Embodiment 1

[0039] The invention discloses an electric smoke-shielding vertical wall 1 device, such as figure 1 and figure 2 As shown, it includes the main body of the smoke retaining wall and the release part of the smoke retaining wall; the main body of the smoke retaining wall is embedded in the ceiling 4, the main body of the smoke retaining wall is provided with a movable end and a fixed end, and the fixed end is rotatably connected with the ceiling 4 through the rotating shaft 3 ; The movable end is provided with a warning device; the smoke-shielding vertical wall release part is arranged on the ceiling 4; the smoke-shielding vertical wall release part can fix and release the movable end of the smoke-shielding vertical wall main body.

[0040] Specifically, the electric smoke baffle 1 device of the present invention includes a square smoke baffle main body and a smoke baffle releasing part; wherein, the suspended ceiling 4 is provided with a groove, and the smoke baffle main body i...

Embodiment 2

[0055] This embodiment is on the basis of embodiment 1, as image 3 and Figure 4 As shown, considering that the monitoring unit 8, the monitoring host of the electric smoke screen 1, the fire information sensor and other equipment may fail, the remote release of the main body 1 of the electric smoke screen 1 cannot be realized, and the overall power failure of the building may also occur. If it is not timely, a manual release button 5 and a baffle 11 can be provided; the manual release button 5 controls the power-off of the electromagnetic release 2, and the manual release can make the baffle 11 move so that the movable end of the smoke-shielding wall rotates downward around the shaft 3 drooping.

[0056] Specifically, the electromagnetic releaser 2 is connected to the baffle plate 11 through a spring, and the spring is usually attracted by the electromagnetic releaser 2 and is in a stretched state; then the electromagnetic releaser 2 releases the main body of the electric s...

Embodiment 3

[0059] Such as Figure 5 As shown, on the basis of Embodiment 1 and Embodiment 2, the electric smoke-blocking wall 1 device of this embodiment includes a plurality of smoke-blocking walls, wherein the smoke-blocking wall is close to one side of the wall. A second sealing part is arranged on the side, and when the vertical smoke-shielding wall rotates and hangs down, the second sealing part is used to prevent smoke from leaking in the gap between the vertical smoke-shielding wall and the wall.

[0060] The above-mentioned first sealing part is a magnetic suction sealing strip, for example, a fixed magnetic suction sealing strip 12, and the magnetic suction sealing strip is arranged on both sides of the main body of the electric smoke-shielding vertical wall 1 (that is, the side of the smoke-shielding vertical wall close to the wall) side); the side where the magnetic edge banding is connected to the main body of the electric smoke-blocking vertical wall 1 is provided with a mag...

Abstract

The invention relates to an electric smoke-retaining wall device and a smoke-retaining method, which belong to the technical field of smoke-retaining walls, and solve the problems that the existing smoke-retaining wall devices occupy a large space, have complicated lifting structures and high costs, and cannot guarantee normal lowering of the baffle in case of fire. Technical problem with smoke hanging wall. The electric smoke baffle device includes a smoke baffle main body and a smoke baffle releasing part; the smoke baffle main body is embedded in the ceiling, the smoke baffle main body is provided with a movable end and a fixed end, and the fixed end is rotatably connected to the ceiling through a rotating shaft; The movable end is provided with a warning device; the smoke-shielding vertical wall release part is arranged on the ceiling; the smoke-shielding vertical wall releasing part can fix and release the movable end of the smoke-shielding vertical wall main body. The invention not only occupies a small space, but also ensures the safety when a fire occurs.

Description

technical field [0001] The invention relates to the technical field of smoke-shielding vertical walls, in particular to an electric smoke-shielding vertical wall device and a smoke-shielding method. Background technique [0002] The smoke-blocking vertical wall is made of non-combustible materials and installed under the ceiling, beam or ceiling of the building. It can form a certain smoke-storage space in the event of a fire. Horizontal diffusion under the beam or ceiling, and constrain it in a specific area, so that the smoke can be discharged through the smoke exhaust facilities in this area in time. The smoke-blocking wall is divided into fixed smoke-blocking wall and electric smoke-blocking wall; the fixed smoke-blocking wall is generally not less than 500mm high, and is installed under the ceiling, beam or ceiling. Since the fixed smoke-blocking wall is a fixed structure and takes up a lot of height, it affects the clear height and appearance of the building, especial...
