Description

Technical Field

[0001] This invention relates to the field of transformer technology, and in particular to a high-efficiency heat dissipation transformer. Background Technology

[0002] Transformers generate a large amount of heat during operation. If this heat cannot be dissipated effectively and in a timely manner, it will affect the transformer's performance and service life. High-efficiency heat-dissipating transformers refer to transformers that significantly improve heat dissipation efficiency through the use of advanced technology and design. High-efficiency heat-dissipating transformers employ various heat dissipation methods, including natural air cooling, forced air cooling, and liquid cooling.

[0003] In the existing technology, when installing transformers in a space-constrained site, in order to reduce space occupation, the transformer usually needs to be suspended and installed on the ceiling of the building. The transformer is usually composed of many components such as iron core and coil. When the transformer is running, the silicon steel sheets in the iron core will vibrate under the action of alternating magnetic flux. The change of current in the transformer winding will generate electromagnetic force, causing the winding to vibrate. Vibration may affect the stability of the suspended transformer during use and increase the frequency of maintenance of the transformer by the staff. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a high-efficiency heat dissipation transformer.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a high-efficiency heat-dissipating transformer, comprising a mounting bracket, a connecting frame fixed to the top of the mounting bracket, an iron core fixed to the connecting frame, and a coil fixed to the connecting frame and sleeved on the outside of the iron core. The mounting bracket is provided with a heat dissipation fan assembly for blowing air to dissipate heat from the coil. The heat dissipation fan assembly includes a mounting box fixed to the mounting bracket, a rotating shaft rotatably mounted between the inner walls on both sides of the mounting box, a fan plate fixed to the rotating shaft, and a motor fixed to the mounting box for driving the rotating shaft to rotate. An air outlet is provided at the position of the mounting box corresponding to the coil. The mounting box is provided with an adsorption mechanism for adsorbing the mounting box onto the transformer mounting surface by the drive of the motor during transformer installation.

[0006] By adopting the above technical solution, when installing a transformer in a space with limited space, during the process of workers lifting the transformer to the installation position using a lifting device, the adsorption mechanism must first be oriented towards the installation surface of the transformer (such as the wall at the top of the building). Then, driven by the motor, the mounting box can be firmly adsorbed onto the installation surface of the transformer. The transformer can be fixed by expansion screws. During the use of the transformer, the adsorption mechanism enhances the connection stability between the transformer and the installation surface, improves safety, and helps reduce the frequency of transformer maintenance.

[0007] Furthermore, the installation box is equipped with a horizontally arranged movable plate, and the adsorption mechanism includes multiple adsorption components. Each adsorption component includes a connecting rod fixed to the bottom of the movable plate, a suction cup fixed to the lower end of the connecting rod and located below the installation box, and a spring sleeved on the connecting rod and fixed between the bottom of the movable plate and the bottom wall of the installation box. The connecting rod passes through the bottom of the installation box and slides in fit. The adsorption mechanism also includes a control component used only for driving the movable plate to rise and fall when installing the transformer.

[0008] By adopting the above technical solution, after the lifting device raises the transformer to the installation position with the suction cups facing the transformer's installation surface, the operator needs to control the raising and lowering of the movable plate through the control component. This causes the movable plate to push the connecting rod, gradually compressing the spring. Under the action of the connecting rod, the suction cups are gradually pressed against the transformer's installation surface. The air inside the multiple suction cups is simultaneously expelled, creating a negative pressure, which firmly adheres the entire transformer to the transformer's installation surface. After the transformer is fixed with expansion screws, the multiple suction cups work together to enhance the fixing effect on the transformer. In addition, the suction cups are usually made of silicone material. The cooperation of multiple suction cups helps to reduce the vibration generated by the transformer during operation, and helps to reduce the frequency of transformer maintenance due to transformer vibration (when the transformer's vibration frequency is high, the expansion screws are more likely to loosen, and the frequency of inspection by the operator will increase).

[0009] Furthermore, the control component includes a control unit, which includes a first crossbar rotatably mounted on the inner wall of the mounting box and perpendicular to the rotation axis, a worm gear fixedly sleeved on the first crossbar, an active friction wheel fixed to the end of the first crossbar away from the inner wall of the mounting box, a movable plate disposed inside the mounting box and perpendicular to the movable plate, a horizontal plate fixed to the side wall of the movable plate near the rotation axis, a vertical rod rotatably mounted on the top of the horizontal plate, an intermediate friction wheel fixed to the upper end of the vertical rod, a vertical plate fixed to the top of the horizontal plate and located on the side of the vertical rod away from the movable plate, and a through-mounted friction wheel on the vertical plate. The control assembly includes a second horizontal bar rotatably connected to the vertical plate, a driven friction wheel fixed to one end of the second horizontal bar and engaging with and pressing against the intermediate friction wheel, and a cam fixed to the end of the second horizontal bar away from the driven friction wheel. The first horizontal bar is located above the movable plate, and the second horizontal bar is located near the edge of the cam. The edge of the cam abuts against the top of the movable plate. The control assembly also includes a transmission unit for driving the worm gear to rotate by a motor when installing the transformer, and a moving unit for controlling the movement of the movable plate so that the wheel surface of the intermediate friction wheel engages with and abuts against the wheel surface of the active friction wheel.

[0010] By adopting the above technical solution, when controlling the lifting and lowering of the movable plate, the operator first needs to control the movement of the movable plate through the moving unit so that the wheel surface of the intermediate friction wheel cooperates and abuts against the wheel surface of the active friction wheel. At this time, the motor is turned on, and the transmission unit can control the worm gear to rotate through the motor drive. This causes the first crossbar fixed to the worm gear, the active friction wheel fixed to the first crossbar, the intermediate friction wheel abutting against the active friction wheel, the vertical rod fixed to the intermediate friction wheel, the driven friction wheel abutting against the intermediate friction wheel, the second crossbar fixed to the driven friction wheel, and the cam fixed to the second crossbar to all rotate. Since the second crossbar is located near the edge of the cam, the edge of the cam away from the second crossbar gradually pushes the movable plate to move and compresses the spring until the suction cup at the end of the connecting rod presses and adheres to the mounting surface of the transformer, which is beneficial for the subsequent fixed installation of the bracket.

[0011] Furthermore, the transmission unit includes a main synchronous pulley fixedly sleeved on the central rod of the rotating shaft, a transmission rod rotatably mounted on the inner wall of the mounting box and parallel to the rotating shaft, a driven synchronous pulley fixedly sleeved on the transmission rod, a synchronous belt meshing with both the main and driven synchronous pulleys, and a worm fixed to one end of the transmission rod away from the inner wall of the mounting box and meshing with a worm gear. The transmission rod is located above the movable plate.

[0012] By adopting the above technical solution, after the motor works, it drives the main synchronous pulley to rotate, which causes the synchronous belt meshing with the main synchronous pulley, the driven synchronous pulley meshing with the synchronous belt, the transmission rod fixed to the driven synchronous pulley, the worm fixed to the end of the transmission rod, and the worm wheel meshing with the worm to rotate. This causes the cam to control the lifting and lowering of the movable plate, and finally causes the suction cup to gradually press and adhere to the transformer mounting surface.

[0013] Furthermore, the moving unit includes an electric push rod fixed to the inner wall of the mounting box and a guide rod fixed to the inner wall of the mounting box. The push rod end of the electric push rod is fixed to the side wall of the moving plate near the inner wall of the mounting box. The guide rod passes through the moving plate and is slidably engaged. The length direction of the guide rod is parallel to the length direction of the push rod of the electric push rod.

[0014] By adopting the above technical solution, before installing the transformer, the staff needs to adjust the electric push rod and make the push rod of the electric push rod pull the moving plate to move, so that the horizontal plate, vertical rod, intermediate friction wheel, vertical plate, second horizontal rod, driven friction wheel and cam move synchronously until the side of the intermediate friction wheel away from the driven friction wheel matches and abuts against the wheel surface of the active friction wheel. Then, stop adjusting the electric push rod and control the motor to run, so that the suction cup can be controlled to gradually press and adhere to the installation surface of the transformer.

[0015] Furthermore, a connecting rope is fixed on the side wall of the movable plate away from the inner wall of the mounting box. Through holes are provided at the top of the movable plate and the bottom of the mounting box for the connecting rope to pass through. The end of the connecting rope away from the movable plate is fixed to the suction cup. The number of connecting ropes is equal to the number of suction cups and their positions correspond one-to-one.

[0016] By adopting the above technical solution, when the staff adjusts the electric push rod and moves the moving plate away from the connecting rod, the moving plate can pull the suction cup through the connecting rope, thereby depressurizing the suction cup which is in a vacuum state. This helps the staff to quickly release the suction effect of the suction cup when disassembling the transformer, thus promoting the disassembly of the transformer.

[0017] Furthermore, the cam has a plurality of balls on its wheel surface, and the plurality of balls are evenly distributed about the wheel surface of the cam.

[0018] By adopting the above technical solution, the ball bearings reduce the relative friction between the cam and the moving plate during movement or rotation.

[0019] Furthermore, the distance between the center of the ball and the center of the cam is less than the radius of the cam.

[0020] By adopting the above technical solution, the stability of the ball bearings during use is guaranteed.

[0021] Furthermore, the cross-section of the fan plate is arc-shaped, and the fan plate has multiple fan plates that are evenly distributed about the axis of rotation.

[0022] By adopting the above technical solution, after the motor works and drives the fan plate to rotate, the air blown out by the fan blows towards the coil from the air outlet, which plays a good role in heat dissipation for the transformer.

[0023] Furthermore, a filter screen for blocking the air outlet is detachably connected to the mounting box.

[0024] By adopting the above technical solution, the filter screen plays a certain protective role against willow catkins, insects and other debris, ensuring the cleanliness of the inside of the installation box.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. The adsorption mechanism in this application enhances the connection stability between the transformer and the mounting surface, improves safety, and helps reduce the frequency of transformer maintenance;

[0027] 2. In this application, when the suction cups face the mounting surface of the transformer, the operator can control the lifting and lowering of the movable plate through the control component, thereby simultaneously controlling multiple suction cups to press and adhere to the mounting surface of the transformer. After the air inside the multiple suction cups is expelled, a negative pressure is formed, which firmly adheres the entire transformer to the mounting surface of the transformer, thus playing a good role in facilitating the fixing of the mounting bracket.

[0038] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] like Figure 1-9 As shown, this application discloses a high-efficiency heat-dissipating transformer, including a mounting bracket 1, a connecting frame 2 fixed to the top of the mounting bracket 1, an iron core 3 fixed to the connecting frame 2, and a coil 4 fixed to the connecting frame 2 and sleeved on the outside of the iron core 3 (the coil 4 in the figure is a high-voltage coil; the low-voltage coil, low-voltage output copper busbar, pad, high-voltage terminal, high-voltage connecting rod, high-voltage tap, high-voltage connecting piece, etc. of the transformer are all existing technologies of transformers, and this application does not make structural improvements to the above components, so they are not shown in the figure and need not be described in detail). The mounting bracket 1 is provided with a cooling fan assembly 5 for blowing air to dissipate heat from the coil 4. The cooling fan assembly 5 includes a mounting box 51 fixed on the mounting bracket 1, a rotating shaft 52 rotatably mounted between the inner walls on both sides of the mounting box 51, a fan plate 53 fixed on the rotating shaft 52, and a motor 54 fixed on the mounting box 51 for driving the rotating shaft 52 to rotate. An air outlet 511 is provided at the position corresponding to the coil 4 on the mounting box 51. The mounting box 51 is provided with an adsorption mechanism 6 for adsorbing the mounting box 51 onto the transformer mounting surface by driving the motor 54 when installing the transformer.

[0040] When installing a transformer in a confined space, during the process of lifting the transformer to the installation position using a lifting device, the adsorption mechanism 6 must first be oriented towards the installation surface of the transformer (such as the wall at the top of a building). Then, driven by the motor 54, the mounting box 51 can be firmly adsorbed onto the installation surface of the transformer. The transformer can then be fixed by expansion screws. During the use of the transformer, the adsorption mechanism 6 enhances the connection stability between the transformer and the installation surface, improves safety, and helps reduce the frequency of transformer maintenance.

[0041] Specifically: The mounting box 51 is equipped with a horizontally arranged movable plate 7. The adsorption mechanism 6 includes multiple adsorption components 61. Each adsorption component 61 includes a connecting rod 611 fixed to the bottom of the movable plate 7, a suction cup 612 fixed to the lower end of the connecting rod 611 and located below the mounting box 51 (the bottom of the suction cup 612 is lower than the bottom of the mounting bracket 1 before the transformer is installed), and a spring 613 sleeved on the connecting rod 611 and fixed between the bottom of the movable plate 7 and the inner bottom wall of the mounting box 51. The connecting rod 611 passes through the bottom of the mounting box 51 and slides in fit. The adsorption mechanism 6 also includes a control component 62 used only to drive the movable plate 7 to rise and fall when installing the transformer.

[0042] After the lifting device raises the transformer to the installation position with the suction cups 612 facing the transformer's mounting surface, the operator needs to control the movable plate 7 to rise and fall via the control component 62. This causes the movable plate 7 to push the connecting rod 611, gradually compressing the spring 613. Simultaneously, the air inside the multiple suction cups 612 is expelled, creating a negative pressure. Under the action of the connecting rod 611, the suction cups 612 gradually press and adhere to the transformer's mounting surface. Subsequently, the mounting bracket 1 can be fixed to the transformer's mounting surface using expansion screws. The multiple suction cups work together to enhance the fixing effect on the transformer. In addition, the suction cups are usually made of silicone material. The cooperation of multiple suction cups helps to reduce the vibration generated by the transformer's operation and reduces the frequency of transformer maintenance due to transformer vibration (when the transformer's vibration frequency is high, the expansion screws are more likely to loosen, and the frequency of inspection by the operator will increase).

[0043] Control component 62 includes control unit 621. Control unit 621 includes a first crossbar 6210 rotatably mounted on the inner wall of mounting box 51 and perpendicular to the rotation axis 52, a worm gear 6211 fixedly sleeved on the first crossbar 6210, an active friction wheel 6212 fixed to the end of the first crossbar 6210 away from the inner wall of mounting box 51, a movable plate 6213 disposed inside mounting box 51 and perpendicular to movable plate 7, a crossbar 6214 fixed to the side wall of movable plate 6213 near the rotation axis 52, a vertical bar 6215 rotatably mounted on the top of crossbar 6214, an intermediate friction wheel 6216 fixed to the upper end of vertical bar 6215, a vertical plate 6217 fixed to the top of crossbar 6214 and located on the side of vertical bar 6215 away from movable plate 6213, and a through-type disposed in vertical plate 6214. The control assembly 62 includes a second horizontal bar 6218 rotatably connected to the vertical plate 6217, a driven friction wheel 6219 fixed to one end of the second horizontal bar 6218 and mating with the intermediate friction wheel 6216, and a cam 6220 fixed to one end of the second horizontal bar 6218 away from the driven friction wheel 6219. The first horizontal bar 6210 is located above the movable plate 7, and the second horizontal bar 6218 is located near the edge of the cam 6220. The edge of the cam 6220 abuts against the top of the movable plate 7. The control assembly 62 also includes a transmission unit 622 for driving the worm gear 6211 to rotate via the motor 54 when installing the transformer, and a moving unit 623 for controlling the movement of the movable plate 6213 so that the wheel surface of the intermediate friction wheel 6216 mats with and abuts against the wheel surface of the active friction wheel 6212.

[0044] When controlling the lifting and lowering of the movable plate 7, the operator first needs to control the movement of the movable plate 6213 through the moving unit 623 so that the wheel surface of the intermediate friction wheel 6216 engages and abuts against the wheel surface of the active friction wheel 6212. At this time, the motor 54 is turned on, and the transmission unit 622 can control the worm gear 6211 to rotate through the drive of the motor 54. This causes the first crossbar 6210 fixed to the worm gear 6211, the active friction wheel 6212 fixed to the first crossbar 6210, the intermediate friction wheel 6216 abutting against the active friction wheel 6212, and the intermediate friction wheel 6216 fixed to the intermediate friction wheel 6216 to move. The vertical rod 6215, the driven friction wheel 6219 which abuts against the intermediate friction wheel 6216, the second horizontal rod 6218 which is fixed to the driven friction wheel 6219, and the cam 6220 which is fixed to the second horizontal rod 6218 all rotate. Since the second horizontal rod 6218 is located near the edge of the cam 6220, the edge of the cam 6220 away from the second horizontal rod 6218 gradually pushes the movable plate 7 to move and compresses the spring 613 until the suction cup 612 at the end of the connecting rod 611 presses and adheres to the mounting surface of the transformer, which is beneficial for the subsequent fixed installation of the bracket 1.

[0045] The transmission unit 622 includes a main synchronous pulley (not shown in the figure) fixedly sleeved on the central rod of the rotating shaft 52, a transmission rod 6221 rotatably mounted on the inner wall of the mounting box 51 and parallel to the rotating shaft 52, a driven synchronous pulley 6222 fixedly sleeved on the transmission rod 6221, a synchronous belt 6223 meshing with both the main synchronous pulley and the driven synchronous pulley 6222, and a worm 6224 fixed to one end of the transmission rod 6221 away from the inner wall of the mounting box 51 and meshing with the worm gear 6211. The transmission rod 6221 is located above the movable plate 7.

[0046] After the motor 54 starts working, it drives the main synchronous pulley to rotate, which causes the synchronous belt 6223 meshing with the main synchronous pulley, the driven synchronous pulley 6222 meshing with the synchronous belt 6223, the transmission rod 6221 fixed to the driven synchronous pulley 6222, the worm gear 6224 fixed to the end of the transmission rod 6221, and the worm wheel 6211 meshing with the worm gear 6224 to rotate. This causes the cam 6220 to control the lifting and lowering of the movable plate 7, which ultimately causes the suction cup 612 to gradually press and adhere to the transformer mounting surface.

[0047] The moving unit 623 includes an electric push rod 6231 fixed to the inner wall of the mounting box 51 and a guide rod 6232 fixed to the inner wall of the mounting box 51. The push rod end of the electric push rod 6231 is fixed to the side wall of the moving plate 6213 near the inner wall of the mounting box 51. The guide rod 6232 passes through the moving plate 6213 and is slidably engaged. The length direction of the guide rod 6232 is parallel to the length direction of the push rod of the electric push rod 6231.

[0048] To reduce the vibration generated during transformer operation, the operator needs to adjust the electric push rod 6231 so that the push rod of the electric push rod 6231 pulls the moving plate 6213 to move, so that the horizontal plate 6214, vertical rod 6215, intermediate friction wheel 6216, vertical plate 6217, second horizontal rod 6218, driven friction wheel 6219 and cam 6220 move synchronously until the side of the intermediate friction wheel 6216 away from the driven friction wheel 6219 mates with and abuts against the wheel surface of the driving friction wheel 6212. Then, stop adjusting the electric push rod 6231 and control the motor 54 to run, so that the suction cup 612 can be controlled to gradually press and adhere to the transformer mounting surface.

[0049] A connecting rope 8 is fixed on the side wall of the movable plate 6213 away from the inner wall of the mounting box 51. The top of the movable plate 7 and the bottom of the mounting box 51 are both provided with through holes for the connecting rope 8 to pass through (not shown in the figure). The end of the connecting rope 8 away from the movable plate 6213 is fixed to the suction cup 612. The number of connecting ropes 8 is equal to the number of suction cups 612 and their positions correspond one-to-one.

[0050] When disassembling the transformer later (such as when the transformer is damaged or replaced with a new model or with new functions), the staff first needs to adjust the electric push rod 6231 and move the moving plate 6213 away from the connecting rod 611. The moving plate 6213 can pull the suction cup 612 through the connecting rope 8, thereby depressurizing the suction cup 612 which is in a vacuum state. This helps the staff to quickly release the suction effect of the suction cup 612 when disassembling the transformer. Then, with the help of tools and by removing the expansion screws, the transformer can be disassembled.

[0051] To reduce the relative friction between the cam 6220 and the movable plate 7 during movement or rotation, a plurality of balls 9 are provided on the wheel surface of the cam 6220. The plurality of balls 9 are evenly distributed about the wheel surface of the cam 6220, and the distance between the center of the ball 9 and the center of the cam 6220 is less than the radius of the cam 6220.

[0052] In this embodiment, the cross-section of the fan plate 53 is arc-shaped, and the fan plate 53 has multiple fan plates evenly distributed about the axis of the rotation shaft 52. After the motor 54 operates and drives the fan plate 53 to rotate, the air blown by the fan is blown from the air outlet 511 to the coil 4, which plays a good role in heat dissipation for the transformer.

[0053] The mounting box 51 is detachably connected to a filter screen 10 for blocking the air outlet 511. The filter screen 10 provides a certain degree of protection against debris such as willow catkins and insects, ensuring the cleanliness of the inside of the mounting box 51.

[0054] Before installing the transformer, the workers first need to lift the transformer to the installation position with the lifting device facing the installation surface of the transformer (such as the wall at the top of the building). At this time, the workers need to adjust the electric push rod 6231 so that the push rod of the electric push rod 6231 pulls the moving plate 6213 to move, so that the horizontal plate 6214, vertical rod 6215, intermediate friction wheel 6216, vertical plate 6217, second horizontal rod 6218, driven friction wheel 6219 and cam 6220 move synchronously until the side of the intermediate friction wheel 6216 away from the driven friction wheel 6219 is engaged with the wheel surface of the driving friction wheel 6212 and pressed tightly. Then, stop adjusting the electric push rod 6231 and control the motor 54 to run. After the motor 54 starts working, it drives the main synchronous pulley to rotate, thereby causing the synchronous belt 6223 meshing with the main synchronous pulley, the driven synchronous pulley 6222 meshing with the synchronous belt 6223, the transmission rod 6221 fixed to the driven synchronous pulley 6222, the worm gear 6224 fixed to the end of the transmission rod 6221, and the worm wheel 6211 meshing with the worm gear 6224 to rotate. This causes the first crossbar 6210 fixed to the worm wheel 6211, the driving friction wheel 6212 fixed to the first crossbar 6210, the intermediate friction wheel 6216 abutting against the driving friction wheel 6212, and the intermediate friction wheel 6216 to rotate. The fixed vertical rod 6215, the driven friction wheel 6219 which abuts against the intermediate friction wheel 6216, the second horizontal rod 6218 which is fixed to the driven friction wheel 6219, and the cam 6220 which is fixed to the second horizontal rod 6218 all rotate. Since the second horizontal rod 6218 is located near the edge of the cam 6220, the edge of the cam 6220 away from the second horizontal rod 6218 gradually pushes the movable plate 7 to move and compresses the spring 613 until the suction cup 612 at the end of the connecting rod 611 presses and adheres to the mounting surface of the transformer, which is beneficial for the subsequent fixed installation of the bracket 1.

[0055] During normal transformer operation, the position of the suction cup 612 does not require adjustment. Therefore, after the mounting bracket 1 is fixed, the operator only needs to adjust the electric push rod 6231 and move the moving plate 6213 towards the side closer to the connecting rod 611 until the intermediate friction wheel 6216 is completely separated from the active friction wheel 6212. At this point, the motor 54 will start working and drive the main synchronous wheel, rotating shaft 52, and fan plate 53 to rotate. The fan plate 53 will blow air to cool the coil 4 through the air outlet 511. As can be seen from the above analysis, the main synchronous wheel can drive the active friction wheel 6212 to rotate. After the intermediate friction wheel 6216 is separated from the active friction wheel 6212, the cam 6220, moving plate 7, connecting rod 611, and suction cup 612 are all stationary. This reduces the possibility of rapid pressure release of the suction cup 612 during transformer operation and helps to enhance the stability of the transformer during operation.
