[0035] As shown in Figure 1 In a preferred slope deformation monitoring device, in order to reduce the erosion of rainwater on the external monitoring sensor 22, the signal processor 25 and the stress sensor 24, a protective cover is arranged on the periphery of the monitoring mechanism 2 and the fixed frame 3; the monitoring sensor, the signal processor 25 and the stress sensor 24 are arranged in the protective cover; in order to facilitate the installation of the protective cover on the monitoring mechanism 2 and the fixed frame 3, the protective cover is embedded and fixed with the monitoring mechanism 2 and the fixed frame 3.
