Description

Technical Field

[0001] The present invention relates to the technical field related to medical equipment, and in particular to an intelligently controlled medical gas bus. Background Art

[0002] A medical gas bus is a centralized gas supply device in hospitals. To improve work efficiency and ensure safe production (gas use), it centralizes the gas sources of individual gas supply points and brings together multiple gas containers (high-pressure gas cylinders, cryogenic dewar tanks, etc.) to achieve centralized gas supply. The principle of a gas bus is to input bottled gas into the bus main pipeline through fixtures and hoses, and after pressure reduction and regulation, it is transported to the gas use site through pipelines. Medical gas busses can be divided into gas cylinder busses and cryogenic liquid gas cylinder busses; they are suitable for a variety of gases (liquid nitrogen, liquid ammonia, oxygen, nitrogen, carbon dioxide, nitrous oxide, argon, etc.).

[0003] In existing busbar technology, Chinese patent publication number CN217382540U discloses an automatically switching medical gas busbar, specifically, an automatically switching medical gas busbar. The busbar includes a switching device disposed above a gas delivery device, the gas delivery device including a first bronchus and a second bronchus. In the automatically switching medical gas busbar, when the gas pressure in one gas tank decreases, the pressure of the gas blown from the corresponding gas inlet also decreases. At this time, an indicator rod slowly moves downward, driving a baffle downward via a connecting rod. The baffle moves downward, slowly blocking the opening of one gas inlet, while the baffle on the other side moves upward, opening the gas inlet. This allows for automatic gas switching and allows the relative gas pressure within the gas tank to be determined by the height of the indicator rod. This solves the problem of workers having to first go outside to observe the pressure gauge on the gas tank and then check the pressure at the switching device indoors.

[0004] In the above-mentioned prior art, the relative air pressure in the gas tank is mainly judged by personnel checking the height of the indicator rod. There is no need for personnel to go outdoors to observe the pressure of the instrument on the gas tank, and then go to the switching device indoors to check according to the pressure. In the above-mentioned prior art, personnel need to check the height of the indicator rod frequently. Although there is no need for outdoor observation, personnel also need to be arranged to stay for a long time. In addition, during the output process of the gas in the gas tank, the amount of gas in a single gas tank at one side cannot be detected (when the amount of gas tanks on one side is in multiple groups in the above-mentioned prior art, they are all collectively transported through the same ventilation pipe, and the amount of gas in a single gas tank cannot be detected). If the gas tanks on both sides are in a gas outage state, it is easy for the replacement to be untimely, resulting in a gas outage, causing a safety accident. In the process of replacing the gas tank and the bus body 12, it takes a long time, and it is difficult to ensure the sealing of the docking, which can easily cause leakage of external gas and cause gas pollution. Based on this, there is still room for improvement in the existing bus technology. Summary of the Invention

Annular sliders are provided at the front and rear ends of the rotating column. The annular sliders are rotatably arranged in the arc track opened by the connecting frame. The setting of the connecting frame mainly ensures that the rotating sleeve in the rotating state cannot move forward and backward with the square tube.

[0011] Preferably, the gear set includes gear one, gear two, bevel gear three, bevel gear four, a connecting rod, and a connecting gear. Gear one that cooperates with rack two is installed on shaft one, and shaft one is rotatably arranged inside the shell. Gear two that cooperates with gear one is installed in the middle of shaft two. Gear one and gear two have the same diameter. Shaft two is rotatably arranged inside the shell. Bevel gear three is installed on the front side of the middle of shaft two. Bevel gear four that cooperates with bevel gear three is installed at the lower end of the connecting rod. Bevel gear three and bevel gear four have the same diameter. The middle part of the connecting rod in an upright state is rotatably arranged at the upper end of the shell. A connecting gear is installed at the upper end of the connecting rod. The connecting gear is meshed with rack one, and the diameter of rack one is larger than the diameter of the connecting gear, which plays the role of speed difference.

[0012] Preferably, the rotating assembly includes a motor, a transmission shaft, and a fixed frame. The motor is provided at the upper end of the mounting plate, the protruding end of the motor is connected to the transmission shaft, the transmission shaft and the fixed frame are rotationally connected, the fixed frame is installed at the lower end of the mounting plate, a rack is provided on the outer edge of the transmission shaft, and a claw head is installed at the lower end of the transmission shaft, and the claw head corresponds to the position of the gas cylinder valve.

[0013] Preferably, the lifting module includes a cylinder, a lifting rod, a buffer plate, and a buffer spring. The cylinder is installed in the installation groove opened in the base, the protruding end of the cylinder is connected to the lifting rod, the lifting rod and the guide sleeve set at the lower end of the buffer plate are slidably connected, and a buffer spring is connected between the lifting rod and the guide sleeve. The lifting module has the function of buffering the positioning module for falling back and resetting and the empty bottle.

[0014] Preferably, the suspension module includes a suspension hook and a return spring. The suspension hook is slidably arranged in a sliding groove opened at the upper end of the side panel. The suspension hook is C-shaped as a whole, and the upper and lower end faces of the suspension hook are provided with inclined surfaces to cooperate with the positioning module. A return spring is connected between the suspension hook and the sliding groove, and the return spring plays a role of elastic return.

[0015] Preferably, the positioning module includes a working plate, a working groove, a clamping piece, a reset assembly, a supporting plate, an extrusion column, an extrusion plate, and a fixing assembly. The left and right side walls of the working plate are provided with a resistance slider, the outer sleeve of the resistance slider is provided with a rubber sleeve, and the resistance slider slides up and down in the lifting slot opened in the side plate, and the resistance slider can control the resistance-increasing descent of the working plate to avoid structural damage caused by empty bottles and positioning modules descending too fast. A working groove is opened in the middle of the working plate, and clamping pieces are symmetrically provided for sliding on the left and right ends of the working groove. A telescopic spring is connected between the clamping pieces, and the clamping piece is engaged with the lower end of the suspension hook. The working plate is elastically connected to the supporting plate through the reset assembly, and an extrusion column is installed in the middle of the lower end of the supporting plate. The extrusion column slides in the extrusion hole opened in the working plate, and extrusion plates are symmetrically installed on the left and right sides of the lower end of the supporting plate. The extrusion plate is extruded and matched with the inclined surface of the upper end of the suspension hook. The upper end of the supporting plate is provided with a placement groove, and the placement groove is rotatably connected to the lower end of the fixing assembly.

[0016] Preferably, the inner inclined surface of the clamping member is a structure that gradually tilts downward from the outside to the inside, and the inclined surface of the clamping member contacts the rounded structure at the lower end of the extrusion column. When the support plate descends under the gravity of the gas cylinder, the distance between the extrusion plate and the clamping member gradually decreases. When the support plate descends to the minimum distance from the working plate, the distance between the extrusion plate and the clamping member is smaller than the distance between the upper and lower ends of the suspension hook. When the jacking module drives the positioning module to rise to the specified position as a whole, the clamping member is clamped with the lower end of the suspension hook. The extrusion plate does not contact the upper inclined surface of the suspension hook at this time. When the gas in the gas cylinder is gradually discharged and the weight of the gas cylinder becomes lighter, the support plate gradually rises under the action of the reset assembly, and the synchronously rising extrusion plate squeezes the upper inclined surface of the suspension hook.

[0017] Preferably, the fixing assembly includes an angle rod and a clamp. The lower end of the angle rod is connected to the side end of the placement slot through a pin shaft, and the angle rod is connected to the placement slot through an extrusion spring.

The lower end of the blocking plate is designed as a frustum, and the inclined surface of the lower end of the blocking plate cooperates with the upper end of the sealing ring to block the connecting pipe, thereby ensuring the internal sealing effect of the connecting pipe when it is not working. The expanded diameter cavity located above the blocking plate is opened inside the connecting pipe.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. The docking module, rotating module and connecting module provided in the present application adopt a structural linkage design concept. For the opening and closing and docking of the gas cylinder, a single drive synchronous execution method is adopted to open the valve of the gas cylinder, dock the extension port of the gas cylinder with the corresponding pipe, and connect the docking pipe with the connecting pipe, so that the gas cylinder placed in the specified position is automatically connected to the gas. Subsequently, for the output of the gas from the gas cylinder, the lifting and lowering of the gas cylinder is controlled by weight detection. When the gas cylinder is empty, the gas cylinder rises to the highest point under the action of elasticity. At this time, the extension port of the gas cylinder is separated from the corresponding pipe, and the gas cylinder descends to the initial position at a low speed under the action of increased resistance, so as to wait for replacement by personnel for regular inspection. The inspection of the gas cylinder is single-bottle inspection, and they can be replaced one by one. Compared with the overall replacement of a row of gas cylinders in the prior art, the replacement of the present application is timely, ensuring the smooth and continuous output of gas. At the same time, through the linkage and cooperation of the positioning module, the purpose of automatically positioning and fixing the gas cylinder is achieved. The functionality of the present application is stronger, the use is more convenient, and the efficiency and safety are greatly improved.

[0021] 2. The present application mainly adopts the elastic support method to conduct real-time monitoring for the detection of the weight of the gas in the gas cylinder. Specifically, when the gas-filled gas cylinder rises to a specified height, the clamping piece is clamped with the lower end of the hanging hook, and the extrusion plate is located below the upper end of the hanging hook (not in contact). As the gas in the gas cylinder is discharged, the weight of the gas cylinder is reduced and it rises under the action of elasticity. The supporting plate and the extrusion plate rise synchronously, and the extrusion plate contacts the inclined surface of the upper end of the hanging hook and squeezes it outward. As the gas in the gas cylinder is completely discharged, the upper end of the hanging hook is squeezed to the outermost side. At this time, the hanging hook and the clamping piece are in a decoupled state. As the subsequent gas cylinder extension port is detached from the corresponding tube, there is no supporting force to support the gas cylinder. Under the action of gravity, the gas cylinder descends to its original position in an increasing resistance manner. At this time, it can be determined that the gas cylinder is empty and needs to be replaced.

[0022] 3. For the docking of gas cylinders and valve control, the design concept of a linkage speed change structure is adopted. Specifically, the motor drives the claw head and rack 1 to rotate synchronously, and the claw head rotates to open the valve of the gas cylinder. At the same time, under the speed change action of multiple sets of gears (rack 1, connecting gear, bevel gear 4, bevel gear 3, gear 2, gear 1), the square tube and the corresponding tube are driven to rotate. Under the action of the threaded connection, the corresponding tube is made to advance in a spiral manner, thereby sealing the protruding port of the gas cylinder and achieving the effect of synchronous control of the valve and the interface. Compared with the existing technology, the sealing performance is improved and the time consumption is shorter. BRIEF DESCRIPTION OF THE DRAWINGS

A support frame 10 is provided at the upper end of the positioning module 8, and a docking module 9 cooperating with the rotation module 4 is installed at the upper end of the support frame 10. A connecting module 11 cooperating with the docking module 9 is installed at the front end of the back panel 2. The connecting module 11 is connected to the bus body 12. The bus body 12 of the existing equipment is installed on the wall at a suitable position, and the card joint 13 set at the front end of the docking module 9 is installed on the support frame 10.

[0035] Reference Figure 1-2 As shown, the rotating module 4 includes a rotating component 41, a claw head 42 and a rack 43. The rotating component 41 is installed on the mounting plate 3. The claw head 42 is installed at the lower end of the rotating component 41. The valve structure of the rising gas cylinder is docked with the claw head 42. The rotation of the claw head 42 is used to control the rotation of the valve, thereby playing the role of a switch. A rack 43 is provided on the edge of the rotating component 41.

[0036] Reference Figure 1-2 、 Figure 7-8 As shown, the docking module 9 includes a shell 91, a fixed tube 92, a docking tube 93, a square tube 94, a rotating sleeve 95, a gear set 96 and a corresponding tube 97. The shell 91 is installed at the upper end of the support frame 10, and a fixed tube 92 is installed at the lower end of the interior of the shell 91. The rear end of the fixed tube 92 is connected to the upright docking tube 93, and the docking tube 93 is slidably arranged in the connecting module 11. The upper end of the docking tube 93 is a frustum design, and vents are evenly opened on the conical surface. The front end of the fixed tube 92 is threadedly connected to the corresponding tube 97, and the corresponding tube 97 is fixedly sleeved inside the square tube 94. The front end of the corresponding tube 97 is provided with a threaded structure that cooperates with the extension port of the gas cylinder valve. A rotating sleeve 95 is horizontally slidably provided on the square tube 94, and the gear set 96 cooperating with the rotating sleeve 95 is rotatably set inside the shell 91. The rotating sleeve 95 is rotatably set on the connecting frame, and the connecting frame is installed at the upper end of the support frame 10.

[0037] By adopting the above technical solution, in actual use, the gas cylinder is placed in the positioning module 8, and the positioning module 8 adjusts and fixes the position of the gas cylinder body. At this time, the extension port of the gas cylinder valve is clamped into the clamping joint 13. At this time, the position of the extension port is opposite to the front end of the corresponding tube 97. The positioning module 8 and the positioned gas cylinder are driven to rise synchronously through the jacking module 5. After the positioning module 8 rises to a specified height, it is clamped with the hanging module 7. Then the jacking module 5 is lowered and reset to disengage from the positioning module 8 (because the positioning module 8 and the hanging module 7 are in a clamped state, they will not follow the decline), and the docking pipe 93 that rises synchronously with the positioning module 8 moves upward and enters the connecting module 11. At this time, the docking pipe 93 is in communication with the busbar body 12, and the gear set 96 that rises synchronously with the docking pipe 93 is meshed with the rack 143. At this time, the gas cylinder valve is stuck in the claw head 42, and the claw head 42 and the rack 143 are driven to rotate synchronously by the rotating component 41. The gear set 96 meshed with the rack 143 drives the rotating sleeve 95 to rotate, and the square tube 94 slidingly arranged inside the rotating sleeve 95 drives the corresponding tube 97 to rotate. Since the corresponding tube 97 is provided with a thread inside, and the thread at the rear end of the corresponding tube 97 is connected with the thread at the front end of the fixed tube 92, the corresponding tube 97 gradually moves forward under the action of the thread rotation. When the corresponding tube 97 moves to the rear end of the extension port of the gas cylinder valve, the thread at the front end of the corresponding tube 97 is connected with the extension port. The thread at the rear end of the outlet is engaged and continues to move forward to the specified position. At this time, the corresponding tube 97 is sealed and docked with the extended port of the gas cylinder. At the same time, the synchronously rotating claw head 42 rotates the gas cylinder valve. At this time, the gas cylinder valve is in an open state, and the gas cylinder and the bus body 12 are successfully connected. The gas in the gas cylinder is transported to the bus body 12, and the bus body 12 transports the gas to the specified area. As the gas in the gas cylinder is output, the weight of the gas cylinder is reduced. At this time, the gas cylinder gradually rises under the action of elasticity. When the gas in the gas cylinder is transported, the gas cylinder rises to the highest position. At this time, the rotating component 41 drives the claw head 42 and the rack 43 to rotate synchronously in the opposite direction, so that the gas cylinder valve is closed and the corresponding tube 97 is closed. , and the protruding port of the gas cylinder is disengaged. At the same time, the positioning module 8 is squeezed and unhooked from the hanging module 7. After unhooking, the positioning module 8 gradually drops to the initial position under the action of the gravity of the gas cylinder, and the connecting pipe 93 and the connecting module 11 that drop synchronously with the positioning module 8 are disconnected, and the connecting module 11 is resealed and blocked. At this time, the air cylinder can be replaced. The present application uses a special design of the docking module 9 to enable automatic docking during the actual replacement of the gas cylinder. The present application adjusts and locks the posture of the gas cylinder through the positioning module 8, thereby reducing the probability of the gas cylinder tipping over. The present application is simple to operate and has a stable structure, which can greatly improve the work efficiency and safety during actual use.

[0038] Reference Figure 7-8As shown, in order to ensure that the square tube 94 can move back and forth in a rotating state, the present application is provided with a rotating sleeve 95. Specifically, the rotating sleeve 95 includes a rotating column 951 and a second rack 952. The inner cavity of the rotating column 951 is a square structure. The outer wall annular sleeve of the rotating column 951 is provided with a second rack 952. The rotating column 951 is an outer circle and inner square structure as a whole. An annular slider is provided at the front and rear ends of the rotating column 951. The annular slider is rotatably set in the arc track opened by the connecting frame. The setting of the connecting frame mainly ensures that the rotating sleeve 95 in the rotating state cannot move back and forth with the square tube 94.

[0039] Reference Figure 1 、 Figure 7-8 As shown, in order to seal and dock the extended port of the gas cylinder while opening the valve of the gas cylinder, the present application performs synchronous execution through the linkage structure design between the rotation module 4 and the docking module 9. The present application is provided with a gear set 96 for this situation. Specifically, the gear set 96 includes gear 1 961, gear 2 962, bevel gear 3 963, bevel gear 4 964, connecting rod 965, and connecting gear 966. Gear 1 961 matched with rack 2 952 is installed on shaft 1, and shaft 1 is rotatably arranged inside the housing 91. Gear 2 962 matched with gear 1 961 is installed in the middle of shaft 2. Wheel one 961 and gear two 962 have the same diameter, shaft two is rotatably set inside the housing 91, bevel gear three 963 is installed on the front side of the middle part of shaft two, bevel gear four 964 that cooperates with bevel gear three 963 is installed at the lower end of connecting rod 965, bevel gear three 963 and bevel gear four 964 have the same diameter, the middle part of the connecting rod 965 in the upright state is rotatably set at the upper end of the housing 91, and a connecting gear 966 is installed on the upper end of the connecting rod 965, and the connecting gear 966 is meshed with rack one 43, and the diameter of rack one 43 is larger than the diameter of the connecting gear 966, which plays the role of speed difference.

[0040] Reference Figure 1-2 、 Figure 4 、 Figure 7-8 As shown, the present application is provided with a rotating assembly 41 for the above situation. Specifically, the rotating assembly 41 includes a motor 411, a transmission shaft 412, and a fixing bracket 413. The motor 411 is provided at the upper end of the mounting plate 3, and the protruding end of the motor 411 is connected to the transmission shaft 412. The transmission shaft 412 and the fixing bracket 413 are rotationally connected. The fixing bracket 413 is installed at the lower end of the mounting plate 3. A rack 43 is provided on the outer edge of the transmission shaft 412, and a claw head 42 is installed at the lower end of the transmission shaft 412. The claw head 42 corresponds to the position of the gas cylinder valve.

[0041] In actual operation, when the positioning module 8 drives the gas cylinder to the specified position, the connecting gear 966 is meshed with the rack 1 43 (the angle will not change when the two are not meshed, which ensures the smoothness of the subsequent meshing of the two), and the gas cylinder valve is clamped into the lower end of the claw head 42. The motor 411 drives the claw head 42 and the rack 1 43 to rotate through the transmission shaft 412. The rotating claw head 42 opens the upper valve of the gas cylinder. At the same time, the rack 1 43 drives the connecting gear 966 to rotate (and because the diameter of the rack 1 43 is larger than the diameter of the connecting gear 966, the gear set is in an accelerated state as a whole. The speed increase setting ensures that when the claw head 42 rotates a small range of angles, the corresponding tube 97 can rotate several circles, so that it can be smoothly threaded with the protruding port). The bevel gear 4 964 that rotates synchronously with the connecting gear 966 Drives bevel gear three 963 to rotate, gear two 962 coaxial with bevel gear three 963 drives gear one 961 to rotate, and gear one 961 drives rack two 952 to rotate, and the rotating column 951 rotating synchronously with rack two 952 drives square tube 94 to rotate, and square tube 94 drives corresponding tube 97 to rotate. Due to the cooperation between the rear end thread inside the corresponding tube 97 and the front end thread of the fixed tube 92, the rotating corresponding tube 97 drives the square tube 94 to move forward (due to the horizontal sliding arrangement between the square tube 94 and the rotating sleeve 95, the square tube 94 can move back and forth, and since annular sliders are provided at the front and rear ends of the rotating column 951, the annular slider is rotatably arranged in the arc track of the connecting frame, so the rotating sleeve 95 can only rotate and cannot move back and forth), and the spirally moving corresponding tube 97 is threadedly connected to the extension port of the gas cylinder.

[0042] Reference Figure 1-2 、 Figure 5 As shown, the jacking module 5 includes a cylinder 51, a jacking rod 52, a buffer plate 53, and a buffer spring 54. The cylinder 51 is installed in the installation groove opened in the base 1, and the protruding end of the cylinder 51 is connected to the jacking rod 52. The jacking rod 52 and the guide sleeve provided at the lower end of the buffer plate 53 are slidably connected, and a buffer spring 54 is connected between the jacking rod 52 and the guide sleeve. The jacking module 5 has the function of buffering the positioning module 8 that falls back and resets and the empty bottle.

[0043] Reference Figure 1 、 Figure 6 As shown, the suspension module 7 includes a suspension hook 71 and a return spring 72. The suspension hook 71 is slidably set in a sliding groove opened at the upper end of the side plate 6. The suspension hook 71 is C-shaped as a whole, and the upper and lower end faces of the suspension hook 71 are provided with inclined surfaces to cooperate with the positioning module 8. A return spring 72 is connected between the suspension hook 71 and the sliding groove, and the return spring 72 plays a role of elastic reset.

[0044] Reference Figure 1 、 Figure 5-6As shown, the gas cylinder is prone to tilting or falling after being placed. To address the above problems, the present application is provided with a positioning module 8, specifically, the positioning module 8 includes a working plate 81, a working groove 82, a clamping member 83, a reset assembly 84, a supporting plate 85, an extrusion column 86, an extrusion plate 87, and a fixing assembly 88. The left and right side walls of the working plate 81 are provided with resistance sliders, the outer sleeve of the resistance slider is provided with a rubber sleeve, and the resistance slider is set up and down in the lifting groove opened in the side plate 6. The resistance slider can control the resistance-increasing movement of the working plate 81. The lower end of the support plate 85 is connected to the work plate 81 by a resetting assembly 84, and an extrusion column 86 is installed in the middle of the lower end of the support plate 85. The extrusion column 86 slides in the extrusion hole opened in the working plate 81, and the lower end of the support plate 85 is engaged with the work plate 81. Extrusion plates 87 are symmetrically installed on the left and right sides. The extrusion plates 87 are squeezed and matched with the inclined surfaces of the upper ends of the suspension hooks 71. A placement groove is provided on the upper end of the support plate 85. The placement groove is rotatably connected to the lower end of the fixing assembly 88. The inner inclined surface of the clamping member 83 is a structure that gradually tilts downward from the outside to the inside, and the inclined surface of the clamping member 83 contacts the rounded structure of the lower end of the extrusion column 86. When the support plate 85 descends under the gravity of the gas cylinder, the distance between the extrusion plate 87 and the clamping member 83 gradually decreases, and the support plate 85 descends to When the distance from the working plate 81 is the smallest, the distance between the extrusion plate 87 and the clamping member 83 is smaller than the distance between the upper and lower ends of the suspension hook 71. When the jacking module 5 drives the positioning module 8 to rise to the specified position as a whole, the clamping member 83 is clamped with the lower end of the suspension hook 71. The extrusion plate 87 is not in contact with the upper inclined surface of the suspension hook 71 at this time. When the gas in the gas cylinder is gradually discharged and the weight of the gas cylinder becomes lighter, the support plate 85 gradually rises under the action of the reset assembly 84, and the extrusion plate 87 that rises synchronously squeezes the upper inclined surface of the suspension hook 71.

[0045] Reference Figure 1-2 、 Figure 5-7 As shown, the fixing assembly 88 includes an angle rod 881 and a clamp 882. The lower end of the angle rod 881 is connected to the side end of the placement slot through a pin shaft, and the angle rod 881 is connected to the placement slot through an extrusion spring. The upper end of the angle rod 881 is installed with a clamp 882. When the clamp 882 is closed, it is in a circular ring shape, and its diameter is the same as the diameter of the gas cylinder.

[0046] At this time, the cylinder 51 drives the lifting rod 52 and the buffer plate 53 to descend, disengage from the positioning module 8 and descend to the initial position (the positioning module 8 does not follow the decline), and then the valve of the gas cylinder is opened. When the gas in the cylinder is completely discharged, the squeezing plate 87 squeezes the hanging hook 71 to the outermost side, and the lower end of the hanging hook 71 is disconnected from the clamping member 83. As the corresponding tube 97 is disconnected from the extension port of the valve, the positioning module 8 as a whole descends in an increased resistance manner under the action of gravity (because the side wall of the working plate 81 is provided with a resistance slider, and the outer sleeve of the resistance slider is provided with a rubber sleeve, the positioning module 8 does not fall directly, but slowly descends due to the friction between the rubber sleeve and the lifting groove, and a buffer spring 54 is connected between the lifting rod 52 and the buffer plate 53, so the positioning module 8 will not be damaged).

[0047] Reference Figure 1 、 Figure 8 As shown, the daily working environment of the bus cannot maintain an absolutely dust-free environment. In order to maintain the sealing of the air pipe to prevent the entry of external gas when the bus is not working, the present application is provided with a connecting module 11. Specifically, the connecting module 11 includes a connecting pipe 111, a built-in spring 112, a blocking plate 113, and a sealing ring 114. The rear end of the connecting pipe 111 is connected to the bus body 12, and the connecting pipe 111 is installed at the front end of the back plate 2. The front end of the connecting pipe 111 is connected to the blocking plate 113 through the built-in spring 112. The blocking plate 113 is slidably arranged inside the connecting pipe 111, and the sealing ring 114 cooperating with the blocking plate 113 is arranged on the inner wall of the connecting pipe 111. The lower end of the blocking plate 113 is a frustum design, and the inclined surface of the lower end of the blocking plate 113 cooperates with the upper end of the sealing ring 114 to block the connecting pipe 111, thereby ensuring the internal sealing effect of the connecting pipe 111 when it is not working. The expanded diameter cavity above the blocking plate 113 is opened inside the connecting pipe 111.

[0048] During the actual working process, the lifting module 5 drives the positioning module 8 to rise, and the conical structure at the upper end of the docking tube 93, which rises synchronously with the positioning module 8, pushes open the blocking plate 113, and then the outer wall of the docking tube 93 is in direct contact with the sealing ring 114. The direct contact between the two improves the sealing degree between the docking tube 93 and the connecting tube 111, preventing external gas from seeping in from the gap between the two. The docking tube 93 continues to rise until the blocking plate 113 is pushed into the expanded cavity. At this time, the gas in the docking tube 93 can be smoothly transported to the bus body 12.

[0049] The implementation principle of this embodiment is:

[0050] Step 1: Place and position: Place the gas cylinder in the placement slot. The gas cylinder presses the angle rod 881 downward. The angle rod 881 rotates and drives the clamp 882 to adjust and fix the body of the gas cylinder. When the fixing assembly 88 fixes the gas cylinder, the support plate 85 descends under the gravity of the gas cylinder. The squeezing column 86 squeezes the clamping member 83 downward. The clamping members 83 arranged on the left and right extend in the opposite direction. Then the cylinder 51 lifts the positioning module 8 as a whole through the lifting rod 52 and the buffer plate 53. When the positioning module 8 rises to the specified height, the clamping member 83 is engaged with the suspension hook 71. Then the buffer plate 53 descends to the initial position (the positioning module 8 will not follow the descent).

[0051] Step 2, docking and communication: the docking pipe 93 that rises synchronously with the positioning module 8 pushes open the blocking plate 113, so that the docking pipe 93 and the connecting pipe 111 are sealed and ventilated, and the connecting gear 966 that rises synchronously engages with the rack 1 43, and the gas cylinder valve enters the inner side of the claw head 42. The motor 411 drives the claw head 42 and the rack 1 43 to rotate synchronously, and the valve of the gas cylinder in the claw head 42 is rotated and opened. At the same time, the rack 1 43 drives the connecting gear 966 to rotate, and the square tube 94 and the corresponding tube 97 are driven to rotate under the cooperation of the bevel gear 4 964, the bevel gear 3 963, the gear 2 962, and the gear 1 961. Under the thread cooperation of the corresponding tube 97 and the fixed tube 92, the corresponding tube 97 rotates and moves forward to the rear end of the protruding port to perform thread-sealed docking. At this time, the gas cylinder and the bus body 12 are connected;

[0052] Step 3: Gas delivery: The gas in the gas cylinder is delivered to the bus body 12 (the valve structures on the bus body 12 are all in the open state, and the opening and closing of the gas inside the bus body 12 are transferred to the connecting module 11 placed in the present application to match the gas cylinder), and the bus body 12 delivers the gas to the designated area;

[0053] Step 4, disconnection: During the gas transmission process, the weight of the gas cylinder gradually decreases, the supporting plate 85 gradually rises, and the extrusion plate 87 contacts the inclined surface of the upper end of the hanging hook 71 to squeeze it outward. After the gas in the gas cylinder is completely output, the hanging hook 71 is squeezed to the outermost side. At this time, the lower end of the hanging hook 71 is decoupled from the clamping part 83. After the corresponding tube 97 is disengaged from the protruding port of the gas cylinder, the positioning module 8 as a whole drops to the initial position under the action of gravity, and then the air cylinder is replaced.

[0054] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
