Abstract
The utility model relates to a kind of sensor fixing structure for smoke alarm obstacle detection system, and it comprises base, outer cover, some to sensor, plasticity cage ring; Described sensor is made up of infrared transmitter and receiver, plasticity cage ring outer rim is evenly equipped with the individual cells mount pad with sensor respective amount, somely be staggered on mount pad to infrared transmitter and receiver, the position covering on corresponding infrared transmitter and receiver is outward provided with through hole, described base is fixed on buildings wall, plasticity cage ring is fixed on base, outer cover covers in plasticity cage ring, and infrared transmitter and receiver are launched by the through hole of outer cover or received infrared light.Advantage of the present utility model: when there being enough large object to enter in sensing range, in a sense cycle, alarm can detect the existence of barrier, thus produces relevant early warning, and prompting related personnel removes barrier, guarantees the unimpeded of smoke path.
Description
technical field:
The utility model relates to a kind of signalling or calling device, warning device, especially relates to a kind of sensor fixing structure for smoke alarm obstacle detection system.
background technology:
In prior art; smoke alarm is reported to the police mainly for smog; when some furniture or equipment etc. often can be placed on the passage blocking smog circulation detection close to alarm, thus when fire produces, alarm can not detect smog in time and delay time of fire alarming.The present inventor proposes and have developed the function that can periodically can detect surrounding environment and monitor again at generation smog alarm, when one amount has enough large object to enter in sensing range, alarm can detect the existence of barrier, thus produce relevant early warning, prompting related personnel removes barrier, guarantees the unimpeded of smoke path.
summary of the invention:
The purpose of this utility model be provide for prior art weak point a kind of structure simple, guarantee the sensor fixing structure for smoke alarm obstacle detection system that smoke path is unimpeded.
The purpose of this utility model is realized by following measures: a kind of sensor fixing structure for smoke alarm obstacle detection system, and it comprises base, outer cover, it is characterized in that, also has some to sensor, plasticity cage ring; Described sensor is made up of infrared transmitter and receiver, plasticity cage ring outer rim is evenly equipped with the individual cells mount pad with sensor respective amount, somely be staggered on mount pad to infrared transmitter and receiver, the position covering on corresponding infrared transmitter and receiver is outward provided with through hole, described base is fixed on buildings wall, plasticity cage ring is fixed on base, outer cover covers in plasticity cage ring, and infrared transmitter and receiver are launched by the through hole of outer cover or received infrared light.
The base plane of described mount pad and horizontal angle are 130 degree.
It is four right that described sensor is provided with.
Compared with prior art, have employed a kind of sensor fixing structure for smoke alarm obstacle detection system that the utility model proposes, tool has the following advantages: this product has had to surrounding environment the function detecting and monitor, when there being enough large object to enter in sensing range, in a sense cycle, alarm can detect the existence of barrier, thus produces relevant early warning, prompting related personnel removes barrier, guarantees the unimpeded of smoke path.
accompanying drawing illustrates:
Fig. 1 is the embodiment sensor mounting plane schematic diagram that the utility model proposes;
Fig. 2 is Fig. 1 embodiment A-A diagrammatic cross-section;
Fig. 3 is Fig. 1 Embodiment B-B diagrammatic cross-section.
embodiment:
Below in conjunction with accompanying drawing, embodiment is elaborated: Fig. 1 ~ Fig. 3 shows an embodiment of the present utility model.In figure, a kind of sensor fixing structure for smoke alarm obstacle detection system, it comprises base 1, outer cover 2, some to sensor, plasticity cage ring 4; Described sensor is made up of infrared transmitter 31 and receiver 32, plasticity cage ring 4 outer rim is evenly equipped with individual cells 41 mount pad with sensor respective amount, somely be staggered on mount pad to infrared transmitter 31 and receiver 32, outer cover 2 is provided with through hole 21 on the position of corresponding infrared transmitter 31 and receiver 32, described base 1 is fixed on buildings wall, plasticity cage ring 4 is fixed on base, outer cover 2 covers in plasticity cage ring 4, and infrared transmitter 31 and receiver 32 are launched by the through hole 21 of outer cover 2 or received infrared light.In this structure, the individual cells mount pad of plasticity cage ring outer rim is provided with four to staggered infrared transmitter and receiver, sends infrared light by transmitter, infrared light, after the barrier reflection around alarm, will be received by receiver.Send information early warning when receiver receives signal, prompting related personnel removes barrier.
The utility model takes following measure further: the base plane of described mount pad and horizontal angle are 130 degree.The scope that the light that such angle sensor installation can make the transmitter of sensor give out covers is maximum, is also convenient to receive.
The embodiment provided above does not form restriction of the present utility model, and in this area, those skilled in the art make various distortion within the scope of the appended claims or revise all in protection domain.
