Description
Technical field
The present invention relates to a kind of structures of smoke detector, adjust it by two adjustment screws and two elastic parts
Horizontal position when being set to the smoke detector on wall or ceiling, reaches horizontally disposed function.
Background technique
With the development of science and technology, building is constantly built, the structure of Building Fire Fighting System also progresses greatly many, and fire alarm system
Structure it is also more flexible more diversified, especially as the development of communication software, fire alarm system more combines network to release intelligent system
The function of system and central monitoring, fire alarm system will develop towards intelligent system at present.
The sensing of alarm device is according to that can be divided into four kinds when fire, and the first fire is usually along with cigarette, flame, high temperature and burning
Later the gas generated, so these are usually foundation whether bringing measurement and judge on fire.Second Initial Stage of Fire is in yin
The state of burning, typical temperature is not high but along with a large amount of smog, and inductosyn detects fire with this feature.Third fire
The calamity middle and later periods, along with high temperature and flame, flame sensor and temperature sensor are exactly that fire alarm is made with this feature.The
Four prevent in advance from fire reason on fire and medium, such as gas and natural gas etc. are likely to result in the flammable of fire generation
Property gas go to detect, further fire preventing occurs.
The type of general fire detector there are many kind, be broadly divided into detect warm formula fire detector, detect cigarette formula detector,
Flame-type detector, combustible gas probe and combined type fire detector, wherein detecing warm formula fire detector can be divided into again
Point-type and two kinds of detectors of line style, and point-type and line style are subdivided into temp.-determined type, differential type and differential temp.-determined type respectively again and detect
Device, it is similar to warm formula fire detector is detectd to detect cigarette formula detector, is divided into the detector of point-type and line style, point detector is again
It is divided into that ionic formula detects smoke detector and photo-electric detects two kinds of smoke detector, line style detector is divided into laser again to be detectd with separate type photoelectricity
Two kinds of smoke detector, flame-type detector is then divided into two kinds of detectors of ultraviolet light (UV) and infrared light (IR).
It is at present to detect cigarette formula detector mostly on the market, detects smoke detector and issued by the perception fire of cigarette caused by fire
The alarm device of alarm can be subdivided into ionic formula (ionization type) and two kinds of photo-electric, and wherein ion type smog sensor internal has electricity
From chamber and americium -241, ionization chamber can connect generating positive and negative voltage.Americium -241 can generate Alpha's atom, they can be in ionized air
Nitrogen and oxygen atom, when oxygen or nitrogen-atoms are electrolyzed to produce cation and electronics, cation can be attracted by the ionization chamber of negative voltage at this time,
Anion is then attracted by the ionization chamber of positive voltage, and through the mobile generation electric current of negative ions, when there is smog in air, oxygen is dense
Degree can decline, and electric current can also decline, and be directed to the cigarette characteristic of subrange, generate the principle of ionic current variation, empty when around
Gas acts when reaching a certain concentration or more containing smoke, and photoelectric smoke sensor side uses optical sensor, and there are one light sources
With sensor at 90 degree of angles, light directs out injection when usually without light source, when smog enters smoke sensor device
When internal, light reflexes to sensor by the particle fraction of smog, thus generates alarm, and in other words photo-electric smog senses
Device generates the principle of photoelectricity sub-prime light income variation according to smog characteristic and acts, advantage be will not because light is occluded and
Malfunction is generated, and sensing has the fire effect of cigarette relatively good.Detecing cigarette formula detector indoors can be compared in fire generating process
Sense Bolometer is effectively mended earlier grasps fire signal, is to be currently used in general indoor spaces or shelter, therefore detect cigarette formula
Detector is highly effective for fire alarm early period, using also most extensive.
However smoke sensor device of the invention is invented for photoelectric smoke sensor, photo-electric on the market now
Smoke sensor device is mounted to mostly on wall or ceiling, but does not have the function of level correction, photo-electric smog sensing
Device will often occur judging by accident or sensing less than reflected infrared ray during sensing smog, or during by dress,
The set relative position of the photoelectric smoke sensor main body and reflecting plate is incorrect, causes sensing effect not as expected,
And it can not be sounded an alarm in real time when fire being caused to occur.
In the structure of smoke sensor device in summary, there are many imperfect to the greatest extent structures, therefore the present inventor is through too long
The research and invention of phase invents a kind of structure for detecing smoke detector, internal to have multidirectional adjustment structure, and positioning dress
It sets, when this, which detects smoke detector, is installed in wall or ceiling, can accurately be adjusted to position opposite with reflector plate
Horizontalization row, enable its infrared sensing device accurately issue infrared ray and by reflector plate reflect the infrared ray to this detect cigarette visit
Survey the receiving unit of device, the case where making it judge whether there is fire generation.
Summary of the invention
The main object of the present invention is that providing one kind detects smoke detector structure, internal to have two adjustment structures, by
This can be detectd smoke detector and is installed on wall or ceiling by the adjustment structure is adjusted its horizontal position, makes reflecting plate phase
When detecing smoke detector for this, this, which detects smoke detector, can adjust position relative to the reflecting plate, this is made to detect smoke detector
The infrared ray that infrared ray emission part is emitted accurately can detect the red of smoke detector to this by the baffle reflection infrared ray
Outside line receiving unit keeps the function of detecing smoke detector detecting smog sensitiveer.
It is another object of the present invention to provide one kind to detect smoke detector structure, internal to have a positioning device, sets
This is placed in detect between the infrared ray emission part of smoke detector and infrared receiver portion, which is a laser positioning device,
This is detectd after smoke detector is set on wall or ceiling, by its internal laser be set to device emit a laser to relative to
After this detects the reflecting plate of smoke detector, the reflected position of the laser light is identical as the transmitting position of laser, then represents its peace
Set position completion.
