Description

High-voltage shore power safety access system and method for ship dangerous area Technical Field The application relates to the technical field of ships, in particular to a high-voltage shore power safety access system and method for a ship dangerous area. Background With increasing strictness of emission reduction requirements of international maritime organization (International Maritime Organization, abbreviated as IMO) and ports of various countries during port approaching of ships, a ship shore Power system (ALTERNATIVE MARITIME Power, abbreviated as AMP) has become a key means for reducing atmospheric pollution and noise pollution in port areas, and has a core function of replacing ship self Power generation equipment during port berthing of ships, supplying Power to the ships through a shore Power supply so as to reduce port pollutant emission. For oiled ships such as oil tankers and chemical ships, the auxiliary machinery is stopped during harbor period, and the shore power is switched, so that carbon emission is reduced, and the operation safety and the environment protection compliance can be obviously improved. At present, the high-voltage shore power system of the oiled ship is usually arranged in a safety area at the stern of the ship, and the key advantage of the scheme is that the environment characteristic of the safety area is utilized, no additional explosion-proof measures are needed, and the design complexity of the high-voltage shore power system is reduced. The application of the high-voltage shore power system on the oiled ship is limited by various factors, so that the large-scale popularization cannot be realized: From the aspect of regulation, the special regulation and standard system for using the high-voltage shore power system for the oiled ship is not perfect, and the standard requirements of different areas and different ports on the shore power access of the oiled ship are different, so that the shipmen face a plurality of uncertainties in the implementation process; From the aspect of wharf infrastructure construction, the berthing wharf of many oiled ships lacks a matched high-voltage shore power facility, and a great deal of funds are required to be invested in constructing the high-voltage shore power infrastructure, and the construction method involves a plurality of complex projects such as wharf power system transformation, shore power equipment purchase and installation and the like, and is high in cost and long in construction period; from the aspect of safety problems, most of the oil-based ships are inflammable and explosive chemicals or oil products, and once electrical faults, electricity leakage and other conditions occur in the process of using the high-voltage shore power system, serious safety accidents such as fire and explosion are extremely easy to cause, so that all parties have cautious attitudes on the application of the high-voltage shore power system of the oil-based ships. In addition, the stern setting scheme adopted by the high-voltage shore power system of the oiled ship has obvious adaptation defects under specific wharf scenes, namely, for a butterfly wharf, the wharf is usually composed of a middle header area and two sides of mooring piers, the oiled ship can only be abutted with wharf facilities through a midship area close to the wharf header area, and the bow and stern of the oiled ship cannot be close to a shore power socket due to the fact that the stern is far away from the mooring piers. Therefore, even if the oiled vessel is equipped with a stern shore power interface, an effective connection cannot be achieved due to too far distance, limited cable length or unreachable hoisting equipment. Disclosure of Invention In view of the above, the main purpose of the present application is to provide a high-voltage shore power safety access system and method for a dangerous area of a ship, which are beneficial to solving the problems that the existing high-voltage shore power technology is only suitable for non-dangerous areas, the safety risk of setting the high-voltage shore power system in the dangerous area is uncontrollable, the high-voltage shore power system is not matched with the layout of an oiling wharf, and the suitability of different ship types is poor. In a first aspect, the present application provides a high voltage shore power security access system for a hazardous area of a ship, comprising: The high-voltage shore power connection cabin is positioned in a 1-type dangerous area or a 2-type dangerous area in a midship dangerous area of the ship, a high-voltage shore power socket connected with a high-voltage shore power access distribution board positioned in a ship safety area is arranged in the high-voltage shore power connection cabin, a first multi-parameter safety assembly is arranged on the inner side of a bulkhead of the high-voltage shore power connection cabin, and a first airtight through piece is arranged on the bu
