Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen production equipment testing, and specifically to a portable hydrogen generator and its testing equipment. Background Art

[0002] Hydrogen, as a renewable, environmentally friendly and high calorific value energy, has attracted much attention. For the global energy demand in the hydrogen energy economy, hydrogen fuel will also replace fossil fuels. The hydrolysis of aluminum-alkali solution to produce hydrogen has attracted much attention in the past ten years. However, the existing hydrogen generators cannot obtain hydrogen that is convenient to carry, efficient, safe and precisely controlled, and there has been no effective breakthrough in technology.

[0003] The prior art discloses a Chinese patent with the publication number CN 210366975 U (IPC classification number: C01B3 / 06): A hydrogen generator using sodium borohydride catalysis for hydrogen production, and discloses a peristaltic pump and a catalyst bed. The peristaltic pump is controlled by a circuit control board to feed liquid into the catalyst bed, thereby controlling the hydrogen production reaction.

[0004] The prior art discloses a Chinese patent with the publication number CN 218726251 U (IPC classification number: G01N3 / 307): A device for detecting the strength of a chemical mechanical container, and discloses an impact device. The rotation of a rotating wheel drives the rotation of a rotating rod connected thereto. The rotation of the rotating rod drives the upward displacement of a transmission plate. While the transmission plate moves upward, it pulls a pull rod upward, causing the pull rod to move upward with the transmission plate. The pull rod then pulls a collision shaft upward. While the collision shaft moves, a spring is compressed by a base, and then the spring ejects to increase the speed of the collision shaft and drive a hammer to increase the impact force.

[0005] However, the above prior art still has certain defects. That is, during the use of the hydrogen generator, the peristaltic pump is controlled by a circuit control board to feed liquid to control the hydrogen production reaction, which is not convenient for later maintenance and the control method is complex; during the use of the container strength detection device, only single-point testing of the container surface can be carried out, the test results are relatively one-sided, and it is not convenient for continuous detection.

Detailed implementation manners

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0045] The hydrogen generator of the present invention is one of the devices used in the hydrogen energy industry for preparing hydrogen and belongs to a part of hydrogen production technology.

[0046] The test equipment of the present invention is one of the equipment for testing the performance of materials in the new material industry. Among them, the test equipment of the hydrogen generator is a part of the equipment for testing the performance of materials and is used for performing impact loading tests on the housing of the hydrogen generator.

[0047] Refer to the attached drawings of the specification Figures 1-2A portable hydrogen generator according to an embodiment of the present invention comprises a main body and a supporting part, wherein the main body comprises a docking ring 1 and a barrel 2 and a water barrel 3 respectively mounted at both ends of the docking ring 1, a concave hole 12 is provided at the outer axial position of the opposite ends of the barrel 2 and the water barrel 3, an air outlet pipe 16 is provided on the outer side of the barrel 2, a water replenishment pipe 17 and an air supply pipe 18 are provided on the outer side of the water barrel 3, an air bag 19 is fixedly provided on the outer side of the end of the air supply pipe 18 extending to the inside of the docking ring 1, wherein the inner circumferential surface of the docking ring 1 is set as an inner concave arc surface, which can improve the stability when the air bag 19 is used for blocking, and at the same time, control valves are installed on the air outlet pipe 16, the water replenishment pipe 17 and the air supply pipe 18, and an air outlet 20 is provided on the outer side of the air supply pipe 18 at a position corresponding to the inside of the air bag 19;

[0048] Furthermore, an inner cylinder 21 with an opening end surface that is a concave expansion setting is fixedly installed inside the barrel 2, a material-carrying mesh cylinder 22 is fixedly installed inside the inner cylinder 21, and a plug 23 is threadedly connected to the opening end of the material-carrying mesh cylinder 22, a ring plate 24 is fixedly provided at the inner edge position of the side of the docking ring 1 facing the barrel 2, a water guide ring 25 with a flat V-shaped axial cross section is fixedly provided on the inner side of the ring plate 24, and one end of the ring plate 24 extends to the concave area of ​​the opening end of the inner cylinder 21, and a gap is formed between the two for hydrogen to escape from the inner cylinder 21;

[0049] The supporting part includes a bearing seat 4, two U-shaped rods 11 are fixedly provided on the outer side of the bearing seat 4, and the two U-shaped rods 11 are rotatably installed between the ends away from the bearing seat 4 and the docking ring 1, a sinking groove 13 is opened on the top of the bearing seat 4, and a cam 14 is movably sleeved inside the sinking groove 13, and a spring 5 15 is fixedly connected between the cam 14 and the inner bottom end surface of the sinking groove 13, wherein, during the process of the spring 5 15 being compressed and restored, the bottom end of the cam 14 always remains inserted into the sinking groove 13.

[0050] It should be noted that the initial state can be set as the airbag 19 is sufficiently filled with air to seal the inner ring area of ​​the docking ring 1. At the same time, sodium borohydride is added to the inside of the material-carrying mesh tube 22, and water is injected into the water cylinder 3. In the process of using the hydrogen generator to produce hydrogen, the main body in the initial state is first flipped to allow the material barrel 2 to flip to the lower end, and in the process of flipping, the material barrel 2 is used to directly squeeze the protrusion 14, so that the protrusion 14 shrinks into the sink 13, and the spring 5 15 is compressed. After the protrusion 14 is aligned with the concave hole 12 on the outside of the material barrel 2, the protrusion 14 is inserted into the concave hole 12 under the restoring force of the spring 5 15, and the state of the main body in the current state is limited. Then, the control valve on the air supply pipe 18 is opened to release air, and the airbag 19 is released to release the blockage of the inner ring area of ​​the docking ring 1. At this time, the water in the water cylinder 3 will naturally flow into the inner cylinder 21 to immerse the sodium borohydride inside the material-carrying mesh tube 22, and hydrogen can be produced.

[0051] And during the process of hydrogen production, after a certain amount of water is put in, it is necessary to use an external inflation device to inflate the airbag 19 so that the hydrogen production process takes place inside the cartridge 2. The generated hydrogen is discharged through the outlet pipe 16 for use. If it is necessary to stop the hydrogen production process, it is necessary to release the blockage of the inner ring area of the docking ring 1 and quickly turn the main body over, so that the water cylinder 3 turns to the lower end, and the water in the inner cylinder 21 flows back into the water cylinder 3 completely under the guidance of the water diversion ring 25. After the water is separated from the sodium borohydride, the hydrogen production process can be stopped. It is flexible and convenient to use, and the hydrogen generator is small in size and easy to carry.

[0052] Specifically, as Figure 3 shown, a plurality of foot pad assemblies 5 are evenly distributed in a ring shape on the outer side of the bearing seat 4. The foot pad assembly 5 includes a U-shaped frame 51 fixed on the outer side of the bearing seat 4. A swing seat 52 is arranged inside the U-shaped frame 51. Square grooves 53 and 54 are respectively opened on both sides of the U-shaped frame 51 and the swing seat 52. The square groove 53 and the square groove 54 on the same side are communicated. Column grooves 55 are opened on the inner sides of the two square grooves 54. A cylinder 57 is movably inserted inside the column groove 55. Square columns 56 sleeved inside the communicated square groove 53 and square groove 54 are fixedly connected to the opposite ends of the two cylinders 57. Blocks are fixedly arranged on both sides of the opposite ends of the two square columns 56. A strip groove adapted to the block is opened at the position corresponding to the block on the inner side of the square groove 54. A card slot adapted to the block is opened at the position corresponding to the block on the inner side of the square groove 53. Pulling seats 58 are fixedly arranged on the opposite ends of the two square columns 56. A first spring 59 is fixedly connected between the pulling seat 58 and the outer side of the U-shaped frame 51;

[0053] A negative pressure suction attachment is fixedly embedded at one end of the swing seat 52. A column groove 510 is opened at the other end of the swing seat 52. Two Z-shaped through grooves 511 communicated with the column groove 510 are opened on the outer side of the swing seat 52. The two Z-shaped through grooves 511 are symmetrically arranged about the axis of the column groove 510. A round block 512 is movably inserted inside the column groove 510. An annular groove is opened on the outer side of the round block 512. A snap ring 513 is rotatably sleeved inside the annular groove. A lever passing through the corresponding Z-shaped through groove 511 is fixedly arranged on the outer side of the snap ring 513 at the position corresponding to the Z-shaped through groove 511. A plurality of column feet are fixedly arranged at one end of the round block 512. Among them, the column feet can be designed as columnar structures or conical structures according to actual use requirements, mainly used to make the hydrogen generator more stable when placed in outdoor use occasions, while the negative pressure suction attachment is mainly used to make the hydrogen generator more stable when placed on an indoor workbench.

[0054] It should be noted that when the first spring 59 is in the natural state, the cylinder 57 is exactly and completely inserted into the corresponding first column groove 55, and one end of the square column 56 is also inserted into the corresponding second square groove 54 on one side. Moreover, when the square column 56 is pulled outwards, when the clamping block on the outer side of the square column 56 completely slides into the corresponding clamping groove along the strip groove, the square column 56 is exactly and completely separated from the corresponding second square groove 54, while the cylinder 57 still remains in the state of being inserted into the first column groove 55. At this time, the yaw seat 52 can be toggled, and the auxiliary stabilizing part supporting the use of the hydrogen generator faces downwards, with strong applicability.

[0055] Refer to the attached drawings of the specification Figure 4 and Figures 7-8 A testing device for a portable hydrogen generator according to an embodiment of the present invention is used to perform a pressure resistance test on the main body of the above-mentioned hydrogen generator, and includes a substrate 10. A rotary detection mechanism 8 for continuously testing the main body of the hydrogen generator to be detected is provided on the top of the substrate 10. Feeding mechanisms 7 for continuous feeding are respectively provided at both ends of the rotary detection mechanism 8 and are installed on the top of the substrate 10, and a sorting mechanism 9 for sorting the main bodies of the hydrogen generators that have completed the test is provided.

[0056] The rotary detection mechanism 8 includes two bases 81 fixed on the top of the substrate 10. Feeding parts for stepwise conveying the main body of the hydrogen generator are installed on the outer sides of the two bases 81, and power parts for simulating impacts on the main body of the hydrogen generator are installed on both bases 81.

[0057] It should be noted that in the present invention, the feeding part on the rotary detection mechanism 8 is used to intermittently convey the main body of the hydrogen generator to be detected on the feeding mechanism 7 to the detection station, and the power part for simulating impacts is used to perform synchronous pressure resistance tests on the cartridge 2 and the water cylinder 3 of the main body. Then, the sorting mechanism 9 is used to classify and convey the main bodies of the hydrogen generators in which only the cartridge 2 is qualified, only the water cylinder 3 is qualified, and both are qualified.

[0058] Specifically, as Figures 4-5As shown in the figure, a feeding mechanism 6 is further provided at the position corresponding to the loading mechanism 7 on the top of the substrate 10. The feeding mechanism 6 includes a material frame 61 fixedly installed on the top of the substrate 10. Among them, the inner side of the material frame 61 can be set to an inclined structure so that the stacked main body of the hydrogen generator to be detected can be automatically replenished to the feeding site. Two limiting strips 62 are fixedly provided on both sides inside the material frame 61 to prevent the main body of the hydrogen generator to be detected from tipping over during the automatic feeding process. T-shaped chucks 63 are movably inserted through the positions between the two limiting strips 62 corresponding to the positions on both sides of the material frame 61. Among them, the end of the T-shaped chuck 63 inserted into the interior of the material frame 61 can be set to a V-shaped structure, which is convenient for pulling out the main body of the hydrogen generator to be detected at the feeding site through the material taking part on the loading mechanism 7 and blocking the subsequent replenished main body of the hydrogen generator to be detected. A second spring 64 is fixedly connected between the outer side of the T-shaped chuck 63 and the surface of the material frame 61.

[0059] Specifically, as Figure 4 and Figure 6 shown in the figure, the loading mechanism 7 includes a bracket 71 fixed on the top of the substrate 10. A cylinder 72 driven by a motor to rotate is rotatably installed inside the bracket 71. A plurality of groups of fixed blocks 73 evenly distributed in a ring are fixedly provided on the outer side of the cylinder 72, with two in each group. An adsorption platform 74 is provided at one end of each fixed block 73. A spring telescopic rod is fixedly connected between the fixed block 73 and the corresponding adsorption platform 74. Among them, the spring telescopic rod includes a sleeve rod fixedly connected to the fixed block 73 and a sleeve fixedly connected to the adsorption platform 74, and further includes a connecting spring fixedly connected between the fixed block 73 and the adsorption platform 74. One end of the sleeve rod is movably inserted into the interior of the sleeve, and the connecting spring is sleeved outside the sleeve;

[0060] A vertical rod 75 is fixedly penetrated between the two adsorption platforms 74 in each group. Guide grooves 76 are opened at the top and bottom inside the bracket 71. Among them, the guide groove 76 is composed of a connected arc groove and a V-shaped groove, and the V-shaped groove faces the feeding mechanism. Both ends of the vertical rod 75 are slidably connected to the interior of the corresponding guide groove 76.

[0061] It should be noted that during the process of the vertical rod 75 sliding within the region where the V-shaped groove is located, the sleeve rod always remains inserted inside the sleeve. Among them, when continuously feeding the main body of the hydrogen generator to be detected, the cylindrical barrel 72 is rotated by the motor. When the adsorption platform one 74 moves towards the feeding position point along with the corresponding fixed block 73, the vertical rod 75 disengages from the arc-shaped groove and moves along the inclined surface of the V-shaped groove towards the end far from the cylindrical barrel 72, bringing the adsorption platform one 74 closer to the main body of the hydrogen generator to be detected at the feeding position point. When the vertical rod 75 moves to the farthest point of the V-shaped groove, the adsorption platform one 74 comes into contact with the surface of the main body of the hydrogen generator to be detected at the feeding position point and is tightly adsorbed by the negative pressure effect. Then, as the cylindrical barrel 72 continues to rotate, the vertical rod 75 instantaneously retracts into the arc-shaped groove under the action of the spring telescopic rod, so that the adsorption platform one 74 drives the adsorbed main body of the hydrogen generator to be detected away from the feeding position point and is conveyed to the feeding position point (i.e., the position where the adsorption platform one 74 faces the rotary detection mechanism 2) along with the rotating cylindrical barrel 72.

[0062] Specifically, as Figure 7 and Figure 9 shown, both of the two feeding parts include a feeding belt 82 installed outside the corresponding base 81. The feeding belt 82 is composed of belt one, belt two, belt three, and belt four that are sequentially arranged from top to bottom and driven coaxially by a step-by-step transmission. A plurality of equally spaced strip blocks 83 are fixedly provided on the outer sides of belt one, belt two, belt three, and belt four, and limiting discs are installed on both sides of each of belt one, belt two, belt three, and belt four;

[0063] Arc strips 85 are installed at the opposite ends of the strip blocks 83 on belt two and belt three. One end of each of the arc strips 85 on one of belt two and belt three is installed with a pressure sensor 86 for controlling the operation of the power part, and positioning members 84 are installed at the opposite ends of the strip blocks 83 on one of the diagonally arranged belt one and belt four;

[0064] The positioning member 84 includes a cylinder 841 fixed on the corresponding strip block 83. The end of the telescopic end of the cylinder 841 is fixedly connected with an L-shaped rod one 842. One end of the L-shaped rod one 842 is movably inserted with a plug post 845. One end of the plug post is fixedly connected with an L-shaped rod two 843. An adsorption platform two 844 is fixedly installed at one end of the L-shaped rod two 843. Among them, a chute is opened on the outer side of the plug post 845, and a slider adapted to the chute is fixedly provided inside the slot at the end of the L-shaped rod one 842, ensuring that the adsorption platform two 844 can only move in the vertical or horizontal direction, and a spring three 846 fixedly connecting the L-shaped rod one 842 and the L-shaped rod two 843 is movably sleeved on the outer side of the plug post 845;

[0065] One end of Belt One and Belt Four of the installation positioning member 84 close to the feeding mechanism 7 is also provided with a guiding member, which is composed of a telescopic seat 87 installed outside the corresponding limiting disc and a guiding template fixed at the top of the telescopic seat 87. Among them, the structure of the telescopic seat 87 is similar to the aforementioned spring telescopic rod, so that the positioning member 84 will not be blocked during the process of moving towards each other and clamping the target object after being aligned with the main body of the hydrogen generator to be detected at the feeding position under the guidance of the guiding template, and the guiding template faces the feeding mechanism 7.

[0066] It should be noted that during the process of conveying the main body of the hydrogen generator to be detected at the feeding position to the testing station, with the transmission of the conveyor belt 82, the positioning member 84 and the arc strip 85 will synchronously perform a step-by-step transmission. When the positioning member 84 passes through the area where the guiding member is located during the transmission process, the L-shaped rod two 843 on the guiding member will move away from the L-shaped rod one 842 under the guidance of the guiding template, and stretch the spring three 846. At the same time, it drives the adsorption platform two 844 to approach the feeding position. When the two adsorption platforms two 844 move to be aligned with the axis of the main body of the hydrogen generator to be detected under the guidance of the corresponding guiding template, the cylinder 841 will drive the corresponding adsorption platform two 844 to approach the main body of the hydrogen generator to be detected, and compress the telescopic seat 87 at the corresponding position. Thus, the two adsorption platforms two 844 moving towards each other clamp the main body of the hydrogen generator to be detected, and under the guidance of the guiding template, drive the main body of the hydrogen generator to be detected to move towards the inner sides of the two sets of arc strips 85 that are opened at the corresponding positions, and the corresponding spring three 846 also gradually returns;

[0067] When the spring three 846 returns to its initial state, the L-shaped rod two 843 just completely exits the area of the guiding template, and the guiding member returns to its initial state. In this state, the main body of the hydrogen generator to be detected is just completely clamped by the two sets of arc strips 85 arranged oppositely, and the two adsorption platforms two 844 clamping the main body of the hydrogen generator at the current position remain clamped, but do not start the state of negative pressure suction of the adsorption platform two 844, and approach the testing station in this state.

[0068] Specifically, as Figure 7 and Figure 8 shown, both power units include an L-shaped frame 88 fixed outside the corresponding base 81, a through slot one and two through slots two formed through the corresponding base 81. At one end of the relatively close sides of the two bases 81 near the sorting mechanism 9, image sensors 89 for detecting the surface of the impact area of the main body of the hydrogen generator to be detected are installed;

[0069] The power unit further includes a U-shaped seat 811 fixed to the top of the base 81, a driving shaft rotatably mounted on the base 81, and two driven shafts. A driving wheel and a driven wheel are respectively fixedly sleeved on the top ends of the driving shaft and the driven shafts, and the driving wheel and the driven wheel are driven by a belt. A driving motor for driving the driving shaft to rotate is fixedly installed on the top of the U-shaped seat 811;

[0070] A turntable 810 fixedly sleeved on the outside of the two driven shafts is arranged inside each first through slot. A plurality of toothed discs 814 fixedly sleeved on the outside of the driving shaft are arranged inside each second through slot. A toothless area is arranged on the outside of each toothed disc 814, and a rack 812 meshing with the corresponding toothed disc 814 is movably inserted into each second through slot. Impact heads 813 are fixedly arranged at the opposite ends of the racks 812 on the two bases 81. Among them, the toothless areas on the plurality of toothed discs 814 are arranged in a staggered manner, so as to drive the plurality of impact heads 813 to alternately impact the surface detection area of the hydrogen generator main body to be detected. Jacks are formed at the opposite ends of the racks 812 on the two bases 81;

[0071] Guide rods 816 are fixedly arranged at the positions corresponding to each rack 812 on the inner side of the L-shaped frame 88. One end of each guide rod 816 is movably inserted into the corresponding jack, and a fourth spring 817 fixedly connecting the L-shaped frame 88 and the corresponding rack 812 is movably sleeved on the outside of each guide rod 816. A through slot 815 is formed at the top of each rack 812. One of the driven shafts movably penetrates through the through slot 815.

[0072] It should be noted that during the pressure resistance test of the hydrogen generator main body to be detected, when the hydrogen generator main body to be detected at the loading position completely disengages from the loading mechanism 7 and is completely clamped by the corresponding two arc strips 85, the corresponding pressure sensor 86 is started. After the control end receives the pressure signal, it controls the driving motor to drive the driving shaft to rotate, drives the toothed disc 814 thereon to rotate, and thus drives the corresponding rack 812 to move towards the L-shaped frame 88 on its side along the guide rod 816 and compress the fourth spring 817. When the toothless area on the toothed disc 814 is aligned with the corresponding rack 812, the rack 812 will reset under the restoring force of the corresponding fourth spring 817 and drive the impact head 813 at the end of the rack 812 to perform an impact test on the surface of the hydrogen generator main body to be detected. In addition, during the rotation of the driving shaft, the driven shaft will be driven to rotate by the transmission of the belt, so as to drive the turntable 810 to rotate, and the rotating turntable is used to drive the hydrogen generator main body to be detected to rotate, so as to realize the all-round multi-point detection of the detection area on the circumferential side of the hydrogen generator main body to be detected;

[0073] After the main body of the hydrogen generator to be detected completes the impact test, it will enter the impact area surface detection station along with the conveyor belt 82. The image sensor 89 is used to collect the impact area information on the surfaces of the cartridge 2 and the water cylinder 3 to detect whether there is surface depression. During the process of image acquisition, the turntable 810 at the corresponding position will still drive the main body of the hydrogen generator to be detected to rotate, so as to realize the acquisition of comprehensive image information;

[0074] Among them, during the process of transporting the main body of the hydrogen generator to be detected that is completely clamped by the corresponding two sets of arc-shaped strips 85 to the detection station, the rack 812 will have a blank period in which multiple racks 812 move towards the L-shaped frame 88 on their respective sides under the drive of the corresponding gear disk 814, and the main body of the hydrogen generator to be detected uses this blank period to enter the impact test site, so as to ensure the smooth progress of the conveying action.

[0075] Specifically, as Figure 4 and Figures 10-12 shown, the sorting mechanism includes a U-shaped seat II 91 and an L-shaped seat 94 on the top of the substrate 10. A rotating cylinder 92 driven by a motor is rotatably installed on the top of the U-shaped seat II 91. A clamping and opening assembly 93 is provided at the top of the rotating cylinder 92. The top of the L-shaped seat 94 is fixedly connected with a channel 95, and a notch 96 is opened at the bottom of one end of the channel 95;

[0076] The clamping and opening assembly 93 includes a groove 931 opened on the top of the rotating cylinder 92. A cross bar 932 is fixedly provided on the inner top of the groove 931. Two deflection grooves 938 communicating with the groove 931 are opened on the outer side of the rotating cylinder 92. Two rotating rods 933 are fixedly installed between the cross bar 932 and the inner bottom end surface of the groove 931;

[0077] Two gears I 934 are rotatably sleeved on the outer sides of the two rotating rods 933. One of the rotating rods 933 is movably sleeved with a clamping frame 937 that is movably inserted into the corresponding deflection groove 938 at the positions corresponding to the two deflection grooves 938, and the end of the clamping frame 937 extending into the groove 931 is fixedly connected with the gear I 934 at the corresponding position. Tooth rings 936 are fixedly provided on the opposite sides of the two gears I 934 on the outer side of the other rotating rod 933. A gear II 935 driven by a motor is rotatably installed on the inner side of the groove 931, and the gear II 935 meshes with the tooth rings 936 on the two gears I 934;

[0078] It should be noted that, in the process of sorting the main body of the hydrogen generator that has completed the pressure test, the state where the barrel 2 is located at the upper end of the main body is assumed to be the initial detection state. When the detection result shows that the pressure resistance of the barrel 2 is unqualified, the main body of the hydrogen generator will control the adsorption platform 2 844 attached to the barrel 2 to absorb the barrel 2 after leaving the surface detection station, and at the same time, control the adsorption platform 2 844 attached to the water barrel 3 to be completely separated from the water barrel 3, and then enter the left side with the transmission of the conveyor belt 82 (refer to Figure 4 ) inside the groove 95, after the main body of the hydrogen generator enters the area inside the groove 95 on the left, the adsorption platform 2 844 that adsorbs the barrel 2 is controlled to release the adsorption state and completely separate from the barrel 2, and the docking ring 1 is supported by the groove 95 on the left, and then slides along the groove 95 on the left under the push of the arc bar 85 at the corresponding position, and in the process of the main body of the hydrogen generator sliding along the groove 95 on the left, the arc bar 85 will also gradually separate from the main body of the hydrogen generator;

[0079] Similarly, when the test result shows that the pressure resistance of the water cylinder 3 is unqualified, the main body of the hydrogen generator will control the adsorption platform 2 844 attached to the barrel 2 to completely separate from the barrel 2 after leaving the surface inspection station, and at the same time, control the adsorption platform 2 844 attached to the water cylinder 3 to absorb the water cylinder 3, and then enter the right side with the transmission of the conveyor belt 82 (refer to Figure 4 ) inside the groove 95, after the main body of the hydrogen generator enters the area corresponding to the notch 96 on the inner side of the groove 95 on the right, the adsorption platform 2 844 that adsorbs the water cylinder 3 is controlled to release the adsorption state and completely separate from the water cylinder 3, and the groove 95 on the right is used to support the docking ring 1, and then the arc bar 85 at the corresponding position is moved to slide along the groove 95 on the right, and in the process of the main body of the hydrogen generator sliding along the groove 95 on the right, the arc bar 85 will also gradually separate from the main body of the hydrogen generator;

[0080] When the test results show that the pressure resistance of the barrel 2 and the water barrel 3 are both unqualified or qualified, the main body of the hydrogen generator will control the adsorption platform 2 844 attached to the barrel 2 to be completely separated from the barrel 2 after leaving the surface inspection station. At the same time, the adsorption platform 2 844 attached to the water barrel 3 is controlled to be completely separated from the water barrel 3, and the docking ring 1 is supported by two sets of oppositely arranged arc bars 85, and is centrally conveyed forward along with the conveyor belt 82. During this process, the control end controls the motor to drive the gear 2 935 to rotate, and the rotating gear 2 935 drives the ring gear 936 on the two gears 1 934 at the corresponding positions to rotate in opposite directions, so that the gear 1 934 rotating with the ring gear 936 is used to drive the two gears 1 934 on the other rotating rod 933 to rotate toward or away from each other, thereby realizing the opening and closing of the two clamping frames 937;

[0081] Further, one end of the clamping bracket 937 connected to the corresponding first gear 934 can be set as an elastic telescopic structure similar to the aforementioned spring telescopic rod (not specifically shown in the attached drawings), so that the arc bar 85 supporting the docking ring 1 can be smoothly separated from the hydrogen generator main body that has completed the detection.
