Description

Technical Field

[0001] This invention relates to the field of transformer oil heat exchanger technology, and more specifically to an iron-aluminum alloy grid-type transformer oil heat exchanger. Background Technology

[0002] Transformers typically require oil for cooling. However, the oil absorbs heat during the cooling process, causing it to heat up. Therefore, a heat exchanger is needed to cool the transformer oil. This is achieved by injecting the oil, which has absorbed heat from the transformer, into the heat exchanger. This increases the oil's flow path and allows it to have a larger contact area with the air. Simultaneously, the heat exchanger absorbs heat from the oil and dissipates it into the air, thus achieving heat exchange. This process cools the oil, which is then discharged and recycled to cool the transformer. However, traditional transformer oil heat exchangers still have problems in practical operation.

[0003] For example, in actual operation, transformer oil heat exchangers need to be exposed to the outside for a long time, and dust, impurities and dirt will stick to their outer surfaces. It is difficult to clean the dust, impurities and dirt that stick to the outer surfaces of multiple transformer oil heat exchangers that are close to each other. Too much dust, impurities and dirt will affect the heat exchange effect. Summary of the Invention

[0004] This invention provides a method for using an iron-aluminum alloy grid-type transformer oil heat exchanger. It utilizes liftable brushes installed between multiple transformer oil heat exchangers. During the lifting and moving process, the brushes knock off impurities and dirt from the transformer oil heat exchangers and simultaneously clean the surface of the transformer oil heat exchangers, reducing the difficulty of cleaning.

Detailed Implementation

[0074] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0075] like Figures 1 to 12 As shown, an embodiment of the present invention provides a steel-aluminum alloy grid-type transformer oil heat exchanger 1, comprising: a transformer oil heat exchanger 1 and connecting pipes 2 fixed at both ends of the transformer oil heat exchanger 1, wherein there are multiple transformer oil heat exchangers 1, a solenoid valve 3 is connected to one end of the connecting pipe 2 near the transformer oil heat exchanger 1, and the solenoid valve 3 communicates with multiple transformer oil heat exchangers 1, and a flange pipe 4 is fixed to one end of the solenoid valve 3 away from the transformer oil heat exchanger 1, and further comprising:

[0076] A cleaning section is provided on the outside of multiple transformer oil heat exchangers 1 and extends between multiple transformer oil heat exchangers 1 to clean the transformer oil heat exchangers 1.

[0077] The bending section is installed on the transformer oil heat exchanger 1 and connected to the cleaning section, so as to save the space occupied by the bending section;

[0078] The hammering part is provided through the cleaning part and is located between multiple transformer oil heat exchangers 1 to clean the transformer oil heat exchangers 1 by hammering.

[0079] The cleaning section includes a pulling component and a cleaning component. The pulling component is located on the outside of the transformer oil heat exchanger 1, and the cleaning component is located between multiple transformer oil heat exchangers 1 and is connected to the pulling component.

[0080] The folding section includes a receiving component and a supporting component. The receiving component is installed on the transformer oil heat exchanger 1, and the supporting component is connected to the cleaning component.

[0081] The hammering part includes a guide member and a hammer member. The guide member passes through the folding member and the hammer member is rotatably connected to the folding member and contacts the guide member.

[0082] Specifically, a support plate 5 is symmetrically fixed at the bottom of the transformer oil heat exchanger 1, and a fixed plate 6 is fixed at the end of the support plate 5 away from the transformer oil heat exchanger 1. A fixing hole is opened through the inside of the fixed plate 6. The first motor 7 is fixed on the outside of the support plate 5, and the drive end rotates through the support plate 5. The rotating roller 8 is located between the fixed plate 6 and the transformer oil heat exchanger 1.

[0083] The fixed plate 6 provides support for the support plate 5, so that the support plate 5 can stably support the transformer oil heat exchanger 1. The transformer oil heat exchanger 1 can provide a flow channel for transformer oil and has uniform gaps on its surface. The transformer oil heat exchanger 1 can provide stable support for the connecting pipe 2 and the solenoid valve 3. The solenoid valve 3 and the connecting pipe 2 can provide a flow channel for oil, so that oil can enter and exit the transformer oil heat exchanger 1. The solenoid valve 3 can stably support the flange pipe 4.

[0084] In practical application, the following is an example: Workers can use fixing components to securely install the fixing plate 6 at the work site through the fixing holes, and connect the transformer oil pipeline to the flange pipe 4 and the transformer using the fixing components. This allows the transformer oil, having absorbed heat, to enter the solenoid valve 3 through the flange pipe 4. Workers can control the solenoid valve 3 to control the pipeline flow, allowing the transformer oil to flow through the solenoid valve 3 and connecting pipe 2 into the transformer oil heat exchanger 1. During this flow, the transformer oil utilizes the heat exchanger 1 to increase its contact area with air, thereby achieving heat exchange and cooling. The cooled transformer oil is then discharged through the connecting pipe 2 and solenoid valve 3 for use in cooling the transformer.

[0085] In a preferred embodiment of the present invention, the pulling member includes:

[0086] The rotating roller 8 is rotatably positioned below the transformer oil heat exchanger 1;

[0087] The first motor 7 is located at one end of the rotating roller 8, and its driving end is connected to one end of the rotating roller 8;

[0088] The traction rope 20 is multiple, one end of which is fixedly connected to the rotating roller 8 and wound around the outside of the rotating roller 8, and the other end extends to the space between multiple transformer oil heat exchangers 1.

[0089] The pulling component is located above the transformer oil heat exchanger 1.

[0090] Specifically, the support plate 5 can provide stable support for the first motor 7, the first motor 7 can support the rotating roller 8 with the drive end and drive the rotating roller 8 to rotate, the rotating roller 8 can provide winding space and support for the traction rope 20, and the traction rope 20 can use external force to pull the rubber sleeve 16 downward under the resistance of the transformer oil heat exchanger 1.

[0091] The pulling components include:

[0092] Roller 11 is rotatably mounted above transformer oil heat exchanger 1.

[0093] The second motor 10 is located at one end of the roller 11, and its drive end is connected to one end of the roller 11.

[0094] There are multiple main ropes 13, one end of which is fixed to the outside of the roller 11 and located above multiple transformer oil heat exchangers 1.

[0095] There are multiple connecting rods 14, and multiple connecting rods 14 are fixedly connected to the main rope 13.

[0096] Specifically, the transformer oil heat exchanger 1 can provide stable support for the connecting plate 17, the connecting plate 17 can make the transformer oil heat exchanger 1 more robust, and the connecting plate 17 can stably support the housing cover 12. The housing cover 12 can provide stable support for the support plate 9, the support plate 9 can provide rotational support for the roller 11, and the support plate 9 can provide stable support for the second motor 10. The second motor 10 can drive the roller 11 to rotate using the drive end. The roller 11 can provide winding and entanglement space for the main rope 13, the connecting rod 14 and the pull rope 15. The connecting rod 14 can provide support for the pull rope 15 under the support of the main rope 13, so that the main rope 13 can use external force to synchronously pull the pull rope 15 to move through the connecting rod 14.

[0097] Cleaning components include:

[0098] Multiple pull ropes 15 are provided, with one end of each pull rope 15 fixed to the connecting rod 14 and the other end extending between multiple transformer oil heat exchangers 1, and located above the other end of the traction rope 20.

[0099] The rubber sleeve 16 is disposed between multiple transformer oil heat exchangers 1 and is located outside the pull rope 15, and is fixedly connected to the other end of the pull rope 15.

[0100] Multiple brushes 19 are fixed to the outside of the rubber sleeve 16.

[0101] The horizontal plate 30 is fixedly connected to the brush 19.

[0102] Specifically, the rubber sleeve 16 is made of elastic rubber, and the pull rope 15 can provide support for the bottom of the rubber sleeve 16. The rubber sleeve 16 can stably support the brush 19. The brush 19 is elastic and can be deformed under the action of external force. It will rebound after the external force is removed. It can also provide support for the horizontal plate 30. The horizontal plate 30 can use external force to push the brush 19 to deform laterally.

[0103] In practical application, the operator can control the first motor 7 to rotate under the support of the fixed plate 6 and the support plate 5 according to the actual situation. The first motor 7 drives the rotating roller 8 to rotate together, and the rotating roller 8 uses the rotational power to wind and wrap the traction rope 20. The traction rope 20 uses the external force of winding to pull the rubber sleeve 16 downward under the resistance of the end of the transformer oil heat exchanger 1 near the fixed plate 6. The rubber sleeve 16 moves downward gradually from the position near the support rod 18 along the side of the multiple transformer oil heat exchangers 1 that are close to each other. At the same time, the rubber sleeve 16 will gradually straighten during the movement and drive the brush 19 to move downward together. The brush 19 will come into contact with the surface of the transformer oil heat exchanger 1 under the drive and support of the rubber sleeve 16, and the surface of the transformer oil heat exchanger 1 will be cleaned by the brush 19 during the movement.

[0104] At the same time, the rubber sleeve 16 will drive one end of the pull rope 15 to move downward together, so that the pull rope 15 uses external force to pull the main rope 13 through the connecting rod 14 under the resistance and support of the housing cover 12, so that the main rope 13 uses external force to pull the roller 11 to rotate clockwise.

[0105] In another preferred embodiment of the present invention, the receiving member includes:

[0106] The containment cover 12 is fixed on the transformer oil heat exchanger 1 and is located above the support rod 18;

[0107] The sleeve 16 is hollow inside and made of rubber.

[0108] The pull cord 15 moves through the rubber sleeve 16 and the containment cover 12.

[0109] Specifically, the connecting plate 17 can provide stable support for the housing cover 12. One end of the housing cover 12 is connected to the cover plate 38 through a fixing component. The housing cover 12 can provide moving space for the rubber sleeve 16 and the brush 19, and can provide a blocking function for the rubber sleeve 16, as well as a storage and deformation space for the rubber sleeve 16 and the brush 19.

[0110] Folding components include:

[0111] Multiple support rods 18 are fixed to the transformer oil heat exchanger 1 and movably pass through the rubber sleeve 16.

[0112] The pull rope 15 moves through the support rod 18 and the rubber sleeve 16;

[0113] The connecting plate 17 is fixed on multiple transformer oil heat exchangers 1 and is fixedly connected to the connecting pipe 2;

[0114] There are multiple partitions 39, which are fixed inside the housing 12 and are located above multiple transformer oil heat exchangers 1 and connected to the connecting plate 17.

[0115] Specifically, the connecting plate 17 provides stable support for the support rod 18, the support rod 18 provides a through channel for the pull rope 15, and provides a blocking support for the rubber sleeve 16, preventing the bottom end of the rubber sleeve 16 from completely entering the housing 12 and preventing the top end of the rubber sleeve 16 from completely entering between the multiple transformer oil heat exchangers 1. The housing 12 provides stable support for the partition 39, and the partition 39 provides a blocking effect for the rubber sleeve 16 and the brush 19, thus separating the space of the housing 12.

[0116] In practical application, the operator can control the second motor 10 to rotate counterclockwise under the support of the support plate 9, as needed. The second motor 10 drives the roller 11 to rotate counterclockwise under the support of the support plate 9, and uses this rotational power to wind up the main rope 13. This causes the main rope 13 to move along with the connecting rod 14 and wind up to the outside of the roller 11. Simultaneously, the connecting rod 14 pulls one end of the pull rope 15, gradually pulling the pull rope 15 to the outside of the roller 11. At the same time, the pull rope 15 uses external force to pull the rubber sleeve 16 upwards along the outside of the support rod 18. This will cause the brush 19 to move together, so that the rubber sleeve 16 and the brush 19 move together to the inside of the housing 12. As they move, the rubber sleeve 16 and the brush 19 come into contact with the inner wall of the housing 12. Under the resistance of the housing 12 and the pulling force applied by the pull rope 15, the rubber sleeve 16 deforms, causing the brush 19 to fold and be stored inside the housing 12 until the bottom inner wall of the rubber sleeve 16 is blocked by the support rod 18. This prevents the rubber sleeve 16 and the brush 19 from affecting the heat exchange operation of the transformer oil heat exchanger 1, and makes it easier to store the brush 19 and the rubber sleeve 16. Compared with the traditional method of pulling them out vertically, this method reduces the space occupied.

[0117] Furthermore, staff can disassemble the fixing components of the fixing cover 38 and remove the cover 38 as needed, thereby opening an opening from the position of the receiving cover 12 corresponding to the cover 38, allowing staff to maintain the stored brush 19 through the opening.

[0118] In a preferred embodiment of the present invention, the support member includes:

[0119] Multiple guide sleeves 21 are provided, and multiple guide sleeves 21 are disposed through the rubber sleeve 16 and located between multiple brushes 19;

[0120] Spring 22 is disposed on the inner side of guide sleeve 21;

[0121] Push rod 23 is fixed at both ends of spring 22 and passes through guide sleeve 21;

[0122] The push head 24 is fixed to the end of the push rod 23 away from the spring 22;

[0123] The auxiliary parts are located on the outside of the guide sleeve 21 and are connected to the rubber sleeve 16.

[0124] Specifically, the rubber sleeve 16 provides stable support for the guide sleeve 21, the brush 19 provides support for the horizontal plate 30, the rubber sleeve 16 can drive the guide sleeve 21 and the rotating plate 27 to move together during the movement, and the brush 19 can drive the horizontal plate 30 to move together. The guide sleeve 21 can provide space for the spring 22 and can provide a moving guide for the push rod 23. The push rod 23 can stably support the push head 24. The push head 24 has an arc and can use external force to push the rotating plate 27.

[0125] Auxiliary parts include:

[0126] The retaining ring 25 is fixed to the outside of the push rod 23 and is located at the end of the guide sleeve 21;

[0127] The groove 26 is formed on the outside of the rubber sleeve 16 and located below the guide sleeve 21;

[0128] The abutment rod 29 is fixed at one end to the outside of the guide sleeve 21, and the other end is fixedly connected to the inner wall of the rubber sleeve 16, and corresponds to the position of the groove 26.

[0129] The arc-edge plate 34 is positioned above the push head 24 and is connected to the retaining ring 25;

[0130] The inclined block 32 is located on the outside of the arc edge plate 34 and is fixedly connected to the horizontal plate 30.

[0131] Specifically, push rod 23 can stably support retaining ring 25, guide sleeve 21 can provide a blocking effect for retaining ring 25, thereby preventing push rod 23 from completely entering the inner side of guide sleeve 21. Guide sleeve 21 can stably support abutment rod 29. Abutment rod 29 can provide a blocking support for rubber sleeve 16 near groove 26 under the support of guide sleeve 21, preventing rubber sleeve 16 from deforming at the position of groove 26 when rotating plate 27 is pushed by external force to rotate towards guide sleeve 21. The side of retaining ring 25 away from guide sleeve 21 is fixed to connecting block 33, and connecting block 33 is fixedly connected to arc edge plate 34. Arc edge plate 34 can use external force and the tilt angle of inclined block 32 to push inclined block 32 to move laterally during reciprocating translation. Inclined block 32 can use external force to push horizontal plate 30 to move together. Horizontal plate 30 can use external force to push brush 19 to reciprocate and deform under the support of rubber sleeve 16.

[0132] The hammer components include:

[0133] Multiple rotating plates 27 are symmetrically arranged on the outside of the rubber sleeve 16, with one end extending into the groove 26 and rotatably connected to the rubber sleeve 16.

[0134] Hammer head 28 is fixed to the other end of rotary plate 27 and located among multiple brushes 19;

[0135] Rotary plate 27 is located at the end of push head 24 away from push rod 23;

[0136] The reset component is installed through the guide sleeve 21, push rod 23 and push head 24, and is connected to the pull rope 15 and the rotating plate 27.

[0137] Specifically, a rotating rod 31 is fixed at one end of the rotating plate 27 near the groove 26, and the rotating rod 31 is rotatably connected to the rubber sleeve 16. The rotating plate 27 can provide stable support for the hammer head 28, and the groove 26 can provide rotation space for the rotating plate 27 and the rotating rod 31. The outer side of the hammer head 28 has an arc, which can move up and down with the rubber sleeve 16 along with the rotating plate 27.

[0138] The reset component includes:

[0139] A perforation 40 is made to pass through the push rod 23 and the push head 24;

[0140] The herringbone rope 37 is provided through the through hole 40 and is located inside the spring 22. The end away from the spring 22 is connected to the rotating plate 27.

[0141] The connecting rope 36 is fixed to the end of the herringbone rope 37 away from the rotating plate 27 and passes through the spring 22 and the guide sleeve 21. The other end is connected to the pull rope 15.

[0142] Specifically, multiple connecting sleeves 35 are fixed to the outer side of the pull rope 15, and the connecting sleeves 35 are connected to the end of the connecting rope 36 away from the herringbone rope 37. The connecting rope 36 has redundant length, so as not to affect the rotation of the rotating plate 27. The through hole 40 can provide movement space for the herringbone rope 37. The pull rope 15 can pull the connecting rope 36 through the connecting sleeves 35 during the upward movement, so that the connecting rope 36 pulls the herringbone rope 37 together to pass through the guide sleeve 21 and move upward. Thus, the herringbone rope 37 can move along the through hole 40 and pull the rotating plate 27 to rotate around the rotating rod 31 in the direction closer to the guide sleeve 21.

[0143] In practical application, when the traction rope 20 pulls the rubber sleeve 16 downward, the rubber sleeve 16 will drive the guide sleeve 21, rotating rod 31, and rotating plate 27 to move downward together. As it moves downward, the rotating plate 27 will move with the rubber sleeve 16 and drive the hammer head 28 to move together, so that the hammer head 28 contacts the outer surface of the transformer oil heat exchanger 1. Under the resistance of the transformer oil heat exchanger 1, the hammer head 28 will push the rotating plate 27 to drive the rotating rod 31 to rotate in the inner side of the groove 26 with the rotating rod 31 as the center towards the guide sleeve 21. At the same time, the rotating plate 27 will push the push head 24 during the rotation, so that the push head 24 pushes the push rod 23 to translate along the guide sleeve 21 towards the spring 22. In this way, the push rod 23 will compress the spring 22 to store energy during the translation. As the rubber sleeve 16 moves downward, the rubber sleeve 16 will drive the hammer head 28 to move to the outer surface of the transformer oil heat exchanger 1. The gaps on the surface release the resistance of the hammer 28, allowing the spring 22 to use its rebound force to push the push rod 23 along the guide sleeve 21 to move away from the spring 22. This causes the push rod 23 to push the push head 24 to move together, and the push head 24 pushes the rotating plate 27 during the movement. At the same time, the rotating plate 27 uses the rebound force of the spring 22 and the gravity of the hammer 28 to drive the hammer 28 to rotate around the rotating rod 31 in a direction away from the guide sleeve 21. This allows the hammer 28 to rotate out from between the multiple brushes 19 and strike the transformer oil heat exchanger 1. The vibration generated by the strike loosens or knocks off the dirt and impurities on the surface of the transformer oil heat exchanger 1. As the rubber sleeve 16 moves downward, the hammer 28 can be repeatedly resisted and released, thus repeatedly squeezing the spring 22. The rebound force of the spring 22 causes the hammer 28 to repeatedly strike the transformer oil heat exchanger 1.

[0144] As the push rod 23 is pushed by the rotating plate 27 and the spring 22 to move back and forth along the guide sleeve 21, the push rod 23 will drive the retaining ring 25 to move together, causing the retaining ring 25 to drive the connecting block 33 to move back and forth. At the same time, the connecting block 33 will use external force to drive the arc edge plate 34 to move back and forth. During the reciprocating movement, the arc edge plate 34 will use external force and the tilt angle of the inclined block 32 to push the horizontal plate 30 to move laterally back and forth. This allows the horizontal plate 30 to drive the brush 19 to bend and deform laterally back and forth under the support of the rubber sleeve 16, thereby cleaning the outer surface of the transformer oil heat exchanger 1 laterally. In this way, the vibration combined with the brush 19 can clean the dust, impurities and dirt on the outer surface of the transformer oil heat exchanger 1, improving the cleaning effect.

[0145] During the process of the pull rope 15 being pulled and wound to the outside of the roller 11, the pull rope 15 will pull the connecting rope 36 through the connecting sleeve 35, so that the connecting rope 36 uses external force to pull the herringbone rope 37 upward, so that the connecting rope 36 passes through the guide sleeve 21 and pulls the herringbone rope 37 upward together, so that the herringbone rope 37 uses external force to move along the through hole 40 towards the direction of the spring 22, so that the herringbone rope 37 pulls the rotating plate 27 towards the direction of the guide sleeve 21 and rotates around the rotating rod 31, so that the rotating plate 27 lifts the hammer head 28, so that the hammer head 28 moves between the multiple brushes 19, preventing the hammer head 28 from affecting the upward movement and storage of the rubber sleeve 16.

[0146] Working principle: Transformer oil is connected to solenoid valve 3 via connecting pipe 2 and enters transformer oil heat exchanger 1. The heat exchanger 1 allows the oil to exchange heat with the air, achieving a cooling effect. The cooled transformer oil is then discharged through connecting pipe 2 and solenoid valve 3. Operators can control the oil flow via solenoid valve 3 as needed, thereby adjusting the operating status of transformer oil heat exchanger 1. During the cleaning process, solenoid valve 3 controls the flow of oil in and out of the heat exchanger, ensuring the stable operation of the entire system.

[0147] The rotating roller 8, traction rope 20, and other components drive the rubber sleeve 16 to move between multiple transformer oil heat exchangers 1, thereby driving the brush 19 to clean the surface of the heat exchangers. The traction rope 20 drives the rubber sleeve 16 through the rotation of the rotating roller 8. The brush 19 is embedded in the rubber sleeve 16 and performs lateral brushing on the surface of the transformer oil heat exchanger 1. The hammering part generates reciprocating vibration through the rotating plate 27, hammer head 28, and spring 22. During the cleaning process, the hammer head 28 strikes the outer surface of the transformer oil heat exchanger 1, and the vibration loosens or knocks off the surface dirt or impurities. The automatic cleaning of the transformer oil heat exchanger 1 avoids the high-intensity labor of manual cleaning, making the cleaning process more efficient and safer.

[0148] A clean surface of the transformer oil heat exchanger 1 can provide a larger heat exchange area, thereby improving the heat dissipation efficiency of the transformer, reducing the temperature rise of the transformer oil, and extending the service life of the transformer.

[0149] After cleaning, the rubber sleeve 16 will gradually retract into the housing 12 by pulling the rope 15. The rubber sleeve 16, brush 19 and related components are stored in the housing 12 to prevent them from interfering with the operation of the transformer oil heat exchanger 1. The brush 19 and rubber sleeve 16 can be stored in the housing 12 after cleaning, which not only avoids the vertical pulling space required by traditional cleaning methods, but also effectively saves installation space and makes the equipment more compact.

[0150] Automated cleaning systems reduce the frequency and time spent on manual operations, while also lowering damage and maintenance costs caused by improper cleaning. Staff only need to perform periodic maintenance and inspections, significantly improving the reliability and stability of the equipment.

[0151] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
