Automatic drainage lifting device based on sludge detection technology

The invention discloses an automatic drainage lifting device based on a sludge detection technology, and relates to the technical field of lifters. The device comprises a machine body, a driving mechanism is arranged in the machine body, the driving mechanism extends to the bottom end of the machine body, the bottom end of the driving mechanism is movably connected with a drainage bin, the inner side of the drainage bin is movably connected with a separation bin, and the inner side of the separation bin is fixedly connected with a supporting plate. Through the arrangement of the opening and closing mechanism, when a second insertion rod and a first insertion rod are longitudinally coaxial, the bottom end of the first insertion rod downwards extrudes the top end of the second insertion rod, so that an operation rod downwards moves, sealing of a control cylinder to a drainage cylinder is released, generated water can be directly discharged through a water outlet hole while mud-water separation is facilitated, a
