Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a transformer for wind power generation. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core (magnetic core). Its main functions include: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.

[0003] According to a publicly disclosed transformer for wind power generation (publication number: CN217361294U), in the above application, a base is set under the transformer and movable wheels are installed so that it can be quickly moved and used in the field of wind power generation. At the same time, fixed plates and movable straight plates are installed on both sides of the base. The movable straight plates are used to eliminate the instability caused by the movable wheels to ensure the stable use of the transformer. Limiting columns are set at the top positions on both sides of the movable straight plates, and the limiting columns are used to rotate so that the movable straight plates can be rotated and stored. A bottom straight plate is set at the bottom of the movable straight plate, so that easy-to-adjust positioning marbles can be installed, and the positioning marbles are used to extend into the corresponding slots, thereby ensuring the stability of the movable straight plates after storage, so that the transformer can be quickly moved and transported.

[0004] After the above patent is installed and used, weeds and fallen leaves in the wild can be easily blown into the gaps between the heat sinks on the surface of the transformer by strong winds, which can easily cause the weeds and fallen leaves to get stuck between the heat sinks. The heat sinks on the surface of the transformer are the main heat dissipation devices of the transformer. Weeds and fallen leaves stuck in the gaps between the heat sinks will cause the contact area between the heat sink and the air to become smaller, which will cause the heat exchange efficiency between the heat sink and the air to decrease, making it impossible for the transformer to fully dissipate heat, affecting the normal operation of the transformer.

[0016] 2.

[0017] 3. The present invention can drive the driving gear to rotate on the outer wall of the convex plate through the rotation of the rotating rod in coordination with the brush, the convex plate and the gear ring. The rotation of the driving gear in coordination with the eccentric rod and the slot can drive the insertion rod to slide back and forth on the inner wall of the brush. The reciprocating sliding of the insertion rod will drive the lever to move back and forth on the outer wall of the bristles of the brush. At this time, the lever can be used to remove dust or impurities attached to the bristles, so that the brush can be kept clean, so that the brush can better clean the insulator.

[0040] A lever 103 is fixedly installed on the top of the insertion rod 101. The lever 103 is in an "L" shape and is located inside the bristles of the brush 811. When the insertion rod 101 slides back and forth on the inner wall of the brush 811, the lever 103 can be used to push off impurities or dust attached to the bristles of the brush 811, so that the brush 811 can be kept clean and the brush 811 can better clean the insulator 2.

[0041] When the present embodiment is working, the sliding frame 76 will push and pull the connecting rod 84 back and forth while moving up and down the outer wall of the heat sink 3, so that the connecting rod 84 pushes and pulls the cross bar 83 back and forth, so that the cross bar 83 drives the sliding rod 81 to slide back and forth on the top of the transformer body 1, and the sliding rod 81 will drive the rack 82 to move back and forth synchronously while sliding back and forth, and the driving gear 86 meshing with the rack 82 can drive the rotating drum 85 to rotate back and forth on the outer wall of the insulator 2 while reciprocating. During the rotation of the rotating drum 85, the sliding block 812 will slide on the inner wall of the bracket 87 and stretch the spring 813 due to the centrifugal force, and the sliding block 812 will push the push rod 814, so that the push rod 814 pushes the push plate 810, and the push plate 810 will drive the rotating rod 89 to rotate on the inner wall of the bracket 87, and the rotating rod 89 will drive the brush 811 to gradually move out of the through groove 88, so that the brush can be 811 is attached to the surface of the insulator 2. At the same time, as the rotating drum 85 rotates, the bracket 87 and the rotating rod 89 can drive the brush 811 to move in contact with the surface of the insulator 2. The brush 811 can be used to sweep away impurities on the surface of the insulator 2 to prevent the surface of the insulator 2 from being corroded by impurities and causing the insulation performance of the insulator 2 to decrease. When the rotating drum 85 stops rotating, the elasticity of the spring 813 can drive the slider 812 to slide and reset on the inner wall of the bracket 87. At this time, the slider 812 will pull the push rod 814, so that the push rod 814 pulls the push plate 810. At this time, the push plate 810 will drive the rotating rod 89 to rotate and reset on the inner wall of the bracket 87. At the same time, the rotating rod 89 will drive the brush 811 to enter the interior of the through groove 88. The through groove 88 can be used to store the brush 811, so that the brush 811 can be separated from the insulator 2 and will not interfere with the normal operation of the insulator 2.

[0042] The rotating drum 85 can cooperate with the transmission belt 93 to drive the rotating shaft 91 to rotate synchronously on the top of the transformer body 1 while rotating. The rubber rod 94 can drive the bell 95 to make a circular motion around the rotating shaft 91 while rotating. At this time, the sound of the bell 95 can be used to drive away the birds around the transformer body 1 to prevent the birds from staying on the transformer body 1, thereby preventing the bird droppings from dripping on the transformer body 1, and further preventing the transformer body 1 from being corroded by the bird droppings. At the same time, the prismatic block 92 can drive the reflector 97 to rotate synchronously during the rotation of the rotating shaft 91. The reflector 97 will repeatedly refract the sunlight while rotating. The rotating shaft 91 can drive the disc 98 to rotate synchronously while rotating. When the disc 98 drives the guide rod 99 to contact the annular inclined surface block 96 during the rotation, the guide rod 99 will be squeezed by the annular inclined surface block 96, so that the guide rod 99 pushes the disc 98 upward, thereby The disc 98 slides upward on the outer wall of the rotating shaft 91. At this time, the disc 98 pushes the connecting rod 910, so that the connecting rod 910 pushes the reflector 97, so that the reflector 97 can rotate upward on the outer wall of the prismatic block 92. When the disc 98 drives the guide rod 99 to gradually disengage from the annular inclined surface block 96 during the rotation, the guide rod 99 will gradually disengage from the extrusion of the annular inclined surface block 96. At this time, the disc 98 will slide downward on the outer wall of the rotating shaft 91 and reset under the action of its own gravity. At the same time, the disc 98 will pull the connecting rod 910 downward, so that the connecting rod 910 pulls the reflector 97 downward, so that the reflector 97 can rotate downward and reset on the outer wall of the prismatic block 92. The reflector 97 can be driven to rotate back and forth up and down on the outer wall of the prismatic block 92 through repeated rotation of the rotating shaft 91 in conjunction with the annular inclined surface block 96, the guide rod 99, the disc 98, and the connecting rod 910. The reflector 97 can be driven to rotate back and forth up and down on the outer wall of the prismatic block 92 through the up and down reciprocating rotation of the reflector 97. The sunlight refracted by the reflector 97 can swing back and forth up and down.

[0043] When the rotating rod 89 drives the brush 811 to rotate, the convex plate 104 will be driven to move synchronously. When the convex plate 104 moves, the driving gear 105 will be driven to move synchronously. When the driving gear 105 moves, the gear ring 107 meshing with it can be used to make the driving gear 105 rotate on the outer wall of the convex plate 104. When the driving gear 105 rotates, the eccentric rod 106 will be driven to reciprocate on the inner wall of the slot 102. At the same time, the eccentric rod 106 will push and pull the insertion rod 101 back and forth, and then the insertion rod 101 can be driven to slide back and forth on the inner wall of the brush 811. When the insertion rod 101 slides back and forth, it will drive the lever 103 to move back and forth inside the bristles of the brush 811. When the lever 103 moves back and forth inside the bristles, it can remove dust or impurities attached to the bristles.
