Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric transformer technology, and more specifically, to an oil storage tank for electric transformers. Background Technology
[0002] An electric transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. It is widely used in industry, agriculture, transportation, urban communities, and other fields. The transformer oil tank is used to store transformer oil.
[0003] For example, CN221327496U discloses a transformer oil storage tank. The key technical points of this tank are: it includes an oil storage tank body, with a connecting pipe fixedly connected to the outer surface of the body, and a screening and filtering structure installed on the upper surface of the connecting pipe; the screening and filtering structure includes a cover, a shell, and a filter assembly; the shell is a single-sided closed cylinder, with external threads at its port, allowing it to be movably installed with the cover via these threads; the filter assembly is installed inside the shell; the filter assembly includes a mounting bracket, a clamping plate, and a magnetic rod. The mounting frame is equipped with a filter plate and a filter plate. Several clamping plates are fixedly connected to the mounting frame, and a filter plate is installed between every two clamping plates. A magnetic rod is installed on the lower surface of the mounting frame, and the magnetic rod penetrates the filter plate and extends downward. The main function is to set up a screening and filtering structure. When the external oil flows into the interior of the housing through the oil inlet pipe, the magnetic rod first adsorbs the ferrous impurities in the oil. Then the oil passes through multiple layers of filter plates in sequence. The filter plates can screen and filter the non-ferrous impurities in the oil, achieving a better filtering effect and extending the service life of the transformer.
[0004] The aforementioned electric transformer oil tank also has some shortcomings: since the electric transformer oil tank does not have an internal wall cleaning function, once impurities adhere to the inner wall of the oil tank, it will affect the use of the oil tank and thus reduce the practicality of the device. Utility Model Content
[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide an oil storage tank for electric transformers. By setting up a cleaning component, when impurities adhere to the inner wall of the oil storage tank, the centrifugal pump inside the cleaning component is activated. The centrifugal pump then transports the cleaning liquid stored inside the storage tank to the connecting bend pipe through a stable connecting pipe. The connecting bend pipe then transports the cleaning liquid to the rectangular connecting pipe. Finally, the cleaning nozzle sprays out the cleaning liquid to clean the inner wall of the oil storage tank, thereby facilitating the reuse of the oil storage tank and solving the problems existing in the prior art.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an oil storage tank for an electric transformer, including an oil storage tank body, a cleaning component connected to the back of the oil storage tank body, a drain pipe connected to the bottom of the side wall of the oil storage tank body, two limiting grooves symmetrically opened along the center on one side inside the drain pipe, a hydraulic telescopic rod detachably installed on one side inside the limiting groove, a connecting plate fixedly connected to one end of the hydraulic telescopic rod, and a filter screen fixedly connected to the side wall of the connecting plate.
[0007] The hydraulic telescopic rods are of two lengths, the extension length of the hydraulic telescopic rods is greater than the length of the limiting slide groove, and the length of the limiting slide groove is less than the length of the sewage pipe.
[0008] The surface of the connecting plate is adapted to the interior of the limiting groove, and the surface of the filter screen is adapted to the interior of the drain pipe.
[0009] The cleaning assembly includes a stabilizing plate, a centrifugal pump, and a stabilizing connecting pipe. The centrifugal pump is fixedly connected to the upper surface of the stabilizing plate, and the input end of the centrifugal pump is connected to the stabilizing connecting pipe.
[0010] One end of the stabilizing connecting pipe is connected to a liquid storage tank, and the middle of the top of the liquid storage tank is connected to an inlet pipe. The inside of the liquid storage tank is filled with cleaning liquid.
[0011] The centrifugal pump has a connecting bend at its output end, and one end of the connecting bend is connected to a rectangular connecting pipe.
[0012] The bottom end of the rectangular connecting pipe is connected to multiple cleaning nozzles in a rectangular array, and the surface of the rectangular connecting pipe is connected to the top of the inner wall of the oil storage tank.
[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0014] 1. In the above scheme, the electric transformer oil storage tank is equipped with a cleaning component. When impurities adhere to the inner wall of the oil storage tank body, the centrifugal pump inside the cleaning component is started to work. Then, the centrifugal pump will transport the cleaning liquid stored in the storage tank to the connecting bend pipe through the stable connecting pipe. Then, the connecting bend pipe will transport the cleaning liquid to the rectangular connecting pipe. Finally, the cleaning nozzle will spray the cleaning liquid to clean the inner wall of the oil storage tank body, thereby facilitating the reuse of the oil storage tank body.
[0015] 2. In the above scheme, the electric transformer oil storage tank is equipped with a hydraulic telescopic rod. When the filter screen becomes clogged, the hydraulic telescopic rod is activated, causing it to move the connecting plate. Because the side wall of the connecting plate is connected to the side wall of the filter screen, the movement of the connecting plate can move the filter screen until it is moved out of the drain pipe, making it easier for workers to clean the clogged filter screen. Furthermore, because the hydraulic telescopic rod has an automatic extension and retraction function, it facilitates the disassembly of the filter screen, thereby improving the working efficiency of the device.

[0021] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.
[0022] Example 1:
[0023] Please see Figure 1-3 An electric transformer oil tank includes an oil tank body 1. A cleaning component 2 is connected to the back of the oil tank body 1. A drain pipe 3 is connected to the bottom of the side wall of the oil tank body 1. Two limiting grooves 4 are symmetrically opened along the center on one side of the inside of the drain pipe 3. A hydraulic telescopic rod 5 is detachably installed on one side of the inside of the limiting groove 4. A connecting plate 6 is fixedly connected to one end of the hydraulic telescopic rod 5. A filter screen 7 is fixedly connected to the side wall of the connecting plate 6.
[0024] There are two hydraulic telescopic rods 5. The extension length of the hydraulic telescopic rods 5 is greater than the length of the limiting slide 4. The length of the limiting slide 4 is less than the length of the drain pipe 3. The surface of the connecting plate 6 is adapted to the interior of the limiting slide 4. The surface of the filter screen 7 is adapted to the interior of the drain pipe 3. The cleaning assembly 2 includes a stabilizing plate 21, a centrifugal pump 22 and a stabilizing connecting pipe 23. The centrifugal pump 22 is fixedly connected to the upper surface of the stabilizing plate 21. The input end of the centrifugal pump 22 is connected to the stabilizing connecting pipe 23. One end of the stabilizing connecting pipe 23 is connected to the liquid storage tank 24. The middle of the top of the liquid storage tank 24 is connected to the liquid inlet pipe 25. The inside of the liquid storage tank 24 is filled with cleaning liquid. The output end of the centrifugal pump 22 is connected to the connecting bend pipe 26. One end of the connecting bend pipe 26 is connected to the rectangular connecting pipe 27. The bottom end of the rectangular connecting pipe 27 is connected to multiple cleaning nozzles 28 in a rectangular array. The surface of the rectangular connecting pipe 27 is connected to the top of the inner wall of the oil storage tank body 1.
[0025] Benefits: The installation of the drain pipe 3 facilitates the removal of impurities from the inside of the oil storage tank 1 after rinsing, thereby enhancing the practicality of the device.
[0026] The working process of this utility model is as follows:
[0027] In order to facilitate the use of the oil storage tank of the electric transformer, a cleaning component 2 is provided. When impurities adhere to the inner wall of the oil storage tank 1, the centrifugal pump 22 inside the cleaning component 2 is started to work. Then, the centrifugal pump 22 will transport the cleaning liquid stored in the storage tank 24 to the connecting bend 26 through the stable connecting pipe 23. Then, the connecting bend 26 will transport the cleaning liquid to the rectangular connecting pipe 27. Finally, the cleaning nozzle 28 will spray the cleaning liquid to clean the inner wall of the oil storage tank 1, thereby facilitating the reuse of the oil storage tank 1.
[0028] In the above scheme, to prevent the filter screen 7 from clogging during use, the oil storage tank of the electric transformer is equipped with a hydraulic telescopic rod 5. When the filter screen 7 becomes clogged, the hydraulic telescopic rod 5 is activated, causing the connecting plate 6 to move. Since the side wall of the connecting plate 6 is connected to the side wall of the filter screen 7, the movement of the connecting plate 6 can move the filter screen 7 until it is moved out of the drain pipe 3, making it easier for staff to clean the clogged filter screen 7. Furthermore, because the hydraulic telescopic rod 5 has an automatic telescopic function, it facilitates the disassembly of the filter screen 7, thereby improving the working efficiency of the device.
