Marine anti-piracy inner opening porthole

Abstract

The invention discloses a marine anti-piracy inward-opening porthole, which comprises a window frame; The inner wall of the bulkhead is provided with a window seat, and the outer side of the window frame is provided with a groove; The end of the window seat is inserted into the groove; The groove is provided with a sealing part; The sealing member is arranged between the groove and the window seat; The outer side of the window frame is provided with a supporting member, and the supporting member is fixedly provided with a storm cover capable of closing the porthole opening; The outer edge of the window frame is fixedly provided with a hinge block, and the inner wall of the bulkhead is fixedly provided with a hinge seat. The hinge block is hinged to the hinge seat; An end plate is fixedly arranged on the outer edge of the window frame, and a locking device capable of locking the window frame and the bulkhead is fixedly arranged on the bulkhead. The porthole of the invention can providechannels for emergency natural ventilation and portable satellite signal transmission, thus ensuring the secrecy and safety of the anti-piracy cabin. The utility model has the advantages of simple structure, low manufacturing cost and convenient assembly.

Description

Technical field [0001] The invention relates to the technical field of marine equipment, in particular to a marine anti-pirate inward opening porthole. Background technique [0002] Due to the increasing frequency of global piracy activities, especially in the Gulf of Aden, Somalia and other waters, pirates often come and go, posing an increasingly serious threat to ships. In order to ensure the safety of the crew and cargo, a place for the crew to hide after the pirates successfully board the ship is usually set up, that is, an anti-pirate cabin. [0003] Usually the anti-piracy cabin is arranged below the main deck, in a safe and concealed area with a solid steel wall. The conventional ventilation facilities of this cabin are arranged on the deck, and concealment measures are taken on the nameplate of the ventilator. [0004] After the pirates board the ship, their primary goal is to find the crew and control the hostages. Once the pirates closed all the compartments for ventila...

AI Technical Summary

Problems solved by technology

Once the pirates shut off all cabin ventilation, the anti-pirate cabin becomes unsafe

[0005] In addition, the existing anti-piracy cabin is surrounded by steel plates, which are solid and may also block the portable satellite phone signal. Without a good communication channel, timely rescue work will be affected

[0006] Therefore, the portholes of the existing anti-piracy cabin cannot meet the requirements of ventilation and communication signal transmission, and there is a large potential safety hazard
