By such scheme, described button is organic glass material button, and elastic body is polyurethane elastomer.
By such scheme, it also comprise for when button is pressed stop button naturally return dial stretch structure.
By such scheme, described dialling is stretched structure and is comprised spring and the ball valve with spring contact, and ball valve contacts with button lip, and the radius of ball valve is greater than the moving displacement of button.
By such scheme, it also comprises for fixing elastomeric base, and described elastic body is arranged on base, and base is provided with the optical fiber fairlead of drawing for optical fiber.
By such scheme, it also comprises retracing spring, and retracing spring is arranged between button and base.
By such scheme, it also comprises retracing spring, and retracing spring is arranged in sliding sleeve, and described top stem casing is in retracing spring.
By such scheme, it also comprises for the protection of elastomeric inner box, and described elastic body is fixed in inner box, and inner box is provided with the through hole passed through for push rod and the optical fiber fairlead of drawing for optical fiber.
The beneficial effects of the utility model are:
1, by adopting the passive elastomeric deformation of fiber grating perception, as warning trigger pip, there is the advantages such as electromagnetism interference, long transmission distance, intrinsic safety, also can use there is no the place of power supply and darkness humidity.Be converted to electric signal through Optical Fiber Transmission again to safety area, thus be applicable to the place that oil, tunnel, natural gas line, chemical industry, metallurgical electric power, storage etc. are strict to electricity requirement and darkness is moist.
2, by adopting retracing spring, this device can be reused, cost-saving.
3, pass through setting group and stretch structure, ensureing reusable while, make cannot naturally reset after button is pressed, needing to adopt specific purpose tool to make push-button reset the rear professional of solution warning threat.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the structural representation of the another embodiment of the utility model.
In figure: 1-shell, 2-button, 3-push rod, 4-retracing spring, 5-dials and stretches structure, 6-fiber grating, 7-elastic body, 8-base, 9-optical fiber, 10-optical fiber fairlead, 11-inner box, 12-sliding sleeve.
Embodiment
Below in conjunction with instantiation and accompanying drawing, the utility model is described further.
embodiment one:
The structural representation of Fig. 1 the utility model one embodiment, comprise shell 1, shell 1 is provided with button 2, button 2 is connected with the flip flop equipment in shell 1, wherein flip flop equipment comprises elastic body 7, elastic body 7 is fixed with fiber grating 6, the optical fiber 9 be connected with fiber grating 6 draws shell 1 as signal output part; Button 2 to be contacted with elastic body 7 by push rod 3 and makes elastic body 3 that deformation occur, thus the centre wavelength causing fiber grating to reflect changes, and produces trigger pip.
It also comprises for fixing elastomeric base 8, and described elastic body 7 is arranged on base 8, and base 8 is provided with the optical fiber fairlead 10 of drawing for optical fiber 9.Preferably, it also comprises retracing spring 4, and retracing spring 4 is arranged between button 2 and base 8, makes button get back to original state when dialling to stretch when structure 5 is pushed aside by the elastic force of retracing spring.
Preferably, it also comprises and group stretches structure 5 for what stop when button 2 is pressed that button 2 returns naturally.Dial in the present embodiment and stretch structure and comprise spring and the ball valve with spring contact, ball valve contacts with button lip, and the radius of ball valve is greater than the moving displacement of button.Under normality, ball valve contacts with button lower limb, and spring is in nature or confined state; When button 2 is pressed, ball valve is to spring movement under the pressure of button 2, and when button 2 continues to press, ball valve gets back to the top of button 2 by the elastic force of spring, contacts with the coboundary of button 2, thus stops the natural return of button 2.When threat is removed, professional utilizes professional tool that ball valve is allocated to spring, can make button 2 return.Should be understood to, other can complete this function dial stretch structure also belong to the utility model protection scope, such as flexible " Y " shape prong like etc.
In the present embodiment, button 2 is organic glass material button, and elastic body 7 is polyurethane elastomer.
When outside breaking out of fire, after patrol officer confirms breaking out of fire, the button 2 manually pushed for emergency on device, dial stretch structure 5 button 2 is locked in below, button 2 drives the push rod 3 of below to move downward, make elastic body 7 that deformation occur, the deformation of elastic body 7 causes heeling-in fiber grating 6 within it to stretch, the reflection wavelength of this fiber grating 6 is made to become large, fiber Bragg grating signal processor, by measuring the variable quantity of the bragg reflection wavelength of elastic body 7 internal optical fiber grating 6, judges external alarm signal.
After the condition of a fire is eliminated, pushed aside by specific purpose tool and stretch structure 5 pairs of buttons 2 and reset, stretch after structure pushed aside when dialling, button 2 moves upward and leaves elastic body 7 under the effect of retracing spring 4, elastic body 7 recovers state of nature under the effect of its own resilient, and then makes heeling-in fiber grating 6 wherein produce contraction, and the reflection wavelength of fiber grating is diminished, after fiber Bragg grating signal processor process, produce the releasing alerting signal of control signal real-time online.
This device is prepared from based on fiber grating, there is the advantages such as electromagnetism interference, multiplexing capacity are strong, long transmission distance, intrinsic safety, the job requirement for environmental sealing type, explosion-proof type and essential safe type can be met, go for the place that oil, tunnel, natural gas line, chemical industry, metallurgical electric power, the fire-fighting energy, storage etc. are strict to electricity requirement and darkness is moist and use.
