Description

Technical Field

[0001] This invention relates to the field of high-pressure hydrogen storage tank technology, specifically a hydrogen production and energy storage system. Background Technology

[0002] High-pressure hydrogen storage technology involves compressing hydrogen under high pressure and storing it in a container with high-pressure resistance. Specifically, a compressor is used to compress hydrogen until its pressure reaches the required level for storage in a hydrogen storage container, which is then stored in a specially designed and manufactured pressure-resistant vessel. It is one of the most widely used hydrogen storage technologies today and boasts high reliability.

[0003] If a high-pressure container ruptures or leaks, a large amount of high-pressure hydrogen will be released instantly, potentially triggering a serious safety accident. During the storage of high-pressure hydrogen, the internal pressure of the container needs to be monitored and dynamically adjusted in real time to prevent explosions. Because hydrogen has a relatively low energy density, conventional compressors often require multiple units to meet the requirements, and its energy consumption is high; at higher pressures, energy consumption increases exponentially. Summary of the Invention

[0004] The purpose of this invention is to provide a hydrogen production and energy storage system to solve the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A hydrogen production and storage system includes a base frame, a tank assembly, a compression mechanism, a pressure relief mechanism, and a pressure equalization mechanism. The tank assembly includes an outer tank, an inner tank, an inlet valve pipe, and a pressure sensor. The compression mechanism includes an assembly frame and a hydrogen discharge pipe. The pressure relief mechanism includes a side frame, a main valve, and a pilot valve. The main valve includes a first valve body with a first bottom hole. The pilot valve includes a servo motor. The pressure equalization mechanism includes a ring frame and a second motor. The outer tank is fixedly connected to the inner tank, the assembly frame, and the side frame. The inlet valve pipe is connected to the inner tank and the hydrogen discharge pipe via pipes. The inner tank is connected to the first bottom hole via a pipe. The inner tank is rotatably connected to the ring frame. The pressure sensor is connected to the servo motor and the second motor via electrical signals.

[0006] This invention relates to a high-pressure storage device for hydrogen. Hydrogen is introduced into a compression mechanism, where it is compressed through multiple stages. The compressed hydrogen is then loaded into a high-pressure inner tank via a hydrogen discharge pipe. A pressure sensor continuously monitors the pressure distribution within the inner tank and sends an electrical signal to a second motor. A pressure equalization mechanism rotates under the influence of the introduced hydrogen gas, ensuring that the high-pressure hydrogen is evenly distributed within the inner tank to prevent damage caused by uneven pressure distribution. When the pressure sensor detects an abnormal increase in pressure within the inner tank, it sends an electrical signal to a servo motor. The servo motor adjusts the sensitivity of the pilot valve, causing it to open in conjunction with the main valve as the pressure rises, providing emergency pressure relief to the inner tank and ensuring that the pressure does not exceed the limit and cause an explosion.

[0007] Furthermore, the tank assembly also includes an exhaust valve pipe, a heat exchange coil, and a temperature sensor. The outer tank is provided with an air inlet, an exhaust outlet, and a heat exchange hole. The air inlet is fixedly connected to the air inlet valve pipe, the exhaust valve pipe is fixedly connected to the exhaust outlet, the heat exchange coil is fixedly connected to the heat exchange hole, and the temperature sensor and the pressure sensor are both fixedly connected to the inner tank. Several groups of pressure sensors are provided, and the groups of pressure sensors are linearly and evenly distributed along the axis of the inner tank.

[0008] Hydrogen gas compressed to a high pressure in the compression mechanism is introduced into the inner tank through the inlet valve pipe and the inlet port. The temperature is monitored in real time by a temperature sensor, and several pressure sensors linearly and evenly distributed along the axis of the inner tank monitor the pressure at various points in the inner tank in real time. When hydrogen gas needs to be extracted, the exhaust valve pipe is opened to release the hydrogen gas. The temperature control medium is circulated through the heat exchange tube to ensure that the temperature of the inner tank is constant and to avoid the explosion caused by the rise of hydrogen pressure in a high-temperature environment.

[0009] Furthermore, the compression mechanism also includes a housing, a first motor, an eccentric shaft, a hydrogen inlet pipe, and a vortex mechanism. The vortex mechanism has several groups, which are linearly and evenly distributed along the axis of the housing. The vortex mechanism includes a fixed plate, an eccentric plate, and a limiting ring. The limiting ring has sliding holes. The hydrogen inlet pipe is slidably connected to a group of sliding holes away from the hydrogen outlet pipe. The housing is fixedly connected to the assembly frame, the first motor, and the fixed plate. The eccentric shaft is fixedly connected to the output end of the first motor and a group of eccentric plates away from the hydrogen outlet pipe. The fixed plate has vent holes. The housing has a first through hole and a second through hole. The first through hole is fixedly connected to the hydrogen inlet pipe, and the hydrogen outlet pipe is fixedly connected to the second through hole and a group of vent holes away from the first motor.

[0010] The first motor outputs fixed-axis torque to the eccentric shaft. An eccentric disk is mounted on the end of the eccentric shaft away from the first motor. The end of the eccentric shaft away from the first motor performs eccentric circular motion. The eccentric shaft transmits torque to the eccentric disk to perform eccentric circular motion. Hydrogen gas enters through the hydrogen inlet pipe, the first through hole, and a set of sliding holes away from the hydrogen outlet pipe. Within the set of eccentric disks, fixed disks, and limit rings away from the hydrogen outlet pipe, the hydrogen gas is compressed as the eccentric disks perform eccentric circular motion. It then passes through the vent holes and sliding holes between two adjacent sets of vortex mechanisms into the next stage of vortex mechanism. The hydrogen gas, which has undergone multiple compressions in the multi-stage vortex mechanism, enters the inlet valve pipe through the vent holes and hydrogen outlet pipe away from the first motor.

[0011] Furthermore, the vortex mechanism also includes a first vortex rail, a second vortex rail, a first spring, a limiting ring, a second spring, and an eccentric column. The fixed plate is also provided with a limiting frame, the eccentric plate is provided with a protrusion and a through groove, and the limiting ring is also provided with a protruding column. The first vortex rail is fixedly connected to the fixed plate, the second vortex rail is fixedly connected to the eccentric plate and the eccentric column, the eccentric column is fixedly connected to the adjacent eccentric plate, and the eccentric column contacts the vent hole. The limiting ring contacts the fixed plate, the eccentric plate, and the first vortex rail. The first spring is fixedly connected to the limiting frame and the protrusion, and the limiting frame is slidably connected to the protrusion. The second spring is fixedly connected to the through groove and the protruding column, and the through groove is slidably connected to the protruding column.

[0012] External hydrogen gas enters through the hydrogen inlet pipe, the first through hole, and a set of sliding holes away from the hydrogen outlet pipe. The eccentric disk performs eccentric circular motion. The protrusion moves back to its original position within the limiting frame, compressing the first spring. The outer edge of the second vortex rail contacts the limiting ring. The protrusion moves back to its original position within the through groove, compressing the second spring. The eccentric disk is assembled with the second vortex rail, which performs eccentric circular motion. The limiting frame and the through groove work together to limit the eccentric circular motion of the eccentric disk and the limiting ring, restricting the rotation of the eccentric disk. The first vortex rail is fixedly assembled on the fixed disk. As the second vortex rail performs eccentric circular motion relative to the first vortex rail, the second vortex rail and the first vortex rail... The vortex rails mesh with each other to form several dynamically changing crescent-shaped chambers. Hydrogen gas is in a sealed space composed of an eccentric disk, a fixed disk, and a limiting ring, located away from the hydrogen exhaust pipe. The hydrogen gas located at the outer edge of the second vortex rail is compressed step by step by multiple chambers. Finally, the compressed hydrogen gas is squeezed towards the center of the vortex and passes through the vent holes and sliding holes between two adjacent sets of vortex compression mechanisms into the next stage of vortex compression mechanism. The eccentric column is assembled with the second vortex rail and the adjacent eccentric disk. The eccentric column moves eccentrically in the vent holes along with the second vortex rail. The eccentric column transmits the eccentric circular motion torque to the adjacent eccentric disk. The hydrogen gas completes multiple compressions in the multi-stage vortex compression mechanism.

[0013] Furthermore, the pressure relief mechanism also includes a throttle, the main valve also includes a first valve cover, the pilot valve also includes a second valve body, the first valve body is also provided with a first side hole, the first valve cover is provided with a second side hole, the second valve body is provided with a second bottom hole and a third side hole, the throttle is connected to the first side hole and the second bottom hole through a pipe, and the second side hole and the third side hole are connected through a pipe.

[0014] The first bottom hole on the first valve body is connected to the inner tank through a pipe. When the gas pressure in the inner tank is within the threshold range, the high-pressure hydrogen in the inner tank flows back to the main valve through the first side hole, the throttle, the second valve body, and the third side hole. At this time, the main valve is in the closed state.

[0015] Furthermore, the main valve also includes a third spring and a valve core cover. The first valve body is also provided with a first pressure relief port, which is located on the side of the first valve body away from the first side hole. The first valve cover is fixedly connected to the first valve body. The third spring is fixedly connected to both the first valve cover and the valve core cover. The valve core cover is slidably connected to both the first valve cover and the first valve body. The upper side of the first valve cover and the valve core cover forms the main air chamber, and the lower side of the first valve body and the valve core cover forms the pressure-inducing chamber.

[0016] When the gas pressure in the inner tank is within the threshold range, the pilot valve closes, and high-pressure hydrogen gas is introduced into the main valve through the first bottom hole. It then flows back into the main gas chamber through the first side hole, the throttle, the second valve body, and the third side hole. At this time, the gas pressure in the main gas chamber is equal to that in the pressure-sensing chamber. The valve core cover, under the action of the third spring, seals against the first valve body, preventing the first pressure relief port from connecting. The hydrogen gas in the pressure-sensing chamber cannot open the valve core cover, and the high-pressure hydrogen gas in the inner tank is not connected to the outside. When the gas pressure rises abnormally, the pilot valve opens, and the hydrogen gas in the main gas chamber flows through… Hydrogen gas in the pressure chamber is discharged through the pilot valve via the second side hole. Hydrogen gas in the pressure chamber is discharged through the first side hole and the throttle valve. Because the throttle valve blocks the discharge of hydrogen gas in the pressure chamber, the discharge rate of hydrogen gas in the main gas chamber is much greater than that in the pressure chamber. The gas pressure in the pressure chamber is greater than that in the main gas chamber. The valve core cover moves towards the first valve cover and squeezes the third spring. Hydrogen gas in the main gas chamber is discharged into the outside through the first pressure relief port. As the gas pressure decreases, the pilot valve closes, achieving the effect of emergency pressure relief.

[0017] Furthermore, the pilot valve also includes a second valve cover, a fourth spring, and a valve core. The second valve cover is fixedly connected to the second valve body and the servo motor. The second valve body is also provided with a second pressure relief port, which is located on the side of the second valve body away from the third side hole. The fourth spring is fixedly connected to the output end of the servo motor and the valve core. The valve core is slidably connected to the second valve cover and the second valve body.

[0018] When the gas pressure in the inner tank rises abnormally, the hydrogen pressure in the second valve body overcomes the set pressure of the fourth spring. The hydrogen pressure pushes the valve core column to move closer to the second valve cover. The valve core column squeezes the fourth spring, and the valve core column no longer blocks the second pressure relief port, allowing the pilot valve to connect with the outside. The servo motor outputs torque, causing the end of the fourth spring away from the valve core column to twist, thereby changing the set pressure of the fourth spring and adjusting the sensitivity of the pilot valve.

[0019] Furthermore, the pressure equalization mechanism also includes a first gear, a second gear, fan blades, and a crank. The second motor is fixedly connected to the ring frame. Several sets of fan blades and cranks are provided, and the several sets of fan blades and cranks are evenly distributed along the circumference of the ring frame. The output end of the second motor is fixedly connected to the first gear. The tooth surfaces of the first gear and the second gear mesh. The second gear is fixedly connected to a set of fan blades. The fan blades are rotatably connected to the ring frame, and the fan blades are hinged to the cranks.

[0020] Hydrogen gas compressed to a high pressure is introduced into the inner tank through the inlet valve pipe and inlet. The high-pressure hydrogen gas blows onto the fan blades, causing the ring frame to rotate as a whole. When the pressure sensor detects uneven pressure distribution in the inner tank, it sends an electrical signal to the second motor. The second motor outputs a fixed-axis torque to the first gear. Through the meshing of the teeth of the first and second gears, the torque is transmitted to a set of fan blades, causing the fan blades to rotate around their own axis. Several sets of fan blades evenly distributed along the circumference of the ring frame are synchronously connected by crank hinges. When the tilt angle between the fan blades and the ring frame increases, the high-pressure hydrogen gas passing through the fan blades accelerates and diffuses into the inner wall of the inner tank, making the hydrogen gas in the inner tank evenly distributed.

[0021] Compared with the prior art, the beneficial effects of this invention are as follows: This invention designs a compression mechanism. A first motor outputs a fixed-axis torque to an eccentric disk to perform eccentric circular motion. A second vortex rail meshes with the first vortex rail, forming several dynamically changing chambers. Hydrogen gas at the outer edge is compressed and squeezed towards the center of the vortex by multiple chambers, and then passes through the vent between adjacent groups to the next stage. The eccentric column transmits torque to the next stage eccentric disk, and the hydrogen gas completes multiple compressions. By designing a multi-stage interconnected vortex compression mechanism, the compression efficiency and hydrogen purity are improved, while reducing the compressor load and extending its service life. This invention also designs a pressure relief mechanism. When the gas pressure in the inner tank is within a threshold range, the pilot valve is closed, and the hydrogen gas flows back to the main gas chamber through the first side hole, the throttle, and the second valve body. The gas pressure in the main gas chamber is equal to that in the pressure-reducing chamber, the valve core cover is sealed, and the first pressure relief port is not connected. When the gas pressure rises abnormally, the hydrogen pressure overcomes the setting pressure of the fourth spring, and the valve core column... The displacement of the valve core cover removes the obstruction of the second pressure relief port, allowing the pilot valve to connect with the outside. Hydrogen in the main gas chamber is discharged through the second side hole into the pilot valve, while hydrogen in the pressure relief chamber is discharged through the first side hole and the throttle valve. The throttle valve obstructs the hydrogen in the pressure relief chamber, resulting in a much higher discharge rate of hydrogen in the main gas chamber compared to the pressure relief chamber. Consequently, the pressure in the pressure relief chamber is higher than that in the main gas chamber, causing the valve core cover to shift. Hydrogen in the main gas chamber is then discharged into the outside through the first pressure relief port. As the pressure decreases, the pilot valve closes, achieving the emergency pressure relief function and ensuring the safety of the tank. This invention also incorporates an air distribution mechanism. By increasing the tilt angle between the fan blades and the ring frame, the high-pressure hydrogen passing through the fan blades accelerates its diffusion towards the inner wall of the tank, ensuring a uniform distribution of hydrogen within the inner tank and preventing damage caused by uneven pressure distribution. This invention can compress hydrogen in multiple stages, improving compression efficiency and hydrogen purity, reducing the compressor load, detecting internal pressure, and actively relieving and equalizing pressure to ensure tank safety and prevent explosions.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 8 The present invention provides a technical solution for a hydrogen production and storage system, comprising a base frame 1, a tank assembly 2, a compression mechanism 3, a pressure relief mechanism 4, and a pressure equalization mechanism 5. The tank assembly 2 includes an outer tank 21, an inner tank 22, an inlet valve pipe 23, and a pressure sensor 27. The compression mechanism 3 includes an assembly frame 31 and a hydrogen discharge pipe 36. The pressure relief mechanism 4 includes a side frame 41, a main valve 42, and a pilot valve 43. The main valve 42 includes a first valve body 421, on which a first bottom hole 42 is provided. 11. The pilot valve 43 includes a servo motor 434, the pressure equalization mechanism 5 includes a ring frame 51 and a second motor 52, the outer tank 21 is fixedly connected to the inner tank 22, the assembly frame 31 and the side frame 41, the inlet valve pipe 23 is connected to the inner tank 22 and the hydrogen discharge pipe 36 through pipes, the inner tank 22 is connected to the first bottom hole 4211 through pipes, the inner tank 22 is rotatably connected to the ring frame 51, and the pressure sensor 27 is connected to the servo motor 434 and the second motor 52 through electrical signals.

[0033] This invention relates to a high-pressure storage device for hydrogen. Hydrogen is introduced into a compression mechanism 3, where it is compressed through multiple stages. The compressed hydrogen is then loaded into an inner tank 22 under high pressure via a hydrogen discharge pipe 36. A pressure sensor 27 monitors the pressure distribution within the inner tank 22 in real time and sends an electrical signal to a second motor 52. The pressure equalization mechanism 5 rotates under the influence of the introduced hydrogen gas, ensuring that the high-pressure hydrogen is evenly distributed within the inner tank 22, preventing damage caused by uneven pressure distribution. When the pressure sensor 27 detects an abnormal increase in pressure within the inner tank 22, it sends an electrical signal to a servo motor 434. The servo motor 434 adjusts the sensitivity of the pilot valve 43, causing it to open in conjunction with the main valve 42 as the pressure increases, thus providing emergency pressure relief to the inner tank 22 and ensuring that the pressure within the inner tank 22 does not exceed the limit and cause an explosion.

[0034] like Figure 2As shown, the tank assembly 2 also includes an exhaust valve pipe 24, a heat exchange coil 25, and a temperature sensor 26. The outer tank 21 is provided with an air inlet 211, an exhaust port 212, and a heat exchange hole 213. The air inlet 211 is fixedly connected to the air inlet valve pipe 23, the exhaust valve pipe 24 is fixedly connected to the exhaust port 212, the heat exchange coil 25 is fixedly connected to the heat exchange hole 213, and the temperature sensor 26 and the pressure sensor 27 are both fixedly connected to the inner tank 22. Several groups of pressure sensors 27 are provided, and the several groups of pressure sensors 27 are linearly and evenly distributed along the axis of the inner tank 22.

[0035] Hydrogen gas compressed to a high pressure in the compression mechanism 3 is introduced into the inner tank 22 through the inlet valve pipe 23 and the inlet port 211. The temperature is monitored in real time by the temperature sensor 26, and several pressure sensors 27 linearly and evenly distributed along the axis of the inner tank 22 monitor the pressure at various points in the inner tank 22 in real time. When hydrogen gas needs to be extracted, the exhaust valve pipe 24 is opened to discharge the hydrogen gas. The temperature control medium is circulated through the heat exchange coil 25 to ensure that the temperature of the inner tank 22 is constant and to avoid the explosion caused by the rise of hydrogen pressure under high temperature environment.

[0036] like Figure 3 , Figure 4 As shown, the compression mechanism 3 also includes a housing 32, a first motor 33, an eccentric shaft 34, a hydrogen inlet pipe 35, and a vortex compression mechanism 37. Several sets of vortex compression mechanisms 37 are provided, linearly and evenly distributed along the axis of the housing 32. Each vortex compression mechanism 37 includes a fixed disk 371, an eccentric disk 372, and a limiting ring 376. The limiting ring 376 has sliding holes 3762. The hydrogen inlet pipe 35 is slidably connected to a set of sliding holes 3762 located away from the hydrogen outlet pipe 36. The housing 32 and the mounting frame... 31. The first motor 33 and the fixed disk 371 are fixedly connected. The eccentric shaft 34 is fixedly connected to the output end of the first motor 33 and a set of eccentric disks 372 away from the hydrogen exhaust pipe 36. The fixed disk 371 is provided with a vent hole 3711. The outer shell 32 is provided with a first through hole 321 and a second through hole 322. The first through hole 321 is fixedly connected to the hydrogen inlet pipe 35. The hydrogen exhaust pipe 36 is fixedly connected to the second through hole 322 and a set of vent holes 3711 away from the first motor 33.

[0037] The first motor 33 outputs fixed-axis torque to the eccentric shaft 34. An eccentric disk 372 is mounted on the end of the eccentric shaft 34 away from the first motor 33. The end of the eccentric shaft 34 away from the first motor 33 performs eccentric circular motion. The eccentric shaft 34 transmits torque to the eccentric disk 372 to perform eccentric circular motion. Hydrogen gas is introduced through the hydrogen inlet pipe 35, the first through hole 321, and a set of sliding holes 3762 away from the hydrogen outlet pipe 36. The hydrogen gas is compressed within the set of eccentric disks 372, the fixed disk 371, and the limiting ring 376 away from the hydrogen outlet pipe 36 as the eccentric disk 372 performs eccentric circular motion. It is then introduced into the next stage of the vortex mechanism 37 through the vent hole 3711 and the sliding hole 3762 between two adjacent sets of vortex mechanisms 37. The hydrogen gas, which has been compressed multiple times in the multi-stage vortex mechanism 37, is introduced into the intake valve pipe 23 through the set of vent holes 3711 away from the first motor 33 and the hydrogen outlet pipe 36.

[0038] like Figure 4 As shown, the vortex mechanism 37 also includes a first vortex rail 373, a second vortex rail 374, a first spring 375, a limiting ring 376, a second spring 377, and an eccentric column 378. A limiting bracket 3712 is also provided on the fixed disk 371. A protrusion 3721 and a through groove 3722 are provided on the eccentric disk 372. A protrusion 3761 is also provided on the limiting ring 376. The first vortex rail 373 is fixedly connected to the fixed disk 371, and the second vortex rail 374 is fixedly connected to both the eccentric disk 372 and the eccentric column 378. Next, the eccentric column 378 is fixedly connected to the adjacent eccentric disk 372, and the eccentric column 378 contacts the vent 3711. The limiting ring 376 contacts the fixed disk 371, the eccentric disk 372, and the first vortex rail 373. The first spring 375 is fixedly connected to the limiting frame 3712 and the protrusion 3721. The limiting frame 3712 is slidably connected to the protrusion 3721. The second spring 377 is fixedly connected to the through groove 3722 and the protrusion 3761. The through groove 3722 is slidably connected to the protrusion 3761.

[0039] External hydrogen gas is introduced through the hydrogen inlet pipe 35, the first through hole 321, and a set of sliding holes 3762 away from the hydrogen outlet pipe 36. The eccentric disk 372 performs eccentric circular motion. The protrusion 3721 moves back to its original position within the limiting frame 3712, compressing the first spring 375. The outer edge of the second vortex rail 374 contacts the limiting ring 376. The protrusion 3761 moves back to its original position within the through groove 3722, compressing the second spring 377. The eccentric disk 372 is equipped with the second vortex rail 374, which performs eccentric circular motion. The limiting frame 3712 and the through groove 3722 work together to limit the eccentric circular motion of the eccentric disk 372 and the limiting ring 376, restricting the rotation of the eccentric disk 372. The first vortex rail 373 is fixedly mounted on the fixed disk 371. As the second vortex rail 374 performs eccentric circular motion relative to the first vortex rail 373... The second vortex rail 374 meshes with the first vortex rail 373 to form several dynamically changing crescent-shaped chambers. Hydrogen gas is in a sealed space composed of a set of eccentric disks 372, fixed disks 371, and limiting rings 376, away from the hydrogen exhaust pipe 36. Hydrogen gas located at the outer edge of the second vortex rail 374 is compressed step by step by multiple chambers. Finally, the compressed hydrogen gas is squeezed towards the center of the vortex and passes through the vent hole 3711 and sliding hole 3762 between two adjacent sets of vortex compression mechanisms 37 into the next stage of vortex compression mechanism 37. The eccentric column 378 is assembled with the second vortex rail 374 and the adjacent eccentric disk 372. The eccentric column 378 moves eccentrically in the vent hole 3711 along with the second vortex rail 374. The eccentric column 378 transmits the eccentric circular motion torque to the adjacent eccentric disk 372. Hydrogen gas is compressed multiple times in the multi-stage vortex compression mechanism 37.

[0040] like Figure 5 As shown, the pressure relief mechanism 4 also includes a throttle 44, the main valve 42 also includes a first valve cover 422, and the pilot valve 43 also includes a second valve body 431. The first valve body 421 is also provided with a first side hole 4212, the first valve cover 422 is provided with a second side hole 4221, and the second valve body 431 is provided with a second bottom hole 4311 and a third side hole 4312. The throttle 44 is connected to the first side hole 4212 and the second bottom hole 4311 through pipes, and the second side hole 4221 is connected to the third side hole 4312 through pipes.

[0041] The first bottom hole 4211 on the first valve body 421 is connected to the inner tank 22 through a pipe. When the gas pressure in the inner tank 22 is within the threshold range, the high-pressure hydrogen in the inner tank 22 flows back to the main valve 42 through the first side hole 4212, the throttle 44, the second valve body 431, and the third side hole 4312. At this time, the main valve 42 is in the closed state.

[0042] like Figure 6 , Figure 7As shown, the main valve 42 also includes a third spring 423 and a valve core cover 424. The first valve body 421 is also provided with a first pressure relief port 4213, which is located on the side of the first valve body 421 away from the first side hole 4212. The first valve cover 422 is fixedly connected to the first valve body 421. The third spring 423 is fixedly connected to both the first valve cover 422 and the valve core cover 424. The valve core cover 424 is slidably connected to both the first valve cover 422 and the first valve body 421. The upper side of the first valve cover 422 and the valve core cover 424 forms the main air chamber 425, and the lower side of the first valve body 421 and the valve core cover 424 forms the pressure-inducing chamber 426.

[0043] When the gas pressure in the inner tank 22 is within the threshold range, the pilot valve 43 closes, and high-pressure hydrogen gas is introduced into the main valve 42 through the first bottom hole 4211. It then flows back into the main gas chamber 425 through the first side hole 4212, the throttle 44, the second valve body 431, and the third side hole 4312. At this time, the gas pressure in the main gas chamber 425 is equal to that in the pressure-sensing chamber 426. The valve core cover 424, under the action of the third spring 423, seals against the first valve body 421, preventing the first pressure relief port 4213 from connecting. The hydrogen gas in the pressure-sensing chamber 426 cannot open the valve core cover 424, and the high-pressure hydrogen gas in the inner tank 22 is not connected to the outside. When the gas pressure rises abnormally, the pilot valve 43 opens, and the hydrogen gas in the main gas chamber 425... Hydrogen gas is discharged through the second side hole 4221 into the pilot valve 43. Hydrogen gas in the pressure chamber 426 is discharged through the first side hole 4212 and the throttle 44 into the pilot valve 43. Because the throttle 44 blocks the discharge of hydrogen gas in the pressure chamber 426, the discharge rate of hydrogen gas in the main gas chamber 425 is much greater than that in the pressure chamber 426. The gas pressure in the pressure chamber 426 is greater than that in the main gas chamber 425. The valve core cover 424 moves towards the first valve cover 422 and squeezes the third spring 423. Hydrogen gas in the main gas chamber 425 is discharged into the outside through the first pressure relief port 4213. As the gas pressure decreases, the pilot valve 43 closes, achieving the effect of emergency pressure relief.

[0044] like Figure 7 As shown, the pilot valve 43 also includes a second valve cover 432, a fourth spring 433, and a valve core 435. The second valve cover 432 is fixedly connected to the second valve body 431 and the servo motor 434. The second valve body 431 is also provided with a second pressure relief port 4313, which is located on the side of the second valve body 431 away from the third side hole 4312. The fourth spring 433 is fixedly connected to the output end of the servo motor 434 and the valve core 435. The valve core 435 is slidably connected to the second valve cover 432 and the second valve body 431.

[0045] When the gas pressure in the inner tank 22 rises abnormally, the hydrogen pressure in the second valve body 431 overcomes the set pressure of the fourth spring 433. The hydrogen pressure pushes the valve core column 435 to move closer to the second valve cover 432. The valve core column 435 squeezes the fourth spring 433, and the valve core column 435 no longer blocks the second pressure relief port 4313, allowing the pilot valve 43 to connect with the outside. The servo motor 434 outputs torque, causing the end of the fourth spring 433 away from the valve core column 435 to twist, thereby changing the set pressure of the fourth spring 433 and adjusting the sensitivity of the pilot valve 43.

[0046] like Figure 8 As shown, the pressure equalization mechanism 5 also includes a first gear 53, a second gear 54, fan blades 55 and cranks 56. The second motor 52 is fixedly connected to the ring frame 51. Several sets of fan blades 55 and cranks 56 are provided. Several sets of fan blades 55 and cranks 56 are evenly distributed along the circumference of the ring frame 51. The output end of the second motor 52 is fixedly connected to the first gear 53. The first gear 53 meshes with the tooth surfaces of the second gear 54. The second gear 54 is fixedly connected to a set of fan blades 55. The fan blades 55 are rotatably connected to the ring frame 51. The fan blades 55 are hinged to the cranks 56.

[0047] Hydrogen gas compressed to a high pressure state is introduced into the inner tank 22 through the inlet valve pipe 23 and the inlet port 211. The high-pressure hydrogen gas blows onto the fan blades 55, causing the ring frame 51 to rotate as a whole. When the pressure sensor 27 detects uneven pressure distribution in the inner tank 22, it sends an electrical signal to the second motor 52. The second motor 52 outputs a fixed-axis torque to the first gear 53. Through the meshing of the teeth of the first gear 53 and the second gear 54, the torque is transmitted to a set of fan blades 55, causing the fan blades 55 to rotate around their own axis. Several sets of fan blades 55, evenly distributed along the circumference of the ring frame 51, are hinged synchronously through the crank 56. When the tilt angle between the fan blades 55 and the ring frame 51 increases, the high-pressure hydrogen gas passing through the fan blades 55 accelerates and diffuses into the inner wall of the inner tank 22, making the hydrogen gas in the inner tank 22 evenly distributed.

[0048] The working principle of this invention: External hydrogen gas is introduced through the hydrogen inlet pipe 35. The first motor 33 outputs a fixed-axis torque to the eccentric disk 372 to perform eccentric circular motion. The outer edge of the second vortex rail 374 contacts the limiting ring 376. The second vortex rail 374 and the first vortex rail 373 mesh with each other to form several dynamically changing chambers. The hydrogen gas at the outer edge is compressed and squeezed towards the center of the vortex by multiple chambers in stages. It is introduced into the next stage through the vent hole 3711 between two adjacent groups. The eccentric column 378 transmits torque to the next stage eccentric disk 372. The hydrogen gas completes multiple compressions and is introduced. Inside the inner tank 22, several pressure sensors 2 monitor the pressure at various points within the inner tank 22. When the pressure in the inner tank 22 is within a threshold range, the pilot valve 43 closes, and the hydrogen in the pressure chamber 426 flows back to the main gas chamber 425 through the first side port 4212, the throttle 44, the second valve body 431, and the third side port 4312. At this time, the pressure in the main gas chamber 425 is equal to that in the pressure chamber 426. The valve core cover 424 seals against the first valve body 421, preventing the first pressure relief port 4213 from connecting. When the pressure rises abnormally... When the hydrogen pressure inside the second valve body 431 overcomes the set pressure of the fourth spring 433, the hydrogen valve core 435 shifts, no longer blocking the second pressure relief port 4313, allowing the pilot valve 43 to connect with the outside. The servo motor 434 outputs torque to twist the fourth spring 433, changing its set pressure and adjusting the sensitivity of the pilot valve 43. Hydrogen in the main gas chamber 425 is discharged through the second side hole 4221 into the pilot valve 43, and hydrogen in the pressure chamber 426 is discharged through the first side hole 4212 and the throttle 44 into the pilot valve 43. 3. Discharge: Due to the throttle 44 blocking the hydrogen in the pressure chamber 426, the discharge rate of hydrogen in the main gas chamber 425 is much greater than that in the pressure chamber 426. The gas pressure in the pressure chamber 426 is greater than that in the main gas chamber 425. The valve core cover 424 is displaced and squeezes the third spring 423. The hydrogen in the main gas chamber 425 is discharged into the outside through the first pressure relief port 4213. As the gas pressure decreases, the pilot valve 43 closes, achieving emergency pressure relief. The heat exchange coil 25 circulates the temperature control medium to ensure that the temperature of the inner tank 22 is constant, avoiding the explosion caused by the rise of hydrogen pressure in a high-temperature environment.
