Water leakage detection device for directly-buried pipeline

Abstract

The invention discloses a water leakage detection device for a directly-buried pipeline. The water leakage detection device comprises a main pipe body and a control box, a supporting rod is fixedly connected to one side of the top of the main pipe body, the supporting rod is rotatably connected with the outer wall of the control box through a rotating shaft, and the bottom of the control box is connected with the outer wall of the main pipe body through a turnbuckle; the two ends of the turnbuckle are rotationally connected with the control box and the main pipe body correspondingly, one sideof the control box is fixedly connected with a display screen, and a controller, a memorizer and a power source are sequentially arranged in the control box; and a guide rod is slidably inserted in the main pipe body, a handle is fixedly connected to the top of the guide rod, and a wedge-shaped block is fixedly connected to the bottom of the guide rod. According to the water leakage detection device, through the arrangement of a temperature and humidity sensor, under the excavation-free condition, leakage points can be directly detected and quickly found for maintenance, operation energy consumption is reduced, and the situation that an ultrasonic leakage detector is adopted for detection during manual overtime work at night is avoided.

Description

technical field [0001] The invention relates to the technical field of pipeline detection equipment, in particular to a water leakage detection device for directly buried pipelines. Background technique [0002] During the operation period of the heating season, the pipelines in the old residential areas are mostly laid by direct burial. After a long period of use, the pipelines are severely corroded. Under the operating conditions of high operating pressure, they are easy to leak. The leakage time of direct buried pipelines is short and difficult to detect with the naked eye. , It will be discovered after a long time of leakage, which increases the energy consumption of the system. [0003] At present, the main leak detection devices are thermal imager and ultrasonic leak detector. When the thermal imager is buried deep in the outdoor pipeline, it is difficult to find the leak in the early stage of the leak; the ultrasonic leak detector needs to be easy to find the leak whe...
