Description

Technical Field

[0001] This utility model relates to the field of wind power generation, and in particular to a wind power generation device that facilitates heat dissipation. Background Technology

[0002] Wind power, as one of the most mature renewable energy sources, has been widely used around the world. Traditional wind power generation devices typically consist of a wind turbine, a generator, a tower, and a control system. During the power generation process, the wind turbine is driven to rotate by the wind, and the generator converts mechanical energy into electrical energy. However, due to the large amount of heat generated during long-term operation, traditional wind power generation devices have certain problems in terms of heat dissipation.

[0003] Traditional wind power generation devices mainly rely on natural heat dissipation and wind circulation for heat dissipation. However, due to the limited wind power for natural heat dissipation, the heat dissipation effect is limited. In high-temperature environments, equipment such as generators may overheat, leading to equipment damage. To address this issue, we propose a wind power generation device with improved heat dissipation. Utility Model Content

[0004] The purpose of this invention is to provide a wind power generation device that facilitates heat dissipation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wind power generation device with convenient heat dissipation includes a nacelle and a tower. An air inlet shell is fixedly connected to the upper surface of the nacelle, and an air inlet shroud is fixedly connected to one side of the air inlet shell. A fan is fixedly installed inside the air inlet shell. A generator set is installed on the inner wall of the nacelle. A bearing is fixedly embedded on the left side of the nacelle. A wind turbine is fixedly installed through the bearing at the output end of the generator set. Two sets of heat dissipation fins are fixedly connected to the outer surface of the generator set. Each set of heat dissipation fins has an internal air duct. One end of each air duct is connected to the bottom of the air inlet shell, and the other end of each air duct is connected to the bottom of the nacelle. Two air inlet windows are opened on the outer surface of the nacelle, and multiple heat dissipation holes are opened on the right side of the nacelle. A cooling fan is fixedly installed on the inner wall of the nacelle.

[0007] In a further embodiment, a cover plate is screwed onto the upper surface of the cabin, and two handles are fixedly connected to the upper surface of the cover plate.

[0008] In a further embodiment, a temperature sensor is installed on the outer surface of the generator set, and a controller is installed on the inner wall of the nacelle.

[0009] In a further embodiment, a rotary table is fixedly installed on the bottom surface of the nacelle, and a mounting base is fixedly connected to the bottom surface of the rotary table. The top of the tower is connected to the bottom surface of the mounting base.

[0010] In a further embodiment, a fixing base is fixedly connected to the bottom end of the tower, and a plurality of fixing holes are provided on the upper surface of the fixing base. Two sets of reinforcing plates are fixedly connected to the outer surface of the tower, and the bottom surface of each reinforcing plate is connected to the upper surface of the fixing base.

[0011] In a further embodiment, each of the air inlets and the heat dissipation holes is provided with a protective mesh, and the bottom of the cabin is provided with a drainage hole.

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

[0013] This device uses an air inlet window on the outside of the nacelle, which works in conjunction with a heat dissipation vent on one side of the nacelle. A cooling fan can dissipate heat from the inside of the nacelle. Two sets of heat dissipation fins are installed at the air inlet window, and the heat dissipation fins are connected to the surface of the generator set. The heat generated during the operation of the generator set is conducted to the heat dissipation fins. Air ducts are installed in the heat dissipation fins, and the air is supplied to the air ducts by a fan in the air inlet casing, which can cool the heat dissipation fins. The device uses both direct and indirect heat dissipation methods to cool the generator set, thereby ensuring that the power generation device does not overheat and that the power generation device operates normally.

An air inlet shell 14 is fixedly connected to the upper surface of the nacelle 1. An air inlet shroud 15 is fixedly connected to one side of the air inlet shell 14. A fan 23 is fixedly installed inside the air inlet shell 14. A generator set 22 is installed on the inner wall of the nacelle 1. A bearing 13 is fixedly embedded on the left side of the nacelle 1. A wind turbine 11 is fixedly installed at the output end of the generator set 22 through the bearing 13. Two sets of heat dissipation fins 17 are fixedly connected to the outer surface of the generator set 22. Each set of heat dissipation fins 17 has an internal air duct 18. One end of each air duct 18 is connected to the bottom end of the air inlet shell 14. The other end of each air duct 18 is connected to the bottom of the nacelle 1. Two air inlets 16 are opened on the outer surface of the nacelle 1. Multiple heat dissipation holes 2 are opened on the right side of the nacelle 1. A cooling fan 20 is fixedly installed on the inner wall of the nacelle 1. When the cooling fan 20 and the fan 23 are started, the cooling fan 20 cooperates with the heat dissipation holes 2 on one side of the nacelle 1 to dissipate heat inside the nacelle 1. The heat dissipation fins 17 set on the generator set 22 play a heat conduction role. When the fan 23 in the air inlet shell 14 is started, it blows air into the air duct 18. The air duct 18 and the heat dissipation fins 17 work together to cool down quickly. The power generation device is cooled by direct heat dissipation and indirect heat dissipation, thereby improving the heat dissipation effect.

[0023] A cover plate 3 is installed on the upper surface of the nacelle 1 with screws. Two handles 4 are fixedly connected to the upper surface of the cover plate 3. By setting the cover plate 3 on the nacelle 1, it is convenient to maintain the interior of the nacelle 1. A temperature sensor 21 is installed on the outer surface of the generator set 22. A controller 19 is installed on the inner wall of the nacelle 1. The temperature sensor 21 is electrically connected to the controller 19 through wires. The controller 19 is electrically connected to the fan 23 and the cooling fan 20 through wires, so as to facilitate automatic control of the fan 23 and the cooling fan 20 to start and stop according to the temperature.

[0024] A rotary table 5 is fixedly installed on the bottom surface of the nacelle 1. A mounting base 6 is fixedly connected to the bottom surface of the rotary table 5. The top of the tower 10 is connected to the bottom surface of the mounting base 6. The rotary table 5 and the mounting base 6 facilitate the connection between the tower 10 and the nacelle 1. The rotary table 5 facilitates the adjustment of the direction of the wind turbine 11 by the nacelle 1. A fixing base 8 is fixedly connected to the bottom end of the tower 10. Multiple fixing holes 9 are opened on the upper surface of the fixing base 8. Two sets of reinforcing plates 7 are fixedly connected to the outer surface of the tower 10. The bottom surface of each reinforcing plate 7 is connected to the upper surface of the fixing base 8. The fixing base 8 and the fixing holes 9 facilitate the installation of the power generation device. The reinforcing plates 7 reinforce the connection between the fixing base 8 and the tower 10. A protective net 12 is provided inside each air inlet 16 and the heat dissipation hole 2. Drainage holes are opened on the bottom surface of the nacelle 1. The protective net 12 facilitates the protection of the air inlet 16 and the heat dissipation hole 2.

[0025] The working principle of this utility model is as follows:

[0026] In use, the power generation device is first fixed in the installation position by the mounting base 8. When the wind turbine 11 is blown by the wind, the wind turbine 11 drives the generator set 22 in the nacelle 1 to generate electricity. During the power generation operation, the temperature of the generator set 22 is sensed by the temperature sensor 21, which then controls the cooling fan 20 and the fan 23 to start. The cooling fan 20 cooperates with the heat dissipation hole 2 on one side of the nacelle 1 to dissipate heat inside the nacelle 1. The heat dissipation fins 17 set on the generator set 22 play a heat conduction role. The fan 23 in the air inlet shell 14 starts to blow air into the air duct 18. The air duct 18 cooperates with the heat dissipation fins 17 to quickly cool down. The power generation device is cooled by direct heat dissipation and indirect heat dissipation, which improves the heat dissipation effect.
