Porthole for ship

Abstract

The invention discloses a porthole for a ship, comprising a window frame, wherein a window blind and a gland are sequentially arranged at the outer end of the window frame and hinged together. A pin boss is fixed on the outer side of the window frame; and lug plates are respectively arranged on a blind frame and one side of the gland and are respectively provided with U-shaped notches. Locking pins are arranged between the pin boss and the two lug plates and are clamped in the U-shaped notches on the two lug plates. The window blind comprises the blind frame; and fire retardant glass is arranged in the blind frame. The porthole is characterized in that a sleeve frame is arranged on the outer side of the window frame; and a fire retardant plate is arranged between the sleeve frame and the window frame. Annular sealing plates for stopping the fire retardant plate are respectively arranged at the inner and outer ends of the sleeve frame and the inner and outer ends of the window frame. Annular flame-retardant rubber strips are respectively arranged between adjacent ends of the blind frame and the window frame, between the periphery of the fire retardant glass and the bottom of an axial groove, between two sides of the periphery of the fire retardant glass and the walls of two grooves and on one surface of the gland, which is adjacent to the blind frame. The porthole for the ship has the performances of sealing, preventing fire, insulating head and shielding and is suitable for outer boards of the ship, upper-layer building and the outer circumferential wall of deck of the ship.

Description

technical field [0001] The present invention relates to a window. Specifically, it is the portholes on the ship's side shell plating, ship superstructure and deck peripheral walls. Background technique [0002] It is known in the shipbuilding industry that portholes are all arranged on the side shells of ships, on the walls of superstructures and on the outdoor walls of decks. A traditional porthole mainly includes a window frame, which is welded around flat steel, and its outer end has a window leaf and a gland in turn from the inside to the outside, and one side of the window leaf and the gland is hinged by the same hinge On the corresponding side wall at the outer end of the window frame. A pin seat is fixed on the outside of the window frame, and the pin seat is on the opposite side of the hinge point of the window leaf, the gland and the window frame. Both the page frame and the side of the gland corresponding to the pin seat are fixed with ear plates, and there are ...

AI Technical Summary

Problems solved by technology

Because it only has sealing performance, once a fire breaks out outside the cabin, the ring sealing strip is easy to be burned, making the flame enter the cabin, causing harm to the equipment and personnel in the cabin

Since there is only sealing performance and no heat insulation performance, even if the sealing ring is not burned, the heat generated by the fire will enter the cabin through heat conduction, causing harm to the equipment and personnel in the cabin

Since this kind of porthole is only provided with an annular sealing strip between the page frame and the adjacent end of the window frame, there is no shielding performance, and the electromagnetic field outside the cabin will affect the electronic equipment in the cabin, making the electronic equipment in the cabin unable to work normally.
