The invention discloses a fingerprint anti-theft well lid. The fingerprint anti-theft well lid comprises a well base and a well lid body. A plurality of circular grooves are formed in the inner circular surface of the well base in the radial direction. A rubber layer is arranged on the end face, supporting the well lid body, of the well base. Guiding grooves are formed in the positions, corresponding to the circular grooves of the well bas, of the outer circular surface of the well lid body. Locking devices are arranged in the guiding grooves. Each locking device comprises a cylindrical block. Springs are arranged between the cylindrical blocks and the bottom surfaces of the guiding grooves. Electromagnetic blocks are arranged on the bottom surfaces of the guiding grooves. Iron blocks are arranged on the end faces, connected with the springs, of the cylindrical blocks. A fingerprint recognizer, a timer and an electric cabinet are arranged on the well lid body. The fingerprint recognizer and the timer are connected with the electric cabinet. The electric cabinet is connected with the electromagnetic blocks through a circuit. The well lid can be effectively prevented from being stolen.
Description
technical field [0001] The invention relates to the technical field of manhole covers, in particular to a fingerprint anti-theft manhole cover. Background technique [0002] Manhole covers are widely used in urban drainage, electric power, communication, heat and other underground pipe networks corresponding to the road surface. At present, manhole covers are mainly made of cast iron, which has poor anti-theft performance. Contents of the invention [0003] The purpose of the present invention is to provide a fingerprint anti-theft manhole cover to solve the deficiencies in the prior art. [0004] For realizing the object of the present invention, the technical scheme that adopts is: [0005] A fingerprint anti-theft well cover, comprising a well base and a well cover, characterized in that the inner circular surface of the well base is provided with a plurality of circular grooves along the radial direction; the end surface of the well base supporting the well cover is p...
