Description

Technical Field

[0001] The present application relates to the technical field of smoke barrier vertical walls, and in particular to a movable flexible smoke barrier vertical wall. Background Art

[0002] Since the establishment of the Ministry of Emergency Management, the country has attached more and more importance to fire safety. Especially large shopping malls, office buildings, warehouses, etc. must be equipped with a variety of fire-fighting equipment. Smoke barriers are one of the main fire-fighting equipment and are suitable for large shopping malls, office buildings, and warehouses. In particular, large shopping malls have many shops and need to use smoke barriers to block smoke and form smoke separation areas. The fireproof cloth of the smoke barrier is made of non-combustible material. The smoke barrier is divided into movable and fixed types according to the method of use. The movable smoke barrier refers to the smoke barrier that automatically droops due to the action of temperature, smoke or other control equipment during a fire. It is mainly used in high-rise or super-high-rise large shopping malls, office buildings, warehouses and other occasions. It can effectively block the horizontal flow of smoke under the ceiling of the building, so as to improve the smoke exhaust effect in the smoke-proof partition, and play a certain role in protecting people’s lives and property.

[0003] The smoke barrier wall is made of non-combustible materials and installed under the building ceiling, beams or suspended ceiling. It is a smoke barrier separation facility that can form a certain smoke storage space in the event of a fire. Its main function is to block the lateral diffusion of smoke under the building ceiling, beams or suspended ceiling in the event of a fire, and confine it to a specific area so that the smoke can be discharged in time through the smoke exhaust facilities in the area. The current smoke barrier walls are relatively simple, with insufficient flame retardant effect, and it is easy for smoke to enter the protection box, causing damage to the smoke barrier wall and affecting the smoke barrier effect of the wall. Therefore, in order to solve the above problems, we provide a movable flexible smoke barrier wall. Utility Model Content

[0004] The purpose of the utility model is to provide a movable flexible smoke barrier vertical wall to solve the problems raised in the above background technology.

[0005] The present application embodiment adopts the following technical solutions:

[0006] A movable flexible smoke barrier vertical wall comprises a protection box, a through groove is provided on the bottom surface of the protection box, a protection cover is fixedly connected to the inner wall of the protection box, a through hole is provided on the left side of the protection cover, a forward and reverse motor is installed inside the protection cover, a bearing is fixedly inlaid on the inner wall of the protection box, the output end of the forward and reverse motor is fixedly connected to the inner ring of the bearing, a winding wheel is provided on the outer surface of the bearing, a flexible vertical wall is provided on the outer surface of the winding wheel, a fireproof layer is provided on the front side of the flexible vertical wall, a flame retardant layer is provided on the back side of the flexible vertical wall, a counterweight rod is fixedly connected to the bottom end of the flexible vertical wall, a sealing gasket is fixedly connected to the bottom surface of the counterweight rod, and a sealing ring is fixedly connected to the inner wall of the through groove.

[0007] Preferably, the flame retardant layer is a flame retardant polyvinyl chloride layer, and the fireproof layer is a flexible fireproof asbestos layer.

[0008] Preferably, a protective door is hinged on the front of the protective box via a pin, and a safety lock is provided on the front of the protective door.

[0009] Preferably, a handle is fixedly connected to the front of the protective door, and an escape sign is fixedly connected to the front of the protective door.

[0010] Preferably, the inner bottom wall of the protection box is fixedly connected with a support seat, and the upper surface of the support seat is fixedly connected to the inner bottom wall of the protection cover.

[0011] Preferably, the outer surface of the protection box is fixedly connected with symmetrical mounting plates, and mounting holes are provided on the front sides of the two mounting plates.

[0012] At least one of the above technical solutions adopted in the embodiments of the present application can achieve the following beneficial effects:

[0013] The movable flexible smoke barrier wall can increase the flame retardant effect of the flexible vertical wall through the flame retardant layer, and can increase the fireproof performance of the flexible vertical wall by using the fireproof layer. The flexible vertical wall can be dropped by clockwise rotation of the forward and reverse motor, and the cooperation of the counterweight rod and the sealing pad can make the extension of the flexible vertical wall smoother, thereby improving the smoke barrier effect of the flexible vertical wall. The through groove can be sealed by the sealing ring to prevent smoke from entering the interior of the protective box, and the flexible vertical wall can be rolled up by counterclockwise rotation of the forward and reverse motor to improve protection of the flexible vertical wall.
