[0041] In this embodiment, as shown in the accompanying drawings Figure 11 As shown, the supplementary assembly comprises a helium storage bottle 40 installed on one side of the circulating pipe 12; the helium storage bottle 40 is fixedly connected between the cabinet body 1, the top end of the helium storage bottle 40 is fixedly communicated with a booster pump 41, the output end of the booster pump 41 is threadedly communicated with a conveying hose 42, the top end of the conveying hose 42 is fixedly installed with a top valve 43, and the top valve 43 is fixedly communicated between the sleeve sealing plate 31; one side of the outer wall of the conveying hose 42 is fixedly communicated with a connecting hose 44, one end of the connecting hose 44 is installed with a peripheral valve 45, and the sleeve plate 7 and the connecting hose 44 are both fixedly communicated with the peripheral valve 45. The helium storage bottle 40 is made of stainless steel material, and the helium storage bottle 40 is used for storing helium.
[0042] The use process of the environment-friendly outdoor ring main unit is as follows:
[0043] Step one, when the connection is in use, the outdoor cover 16 is placed outdoors, and the outdoor cover 16 can prevent dust and rain on the multiple cabinet bodies 1, and the pressure transmitter 19 is rotated, the pressure transmitter 19 is threadedly separated from the detection tube 18, that is, the detection tube 18 is filled with helium, the helium enters the space formed between the inflatable sleeve plate 17 and the environmental protection gas tank 2 through the detection tube 18, thereby forming an inflatable protection operation between the environmental protection gas tank 2 and the inflatable sleeve plate 17. After filling with helium, the pressure transmitter 19 is locked with the detection tube 18, the connection operation is completed, and the helium is a gas with good environmental protection performance and is more difficult to pollute the environment. Then connect the connection line head 25 to the power line bundle, and connect the bottom of the contact terminal 21 to the device connection line bundle, so that the controller 20 drives the switching motor 24 to rotate the rotating shaft 23, and the rotating shaft 23 can drive multiple power-off terminals 22 to rotate downward, and the power-off terminals 22 are connected with the contact terminals 21 to close the circuit, thereby forming a power supply path.
[0044] At the same time, the pressure transmitter 19 detects the gas pressure in the detection tube 18, and since the detection tube 18 is in communication with the inflatable sleeve plate 17, the pressure transmitter 19 can detect the helium pressure between the inflatable sleeve plate 17 and the environmental protection gas tank 2. When the helium pressure detected by the pressure transmitter 19 is lower than the pressure value set by the controller 20, it is known that there is a problem of leaking helium at the environmental protection gas tank 2, and the driving motor 5 can be started immediately by the controller 20.
[0045] Step two, when the periphery is detected and blocked, the driving motor 5 drives the screw rod 4 to rotate, and the sleeve block 6 carried by the screw rod 4 moves upward under the action of the threaded transmission force. The sleeve block 6 moves upward along the inner wall of the sleeve frame 3, and the sleeve block 6 drives the sleeve plate 7 to move upward, and the sleeve plate 7 drives the two blocking air bags 8 to move upward. Two blocking air bags 8 move upward along the outer wall of the environmental protection gas tank 2. At the same time, the controller 20 starts the circulating fan 10, and the connecting pipe 9 can generate suction force, and the connecting pipe 9 can suck the air in the gap surrounded by the sleeve plate 7 and the two blocking air bags 8, and the air enters the first helium detector 11 after being pressurized by the circulating fan 10, and then is transported to the position behind the sleeve plate 7 through the circulating pipe 12, and continues to enter the gap surrounded by the sleeve plate 7 and the two blocking air bags 8. In this way, during the upward movement of the sleeve plate 7, the helium gas leakage position of the environmental protection gas tank 2 is quickly detected, and when the first helium detector 11 detects helium, it is known that the gap surrounded by the sleeve plate 7 and the two blocking air bags 8 has a helium leakage position.
[0046] The controller 20 immediately turns off the drive motor 5. At this point, the two sealing airbags 8 and the sleeve rectangular plate 7 are positioned at the helium leak site outside the environmental gas cabinet 2. The controller 20 then immediately opens the air inlet valve 14 and starts the inflation pump 13. The inflation pump 13 causes the air inlet valve 14 to pressurize the outside air and allow it to enter the boost pipe 15. The air then enters the two sealing airbags 8 through the boost pipe 15. After the two sealing airbags 8 are pressurized and expanded, they are squeezed and sealed against the outer wall of the environmental gas cabinet 2. In this way, the two sealing airbags 8 and the sleeve rectangular plate 7 can automatically and completely seal the helium leak site in a timely manner. The controller 20 then closes the air inlet valve 14 and the boost pipe 15 to prevent continued helium leakage. The distance sensor 26 senses the distance to the sleeve block 6, and the distance value sensed by the distance sensor 26 is displayed on the controller 20.
[0047] Step 3: When checking for blockage at the top, controller 20 activates drive motor 29, which drives drive screw 28 to rotate. Drive screw 28 rotates within support frame 27, while sleeve frame 3 supports support frame 27, increasing its stability. Drive screw 28, carrying threaded block 30, moves leftward under the force of the threaded block. Threaded block 30 moves leftward along the inner wall of support frame 27, driving sleeve sealing plate 31 leftward. Sleeve sealing plate 31 then drives rectangular airbag 32 leftward. Rectangular airbag 32, adhering to the top surfaces of multiple environmental protection gas cabinets 2, moves leftward. At the same time, the controller 20 starts the detection fan 34, and the detection fan 34 generates suction in the suction pipe 33. The suction pipe 33 can then suck in the air in the space surrounded by the rectangular air bag 32 and the sleeve sealing plate 31. The air enters the detection fan 34 along the suction pipe 33, and the air enters the second helium detector 35 along the detection fan 34 for detection. After passing through the second helium detector 35, the air enters the guide pipe 36, and continues to circulate through the guide pipe 36 to the space surrounded by the rectangular air bag 32 and the sleeve sealing plate 31.
[0048] When the second helium detector 35 detects helium, the controller 20 shuts off the drive motor 29, stopping the rectangular airbag 32 and the sleeve seal 31. These airbags 32 and sleeve seal 31 are positioned at the helium leak site at the top of the environmental protection gas cabinet 2. Simultaneously, the controller 20 activates the booster pump 38 and opens the intake valve 39. External pressurized air enters the delivery pipe 37 and then enters the rectangular airbag 32. The rectangular airbag 32 then expands and presses against the tops of the multiple environmental protection gas cabinets 2. This completes the seal 31 and rectangular airbag 32 sealing the tops of the environmental protection gas cabinets 2. The controller 20 then shuts off the intake valve 39 and booster pump 38, preventing continued helium leakage from the tops of the environmental protection gas cabinets 2.
[0049] Step four, when the helium gas is replenished, the controller 20 starts to open the top valve 43, and the controller 20 opens the peripheral valve 45, and the controller 20 starts to start the booster pump 41, the booster pump 41 makes the helium gas in the helium storage bottle 40 pressurized into the conveying hose 42, the pressurized helium gas enters into the top valve 43 along the conveying hose 42, because the top valve 43 is in fixed communication with the sleeve sealing plate 31, therefore the pressurized helium gas can enter into the gap surrounded by the sleeve sealing plate 31 and the rectangular air bag 32, and the helium gas leakage position at the top of the environmental protection gas tank 2 is replenished with helium gas, the helium gas can be replenished into the gap surrounded by the environmental protection gas tank 2 and the inflatable sleeve plate 17, and the sealing protection is continued. At the same time, the replenished helium gas in the conveying hose 42 can also enter into the connecting hose 44, enter into the peripheral valve 45 through the connecting hose 44, enter into the gap surrounded by the sleeve plate 7 and the two sealing air bags 8 through the peripheral valve 45, and the helium gas can replenish the peripheral helium gas leakage position of the environmental protection gas tank 2. After the replenishment, when the pressure value of the pressure transmitter 19 is the pressure value set by the controller 20, the controller 20 immediately closes the top valve 43 and closes the peripheral valve 45, and the automatic helium gas replenishment is completed, and the internal environmental protection gas tank 2 can be safely used for closing. The above leakage positions can be quickly repaired by professional personnel when the equipment is shut down for maintenance.
