Description

Technical Field

[0001] The present invention relates to the technical field of cable tunnel engineering, and particularly relates to a cable tunnel drainage monitoring and intelligent analysis system. Background Art

[0002] The cable tunnel line is an important part of the power system, and its operation quality is of great significance for the efficient, stable, and safe operation of the power system.

[0003] The cable tunnel line is located underground, with a relatively enclosed space, very humid, prone to water accumulation, and has a harsh environment, which is not conducive to directly observing the situation inside the tunnel. It is often affected by the infiltration of groundwater and the backflow of surface water, resulting in the cable tunnel being flooded. Moreover, the ventilation condition is poor, leading to a decrease in oxygen concentration and an excessive content of toxic gases such as carbon monoxide and hydrogen sulfide, which is not conducive to personnel inspection. At the same time, it has many structural components, and it is very difficult to detect and handle faults in a timely manner, which has a certain impact on the safe operation of the power grid.

[0004] The cables and power equipment installed in the cable tunnel are required by regulations not to be immersed in water. At the beginning of the construction of the cable tunnel, waterproofing was also emphasized. However, in actual situations, the environment inside the cable tunnel is very harsh, often facing problems such as water seepage from the walls and backflow of rainwater during rain, resulting in serious water accumulation inside the cable tunnel. If the accumulated water in the cable tunnel cannot be drained out of the tunnel in time, it is very easy to cause the cables and power equipment to be submerged. In less serious cases, it will lead to the interruption of power transmission and equipment damage, and in serious cases, it will affect the personal safety of staff and others. Therefore, drainage is crucial for cable tunnels.

[0005] The traditional drainage method is to arrange personnel to drain water on-site after rain or during regular inspections when water accumulation is found. Such a method cannot detect the water accumulation in the tunnel in a timely manner and cannot meet the maintenance requirements for cable tunnels.

[0006] Currently, the disadvantages of the existing technology are that the monitoring system in the cable tunnel is not perfect, the drainage data transmission is unstable, and the uploaded data cannot be analyzed, so it is impossible to achieve early control; as a result, it is impossible to monitor and control the water accumulation in the operating cable tunnel in a timely manner, which affects the improvement of the cable operation and maintenance work efficiency and the process of the construction of the smart grid.
