[0002] Power distribution equipment refers to all kinds of equipment used in power supply and distribution systems. Among them, there is an oil-immersed power transformer. During the operation of an oil-immersed power transformer, it needs to dissipate heat through its surface radiator and heat dissipation holes.

[0003] The existing Chinese patent with publication number CN210489376U discloses an oil-immersed transformer, which includes a main body, radiators fixedly installed at the front and rear ends and the left and right ends of the main body, a high-voltage bushing fixedly installed at the upper end of the main body, a low-voltage bushing fixedly installed at the front end of the high-voltage bushing, lifting rings fixedly installed at the front and rear ends of the upper end of the main body, a connecting seat fixedly installed at the left end of the upper end of the main body, an oil tank fixedly installed at the upper end of the connecting seat, an oil inlet fixedly installed at the upper end of the oil tank, an oil inlet pipe fixedly connected to the left end of the lower end of the oil tank, and a return oil pipe fixedly connected to the lower part of the front end of the oil tank.

[0004] Regarding the aforementioned technologies, the applicant believes that in current oil-immersed transformers, the surface of the radiator is prone to accumulating a large amount of dust after prolonged use, which reduces the heat dissipation efficiency of the radiator and affects the normal operation of the transformer. Therefore, improvements are still needed. Utility Model Content

[0005] In order to clean the radiator, reduce the dust adhering to the radiator, improve the heat dissipation efficiency of the radiator, and enable the transformer to work normally, this application provides an oil-immersed transformer that is easy to clean.

[0006] The oil-immersed transformer that is easy to clean, as provided in this application, adopts the following technical solution: An easy-to-clean oil-immersed transformer includes a transformer body and a radiator disposed on the outer wall of the transformer body. The radiator includes a plurality of heat dissipation fins and a cleaning mechanism is provided on the heat dissipation fins. The cleaning mechanism includes a main cleaning side plate and a lifting seat, as well as a secondary cleaning side plate and a support seat. The lifting seat is installed on the heat dissipation fins and is raised and lowered by a lifting structure. The main cleaning side plate is fixed to the lifting seat at intervals. The support seat is installed on the lifting seat. The secondary cleaning side plate is fixed to the support seat at intervals. The secondary cleaning side plate and the main cleaning side plate are arranged opposite to each other and are respectively close to the two sides of the heat dissipation fins.

[0007] By adopting the above technical solution, the lifting seat supports the main cleaning side plate, and the support seat supports the secondary cleaning side plate. The lifting of the lifting seat drives the main cleaning side plate and the secondary cleaning side plate to move up and down on the heat sink, thereby achieving the purpose of conveniently cleaning the heat sink, reducing the dust attached to the heat sink, improving the heat dissipation efficiency of the heat sink, and enabling the transformer to work normally.

[0008] Preferably, the lifting structure includes a drive chain and a drive gear installed on the side wall of the transformer body. The drive gear is respectively set and rotatably connected to the upper and lower ends of the side wall of the transformer body. The drive chain meshes with the drive gear, and the rotation of the drive gear drives the drive chain to move. The drive chain is arranged opposite to the two ends of the side wall of the transformer body, and the two ends of the lifting seat are respectively connected to the corresponding drive chain. A crank is fixed on the lower drive gear.

[0009] By adopting the above technical solution, the rotation of the drive gear drives the rotation of the drive chain belt. The lifting seat is connected to the drive chain belt and slides along the side wall of the transformer body, so that the drive chain belt drives the lifting seat to rise and fall, thereby driving the cleaning main side plate and the cleaning secondary side plate to clean the heat sink.

[0010] Preferably, the lifting seat has a corresponding clamping block at one end near the drive chain, and one clamping block is movable on the lifting seat, while the opposite clamping block clamps the corresponding drive chain and is locked by clamping bolts.

[0011] By adopting the above technical solution, the lifting seat is clamped and positioned on the drive chain by the clamping block, so as to achieve the effect of the drive chain driving the lifting seat to rise and fall.

[0012] Preferably, the lifting seat has a receiving groove for accommodating the support seat, and the lifting seat has an installation groove corresponding to the cleaning sub-side plate that communicates with the receiving groove, and the cleaning sub-side plate is accommodated in the installation groove; the support seat can slide and be positioned along the receiving groove, and the cleaning sub-side plate can move within the installation groove.

[0013] By adopting the above technical solution, the support base and the cleaning sub-side plate are housed in the corresponding receiving groove and mounting groove and can be adjusted movably, thereby improving the tightness of the clamping of the cleaning main side plate and the cleaning sub-side plate on the heat sink, while avoiding excessive clamping that makes it difficult to move, thus achieving the purpose of improving the cleaning effect.

[0014] Preferably, the support seat after the activity is positioned on the lifting seat by a positioning element.

[0015] Preferably, the positioning element is a locking bolt, which is threaded to both ends of the support base and abuts and is positioned at the corresponding position in the receiving groove.

[0016] Preferably, a sponge pad is fixed to both the main cleaning side plate and the secondary cleaning side plate.

[0017] By adopting the above technical solution, the sponge pad can be easily deformed to better adhere to the side wall of the heat sink for cleaning, thereby improving the cleaning effect.

[0018] Preferably, the bottom of the lifting seat is fixed with handles at intervals.

[0019] In summary, this application includes at least one of the following beneficial technical effects: The lifting seat supports the main cleaning side plate, and the support seat supports the secondary cleaning side plate. The lifting of the lifting seat drives the main cleaning side plate and the secondary cleaning side plate to move up and down on the heat sink, thereby achieving convenient cleaning of the heat sink, reducing the dust attached to the heat sink, improving the heat dissipation efficiency of the heat sink and enabling the transformer to work normally. The rotation of the drive gear drives the rotation of the drive chain belt. The lifting seat is connected to the drive chain belt and slides along the side wall of the transformer body, so that the drive chain belt drives the lifting seat to rise and fall, and drives the cleaning main side plate and the cleaning secondary side plate to clean the heat sink. The support base and the cleaning sub-side plate are housed in the corresponding receiving slots and mounting slots and can be adjusted to improve the tightness of the clamping of the cleaning main side plate and the cleaning sub-side plate on the heat sink, while avoiding excessive clamping that makes it difficult to move, thereby improving the cleaning effect.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] This application discloses an oil-immersed transformer that is easy to clean, referring to... Figure 1 It includes a transformer body 1 and a radiator 2 installed on the outer wall of the transformer body 1. The radiator 2 includes several heat dissipation fins 21, which have a good heat dissipation effect.

[0024] Reference Figure 1 , 2The heat sink 21 is provided with a cleaning mechanism 3. The cleaning mechanism 3 includes a main cleaning side plate 31, a lifting seat 32, a secondary cleaning side plate 33, and a support seat 34. The lifting seat 32 is installed on the heat sink 21. The main cleaning side plate 31 is fixed to the lifting seat 32 at intervals and corresponds to the side wall of the same side of each heat sink 21. The support seat 34 is installed on the lifting seat 32. The secondary cleaning side plate 33 is fixed to the support seat 34 at intervals. The secondary cleaning side plate 33 and the main cleaning side plate 31 are arranged opposite to each other and are tightly attached to both sides of the heat sink 21.

[0025] Reference Figure 1 , 2 Both the main cleaning side plate 31 and the secondary cleaning side plate 33 are fixed with sponge pads. The sponge pads are easily deformable, so they can better adhere to the side wall of the heat sink 21 for cleaning and improve the cleaning effect. The bottom of the lifting seat 32 is fixed with handles 8 at intervals, which can also be manually driven to lift.

[0026] Reference Figure 1 , 2 The lifting seat 32 has a receiving groove 321 for accommodating the support seat 34, and the lifting seat 32 has a mounting groove 322 corresponding to the cleaning secondary side plate 33, which communicates with the receiving groove 321. The cleaning secondary side plate 33 is accommodated in the mounting groove 322. The support seat 34 can slide and be positioned along the receiving groove 321, and the cleaning secondary side plate 33 can move within the mounting groove 322, thereby adjusting the relative clamping distance between the cleaning main side plate 31 and the cleaning secondary side plate 33, so as to better fit the heat sink 21 side wall, and avoid clamping too tightly and making it difficult to move.

[0027] Reference Figure 2 After the activity, the support base 34 is positioned on the lifting base 32 by the positioning component; the positioning component is the locking bolt 4, which is threaded to both ends of the support base 34 and abuts and is positioned in the corresponding position in the receiving groove 321, thereby conveniently fixing the support base 34.

[0028] Reference Figure 1 , 3 The lifting seat 32 is raised and lowered by the lifting structure 5. The lifting structure 5 includes a drive chain belt 51 and a drive gear 52 installed on the side wall of the transformer body 1. The drive gear 52 is respectively set and rotatably connected to the upper and lower ends of the side wall of the transformer body 1. The drive chain belt 51 meshes with the drive gear 52. The rotation of the drive gear 52 drives the drive chain belt 51 to move. A protective cover 53 is fixed on the outside of the drive chain belt 51 and the drive gear 52.

[0029] Reference Figure 1 , 3The drive chain belt 51 is set opposite to each other at both ends of the side wall of the transformer body 1, and the two ends of the lifting seat 32 are respectively connected to the corresponding drive chain belt 51; a crank is fixed on the drive gear 52 located below, and the drive chain belt 51 is driven by rotating the crank to drive the drive gear 52 to rotate, thereby driving the cleaning main side plate 31 and the cleaning secondary side plate 33 to rise and fall on the heat sink 21 for cleaning.

[0030] Reference Figure 2 , 3 The lifting seat 32 is provided with a corresponding clamping block 6 at one end near the drive chain belt 51, and one clamping block 6 is movable in the lifting seat 32. The corresponding clamping block 6 is clamped on the corresponding drive chain belt 51 and locked by the clamping bolt 7. By clamping and positioning the lifting seat 32 on the drive chain belt 51 through the clamping block 6, the drive chain belt 51 drives the lifting seat 32 to rise and fall. This makes the lifting seat 32, the support seat 34, the main cleaning side plate 31 and the secondary cleaning side plate 33 detachable and can be used for cleaning different side walls of the transformer body 1.

[0031] Reference Figure 1 , 2 The heat sinks 21 located on the left and right sides of the oil-immersed transformer are relatively few. They can be cleaned manually by manually holding the handle 8 to drive the lifting seat 32 and the support seat 34.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
