Remote control type ship chimney shutter

Abstract

The invention discloses a remote control type ship chimney shutter which comprises a shutter body, a winch, a pulley and a steel wire rope, the winch is installed on a wall plate which is low outsidea chimney and easy to contact, long-distance operation of the shutter body is achieved through the pulley and the steel wire rope, and when a fire occurs, an operator does not need to enter the chimney. The threaded column is separated from the turbine by pulling the deflector rod body outwards at the installation position of the winch, so that the shutter cover of the shutter is closed under theaction of the gravity of the shutter cover, the function of air circulation is blocked, the safety of an operator is guaranteed, meanwhile, effective fire control can be achieved. The circular fluteddisc is movably connected with the inner wall of the tooth block ring in a clamped mode, when an operator takes up a steel wire rope to rotate, the circular fluted disc and the tooth block ring can beconnected in a clamped mode through the triangular block, the take-up roller is prevented from rotating, and therefore the window cover is fixedly locked at the height needed by the operator.

Description

technical field [0001] The invention relates to the technical field of shutters, in particular to a remote-controlled ship chimney shutter. Background technique [0002] The louvers at the top of the ship's chimney are an important window to discharge the heat in the engine room and the chimney to the atmosphere. The louvers at the top of the ship's chimney are always open when the ship is in normal operation, so as to ensure that the heat in the chimney is discharged to the atmosphere in time and can realize air pollution. To prevent the internal temperature of the engine room and the chimney from being too high, the specification requires that when a fire occurs, the shutters on the top of the chimney of the ship should be able to close the shutters in an emergency by remote control, so as to isolate the air and prevent the spread of the fire. [0003] At present, most merchant ships use hydraulic or pneumatic methods to open and close the shutters on the chimney. These tw...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of remote-control ship chimney shutter, adopt this device to work, thus solve the problem that most commercial ships in the above background use hydraulic or pneumatic shutters on the chimney, and the cost of these two control forms is relatively high. It is difficult to maintain and manage, and the ability to adapt to the environment is poor. The most important thing is that once a fire breaks out on the ship, the hydraulic system and compressed air system of the ship will often fail and cannot be used. The blinds cannot be closed in an emergency, and the air cannot be effectively isolated to prevent the spread of the fire. question
