For example, as shown in fig. 8 and 9, one end of the rear pushing plate 631 is mounted on the rotating rod 620, and a pressing groove 632 is formed in the center of the other end of the rear pushing plate, and a return spring 633 is disposed in the pressing groove 632. Two sets of first cooling side cavities 634 are symmetrically formed in two sides of the elastic pressing groove 632, one end of each first cooling side cavity 634 is communicated with an intermediate pipe 622, and the other end of each intermediate pipe 622 is communicated with the inner conveying pipe 621. A telescopic plate 635 is arranged in the first cooling side cavity 634, and the other end of the telescopic plate 635 extends out of the first cooling side cavity 634 and is fixedly provided with a front push plate 636. Two groups of second cooling side cavities 637 are formed in the front push plate 636, and two ends of the expansion plate 635 are respectively communicated with the cavities of the first cooling side cavity 634 and the second cooling side cavities 637. A pestle rod 639 is arranged at the center of the outer wall of one side of the front pushing plate 636, which is close to the rear pushing plate 631, and the other end of the pestle rod 639 movably penetrates into the elastic groove 632 and abuts against the return spring 633. A plurality of groups of heat conducting grooves 638 are distributed on the outer walls of the two sides of the rear pushing plate 631 and the front pushing plate 636 at equal intervals. A set of heat exchange plates 640 are mounted on the inner walls of the two sets of first cooling side cavities 634 and the two sets of second cooling side cavities 637 on the side close to the heat transfer groove 638. A heat conducting mechanism 650 is disposed in the heat conducting groove 638.
The heat conducting mechanism 650 includes a heat conducting rotary rod 651. For example, as shown in fig. 10 and 11, the heat conducting rotary rod 651 is rotatably connected to the heat conducting groove 638, and a central axis of the heat conducting rotary rod 651 coincides with a central axis of the heat conducting groove 638. A plurality of groups of heat conducting blades 652 are distributed on the side wall of the heat conducting rotary rod 651 in an annular array, an inner groove 653 is formed on one side wall of each heat conducting blade 652, and an outer bump 654 is arranged on the other side wall of each heat conducting blade 652. The other side of the outer protrusion 654 is movably attached to the inner wall of the heat conducting groove 638.
An external device filled with hydrogen gas is communicated with the feed port 611, and an external refrigerating device is communicated with the cold gas inlet 613. Then, the second motor 660 is started, and the rotating rod 620 is driven to rotate by the second motor 660. Since the distance from the rotary rod 620 to the discharge port 612 is greater than the distance from the rotary rod 620 to the feed port 611, the volume of the closed pressurizing chambers corresponding to the feed port 611 is greater than that of the closed pressurizing chambers corresponding to the discharge port 612. Since the pushing mechanism 630 is attached to the inner wall of the pressing cylinder 610 at two side walls close to the two end ports of the pressing cylinder 610 and at one side wall far from the rotating rod 620, the groups of closed pressing chambers are isolated from each other. When hydrogen enters the corresponding group of closed pressurizing chambers through the feed port 611, the volume of the space of the group of closed pressurizing chambers containing hydrogen is correspondingly reduced along with the rotation of the rotating rod 620, and the volume of hydrogen inside the chambers is gradually reduced, so that the effect of hydrogen pressurization is realized. When each group of pushing mechanisms 630 rotates, no matter which direction the front pushing plate 636 rotates, the pestle rod 639 can be pushed by the return spring 633, and then the pestle rod 639 pushes the front pushing plate 636, so that one end of the front pushing plate 636, which is far away from the pestle rod 639, is attached to the inner wall of the pressurizing cylinder 610, and the tightness of each group of closed pressurizing chambers is ensured, and thus the pressurizing effect is also ensured.
Since the rotary shaft 620 is closer to the side of the discharge port 612, the volume of the pair of closed pressurizing chambers corresponding to the discharge port 611 is larger than the volume of the pair of closed pressurizing chambers corresponding to the discharge port 612. After the hydrogen gas enters the closed pressurizing chambers corresponding to the feed port 611, the volume of the closed pressurizing chambers is gradually reduced along with the rotation of the rotating rod 620, and the volume of the hydrogen gas inside the closed pressurizing chambers is also gradually compressed. Make hydrogen can realize the pressurization in the transportation, need not to pressurize while canning, guaranteed the smoothness nature of canning work. Then, the pestle rod 639 is pushed by the return spring 633, and the pestle rod 639 pushes the front pushing plate 636, so that one end of the front pushing plate 636, which is far away from the pestle rod 639, is attached to the inner wall of the pressurizing cylinder 610, and the tightness of each group of sealed pressurizing chambers is ensured, and thus the pressurizing effect is also ensured.
Heat is generated during the compression of the hydrogen gas and the hydrogen gas will flow faster and impinge on the sets of heat transfer fins 652 and the heat in the hydrogen gas will be absorbed by the heat transfer fins. Because the inner grooves 653 are formed on the surfaces of the heat conducting blades 652, when hydrogen collides with the inner grooves 653, the heat conducting blades 652 are more easily pushed to move, so that the heat conducting rotary rod 651 rotates, and when the heat conducting blades 652 absorbing heat rotate to a side close to the heat conducting groove 638, the outer bumps 654 are used for improving the fitting degree of the heat conducting blades 652 and the inner wall of the heat conducting groove 638, so that the heat transfer efficiency is improved. The heat is then heat exchanged with the cold air introduced into the first cooling side cavity 634 or the second cooling side cavity 637 through the cold air inlet 613 using the heat exchange plate 640. The heat-conducting blades 652 with the heat conducted out leave the range of the heat-conducting groove 638 again along with the rotation of the heat-conducting rotary rod 651, and are in contact with hydrogen again, so that the heat-radiating continuity is ensured, and the heat-radiating purpose can be achieved in the compression process.
The hydrogen gas accelerates the flow rate during the compression process and impinges on the heat conductive blades 652, so that the heat conductive blades 652 can absorb heat, and the hydrogen gas more easily pushes the heat conductive blades 652 to rotate the heat conductive rotary rod 651 by means of the inner grooves 653. When the heat-conducting blade 652 rotates into the heat-conducting groove 638, the heat-conducting efficiency is improved by the high degree of adhesion between the outer protrusion 654 and the heat-conducting groove 638, so that heat is transferred to the heat-exchanging plate 640, and exchanges heat with the cold air in the first cooling-side cavity 634 or the second cooling-side cavity 637. The hydrogen can realize the heat dissipation function in the compression process, so that the safety is improved, and the heat dissipation continuity is ensured through the rotation of the heat conduction rotating rod 651.

An air delivery head fixing ball 740 is arranged at the center inside the rolling cavity 720, and the peripheral outer walls of the air delivery head fixing ball 740 are respectively in rolling fit with the rolling balls 722. The rolling cavity 720 is provided with a joint cavity 730 near one side of the conveying chain 200, an air delivery head 750 is arranged on the central axis inside the joint cavity 730, and a plurality of groups of side-pushing springs 760 are distributed on the outer wall of the air delivery head in an annular array.

And a microswitch 754 is arranged on the inner wall of one side, close to the gas transmission head fixing ball 740, of the gas transmission head 750, and the microswitch 754 is electrically connected with the electric valve. The other end of the gas transmission head 750 extends to the outside of the gas transmission cylinder 710, and a gas outlet insertion hole 751 is formed in the central axis. Be equipped with inserted block 752 on the inside axis of gas transmission head 750, one end that inserted block 752 is close to outlet hole 751 is equipped with pressing spring 753. And the other end is movably abutted against the microswitch 754.
The gas cylinder 710 is driven by the electric sliding table 510 to move towards one side of the conveying chain 200, and an air inlet valve of the air-hydrogen tank can enter the air outlet insertion hole 751 and then be inserted into the insertion block 752. And the inlet end of the air inlet valve penetrates out of one end of the insert 752 far away from the air outlet inserting hole 751. Then, as the slider 520 drives the gas delivery cylinder 710 to move continuously, the base of the air inlet valve enters the cavity of the gas delivery head 750 through the gas outlet insertion hole 751, and pushes the insertion block 752 to move towards the side of the gas delivery head fixing ball 740, so that the air inlet valve of the air hydrogen tank is inserted into the feeding pipe 741. And at this moment, the insert 752 also just props against the control pressing sheet of the microswitch 754, so that the electric valve is opened to transmit the high-pressure hydrogen to the air inlet valve, thereby realizing the canning work of the high-pressure hydrogen. After the canning operation is finished, the electric sliding table 510 drives the gas transmission cylinder 710 to move towards the other side, so that the gas inlet valve is separated from the gas transmission head 750, the inserting block 752 resets under the action of the pressing spring 753, and the inserting block is separated from the microswitch 754, so that the electric valve is closed, the automatic canning function is realized, manual operation is not needed, the automation degree of the device is improved, and the labor intensity is reduced.
