[0002] Onshore wind power is a renewable energy technology that converts wind energy into electricity by building wind turbines on land. This technology utilizes the widespread wind resources in nature and converts them into electricity for human use.

[0003] The basic principle of wind power generation is to convert the kinetic energy of wind into mechanical energy through a wind turbine, and then the generator converts the mechanical energy into electrical energy. A wind turbine usually includes main components such as a tower, blades, a gearbox, and a generator.

[0030] The present invention provides a forced air-cooled wind turbine tower cabin transformer.

[0031] like Figures 1 to 2 A forced air-cooled wind turbine tower cabin transformer shown in the figure includes a controller (not shown in the figure), a communicator (not shown in the figure), a first rail 21 and a transformer body 1, wherein the first rail 21 is used to be arranged along the circumference of the tower; a first electrically controlled slide 22 is slidably arranged on the first rail 21, and the first electrically controlled slide 22 is driven to connect to the transformer body 1 on the side away from the first rail 21, and the first electrically controlled slide 22 is used to drive the transformer body 1 to slide along the first rail 21; the controller is electrically connected to the communicator and the first electrically controlled slide 22 respectively, and the communicator is used to obtain meteorological data and send it to the controller; the controller is used to determine the real-time wind direction according to the meteorological data, and control the first electrically controlled slide 22 according to the real-time wind direction.

[0032] The controller controls the first electrically controlled slide 22 to drive the transformer body 1 to slide along the first track 21 according to the real-time wind direction, so that the side of the transformer body 1 is always located in a position facing the wind direction, ensuring that the external wind force effectively cools the transformer body 1 for a long time, thereby effectively improving the cooling effect of the transformer body 1.

[0033] Specifically, the controller is used to obtain the position information of the first track 21 and the movement information of the first electrically controlled slide 22, determine the current position of the transformer body 1 based on the position information and the movement information; determine the heat dissipation position based on the real-time wind direction and position information; and control the first electrically controlled slide 22 based on the heat dissipation position and the movement information to make the transformer body 1 enter the heat dissipation position.

[0034] Specifically, the location information includes the installation position of the first track 31 on the tower and the orientation of the tower. The location information is input into the controller based on the installation position of the first track 21. The installation position of the first track 21 is determined based on the current historical wind direction, so that one end of the first track 21 is located on the side of the tower that faces the wind most frequently, and the other end of the first track 21 is located on the side of the tower that faces away from the wind most frequently.

[0035] Specifically, the first track 21 is arranged around the circumference of the tower, extending less than or equal to 180° around the tower (considering that the extended length of the first track 21 is equal to half of the tower's circumference), and the initial position of the transformer body 1 is located in the middle of the first slide rail 24. This initial position of the transformer body 1 effectively reduces the length of the cables connecting the transformer body 1 to the outside world, preventing knots and entanglement of excessively long cables during movement, ensuring that the transformer body 1 is properly connected to the turbine generator and the main control center, and ensuring that the transformer body 1 can be cooled by external wind power for most of the year.

[0036] Specifically, the heat dissipation position is located between the position facing the wind direction and the position facing the windward. When the transformer body 1 enters the heat dissipation position, the side of the transformer body 1 near the end of the first rail 21 is placed facing the wind direction. This ensures that the wind diverted by the power tower completely passes through the transformer body 1, ensuring the best heat dissipation effect.

[0037] A mounting bracket 2 is installed on the side of the first electrically controlled slide 22 facing away from the first track 21. The first electrically controlled slide 22 is connected to the transformer body 1 via the mounting bracket 2. A fan 23 is installed on the mounting bracket 2, located on the ground side of the transformer body 1. The fan 23 assists in cooling the transformer body 1. Because the first electrically controlled slide 22 moves within half a revolution of the tower, the transformer body 1 spends relatively short periods of time in the leeward direction. Therefore, the fan 23 ensures proper cooling of the transformer body 21 when in this leeward position.

[0038] An auxiliary cooling mechanism 3 is provided on the side of the transformer body 1 facing away from the first track 21. This auxiliary cooling mechanism 3 is used to assist in cooling the transformer body 1. A driver 4 is provided on the side of the fan 23 facing away from the transformer body 1. This driver 4 is connected to the auxiliary cooling mechanism 3 and is used to drive the auxiliary cooling mechanism 3 horizontally to the sides of the transformer body 1 away from the first track 21. A controller is electrically connected to the driver 4 and is used to control the driver 4 based on the real-time wind direction. The provision of the auxiliary cooling mechanism 3 cools the wind blowing toward the transformer body 1, achieving a more effective cooling effect. The provision of the auxiliary cooling mechanism 3 and driver 4 further enhances the cooling effect of the external wind on the transformer body 1.

[0039] The driver 4 includes a servo motor 41, a connecting structure, and a first fixing bracket 42. The connecting structure is laterally arranged on the side of the fan 23 facing away from the transformer body 1. The servo motor 41 is located between the connecting structure and the fan 23 and is mounted on the mounting bracket 2. The output end of the servo motor 41 drives one end of the connecting structure. The first fixing bracket 42 is located on the side of the transformer body 1 facing away from the first electrically controlled slide 22. The first fixing bracket 42 is respectively connected to the auxiliary cooling mechanism 3 and the other end of the connecting structure. The servo motor 41 is used to drive the auxiliary cooling mechanism 3 to move horizontally to each side of the transformer body 1 away from the track through the connecting structure and the first fixing bracket 42 in sequence. The controller is electrically connected to the servo motor 41 and is used to drive the servo motor 41 according to the real-time wind direction. The servo motor 41 drives the first fixing bracket 42 on which the auxiliary cooling mechanism 3 is mounted through the connecting structure to always be located in the front position of the transformer body 1 facing the wind direction, so that the wind blowing towards the transformer body 1 is uniformly cooled.

[0040] The connection structure includes a connecting rod 43, an expander 44 and a second fixed frame 45. The output end of the servo motor 41 is connected to the second fixed frame 45. The expander 44 is arranged on the second fixed frame 45. The connecting rod 43 is located between the expander 44 and the first fixed frame 42. One end of the connecting rod 43 is connected to the first fixed frame 42, and the other end of the connecting rod 43 is connected to the output end of the expander 44. The expander 44 is used to drive the auxiliary cooling mechanism 3 to approach or move away from the transformer body 1 through the connecting rod 43 and the first fixed frame 42 in sequence; a distance sensor (not shown in the figure) is provided on the side of the first fixed frame 42 facing the transformer body 1; the controller is electrically connected to the distance sensor and the expander 44, respectively. The distance sensor is used to detect the interval distance between the first fixed frame 42 and the transformer body 1 and send it to the controller. The controller is used to control the expander 44 according to the interval distance.

[0041] Specifically, the controller is configured to control the expander 44 to move the first fixing frame 42 as far away from the transformer body 1 as possible when the first electrically controlled slide 22 enters the heat dissipation position. The controller then controls the servo motor 41 based on the real-time wind direction to drive the first fixing frame 42 to the side of the transformer body 1 facing the wind. The controller then controls the expander 44 based on the spacing distance to bring the auxiliary cooling mechanism 3 closer to the transformer body 1. By controlling the distance between the auxiliary cooling mechanism 3 and the transformer body 1, the auxiliary cooling mechanism 3 is prevented from rigidly contacting the transformer body 1 during rotation, while ensuring that the auxiliary cooling mechanism 3 is as close to the transformer body 1 as possible during operation, thereby cooling the transformer body 1.

[0042] The side of the mounting frame 2 facing the connecting rod 43 is provided with a slide rail 24, a slider 26, and a sleeve 25. The slide rail 24 extends in the direction of rotation of the first fixed frame 42. The sleeve 25 extends along the length of the connecting rod 43 and is sleeved on the connecting rod 24. The sleeve 25 and the connecting rod 24 are slidably connected. The flower 26 is located between the slide rail 24 and the sleeve 25. The slider 26 is slidably connected to the slide rail 24 and fixedly connected to the sleeve 25. The sleeve 25 is connected to the slide rail 24 via the slider 26, which serves to suspend the connecting rod 43. The arrangement of the slider 26 and the arcuate slide rail 24 ensures that the sleeve 25 always suspends the connecting rod 43 during its rotation, effectively ensuring the support effect on the connecting rod 43 and the support effect of the connecting rod 43 on the first fixed frame 42.

[0043] The auxiliary cooling mechanism 3 includes a first heat exchange tube 31, a water tank 32 and a second track 33. The first heat exchange tube 31 is arranged on the side of the transformer body 1 away from the first electric control slide 22, and the first heat exchange tube 31 is provided with a first pump body 37; the driver 4 drives and connects the first heat exchange tube 31; the second track 33 is used to be arranged along the circumference of the tower; the second track 33 and the first track 21 are arranged parallel and spaced apart, and the second track 33 is located below the first track 21; the second track 33 is slidingly provided with a second electric control slide 34, and the water tank 32 is arranged on the side of the second electric control slide 34 away from the second track 33, and the second electric control slide 34 is driven to connect to the water tank 32; the water tank 32 and the first heat exchange tube 31 are connected by a connecting structure; the first pump body 37 is electrically connected to the controller, and the controller is used to control the start of the first pump body 37 to drive the water in the water tank 32 to flow through the first heat exchange tube 31 through the connecting structure. The water in the water tank 32 flows through the first heat exchange tube 31 through the connecting structure, so that the wind passes through the first heat exchange tube 31 and then blows toward the transformer body 1, thereby cooling the wind and effectively ensuring the cooling effect of the external wind on the transformer body 1.

[0044] Specifically, the auxiliary cooling mechanism 3 also includes a second heat exchange tube 35, which is disposed on the side of the fan 23 facing away from the transformer body 1. A second pump 38 is provided on the second heat exchange tube 35. A connecting structure connects the water tank 32 to the second heat exchange tube 35. The second pump 38 is electrically connected to a controller, which activates the second pump 38 and drives the water in the water tank 32 through the connecting structure to flow through the second heat exchange tube 35. The provision of the second heat exchange tube 35 further enhances the cooling effect of the fan 23.

[0045] The connecting structure includes two first telescopic hoses (not shown in the figure), which are located between the water tank 32 and the first heat exchange tube 31. One end of the two first telescopic hoses is connected to the water tank 32 respectively. The end of one first telescopic hose away from the water tank 32 is connected to one end of the first heat exchange tube 31, and the end of the other first telescopic hose away from the water tank 32 is connected to the other end of the first heat exchange tube 31.

[0046] Specifically, the connecting structure also includes two second telescopic hoses (not shown in the figure), which are located between the water tank 32 and the second heat exchange tube 35. One end of the two second telescopic hoses is connected to the water tank 32, one end of the second telescopic hose away from the water tank 32 is connected to one end of the second heat exchange tube 35, and the other end of the second telescopic hose away from the water tank 32 is connected to the other end of the second heat exchange tube 35.

[0047] Specifically, the water tank 32 is provided with two three-way joints 36, the first connections of the two three-way joints 36 are both connected to the water tank 32, the second connection of one of the three-way joints 36 is connected to one end of one of the first telescopic hoses away from the first heat exchange tube 31, and the third connection is connected to one end of the other first telescopic hose away from the first heat exchange tube 31; the second connection of the other three-way joint 36 is connected to one end of one of the second telescopic hoses away from the second heat exchange tube 35, and the third connection is connected to one end of the other second telescopic hose away from the second heat exchange tube 35.
