Abnormity warning device for well lid
The invention discloses an abnormity warning device for a well lid. The abnormity warning device comprises a pressure sensor, a caution rod, a spring, an angle sensor, a fixed support, a transmitting controller and a buzzer, wherein the pressure sensor is arranged between the well lid and a well wall for placing the well lid, and used for inducing whether the well lid separates from a well edge or not; the top of the caution rod is abutted against the well lid, and the bottom of the caution rod is movably connected with the fixed support; one end of the spring is connected with the caution rod, and the other end of the spring is connected with one side of the fixed support; the angle sensor is installed at the corner of the two movably connected surfaces of the fixed support and the bottom of the caution rod, and used for inducing the inclination angle of the well lid separating from the well edge; the fixed support and the transmitting controller are fixed on the well wall, and the transmitting controller is used for analysing the two paths of signals induced by the pressure sensor and the angle sensor to obtain danger level information of the well lid, and transmitting the danger level information to a monitoring and management centre; and the buzzer is used for making an alarming sound according to the danger level information. The abnormity warning device disclosed by the invention is capable of detecting the abnormal condition of the well lid, and immediately carrying out warning prompting while detecting the abnormal condition.
