[0025] Example: See Figures 1 to 5 As shown, a teaching test box for a new energy power generation system includes a lower shell 1 and an upper shell 2. The rear sides of the lower shell 1 and the upper shell 2 are hinged together by several hinges. Several longitudinal telescopic support rods 4 are inserted inside the lower shell 1. The rear end of the telescopic support rods 4 extends out of the lower shell 1 and is fixed with a horizontally upright support plate 5. The lower end face of the support plate 5 is flush with the lower end face of the lower shell 1.
[0026] A transverse pad 6 is fixed to the rear end face of the lower housing 1. After the lower housing 1 is flipped to stand upright, the pad 6 abuts against the telescopic support rod 4. An oblique support 3 is provided on one side of the lower housing 1 and the upper housing 2. The oblique support 3 includes an upper connecting rod 31 and a lower connecting rod 32 that are obliquely placed and parallel to each other. The lower end of the lower connecting rod 32 is hinged to the lower housing 1 by a pin, and the upper end is hinged to the lower end of the upper connecting rod 31 by a pin. The upper end of the upper connecting rod 31 is hinged to the upper housing 2 by a pin.
[0027] The upper casing 2 is fixedly connected to a mounting base plate 14 at its upper part and a horizontally arranged hydrogen cylinder 10 at its lower part. A pressure reducing valve 9 and a transparent water storage tank 8 are fixedly fixed on one side of the mounting base plate 14, and a fuel cell stack 7, a terminal block 11, and a lamp holder 13 are fixedly connected on the other side. The electrodes on the fuel cell stack 7 are connected to wires, and the fuel cell stack 7 is electrically connected to the input end of the terminal block 11 through the wires. A cooling fan 12 is fixedly connected to the side wall of the upper casing 2, facing the fuel cell stack 7. Several air inlets opposite to the cooling fan 12 are formed on the side wall of the upper casing 2. The lamp holder 13 and the cooling fan 12 are electrically connected to the output end of the terminal block 11 through wires.
[0028] The outlet of the hydrogen cylinder 10 is connected to the hydrogen inlet of the fuel cell stack 7 via a hydrogen inlet pipe. The pressure reducing valve 9 is installed on the hydrogen inlet pipe. The outlet of the fuel cell stack 7 is connected to the transparent water storage tank 8 via a drain pipe.
[0029] The length of the telescopic support rod 4 is less than the length of the lower housing 1. The support plate 5 on the telescopic support rod 4 is made of magnetic material, and the pad 6 is made of permanent magnet material.
[0030] When the upper casing 2 is flipped to an upright position, the center distance from the front end face of the pad 6 to the center distance from the hinge core is equal to the center distance from the upper end face of the support plate 5 to the center distance from the hinge core. Then, when the upper casing 2 is flipped horizontally and closed with the lower casing 1, the support plate 5 can be pushed forward to allow the telescopic support rod 4 to retract into the lower casing 1. When the support plate 5 abuts against the rear end face of the lower casing 1, the front end face of the pad 6 flips and becomes the lower end face that contacts the upper end face of the support plate 5, so that the support plate 5 is sucked against the pad 6, thereby positioning the position of the support plate 5.
[0031] The thickness of the support plate 5 is equal to the thickness of the pad plate 6. When the lower shell 1 and the upper shell 2 are closed, the rear end face of the support plate 5 and the rear end face of the pad plate 6 are flush.
[0032] A transverse partition 16 is inserted and fixed inside the upper casing 2 between the mounting base plate 14 and the hydrogen cylinder 10. A longitudinal partition 15 is inserted and fixed inside the upper casing 2 between the transparent water storage tank 8 and the fuel cell stack 7. A transparent protective plate is inserted and fixed inside the upper casing 2 on one side of the longitudinal partition 15. The fuel cell stack 7, the terminal block 11, and the lamp holder 13 are located inside the transparent protective plate. A small lamp is fixedly connected to the lamp holder 13. The fuel cell stack 7, the terminal block 11, and the lamp holder 13 are isolated by the transparent protective plate for greater safety.
[0033] The longitudinal partition 15 has several exhaust holes formed on it, which are opposite to the cooling fan 12. Several gas cylinder supports 17 are inserted into the upper shell 2 on the lower side of the transverse partition 16. The hydrogen cylinder 10 is placed on the gas cylinder support 17. A longitudinally arranged and arc-shaped pressure plate 18 is abutted on the outer wall of the middle part of the hydrogen cylinder 10. The two ends of the pressure plate 18 are respectively fixed in the upper shell 2.
[0034] The hydrogen cylinder 10 is equipped with a cylinder valve at its outlet, and the pressure reducing valve 9 is equipped with a manual pressure adjusting knob.
[0035] The transparent water storage tank 8 includes a transparent box body 81 fixedly connected inside the upper shell 2. A sealing cover 82 is fixedly connected to the top of the transparent box body 81. A horizontal vent pipe 83 is inserted into the bottom of the transparent box body 81. One end of the vent pipe 83 is formed with a cap, and the other end is inserted with a horizontal drain pipe 86. The end of the drain pipe 86 passes through the transparent box body 81 and is formed with a pagoda connector 863. A spring 87 is inserted into the vent pipe 83. One end of the spring 87 presses against the cap of the vent pipe 83, and the other end presses against the drain pipe 86. A limiting ring 861 is formed on the outer wall of the drain pipe 86, and the limiting ring 861 presses against the inner wall of the transparent box body 81. A drain inlet 862 is formed on the wall of the drain pipe 86 on the outer side of the transparent box body 81.
[0036] An inclined guide plate 85 is inserted and fixed to the upper part of the transparent box 81. A vertical exhaust pipe 84 is inserted and fixed to the middle part of the guide plate 85. The upper end of the exhaust pipe 84 is close to the upper box shell 2, and the lower end is fixed to the vent pipe 83 and connected to the vent pipe 83.
[0037] A sealing gasket 88 is inserted into the drain pipe 86, and the sealing gasket 88 is clamped between the limiting ring 861 and the inner wall of the transparent box 81; a sealing ring 89 is inserted and fixed on the inner wall of the vent pipe 83, and the sealing ring 89 is pressed against the outer wall of the drain pipe 86; the drain pipe 86 can be pressed so that the drain inlet 862 on the drain pipe 86 can enter the transparent box 81;
[0038] When the fuel cell stack 7 generates electricity, the hydrogen and oxygen in the air can react inside the fuel cell stack 7 to produce water, which flows into the transparent water tank 8. When water enters the transparent water tank 8, its internal space needs to be vented. The air in the transparent water tank 8 is discharged from the exhaust pipe 84, the vent pipe 83, and the drain pipe 86. When the water tank needs to be drained, a hose can be connected to the pagoda connector 863 of the drain pipe 86, and then the drain pipe 86 is driven back into the transparent water tank 8, so that the drain inlet 862 on the drain pipe 86 enters the transparent water tank 8. The water enters from the drain inlet 862 of the drain pipe 86 and flows out along the drain pipe 86 and the hose to achieve drainage. Of course, there is a situation where the transparent water tank 8 is not completely drained, but due to the layout structure of the exhaust pipe 84 and the guide plate 85, no matter how the test chamber is placed, the small amount of water in the transparent water tank 8 is not easy to enter from the inlet of the exhaust pipe 84.
[0039] Working principle: This structure is a teaching test box for a new energy power generation system. The outer box of the teaching test box is also a suitcase structure, which is convenient to carry. When used for teaching, by pulling back the support plate 5, the upper shell 2 is opened and flipped to stand upright. The upper shell 2 is supported on the telescopic support rod 4, and the upper connecting rod 31 and the lower connecting rod 32 are flipped to be parallel, which can effectively realize the upper shell 2 to be displayed in an upright state.
[0040] Meanwhile, the hydrogen cylinder 10, pressure reducing valve 9, fuel cell stack 7, terminal block 11, lamp holder 13, cooling fan 12, and transparent water tank 8 are all arranged inside the upper shell 2. By opening the gas cylinder valve on the hydrogen cylinder 10 and adjusting the pressure reducing valve 9, the hydrogen in the hydrogen cylinder 10 flows into the fuel cell stack 7, where it reacts with oxygen in the air to generate electricity. The electricity generated can supply the cooling fan 12 and the lamp holder 13, enabling the small light bulb on the lamp holder 13 to light up. At the same time, the cooling fan 12 works, generating airflow to cool the fuel cell stack 7 and replenish oxygen; while the water generated by the fuel cell stack 7 flows into the transparent water tank 8.

Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the invention; therefore, the scope of protection of the invention should be as set forth in the claims.
