Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and more specifically, to a high-efficiency heat dissipation structure for wind power generation busbars. Background Technology

[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all industries has increased rapidly. Especially with the rise of numerous large factories, workshops, and high-rise buildings, traditional cables, as power transmission conductors, can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and connection. The emergence of busbar trunking has solved this problem. Busbar trunking is a closed metal device composed of copper and aluminum busbar columns, used to distribute larger power to various components of a distributed system. Busbar trunking is also required in wind power generation.

[0003] However, the heat dissipation structure of some existing wind power bus trunking is relatively simple. Most of them rely on heat dissipation fins for heat dissipation, while some have a cooling fan installed on the top of the trunking shell. These cooling fans are generally directly fixed to the trunking shell, and the area reached by the cooling air they blow is also fixed, which reduces the heat dissipation effect. Therefore, we provide a high-efficiency heat dissipation structure for wind power bus trunking. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency heat dissipation structure for wind power generation busbars, in order to solve the problems mentioned in the background art.

[0005] Currently, some existing wind power busbars have relatively simple heat dissipation structures, mostly relying on heat dissipation fins for cooling. Some also have cooling fans installed on the top of the busbar casing. However, these cooling fans are generally directly fixed to the busbar casing, and the area reached by the cooling air they blow is also fixed, which reduces the cooling effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency heat dissipation structure for a wind power generation busbar trunking includes a trunking housing. Two through slots are symmetrically distributed on the top of the trunking housing. A cooling fan is installed inside each through slot and is rotatably connected to the trunking housing. A first fixing plate is fixedly connected to the top of the trunking housing and to one side of the through slot. A swing plate is rotatably connected to the outside of the first fixing plate. A connecting plate is rotatably connected to the outside of the swing plate, away from the first fixing plate. A second fixing plate is rotatably connected to the outside of the connecting plate, away from the swing plate. The second fixing plate is fixedly connected to the cooling fan.

[0008] Preferably, a gear is fixedly connected to the outer side of the swing plate away from the first fixed plate, and the two gears mesh with each other.

[0009] Preferably, a third fixing plate is fixedly connected to the top of the wire groove housing, and a motor is fixedly connected to the outer side of the third fixing plate away from the first fixing plate.

[0010] Preferably, the output shaft of the motor passes vertically through the third fixed plate and extends to the other side of the third fixed plate, and the output shaft of the motor is rotatably connected to the third fixed plate.

[0011] Preferably, the output end of the motor is fixedly connected to a turntable, and one of the swing plates has a groove inside, with a sliding rod slidably connected inside the groove, and the sliding rod is fixedly connected to the turntable.

[0012] Preferably, the outer wall of the slide rod is in contact with the inner wall of the slide groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The starter motor drives the turntable to rotate, which in turn drives the slide bar to make a circular motion. During this process, the slide bar will squeeze the inner wall of the slide groove, thereby driving one of the two swing plates to swing up and down repeatedly. Under the action of gears, the other of the two swing plates will also swing up and down repeatedly. Finally, the swing plate drives the cooling fan to swing back and forth at a small angle through the connecting plate and the second fixed plate, so as to achieve the purpose of air sweeping, expand the heat dissipation area, and improve the heat dissipation effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 A high-efficiency heat dissipation structure for wind power generation busbar trunking includes a trunking housing 1. Two through slots 2 are symmetrically distributed on the top of the trunking housing 1. A cooling fan 3 is installed inside each through slot 2 and is rotatably connected to the trunking housing 1. A first fixing plate 4 is fixedly connected to the top of the trunking housing 1 and to one side of the through slot 2. A swing plate 5 is rotatably connected to the outside of the first fixing plate 4. When the swing plate 5 swings up and down, it can drive the cooling fan 3 to swing back and forth at a small angle via a connecting plate 6 and a second fixing plate 7. A connecting plate 6 is rotatably connected to the outside of the swing plate 5 away from the first fixing plate 4. A second fixing plate 7 is rotatably connected to the outside of the connecting plate 6 away from the swing plate 5. The second fixing plate 7 is fixedly connected to the cooling fan 3. The cooling fan 3 dissipates heat from the inside of the trunking housing 1, and its small-angle swinging motion increases the heat dissipation area and improves the heat dissipation effect.

[0021] Furthermore, a gear 8 is fixedly connected to the side of the swing plate 5 away from the first fixed plate 4. The two gears 8 mesh with each other. Under the action of the gear 8, when one of the two swing plates 5 starts to swing up and down, the other swing plate 5 will also swing up and down in the same way.

[0022] Furthermore, a third fixing plate 9 is fixedly connected to the top of the cable tray housing 1, and a motor 10 is fixedly connected to the outer side of the third fixing plate 9 away from the first fixing plate 4, so that the motor 10 is installed and fixed through the third fixing plate 9.

[0023] Furthermore, the output shaft of the motor 10 passes vertically through the third fixed plate 9 and extends to the other side of the third fixed plate 9. The output shaft of the motor 10 is rotatably connected to the third fixed plate 9. The motor 10 provides power and ultimately drives the cooling fan 3 to swing back and forth at a small angle, so as to sweep the air inside the wire groove housing 1 and improve the heat dissipation effect.

[0024] Furthermore, the output end of the motor 10 is fixedly connected to a turntable 11, and one of the swing plates 5 has a groove 12 inside. A slide rod 13 is slidably connected inside the groove 12, and the slide rod 13 is fixedly connected to the turntable 11. Of the two swing plates 5, only the one closer to the turntable 11 has a groove 12.

[0025] Furthermore, the outer wall of the slide rod 13 is in contact with the inner wall of the slide groove 12, and the slide rod 13 and the slide groove 12 are tightly fitted. When the turntable 11 rotates, the turntable 11 will drive the slide rod 13 to make a circular motion, and the slide rod 13 will press the inner wall of the slide groove 12, thereby driving the swing plate 5 to swing up and down repeatedly.

[0026] The steps of using this utility model are as follows: When using this high-efficiency heat dissipation structure for wind power generation busbar trunking, the cooling fan 3 is started to dissipate heat inside the trunking housing 1. The starting motor 10 drives the turntable 11 to rotate, and the turntable 11 drives the slide rod 13 to make a circular motion. During the process, the slide rod 13 will squeeze the inner wall of the slide groove 12, thereby driving one of the two swing plates 5 to swing up and down repeatedly. Under the action of the gear 8, the other of the two swing plates 5 will also swing up and down repeatedly. Finally, the swing plate 5 drives the cooling fan 3 to swing back and forth at a small angle through the connecting plate 6 and the second fixed plate 7 to achieve the purpose of sweeping air, expanding the heat dissipation area and improving the heat dissipation effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
