Automatic early warning device for internal deformation of dam

The invention provides an automatic early warning device for internal deformation of a dam, and relates to the field of dam devices.The automatic early warning device for internal deformation of the dam is arranged in a dam body and comprises a plurality of containing buckets, the containing buckets are arranged at equal intervals, discs are symmetrically arranged in the containing buckets, and the sides, away from each other, of the discs are connected with glass tubes; one end of the glass tube away from the disc is connected with a base. According to the automatic early warning device for dam internal deformation, a hollow disc is arranged, calcium carbonate particles, a first metal sheet, a second metal sheet and a pressure sensor are arranged in the disc, diluted hydrochloric acid reacts with calcium carbonate to generate carbon dioxide gas, and the carbon dioxide gas pushes the two metal sheets to be attached. And information is fed back to the outside in time in the dam internal deformation process. Th
