ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a powerless automatic and/or manual fire-extinguishing device, and especially to a powerless fire-extinguishing device, in which steel ropes are used to actuate a fire-extinguisher automatically or manually so that fire-extinguishing material can extinguish fire through fire-extinguishing tubes.
BACKGROUND OF THE INVENTION
The prior art fire-extinguishing structure is arranged according to the steel frames, and the smoke or high temperature sensor is exposed outsides for detecting smoke or temperature. A circuit control is used to a fire-extinguisher to actuate automatically. However, in fire accident, often power can not be supplied normally, and thus, the use of the device is not ideal. Moreover, in the prior art designs, a powerless fire-extinguishing device using steel ropes is used, while in that, the sensors and steel frames are exposed outsides and can not be enclosed. Furthermore, the steel ropes are arranged along a floor or beams so as to bent vertically. The work is hard, and thus the beauty of the room will be destroyed and it is not suitable to be used in bedroom, parlour, or cartridge with beautiful decoration.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a powerless automatic and/or manual fire-extinguishing device comprising at least one fuse sensor, a plurality of adaptor, a steel rope and an automatic actuating device of a fire-extinguisher. In the automatic sensor or manual device, a fuse sensor or a manual switch is used so that the tightness of the steel rope is varied for actuating the actuating device of a fire-extinguisher steel barrel and the gas isolating device can be driven synchronously for isolating the supply of gas. Therefore, fire is extinguished and gas flow is closed.
Another object of the present invention is to provide a powerless automatic and/or manual fire-extinguishing device, wherein the fuse sensor is supported on the V shape fixing frame. A fuse pin serves to press a steel rope to be in a standby condition. In a high temperature from a fire accident, the fuse pin will break automatically so that the steel rope is in a release condition so as to actuate a fire-extinguisher. In the whole structure, only the fuse sensor is exposed, while the other components are shielded in the ceiling. Thus, the present invention has wide application, which is especially suitable in the bedroom, or cartridge, etc with decoration.
A further object of the present invention is to provide a powerless automatic and/or manual fire-extinguishing device, wherein the adaptor serves to be penetrated by the steel rope and change direction as desired. Thus, the steel rope can be installed conveniently according to the installing place without being confined by the terrain of the floor and beam.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when reading in conjunction with the appended drawing.
