Three-dimensional rotary antenna system for ground penetrating radar of urban underground pipeline

Abstract

The invention relates to a three-dimensional rotary antenna system for the ground penetrating radar of an urban underground pipeline, and belongs to the technical field of ground penetrating radar of an urban underground pipeline. The three-dimensional rotary antenna system comprises a shell, a rotator and a driving device; the shell is internally provided with the rotator and an antenna system, the top of the shell is provided with the driving device and an accessory box in which needed equipments are placed, and a motor is connected with the rotator through a driving member. According to the three-dimensional rotary antenna system provided by the invention, the antenna system is driven to rotate by the motor, and the ground penetrating radar can reach the 360-degree acquisition effect by stepping and rotating while acquiring, therefore an aim of synthesizing an acquired image to a three-dimensional image can be realized; furthermore, a three-dimensional imaging effect can be realized by enabling the rotation of single antenna to a multi-antenna combination, therefore the interference among multiple antennas can be prevented, and the cost caused by the multiple antennas can be saved; in addition, the three-dimensional rotary antenna system can be pushed by a manual cart in the course of using the three-dimensional rotary antenna system, thereby being suitable for the detection of the urban underground pipeline with a complicate environment.

Description

technical field [0001] The invention relates to the ground-penetrating radar antenna technology for urban underground pipelines, in particular to a rotating antenna system for three-dimensional pipeline ground-penetrating radar. Background technique [0002] Urban underground pipelines are an important infrastructure of the city and the basic guarantee for the high-quality and efficient operation of a modern city. Urban underground pipeline detection is located in the bustling area of ​​the urban area, with various types of pipelines, dense laying, large traffic of vehicles and people in the city, and complex environment. The use of urban pipeline ground-penetrating radar can accurately detect the location, buried depth and pipe diameter of underground pipelines. Construction brings great convenience, but also improves efficiency and saves money. [0003] The spatial distribution of urban underground pipelines is criss-crossed and intricate. It is no longer sufficient to r...

AI Technical Summary

Problems solved by technology

In particular, urban underground pipelines are mostly laid along the streets, and different types of pipelines are buried at different depths. These pipelines are represented by straight lines of different colors on the plan, which will be crowded and cannot be clearly displayed. If the layered display method is used , the spatial relationship between the pipelines cannot be represented, so the requirement of three-dimensional visualization is put forward in the detection of urban underground pipelines

At present, there is no well-researched 3D rotating antenna system for urban underground pipeline ground penetrating radar, especially the ground penetrating radar antenna system that can integrate stepping, rotating and collecting
