Description

Technical Field

[0001] The present application relates to the technical field of ship lock monitoring, and in particular to a ship lock floating bollard device, a monitoring device and a monitoring method. Background Art

[0002] At present, large ships mainly use the floating mooring bollard method in the lock, which uses buoyancy to make the mooring facilities float up and down with the change of water level to meet the safe mooring of ships. During the use of the lock, due to the increase in berthing tonnage, over-limit berthing of ships, and irregular berthing of ships, when the excessive mooring force exceeds the tensile strength of the cable, it will cause a cable break accident. In addition, even if the cable can withstand it, the combined effect of excessive mooring force exceeds the design bending and shear strength of the mooring column, which will cause the damage of the mooring column structure. Once the combined effect of the mooring force exceeds the design value of the mooring column, it will bring serious consequences such as the breakage of the mooring column, the uncontrolled drift of the ship from the cable, the damage of the lock structure, and even secondary disasters such as the ship hitting the gate structure. For this reason, the structural mechanical characteristics of the mooring column under complex mooring conditions have become a major safety issue that needs to be solved urgently during the operation of the lock.

[0003] Among the related technologies, the academic paper "An Overview of the Research on Online Monitoring and Early Warning System of Floating Mooring Bollards in Ship Locks", which is included in the Proceedings of the 20th China Marine Engineering Academic Symposium, aims to address the safety issues existing in the service of floating mooring bollards. Based on a large-scale ship lock project, a complete set of technologies with floating mooring bollards as the main monitoring object has been developed, and an online monitoring and early warning system for floating mooring bollards has been integrated, which is committed to realizing online monitoring of the real-time load conditions of floating mooring bollards and safety early warning of operating status. The operation management process of floating mooring bollards in ship locks has been upgraded from the passive control mode of traditional cable load measurement methods to the active scientific management level based on online monitoring and quantitative evaluation of safety early warning, so as to realize the perception of the normal state of floating mooring bollards in ship locks and the early warning of extreme states to ensure the intelligent operation and maintenance of ship locks.

[0004] Academic Paper 2: Research on the Inversion Mechanism of the Mooring Force of the Bollard Structure and the Fiber Optic Monitoring Method, Chongqing Jiaotong University 2020 Master's Thesis, based on the stress characteristics of the bollard and the characteristics of the on-site operation, proposed a five-point strain measurement scheme at the root of the bollard, and designed and optimized the mooring column structure stress state monitoring method based on fiber grating sensing technology. According to the number of mooring columns and the characteristics of the wharf structure, the networking mode of the fiber optic strain sensor and the layout of the fiber optic link were proposed, and a bollard cluster monitoring system integrating data acquisition, analysis, storage, and early warning was constructed.

[0005] However, the online monitoring and early warning system in the first paper replaced the previous wired, centralized strain data collection mode with a wireless mode. In fact, when the wireless mode needs to work for many years, the battery cannot meet the requirements, and the wired connection such as equipment power supply cannot be avoided. During the process of the floating mooring column, some of the wired cables are not effectively managed and are exposed to the sun and rain for a long time, and even soaked in water. Although the monitoring method in the second paper adopts the grating measurement method, it does not solve the calibration problem involved in the application of the grating strain measurement method in the floating mooring column.

A tension gauge 2 is provided in the middle of the cable 6, and the two ends of the cable 6 are respectively fastened to the same layer of mooring posts of the two floating mooring post devices 1. Specifically, the two ends of the cable 6 are fastened to the two upper mooring posts 121 or the two lower mooring posts 125 at the same time. A tensioning device 3 is also arranged in the middle of the cable 6 to provide different tensions for calibration.

[0069] The control center is connected to the tension meter 2 and the grating strain sensor 4 respectively, and provides different tensions through the tensioning device 3 in advance to obtain a tension-strain comparison table; the control center obtains the current mooring force in real time based on the tension-strain comparison table and the measurement data of the grating strain sensor 4.

[0070] It is worth mentioning that when the floating triangular prism 12 of the present application was designed, the size of the floating triangular prism 12 was specially designed so that the lower mooring post 125 and the upper mooring post 121 correspond to the mooring structure reserved for the ship itself. When mooring, the straightened cable is just horizontal; therefore, the present application calibrates the cable 6 with a tension gauge 2 in the middle to obtain a tension-strain comparison table.

[0071] Regarding the monitoring device, further, the floating bollard device 1 also includes a stepless speed regulating motor 83, which drives the cable drum 84 to rotate forward or reverse according to the change of water level, so that the cable 87 can be retracted and released in real time.

[0072] The monitoring device also includes a water level sensor 86; the water level sensor 86 and the stepless speed regulation motor 83 are both connected to the control center; the water level sensor 86 monitors the current water level in real time, and feeds back the water level signal to the control center, and the control center controls the stepless speed regulation motor 83 to rotate forward or reverse according to the water level changes of the water level sensor 86, so that the cable 87 can be retracted and released in real time, thereby achieving the purpose of synchronization between the cable 87 and the water level changes, effectively managing the cable 87, and improving the service life of the cable 87.

[0073] Furthermore, the communication power supply device 85 in the floating bollard device 1 is connected to the control center, and the communication power supply device 85 plays a transitional role and can centrally manage the electric wires and signal lines.

[0074] The present application also discloses a monitoring method using the above monitoring device, comprising the following steps:

[0076] S2: connecting two floating bollard devices 1 through a rope 6 with a tension gauge 2 in the middle, installing a grating strain sensor 4 on the force sensitive area 5 of the lower mooring post 125 and the upper mooring post 121, and calibrating the strain value measured by the grating strain sensor 4 of the floating bollard device 1 at the control center to obtain a tension-strain comparison table;

[0077] S3: During the use of the ship lock, the floating triangular prism 12 floats up and down with the change of water level, and the cable connected to the floating triangular prism 12 is adaptively retracted and released. The floating triangular prism 12 and the floating platform 13 are slidably arranged between the two columns 11 through a slip ring, and the retraction and release of the cable and the up and down sliding of the floating triangular prism 12 are performed synchronously. The control center monitors the strain of the force sensitive area 5 in real time according to the grating strain sensor 4, and converts it to obtain the mooring force being carried by the lower mooring post 125 or the upper mooring post 121.

[0078] The monitoring method of the present application first obtains the force-sensitive area 5 through simulation calculation and analysis, and then installs the grating strain sensor 4 to the force-sensitive area 5. After installation, it is calibrated to obtain a tension-strain comparison table in advance; in the process of real-time monitoring, the control center can convert the strain data in real time to obtain the mooring force. The monitoring method of the present application can accurately monitor the mooring force after prior calibration.

When subjected to tension, the measured tension is positive, and the measured data and the tension change linearly, verifying that the selected point is correct. Finally, it is proved that the measured data and the tension change linearly on the inner side of the cylinder of the upper mooring post 121 (one sensor is installed on each side at a 45-degree angle to the dam wall) and the lower side of the connecting bottom plate 126 (two sensors are installed in parallel), and both 0.1 tons of tension corresponds to 1με of the fiber grating sensor, which has good precision and accuracy.

[0080] Furthermore, the cable retracting device 8 includes two fixed bases 81, a fixed shaft 82, a cable drum 84 and a communication power supply device 85.

The communication power supply device 85 mainly performs power distribution and signal line distribution.

[0081] The floating mooring device 1 also includes a stepless speed regulating motor 83 and a water level sensor 86. The water level sensor 86 is used to monitor the current water level in real time and feed back to the control center; the control center controls the stepless speed regulating motor 83 to rotate forward or reverse according to the water level changes of the water level sensor 86, so that the cable reel 84 rotates forward and reverse, and the cable 87 is retracted and released in real time.

In the process of establishing the three-dimensional numerical simulation model, the upper structure of the ship lock floating mooring post is considered as a symmetrical structure, and its four longitudinal and transverse rollers are generalized as three-dimensional prisms.

[0089] According to the actual structural characteristics and stress conditions of the floating mooring column, the Solid186 entity unit in ANSYS Workbench is selected as the basic calculation unit of the three-dimensional numerical simulation model of the floating mooring column of the ship lock.
