DETAILED DESCRIPTION
[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0028] The present invention provides a component of a power transformer radiator, such as Figures 1 to 7 As shown, it includes a heat sink assembly 1, and the middle parts of the top and bottom ends of the heat sink assembly 1 are fixedly installed with pipes 2 connected to the heat sink assembly 1. The heat sink assembly 1 is a fin-type radiator in the prior art, which is composed of a plurality of heat sinks arranged equidistantly. A circulation pipe 3 is provided on the side of the pipe 2 away from the heat sink assembly 1, and a connecting pipe 4 is rotatably installed on the side of the circulation pipe 3 close to the pipe 2, and the connecting pipe 4 is fixedly connected and connected to the middle part of the pipe 2. A ring plate 5 is fixedly installed on the top and bottom of the heat sink assembly 1, and a support frame 6 is rotatably installed on the outside of the ring plate 5. A first gear 7 is fixedly provided on the outside of the lower connecting pipe 4, and a first motor 9 is fixedly connected to the outside of the lower circulation pipe 3 through a support 8. The output shaft of the first motor 9 is fixedly connected to a second gear 10 meshing with the first gear 7. An adjustment component for controlling the rotation of the output shaft of the first motor 9 according to the wind direction is provided on the outside of the upper circulation pipe 3, and a cutting component for cutting off plant branches is provided on the outside of the heat sink assembly 1.
[0029] When in use, connect the circulation pipe 3 to the transformer, and fix the support frame 6 to the outside of the transformer. After the installation is completed, when the transformer is in use, the transformer oil flows back into the transformer through the upper circulation pipe 3, the connecting pipe 4, the pipeline 2, the heat sink assembly 1, the lower connecting pipe 4, and the circulation pipe 3. When the transformer oil passes through the heat sink assembly 1, it exchanges heat with the outside world to cool the transformer oil. The outside wind passes through the gaps between adjacent heat sinks of the heat sink assembly 1 to dissipate heat to the heat sink. When the outside wind direction changes, if the direction of the heat sink assembly 1 does not change accordingly, the changed wind will blow to the side of the heat sink of the heat sink assembly 1. Since the heat sinks in the heat sink assembly 1 are equidistantly arranged, the heat sink at the front will dissipate the heat at the rear. The heat sink is blocked, affecting the heat dissipation of the rear heat sink. Therefore, when the wind direction changes, the adjustment component drives the output shaft of the first motor 9 to rotate with the second gear 10, thereby driving the first gear 7 to rotate, and then driving the connecting pipe 4, the pipeline 2, and the heat sink assembly 1 to rotate, so that the angle of the heat sink assembly 1 is adjusted so that the side of the heat sink can face the wind, so that the wind can blow through the gap between adjacent heat sinks, ensuring better heat dissipation. After the adjustment is completed, if there are many branches in the environment where the transformer is located, the branches will extend into the adjusted heat sink assembly 1, affecting the heat dissipation. Therefore, after the adjustment is completed, the cutting component will cut off the branches extending between the heat sinks, so that these branches fall out of the heat sink assembly 1, so that they will not hinder heat dissipation.
[0030] like Figure 1As shown, the adjustment component includes a wind direction sensor 12 fixedly mounted on the top of the upper pipe 2 , and a controller 11 is provided on the outer side of the upper pipe 2 , and the controller 11 can control the first motor 9 .
[0031] The wind direction sensor 12 detects the change of wind direction and drives the output shaft of the first motor 9 to make corresponding rotation through the controller 11, so as to complete the adjustment of the heat sink assembly 1 so that the heat sink side of the heat sink assembly 1 can always face the wind.
[0032] like Figures 3 to 6 As shown, the cutting assembly includes a transverse plate 29, the number of which is six, and three transverse plates 29 are fixedly installed on both sides of the heat sink assembly 1, and cutters 13 are provided on both sides of the heat sink assembly 1. The opposite sides of the upper and lower transverse plates 29 on the same side are provided with slide grooves, and the middle part of the middle transverse plate 29 is provided with a slide opening, and the cutter 13 passes through the slide opening and both ends are located in the slide groove. The outside of the cutter 13 is provided with a driving assembly for driving its movement, and the outer side of the cutter 13 is in contact with the side of the heat sink assembly 1.
[0033] After the heat sink angle is adjusted once, the drive assembly drives the cutter 13 to move along the slide slot, so as to cut off the tree branches extending into the heat sink assembly 1 .
[0034] like Figures 3 to 6 As shown, the driving assembly includes a screw rod 14 rotatably installed in the slide groove, both ends of the cutter 13 are threadedly sleeved on the outside of the screw rod 14, one end of the screw rod 14 extends to the outside of the slide groove and is fixedly connected to the first sprocket 15, one end of the middle cross plate 29 is fixedly connected to the second motor 17 through a fixed plate, the output shaft of the second motor 17 is fixedly connected to the second sprocket 18, the second sprocket 18 and the first sprocket 15 are connected by a chain belt 16, and the controller 11 can control the second motor 17.
[0035] After completing the adjustment of the heat sink assembly 1, the controller 11 drives the second motor 17 to rotate its output shaft in the forward direction, driving the second sprocket 18 to rotate, and cooperates with the chain belt 16 to drive the first sprocket 15 to rotate, thereby driving the screw rod 14 to rotate in the forward direction, and then driving the cutter 13 to move along the slide groove to cut the branches. Then the controller 11 controls the second motor 17 to rotate its output shaft in the reverse direction, and vice versa to achieve the reversal of the screw rod 14, so as to drive the cutter 13 to reset.
[0036] like Figures 3 to 6As shown, a clapper board 19 is provided on the outer side of the upper and lower horizontal plates 29, and sliding rods 20 are slidably installed on both sides of the clapper board 19. One end of the sliding rod 20 is fixedly connected to the horizontal plate 29, and the end of the sliding rod 20 away from the horizontal plate 29 is fixedly connected to the limit plate 21. A spring 22 is sleeved on the outside of the sliding rod 20 and located between the limit plate 21 and the clapper board 19. A lifting component is provided on the outside of the clapper board 19 for driving it to move in a direction away from the horizontal plate 29.
[0037] When the screw rod 14 reverses and the cutter 13 moves along the slide groove to reset, the lifting assembly cooperates to lift the clapper board 19, so that the compression spring 22 deforms it to generate a force, and then the lifting assembly cancels the lifting of the clapper board 19, and the spring 22 releases the force to quickly reset the clapper board 19, so that it hits the cross plate 29 and generates vibration. The vibration is transmitted to the heat sink assembly 1 to make it vibrate, so that the branches stuck between adjacent heat sinks after being cut off are shaken off, so that these branches are more completely separated from the heat sink assembly 1.
[0038] like Figure 4 As shown, the lifting assembly includes a mounting frame 24 fixedly connected to the outside of the cutter 13, a rotating shaft 25 is rotatably installed inside the mounting frame 24, a long plate 27 is fixedly sleeved outside the rotating shaft 25, a torsion spring 26 is sleeved outside the rotating shaft 25, two ends of the torsion spring 26 are respectively fixedly connected to the rotating shaft 25 and the mounting frame 24, a protrusion 28 is provided on the side of the long plate 27 close to the chain belt 16, an inclined surface is provided on the outside of the protrusion 28, a vertical rod 23 matching the inclined surface is equidistantly fixedly installed on the outside of the clapper board 19, and the mounting frame 24 is closed on the side close to the vertical rod 23.
[0039] When the screw rod 14 rotates forward, the cutter 13 moves with the mounting frame 24, the rotating shaft 25, the long plate 27, and the protrusion 28. After the long plate 27 contacts the vertical rod 23, it deflects, and the rotating shaft 25 rotates to torsion spring 26 to torsionally deform it. When the long plate 27 is separated from the vertical rod 23, the torsion spring 26 resets and the rotating shaft 25 resets, so that the long plate 27 is reset. When the screw rod 14 reverses, the same principle applies. When the protrusion 28 contacts the vertical rod 23, at this time, since one side of the mounting frame 24 is closed, At this time, the long board 27 is in conflict with the mounting frame 24 and cannot rotate, and remains stationary. As the protrusion 28 moves, its inclined surface squeezes the vertical rod 23, causing it to move with the clapper 19 in a direction away from the horizontal board 29, and compresses the spring 22 to deform it. When the protrusion 28 separates from the vertical rod 23, the compressed spring 22 releases its force and causes the clapper 19 to quickly reset, causing it to hit the horizontal board 29 and vibrate it. Subsequently, the protrusion 28 is in conflict with and separated from multiple vertical rods 23, so that the horizontal board 29 can vibrate continuously.
[0040] A sealing ring is provided at the connection between the connecting pipe 4 and the flow pipe 3 .
[0041] This makes it possible to improve the airtightness between the connecting pipe 4 and the flow pipe 3 .
[0042] The present invention further provides a power transformer radiator, which includes a heat sink assembly 1 and the components of the power transformer radiator as described above, wherein the components of the power transformer radiator are arranged on the surface of the heat sink assembly 1 .
[0043] Working principle: When in use, connect the circulation pipe 3 to the transformer, and fix the support frame 6 to the outside of the transformer. After the installation is completed, when the transformer is in use, the transformer oil flows back to the transformer through the upper circulation pipe 3, the connecting pipe 4, the pipeline 2, the heat sink assembly 1, the lower connecting pipe 4, and the circulation pipe 3. When the transformer oil passes through the heat sink assembly 1, it exchanges heat with the outside world to cool the transformer oil. The outside wind passes through the gaps between adjacent heat sinks of the heat sink assembly 1 to dissipate heat to the heat sink. When the outside wind direction changes, if the direction of the heat sink assembly 1 does not change accordingly, the changed wind will blow to the side of the heat sink of the heat sink assembly 1. Since the heat sinks in the heat sink assembly 1 are equidistantly arranged, the heat sink located in the front at this time The heat sink at the rear is blocked, affecting the heat dissipation of the heat sink at the rear. Therefore, when the wind direction changes, the wind direction sensor 12 detects the change in wind direction and drives the output shaft of the first motor 9 to make a corresponding rotation through the controller 11, so that the second gear 10 is rotated, thereby driving the first gear 7 to rotate, and then the connecting pipe 4, the pipeline 2, and the heat sink assembly 1 are rotated, so that the angle of the heat sink assembly 1 is adjusted so that the side of the heat sink can face the wind, so that the wind can blow through the gap between adjacent heat sinks, ensuring better heat dissipation. After the adjustment is completed, if there are many branches in the environment where the transformer is located, the branches will extend into the adjusted heat sink assembly 1, affecting the heat dissipation. Therefore, after the adjustment is completed, the controller 11 drives the second motor 17 to output The output shaft rotates forward, driving the second sprocket 18 to rotate, and cooperates with the chain belt 16 to drive the first sprocket 15 to rotate, thereby driving the screw rod 14 to rotate forward, and then driving the cutter 13 to move along the slide groove to cut the branches. When the screw rod 14 rotates forward, the cutter 13 moves with the mounting frame 24, the rotating shaft 25, the long plate 27, and the protrusion 28. After the long plate 27 conflicts with the vertical rod 23, it deflects, and drives the rotating shaft 25 to rotate and twist the torsion spring 26 to torsionally deform it. When the long plate 27 is separated from the vertical rod 23, the torsion spring 26 resets and drives the rotating shaft 25 to reset, so that the long plate 27 is reset. By cutting off the branches, these branches fall out of the heat sink assembly 1 so that they will not hinder heat dissipation. Then the controller 11 controls the second motor 17 to reverse its output shaft The screw rod 14 is reversed, and the driving cutter 13 is reset. When the screw rod 14 is reversed, the same principle applies. When the protrusion 28 conflicts with the vertical rod 23, since one side of the mounting frame 24 is closed, the long board 27 conflicts with the mounting frame 24 and cannot rotate, and remains stationary. As the protrusion 28 moves, its inclined surface squeezes the vertical rod 23 to make it move with the clapper board 19 in the direction away from the horizontal plate 29, and the spring 22 is compressed to deform it. When the protrusion 28 is separated from the vertical rod 23, the compressed spring 22 releases the force to quickly reset the clapper board 19, so that the horizontal plate 29 is hit and vibrated. Subsequently, the protrusion 28 conflicts and separates with multiple vertical rods 23, so that the horizontal plate 29 can be continuously vibrated, so that the vibration is transmitted to the heat sink assembly 1.The branches stuck between adjacent heat sinks after being cut off are shaken off, so that these branches are more completely separated from the heat sink assembly 1.
[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
