Description

Technical Field

[0001] This invention relates to the field of explosion-proof storage tank technology, specifically a temporary explosion-proof hydrogen storage tank. Background Technology

[0002] Temporary explosion-proof hydrogen storage tanks are specially designed containers for storing hydrogen. They are designed to ensure the safety of hydrogen during temporary storage and prevent explosions caused by hydrogen leakage, accumulation, or accidental ignition. Temporary explosion-proof hydrogen storage tanks are pressure-controlled variable volume (wet gas tank) or variable pressure-controlled constant volume containers specifically designed for storing hydrogen.

[0003] Although many hydrogen storage tanks utilize high-strength, corrosion-resistant materials such as 316L stainless steel or alloys, these materials can still experience stress corrosion and hydrogen embrittlement after prolonged contact with hydrogen. This can affect the strength and safety of the tank. Cylinders made of ordinary steel have a lower hydrogen weight percentage at higher storage pressures, limiting their storage efficiency and potentially increasing safety hazards. Design flaws in hydrogen storage tanks, such as structural instability or poor sealing at interfaces, can lead to accidents such as hydrogen leaks or explosions.

[0004] In the use of existing hydrogen storage tanks, when hydrogen is compressed and stored in a high-pressure tank, if the tank material cannot withstand the internal high pressure, or if the tank has defects (such as cracks or corrosion), it may rupture. In this case, the high-pressure hydrogen will be released rapidly, forming a shock wave and causing an explosion. The power of this explosion depends on the pressure and temperature of the hydrogen inside the tank, as well as the material and structure of the tank. Furthermore, in the use of existing hydrogen storage tanks, there is a tendency to directly release pressure when the pressure is too high. This causes rapid venting of hydrogen, increasing the risk of explosion, because rapid gas flow may generate static electricity or frictional sparks, thereby triggering an explosion. Summary of the Invention

[0005] To address the problems in the prior art, the present invention provides a temporary explosion-proof hydrogen storage tank.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a temporary explosion-proof hydrogen storage tank, including an outer shell, a first frame fixedly connected to the upper end of the outer shell, an unfolding mechanism provided on the surface of both ends of the outer shell, a pressure relief mechanism provided at one end of both ends of the outer shell near the unfolding mechanism, a dilution mechanism provided on the surface of the outer shell, and a sealing cloth fixedly connected to one end of the outer shell.

[0007] Preferably, a first circular hole is provided on the surface of the outer shell, a carbon fiber rubber is fixedly connected to one end of the outer shell, the outer shell is fixedly connected to both sides of the carbon fiber rubber, and a rubber tube is fixedly connected to the surface of the outer shell.

[0008] Preferably, an air core is fixedly connected to the upper end of the first frame.

[0009] Preferably, the unfolding mechanism includes a first movable frame, the surface of which is fixedly connected to the outer shell, a hollow groove is formed inside the first movable frame, a second circular hole is formed on the side of the first movable frame near the outer shell, a third circular hole is formed on the side of the first movable frame away from the outer shell, a rotating shaft is rotatably connected to one end of the first movable frame, the rotating shaft passes through carbon fiber rubber and is fixedly connected thereto, a second movable frame is rotatably connected to the surface of the rotating shaft, a torsion spring is sleeved on the outside of the rotating shaft, and the first movable frame and the second movable frame are elastically connected by the torsion spring.

[0010] Preferably, the pressure relief mechanism includes a sliding block, which is slidably connected to a hollow groove in the first movable frame, and a pull rope is fixedly connected to the surface of the sliding block.

[0011] Preferably, the dilution mechanism includes an arc-shaped block, the surfaces of multiple arc-shaped blocks are fixedly connected to the outer shell, both ends of the arc-shaped blocks are fixedly connected to the first movable frame, a spring is fixedly connected to the inner surface of the arc-shaped block, and one end of the spring is fixedly connected to the sliding block.

[0012] The beneficial effects of this invention are:

[0013] (1) The hydrogen temporary explosion-proof storage tank of the present invention uses multiple arc-shaped blocks set on the outer surface of the shell to play a role in buffering and shock absorption. At the same time, a certain pressure of inert gas carbon dioxide can be filled into the multiple arc-shaped blocks. Since the arc-shaped blocks are set in a wave shape on the outer surface of the shell, the arc-shaped blocks can also play a role in anti-slip, avoiding the damage caused by sliding and collision during the transportation of the shell, and indirectly improving the explosion-proof effect of the explosion-proof storage tank.

[0014] (2) The hydrogen temporary explosion-proof storage tank of the present invention connects multiple shells with carbon fiber rubber through a set structure, which can be folded, improves its temporaryity, and facilitates quick carrying. The corners of the two shells are sealed with sealing cloth to form a sealed space that can be opened when the multiple shells are opened. The space between the sealing cloth and the corners of the two shells is used to release pressure and store hydrogen, so as to avoid the hydrogen pressure inside the shells being too high and causing an explosion. In this way, the angle formed by the opening of multiple shells can release the internal hydrogen pressure, and at the same time, the sealing cloth can be opened to store hydrogen. At the same time, the opening of multiple shells can also serve as a warning, indicating that the internal pressure is too high and needs to be released in time. The larger the angle of the opening of multiple shells, the greater the internal hydrogen pressure.

[0015] (3) The hydrogen temporary explosion-proof storage tank of the present invention adopts a structure that automatically depressurizes when the hydrogen pressure inside the sealing cloth is too high when the outer shell is unfolded to a certain angle, and automatically releases the hydrogen inside the outer shell into the outside air. When the sliding block moves away from the second round hole, the hydrogen pressure inside the outer shell will be released into the outside air through the third round hole to avoid explosion. At the same time as the sliding block moves away from the first movable frame, the sliding block will also move away from the contact with the arc block. At this time, the inert gas carbon dioxide inside the arc block will be ejected from the third round hole. The carbon dioxide ejected from the third round hole will dilute the hydrogen ejected from the third round hole, avoiding the risk of explosion that may be increased by the rapid discharge of hydrogen. Because rapid gas flow may generate static electricity or friction sparks, thereby causing an explosion. Hydrogen is a flammable gas. When hydrogen is diluted by inert gas carbon dioxide, it will not explode. When the hydrogen flow rate inside the outer shell is too high at the beginning, as more hydrogen is ejected, the internal pressure decreases, and the flow rate of hydrogen ejected from the outer shell also decreases.

Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0031] like Figures 1-12 As shown, the present invention discloses a temporary explosion-proof hydrogen storage tank, comprising an outer shell 100, a first frame 200 fixedly connected to the upper end of the outer shell 100, an unfolding mechanism 300 provided on both ends of the outer shell 100, a pressure relief mechanism 400 provided at one end of the outer shell 100 near the unfolding mechanism 300, a dilution mechanism 500 provided on the surface of the outer shell 100, and a sealing cloth 600 fixedly connected to one end of the outer shell 100. Multiple outer shells 100 are connected by carbon fiber rubber 101 through the structure, allowing them to be folded. The unfolding of the multiple outer shells 100 forms an angle that can relieve the internal hydrogen pressure. Simultaneously, the sealing cloth 600 can be unfolded to store hydrogen. The unfolding of the multiple outer shells 100 also serves as a warning; the larger the unfolding angle of the multiple outer shells 100, the greater the internal hydrogen pressure. With the structure, when the hydrogen pressure inside the sealing cloth 600 becomes too high after the outer shell 100 is unfolded to a certain angle, the pressure will automatically be released, automatically releasing the hydrogen inside the outer shell 100 into the outside air.

[0032] Preferably, the outer shell 100 has a first circular hole 1001 on its surface, a carbon fiber rubber 101 is fixedly connected to one end of the outer shell 100, the outer shell 100 is fixedly connected to both sides of the carbon fiber rubber 101, and a rubber tube 102 is fixedly connected to the surface of the outer shell 100.

[0033] Preferably, a gas core 201 is fixedly connected to the upper end of the first frame 200; hydrogen is introduced into the interior of the outer shell 100 through the gas core 201, and the interior of the arc-shaped block 501 is filled with inert gas carbon dioxide.

[0034] Preferably, the unfolding mechanism 300 includes a first movable frame 301, the surface of which is fixedly connected to the outer shell 100. A hollow groove 3011 is formed inside the first movable frame 301. A second circular hole 3012 is formed on the side of the first movable frame 301 near the outer shell 100, and a third circular hole 3013 is formed on the side of the first movable frame 301 away from the outer shell 100. A rotating shaft 302 is rotatably connected to one end of the first movable frame 301. The rotating shaft 302 passes through and is fixedly connected to the carbon fiber rubber 101. A second movable frame 303 is rotatably connected to the surface of the rotating shaft 302. A torsion spring is sleeved on the outside of the rotating shaft 302. The first movable frame 301 and the second... The movable frame 303 is elastically connected by a torsion spring; the first movable frame 301 and the second movable frame 303 are fixedly connected to the side surfaces of the two outer shells 100. The first movable frame 301 and the second movable frame 303 are elastically connected by a torsion spring, which can tightly fit the two outer shells 100 together. The angle between the two outer shells 100 is sealed by a sealing cloth 600, forming a sealed space that can be opened when multiple outer shells 100 are deployed to release pressure and store hydrogen, preventing excessive hydrogen pressure inside the outer shells 100 from causing an explosion. The rubber tubes 102 on the surfaces of the two outer shells 100 will then fit tightly together. When the hydrogen pressure inside the outer shells 100 reaches a certain pressure, the hydrogen inside will... The gas will flow out from the rubber tube 102 and enter the space between the sealing cloth 600 and the two outer shells 100. At this time, the outer shells 100 will unfold. The unfolding of the two closely fitting outer shells 100 will cause the rubber tube 102 on their surface to move away, so that the hydrogen gas inside the outer shell 100 will be discharged from the rubber tube 102 and enter the space between the sealing cloth 600 and the outer shells 100. Through the designed structure, multiple outer shells 100 are connected by carbon fiber rubber 101, which makes them foldable, improves their temporaryity, and facilitates quick carrying. The side surfaces of the two outer shells 100 are fixedly connected to the first movable frame 301 and the second movable frame 303, which are elastically connected by torsion springs. The two outer shells 100 are tightly fitted together, and the angle between the two outer shells 100 is sealed by a sealing cloth 600, forming a sealed space that can be opened when multiple outer shells 100 are opened. The angle between the sealing cloth 600 and the two outer shells 100 is used to release pressure and store hydrogen, preventing excessive hydrogen pressure inside the outer shells 100 from causing an explosion. In this way, the angle formed by the opening of multiple outer shells 100 can release the internal hydrogen pressure, and at the same time, the sealing cloth 600 can be opened to store hydrogen. In addition, the opening of multiple outer shells 100 can also serve as a warning, indicating that the internal pressure is too high and needs to be released in time. The larger the angle of the opening of multiple outer shells 100, the greater the internal hydrogen pressure.

[0035] Preferably, the pressure relief mechanism 400 includes a sliding block 401, which is slidably connected to the hollow groove 3011 in the first movable frame 301. A pull rope 402 is fixedly connected to the surface of the sliding block 401. When the two outer shells 100 are unfolded, the pull rope 402 will be taut. When the unfolding angle of the two outer shells 100 continues to increase, the pull rope 402 will pull the sliding block 401 to slide outward from the first movable frame 301. The sliding of the sliding block 401 to the first movable frame 301 will stretch the spring 502, and the sliding of the sliding block 401 to the first movable frame 301 will move it away from the second circular hole 3. 012, the third circular hole 3013, at this time, the hydrogen gas inside the outer shell 100 will be discharged through the first circular hole 1001. The hydrogen gas discharged through the first circular hole 1001 will then pass through the second circular hole 3012 and the third circular hole 3013 to exit the tank. At this time, the inert gas carbon dioxide inside the arc-shaped block 501 will also be discharged from the tank through the third circular hole 3013. The inert gas carbon dioxide can dilute the rapidly discharged hydrogen gas, further avoiding the possibility of hydrogen explosion; the structure is designed so that when the hydrogen pressure inside the sealing cloth 600 is too high when the outer shell 100 is unfolded to a certain angle, it will automatically depressurize, and the outer shell 100 will be closed. The hydrogen gas inside the casing 100 is automatically released into the outside air. When the angle between the multiple outer casings 100 expands to a certain angle, the pull rope 402 will taut. As the angle continues to increase, the pull rope 402 will pull the sliding block 401 away from the first movable frame 301. At this time, the sliding block 401 moves away from the second circular hole 3012, and the hydrogen pressure inside the casing 100 will be released into the outside air through the third circular hole 3013 to prevent an explosion. At the same time as the sliding block 401 moves away from the first movable frame 301, the sliding block 401 will also move away from its contact with the arc-shaped block 501. At this time, the inertia inside the arc-shaped block 501... Carbon dioxide gas will be ejected from the third circular hole 3013. The carbon dioxide ejected from the third circular hole 3013 will dilute the hydrogen gas ejected from the third circular hole 3013, preventing the rapid discharge of hydrogen gas from increasing the risk of explosion. This is because rapid gas flow may generate static electricity or frictional sparks, which could trigger an explosion. Hydrogen gas is flammable, but it will not explode when diluted by the inert gas carbon dioxide. If the flow rate of hydrogen gas ejected from the third circular hole 3013 inside the outer casing 100 is too high at first, as more hydrogen gas is ejected, the internal pressure decreases, and the flow rate of hydrogen gas ejected from the inner casing 100 also decreases.

[0036] Preferably, the dilution mechanism 500 includes arc-shaped blocks 501. The surfaces of multiple arc-shaped blocks 501 are fixedly connected to the outer shell 100. The two ends of the arc-shaped blocks 501 are fixedly connected to the first movable frame 301. A spring 502 is fixedly connected to the inner surface of the arc-shaped blocks 501. One end of the spring 502 is fixedly connected to the sliding block 401. Multiple arc-shaped blocks 501 are disposed on the outer surface of the outer shell 100. The arc-shaped blocks 501 are hollow inside with a wavy shape on the outer shell surface. The two ends of the arc-shaped blocks 501 are made of hard rubber, and the rest is made of soft rubber, which can expand and contract. The multiple arc-shaped blocks 501 disposed on the outer surface of the outer shell 100 can play a role in buffering and shock absorption. At the same time, a certain pressure of inert gas carbon dioxide can be filled into the multiple arc-shaped blocks 501. Since the arc-shaped blocks 501 are wavy on the outer shell surface, the arc-shaped blocks 501 can also play a role in anti-slip, avoiding the outer shell 100 from sliding and colliding during transportation and causing damage, thereby indirectly improving the explosion-proof effect of the explosion-proof storage tank.

[0037] Working Principle: In use, hydrogen gas is first introduced into the interior of the outer shell 100 through the gas core 201. The arc-shaped blocks 501 are filled with inert carbon dioxide gas. Multiple arc-shaped blocks 501 are set on the outer surface of the outer shell 100. The arc-shaped blocks 501 are hollow inside with a wavy shape on the outer shell surface. The ends of the arc-shaped blocks 501 are made of hard rubber, while the rest is made of soft rubber, which can expand and contract. The multiple arc-shaped blocks 501 on the outer surface of the outer shell 100 can play a role in buffering and shock absorption. At the same time, a certain pressure of inert carbon dioxide gas can be filled into the multiple arc-shaped blocks 501. Since the arc-shaped blocks 501 are wavy on the outer shell surface, they can also play a role in anti-slip, preventing the outer shell 100 from sliding and colliding during transportation and causing damage, thereby indirectly improving the explosion-proof effect of the explosion-proof storage tank.

[0038] Two outer shells 100 are fixedly connected to their side surfaces by a first movable frame 301 and a second movable frame 303. The first movable frame 301 and the second movable frame 303 are elastically connected by a torsion spring, allowing the two outer shells 100 to fit tightly together. The angle between the two outer shells 100 is sealed by a sealing cloth 600, forming a sealed space that can be opened when multiple outer shells 100 are deployed. This space is used to release pressure and store hydrogen, preventing excessive hydrogen pressure inside the outer shells 100 from causing an explosion. The rubber tubes 102 on the surfaces of the two outer shells 100 will then fit tightly together. When the hydrogen pressure inside the outer shells 100 reaches a certain level, the hydrogen will flow out from the rubber tubes 102 and into the space between the sealing cloth 600 and the two outer shells 100. At this point, the outer shells 100 will unfold. The unfolding of the two fitted outer shells 100 will move the rubber tubes 102 away, allowing the hydrogen inside the outer shells 100 to be discharged from the rubber tubes 102 into the space between the sealing cloth 600 and the outer shells 100. This structure... Multiple outer shells 100 are connected by carbon fiber rubber 101, allowing them to be folded, improving their temporary nature and facilitating quick transport. A first movable frame 301 and a second movable frame 303 are fixedly connected to the side surfaces of two outer shells 100. The first movable frame 301 and the second movable frame 303 are elastically connected by a torsion spring, which can tightly fit the two outer shells 100 together. The angle between the two outer shells 100 is sealed by a sealing cloth 600, forming a sealed space that can be opened when the multiple outer shells 100 are unfolded. The angle between the sealing cloth 600 and the two outer shells 100 is used to depressurize and store hydrogen, preventing excessive hydrogen pressure inside the outer shells 100 from causing an explosion. In this way, the angle formed by the unfolding of multiple outer shells 100 can depressurize the internal hydrogen, and at the same time, the sealing cloth 600 can be unfolded to store hydrogen. In addition, the unfolding of multiple outer shells 100 can also serve as a warning, indicating that the internal pressure is too high and needs to be depressurized in time. The larger the angle of unfolding of multiple outer shells 100, the greater the internal hydrogen pressure.

[0039] When the two outer shells 100 are unfolded, the pull rope 402 will be taut. As the unfolding angle of the two outer shells 100 continues to increase, the pull rope 402 will pull the sliding block 401 to slide outward from the first movable frame 301. The sliding block 401 sliding outward from the first movable frame 301 will stretch the spring 502. The sliding block 401 will move away from the second circular hole 3012 and the third circular hole 3013. At this time, the hydrogen gas inside the outer shell 100 will be discharged through the first circular hole 1001. The hydrogen gas discharged through the first circular hole 1001 will... The hydrogen gas exits the tank through the second circular hole 3012 and the third circular hole 3013. At this time, the inert gas carbon dioxide inside the arc-shaped block 501 also exits the tank through the third circular hole 3013. The inert gas carbon dioxide can dilute the rapidly exiting hydrogen gas, further avoiding the possibility of hydrogen explosion. The structure is designed to automatically depressurize when the hydrogen pressure inside the sealing cloth 600 is too high when the outer shell 100 is unfolded to a certain angle, automatically releasing the hydrogen gas inside the outer shell 100 into the outside air. The included angle between the multiple outer shells 100 is unfolded to a certain angle. When the angle increases, the pull rope 402 will become taut. As the angle continues to increase, the pull rope 402 will pull the sliding block 401 away from the first movable frame 301. At this time, the sliding block 401 will move away from the second round hole 3012, and the hydrogen pressure inside the outer shell 100 will be released into the outside air through the third round hole 3013 to prevent an explosion. At the same time as the sliding block 401 moves away from the first movable frame 301, the sliding block 401 will also move away from its contact with the arc-shaped block 501. At this time, the inert gas carbon dioxide inside the arc-shaped block 501 will be ejected from the third round hole 3013. The carbon dioxide ejected from the third circular hole 3013 will dilute the hydrogen ejected from the third circular hole 3013, preventing the rapid discharge of hydrogen from increasing the risk of explosion. This is because rapid gas flow may generate static electricity or frictional sparks, which could trigger an explosion. Hydrogen is a flammable gas, but it will not explode when diluted by the inert gas carbon dioxide. If the hydrogen flow rate inside the outer casing 100 is too high at the beginning, as more hydrogen is ejected, the internal pressure decreases, and the flow rate of hydrogen ejected from the outer casing 100 also decreases.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by the present invention.
