When a fire occurs, flame enters the interior of the air bus duct body 1 and heats the bottom of the longitudinally-arranged metal piston outer shell 304, then the liquid medium A305 is heated and evaporated, so that heated hot steam drives the first wedge-shaped slider 309 to move upwards and pushes the second wedge-shaped slider 310 to move towards the horizontal direction, the second wedge-shaped slider 310 pushes the second piston seat 312 to move horizontally through the push-pull rod B, the second piston seat 312 then pushes the fireproof plate 302 to move gradually towards the direction far away from the metal placing box 303 through the push-pull rod A and to be separated from the interior of the metal placing box 303, under the action of the elastic force of the expansion spring 318, the two inner fireproof plates 317 are ejected from the interior of the plate slot on the fireproof plate 302 rapidly, so that a row of structures for fire stopping is formed by the hollow metal box body 300, the transversely-arranged metal piston outer shell 314, the metal placing box 303 and the plurality of ejected inner fireproof plates 317, and the flame inside of the air bus duct body 1 can be blocked, and accordingly, the flame can be effectively prevented from spreading in the interior of the air bus duct body 1.
When flame exists in the air bus duct body 1, the flame can heat the outer wall of the metal piston outer shell 314 transversely, so that the liquid medium B316 is heated and heats the shape memory alloy wire 315 in the metal piston outer shell, the shape memory alloy wire 315 is gradually restored to the spiral curling state after being heated and is similar to the spiral curling state of a spring, the shape memory alloy wire 315 from the restored to the curling state pulls the second piston seat 312 to move towards the metal placing box 303, the moving speed of the second piston seat 312 can be further accelerated, the moving speed of the fireproof plate 302 is indirectly improved, the time of separating the fireproof plate 302 from the metal placing box 303 is shortened, the time of separating and popping the inner fireproof plate 317 from the inside of the metal placing box 303 is further shortened, the fire condition in the air bus duct body 1 is blocked, and the blocking effect of the air channeling blocking mechanism on the fire condition spreading in the air bus duct body 1 is further improved.
When the second piston seat 312 moves towards the metal placing box 303, the second piston seat 312 presses the liquid medium B316 and increases the pressure inside the transverse metal piston outer shell 314, and then the liquid medium B316 pushes the blocking ball 401, so that the liquid medium B316 inside the transverse metal piston outer shell 314 enters the bottom metal hollow box 400 and is guided into the longitudinal metal piston outer shell 304 through the drainage tube 404.
The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
