[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figures 1 to 4 This embodiment proposes a multi-channel solid hydrogen storage tank activation and hydrogen filling device, including a support frame 1, a connecting strip 2, a placement plate 3, a plug hole 4, a moving strip 5, a contact frame 6, a buffer spring 7, a contact block 8, a plug post 9, a support plate 10, a connecting groove 11, an adjustment block 12, and an auxiliary mechanism.

[0025] like Figure 3 and Figure 4As shown, the connecting strip 2 is slidably connected to the support frame 1. A placement plate 3 is installed on the front of the connecting strip 2. The placement plate 3 has a groove inside, which is used to place the bottom of the multi-channel solid hydrogen storage tank. A plug hole 4 is opened on the upper surface of the placement plate 3. A moving strip 5 is slidably connected inside the placement plate 3. A contact frame 6 is installed on the inner side of the moving strip 5. A plug post 9 passes through the plug hole 4 on the outer side. The bottom end of the plug post 9 passes through the moving strip 5. A buffer spring 7 is installed inside the contact frame 6. A contact block 8 is slidably connected inside the contact frame 6. Contact grooves are provided on the inner sides of both the contact frame 6 and the contact block 8. The width of the contact groove on the contact frame 6 is greater than the width of the contact groove on the contact block 8. The contact block 8 is used to fill the area not contacted by the contact frame 6, thereby increasing the contact area between the device and the multi-channel solid hydrogen storage tank. The inner end of the buffer spring 7 is installed on the side of the contact block 8. A support plate 10 is installed on the upper surface of the placement plate 3. A connecting groove 11 is provided in the support plate 10. The adjusting block 12 is slidably connected in the connecting groove 11. The connecting groove 11 is an n-shaped groove. An auxiliary mechanism is provided on the side of the adjusting block 12.

[0026] like Figure 3 As shown, the auxiliary mechanism includes an adjusting pin 13, an adjusting frame 14, and a positioning block 15. The adjusting pin 13 is threaded through the adjusting block 12, and one end of the adjusting pin 13 threaded through the adjusting block 12 abuts against the support plate 10. The adjusting frame 14 is installed on the side of the adjusting block 12, and an adjusting groove is provided in the adjusting frame 14. The adjusting groove is slidably connected to the positioning block 15, and the positioning block 15 is slidably connected in the adjusting frame 14.

[0027] like Figure 2 As shown, a mounting plate 16 is installed on the back of the support frame 1. The upper surface of the mounting plate 16 has mounting holes 19. The mounting plate 16 is fixed above the water bath in the prior art by bolts and mounting holes 19. The function of the water bath is to perform high-temperature heating and hydrogen release heat exchange for the multi-channel solid hydrogen storage tank, and low-temperature water bath hydrogen absorption heat exchange. A movable frame 18 is installed on the front of the connecting strip 2. A push rod motor 17 is installed on the upper surface of the mounting plate 16. The push rod motor 17 needs to be powered by an external power source. The two sets of push rod motors 17 need to be controlled by an external controller to ensure that the two sets of push rod motors 17 can move synchronously. The output end of the push rod motor 17 is installed on the lower surface of the movable frame 18.

[0028] like Figure 1As shown, a water-permeable groove 20 is provided inside the placement plate 3. The function of the water-permeable groove 20 is to reduce the resistance of the placement plate 3. Four sets of moving blocks 21 are slidably connected inside the support frame 1. An auxiliary pipe 22 passes through the inside of the outer moving block 21, and an inflation pipe 23 passes through the inside of the inner moving block 21. The outer surfaces of the auxiliary pipe 22 and the inflation pipe 23 are rotatably connected with threaded sleeves 24. The auxiliary pipe 22 is a pipeline for discharging inert gas (such as nitrogen), and the inflation pipe 23 is a pipeline for discharging hydrogen. The rear end of the auxiliary pipe 22 is connected to the output end of the gas storage tank in the prior art through a control valve. The rear end of the inflation pipe 23 is connected to the output end of the hydrogen tank in the prior art through a control valve. The auxiliary pipe 22 and the inflation pipe 23 are connected to the multi-channel of the solid hydrogen storage tank through the threaded sleeves 24.

[0029] It should be noted that both the auxiliary pipe 22 and the gas filling pipe 23 are flexible tubes, and they will not be broken during the up-and-down movement of the multi-channel solid hydrogen storage tank.

[0030] Working principle: The controller adjusts the two sets of push rod motors 17, and the bolts in the prior art are used to fix the mounting plate 16 above the water bath, so that the placement plate 3 is located above the water bath.

[0031] Place the multi-channel solid hydrogen storage tank in the placement plate 3, and move the contact frame 6 inward to drive the moving bar 5 inward. The moving bar 5 moves inward along the placement plate 3, and the contact frame 6 moves inward to drive the contact block 8 inward. The contact frame 6 and the contact block 8 move inward and contact the outer surface of the multi-channel solid hydrogen storage tank, so that the contact block 8 compresses the buffer spring 7 and fills the part that the contact frame 6 did not contact. After the movement is complete, the insertion post 9 is inserted into the moving bar 5 through the insertion hole 4 located in the middle.

[0032] The manipulator moves the adjustment block 12 upward along the connecting groove 11. The upward movement of the adjustment block 12 causes the adjustment frame 14 to move upward. The upward movement of the adjustment frame 14 causes the positioning block 15 to move upward. The adjustment block 12 first moves longitudinally along the connecting groove 11, and then moves laterally along the connecting groove 11. During this process, the manipulator moves the positioning block 15 inward along the adjustment frame 14, so that the positioning block 15 moves to the outside of the multi-channel of the solid hydrogen storage tank. As the adjustment frame 14 moves inward, the positioning block 15 contacts the multi-channel of the solid hydrogen storage tank. Then, the adjustment pin 13 is rotated clockwise to press against the support plate 10.

[0033] The threaded sleeve 24 is used to connect the auxiliary pipe 22 and the gas filling pipe 23 to the multi-channel solid hydrogen storage tank. The push rod motor 17 is started. The output end of the push rod motor 17 moves downward, which drives the moving frame 18 to move downward. The moving frame 18 moves downward, which drives the connecting strip 2 to move downward. The connecting strip 2 moves downward along the support frame 1. The downward movement of the connecting strip 2 drives the placement plate 3 to move downward. The downward movement of the placement plate 3 drives the multi-channel solid hydrogen storage tank to move downward and enter the water bath.

[0034] The water bath treats the multi-channel solid hydrogen storage tank from the outside. Under low temperature conditions, the multi-channel solid hydrogen storage tank undergoes hydrogen absorption heat exchange, and under high temperature conditions, the multi-channel solid hydrogen storage tank undergoes hydrogen release heat exchange. The hydrogen absorption and release operations are alternately performed to activate the solid hydrogen storage tank. Finally, after the treatment is completed, the multi-channel solid hydrogen storage tank is filled with hydrogen.

[0035] It should be noted that the multi-channel designation of a solid hydrogen storage tank refers to the multiple sets of pipelines connected to it for gas inlet and outlet.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
