Description

Technical Field

[0001] This utility model relates to the technical field of blade metal mesh, and more particularly to an extended metal mesh for electromagnetic protection of wind and thunder blades. Background Technology

[0002] Wind power generation is an environmentally friendly method of power generation and is being vigorously promoted in my country. However, wind turbine blades are the most vulnerable components to lightning strikes, resulting in the most severe damage. The quality of the blade lightning protection system directly affects the operation and economic benefits of the unit. Therefore, this paper proposes an electromagnetically protected wind and lightning-resistant extended metal mesh for wind turbine blades. This mesh can be installed on the blade surface and can be deployed and retracted at any time to provide electromagnetic protection for the blade. Simultaneously, an insulating shell is installed outside the extended assembly to protect internal components. Even if struck by lightning, the internal components will not be damaged; only the metal mesh needs to be replaced, reducing maintenance costs. Utility Model Content

[0027] Example 1

[0028] Reference Figures 1-4This is the first embodiment of the present invention, which provides an extended metal mesh for electromagnetic protection of wind and lightning blades. This device includes an extension component 100 and a protection component 200. The extension component 100 includes a slide rail 101, a rotating rod 102 disposed in the slide rail 101, a slider 103 disposed in the slide rail 101, a moving rod 104 fixedly disposed on the slider 103, and a connecting rod 105 sleeved on the moving rod 104. The protection component 200 includes a metal mesh 201 connected to the moving rod 104 and an insulating shell 202 disposed outside the slide rail 101.

[0029] The slide rail 101 is fixedly disposed in the center of the insulating shell 202. The rotating rod 102 is rotatably disposed within the slide rail 101, and a handle 102a is provided on the rotating rod 102. Several sliders 103 are provided, and each slider 103 is embedded within the slide rail 101. A moving rod 104 corresponds one-to-one with a slider 103, and a moving rod 104 is fixedly and vertically disposed on each slider 103. A connecting rod 105 corresponds one-to-one with a moving rod 104, and a connecting rod 105 is rotatably disposed on each moving rod 104. The connecting rods 105 are rotatably connected end-to-end. The end of the connecting rod 105 near the rotating rod 102 is also connected to the rotating rod 102 via a connecting rod 105a, one end of which is fixedly connected to the rotating rod 102, and the other end is rotatably connected to the connecting rod 105. The metal mesh 201 is fixedly connected to the top of the movable rod 104. The metal mesh 201 is initially in a contracted state, and the movable rod 104 is evenly distributed on the metal mesh 201. A through hole 202a is provided in the center of the top of the insulating shell 202. The movable rod 104 passes through the through hole 202a, and the metal mesh 201 is disposed outside the insulating shell 202.

[0030] During use, the metal mesh 201 in the protective component 200 can withstand lightning strikes, and the insulating shell 202 can protect the internal parts from damage. In the initial state, the metal mesh 201 is retracted by the extension component 100, and the metal mesh 201 is folded at this time, which is convenient for staff to replace or recycle. When it needs to be unfolded, the rotating rod 102 can be rotated by various driving methods, such as motors. Here, it is manually rotated. Turning the handle 102a makes the rotating rod 102 rotate, and the rotating rod 102 drives the connecting rod 105a to rotate, so that the connecting rod 105 gradually turns towards the extension direction of the slide 101, that is, the included angle between the connecting rods 105 is widened, which drives the bottom slider 103 to move and increases the distance between the sliders 103. The moving rod 104 moves in the through hole 202a, so that the metal mesh 201 unfolds. Finally, the metal mesh 201 is unfolded to form protection. When it is necessary to retract the metal mesh 201, simply reverse the above operation.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
