Abstract

A movable water mist fire protection curtain mainly comprises a slide track and a water supply unit, wherein a plurality of sliding parts are arranged in the slide track; the sliding parts can slide along the axial direction of the slide track; at least a flow passage penetrates the sliding parts along the axial direction of the slide track; and the water supply unit comprises a plurality of hoses respectively connected between both sliding parts and a plurality of jet heads respectively arranged on the sliding parts. Therefore, the water supply unit can extend and can be closed together with the sliding of the sliding parts, and the fluid in the water supply unit can form a water mist-shaped water curtain parallel to the slide track through the jet heads.

Description

Portable thin water smoke cuts the fire curtain

Technical field

The utility model is that to cut fire curtain relevant with the thin water smoke of a kind of movable type.

Background technology

The fire prevention design of common buildings, Chang Kejian uses fire wall and fire-retardant folding door made to separate the space, with when fire takes place, to catch fire and separate from preventing fire spreading, for people strive for escape time, but owing to fire wall takes up space, and can influence people's course, so existing fire prevention design is many based on fire-retardant folding door made, only, this fire-retardant folding door made normally is arranged at the passway, therefore for the interior space of big square meter number, and small fire often, also can spread to whole space, and according to statistics, the people in the scene of a fire of losing one's life is engulfed by flame, but sucks too much poisonous dense smoke thereby death by suffocation, especially when fire takes place, the speed of dense smoke diffusion is faster than flame, and all-pervasive, though this fire-retardant folding door made can temporarily be isolated the district that catches fire, but the effect for the obstruct of dense smoke is still limited, in case and after this fire-retardant folding door made expansion, the too late people that escape in the district that catches fire will be caught in and can't flee from, historical facts or anecdotes has necessity of improvement.

The utility model content

The utility model provides the thin water smoke of a kind of movable type and cuts the fire curtain, it mainly is to include a slide rail and a water supply unit, wherein, be provided with a plurality of sliding parts in this slide rail, described sliding part can endwisely slipping along this slide rail, and this slide rail of described sliding part upper edge axially provided at least one runner, and respectively be provided with a junction in the formed runner mouth of this runner, and should include a plurality of flexible pipes and a plurality of shower nozzle in the water supply unit, wherein, described flexible pipe is arranged at respectively between described sliding part, and its two ends are connected on the corresponding connecting portion, is connected into a supply channel that communicates with the runner with described sliding part, and, described shower nozzle then is arranged at respectively on this sliding part, and communicates with this runner, and described shower nozzle is to be provided with at least one dispersive nozzle in the same direction.

The beneficial effects of the utility model are: when usual state, can with should the water supply unit and described shower nozzle collapse in an end of this slide rail, not only comparatively attractive in appearance, and make the utilization of this interior space more flexible, then but rapid deployment surrounds point of origin when fire alarm takes place, and allow the fluid in this water supply unit form the thin water smoke shape water curtain parallel together by described shower nozzle with this slide rail, to stop fire spreading and to prevent that dense smoke from running helter-skelter.

The specific embodiment

Seeing also Figure 1 and Figure 2, is the cutaway view for preferred embodiment of the present utility model, and the thin water smoke of this movable type cuts fire curtain 100 and consists predominantly of a slide rail 10 and a water supply unit 20, wherein:

Be provided with a plurality of sliding parts 11 in this slide rail 10, described sliding part 11 can endwisely slipping along this slide rail 10, in present embodiment, this sliding part 11 is an assembly pulley, it has rectangular without exception body 12, this body 12 respectively is provided with a pair roller 13 in the both sides of minor axis, and can in this slide rail 10, slide, in addition, this body convexes with an extension 14 towards these slide rail 10 outsides, this this slide rail 10 of extension 14 upper edges axially provided a runner 15, and in these 15 formed runner choma weeks of runner, outwards respectively extended to form a junction 16, in present embodiment, this connecting portion 16 is a ring flange by the circumferentially outer extension setting of this runner choma.

This water supply unit 20 includes a plurality of flexible pipes 21 and a plurality of shower nozzle 22, wherein, described flexible pipe 21 is arranged at 11 of described sliding parts respectively, and its two ends are connected on the corresponding connecting portion 16, be concatenated into a supply channel that communicates with runner 15 with described sliding

part

11, and, 22 in described shower nozzle is arranged at respectively on the extension 14 of this sliding part 11, and communicate with this runner 15, and please consult shown in Figure 3 simultaneously, described shower nozzle 22 is provided with a dispersive nozzle 23 in the same direction, and the optimum shape of this dispersive nozzle 23 is an in-line, and the axially parallel setting of this dispersive nozzle 23 and this slide rail 11.

See also Fig. 4 and shown in Figure 5, be to be action schematic diagram of the present utility model, the thin water smoke of this movable type cuts fire curtain 100 and is arranged on the ceiling 200 of an interior space, and can be according to the fire control plan of this interior space, utilize this slide rail 10 that this interior space is divided into a plurality of fire compartments, in present embodiment, this slide rail 10 is to adopt the cross setting, so that this interior space is distinguished into the quartering, thus, under usual state, this water supply unit 20 is ends that collapse in this slide rail 10 by described sliding part 11, so not only comparatively attractive in appearance, and can allow the utilization of this interior space more flexible, and, when fire alarm takes place, as shown in Figure 5, this water supply unit 20 will be with the described sliding part 11 quick expansion that endwisely slip along this slide rail 10, form one L shaped to surround point of origin, and suitably adjust the position and the quantity of this shower nozzle 20, allow water in this water supply unit 20 by these shower nozzle 22 ejections, constitute together the thin water smoke shape water curtain parallel, to stop fire spreading and to prevent that dense smoke from running helter-skelter with this slide rail 10, simultaneously, because the dispersive nozzle 23 of this shower nozzle 22 is to be in-line as shown in Figure 3, so thin water smoke can be concentrated on the plane, and can effectively reduce the dead angle of this water curtain, in addition, water in this water supply unit 20 more can add extinguishing chemical, except that can increasing the fire extinguishing effect, in the time of can avoiding oil fire takes place simultaneously, because the proportion of oil is lighter than water, cause intensity of a fire diffusion, or when appliance fire takes place, because outage unexpected generation such as cause that personnel get an electric shock.
