Electric heating device for lawn

The utility model discloses an electric heating device for a lawn. The electric heating device comprises grass planting grids, the system further comprises a heat tracing band and a wind power complementary power generation system. A threading hole is formed in the bottom of the side wall of each unit grid of the grass planting grid, and a wire clamping mechanism is connected to the top face of the side wall of each unit grid of the grass planting grid in an inserted mode. The output end of the wind power complementary power generation system is electrically connected with the heat tracing band, and the heat tracing band sequentially penetrates through the threading holes in the cells of the grass planting grid and the clamping hooks of the wire clamping mechanisms. The grass planting grid has the advantages that the heat tracing belts sequentially penetrate through the threading holes and the corresponding clamping hooks on the cells of the grass planting grid, natural wind energy and solar energy are used f
