Description

A ship lock floating bollard device, monitoring device and monitoring method

technical field

The application relates to the technical field of ship lock monitoring, in particular to a ship lock floating bollard device, a monitoring device and a monitoring method.

Background technique

At present, the floating bollard of the ship lock is mainly used for berthing of large ships. This method uses buoyancy to make the mooring facilities float up and down with the change of water level, so as to meet the safety of the ship's mooring. During the use of the lock, due to reasons such as increased berthing tonnage, over-limit berthing and irregular berthing of ships, when the mooring force exceeds the tensile strength of the cable, it will cause a cable breakage accident. In addition, even if the cable can bear it, when the combined action effect caused by excessive mooring force exceeds the designed bending and shear strength of the bollard, the structure of the bollard will be damaged. Once the combined effect of the mooring force exceeds the design value of the bollard, it will cause serious consequences such as bollard breakage, uncontrolled drift of the ship, damage to the lock structure, and even secondary disasters such as the ship hitting the gate structure. For this reason, the structural mechanical characteristics of bollards under complex mooring conditions have become a major safety issue that needs to be solved urgently during the operation of the lock.

Among related technologies, academic paper 1 "Overview of On-Line Monitoring and Early Warning System for Ship Lock Floating Bollards", under the Proceedings of the 20th China Ocean Engineering Symposium, aimed at the safety of floating bollards during service Relying on a large-scale ship lock project, research and development of a complete set of technology with floating bollards as the main object of monitoring, and integrate the online monitoring and early warning system of floating bollards, and strive to realize real-time loading of floating bollards The online monitoring of the situation and the safety warning of the operation status will improve the operation management process of the ship lock floating bollard from the passive control mode of the traditional cable load measurement method to the active scientific management level based on the online monitoring and the quantitative evaluation of the safety warning. , Realize the perception of the normal state of the floating bollard of the ship lock and the warning target of the extreme state to ensure the intelligent operation and maintenance of the ship lock.

Academic Paper 2 "Research on Mooring Force Inversion Mechanism and Optical Fiber Monitoring Method of Bollard Structure", Chongqing Jiaotong University 2020 master's thesis, according to the mechanical characteristics of bollard and the characteristics of field operations, a five-point strain measurement at the root of the bollard is proposed Based on the scheme, a method for monitoring the force status of bollard structures based on fiber grating sensing technology was designed and optimized. According to the number of bollards and the structural characteristics of the wharf, the network mode of optical fiber strain sensors and the layout of optical fiber links are proposed, and a bollard cluster monitoring system integrating data collection, analysis, storage and early warning is constructed.

However, the online monitoring and early warning system in Paper 1 replaces the previous wired and centralized strain data acquisition mode with a wireless mode. In fact, when the wireless mode needs to work for years and months, the battery cannot meet the requirements, and there is still unavoidable equipment power supply. Waiting for the wired connection, some of the cables connected with the wired connection are up and down with the floating bollard, but some of the wired cables have not been effectively managed, and they have been exposed to the sun and rain for a long time, and even soaked in water. Although the monitoring method in paper 2 uses grating measurement, it does not solve the calibration problem involved in the application of grating strain measurement in the application of floating bollards.
