Description

Technical Field

[0001] This invention relates to the field of inductance adjustment technology, specifically to an adaptive heat dissipation and dust prevention transformer inductance adjustment device. Background Technology

[0002] As a core piece of equipment in the power system, the transformer's ability to adjust its inductance parameters (or equivalent turns ratio) directly affects the stability of output voltage, energy efficiency, and operational reliability.

[0003] Existing transformers typically employ fixed cooling fans, heat dissipation fins, and dust filters to address heat generation and dust issues. While these methods alleviate heat accumulation and dust intrusion to some extent, they have several drawbacks: 1. The cooling fan's fixed position, coupled with the fact that the actual current-carrying coil segment changes with inductance adjustment (or tap switching) during transformer operation, makes it difficult for a fixed fan to consistently target the primary heat-generating area, resulting in low cooling efficiency; 2. Dust filters are passive barriers and cannot actively remove dust already adhering to the coil surface. Especially in high humidity or high ionization environments, dust can firmly adhere to the coil, leading to decreased insulation performance and deteriorated heat dissipation; 3. There is a lack of linkage and control coupling between heat dissipation, dust removal, and inductance adjustment. Each system operates independently, resulting in structural redundancy and sluggish response.

[0004] Therefore, an adaptive heat dissipation and dust prevention transformer inductance adjustment device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive heat dissipation and dust prevention transformer inductance adjustment device, which has the advantage that the heat dissipation area and the dust removal area are always adjusted synchronously with the change of the effective coil length, thus solving the problems of low heat dissipation and dust removal efficiency and slow response.

Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figures 1 to 9 The present invention provides a technical solution: an adaptive heat dissipation and dust prevention transformer inductance adjustment device, including a base 2 for supporting and fixing an inductor coil 1, a heat dissipation fan 10 for dissipating heat from the inductor coil 1 on the base 2, and a moving contact 21 electrically connected to the inductor coil 1. The base 2 is provided with an inductance variable component for adjusting the relative position of the moving contact 21 and the inductor coil 1 to change the effective coil length. The base 2 is also provided with a heat response mechanism that adaptively adjusts the heat dissipation and dust prevention function according to the effective coil length.

[0046] The inductor coil 1 includes an integrally formed head end and tail end. The variable inductance component includes a co-position seat 19 that moves freely in the horizontal direction. The moving contact 21 is fixedly connected to the co-position seat 19. The effective coil length is between the head end and the moving contact 21.

[0047] The heat-relief mechanism includes a guide seat 3 that reciprocates along the laying direction of the inductor coil 1, a heat dissipation fan 10 is mounted on the guide seat 3, and the guide seat 3 is provided with a heat-driving structure that drives the heat dissipation fan 10 to rotate synchronously when its horizontal position changes.

[0048] The base 2 is provided with a fixed-distance structure that adjusts the horizontal movement stroke of the inductor coil 1 according to the effective coil length;

[0049] The base 2 is also provided with a speed-changing structure that adjusts the horizontal movement speed and heat dissipation force of the inductor coil 1 according to the effective coil length;

[0050] The guide seat 3 is provided with a pressure suction structure for removing dust adhering to the inductor coil 1.

[0051] An electric actuator for driving the horizontal movement of the co-position seat 19 is fixedly connected to the clamping frame 201, a guide rail is fixedly connected to the base 2, and a rail groove for the rail to slide through is opened on the co-position seat 19.

[0052] like Figure 1 and Figure 2 As shown, during the operation of the transformer, the effective coil length is between the first end of the inductor coil 1 and the moving contact 21. The effective coil length generates heat during operation. At the same time, the larger the effective coil length, the greater the impedance, which in turn generates more heat. Furthermore, since current flows through the effective coil, it is more likely to attract charged dust particles under the influence of the electromagnetic field, thus making it easier for dust to adhere to this area.

[0053] Therefore, during the actual operation of the inductor coil 1, the electric push rod can drive the co-position seat 19 and the moving contact 21 fixed thereon to move horizontally along the direction of the guide rail, and the direction of the guide rail is consistent with the direction of the inductor coil 1. This can change the relative position of the moving contact 21 and the inductor coil 1, thereby achieving the purpose of changing the effective coil length.

[0054] At the same time, the guide seat 3 carries the cooling fan 10 in a horizontal reciprocating motion. Driven by the fixed-distance structure, its stroke is kept basically consistent with the effective coil length, thereby ensuring that the effective heat dissipation area of ​​the cooling fan 10 is consistent with the effective coil length to achieve the best heat dissipation effect. Through the horizontal reciprocating motion of the cooling fan 10 and the guide seat 3, the heat dissipation area of ​​the cooling fan 10 can completely cover the effectively operating inductor coil 1, thereby achieving uniform heat dissipation and preventing overheating in some areas.

[0055] The guide seat 3 is also equipped with a suction structure for cleaning dust adhering to the inductor coil 1. The suction structure can move horizontally and reciprocally synchronously with the guide seat 3. In actual use, the effective coil length is prone to attracting dust particles during operation. Therefore, by setting the suction structure on the guide seat 3, the suction structure can concentrate on treating areas where dust easily accumulates, thereby improving cleaning efficiency.

[0056] It should be noted that in actual use, when the effective coil length increases, the total heat generation increases. In turn, the speed of the inductor coil 1 during horizontal reciprocating motion is increased by the speed-changing structure, and the speed of the cooling fan 10 is increased simultaneously, thereby achieving dynamic heat dissipation according to the change in the effective coil length.

[0057] In one preferred embodiment, the heating mechanism further includes a threaded rod 4 and a spline column 5 arranged parallel to the inductor coil 1. The spline column 5 rotates on the base 2 with a fixed axis. The horizontal sides of the base 2 are an integrally formed clamping frame portion 201 and a standing base portion 202, respectively.

[0058] The clamping frame 201 is provided with a power assembly that drives the threaded rod 4 and the spline column 5 to rotate synchronously.

[0059] The threaded rod 4 is threadedly connected to the guide seat 3. The guide seat 3 has an inner key I-shaped cylinder 6 that rotates on a fixed axis. The inner key I-shaped cylinder 6 is slidably sleeved on the spline column 5.

[0060] The support portion 202 is provided with a constant resistance assembly to ensure the rotational stability of the threaded rod 4.

[0061] like Figure 1 , Figure 2 and Figure 5 As shown, when driven by the power component, the threaded rod 4 and the spline column 5 can rotate synchronously. When the threaded rod 4 rotates, the inner keyed I-shaped cylinder 6 rotates on the guide seat 3 at a fixed axis. The inner keyed I-shaped cylinder 6 can only move along its laying direction under the restriction of the spline column 5. Thus, the rotation process of the threaded rod 4 can change the horizontal position of the guide seat 3. Under the impetus of the fixed distance structure, when the guide seat 3 moves to the set end position of the stroke on one side, the rotation direction of the threaded rod 4 will change, thereby changing the horizontal movement direction of the guide seat 3, and thus achieving the purpose of the guide seat 3 reciprocating within the set stroke.

[0062] Furthermore, the power assembly includes an active bevel gear 26 that is driven by a stepper motor and rotates freely in the vertical direction. The active bevel gear 26 meshes with a left bevel gear 27 and a right bevel gear 28. The left bevel gear 27 and the right bevel gear 28 are arranged opposite to each other and rotate on the clamping frame 201 with a fixed axis.

[0063] The left bevel gear 27 and the right bevel gear 28 are both sleeved on the threaded rod 4, and a single toothed ring 29 is coaxially fixed on the opposite surface of the left bevel gear 27 and the right bevel gear 28. The threaded rod 4 is fixedly sleeved with two sets of double toothed rings 30 at the corresponding positions. The double toothed rings 30 are always meshed with a set of single toothed rings 29. A coupling for transmitting the spline column 5 and the driving bevel gear 26 is fixedly connected on the clamping frame 201.

[0064] The resistance assembly includes a stop cylinder 23 fixedly sleeved on the threaded rod 4. A cylindrical cavity for sliding connection of the stop cylinder 23 is provided on the support portion 202. An integrally formed left stop ring groove 232 and a right stop ring groove 233 are provided on the stop cylinder 23. An integrally formed arcuate protrusion 231 is formed between the left stop ring groove 232 and the right stop ring groove 233. The support portion 202 is provided with multiple sets of bullet pressure pins 24 that slide in contact with the outer peripheral surface of the stop cylinder 23. The support portion 202 is provided with a receiving groove for sliding connection of the bullet pressure pins 24. A resistance spring 25 is provided in the receiving groove. The two ends of the resistance spring 25 are fixedly connected to the bullet pressure pins 24 and the support portion 202, respectively.

[0065] like Figure 2 , Figure 3 , Figure 4 and Figure 9 As shown, the stepper motor drives the active bevel gear 26 to rotate in the vertical direction, thereby driving the left bevel gear 27 and the right bevel gear 28 meshing with it to rotate synchronously. The left bevel gear 27 and the right bevel gear 28 are arranged opposite to each other, so the rotation directions of the left bevel gear 27 and the right bevel gear 28 are opposite. When the double toothed ring 30 meshes with the single toothed ring 29 on the left bevel gear 27, the bullet pressure pin 24 is in the right retaining ring groove 233. The threaded rod 4 follows the left bevel gear 27 to rotate forward. Subsequently, when the guide seat 3 moves to the end position of one side of the set stroke, under the restriction of the fixed distance structure, the threaded rod 4, the guide seat 3 and the components set on it can be caused to move a certain distance in the horizontal direction, thereby driving the arc protrusion 231 to pass the position of the bullet pressure pin 24, so that the bullet pressure pin 24 enters the left retaining ring groove 232.

[0066] At the same time, as the threaded rod 4 moves horizontally a certain distance, the double toothed ring 30 disengages from the single toothed ring 29 on the left bevel gear 27 and eventually meshes with the single toothed ring 29 fixed coaxially on the right bevel gear 28. After that, the threaded rod 4 rotates with the right bevel gear 28, thereby causing the guide seat 3 to move horizontally in the opposite direction. Therefore, by repeatedly changing the rotation direction of the threaded rod 4, the purpose of causing the guide seat 3 to reciprocate within the set stroke is achieved, so that the heat dissipation range of the cooling fan 10 is matched with the effective coil length of the inductor coil 1.

[0067] Meanwhile, a resistance spring 25 is provided on the support part 202 corresponding to the position of the bullet head pressure pin 24. Under the action of the resistance spring 25, when the guide seat 3 moves to the set stroke end position, the position switching action between the left and right resistance ring grooves 232 and the bullet head pressure pin 24 can be triggered, which can ensure the stability of the threaded rod 4 during horizontal movement.

[0068] Furthermore, the heat-driving structure includes a hollow worm 7 fixedly sleeved on the inner key-shaped cylinder 6, the hollow worm 7 being meshed with a worm wheel 8, and the worm wheel 8 rotating on the guide seat 3 on a fixed axis.

[0069] The guide seat 3 is fixedly connected to the speed-increasing gearbox 9, which includes an integrally formed input shaft and an output shaft. The input shaft and the output shaft are coaxially fixed with the worm gear 8 and the cooling fan 10, respectively.

[0070] like Figure 2 , Figure 5 , Figure 6 and Figure 8 As shown, driven by the coupling, the drive bevel gear 26 and the spline column 5 can rotate synchronously at a fixed speed ratio. When the spline column 5 rotates, it can drive the inner key I-shaped cylinder 6 sleeved on it to rotate on the guide seat 3. The inner key I-shaped cylinder 6 is fixedly sleeved with a hollow worm 7, and the hollow worm 7 is meshed with a worm wheel 8, so that when the horizontal position of the guide seat 3 changes, it can drive the worm wheel 8 to rotate synchronously horizontally.

[0071] Meanwhile, a speed-increasing gearbox 9 is provided between the worm gear 8 and the cooling fan 10. The speed-increasing gearbox 9 can cause the cooling fan 10 to rotate at a high speed when the worm gear 8 rotates at a slow speed, thereby ensuring its heat dissipation effect.

[0072] The speed change component can change the rotational speed of the drive bevel gear 26, thereby causing the threaded rod 4, worm gear 8 and cooling fan 10 to rotate more times per unit time. When the effective coil length increases, the rotational speed of the threaded rod 4 and cooling fan 10 is increased to improve heat dissipation efficiency and prevent heat buildup from causing equipment damage.

[0073] Based on the heat dissipation structure embodiment, the pressure suction structure includes two sets of return air cylinders 15 that are arranged opposite to each other and fixedly connected to the guide seat 3. A cross rod 13 is provided between the two sets of return air cylinders 15. An end plate 14 is fixedly connected to one side of the cross rod 13 facing the two sets of return air cylinders 15. The outer peripheral surface of the end plate 14 is slidably connected to the inner wall of the return air cylinder 15.

[0074] A bottom plate 11 is coaxially fixed on the worm gear 8. A pin 12 is fixedly connected to the side of the bottom plate 11 facing the cross rod 13. A straight groove is provided on the cross rod 13 for the pin 12 to slide.

[0075] A volute 16 is fixedly connected to the guide seat 3, an arc-scarring pipe 18 is fixedly connected to the volute 16, and the volute 16 is sleeved on the outer circumferential surface of the inductor coil 1. Multiple sets of suction nozzles 17 are fixedly connected to the volute 16, and the suction nozzles 17 and the arc-scarring pipe 18 are in gas communication.

[0076] Both sets of return air cylinders 15 include an integrally formed air inlet end and air outlet end. The air inlet end is connected to the arc-shaped pipe 18 for gas communication. An external exhaust pipe is fixedly connected to the base 2, and the air outlet end is connected to the external exhaust pipe for gas communication.

[0077] like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, when the worm gear 8 rotates, it can drive the bottom plate 11, which is fixed on the same axis, to rotate synchronously. The pin 12 fixedly connected to the bottom plate 11 is slidably connected to the cross rod 13 through a straight groove. Thus, when the worm gear 8 rotates, it can drive the cross rod 13 to make horizontal reciprocating motion between the two sets of return air cylinders 15.

[0078] Meanwhile, the end plate 14 fixed at the end of the cross rod 13 is slidably disposed inside the corresponding air return cylinder 15. During the reciprocating motion of the cross rod 13, the air near the inductor coil 1 is drawn through the air inlet, the arc-slit pipe 18 and multiple sets of suction nozzles 17. The negative pressure suction is used to separate the dust attached to the inductor coil 1 from it, or directly draw in the dusty air near the inductor coil 1. Subsequently, the dusty air is discharged to the outside natural air or the external dust collection box through the air outlet and the external exhaust pipe, thereby achieving the purpose of cleaning the surface of the inductor coil 1 to prevent dust accumulation.

[0079] Meanwhile, a set of one-way valves is fixedly installed at both the air inlet and air return ends of the return air cylinder 15, and the valve ports of the two sets of one-way valves are opposite, so that when the end plate 14 moves horizontally back and forth, the gas can only enter the return air cylinder 15 through the suction nozzle 17 and then be discharged through the external exhaust pipe, thereby restricting the flow direction of the gas.

[0080] Based on the pressure suction structure embodiment, the fixed distance structure includes a moving end transverse force spring 20 and a fixed end transverse force spring 22 sleeved on the spline column 5. The fixed end transverse force spring 22 is located at the first end of the inductor coil 1 and is fixedly connected to the stand part 202. The moving end transverse force spring 20 is fixedly connected to the co-position seat 19 and faces the guide seat 3.

[0081] The speed change structure includes a linear potentiometer electrically connected to the drive controller of the stepper motor. The mounting base 19 is connected to the slider integrally formed on the linear potentiometer. The voltage control signal output by the linear potentiometer changes accordingly as the distance between the moving end horizontal force spring 20 and the fixed end horizontal force spring 22 increases, so that the drive controller changes the speed of the stepper motor.

[0082] like Figure 1 , Figure 2 and Figure 5As shown, when the horizontal position of the co-position seat 19 is changed by the electric actuator, the horizontal position of the moving contact 21 and the moving end horizontal force spring 20 on it can be changed simultaneously. By changing the horizontal position of the moving contact 21, the effective coil length can be changed. At the same time, the position change of the co-position seat 19 can change the slider position of the linear positioner, thereby changing the rotational speed of the driving bevel gear 26.

[0083] Specifically, when the effective coil length increases, the rotational speeds of the drive bevel gear 26, the threaded rod 4, and the cooling fan 10 can all be increased, thereby adaptively increasing the heat dissipation intensity when the total heat generation increases, in order to cope with different working conditions and prevent overheating damage.

[0084] Meanwhile, the fixed-end horizontal force spring 22 is fixedly connected to the upright portion 202, and the change in the distance between the fixed-end horizontal force spring 22 and the moving-end horizontal force spring 20 is positively correlated with the change in the effective coil length. Specifically, when the guide seat 3 moves towards the fixed-end horizontal force spring 22, the guide seat 3 gradually approaches the beginning of the inductor coil 1. As the guide seat 3 gradually compresses the fixed-end horizontal force spring 22, it causes the fixed-end horizontal force spring 22 to undergo compression deformation. When the fixed-end horizontal force spring 22 undergoes compression deformation... This will apply a thrust to the guide seat 3 away from the upright portion 202, and this thrust will increase as the fixed end transverse force spring 22 continues to compress. Driven by this thrust, the guide seat 3 and the threaded rod 4 can move away from the upright portion 202, thereby causing the relative positions of the left and right blocking ring grooves 232 and the spring head blocking pin 24 to switch. As a result, the direction of the threaded rod 4 will change, and the guide seat 3 will then initially move towards the moving end transverse force spring 20.

[0085] When the guide seat 3 compresses the moving end horizontal force spring 20, causing the moving end horizontal force spring 20 to deform, it can then cause the relative positions of the left and right blocking ring grooves 232 and the bullet head blocking pin 24 to switch in the opposite direction. This causes the guide seat 3 to move towards the fixed end horizontal force spring 22. The position of the fixed end horizontal force spring 22 remains unchanged, while the position of the moving end horizontal force spring 20 changes with the position seat 19. Therefore, the horizontal stroke of the guide seat 3 is adapted to the actual coil length, thereby ensuring that the heat dissipation area and the dust removal area match the actual working conditions.

[0086] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
