An urban pipe network measuring device and its measuring method

Abstract

The invention discloses an urban pipe network measurement device and a measurement method thereof. The urban pipe network measurement device comprises a casing, a storage box is fixedly arranged on the top of the casing, a control box is arranged in the storage box, and two a support mechanism for fixing the casing above the inspection shaft, an upper support plate and a lower support plate are fixedly arranged in the casing, a first motor is fixedly arranged on the upper support plate, a steel rope is wound around the output shaft of the first motor, After the steel rope passes downward through the upper support plate and the lower support plate, a heavy hammer is fixedly connected. The heavy hammer is fixedly equipped with a number of first measuring elements uniformly distributed along the circumferential direction, and the lower end of the heavy hammer is fixedly connected with a second motor. A second measuring element is fixedly arranged on the output shaft of the second motor. The invention has the advantages of low measurement complexity and high efficiency.

Description

technical field [0001] The invention relates to the technical field of underground pipeline measurement, in particular to an urban pipeline network measurement device and a measurement method thereof. Background technique [0002] With the deepening of the urbanization process, the scale of the urban underground pipe network is also expanding. However, due to the long laying time, a large number of pipes have reached or approached the service life, and even many pipes have not reached the service life due to aging and accidents. Classification of pipeline detection defects Drainage pipeline detection defects can be divided into two categories, one is structural defects, including nine types such as rupture, deformation, misalignment, disjoint, leakage, corrosion, apron shedding, branch pipe concealment, and foreign matter invasion; The category is functional defects, including 7 types of deposits, scales, obstacles, tree roots, depressions, dam heads, and scum.

AI Technical Summary

Problems solved by technology

In the prior art, the measurement of the pipe network in the inspection shaft is mainly performed manually, and the efficiency is relatively low. When using an automatic device for measurement, because the position of the device is constantly changing, the measured data needs to be converted frequently before it can be used. , with high complexity
