Sound insulation chock for ship

Abstract

The invention relates to a sound insulation chock for a ship. The sound insulation chock for the ship comprises a door sheet and a door frame. One group of corresponding sides of the door sheet and the door frame are connected in a hinge mode, and a locking mechanism is arranged between the door sheet and the door frame except a hinge edge. The door sheet and the door frame are all in a hollow shape with sound insulation materials filled inside. The sound insulation chock for the ship is characterized in that the inner edge of the outer lateral face of the door frame and the edge of the inner edge of the door sheet are all provided with convex ribs arranged horizontally along a circumferential direction, and a door sheet corresponding to the convex ribs of the door frame and the door frame corresponding to the convex ribs of the door sheet are all fixed with a sealing strip; the protruding length of the convex ribs on the door frame is larger than a horizontal thickness of the sealing strip on the door frame, and the protruding length of the convex ribs on the door sheet is larger than the horizontal thickness of the sealing strip on the door sheet. The sound insulation chock has high sealing and sound insulation performance, and the sealing strips are difficult to damage.

Description

technical field [0001] The invention relates to a hatch on a ship, in particular to a hatch with sound-insulating and gas-blocking effects, and is especially suitable for being installed in engine room walls and control rooms of military auxiliary ships, civil and marine ships, and the like. Background technique [0002] As we all know, in the field of ships, the engine room and control room of military auxiliary ships, civil and offshore ships are mainly used to set the power plant of the ship, and these power plants will generate huge noise and exhaust gas during operation. Therefore, it is necessary to A hatch with sound-proof and air-blocking function is installed at the exit of such engine room wall and control room, and its function is to isolate the noise and air pollution to other spaces inside the ship when the equipment in the engine room and control room is in operation. [0003] The traditional sound insulation choke doors used in the engine room and control room...

AI Technical Summary

Problems solved by technology

However, since the sound insulation choke only uses a sealing strip to make surface-to-face contact with the plate, when the pressure in the engine room or control room is too high or the sealing strip is aging, the gas in the room will still pass through the space between the sealing strip and the plate. This will affect the sealing performance of the sound insulation choke door, and at the same time make the sound insulation effect around the door panel poor, and when the gas passes through, it will generate friction on the sealing strip, which will easily cause damage to the sealing strip
