Background technology
Line style light beam smoke detector, utilize infrared ray composition detection source, utilize the diffusivity of smog can survey the infrared ray fire within fixed range around, line style light beam smoke detector is normally composed of by infrared illuminator that be installed separately, through harmonizing and light receiving device; Its principle of work is to utilize cigarette to reduce the light beam light quantity rice that infrared illuminator is transmitted into infrared light receiving device to judge fire, and this fire detecting method is often referred to as cigarette dim light method, and infrared beam smoke detector is divided into again two kinds of correlation type and reflection-types.
Because the installation site of smoke detector is changeable, and installation environment complexity causes smoke detector cisco unity malfunction, and the normal work of fire alarm system is caused to very large hidden danger.Linear infrared beam smoke sensing detector light damping plate, diffusivity that can simulation smoke can be surveyed the infrared ray fire within fixed range around, its principle of work is that the light beam light quantity rice that utilizes light damping plate minimizing infrared illuminator to be transmitted into infrared light receiving device is judged fire, and this fire detecting method is often referred to as dim light method.
But existing linear infrared beam smoke sensing detector light damping plate, has the following disadvantages:
1, extendible length is shorter, and during detection, operating personnel also need to use ladder can carry out testing, and it is not good enough to detect the dirigibility in when operation, can make testing become more complicated, affects detection efficiency;
2, the outer rim of light damping plate does not have protective device, can make light damping plate easily damaged in use, has a strong impact on the serviceable life of light damping plate.
Utility model content
For above-mentioned technical matters, the utility model provides a kind of infrared fire detection device light damping plate that can reduction, this apparatus structure is simple, practical, and dirigibility during operation is large, the ladder that do not need to arrange in pairs or groups just can be carried out testing, can make testing convenient, fast, applicable to multiple special occasion, and the outer rim of light damping plate is provided with protective device, can effectively prevent that light damping plate is damaged in use, extend the serviceable life of light damping plate.
For solving the problems of the technologies described above, the utility model provides a kind of infrared fire detection device light damping plate that can reduction, comprise expansion link, light damping plate, light damping plate clip, light damping plate mounting groove, wherein the top of expansion link is provided with light damping plate clip, the middle part of light damping plate clip is provided with light damping plate mounting groove, in light damping plate mounting groove, light damping plate is installed.
As further improvement of the utility model, for the steadiness that guarantees that light damping plate is installed, on light damping plate clip, be provided with clip button, light damping plate is fixed on expansion link again by clip button.
As further improvement of the utility model, when guaranteeing that light damping plate detects in particular surroundings adaptability, the bottom of expansion link is provided with elongated hole again.
As further improvement of the utility model, for the steadiness that guarantees that light damping plate is installed, between light damping plate mounting groove and light damping plate, be provided with anti-skidding firm layer.
As further improvement of the utility model, while detecting operation in order to increase, the frictional behaviour of expansion link, prevents from skidding, and on the outside surface of expansion link bottom, is provided with skid resistant course.
As further improvement of the utility model, in order to increase the serviceable life of light damping plate, the outer rim of light damping plate is provided with light damping plate and protects edge.
