[0002] A power transformer is an electrical device mainly used to convert a certain value of AC voltage or current into a voltage or current with the same frequency but a different value in order to transmit electrical energy. Oil leakage in transformers not only seriously affects their appearance and causes economic losses, but also brings serious consequences such as operational risks, safety risks, and misjudgment risks. Therefore, transformers should be inspected regularly to detect and deal with oil leakage problems in a timely manner.

[0003] Chinese patent CN221861408U discloses a power transformer with an oil leakage prevention function. This technical solution monitors oil leakage during the operation of the transformer using an oil level gauge and a temperature sensor. When oil leakage occurs in the insulating bushing, the leaked oil is drained through an oil storage tank and a diversion tank, and the leaked oil from the heat sink is collected and stored through a diversion plate and a receiving plate. This facilitates the rapid recovery and cleaning of the leaked oil, prevents the transformer oil from dripping into the external environment, and improves the safety of the transformer operation.

[0004] However, the power transformer oil tank with the anti-leakage structure does not have the function of quickly and thoroughly draining the collected seepage oil during use, resulting in low collection efficiency of seepage oil by staff in the later stage, which is not conducive to the use of seepage oil recycling.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] First Embodiment

[0026] Please see Figure 1-5 This utility model provides a technical solution: a power transformer oil tank with a leak-proof structure, including an oil tank body 1, a plurality of heat dissipation fins 2 fixedly connected to the side wall of the oil tank body 1, a conical bucket 12 fixedly connected to the bottom of the oil tank body 1, and a filter screen plate 13 surrounding the plurality of heat dissipation fins 2 provided on the top of the conical bucket 12.

[0027] The bottom of the conical bucket 12 is connected to a receiving box 15. One end face of the receiving box 15 is connected to a drain pipe 11. The inner cavity of the receiving box 15 is provided with a scraper 22 that moves horizontally through a transmission mechanism. The side wall of the scraper 22 is in contact with the inner wall of the receiving box 15. Several insulating sleeves 3 are provided on the top of the oil tank body 1.

[0028] In this embodiment, after the filter screen 13 collects some of the leaked oil, it can be guided by the conical bucket 12 to collect the oil into the inner cavity of the container 15. When it is necessary to drain the oil inside the container 15 later, the drain pipe 11 can be opened, and after the transmission mechanism works, the scraper 22 can be moved. The movement of the scraper 22 reduces the space inside the container 15, thereby improving the efficiency of oil drainage.

[0029] During the movement of the scraper 22, the inner wall of the container 15 is scraped, thereby improving the thoroughness of oil discharge and facilitating the subsequent oil recovery work by the staff.

[0030] Multiple heat dissipation fins 2 increase the contact area between the oil tank body 1 and the air, thereby improving the heat dissipation efficiency of the oil tank body 1, enhancing the protection of the oil tank body 1, and extending the service life of the oil tank body 1.

[0031] Then it can be set.

[0032] Furthermore, mounting bases 18 are fixedly connected to both ends of the bottom of the container 15, and an observation window 17 is provided on the front side of the container 15. The observation window 17 makes it easy to view the storage capacity inside the container 15, and the mounting base 18 makes it easy to fix and install the oil tank body 1.

[0033] Furthermore, several reinforcing ribs 14 are fixedly connected between the bottom of the side wall of the oil tank body 1 and the top of the conical bucket 12, and several lifting rings 4 are fixedly connected to the top of the oil tank body 1. The reinforcing ribs 14 strengthen the connection between the conical bucket 12 and the oil tank body 1, extend the service life of the device, and the lifting rings 4 facilitate the lifting of the device and facilitate the installation and operation of the device.

[0034] Furthermore, an alarm 6 is fixedly connected to the top of the oil tank body 1. A liquid level sensor 7 and a temperature sensor 5 are respectively installed on the oil tank body 1. The liquid level sensor 7 and the temperature sensor 5 facilitate the monitoring of the oil level and temperature inside the oil tank body 1. The alarm 6 facilitates the alarm when the preset value is exceeded during the use of the device.

[0035] Furthermore, a collecting groove 8 is provided on the top of the oil tank body 1, the collecting groove 8 is covered with multiple insulating sleeves 3, and drip outlets 10 are provided at the four corners of the top of the oil tank body 1. Guide grooves 9 communicating with drip outlets 10 are provided at the four corners of the inner wall of the collecting groove 8.

[0036] In this embodiment, the collecting groove 8 can collect oil leaking from the weld between the insulating sleeve 3 and the oil tank body 1, and guide the oil to the corresponding position of the drip port 10 through the guide groove 9. The oil can then drip into the corresponding position of the filter screen plate 13 through the drain pipe 11, thereby collecting and gathering the oil leaking from the top of the oil tank body 1.

[0037] Second Embodiment

[0038] Please refer to Figure 4 Based on the same concept as the first embodiment described above, the transmission mechanism includes a motor 16, a threaded rod 19, and a threaded sleeve 21. The motor 16 is fixedly connected to the other end face of the receiving box 15, the threaded rod 19 is rotatably disposed in the inner cavity of the receiving box 15, and the other end extends to the outside of the receiving box 15 and is fixedly connected to the output shaft of the motor 16.

[0039] The threaded sleeve 21 is threaded to the surface of the threaded rod 19, and the scraper 22 is fixedly connected to the side wall of the threaded sleeve 21. The upper part of the inner cavity of the receiving box 15 is horizontally fixedly connected to the guide rod 20, and the scraper 22 is slidably sleeved on the surface of the guide rod 20.

[0040] In this embodiment, after the motor 16 starts working, it can drive the threaded rod 19 to rotate. Then, after the threaded sleeve 21 moves along the surface of the threaded rod 19, the guide rod 20 guides and limits the movement, which in turn drives the scraper 22 to scrape the inner wall surface of the receiving box 15.

[0041] The working principle and usage process of this utility model are as follows: After installation, the collecting groove 8 can collect oil leaking from the weld between the insulating sleeve 3 and the oil tank body 1. Guided by the guide groove 9, the oil is directed to the corresponding position of the drip outlet 10. The oil can then drip through the drain pipe 11 into the corresponding position of the filter screen 13, thereby collecting and converging the oil leaking from the top of the oil tank body 1. After leakage at the weld between the heat dissipation fins 2 and the oil tank body 1, the oil can slide down the side wall of the oil tank body 1, and the filter screen... After the plate 13 collects the leaked oil, it can be guided by the conical hopper 12 to collect the oil into the inner cavity of the container 15. When it is necessary to drain the oil inside the container 15 later, the drain pipe 11 can be opened. After the transmission mechanism works, the scraper 22 can be moved. The movement of the scraper 22 reduces the space inside the container 15, thereby improving the oil drainage efficiency. The scraper 22 also scrapes the inner wall of the container 15 during its movement, thereby improving the thoroughness of oil drainage.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
