Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen fuel cells, in particular to a hydrogen battery module with pressure maintenance. Background Art

[0002] A hydrogen fuel cell is a device that generates electricity by reacting hydrogen and oxygen under the action of a catalyst. A hydrogen battery module with a pressure-maintaining function is a device that can maintain a constant output pressure in a hydrogen supply system. A hydrogen battery module with a pressure-maintaining function can ensure the stability and safety of hydrogen supply, thereby improving the efficiency and reliability of the fuel cell system.

[0003] During the use of hydrogen batteries, the pressure inside the hydrogen storage tank will gradually increase. Since the existing hydrogen battery module lacks a pressure-maintaining structure, the pressure inside the hydrogen storage tank cannot be reduced, which will further pose a greater safety hazard. In addition, when the existing hydrogen battery module is in use, due to the lack of a hydrogen leakage detection device, the user cannot promptly detect hydrogen leakage during the operation of the hydrogen battery module, which will further pose a greater safety hazard. Therefore, it is necessary to provide a hydrogen battery module with pressure maintenance to solve the above technical problems. Utility Model Content

[0006] Preferably, the outer sleeve of the movable rod is provided with a sealing sleeve, and the sealing sleeve is fixedly connected to the outer wall of the top end of the hydrogen storage tank. The outer wall of the top end of the hydrogen storage tank is provided with a sealing ring.

[0007] Preferably, the switch one corresponds to the switch controlling the water pump, and the switch two corresponds to the switch controlling the water suction pump.

[0008] Preferably, a plurality of evenly distributed partitions are installed inside the detection box, and a group of hydrogen detection devices are installed between each group of partitions. The use of partitions can isolate the interior of the detection box into a plurality of detection chambers, further facilitating the determination of the approximate location of the hydrogen storage tank leak.

[0009] Preferably, a clamping groove is provided inside the mounting block, and a clamping block is rotatably installed inside the clamping groove.

During the movement of the moving block, the movable rod also begins to move outward. When the pressure inside the hydrogen storage tank is high, the two sets of movable rods will start to squeeze and press switch one and switch two respectively. As switch one and switch two are pressed and opened, the water pump and the water suction pump in the water tank start to start at the same time. In one step, water will continuously pass through the water pipe wrapped around the outside of the hydrogen storage tank to complete the operation of cooling the hydrogen storage tank; in addition, a plurality of hydrogen detection devices are installed inside the detection box at the upper end of the sealed box.

When an obvious change in the color of the hydrogen detection tape is observed through the detection box, it can be determined that the hydrogen storage tank has leaked and needs to be repaired in time. At the same time, the specific leakage position of the hydrogen storage tank can be roughly determined according to the position of the discolored hydrogen detection tape inside the detection box, which effectively avoids accidents and ensures the safety of users.

[0030] Specifically, a sealing sleeve 12 is provided on the outside of the movable rod 11, and the sealing sleeve 12 is fixedly connected to the outer wall of the top end of the hydrogen storage tank 5. A sealing ring 13 is provided on the outer wall of the top end of the hydrogen storage tank 5. The use of the sealing sleeve 12 and the sealing ring 13 can effectively increase the sealing performance inside the hydrogen storage tank 5 and effectively improve the stability of the hydrogen battery.

[0031] Specifically, switch 1 20 corresponds to the switch for controlling the water pump 18, and switch 2 21 corresponds to the switch for controlling the water suction pump 19. By turning on switch 1 20 and switch 2 21, the water pump 18 and the water suction pump 19 can be controlled to transport water, which can further effectively reduce the temperature inside the hydrogen storage tank 5, ensuring that the hydrogen battery can work normally.

[0032] Specifically, a plurality of evenly distributed partitions are installed inside the detection box 22, and a group of hydrogen detection devices are installed between each group of partitions.

[0035] Specifically, a plurality of replacement ports are evenly arranged on the outer wall of the upper end of the detection box 22, and the position of each replacement port corresponds to the sealing cover 27. The setting of the replacement port enables the hydrogen detection tape 26 to be taken out through the replacement port, which facilitates the timely replacement of the hydrogen detection tape 26 and ensures the normal operation of the detection device inside the detection box 22.

[0036] Specifically, the sealing box 3 and the detection box 22 are both made of transparent materials. The selection of transparent materials is conducive to the user to observe the phenomena inside the sealing box 3 and the detection box 22 in time, which is conducive to dealing with emergencies.

[0037] Working principle: When the pressure inside the hydrogen storage tank 5 increases due to the increase in temperature, the moving block 10 will slowly move outward inside the hydrogen storage tank 5, thereby reducing the pressure inside the hydrogen storage tank 5. During the movement of the moving block 10, the movable rod 11 also starts to move outward. When the pressure inside the hydrogen storage tank 5 is relatively high, the two groups of movable rods 11 will start to squeeze and press the switch 1 20 and the switch 2 21 respectively. As the switch 1 20 and the switch 2 21 are pressed and opened, the water pump 18 and the water suction pump 19 in the water tank 4 start to start at the same time, further causing water to continuously pass through the water pipe 17 wrapped around the outside of the hydrogen storage tank 5. , complete the operation of cooling the hydrogen storage tank 5. When the hydrogen storage tank 5 begins to leak hydrogen, the hydrogen will enter the detection box 22 through the leakage hole at the upper end of the sealing box 3, and then cause the hydrogen detection tape 26 inside the detection box 22 to change color. When an obvious change in the color of the hydrogen detection tape 26 is observed through the detection box 22, it can be determined that the hydrogen storage tank 5 has a leak and needs to be repaired in time. At the same time, the specific leakage position of the hydrogen storage tank 5 can be roughly determined according to the position of the discolored hydrogen detection tape 26 inside the detection box 22. This is the entire working process of a hydrogen battery module with pressure maintenance.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
