[0028] As Figure 1 and Figure 2 shown, a solid-state hydrogen storage device provided by an embodiment of the present utility model includes a support frame 1, an inner cylinder 2, an outer cylinder 3, a second temperature sensor 18, a wire 13, and a sealing assembly; the inner cylinder 2 and the outer cylinder 3 are installed on the support frame 1, the outer cylinder 3 is sleeved on the inner cylinder 2, a liquid inlet 8 and a liquid outlet 9 are provided on the outer cylinder 3, and a liquid storage cavity 15 is formed between the inner cylinder 2 and the outer cylinder 3; as Figure 3 shown, the second temperature sensor 18 is installed on the inner cylinder 2 and is located in the liquid storage cavity 15; the second temperature sensor 18 is connected to the wire 13, and the wire 13 penetrates through the outer cylinder 3 and is used to be connected to a controller; a sealing assembly is provided between the wire 13 and the outer cylinder 3.

[0029] In this embodiment, as Figure 2As shown in the figure, the inner cylinder 2 and the outer cylinder 3 are installed on the support frame 1.

Or a liquid circulation device is adopted to circulate and supply heated liquid to the liquid storage cavity 15 from the liquid inlet 8 and the liquid outlet 9. The second temperature sensor 18 detects the liquid temperature in the liquid storage cavity 15 and transmits the detected liquid temperature to the controller, so that the controller can control the timing of the heated liquid entering and leaving the liquid storage cavity 15. For example, the controller controls the liquid circulation device to stop working when the temperature is high and continue to work when the temperature is low, etc., to avoid overheating the inner cylinder 2, release hydrogen appropriately, and reduce hydrogen waste. In addition, the second temperature sensor 18 is connected to the controller through the wire 13. In order to prevent the outer cylinder 3 from leaking, a sealing assembly is arranged between the wire 13 and the outer cylinder 3. The sealing assembly can also be arranged at the top of the outer cylinder 3 to further reduce the risk of liquid leakage and also reduce the heat dissipation of the heated liquid and improve the heat utilization rate.

[0030] Optionally, the sealing assembly includes a flange 4, a sealing plug 5, a gasket 6 and a flange seat 7. The flange seat 7 is installed on the outer cylinder 3.

The sealing plug 5 seals the gap between the wire 13 and the flange 4, and the gasket 6 seals the gap between the flange 4 and the flange seat 7, so as to ensure the sealing effect of the liquid storage cavity and prevent the liquid in the liquid storage cavity from leaking around the wire 13.

[0033] Optionally, asFigure 4 and Figure 5 As shown in Figure 5 , the sealing plug 5 includes a sealing sleeve 50, a first fixing portion 52, and a second fixing portion 53. The sealing sleeve 50 is sleeved on the wire 13. The first fixing portion 52 and the second fixing portion 53 are arranged on the outer peripheral surface of the sealing sleeve 50. A clamping groove 54 is formed between the first fixing portion 52 and the second fixing portion 53. The inner wall of the second through hole on the flange 4 is located in the clamping groove 54.

[0034] Specifically, the sealing sleeve 50 wraps multiple wires 13. The first fixing portion 52 and the second fixing portion 53 jointly clamp the flange 4. During use, as shown in Figure 4 , the second fixing portion 53 in the sealing plug 5 can be inserted into the first through hole through the second through hole on the flange 4, so that the inner wall of the flange 4 is located in the clamping groove 54. At this time, the first fixing portion 52 and the second fixing portion 53 are respectively in close contact with the upper surface and the lower surface of the flange 4, avoiding the leakage of the liquid in the liquid storage cavity from between the sealing plug 5 and the flange 4. The sealing plug 5 has a certain elasticity and can be made of materials such as silica gel or rubber. The sealing sleeve 50 squeezes multiple wires 13, making the multiple wires 13 fit together. The sealing sleeve 50 wraps and fills the gaps around the wires 13, so that there is almost no gap between the multiple wires 13; or the sealing sleeve 50 completely wraps a single wire 13, and there is no gap around the wire 13. Figure 4 As shown in Figure 4 , the second fixing portion 53 in the sealing plug 5 can be inserted into the first through hole through the second through hole on the flange 4, so that the inner wall of the flange 4 is located in the clamping groove 54. At this time, the first fixing portion 52 and the second fixing portion 53 are respectively in close contact with the upper surface and the lower surface of the flange 4, avoiding the leakage of the liquid in the liquid storage cavity from between the sealing plug 5 and the flange 4. The sealing plug 5 has a certain elasticity and can be made of materials such as silica gel or rubber. The sealing sleeve 50 squeezes multiple wires 13, making the multiple wires 13 fit together. The sealing sleeve 50 wraps and fills the gaps around the wires 13, so that there is almost no gap between the multiple wires 13; or the sealing sleeve 50 completely wraps a single wire 13, and there is no gap around the wire 13.

[0035] Optionally, as shown in Figure 4 , the sealing plug 5 further includes a reinforcing portion 51, and the reinforcing portion 51 is arranged on the sealing sleeve 50 outside the first through hole and the second through hole. Figure 4 As shown in Figure 4 , the sealing plug 5 further includes a reinforcing portion 51, and the reinforcing portion 51 is arranged on the sealing sleeve 50 outside the first through hole and the second through hole.

[0036] Specifically, the reinforcing portion 51 is arranged around one end of the sealing sleeve 50 that leaks out of the outer cylinder 3. On the one hand, it can strengthen the wrapping force of the sealing sleeve 50 on multiple wires 13. On the other hand, it can also strengthen the supporting force at the upper end of the sealing plug 5, making the upper end of the sealing plug 5 keep upright, avoiding the inclination of the sealing plug 5 caused by the pulling of the wires 13 and reducing the sealing effect.

[0037] Optionally, as shown in Figure 4 and Figure 5 , the second fixing portion 53 is in contact with one end of the flange 4 close to the first through hole, the first fixing portion 52 is in contact with one end of the flange 4 away from the first through hole, and a plurality of grooves 55 are arranged on the first fixing portion 52.

[0038] Specifically, a plurality of planes can be arranged in the circumferential direction of the first fixing part 52 and the second fixing part 53, so that the cross-sectional shapes of the first fixing part 52 and the second fixing part 53 are similar to polygonal shapes, which can enhance the strength of the first fixing part 52 and the second fixing part 53 and are not easily deformed in the circumferential direction. The first fixing part 52 is located on the upper end surface of the flange 4, and a plurality of grooves 55 are arranged on the first fixing part 52, so that the first fixing part 52 is easily deformed axially. At this time, the height of the clamping groove 54 can be set slightly smaller than the thickness of the flange 4, so that the first fixing part 52 generates a slight deformation, ensuring that the first fixing part 52 and the second fixing part 53 are completely and tightly attached to the upper and lower surfaces of the flange 4 and ensuring the sealing effect.

[0039] Optionally, as Figure 2 shown, the solid-state hydrogen storage device further includes a first temperature sensor 14, and the first temperature sensor 14 is installed at one end of the inner cylinder 2; the temperature detection end of the first temperature sensor 14 is located inside the inner cylinder 2 and is used to detect the temperature of the solid material in the inner cylinder 2; the wiring end of the first temperature sensor 14 is located outside the inner cylinder 2 and is used to be connected to the controller.

[0040] In this embodiment, the first temperature sensor 14 can detect the temperature of the solid material in the inner cylinder 2, accurately monitor the temperature of the solid material, and thus control the temperature and flow rate of the liquid entering and exiting the liquid storage cavity 15 through the controller. For example, if it is desired to slowly release hydrogen, it is necessary to control the temperature of the solid material not to be too high. When the temperature of the solid material is high, it is necessary to control the temperature of the liquid entering the liquid storage cavity 15 to be low. If the liquid circulates in and out of the liquid storage cavity 15, the flow rate of the liquid can also be reduced, so that the replacement speed of the liquid in the liquid storage cavity 15 is reduced.

[0042] Specifically, the heat conducting member is installed on the inner cylinder 2, increasing the area in contact with the high-temperature liquid, transferring the temperature of the high-temperature liquid in the liquid storage cavity 15 to the inner cylinder 2, and then to the inside of the inner cylinder 2, improving the heating efficiency of the solid material.

[0044] Optionally, as Figure 2 and Figure 3 shown, the heat conducting member includes a second heat conducting plate 17. As Figure 3 shown, the second heat conducting plate 17 is a spiral heat conducting plate, and the second heat conducting plate 17 is installed on the outer wall of the inner cylinder 2.

As Figure 3 shown, the first heat conducting plate 16 and the second heat conducting plate 17 can be installed on the inner cylinder 2 at the same time. The second heat conducting plate 17 passes through the first heat conducting plate 16 to increase the contact area with the high-temperature liquid in both the axial and circumferential directions, maximize the utilization of the heat of the high-temperature liquid, and improve the hydrogen release speed of the device.

[0046] Optionally, as Figure 2 shown, the solid hydrogen storage device further includes an air guide pipe 12 and an intake air filter screen 10. The air guide pipe 12 is installed inside the inner cylinder 2. One end of the air guide pipe 12 is communicated with the intake port 11 at one end of the inner cylinder 2. An intake air filter screen 10 is installed at one end of the air guide pipe 12, and the other end of the air guide pipe 12 is installed on the inner wall of the inner cylinder 2 to prevent the air guide pipe 12 from shaking inside the inner cylinder 2 and improve the stability of the air guide pipe 12.

[0047] In this embodiment, the inner cylinder 2 is filled with a solid material. Hydrogen is introduced into the air guide pipe 12 from the intake port 11. The air guide pipe 12 transports the hydrogen to the inside of the inner cylinder 2. Under appropriate temperature and pressure, the hydrogen is adsorbed by the solid material, thereby completing the solid-state storage of hydrogen. The intake air filter screen 10 filters the incoming hydrogen to prevent other solid impurities in the hydrogen from entering the inner cylinder 2. In addition, a sleeve is installed inside the inner cylinder 2, and the sleeve is sleeved on the air guide pipe 12. The sleeve supports the air guide pipe 12 so that one end of the air guide pipe 12 is aligned with the intake port 11. In addition, the sleeve also seals the solid material in the inner cylinder 2 to prevent the solid material from leaking.
