In the embodiment, an electric appliance of the device is controlled by an external controller, when the hydrogen cylinder 71 needs to be filled in the hydrogen cylinder containing box 11, the controller controls the first stepping motor 81 to rotate forwardly, the first stepping motor 81 rotates forwardly to drive the first one-way wheel 33 to transmit to the first belt pulley 15 through the transmission belt 34, at the moment, the second one-way wheel 35 does not transmit to the third bevel gear 39, the first one-way wheel 33 is a double-grooved wheel, so that the first belt pulleys 15 on two sides can be simultaneously driven to rotate, the first belt pulley 15 rotates to drive the transmission disc 13 and the hollow tube 7 to rotate, and the hollow tube 7 rotates to drive the first reciprocating screw rod 10 to slide downwards through the first thread block 8 and the first threaded hole 9; the transmission disc 13 drives the bevel gear I14 to transmit to the bevel gear II 30 while rotating, the rotation of the bevel gear II 30 drives the transmission shaft I29 and the rotation pipe 31 to rotate, the rotation of the rotation pipe 31 directly drives the threaded ring I32 to rotate, at this time, the reciprocating screw rod II 25 cannot rotate under the structure of the T-shaped support 23, the limiting pipe 24 and the L-shaped connecting rod 26, the L-shaped connecting rod 26 can directly slide leftwards by utilizing the relative rotation of the rotation pipe 3 and the reciprocating screw rod II 25, the sliding of the L-shaped connecting rod 26 directly drives the rack I27 to drive the transmission gear 22 to rotate, the rotation of the transmission gear 22 drives the connecting rope 20 to release through the rotating shaft 19, the lower end of the connecting rope 20 moves downwards by releasing the connecting rope 20, and finally the hydrogen bottle containing box 11 descends to a certain height (as shown in figure 3), one end of the hydrogen bottle containing box 11 can have a stable structure under the connection effect of the reciprocating, the hydrogen bottle containing box 11 is connected through the connecting rope 20, so that the hydrogen bottle containing box 11 can be inclined at a certain angle after the hydrogen bottle containing box 11 is completely descended, the first stepping motor 81 stops rotating forwards, the hydrogen bottles 71 can be conveniently filled, the hydrogen bottles 71 are manually filled into the hydrogen bottle containing box 11 one by one, and different hydrogen bottles 71 can be isolated through the action of the rectangular partition plate 69; after the manual filling is finished, the controller controls the first stepping motor 81 to rotate forwards again, and the first reciprocating screw rod 10 and the second reciprocating screw rod 25 are used for resetting the hydrogen bottle containing box 11 (as shown in fig. 9);
at the moment, the first circular through
as shown in fig. 6, for convenience of expressing the docking process, the hydrogen bottles are referred to as a No. 1 hydrogen bottle, a No. 2 hydrogen bottle, a No. 3 hydrogen bottle, and a No. 4 hydrogen bottle in sequence from top to bottom;
after the
when the hydrogen block in the No. 1 hydrogen bottle is used up, the controller controls the electric hydraulic rod 85 to contract, the contraction of the electric hydraulic rod 85 drives the driving wheel II 84 to be meshed with the other driving wheel I62, then the operation is repeated, the stepping motor II 83 rotates forwards to indirectly drive the other sealing
then the controller controls the second stepping motor 83 to rotate reversely, the reverse rotation of the second stepping motor 83 indirectly drives the third one-way wheel 63 not to transmit to the second driven gear 47, the fourth one-
then the controller controls the second stepping motor 83 to rotate forwards, and the forward rotation of the second stepping motor 83 indirectly drives the first sealing joint 52 to be in butt joint with the second sealing
The technical solutions described above only represent the preferred technical solutions of the present invention, and some possible modifications to some parts of the technical solutions by those skilled in the art all represent the principles of the present invention, and fall within the protection scope of the present invention.
