Description

Technical Field

[0001] This invention relates to the field of gas supply system technology, and more particularly to a gas container gas supply system and method. Background Technology

[0002] Specialty gases are widely used in semiconductor manufacturing, biomedicine, aerospace, and chemical synthesis. These gases often possess hazardous properties such as corrosivity, toxicity, flammability, and explosiveness, requiring strict safety regulations for their storage and transportation. Currently, specialty gas supply relies heavily on gas container supply systems. Existing gas container supply systems are mostly fixed structures, only compatible with external connection flanges conforming to a single standard. When application scenarios change or the external flanges follow different standards, the entire gas container supply system needs to be replaced, resulting in poor equipment versatility and increased operating costs.

[0003] Existing gas supply systems often use simple placement or single-bundle fixing methods for gas storage tanks, resulting in insufficient stability. During equipment transportation, installation, or minor external impacts, the tanks are prone to shaking, shifting, or even colliding with internal components, leading to gas leaks and other safety hazards. Furthermore, the systems store various types of specialty gases, each with its own independent delivery path. Current equipment lacks effective compatibility identification mechanisms, making it easy for operators to misalign the tanks with the delivery paths during installation. This can lead to mixed delivery of different specialty gases, causing chemical reactions, equipment damage, and in severe cases, even explosions or poisoning.

[0004] Furthermore, existing gas container supply systems typically use fixed-size clamps or clips to secure gas tanks, making them incompatible with tanks of varying diameters or heights. When changing the type of gas, resulting in a change in tank specifications, it often requires disassembling and replacing the entire securing assembly. This not only increases operational time but also reduces the versatility and turnaround efficiency of the gas container supply system.

[0005] Meanwhile, the existing gas container supply system has insufficient explosion-proof performance. When the gas storage tank explodes due to an accident, the resulting shock wave can easily damage the internal structure of the station. Flames and debris can easily spread towards the operators, causing casualties and secondary damage to the equipment. The isolation and protection between the instrument chamber and the storage chamber is not perfect. Gas leakage in the storage chamber can easily enter the instrument chamber, damage the instrument components, and affect the normal monitoring and control functions of the equipment. Summary of the Invention

[0006] This invention addresses the shortcomings of existing special gas systems, such as poor compatibility of external flanges, unstable fixing of gas storage tanks, easy misconnection of gas delivery, and insufficient safety of explosion-proof pressure relief. By designing a combination of clamping mechanism, adaptation mechanism, adjustment mechanism, and explosion-proof mechanism, the invention achieves the coordination of each mechanism, solves the defects of the prior art, and improves the versatility, stability, and safety of the equipment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A gas container supply system includes a housing, with an instrument chamber and multiple storage chambers on one side of the housing, the instrument chamber being located above the multiple storage chambers;

[0009] Multiple gas storage tanks are placed in multiple storage cavities respectively for storing different special gases;

[0010] Multiple clamping mechanisms are respectively disposed in multiple storage cavities for clamping and fixing the gas storage tank.

[0011] In one possible design, the clamping mechanism includes a retaining ring I, a screw, and four clamping blocks;

[0012] A fixing cylinder is fixed to the top inner wall of the storage cavity, the screw is threadedly engaged with the fixing cylinder, and the bottom end of the screw is rotatably connected to the top of the fixing ring I;

[0013] Two vertical rods are fixed on both sides of the bottom of the fixed ring I. U-shaped seats are fixed on the inner walls of the two opposite sides of the storage cavity. Two rotating shafts I are rotatably connected in the two U-shaped seats. The four clamping blocks are respectively fixedly sleeved on the outer walls of the four rotating shafts I.

[0014] Two clamping blocks within the same U-shaped seat have protrusions fixed at their closest ends. One side of each protrusion has an inclined surface. The bottom end of the vertical rod slides through the U-shaped seat and engages with the inclined surface.

[0015] Specifically, rotating the screw drives the fixing ring I to move down to the shoulder of the gas storage tank to apply pressure, while the vertical rod moves down and squeezes the protrusion through the inclined surface, causing the clamping block to rotate around the rotating shaft I to clamp the gas storage tank from both sides.

[0016] It also includes multiple connectors, and the housing has multiple circular grooves. The multiple storage cavities are all connected to the instrument cavity through the circular grooves, and the connectors are located in the circular grooves.

[0017] The connecting flange is provided with a plurality of clearance grooves on the top of the housing that communicate with the instrument cavity. The connecting flange is located in the clearance grooves and is used to connect with an external flange.

[0018] as well as,

[0019] An adjustment mechanism, located within the clearance groove, is used to adjust the position of the connecting flange so that the connecting flange can be mated with external flanges of different standard systems.

[0020] One possible design also includes an adapter mechanism;

[0021] The adapter mechanism includes multiple slots, pins, and crossbars disposed on the outer wall of the valve handle of the gas storage tank.

[0022] The fixed cylinder is provided with a vertical groove, and a top plate is slidably connected in the vertical groove. The top end of the screw is rotatably connected to the bottom end of the top plate.

[0023] A connecting seat is fixed at one end of the top plate near the gas storage tank. A rotating shaft II is rotatably connected inside the connecting seat. The pin is fixedly sleeved on the outer wall of the rotating shaft II and engages with the slot.

[0024] The inner walls of the two opposite sides of the connecting seat are provided with transverse grooves, and guide rods are fixedly connected in each of the two transverse grooves. The transverse rods are slidably sleeved on the outer walls of the two guide rods.

[0025] The pin has a connected arc-shaped groove and a positioning groove inside, and the crossbar slides in conjunction with the positioning groove or the arc-shaped groove;

[0026] The screw moves downward, causing the pin to move downward and insert into the slot. At this time, the crossbar extends into the positioning groove under the action of spring I, limiting the pin to a horizontal position to lock the valve handle. When the crossbar is pushed into the arc-shaped groove, the pin can rotate to disengage from the slot.

[0027] In one possible design, the adapter mechanism further includes a fixing ring II fixed to the outer wall of the gas outlet end of the gas storage tank;

[0028] The fixing ring II is provided with multiple insertion holes;

[0029] The bottom of the connector is rotatably connected to a mounting ring, and the bottom of the mounting ring is fixed with multiple pressure rods, which are inserted into the insertion hole.

[0030] A push rod is slidably connected inside the pin. One end of the push rod extends into the positioning groove and abuts against the crossbar, while the other end extends to one side of the pin and is fixed with a trapezoidal block.

[0031] When the connector is connected to the outlet of the gas tank and the pressure rod is inserted into the corresponding insertion hole, the pressure rod presses against the inclined surface of the trapezoidal block, drives the push rod to push the crossbar into the arc groove, and causes the pin to rotate and disengage from the slot.

[0032] In one possible design, the plug-in holes of the multiple gas storage tanks are of different shapes, so that the connector can only dock with the gas storage tank storing the specified gas and release the lock on the valve handle.

[0033] In one possible design, the adjustment mechanism includes a lower moving frame, an upper moving frame, and a sliding seat;

[0034] Both the lower moving frame and the upper moving frame are slidably connected within the clearance groove, and the upper moving frame is located on top of the lower moving frame. The sliding directions of the lower moving frame and the upper moving frame are perpendicular to each other.

[0035] The sliding seat is slidably disposed within the lower moving frame and the upper moving frame, and one end of the connecting flange is fixedly inserted through the sliding seat;

[0036] A bidirectional lead screw rotates through the sliding seat, and two pressure rings are threaded to the positive and negative thread sections of the bidirectional lead screw, respectively. The two pressure rings are located at the top of the upper moving frame and the bottom of the lower moving frame, respectively.

[0037] Specifically, after adjusting the position of the connecting flange by cooperating with the sliding seat, the lower moving frame, and the upper moving frame, rotating the bidirectional screw drives the two pressure rings to move towards each other and press against the upper moving frame and the lower moving frame to fix the position of the connecting flange.

[0038] In one possible design, a second door is hinged to the opening of the storage cavity, and a rotating lever is rotatably connected to one side of the second door.

[0039] A U-shaped bracket is fixed on one side of the housing to cooperate with the rotating lever, and a limiting groove is provided in the U-shaped bracket;

[0040] The shell has a slot communicating with the storage cavity on the side away from the second compartment door. A protective plate is installed in the slot. The protective plate is connected to the inner wall of the slot by bolts. The bolts are made of a brittle material with a predetermined fracture strength.

[0041] The protective plate has multiple V-shaped plates fixed to the side facing the storage cavity, which abut against the gas storage tank.

[0042] In one possible design, the protective plate has multiple connecting lugs fixed on the side away from the V-shaped plate. Each connecting lug has a through hole, and a conical ring is fixed in the through hole. The bolt passes through the conical ring.

[0043] The gas tank is bidirectionally fixed by a combination clamping mechanism that applies vertical pressure to the bottle shoulder and clamps it laterally. Gas misconnection is prevented by a linkage adaptation mechanism that uniquely matches the shape of the plug hole and mechanically locks and unlocks the valve handle. Multi-standard flange adaptation is achieved by an X / Y axis modular adjustment mechanism. Safety protection is achieved by an explosion-proof mechanism that features directional pressure relief and self-locking of the storage door.

[0044] The method of using a gas container supply system includes the following steps:

[0045] S1. Loading and fixing of the gas storage tank: Place the gas storage tank into the storage cavity, rotate the screw, and drive the fixing ring I to move down and press the shoulder of the gas storage tank; when the fixing ring I moves down, it drives the vertical rod to squeeze the inclined surface on the clamping block, and drives the four clamping blocks to rotate inward synchronously to horizontally clamp the gas storage tank.

[0046] S2. Connection and Unlocking: Remove the connector from the circular groove and align it with the outlet of the gas tank. Adjust the angle so that the pressure rod at the bottom of the mounting ring aligns with the insertion hole of the fixing ring II on the gas tank. When the connector is connected to the gas tank and the shape of the pressure rod matches the insertion hole, the pressure rod presses against the trapezoidal block to drive the push rod to move, pushing the crossbar into the arc groove to release the limit on the pin. The pin rotates under the action of the torsion spring and disengages from the slot of the valve handle. At this time, rotate the valve handle to open the valve and supply gas. If the pressure rod does not match the insertion hole, the pin remains locked to the valve handle, and the valve cannot be opened.

[0047] S3. Flange Interface Adjustment and Positioning: Based on the position of the external flange, push the lower moving frame and the upper moving frame to slide along the X-axis and Y-axis directions respectively in the clearance groove to align the connecting flange with the external flange; rotate the double-acting screw to drive the two pressure rings to move towards each other and press the upper moving frame and the lower moving frame respectively to lock the position of the connecting flange.

[0048] S4. Emergency pressure relief and protection: When an explosion occurs in the storage cavity and a shock wave is generated, the V-shaped plate is used to guide the shock wave to the empty slot. The shock wave pushes the protective plate to move, and the conical ring in the connecting ear cuts the bolt, causing the protective plate to pop open and relieve pressure. At the same time, the rotating lever is forced to embed into the limiting slot of the U-shaped card seat and lock the second compartment door.

[0049] Beneficial effects: In this invention, by setting up a clamping mechanism, the gas tank in the storage cavity can be clamped and fixed in all directions. The fixing ring I applies pressure to the shoulder of the gas tank from the vertical direction, and the four clamping blocks clamp the middle of the gas tank from the horizontal direction. The bidirectional fixation can effectively prevent the gas tank from shaking or shifting in the storage cavity, avoid gas leakage caused by collision or shaking, and improve the safety of the equipment. The screw in the clamping mechanism is threaded with the fixing cylinder, which can flexibly adjust the height of the fixing ring I to adapt to gas tanks of different specifications and sizes without replacing the entire fixing mechanism, reducing the difficulty of operation and the cost of use. At the same time, the cooperation between the vertical rod and the inclined surface of the protrusion can realize the synchronous clamping of the clamping blocks, ensuring uniform clamping force and further improving the fixation stability.

[0050] In this invention, by setting an adapter mechanism, the connector can be precisely docked with the gas storage tank for storing specific special gases. Different types of gas storage tanks have different shaped insertion holes in their fixing rings II. The connector can only dock with the gas storage tank when the pressure rod matches the insertion hole. At the same time, the pressure rod squeezes the trapezoidal block, drives the push rod to move, releases the pin rod from the valve handle, and opens the valve to deliver gas. If the docking is incorrect, the pressure rod cannot match the insertion hole, the valve handle will always be limited and cannot be opened. This effectively avoids the mixed delivery of different types of special gases, prevents safety accidents such as chemical reactions, equipment damage, and explosions caused by gas mixing, and ensures the accuracy and safety of gas delivery. At the same time, the magnetic attraction between the magnetic ring and the iron sheet layer of the connector can stably house the connector in the circular groove, preventing the connector from shaking and facilitating docking operations.

[0051] In this invention, by setting an adjustment mechanism, the position of the connecting flange can be flexibly adjusted. The vertical arrangement of the lower and upper moving frames, together with the sliding of the sliding seat, enables the position adjustment of the connecting flange in both the X and Y axes. This allows the connecting flange to accurately dock with external flanges of different specifications and spacings without the need to replace the entire gas container supply system, improving the versatility and applicability of the equipment and reducing equipment investment costs. At the same time, the bidirectional screw drives the pressure ring to move in opposite directions, which can stably position the adjusted connecting flange, avoid changes in the position of the connecting flange, ensure the sealing and stability of the docking, and prevent gas leakage.

[0052] In this invention, the protective plate and V-shaped plate can withstand the shock wave generated when the gas storage tank explodes. The V-shaped plate guides the shock wave to the side and rear. Under the action of the shock wave, the protective plate springs open to release pressure, relieving the pressure in the storage cavity and preventing a secondary explosion due to excessive pressure, thus reducing equipment damage. The bolts and conical rings cooperate to cut off in time when subjected to impact force, ensuring that the protective plate can smoothly spring open to release pressure. At the same time, the rotation lever cooperates with the U-shaped card seat limiting groove to firmly lock the second compartment door under the action of the shock wave, blocking flames and debris from rushing towards the operator, protecting the operator's personal safety and avoiding secondary injury.

[0053] This invention solves the problems of poor versatility, unstable gas tank fixing, easy gas delivery errors, and insufficient explosion-proof performance of existing gas container supply systems through the coordinated operation of various mechanisms. It comprehensively achieves multiple technical effects. The device uses a clamping mechanism to fix gas tanks of different specifications in all directions, ensuring stable storage and preventing shaking and leakage. The adapter mechanism enables precise docking of the connector with the designated gas tank, preventing gas mixing and ensuring safe gas delivery. The adjustment mechanism enables bidirectional position adjustment of the connecting flange, adapting to external flanges of different specifications, improving equipment versatility and reducing investment costs. The explosion-proof protection structure provides pressure relief and safety protection in the event of an accidental explosion of the gas tank, protecting personnel and equipment safety.

[0071] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0072] Reference Figure 1 , Figure 2 and Figure 3 In one embodiment, the gas container supply system includes a housing 1 and multiple gas storage tanks 4 located within the housing 1. The multiple gas storage tanks 4 store different special gases, and the appropriate type of special gas can be selected for storage according to actual application requirements, such as corrosive gases, inert gases, and flammable and explosive gases. Each of the multiple gas storage tanks 4 has a valve handle 20 on one side of its outlet end. The valve handle 20 is fixedly connected to a valve inside the outlet end of the gas storage tank 4. By rotating the valve handle 20, the opening and closing of the valve inside the outlet end of the gas storage tank 4 can be controlled, thereby controlling the output and stoppage of the special gas.

[0073] Furthermore, referring to Figure 2 The housing 1 serves as the mounting base for the entire device. One side of the housing has an instrument chamber 2 and multiple storage chambers 3. The instrument chamber 2 is located above the storage chambers 3. The bottom or side walls of the storage chambers 3 have ventilation holes (not shown in the figure) that connect to an explosion-proof exhaust fan mounted on the housing 1. A gas concentration sensor is installed inside the instrument chamber 2 to monitor for leaks of specific gases. The sensor is electrically connected to the controller and an audible and visual alarm. When a gas concentration exceeding the limit is detected, the controller activates the exhaust fan and triggers the alarm. Multiple storage chambers 3 are evenly arranged below the instrument chamber 2. Each storage chamber 3 corresponds to a gas storage tank 4, used to store different special gases, ensuring that different types of special gases are stored in isolation to avoid mixing reactions caused by gas leaks.

[0074] Furthermore, referring to Figures 2-4 To ensure the stability of the gas storage tank 4 within the storage cavity 3, multiple storage cavities 3 are equipped with clamping mechanisms for holding and fixing the gas storage tank 4. Each clamping mechanism corresponds to one gas storage tank 4, enabling omnidirectional clamping and fixing of the gas storage tank 4 to prevent shaking or displacement. The clamping mechanism includes a fixing ring I5 and four clamping blocks 9. The fixing ring I5 has a ring structure, and its inner diameter matches the outer diameter of the shoulder portion of the gas storage tank 4, allowing it to fit against the shoulder of the gas storage tank 4 and apply vertical pressure to the gas storage tank 4. The four clamping blocks 9 are evenly distributed on the inner wall of the storage cavity 3 in a ring array, enabling horizontal clamping of the middle portion of the gas storage tank 4, achieving bidirectional fixing of the gas storage tank 4.

[0075] Furthermore, referring to Figures 2-6The clamping mechanism also includes a fixed cylinder 13 fixed to the inner wall of the top of the storage cavity 3. The inner wall of the fixed cylinder 13 has an internal thread, through which a screw 12 passes. The outer wall of the screw 12 has an external thread that matches the internal thread of the fixed cylinder 13. Through this threaded engagement, the screw 12 can move up and down within the fixed cylinder 13. The bottom end of the screw 12 is rotatably connected to the top of the fixed ring I5, specifically through a bearing, ensuring that when the screw 12 rotates, the fixed ring I5 can move up and down synchronously with the screw 12 without rotating itself. The rotation of the screw 12 controls the raising and lowering of the fixed ring I5. When the fixed ring I5 moves down to the shoulder of the gas tank 4, it applies vertical pressure to the gas tank 4, pressing the bottom of the gas tank 4 tightly against the inner wall of the bottom of the storage cavity 3, thus fixing the gas tank 4 vertically. To ensure the stability of the fixed ring I5 during its lifting and lowering process and to prevent it from shifting, two vertical rods 6 are fixed to both sides of the bottom of the fixed ring I5. The two vertical rods 6 are vertically arranged and symmetrically distributed on both sides of the screw 12. At the same time, the fixed ring I5 is slidably connected to the inner walls of the storage cavity 3 on both sides away from each other through connecting blocks and connecting grooves. The inner walls of the storage cavity 3 on both sides away from each other are provided with vertical connecting grooves. Connecting blocks that match the connecting grooves are fixed to both sides of the fixed ring I5. The connecting blocks slide into the connecting grooves and can slide up and down along the connecting grooves, which guides the lifting and lowering of the fixed ring I5 and ensures that the fixed ring I5 always lifts and lowers in the vertical direction.

[0076] Furthermore, referring to Figures 2-6 U-shaped seats 7 are fixed to the inner walls of the storage cavity 3 on both sides, which are far apart from each other. The two U-shaped seats 7 are symmetrically distributed. Each U-shaped seat 7 is rotatably connected to two rotating shafts I8. The two rotating shafts I8 are vertically arranged and parallel to each other, and rotate on the top and bottom inner walls of the U-shaped seat 7, respectively. Four clamping blocks 9 are fixedly sleeved on the outer walls of the four rotating shafts I8. One end of the clamping block 9 is fixedly connected to the rotating shaft I8 and can rotate synchronously with the rotating shaft I8. The other end of the clamping block 9 has an arc-shaped structure, and its inner wall is provided with anti-slip texture. The anti-slip texture can increase the friction between the clamping block 9 and the outer wall of the gas storage tank 4, improve the stability of clamping, and at the same time prevent the clamping block 9 from scratching the outer wall of the gas storage tank 4. The outer walls of the four rotating shafts I8 are all fitted with torsion springs I10. The two ends of the torsion springs I10 are fixedly connected to the inner wall of the U-shaped seat 7 and the clamping block 9 respectively through spring seats. When the torsion springs I10 are in their natural state, the clamping block 9 is in an inclined state. The distance between the four clamping blocks 9 is greater than the outer diameter of the gas storage tank 4, which makes it easy to put the gas storage tank 4 into the storage cavity 3. When the clamping block 9 is squeezed by external force, it will rotate around the rotating shaft I8. At the same time, the torsion springs I10 deform and generate a reverse elastic force. When the external force disappears, the clamping block 9 can return to its initial position under the elastic force of the torsion springs I10.

[0077] Furthermore, referring to Figures 2-6Within the same U-shaped base 7, two clamping blocks 9 are each fixed with a protrusion at their closest ends. The protrusion has a rectangular structure, and one side of the protrusion has an inclined surface 11 facing the vertical rod 6, gradually tilting away from the gas tank 4 from top to bottom. The bottom end of the vertical rod 6 slides through the U-shaped base 7 and engages with the inclined surface 11. The bottom end of the vertical rod 6 has a hemispherical structure, which reduces the friction between it and the inclined surface 11, facilitating relative sliding between the vertical rod 6 and the inclined surface 11. When the vertical rod 6 moves downward, it presses against the inclined surface 11 of the protrusion. Through the guiding action of the inclined surface 11, the protrusion is pushed to rotate outward, thereby causing the clamping blocks 9 to rotate inward around the pivot I8. All four clamping blocks 9 rotate inward synchronously, gradually approaching the outer wall of the gas tank 4, and finally fitting against the outer wall of the gas tank 4, clamping and fixing the gas tank 4 horizontally. Combined with the vertical fixing of the fixing ring I5, this achieves all-round fixation of the gas tank 4.

[0078] Reference Figure 2 , Figure 3 and Figure 10 It also includes multiple circular grooves 31 disposed within the housing 1. The multiple circular grooves 31 are evenly arranged, with each storage cavity 3 corresponding to one circular groove 31. All storage cavities 3 are connected to the instrument cavity 2 through the circular grooves 31. Each of the multiple circular grooves 31 is provided with a connector 33. The connector 33 has a cylindrical structure, with one end fixedly connected to the metal flexible hose 34 of the gas transmission pipe 39, and the other end provided with an internal thread, which can be threadedly connected to the gas outlet end of the gas storage tank 4 to realize the connection between the gas storage tank 4 and the gas transmission pipe 39, which facilitates the transportation of special gases.

[0079] Furthermore, referring to Figure 6 and Figure 9 To ensure that the corresponding connector 33 can be connected to the designated gas storage tank 4 for storing special gases and to avoid mixing different types of special gases during transport, an adapter mechanism is provided in the storage cavity 3. The adapter mechanism enables precise connection between the connector 33 and the designated gas storage tank 4. Only when the gas storage tank 4 is of the designated type can the connector 33 be connected to the outlet end of the gas storage tank 4, thereby realizing gas transport and effectively avoiding gas transport errors. The adapter mechanism includes multiple slots 21 set on the outer wall of the valve handle 20 and a fixing ring II 36 fixed to the outer wall of the outlet end of the gas storage tank 4. The multiple slots 21 are evenly distributed on the outer wall of the valve handle 20 in a circular array, which can cooperate with the pin 19 to position the valve handle 20. The fixing ring II 36 has a circular structure and is fixedly sleeved on the outer wall of the outlet end of the gas storage tank 4, fixedly connected to the gas storage tank 4, and moves synchronously with the gas storage tank 4.

[0080] Furthermore, referring to Figure 6The adapter mechanism also includes a vertical groove 14 disposed within the fixed cylinder 13. The vertical groove 14 is a vertically oriented rectangular groove formed on the inner wall of the fixed cylinder 13. A top plate 15 is vertically slidably connected within the vertical groove 14. The top plate 15 has a rectangular structure and can slide up and down along the vertical groove 14. The top end of the screw 12 is rotatably connected to the bottom end of the top plate 15, specifically through a bearing, ensuring that when the screw 12 rotates, the top plate 15 can rise and fall synchronously with the screw 12 without rotating itself, while the screw 12 can rotate relative to the top plate 15. The inner ring surface of the fixed ring I5 is provided with a conical or arc-shaped soft pad (such as a rubber pad) that matches the shape of the shoulder of the gas tank 4. When it moves downward, the conical or soft pad can tightly fit and cover the shoulder, increasing the contact area and friction, and achieving reliable vertical positioning of the gas tank 4.

[0081] Furthermore, referring to Figure 4 , Figure 6 and Figure 7 A connecting seat 16 is fixed to one end of the top plate 15 near the gas storage tank 4. The connecting seat 16 has a U-shaped structure with its opening facing the gas storage tank 4. A rotating shaft II 17 is rotatably connected inside the connecting seat 16. The rotating shaft II 17 is horizontally set, and its two ends are rotatably connected to the inner walls of the two sides of the connecting seat 16, respectively. A pin 19 is fixedly sleeved on the outer wall of the rotating shaft II 17. The pin 19 is horizontally set, and one end extends to the outside of the connecting seat 16, which can engage with the groove 21 on the outer wall of the valve handle 20. Through the engagement of the pin 19 with the groove 21, the valve handle 20 can be positioned to prevent the valve handle 20 from rotating erroneously and avoid accidental gas output or interruption of gas delivery. When the fixing ring I5 moves down to clamp and fix the gas tank 4, the screw 12 synchronously drives the top plate 15 to move downward. The top plate 15 drives the connecting seat 16, the rotating shaft II 17 and the pin 19 to move downward simultaneously, so that the pin 19 gradually approaches the valve handle 20 until the pin 19 extends into the groove 21 on the outer wall of the valve handle 20 and engages with the groove 21 to complete the positioning of the valve handle 20. At this time, the valve handle 20 cannot rotate, and the valve in the gas outlet of the gas tank 4 is in the closed state to prevent gas leakage.

[0082] Furthermore, referring to Figure 4 , Figure 7 and Figure 8Two torsion springs II18 are fitted on the outer wall of the rotating shaft II17. These two torsion springs II18 are symmetrically distributed on both sides of the pin 19. The two ends of each torsion spring II18 are fixedly connected to the inner wall of the connecting seat 16 and one side of the pin 19 via spring seats. When the pin 19 is in a horizontal position and engaged with the slot 21, the torsion springs II18 are in a stored state, generating a clockwise elastic force. When the pin 19 is subjected to external force, it can rotate clockwise around the rotating shaft II17, disengaging from the slot 21 and releasing the valve handle 20 from its position. The inner walls of the connecting seat 16 on both sides, which are far apart from each other, are provided with horizontal grooves 22. These horizontal grooves 22 are rectangular grooves in the horizontal direction, and the two horizontal grooves 22 are symmetrically distributed and parallel to the length direction of the pin 19. Guide rods 24 are fixedly connected to both transverse grooves 22. The guide rods 24 are horizontally positioned, with their ends fixedly connected to the inner walls of both sides of the transverse groove 22. A horizontal rod 23 is slidably fitted onto the outer wall of each guide rod 24. The horizontal rod 23 is also horizontally positioned and can slide left and right along the guide rods 24. The guide rods 24 guide the sliding of the horizontal rod 23, ensuring that the horizontal rod 23 always moves horizontally. Springs I 25 are fitted onto the outer walls of both guide rods 24. The two ends of springs I 25 abut against the outer wall of the horizontal rod 23 and one inner wall of the transverse groove 22, respectively. When springs I 25 are in their natural state, they push the horizontal rod 23 towards the gas storage tank 4, ensuring that the horizontal rod 23 always tends to move towards the gas storage tank 4.

[0083] Furthermore, referring to Figures 4-8 The pin 19 has a connected arc-shaped groove 27 and a positioning groove 26. The positioning groove 26 is a horizontal rectangular groove that matches the size of the crossbar 23 and can accommodate one end of the crossbar 23. The arc-shaped groove 27 has an arc-shaped structure and is opened inside the pin 19. It is connected to the positioning groove 26. The curvature of the arc-shaped groove 27 matches the rotation trajectory of the pin 19. When the pin 19 rotates around the pivot II 17, the crossbar 23 can slide along the arc-shaped groove 27. The crossbar 23 slides in conjunction with the positioning groove 26 and the arc-shaped groove 27. When the crossbar 23 extends into the positioning groove 26 under the elastic force of the spring I 25, it can limit the pin 19 and prevent the pin 19 from rotating around the rotating shaft II 17. At this time, the pin 19 is in a horizontal position and engages with the locking groove 21 of the valve handle 20. The torsion spring II 18 is in a stored state. When the crossbar 23 extends into the arc-shaped groove 27 and squeezes the spring I 25, the limiting effect of the crossbar 23 on the pin 19 is released. The pin 19 rotates clockwise under the elastic force of the torsion spring II 18, thereby causing the pin 19 to disengage from the locking groove 21 and releasing the brake on the valve handle 20. At this time, the operator can rotate the valve handle 20 to control the opening and closing of the valve at the outlet of the gas tank 4.

[0084] Furthermore, referring to Figure 3 and Figure 9The adapter mechanism also includes a magnetic ring 32 fixed in the circular groove 31. The magnetic ring 32 has a ring structure and is fixedly embedded in the inner wall of the circular groove 31. The connector 33 is threadedly connected to the gas outlet end of the gas tank 4. The top of the connector 33 is provided with a sheet metal layer, which is fixedly connected to the connector 33. The connector 33 generates a magnetic attraction between the sheet metal layer and the magnetic ring 32, which can stably store the connector 33 in the circular groove 31, preventing the connector 33 from shaking randomly, and facilitating the docking of the connector 33 with the gas outlet end of the gas tank 4. When it is necessary to dock the connector 33 with the gas tank 4, the operator only needs to overcome the magnetic attraction and pull the connector 33 down from the circular groove 31. When docking is completed or disassembly is required, the connector 33 has a tendency to reset under the action of magnetic attraction, making it easy for the operator to push it back and store it in the circular groove 31.

[0085] Furthermore, referring to Figures 7-9 The bottom of the connector 33 is rotatably connected to an installation ring. Multiple insertion rods 38 are fixed to the bottom of the installation ring, arranged vertically and evenly in a circular array. The fixing ring II 36 has multiple insertion holes 37, the number and position of which match the number and position of the insertion rods 38. The insertion rods 38 engage with the insertion holes 37. When the connector 33 is aligned with the outlet of the gas tank 4, the insertion rods 38 can be inserted into the corresponding insertion holes 37, causing the installation ring to abut against the top of the fixing ring II 36, achieving initial positioning of the connector 33 and the gas tank 4, facilitating subsequent threaded connection. The bottom end of the pressure rod 35 extends below the fixing ring II 36 and engages with the trapezoidal block 29 on one side of the pin rod 19, used to drive the push rod 28 to move. A push rod 28 is slidably connected to the pin 19. The push rod 28 is horizontally positioned, with one end extending into the positioning groove 26 and abutting against the crossbar 23. This push rod 28 can push the crossbar 23 into the arc groove 27, releasing the crossbar 23 from limiting the pin 19. The other end of the push rod 28 extends to one side of the pin 19 and is fixed to a trapezoidal block 29. One side of the trapezoidal block 29 has an inclined surface facing the direction of the pressure rod 35, and it has a structure that gradually slopes from top to bottom towards the push rod 28. The pressure rod 35 cooperates with the inclined surface of the trapezoidal block 29. When the pressure rod 35 moves downward, it will squeeze the inclined surface 11 of the trapezoidal block 29. Through the guiding effect of the inclined surface 11, the trapezoidal block 29 and the push rod 28 are driven to move towards the crossbar 23. A spring II 30 is fitted on the outer wall of the push rod 28. The two ends of the spring II 30 are fixedly connected to the trapezoidal block 29 and the pin 19 respectively through spring seats. When the spring II 30 is in its natural state, one end of the push rod 28 is located in the positioning groove 26 and abuts against the crossbar 23, and the trapezoidal block 29 is in its initial position. When the trapezoidal block 29 is pushed by the squeezing force of the pressure rod 35, the spring II 30 will be compressed and generate a reverse elastic force. When the squeezing force of the pressure rod 35 disappears, the push rod 28 and the trapezoidal block 29 can return to their initial positions under the elastic force of the spring II 30.

[0086] The end of the arc groove 27 is provided with a limiting protrusion or recess. When the crossbar 23 is pushed to the end of the arc groove 27, it can be partially engaged to provide additional resistance, preventing the pin 19 from easily rotating when the valve handle 20 is subjected to unexpected forceful twisting, thus enhancing the accidental protection capability of the locked state.

[0087] Specifically, after the gas storage tank 4 is fixed by the clamping mechanism, the operator first confirms the type of special gas stored in the gas storage tank 4, then locates the connector 33 in the circular groove 31 above the storage cavity 3, overcomes the magnetic attraction between the magnetic ring 32 and the iron sheet layer, and pulls the connector 33 downward from the circular groove 31, so that the bottom of the connector 33 gradually approaches the gas outlet end of the gas storage tank 4; during the process of pulling the connector 33, the operator needs to adjust the angle of the connector 33 so that the multiple insertion rods 38 at the bottom of the mounting ring are aligned with the multiple insertion holes 37 in the fixing ring II 36. After the plug rod 38 is aligned with the plug hole 37, continue to pull down the connector 33 and rotate the connector 33 so that the connector 33 is threadedly connected to the gas outlet end of the gas storage tank 4. As the connector 33 rotates, the connector 33 gradually approaches the gas outlet end of the gas storage tank 4, the plug rod 38 gradually inserts into the corresponding plug hole 37, and the mounting ring gradually approaches the top of the fixing ring II 36 until the mounting ring completely abuts the top of the fixing ring II 36. At this time, the connector 33 is threadedly and securely connected to the gas outlet end of the gas storage tank 4, completing the docking of the connector 33 and the gas storage tank 4, which facilitates subsequent gas transmission.

[0088] During the process of the installation ring abutting against the top of the fixing ring II 36, the pressure rod 35 will continue to move downwards. The bottom end of the pressure rod 35 will gradually contact the inclined surface 11 of the trapezoidal block 29 and apply downward pressure to the inclined surface 11. After the inclined surface 11 is subjected to pressure, it will generate a component force in the direction of the push rod 28, driving the trapezoidal block 29 to move in the direction of the push rod 28. The trapezoidal block 29 drives the push rod 28 to move synchronously in the direction of the horizontal bar 23. At this time, the spring II 30 is compressed, generating a reverse elastic force. When the push rod 28 moves in the direction of the horizontal bar 23, it will apply a pushing force to the horizontal bar 23, pushing the horizontal bar 23 to move away from the gas tank 4 along the guide rod 24. The horizontal bar 23 gradually disengages from the positioning groove 26 and enters the arc groove 27, continuing to compress the spring I 25. The spring I 25 is compressed, generating a reverse elastic force.

[0089] When the crossbar 23 is fully inserted into the arc groove 27, the limiting effect of the crossbar 23 on the pin 19 is released. At this time, the torsion spring II 18 returns to its original shape under the elastic force of its own stored force, driving the pin 19 to rotate clockwise around the rotating shaft II 17. One end of the pin 19 gradually disengages from the groove 21 on the outer wall of the valve handle 20, releasing the brake on the valve handle 20. At this time, the operator can rotate the valve handle 20 to control the valve in the outlet of the gas storage tank 4 to open. The special gas in the gas storage tank 4 can enter the gas transmission pipe 39 through the connector 33 to realize gas transmission.

[0090] Conversely, if the operator mistakenly connects the connector 33 to a non-designated type of gas tank 4, the insertion hole 37 in the fixing ring II 36 corresponding to different gas tanks 4 will not match the insertion hole 37 in the fixing ring II 36 of the gas tank 4 due to the different shapes of the insertion holes 37. The pressure rod 35 at the bottom of the connector 33 cannot be inserted into the insertion hole 37, resulting in the mounting ring at the bottom of the connector 33 not being able to abut against the top of the fixing ring II 36. The pressure rod 35 cannot contact the inclined surface 11 of the trapezoidal block 29, and therefore cannot apply pressure to the trapezoidal block 29. The push rod 28 cannot drive the crossbar 23 to move, and the crossbar 23 will always be in the positioning groove 26, limiting the pin 19. The pin 19 will always be engaged with the slot 21 of the valve handle 20, and the valve handle 20 cannot be rotated. The valve in the gas outlet of the gas tank 4 will always be in the closed state, and gas cannot be delivered. This will avoid the phenomenon of incorrect gas delivery and ensure the accuracy and safety of gas delivery.

[0091] Furthermore, referring to Figure 2 , Figure 3 and Figure 10 Multiple gas delivery pipes 39 are fixedly installed within the instrument cavity 2 via several vertical plates. These pipes are evenly arranged, each corresponding to a connector 33 and a gas storage tank 4, for transporting different types of special gases. The gas delivery pipes 39 are independent of each other to prevent gas mixing. Metal hoses 34 are fixed to both the bottom and top of each gas delivery pipe 39. These metal hoses 34 possess good flexibility and pressure resistance, allowing for adjustments to the positions of the connector 33 and connecting flange 40, preventing damage to the gas delivery pipe 39 due to positional changes. The ends of two metal hoses 34 that are furthest apart are fixedly connected to the connector 33 and connecting flange 40, respectively. Each gas delivery pipe 39 is equipped with a solenoid valve and a flow control valve. The solenoid valve controls the flow and disconnection of the gas delivery pipe 39. When the solenoid valve is open, the gas delivery pipe 39 is in a connected state, allowing normal gas delivery; when the solenoid valve is closed, the gas delivery pipe 39 is in a disconnected state, stopping gas delivery. The flow control valve is used to control the gas flow rate in the gas pipeline 39. Operators can adjust the opening of the flow control valve according to actual production needs to achieve precise control of the gas flow rate and meet the needs of different scenarios.

[0092] Furthermore, referring to Figure 2 , Figure 11 and Figure 12The top of the housing 1 is provided with multiple clearance grooves 41 that communicate with the instrument cavity 2. These clearance grooves 41 are evenly arranged, each corresponding to a connecting flange 40 and a gas supply pipe 39. The dimensions of the clearance groove 41 match the dimensions of the connecting flange 40, accommodating the connecting flange 40 and the adjustment mechanism, facilitating the adjustment mechanism's adjustment of the connecting flange 40's position. The connecting flange 40 is housed within the clearance groove 41, connecting to external flanges to facilitate the delivery of special gases to external equipment. The specifications of the connecting flange 40 are compatible with the specifications of the external flange, and its position can be adjusted via the adjustment mechanism to accommodate external flanges of different specification systems.

[0093] Furthermore, referring to Figure 2 , Figure 11 and Figure 12 In order to adjust the position of the connecting flange 40 so that it can be accurately aligned with the external flanges of different standard systems, an adjustment mechanism is provided in the relief groove 41. The spacing of the external flanges of different standard systems is different. By adjusting the position of the connecting flange 40 through the adjustment mechanism, the connecting flange 40 can be precisely aligned with the external flange, ensuring the sealing and stability of the connection and improving the versatility of the equipment.

[0094] Furthermore, referring to Figure 2 , Figure 11 and Figure 12 The adjustment mechanism includes a lower moving frame 42 and an upper moving frame 43 that slide within the clearance groove 41. Both the lower moving frame 42 and the upper moving frame 43 are rectangular frames arranged vertically, with the upper moving frame 43 located at the top of the lower moving frame 42. The lower moving frame 42 can slide along the length direction (X-axis direction) of the clearance groove 41, and the upper moving frame 43 can slide along the width direction (Y-axis direction) of the lower moving frame 42. Through the cooperation of the lower moving frame 42 and the upper moving frame 43, the connecting flange 40 can be adjusted in the X-axis and Y-axis directions. The same sliding seat 44 is slidably provided within the lower moving frame 42 and the upper moving frame 43. The sliding seat 44 is rectangular, and its dimensions match the internal dimensions of the lower moving frame 42 and the upper moving frame 43. The sliding seat 44 can slide along the length direction of the upper moving frame 43 and simultaneously slides along the lower moving frame 42 along with the upper moving frame 43, thereby realizing the movement of the sliding seat 44 in both the X-axis and Y-axis directions. One end of the connecting flange 40 is fixedly inserted through the sliding seat 44 and can move synchronously with the sliding seat 44. Through the cooperation of the sliding seat 44, the lower moving frame 42 and the upper moving frame 43, the connecting flange 40 can be adjusted on the X-axis and Y-axis so that the connecting flange 40 can be accurately connected with external flanges of different standard systems.

[0095] Furthermore, referring to Figure 11 and Figure 12A sliding rod 45 is fixedly inserted inside the sliding seat 44. The sliding rod 45 is vertically arranged. Two pressure rings 46 are slidably sleeved on the outer wall of the sliding rod 45. The two pressure rings 46 are located at the top and bottom of the upper moving frame 43 and the lower moving frame 42, respectively. The pressure rings 46 have an annular structure, and their inner diameter matches the outer diameter of the sliding rod 45, so that they can slide along the sliding rod 45.

[0096] Furthermore, referring to Figure 2 , Figure 11 and Figure 12 A bidirectional lead screw 47 is rotatably inserted inside the sliding seat 44. The bidirectional lead screw 47 is vertically arranged and parallel to the sliding rod 45. The two ends of the bidirectional lead screw 47 are provided with threads of opposite directions (positive and negative thread sections). Two pressure rings 46 are respectively located on the positive and negative thread sections of the bidirectional lead screw 47. Nuts are fixed inside the two pressure rings 46. The internal threads of the nuts match the external threads of the bidirectional lead screw 47. The two pressure rings 46 are threadedly connected to the positive and negative thread sections of the bidirectional lead screw 47 through the nuts. When the bidirectional lead screw 47 rotates, it can drive the two pressure rings 46 to move towards or in opposite directions along the bidirectional lead screw 47.

[0097] Specifically, when connecting flange 40 needs to be connected to external flange, the operator first observes the position and spacing of external flange and determines the direction and distance that connecting flange 40 needs to be adjusted according to the external flange specification system. Then, the operator pushes the lower moving frame 42, causing it to slide along the X-axis direction of the length of the relief groove 41. The lower moving frame 42 drives the upper moving frame 43, the sliding seat 44, and the connecting flange 40 to move synchronously along the X-axis direction, adjusting the position of the connecting flange 40 in the X-axis direction to align it with the external flange in the X-axis direction. After the X-axis adjustment is completed, the operator pushes the upper moving frame 43, causing it to slide along the Y-axis direction of the width of the lower moving frame 42. The upper moving frame 43 drives the sliding seat 44 and the connecting flange 40 to move synchronously along the Y-axis direction, adjusting the position of the connecting flange 40 in the Y-axis direction until the connecting flange 40 is completely aligned with the external flange. At this time, the connecting holes of the connecting flange 40 correspond one-to-one with the connecting holes of the external flange, facilitating the subsequent bolt 50 connection.

[0098] After the position of the connecting flange 40 is adjusted, the operator rotates the double-acting screw 47. As the screw rotates, the two pressure rings 46 are threaded to the positive and negative thread sections of the screw via nuts. Since the pressure rings 46 are fitted onto the sliding rod 45 and are limited by the sliding rod 45, they cannot rotate with the screw. Therefore, the two pressure rings 46 move towards each other along the screw, gradually approaching the upper moving frame 43 and the lower moving frame 42. With the continued rotation of the screw, the two pressure rings 46 continue to move towards each other until they are in close contact with the top of the upper moving frame 43 and the bottom of the lower moving frame 42, respectively. This applies a clamping force to the moving frames and the upper moving frame 43, using friction to position the lower moving frame 42 and the upper moving frame 43 in their current positions, preventing slippage and thus avoiding any change in the position of the connecting flange 40, ensuring the stability of the connection between the connecting flange 40 and the external flange.

[0099] Furthermore, referring to Figure 2 and Figure 11 A corrugated protective cover 48 is fixedly fitted onto the outer wall of the connecting flange 40. The corrugated protective cover 48 has a cylindrical structure and is made of flexible material, possessing good extensibility and protective performance. The bottom of the corrugated protective cover 48 is fixedly connected to the top of the housing 1, serving to protect components of the adjustment mechanism such as the lower moving frame 42, upper moving frame 43, sliding seat 44, and bidirectional lead screw 47. This prevents external dust and debris from entering the adjustment mechanism and affecting its normal operation, while also preventing operators from accidentally touching the moving parts of the adjustment mechanism and causing safety hazards. The top end of the bidirectional lead screw 47 rotates through the corrugated protective cover 48 and extends above it. A knob is fixed to the top end of the bidirectional lead screw 47, facilitating operator rotation and reducing operational difficulty. The knob is located above the corrugated protective cover 48 for easy operation while preventing contamination and damage from external debris.

[0100] Furthermore, referring to Figure 1 , Figure 2 and Figure 10The instrument chamber 2 is hinged with a first door for sealing it. This first door can rotate around its hinge point, allowing the instrument chamber 2 to be opened and closed. When maintenance or repair is required, the operator can open the first door to operate components such as the gas supply pipe 39, solenoid valve, and flow control valve within the instrument chamber 2. When the equipment is operating normally, the first door is closed, protecting the components within the instrument chamber 2 from dust and debris, and preventing gas leakage from spreading to the outside. Multiple storage chambers 3 are each hinged with a second door for sealing the corresponding storage chamber 3. These second doors correspond one-to-one with each storage chamber 3 and can rotate around their hinge points, allowing the storage chamber 3 to be opened and closed. When placing or removing the gas tank 4, the operator can open the corresponding second door. After the gas tank 4 is secured, the second door is closed, protecting the gas tank 4 within the storage chamber 3 from external impacts and preventing gas leakage from spreading to the outside, thus improving equipment safety.

[0101] Furthermore, referring to Figure 4 and Figure 9 The insertion holes 37 inside the multiple gas storage tanks 4 have different shapes. The insertion holes 37 inside the fixing ring II 36 of each type of special gas storage tank 4 have different shapes and match the shape of the pressure rod 35 at the bottom of the corresponding connector 33. This makes it easy for the connector 33 to dock with the gas storage tank 4 that stores the specified gas, further avoiding the confusion of different types of gas and ensuring the accuracy of gas delivery.

[0102] The instrument chamber 2 is also equipped with a controller (not shown in the figure), which is electrically connected to the solenoid valves and flow control valves on each gas pipeline 39. The controller receives external commands or controls the opening and closing of the solenoid valves and the opening degree of the flow control valves in specific gas pipelines according to preset programs, so as to realize the on-demand and quantitative output of specified types of special gases.

[0103] In another embodiment: Refer to Figure 1 and Figures 13-16Each side of the second compartment door is rotatably connected to a rotating lever 49. Multiple U-shaped brackets 51 are fixed to one side of the housing 1, each corresponding to a rotating lever 49. The U-shaped brackets 51 cooperate with the rotating levers 49 to limit the movement of the second compartment door. When the second compartment door is closed, the operator rotates the rotating lever 49, causing it to engage with the U-shaped bracket 51, thus securing the second compartment door in the closed position and preventing accidental opening. The U-shaped bracket 51 has a limiting groove 52, which is arc-shaped and located on the inner wall of the U-shaped bracket 51. The limiting groove 52 cooperates with the rotating lever 49. When the rotating lever 49 engages with the U-shaped bracket 51, one end of the lever 49 engages with the limiting groove 52, thus limiting the rotation of the lever 49 and preventing it from detaching from the U-shaped bracket 51, ensuring the secure positioning of the second compartment door.

[0104] Furthermore, referring to Figure 1 , Figure 2 , Figure 14 and Figure 15 On the side of the shell 1 away from the second compartment door, there are multiple slots 53, each corresponding to a storage cavity 3 and connected to it. A protective plate 54 is installed inside each slot 53. The protective plate 54 is made of high-strength material and has good impact resistance, capable of withstanding the shock wave generated when the gas tank 4 explodes. Multiple V-shaped plates 55 are fixed to one side of the protective plate 54. The V-shaped plates 55 have a V-shaped structure and are evenly distributed on one side of the protective plate 54, extending into the storage cavity 3 and contacting the gas tank 4. This supports the gas tank 4, further improving its stability within the storage cavity 3. Simultaneously, the V-shaped plates 55 can disperse the external force on the gas tank 4, preventing excessive localized stress and damage.

[0105] Furthermore, referring to Figure 15 and Figure 16Multiple connecting lugs 56 are fixed to the side of the protective plate 54 away from the V-shaped plate 55. Each connecting lug 56 has a through hole 57, which is circular in shape and used to accommodate bolts 50. A conical ring 58 is fixed inside the through hole 57. The conical ring 58 is conical in shape and made of high-strength metal material. Its inner wall is conical, facilitating the passage of the bolt 50 and simultaneously cutting it off under impact. The bolt 50, made of a brittle material with a predetermined fracture strength (such as a specific aluminum alloy or scored nylon), passes through the through hole 57. The inner hole of the conical ring 58 has a sharp cutting edge or a reduced diameter structure at the position corresponding to the bolt shank. When the impact force reaches a threshold, the cutting edge or reduced diameter creates concentrated shear on the bolt shank, ensuring it breaks at a predetermined position. Through material selection and structural design, the fracture shear force of the bolt can be matched with the safe pressure relief value of the storage chamber 3, allowing it to be cut off by the conical ring 58 under a certain impact force. Bolt 50 passes through conical ring 58 and is threaded to the inner wall of slot 53. The protective plate 54 is fixed in slot 53 by bolt 50, so that V-shaped plate 55 always contacts gas tank 4 and supports gas tank 4.

[0106] Specifically, when the gas storage tank 4 explodes due to an accident such as collision, corrosion, or excessive pressure, a huge shock wave will be generated instantly inside the storage cavity 3. The shock wave will spread in all directions, first acting on the V-shaped plate 55 and the protective plate 54. The V-shaped plate 55 has a V-shaped structure, which can disperse part of the shock wave's force and guide the shock wave mainly towards the side and rear empty slot 53, avoiding the shock wave directly acting on the second compartment door and the instrument cavity 2, and reducing the damage to other parts of the equipment. When the shock wave acts on the protective plate 54, it will exert a huge thrust on the protective plate 54, pushing the protective plate 54 to move outward of the empty slot 53. The protective plate 54 drives the connecting lug 56 to move synchronously. A conical ring 58 is provided inside the through hole 57. When the thrust on the protective plate 54 reaches a certain value, the connecting lug 56 applies shearing force to the bolt 50 through the conical ring 58. The conical structure of the conical ring 58 can concentrate the shearing force and cut the bolt 50. At this time, the protective plate 54 is pushed open by the thrust of the shock wave and moves to the outside of the slot 53 to relieve pressure. This can effectively alleviate the pressure in the storage cavity 3 and prevent the storage cavity 3 from having a secondary explosion due to excessive pressure. At the same time, it reduces the damage of the shock wave to the shell 1.

[0107] Under the action of the shock wave, the second compartment door will tend to open the storage cavity 3, causing the rotating lever 49 to move outward of the U-shaped bracket 51. At this time, one end of the rotating lever 49 is embedded in the limiting groove 52 of the U-shaped bracket 51. The limiting groove 52 can block the rotating lever 49, preventing the rotating lever 49 from disengaging from the U-shaped bracket 51, thereby ensuring that the second compartment door remains locked and cannot be opened. This physically prevents flames and debris from rushing towards the operator, protecting the operator's personal safety, and at the same time preventing flames and debris from spreading to the outside and causing secondary damage.

[0108] After the explosion accident is dealt with, the operator only needs to replace the cut bolt 50, pass the new bolt 50 through the through hole 57 and conical ring 58 of the connecting lug 56, and thread it into the inner wall of the empty groove 53 to fix the protective plate 54 back into the empty groove 53, so that the V-shaped plate 55 is in contact with the gas storage tank 4 again, restoring the support and explosion-proof function of the protective plate 54. The operation is simple and convenient, and it is easy to quickly restore the equipment to use.

[0109] The method of using a gas container supply system includes the following steps:

[0110] S1. After the operator places the gas storage tank 4 containing the specific special gas into the storage cavity 3, the operator rotates the screw 12. The screw 12, through its threaded engagement with the fixed cylinder 13, drives the fixing ring I5 to move downward. The fixing ring I5 drives the vertical rod 6 to move downward simultaneously. The bottom end of the vertical rod 6 presses against the inclined surface 11 of the protrusion on the clamping block 9. Through the guiding action of the inclined surface 11, the clamping block 9 is pushed to rotate inward around the rotating shaft I8. The torsion spring I10 deforms and generates elastic force. The four clamping blocks 9 simultaneously clamp the middle of the gas storage tank 4 horizontally. At the same time, the fixing ring I5 moves down to fit the shoulder of the gas storage tank 4, applying a vertical clamping force to the gas storage tank 4, pressing the bottom of the gas storage tank 4 tightly against the bottom of the storage cavity 3, achieving all-round fixation of the gas storage tank 4, preventing the gas storage tank 4 from shaking or shifting, and providing a stable foundation for subsequent gas transportation.

[0111] S2. After the gas tank 4 is fixed, the operator pulls the connector 33 in the corresponding circular groove 31 according to the type of gas in the gas tank 4. Overcoming the magnetic attraction between the magnetic ring 32 and the iron sheet layer, the connector 33 moves downward. The angle of the connector 33 is adjusted so that the insertion rod 38 at the bottom of the mounting ring is aligned with the insertion hole 37 in the fixing ring II 36. The connector 33 is rotated so that it is threadedly connected to the gas outlet end of the gas tank 4. The insertion rod 38 is inserted into the insertion hole 37. The mounting ring abuts against the top of the fixing ring II 36. At this time, the pressure rod 35 presses the inclined surface 11 of the trapezoidal block 29, driving the push rod 28 and the trapezoidal block 29 to move towards the horizontal bar 23. The spring II 30 is compressed, and the push rod 28 pushes the horizontal bar 23 to disengage from the positioning groove 26 and enter the arc. Inside slot 27, spring I 25 is compressed, the limit of crossbar 23 on pin 19 is released, torsion spring II 18 returns to its original state, driving pin 19 to rotate clockwise, disengaging from slot 21 of valve handle 20, releasing the brake on valve handle 20. The operator rotates valve handle 20 to open the valve at the outlet of gas tank 4. Special gas enters gas transmission pipe 39 through connector 33, and after being regulated by solenoid valve and flow control valve, it is delivered to external equipment through connecting flange 40 to complete gas transmission. If connector 33 is connected to a non-designated gas tank 4, pressure rod 35 cannot match insertion hole 37, mounting ring cannot abut against fixing ring II 36, pressure rod 35 cannot drive push rod 28 to move, and pin 19 always limits valve handle 20, preventing valve from opening and avoiding gas transmission errors.

[0112] S3. When the external flanges follow different standard systems and their spacing is different, the operator pushes the lower moving frame 42 to slide along the X-axis direction of the clearance groove 41, thereby driving the connecting flange 40 to adjust its X-axis position; pushes the upper moving frame 43 to slide along the Y-axis direction of the lower moving frame 42, thereby driving the connecting flange 40 to adjust its Y-axis position until the connecting flange 40 is completely aligned with the external flange. Then, the operator rotates the bidirectional screw 47 to drive the two pressure rings 46 to move towards each other, respectively abutting against the upper moving frame 43 and the lower moving frame 42. The lower moving frame 42 and the upper moving frame 43 are positioned by friction to prevent the connecting flange 40 from changing position, ensuring that the connecting flange 40 and the external flange are tightly connected, thus achieving compatibility with different standard systems.

[0113] S4. When the gas storage tank 4 explodes unexpectedly, the shock wave generated in the storage cavity 3 first acts on the V-shaped plate 55 and the protective plate 54. The V-shaped plate 55 disperses the shock wave and guides it to the side and rear empty groove 53. After being pushed by the shock wave, the protective plate 54 drives the connecting ear 56 to move. The connecting ear 56 applies shearing force to the bolt 50 through the conical ring 58, cutting the bolt 50. The protective plate 54 pops open to release pressure, relieving the pressure in the storage cavity 3 and preventing a secondary explosion. At the same time, the shock wave pushes the second compartment door to open. The rotating lever 49 is embedded in the limiting groove 52 of the U-shaped card seat 51 to prevent the rotating lever 49 from disengaging, ensuring that the second compartment door is firmly locked, blocking flames and debris from rushing towards the operator, and achieving explosion protection.
