Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and more particularly to a dry-type transformer. Background Art

[0002] A dry-type transformer is a current and voltage regulating tool used to increase or decrease the voltage of the electric energy produced by power generation equipment, thereby helping technicians to adjust and convert the different power values ​​output by the power generation equipment, and transmit the regulated electric energy to various commercial and residential electricity lives, ensuring people's daily safe use of electricity.

[0003] However, when dry-type transformers are used in the actual northwest desert environment, there is a lot of sand and dust in the desert environment, and the shell of the dry-type transformer is a fixed shell. After the transformer shell is in contact with the desert air for a long time, the sand and dust will adhere to and accumulate on the surface of the transformer shell. Therefore, a layer of sand insulation will be formed at some positions of the transformer shell, resulting in the heat generated inside the transformer shell cannot be dissipated in time. In addition, due to the characteristics of the desert environment, the temperature is high during the day and low at night. If the fixed transformer shell is not dissipated in time during the day, the components inside the transformer shell will cause the wires to burn out, and the components will not work well. The service life of the dry-type transformer is reduced and the normal and safe use of the transformer is seriously affected. Summary of the invention

[0008] Furthermore, the interior of the transformer housing 1 is symmetrically provided with shock absorbing assemblies, and four of the shock absorbing assemblies are provided. The shock absorbing assemblies include an arc-shaped shock absorbing plate 1, and the outer surface of the arc-shaped shock absorbing plate 1 penetrates and is slidably connected to the inner wall on the left side of the transformer housing 1.

[0010] Furthermore, the inner ring wall of the transformer housing 2 is slidably connected with an arc-shaped shock-absorbing plate 2, the right side of the arc-shaped shock-absorbing plate 2 is fixedly connected with a spring 2, the right side of the spring 2 is fixedly connected with a hollow plate 2, the outer surface of the hollow plate 2 penetrates and is fixedly connected to the inner ring wall of the transformer housing 1, and the left side of the hollow plate 2 penetrates and is slidably engaged with the arc-shaped shock-absorbing plate 2.

[0011] Furthermore, a scraping and wiping assembly is provided on the top of the transformer housing one, and the scraping and wiping assembly includes a telescopic knife head, the bottom of the telescopic knife head penetrates through and is slidably connected to the top of the outer ring of the transformer housing one, the bottom of the telescopic knife head is fixedly connected to a spring three, the bottom of the spring three is fixedly connected to the transformer housing one, and the blade at the top of the telescopic knife head contacts the outer ring wall of the transformer housing two.

[0012] Furthermore, an annular liquid-absorbing sponge is passed through and fixedly connected to the inner annular wall of the telescopic cutter head, and a wiping surface of the annular liquid-absorbing sponge is in contact with the outer annular wall of the transformer housing 2.

[0013] Furthermore, a blowing assembly is provided inside the transformer housing 1, and the blowing assembly includes a fan, the top of the fan penetrates through and is fixedly connected to the outer surface of the rotating shaft, and an air leakage port is opened on the inner ring bottom wall of the transformer housing 1.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) This solution sets a lifting assembly, which can indirectly drive the transformer housing 2 to slide up and down close to the inner wall of the transformer housing 1 during the rotation of the screw rods 1 and 2, and adjust the size of the inner cavity space of the transformer housing 2 and the transformer housing 1. Therefore, in the high temperature environment of the desert during the day, the transformer housing 1 and the transformer housing 2 will increase the heat dissipation area by increasing the inner cavity space and accelerate the heat dissipation efficiency. In the low temperature environment of the desert at night, the transformer housing 1 and the transformer housing 2 will reduce the inner cavity space to shrink the heat dissipation area, reduce heat loss, and protect the components in the inner cavity of the transformer housing 1 and the transformer housing 2 from being damaged by low temperature.

[0016] (2) Under the action of the up and down moving force of the transformer housing 2, the trace dust on the surface of the transformer housing 1 and the transformer housing 2 can be shaken off and split for a second time, so as to avoid the situation that when the transformer is used in a dusty environment, the transformer housing 1 and the transformer housing 2 composed of the fixed housing can only provide a single protection effect, resulting in the transformer housing 1 and the transformer housing 2 being in contact with the dust in the desert air for a long time, and the dust will adhere to and accumulate on the outer surface of the fixed housing, so that the accumulated dust will form a heat insulation layer, so that the high temperature and vibration generated inside the fixed housing cannot be discharged in time, resulting in damage to the internal components, arc interference problems, and the problem of short service life of the transformer. The high efficiency of the transformer housing 1 and the transformer housing 2 in blocking dust pollutants is improved, and the effect of constant temperature use of the components in the transformer without damage is enhanced, thereby ensuring that the dry-type transformer can be used normally in a desert environment with a large temperature difference between day and night.

[0017] (3) By setting a shock-absorbing component, the present scheme can indirectly enable the arc-shaped shock-absorbing plate 1 and the arc-shaped shock-absorbing plate 2 to perform left and right clamping movements under the action of the continuous upward push of the transformer housing 2. Therefore, the clamping form formed by the arc-shaped shock-absorbing plate 1 and the arc-shaped shock-absorbing plate 2 can be closely attached to the surface of the transformer housing 2 during the rising process of the transformer housing 2, thereby avoiding that during the telescopic adjustment process of the transformer housing 2, due to the instability of the extension of the transformer housing 2, some larger sand particles in the desert air will be stuck in the telescopic part of the transformer housing 1 and the transformer housing 2, causing vibration and noise when the transformer housing 2 moves, causing the transformer housing 2 and the transformer housing 1 to wear and deform, and the transformer housing 2 and the transformer housing 1 to have poor protection effects, thereby improving the efficiency of the stable operation of the transformer, enhancing the damage-free shock and noise reduction of the transformer, and ensuring the safe and normal use of all components of the transformer.

[0018] (4) By setting up a scraping and wiping component, the present scheme can indirectly enable the retractable blade head and the annular water-absorbing sponge to be closely attached to the outer wall of the transformer housing 2 for scraping and wiping operations under the action of the continuous downward contraction force of the transformer housing 2, thereby preventing the transformer housing 2 from being exposed to the desert environment for a long time. Because the sand and dust pollution particles carried in the desert air accumulate and adhere to the outer wall of the transformer housing 2, after the transformer housing 2 is blown by the wind for a long time, these pollutants will condense into hard lumps, causing the outer wall of part of the transformer housing 2 to become stuck and worn after shrinkage, causing unnecessary safety accidents, thereby improving the effectiveness of the safe use of the transformer housing 2 and the transformer housing 1, enhancing the strength of unimpeded scraping and wiping of the transformer, and ensuring the normal use of the transformer when it is powered on.

[0019] (5) This solution provides a blowing assembly, and under the action of the continuous rotation force of the fan, the fan transformer housing inner cavity performs a rotating blowing and diffusion operation, thereby preventing the heat generated by the components in the transformer housing inner cavity one and the transformer housing second from being discharged in time after long-term use, causing the components to fuse and burn, resulting in poor transformer use effect. The cooling and heat dissipation efficiency of the components in the transformer housing one and the transformer housing two is improved, the service life of the transformer housing one and the transformer housing two without abnormal temperature is extended, and the safe and normal use of the transformer components is ensured.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0041] See also Figures 1 to 14A dry-type transformer comprises a joint support base 1, the top of the joint support base 1 is fixedly connected with a transformer housing 11, the top of the transformer housing 11 penetrates and is slidably connected with a transformer housing 2 12, the top of the transformer housing 2 12 is fixedly connected with a joint plate 13, and a lifting assembly 2 is arranged inside the transformer housing 11;

[0042] The lifting assembly 2 includes a driving motor 21, which is fixedly connected to the inner bottom wall of the transformer housing 11, and a screw rod 22 is fixedly connected to the output end of the driving motor 21. The outer surface of the screw rod 22 penetrates and is threadedly connected to the left bottom of the transformer housing 12, and a transmission wheel 24 is penetrated and fixedly connected to the bottom outer surface of the screw rod 22. The outer surface of the transmission wheel 24 is sleeved with a transmission belt 25, and the right end of the transmission belt 25 is sleeved with a two-way rotating wheel 26. The bottom outer surface of the two-way rotating wheel 26 is sleeved with a transmission belt 27, and the right end of the transmission belt 27 is sleeved with a transmission wheel 28. The inner ring wall of the transmission wheel 28 is penetrated and fixedly connected with a screw rod 23.

[0043] The inner ring wall of the bidirectional rotating wheel 26 is penetrated by and fixedly connected with a rotating shaft 29, the top of the rotating shaft 29 is rotatably connected to the inner wall of the transformer housing 11, the outer surface of the spiral rod 23 is penetrated by and threadedly connected to the right bottom of the transformer housing 12, the bottom of the spiral rod 23 is rotatably connected to the inner bottom wall of the transformer housing 11, and the side wall of the transformer housing 12 is penetrated by and fixedly connected with a scale plate 210.

[0044] In view of the fact that the transformer housing 11 and the transformer housing 2 12 in the prior art are a fixed housing, after the fixed housing is in contact with the desert air for a long time, sand and dust will adhere to and accumulate on the outer surface of the fixed housing, so that a layer of sand insulation layer will be formed at some positions of the fixed housing, resulting in the phenomenon that the heat generated inside the fixed housing cannot be dissipated in time, causing the wires of the components inside the fixed housing to melt and the use effect of the components to be poor. In the present application, a lifting component 2 is provided. When in use, power is first turned on to drive the output shaft of the driving motor 21 to rotate, drive the fixedly connected spiral rod 1 22 to rotate, and the rotation of the spiral rod 1 22 drives the threaded transformer housing 2 12 to move upward, so that the transformer The transformer housing 12 can slide upward closely against the inside of the transformer housing 11, and the inner cavity space between the transformer housing 12 and the transformer housing 11 will gradually increase during the upward sliding process. Therefore, in the high temperature environment of the desert during the day, the transformer housing 11 and the transformer housing 12 will increase the heat dissipation area by enlarging the inner cavity space, thereby accelerating the heat dissipation efficiency. At the same time, the upward force of the transformer housing 12 can also shake off and split the trace sand and dust on the surface of the transformer housing 11 and the transformer housing 2 12, thereby reducing the occurrence of sand and dust insulation, improving the efficiency of the transformer housing 11 and the transformer housing 2 12 in blocking dust pollutants, enhancing the effect of constant temperature use of various components in the transformer without damage, and ensuring the normal use of the dry-type transformer.

[0045] It should be noted that when the spiral rod 22 rotates, it will also drive the transmission wheel 24 to rotate, and the transmission wheel 24 drives the two-way rotating wheel 26 set on the right end of the transmission belt 25 to rotate, and then the bottom of the two-way rotating wheel 26 drives the transmission wheel 28 set on the right end of the transmission belt 27 to rotate, so that the transmission wheel 28 drives the spiral rod 23 to rotate, so that the rotation of the spiral rod 23 drives the right side of the threaded transformer housing 2 12 to move upward, so that the spiral rod 1 22 and the spiral rod 23 can rotate synchronously to drive the transformer housing 2 12 to move upward stably;

[0046] If the transformer housing 12 moves downward and shrinks, power is turned on to drive the output shaft of the driving motor 21 to rotate, drive the fixedly connected spiral rod 22 to rotate, and make the spiral rod 22 rotate to drive the threaded transformer housing 12 to move downward, so that the transformer housing 12 can slide downward close to the inside of the transformer housing 11, and the inner cavity space between the transformer housing 12 and the transformer housing 11 will gradually become smaller during the sliding process of the transformer housing 12. Therefore, in the low temperature environment of the desert at night, the transformer housing 11 and the transformer housing 2 12 will shrink the heat dissipation area by reducing the inner cavity space, reduce heat loss, and protect the components in the inner cavity of the transformer housing 11 and the transformer housing 2 12 from being damaged by low temperature. At the same time, the downward force of the transformer housing 12 can secondary shake off and split the trace sand and dust on the surface of the transformer housing 11 and the transformer housing 2 12, thereby ensuring that the dry-type transformer can be used normally in the desert environment with a large temperature difference between day and night.

[0047] This solution sets a lifting assembly 2, and during the rotation of the screw rod 1 22 and the screw rod 2 23, the transformer housing 2 12 can be indirectly driven to slide up and down close to the inner wall of the transformer housing 1 11, and the size of the inner cavity space of the transformer housing 2 12 and the transformer housing 1 11 can be adjusted. Therefore, in the high temperature environment of the desert during the day, the transformer housing 1 11 and the transformer housing 2 12 will increase the heat dissipation area by increasing the inner cavity space, thereby accelerating the heat dissipation efficiency. In the low temperature environment of the desert at night, the transformer housing 1 11 and the transformer housing 2 12 will reduce the inner cavity space to shrink the heat dissipation area, reduce heat loss, and protect the components in the inner cavity of the transformer housing 1 11 and the transformer housing 2 12 from being damaged by low temperature.

[0048] Furthermore, under the action of the up and down moving force of the transformer housing 12, the trace dust on the surface of the transformer housing 11 and the transformer housing 2 12 can be secondary shaken off and separated, so as to avoid the transformer being used in a dusty environment. Because the transformer housing 11 and the transformer housing 2 12 composed of the fixed housing can only perform a single protection effect, after the transformer housing 11 and the transformer housing 2 12 are in contact with the dust in the desert air for a long time, the dust will adhere to and accumulate on the outer surface of the fixed housing, so that the accumulated dust will form a heat insulation layer, so that the high temperature and vibration generated inside the fixed housing cannot be discharged in time, resulting in damage to the internal components, arc interference problems, and the problem of short service life of the transformer. The high efficiency of the transformer housing 11 and the transformer housing 2 12 in blocking dust pollutants is improved, and the effect of constant temperature use of various components in the transformer is enhanced without damage, thereby ensuring that the dry-type transformer can be used normally in a desert environment with a large temperature difference between day and night.

[0049] like Figures 7 to 9As shown, the interior of the transformer housing 11 is symmetrically provided with shock absorbing components 3, and four shock absorbing components 3 are provided, and the four shock absorbing components 3 are distributed in a ring shape;

[0050] The shock absorbing assembly 3 includes an arc-shaped shock absorbing plate 31 , and the outer surface of the arc-shaped shock absorbing plate 31 penetrates and is slidably connected to the inner wall of the left side of the transformer housing 11 .

[0051] The right side arc surface of the arc-shaped shock-absorbing plate 31 contacts the outer ring wall of the transformer housing 12, and the left side of the arc-shaped shock-absorbing plate 31 is fixedly connected with a spring 32, and the left end of the spring 32 is fixedly connected with a hollow plate 33. The outer surface of the hollow plate 33 penetrates and is fixedly connected with the outer ring wall of the transformer housing 11, and the right side of the hollow plate 33 penetrates and is slidably engaged with the arc-shaped shock-absorbing plate 31.

[0052] The inner ring wall of the transformer housing 12 is slidably connected with an arc-shaped shock-absorbing plate 34, the right side of the arc-shaped shock-absorbing plate 34 is fixedly connected with a spring 35, the right side of the spring 35 is fixedly connected with a hollow plate 36, the outer surface of the hollow plate 36 penetrates and is fixedly connected to the inner ring wall of the transformer housing 11, and the left side of the hollow plate 36 penetrates and is slidably engaged with the arc-shaped shock-absorbing plate 34.

[0053] By setting the shock absorbing component 3, when in use, under the action of the pressing force on the transformer housing 12, when the outer wall of the transformer housing 12 moves up to contact the arc surface of the arc-shaped shock absorbing plate 31, the transformer housing 12 can squeeze the arc-shaped shock absorbing plate 31 to move leftward, and the arc-shaped shock absorbing plate 31 squeezes the spring 32 to the left to perform a contraction and force storage operation, so that the spring 32 can form a reverse thrust force after being squeezed, and then the spring 32 can push the arc-shaped shock absorbing plate 31 to the right to be close to the outer wall of the transformer housing 12, thereby avoiding the transformer housing 12 During the rising process, due to the influence of the vibration force generated by sliding friction, the transformer housing 12 will shake when it rises, and some larger sand particles in the sand and dust in the desert environment will get stuck in the expansion and contraction parts of the transformer housing 11 and the transformer housing 12, causing the friction vibration generated by the rising of the transformer housing 12 to increase, causing the transformer housing 12 to be seriously worn and deformed when it rises, thereby improving the accuracy of the stable rising of the transformer housing 12, enhancing the strength of the transformer housing 12 without obstruction of the shock-absorbing protection components, and ensuring the normal use of the transformer housing 12 without shaking and lifting.

[0054] It should be noted that, while the arc-shaped damping plate 1 31 damps the rising transformer housing 2 12, the transformer housing 2 12 can also simultaneously closely adhere to and squeeze the arc-shaped damping plate 2 34 to move to the right, and the arc-shaped damping plate 2 34 squeezes the spring 2 35 to the right to perform elastic force storage operation, so that the spring 2 35 can form a reverse thrust storage force to the left, and the spring 2 35 pushes the arc-shaped damping plate 2 34 to the left and closely adhere to the inner wall of the transformer housing 2 12, so that the arc-shaped damping plate 1 31 and the arc-shaped damping plate 2 34 can form a two-way clamping shape, thereby offsetting the vibration phenomenon generated during the rising process of the transformer housing 2 12, and maintaining the normal and stable rising of the transformer housing 2 12;

[0055] In addition, micro-power is still generated during the stable rise of the transformer housing 12, so that the transformer housing 12 can still shake off some of the larger dry sand and dust attached to its surface when it rises, thereby ensuring the normal heat dissipation of the dry-type transformer.

[0056] By setting the shock absorbing component 3, the present scheme can indirectly enable the arc-shaped shock absorbing plate 1 31 and the arc-shaped shock absorbing plate 2 34 to perform left and right clamping movements under the action of the continuous upward pushing of the transformer housing 2 12. Therefore, the clamping form formed by the arc-shaped shock absorbing plate 1 31 and the arc-shaped shock absorbing plate 2 34 can be close to the surface of the transformer housing 2 12 during the rising process of the transformer housing 2 12, so as to avoid that during the telescopic adjustment process of the transformer housing 2 12, due to the instability of the extension of the transformer housing 2 12, some larger sand particles in the desert air will be stuck in the telescopic part of the transformer housing 1 1 and the transformer housing 2 12, causing vibration and sound when the transformer housing 2 12 moves, causing the transformer housing 2 12 and the transformer housing 1 11 to wear and deform, and the transformer housing 2 12 and the transformer housing 1 11 The protection effect of the transformer housing 12 and the transformer housing 11 is not good, thereby improving the efficiency of the stable operation of the transformer, enhancing the strength of the transformer without damage to the shock absorption and noise reduction, and ensuring the normal and safe use of various components of the transformer.

[0057] like Figures 10 to 12 As shown, a scraping and wiping component 4 is provided on the top of the transformer housing 11;

[0058] The scraping and wiping assembly 4 includes a telescopic blade head 41, the bottom of which penetrates through and is slidably connected to the top of the outer ring of the transformer housing 11, the bottom of the telescopic blade head 41 is fixedly connected to a spring three 43, the bottom of the spring three 43 is fixedly connected to the transformer housing 11, and the blade edge at the top of the telescopic blade head 41 contacts the outer ring wall of the transformer housing 2 12.

[0059] An annular liquid-absorbing sponge 42 is passed through and fixedly connected to the inner annular wall of the telescopic blade head 41 , and a wiping surface of the annular liquid-absorbing sponge 42 is in contact with the outer annular wall of the transformer housing 12 .

[0060] By setting up the scraping and wiping component 4, when working, after the extended transformer housing 12 has been used for a long time, the output shaft of the driving motor 21 can be powered on to rotate, and the transformer housing 12 can be indirectly driven to start to retract downward. At this time, the blade end of the telescopic blade head 41 can be close to the surface of the transformer housing 12 to scrape off the sand and dust, so as to avoid the outer ring wall of the transformer housing 12 being in contact with the desert environment air for a long time, causing the surface of the transformer housing 12 to condense hard sand and dust pollution blocks, resulting in the transformer housing 12 The contraction is blocked, causing friction scratches on the surface of the transformer housing 12, and the problem of sand and dust rust occurs, thereby improving the sensitivity of the transformer housing 12 to retract, and enhancing the strength of the telescopic blade head 41 to scrape off the sand and dust blocks of the transformer housing 12 without damage, and ensuring the normal use of the transformer housing 12;

[0061] At the same time, after the telescopic blade 41 completes the scraping of the transformer housing 12, the annular liquid-absorbing sponge 42 can be wiped closely against the water droplet surface on the outer wall of the transformer housing 12 under the action of the continuous downward force of the transformer housing 12, thereby avoiding that after the transformer housing 12 completes the scraping of dust and hard blocks, there are still traces of water droplets remaining at the parts where the hard blocks are adhered to the transformer housing 12, causing the water droplets to penetrate into the inner cavities of the transformer housing 12 and the transformer housing 1 11 after the transformer housing 12 shrinks, causing components to contact water vapor to generate current discharge, arc burning and other phenomena, resulting in the problem of low safety coefficient of transformer use, improving the effectiveness of the safe use of the transformer housing 12 and the transformer housing 11, and strengthening the effect of removing water droplets on the surface of the transformer housing 12 after scraping by the telescopic blade 41, so as to ensure the normal and safe use of the transformer.

[0062] By setting up a scraping and wiping component 4, the present scheme can indirectly enable the telescopic blade head 41 and the annular liquid-absorbing sponge 42 to perform scraping and wiping operations in close contact with the outer wall of the transformer housing 12 under the action of the continuous downward contraction force of the transformer housing 12, thereby preventing the transformer housing 12 from being exposed to the desert environment for a long time. Because the sand and dust pollution particles carried in the desert air gather and adhere to the outer wall of the transformer housing 12, after the transformer housing 12 is blown by the wind for a long time, these pollutants will condense into hard lumps, causing the outer wall of part of the transformer housing 12 to become stuck and worn after shrinkage, causing unnecessary safety accidents, thereby improving the effectiveness of the safe use of the transformer housing 12 and the transformer housing 11, enhancing the strength of unimpeded scraping and wiping of the transformer, and ensuring the normal use of the transformer when it is powered on.

[0063] like Fig.13 and Fig.14 As shown, a blowing assembly 5 is provided inside the transformer housing 11;

[0064] The blowing assembly 5 includes a fan 51 , the top of which penetrates through and is fixedly connected to the outer surface of the rotating shaft 29 , and an air leakage port 52 is formed on the inner ring bottom wall of the transformer housing 11 .

[0065] By setting the blowing assembly 5, when working, the two-way rotating wheel 26 can drive the rotating shaft 29 to rotate under the action of the continuous rotating force of the two-way rotating wheel 26, and the rotating shaft 29 can drive the fixedly connected fan 51 to rotate, so that the fan 51 can perform a rotating blowing operation, and at the same time, the fan 51 can guide the blowing force generated by the rotation to the inner cavity of the transformer housing 1 11 and the transformer housing 2 12 through the leakage port 52, so that the wind force can be integrated with the heat in the inner cavity, and the speed of heat dissipation is accelerated during the rising process of the transformer housing 2 12, so as to achieve the high temperature desert environment during the day. In the environment, the transformer housing 12 is adjusted to rise to increase the space. At the same time, the wind can quickly blow out the heat in the inner cavity, so as to avoid the heat emitted by the components in the inner cavity of the transformer housing 11 and the transformer housing 2 12 after long-term use. It is not discharged in time, causing the components to be wired and burned, resulting in poor transformer use. The efficiency of cooling and heat dissipation of each component in the inner cavity of the transformer housing 11 and the transformer housing 2 12 is improved, the service life of the transformer housing 11 and the transformer housing 2 12 without abnormal temperature is enhanced, and the safe use of each component of the transformer is guaranteed.

[0066] Method of use: When the present invention is in use, first install the joint support base 1, transformer housing 11, transformer housing 2 12 and joint plate 13 to the designated power connection position, then power is turned on to drive the output shaft of the driving motor 21 in the lifting assembly 2 to rotate, and then the lifting assembly 2 drives the transformer housing 2 12 and the transformer housing 1 11 to extend upward, and then the shock absorbing assembly 3 is driven to clamp and shock-absorb the transformer housing 2 12, and at the same time, the blowing assembly 5 is driven to blow and dissipate the heat in the inner cavity formed by the coupling of the transformer housing 11 and the transformer housing 2 12. After the use of the transformer housing 2 12 is completed, the output shaft of the driving motor 21 can be driven to rotate again, and the transformer housing 2 12 can be driven to start the retraction operation, and the scraping and wiping assembly 4 can be further driven to perform mobile scraping and mobile wiping operations on the outer wall of the transformer housing 2 12. When the scale plate 210 is retracted to be flush with the inner top wall of the transformer housing 11, the output shaft of the driving motor 21 stops rotating and the device stops running.

[0067] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
