[0002] The flexible blade root baffle for blades is a special equipment for wind power blades, mainly to solve the problem of cracking of the baffle caused by rigid connection. The flexible blade root baffle for blades is composed of multiple components, including a flexible connection ring, an installation ring, a docking disc body, a blade root baffle body, a manhole plate, a handle and a reinforcing sleeve body. These components work together to improve the overall strength and stability of the wind power blade.

[0003] The current flexible blade root baffle for blades is installed inside the wind power blade. By installing the blade root baffle on the flexible connection ring, it can reduce the force received by the blade root baffle and better buffer the force, thereby extending its service life in the wind power blade. However, due to the impact force during the long-term use of the wind power blade, the blade root baffle may be deformed. Therefore, maintenance workers need to regularly check, replace and maintain the blade root baffle. From the preparation work to the final disassembly and installation, the whole process includes multiple steps, such as releasing the adhesion, removing the bolts, disassembling the deformed parts, etc. These steps are time-consuming and laborious, and it is not convenient for maintenance workers to disassemble and install the blade root baffle from the flexible connection ring.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] The present utility model provides a technical solution: As Figure 1-2 , Figure 4-6As shown, in this embodiment, a flexible blade root baffle includes a flexible blade root baffle mechanism 100, a blade root baffle assembly 200, and a blade root baffle fixing assembly 300. The blade root baffle fixing assembly 300 includes a flexible connector 301. The flexible connector 301 is fixedly installed inside the blade root body 101 of the blade. The upper end of the flexible connector 301 is connected and fixed to a rubber backing plate 302 by screws. The flexible connector 301 can buffer and reduce the impact force on the blade root body 101, and can reduce the occurrence of deformation and cracking of the blade root baffle body 201. Further, the blade root baffle body 201 can buffer the impact force received by the blade root baffle body 201. The upper end of the rubber backing plate 302 is provided with a bottom plate 303. The upper end of the bottom plate 303 is connected and fixed to a connecting plate 311 by welding. One end of the connecting plate 311 is connected and fixed to a fixed clamping curved plate 304 by a fixing bolt 312. Threaded through holes 313 are provided inside the fixed clamping curved plate 304 and the connecting plate 311. An active bolt 307 is rotatably connected inside the threaded through holes 313. The active bolt 307 is rotatably connected inside a moving clamping curved plate 305. Installation cylinders 308 are provided at both side ends of the moving clamping curved plate 305. A first support guide post 309 and a second support guide post 310 are fixedly installed inside the installation cylinders 308. The first support guide post 309 and the second support guide post 310 are connected through and inside the fixed clamping curved plate 304. A guide post through hole 314 is provided inside the fixed clamping curved plate 304.

[0024] As Figure 1 and Figure 2 shown, a limiting curved surface platform 306 is provided at one end of the fixed clamping curved plate 304. The surface of the limiting curved surface platform 306 is in close contact with the surface of the blade root baffle body 201.

[0025] When the root baffle body 201 is inspected, maintained, disassembled, installed, and replaced by maintenance staff, when the root baffle body 201 is deformed or cracked, the maintenance staff rotates by turning the movable bolt 307. Further, the movable bolt 307 can be loosened from the fixed clamping curved plate 304. After that, by moving the movable clamping curved plate 305, the first support guide post 309 and the second support guide post 310 are further driven to move in the guide post through-hole 314 of the fixed clamping curved plate 304. By moving the movable bolt 307, the first support guide post 309, and the second support guide post 310, the movable clamping curved plate 305 is further moved. After that, the root baffle body 201 can be disassembled, replaced, and maintained, facilitating the maintenance workers to disassemble and install the root baffle from the flexible connection ring. The replaced root baffle body 201 can better withstand the wind force and various forces generated during the operation of the unit, thus ensuring the stable operation of the wind turbine. The simple operation mode of the movable bolt 307 and the clamping curved plate speeds up the disassembly speed of the root baffle body 201 and improves the maintenance efficiency.

[0026] As Figure 2-4 , Figure 6 shown, a fixed limit piece 315 is fixedly installed at one end of the fixed clamping curved plate 304, and a movable limit piece 316 is fixedly installed at one end of the movable clamping curved plate 305. The movable limit piece 316 and the fixed limit piece 315 are clamped and fixed on the surface of the root baffle body 201. The first limit groove 202 and the second limit groove 203 are opened at both side ends of the root baffle body 201. The fixed limit piece 315 is clamped and fixed inside the first limit groove 202, and the movable limit piece 316 is clamped and fixed inside the second limit groove 203.

[0027] By clamping the fixed limit piece 315 of the fixed clamping curved plate 304 inside the first limit groove 202 of the root baffle body 201, and further clamping the movable limit piece 316 of the movable clamping curved plate 305 inside the second limit groove 203, the stability of the root baffle body 201 is further clamped and fixed. When the root baffle body 201 bears the wind force and various forces generated during the operation of the unit, the situation of the root baffle body 201 shifting can be avoided. Through the action of the fixed limit piece 315 and the movable limit piece 316 being clamped in the first limit groove 202 and the second limit groove 203 of the root baffle body 201, the connection between the root baffle body 201 and the flexible connection ring is more stable, and it can effectively resist the influence of wind force and other external forces.

[0028] The utility model provides a flexible blade root baffle for blades, and the specific working principle is as follows: When the maintenance staff checks, maintains, disassembles, installs, and replaces the blade root baffle body 201, when the blade root baffle body 201 is deformed or cracked, the maintenance staff rotates by screwing the movable bolt 307. Further, the movable bolt 307 can be unscrewed from the fixed clamping curved plate 304. Then, by moving the movable clamping curved plate 305, the first support guide post 309 and the second support guide post 310 are further driven to move in the guide post through hole 314 of the fixed clamping curved plate 304. By moving the movable bolt 307, the first support guide post 309, and the second support guide post 310, the movable clamping curved plate 305 is further moved. Then, the blade root baffle body 201 can be disassembled, replaced, and maintained, which is convenient for the maintenance workers to disassemble and install the blade root baffle from the flexible connection ring. The replaced blade root baffle body 201 can better withstand the wind force and various forces generated during the operation of the unit, thus ensuring the stable operation of the wind turbine. The simple operation mode of the movable bolt 307 and the clamping curved plate speeds up the disassembly speed of the blade root baffle body 201. By clamping the fixed limit piece 315 of the fixed clamping curved plate 304 inside the first limit groove 202 of the blade root baffle body 201, and further clamping the movable limit piece 316 of the movable clamping curved plate 305 inside the second limit groove 203, the stability of the blade root baffle body 201 is further clamped and fixed. When the blade root baffle body 201 bears the wind force and various forces generated during the operation of the unit, the situation of the blade root baffle body 201 shifting can be avoided.

[0029] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
