DETAILED DESCRIPTION

[0035] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0036] The present invention discloses a vertical material conveying device for a hydrogenation vertical hydrogen storage pressure vessel, such as Figure 1-2As shown, it includes a frame 800 and a vertical conveying mechanism 900. A bottom fixing seat 801 and a top fixing seat 803 are respectively constructed at the upper and lower ends of the frame 800, and a plurality of walking wheels 802 are respectively installed on both sides of the bottom fixing seat 801, so as to realize that the frame 800 walks on the box-type storage mechanism 100. The vertical conveying mechanism 900 of this embodiment is arranged on the frame 800, and the vertical conveying mechanism 900 is located between the bottom fixing seat 801 and the top fixing seat 803. The vertical hydrogen storage pressure vessel 600 is transported to the box-type storage mechanism 100 through the vertical conveying mechanism 900, or the vertical hydrogen storage pressure vessel 600 is taken out of the box-type storage mechanism 100 through the vertical conveying mechanism 900. The working principle and advantages of the present invention are as follows: the present invention transports the vertical hydrogen storage pressure vessel 600 through the vertical conveying mechanism 900, so that the vertical hydrogen storage pressure vessel 600 is always in a vertical state during the entire conveying process, and the conveying is extremely stable; because the present invention is provided with a plurality of walking wheels 802 on both sides of the bottom fixing seat 801, the rack can walk on the box-type storage mechanism 100; the vertical hydrogen storage pressure vessel 600 is transported to the box-type storage mechanism 100 through the vertical conveying mechanism 900, or the vertical hydrogen storage pressure vessel 600 is taken out from the box-type storage mechanism 100 through the vertical conveying mechanism 900; in summary, the present invention is aimed at the storage or transportation of the vertical hydrogen storage pressure vessel 600, reduces the space occupancy rate of the vertical hydrogen storage pressure vessel 600, and makes the taking and placing of the vertical hydrogen storage pressure vessel 600 quick, safe and stable, avoids the vertical hydrogen storage pressure vessel 600 from tilting or shaking during the transportation process, and improves the safety of the transportation of the vertical hydrogen storage pressure vessel 600.

[0037] As a preferred embodiment of the present invention, Figure 1 , 7 As shown in Figure 8, the box-type storage mechanism 100 includes a storage box, which is installed below the ground, and the upper end of the storage box is flush with the ground. A plurality of vertical storage units are evenly constructed in the storage box, and a plurality of vertical hydrogen storage pressure vessels 600 are arranged in each vertical storage unit. These vertical hydrogen storage pressure vessels 600 are arranged at intervals in the vertical direction. In this embodiment, since the vertical hydrogen storage pressure vessels 600 are arranged vertically in a row in the corresponding vertical storage units, the space of the storage box is reasonably and effectively utilized.

[0038] As a preferred embodiment of the present invention, Figure 5As shown, the vertical storage unit includes an assembly cylinder 104 and a material lining 700, wherein the lower end of the assembly cylinder 104 is in a closed form, and the upper end of the assembly cylinder 104 is in an open form, and the assembly cylinder 104 extends from the upper end surface of the storage box to the lower part of the storage box in the vertical direction. In this embodiment, a sealing cover is installed at the upper end of the storage box and located at the assembly cylinder 104, which is used to open or close the upper port of the assembly cylinder 104. The material lining 700 of this embodiment is installed in the assembly cylinder 104, and a plurality of vertical hydrogen storage pressure vessels 600 are placed in the material lining 700 in sequence in the vertical direction. The material lining 700 of this embodiment plays the role of supporting and accommodating the vertical hydrogen storage pressure vessel 600, and in the process of taking and placing the vertical hydrogen storage pressure vessel 600, it plays the role of connecting and cooperating with the vertical material conveying equipment, so that the taking and placing of the vertical hydrogen storage pressure vessel 600 is safer, more stable and more convenient. The specific structure of the material lining 700 of this embodiment is as follows: Figure 4 As shown, the material lining 700 includes a mounting ring 701 and a plurality of vertical support rails 702, wherein the mounting ring 701 is arranged at the upper end of the assembly cylinder 104, and the plurality of vertical support rails 702 described in this embodiment are evenly arranged on the mounting ring 701 along the circumference of the mounting ring 701, and each vertical support rail 702 extends downward from the lower end surface of the mounting ring 701 along the vertical direction to the lower end of the assembly cylinder 104.

[0039] As a preferred embodiment of the present invention, in order to separate a plurality of vertical hydrogen storage pressure vessels 600 located in the same material lining 700 and avoid direct contact between the vertical hydrogen storage pressure vessels 600, the measures taken are as follows: Figure 7-8As shown, the material liner 700 is movably installed in the assembly barrel 104, and the material liner 700 moves in the vertical direction under the action of external force. A plurality of partition assemblies are arranged in the material liner 700 at intervals in the vertical direction, and these partition assemblies divide the material liner 700 into a plurality of material cavities, and each vertical hydrogen storage pressure vessel 600 is located in a corresponding material cavities, that is, the lower end of the vertical hydrogen storage pressure vessel 600 is supported by the partition assembly, and the vertical hydrogen storage pressure vessel 600 located at the bottom is supported by the bottom wall of the assembly barrel 104. The specific structure of the partition assembly in this embodiment is that the partition assembly includes a plurality of partitions 705, wherein the same number of connecting rods 704 as the partitions 705 are evenly installed on the material liner 700 along its circumference, and one end of each partition 705 is rotatably connected to the corresponding connecting rod 704, and the partition 705 extends inwardly along the radial direction of the material liner 700. In this embodiment, a limited support platform 108 is constructed on the inner wall of the assembly cylinder 104 and at each connecting rod 704. When the material liner 700 is lowered until the partition 705 contacts the limited support platform 108, the partition 705 is limited by the limited support platform 108 and maintains a horizontal state, thereby lifting the vertical hydrogen storage pressure vessel 600. When the material liner 700 rises a certain distance, the partition 705 is separated from the limited support platform 108, and the distance between the limited support platform 108 and the partition 705 is not less than the length of the partition 705. In this way, in the process of lowering the vertical hydrogen storage pressure vessel 600, the lower end of the vertical hydrogen storage pressure vessel 600 pushes the partition 705 downward, that is, the partition 705 rotates downward along the connecting rod 704, thereby allowing the vertical hydrogen storage pressure vessel 600 to smoothly move downward in the material liner 700. In this embodiment, rubber layers are respectively provided on the upper and lower end surfaces of the partition 705, and the rubber layers play a role of buffering. Whether it is used to support the vertical hydrogen storage pressure vessel 600 when placing the vertical hydrogen storage pressure vessel 600, or in the process of transporting the vertical hydrogen storage pressure vessel 600, the surface of the partition 705 contacts the vertical hydrogen storage pressure vessel 600 to avoid scratching the vertical hydrogen storage pressure vessel 600. In addition, the rubber layer plays a role of friction on the surface of the vertical hydrogen storage pressure vessel 600, avoiding the vertical hydrogen storage pressure vessel 600 from rising or falling too fast.

[0040] As a preferred embodiment of the present invention, Figure 8As shown, one end of the partition 705 is constructed with a connecting sleeve, which is mounted on the connecting rod 704. A torsion spring is mounted on the connecting rod 704. The two ends of the torsion spring are respectively connected to the connecting rod 704 and the connecting sleeve. The function of the torsion spring is to return the partition 705, and in the process of the partition 705 being pushed open, the partition 705 gradually and smoothly rotates downward to avoid the partition 705 from colliding with the material lining 700 or the inner wall of the assembly cylinder 104. An arcuate surface 109 is constructed on the upper end surface of the limit support platform 108 of the present embodiment, and the arcuate surface 109 is adapted to the lower surface of the connecting sleeve, and the end of the limit support platform 108 away from the assembly tube 104 has a limit portion. When the partition 705 is lowered to the limit support platform 108 along with the material lining 700, the lower surface of the connecting sleeve contacts the arcuate surface 109, and the part of the partition 705 close to the connecting sleeve is supported by the limit portion of the limit support platform 108. In this way, the lower end of the vertical hydrogen storage pressure vessel 600 can be fully supported by the partition 705, and at this time the partition 705 will not flip downward.

[0041] As a preferred embodiment of the present invention, in order to enable the partition assembly to release the partition of the material liner 700, so that the vertical hydrogen storage pressure vessel 600 can smoothly enter the material liner 700, as shown in FIG. Figure 8 As shown, multiple guide rods 106 are detachably connected at the upper end of the assembly cylinder 104, each guide rod 106 vertically passes through the mounting ring 701, and a limit stopper 107 is constructed at the upper end of the guide rod 106, and the distance between the limit stopper 107 and the mounting ring 701 is not less than the length of the partition 705. In this embodiment, the material liner 700 can be lifted to a certain height so that the upper end of the material liner 700 contacts the limit stopper 107, and then the height of the material liner 700 is fixed, so that each partition 705 of the partition assembly is separated from its respective limit support platform 108, and then gradually opens under the downward pressure of the vertical hydrogen storage pressure vessel 600, so as to realize the passage of the vertical hydrogen storage pressure vessel 600. The material liner 700 of this embodiment can realize its upward movement and abut against the limit stopper 107 through the vertical conveying mechanism 900.

[0042] As a preferred embodiment of the present invention, the specific structure of the vertical conveying mechanism 900 is as follows: Figure 5-10As shown, the vertical conveying mechanism 900 includes a mounting seat 901 and a plurality of transmission assemblies 904. The mounting seat 901 has a material guide channel, and the material guide channel is used for the vertical hydrogen storage pressure vessel 600 to pass through. A sliding seat 902 is correspondingly constructed on the outer peripheral wall of the mounting seat 901, and a vertical guide rail 807 is arranged on the frame 800 and corresponding to the sliding seat 902. The sliding seat 902 is slidably connected to the corresponding vertical guide rail 807, thereby realizing the sliding connection of the mounting seat 901 on the frame 800. The plurality of transmission assemblies 904 described in this embodiment are arranged on the mounting seat 901, and these transmission assemblies 904 are located at the material guide channel and are evenly arranged along the circumference of the mounting seat 901. Each transmission assembly 904 extends vertically. When the box-type storage mechanism 100 is used to store and access the vertical hydrogen storage pressure vessel 600, the lower end of each transmission assembly 904 needs to be extended into the box-type storage mechanism 100. A vertical driving mechanism 1200 is provided on the frame 800 and located on one side of the vertical conveying mechanism 900. The vertical driving mechanism 1200 is connected to the mounting seat 901 in a transmission manner and is used to drive the mounting seat 901 to slide vertically, thereby enabling the lower end of the vertical conveying mechanism 900 to extend into the box-type storage mechanism 100 to different depths, thereby enabling the vertical hydrogen storage pressure vessels 600 at different depths to be taken and placed. The specific structure of the vertical driving mechanism 1200 of this embodiment is as follows: Figure 5 As shown, the vertical drive mechanism 1200 includes a first drive motor 1201 and a transmission screw 1202. The first drive motor 1201 is mounted on the bottom fixing seat 801. The transmission screw 1202 is coaxially assembled on the output shaft of the first drive motor 1201, and the transmission screw 1202 extends in the vertical direction. The transmission screw 1202 is threadedly connected with the connecting ear 903 on the mounting seat 901. The first drive motor 1201 is controlled to rotate forward or reverse, so that the transmission screw 1202 drives the mounting seat 901 to move upward or downward, thereby realizing the upward or downward movement of the vertical conveying mechanism 900.

[0043] As a preferred embodiment of the present invention, Fig. 9As shown, the transmission assembly 904 includes a strip-shaped mounting frame 9041 extending in the vertical direction, and a plurality of shafts 9042 are arranged at intervals in the vertical direction on the strip-shaped mounting frame 9041, and the shafts 9042 are all rotatably connected to the strip-shaped mounting frame 9041, and a transmission wheel 9043 is coaxially mounted on each shaft 9042, and the transmission wheel 9043 is fixedly connected to the corresponding shaft 9042, and the transmission wheels 9043 are transmission-connected through a first transmission belt 9044. In addition, in this embodiment, a second drive motor 905 is respectively installed on at least two transmission assemblies 904, and the output shaft of the second drive motor 905 is coaxially connected to a shaft 9042 on the corresponding transmission assembly 904. In this way, the second drive motor 905 drives the corresponding shaft 9042 to rotate forward or reverse, so that the transmission wheel 9043 on the shaft 9042 rotates, thereby driving the first transmission belt 9044 to move. The vertical hydrogen storage pressure vessel 600 is located in the vertical conveying mechanism 900, and the outer surface of the vertical hydrogen storage pressure vessel 600 is in close contact with the first transmission belt 9044 of each transmission assembly 904. During the movement of the first transmission belt 9044, the vertical hydrogen storage pressure vessel 600 moves upward or downward in the vertical direction, thereby realizing the transportation of the vertical hydrogen storage pressure vessel 600.

[0044] As a preferred embodiment of the present invention, Figure 7 As shown, the lower end of the transmission assembly 904 extends into the material lining 700, and one side surface of the first transmission belt 9044 contacts the outer surface of the vertical hydrogen storage pressure vessel 600, the other side of the first transmission belt 9044 is located in the guide groove of the vertical support rail 702, and the outer surface of the shaft 9042 contacts the vertical convex edge 7021 of the vertical support rail 702. When the vertical hydrogen storage pressure vessel 600 needs to be transported into the material lining 700, as shown in FIG. Fig.11As shown, the lower end of the transmission assembly 904 is extended into the material lining 700, and the second drive motor 905 is controlled to rotate in the opposite direction. At this time, since the outer surface of the shaft 9042 contacts the vertical flange 7021 of the vertical support rail 702, the vertical support rail 702 moves upward under the action of the shaft 9042. In order to increase the friction between the vertical support rail 702 and the shaft 9042, a rubber friction layer is provided on the surface of the vertical flange 7021 of the vertical support rail 702 and / or the shaft 9042. When the vertical support rail 702 rises until the mounting ring 701 abuts against the limit stopper 107 on the guide rod 106, the material lining 700 is always in a state of abutting against the limit stopper 107 during the entire process of lowering the vertical hydrogen storage pressure vessel 600, and the first transmission belt 9044 drives the vertical hydrogen storage pressure vessel 600 to gradually move downward. When encountering the partition assembly, since the partition 705 rises to a predetermined height along with the material lining 700, the limiting support platform 108 releases the restriction on the partition 705, so that the vertical hydrogen storage pressure vessel 600 moves downward and pushes the partition 705 open, and the vertical hydrogen storage pressure vessel 600 smoothly passes through the partition assembly and is lowered to a predetermined position. When the vertical hydrogen storage pressure vessel 600 is lowered, the vertical conveying mechanism 900 is disengaged from the vertical hydrogen storage pressure vessel 600, and the first drive motor 1201 is controlled to rotate forward, so that the material lining 700 returns to its original position. When the vertical hydrogen storage pressure vessel 600 needs to be taken out of the material lining 700, as shown in FIG. Fig.12 As shown, the lower end of the transmission assembly 904 is extended into the material lining 700, and the second drive motor 905 is controlled to rotate forward. At this time, since the outer surface of the shaft 9042 contacts the vertical convex edge 7021 of the vertical support rail 702, the vertical support rail 702 moves downward under the action of the shaft 9042, so that the mounting ring 701 of the material lining 700 is always in contact with the upper end surface of the assembly cylinder 104. The material lining 700 is always in a state of being in contact with the upper end surface of the assembly cylinder 104 during the above-mentioned process of the vertical hydrogen storage pressure vessel 600, and the first transmission belt 9044 drives the vertical hydrogen storage pressure vessel 600 to gradually move upward. When encountering a partition assembly, since the function of the limiting support platform 108 is only to block the downward turning of the partition 705, it will not hinder the upward turning of the partition 705. In this way, the vertical hydrogen storage pressure vessel 600 moves upward and pushes open the partition 705. The vertical hydrogen storage pressure vessel 600 smoothly passes through the partition assembly and rises until it leaves the material lining 700. After the vertical hydrogen storage pressure vessel 600 is taken out, the vertical conveying mechanism 900 is controlled by the vertical driving mechanism 1200 to leave the material lining 700 and close the sealing cover 105.

[0045] As a preferred embodiment of the present invention, in order to facilitate the vertical material conveying equipment to transport multiple vertical hydrogen storage pressure vessels 600, as shown in FIG. Figure 4 , 13-14, active material guiding and storage racks 1000 are respectively arranged on the frame 800 and on both sides of the vertical conveying mechanism 900, and the lower end of each active material guiding and storage rack 1000 is connected to the bottom fixed seat 801, and the height of the lower end of the active material guiding and storage rack 1000 from the ground is at least the height of a vertical hydrogen storage pressure vessel 600, and the height of the upper end of the active material guiding and storage rack 1000 from the top fixed seat 803 is at least the height of a vertical hydrogen storage pressure vessel 600, so that the vertical hydrogen storage pressure vessel 600 can enter the active material guiding and storage rack 1000 from the upper and lower ends of the active material guiding and storage rack 1000, or the vertical hydrogen storage pressure vessel 600 can be guided out of the active material guiding and storage rack 1000 from the upper and lower ends of the active material guiding and storage rack 1000.

In this embodiment, a first wheel body 1003 and a second wheel body 1009 are rotatably installed on each fixed frame 1002 along its circumference, and the first wheel body 1003 located at the same vertical position is connected through a second transmission belt 1004. The vertical hydrogen storage pressure vessel 600 is located in the active material guiding storage rack 1000, and the second transmission belt 1004 contacts the outer surface of the vertical hydrogen storage pressure vessel 600, the outer peripheral surface of the second wheel body 1009 contacts the outer surface of the vertical hydrogen storage pressure vessel 600, and one of the multiple first wheel bodies 1003 located below is connected to the power mechanism for transmission. The power mechanism drives one first wheel body 1003 to rotate, so that the corresponding second transmission belt 1004 moves, and under the joint action of the other second transmission belts 1004 and the second wheel body 1009, the vertical hydrogen storage pressure vessel 600 moves in the active material guiding storage rack 1000 in the vertical direction. The power mechanism of this embodiment includes a driven wheel 1005 connected to the corresponding first wheel body 1003, and a third driving motor 1006 is installed on the bottom fixed seat 801. The output shaft of the third driving motor 1006 is equipped with a driving wheel 1007. The driving wheel 1007 and the driven wheel 1005 are rotatably connected via a third transmission belt 1008. The third driving motor 1006 is controlled to rotate forward or reverse, so that the driving wheel 1007 drives the driven wheel 1005 to rotate through the third transmission belt 1008, and then the driven wheel 1005 drives the corresponding first wheel body 1003 to rotate.

[0046] As a preferred embodiment of the present invention, in order to transfer the vertical hydrogen storage pressure vessel 600 between the vertical conveying mechanism 900 and the active material guide storage rack 1000, as shown in FIG. Figure 3 , 15As shown in Figure 16, a material transfer mechanism 1100 is slidably installed on the top fixed seat 803, and the material transfer mechanism 1100 is used to transfer the vertical hydrogen storage pressure vessel 600 between the vertical conveying mechanism 900 and the active material guide storage rack 1000. Ladders 806 are respectively constructed on both sides of the rack 800, and each ladder 806 extends vertically from the bottom fixed seat 801 to the top fixed seat 803, and guardrails 805 are respectively installed on both sides of the top fixed seat 803. The operator can climb up to the top fixed seat 803 via the ladder 806, and operate the material transfer mechanism 1100 to carry the vertical hydrogen storage pressure vessel 600 and transfer it between the vertical conveying mechanism 900 and the active material guide storage rack 1000. The specific structure of the material transfer mechanism 1100 of this embodiment is that the material transfer mechanism 1100 includes a material bundle barrel 1101, which is arranged below the top fixed seat 803 and above the vertical conveying mechanism 900 and the active material guide storage rack 1000. An anti-slip layer 1102 is arranged in the material bundle barrel 1101. The vertical hydrogen storage pressure vessel 600 transported by the vertical conveying mechanism 900 or the active material guide storage rack 1000 moves upward, so that the vertical hydrogen storage pressure vessel 600 gradually extends. After entering the bundle barrel 1101, the anti-slip layer 1102 of the bundle barrel 1101 prevents the vertical hydrogen storage pressure vessel 600 from separating from the bundle barrel 1101. When the vertical hydrogen storage pressure vessel 600 is completely separated from the vertical conveying mechanism 900 or the active material guiding storage rack 1000, the bundle barrel 1101 is controlled to rise a certain distance, so that during the transfer of the bundle barrel 1101, the vertical conveying mechanism 900 or the active material guiding storage rack 1000 will not interfere with the vertical hydrogen storage pressure vessel 600 in the bundle barrel 1101. In this embodiment, an adjusting screw 1103 is rotatably connected to the upper end of the beam barrel 1101, and a slider 1104 is threadedly connected to the adjusting screw 1103. A strip slide 804 is provided on the top fixed seat 803, and the slider 1104 is slidably assembled on the strip slide 804. An operating handwheel 1105 is installed at the end of the adjusting screw 1103 away from the beam barrel 1101. The operator rotates the operating hand wheel 1105 to adjust the screw 1103 to drive the bundle barrel 1101 to rise, and then drives the slider 1104 to slide along the strip slide 804, so that the bundle barrel 1101 carries the vertical hydrogen storage pressure vessel 600 to the target position, and then rotates the operating hand wheel 1105 to lower the bundle barrel 1101, so that the vertical hydrogen storage pressure vessel 600 in the bundle barrel 1101 is connected to the vertical conveying mechanism 900 or the active material guiding storage rack 1000, and finally controls the vertical conveying mechanism 900 or the active material guiding storage rack 1000 to move, so that the vertical hydrogen storage pressure vessel 600 is separated from the bundle barrel 1101 and enters the vertical conveying mechanism 900 or the active material guiding storage rack 1000.
