A monitoring device for submarine cables to protect them from damage from passing ships

Abstract

A monitoring device for protecting submarine cables from damage by passing ships, comprising setting a warning area (2) in the setting area of ​​the cable (4) on the sea surface, and setting a warning device (3) in the warning area (2); The warning area (2) is equipped with a remote control monitoring device (7); the control unit for the dynamic information of passing ships (1) collected by the remote control monitoring device (7), and a video display capable of displaying electronic charts and electronic charts (5); and the control unit is connected with an alarm device that can automatically alarm when the passing ship (1) enters the warning area (2) at a speed lower than the set requirement or stays in the warning area (2). The advantage of the present invention is that the operator can know the current operating status of the sea cable and the warning device and the basic information and operation conditions of the passing ships in front of the computer without leaving home, and timely understand and predict the problems that will occur on the sea cable and the ship , when the cable is abnormal, guide professionals to carry out targeted maintenance or repair immediately, effectively improving the efficiency of submarine cable maintenance or repair.

Description

technical field [0001] The invention relates to a monitoring device for protecting submarine cables from being damaged by passing ships. Background technique [0002] The safe operation of submarine cables is an important factor directly related to the normal use of electricity in island areas. In order to ensure the safe and reliable operation of these submarine cables, the existing method is to set up a professional team to be responsible for the operation of submarine cables, and set up a watchtower at each submarine cable, and the watchman will watch the submarine cable 24 hours a day Surveillance and emergency response have invested a lot of manpower and material resources, which has achieved certain results. However, these methods have also exposed some problems in the practice of several years, such as the remote location of the submarine cable watchtower, the living conditions of the watchtower watchmen are very difficult, and the observation and observation of the ...

Problems solved by technology

However, these methods have also exposed some problems in the practice of several years, such as the remote location of the submarine cable watchtower, the living conditions of the watchtower watchmen are very difficult, and the observation and observation of the watchman on duty is limited by various artificial and natural factors. Ensure that every small anomaly in the submarine cable anchorage prohibited area is observed at all times within 24 hours a day. At the same time, in recent years, with the rapid development of our city's shipping and shipbuilding The phenomenon of mooring in the submarine cable protection channel of the cross-sea transmission line under the jurisdiction is very serious, which brings harm to the safe operation of the transmission line submarine cable

For this reason, a luminous warning sign is installed at the submarine cable (ie submarine cable), but due to the environment of the luminous warning sign and the harsh weather conditions, the damage to the components of the luminous warning sign often occurs, but the line inspectors often have a strict understanding of the inspection cycle. Longer, so it is difficult to detect the failure of the luminous warning sign in time, which brings serious hidden dangers to the safe operation of the power submarine cable
