Detailed implementation manners

[0034] In order to clearly and completely describe the objectives, technical solutions and advantages of the present invention, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only a part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0035] Please refer to Figures 1-13 , the present invention provides the following technical solutions:

[0036] Embodiment 1: A quick-insert integrated hydrogen fuel cell system for a hydrogen-powered drone, including a pre-installed base 1. A hydrogen fuel cell 2 is vertically inserted through a guiding component at the upper end of the pre-installed base 1. The guiding component includes four guiding vertical plates 4. A fan housing 3 is horizontally arranged at the upper end of the hydrogen fuel cell 2. Two fans 12 are horizontally and symmetrically arranged at the upper end of the fan housing 3. A battery intake groove 18 is formed on one side inside the hydrogen fuel cell 2. A battery exhaust valve 13 is connected and inserted in a communicating manner on one side of the hydrogen fuel cell 2. One side of the battery exhaust valve 13 penetrates through the upper end of the fan housing 3 and is connected to an exhaust pipe 14 in a communicating manner. One side of the guiding vertical plate 4 is in contact with the side surface of the hydrogen fuel cell 2. Two guiding grooves are symmetrically formed on the side of the guiding vertical plate 4 close to the hydrogen fuel cell 2. Guiding strips 5 are vertically arranged on the side of the hydrogen fuel cell 2 close to the guiding grooves. The guiding strips 5 of the hydrogen fuel cell 2 are vertically and movably inserted into the guiding grooves of the guiding vertical plate 4. A circuit control box 16 is arranged on one side of the hydrogen fuel cell 2. A vertical socket is arranged at the lower end of the circuit control box 16. A plug-in row 17 is horizontally arranged directly below the vertical socket on the pre-installed base 1. When the lower end of the hydrogen fuel cell 2 is in contact with the upper end of the pre-installed base 1, the plug-in row 17 is inserted into the vertical socket of the circuit control box 16. An electric heating module 15 is arranged on the side of the exhaust pipe 14 away from the battery exhaust valve 13. The pre-installed base 1 is fixedly installed at the battery placement position of the drone through bolts. When it is necessary to disassemble and assemble the hydrogen fuel cell 2 for use, the hydrogen fuel cell 2 can be stably placed in the pre-installed base 1 through the guiding cooperation of the guiding vertical plate 4 and the guiding strips 5.

[0037] The hydrogen fuel cell 2 contains a power supply positive and negative socket, an internal temperature sensor, and an ambient temperature sensor. The working state information of the hydrogen fuel cell 2 is used for power transmission and information interaction with the hydrogen-powered drone through the circuit control box 16. The circuit control box 16 adjusts the rotation speed of the fan 12 according to the preset program based on the air temperature entering the hydrogen fuel cell 2 and the temperature inside the hydrogen fuel cell 2, and regulates the hydrogen fuel cell 2 to maintain an appropriate working temperature and sufficient oxygen supply.

[0038] The battery exhaust valve 13 can adjust the exhaust interval according to the output power of the fuel cell to discharge the water generated during the operation of the hydrogen fuel cell 2, promoting the efficient operation of the hydrogen fuel cell 2. The electric heating module 15 can effectively prevent the exhaust port of the hydrogen fuel cell 2 from freezing and blocking at low temperatures, ensuring the low-temperature environmental adaptability of the hydrogen fuel cell 2.

[0039] An internal DC voltage stabilization module can be set in the circuit control box 16. Due to the different output powers resulting in different voltages, the built-in power supply voltage stabilization module can stabilize the output voltage of the hydrogen fuel cell 2 within a certain range, ensuring the normal operation of the drone.

[0040] The fan housing 3 is tightly connected to each side end plate of the hydrogen fuel cell 2. A negative pressure is generated in the fan housing by the fan 12 to extract the air at the front end of the hydrogen fuel cell 2 for reaction heat dissipation.

[0041] A quick-installation fixing component is provided to quickly fix the connection between the pre-installed base 1 and the hydrogen fuel cell 2. The quick-installation fixing component includes two installation inserts 8 and two installation mating vertical plates 6. The two installation mating vertical plates 6 are respectively and vertically symmetrically arranged on both sides of the pre-installed base 1. The two installation inserts 8 are respectively horizontally inserted and arranged on one side of the fan housing 3 close to the installation mating vertical plate 6, and one side of the installation insert 8 penetrates through the installation mating vertical plate 6 and is inserted into the installation mating vertical plate 6. Telescopic grooves 7 are respectively opened at the upper ends of one side of the fan housing 3 close to the installation mating vertical plate 6. The two installation inserts 8 are respectively horizontally placed in the two telescopic grooves 7. One side of the two installation inserts 8 respectively horizontally and movably penetrates through the telescopic grooves 7. Installation slots 11 are respectively horizontally opened on one side of the installation mating vertical plate 6 close to the installation insert 8. One side of the installation insert 8 penetrating through the telescopic groove 7 is horizontally inserted into the installation slot 11, and one side of the lower end of the installation insert 8 inserted into the installation slot 11 is an inclined surface. When the hydrogen fuel cell 2 is pressed down from above the pre-installed base 1, the installation insert 8 can be retracted into the fan housing 3 through the inclined surface of the installation insert 8 and then inserted into the installation slot 11.

[0042] On the side far from the installation mating vertical plate 6 in the telescopic groove 7, three spring guide rods 9 are horizontally and symmetrically arranged. The installation insert 8 is horizontally and movably sleeved on the three spring guide rods 9 placed in the telescopic groove 7. Installation springs 10 are sleeved on the three spring guide rods 9, and a pull-back block is provided at the upper end of the installation insert 8 close to the installation spring 10, which is convenient for the adaptation disassembly and assembly and quick maintenance and repair of the hydrogen-powered fuel cell of the drone.

[0043] In this embodiment, when the hydrogen fuel cell 2 needs to be installed, through the correspondence between the guide strip 5 and the guide groove of the guide vertical plate 4, and the correspondence between the power plug 17 and the circuit control box 16, the hydrogen fuel cell 2 stably slides vertically downward. When the installation insert 8 reaches the position of the installation mating vertical plate 6, under the action of the inclined surface, the installation insert 8 squeezes the installation spring 10 along the telescopic groove 7 and the spring guide rod 9. At this time, the installation insert 8 retracts into the telescopic groove 7. Then, during the continuous descent of the hydrogen fuel cell 2, the installation insert 8 is horizontally inserted into the installation slot 11 of the installation mating vertical plate 6 under the elastic action of the installation spring 10 to limit and fix the up-and-down movement of the hydrogen fuel cell 2.

[0044] Embodiment 2: On the basis of Embodiment 1, a hydrogen gas connection strengthening component is provided to strengthen the sealing and maintain the hydrogen gas input connection of the hydrogen fuel cell 2. The hydrogen gas connection strengthening component includes a hydrogen gas connector 20, a hydrogen gas docking pipe 23, a strengthening sealing ring 26 and a pressing ring 27. One side of the hydrogen gas connector 20 is communicated with the battery air inlet groove 18. The hydrogen gas docking pipe 23 is inserted into the hydrogen gas connector 20 and is communicated with the battery air inlet groove 18. The inner peripheral side of the strengthening sealing ring 26 is in extrusion contact with the outer peripheral side of the hydrogen gas docking pipe 23. One side of the hydrogen gas connector 20 is provided with an installation turntable 19. The center of one side of the installation turntable 19 is provided with a shaft rod. One side of the shaft rod penetrates through one side of the hydrogen fuel cell 2 through a sealing bearing and is inserted into the battery air inlet groove 18. A docking air groove 24 is vertically opened at the lower end inside the hydrogen gas connector 20. A connection groove 21 is opened in the center of the shaft rod of the installation turntable 19 to communicate the docking air groove 24 and the battery air inlet groove 18. When the hydrogen fuel cell 2 is assembled and installed with the pre-installed base 1, the hydrogen gas connector 20 is docked and connected with the hydrogen gas docking pipe 23 through the lower docking air groove 24. At this time, hydrogen gas is sent into the hydrogen gas docking pipe 23, and the hydrogen gas can enter the battery air inlet groove 18 through the docking air groove 24 and the connection groove 21 to complete the hydrogen gas input. The hydrogen gas in the hydrogen gas docking pipe 23 is provided by the hydrogen gas transfer pipe 22. One side of the lower end of the hydrogen gas transfer pipe 22 is provided with a hose connector, and the hose connector is hermetically connected with the hose of the hydrogen gas cylinder.

[0045] The pre-installed base 1 is vertically provided with a hydrogen gas transfer pipe 22 directly below the hydrogen gas connector 20. The hydrogen gas docking pipe 23 is vertically communicated and arranged at the center of the upper end of the hydrogen gas transfer pipe 22. The upper end of the hydrogen gas docking pipe 23 is vertically inserted into the docking air groove 24, and a sealing gasket is arranged at the upper end of the hydrogen gas docking pipe 23 inserted into the docking air groove 24. A shock-absorbing sealing pad 32 is arranged on the side of the hydrogen gas transfer pipe 22 in contact with the hydrogen gas connector 20. When the hydrogen gas connector 20 is connected to the hydrogen gas docking pipe 23, the hydrogen gas docking pipe 23 can press and seal the connection between the hydrogen gas connector 20 and the hydrogen gas docking pipe 23 through the sealing gasket and the shock-absorbing sealing pad 32.

[0046] An annular movable groove 25 is formed on one side of the docking gas groove 24 inside the hydrogen connector 20. The pressing ring 27 is vertically and movably inserted into the annular movable groove 25. An annular placement groove is formed on one side inside the annular movable groove 25 and communicates with the docking gas groove 24. The reinforced sealing ring 26 is horizontally placed in the annular placement groove. The inner and outer peripheral sides of the reinforced sealing ring 26 are respectively inserted into the docking gas groove 24 and the annular movable groove 25. An annular sealing groove is formed on the outer peripheral side of the hydrogen docking pipe 23 close to the reinforced sealing ring 26 when the hydrogen docking pipe 23 is inserted into the docking gas groove 24. When the inner peripheral groove of the pressing ring 27 abuts against the outer peripheral side of the reinforced sealing ring 26, the inner peripheral side of the reinforced sealing ring 26 is inserted into the annular sealing groove of the hydrogen docking pipe 23. A movable plate groove 28 is horizontally formed on the side of the hydrogen connector 20 away from the docking gas groove 24. A movable pressing plate 29 is horizontally arranged in the movable plate groove 28. A plurality of synchronous connecting rods 30 are vertically and symmetrically arranged at the lower end of the movable pressing plate 29. The lower ends of the plurality of synchronous connecting rods 30 are respectively movably inserted into the annular movable groove 25 and connected to the upper end of the pressing ring 27. A return spring 31 is vertically arranged at the center of the lower end inside the movable plate groove 28, and the upper end of the return spring 31 abuts against the center of the lower end of the movable pressing plate 29. When the movable pressing plate 29 and the synchronous connecting rods 30 descend, the synchronous connecting rods 30 push the pressing ring 27 to descend in the annular movable groove 25. At this time, the pressing ring 27 abuts against the outer peripheral side of the reinforced sealing ring 26. Since the outer peripheral side of the reinforced sealing ring 26 is placed in the annular movable groove 25 in the natural state, the pressing ring 27 can squeeze the reinforced sealing ring 26 to deform towards its inner side at this time. Therefore, the inner peripheral side of the reinforced sealing ring 26 is in close contact with the hydrogen docking pipe 23, strengthening the sealing effect of the hydrogen docking pipe 23 inserted into the docking gas groove 24.

[0047] At the upper end of the movable plate groove 28, a mating hole is provided through the hydrogen connection head 20. The diameter of the mating hole is equal to the diameter of the docking gas groove 24. A strip-shaped chute 33 is horizontally provided at the center of the installation insert block 8. Inside the telescopic groove 7, a guide rod sleeve 34 is vertically provided on one side of the strip-shaped chute 33. A rod groove is vertically penetrated through the center of the guide rod sleeve 34. A downward pressure control rod 35 is vertically inserted into the rod groove. The lower end of the downward pressure control rod 35 vertically and movably penetrates the rod groove and the mating hole and is inserted into the movable plate groove 28. One side of the downward pressure control rod 35 placed inside the movable plate groove 28 abuts against the upper end of the movable pressure plate 29. On both sides above the guide rod sleeve 34 of the downward pressure control rod 35, two constraint rods 37 are symmetrically provided horizontally. On both sides of the upper end of the installation insert block 8, two convex blocks are symmetrically provided. Constraint grooves 36 are provided at the upper ends of the two convex blocks. A limiting elastic block 38 is provided on one side of each of the constraint grooves 36. The width of the constraint groove 36 is equal to the diameter of the constraint rod 37. When one side of the installation insert block 8 is inserted into the installation slot 11, the two constraint rods 37 of the downward pressure control rod 35 are respectively horizontally inserted into the two constraint grooves 36, and the upper end of the constraint rod 37 abuts against the lower end of the limiting elastic block 38. A pressing piece is provided at the upper end of the downward pressure control rod 35 penetrating through the guide rod sleeve 34. When the downward pressure control rod 35 is pressed downward through the pressing piece, the lower end of the downward pressure control rod 35 is inserted into the movable plate groove 28 and provides power for the downward movement of the movable pressure plate 29. At this time, the movable pressure plate 29 and the control pressure ring 27 pressurize and deform the reinforced sealing ring 26 to complete the strengthening of the sealing at the insertion position of the hydrogen connection pipe 23. In addition, when the downward pressure control rod 35 descends, the two constraint rods 37 on both sides of the downward pressure control rod 35 respectively cross over the limiting elastic block 38 and are inserted into the bottom of the constraint groove 36. The abutting force of the limiting elastic block 38 is greater than the resilience of the return spring 31. At this time, under the limiting action of the limiting elastic block 38, the downward pressure control rod 35 remains in place. Similarly, the positions of the pressure ring 27 and the reinforced sealing ring 26 also remain unchanged.

[0048] In this embodiment, when the hydrogen fuel cell 2 is quickly installed with the pre-installed base 1, the upper end of the hydrogen connection pipe 23 is inserted into the docking gas groove 24 of the hydrogen connection head 20. At this time, the upper pressing piece of the downward pressure control rod 35 is pressed. Then the downward pressure control rod 35 moves vertically downward. At this time, the two constraint rods 37 of the downward pressure control rod 35 cross over the limiting elastic block 38 and are inserted into the bottom of the constraint groove 36. The lower end of the downward pressure control rod 35 pushes the movable pressure plate 29 and the pressure ring 27 to descend. At this time, the pressure ring 27 squeezes the outer peripheral side of the reinforced sealing ring 26, and the reinforced sealing ring 26 generates an inward deformation. Furthermore, the reinforced sealing ring 26 can perform an encircling and strengthening seal on the hydrogen connection pipe 23, improving the efficiency and quality of hydrogen fed into the hydrogen fuel cell 2.

[0049] Embodiment 3: On the basis of Embodiment 2, when the hydrogen fuel cell 2 is in the overhaul and maintenance stage, the docking air groove 24 of the hydrogen connector 20 can be protected. Two self-positioning card slots 39 are symmetrically arranged on both sides of the installation turntable 19. One side of the hydrogen fuel cell 2 close to the installation turntable 19 is provided with a self-positioning elastic piece 40 through an installation block. And during normal use, one side of the self-positioning elastic piece 40 is inserted into the self-positioning card slot 39 on one side of the installation turntable 19. The installation turntable 19 is rotationally communicated with the battery air inlet groove 18 through a sealed bearing. When the hydrogen connector 20 is normally connected to hydrogen for use, the docking air groove 24 is vertically downward. When the hydrogen fuel cell 2 is in the non-use stage, the docking air groove 24 can be turned upward by rotating the installation turntable 19. When the docking air groove 24 is upward, the lower end of the pressing control rod 35 can be inserted into the docking air groove 24 to block the docking air groove 24 and prevent pollutants from entering the battery air inlet groove 18;

[0050] The upward or downward orientation of the docking air groove 24 of the hydrogen connector 20 can be self-positioned correspondingly through the change of the self-positioning elastic piece 40 being inserted into the two self-positioning card slots 39 respectively.

[0051] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
