[0030] The filling mechanism 2 includes an air inlet pipe 21 and a filling main pipe 22. The air inlet pipe 21 is fixedly mounted on the side wall of the filling station body 1. The air outlet end of the air inlet pipe 21 is connected to the filling main pipe 22. The air outlet end of the filling main pipe 22 is connected to a plurality of filling branch pipes 23. Each of the filling branch pipes 23 can be connected to and communicated with the corresponding gas cylinder 4 to be filled.

[0031] The cooling mechanism 3 includes a lifting assembly 31, which is fixedly mounted on the inner bottom wall of the filling station body 1. A plurality of annular tubes 32 are mounted on the lifting end of the lifting assembly 31. Each of the annular tubes 32 is movably sleeved on the outside of the corresponding gas cylinder 4. A plurality of nozzles 33 are arranged in an annular array on the inner side wall of the annular tube 32. The annular tubes 32 are all connected to a water pipe. The lifting assembly 31 is used to drive the plurality of annular tubes 32 to move up and down along the axis of the gas cylinder 4.

[0032] During the filling process of the gas cylinder, the filling platform drives several annular tubes 32 to move up and down along the axis of the gas cylinder 4 through the lifting component 31, so that the nozzle 33 can evenly spray the coolant on the outer wall of the gas cylinder, thereby cooling the gas cylinder during the filling process to prevent the gas cylinder from being overheated and easily causing an explosion.

[0033] like Figure 2 As shown, the lifting assembly 31 includes a fixing seat 311, a threaded rod 312 and a bracket 314;

[0034] The fixing seat 311 is fixedly installed on the inner bottom wall of the filling station body 1. A groove is provided on one side of the fixing seat 311.

One end of the slider 313 passes through the groove and extends to the outside to be fixedly connected to the bracket 314. Several of the annular tubes 32 are fixedly connected to the bracket 314.

[0035] Specifically, the threaded rod 312 is driven to rotate by a servo motor, and the slider 313 is driven to slide along the groove during the rotation of the threaded rod 312. The slider 313 drives the several annular tubes 32 connected to the bracket 314 to move up and down during the sliding process, so that the several nozzles 33 in each annular tube 32 evenly spray the coolant on the outer surface of the gas cylinder 4, thereby reducing the temperature of the gas cylinder 4 when filling, and avoiding the gas cylinder 4 from being overheated during filling and easily causing an explosion.

[0036] It is worth noting that when installing the gas cylinder 4, the annular tube 32 is located at the filling branch pipe 23. After the gas cylinder 4 is docked with the filling branch pipe 23, the annular tube 32 is driven down so that the annular tube 32 is sleeved on the outside of the gas cylinder 4 to avoid interference with the installation and disassembly of the gas cylinder 4.

The set liquid level sensor can monitor the liquid level height in the liquid collecting tank 11 to prevent the coolant from overflowing from the liquid collecting tank 11 and flowing into the interior of the filling station body 1 to pollute the working environment inside the filling station body 1.

[0041] like Figure 1 As shown, a plurality of infrared thermometers are installed on the inner side wall of the filling station body 1, and the plurality of infrared thermometers are respectively set corresponding to the gas cylinders 4.

[0042] Specifically, the infrared thermometer can monitor the temperature of each gas cylinder during filling in real time to avoid the temperature of the gas cylinder being too high during filling, which may easily cause an explosion.

[0044] Specifically, the camera 5 can replace manual labor to monitor the internal situation of the filling station body 1 in real time, ensure the safety of the staff, and promptly know the operating status of the equipment and the filling status of the gas cylinders in the filling station body 1. The temperature sensor 6 can detect the temperature in the filling station body 1 in real time to avoid the temperature in the filling station body 1 being too high and affecting the filling of the gas cylinders 4.

[0045] like Figure 1 As shown, a display screen 7 and an alarm 8 are installed on the outer side wall of the filling station body 1 , and the alarm 8 is located above the display screen 7 .

[0046] Specifically, the display screen 7 can display the temperature inside the filling station body 1 and the filling status of the gas cylinder 4 in real time, which is convenient for relevant personnel to understand, and an alarm can be issued through the alarm 8, avoiding the failure to promptly warn relevant personnel when an unexpected situation occurs inside the filling station body 1.

[0047] like Figure 1 As shown, an exhaust pipe 9 is provided in the filling station body 1 , one end of the exhaust pipe 9 extends to the outside of the filling station body 1 , a fan 91 is fixedly installed in the exhaust pipe 9 , and filters 92 are fixedly installed at both ends of the exhaust pipe 9 .

[0048] Specifically, through the cooperation of the exhaust pipe 9, the fan 91 and the filter 92, the interior of the filling station body 1 can be ventilated through the fan 91, thereby avoiding the internal temperature of the filling station body 1 being too high and the compressed gas being too concentrated.

[0049] like Figure 1 As shown, a stop valve 24 is installed on the filling main pipe 22, and a pressure gauge 25 and a solenoid valve are installed on each of the filling branch pipes 23.

[0050] Specifically, the pressure gauge 25 provided can monitor the pressure of the gas cylinder 4 during filling in real time to avoid explosion caused by excessive pressure in the gas cylinder 4, and the solenoid valve provided can conveniently control the connection status between the filling branch pipe 23 and the gas cylinder 4.
