The transformer can change the voltage to the required voltage value to meet the requirements of electrical energy transmission, distribution, and use. To ensure the stable operation of the transformer, it is usually necessary to ensure the stability of its internal structure. Currently, for the protection treatment of the pipelines inside the transformer, only fixing structures such as buckles are used. Although this method can improve the firmness of the structure, since the positions and angles of the buckles are fixed, it is not conducive to the layout of the pipelines.

An iron core is arranged inside the housing, and a low-voltage coil, a high-voltage coil, and a copper pipe are sequentially wound around the outside of the iron core. The low-voltage coil and the copper pipe are wound around the iron core according to a preset distance and number of turns. A high-voltage coil is arranged outside the low-voltage coil and the copper pipe, and an insulating part is arranged between the copper pipe and the high-voltage coil. The insulating part is tightly pressed by the high-voltage coil. A circulating water pump is arranged on one side of the housing. The circulating water pump is provided with an inlet valve and an outlet valve. The inlet and outlet of the circulating water pump are respectively connected to the two ends of the copper pipe through pipelines. The copper pipe and the pipelines are filled with a coolant. A groove for fixing the pipeline is arranged outside the housing, and a buckle capable of fastening the pipeline is arranged at the edge of the groove opening.

[0036] The beneficial effects of the present invention are as follows:

[0037] 1. By setting up a pipeline protection component, the present invention can install the pipeline in the first spherical arc-shaped part during assembly. By rotating the second spherical arc-shaped part, it slides out from one end of the arc-shaped sliding cavity and then inserts into the other end of the arc-shaped sliding cavity, so as to form a closed-loop structure with the first spherical arc-shaped part. Then, by screwing the fastening knob, the second spherical arc-shaped part is pressed and fixed by the ejector post, thus realizing the partial wrapping and limiting of the pipeline.

[0038] 2. Since the present invention is provided with arc-shaped seats, after the two arc-shaped seats are closed, an annular cavity for accommodating the first spherical arc-shaped part and the second spherical arc-shaped part is formed on the inner wall. The first spherical arc-shaped part and the second spherical arc-shaped part are movably installed in the annular cavity. Therefore, it has a certain tilting ability and can better cope with external force interference and other situations, improving the practicability.

[0039] 3. By setting up structures such as arc-shaped limiting ridges, the present invention can play a limiting role, preventing the second spherical arc-shaped part from deflecting too much in the annular cavity of the arc-shaped seat, ensuring the protection effect on the pipeline and improving the reliability.

[0040] 4. By setting up structures such as a guide frame and a sliding cylinder, the present invention can facilitate the adjustment of the position of the arc-shaped seat, improving the practicability; by setting up structures such as a fixing part, after adjusting the position of the arc-shaped seat, by screwing the adjusting knob, the toothed plate moves towards the positioning tooth, and then the engaging teeth are engaged with the positioning tooth, thus realizing the fixation of the position of the arc-shaped seat.

[0041] 5. By setting up a first anti-slip gasket and a second anti-slip gasket, when the second spherical arc-shaped part and the first spherical arc-shaped part form a closed-loop state, the second anti-slip gasket and the first anti-slip gasket form a closed-loop state, better protecting the pipeline and improving the reliability; by setting up a clamping frame and a clamping groove, the pipeline can be clamped and fixed according to requirements, improving the practicability.

[0042] 6. By setting up a self-cleaning structure, when the transformer is set outdoors, based on the support of the spring, the plugging head can be at the same height as the drain port and block the drain port; the liquid collecting box can collect rainwater. As the collection amount increases, the liquid collecting box finally overcomes the friction between the plugging head and the drain port and the elastic force of the spring, causing the liquid collecting box to drop. During this period, the cleaning part can clean the heat sink; during the dropping process, since the drain port loses the blockage, the water body can continuously drain from the drain port and finally reset based on the elastic force of the spring.

[0043] 7. By providing a conical head with a diameter gradually decreasing in the vertically downward direction and an annular elastic sleeve, the present invention can block the drain opening with the annular elastic sleeve under normal conditions. When the liquid collection box descends and then resets, the conical head can play a reliable guiding role, enabling the liquid collection box to reset based on the spring's resilience and moving upward by overcoming the friction of the annular elastic sleeve due to inertia, so that the drain opening stays in the middle of the annular elastic sleeve to achieve resetting.

[0044] 8. By providing a runner and a cleaning brush, the present invention can clean the surface of the heat sink during the descent of the liquid collection box, improving the practicality. By providing structures such as a diversion groove and a cotton sleeve, when water is discharged from the drain opening, the diversion groove can be used to receive it. After the water is guided by the diversion groove, it flows to the cotton sleeve, and the cotton sleeve plays a certain role in guiding the flow, making it easier for the cleaning brush to be wetted, thus ensuring the cleaning effect.

[0063] By setting the pipeline protection component, during assembly, the pipeline can be installed in the first spherical arc-shaped part 18. By rotating the second spherical arc-shaped part 19, after it slides out from one end of the arc-shaped sliding cavity 30 and is inserted into the other end of the arc-shaped sliding cavity 30, a closed-loop structure is formed with the first spherical arc-shaped part 18. Then, by screwing the fastening knob 27, the second spherical arc-shaped part 19 is pressed and fixed by the ejector post 28, thereby realizing the partial wrapping and limiting of the pipeline;

[0077] By providing the first anti-slip gasket 29 and the second anti-slip gasket 25, when the second spherical arc-shaped part 19 and the first spherical arc-shaped part 18 form a closed-loop state, the second anti-slip gasket 25 and the first anti-slip gasket 29 can form a closed-loop state, which can better protect the pipeline and improve the reliability.

[0078] To better fix the pipeline; as Figure 3 shown, a clamping frame 14 is fixed to the bottom outer wall of the skeleton main body 10 by bolts, and linearly distributed clamping grooves 15 are provided on one side of the clamping frame 14;

[0082] Embodiment 2:

[0083] A pipeline protection framework for a transformer housing, as Figures 1-9 shown. To facilitate the automatic cleaning of the structure of the transformer housing 1, the following improvements are made on the basis of Embodiment 1: A heat sink 4 is integrally arranged on the outer side wall of the transformer housing 1 in a uniformly distributed manner; A self-cleaning mechanism is further installed on the transformer housing 1, and the self-cleaning mechanism includes:

[0084] A mounting plate 3, which is welded and fixed to the outer wall of one side of the transformer housing 1, and the same vertical rod 2 is fixed between the upper and lower two mounting plates 3 by bolts;

[0099] By providing structures such as the guide groove 39 and the cotton cover 41, when water is discharged from the drain outlet, the guide groove 39 can be used to receive it. After being guided by the guide groove 39, the water flows to the cotton cover 41. The cotton cover 41 plays a certain drainage role, making the cleaning brush 42 easier to be wetted, thereby ensuring the cleaning effect.

[0100] To improve reliability, Figure 8 As shown, the top outer wall of the lifting slide 33 is bonded with a pleated sleeve 6, the top outer wall of the pleated sleeve 6 is bonded to the bottom outer wall of the upper mounting plate 3, and the pleated sleeve 6 is located outside the spring 35;

[0101] By providing structures such as the pleated sleeve 6, a certain protective effect can be provided to structures such as the spring 35, thereby improving practicality.

[0103] By providing the annular buffer pad 31 and the annular buffer piece 32, the structure can be buffered, improving the reliability.
