[0047] In the present application, when the user uses the device, when it is necessary to generate electricity by means of the mobile power supply body 1, the hydrogen in the hydrogen cylinder 14 is delivered to the inside of the hose 18, and the hydrogen is delivered to the anode of the fuel cell in the mobile power supply body 1 by means of the hose 18. Under the action of the platinum catalyst, oxidation reaction occurs, and the hydrogen is decomposed into positively charged protons and negatively charged electrons. The oxygen in the air is delivered to the cathode, and under the action of the catalyst, the protons migrate from the anode through the proton exchange membrane and the electrons flow from the external circuit to combine with the protons to generate water through reduction reaction. The silent reaction of hydrogen and oxygen under the action of the catalyst directly generates electric energy, and the only product is water, realizing zero-carbon, low-noise, and high-efficiency emergency power supply. Other devices that need to use electricity can be connected to the power socket 6 through the power cord plug to supply power to other external devices.

[0048] When the hydrogen in the hydrogen cylinder 14 is consumed and the old hydrogen cylinder 14 needs to be taken out from the inside of the mobile power supply body 1 and a new hydrogen cylinder 14 is installed in the mobile power supply body 1, as shown in Figure 13 two first electric telescopic rods 12 on the two sides of the control base 2 are controlled to extend at the same time, pushing the two mounting seats 11 to extend outward from the bottom end of the mobile power supply body 1, and the two rotating rods 39 are controlled to rotate upward by 90 degrees in the corresponding mounting seats 11 at the same time, driving the two drive plates 40 to rotate to the two sides of the mobile power supply body 1, respectively. The two second double-headed screws 42 are controlled to rotate at the same time, driving the moving blocks 43 connected by threads on the outer walls to move towards each other, thereby pushing the two drive plates 40 to move upward slowly. When the top ends of the two drive plates 40 abut against the bottoms of the two ends of the two rectangular slats 4, respectively, the two rectangular slats 4 and the cover plate 3 can be pushed to move upward at the same time as the two drive plates 40 continue to move upward. When the two second electric telescopic rods 45 are rotated to be vertical, the telescopic ends of the second electric telescopic rods 45 are controlled to extend upward, and the two rectangular slats 4 and the cover plate 3 are further pushed to move upward to a suitable height. At this time, the plurality of springs 26 are in a stretched state, and the cover plate 3 can be controlled to rotate downward by 180 degrees between the two rectangular slats 4, driving the two clamping plates 9 and other components to rotate to the position close to the mobile power supply body 1. The telescopic ends of the second electric telescopic rods 45 are slowly retracted, and the two second double-headed screws 42 drive the corresponding two moving blocks 43 to move away from each other to adjust, driving the two rectangular slats 4 and the cover plate 3 to slowly move downward at the same time.

[0049] In this process, the second slider 32 is controlled to move the second moving plate 31 and the two clamping plates 9 to the top of the hydrogen cylinder 14 inside the second sliding groove 30, until the cover plate 3 moves to the appropriate height, at which time the two clamping plates 9 move to the two sides of the hydrogen cylinder 14, and the first double-headed screw 34 drives the two moving seats 35 and the clamping plates 9 to move towards each other, conveniently driving the two clamping plates 9 and the corresponding soft pads 36 to tightly abut the outer wall of the hydrogen cylinder 14. Then, the two first sliders 29 are controlled to move inside the corresponding first sliding groove 7, driving the clamped and fixed hydrogen cylinder 14 to move inside the moving power supply body 1 away from the connector 17. The hydrogen cylinder 14 is connected with the connector 17, and the two second double-headed screws 42 are controlled to rotate together, driving the corresponding two moving blocks 43 to move towards each other. After the second electric telescopic rod 45 rotates to the vertical state, the second electric telescopic rod 45 is again stretched upwards to push the two rectangular strips 4, the cover plate 3, and the hydrogen cylinder 14 clamped and fixed by the two clamping plates 9 upwards, until the cover plate 3 moves to the appropriate height, and the cover plate 3 is controlled to rotate between the two rectangular strips 4 and reset, driving the clamped and fixed hydrogen cylinder 14 to flip upwards to the top of the cover plate 3. Then, the staff can remove the old hydrogen cylinder 14 from between the two clamping plates 9 and place the new hydrogen cylinder 14 between the two clamping plates 9 for clamping and fixing.

[0050] The cover plate 3 drives the new hydrogen cylinder 14 to flip 180 degrees, and the above steps of the cover plate 3 driving the two clamping plates 9 to flip downwards and move into the moving power supply body 1 are repeated, driving the new hydrogen cylinder 14 to enter the moving power supply body 1 and be placed on the top of the two placing racks 16. Then, the two first sliders 29 move inside the corresponding first sliding groove 7, conveniently driving the first moving plate 8 to move towards the connector 17. The new hydrogen cylinder 14 can be connected and fixed with the connector 17. Finally, the cover plate 3 drives the two clamping plates 9 to flip upwards, and the two second double-headed screws 42 and the second electric telescopic rod 45 are controlled to move back to their original positions. The old hydrogen cylinder 14 is automatically disassembled and the new hydrogen cylinder 14 is automatically installed, without the need for manual disassembly and assembly of the hydrogen cylinder 14, reducing the risk of manual disassembly and assembly.

[0051] The two housings 37 are each provided with a weighing sensor 38, which can detect the weight of the old hydrogen cylinder 14 in real time after the old hydrogen cylinder 14 is removed, ensuring that the hydrogen in the old hydrogen cylinder 14 is consumed, facilitating subsequent processing of the old hydrogen cylinder 14 by the staff, and avoiding the problem of safety hazards during the processing of the old hydrogen cylinder 14 when there is still some hydrogen left in the old hydrogen cylinder 14.

[0052] And after the new hydrogen cylinder 14 is placed between the two clamping plates 9 and clamped and fixed, the weight of the new hydrogen cylinder 14 can also be detected in real time by means of the two weighing sensors 38 at this time, so as to detect the hydrogen volume inside the new hydrogen cylinder 14. The relevant staff can infer how much electric energy can be generated subsequently according to the hydrogen volume inside the hydrogen cylinder 14, thereby bringing convenience for people to use the mobile power supply body 1 subsequently.

[0053] Because the waterproof and breathable film 15 is arranged inside the mobile power supply body 1 and can be stretched and contracted, it can cooperate with the two heat dissipation nets 5, so that when the mobile power supply body 1 is used in a humid environment, the waterproof performance of the mobile power supply body 1 is improved, and it is ensured that the mobile power supply body 1 can be normally used in a humid environment.

[0054] When the internal temperature of the mobile power supply body 1 is high during use, the two first electromagnets 27 at the bottom of the cover plate 3 can be controlled to be powered on and started, so as to be magnetically attracted and fixed with the metal frame 22. The above-mentioned step of pushing the two rectangular strips 4 and the cover plate 3 upward by means of the driving mechanism is repeated, and after the cover plate 3 moves upward to a specified height, the heat inside the mobile power supply body 1 can be quickly volatilized and discharged outward, so as to improve the heat dissipation efficiency inside the mobile power supply body 1. After the cover plate 3 moves upward, the metal frame 22 can be driven to move upward synchronously, and the waterproof and breathable film 15 is pulled to expand upward together, so as to block the top opening of the mobile power supply body 1. While not affecting the heat dissipation efficiency inside the mobile power supply body 1, foreign matters can be prevented from entering the inside of the mobile power supply body 1, and the protection effect of the internal components of the mobile power supply body 1 is improved.

[0055] After the two heat dissipation nets 5 are used for a period of time, impurities will inevitably be attached to the surface of the heat dissipation net 5. In order to avoid the impurities attached to the surface of the heat dissipation net 5 from affecting the heat dissipation effect of the mobile power supply body 1 during normal use, when impurities are found on the surface of the two heat dissipation nets 5, Figure 13As shown, the above-mentioned two driving plates 40 are elongated upward by the driving mechanism, and the two rectangular strips 4 are pushed upward, so that the two blocking plates 10 are pushed upward and rotated to the vertical state at the same time, and the two heat dissipation nets 5 are blocked, and after the two blocking plates 10 are rotated to the vertical state, the top ends of the two blocking plates 10 abut against the bottom end of the cover plate 3, and the two blocking plates 10 are magnetically attracted to the corresponding second electromagnet 28, and during the process that the two driving plates 40 of the driving mechanism push the two rectangular strips 4 and the cover plate 3 to move up and down on the top of the mobile power supply body 1, the two blocking plates 10 and the corresponding two sliding blocks 23 can be synchronously moved up and down, so that the first soft brush 25 arranged on the two blocking plates 10 can automatically clean and remove the impurities attached to the surface of the two heat dissipation nets 5 during the friction contact with the corresponding heat dissipation net 5, so as to ensure the normal use of the two heat dissipation nets 5 without being affected by the impurities.

[0056] At the same time, since the second soft brush 47 is arranged on one side of the two driving plates 40, when it is necessary to clean the power sockets 6 on the two sides of the mobile power supply body 1, the driving device inside the mobile power supply body 1 is controlled to drive the base 2 to rotate by 90 degrees, so that the two driving plates 40 of the driving mechanism are rotated to be close to the lower side of the two groups of power sockets 6, the two mounting seats 11 and the rotating rod 39 are pushed out from the bottom of the mobile power supply body 1 by the extension of the extension ends of the two groups of first electric telescopic rods 12, and after the two rotating rods 39 are controlled to rotate upward by 90 degrees in the corresponding mounting seat 11, the two driving plates 40 are moved upward on the two sides of the mobile power supply body 1 by driving the two second double-headed screws 42 to continue to rotate, so that the two second soft brushes 47 are brought into friction contact with the two groups of power sockets 6 on the two sides of the mobile power supply body 1, and the impurities attached to the surfaces of the two groups of power sockets 6 are automatically cleaned, facilitating the subsequent use of the two groups of power sockets 6.

[0057] Since the driving mechanism is arranged below the mobile power supply body 1, when the mobile power supply body 1 is used in a mountainous area with rugged ground, the mobile power supply body 1 cannot be stably placed on the ground, at this time, the mobile power supply body 1 can be placed between two trees, as shown in Figure 1 and Figure 2 As shown, by directly controlling the rotation of the two second double-headed screws 42, the two driving plates 40 are moved away from the mobile power supply body 1, until the side walls of the two driving plates 40 far away from each other abut against the surfaces of the corresponding trees, so that the mobile power supply body 1 can be clamped and fixed between the two trees by the driving mechanism, and the mobile power supply body 1 can be stably used.

[0058] Meanwhile, in the process of using the mobile power supply body 1 outdoors, if it rains outside, in order to avoid rainwater accumulating at the bottom of the mobile power supply body 1, at this time, the two rotating rods 39 can be controlled to rotate downward by 90 degrees inside the corresponding mounting seats 11, driving the two drive plates 40 to rotate to the top of the mobile power supply body 1, at this time, the drive mechanism drives the two drive plates 40 to move away from the rotating rods 39, so that the drive mechanism can be used as a lifting mechanism at this time, placing the two drive plates 40 on the ground, ensuring that the distance between the mobile power supply body 1 and the ground increases, cooperating with the telescopic adjustment of the telescopic ends of the two groups of first electric telescopic rods 12, driving the two drive plates 40 to synchronously adjust the support area of the mobile power supply body 1, and finally placing stones and other heavy objects on the top of the two drive plates 40 to assist in pressing and fixing the mobile power supply body 1, so that the mobile power supply body 1 can be normally used in the environment with accumulated water on the ground.

[0059] If the mobile power supply body 1 is damaged during use, causing hydrogen to escape outward, in order to avoid the escaped hydrogen from causing harm to the surrounding workers, the above-mentioned step of pushing the two blocking plates 10 upward to block the heat dissipation nets 5 by means of the drive mechanism can be repeated, so that after the two blocking plates 10 are rotated upward to be vertical, the heat dissipation nets 5 can be effectively blocked, and the state of the two drive plates 40 abutting against the outer walls of the two blocking plates 10 is maintained, by means of the contraction of the telescopic ends of the two groups of first electric telescopic rods 12, the two drive plates 40 are moved toward each other, so as to have a pushing and extruding effect on the two blocking plates 10, ensuring that the rubber rings 24 provided on the two blocking plates 10 can tightly abut against the outer wall of the mobile power supply body 1, improving the blocking effect of the two heat dissipation nets 5, facilitating the workers to quickly transfer the mobile power supply body 1 to an open outdoor environment, avoiding the continuous escape of hydrogen outward through the two heat dissipation nets 5, and improving the protection effect on the surrounding workers.
