A heating pipeline leakage detection device

Abstract

The utility model discloses a heating pipe leakage detection device, comprising a base, wherein a driving component is connected to the interior of the base, and a limit detection component is connected to the upper end of the driving component. The key points of the technical solution are that a hydraulic cylinder drives an output rod, a connecting plate and a thermal imager to move up and down, so that leakage conditions of heating pipes at different heights can be detected.

[0003] Application number: CN202121683277.0, discloses a heating pipe leakage detection device in a city's centralized heating network. By setting a detection mechanism, the detection mechanism can not only detect the attached heating pipe, but also detect the vicinity of the attached heating pipe, thereby greatly improving the detection range of heating pipe leakage.
