[0039] The oil drain valve separation assembly further includes a first telescopic driving member 5 , which is mounted on the first mounting plate 4 , and a first micro motor 6 is mounted on the telescopic end of the first telescopic driving member 5 .

[0040] The oil drain valve clamping assembly includes a mounting column 7 and a second telescopic drive member 8. The mounting column 7 is mounted on the output shaft of the first micro motor 6. Two second telescopic drive members 8 are provided. The two second telescopic drive members 8 are symmetrically mounted on the upper and lower sides of the outer surface of the mounting column 7 through a bracket. The two second telescopic drive members 8 are located on the outer surface of the mounting column 7 at one end away from the first micro motor 6.

An oil drain valve clip 9 is fixed to the telescopic end of each second telescopic drive member 8, and the two oil drain valve clips 9 are symmetrically arranged up and down.

[0041] The plug separation assembly includes a third telescopic drive member 10, a fourth telescopic drive member 11 and a clamping block 12. Two third telescopic drive members 10 are provided, and the two third telescopic drive members 10 are symmetrically installed on the first mounting plate 4. Two fourth telescopic drive members 11 are provided, and the two fourth telescopic drive members 11 are respectively installed on the telescopic ends of the two third telescopic drive members 10. Two clamping blocks 12 are provided, and the two clamping blocks 12 are symmetrically installed on the telescopic ends of the two fourth telescopic drive members 11. The two clamping blocks 12 are symmetrically arranged.

[0042] The clamping block 12 is provided with an arc-shaped groove for clamping the rubber plug.

[0043] The lifting assembly is two first lifting drive members 3, and the first mounting plate 4 is installed on the lifting ends of the two first lifting drive members 3; the bottom of the container 13 is installed on the inner bottom of the chassis 1 through a lifting platform.

[0044] In this embodiment, when the oil extraction robot is used, the robot body moves to the oil extraction position of the transformer to be extracted oil through the moving crawler 2, and then the first lifting drive member 3 drives the oil drain valve clip 9 to move downward, so that the oil drain valve clip 9 moves downward to the oil drain valve position of the transformer, and then the first telescopic drive member 5 extends, driving the upper and lower oil drain valve clips 9 to move to the upper and lower sides of the oil drain valve, and then the two second telescopic drive members 8 extend to drive the two oil drain valve clips 9 close to each other, clamping the oil drain valve, the first micromotor 6 drives the mounting column 7 to rotate, and then the mounting column 7 drives the two oil drain valve clips 9 to rotate, driving the clamped oil drain valve to rotate, and then the oil drain valve is opened, and then the first telescopic drive member 5 contracts, driving the two oil drain valve clips 9 to move away from the transformer, and then the oil drain valve is loosened and removed.

[0046] The robot realizes the automatic opening of the oil drain valve during the oil extraction process of the transformer, and automatically removes the rubber plug after the oil drain valve is opened, realizing the automatic opening of the transformer oil drain valve to extract oil. The robot can automatically drive to the oil extraction position of the transformer and automatically open the oil drain valve to extract oil, eliminating the manual oil extraction operation and improving the oil extraction efficiency.

[0047] Example 2

[0048] Combine Figure 1-12 As shown, the difference between this embodiment and embodiment 1 is that an adjustable drainage component is provided on the containing barrel 13, a clamping component is installed in the containing barrel 13, and the adjustable drainage component is located above the clamping component.

[0049] The clamping assembly includes a second micro motor 14, a fifth telescopic drive member 15 and an arc clamp 16. Two second micro motors 14 are provided, and the two second micro motors 14 are symmetrically installed on the side wall of the filling barrel 13. Two fifth telescopic drive members 15 are provided, and the two fifth telescopic drive members 15 are respectively installed on the output shafts of the two second micro motors 14. Two arc clamps 16 are provided, and the two arc clamps 16 are symmetrically installed on the telescopic ends of the two fifth telescopic drive members 15.

[0050] The adjustable drainage assembly includes a first mounting frame 17, an expanded channel plate 18, a first side plate 19, a lower channel plate 20 and a second side plate 21. Two first mounting frames 17 are provided, and the two first mounting frames 17 are symmetrically fixed to the outer wall of the filling barrel 13. The two first side plates 19 are respectively fixed to the two first mounting frames 17. The expanded channel plate 18 is fixed between the two first side plates 19. The spacing between the first side plates 19 gradually increases from bottom to top. The lower channel plate 20 is fixed to the bottom of the expanded channel plate 18. Two second side plates 21 are symmetrically fixed on both sides of the lower channel plate 20. A plurality of guide grooves 22 are opened on the upper surface of the lower channel plate 20. The spacing between the plurality of guide grooves 22 gradually decreases from bottom to top and diverges from top to bottom.

[0051] In this embodiment, before taking oil, the oil sample bottle is first clamped between the two arc clamps 16, and the fifth telescopic drive member 15 is extended to drive the two arc clamps 16 to approach each other to clamp the oil sample bottle. Then, after the robot removes the rubber plug, the first lifting drive member 3 drives the oil drain valve clip 9 and the clamping block 12 to move upward, thereby the clamping block 12 moves upward from the window position on the front side of the chassis, and then the containing barrel 13 moves upward, so that the flared channel plate 18 moves to the window position of the chassis 1, and then the oil sprayed from the oil drain pipe is sprayed to the position of the flared channel plate 18.

[0052] Before the oil sample bottle is filled with oil sample, it needs to be cleaned inside and outside with oil. The oil is sprayed onto the flared channel plate 18 and flows downward, then flows into the guide groove 22, and then the oil is dispersed. After the oil is dispersed, it drips down from the bottom end of the lower channel plate 20. After the oil is dispersed and drips down, it flows to the oil sample bottle below the bottom end of the lower channel plate 20 in a dispersed state.

[0053] The oil is dispersed by the guide groove 22 so that the oil will not gather together and flow down, ensuring that the width of the dispersed oil is larger than the size of the oil sample bottle itself, so that the oil sample bottle is covered. At this time, the second micro motor 14 drives the fifth telescopic drive member 15 and the arc clamp 16 to rotate, which can drive the oil sample bottle to rotate. During the rotation, the oil flowing down from above can clean the outer and inner surfaces of the oil sample bottle, thereby realizing automatic cleaning of the oil sample bottle before the oil sample is placed.

[0054] Example 3

[0055] Combine Figure 1-12As shown, the difference between this embodiment and embodiment 2 is that the adjustable drainage assembly also includes a flow gathering assembly, which includes a sixth telescopic driving member 23, a triangular plate 24, a connecting rod 25, a sliding box 26, a torsion spring shaft 27, a connecting rod 28 and a merging plate 29. Two sixth telescopic driving members 23 are arranged on the lower surface of the lower channel plate 20. The telescopic ends of the two sixth telescopic driving members 23 are connected to the triangular plate 24. The triangular plate 24 is slidably connected to the lower surface of the lower channel plate 20. Two connecting rods 25 are fixed on both sides of the triangular plate 24. The outer sides of the two second side plates 21 are both provided with sliding grooves 30. The two sliding boxes 26 slide in the two sliding grooves 30 respectively. The upper ends of the two connecting rods 25 are respectively connected to the two sliding boxes 26. The two torsion spring shafts 27 are respectively installed on the bottom of the two sliding boxes 26. There are two merging plates 29. The bottom end of each torsion spring shaft 27 is connected to the two merging plates 29 through two connecting rods 28.

[0056] In this embodiment, after the oil sample bottle is cleaned, it is necessary to fill the oil sample bottle with oil. However, the diameter of the bottle mouth of the oil sample bottle is small. In order to allow the oil flowing downward from the lower channel plate 20 to quickly converge downward so that it can flow directly into the oil sample bottle, the sixth telescopic drive member 23 extends to drive the triangular plate 24 to slide at the bottom of the lower channel plate 20. At the same time, the triangular plate 24 drives the connecting rod 25 to move, and then the connecting rod 25 drives the sliding box 26, the torsion spring shaft 27, the connecting rod 28, and the merging plate 29 to move.

[0057] When the two merging plates 29 are located on both sides of the second side plate 21, the spring in the torsion spring shaft 27 is in a force-storing and contracted state. When the sliding box 26 moves to the end position of the slide groove 30, the inner side of the merging plate 29 loses the support of the second side plate 21 and is subjected to the elastic force of the torsion spring shaft 27. Then, the two merging plates 29 are merged into the two triangular sides of the triangular plate 24, so that the triangular plate 24 and the two merging plates 29 form a closed triangular channel plate, and then the oil flowing out from the bottom of the lower channel plate 20 will enter the triangular channel plate, and then converge to the tip outlet of the triangular channel plate. The tip outlet is located above the bottle mouth of the oil sample bottle, and then the oil sample is stored in the oil sample bottle, completing the oil sample bottling.

[0058] During the processing, the oil sample is first dispersed to expand its flow width coverage area, and the oil sample bottle is fully covered and automatically cleaned. After cleaning, the oil sample is gathered and automatically bottled.

[0059] This realizes the fully automated operation of transformer oil extraction.

They are only used to illustrate the technical ideas and features of the present invention. Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. However, they are not limited to the present invention alone, and the patent scope of the present invention cannot be limited solely by these embodiments. That is, any equivalent changes or modifications made to the spirit disclosed by the present invention, for researchers or technicians in this field, without departing from the structure of the present invention, local improvements within the system and changes and conversions between subsystems, etc., are still within the patent scope of the present invention.
