[0037] Example

[0038] like Figure 1 and Figure 2 As shown, a combined transformer proposed by the utility model includes a transformer body 1.

[0039] Further, such as Figure 3As shown, the above transformer includes an oil collecting mechanism 2 for collecting waste oil in the transformer body 1, and the oil collecting mechanism 2 is installed below the transformer body 1. The oil collecting mechanism 2 includes a containing box 21, and the containing box 21 is used to contain waste oil. A connecting pipe 22 is installed on the top of the containing box 21, and the connecting pipe 22 is connected to the inside of the containing box 21. A connecting block 23 is also fixedly connected to the top of the connecting pipe 22, and a plurality of first through holes 24 are provided on the connecting block 23, which is convenient for passing bolts for installation and fixing. The connecting block 23 is fixedly connected to the bottom of the transformer body 1 through the first through holes 24, and the connecting block 23 and the first through holes 24 facilitate fixing the containing box 21 to the bottom of the transformer body 1, and a sealing ring is provided between the connecting block 23 and the transformer body 1 to enhance the sealing. A fixing ring 25 is installed on the outer ring of one end of the containing box 21, and the position of the fixing ring 25 is fixed. A side plate 26 is also provided on the side of the fixing ring 25 away from the connecting pipe 22. A second through hole 27 is provided on both the fixing ring 25 and the side plate 26. The fixing ring 25 and the side plate 26 are fixed together by using bolts to pass through the second through hole 27, so that they are tightly connected. At the same time, a sealing ring is provided between the fixing ring 25 and the side plate 26 to enhance the sealing performance and prevent the waste oil from leaking and polluting the environment. An oil drain port 28 is also provided at the bottom of the storage box 21 near one end of the side plate 26. The oil drain port 28 facilitates the discharge of waste oil in the storage box 21. A sealing cover 29 is threadedly connected to the oil drain port 28. The sealing cover 29 is used to seal the oil drain port 28. When there is a lot of waste oil in the storage box 21, it can be discharged by opening the sealing cover 29.

[0040] Furthermore, Figure 4As shown, the above transformer also includes an oil lowering assembly 3 for controlling the discharge of waste oil, and the oil lowering assembly 3 is installed in the oil collecting mechanism 2. The oil lowering assembly 3 includes a guide block 31 arranged in the connecting pipe 22, and the top of the guide block 31 is inclined and inclined toward the middle position. A slide groove 32 is provided in the guide block 31, and a partition plate 33 is slidably connected in the slide groove 32. A rubber sealing pad is provided on the inner wall of the slide groove 32, so that the sealing performance at the slide groove 32 is good and the oil above is not easy to leak down. The partition plate 33 passes through one end of the connecting pipe 22 and is fixedly connected to a moving plate 34, and the moving plate 34 moves synchronously with the partition plate 33. A push rod motor 35 is installed on the top of the containing box 21, and the output end of the push rod motor 35 is fixedly connected to the moving plate 34. The push rod motor 35 is used to drive the moving plate 34 to move after starting, and at the same time drive the partition plate 33 to slide in the slide groove 32. Two sets of first limiting rods 36 are also fixedly connected to the side of the moving plate 34 close to the push rod motor 35. The two sets of first limiting rods 36 move synchronously with the moving plate 34 and are respectively located on both sides of the push rod motor 35. The outer ring sliding sleeve of the first limiting rod 36 is provided with a first limiting sleeve 37. The first limiting sleeve 37 is fixedly connected to the top of the containing box 21, and is used for the first limiting rod 36 to slide in the first limiting sleeve 37 when following the movement of the moving plate 34. The limiting action of the first limiting rod 36 and the first limiting sleeve 37 makes the movement of the moving plate 34 smooth. The end of the first limiting rod 36 away from the moving plate 34 is also fixedly connected to a limiting disk 38, which is used for limiting to prevent the moving plate 34 from moving too far.

[0041] Finally, see Figure 4 and Figure 5 The above transformer is provided with an oil discharge assembly 4 for assisting in discharging the waste oil collected in the oil lowering assembly 3 for recycling, and the oil discharge assembly 4 is provided in the oil lowering assembly 3. The oil discharge assembly 4 includes a scraper 41 provided in the storage box 21, and a connecting rod 42 is fixedly connected to the side of the scraper 41 close to the side plate 26, and the connecting rod 42 moves synchronously with the scraper 41. A pull plate 43 is installed at one end of the connecting rod 42, and the pull plate 43 is convenient for pulling the connecting rod 42 to drive the scraper 41 to move and scrape out the solidified waste oil in the storage box 21. The side of the scraper 41 close to the side plate 26 is also fixedly connected to multiple groups of second limiting rods 44, and the second limiting rods 44 move synchronously with the scraper 41. The outer ring of the second limiting rod 44 is slidably sleeved with a second limiting sleeve 45, and the second limiting sleeve 45 is fixedly connected to the inner wall of the storage box 21. The second limiting rod 44 and the second limiting sleeve 45 are used to limit the scraper 41 when it moves, so as to prevent the scraper 41 from deviating during the movement.

[0042] In this embodiment, when there is too much waste oil in the transformer body 1, the push rod motor 35 is started. After the push rod motor 35 is started, its output end contracts and drives the moving plate 34 to move. Since the first limiting rod 36 fixedly connected to the side of the moving plate 34 is slidably connected to the first limiting sleeve 37, the moving plate 34 moves smoothly under the limiting action of the first limiting rod 36 and the first limiting sleeve 37 when moving. At this time, the partition plate 33 moves synchronously and slides in the slide groove 32, so that the waste oil above the guide block 31 flows downward into the storage box 21 for storage. After the waste oil in the transformer body 1 is drained, the push rod motor 35 is started, so that the push rod motor 35 extends and drives the partition plate 33 to slide in the slide groove 32 to block the guide block 31 again. When a certain amount of waste oil in the storage box 21 needs to be processed, the sealing cover 29 is rotated to open, so that the waste oil in the storage box 21 is discharged from the oil discharge port 28, and the waste oil is collected by a container to recover the cost, which effectively utilizes resources and prevents environmental pollution. In a cold environment, when the waste oil in the storage box 21 solidifies and is difficult to be discharged from the oil discharge port 28, the side plate 26 can be removed, and the pull plate 43 can be clamped with a tool and pulled outward. At this time, the pull plate 43 drives the scraper 41 to move synchronously through the connecting rod 42. At this time, the second limiting rod 44 installed on the side of the scraper 41 slides in the second limiting sleeve 45 for limiting, and the scraper 41 moves smoothly in the storage box 21 to scrape the waste oil in the storage box 21 for recycling.

[0043] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
