Abstract
The utility model discloses a louver opening and closing device for a marine engine room. The louver opening and closing device for the marine engine room can open or close a louver rapidly in a mechanical mode. The louver opening and closing device for the marine engine room comprises louver blades installed on a window frame, and is characterized in that the louver blades are hinged to a movable board through connecting sheets, the movable board is connected with one end of a connecting rod, the other end of the connecting rod is connected with a pull ring, and a spring is installed on the connecting rod and is positioned through a positioning board fixed to the window frame. The louver opening and closing device for the marine engine room is simple in structure. When the louver opening and closing device for the marine engine room is used, the pull ring is tensioned through a rope or a steel wire, the louver blades keep normally open, and ventilation of the marine engine room is ensured; once a fire outbreaks, people only need to release the rope or the steel wire, and the movable board enables the louver blades to rotate to be closed rapidly through the connecting sheets under the action of the spring.
Description
Technical field
The utility model relates to a kind of watercraft engine room ventilation installation, specifically a kind of watercraft engine room shutter opening and closing device.
Background technology
At present, mostly adopt shutter at the ventilation installation of marine cabin, while normally use, be generally normally open.In the time of breaking out of fire, the ventilation opening that must close cabin according to ship inspection code requirement, to play fire retardation.For this reason, have by electric motor starting louvre blade is rotated, close engine room ventilation mouth, still, if watercraft engine room is on fire, often will occur power failure situation, therefore, the method is worthless.
Summary of the invention
The purpose of this utility model is to provide a kind of mechanical means, the watercraft engine room of rapidly opened and closed shutter shutter opening and closing device of adopting.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of watercraft engine room shutter opening and closing device, it comprises the louvre blade being arranged on window-frame, louvre blade is hinged by brace and portable plate, portable plate is connected with connecting rod one end, the connecting rod other end is connected with draw ring, and spring is housed on connecting rod, and is located by the location-plate being fixed on window-frame.
Owing to adopting technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, when use, by rope or steel wire, draw ring is strained, keep louvre blade in often opening, ensure engine room ventilation, once there is fire alarm, as long as rope or steel wire are unclamped, portable plate, under spring action, closes rapidly louvre blade rotation by brace.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, a kind of watercraft engine room shutter opening and closing device, it comprises the louvre blade 1 being arranged on window-frame 4, louvre blade 1 is hinged by brace 2 and portable plate 3, portable plate 3 is connected with connecting rod 5 one end, connecting rod 5 other ends are connected with draw ring 7, and spring 8 is housed on connecting rod 5, and are located by the location-plate 6 being fixed on window-frame 1.
When the utility model application, louvre blade 1 is flexibly connected with the hole on two blocks of symmetric support plates by the axis of rotation 9 at its two ends, and gripper shoe is fixed on window-frame 4 by fixed head; Connecting rod 5 one end are provided with a hole, and draw ring 7 is connected on a hole.
When use, with rope or steel wire, draw ring 7 is strained, louvre blade 1, in often opening, ensures engine room ventilation, as shown in Figure 1.In the time there is fire alarm and need to close shutter, rope or guiding principle silk are unclamped, portable plate 3 will be moved to the left under spring 8 effects, drives brace 2 to rotate, and the rotation of brace 2 makes louvre blade 1 be rotated counterclockwise around axis of rotation 9, thus shutter is closed rapidly; Meanwhile, due to the effect of spring 8, portable plate 3 can not move, and makes louvre blade 1 having under blast and can not rotating, and reaches the effect of closing.
