The invention discloses a sewer warning device and relates to the technical field of manufacturing of safety warning equipment. One end of a spring (1) is arranged at the upper end of the well mouth of a sewer; the other end of the spring (1) is connected with one end of a warning board (2); a displacement sensor (4) is arranged at the upper end of the well mouth; the normally-closed contact end of the displacement sensor (4) is connected with the phase line of a power supply; the other end of the displacement sensor (4) is connected with one end of a light source (3) arranged on the well wall of the sewer; the other end of the light source (3) is connected with the null line of the power supply; and the warning board (2) and the displacement sensor (4) are movably propped against the well cover of the sewer. The sewer warning device can solve the problem that a car or a passerby falls into the sewer because a warning mark is not set in time after the well cover on the well mouth of the sewer is lost.
