The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-5, the present embodiment provides a fire protection and smoke exhaust device, which includes:

the top edge frame of the inner window frame 1 is rotatably installed in an inner cavity of the top edge frame of the outer window frame 2 through a rotating mechanism 3 so as to be capable of being driven by the rotating mechanism 3 to be opened in a rotating mode towards the back side; a blocking piece 4 is arranged on the back side surface of the top frame, and the top side edge of the blocking piece 4 is hinged with the top frame; a ventilation mechanism 5 is arranged on the side frame and/or the bottom frame of the outer window frame 2;

a fire monitoring system 6, said fire monitoring system 6 comprising a control panel 61 and a processor 62, smoke sensor 63, temperature sensor 64 and controller 65 mounted within said control panel 61; the processor 62 is in data control connection with the smoke sensor 63, the temperature sensor 64 and the controller 65 to generate a control instruction for the controller 65 according to the smoke information and the temperature information detected by the smoke sensor 63 and the temperature sensor 64;

the controller 65 is in data control connection with the rotating mechanism 3 and the ventilation mechanism 5, so as to control the opening or closing of the rotating mechanism 3 and the ventilation mechanism 5 according to the control instruction.

This fire control fume extractor has adopted the second grade smoke exhaust structure, and the first order smoke exhaust structure is the ventilation mechanism 5 that sets up on the side frame of outer window frame 2 or the end frame, and the second grade smoke exhaust structure is interior window frame 1 and slewing mechanism 3 complex structure. Glass, plastic transparent plates or opaque plate surfaces and the like can be arranged in the frame of the inner window frame 1 according to requirements, and the arrangement is not limited herein. The fire monitoring system 6 is in control connection with the ventilation mechanism 5 and the rotating mechanism 3 of the two-stage smoke exhaust structure, when the smoke sensor 63 and the temperature sensor 64 detect smoke information and temperature information, the processor 62 processes and analyzes the smoke information and the temperature information according to preset program information, and identifies whether the current smoke information and temperature information is a fire condition, and whether the current smoke information and temperature information is a slight grade or a serious grade and the like in the case of the fire condition. The preset program and the fire level can be set by those skilled in the art according to the actual conditions of the building, for example, the fire level can also be set to a light level, a medium level and a severe level, which is not limited herein.

When the processor 62 determines that the fire condition is a mild level, it may issue a control command to control the opening of the ventilation mechanism 5 through the controller 65, so as to automatically implement the smoke discharging function through the ventilation mechanism 5. When the processor 62 determines that the fire is serious, it may issue a control command to control the turning mechanism 3 to be turned on by the controller 65, and continue to open the inner sash 1 toward the back side (the back side is the outdoor side with respect to the building) with respect to the outer sash 2, thereby opening the entire window. As shown in fig. 2, when the rotating mechanism 3 rotates itself and drives the inner window frame 1 to open towards the back side, the inner window frame 1 applies an acting force towards the back side to the blocking piece 4, and the blocking piece 4 rotates along the hinge position under the acting force, so that the opening of the inner window frame 1 is not interfered. The window that opens not only can discharge fume but also can be through the window of opening as fire control passageway, dredges indoor personnel or supplies fire fighter to get into. When the inner sash 1 is rotated back and closed, the flap 4 is also rotated back along the hinge position under the influence of gravity, blocking the gap between the inner sash 1 and the outer sash 2.

Therefore, through fire control monitored control system 6 with slewing mechanism 3 with ventilation mechanism 5's control connection, alright in time detect the conflagration degree when the conflagration takes place, open ventilation mechanism 5 or whole interior window frame 1 according to the conflagration condition of reality, in time assist the rescue work of conflagration.

Referring to the structural state of the left side frame in fig. 1 or the state change of fig. 3 to 5, when the shielding plate 53 moves leftward in the illustrated direction, the abutting hole 531 and the ventilation hole 51 abut against each other, so that the ventilation hole 51 penetrates through the entire structure of the side frame or the bottom frame, and the ventilation of the room is achieved by the penetration state of the ventilation hole 51. When there is no fire, the first driving assembly 52 drives the shielding plate 53 to move rightward, so that the abutting hole 531 and the ventilation hole 51 are misaligned with each other, and the ventilation hole 51 is shielded by the shielding plate 53 except for the abutting hole 531, thereby ensuring the sealing of the outer sash 2.
