Integrated nodular cast iron well lid cloud background drainage efficiency detection and early warning device and method

Abstract

The invention discloses an integrated nodular cast iron well lid cloud background drainage efficiency detection and early warning device and method. The device comprises an integrated well lid and a cloud background management system, the upper end of the integrated well lid is provided with a flange, one side of the flange is provided with a hinge shaft, the hinge shaft is hinged to a well lid plate, the well lid plate is clamped with the upper end of the integrated well lid, a bottom plate is arranged at the lower end of the integrated well lid, a movable hole is formed in the bottom plate, and an odor isolation plate is movably connected into the movable hole. According to the integrated nodular cast iron well lid cloud background drainage efficiency detection and early warning device and method, the odor isolation plate is additionally arranged in the integrated well lid, the side wall of the odor isolation plate is clamped with the side wall of the integrated well lid, the odor isolation effect can be achieved, meanwhile, when rainwater above the odor isolation plate is accumulated too much, the odor isolation plate is directly pressed downwards, a piston is driven to extrude a pressure sensor, and the pressure value detected by the pressure sensor is transmitted through a control unit.

Description

technical field [0001] The invention relates to the technical field of nodular cast iron manhole covers, in particular to an integrated nodular cast iron manhole cover cloud background drainage efficiency detection and early warning device and method. Background technique [0002] Ductile iron manhole cover is a kind of ductile iron products. Nodular cast iron obtains nodular graphite through spheroidization and inoculation treatment, which effectively improves the mechanical properties of cast iron, especially improves plasticity and toughness, so as to obtain higher strength than carbon steel. Ductile cast iron is a high-strength cast iron material developed in the 1950s. Its comprehensive performance is close to that of steel. It is based on its excellent performance that it has been successfully used to cast some complex stress, strength, toughness, and wear resistance. Parts with high performance requirements. Ductile iron has rapidly developed into a cast iron materia...

AI Technical Summary

Problems solved by technology

[0003] After the installation of ductile iron manhole covers, the basic drainage function is realized, but it is difficult for city managers to know the drainage efficiency of ductile iron manhole covers, especially because of the huge number of manhole covers in the city, it is impossible to know whether each manhole cover is working normally. Therefore, it is necessary to set a drainage efficiency The detection device obtains the working efficiency of the manhole cover
