Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine pitch controllers, and more specifically, to a wind turbine pitch controller with good heat dissipation. Background Technology

[0002] A wind turbine pitch controller is a device specifically designed to control the blade angle of a wind turbine. Its core function is to optimize the overall performance of the wind turbine by precisely adjusting the blade angle (a process known as "pitch control"). Specifically, the pitch controller can dynamically adjust the blade angle based on real-time wind speed and direction data, thereby maximizing wind energy capture efficiency while ensuring efficient and safe operation of the wind turbine under various wind speed conditions.

[0003] However, while pitch controllers play a crucial role in improving the performance of wind turbine generators, they also face several challenges in actual operation. Because wind turbines typically operate in harsh environments, such as high mountains or offshore platforms, where climate conditions are variable and extreme, the controller needs to withstand high loads for extended periods. This continuous high-load operation causes a significant amount of heat to be generated in the controller's internal electronic components. If this heat is not effectively dissipated, the controller's temperature will rise. Increased temperature not only affects the pitch controller's performance, slowing its response and reducing control accuracy, but may also shorten its lifespan. Prolonged operation in high-temperature environments can even damage electronic components, ultimately leading to the failure of the entire wind turbine generator.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In response to the problems in related technologies, this utility model proposes a wind turbine pitch controller with good heat dissipation to overcome the aforementioned technical problems existing in the prior art.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A wind turbine pitch controller with good heat dissipation includes a controller body, which is located inside a control box. The top of the control box has a heat dissipation vent, and a heat dissipation plate is located inside the heat dissipation vent. Rotating shafts are located at both ends of the heat dissipation plate. The rotating shafts are connected to the heat dissipation vents through bearings. A driven gear is located on one of the rotating shafts, and a toothed plate is meshed below the driven gear.

[0008] Furthermore, there are multiple heat sinks.

[0009] Furthermore, in order to drive the heat sink to rotate and facilitate the adjustment of the size of the heat dissipation vent, a drive motor is provided on one side of one of the heat sinks, and the output end of the drive motor is connected to the rotating shaft.

[0010] Furthermore, in order to limit the movement distance of the gear, the gear plate is located inside the limiting groove, which is connected to the control box.

[0011] Furthermore, a temperature sensor is installed on the top of the controller body, and the temperature sensor is connected to the controller body, which in turn is connected to the drive motor.

[0012] Furthermore, the bottom of the control box has an opening, inside which is a cooling fan, which is connected to the main body of the controller.

[0013] Furthermore, in order to absorb moisture inside the control box and prevent moisture from affecting the controller body, there are placement slots fixed on both sides inside the control box, and placement boxes are placed inside the placement slots, with drying granules inside the placement boxes.

[0014] Furthermore, springs are provided on both sides inside the placement groove, with one end of the spring connected to the placement groove and the other end connected to the fixing plate.

[0015] Furthermore, the placement box has multiple through holes.

[0016] Furthermore, a mounting bracket is provided on the outside of the control box to facilitate its installation.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) By installing a heat sink with a rotating shaft and gear transmission system at the top of the control box, the angle of the heat sink can be adjusted as needed to optimize the airflow path. Furthermore, by installing a cooling fan at the bottom of the control box, hot air inside the control box can be quickly exhausted while cold air from the outside can be introduced, forming a good air circulation. This dual heat dissipation mechanism not only significantly improves heat dissipation efficiency but also ensures that the pitch controller maintains a low temperature during high-load operation, thereby extending its service life and improving overall performance.

[0019] (2) By setting up a placement box inside the control box, which contains drying particles, the moisture inside the control box can be effectively absorbed, preventing electronic components from getting damp and extending the service life of the controller body. Attached Figure Description

[0027] 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.

[0028] According to an embodiment of the present invention, a wind turbine pitch controller with good heat dissipation effect is provided.

[0029] Example 1

[0030] like Figures 1-4As shown, the wind turbine pitch controller with good heat dissipation according to the embodiment of this utility model includes a controller body 1, which is disposed inside a control box 2. The top of the control box 2 is provided with a heat dissipation vent 3, and a heat dissipation plate 4 is provided inside the heat dissipation vent 3. There are multiple heat dissipation plates 4, which are made of aluminum alloy. Rotating shafts 5 are provided at both ends of the heat dissipation plates 4. The rotating shafts 5 are connected to the heat dissipation vent 3 through bearings. A driven gear 6 is provided on one of the rotating shafts 5. A toothed plate 7 is meshed below the driven gear 6. The toothed plate 7 is disposed inside a limiting groove 9, which is connected to the control box 2. A drive motor 8 is provided on one side of one of the heat dissipation plates 4. The output end of the drive motor 8 is connected to the rotating shaft 5. A temperature sensor 10 is provided on the top of the controller body 1 and is connected to the controller body 1. The controller body 1 is connected to the drive motor 8. An opening 11 is provided at the bottom of the control box 2. A cooling fan 12 is provided inside the opening 11 and is connected to the controller body 1. Through the above scheme, the temperature sensor 10 can measure the temperature around the controller body 1 and transmit the temperature information to the controller body 1. When the temperature sensor 10 detects that the temperature has reached a predetermined value, the controller body 1 can control the cooling fan 12 to turn on. When the temperature continues to rise, the controller body 1 can control the drive motor 8 to rotate, driving one of the gears to rotate. The rotation of the gear drives the gear plate 7 to move, thereby driving the other gears to rotate, so that the heat sink 4 rotates to a vertical state, improving heat dissipation efficiency. When the temperature reaches a safe range, the controller body 1 controls the drive motor 8 to reverse, so that the heat sink 4 returns to its initial state. When the temperature sensor 10 detects that the temperature around the controller body 1 is low, it can control the heat sink 4 to rotate to a horizontal state. This horizontal state of the heat sink 4 can reduce the entry of external cold air, maintain the temperature inside the control box 2, and prevent equipment failure due to low temperature.

[0031] like Figures 1-4 As shown, the control box 2 has placement slots 13 fixed on both sides inside, and a placement box 14 is placed inside the placement slots 13. The placement box 14 contains drying granules made of silica gel. Springs 15 are provided on both sides inside the placement slots 13, with one end of the springs 15 connected to the placement slots 13 and the other end connected to the fixing plate 16. The placement box 14 has multiple through holes 17. A mounting bracket 18 is provided on the outside of the control box 2 for mounting the control box 2. Through the above scheme, by placing drying granules inside the placement box 14, the moisture inside the control box 2 can be absorbed, preventing moisture from invading the controller body 1 and causing damage to the controller body 1. The placement box 14 is fixed by the fixing plate 16 and the springs 15, making it easy to disassemble the placement box 14 when the drying granules need to be replaced.

[0032] In summary, by utilizing the above-mentioned technical solution of this utility model, a heat sink 4 with a rotating shaft 5 and a gear transmission system is provided at the top of the control box 2. The angle of the heat sink 4 can be adjusted as needed to optimize the airflow path. Furthermore, by providing a cooling fan 12 at the bottom of the control box 2, hot air inside the control box 2 can be quickly exhausted while introducing cool air from the outside, forming a good air circulation. This dual heat dissipation mechanism not only significantly improves heat dissipation efficiency but also ensures that the pitch controller maintains a low temperature during high-load operation, thereby extending its service life and improving overall performance. Additionally, by providing a placement box 14 inside the control box 2, which contains drying particles, moisture inside the control box 2 can be effectively absorbed, preventing electronic components from getting damp and extending the service life of the controller body 1.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
