[0024] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] like Figures 1 to 3 As shown, an oil-immersed power transformer oil filling device of the utility model comprises a slide 1 capable of moving along the X-axis, the slide 1 is provided with a moving plate 2 capable of moving along the Z-axis, and the moving plate 2 is provided with an oil gun 3 capable of moving along the Y-axis;

[0026] In this embodiment, the oil-immersed power transformers are arranged one by one when they are discharged in order to reduce the floor space. The present application utilizes this arrangement feature and arranges the device on the side of the oil-immersed power transformer to be filled with oil. When in use, the oil-immersed power transformers to be filled with oil are arranged one by one. Since the oil gun 3 can be moved along the XYZ axis, the operator can control the oil gun 3 to automatically insert its oil outlet into the oil filling port of the oil-immersed power transformer for oil filling. Compared with the prior art, the user does not need to hold the oil gun 3 for oil filling, which greatly improves the oil filling efficiency.

[0027] Furthermore, the movable plate 2 is fixedly connected to a cylinder 4, the output end of the cylinder 4 is a lifting plate 5, and the oil gun 3 is fixedly connected to the lifting plate 5;

[0028] The lifting plate 5 is fixedly connected to the cylinder 2 6, and the output end of the cylinder 2 6 is fixedly connected to a lever 7, and the lever 7 is against the switch 8 of the oil gun 3;

[0029] In this embodiment, if Figure 2 and Figure 3 As shown, by controlling the cylinder 1 4, the height of the lifting plate 5 and the oil gun 3 can be controlled, so that the oil gun 3 moves along the Y axis, as shown in FIG. Figure 2 and Figure 3As shown, the lever 7 passes through the oil gun 3, and the lever 7 is against the switch 8 of the oil gun 3. The lever 7 can be controlled to move by controlling the cylinder 2 6. When the oil gun 3 is inserted into the oil filling port, the cylinder 2 6 is operated to make the lever 7 press the switch 8 to move, and the oil gun 3 is filled with oil. After the oil filling is completed, the cylinder 2 6 is operated to make the lever 7 return to the initial position, and the switch 8 closes the oil gun 3 under the action of elastic force.

[0030] Furthermore, the bottom of the slide 1 is a slider 9, which is slidably mounted on a guide rail 10, and a motor 11 is fixedly connected to the slide 1, and the output end of the motor 11 is a gear;

[0031] The guide rail 10 is fixed on the bracket 12. Both sides of the bottom of the bracket 12 are connected to the fixing frame 13. The bottom end of the fixing frame 13 is installed with a plurality of universal wheels 14. The bracket 12 is fixedly connected with a rack 15, and the gear is meshed with the rack 15.

[0032] In this embodiment, the position of the device can be easily adjusted by setting the universal wheel 14, and it has a stronger mobility. After the position adjustment is completed, according to the position of the oil-immersed power transformer to be filled with oil, the motor 11 is turned on to rotate the gear. Since the gear is engaged with the rack 15, the slide 1 and other components slide along the guide rail 10.

[0033] Furthermore, the slide 1 is rotatably connected to a rotating shaft 16, and the rotating shaft 16 is fixedly connected to one end of a swing arm 17, such as Figure 2 and Figure 3 As shown, the swing arm 17 is arranged in two parallel positions;

[0034] The other end of the swing arm 17 is rotatably connected to one end of the swing arm 2 18, and the other end of the swing arm 2 18 is rotatably connected to the movable plate 2;

[0035] The slide 1 is rotatably connected to a second rotating shaft 19, the second rotating shaft 19 is fixedly connected to one end of a third swing arm 20, the other end of the third swing arm 20 is rotatably connected to one end of a fourth swing arm 21, and the other end of the fourth swing arm 21 is rotatably connected to the movable plate 2;

[0036] The axis of the first rotating shaft 16 is vertical, and the axis of the second rotating shaft 19 is horizontal;

[0037] Further, the rotating shaft 16 is fixedly connected with a worm gear 22;

[0038] The slide 1 is fixedly connected with a motor 23, and the output end of the motor 23 is a worm 24 meshing with the worm wheel 22;

[0039] In this embodiment, if Figure 2 and Figure 3As shown, the axis of the rotating shaft 16 is vertical, and the axis of the rotating shaft 2 19 is horizontal, so the moving plate 2 can slide along the Z axis relative to the slide 1. When the moving plate 2 slides along the Z axis relative to the slide 1, in order to adapt to the change in the distance between the moving plate 2 and the Z axis, the angle between the swing arm 1 17 and the swing arm 2 18 changes, and at the same time, the angle between the swing arm 3 20 and the swing arm 4 21 changes;

[0040] When adjusting the position of the moving plate 2 , the motor 2 23 is operated to rotate the worm 24 , thereby controlling the worm wheel 22 to rotate. The worm wheel 22 drives the rotating shaft 16 and the swing arm 17 to rotate, thereby controlling the movement of the moving plate 2 .

[0041] Furthermore, it also includes a hose 25, one end of which is connected to the oil gun 3, and the other end of which is connected to the output end of an external oil pump, and a relatively large length is reserved to accommodate the movement of the oil gun 3 on the X-axis;

[0042] And the hose 25 passes through the moving plate 2, the swing arm 1 17 and the swing arm 2 18;

[0043] Furthermore, the top of the movable plate 2, the swing arm 1 17 and the swing arm 2 18 located above are all provided with a C-shaped buckle 26, and the hose 25 is clamped on the C-shaped buckle 26;

[0044] In this embodiment, when the movable plate 2 moves, it drives the swing arm 17 and the swing arm 2 18 to rotate. Since the hose 25 is clamped on the C-shaped buckle 26, the hose 25 is driven to partially rotate adaptively. The purpose of such a setting is to limit the hose 25 and prevent the hose 25 from being entangled.

[0045] Further, the slide 1 is fixedly connected to the stabilizing frame 27, and the stabilizing frame 27 is rotatably connected to the rotating shaft 16;

[0046] In this embodiment, the stabilizing frame 27 is provided to improve the rotation stability of the rotating shaft 16.

[0047] The utility model discloses an oil-immersed power transformer oil filling device. When working, the oil-immersed power transformers to be filled with oil are arranged one by one. Since the oil gun 3 can move along the XYZ axis, the operator can control the oil gun 3 to automatically insert the oil outlet into the oil filling port of the oil-immersed power transformer to fill the oil. Compared with the prior art, the user does not need to hold the oil gun 3 to fill the oil, which greatly improves the oil filling efficiency.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
