Electromagnetic shield door

Abstract

The invention relates to an electromagnetic shield door. The electromagnetic shield door comprises a door frame and a leaf, which are hinged together, wherein an outer convex edge is formed on the inner rim of the door frame, a groove is formed on the inner side edge of the leaf, and a rubber strip is arranged in the groove; a door cutter is arranged inside the groove, a shielding groove is arranged in the door frame, spring plates are circumferentially arranged inside the two walls of the shielding groove, and the two sides of the door cutter are closely contacted with the two spring plates when the door cutter is inserted into the shielding groove; a shielding short tube is arranged inside the door cutter, spring plates are circumferentially arranged on the outer surface of the wall of the shielding short tube, and the convex faces of the spring plates are opposite and closely contacted with the outer side face of the groove which is in the inner side of the shielding groove; and axle holes are formed on the leaf inside the four walls of the shielding short tube, an axle sleeve is arranged inside each axle hole, and a rotating shaft is arranged in each axle sleeve. The electromagnetic shield door has the characteristics that circumferential grooves are formed on the rotating shaft, and seal rings are arranged inside the circumferential grooves. The electromagnetic shield door has a watertight function, and is suitable for separation plates among cabins of a dark chamber in the lower part of a ship.

Description

technical field [0001] The invention relates to an electromagnetic shielding door. Specifically, it is the electromagnetic shielding door on the isolation plate between the various cabins in the lower part of the ship. Background technique [0002] It is known in the shipbuilding industry that the lower part of the ship is equipped with a cabin useful as a darkroom. In order to facilitate the passage of personnel between each darkroom, electromagnetic shielding doors are arranged on the isolation plates between two adjacent darkrooms. A traditional electromagnetic shielded door comprises a door frame and a door leaf, both of which are rectangular, and their vertical sides are hinged together by hinges. The inner edge of the door frame has an outer convex edge, and the inner edge of the door leaf has a groove, and a rubber strip is arranged in the groove, and the rubber strip abuts against the outer convex edge when the door leaf is closed. There is a door knife correspond...

AI Technical Summary

Problems solved by technology

When a ship encounters a collision and water enters a dark room, due to the high underwater pressure, the water with high pressure will enter the adjacent dark room along the gap between the rotating shaft and the shaft sleeve, which will affect the personnel and equipment in the adjacent dark room. bring harm

Therefore, the above-mentioned electromagnetic shielding door has no watertight function. When the ship encounters a collision and causes a dark room to enter water, the water with relatively high pressure will enter the adjacent dark room along the gap between the rotating shaft and the shaft sleeve, and the personnel in the adjacent dark room will be affected. harm to equipment
