Description

Technical Field

[0001] The invention relates to the technical field of transformer oil heat exchangers, and in particular to an iron-aluminum alloy fence type transformer oil heat exchanger. Background Art

[0002] Transformers usually need to be cooled by oil. During the process of cooling the transformer, the oil absorbs heat and causes its own temperature to rise. In this case, a heat exchanger is needed to cool the transformer oil. The oil that has absorbed the heat of the transformer is injected into the heat exchanger for circulation, so that the heat exchanger increases the flow path of the oil, and the oil can increase the contact area with the air through the heat exchanger. At the same time, the heat exchanger absorbs the heat of the oil and dissipates it into the air, thereby realizing heat exchange, cooling the oil and discharging it for recycling to cool the transformer. However, traditional transformer oil heat exchangers still have problems in actual operation.

At the same time, the rotating plate 27 will push the push head 24 during the rotation process, so that the push head 24 pushes the push rod 23 to translate along the guide sleeve 21 in the direction close to the spring 22, and then the push rod 23 squeezes the spring 22 to store energy during the translation process. As the rubber sleeve 16 moves downward, the rubber sleeve 16 will drive the hammer head 28 to move to the outside of the transformer oil heat exchanger 1 The gap on the surface is formed, thereby releasing the resistance effect on the hammer head 28, and then the spring 22 uses the rebound force to push the push rod 23 to move in the direction away from the spring 22 along the guide sleeve 21, and then the push rod 23 pushes the push head 24 to move together, so that the push head 24 pushes the rotary plate 27 during the movement. At the same time, the rotary plate 27 will use the rebound force of the spring 22 and the gravity of the hammer head 28 to drive the hammer head 28 to rotate in the direction away from the guide sleeve 21 with the rotating rod 31 as the center, so that the hammer head 28 can be rotated out from between the multiple brushes 19 and knock onto the transformer oil heat exchanger 1. The vibration generated by the knocking can loosen or knock off the dirt and impurities on the surface of the transformer oil heat exchanger 1. As the rubber sleeve 16 moves downward, the hammer head 28 can be reciprocally resisted and released, and then the spring 22 is reciprocally squeezed, and the rebound force of the spring 22 is used to prompt the hammer head 28 to reciprocate and hammer the transformer oil heat exchanger 1.

[0046] When the push rod 23 is pushed by the rotary plate 27 and the spring 22 to reciprocate along the guide sleeve 21, the push rod 23 will drive the retaining ring 25 to move together, so that the retaining ring 25 drives the connecting block 33 to reciprocate together, and at the same time, the connecting block 33 will use external force to drive the arc edge plate 34 to reciprocate together, so that the arc edge plate 34 uses external force and the inclination angle of the inclined block 32 to push the cross plate 30 to reciprocate laterally during the reciprocating movement, so that the cross plate 30 can drive the brush 19 to bend and deform laterally reciprocatingly under the support of the rubber sleeve 16, thereby cleaning the outer surface of the transformer oil heat exchanger 1 laterally, so as to use vibration to cooperate with the brush 19 to clean the dust, impurities and dirt on the outer surface of the transformer oil heat exchanger 1, thereby improving the cleaning effect.

[0047] When the pull rope 15 is pulled and wound to the outside of the roller rod 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 to move upward together, and then the herringbone rope 37 uses external force to move along the perforation 40 toward the direction close to the spring 22, so that the herringbone rope 37 pulls the rotary plate 27 to rotate in the direction close to the guide sleeve 21 with the rotating rod 31 as the center, and then the rotary plate 27 lifts the hammer head 28, so that the hammer head 28 moves between the multiple brushes 19 to prevent the hammer head 28 from affecting the upward movement and storage of the rubber sleeve 16.

[0048] Working principle: transformer oil is connected to the solenoid valve 3 through the connecting pipe 2 and enters the transformer oil heat exchanger 1. The transformer oil heat exchanger 1 is used to make the oil flow and exchange heat with the air to achieve a cooling effect. The cooled transformer oil is discharged through the connecting pipe 2 and the solenoid valve 3. The staff can control the flow of oil through the solenoid valve 3 as needed, and then adjust the working state of the transformer oil heat exchanger 1. During the cleaning process, the solenoid valve 3 can control the flow of oil in and out of the heat exchanger to ensure the stable operation of the entire system.

[0049] The roller 8, the traction rope 20 and other components drive the rubber sleeve 16 to move between the multiple transformer oil heat exchangers 1, and drive the brush 19 to clean the surface of the heat exchanger. The traction rope 20 drives the rubber sleeve 16 through the rotation of the roller 8. The rubber sleeve 16 is embedded with the brush 19. The brush 19 horizontally cleans the surface of the transformer oil heat exchanger 1. The hammering part generates reciprocating vibrations through the rotary plate 27, the hammer head 28 and the spring 22. The hammer head 28 knocks the outer surface of the transformer oil heat exchanger 1 during the cleaning process. 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 safe.

[0050] The 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.

[0051] When the cleaning is completed, the rubber sleeve 16 will be gradually retracted into the receiving cover 12 by retracting the pull rope 15. The rubber sleeve 16, the brush 19 and related components are stored in the receiving cover 12 to prevent them from interfering with the operation of the transformer oil heat exchanger 1. The brush 19 and the rubber sleeve 16 can be stored in the receiving cover 12 after cleaning, which not only avoids the vertical extraction space required by the traditional cleaning method, but also effectively saves the installation space and makes the device more compact.

[0052] The automated cleaning system reduces the frequency and time of manual operations, and also reduces damage and maintenance costs caused by improper cleaning. The staff only needs to regularly maintain and inspect the equipment, which greatly improves the reliability and stability of the equipment.

[0053] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
