[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] See also Figures 1 to 6 In the present invention, a transformer shell high-efficiency paint dipping device includes a base 1, two conveying rails 2 are fixedly installed on the base 1, and a carrier block 3 arranged at equal distances is installed on the top between the two conveying rails 2, an I-shaped frame 4 is fixedly installed on the base 1, and a vertical hydraulic cylinder 5 is installed on the I-shaped frame 4. A connecting block 6 is fixedly installed at the bottom end of the vertical hydraulic cylinder 5, and a frame mechanism 7 for vertically extending into the interior of the transformer shell is fixedly connected to the bottom of the connecting block 6, and positioning mechanisms 8 are fixedly installed on both sides of the base 1.

[0020] The frame mechanism 7 includes an outer box 71, an inner box 72, two drainage mechanisms 73 and a pumping mechanism 74. The top of the outer box 71 is fixedly connected to the connecting block 6, and the outer side of the inner box 72 is fixedly connected to the outer box 71 through a connecting rod. The two drainage mechanisms 73 are respectively installed on both sides of the inner box 72 and communicate with the outside through the outer box 71. The pumping mechanism 74 is installed on the outside of the connecting block 6, and the input end of the pumping mechanism 74 is connected to the outside of the outer box 71, and the output end of the pumping mechanism 74 is connected and cooperated with the inside of the inner box 72.

[0021] In the present invention, the two conveying rails 2 on the base 1 are used as the conveying structure to place the transformer shell on the carrier block 3, and the conveying rails 2 are started to drive the carrier block 3 to move so as to drive the transformer shell to be directly below the frame mechanism 7, and then the vertical hydraulic cylinder 5 is started to drive the frame mechanism 7 to descend until it completely enters the interior of the transformer shell. At this time, the frame mechanism 7 occupies a large amount of space inside the transformer shell, and a three-dimensional gap is formed between the outer side of the frame mechanism 7 and the interior of the transformer shell so that the paint liquid can flow normally inside, and then the two pumping mechanisms 74 are started to synchronously pump out the paint liquid from the inside of the inner box 72 so that it quickly fills the gap between the outer box 71 and the inside of the transformer shell, thereby reducing the flow of the paint liquid and ensuring comprehensive infiltration, and then the drainage mechanism is started. 73 draws the filled paint liquid back to the interior of the inner box 72 for recycling. In this process, there is no need to move and tilt the transformer shell, which can be completed in one go. As a result, the device can reduce the flow rate of paint liquid, improve the paint immersion efficiency, and have higher operating efficiency. It also does not require the transformer shell to be moved, thereby reducing production energy consumption and achieving the advantages of cost reduction and efficiency improvement. It solves the problem that the internal paint immersion in the prior art still adopts the method of filling and soaking the interior of the shell, and then drawing out the paint liquid inside, or turning the shell over and dumping it. In this process, firstly, due to the large space inside the shell, a large amount of paint needs to be injected, and repeated dumping is very time-consuming and labor-intensive, and the efficiency is low. In addition, due to the large weight of the shell itself, the dumping type drainage requires a high energy consumption drive, resulting in high energy consumption.

[0022] See also Figure 1 and Figure 2 , wherein: the liquid extraction mechanism 74 includes a liquid extraction tube 741, a liquid extraction pump 742 and a liquid discharge head 743, one end of the liquid extraction tube 741 extends downward to the bottom of the inner side of the inner box 72, the outer side of the liquid extraction pump 742 is fixedly connected to the outer side of the inner box 72, the input end of the liquid extraction pump 742 is fixedly connected to the top end of the liquid extraction tube 741, and the output end of the liquid extraction pump 742 is fixedly connected to the liquid discharge head 743.

[0023] In the present invention, the paint liquid in the inner box 72 is pumped out through the liquid pumping pipe 741 by starting the liquid pumping pump 742 and injected into the transformer housing through the liquid discharge head 743, so that the double-side operation efficiency is higher.

[0024] See also Figure 1 and Figure 3 , wherein: the drainage mechanism 73 includes a drainage pump 731, a three-way pipe 732, a reflux pipe 733 and two liquid extraction heads 734, the outer side of the drainage pump 731 is fixedly connected to the outer side of the connecting block 6, the input end of the drainage pump 731 is fixedly connected to the top of the three-way pipe 732, the other two ends of the three-way pipe 732 are fixedly connected to the outer box 71 through the two liquid extraction heads 734, and the output end of the drainage pump 731 is connected to the inner box 72 through the reflux pipe 733.

[0025] In the present invention, the drainage pump 731 is started to pump the excess paint liquid back to the interior of the inner box 72 from a low position using the three-way pipe 732 and the liquid pumping head 734, thereby achieving drainage and reflux, and realizing recycling.

[0026] See also Figure 1 , wherein: a liquid adding hopper 61 is fixedly connected to the interior of the connecting block 6, the bottom end of the liquid adding hopper 61 passes downward through the outer box 71 and is fixed to the interior of the inner box 72, and the right end of the reflux pipe 733 is connected and fixed to the liquid adding hopper 61.

[0027] In the present invention, the liquid adding hopper 61 facilitates the addition of paint liquid to the inner box 72 and facilitates the reflux of liquid in the reflux pipe 733 .

[0028] See also Figure 1 and Figure 4 , wherein: an adsorption sponge block 711 is fixedly connected to the bottom of the outer box 71 , and inclined surfaces 712 are provided on both sides of the bottom of the adsorption sponge block 711 .

[0029] In the present invention, through the adsorption sponge block 711, when the outer box 71 enters the interior of the transformer housing, the bottom of the adsorption sponge block 711 contacts the bottom of the transformer housing, and the paint liquid will fill the three-dimensional gaps on both sides. Then, as the excess paint liquid is extracted, paint liquid will remain at the low position. As the outer box 71 rises, the inclined surfaces 712 on both sides of the adsorption sponge block 711 will first separate from the bottom surface of the transformer housing, and the excess paint liquid will gradually infiltrate along the inner bottom surface of the housing, while the excess will be adsorbed by the expanded adsorption sponge block 711 until the adsorption sponge block 711 is completely separated from the inner bottom surface of the housing, which can ensure that the excess paint liquid is completely discharged and the inner side of the transformer housing is completely infiltrated. During the infiltration operation, the adsorption sponge block 711 will contact the bottom surface of the transformer housing and be squeezed to squeeze out the excess paint liquid, so that the adsorption can be continuously and repeatedly performed during the rise without the need for excess operation, which is efficient and convenient.

[0030] See also Figure 1 , wherein: the outer side of the movable end of the vertical hydraulic cylinder 5 is fixedly connected to two stabilizing rods 51 , and the opposite ends of the two stabilizing rods 51 are slidably connected to the inner side of the I-shaped frame 4 .

[0031] In the present invention, the movable end of the vertical hydraulic cylinder 5 is strengthened and assisted by the stabilizing rod 51, so that the operation of the vertical hydraulic cylinder 5 is more stable.

[0032] See also Figure 1 , wherein: the positioning mechanism 8 includes a horizontal cylinder 81 and a clamping block 82 , one end of the horizontal cylinder 81 is fixedly connected to the inner side of the I-frame 4 , and the movable end of the horizontal cylinder 81 is fixedly connected to the clamping block 82 .

[0033] In the present invention, the clamping block 82 is driven by starting the horizontal cylinder 81 to clamp and stabilize the outer side of the transformer housing moved to the processing position from both sides, so that it remains stable during the infiltration operation.

[0034] See also Figure 1 , wherein: a rubber pad 811 is fixedly connected to the side of the clamping block 82 away from the horizontal cylinder 81 .

[0035] In the present invention, the outer side of the transformer housing is protected by the rubber pad 811 to avoid scratches caused by clamping.

[0036] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
