A protective plate 4 is provided at the position corresponding to each leg 302 on the inner side of the nacelle cover. The legs 302, the nacelle cover, and the protective plate 4 are connected and fixed by bolts, thereby firmly fixing the lower bracket assembly 3 to the nacelle cover. The protective plate 4 is tightly fitted to the inner side of the nacelle cover, increasing the stress area of ​​the nacelle cover, optimizing the local stress of the nacelle cover, and meeting the gravity of the upper bracket assembly and the nacelle-type lidar as well as the load of the external wind.

[0023] like Figures 2 to 4 As shown, the lower support assembly 3 includes two lower supports arranged parallel to each other. The lower support includes a crossbeam 301, a leg 302, a first fixing plate 303, and a second fixing plate 304.
