Description

Technical Field

[0001] The utility model relates to the technical field of monitoring image cleaning, in particular to a monitoring image cleaning device. Background Art

[0002] The shield screw conveyor is a mechanical device used by the shield machine to discharge slag during shield tunneling construction. During the excavation process in water-rich strata, the slag has a high water content and the slag is thin, which is prone to mud splashing. In order to discharge slag smoothly, it is necessary to observe the slag discharge of the screw conveyor in time to control the screw conveyor speed and gate opening and closing degree. Therefore, it is necessary to install monitoring to observe the excavation of the screw conveyor in real time.

[0003] At present, only monitoring cameras are set up to monitor the slag discharge of the screw conveyor. During the shield advancement process, the water in front gathers in the soil bin, and the slag will splash or even gush out through the screw conveyor. The monitoring is blocked by mud and cannot judge the current slag discharge situation in time, so it is impossible to adjust the correct screw conveyor speed and gate opening and closing in time, resulting in a large instantaneous change in the soil bin pressure, disturbing the soil body, causing the next ring to discharge excessive soil, and even causing surface settlement. On the other hand, personnel need to be arranged to check whether the monitoring is affected at any time, and flush it with a water pipe when necessary, which invisibly increases manpower and time costs.
