DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 , Figure 2 As shown, a high-efficiency degassing and sampling device for insulating oil includes a vacuum degasser main body 1, a feed port 2 is arranged on the top of the vacuum degasser main body 1, a guiding and conveying mechanism 3 is arranged on the top of the vacuum degasser main body 1 and outside the feed port 2, a discharge port 4 is arranged at the bottom of the vacuum degasser main body 1, and a plurality of side panels 5 are evenly distributed on the outside of the vacuum degasser main body 1, and a supporting leg 6 is installed at the bottom of each side panel 5.

[0024] like Figures 2 to 5As shown, the guide conveying mechanism 3 includes a first mounting frame 301, the first mounting frame 301 is mounted on the top of the vacuum degassing machine body 1, a conveying cover 302 is movably mounted inside the first mounting frame 301, a limiting block 3021 is arranged on the outer surface of the conveying cover 302, a limiting groove 3011 is arranged inside the first mounting frame 301, the limiting block 3021 is movably arranged inside the limiting groove 3011, a conveying auger 303 is fixedly mounted on the inner wall of the conveying cover 302, a plurality of through holes 3031 are arranged on the surface of the conveying auger 303, and a bottom of the conveying auger 303 is provided with a plurality of through holes 3031. A conveying pipe 304 is provided at the bottom, and the bottom of the conveying pipe 304 is set inside the feed port 2. A second mounting bracket 306 is installed on one side of the upper surface of the first mounting bracket 301, and a driving motor 307 is installed on the top of the second mounting bracket 306. A rotating rod 308 is installed at the output end of the driving motor 307. One end of the rotating rod 308 is rotatably set on the upper surface of the first mounting bracket 301, and a transmission gear 309 is fixedly installed on the rod body of the rotating rod 308. A gear ring 305 is fixedly installed on the outer surface of the conveying cover 302, and the transmission gear 309 and the gear ring 305 are meshed with each other.

[0025] Through the meshing transmission between the transmission gear 309 and the gear ring 305, under the drive of the driving motor 307, the entire conveying cover 302 can be controlled to rotate, thereby driving the internal conveying auger 303 to rotate, which not only plays a role in conveying the insulating oil, but also can break up the volume of the insulating oil, making the conveying speed of the insulating oil faster.

[0026] The working principle of this high-efficiency degassing and sampling device for insulating oil:

[0027] When in use, the discharge port 4 of the vacuum degasser main body 1 is connected to the detection instrument, and the insulating oil is conveyed by guiding the conveying mechanism 3, so that the insulating oil enters the interior of the vacuum degasser main body 1 through the feed port 2. The insulating oil is degassed through the operation of the vacuum degasser main body 1, and then conveyed from the discharge port 4 to the interior of the detection instrument for detection and processing. When conveying the insulating oil, pour the insulating oil above the conveying cover 302, and the rotating rod 308 can be driven to rotate by the driving motor 307. Under the meshing action between the transmission gear 309 and the gear ring 305, the entire conveying can be driven. The cover 302 rotates, so that the conveying auger 303 inside the conveying cover 302 can rotate along with it. The rotation of the conveying auger 303 can convey the insulating oil and disperse the overall volume of the insulating oil, so that the insulating oil can be conveyed from the feed port 2 to the inside of the vacuum degasser body 1 more quickly. A through hole 3031 is provided on the surface of the conveying auger 303, so that the insulating oil can also fall to the bottom through the through hole 3031. The conveying of the insulating oil by the rotation of the conveying auger 303 can effectively reduce the accumulation of the insulating oil and increase the conveying speed of the insulating oil at the feed port 2, thereby making the injection rate higher.
