For example, in the existing wind power blade, the wind power blade includes a blade root, a blade body and a blade tip, the blade body includes two main beams, a shell and an auxiliary beam, and the two main beams are connected by two parallel webs. After the wind power blade reaches the service life or is damaged, the wind power blade needs to be replaced, and the replaced waste fan blade occupies a large amount of land. The wind power blade is large in size and high in transportation cost, and needs to be disassembled during transportation, the blade root and the blade body are firstly separated, and then the main beam and the shell are separated. When the separated blade root and the main beam are recovered, the blade root and the main beam are firstly divided into small blocks, and the blade root and the main beam are not convenient to disassemble and break due to large volumes and strength.
