Description

Technical Field

[0001] The invention relates to the technical field of hydrogen filling, and in particular to a leakage-proof hydrogenation device and a working method thereof. Background Art

[0002] As a clean and efficient new energy source, hydrogen is gradually being widely used in fields such as hydrogen fuel cell vehicles. In hydrogen refueling stations, hydrogen refueling devices are key equipment for hydrogen refueling. However, hydrogen refueling devices in the prior art have many deficiencies in terms of sealing and safety.

[0003] At present, most hydrogen fuel cell vehicles use high-pressure hydrogen storage tanks, such as 35MPa or 70MPa hydrogen storage tanks, which are connected to the hydrogen inlet of the fuel cell device through pipelines. Hydrogen refueling stations are usually also equipped with hydrogen refueling equipment of corresponding pressure levels. During the hydrogenation process, hydrogen leakage is often prone to occur due to the poor sealing performance of existing hydrogenation equipment. This leakage not only leads to a waste of energy, but more importantly, hydrogen is a flammable and explosive gas. Once leaked into the air, it may cause a fire or even an explosion, posing a serious threat to the safety of personnel and property.

[0004] In addition, existing hydrogenation equipment also has obvious defects in anti-static and open flame protection. Before hydrogenation, the hydrogen fuel cell vehicle itself, especially non-metallic parts such as tires, often carries a lot of static electricity. If the static electricity generated during the hydrogenation process is not removed in time, it may cause sparks, which in turn ignite the leaked hydrogen and cause an accident. At the same time, open flames are also a major safety hazard in the hydrogenation process and must be strictly prevented.

[0005] In view of the above problems, although some improved hydrogenation devices have appeared on the market, for example, CN112576930A discloses a safe hydrogenation device and a method of use based on a fully immersed mobile vehicle-mounted hydrogen storage device, in which the hydrogenation hydrogen transmission pipe is placed underwater or in water without interruption throughout the process, and safety protection devices and functions such as a hydrogenation gun locking device and a leakage collection gas storage room are provided, thereby completely isolating the air and harmful static electricity and open flames, and achieving complete water isolation protection during the hydrogenation process; the present invention adopts a single-layer threaded connection for connection and sealing. In order to avoid its poor sealing, the hydrogenation hydrogen transmission pipe is placed underwater or in water without interruption throughout the process, which is costly and inconvenient to operate.

[0006] There are also related technical ideas such as using a multi-layer sealing structure to improve the sealing performance, or adding anti-static and open flame protection devices, but these solutions are often complex in structure, high in cost, and have limited effects in practical applications.

[0007] In particular, for on-board hydrogen storage systems, the main dangerous feature is leakage causing high-pressure explosion. Existing hydrogenation devices are not well protected against such high-pressure leakage and lack effective real-time monitoring and emergency response mechanisms. Therefore, it is particularly important to develop a hydrogenation device that is safer in terms of explosion protection, leakage detection, and isolation of static electricity, and has a simple structure and reasonable cost.

[0008] In summary, the hydrogenation device in the prior art has obvious deficiencies in terms of sealing, anti-static, open flame protection and high-pressure leakage response, and a new type of hydrogenation device is urgently needed to solve these problems. Summary of the invention

[0024] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments: Example 1 like Figures 1 to 8As shown, a leakage-proof hydrogenation device includes a hydrogenation component 1 and a connection component connected to the hydrogenation component 1, wherein the connection component includes a connection sleeve 2 connected to the hydrogenation component 1, a slider 4 slidably connected to the connection sleeve 2, a bidirectional lead screw 10 threadedly connected to the slider 4, a driving component drivingly connected to the bidirectional lead screw 10, and a baffle 6 slidably connected to the slider 4. One end of the connection sleeve 2 is threadedly connected to a hydrogenation pipeline 3, the hydrogenation pipeline 3 passes through the baffle 6 and is rotatably connected to the baffle 6, the slider 4 is located on both sides of the bidirectional lead screw 10, and a sealing gasket 7 matching the baffle 6 is provided inside the connection sleeve 2.

[0025] In this embodiment, the driving assembly includes a worm wheel 8 connected to a bidirectional lead screw 10 and a worm 9 meshing with the worm wheel 8. The worm 9 passes through the connecting sleeve 2 and is rotationally connected to the connecting sleeve 2. A handwheel is provided at one end of the worm 9.

[0026] Furthermore, the hydrogenation pipeline 3 passes through the sealing gasket 7 .

[0027] Furthermore, the sealing gasket 7 is sleeved on the hydrogenation pipeline 3 and embedded in the inner hole of the connecting sleeve 2 , with one side surface being flush with the plane of one side of the baffle 6 and the other side surface being flush with the step surface on the connecting sleeve 2 .

[0028] Furthermore, one end of the connecting sleeve 2 is provided with a groove matching with the baffle 6, the inner ring of the baffle 6 is provided with an annular groove, a sealing ring is installed in the annular groove, the sealing ring is sleeved on the outer ring of the hydrogenation pipeline 3, and the baffle 6 is rotatably connected to the hydrogenation pipeline 3.

[0029] Furthermore, a slope 5 matching with the baffle 6 is provided on one side of the sliding block 4 , and the two are slidably connected via the slope 5 .

[0030] Furthermore, a hydrogen sensor 12 is provided at one end of the slider 4 , and an alarm light 11 is provided at the top of the connecting sleeve 2 .

[0031] Furthermore, a controller electrically connected to the hydrogen sensor 12 and the alarm light 11 is provided inside the hydrogenation assembly.

[0032] When in use, align the baffle 6 with the slot and insert the hydrogenation pipeline 3 into the connecting sleeve 2. Rotate the hydrogenation pipeline 3 to make it threadedly connected with the connecting sleeve 2 to perform primary sealing. Rotate the worm 9 by the hand wheel. Figure 7 As shown, the worm 9 drives the worm wheel 8 to rotate, and the worm wheel 8 drives the bidirectional lead screw 10 to rotate so that the two sliders 4 are close to each other, as shown in FIG. Figure 6As shown, the slider 4 squeezes the baffle 6 through the mutually coordinated slopes 5 to make it tightly against the sealing gasket 7. The sealing gasket 7 is deformed under pressure to seal the surrounding gaps, thereby further improving the overall sealing effect. Because the unidirectional transmission of the worm 9 and the worm wheel 8 can prevent the bidirectional screw 10 from rotating on its own, thereby preventing the baffle 6 from pushing the slider 4 to move. If hydrogen leaks from the connection between the hydrogenation pipeline 3 and the connecting sleeve 2, the hydrogen will also be intercepted by the sealing gasket 7 to prevent it from leaking to the outside of the present invention, and the sealing effect is good. When the hydrogen sensor 12 detects a hydrogen leak, it will transmit a signal to the controller, and the controller will transmit the signal to the alarm light 11, and the alarm light 11 will flash to warn.

[0033] Example 2 In another preferred embodiment, based on Example 1, a working method of a leak-proof hydrogenation device is to use the leak-proof hydrogenation device described in Example 1, and the method comprises: Step 1: Align the baffle 6 with the slot on the connecting sleeve 2; Step 2: insert the hydrogenation pipeline 3 into the connecting sleeve 2, and rotate the hydrogenation pipeline 3 to make it threadedly connected with the connecting sleeve 2; Step 3: Drive the bidirectional lead screw 10 to rotate through the driving assembly so that the sliders 4 approach each other; Step 4: The slider 4 squeezes the baffle 6 through the slope 5, so that the baffle 6 and the sealing gasket 7 are tightly pressed against each other, thereby sealing.

[0034] In this embodiment, during the sealing process of Step 4, if the hydrogen sensor 12 detects hydrogen leakage, the controller controls the alarm light 11 to flash and give an alarm.

[0035] Furthermore, the driving method of the driving component in Step 3 is to manually drive the worm 9 to rotate.

[0036] Example 3 In another preferred embodiment, based on embodiments 1 and 2, this embodiment will describe the technical solution of the present invention in detail in conjunction with the accompanying drawings.

[0037] This embodiment provides a leak-proof hydrogenation device, the structure of which is as follows: Figures 1 to 8 As shown, it mainly includes a hydrogenation assembly 1, a connecting sleeve 2, a hydrogenation pipeline 3, a slider 4, a slope 5, a baffle 6, a sealing gasket 7, an alarm light 11 and a hydrogen sensor 12.

[0038] The hydrogenation assembly 1 is the main part of the hydrogenation device, which is used to store and supply hydrogen. The connecting sleeve 2 is arranged at the outlet end of the hydrogenation assembly 1, and is used to connect with the hydrogenation pipeline 3. One end of the hydrogenation pipeline 3 is inserted into the connecting sleeve 2, and is connected with the hydrogenation assembly 1.

[0039] In order to ensure the sealing of the connection, the present embodiment provides a self-locking mechanism consisting of a slider 4 and a baffle 6 inside the connecting sleeve 2. The slider 4 is slidably arranged on the inner wall of the connecting sleeve 2, and the baffle 6 is arranged on the outer wall of the hydrogenation pipeline 3 and matches the slider 4. When the hydrogenation pipeline 3 is inserted into the connecting sleeve 2, the baffle 6 will push the slider 4 to slide along the inner wall of the connecting sleeve 2 until the slider 4 slides over the highest point of the slope 5 on the baffle 6, and then is stuck in the groove behind the baffle 6 under the action of its own gravity or the elastic force of the spring, thereby achieving the initial fixation between the hydrogenation pipeline 3 and the connecting sleeve 2.

[0040] In addition, in order to further enhance the sealing performance, the present embodiment further provides a sealing gasket 7 between the hydrogenation pipeline 3 and the connecting sleeve 2. The sealing gasket 7 can be made of elastic materials such as rubber and silicone and has good sealing performance. When the hydrogenation pipeline 3 is inserted into the connecting sleeve 2 and initially fixed, the sealing gasket 7 will be compressed and filled in the gap between the hydrogenation pipeline 3 and the connecting sleeve 2, thereby preventing hydrogen leakage.

[0041] The baffle 6 is disposed at the outlet end of the connecting sleeve 2 and can move relative to the connecting sleeve 2. The longitudinal section of the baffle 6 is rectangular, and its edge is tightly fitted with the inner wall of the connecting sleeve 2 to form a closed chamber. When the hydrogenation pipeline 3 is connected to the connecting sleeve 2, the baffle 6 will close the outlet of the chamber to prevent hydrogen from leaking therefrom.

[0042] In order to monitor whether there is hydrogen leakage, the present embodiment sets a hydrogen sensor 12 inside the connecting sleeve 2. The hydrogen sensor 12 can detect the hydrogen concentration in the chamber in real time. When it is detected that the hydrogen concentration exceeds the standard, it will send a signal to trigger the alarm light 11 to flash and alarm, thereby reminding the operator to handle it in time.

[0043] Working principle: When in use, the operator inserts the hydrogenation pipe 3 into the connecting sleeve 2 and achieves preliminary fixation through the self-locking mechanism. Then, push the baffle 6 to close the outlet of the chamber. Next, open the hydrogenation assembly 1 for hydrogenation operation. During the hydrogenation process, the hydrogen sensor 12 will monitor the hydrogen concentration in the chamber in real time. If a leak occurs, the hydrogen sensor 12 will immediately send a signal to trigger the alarm light 11 to flash an alarm, and the operator can handle it in time according to the alarm information.

[0044] Example 4 In another preferred embodiment, based on Example 3, this embodiment is substantially the same as Example 3, except for the structure of the self-locking mechanism. In this embodiment, the self-locking mechanism includes a thread provided on the inner wall of the connecting sleeve 2 and a matching external thread provided on the outer wall of the hydrogenation pipeline 3. When the hydrogenation pipeline 3 is inserted into the connecting sleeve 2, the external thread of the hydrogenation pipeline 3 is matched with the thread on the inner wall of the connecting sleeve 2 by rotating the hydrogenation pipeline 3, thereby achieving fixation and sealing between the hydrogenation pipeline 3 and the connecting sleeve 2.

[0045] This self-locking mechanism has a simple structure, is easy to operate, and has good sealing performance. At the same time, due to the use of threaded connection, the depth of the hydrogenation pipeline 3 inserted into the connecting sleeve 2 can be adjusted as needed to meet the use requirements in different scenarios.

[0046] Example 5 In another preferred embodiment, based on embodiments 3 and 4, this embodiment further adds intelligent control functions compared with embodiments 3 and 4. Specifically, a microprocessor is provided on the hydrogenation assembly 1 to receive the signal of the hydrogen sensor 12 and make judgments and processes according to a preset logic. When the hydrogen sensor 12 detects a hydrogen leak, the microprocessor will immediately issue an instruction to close the outlet valve of the hydrogenation assembly 1, cut off the supply of hydrogen, and trigger the alarm light 11 to flash an alarm.

[0047] In addition, the present embodiment can also establish a communication connection between the microprocessor and the remote monitoring center, and upload the leakage alarm information to the remote monitoring center in real time, so that the monitoring personnel can understand the situation in time and take corresponding treatment measures.

[0048] Through this intelligent control function, the safety and reliability of the hydrogenation device can be further improved and safety accidents caused by hydrogen leakage can be reduced.

[0049] In the preferred scheme, the driving assembly includes a worm wheel 8 connected to a bidirectional lead screw 10, and a worm 9 meshing with the worm wheel 8. The worm 9 passes through the connecting sleeve 2 and is rotatably connected to the connecting sleeve 2. A handwheel is provided at one end of the worm 9. With the above arrangement, the worm 9 can be driven to rotate by rotating the handwheel. When the worm 9 rotates, the worm wheel 8 is driven to rotate. The worm wheel 8 is connected to the bidirectional lead screw 10, thereby driving the bidirectional lead screw 10 to rotate synchronously, realizing the reciprocating movement of the slider on the lead screw, and achieving the adjustment effect.

[0050] In the preferred solution, a groove is provided inside the connecting sleeve 2, and a group of sliders 4 are clamped in the groove inside the connecting sleeve 2; the above arrangement enables the slider 4 to slide stably in the connecting sleeve 2. At the same time, a spring is provided on the side of the slider 4, and the other end of the spring is connected to the inner wall of the connecting sleeve 2 to provide a reset force for the slider 4, thereby ensuring that the slider 4 can quickly return to its original position after being subjected to external force.

[0051] In a preferred embodiment, the hydrogenation pipeline 3 passes through the sealing gasket 7. The above arrangement allows a close fit between the hydrogenation pipeline 3 and the sealing gasket 7, effectively preventing hydrogen leakage and improving the safety and stability of the overall system. In addition, the surface of the hydrogenation pipeline 3 can also be specially treated to further enhance the sealing effect between it and the sealing gasket 7.

[0052] In the preferred solution, the sealing gasket 7 is sleeved on the hydrogenation pipeline 3 and embedded in the inner hole of the connecting sleeve 2, with one side surface flush with the plane of one side of the baffle 6, and the other side surface flush with the step surface on the connecting sleeve 2; the above arrangement ensures that the sealing gasket 7 can fit tightly, effectively prevents hydrogen leakage, and improves the safety of the hydrogenation pipeline system; at the same time, the design simplifies the installation steps, facilitates later maintenance and replacement, and improves the operating efficiency of the overall equipment.

[0053] In a preferred solution, one end of the connecting sleeve 2 is provided with a groove matched with the baffle 6, the inner ring of the baffle 6 is provided with an annular groove, a sealing ring is installed in the annular groove, the sealing ring is sleeved on the outer ring of the hydrogenation pipeline 3, and the baffle 6 is rotatably connected to the hydrogenation pipeline 3; the above arrangement ensures a close fit between the connecting sleeve 2 and the baffle 6, and effectively prevents leakage of the medium; at the same time, the setting of the sealing ring enhances the sealing effect, so that the baffle 6 can still maintain good sealing performance during the rotation process, ensuring the stable operation of the hydrogenation system.

[0054] In the preferred solution, a slope 5 is provided on one side of the slider 4, which cooperates with the baffle 6, and the two are slidably connected through the slope 5. With the above arrangement, when the slider 4 moves, it can slide smoothly along the slope 5 to a position in contact with the baffle 6 to achieve a stable connection. At the same time, the design of the slope 5 also facilitates the relative position adjustment between the slider 4 and the baffle 6, thereby improving the flexibility and convenience of assembly.

[0055] In the preferred solution, a hydrogen sensor 12 is provided at one end of the slider 4, and an alarm light 11 is provided on the top of the connecting sleeve 2; with the above arrangement, when the hydrogen sensor 12 detects that the hydrogen concentration exceeds the standard, it will immediately trigger a signal to be transmitted to the alarm light 11, causing it to light up, thereby achieving an immediate warning of hydrogen leakage and ensuring the safety of the working environment.

[0056] In a preferred solution, a controller electrically connected to the hydrogen sensor 12 and the alarm light 11 is provided inside the hydrogenation assembly; the above arrangement can quickly transmit a signal to the controller through the hydrogen sensor 12 when the hydrogen concentration exceeds the standard, and the controller immediately activates the alarm light 11 to provide an immediate warning and ensure the safety of the operating environment.

[0057] In the preferred solution, during the sealing process of Step 4, if the hydrogen sensor 12 detects a hydrogen leak, the controller controls the alarm light 11 to flash and alarm; with the above settings, the controller immediately cuts off the hydrogen supply system and starts the emergency ventilation device to quickly dilute and discharge the leaked hydrogen, ensuring a safe operating environment and effectively preventing potential dangerous accidents.

[0058] In the preferred solution, the driving mode of the driving component in Step 3 is to manually drive the worm 9 to rotate; with the above setting, by manually rotating the worm 9, its rotation speed and angle can be accurately controlled, thereby adjusting the position or state of the components working with it to achieve fine operation. At the same time, the manual driving method is simple and reliable, reducing the system complexity and failure rate.

[0059] In summary, the present invention proposes an innovative anti-leakage hydrogenation device and a working method thereof, which successfully solves the key technical problems of poor sealing and easy leakage of hydrogenation devices in the field of hydrogenation technology; compared with the prior art where the hydrogenation device and the hydrogenation pipeline only rely on a single-layer threaded connection, resulting in poor sealing effect and significant safety hazards, the present invention has made significant improvements and innovations. By introducing a connection component including a connecting sleeve 2, a slider 4, a bidirectional screw 10, a drive component and a baffle 6, the present invention adds an additional sealing level on the basis of a single-layer threaded connection, thereby significantly enhancing the sealing effect; in particular, the ingenious cooperation of the slider 4, the baffle 6 and the sealing gasket 7 ensures that even in the event of a threaded connection seal failure, It can also effectively prevent hydrogen leakage, demonstrating its excellent dynamic adaptability and high sealing performance; in addition, the device is also integrated with a hydrogen sensor 12 and an alarm light 11, which can quickly sound an alarm when hydrogen leaks, further improving the safety of the device; this design not only improves the reliability of the seal, but also realizes dynamic adjustment and enhancement of the sealing effect through the clever coordination of the mechanical structure; through real-time monitoring and early warning of potential leakage risks, the present invention effectively avoids the occurrence of safety accidents; therefore, the present invention has demonstrated significant technical advantages in the structural design, sealing mechanism and safety monitoring of the hydrogenation device, opening up a new path for the development and application of hydrogenation technology and providing a safer and more reliable solution.
