Description

Technical Field

[0001] The present invention relates to the technical field of cable gallery data acquisition, and in particular to an underground data acquisition and three-dimensional modeling system for a power cable well. Background Art

[0002] A cable gallery is an underground or above-ground channel system specifically used for the centralized laying of power cables, communication cables and other cables. It is an important part of modern urban infrastructure.

[0003] The types of cable corridors include the following: - **Underground integrated pipeline corridor**: Buried underground, it integrates multiple pipelines such as electricity, communications, water supply and drainage, and gas, making intensive use of underground space. It is commonly found in urban core areas or newly built urban areas.

[0004] - **Dedicated Cable Tunnel**: It is only used for laying power cables, usually has a larger cross-section, and is equipped with ventilation, lighting, and fire protection facilities. It is suitable for high-voltage cables or cable-dense areas.

[0005] - **Cable trench / cable trough**: Shallow buried open or closed trenches are low in cost and are mostly used in the construction of residential areas, factory areas or along roads.

[0006] - **Overhead cable tray**: A metal / concrete structure erected on the ground or building, which is easy to maintain but takes up ground space.

[0007] The core functions and advantages are as follows: - **Spatial optimization**: Avoid repeated excavation of the road surface and reduce the "road zipper" phenomenon.

[0008] - **Safety protection**: Anti-corrosion, waterproof, and anti-mechanical damage, reducing the risk of external force damage to the cable.

[0009] - **Easy to maintain**: Patrol personnel can enter large pipe corridors for inspection and maintenance, improving operation and maintenance efficiency.

[0010] - **Strong scalability**: Reserve space to meet future cable capacity expansion or new technology needs.

[0011] - **Disaster prevention**: Fire protection zones, monitoring systems and other designs enhance emergency response capabilities.

[0012] Nowadays, the underground environmental data monitoring equipment for power cable wells cannot perform all-round photography and scanning of the underground environment of power cable wells. Workers are required to manually rotate and shoot and scan. The degree of automation is low, and the stability of data collection is low, resulting in reduced reliability of collected data. In addition, when modeling the underground environment of power cable wells, the modeling image and the infrared temperature measurement cloud map cannot be concentrated in one model, and the display effect is not ideal.

Through a uniform 360-degree rotating motor, a supporting telescopic rod, a tripod, a DC power supply, a computer and other peripheral auxiliary equipment, it constitutes an underground detection device for the power cable well. After the underground detection device is placed in the power cable well, measurement begins to obtain physical pictures, videos, thermal imaging pictures, and latitude and longitude information of the cable well, and the detection information is sent to the industrial control computer.
