[0049] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0050] As Figures 1 to 4 shown, this embodiment proposes an SF6 comprehensive on-line monitoring device, including a monitor body 1, and also including: a bottom plate 2, a box body 3, a processing mechanism and a lifting mechanism. A plurality of moving wheels 24 are arranged on the bottom plate 2. Two slide rods 22 are fixedly connected inside the box body 3. Two slide blocks 23 are fixedly connected to the drying box 4. Slide holes are opened on the two slide blocks 23. The two slide rods 22 are respectively slidably arranged in the two slide holes. The box body 3 is arranged on the bottom plate 2, and the monitor body 1 is arranged on the box body 3. Through the cooperation among the bottom plate 2, the box body 3, the processing mechanism and the lifting mechanism, when the micro water content in the SF6 gas in the compartment is too high, it is convenient for the staff to immediately process the position in the SF6 gas at the same time, improving the processing efficiency of the micro water and reducing the possibility of power failure.

[0051] As Figures 1 to 4As shown in the figure, a processing mechanism is arranged in the box body 3 for processing the moisture in SF6. The processing mechanism includes: a drying box 4, an air inlet pipe 5, a weighing assembly, a conveying assembly, and an air outlet assembly. The drying box 4 is slidably arranged in the box body 3. An air inlet hole is opened on the drying box 4. The air inlet pipe 5 is arranged on the box body 3. The bottom end of the air inlet pipe 5 contacts the drying box 4 and communicates with the air inlet hole. The monitor body 1 is arranged in the air inlet pipe 5. The weighing assembly is arranged in the box body 3 for weighing the drying box 4. The conveying assembly is arranged in the air inlet pipe 5 for conveying SF6 gas. The air outlet assembly is arranged on the drying box 4 for outputting the processed SF6 gas. The weighing assembly includes: an iron block 6, an electromagnet 7, a first electric cylinder 8, and a weighing scale 9. The iron block 6 is fixedly connected to the drying box 4. The electromagnet 7 is arranged in the box body 3. The first electric cylinder 8 is arranged on the box body 3. The output end of the first electric cylinder 8 is fixedly connected to the electromagnet 7. The weighing scale 9 is arranged in the box body 3. The drying box 4 is arranged on the top of the weighing scale 9. The conveying assembly includes: a conveying box 10 and a fan 11. The conveying box 10 is communicated with the air inlet pipe 5. The fan 11 is arranged in the conveying box 10. The air outlet assembly includes: an air outlet pipe 12 and a connection box 13. The air outlet pipe 12 is communicated with the drying box 4. The connection box 13 is communicated with the air outlet pipe 12. Specifically, when the monitor body 1 monitors that the moisture in the SF6 gas is too high, the fan 11 in the conveying box 10 extracts the SF6 gas in the compartment and conveys it into the drying box 4 through the air inlet pipe 5. The moisture is absorbed by the desiccant in the drying box 4. The SF6 gas after the moisture is absorbed is conveyed back into the compartment through the air outlet pipe 12 and the connection box 13, thereby reducing the moisture content in the SF6 gas. When it is necessary to know the moisture content, the suction force of the electromagnet 7 on the iron block 6 is released, so that the drying box 4 falls on the weighing scale 9 for weighing, and then the moisture content can be known. After weighing, the first electric cylinder 8 descends to make the electromagnet 7 suck the iron block 6, so that the drying box 4 is reset.

[0052] As Figures 1 to 3As shown in the figure, a lifting mechanism is arranged on the bottom plate 2 to adjust the height of the box body 3. The lifting mechanism includes: a sliding cylinder 14, a lifting rod 15, a driving component and a fixing component. The sliding cylinder 14 is fixedly connected to the bottom plate 2. The lifting rod 15 is slidably arranged in the sliding cylinder 14. The box body 3 is fixedly connected to the lifting rod 15. The driving component is arranged on the sliding cylinder 14 and is used to drive the lifting rod 15 to move up and down. The fixing component is arranged on the sliding cylinder 14 and is used to fix the lifting rod 15. The driving component includes: a toothed belt 16, a driving gear 17 and a first motor 18. The toothed belt 16 is fixedly connected to the lifting rod 15. The driving gear 17 is rotatably arranged on the sliding cylinder 14. The driving gear 17 meshes with the toothed belt 16. The first motor 18 is arranged on the sliding cylinder 14. The output end of the first motor 18 is fixedly connected to the driving gear 17. The fixing component includes: a fixing frame 19, a fixing block 20 and a second electric cylinder 21. The fixing frame 19 is fixedly connected to the sliding cylinder 14. The fixing block 20 is arranged in the fixing frame 19. The fixing block 20 contacts the lifting rod 15. The second electric cylinder 21 is arranged on the fixing frame 19. The output end of the second electric cylinder 21 is fixedly connected to the fixing block 20. Specifically, the first motor 18 arranged on the sliding cylinder 14 drives the driving gear 17 to rotate on the toothed belt 16, thereby driving the lifting rod 15 to adjust the height. And the second electric cylinder 21 arranged on the fixing frame 19 drives the fixing block 20 to abut against the lifting rod 15, thereby fixing the lifting rod 15, and further supporting the box body 3 to adapt to the height of the compartment.

[0053] In this embodiment, when the micro water content in the SF6 gas is detected to be too high, the first motor 18 arranged on the sliding cylinder 14 drives the driving gear 17 to rotate on the toothed belt 16, thereby driving the lifting rod 15 to adjust the height. And the second electric cylinder 21 arranged on the fixing frame 19 drives the fixing block 20 to abut against the lifting rod 15, thereby fixing the lifting rod 15, and further supporting the box body 3 to adapt to the height of the compartment. When the monitor body 1 detects that the micro water in the SF6 gas is too high, the blower 11 in the delivery box 10 extracts the SF6 gas in the compartment and transports it into the drying box 4 through the intake pipe 5. The desiccant in the drying box 4 absorbs the moisture. After the moisture is absorbed, the SF6 gas is transported back into the compartment through the outlet pipe 12 and the connection box 13, thereby reducing the micro water content in the SF6 gas. When it is necessary to know the micro water content, the electromagnet 7 releases the suction force on the iron block 6, so that the drying box 4 falls on the weighing scale 9 for weighing, and then the micro water content can be known. After weighing, the first electric cylinder 8 descends, and the electromagnet 7 sucks the iron block 6, so that the drying box 4 returns to its original position.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
