor carried by it will be blocked by the water baffle 6. Hydrogen carrying a small amount of water vapor enters the drying tube 11 through the hydrogen outlet 101, contacts the activated carbon. After the activated carbon adsorbs the water vapor carried in the hydrogen, the dried hydrogen overflows through the first air outlet into the drying shell 16, and then enters the fuel cell 12 through the second air outlet to generate electricity. The controller 13 stores the generated electric energy into the lithium battery 14.

[0036] When the key switch 10 is turned on, the controller 13 supplies the electric energy generated by the fuel cell 12 and the electric energy stored in the lithium battery 14 to make the flashing lamp 8, the buzzer 9 and the positioning module 15 work. The indicator lamp 17 can indicate the power generation situation of the fuel cell 12, so as to know the remaining situation of the solid hydrolysis hydrogen production material in the reaction unit.

[0037] The circuit and mechanical connections involved in the present utility model are conventional means adopted by those skilled in the art, and technical inspiration can be obtained through limited experiments, which belong to common general knowledge.

[0038] The components not described in detail in this article are prior arts.

[0039] The water baffle in the present utility model can also be replaced with other common water blocking structural parts such as a demister, a mesh plate, etc.

[0040] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
