As shown in fig. 5, further, the lifting mechanism 002 is disposed outside the smoke outlet 200, and includes a fixed column 1 and a lifting column 2 from bottom to top, wherein the fixed column 1 is vertically installed on the building beside the smoke outlet 200, and the lifting column 2 is movably connected to the fixed column 1, and the fixed column 1 and the lifting column can move up and down relatively. The upper end of the lifting column 2 is connected to the lower surface of the window body 001, supports the window body 001 and provides the window body 001 to drive the window body 001 to move up and down with an upward acting force.

Preferably, the spout is equipped with in the middle of the lifting column of liftable, and 2 covers of lifting column are established at fore-and-aft fixed column outsidely, and the fixed column holds in the spout, and the lifting column reciprocates in order to change the relative position of lifting column and fixed column through the spout.

Preferably, a driving assembly 3 for driving the lifting column 2 to move is arranged between the lifting column 2 and the fixed column 1. The drive assembly 3 provides an upward force to the lifting ram 2 at all times. When the downward acting force of the traction mechanism 003 is reduced or removed, the upward acting force of the lifting mechanism 002 is larger than the self weight of the window 001 to drive the lifting column 2 to move upwards.

The driving assembly 3 may be a counterweight assembly connected between the fixed column 1 and the lifting column 2, or may be a counterweight assembly.

As shown in fig. 5, specifically, the counterweight assembly includes a counterweight 31, a lifting rope 32 and a fixed pulley 33, one end of the lifting rope 32 is fixed on the lifting column 2 below the fixed pulley 33, the lifting rope 32 is suspended downward after passing upward around the fixed pulley 33, and the lower end thereof is connected with a counterweight 31. Because of the dead weight of the counter weight block 31, the lifting rope 32 is tightened, and the lifting rope 32 always gives an upward acting force to the lifting column 2, so that the lifting column 2 keeps an upward moving situation, and an upward acting force is always applied to the window body 001.

As shown in fig. 6, the fixed pulley 33 includes a first fixed pulley 33a and a second fixed pulley 33b arranged side by side in the lateral direction, the first fixed pulley 33a and the second fixed pulley 33b are mounted on the lifting column 2 by a pulley fixing frame H, one end of the lifting rope 32 is fixed below the first fixed pulley 33a, and the lifting rope 32 is passed over the first fixed pulley 33a in the upward direction, passed over the second fixed pulley 33b in the lateral direction, and suspended downward.

Through setting up second fixed pulley 33b, can transversely expand lifting rope 32, avoid balancing weight 31 contact fixed column 1 or lifting column 2 and lead to the atress to change to guaranteed the stability of window body 001 atress, also ensured the reliability that window body 001 opened and closed state.

As shown in fig. 1 and 5, in the present embodiment, the traction mechanism 003 includes a traction rope 4 and a winding device 5; the winding device 5 is arranged below the window body 001, one end of the traction rope 4 is connected to the window body 001, and the other end of the traction rope is wound on the winding device 5. The winding device 5 realizes the winding and unwinding of the traction rope 4, so that the window body 001 is lifted up and down.

As shown in fig. 7, the pulling mechanism 003 may be driven manually or mechanically. When the window body is driven mechanically, the traction mechanism 003 further comprises a driving part 6, the driving part 6 is a motor, the motor drives the winding part 51 of the winding device 5 to rotate, and the winding device 5 is controlled to wind and unwind the traction rope 4, so that the effect of the traction mechanism 003 on the position of the window body 001 is realized. Preferably, the driving means 6 further comprises a brake for decelerating, stopping or keeping the winding device stopped. And the brake is also provided with a manual operating handle, so that the brake can be manually opened under the condition of power failure to release the action of the brake on the wire coiling device.

Further preferably, the actuator is in communication with an indoor or outdoor fire alarm system of the building, and when the fire alarm system detects a fire, the fire alarm system sends a signal to the actuator, and the actuator receives the signal and then starts the driving part 6, thereby opening the smoke exhaust window.

In the implementation use, when daily weather is good, the user can open the smoke vent and play the effect of ventilation. At this moment, the coiling device 5 is driven by the driving mechanism to gradually release the traction rope 4, thereby the acting force of the traction rope 4 on the window body 001 is reduced, the upward acting force of the lifting column 2 is larger than the resultant force of the self weight of the window body 001 at this moment, so that the lifting column 2 can move upwards, in the process, the counterweight block 31 moves downwards, the lifting column 2 is driven to move upwards, the window body 001 is far away from the opening of the smoke outlet 200, the smoke outlet 200 is opened until the lifting column 2 reaches the upper limit position, the brake stops the rotation of the coiling device, and each component keeps the balance of force to stably keep the window body 001 at a fixed position

When rainy weather, in order to prevent that the rainwater from getting into the building through exhaust port 200, pull rope 4 is retrieved to coiling device 5 this moment, and pull rope 4 tightens and provides the effort downwards to

window body

001, and 4 effort downwards of pull rope and the resultant force of window body 001 dead weight are greater than the effort that makes progress of lifting column 2 to make window body 001 pull the decline gradually, lifting mechanism 002's lifting column 2 is 1 displacement downwards relatively, and the balancing weight is pulled upwards. When the lifting column 2 is positioned at the lower limit position relative to the fixed column 1, the upward acting force of the lifting column 2 is smaller than the resultant force of the downward acting force of the traction rope 4 and the self-weight of the window body 001, so that the window body 001 is pressed on the smoke outlet 200, and the smoke outlet 200 is closed.

In an emergency state, the actuator receives the fire alarm system, so that the driving part 6 releases the traction rope 4, and the lifting mechanism 002 lifts the window body 001 to open the smoke outlet 200.

When in emergency or in fire power failure and the failure of the alarm system, a user can open the brake by manually operating the handle, so that the winding device is in a free state to release the traction rope 4, the acting force of the winding device on the window body 001 is removed, the acting force of the lifting mechanism 002 is greater than the self weight of the window body 001 to enable the window body 001 to rapidly move upwards, the smoke outlet 200 is rapidly and completely opened, and the safety of the fire protection system is further improved.

It should be noted that in the present embodiment, the shape of the window 001, the number of the lifting mechanisms 002 and the pulling mechanisms 003, and the specific installation position are not limited. The number of the lifting mechanism 002 or the traction mechanism 003 may be only one or plural.
