Anti-theft cable well lid

Abstract

The invention provides an anti-theft cable well lid. The anti-theft cable well lid comprises a base, a well lid body, a mechanical anti-theft device and an electronic anti-theft device. The mechanical device comprises two limiting components independent of each other. The well lid body and the base are fixed together by inserting connecting rods into corresponding limiting grooves. The electronic anti-theft device comprises a microprocessor, a trigger module, an alarm module, a password disc, a miniature infrared video tape recorder and a user terminal. Pressure signals are collected by a pressure sensor and transmitted to the microcomputer, and the false alarm prevention function, the alarm trigger function and the secondary alarm trigger function can be achieved. According to the anti-theft cable well lid, the well lid body can be separated from the base by sequentially rotating the two connecting rods by a proper angle, the possibility that a person disengages the two connecting rods from the corresponding limiting grooves in a short time under the condition of not knowing the specific structure is tiny, and if the well lid is prized up forcibly, the electronic alarm device is triggered to give out an alarm signal and transmit the alarm signal to the user terminal. According to the anti-theft cable well lid, the double anti-theft setting is adopted, the anti-theft coefficient is high, and the anti-theft effect is good.

Description

technical field [0001] The invention relates to a well cover, in particular to an anti-theft cable well cover. Background technique [0002] With the continuous development of power grid construction, the demand for power cables is also increasing. At the same time, the theft of cable manhole covers is also increasing. The theft of cable manhole covers will not only cause national property losses, but also cause the cables in the cable wells to be unsafe. If the cable well is not in operation and the manhole cover is missing, it will bring safety hazards to pedestrians and vehicles. Existing anti-theft cable manhole covers include iron chain connection method or an integrally rotating limiting device on the manhole cover body, but these designs have poor anti-theft effects, and the anti-theft design can be destroyed by simple operations. Therefore, a design with good anti-theft effect, Practical cable manhole covers are very important. Contents of the invention [0003] ...

The theft of cable manhole covers will not only cause national property losses, but also cause the cables in the cable wells to be unsafe. If the cable well without the manhole cover is not found in time, it will bring safety hazards to pedestrians and vehicles
