Embodiment Construction

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] The utility pole is installed and fixed with a cement fixed base, and if there are cracks in the part under the fixed base, it cannot be measured by traditional measurement methods.

[0029] In order to solve the above problems, the embodiment of the present application provides a detection system for the crack detection of the part of the electric pole located in the fixed base. The structure of the detection system is as follows figure 1 shown.

Abstract

The invention provides a detection system which comprises an ultrasonic probe and a control host. The ultrasonic probe is used for being placed in a vertical drill hole of a fixed base, emitting detected signals to the periphery of the vertical drill hole, receiving the reflected detected signals and sending the detected signals to the control host. The control host generates ultrasound detection images according to the detected signals and judges according to the ultrasound detection images whether slits occur in the part of a telegraph pole located in the fixed base, and when the slits occur, the control host is further used for determining dimension parameters of the slits according to the ultrasound detection images. The detection system can detect whether the slits occur in the part of the telegraph pole located in the fixed base, and it is guaranteed that a power line runs safely.

Description

technical field [0001] The invention relates to the technical field of engineering detection, more specifically, to a detection system. Background technique [0002] In the 10kV distribution network system in the suburbs and rural areas of our country, the use of utility poles is very common, and the number is huge. The operating regulations stipulate that the utility poles must not have longitudinal cracks, the width of transverse cracks must not exceed 0.2mm, and the length should not exceed 1 / of the perimeter of the utility pole. 3. When the above indicators are exceeded, there are potential safety hazards, and the poles need to be replaced in time. [0003] After installation, due to various reasons, there will be cracks in different degrees on the utility pole, which seriously affects the safe operation of the structure. The part of the pole above ground is easier to measure because it is visible. However, the part below the ground cannot be directly measured because...
