Description

Technical Field

[0001] The invention relates to the technical field of hydrogen storage and hydrogenation equipment, in particular to an explosion-proof hydrogen storage and hydrogenation skid. Background Art

[0002] Hydrogen storage and refueling skid is an integrated device for hydrogen storage and refueling, which is widely used in the field of hydrogen energy. It usually integrates hydrogen storage, refueling and related control systems into a modular skid-mounted unit for easy installation and movement. The main function of hydrogen storage and refueling skid is to safely store hydrogen in high-pressure hydrogen storage tanks and refuel hydrogen into fuel cell vehicles or other hydrogen-using equipment through hydrogen refueling machines.

[0003] In the prior art, as disclosed in publication number CN116658800A, a housing, a partition, a hydrogen storage module, a compression assembly, a hydrogenation assembly and a detection control module are included. The detection control module is arranged in the housing, the detection control module is connected to the hydrogen storage module to detect the pressure information of the hydrogen storage module, and the detection control module is respectively connected to the compression assembly and the hydrogen production equipment to control the operation of the compression assembly and the hydrogen production equipment.

[0004] When the above scheme is in use, during the hydrogen filling process, since hydrogen is injected into the equipment in a high-pressure state, if the pressure change is too large, it may cause mechanical stress overload on the equipment, thereby causing equipment damage. This unstable pressure change will also increase the possibility of accidents during the filling process. Especially in a high-pressure environment, the fatigue stress of the equipment increases, which is prone to problems such as material failure or poor sealing. In addition, the equipment connection points during the hydrogen filling process must maintain good sealing and stability. If the seal fails, outside air may enter the filling system, causing hydrogen to mix with oxygen in the air, thereby increasing the risk of explosion. At the same time, impurities in the air may affect the purity of hydrogen, further increasing the potential danger. To ensure safety, it is necessary to monitor the pressure changes in real time, optimize the filling rate, and regularly check the sealing performance of the equipment to ensure that the equipment is in a safe state during the filling process.

[0005] Therefore, it is necessary to provide an explosion-proof hydrogen storage and hydrogenation skid to solve the above problems.

[0042] The gas storage tank 2 is supported by the support frame 1, and high-pressure hydrogen is stored in the gas storage tank 2. The hydrogen flows into the regulating box 6 from the bottom of the gas storage tank 2 through the connecting pipe 5, and then is connected to the gas outlet pipe 8 through the regulating box 6. One end of the gas outlet pipe 8 is connected to the gas filling pipe 9.

A group of support plates 24 are arranged on the top of the telescopic airbag 23, and a guide rod 25 is arranged on the top of the support plate 24. The guide rod 25 is a telescopic structure, and a lifting plate 27 is arranged on the top of the guide rod 25. A second elastic member 26 is sleeved on the guide rod 25, and the top of the second elastic member 26 is fixedly connected to the lifting plate 27, and the bottom of the second elastic member 26 is fixedly arranged on the support plate 24. A plurality of connecting arms 28 are arranged on one side of the lifting plate 27; a mounting groove 29 is provided at the bottom of the connecting arm 28, and a deflection arm 30 is rotatably connected in the mounting groove 29;

[0046] The guide arc plate 22 is an arc-shaped structure, which can guide the flow direction of hydrogen and reduce the impact of airflow, thereby protecting the stability of the system pipeline. One end of the connecting box 21 is connected to a telescopic airbag 23, and a guide rod 25 is arranged on the support plate 24 inside the telescopic airbag 23. The guide rod 25 is a telescopic structure. The coordinated use of the telescopic airbag 23, the guide rod 25 and the second elastic member 26 can automatically adjust the pressure fluctuation in the system, ensure the stability of the hydrogen flow, and reduce equipment wear and pressure shock; a second elastic member 26 is arranged on the guide rod 25, and the two ends of the second elastic member 26 are respectively fixed on the support plate 24 and the lifting plate 27. When the pressure fluctuates, the second elastic member 26 absorbs part of the energy to alleviate the influence of the airflow fluctuation on the system; the adjustment flexibility and safety of the system are enhanced, and the safety and reliability of the hydrogen storage and hydrogenation system are improved.

[0047] Reference Figure 10-12, a rotating rod 31 passes through the deflection arm 30, and both ends of the rotating rod 31 are arranged on the control valve 32. The control valve 32 passes through the telescopic airbag 23, and a rotating rod 33 passes through one end of the deflection arm 30, and a synchronous rod 34 is rotatably arranged on the rotating rod 33, and a limiting disk 35 is arranged at one end of the synchronous rod 34; a telescopic rod 36 is arranged at one end of the limiting disk 35, and the telescopic rod 36 has a telescopic structure, and a sealing disk 38 is arranged at one end of the telescopic rod 36.

[0048] The deflection arm 30 is driven to rotate around the axis of the rotating rod 31 through the connecting arm 28, that is, when the hydrogen pressure fluctuates and the deflection arm 30 is caused to rotate, the synchronous rod 34 can be driven to move in the control valve 32 through the rotating rod 33, and then the limit plate 35 can be driven to move synchronously. When the limit plate 35 moves, the sealing plate 38 can be driven to move through the third elastic member 37. When the sealing plate 38 is separated from the inner wall of the control valve 32, the hydrogen pressure is relatively stable at this time, and the passage of hydrogen can be achieved. When the sealing plate 38 is in contact with the inner wall of the control valve 32, the hydrogen pressure fluctuates at this time, and the hydrogen is isolated from the outside world, thereby realizing multi-stage regulation and precise control of the hydrogen flow. The sealing plate 38 is in contact with the inner wall of the control valve 32, ensuring the effective sealing of the airflow and reducing the risk of hydrogen leakage. The setting of the third elastic member 37 provides necessary buffering and adjustment capabilities, improves the flexibility and response speed of the control system, effectively improves the safety and reliability of the hydrogenation system, and adapts to complex working environments.

[0049] The present solution is specifically as follows: when the air outlet pipe 8 and the air filling pipe 9 are close to each other, the contact plates 12 are close to each other, and when one end of the contact plate 12 is in a triangular state, the first connecting plate 10 and the second connecting plate 11 can be accurately connected, thereby ensuring the accurate connection between the air outlet pipe 8 and the air filling pipe 9. At the same time, when the rotating plates 15 are close to each other, the rotating plates 15 rotate at the same time, thereby driving the moving arm 16 and the synchronous arm 20 to rotate synchronously, respectively, so as to achieve stability under the elastic force of the first elastic member 17. At the same time, when the air outlet pipe 8 and the air filling pipe 9 need to be separated, it is only necessary to move the moving arm 16. By changing the elastic force of the first elastic member 17, the rotating plate 15 can be reset and rotated, thereby realizing the separation between the gas outlet pipe 8 and the gas filling pipe 9; the guide arc plate 22 is an arc-shaped structure, which can guide the flow direction of hydrogen and reduce the impact of air flow, thereby protecting the stability of the system pipeline.

Reduce equipment wear and pressure shock; a second elastic member 26 is provided on the guide rod 25, and the two ends of the second elastic member 26 are respectively fixed on the support plate 24 and the lifting plate 27. When the pressure fluctuates, the second elastic member 26 absorbs part of the energy to alleviate the influence of the airflow fluctuation on the system; the deflection arm 30 is driven to rotate around the axis of the rotating rod 31 through the connecting arm 28, that is, when the hydrogen pressure fluctuates and the deflection arm 30 is rotated, the synchronous rod 34 can be driven to move in the control valve 32 through the rotating rod 33, thereby driving the limit plate 35 to move synchronously. When the limit plate 35 moves, the third elastic member 37 can be used to drive the seal The sealing disk 38 moves. When the sealing disk 38 is separated from the inner wall of the control valve 32, the hydrogen pressure is relatively stable, and the passage of hydrogen can be achieved. When the sealing disk 38 is in contact with the inner wall of the control valve 32, the hydrogen pressure fluctuates, and the hydrogen is isolated from the outside world, thereby achieving multi-stage regulation and precise control of the hydrogen flow. The sealing disk 38 is in contact with the inner wall of the control valve 32, ensuring effective sealing of the airflow and reducing the risk of hydrogen leakage.
