Embodiment 1

[0013] Refer to attached figure 1 . The utility model comprises a casement window switch power transmission mechanism, a connecting piece 1 and a motor 2 connected with the transmission mechanism and the casement window.

[0014] Motor 2 is controlled by the fire alarm control system.

[0015] The motor transmits power to the transmission mechanism through the reduction mechanism 3 . The reduction mechanism is a reduction gear set. The main body of the reduction gear set is preferably located on the front of the motor. That is to say, the reduction gear set is basically located in the axial projection area A of the motor.

[0016] The transmission mechanism is a chain 4 parallel to the moving direction of the casement window. The reference numeral 5 is the driving sprocket, and the reduction gear set transmits power to the driving sprocket 5 through the bevel gear set.

[0017] The travel limit switch 6 of motor can be provided with respect to the movement limit position...

Embodiment 2

[0020] Refer to attached figure 2 . The transmission mechanism of this embodiment is a transmission screw rod 8 whose rotation axis is parallel to the moving direction of the sliding window. The connecting piece 1 is engaged with the driving screw rod 8 . Others are with embodiment 1.

Abstract

The invention relates to a fire smoke-discharge device. It includes sliding window opening and closing power transmission mechanism, connecting component between transmission mechanism and sliding window and motor. The opening and closing of the sliding window is driven by motor, and said motor can utilize a speed-reducing mechanism to transfer the power to transmission mechanism. Besides, said device also includes the components of speed-reducing gear group, chain, driving guide screw and limit switch, etc.

Description

technical field [0001] The invention relates to a fire alarm and smoke exhaust device, in particular to a fire alarm and smoke exhaust device for windows. Background technique [0002] When a building fire comes, people in the building often first consider how to escape, while ignoring or having no time to perform smoke exhaust self-rescue, and, in large buildings, the number of windows is often huge, and the escapers need to open them one by one. Also unrealistic, like this, the smog in the building can not be dispersed in time and the dangerous situation when the fire alarm comes more aggravated. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fire alarm smoke exhaust device that can provide equipment basis for automatic smoke exhaust when a fire alarm comes. For this reason, the present invention adopts the following technical solutions: it comprises a sliding window switch power transmission mechanism, a c...
