Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine blades, in particular to a novel tool for trimming the leading edge of a wind turbine blade. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. With the unsustainability of traditional fossil energy and its continued harm to the global environment, new energy sources with wind power as the mainstream have become an alternative energy source that is prioritized and vigorously developed by countries around the world. Wind turbine blades are the core components of wind turbines that convert natural wind energy into electrical energy for wind turbines, and are also the main basis for measuring the design and technical level of wind turbines.

[0003] According to a new type of tooling for trimming the leading edge of a wind turbine blade disclosed in patent announcement No. CN 209208117 U, the device drives the movement of the trimming knife through the movement of an adjusting plate, which facilitates the adjustment of the angle of the trimming knife and avoids the inconvenience of use caused by the inability to adjust the angle of the trimming knife. A sanding block is arranged on the side of the trimming knife. The sanding block is semicircular and covered with sandpaper on the outside. The hemispherical sanding block and sandpaper facilitate the refinement of the surface of the wind turbine blade after trimming, thereby improving the effect after trimming. However, when the device adjusts the adjusting plate, it is necessary to rotate the limit screw multiple times to cancel the limit with the adjusting plate, and then the adjusting plate can be adjusted, which is relatively inconvenient.

A pull rod 317 is fixedly connected to the outer end of the section rod 316, and a second spring 318 is fixedly connected to the inner side of the pull rod 317. An adjusting plate 319 is movably connected to the right side of the trimming plate 1, and an adjusting slot 3110 is provided at the front of the adjusting plate 319. An adjusting tooth 3111 is fixedly connected to the bottom of the trimming plate 1. A rotating shaft 3112 is rotatably connected inside the trimming plate 1. A pruning knife 3113 is fixedly connected to the bottom of the outer wall of the rotating shaft 3112, and a fixing tooth 3114 is fixedly connected to the upper part of the outer wall of the rotating shaft 3112. A second sliding groove 3115 is provided inside the trimming plate 1, and a second sliding rod 3116 is fixedly connected to the inner wall of the second sliding groove 3115, and a second sliding block 3117 is fixedly connected to the inner wall of the second sliding block 3116, and a connecting rod 3118 is fixedly connected to the outer side of the second sliding block 3117.

[0027] In this embodiment, the second spring 318 is fixedly connected to the connecting block 315 at one end away from the pull rod 317, the adjusting rod 316 is clamped with the adjusting groove 3110, and the adjusting tooth 3111 is meshed with the fixed tooth 3114.
