[0030] The pressure regulating assembly 2 comprises a main pipe 201, an air outlet pipe 202 and an air inlet pipe 203, the upper end of the device body 1 is fixedly installed with the main pipe 201, the two ends of the main pipe 201 extend out of the device body 1, facilitating the filling and discharging of the storage bottle 5; the two ends of the main pipe 201 are fixedly installed with main valves 205 respectively; the main pipe 201 is communicated with at least one set of the air outlet pipe 202 and the air inlet pipe 203, one air outlet pipe 202 and one air inlet pipe 203 form a set, the number of the set is consistent with the number of the storage bottles 5; the lower ends of each set of the air outlet pipe 202 and the air inlet pipe 203 are communicated together and are sealingly and fixedly connected to the bottle opening of the storage bottle 5; each air outlet pipe 202 and air inlet pipe 203 is fixedly installed with a branch valve 204, the branch valve 204 is a check valve, the direction of the branch valve 204 on the air outlet pipe 202 is downward inlet and upward outlet, so that the SF6 gas in the storage bottle 5 can be discharged; the direction of the branch valve 204 on the air inlet pipe 203 is upward inlet and downward outlet, so that the SF6 gas can flow into the storage bottle 5.

[0031] The inside of the device body 1 is fixedly installed with positioning rings 4, the positioning rings 4 are annular structures, the number of the positioning rings 4 is consistent with the number of the storage bottles 5; a stick-shaped structure is arranged between adjacent two positioning rings 4 and between the positioning ring 4 and the inner wall of the device body 1, so as to fix the positioning ring 4; the front of the device body 1 is hingedly installed with a cabinet door 8, the cabinet door 8 is fixedly installed with a first handle 9, facilitating the opening of the cabinet door 8 and the maintenance of the device; the bottom end of the device body 1 is installed with pulleys 6; the back of the device body 1 is fixedly installed with a second handle 10, facilitating the transportation of the device. Preferably, the pulleys 6 are four, and the positioning rings 4 are made of plastic material.

[0032] Each storage bottle 5 is fixedly installed with an air pressure sensor 3 for monitoring the air pressure in the storage bottle 5; the upper end of the side of the device body 1 is fixedly installed with a control module 11, the control module 11 comprises a PLC 12 and an alarm module 13, the PLC 12 is connected with the alarm module 13, and the PLC 12 is connected with the air pressure sensor 3; the alarm module 13 is connected with a mobile terminal 14; the upper end of the front of the device body 1 is fixedly installed with a display screen 7, which can display the air pressure in each storage bottle 5, and the display screen 7 is connected with the PLC 12.

[0033] The working principle of the application is that SF6 gas is input at one end of the main pipe 201 of the device, and the main valve 205 at the end is opened. Since the branch valve 204 is a check valve, it is an automatic valve, so the input SF6 gas naturally enters the storage bottle 5 along the gas inlet pipe 203. After the input of SF6 gas is completed, the main valve 205 at the end is closed, the device is moved to the electrical equipment where SF6 gas is needed, the flange at one end of the main pipe 201 is connected to the electrical equipment, the main valve 205 at the end is opened, and the SF6 gas stored in the device can be used. When the gas pressure of one of the storage bottles 5 is too high, the SF6 gas in the bottle can flow out of the storage bottle 5 along the gas outlet pipe 202 and enter other storage bottles 5 with relatively low gas pressure, thereby achieving the purpose of automatically adjusting the gas pressure in the storage bottles 5.

[0034] The gas pressure sensor 3 monitors the gas pressure in the storage bottle 5 in real time and transmits the gas pressure data to the PLC 12. The PLC 12 processes the data and sends a signal to the alarm module 13 when the gas pressure data exceeds the preset value. The alarm module 13 sends the signal to the mobile terminal 14 carried by the worker to alarm and remind the worker. The PLC 12 also sends the received gas pressure data to the display screen 7, so that the worker can see the gas pressure data in each storage bottle 5 on the display screen 7 and appropriately process the SF6 gas in the device before maintenance to avoid injury to the maintenance personnel caused by high gas pressure.
