Description

Technical Field

[0001] This application relates to the field of hydrogen storage technology, and more particularly to a high-pressure resistant hydrogen storage device. Background Technology

[0002] Hydrogen is a major industrial raw material and one of the most important industrial and specialty gases, with wide applications in petrochemicals, electronics, metallurgy, food processing, float glass, fine organic synthesis, and aerospace. At the same time, hydrogen is also an ideal secondary energy source (secondary energy refers to energy that must be produced from a primary energy source such as solar energy or coal).

[0003] Currently, hydrogen is typically stored in high-pressure resistant storage tanks, which are then released when needed. These tanks are placed inside storage containers. However, once the hydrogen in the high-pressure tanks is used up, the tanks need to be removed. Current storage containers can only lift the tanks using hoisting equipment, and the tanks are quite heavy, making removal sometimes inconvenient. Therefore, there is an urgent need for a high-pressure resistant hydrogen storage device that can solve these problems. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a high-pressure resistant hydrogen storage device to solve the problems existing in the prior art. The specific solution is as follows:

[0005] A high-pressure resistant hydrogen storage device includes a main body with multiple doors on the outside of the main body. Each door has a first placement slot for accommodating the main body of the gas storage tank. The first placement slot has a first placement plate for placing the main body of the gas storage tank. The lower end of the first placement plate is rotatably connected to the first placement slot.

[0006] Two second placement plates for clamping the main body of the gas storage tank are symmetrically arranged on the first placement plate, and each of the two second placement plates is provided with a clamping component;

[0007] The upper end of the first placement plate is provided with an adjustment component for adjusting its position. When the main body of the gas tank is in the storage state, the first placement plate is generally in a vertical state. When the main body of the gas tank is in the retrieval state, the first placement plate is generally in a horizontal state.

[0008] Preferably, the adjustment assembly includes an adjustment motor located on the outside of the main housing, the output end of the adjustment motor is provided with a winding drum for winding the adjustment rope, the first placement plate is provided with a connecting ring, and the outer end of the adjustment rope is fixedly connected to the connecting ring;

[0009] The main housing is also provided with multiple connecting rods, and each connecting rod is rotatably connected to a deflector wheel at its end. The adjusting rope passes through each deflector wheel and connects to the connecting ring.

[0010] Preferably, the clamping assembly includes a plurality of connecting blocks disposed on the second placement plate, each connecting block having a threaded adjusting pin passing through it, the inner end of the threaded adjusting pin being provided with a first clamping plate, and the inner side of the first clamping plate being provided with a rubber clamping pad.

[0011] Preferably, the first placement slot is further provided with a support assembly for supporting the main body of the gas storage tank. The support assembly includes a support plate, a support pad above the support plate, and an elastic support rod below the support plate.

[0012] Preferably, the elastic support rod includes an outer support rod disposed below the support plate, and an inner support rod is also sleeved inside the outer support rod. The outer end of the inner support rod is fixed in the first placement groove. The inner end of the inner support rod is provided with a snap-fit ​​plate, and a snap-fit ​​groove is provided below the outer support rod. The snap-fit ​​plate is slidably connected to the outer support rod through a compression spring disposed in the snap-fit ​​groove.

[0013] Preferably, the first placement slot is further provided with a limiting component, the limiting component including a plurality of first gas springs rotatably disposed in the first placement slot, and the outer end of each first gas spring is rotatably connected to a second clamping plate for limiting the main body of the gas storage tank, and the inner side of the second clamping plate is also provided with a sponge pad.

[0014] Preferably, the first placement slot is further provided with a booster assembly, which includes two second gas springs symmetrically fixed in the first placement slot. The ends of the second gas springs are provided with rubber heads, and when the gas storage tank body is in the storage state, the rubber heads abut against the outer side of the gas storage tank body.

[0015] Preferably, the door is rotatably connected to the main body, and a first handle is provided on the outside of the door.

[0016] Preferably, the main body is further provided with a plurality of top covers corresponding to the door, and the top covers are also provided with a second handle.

[0017] As can be seen from the above solution, this application provides a high-pressure resistant hydrogen storage device. When storing the main body of the gas storage tank, the door is opened, the first placement plate is adjusted to a horizontal state, and then the main body of the gas storage tank is placed on the first placement plate. It is then clamped by a clamping assembly on the second placement plate. The first placement plate is then adjusted to a vertical state by an adjusting assembly, thereby storing the main body of the gas storage tank in the first placement slot. When removing the main body of the gas storage tank, the door is opened, the first placement plate and the main body of the gas storage tank placed on it are adjusted to a horizontal state by an adjusting unit, and the clamping assembly is released to release the main body of the gas storage tank for easy access.

[0018] By adjusting the unit, the motor rotates, driving the winding drum to rotate, which in turn winds up and down the adjusting rope. This movement of the adjusting rope causes the first placement plate to rotate around the second axis, changing the gas tank's main body from a vertical position to a horizontal position or a position with a slight inclination, thus facilitating retrieval. Normally, the first placement plate is vertical under the pull of the adjusting rope. When the door is opened to lower the first placement plate, the second gas spring causes it to rotate around the second axis. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Please refer to Figure 1-8 , Figure 1 This is a schematic diagram of the overall structure of a high-pressure hydrogen storage device provided by the present invention; Figure 2 yes Figure 1 A side sectional view; Figure 3 yes Figure 2 Enlarged structural diagram at point A; Figure 4 yes Figure 2 Enlarged structural diagram at point B; Figure 5 yes Figure 2 A schematic diagram of the structure of the middle limit component; Figure 6 yes Figure 2 A schematic diagram of the structure of the clamping component; Figure 7 yes Figure 2 Structural diagram of the outer and inner support rods; Figure 8 yes Figure 2 A schematic diagram of the supporting components.

[0031] In one specific embodiment, a high-pressure resistant hydrogen storage device includes a main body 1, with multiple doors 2 on the outside of the main body 1. The multiple doors 2 are rotatably connected to the main body 1 via a first rotating shaft 3, and a first handle 4 is fixedly connected to each of the multiple doors 2 for easy opening.

[0032] Each door 2 is provided with a first placement slot 5 for accommodating the main body 9 of the gas storage tank. The first placement slot 5 is provided with a first placement plate 6 for placing the main body 9 of the gas storage tank. The lower end of the first placement plate 6 is rotatably connected to the first placement slot 5. Specifically, the lower end of the first placement plate 6 is rotatably connected to a second rotating shaft 7, and the second rotating shaft 7 is rotatably connected to a first connecting plate 8 fixedly connected to the first placement slot 5.

[0033] Two second placement plates 101 are symmetrically arranged on the first placement plate 6 for clamping the main body 9 of the gas storage tank, and each of the two second placement plates 101 is equipped with a clamping component.

[0034] The clamping assembly may include multiple connecting blocks 102 disposed on the second placement plate 101. Each connecting block 102 has a threaded adjusting pin 103 passing through it. The inner end of the threaded adjusting pin 103 is provided with a first clamping plate 104, and the inner side of the first clamping plate 104 is provided with a rubber clamping pad 105. In use, rotating the threaded adjusting pin 103 adjusts the distance between the two first clamping plates 104, facilitating the clamping of the gas storage tank body 9.

[0035] The upper end of the first placement plate 6 is provided with an adjustment component for adjusting its position. When the gas tank body 9 is in the storage state, the first placement plate 6 is generally in a vertical state. When the gas tank body 9 is in the retrieval state, the first placement plate 6 is generally in a horizontal state.

[0036] In use, open the door 2, and adjust the first placement plate 6 from a roughly vertical to a roughly horizontal position using the adjustment component. Place the gas tank body 9 onto the first placement plate 6, clamp it using the clamping component, and then adjust the first placement plate 6 from a roughly horizontal to a roughly vertical position using the adjustment component, thus storing the gas tank body 9 into the first placement slot 5. When it is necessary to remove the gas tank body 9, open the door 2, and release the first placement plate 6 and the gas tank body 9 placed on it using the adjustment unit for easy access.

[0037] The adjustment assembly may include an adjustment motor 111 located on the outside of the main housing 1. The output end of the adjustment motor 111 is provided with a winding drum 112 for winding the adjustment rope 113. The first placement plate 6 is provided with a connecting ring 114. The outer end of the adjustment rope 113 is fixedly connected to the connecting ring 114, thereby realizing the adjustment motor 111 adjusting the position of the first placement plate 6 through the adjustment rope 113.

[0038] In use, the rotating motor 111 drives the winding drum 112 to rotate, which in turn causes the winding drum 112 to wind up and unwind the adjusting rope 113. The winding up and unwinding of the adjusting rope 113 causes the first placement plate 6 to rotate around the second rotating shaft 7, turning the gas tank body 9 into a horizontal or slightly tilted state for easy access. When the gas tank body 9 is not in use, the first placement plate 6 is in a vertical state under the pull of the adjusting rope 113.

[0039] The main housing 1 is also equipped with multiple connecting rods 115, and each connecting rod 115 is rotatably connected to a directional pulley 116 at its end. The adjusting rope 113 passes through each directional pulley 116 and connects to the connecting ring 114. The connecting rods 115 facilitate the use of the adjusting rope 113.

[0040] In one specific embodiment, the first placement slot 5 is further provided with a support component for supporting the main body 9 of the gas storage tank. The support component includes a support plate 121, a support pad 122 which may be made of sponge material is provided above the support plate 121, and an elastic support rod is provided below the support plate 121.

[0041] The elastic support rod includes an outer support rod 123 located below the support plate 121, and an inner support rod 124 is also sleeved inside the outer support rod 123. The outer end of the inner support rod 124 is fixed in the first placement groove 5. The inner end of the inner support rod 124 is provided with a snap-fit ​​plate 125, and a snap-fit ​​groove 126 is provided below the outer support rod 123. The snap-fit ​​plate 125 is slidably connected to the outer support rod 123 through a compression spring 127 provided in the snap-fit ​​groove 126.

[0042] The support pad 122 on the first support plate 121, together with the inner support rod 124, outer support rod 123 and the first spring 127 below the first support plate 121, supports the main body 9 of the gas storage tank placed on the first placement plate 6.

[0043] The first placement slot is also equipped with a limiting component, which includes a plurality of first gas springs 131 rotatably disposed within the first placement slot 5. The outer end of each first gas spring 131 is rotatably connected to a second clamping plate 134 for limiting the position of the gas tank body 9. A sponge pad 136 is also provided on the inner side of the second clamping plate 134. Specifically, a second placement slot 135 is formed on the second clamping plate 134, and a sponge pad 136 is fixedly connected within the second placement slot 135. One end of each of the plurality of first gas springs 131 is rotatably connected to the first placement slot 5 via a third rotating shaft 132, and the other end of each of the plurality of first gas springs 131 is rotatably connected to the second clamping plate 134 via a fourth rotating shaft 133.

[0044] After the gas tank body 9 is placed into the first placement groove 5 on the first placement plate 6, the gas tank body 9 is clamped and limited by the sponge pad 136 provided in the second placement groove 135 on the second clamping plate 134 under the action of the first gas spring 131, thereby maintaining the stability of the gas tank body 9.

[0045] The first placement slot 5 is also equipped with a booster assembly, which includes two second gas springs 14 symmetrically fixed in the first placement slot 5. The ends of the second gas springs 14 are provided with rubber heads 15. When the gas tank body 9 is in the storage state, the rubber heads 15 abut against the outer side of the gas tank body 9. When the door 2 is opened to lower the first placement plate 6, the first placement plate 6 can be pushed to rotate around the second rotating shaft 7 under the elastic force of the second gas springs 14.

[0046] In addition, there are multiple covers 16 on the top of the main body 1 that correspond to the door 2. Each of the multiple covers 16 is equipped with a second handle 17, which makes it convenient to remove the main body 9 of the gas storage tank from another direction.

[0047] As can be seen from the above solution, this application provides a high-pressure resistant hydrogen storage device. When storing the main body of the gas storage tank, the door is opened, the first placement plate is adjusted to a horizontal state, and then the main body of the gas storage tank is placed on the first placement plate. It is then clamped by a clamping assembly on the second placement plate. The first placement plate is then adjusted to a vertical state by an adjusting assembly, thereby storing the main body of the gas storage tank in the first placement slot. When removing the main body of the gas storage tank, the door is opened, the first placement plate and the main body of the gas storage tank placed on it are adjusted to a horizontal state by an adjusting unit, and the clamping assembly is released to release the main body of the gas storage tank for easy access.

[0048] By adjusting the unit, the motor rotates, driving the winding drum to rotate, which in turn winds up and down the adjusting rope. This movement of the adjusting rope causes the first placement plate to rotate around the second axis, changing the gas tank's main body from a vertical position to a horizontal position or a position with a slight inclination, thus facilitating retrieval. Normally, the first placement plate is vertical under the pull of the adjusting rope. When the door is opened to lower the first placement plate, the second gas spring causes it to rotate around the second axis.
