Description

Technical Field

[0001] This utility model relates to the field of ship berthing technology, specifically to a ship auxiliary berthing system. Background Technology

[0002] Vessel berthing is a crucial aspect of port operations, and its safety and efficiency directly impact the port's normal functioning. Traditional berthing processes rely heavily on manual observation and experience, resulting in low accuracy and delayed response times. Furthermore, berthing and loading / unloading operations also present safety hazards such as fires, cable breaks, and oil spills.

[0003] Currently, existing ship berthing assistance equipment often has limited functionality, such as only basic berthing distance monitoring, and cannot provide comprehensive, real-time monitoring and early warning of cable tension, fire hazards, and oil spills. This results in a lack of effective technical support for ports when responding to sudden safety incidents, easily leading to serious casualties and property damage, and also affecting the port's operational efficiency and safety. Therefore, there is an urgent need for a ship berthing assistance system that integrates multiple monitoring functions, responds quickly, and is highly reliable to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing ship berthing systems, such as limited functionality and insufficient safety monitoring, and to provide a ship auxiliary berthing system. This system can achieve comprehensive monitoring and early warning of the ship berthing process, cable status, fire hazards, and oil spills on the water surface, thereby improving the safety and efficiency of ship berthing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A ship berthing auxiliary system includes a water surface oil spill monitoring system and a laser berthing and cable monitoring system installed on the dock, as well as an outdoor fire alarm system installed in the dock loading and unloading area and on the fire cable tray.

[0007] The oil spill monitoring system is used to monitor the leakage of oil and various oily substances in the water surface area of ​​the wharf in real time. It includes an oil spill monitoring terminal, which is connected to a monitoring computer through a communication transmission device.

[0008] The laser berthing and mooring monitoring system is used to guide ships to berth at designated berths and monitor the tension of mooring lines in real time. It includes a laser detector and a mooring line tension detection sensor. The laser detector and the mooring line tension detection sensor are connected to a monitoring calculator and a PDA handheld terminal respectively through a communication transmission device.

[0009] The outdoor fire alarm system is used to monitor and warn of fires in the dock loading and unloading area and fire cable trays. It includes an audible and visual alarm and a fire alarm button, which are connected to the fire alarm controller via cables.

[0010] The monitoring calculator and fire alarm controller are both located in the central control room outside the dock area;

[0011] The outdoor fire alarm system, laser mooring and cable monitoring system, and water surface oil spill monitoring system are all connected to UPS power supply.

[0012] The outdoor fire alarm system, laser docking and cable monitoring system, and oil spill monitoring system communicate with each other via industrial Ethernet. When the fire alarm controller detects a fire, it simultaneously sends an alarm signal to the monitoring computer to trigger an emergency stop procedure for the docking operation.

[0013] Furthermore, the cable tension detection sensor is a cylindrical pin bridge strain structure sensor, which is located at the quick release hook and coaxially mounted with the load-bearing shaft of the release hook; this structural design can ensure that the sensor accurately detects the tension change of the cable, improve the accuracy and reliability of monitoring, and facilitate installation and maintenance.

[0014] Furthermore, the oil spill monitoring terminal consists of an optical sensor and a video surveillance camera, which are arranged at intervals on the dock. The optical sensor can quickly detect oil spill substances on the water surface, while the video surveillance camera can collect real-time images of the oil spill area, making it easier for staff to intuitively understand the oil spill situation. The combination of the two improves the accuracy and comprehensiveness of oil spill monitoring, and the interval arrangement can expand the monitoring range and avoid monitoring blind spots.

[0015] Furthermore, both the audible and visual alarm and the fire alarm button are explosion-proof wall-mounted structures, fixedly installed on the steel columns of the pipe rack in the designated area. The audible and visual alarm has built-in smoke and temperature sensors, and the fire alarm button has a protective cover to prevent accidental activation. The explosion-proof structure is suitable for the flammable and explosive environment of the dock, improving the safety of the equipment. The wall-mounted installation method is simple and convenient, without taking up too much space. The built-in smoke and temperature sensors can dually monitor fire hazards, improving the timeliness and accuracy of fire alarms. The protective cover to prevent accidental activation of the fire alarm button can prevent accidental operation and ensure the stable operation of the system.

[0016] Furthermore, the central control room is located at least 50 meters away from the dock loading and unloading area. This arrangement can prevent the dangers of the dock operation area from threatening the staff in the central control room, ensuring the personal safety of the staff, and at the same time reducing the impact of noise and dust generated by dock operations on the operation of the central control equipment.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. The laser detector in the laser berthing and mooring monitoring system can accurately guide ships to berth at designated berths, improving berthing accuracy and efficiency. The mooring tension detection sensor monitors the tension status of the mooring lines in real time and transmits the data to the monitoring calculator and PDA handheld terminal, allowing staff to keep abreast of the mooring line status and avoid safety accidents caused by abnormal mooring line tension.

[0019] 2. The oil spill monitoring system monitors the oil spill situation on the dock surface in real time. Once a leak is detected, it can issue an early warning through the monitoring calculator, which will facilitate staff to take quick action and reduce pollution to the aquatic environment.

[0020] 3. The outdoor fire alarm system can effectively monitor fire hazards in the dock loading and unloading area and fire cable trays. The installation of audible and visual alarms and fire alarm buttons improves the timeliness and reliability of fire alarms. Furthermore, the systems interact with each other via industrial Ethernet. When the fire alarm controller detects a fire, it can simultaneously send an alarm signal to the monitoring computer, triggering an emergency stop procedure for berthing operations and preventing fire accidents from causing greater harm to berthing operations.

[0021] 4. All systems are connected to UPS power supply to ensure normal operation in the event of a sudden power outage, thus improving the stability and reliability of the system; the monitoring computer and fire alarm controller are located in the central control room outside the dock area, ensuring the personal safety of the staff and the stable operation of the equipment.

[0027] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0028] like Figure 1-4 As shown, a ship berthing auxiliary system includes a surface oil spill monitoring system 1, a laser berthing and cable monitoring system 2, and an outdoor fire alarm system 3.

[0029] The oil spill monitoring system 1 is installed on the dock to monitor the leakage of oil and various oily substances in the water surface area of ​​the dock in real time. It includes an oil spill monitoring terminal 4, which consists of an optical sensor and a video surveillance camera. Multiple oil spill monitoring terminals 4 are set up and arranged at intervals of 10 meters along the edge of the dock. The oil spill monitoring terminals 4 are connected to the monitoring calculator 6 through the communication transmission equipment 5. When the optical sensor detects oil spill on the water surface, it transmits the signal to the monitoring calculator 6. At the same time, the video surveillance camera captures the image of the oil spill area and transmits it to the monitoring calculator 6. The monitoring calculator 6 reminds the staff to deal with it in time.

[0030] The laser berthing and mooring line monitoring system 2 is installed on the wharf to guide ships to berth at designated berths and monitor the tension of mooring lines in real time. It includes a laser detector 7 and a mooring line tension sensor 8. The laser detector 7 is installed at the leading edge of the wharf berth to scan the ship's position information and transmit it to the monitoring calculator 6 and PDA handheld terminal 9. Staff can view the ship's position information through the PDA handheld terminal 9 and guide the ship to berth. The mooring line tension sensor 8 is a cylindrical pin bridge strain structure sensor, which is installed at the quick release hook and coaxially mounted with the load-bearing shaft of the release hook. One sensor is installed at each quick release hook. The mooring line tension sensor 8 is connected to the monitoring calculator 6 and PDA handheld terminal 9 through the communication transmission device 5 to transmit the mooring line tension data to the monitoring calculator 6 and PDA handheld terminal 9 in real time.

[0031] The aforementioned communication transmission device 5 includes a wireless module and a wired module. The PDA handheld terminal 9 is connected to the laser docking and cable monitoring system 2 via the wireless module.

[0032] The outdoor fire alarm system 3 is installed in the dock loading and unloading area and on the fire cable trays to monitor fire conditions and provide early warning. It includes an audible and visual alarm 10 and a fire alarm button 11, both of which are explosion-proof wall-mounted structures, fixed to the steel columns 15 of the pipe rack in the designated area using expansion bolts, at an installation height of 1.5 meters. The audible and visual alarm 10 has built-in smoke and temperature sensors, and the fire alarm button 11 has a protective cover to prevent accidental activation. The audible and visual alarm 10 and the fire alarm button 11 are connected to the fire alarm controller 12 via cables. When the smoke sensor detects that the smoke concentration exceeds a preset value or the temperature sensor detects that the temperature exceeds a preset value, the audible and visual alarm 10 sounds an alarm and simultaneously transmits the signal to the fire alarm controller 12. When personnel discover a fire, they can also manually press the fire alarm button 11, which also transmits the signal to the fire alarm controller 12.

[0033] Both the monitoring computer 6 and the fire alarm controller 12 are located in the central control room 13 outside the dock area, which is 50 meters away from the dock loading and unloading area. The outdoor fire alarm system 3, the laser berthing and cable monitoring system 2, and the surface oil spill monitoring system 1 are all connected to UPS 14 for power supply to ensure normal system operation during power outages. The systems interact via industrial Ethernet. When the fire alarm controller 12 detects a fire, it simultaneously sends an alarm signal to the monitoring computer 6. Upon receiving the alarm signal, the monitoring computer 6 automatically triggers the emergency berthing operation suspension procedure, stopping all ship berthing operations. Once the fire is extinguished, personnel manually resume berthing operations.
