Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the present invention is not limited thereto.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "provided," "connected," and the like, may be specifically understood by those skilled in the art. Furthermore, the terms "upper", "lower", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1 to 5, the specific implementation process of the present invention is as follows:

an electric control outward-opening lower-suspension smoke exhaust window comprises a window frame 4, a window sash 5, an air supporting limiting device 6, an electric lock 7, a lower-suspension hinge 8 and a fireproof cable 9. The window further comprises a smoke alarm device, and the smoke alarm device is arranged on the inner side of the window sash 5. When the smoke exhaust window is failed and cannot be opened, if the smoke concentration in the air reaches a preset threshold value, an alarm is triggered, and the safety is improved.

The window sash 5 and the window frame 4 are standard aluminum alloy external opening sash standard frames and panels to form a main structure of the fire and smoke exhaust window, the window frame 4 is fixedly connected between the upright posts 1 and the cross beams 2 of the external vertical surface of the building, the window sash 5 is installed in the window frame 4, and glass 3 is arranged in the window sash 5. The opening direction of the window sash 5 is towards the outside of the building.

The window sash 5 is also provided with a handle and a lock catch, so that the window sash 5 can be operated manually. The specific distribution can be adjusted and distributed according to actual requirements by referring to the arrangement rule of the multipoint locks. The window sash 5 is rotatably connected with the window frame 4 through a lower suspension hinge 8. The air supporting limiting device 6 comprises a pushing cylinder and a limiting pull rod and is connected between the window frame 4 and the window sash 5, and the air supporting limiting device 6 is connected with the electric lock 7 through a fireproof cable 9. The specific installation position and the limiting width of the gas strut limiting device 6 are arranged according to design requirements, and the device meets the requirements of tensile force bearing and gas strut thrust.

The air supporting limiting device 6 is started after receiving an electric signal instruction of the electric lock 7, the window sash 5 outwards revolves and turns over the lower suspension hinge 8 under the thrust action of the pushing cylinder, and the window sash stops after being restrained by the limiting pull rod. At the moment, the smoke exhaust window is opened, and the opening is upward, so that the functional requirements of fire protection and smoke exhaust are met.

The electric lock 7 controls the gas supporting and limiting device 6 to be started and closed. The switch electrically connected with the periphery of the electric lock 7 is arranged on the wall for convenient operation.

In particular, a dust discharging hole is arranged below the window frame 4. Based on the working environment of the smoke exhaust window, a large amount of dust is easily accumulated in the gap of the window frame 4 of the smoke exhaust window, and the smoke exhaust window is difficult to clean. The dust discharging hole is formed below the window frame 4, so that dust accumulated in the gap of the window frame 4 can be discharged and cleaned in time.

The general outward-opening bottom-hung window also needs to be provided with a limit support and a locking device, such as a multipoint lock, a handle and the like. Manual operation is required and should be installed at a higher position according to the safety specification of the fire window. The operating handle of the top-hung window is arranged at the upper part of the opening sash and is higher, so that the operating handle is difficult to operate in a fire fighting state. The utility model discloses an on the basis of the out-swinging casement window under prior art, add electric control locking and mechanical distraction device to when realizing needing to discharge fume, accept the fire control instruction, open the exhaust window automatically.

The utility model discloses a concrete implementation way does:

when the air supporting limiting device 6 receives a fire-fighting electric signal instruction from the electric lock 7, the window sash 5 is opened by electrifying. The pushing cylinder gives an outward pushing force to the window sash 5 to expand the window sash 5 outwards. The window sash 5 rotates around the lower suspension hinge 8 to be opened, turns outwards and opens the opening sash; the rotation is stopped after being restrained by the limit pull rod. At this time, the smoke discharge window is opened. And the electric lock 7 is operated to contract the pushing cylinder and close the window sash 5.

The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
