[0015] The present invention has the following beneficial effects:

[0016] 1. In the centralized hydrogen refueling and distributed hydrogen exchange system, multiple hydrogen tank modules filled with hydrogen can be conveniently transported to the hydrogen exchange station through the hydrogen tank transport vehicle body. The lifting position of the lifting assembly can be adjusted through the slide rail, mobile truss, first mobile wheel, second mobile wheel and support plate. The empty tank on the hydrogen exchange vehicle body can be accurately lifted and conveniently lifted and exchanged with the hydrogen tank module on the hydrogen tank transport vehicle body. The centralized hydrogen refueling and distributed hydrogen exchange mode can effectively reduce the cost of laying out and building hydrogen refueling stations. When lifting the empty hydrogen tank module, the de-icing seat can be connected to the lifting assembly through the support column, so that the de-icing seat can be put on the hydrogen tank module when the lifting assembly moves down.

[0017] The cooperation of the servo motor, the first gear and the second gear can drive the first rotating shaft on the de-icing seat to rotate, and the cooperation of the second bevel gear and the first bevel gear can achieve the purpose of synchronous rotation of several ice-knocking assemblies fixed on the first rotating shaft and the second rotating shaft. When the de-icing seat moves down, the ice on the surfaces of the hydrogen tank module and the hydrogen exchange base can be knocked off in all directions. At the same time, through several warm air nozzles installed on the first strip plate and the second strip plate in the de-icing seat, the purpose of blowing warm air on the surface of the hydrogen tank module and the hydrogen exchange base can be achieved, so that the ice can be melted by heat. The cooperation of the warm air nozzle and the ice-knocking assembly can also achieve the purpose of reducing the bonding strength at the connection between the hydrogen exchange base and the hydrogen tank module. During the hoisting process, the time and difficulty of hydrogen exchange can be reduced, and the efficiency of hydrogen exchange can be improved.

[0018] 2. In this centralized hydrogen refueling and distributed hydrogen exchange system, when the de-icing seat moves to the hydrogen exchange base, the wedge-shaped contact head can come into contact with the hydrogen tank module. Through the linkage between the wedge-shaped contact head, the first contact bracket, the first contact rod, the L-shaped contact bracket, and the second contact rod, the positions of the second strip plate and the first strip plate can be adjusted, so that the warm air nozzle can be moved out of the de-icing seat and closer to the connection between the hydrogen exchange base and the hydrogen tank module, so that the warm air can better act on the connection, improve the melting effect of ice cubes, and further reduce the bonding strength;

[0019] The first sliding bracket fixed on the back side of the first strip plate can slide on the first interference rod, and the several first interference strips fixed on the first rotating shaft can rotate synchronously with the first rotating shaft during the ice knocking process. Through the cooperation of the second interference frame, the several first interference strips can be able to intermittently reciprocate with the second interference frame, prompting the first strip plate to drive some warm air nozzles to move back and forth horizontally. Similarly, when the several second interference strips fixed on the second rotating shaft conflict with the third interference frame during rotation, the cooperation of the second sliding bracket can prompt the second strip plate to drive some warm air nozzles to move back and forth horizontally, which can increase the range of warm air blowing, reduce dead angles, and further improve the ice melting effect at the connection between the hydrogen exchange base and the hydrogen tank module.

[0020] 3. In the centralized hydrogen refueling and distributed hydrogen exchange system, the first hollow rod can be rotatably connected by the first rotating block provided on the first strip plate. When the first strip plate moves back and forth in the de-icing seat, it drives the fourth friction frame to interfere with the side wall of the de-icing seat, so that the fourth friction frame slides on the first strip plate and pushes the third friction bar to rotate, prompting the several warm air nozzles on the first hollow rod to rotate vertically. Similarly, when the second strip plate moves back and forth in the de-icing seat, the fifth friction frame can be caused to interfere with the side wall of the de-icing seat, so that the fifth friction frame interferes with the fourth friction bar at the end of the second hollow rod, prompting the second hollow rod to drive the warm air nozzle to rotate vertically, so that the rotating warm air nozzle can further increase the range of warm air blowing, accelerate the melting speed of ice at the connection between the hydrogen exchange base and the hydrogen tank module, and improve the replacement efficiency of the hydrogen tank module.

Several ice-knocking components are installed on the first rotating shaft 1 and the second rotating shaft 13. The de-icing seat 12 is symmetrically provided with a first strip plate 14 and a second strip plate 15. Several warm air nozzles 16 are provided on the first strip plate 14 and the second strip plate 15.

[0036] The lifting assembly includes a servo hydraulic cylinder 61, and the servo hydraulic cylinder 61 is fixed on the support plate 6. A mounting plate 62 is fixed on the piston rod of the servo hydraulic cylinder 61. Several positioning blocks 63 and a rotating electric cylinder 64 are fixed on the mounting plate 62.

[0037] A servo motor 121 is fixed on the de-icing seat 12, a first gear 122 is fixed on one of the first rotating shafts 1, a second gear 123 is fixed on the motor shaft of the servo motor 121, the second gear 123 and the first gear 122 are meshed with each other, first bevel gears 124 are fixed at both ends of the first rotating shaft 1, and second bevel gears 125 are fixed at both ends of the second rotating shaft 13, the first bevel gear 124 and the second bevel gear 125 are meshed with each other.

[0038] The ice knocking assembly includes a fixed block 131 , one end of which is fixed to the first rotating shaft 1 , a knocking head 132 is rotatably connected to the fixed block 131 , and a first torsion spring 133 is connected between the knocking head 132 and the fixed block 131 .

[0039] refer to Figure 1-Figure 5First, the hydrogen tank transport vehicle body 3 transports several hydrogen tank modules 9 filled at the hydrogen filling station to the hydrogen exchange station and docks at one side of the hydrogen exchange station. The hydrogen exchange vehicle body 2 docks at the other side of the hydrogen exchange station when exchanging hydrogen. The mobile truss 47 moves on the slide rail 4 through the first moving wheel 5, and the longitudinal movement position of the hoisting assembly fixed on the support plate 6 can be adjusted. The second moving wheel 7 fixed on the support plate 6 moves on the mobile truss 47, and the lateral movement position of the hoisting assembly can be adjusted, so that the hoisting assembly reaches the top of the hydrogen tank module 9 of the hydrogen exchange vehicle body 2. The piston rod of the servo hydraulic cylinder 61 in the hoisting assembly drives the mounting plate 62 to move downward, so that the de-icing seat 12 fixed under the support column 11 is sleeved on the hydrogen tank module 9 and moves toward the connection between the hydrogen tank module 9 and the hydrogen exchange base 8. At the same time, the servo motor 121 is started, and the second gear 123 fixed on the motor shaft of the servo motor 121 drives the first gear 1 22 rotates, prompting the first rotating shaft 1 to rotate synchronously, and at the same time, the first bevel gear 124 fixed on the first rotating shaft 1 can mesh with the second bevel gears 125 fixed at both ends of the second rotating shaft 13, so that the two symmetrical first rotating shafts 1 and the second rotating shaft 13 can rotate synchronously, so that several ice-beating components can operate synchronously, wherein the fixed block 131 rotates, and the striking head 132 can be driven to rotate, so that the striking head 132 can strike the hydrogen tank module 9 and the ice cubes at the connection between the hydrogen tank module 9 and the hydrogen exchange base 8. If a relatively solid ice cube is encountered, the striking head 132 is resisted and can rotate on the fixed block 131 to reduce the contact angle with the ice cube. The first torsion spring 133 accumulates force, which can protect the striking head 132, reduce the deformation, and facilitate the next striking head 132 to continue striking the ice cube until the ice cube falls off;

The cooperation of the warm air nozzle 16 and the ice knocking assembly can also reduce the bonding strength at the connection between the hydrogen exchange base 8 and the hydrogen tank module 9, and the time and difficulty of hydrogen exchange can be reduced during the hoisting process, thereby improving the efficiency of hydrogen exchange. When the positioning block 63 is against the hoisting bracket 10 on the hydrogen tank module 9, the hoisting position can be adjusted, and the rotating electric cylinder 64 is started. The rotating electric cylinder 64 drives the clamping block 65 to rotate, causing the clamping block 65 to be stuck on the hoisting bracket 10. When the piston rod of the servo hydraulic cylinder 61 is retracted, the empty hydrogen tank module 9 can be separated from the hydrogen exchange base 8, and the empty hydrogen tank module 9 can be moved to the hydrogen tank transport vehicle body 3, and then the full hydrogen tank module 9 is replaced on the hydrogen exchange vehicle body 2. By adopting centralized hydrogenation and distributed hydrogen exchange modes, the cost of layout and construction of hydrogen refueling stations can be effectively reduced.

[0041] Example 2: This example is an improvement based on Example 1. For details, please refer to Figures 1 to 11 A first resistance rod 17 is slidably connected to the de-icing seat 12, a sixth spring 171 is connected between the first resistance rod 17 and the de-icing seat 12, a first sliding bracket 18 is fixed to the back of the first strip plate 14, and the first resistance rod 17 is elastically connected to the first sliding bracket 18 through a first spring 19.

The third spring 23 stores force. During the movement, one end of the wedge-shaped contact head 22 abuts against the first contact bracket 20. The first contact bracket 20 slides downward on the support column 11 under the abutment. The second spring 21 stores force, so as to achieve the purpose of the lower end of the first contact bracket 20 moving downward abutting against the first contact rod 17, prompting the first contact rod 17 to drive the first strip plate 14 fixed on the first sliding bracket 18 to move horizontally.

At the same time, the L-shaped interference frame 28 fixed on the first interference rod 17 can move synchronously with the first interference rod 17, so as to achieve the purpose of interference with the second interference rod 26, so that the second interference rod 26 drives the second strip plate 15 fixed on the second sliding bracket 24 to move horizontally. The fifth spring 27 accumulates force, so that the warm air nozzle 16 fixed on the second strip plate 15 can move out of the de-icing seat 12 and approach the connection between the hydrogen exchange base 8 and the hydrogen tank module 9, so that the warm air can better act on the connection, thereby improving the melting effect of ice cubes and further reducing the bonding strength.

[0046] In order to increase the range of warm air blowing, refer to 2- Figure 9 When the first rotating shaft 1 rotates, it can drive the plurality of first contact bars 31 to rotate synchronously, so that the plurality of first contact bars 31 can intermittently interfere with the second contact frame 29 during the rotation process. The seventh spring 30 continuously stores and releases elastic force, causing the second contact frame 29 to move downward and interfere with the first sliding bracket 18, so that the first sliding bracket 18 slides on the first interference rod 17. The first spring 19 stores force, which can realize the purpose of reciprocating movement of the first strip plate 14 in the de-icing seat 12. At the same time, when the second interference bar 34 fixed on the second rotating shaft 13 rotates, it can interfere with The purpose of the intermittent interference of the third interference frame 32 is that the tenth spring 33 continuously accumulates force and releases elastic force, causing the third interference frame 32 to move downward and interfere with the second sliding bracket 24, so that the second sliding bracket 24 slides on the second interference rod 26, and the fourth spring 25 accumulates force, which can achieve the purpose of the second strip plate 15 to move back and forth in the de-icing seat 12, so that the warm air nozzle 16 can move horizontally back and forth at the connection around the hydrogen exchange base 8 and the hydrogen tank module 9, which can increase the range of warm air blowing, reduce dead angles, and further improve the ice melting effect at the connection between the hydrogen exchange base 8 and the hydrogen tank module 9.

The fourth interference frame 39 and the first strip plate 14 approach each other, and the eighth spring 40 accumulates force, which can realize that the fourth interference frame 39 interferes with the fourth interference strip 44 fixed at the end of the second hollow rod 42, prompting the second hollow rod 42 to drive the warm air nozzle 16 to rotate in the vertical direction. The second torsion spring 37 accumulates force, so that the rotating warm air nozzle 16 can further increase the range of warm air blowing;

[0050] The two second rotating blocks 41 fixed on the second strip plate 15 can be rotatably connected to the second hollow rod 42.
