Sound-light alarm intelligent well lid

Abstract

The invention relates to the technical field of well lid anti-theft protection, in particular to a sound-light alarm intelligent well lid. The sound-light alarm intelligent well lid comprises connecting pipe openings, two groups of strip-shaped grooves are formed in the inner sides of the connecting pipe openings, supporting plates are fixedly connected to the strip-shaped grooves of the connecting pipe openings, connecting plates are fixedly connected to the tops of the supporting plates, round grooves are formed in the tops of the connecting plates, electric cylinders are fixedly connected to the round grooves of the connecting plates, and sliding plates are fixedly connected to the tops of piston rods of the electric cylinder. According to the sound-light alarm intelligent well lid, dueto the arrangement of a bearing cover, the risk that after a main cover is stolen, the connecting pipe openings does not have protection measures is avoided, the bearing cover can provide stable support for an auxiliary cover and the main cover, so that the bearing capacity of the main cover can be improved, due to the arrangement of the electric air cylinders, so that the bearing cover can be lifted conveniently, and due to the arrangement of a buffer spring, so that the vibration generated in the lifting process of the bearing cover can be absorbed.

Description

Technical field [0001] The invention relates to the technical field of manhole cover anti-theft protection, in particular to a sound and light alarm intelligent manhole cover. Background technique [0002] Manhole covers are used to cover roads or deep wells in homes to prevent people or objects from falling. According to the material, it can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. Generally round. It can be used for green belts, sidewalks, motor vehicle lanes, docks, alleys, etc.; in China, there are many national standards for manhole covers, single-layer, double-layer, cast iron, ductile iron, composite, cement, magnesite, etc. The value of metal will be higher, and the corresponding weight will be heavier. [0003] Based on reports about the loss of manhole covers in recent years, the reasons for the loss of manhole covers can be divided into two types: human factors and natural factors. Human fact...
