Description

Technical Field

[0001] This invention relates to the field of transformer technology, and more specifically to a wind power generation transformer. Background Technology

[0002] Wind power generation refers to the process of converting the kinetic energy of wind into electrical energy. In the process of wind power generation, it is usually necessary to set up corresponding wind turbines and wind power transformers. The wind turbine converts wind energy into mechanical work, which drives the rotor to rotate, thereby outputting alternating current. The output alternating current undergoes voltage and current transformation under the action of the wind power transformer.

[0003] Transformers are an important component of power supply systems, and their proper operation determines the quality of power supply. Existing transformers generate a large amount of heat during long-term operation and have poor heat dissipation. Excessive transformer temperature will inevitably affect normal operation. Therefore, existing transformers have multiple heat dissipation fins fixed to their casing to improve heat dissipation.

[0004] However, the heat dissipation effect of this type of transformer is still limited. For high-power wind power transformers, which operate in high-temperature environments for a long time, the heat dissipation capacity of existing heat dissipation fins is insufficient to meet the high-efficiency heat dissipation requirements of the equipment. At the same time, wind power equipment is usually set up in open areas in the field, and dust in the environment is easy to continuously adhere to and accumulate on the surface of the heat dissipation fins, which will significantly reduce the heat exchange efficiency of the fins, further affecting the overall heat dissipation effect of the transformer, and thus adversely affecting the stable operation of the transformer. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by the present invention is that the heat dissipation effect of the existing heat dissipation methods on transformers is still limited. For high-power wind power transformers, which operate in high-temperature and other operating environments for a long time, the heat dissipation capacity of the existing heat dissipation fins is difficult to meet the high-efficiency heat dissipation requirements of the equipment. At the same time, wind power equipment is usually set up in open areas in the field, and dust in the environment is easy to continuously adhere to and accumulate on the surface of the heat dissipation fins, which will significantly reduce the heat exchange efficiency of the fins, further affecting the overall heat dissipation effect of the transformer, and thus adversely affecting the stable operation of the transformer.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a wind power generation transformer, comprising: The transformer casing has multiple vertical heat dissipation fins installed on it; A circulating heat exchange and heat dissipation mechanism includes: heat exchange pipes, connecting pipes, and a pump body; each heat dissipation fin is equipped with a heat exchange pipe arranged along the length of the heat dissipation fin, and adjacent heat exchange pipes are connected by connecting pipes to form a circulating heat dissipation loop; the pump body drives the liquid to circulate within the circulating heat dissipation loop; the cross-section of the circulating heat dissipation loop is rectangular to increase the area of ​​the circulating heat dissipation loop; and An air-cooled heat dissipation mechanism is provided between each of the two adjacent heat exchange pipes. The air-cooled heat dissipation mechanism includes a fan, a cleaning component, and a drive component. The fan is rotatably installed between the two adjacent heat exchange pipes, and the axis of the fan is oriented along the length direction of the heat exchange pipe. The cleaning component is slidably installed between the two adjacent heat exchange pipes along the length direction of the heat exchange pipe to clean the two adjacent heat exchange pipes. The drive component drives the fan to rotate and drives the cleaning component to slide back and forth.

[0007] Preferably, the drive assembly includes: a guide rod, a reciprocating screw, a nut seat, a connecting unit, a drive unit, and a transmission unit; the guide rod is fixed to the transformer housing, the reciprocating screw is rotatably mounted on the transformer housing, and both the guide rod and the reciprocating screw are arranged along the length direction of the heat exchange pipe; the nut seat is threadedly connected to the reciprocating screw; the cleaning assembly is fixed to the nut seat and slidably inserted into the guide rod; the fan is rotatably mounted on the guide rod, and the connecting unit connects the fan and the reciprocating screw to enable the fan and the reciprocating screw to rotate synchronously; the drive unit drives the reciprocating screw to rotate through the transmission unit.

[0008] Preferably, the transmission unit includes: a first bevel gear and a second bevel gear; the second bevel gear is coaxially fixed with the reciprocating screw, the first bevel gear is rotatably mounted on the heat exchange pipe, and the drive unit drives the first bevel gear to rotate.

[0009] Preferably, the drive unit includes: fan blades, a connecting shaft, and a guide plate; the connecting shaft is vertically rotatably mounted on the heat exchange pipe, and one end of the connecting shaft extends into the heat exchange pipe; the other end of the connecting shaft is coaxially fixed to the first bevel gear; one end of each of the multiple fan blades is arranged in a circular array with the axis of the connecting shaft as the center, and is fixed on the connecting shaft; and the fan blades are located inside the heat exchange pipe; the guide plate is inclinedly fixed inside the heat exchange pipe to guide the liquid inside the heat exchange pipe, thereby driving the multiple fan blades to rotate.

[0010] Preferably, there are two drive units and two first bevel gears facing each other, and each of the two first bevel gears meshes with one second bevel gear.

[0011] Preferably, the connecting unit includes: a first pulley, a second pulley, and a flat belt; the first pulley is coaxially fixed on the reciprocating lead screw, the second pulley is coaxially fixed on the fan, and the first pulley and the second pulley are connected by a flat belt.

[0012] Preferably, the connecting unit, driving unit, and transmission unit are located at the middle position along the length of the heat exchange pipe, and two reciprocating screws, nut seats, and cleaning components are respectively arranged opposite each other, with the two reciprocating screws being coaxially fixed.

[0013] Preferably, there are two guide rods, fans, and connecting units arranged opposite to each other on the reciprocating lead screw.

[0014] Preferably, it also includes a heat-conducting plate, one end of which is fixedly connected to the heat dissipation fins, and one end of which extends into the heat exchange pipe.

[0015] Preferably, the heat dissipation fins are open on the side closest to the transformer housing.

[0016] Compared with the prior art, the present invention has at least the following advantages: 1. In this invention, through the coordinated operation of circulating liquid cooling, forced air cooling, and automatic dust removal, the heat of the transformer is transferred to the heat dissipation fins through the shell. The circulating liquid efficiently absorbs heat in the heat exchange pipes and increases the heat dissipation area for rapid heat dissipation. The axial fan accelerates airflow to further enhance heat dissipation. At the same time, the cleaning component wipes and removes dust and impurities along the heat exchange pipes to prevent dust accumulation from affecting heat exchange efficiency. This significantly improves heat exchange efficiency and overall heat dissipation capacity, making it suitable for the high-temperature operating conditions of high-power wind power transformers. It effectively solves the problem of dust accumulation in the field environment and ensures the long-term stable operation of the transformer.

[0017] 2. In this invention, the pump body drives the liquid flow in the heat exchange pipe, and the inclined guide plate directs the liquid flow, so that the liquid continuously impacts multiple fan blades located in the heat exchange pipe, pushing the fan blades to rotate around the axis of the connecting shaft, thereby driving the connecting shaft to rotate synchronously. The connecting shaft then transmits the rotational power to the first bevel gear fixed on the same axis, providing stable and continuous driving power for the entire transmission unit. This drive unit uses the liquid flow to achieve self-drive, without the need for an additional motor power supply, is energy-saving and has a reliable structure. At the same time, it can work synchronously with the start and stop of the circulating heat dissipation circuit, ensuring that the driving action and the heat dissipation process are matched in real time.

[0018] 3. In this invention, one end of the heat-conducting plate is fixed to the heat dissipation fins, and the other end extends into the heat exchange pipe. This allows the heat on the heat dissipation fins to be directly and quickly transferred to the circulating liquid in the heat exchange pipe, significantly shortening the heat conduction path and improving the heat transfer efficiency from the heat dissipation fins to the circulating heat dissipation loop. Combined with the increased heat dissipation area of ​​the strip-shaped cross-section of the circulating heat dissipation loop, the liquid can absorb and dissipate heat more quickly, enhancing the overall heat dissipation effect of the circulating heat exchange mechanism, effectively reducing the operating temperature of the transformer, solving the problem of insufficient heat dissipation capacity of high-power wind power transformers, and ensuring stable operation of the transformer under high-temperature conditions.

[0019] 4. In this invention, the heat dissipation fins are open on the side closest to the transformer housing, which increases the contact area between the heat dissipation fins and the transformer housing, allowing the heat generated by the transformer housing to be conducted to each heat dissipation fin more quickly and evenly.

[0027] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0028] In this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0029] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] See Figures 1-5 The present invention provides an embodiment of a wind power transformer, comprising: a transformer housing 1, a circulating heat exchange and heat dissipation mechanism 2, and an air-cooled heat dissipation mechanism; the transformer housing 1 is equipped with multiple vertical heat dissipation fins 11; the circulating heat exchange and heat dissipation mechanism 2 includes: heat exchange pipes 21, connecting pipes 22, and a pump body; each heat dissipation fin 11 is equipped with a heat exchange pipe 21 arranged along the length of the heat dissipation fin 11, and adjacent heat exchange pipes 21 are connected by connecting pipes 22 to connect multiple heat exchange pipes 21 into a circulating heat dissipation loop; the pump body drives the liquid in the circulating heat dissipation loop to circulate; the circulating heat dissipation loop... The cross-section of the path is rectangular to increase the area of ​​the circulating heat dissipation loop; an air-cooled heat dissipation mechanism is provided between each two adjacent heat exchange pipes 21. The air-cooled heat dissipation mechanism includes: a fan 3, a cleaning component 4, and a drive component 5; the fan 3 is rotatably installed between two adjacent heat exchange pipes 21, and the axis of the fan 3 is oriented towards the length direction of the heat exchange pipe 21; the cleaning component 4 is slidably installed between two adjacent heat exchange pipes 21 along the length direction of the heat exchange pipe 21 to clean the two adjacent heat exchange pipes 21; the drive component 5 drives the fan 3 to rotate and drives the cleaning component 4 to slide back and forth.

[0031] In practice, the heat generated by the transformer is transferred to the transformer casing 1, and then conducted to multiple vertical heat dissipation fins 11. The pump body starts to drive the liquid circulation in the cooling loop. The liquid flows through the heat exchange pipes 21 arranged along the length of each heat dissipation fin 11, fully absorbing the heat on the heat dissipation fins 11. Adjacent heat exchange pipes 21 are connected by connecting pipes 22 to form a complete circulation loop. The strip-shaped cross-section of the circulation cooling loop increases the heat dissipation area, allowing the absorbed heat to be quickly dissipated by itself, greatly improving the heat exchange efficiency between the liquid and the heat dissipation fins 11, and quickly removing the heat. At the same time, the drive component 5 synchronously drives the fan 3 to rotate and the cleaning component 4 to reciprocate along the length of the heat exchange pipes 21. The fan 3 slides with its axis oriented along the length of the heat exchange pipe 21. When it rotates, it generates airflow along the length of the heat exchange pipe 21, accelerating the airflow on the surface of the heat exchange pipe 21 and further enhancing the heat dissipation effect. This helps the liquid quickly dissipate the absorbed heat. During the reciprocating sliding process, the cleaning component 4 wipes and cleans the surfaces of the two adjacent heat exchange pipes 21, promptly removing attached dust and impurities. This prevents dust accumulation from reducing the heat exchange efficiency of the heat exchange pipe 21, ensuring that the circulating heat exchange mechanism 2 and the air-cooled heat dissipation mechanism work together. This significantly improves the overall heat dissipation capacity of the wind power transformer, adapts to the high-temperature operating conditions of high-power transformers, and solves the problem of dust accumulation affecting heat dissipation in the field environment, ensuring the long-term stable operation of the transformer.

[0032] Furthermore, the cleaning component 4 includes a brush body 41 and bristles 42, with one end of the bristles 42 mounted on the brush body 41, and bristles 42 mounted on all four sides of the brush body 41.

[0033] See Figures 1-5 In other embodiments, the drive assembly 5 includes: a guide rod 51, a reciprocating screw 52, ​​a nut seat 53, a connecting unit 6, a drive unit 7, and a transmission unit 8; the guide rod 51 is fixed to the transformer housing 1, the reciprocating screw 52 is rotatably mounted on the transformer housing 1, and both the guide rod 51 and the reciprocating screw 52 are arranged along the length direction of the heat exchange pipe 21; the nut seat 53 is threadedly connected to the reciprocating screw 52; the cleaning assembly 4 is fixed to the nut seat 53 and slidably inserted into the guide rod 51; the fan 3 is rotatably mounted on the guide rod 51, and the connecting unit 6 connects the fan 3 and the reciprocating screw 52 so that the fan 3 and the reciprocating screw 52 rotate synchronously; the drive unit 7 drives the reciprocating screw 52 to rotate through the transmission unit 8.

[0034] In practice, the drive unit 7 drives the reciprocating screw 52 to rotate via the transmission unit 8. The reciprocating screw 52 synchronously drives the fan 3 to rotate via the connecting unit 6. The rotation of the fan 3 generates airflow along the length of the heat exchange pipe 21. On the one hand, this accelerates the heat dissipation speed of the heat exchange pipe 21 and the circulating heat dissipation loop, allowing the circulating heat dissipation loop to quickly dissipate heat by relying on its increased heat dissipation area due to its strip-shaped cross-section. On the other hand, the airflow can directly blow away the dust on the surface of the heat exchange pipe 21 and the dust cleaned by the cleaning component 4, promptly blowing the dust away from the area of ​​the heat exchange pipe 21 and preventing secondary adhesion and accumulation of dust. At the same time, the rotation of the reciprocating screw 52 drives the nut seat 53 to make a stable linear reciprocating motion along the guide rod 51. The nut seat 53 drives the cleaning component 4 to move synchronously along the guide rod 51. The heat exchange pipe 21 slides back and forth along its length to continuously wipe and clean the dust adhering to its surface. The guide rod 51 guides and limits the cleaning component 4 and the nut seat 53 to prevent deviation or jamming during the reciprocating motion, ensuring that the cleaning component 4 and the heat exchange pipe 21 are always in close contact. This allows the drive unit 7 to simultaneously drive the fan 3 for air cooling, dust blowing, and automatic dust cleaning of the cleaning component 4. The structure is compact and the transmission is efficient, which completely solves the problem of dust accumulation reducing heat dissipation efficiency in the field environment. It further improves the synergistic heat dissipation effect of the circulating heat exchange heat dissipation mechanism 2 and the air cooling heat dissipation mechanism, meets the high-efficiency heat dissipation requirements of high-power wind power transformers, and ensures the long-term stable operation of the transformer under high-temperature conditions in the field.

[0035] See Figures 1-5 In other embodiments, the transmission unit 8 includes a first bevel gear 81 and a second bevel gear 82; the second bevel gear 82 is coaxially fixed with the reciprocating screw 52, ​​and the first bevel gear 81 is rotatably mounted on the heat exchange pipe 21, and the drive unit 7 drives the first bevel gear 81 to rotate. In specific implementation, the drive unit 7 drives the first bevel gear 81 to rotate. Since the first bevel gear 81 and the second bevel gear 82 mesh with each other, the rotation of the first bevel gear 81 drives the second bevel gear 82 to rotate synchronously. The second bevel gear 82 is coaxially fixed with the reciprocating screw 52, ​​thereby driving the reciprocating screw 52 to rotate. The meshing transmission structure of the first bevel gear 81 and the second bevel gear 82 is compact, the transmission is smooth and the transmission efficiency is high, which can realize the precise transmission of power of the drive unit 7.

[0036] See Figures 1-5 In other embodiments, the drive unit 7 includes: fan blades 71, a connecting shaft 72, and a guide plate 73; the connecting shaft 72 is vertically rotatably mounted on the heat exchange pipe 21, and one end of the connecting shaft 72 extends into the heat exchange pipe 21; the other end of the connecting shaft 72 is coaxially fixed with the first bevel gear 81; one end of a plurality of fan blades 71 is arranged in a circular array with the axis of the connecting shaft 72 as the center, and is fixed on the connecting shaft 72; and the fan blades 71 are located inside the heat exchange pipe 21; the guide plate 73 is inclinedly fixed inside the heat exchange pipe 21 to guide the liquid inside the heat exchange pipe 21, thereby driving the plurality of fan blades 71 to rotate.

[0037] In practical implementation, the pump body drives the liquid flow within the heat exchange pipe 21. The inclined guide plate 73 directs the liquid flow, causing it to continuously impact multiple fan blades 71 located within the heat exchange pipe 21. This drives the fan blades 71 to rotate around the axis of the connecting shaft 72, which in turn drives the connecting shaft 72 to rotate synchronously. The connecting shaft 72 then transmits the rotational power to the coaxially fixed first bevel gear 81, providing stable and continuous driving power for the entire transmission unit 8. This drive unit 7 utilizes liquid flow for self-drive, requiring no additional motor power supply, resulting in energy savings and a reliable structure. It also operates synchronously with the start and stop of the circulating heat dissipation circuit, ensuring real-time matching between the driving action and the heat dissipation process. Furthermore, the drive unit can also be a structure such as a motor capable of driving the first bevel gear 81 to rotate.

[0038] Furthermore, there are two drive units 7 and two opposing first bevel gears 81, and each of the two first bevel gears 81 meshes with a second bevel gear 82. The two drive units 7 are respectively installed in two adjacent heat exchange pipes 21. The two drive units 7 work synchronously, driving the two first bevel gears 81 to rotate through the corresponding connecting shafts 72. The two first bevel gears 81 mesh with the same second bevel gear 82 at the same time, applying symmetrical and balanced driving force to the second bevel gear 82 from both sides. This avoids the second bevel gear 82 from being subjected to force on one side, resulting in uneven load, shaking, or wear. This makes the rotation of the reciprocating screw 52 more stable and reliable, thereby ensuring the stable operation of the fan 3's air cooling and dust blowing action, as well as the reciprocating dust cleaning action of the cleaning component 4. At the same time, the dual drive units 7 can provide greater driving torque, improve the overall transmission efficiency and power output stability, and ensure stable driving under liquid conditions with different flow rates. This further enhances the working reliability of the wind power transformer's heat dissipation and dust cleaning structure and extends its service life.

[0039] See Figures 1-5 In other embodiments, the connecting unit 6 includes: a first pulley 61, a second pulley 62, and a flat belt 63; the first pulley 61 is coaxially fixed on the reciprocating screw 52, ​​the second pulley 62 is coaxially fixed on the fan 3, and the first pulley 61 and the second pulley 62 are connected by the flat belt 63.

[0040] In practice, the reciprocating screw 52 rotates, causing the first pulley 61, which is fixed coaxially, to rotate synchronously. The first pulley 61 transmits power to the second pulley 62 via a flat belt 63. The second pulley 62 then drives the fan 3 to rotate coaxially, achieving synchronous operation of the reciprocating screw 52 and the fan 3. The flat belt 63 provides smooth transmission and buffers vibration, ensuring a stable fan speed. This continuously generates airflow along the length of the heat exchange pipe 21, enhancing heat dissipation and promptly blowing away dust to prevent secondary adhesion. Simultaneously, it provides a stable power foundation for the reciprocating motion of the cleaning component 4, ensuring synchronous and reliable air cooling and dust removal. Furthermore, the diameter of the first pulley 61 is larger than that of the second pulley 62. Because the diameter of the first pulley 61 is larger than that of the second pulley 62, the second pulley 62 and the fan 3 can achieve higher speeds under the transmission of the flat belt 63, thus significantly improving the airflow speed and volume of the fan 3.

[0041] Furthermore, the connecting unit can also be used for transmission in structures such as sprocket and chain drives, gear drives, and gear synchronous belts.

[0042] See Figures 1-5 In other embodiments, the connecting unit 6, the driving unit 7 and the transmission unit 8 are located at the middle position along the length of the heat exchange pipe 21, and two reciprocating screws 52, nut seats 53 and cleaning components 4 are respectively arranged opposite each other, with the two reciprocating screws 52 being coaxially fixed. In practice, the connecting unit 6, the driving unit 7, and the transmission unit 8 are arranged at the middle position along the length of the heat exchange pipe 21. The two coaxially fixed reciprocating screws 52 are synchronously driven to rotate from the middle position. The two reciprocating screws 52 drive the corresponding nut seats 53 and the cleaning components 4 to reciprocate, realizing synchronous opposite movement cleaning from the middle to both ends. This ensures that the dust in the entire length of the heat exchange pipe 21 can be wiped evenly and efficiently, avoiding cleaning blind spots. The centralized driving method in the middle makes the power transmission more stable and the structure more compact. At the same time, the two sets of reciprocating screws 52, nut seats 53, and cleaning components 4 are arranged opposite each other, which can greatly improve the cleaning coverage and cleaning efficiency. Combined with the blowing heat dissipation and dust removal of the fan 3, it further ensures that the surface of the heat exchange pipe 21 is clean and the heat dissipation area is fully utilized, effectively improving the overall heat dissipation effect and operational stability of the transformer.

[0043] See Figures 1-5 In other embodiments, two guide rods 51, fans 3, and connecting units 6 are arranged opposite each other on the reciprocating screw 52. In specific implementation, one set of guide rods 51, fans 3, and connecting units 6 are arranged opposite each other on the reciprocating screw 52. When the reciprocating screw 52 rotates, the two fans 3 are synchronously driven to rotate at the same time through the connecting units 6 on both sides, forming double the air volume and stronger airflow along the length of the heat exchange pipe 21, which not only greatly accelerates the heat dissipation speed of the circulating heat dissipation circuit, but also blows away dust more efficiently.

[0044] See Figures 1-5 In other embodiments, a heat-conducting plate 12 is also included. One end of the heat-conducting plate 12 is fixedly connected to the heat dissipation fins 11, and the other end extends into the heat exchange pipe 21. In specific implementation, one end of the heat-conducting plate 12 is fixed to the heat dissipation fins 11, and the other end extends into the heat exchange pipe 21. This allows the heat on the heat dissipation fins 11 to be directly and quickly transferred to the circulating liquid in the heat exchange pipe 21, significantly shortening the heat conduction path and improving the heat transfer efficiency from the heat dissipation fins 11 to the circulating heat dissipation loop. Combined with the increased heat dissipation area of ​​the strip-shaped cross-section of the circulating heat dissipation loop, the liquid can absorb and dissipate heat more quickly, enhancing the overall heat dissipation effect of the circulating heat exchange mechanism 2, effectively reducing the transformer operating temperature, solving the problem of insufficient heat dissipation capacity of high-power wind power transformers, and ensuring stable operation of the transformer under high-temperature conditions.

[0045] See Figures 1-5 In another embodiment, the heat dissipation fins 11 are open on the side near the transformer housing 1. In specific implementation, the open side of the heat dissipation fins 11 near the transformer housing 1 can increase the contact area between the heat dissipation fins 11 and the transformer housing 1, so that the heat generated by the transformer housing 1 can be conducted to each heat dissipation fin 11 more quickly and evenly.
