Description

Independent smoke-sensing automatic window opening device

Technical Field

The utility model belongs to the technical field of automatic window opening devices, and particularly relates to an independent smoke sensing automatic window opening device.

Background

According to american fire protection association statistics, the main causes of death of personnel in fires are choking and smoke poisoning, of which about 80% originate from toxic smoke, 13% originate from high temperatures, and 7% are other causes. The modern buildings inevitably use a large amount of inflammable and combustible decoration materials due to functional requirements, and once a fire disaster occurs, the materials can decompose and release combustible steam in a short time after encountering flame bombardment or high-temperature roasting, a large amount of heat and smoke are generated by combustion, the progress of fire disaster development is rapidly promoted by accumulating a large amount of heat indoors, the detonation occurrence time is shortened, and a large amount of toxic gases are released by combustion, so that serious threat is brought to personnel evacuation and fire-fighting rescue. When a fire disaster occurs in a building room, in order to prevent the casualties caused by the toxicity of the smoke, the temperature of a fire scene is reduced, and the window is opened as soon as possible, smoke is discharged, and the temperature is reduced.

The fire smoke contains a large amount of carbon monoxide, carbon dioxide, hydrogen fluoride, hydrogen chloride and other toxic components, and the high temperature and oxygen deficiency of the fire scene can cause great harm to human bodies. The smoke gas is removed in time, and the smoke gas fire extinguishing device has very important effects of ensuring personnel to safely evacuate and controlling smoke gas to spread and extinguishing fire in time. When a certain part of the building is on fire, effective smoke discharging measures are adopted to remove smoke and heat generated by the combustion of combustible substances, so that a relative negative pressure area is formed in the local space; smoke prevention measures should be taken for non-ignition parts, evacuation channels and the like to prevent smoke from invading, so that people can be evacuated and the fire can be extinguished and rescued, and therefore, smoke exhausting facilities are necessary to be arranged in the building.

The national standard GB50016-2014 provides clear smoke discharging requirements for public buildings, civil buildings, industrial plants and warehouses. According to the national standard 'fireproof valve for building ventilation and smoke exhaust system' GB/T15930-2007 is revised to 'fireproof valve for building ventilation and smoke exhaust system and smoke exhaust window' GB/T15930-20 XX, the product standard and the setting requirement of the smoke exhaust window are increased, the smoke exhaust window is defined to be arranged on the top or the outer wall of a smoke exhaust area of a building, and the window sash can be opened manually or under the control of a fire automatic alarm system during fire, so that smoke and hot air are exhausted from a room in a natural ventilation mode. The new revised national standard GB50016 "building design fire protection Specification" will also correspondingly increase the range of settings and applications for smoke evacuation windows in building designs, particularly civil building designs.

The traditional smoke window setting is that the electric smoke window is linked by using a fire automatic alarm system, the fire automatic alarm system detects a fire alarm signal when firing, then the fire control center is fed back, the remote opening and closing functions of the window are realized by the fire control center manually or automatically through a central control box equipped with the smoke window, a smoke induction detector, a 72-hour uninterrupted backup power supply and an emergency button are generally also equipped, and the opening and closing of the window are generally realized by installing a chain type electric opening actuator or a hydraulic rod actuator on a window frame and pulling or hydraulically stretching the window sash through double chains. This kind of setting scheme needs a large amount of wiring and processing module, and installation use maintenance cost is very high, and external chain or hydraulic stem influence window pleasing to the eye and normal use function (if the volume influences the sight greatly, external apparent dress leads to unable installation screen window, rain easily rust, the part is heavier has safe fall risk etc.), and the daily use of opening and ventilation function of window can't be realized to the fume extraction window.

1. the sliding block is connected with the thermosensitive blocking mechanism which is used for being clamped into the sliding way, so that when smoke appears in a room, the smoke detector can sense, and the relay is electrified. The relay enables the on-off state of the thermosensitive blocking mechanism to be changed, so that the thermosensitive blocking mechanism can lose the effect of being clamped with the slide way under the thermosensitive effect, and at the moment, the slide block can slide in the slide way freely. The other end of the telescopic arm is connected with a return mechanism, when the thermosensitive blocking mechanism fails, the return mechanism drives the telescopic arm to rotate, the telescopic arm drives the sliding block to slide in the slideway, and the telescopic arm opens the window sash, so that automatic window opening is realized when smoke appears.

And when the window is normally used, the telescopic arm can be telescopic, so that the window sash can be manually opened and closed, and the normal use of the window is not affected.

2. The heat sensitive element is a hot melt bead, when the smoke detector detects smoke, the normally open contact of the relay is closed, and the heating resistance wire heats, so that the hot melt bead is heated by the heating resistance wire and is exploded. At this time, the stop block falls from the blocking groove due to the loss of the support of the hot melt beads, and at this time, the sliding block can freely slide in the sliding groove. Therefore, when smog appears, the thermosensitive blocking mechanism can fail in time, the restoring mechanism is guaranteed to drive the telescopic boom to rotate, then the sliding block moves in the slideway, and the window sashes are unfolded by the telescopic boom, so that the response speed is high.

The heating resistance wire is electrified and heats, so that the thermosensitive polymer damping block is heated and expanded, and is always clamped in the slideway. When the smoke detector detects smoke, the normally closed contact of the relay is disconnected, the heating resistance wire is powered off and cooled, the friction force between the thermosensitive polymer damping block and the slideway is reduced, and the sliding block can move freely in the slideway. When smoke appears, the utility model can timely detect the smoke and lead the thermosensitive blocking mechanism to fail in time, thereby ensuring that the restoring mechanism drives the telescopic arm to rotate, then the sliding block moves in the slideway, and the window sash is propped by the telescopic arm, so as to realize automatic window opening.

5. When the window is normally used, the window sash can be pushed and pulled to a certain opening and closing degree, and the sliding head on the connecting rod slides in the sliding groove of the telescopic rod for a certain distance. When the sliding window sash stops being slid, the window sash can be positioned due to a certain damping force between the sliding head and the sliding groove. Therefore, when no smoke appears, the utility model can not influence the normal opening and closing of the window, and the use is more convenient.

6. The torsional spring has certain restoring force for the pivot has the trend of drive telescopic boom rotation all the time. When the sliding block can automatically move in the slideway, one end of the telescopic arm, which is far away from the restoring mechanism, can freely move, and the torsion spring immediately drives the telescopic arm to rotate through the rotating shaft, so that the aim of automatically opening the window sash in time is fulfilled, and the window sash is reliable to use.
