Direct insertion integrated water level gauge

The utility model provides a direct-insertion integrated water level gauge, which solves the problem that the underwater water level measurement accuracy of hydraulic structures and rock-soil slopes is easily interfered by the outside, and adopts the main technical scheme that the direct-insertion integrated water level gauge comprises a sealing shell vertically arranged in an underwater water level hole, and water filtering holes are uniformly distributed in the side body of the sealing shell; the top end of the sealed shell is in sensing communication with the outside through a signal cable, the bottom of the sealed shell is a precipitation pipe section and is fixed to an underwater water level hole in a tamping mode, a silicon pressure sensor and a water filtering pipe are further arranged in the sealed shell, the silicon pressure sensor is coaxially suspended on the inner top of the sealed shell in a hollow mode, and the top of the silicon pressure sensor is electrically connected with the signal cable th
