Description

TECHNICAL FIELD

[0001] The present application relates to the hydrogen storage system technical field, especially to a kind of anti-sunlight hydrogen storage system. BACKGROUND

[0002] In order to reduce the waste of electric energy, the State Grid uses the surplus electric energy to electrolyze alkali water to produce hydrogen, and stores the hydrogen in hydrogen storage tanks. During the peak electricity consumption, hydrogen fuel cells use the hydrogen to generate electricity for people to use.

[0003] The existing hydrogen production system includes an electrolysis tank, a hydrogen storage tank, and a pipe network connecting the hydrogen storage tank and the electrolysis tank. In order to ensure air circulation and for safety reasons, the hydrogen storage tank and the pipe network are installed in an open environment, which directly exposes them to sunlight and rain. This accelerates the aging of the hydrogen storage tank and the pipe network, and the high temperature of the sunlight in hot weather increases the temperature of the hydrogen storage tank, which in turn increases the pressure of the hydrogen in the hydrogen storage tank, causing safety hazards. SUMMARY

[0004] The present application proposes an anti-sunlight hydrogen storage system to solve the problem of the existing hydrogen production system not being able to shade the hydrogen storage tank, which causes the pressure of the hydrogen storage tank to increase and leads to safety hazards.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] An anti-sunlight hydrogen storage system includes an electrolysis tank and a hydrogen storage tank. The electrolysis tank is connected to an air compressor through a first pipe. The air compressor is connected to the hydrogen storage tank through several second pipes. A hydrogen discharge pipe extends upward and is fixedly connected to the second pipe. A valve is arranged at the lower end of the hydrogen discharge pipe. Two upright columns are arranged on the side of the hydrogen storage tank away from the hydrogen discharge pipe. The upright columns are fixed to the ground. Sliding rails are fixedly connected to the upper ends of the upright columns near the hydrogen discharge pipe. The sliding rails are parallel to each other. The sliding rails and the upper end of the hydrogen discharge pipe are fixedly connected. A winding roller is rotatably connected to the side of the upright column near the hydrogen discharge pipe. A sunshade cloth is wound around the winding roller. The sunshade cloth is arranged above the hydrogen storage tank. A support rod is connected to the end of the sunshade cloth away from the winding roller. The two ends of the support rod are slidably connected to the sliding rails. The support rod is connected to the hydrogen discharge pipe through a connecting piece. A first spring is arranged at the upper end of the upright column to drive the winding roller to roll up the sunshade cloth.

[0007] The sunshade cloth is connected to the support rod through the connecting piece and the hydrogen discharge pipe, and the other end of the sunshade cloth is wound on the winding roller. The first spring applies a torsion force to the winding roller, so that the sunshade cloth is always straightened. When the electrolytic tank needs to be emptied of hydrogen during shutdown or maintenance, the hydrogen in the hydrogen storage tank is discharged through the hydrogen discharge pipe, so as to prevent safety accidents. When discharging hydrogen, the valve is opened, and the hydrogen storage tank discharges hydrogen into the atmosphere through the second pipe and the hydrogen discharge pipe. The hydrogen discharge pipe extends upward, so as to prevent hydrogen from gathering near the ground. In order to prevent the local hydrogen density from rising when hydrogen diffuses to the lower side of the sunshade cloth, the connecting piece is automatically disconnected from the support rod during hydrogen discharge. Under the action of the first spring, the winding roller winds the sunshade cloth, the sunshade cloth is wound on the winding roller, and the support rod moves along the sliding rail to the winding roller.

The first pull line passes through the reversing wheel and is connected with the winch.

[0011] Further, the upper end of the hydrogen discharge pipe is provided with a sliding groove near one side of the stand, the connecting piece comprises a sliding sleeve slidably connected in the hydrogen discharge pipe, the sliding sleeve and the hydrogen discharge pipe are connected through a second spring, one side of the sliding sleeve is fixedly connected with a pull rod, the pull rod passes through the sliding groove and abuts against the lower end of the sliding groove, the end of the pull rod away from the sliding sleeve is provided with a downward hook, the support rod is provided with a slot with an opening facing the hook, the lower side of the slot is provided with a matching groove with an upward opening, the end of the pull rod away from the sliding sleeve is located in the slot, and the hook is located in the matching groove.

[0022] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] See Figures 1 to 7An anti-sun exposure hydrogen storage system includes an electrolysis tank 11 and a hydrogen storage tank 12. The electrolysis tank 11 is connected to an air compressor 14 via a first pipe 13. The air compressor 14 is connected to the hydrogen storage tank 12 via several second pipes 15. An upwardly extending hydrogen discharge pipe 16 is fixedly connected to each of the second pipes 15. A valve 161 is installed at the lower end of the hydrogen discharge pipe 16. Two columns 17 are installed on the side of the hydrogen storage tank 12 away from the hydrogen discharge pipe 16. The columns 17 are fixed to the ground. A slide rail 18 is fixedly connected to the upper end of each column 17 near the hydrogen discharge pipe 16. The slide rails 18 are parallel to each other. The upper ends of the slide rail 18 and the hydrogen discharge pipe 16 are fixedly connected. A winding roller 171 is rotatably connected to the side of the column 17 near the hydrogen discharge pipe 16. The winding roller 171 is wound with a sunshade cloth 172. The sunshade cloth 172 is placed above the hydrogen storage tank 12. A support rod 173 is connected to the end of the sunshade cloth 172 away from the winding roller 171. The two ends of the support rod 173 are slidably connected to the slide rail 18. The support rod 173 is connected to the hydrogen discharge pipe 16 through a connector 174. A first spring 175 is provided at the upper end of the column 17 for driving the winding roller 171 to wind up the sunshade cloth 172.

[0024] The above-described configuration provides shade for the hydrogen storage tank 12, thereby cooling it during hot weather and improving the safety of the hydrogen storage system. Specifically, the electrolyzer 11 electrolyzes alkaline water to generate hydrogen gas. The hydrogen gas travels through the first pipe 13 to the air compressor 14, where it is compressed and then enters the hydrogen storage tank 12 through the second pipe 15. The hydrogen storage tank 12 is used to store hydrogen gas. A shading cloth 172 is positioned above the hydrogen storage tank 12 to provide shade. One end of the shading cloth 172 is connected via a support rod 173, a connector 174, and a hydrogen discharge pipe 16. The other end of the shading cloth 172 is wound around a winding roller 171. A first spring 175 applies torque to the winding roller 171, ensuring that the shading cloth 172 remains taut. During shutdown or maintenance, this application requires the hydrogen in the hydrogen storage tank 12 to be emptied via the hydrogen venting pipe 16 to prevent safety accidents. During venting, valve 161 is opened, and the hydrogen storage tank 12 releases the hydrogen into the atmosphere through the second pipe 15 and the hydrogen venting pipe 16. The hydrogen venting pipe 16 extends upwards to prevent hydrogen from accumulating near the ground. During venting, to prevent hydrogen from diffusing to the underside of the sunshade cloth 172 and causing a local increase in hydrogen density, the connector 174 automatically disengages from the support rod 173 during venting. Under the action of the first spring 175, the winding roller 171 winds up the sunshade cloth 172, and the support rod 173 moves along the slide rail 18 to the winding roller 171.

[0025] As one implementation, a connecting plate 176 is fixedly connected to the upper end of the column 17, and a rotating shaft 1711 is fixedly connected to both ends of the winding roller 171. The rotating shaft 1711 passes through the connecting plate 176 and is rotatably connected to the connecting plate 176.

[0026] With the above configuration, the column 17 is rotatably connected via the connecting plate 176, the rotating shaft 1711, and the winding roller 171.

[0027] In one implementation, the first spring 175 is sleeved on the rotating shaft 1711, with one end of the first spring 175 connected to the rotating shaft 1711 and the other end of the first spring 175 connected to the connecting plate 176.

[0028] As one implementation, the two ends of the support rod 173 are connected to the first pull wire 1731, the upper end of the hydrogen discharge pipe 16 is rotatably connected to the reversing wheel 162 on the side away from the column 17, and a winch 163 is set below the reversing wheel 162. The winch 163 is set on the ground, and the first pull wire 1731 passes through the reversing wheel 162 and is connected to the winch 163.

[0029] The above setup facilitates the repositioning of the shading cloth 172 above the hydrogen storage tank 12 to provide shade. Specifically, the winch 163 winds the first pull cable 1731, which, via the reversing wheel 162, pulls the support rod 173 to the connector 174 until the support rod 173 and the connector 174 are connected. During this process, the shading cloth 172 is released from the winding roller 171, and the first spring 175 is twisted.

[0030] In one implementation, a groove 164 is provided on the upper end of the hydrogen discharge pipe 16 near the column 17. The connector 174 includes a sliding sleeve 1741 slidably connected inside the hydrogen discharge pipe 16. The sliding sleeve 1741 and the hydrogen discharge pipe 16 are connected by a second spring 1742. A pull rod 1743 is fixedly connected to one side of the sliding sleeve 1741. The pull rod 1743 passes through the groove 164 and abuts against the lower end of the groove 164. A downward hook 1744 is provided at the end of the pull rod 1743 away from the sliding sleeve 1741. The support rod 173 is provided with a slot 1732 with its opening facing the hook 1744. A mating groove 1733 with its opening facing upward is provided on the lower side of the slot 1732. The end of the pull rod 1743 away from the sliding sleeve 1741 is located in the slot 1732, and the hook 1744 is located in the mating groove 1733.

[0031] With the above setup, when hydrogen discharge begins, connector 174 automatically disconnects from support rod 173, allowing shade cloth 172 to wrap around winding roller 171. When hydrogen discharge pipe 16 discharges hydrogen upwards, hydrogen gas passes upwards through sliding sleeve 1741. Under the action of airflow, sliding sleeve 1741 moves upwards, driving pull rod 1743 and hook 1744 to move upwards. Second spring 1742 extends. (See above) Figure 6When the hook 1744 and the mating groove 1733 disengage, the support rod 173 and the connector 174 disengage, and the first spring 175 begins to drive the winding roller 171 to rotate. The winding roller 171 winds up the sunshade cloth 172 and drives the support rod 173 to move towards the winding roller 171. After hydrogen venting is completed, the second spring 1742 shortens, and the pull rod 1743 returns to the lower end of the slide groove 164. If the sunshade cloth 172 is needed for shading, the winch 163 pulls the support rod 173 towards the connector 174 through the first pull line 1731, that is, the slot 1732 moves closer to the hook 1744. When the pull rod 1743 is inserted into the slot 1732, the hook 1744 and the mating groove 1733 engage. Specifically, during the process of hook 1744 entering slot 1732, a slope is provided on the side of hook 1744 away from sliding sleeve 1741. Under the action of the slope, hook 1744 moves upward first, and second spring 1742 is stretched. When hook 1744 moves to mating groove 1733, second spring 1742 is shortened, and hook 1744 enters mating groove 1733 to complete the mating with mating groove 1733.

[0032] In one implementation, a rotating sleeve 165 is rotatably connected to the upper end of the hydrogen discharge pipe 16. The axis of the rotating sleeve 165 coincides with the axis of the hydrogen discharge pipe 16. A fixing member 1651 is fixedly connected to the upper end of the rotating sleeve 165. A guide sleeve 1652 is fixedly connected to one side of the fixing member 1651. The axis of the guide sleeve 1652 extends horizontally and intersects with the axis of the rotating sleeve 165. A bracket 1653 is fixedly connected inside the guide sleeve 1652. A drive shaft 1654 is rotatably connected to the bracket 1653. A blade 1655 is fixedly connected to a shaft 1654. A winding wheel 1656 is provided above the rotating sleeve 165. The drive shaft 1654 passes through the winding wheel 1656 and is rotatably connected to the winding wheel 1656. Damping oil is provided between the winding wheel 1656 and the drive shaft 1654. A first connecting rod 1745 is fixedly connected to the inner side of the sliding sleeve 1741. A second pull wire 1746 is connected to the winding wheel 1656. The second pull wire 1746 is connected to the first connecting rod 1745 and extends along the axis of the rotating sleeve 165.

[0033] With the above settings, when the natural wind force is strong, the connector 174 automatically disengages from the support rod 173, and the winding roller 171 rewinds the sunshade cloth 172, thereby preventing the sunshade cloth 172 from being broken by the wind and causing hydrogen leakage. Specifically, when the wind force is strong, the natural wind passes through the air guide sleeve 1652 and drives the air guide sleeve 1652 to rotate around the axis of the rotating sleeve 165. After the air guide sleeve 1652 rotates, its axis is basically parallel to the wind direction. See [reference needed]. Figure 7Natural wind drives the blades 1655 to rotate, which in turn drives the drive shaft 1654 to rotate. Damping oil, which can be silicone oil, is provided between the drive shaft 1654 and the winding wheel 1656, thus creating damping between them. Under this damping, the drive shaft 1654 overcomes the tension of the second spring 1742 and drives the winding wheel 1656 to rotate. The winding wheel 1656 winds the second pull wire 1746 and drives the sliding sleeve 1741 to move upward. The second spring 1742 is stretched, and the sliding sleeve 1741 drives the hook 1744 to move upward via the pull rod 1743. After the hook 1744 leaves the mating groove 1733, the connector 174 and the support rod 173 disengage. The first spring 175 drives the winding roller 171 to rotate and wind up the sunshade cloth 172.

[0034] In one implementation, the upper end of the rotating sleeve 165 is fixedly connected to a guide ring 1658 via a second connecting rod 1657, and a second pull wire 1746 passes through the guide ring 1658.

[0035] The above settings improve the stability of the second pull wire 1746.

[0036] As one implementation, the bracket 1653 includes a third connecting rod 16531 fixedly connected to the air guide sleeve 1652, a bushing 16532 fixedly connected to the third connecting rod 16531, a drive shaft 1654 passing through the bushing 16532 and rotatably connected to the bushing 16532, an annular protrusion 16541 fixedly connected to the drive shaft 1654, an annular groove 16533 provided in the bushing 16532, and the annular protrusion 16541 rotatably connected in the annular groove 16533.

[0037] With the above settings, the drive shaft 1654 can only rotate around the axis of the support 1653, and the drive shaft 1654 cannot move along the axis of the support 1653.

[0038] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
