Description

Technical Field

[0001] This utility model relates to the field of teaching equipment technology, and in particular to a hydrogen fuel cell-based teaching equipment with split-drive and integrated control. Background Technology

[0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. The basic principle is the reverse reaction of water electrolysis. Hydrogen and oxygen are supplied to the anode and cathode, respectively. After hydrogen diffuses outward through the anode and reacts with the electrolyte, it releases electrons and reaches the cathode through an external load.

[0003] In the prior art, Chinese patent CN215770166U proposes a novel teaching device for automotive new energy batteries, which allows students to observe the battery around a circular guide rail, making it easier for students to observe the battery and solving the problem that existing teaching devices for automotive new energy batteries are not conducive to students' observation of the battery, thus affecting the quality of new energy battery teaching. However, in practical applications, there are still problems such as the small operating space of the display stand used by the existing teaching equipment. Although each sub-device can be displayed individually, due to the limited space in front of the operating stand, the control devices are all fixedly installed on the operating stand, which cannot provide the space required for multiple students to operate. This leads to the problem that the equipment is idle when students are practicing, and the students have long waiting time to operate. Therefore, we disclose a hydrogen fuel cell split-control teaching device. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a hydrogen fuel cell split-drive control teaching device to solve the problem that the equipment is idle and the students have long waiting time to operate it during practice.

[0007] Preferably, a limiting rod is fixedly connected to the lower end of the second connecting rod, a third rotating groove is provided at the upper end of the second rotating groove, a second limiting groove is provided on one side of the third rotating groove, and the limiting rod is slidably connected in the third rotating groove and the second limiting groove.

[0008] Preferably, the second connecting rod is a T-shaped rod, and the first connecting rod is slidably connected in the third rotating groove.

[0009] Preferably, the second baffle is not connected to the ratchet, a spring is fixedly connected to the lower end of the first baffle, one end of the spring is fixedly connected to the fixed platform, and the first rotating groove is a cross groove.

[0010] Preferably, the connecting block is T-shaped, the first limiting groove includes a T-shaped groove and a rectangular groove, anti-slip grooves are provided on both sides of the control panel, and one end of the control panel extends to the outside of the first control console.

The control panel independently controls the corresponding display panel modules, and the second control console can control all modules of the display panel.

[0012] The beneficial effects of this utility model are: the control panel controls the corresponding modules of the display panel through the transmission line and the first control console, so that the students can take the control panel out from one side of the first control console and stand in a position away from the display panel to control the corresponding modules of the display panel. This allows multiple students to operate and practice different modules of the display panel at the same time, improving the utilization rate and practice efficiency of the display panel.

[0027] As a preferred embodiment of this example, Figures 2-6As shown, the top of the fixed platform 1 is provided with several first limiting grooves 7, and the connecting block 6 is slidably connected in the first limiting grooves 7. The lower end of the first limiting groove 7 is provided with a first rotating groove 10, and a rotating shaft 12 is rotatably connected in the first rotating groove 10. The rotating shaft 12 is wound with the transmission line 11. One end of the rotating shaft 12 is fixedly connected with a ratchet 13 and a coil spring 14. One end of the coil spring 14 is fixedly connected to the fixed platform 1. One end of the first rotating groove 10 is provided with a second rotating groove 15, and both the ratchet 13 and the coil spring 14 rotate in the second rotating groove 15. One end of the fixed platform 1 is rotatably connected with a first baffle 16 and a second baffle 17. The first baffle 16 is movably engaged with the ratchet 13. The second baffle 17 is located above the first baffle 16, and the top end of the second baffle 17 is rotatably connected to... A first connecting rod 18 is connected, and a second connecting rod 19 is rotatably connected to the top of the first connecting rod 18. One end of the second connecting rod 19 extends to the outside of the fixed platform 1 and is fixedly connected to a pull rod 20. The connecting block 6 is T-shaped. The first limiting groove 7 includes a T-shaped groove and a rectangular groove. A limiting rod 22 is fixedly connected to the lower end of the second connecting rod 19. A third rotating groove 21 is opened at the upper end of the second rotating groove 15. A second limiting groove 8 is opened on one side of the third rotating groove 21. The limiting rod 22 is slidably connected in the third rotating groove 21 and the second limiting groove 8. The second connecting rod 19 is a T-shaped rod, and the first connecting rod 18 is slidably connected in the third rotating groove 21. The second baffle 17 is not connected to the ratchet 13. A spring piece is fixedly connected to the lower end of the first baffle 16. One end of the spring piece is connected to the fixed platform 1. The platform 1 is fixedly connected. The first rotating groove 10 is a cross-shaped groove. Several first limiting grooves 7 are provided at the top of the platform 1. The connecting block 6 is slidably connected in the first limiting groove 7, so that the first limiting groove 7 restricts the movement direction of the connecting block 6. The first rotating groove 10 is provided at the lower end of the first limiting groove 7. A rotating shaft 12 is rotatably connected in the first rotating groove 10. The rotating shaft 12 is wound around the transmission line 11, so that the rotating shaft 12 can wind up the transmission line 11. A ratchet 13 and a coil spring 14 are fixedly connected to one end of the rotating shaft 12. One end of the coil spring 14 is fixedly connected to the platform 1, so that the coil spring 14 can restrict the ratchet 13 to rotate in one direction, so that the coil spring 14 can help the rotating shaft 12 to return to its original rotation. A first limiting groove 7 is provided at one end of the first rotating groove 10. The ratchet 13 and coil spring 14 both rotate within the second rotating groove 15, thus restricting their positions. A first baffle 16 and a second baffle 17 are rotatably connected to one end of the fixed platform 1. The first baffle 16 is movably engaged with the ratchet 13, and the second baffle 17 is located above the first baffle 16, allowing the first and second baffles 16 to work together to restrict the ratchet 13 from rotating in one direction. A first connecting rod 18 is rotatably connected to the top of the second baffle 17, and a second connecting rod 19 is rotatably connected to the top of the first connecting rod 18. One end of the second connecting rod 19 extends to the outside of the fixed platform 1 and is fixedly connected to a lever 20, allowing the trainee to move the second connecting rod 19 and the first connecting rod 18 by lifting the lever 20.Then, the second baffle 17 is moved, so that the second baffle 17 no longer restricts the first baffle 16. The first baffle 16 is engaged with the ratchet 13, so that the ratchet 13 and the rotating shaft 12 are reset and rotated with the help of the coil spring 14, quickly winding up the transmission line 11, which is convenient to use and easy to operate. The connecting block 6 is T-shaped, and the first limiting groove 7 includes a T-shaped groove and a rectangular groove, so that the first limiting groove 7 can limit the movement position of the connecting block 6, so that the control plate 5 can be plugged into the connecting plug 9, or the control plate 5 can be moved out of the first limiting groove 7 for remote operation, which is convenient for multiple students to practice at the same time. The lower end of the second connecting rod 19 is fixedly connected to the limiting rod 22. The upper end of the second rotating groove 15 is provided with a third rotating groove 21, and a second limiting groove 8 is provided on one side of the third rotating groove 21. The limiting rod 22 is slidably connected in the third rotating groove 21 and the second limiting groove 8, so that the second limiting groove 8 restricts the movement direction of the limiting rod 22, and thus restricts the movement direction of the second connecting rod 19, so that the operation is convenient. Before lifting the lever 20, the author needs to first rotate the limiting rod 22 from the second limiting groove 8 to the third rotating groove 21 via the second connecting rod 19. Only then can the lever 20 be lifted, improving the positional stability of the second baffle 17. The second connecting rod 19 is T-shaped, allowing the lever 20 to lift the first connecting rod 18. The first connecting rod 18 is slidably connected to the third rotating groove 21, thus restricting the movement of the first connecting rod 18. The second baffle 17 is not connected to the ratchet 13, so that the second baffle 17 does not interfere with the rotation of the ratchet 13. A spring is fixedly connected to the lower end of the first baffle 16, and one end of the spring is fixedly connected to the fixed platform 1, so that the position of the first baffle 16 is restricted by the spring, preventing the first baffle 16 from falling naturally under its own weight and disengaging from the ratchet 13. The first rotating groove 10 is a cross-shaped groove, so that the transmission line 11 can enter the first limiting groove 7 from the upper end of the first rotating groove 10 and connect with the connecting block 6.

[0028] Working principle: When in use, after the control panel 5 is plugged into the connector 9, it can transmit signals to the first control panel 2, causing the first control panel 2 to disconnect the control panel 5. At this time, only the second control panel 4 can control the display panel 3. Since the control panel 5 can control the corresponding modules of the display panel 3 through the transmission line 11 and the first control panel 2, the trainee can take the control panel 5 out from one side of the first control panel 2 and stand in a position away from the display panel 3 to control the corresponding modules of the display panel 3. This allows multiple trainees to operate and practice different modules of the display panel 3 at the same time, improving the utilization rate and practice efficiency of the display panel 3.

[0029] A first rotating groove 10 is formed at the lower end of the first limiting groove 7. A rotating shaft 12 is rotatably connected within the first rotating groove 10. The rotating shaft 12 is wound around the transmission line 11, allowing the rotating shaft 12 to wind up the transmission line 11. A ratchet 13 and a coil spring 14 are fixedly connected to one end of the rotating shaft 12. One end of the coil spring 14 is fixedly connected to the fixed platform 1, allowing the coil spring 14 to restrict the ratchet 13 from rotating in one direction and also to help the rotating shaft 12 to return to its original position. A second rotating groove 15 is formed at one end of the first rotating groove 10. Both the ratchet 13 and the coil spring 14 rotate within the second rotating groove 15, thus restricting their positions. A first baffle 16 and a second baffle 17 are rotatably connected to one end of the fixed platform 1. The first baffle 16 is movably engaged with the ratchet 13, and the second baffle 17 is located at the position of the first baffle 16. At the upper end, the first baffle 16 and the second baffle 17 work together to restrict the ratchet 13 to rotate in one direction. The trainee can move the second connecting rod 19 and the first connecting rod 18 by lifting the lever 20, and then move the second baffle 17. The first baffle 16 is engaged with the ratchet 13, so that the second baffle 17 loses its restriction on the first baffle 16. Thus, the ratchet 13 and the rotating shaft 12 are reset and rotated with the help of the coil spring 14, and the transmission line 11 is quickly wound up, which is convenient to use and easy to operate. The movement direction of the limiting rod 22 is restricted by the second limiting groove 8, which in turn restricts the movement direction of the second connecting rod 19. Before the operator can lift the lever 20, he / she must first rotate the limiting rod 22 from the second limiting groove 8 to the third rotating groove 21 through the second connecting rod 19 before the lever 20 can be lifted, which improves the positional stability of the second baffle 17.
