Description

Technical Field

[0001] The utility model relates to the technical field of power electronics, in particular to a self-cleaning transformer. Background Art

[0002] As an indispensable and important equipment in the power system, the transformer undertakes the key tasks of voltage conversion, power transmission and distribution. In order to ensure its normal operation and extend its service life, the heat dissipation of the transformer has always been a concern. As an important component of the transformer, the heat sink is designed to increase the heat dissipation area and improve the heat dissipation efficiency, thereby ensuring that the transformer can maintain a good temperature state when operating at high load.

[0003] In actual use of some existing transformers, the transformer heat sinks often face the problem of dust accumulation. Since the heat sink is usually arranged on the side of the transformer and its surface has a certain adsorption property, dust and particulate matter in the environment are easy to adhere to it. As time goes by, these dusts gradually accumulate to form a thick layer of dust scale, which not only affects the appearance of the heat sink, but more importantly, has an adverse effect on the normal operation of the transformer. First of all, the accumulation of dust will seriously affect the heat dissipation efficiency of the heat sink. The main function of the heat sink is to increase the heat dissipation area and speed up the heat exchange rate with the surrounding environment, thereby reducing the temperature of the transformer. However, when the heat sink is covered with dust, its heat dissipation area will be greatly reduced, and the heat exchange rate will also be reduced, resulting in a decrease in heat dissipation efficiency, which will cause the transformer to generate excessive heat during operation, thereby causing a series of problems. Utility Model Content

[0004] The purpose of the utility model is to provide a self-cleaning transformer to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A self-cleaning transformer comprises: a base, a transformer is fixed on the upper side of the base, a driving member is arranged on the lower side of the base, and a cleaning device is fixed on the upper side of the base;

[0007] The cleaning device comprises a shell, the upper side of the base is fixed with the shell, one side of the shell is fixed with a servo motor, and the inner side of the shell is provided with a cleaning component.

[0008] Preferably, the cleaning assembly includes a support, the support is fixed on the inner side of the outer shell, a plurality of groups of bearings are fixed on the upper side of the support, a plurality of groups of main gears are arranged on the inner side of the support, a plurality of groups of main gears are meshed with secondary gears, and brushes are fixed on the inner sides of the bearings, main gears and secondary gears.

[0009] Preferably, a set of main gears is fixed in the output direction of the servo motor.

[0010] As the servo motor rotates, the main gear also starts to rotate. Since the main gear and multiple sets of sub-gears set on the inner side of the support are meshed together, the sub-gears will also rotate accordingly. This gear transmission mechanism ensures that multiple main gears and sub-gears can rotate synchronously, thereby driving the brushes fixed on their inner sides to rotate and clean.

[0011] Preferably, the brush comprises a connecting roller, the inner sides of the bearing, the main gear and the auxiliary gear are all fixed with connecting rollers, one side of the connecting roller is fixed with a fixed roller, and the outer side of the fixed roller is fixed with a plurality of spherical brush heads.

[0012] The brush consists of a connecting roller, a fixed roller and a spherical brush head. The outer side of the connecting roller is fixed to the bearing by fastener bolts to ensure that the connecting roller can rotate stably and reduce friction and wear.

[0013] Preferably, the spherical brush heads are arranged in a circular array, and the ends of the spherical brush heads are of a "spherical" structure.

[0014] The spherical brush head can fit the surface of the heat sink due to its "spherical" structure, effectively removing oil and dust while avoiding damage to the surface of the heat sink. When the brush rotates, the spherical brush head contacts the surface of the heat sink and removes dirt and dust through friction.

[0015] Preferably, the transformer includes an oil tank, the oil tank is fixed on the upper side of the base, several groups of high-voltage bushings are fixed on the top of the oil tank, several groups of low-voltage bushings are fixed on the top of the oil tank, an oil pillow is fixed on the upper side of the oil tank, and a heat sink is fixed on the outside of the oil tank.

[0016] The transformer consists of an oil tank, a high-voltage bushing, a low-voltage bushing, an oil pillow and a heat sink. The oil tank is the main part of the transformer and is used to store transformer oil. The high-voltage bushing and the low-voltage bushing are used to connect the high-voltage circuit and the low-voltage circuit respectively. The oil pillow is used to maintain the stability of the oil in the tank and prevent oil level fluctuations caused by changes in oil temperature. The heat sink is used to dissipate the heat generated by the transformer during operation to ensure the normal operation of the transformer.

[0017] Preferably, the driving component includes a rotating motor, two groups of rotating motors are fixed on the lower side of the base, reciprocating screws are fixed in the output direction of the two groups of rotating motors, a limiting block is fixed on the top of the reciprocating screw, two sliding rods are fixed on the upper side of the base, the outer side of the rotating motor is threadedly connected to a frame, and the outer side of the sliding rod is slidably fitted with the frame.

[0018] After the rotary motor is started, it drives the reciprocating screw to perform rotational motion. Due to the rotation of the reciprocating screw, the rotation is converted into a linear reciprocating motion of the frame through the threaded connection. The slide bar provides a stable sliding track for the frame to ensure that it can move smoothly, and the limit block serves to limit the movement range of the frame to prevent it from exceeding the predetermined cleaning area. Therefore, with the linear reciprocating motion of the frame, the cleaning device fixed on one side of the frame also moves accordingly. In this way, the brush is not only rotating, but also performing up and down linear motion to clean the heat sink, forming a compound cleaning action. This compound action enables the brush to cover a larger cleaning area and improves the cleaning efficiency.

[0019] Compared with the prior art, the utility model provides a self-cleaning transformer, which has the following beneficial effects:

[0020] 1. The utility model controls the driving component to perform up and down reciprocating motion to drive the cleaning component to clean the heat sink, thereby realizing automatic cleaning of the heat sink. The operation is simple and convenient, and the user does not need to perform manual operation, which reduces the burden of manual maintenance and solves the problem of dust accumulation on the heat sink of the transformer.

[0021] 2. The brush of the utility model adopts a spherical brush head design, which can fit the surface of the heat sink, avoid the damage that may be caused by traditional rigid cleaning tools, improve the cleaning effect, protect the integrity of the heat sink, and extend the service life of the heat sink.

[0035] The cleaning assembly 43 includes a support 431, the support 431 is fixed on the inner side of the outer shell 41, a plurality of groups of bearings 432 are fixed on the upper side of the support 431, a plurality of groups of main gears 433 are arranged on the inner side of the support 431, a plurality of groups of main gears 433 are meshed with sub-gears 434, and brushes 435 are fixed on the inner sides of the bearings 432, the main gears 433 and the sub-gears 434.

[0036] A set of main gears 433 is fixed at the output end of the servo motor 42 .

[0037] As the servo motor 42 rotates, the main gear 433 also starts to rotate. Since the main gear 433 and multiple sets of sub-gears 434 arranged on the inner side of the support 431 are meshed together, the sub-gear 434 will also rotate accordingly. This gear transmission mechanism ensures that the multiple main gears 433 and sub-gears 434 can rotate synchronously, thereby driving the brush 435 fixed on their inner side to rotate and clean.

[0038] The brush 435 includes a connecting roller 4351 , and the inner sides of the bearing 432 , the main gear 433 , and the sub-gear 434 are all fixed with connecting rollers 4351 . A fixed roller 4352 is fixed to one side of the connecting roller 4351 , and a plurality of spherical brush heads 4353 are fixed to the outer side of the fixed roller 4352 .

[0039] The brush 435 is composed of a connecting roller 4351, a fixed roller 4352 and a spherical brush head 4353. The outer side of the connecting roller 4351 is fixed to the bearing 432 by fastener bolts to ensure that the connecting roller 4351 can rotate stably and reduce friction and wear.

[0040] The spherical brush heads 4353 are arranged in a circular array, and the ends of the spherical brush heads 4353 are of a "spherical" structure.

[0041] The spherical brush head 4353 can fit the surface of the heat sink 25 due to its "spherical" structure, effectively removing oil and dust while avoiding damage to the surface of the heat sink 25. When the brush 435 rotates, the spherical brush head 4353 contacts the surface of the heat sink 25 and removes dirt and dust through friction.

[0042] Embodiment 2

[0043] Based on the above embodiment 1, reference Figure 1 , Figure 2 , Figure 3 The transformer 2 includes an oil tank 21. The oil tank 21 is fixed on the upper side of the base 1. Several groups of high-voltage bushings 22 are fixed on the top of the oil tank 21. Several groups of low-voltage bushings 23 are fixed on the top of the oil tank 21. An oil pillow 24 is fixed on the upper side of the oil tank 21. A heat sink 25 is fixed on the outer side of the oil tank 21.

[0044] The transformer 2 includes an oil tank 21, a high-voltage bushing 22, a low-voltage bushing 23, an oil pillow 24 and a heat sink 25. The oil tank 21 is the main body of the transformer 2 and is used to store transformer oil. The high-voltage bushing 22 and the low-voltage bushing 23 are used to connect the high-voltage circuit and the low-voltage circuit respectively. The oil pillow 24 is used to maintain the stability of the oil in the oil tank 21 to prevent oil level fluctuations caused by changes in oil temperature. The heat sink 25 is used to dissipate the heat generated by the transformer 2 during operation to ensure the normal operation of the transformer 2.

[0045] The driving component 3 includes a rotating motor 31. Two groups of rotating motors 31 are fixed on the lower side of the base 1. Reciprocating screws 32 are fixed in the output direction of the two groups of rotating motors 31. A limiting block 33 is fixed on the top of the reciprocating screw 32. Two sliding rods 34 are fixed on the upper side of the base 1. The outer side of the rotating motor 31 is threadedly connected to a frame 35, and the outer side of the sliding rod 34 is slidably fitted with the frame 35.

[0046] After the rotating motor 31 is started, it drives the reciprocating screw 32 to rotate. Due to the rotation of the reciprocating screw 32, the rotation is converted into a linear reciprocating motion of the frame 35 through the threaded connection. The slide bar 34 provides a stable sliding track for the frame 35 to ensure that it can move smoothly, and the limit block 33 serves to limit the moving range of the frame 35 to prevent it from exceeding the predetermined cleaning area. Therefore, with the linear reciprocating motion of the frame 35, the cleaning device 4 fixed on one side of the frame 35 also moves accordingly. In this way, the brush 435 is not only rotating, but also performing an up and down linear motion to clean the heat sink 25, forming a compound cleaning action. This compound action enables the brush 435 to cover a larger cleaning area and improve the cleaning efficiency.

[0047] Working principle: Please refer to Figure 1-Figure 7As shown, first, when the self-cleaning system is started, the servo motor 42 starts to run, and the output end of the servo motor 42 fixed on one side of the housing 41 is connected to a group of main gears 433 on the cleaning assembly 43. As the servo motor 42 rotates, the main gears 433 also start to rotate. Since the main gears 433 and the multiple groups of sub-gears 434 arranged on the inner side of the support 431 are meshed together, the sub-gears 434 will also rotate accordingly. This gear transmission mechanism ensures that the multiple main gears 433 and sub-gears 434 can The brush 435 is composed of a connecting roller 4351, a fixed roller 4352 and a spherical brush head 4353. The outer side of the connecting roller 4351 is fixed to the bearing 432 by fastener bolts to ensure that the connecting roller 4351 can rotate stably and reduce friction and wear. The spherical brush head 4353 can fit the surface of the heat sink 25 due to its "spherical" structure, effectively remove oil and dust, and avoid damage to the surface of the heat sink 25. When the brush 435 rotates, the spherical brush head 4353 contacts the surface of the heat sink 25, and removes dirt and dust through friction. At the same time, the driving component 3 also starts to work. After the rotating motor 31 is started, it drives the reciprocating screw 32 to rotate. Due to the rotation of the reciprocating screw 32, it rotates through the threaded connection, and this rotational motion is converted into a linear reciprocating motion of the frame 35. The slide bar 34 provides a stable sliding track for the frame 35 to ensure that it can move smoothly, and the limit block 33 plays a role in limiting the movement range of the frame 35 to prevent it from exceeding the predetermined cleaning area. Therefore, with the linear reciprocating motion of the frame 35, the cleaning device 4 fixed on one side of the frame 35 also moves accordingly. In this way, the brush 435 is not only rotating, but also performing an up and down linear motion to clean the heat sink 25, forming a composite cleaning action. This composite action enables the brush 435 to cover a larger cleaning area and improve the cleaning efficiency. In addition, the transformer 2 is a prior art, and the utility model will not be described in detail.
