[0020] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0021] Example 1:

[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, a negative pressure formation sealed hydrogen absorption device includes: a base 1, a pad 11 is fixedly installed on the bottom of the base 1 by bolts, and positioning grooves are opened on the four sides of the bottom of the pad 11. The pad 11 and the positioning grooves under the pad 11 can further improve the stability of the base 1 when it is placed on the ground, a support frame 12 is fixedly installed on both ends of the top of the base 1 by bolts, and the support frame 12 is a plate structure, and a support platform 13 is fixedly installed on one side of the support frame 12 by bolts, and the support platform 13 is an L-shaped plate structure; it also includes: a delivery pipe 2, plugged into the middle of the two support frames 12, the delivery pipe 2 is a steel structure, the tops of the two support platforms 13 are respectively fixedly connected to the two ends of the delivery pipe 2 by bolts, so as to implement the positioning of the delivery pipe 2, and a plurality of parallel electric push rods 21 are fixedly installed by bolts below the outer periphery of the delivery pipe 2 between the two support frames 12, the output end of the electric push rod 21 faces downward, and the power output end of the electric push rod 21 is fixedly installed with a mounting block 22 by bolts, and an air suction head 23 is fixedly installed at one end below the mounting block 22 by bolts, and the air suction head 2 3 is installed inside, and the one-way valve can prevent the extracted hydrogen from flowing back, thereby further improving the efficiency of hydrogen extraction. An elastic air tube 24 is fixed between the mounting block 22 and the delivery pipe 2 by bolts. The middle part of the elastic air tube 24 is bent to form an elastic buffer part 25. The elastic buffer part 25 is a spiral structure. The elastic buffer part 25 can further improve the stability of the elastic air tube 24 when stretched, thereby facilitating the transmission of the extracted hydrogen. One end of the elastic air tube 24 passes through the mounting block 22 and is connected to the suction head 23. The other end of the elastic air tube 24 is fixedly connected by bolts, and penetrates into the interior of the delivery pipe 2 and communicates with the interior of the delivery pipe 2. The hydrogen is extracted through the suction head 23 and transmitted to the delivery pipe 2 by means of the elastic air tube 24. The extracted hydrogen can be transferred to the delivery pipe 2 for storage. The other end below the mounting block 22 is fixedly mounted with a first electromagnet 26 by bolts; a negative pressure pumping mechanism is provided on one side of the support frame 12. The negative pressure pumping mechanism can form a negative pressure space in the delivery pipe 2, and hydrogen can be extracted by means of the negative pressure pumping effect.The turntable 5 is rotatably mounted in the middle of the support frame 12, and a plurality of support rods 51 are fixedly installed on the adjacent sides of the two turntables 5 near the edges thereof by bolts. The number of support rods 51 can be selected according to the capacity of hydrogen to be extracted.

[0023] Among them, through the support rod 51 provided between the two turntables 5 and the connecting action of the fixed block 52, the box body 54 prepared with hydrogen can be intermittently rotated under the adjustment of the rotation drive mechanism. When the box body 54 stops below the suction head 23, the electric push rod 21 is synchronously driven to insert the suction head 23 into the box body 54. Through the negative pressure pumping mechanism, the negative pressure space formed in the delivery pipe 2 can be transmitted through the elastic air tube 24, and the hydrogen generated in the box body 54 and stagnant above the inside of the box body 54 is extracted with the help of the inserted suction head 23. By providing a plurality of annular support rods 51 on the turntable 5 and detachably installing the box body 54 with the help of a plurality of fixed blocks 52, the box body 54 after the hydrogen is extracted can be easily replaced and installed, thereby effectively reducing the loading and unloading time of the box body 54, greatly shortening the replacement process and reducing the handling intensity, thereby effectively improving the hydrogen extraction efficiency.

By installing the storage box 32 on the collection platform 14 in a detachable manner, the storage box 32 full of hydrogen can be conveniently replaced with the help of the first valve body 4, the second valve body 41 and the third valve body 42.

[0029] Among them, the gear 63 is driven to rotate by the servo motor 62, and the meshing action of the gear 63 and the gear ring 6 can drive the turntable 5 to rotate intermittently, so that the state of the turntable 5 can be controlled, so that the user can disassemble and replace the box body 54. By providing a ball on the protrusion 65 that fits and slides with the turntable 5, it can play a role in auxiliary support of the turntable 5, further improving the transmission stability of the gear ring 6 and the gear 63.

[0030] Working principle: When in use, the box body 54 containing hydrogen can be connected by the connection of the fixed block 52, and the gear 63 is driven by the servo motor 62 to rotate.
