Description

Technical Field

[0001] This utility model relates to the field of wind power speed increaser technology, specifically a heat dissipation device for a wind power speed increaser. Background Technology

[0002] Cooling the gearbox in a wind turbine is crucial for ensuring efficient operation and extending its service life. During wind turbine operation, the gearbox transmits the low-speed rotation of the rotor to the generator via gears, generating significant frictional heat and causing the gearbox temperature to rise. Excessive temperature can alter the viscosity of the gearbox lubricating oil, affecting transmission efficiency, system stability, and even damaging components. To ensure effective cooling of the wind turbine gearbox, the following measures are typically taken: First, the gearbox design optimizes the ventilation structure to ensure smooth airflow and prevent heat buildup; second, high-performance lubricating oil with excellent thermal stability and heat dissipation helps dissipate heat and reduce frictional losses.

[0003] The utility model authorized by announcement number CN222391922U discloses a heat dissipation structure for a wind turbine gearbox. The utility model uses a support frame, strut, plate, fixing hole and positioning screws to make the heat dissipation structure of the wind turbine gearbox easy to install. In addition, the servo motor drives the rotating connecting blade to rotate and dissipate heat from the wind turbine gearbox body, resulting in good heat dissipation effect.

[0004] The aforementioned device can dissipate heat from the wind turbine gearbox body, but it does not make good use of the wind turbine gearbox body as a power source. It requires an additional drive motor to drive the fan blades to rotate and dissipate heat from the wind turbine gearbox body. In addition, the device has many fixed components, which makes the device occupy a large area and is not conducive to increasing the scope of use of the device. Therefore, a wind turbine gearbox heat dissipation device that can solve the above problems is needed. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation device for a wind turbine speed increaser box to solve the problems mentioned in the background art.

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

[0007] A wind turbine speed increaser cooling device includes a wind turbine speed increaser body. The bottom of the wind turbine speed increaser body has a heat-conducting plate. A perforated outer shell is provided on the right side of the heat-conducting plate. The heat-conducting plate is connected to the perforated outer shell by several connecting bolts. A square shell is provided on the right side of the perforated outer shell. The perforated outer shell is fixedly connected to the square shell by several connecting fixing blocks. An electric push rod is fixedly installed inside the square shell. A movable plate is fixedly installed on the output shaft of the electric push rod. The movable plate is slidably connected to the inner wall of the square shell. A rotating shaft is rotatably mounted on the movable plate via a bearing. A fan is fixedly installed on the rotating shaft. An internal transmission shaft of the wind turbine speed increaser body passes through the heat-conducting plate and the perforated outer shell, extending to the inner side of the perforated outer shell. Magnetic couplers are provided on the outer end of the transmission shaft and on the rotating shaft.

[0008] As a further embodiment of this invention, the heat-conducting plate has several heat dissipation fins.

[0009] As a further improvement of this utility model, a temperature sensor is provided on the heat-conducting plate.

[0010] As a further improvement of this utility model, the square shell is provided with several ventilation holes evenly distributed on the side near the connecting and fixing blocks.

[0011] As a further improvement of this invention, the number of fan blades is five.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The hollow outer shell and square shell are fixedly connected to the wind turbine gearbox body by connecting bolts and connecting fixing blocks, which makes it easy to fix the heat dissipation components to the wind turbine gearbox body, simplifies other fixing components, helps to reduce the size of the heat dissipation components, and thus expands the application range of the device.

[0014] 2. The energy of the drive shaft inside the wind turbine gearbox is transferred to the rotating shaft through the magnetic coupler. The rotational energy in the wind turbine gearbox can be used to dissipate heat from the gearbox, improving the energy utilization rate of the gearbox. In addition, the position of the moving plate can be adjusted by the electric push rod, thereby adjusting whether the magnetic coupler is coupled. When heat dissipation is required, the magnetic coupler is coupled, and the drive shaft inside the wind turbine gearbox drives the rotating shaft to rotate, so that the fan dissipates heat from the heat-conducting plate through the hollow outer shell, improving the operating efficiency of the device. The vent can increase the intake of outside air, which is conducive to heat dissipation of the heat-conducting plate. Attached Figure Description

[0020] Example

[0021] Please see Figures 1-3 In this embodiment of the utility model, a wind turbine speed increaser heat dissipation device includes a wind turbine speed increaser body 1. The bottom of the wind turbine speed increaser body 1 has a heat-conducting plate 2 with several heat dissipation fins. A temperature sensor is provided on the heat-conducting plate 2. A hollow outer shell 3 is provided on the right side of the heat-conducting plate 2. The heat-conducting plate 2 and the hollow outer shell 3 are connected by several connecting bolts 4. A square shell 6 is provided on the right side of the hollow outer shell 3. The hollow outer shell 3 and the square shell 6 are fixedly connected by several connecting fixing blocks 5. The hollow outer shell 3, the square shell 6 and the wind turbine speed increaser body 1 are fixedly connected by connecting bolts 4 and connecting fixing blocks 5, which facilitates the fixing of heat dissipation components on the wind turbine speed increaser body 1, simplifies other fixing components, helps to reduce the size of heat dissipation components, and thus expands the application range of the device.

[0022] The square housing 6 has several ventilation holes 7 evenly distributed on one side near the connecting fixing blocks 5. An electric push rod 8 is fixedly installed inside the square housing 6. A movable plate 9 is fixedly installed on the output shaft of the electric push rod 8. The movable plate 9 is slidably connected to the inner wall of the square housing 6. A rotating shaft 11 is rotatably installed on the movable plate 9 via a bearing 10. A fan 13 is fixedly installed on the rotating shaft 11. The internal drive shaft of the wind power speed increaser box 1 passes through the heat conduction plate 2 and the hollow outer shell 3 and extends to the inner side of the hollow outer shell 3. A magnetic coupler 12 is provided on the outer end of the drive shaft and the rotating shaft 11. The wind power speed increaser is activated through the magnetic coupler 12. The energy of the drive shaft inside the gearbox body 1 is transferred to the rotating shaft 11. The rotational energy in the wind turbine gearbox body 1 can be used to dissipate heat from the wind turbine gearbox body 1, thereby improving the energy utilization rate of the wind turbine gearbox body 1. In addition, the position of the moving plate 9 can be adjusted by the electric push rod 8, thereby adjusting whether the magnetic coupler 12 is coupled. When heat dissipation is required, the magnetic coupler 12 is coupled, and the drive shaft inside the wind turbine gearbox body 1 drives the rotating shaft 11 to rotate, so that the fan 13 dissipates heat from the heat-conducting plate 2 through the hollow outer shell 3, thereby improving the operating efficiency of the device. The vent 7 can increase the intake of outside air, which is convenient for dissipating heat from the heat-conducting plate 2.

[0023] When the device is in use, the wind turbine speed increaser body 1 rotates, transferring its own heat to the heat conduction plate 2. The temperature sensor on the heat conduction plate 2 monitors its temperature changes. When heat dissipation is required, the electric push rod 8 is activated, driving the moving plate 9 and the magnetic coupler 12 to move, causing the wind turbine speed increaser body 1 to drive the rotating shaft 11 to rotate. The fan 13 on the rotating shaft 11 dissipates heat from the heat conduction plate 2. The fins on the heat conduction plate 2 can accelerate cooling, improving the heat dissipation efficiency of the fan 13 on the heat conduction plate 2.
