Description

Technical Field

[0001] The utility model belongs to the technical field of hydrogen storage, and in particular relates to a hydrogen storage device with stable pressure. Background Art

[0002] Hydrogen is a colorless gas with a lower density than air. Since hydrogen is insoluble in water, it can be collected by the water-discharge gas collection method. In addition, at a standard atmospheric pressure and a temperature of -252.87°C, hydrogen can be converted into a colorless liquid. At room temperature, the properties of hydrogen are very stable and it is not easy to react chemically with other substances.

[0003] At present, when hydrogen is stored in hydrogen storage tanks, most of the factories that store hydrogen require the staff to first fix and limit the hydrogen storage tanks to ensure the stability of the storage tanks during the filling process to prevent the storage tanks from shaking and affecting the filling. Then, the filling pipe and the storage tanks are connected for filling. After the filling is completed, the storage tanks are unfixed and fixed, and the storage tanks are taken out and placed. The above operations are relatively cumbersome, mainly because the hydrogen storage tanks cannot be fixed at the same time during the filling process, which increases the working time and reduces the working efficiency. Therefore, it is necessary to provide a new pressure-stable hydrogen storage equipment to solve the above technical problems. Utility Model Content

After the sliding plate 53 stops moving, the gas inside the hydrogen storage tank 3 will not escape, thereby sealing the hydrogen storage tank 3.

[0032] Preferably, the outer wall of the upper end of the first slide plate 21 is located on one side of the first socket 26 and is provided with a second socket 27 that cooperates with the fixing component 6. The fixing component 6 can be movably inserted through the second socket 27. The fixing component 6 includes a fixing rod 61, a fixing disk 62, a cone disk 63, a hemisphere 64, a cone groove 65, and a second spring 66.

[0033] Preferably, one end of the first tooth plate 7 and the second tooth plate 9 respectively meshing with the first gear 8 are arranged parallel to each other.

[0034] Preferably, the inflation component 11 includes an inflation port 111 and a push rod 112 , the inflation port 111 is provided on the outer wall of one end of the second slide plate 10 close to the first slide plate 21 , the push rod 112 is fixedly provided on the inner wall of the inflation port 111 , and the air inlet 51 can be slidably inserted into the inner wall of the inflation port 111 .

[0039] The working principle of a pressure-stable hydrogen storage device provided by the utility model is as follows:

[0040] The first step: first, the hydrogen storage tank 3 that needs to store gas is passed through the positioning rod 19, and the staff can quickly place the hydrogen storage tank 3 on the upper end of the support bracket 24, and push the first slide plate 21 toward the second slide plate 10, and the first slide plate 21 slides along the slide column 18. Since the third tooth plate 15 and the fourth tooth plate 16 are respectively engaged with the second gear 14, the fourth tooth plate 16 drives the second gear 14 to rotate, and the second gear 14 drives the third tooth plate 15 to move, so that the third tooth plate 15 drives the second slide plate 10 to approach the first slide plate 21 along the slide column 18, and the third tooth plate 15 will pass through the first plug hole 25, and the fourth tooth plate 16 will pass through the second plug hole 17. In the process of the second slide plate 10 and the first slide plate 21 approaching each other, the first tooth plate 7 and the second tooth plate 9 are respectively engaged with the first gear 8, so that the first gear 8 can drive the first tooth plate 7 to move. Since the sliding sleeve 23 can slide along the adjusting rod 22, and the support bracket 24 is movably inserted at the upper end of the first slide plate 21, The first toothed plate 7 drives the sliding sleeve 23 to slide along the adjusting rod 22 toward the first slide plate 21. At this time, the support bracket 24 drives the hydrogen storage tank 3 to slide along the first slide plate 21. When the second slide plate 10 and the first slide plate 21 approach each other, the air inlet 51 passes through the first socket 26 and the air inlet 51 is inserted into the charging port 111. Similarly, the fixing component 6 passes through the second socket 27. When the air inlet 51 is inserted into the charging port 111 and slides slowly in the charging port 111, the semi-closed portion 26 is moved to the charging port 111. The ball 64 continues to approach the inclined surface 124, and the inclined surface can slide along the hemisphere 64, so that the inclined surface 124 drives the sliding rod 122 to slide upward along the straight plate 121 and continuously stretches the third spring 123. When the inclined surface 124 slides along the curved surface of the hemisphere 64 and leaves the hemisphere 64, under the reverse force of the third spring 123, the sliding rod 122 is inserted into the gap formed by the curved surface and the fixed plate 62, and at this time, the second slide plate 10 and the first slide plate 21 stop approaching each other and the inflation operation is performed.

[0041] Step 2: When the air inlet 51 and the charging port 111 are docked, the air inlet 51 continuously slides along the inner wall of the charging port 111. At this time, the push rod 112 pushes the sliding plate 53 to slide toward the inner wall of the air inlet 51. When the sliding plate 53 slides, the first spring 54 is continuously compressed. When the sliding plate 53 slides to pass through the vent hole 55, the hydrogen storage tank 3 is inflated. The hydrogen enters the hydrogen storage tank 3 along the vent hole 55, and the pressure change inside the hydrogen storage tank 3 is observed by observing the pressure gauge 4. When the gas inside the hydrogen storage tank 3 reaches the amount of hydrogen that needs to be stored, the gas supply to the hydrogen storage tank 3 is stopped, and at this time, the air inlet 51 and the gas charging port 111 are separated from each other. Under the action of the reverse elastic force of the first spring 54 and the internal pressure of the hydrogen storage tank 3, the sliding plate 53 can be pushed to slide toward the outer opening of the air inlet 51 until the sliding plate 53 is separated from the vent hole 55, and under the action of the limiting block 56, the sliding plate 53 can be prevented from sliding out. After the sliding plate 53 stops moving, the gas inside the hydrogen storage tank 3 will not escape, thereby The tank 3 is sealed. After the inflation is completed, the first slide plate 21 is pushed toward the second slide plate 10 again. At this time, the slide bar 122 moves toward the cone disk 63, and the inclined surface 124 slides along the cone disk 63 until the inclined surface slides to another curved surface of the cone disk 63. At this time, the first slide plate 21 is pushed away from the second slide plate 10, and the slide bar 122 pushes the cone disk 63 to compress the second spring 66, and the curved surface of the cone disk 63 close to the cone groove 65 slides into the cone groove 65. At this time, the first slide plate 21 is continued to be pushed away from the second slide plate 10, and the inclined surface 124 drives the slide bar 122 away from the hemisphere 64.
