Description

Technical Field

[0001] The invention belongs to the technical field of hydrogen storage tank detection, and in particular relates to a hydrogen storage tank performance detection device. Background Art

[0002] In the pressure detection of hydrogen storage tanks, water pressure test is a more traditional and commonly used method. Its principle is based on the incompressibility of water under pressure. By filling the hydrogen storage tank with water and gradually increasing the pressure, the strength and sealing of the tank body can be tested. The advantage of water pressure test lies in the stability of water. Once extreme situations such as tank rupture occur, the energy release of water is relatively moderate, reducing the possibility of instantaneous explosion and other dangers.

[0003] The patent application with publication number CN103308389A discloses a fully automatic gas tank compressive strength testing device. The gas tank is driven to roll by a roller, and the gas tank is automatically flushed with a high-pressure water pipe by an automatic control system to ensure that the internal water pressure meets the testing requirements. The testing equipment can test multiple gas tanks at the same time, with high testing efficiency and accuracy, reducing the workload of workers.

[0004] However, this technical solution still has at least the following defects: although this solution can detect multiple gas tanks, the transportation of each gas tank before and after the detection requires additional manual operations, especially the gas tank after the detection is filled with water, which greatly increases the weight of the gas tank, which is not conducive to the work after the detection.

[0053] Example 2

[0054] like Figure 4-Figure 6 As shown, in a specific embodiment, a through slot is opened in the middle of the rotating disk 104, and the support shaft 301 movably passes through the slot. The first control component includes a groove 105 and a stopper 106. The groove 105 is opened on the rotating disk 104, and the stopper 106 is fixedly connected to the end of the support plate 103, and the stopper 106 is movably connected in the groove 105;

In this configuration, the rotating disk 104 drives the guide plate 404 to rotate, and the guide plate 404 resists the blocking shaft 403, so that it drives the hook plate 401 to rotate, thereby unlocking the blocking rod 106.

[0059] like Figure 10-12 As shown, further, a second reset mechanism is provided at one end of the rotating disk 104, and the second reset mechanism includes a locking block 500 and an end plate 501. A fixed groove 502 and a movable groove 503 are provided on the end plate 501.

A first pull rope 603 is fixedly installed at the bottom of the locking rod 600, and one end of the first pull rope 603 movably passes through the top of the base 100 and extends from the side. In this setting, the locking rod 600 is pulled by the first pull rope 603, thereby unlocking the positioning plate 300 and the locking rod 600.

[0062] Example 3

[0063] like Fig.13 , Fig.14As shown, in a specific embodiment, the opening mechanism also includes a pushing device, fixed shafts 711 are installed at both ends of the unloading plate 710, and the ends of the fixed shafts 711 are plugged into the output ends of the pushing device, and the pushing device includes a cylinder 712, one end of the first pull rope 603 is fixedly connected to the fixed shaft 711, and a placement groove is opened on the top of the unloading plate 710, and the placement groove is used to place the hydrogen storage tank. In this setting, the cylinder 712 is started, and the cylinder 712 contracts to drive the unloading plate 710 to descend, and the unloading plate 710 drives the hydrogen storage tank in the placement groove to fall into the support plate 103.

[0064] like Fig.13 , Fig.14 As shown, further, the can placement unit also includes a support seat 700, a storage rack 713 is fixedly connected to the support seat 700, a splint 701 is rotatably connected to the support seat 700, a mounting block 705 is fixedly installed on the top of the support seat 700, a slide rod 704 is movably inserted on the mounting block 705, and connecting members 703 are fixedly installed at both ends of the slide rod 704, a pull rod 702 is movably hinged on one side of the connecting member 703, one end of the pull rod 702 is hinged to the splint 701, a sleeve 707 is fixedly installed at one end of the slide rod 704, the slide rod 704 is located between the sleeve 707 and the mounting block 705 and is sleeved with a second spring 706, one end of one of the connecting members 703 is installed with a second pull rope 708, one end of the second pull rope 708 is fixedly installed with a lever 709, and one end of the lever 709 is fixedly connected to the rotating shaft of the unloading plate 710. In this arrangement, during the contraction of the oil cylinder 712, the lever 709 is driven to rotate through the unloading plate 710, and then the connecting member 703 is driven to move through the second pull rope 708. The connecting member 703 is pressed against the splint 701 through the pull rod 702, so that the hydrogen storage tank on the rack 713 cannot move. When the oil cylinder 712 is reset, the second pull rope 708 is gradually reset, so that the second spring 706 drives the connecting member 703 to move by pressing against the sleeve 707. The connecting member 703 pulls the pull rod 702 so that the splint 701 releases the hydrogen storage tank, so that the hydrogen storage tank at the end can enter the placement groove on the unloading plate 710.

[0065] The implementation principle of the hydrogen storage tank performance testing device of this embodiment is as follows: when testing the performance of the hydrogen storage tank, the hydrogen storage tank is placed on the support plate 103 and fixed by the positioning plate 300, and water is injected into the hydrogen storage tank through the water pipe joint to test the pressure resistance of the hydrogen storage tank;

[0066] After the detection is completed, the power device 200 is controlled to work. The power device 200 drives the second gear 202 to rotate through the first gear 201, thereby rotating the rotating disk 104, and the rotating disk 104 drives the groove 105 to rotate, and the end of the groove 105 does not contact the blocking rod 106. At the same time, the rotating disk 104 drives the guide plate 404 to rotate, and the guide plate 404 abuts against the blocking shaft 403, so that it drives the hook plate 401 to rotate, and then the blocking rod 106 is unlocked. At this time, the groove 105 abuts against the blocking rod 106 and drives the blocking rod 106 to rotate, so that the support plate 103 rotates;

[0067] When the rotating disk 104 rotates, it drives the guide rod 303 to rotate. Before the groove 105 abuts against the blocking rod 106, the guide rod 303 does not contact the guide ring 302. At the same time, the rotating disk 104 rotates and drives the protruding column 505 to rotate and disengage from the guide surface 504. When the groove 105 abuts against the blocking rod 106, the protruding column 505 disengages from the guide surface 504, so that the first spring 509 drives the end plate 501 to move upward through the pad 510, and the locking block 500 moves from the fixed groove 502 to the movable groove 503. At the same time, the guide rod 303 abuts against the guide ring 302, so that the support shaft 301 moves, and then drives the positioning plate 300 to move to release the hydrogen storage tank. At the same time, the movement of the support shaft 301 will push the end plate 501 to rotate and pull the second tension spring 506. The positioning plate 300 drives the adapter 601 to move and engage the locking rod 600.

[0068] By controlling the rotation direction of the power device 200 according to the test results, any one of the support plates 103 can be controlled to open, so that the hydrogen storage tank can be transferred to different directions according to whether the test results are qualified;

[0069] When the hydrogen storage tank is inspected again, the power device 200 is driven in reverse to make the rotating disk 104 rotate in the reverse direction. When the rotating disk 104 rotates to the point where the groove 105 is ready to disengage from the blocking rod 106, it stops. At this time, the rotating disk 104 drives the protruding column 505 to rotate and contact the guide surface 504.

[0070] Start the oil cylinder 712, the oil cylinder 712 contracts to drive the unloading plate 710 to descend, and the unloading plate 710 drives the hydrogen storage tank in the placement groove to fall into the supporting plate 103. At this time, the oil cylinder 712 works in the reverse direction, and continues to move a distance after resetting, and then resets. In this process, the locking rod 600 is pulled by the first pull rope 603, so that the positioning plate 300 and the locking rod 600 are unlocked. At this time, the second tension spring 506 drives the end plate 501 to rotate, and drives the support shaft 301 to move. The support shaft 301 drives the positioning plate 300 to move and clamp the hydrogen storage tank. At the same time, the power device 200 continues to rotate to completely reset the rotating disk 104. The rotating disk 104 drives the boss 505 to rotate, and the end plate 501 is lowered by abutting against the guide surface 504. At this time, the locking block 500 is aligned with the fixing groove 502, so that the end plate 501 cannot rotate;

[0071] During the resetting process of the rotating disk 104, the guide plate 404 abuts against the blocking shaft 403 so that the blocking rod 106 can be reset. After the blocking rod 106 is reset, the guide plate 404 is separated from the blocking shaft 403, so that the hook plate 401 locks the blocking rod 106 under the action of the first torsion spring 402;

[0072] During the contraction of the cylinder 712, the lever 709 is driven to rotate through the unloading plate 710, and then the connecting member 703 is driven to move through the second pull rope 708. The connecting member 703 is pressed against the splint 701 through the pull rod 702, so that the hydrogen storage tank on the rack 713 cannot move. When the cylinder 712 is reset, the second pull rope 708 is gradually reset, so that the second spring 706 drives the connecting member 703 to move by pressing against the sleeve 707. The connecting member 703 pulls the pull rod 702 to make the splint 701 release the hydrogen storage tank, so that the hydrogen storage tank at the end can enter the placement groove on the unloading plate 710.

[0073] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
