[0012] The control method of the conveyor cabinet: Step 1: Place the gas cylinder body. The user opens the cabinet door through the smart lock. At this time, the intersection of the two sets of auxiliary positioning lights is the placement position of the gas cylinder body. After the gas cylinder body is moved to the intersection, the transmission rod, support rod and connecting rod can be rotated by the first motor, worm and worm gear. At the same time, the connecting rod is extended by the first electric push rod until the chuck at one end of the fixed head is on both sides of the gas cylinder body. The chuck can fix the gas cylinder body by rotating the threaded fixing rod. Then, the output end of the first motor is controlled to rotate in the opposite direction. At this time, the gas cylinder body can be lifted and incorporated into the interior of the cabinet through the worm, worm gear, transmission rod, support rod, connecting rod and fixed head. Step 2: Fixing: The second electric push rod is used to make the support plate fit tightly with the bottom end of the gas cylinder body, while also being able to fix and support the gas cylinder body; Step 3: Sealing, the two sets of first threaded rods are driven to rotate by the dual-axis motor, and the first threaded rods and threaded sleeves are used to simultaneously move the movable plates toward one end closer to each other until the movable plates are tightly fitted against the outer wall of the gas cylinder body, and the two sets of movable plates are also tightly fitted; Step 4: If the interior of the gas cylinder body contains toxic or corrosive gas, the user removes the placement box by the handle, places a suitable reaction purifier inside the placement box, and then connects the connecting pipe assembly to the gas cylinder body, and then closes the cabinet door. At this time, the upper and middle part of the cabinet is in a sealed state. After the installation is completed, the internal gas at the top of the fixed sealing plate can be circulated internally by the circulating fan, and the gas in the upper and middle part of the cabinet is monitored in real time by the first intelligent detection sensor. Leakage monitoring can also be performed by the second intelligent detection sensor. When gas leaks, the first and second intelligent detection sensors can control the intelligent control display to sound an alarm, thereby reminding the user to close the solenoid valve at the connection between the connecting pipe assembly and the gas cylinder body through the intelligent control display, cut off the gas supply, and react the leaked gas with the reaction purifier through internal circulation, thereby reducing the content of the leaked gas. Step 5: If the interior of the gas cylinder body contains flammable gas, the movable plate does not need to be closed at this time, so that the interior of the cabinet is in a whole. At the same time, the arc sealing plate is opened by the second motor and the second threaded rod to ensure that the internal air of the cabinet can flow. At the same time, the ventilation fan can increase the speed of exchange between the air inside the cabinet and the outside air. At the same time, the second intelligent detection sensor can also effectively detect gas leakage.

[0013] Compared with the prior art, the present invention has the following beneficial effects: When the user uses this device, the user opens the cabinet door through the smart lock. At this time, the intersection of the two sets of auxiliary positioning lights is the placement position of the gas cylinder body. After the user moves the gas cylinder body to the intersection, the transmission rod, support rod and connecting rod can be rotated through the first motor, worm and worm gear. At the same time, the connecting rod can be extended through the first electric push rod until the clamp at one end of the fixed head is on both sides of the gas cylinder body. The rotation trajectory of the support rod can be limited by the limit groove. When the support rod moves and fits the inner wall of the limit groove, the user can fix the gas cylinder body by rotating the threaded fixing rod, and then control the output end of the first motor to rotate in the opposite direction. At this time, the gas cylinder can be The main body is lifted, and the clamping head clamps the top of the gas cylinder main body. At the same time, the connecting rod and the fixed head are connected by a rotating shaft, so that the gas cylinder main body is always in a vertical state. When the support rod drives the connecting rod, the fixed head and the gas cylinder main body to reset and enter the interior of the cabinet, the first electric push rod can be used to retract one end of the connecting rod into the interior of the support rod. When the support rod is reset, the central axis of the gas cylinder main body is also in the center position of the weighted base. The user then controls the second electric push rod to work, and the second electric push rod makes the support plate fit tightly with the bottom end of the gas cylinder main body. At the same time, it can also fix and support the gas cylinder main body. Since the worm and worm gear themselves are self-locking, it can avoid the support rod, connecting rod and gas cylinder main body from shaking, and then the dual-axis motor drives the two groups When the first threaded rod is rotated, the movable plates can be simultaneously moved toward one end close to each other through the first threaded rod and the threaded sleeve until the movable plates are tightly fitted with the outer wall of the gas cylinder body. At this time, the two sets of movable plates are also tightly fitted. The user needs to select a suitable program according to the characteristics of the gas inside the gas cylinder body. If the gas inside the gas cylinder body is toxic or corrosive, the user can pull down one end of the handle to make the fixed block disengage from the buckle groove. At this time, the placement box can be removed, and a suitable reaction purifier can be placed inside the placement box. Then, after connecting the connecting pipe assembly to the gas cylinder body, the cabinet door can be closed. At this time, the upper and middle part of the cabinet is in a sealed state. After the installation is completed, the internal gas at the top of the fixed sealing plate can be circulated internally through the circulating fan, so that The first intelligent detection sensor can be used to monitor the gas in the upper middle part of the cabinet in real time, and the second intelligent detection sensor can also be used to monitor leakage. When gas leakage occurs, the first intelligent detection sensor and the second intelligent detection sensor can control the intelligent control display to issue an alarm to remind the user. At the same time, the intelligent control display closes the solenoid valve at the connection between the connecting pipe assembly and the gas cylinder body to cut off the gas supply. At the same time, the leaked gas is reacted with the reaction purifier through internal circulation to reduce the content of the leaked gas, thereby improving the safety of user use and preventing the leaked gas from being discharged into the room. If the interior of the gas cylinder body is flammable gas, the movable plate does not need to be closed at this time, so that the interior of the cabinet is in an integrated state.At the same time, the arc sealing plate is opened by the second motor and the second threaded rod, ensuring that the air inside the cabinet can flow. At the same time, the ventilation fan can increase the speed of exchange between the air inside the cabinet and the outside air, thereby improving the safety of the device. At the same time, the second intelligent detection sensor can also effectively detect gas leaks, further improving the safety of the device. When the external power is cut off, the backup battery can continue to provide power to the device, thereby preventing the device from being unusable due to power outage. The device can automatically move the gas cylinder body to the inside of the cabinet, reducing the user's workload and facilitating user use. At the same time, the device can also select appropriate programs according to different gases, further improving the user's convenience and increasing the applicability of the device, reducing its limitations, and providing users with diversity.

The user opens the cabinet door 2 through the smart lock 3. At this time, the intersection illuminated by the two sets of auxiliary positioning lights 18 is the placement position of the gas cylinder body 8. After the gas cylinder body 8 is moved to the intersection, the transmission rod 20, the support rod 12 and the connecting rod 13 can be rotated by the first motor 22, the worm 23 and the worm gear 21. At the same time, the connecting rod 13 is extended by the first electric push rod 17 until the chuck 15 at one end of the fixed head 14 is on both sides of the gas cylinder body 8. The chuck 15 can fix the gas cylinder body 8 by rotating the threaded fixing rod 16. Then, the output end of the first motor 22 is controlled to rotate in the opposite direction. At this time, the gas cylinder body 8 can be lifted and incorporated into the interior of the cabinet 1 through the worm 23, the worm gear 21, the transmission rod 20, the support rod 12, the connecting rod 13 and the fixed head 14; Step 2: Fixing: The second electric push rod 25 is used to make the support plate 26 fit tightly with the bottom end of the gas cylinder body 8, while also being able to fix and support the gas cylinder body 8; Step 3: Sealing, the two sets of first threaded rods 31 are driven to rotate by the dual-axis motor 30, and the first threaded rods 31 and the threaded sleeves 32 are used to simultaneously move the movable plates 28 toward one end closer to each other until the movable plates 28 are tightly fitted against the outer wall of the gas cylinder body 8. At this time, the two sets of movable plates 28 are also tightly fitted; Step 4: If the interior of the gas cylinder body 8 contains toxic or corrosive gas, the user removes the placement box 38 through the handle 40, places a suitable reaction purifier 39 inside the placement box 38, and then connects the connecting pipe assembly 7 to the gas cylinder body 8, and then closes the cabinet door 2. At this time, the middle and upper part of the cabinet 1 is in a sealed state. After the installation is completed, the internal gas at the top of the fixed sealing plate 27 can be circulated internally by the circulating fan 35, and the gas in the middle and upper part of the cabinet 1 is monitored in real time by the first intelligent detection sensor 36.

At the same time, the ventilation fan 48 can increase the speed of exchange between the internal air of the cabinet 1 and the outside air. At the same time, the second intelligent detection sensor 37 can also effectively detect gas leakage.

[0018] When the user uses this device, the user opens the cabinet door 2 through the smart lock 3. At this time, the intersection of the two sets of auxiliary positioning lights 18 is the placement position of the gas cylinder body 8. After the user moves the gas cylinder body 8 to the intersection, the output end of the first motor 22 drives the worm 23 to rotate, and the worm 23 drives the worm wheel 21 and the transmission rod 20 to rotate, and the transmission rod 20 drives the support rod 12 and the connecting rod 13 to rotate. At the same time, the first electric push rod 17 can extend the connecting rod 13 until the clamp 15 at one end of the fixed head 14 is on both sides of the gas cylinder body 8. The rotation trajectory of the support rod 12 can be limited by the limiting groove 11. When the support rod 12 moves and fits the inner wall of the limiting groove 11, the support rod 12 and the connecting rod 13 move to the maximum position, and the user Rotating the threaded fixing rod 16 can make the chuck 15 approach the gas cylinder body 8 until the gas cylinder body 8 is fixed, and then the output end of the first motor 22 is controlled to rotate in the opposite direction. At this time, the transmission rod 20 is rotated through the worm 23 and the worm gear 21, and the transmission rod 20 drives the support rod 12, the connecting rod 13 and the fixed head 14 to reset. At this time, the gas cylinder body 8 is lifted by the support rod 12 and the connecting rod 13. Since the chuck 15 clamps the top of the gas cylinder body 8, and the connecting rod 13 and the fixed head 14 are connected by a rotating shaft, the gas cylinder body 8 is always in a vertical state. The support rod 12 drives the connecting rod 13, the fixed head 14 and the gas cylinder body 8 to reset and enter the interior of the cabinet 1. At the same time, the output end of the first electric push rod 17 is shortened, so that the connecting rod 13, the fixed head 14 and the gas cylinder body 8 are reset. One end of the connecting rod 13 is retracted into the inside of the support rod 12. When the support rod 12 is reset, the central axis of the gas cylinder body 8 is also at the center position of the weighted base 9. The user then controls the second electric push rod 25 to work. The output end of the second electric push rod 25 is extended, which can make the support plate 26 fit tightly with the bottom end of the gas cylinder body 8. At the same time, it can also fix and support the gas cylinder body 8. Since the worm 23 and the worm wheel 21 themselves have self-locking properties, the support rod 12, the connecting rod 13 and the gas cylinder body 8 can be prevented from shaking. The output end of the dual-axis motor 30 drives the two groups of first threaded rods 31 to rotate. The rotating first threaded rod 31 can drive the threaded sleeve 32 to move, and the threaded sleeve 32 can make the movable plate 28 move to one end close to each other at the same time. Move until the movable plate 28 fits tightly against the outer wall of the gas cylinder body 8. At this time, the two sets of movable plates 28 also fit tightly. The user needs to select an appropriate program according to the characteristics of the gas inside the gas cylinder body 8. If the gas inside the gas cylinder body 8 is toxic or corrosive, the upper part of the cabinet 1 needs to be sealed to form an internal circulation of the air inside, thereby purifying it. The user can make the fixing block 42 disengage from the buckle groove 41 by pulling down one end of the handle 40. At this time, the placement box 38 can be removed, and a suitable reaction purifier 39 can be placed inside the placement box 38, and then placed inside the circulator 33. Then, after connecting the connecting pipe assembly 7 and the gas cylinder body 8, the cabinet door 2 is closed. At this time, the upper and middle part of the cabinet 1 is in a sealed state. After the installation is completed,The circulation fan 35 is started, and the air at the top of the fixed sealing plate 27 enters the circulator 33 through the circulation air port 34 at one end of the circulator 33. The circulation fan 35 provides power for air circulation, passes through the reaction purifier 39 inside the placement box 38, and is finally ejected through the circulation air port 34 at the other end of the circulator 33, thereby forming an internal air circulation. The gas in the upper and middle part of the cabinet 1 is monitored in real time by the first intelligent detection sensor 36, and leakage monitoring can also be performed by the second intelligent detection sensor 37. When gas leakage occurs, the first intelligent detection sensor 36 and the second intelligent detection sensor 37 can control the intelligent control display 4 to issue an alarm to remind the user. At the same time, the intelligent control display 4 closes the solenoid valve at the connection between the connecting pipe assembly 7 and the gas cylinder body 8 to cut off the gas supply. At the same time, the leaked gas reacts with the reaction purifier 39 through the internal circulation, thereby reducing the content of the leaked gas, thereby improving the safety of the user and preventing a large amount of leaked gas from being discharged into the room. If the interior of the gas cylinder body 8 is flammable gas, the movable plate 28 There is no need to close it, so that the interior of the cabinet 1 is in a whole. The output end of the second motor 47 drives the second threaded rod 46 to rotate. The rotating second threaded rod 46 can separate the two sets of arc sealing plates 45, so that the arc sealing plates 45 are opened by the second motor 47 and the second threaded rod 46, ensuring that the air inside the cabinet 1 can flow. At the same time, the ventilation fan 48 can increase the speed of exchange between the air inside the cabinet 1 and the outside air, thereby improving the safety of the use of this device. At the same time, the second intelligent detection sensor 37 can also effectively detect gas leaks, further improving the safety of the use of this device. When the external power is cut off, the backup battery 10 can continue to provide power to the device, thereby avoiding the device being unable to be used due to power outage. The device can automatically move the gas cylinder body 8 to the interior of the cabinet 1, reducing the user's workload and facilitating the user's use. At the same time, the device can also select appropriate programs according to different gases, further improving the convenience of user use and increasing the applicability of the device, reducing its limitations in use, and providing diversity for users.
