Abstract
The utility model relates to a but infrared test range's of accurate control device, infrared detector arranges in intraductally, the front end of pipe has an opening, there is a spiral rear end of pipe, precession through the screw rod with screw out, can adjust infrared detector apart from orificial distance, change test range. These article are arranged in the public place, environment that the flow of personnel is big, realize local important device accurate survey to report to the police have better effect, it influences not flowed by personnel, only has a mind to closely during by protection device as the people, just can report to the police the good reliability.
Description
Technical field
The utility model belongs to a kind of infrared receiver alarm.
Background technology
Infrared eye is made up of Fresnel Lenses, thermoelectric element, current-to-voltage converter, warning circuit, the infrared ray of human body or animal release, through Fresnel Lenses, focus on thermoelectric element, thermal information is converted to current information, then is converted to information of voltage output, triggering work circuit alarm, the scope of detection is determined by the scope of Fresnel Lenses optically focused, and general range is all very large.
Summary of the invention
Technical matters to be solved: the scope how limiting the human body infrared body line entering Fresnel Lenses, realizes the effect of accurate adjustment investigative range.
The technical scheme of dealing with problems:
Infrared eye is placed in pipe, and there is opening the front end of pipe, and there is spiral the rear end of pipe, by precession and the back-out of screw rod, can adjust the distance of infrared eye apart from the mouth of pipe, change investigative range.
Beneficial effect: this product is used in public place, the environment that flow of personnel is large, the accurately detecting warning realizing local important device has better effects, and not by surrounding people's flow effect, only have when people has a mind to close to protected device, just can report to the police, reliability is strong.
Accompanying drawing explanation
Fig. 1 accurately can control the device of infrared acquisition scope
In Fig. 1: 1 infrared eye 2 pipe 3 spiral 4 spring
The device of infrared acquisition scope accurately can be controlled after Fig. 2 changes investigative range
Embodiment
By metal tube, front opening, rear end is added a cover closed, and closure center opens aperture, get the screw rod that mates with aperture from aperture precession, bonnet is connected with effective spiral, is loaded in pipe by spring, then is put into by infrared eye, lid screws on, screw rod screws in, and adjustment screw rod screw-in length, changes the distance of detector apart from the mouth of pipe.
Claims (1)
1. accurately can control a device for infrared acquisition scope, it is characterized in that: infrared eye is placed in pipe, there is opening the front end of pipe, there is spiral the rear end of pipe, by precession and the back-out of screw rod, the distance of infrared eye apart from the mouth of pipe can be adjusted, change investigative range.
