Description

Technical Field

[0001] The utility model relates to the technical field of snow clearing devices, in particular to a snow clearing device for a wind turbine generator set. Background Art

[0002] A wind turbine is a power generation device that converts wind energy into mechanical energy and then into usable electrical energy for power generation. A wind turbine also includes components such as a gearbox, main bearings, electrical system, hydraulic system, braking system, and yaw system. These components work together to capture, convert, and output wind energy. With the rise of green energy and the global pursuit of sustainable development, wind turbines are finding increasingly widespread application. They are not only widely used in industries such as electricity, petroleum, metallurgy, and chemicals, but also provide reliable power support for remote, off-grid areas. Wind turbines also play a vital role in construction, transportation, municipal construction, and communications. However, existing wind turbines often accumulate large amounts of snow above the turbines during rainy and snowy weather. This not only makes it difficult for personnel to access and perform maintenance, but also increases stress on the turbine. Therefore, we have developed a snow-clearing device for wind turbines.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," "the other end," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0023] See also Figures 1-4 , the utility model provides a technical solution:

[0024] A snow clearing device for a wind turbine generator system includes a wind turbine generator system body 1, a support column 4 is installed and connected to the lower end of the wind turbine generator system body 1, a fan blade 3 is installed and connected to the rear end of the wind turbine generator system body 1, and a snow clearing mechanism 2 is fixedly connected to the right end of the wind turbine generator system body 1.

[0025] In this embodiment, the snow clearing mechanism 2 includes a base 21, a drive motor 25 is fixedly connected to the left upper end of the base 21, a support device 22 is fixedly connected to the right upper end of the base 21, the output end of the drive motor 25 is fixedly connected to the transmission rod 24, and the upper end of the transmission rod 24 is fixedly connected to the fan 23; the left end of the fan 23 is fixedly connected to the outer frame 231, the outer frame 231 is a rectangular structure, and a plurality of heating wires 232 are fixedly connected to the inner wall of the outer frame 231; the plurality of heating wires 232 are all located on the left side of the fan 23, and there is no contact between the plurality of heating wires 232 and the fan 23, and the plurality of heating wires 232 are distributed at equal distances.

[0026] Through the above scheme: the drive motor 25 is started to work, and the transmission rod 24 at its output end then rotates synchronously with the fan 23. Under the action of the drive motor 25, the transmission rod 24 rotates back and forth, and this rotational motion is transmitted to the fan 23, causing the fan 23 to swing back and forth. Subsequently, the fan 23 and the heating wire 232 are started to work. After being energized, the heating wire 232 quickly generates a large amount of heat energy. The fan 23 generates airflow, which efficiently transports the heat energy released by the heating wire 232 to the area above the wind turbine body 1. Together, they act on the snow layer above the wind turbine body 1, effectively clearing the snow through the dual effects of thermal melting and wind blowing.

[0027] In this embodiment, the support device 22 includes a support frame 221, which is an "L"-shaped structure. The left end of the support frame 221 is fixedly connected to a stabilizing sleeve 223. The stabilizing sleeve 223 is a circular structure. The upper end of the stabilizing sleeve 223 is provided with a circular groove 224 that passes through the upper and lower ends. The left part of the outer surface of the stabilizing sleeve 223 is fixedly connected to a connecting member 222; the connecting member 222 is fixedly connected to the right end of the wind turbine body 1, and the stabilizing sleeve 223 is movably connected to the transmission rod 24 through a bearing. The lower end of the support frame 221 is fixedly connected to the base 21; the base 21 is fixedly connected to the right end of the wind turbine body 1.

[0028] Through the above solution, the support frame 221 and the connecting member 222 jointly provide strong support for the stabilizing sleeve 223. The stabilizing sleeve 223 is tightly fitted on the outer surface of the transmission rod 24 through the bearing, thereby improving the stability and precision of the transmission rod 24 during rotation.

[0029] It should be noted that the present invention describes a snow-clearing device for a wind turbine. A drive motor 25 is precisely mounted on a base 21, which is fixedly mounted on the right end of the wind turbine body 1. Once the drive motor 25 is started, the transmission rod 24 at its output end rotates synchronously with the fan 23. Under the action of the drive motor 25, the transmission rod 24 rotates back and forth. This rotational motion is transmitted to the fan 23, causing the fan 23 to swing back and forth. Subsequently, the fan 23 and the heating wire 232 are started. After being energized, the heating wire 232 quickly generates a large amount of heat energy. The fan 23 generates airflow, which efficiently transports the heat energy released by the heating wire 232 to the area above the wind turbine body 1. Together, they act on the snow layer above the wind turbine body 1. Through the dual effects of thermal melting and wind blowing, the snow is effectively cleared, ensuring the continuous and efficient operation of the wind turbine. To ensure the stability of the transmission rod 24 during rotation, the support frame 221 and the connecting member 222 jointly provide strong support for the stabilizing sleeve 223. The stabilizing sleeve 223 is tightly fitted on the outer surface of the transmission rod 24 through the bearing, thereby improving the stability and precision of the transmission rod 24 during rotation.
