Abstract
The utility model provides a full-view type flame detection device comprising a shell, a flame detector, an optical fiber guide pipe and an optical fiber, wherein the flame detector is arranged in the shell; the optical fiber guide pipe is located at the rear end of the flame detector; and the optical fiber is arranged inside the optical fiber guide pipe. The full-view type flame detection device further comprises a lens cone and at least one wide-angle lens; the lens cone is mounted at the front end of the inner cavity of the flame detector; and at least one wide-angle lens is arranged in the lens cone. A flame image is projected to the optical fiber through a plurality of groups of lenses in the lens cone and an optical signal is transmitted to a sensor of the detector by the optical fiber. The optical fiber transmits a flame signal detected by the wide-angle lens into the flame detector so as to finish the collection of the flame signal. According to the full-view type flame detection device, a flame visual angle of the detector is additionally arranged, thereby overcoming the detection omission phenomenon of the detector, which happens because the visual angle is small or a mounting position is inaccurate. Meanwhile, the optical lens cone is arranged so that the distance between the optical fiber and the flame is lengthened and the possibility that the optical fiber is damaged at a high temperature is reduced.
Description
Technical field
The utility model relates to flame detection technique field, particularly a kind of panorama type flame detecting device.
Background technology
Ordinary lens is when observation flame, because its visual angle is little, the scope of observation flame is narrow and small, often occurs leaking and sees phenomenon, thereby cause shutdown of boiler, causes heavy losses to power plant.
Summary of the invention
The purpose of the utility model is to provide a kind of panorama type flame detecting device; Through wide-angle lens and lens barrel; Increase the visual angle and the definition of probe observation flame, the monitoring flame dead angle problem of seeing flame occurs leaking thereby solve the direct observation of rocket probe flame preferably because of the visual angle is little.
For realizing above-mentioned purpose, the technical solution of the utility model is:
The panorama type flame detecting device, comprise housing, be arranged at flame detecting probe in the housing, be positioned at the flame detecting probe rear end fibre-optic catheter and optical fiber; It is characterized in that, also comprise that lens barrel is installed on the front end of said flame detecting probe inner chamber; At least one wide-angle eyeglass is arranged in the lens barrel.
Further, the setting of described lens barrel Inner Front End comprises the lens set of a wide-angle eyeglass, and this lens set also comprises some lenses.
The lenses of the corresponding optical fiber side of described lens set is light-collecting lens or focusing lens.
Described wide-angle eyeglass is quartzy wide-angle eyeglass.
Described wide-angle eyeglass closely contacts with the optical fiber of rear end.
Described flame detecting probe inner chamber front inner wall is established one and is supplied the spacing fixing step of lens barrel.
Described lens barrel inwall is provided with and supplies wide-angle eyeglass and lens set lenses to be embedded fixing fixed groove.
The advantage of the utility model is:
The utility model adopts wide-angle lens and lens barrel connected mode; Wide-angle lens is positioned at the lens barrel front end; Directly stretch into to keep away in the boiler and carry out flame observation, flame image projects in the fibre-optic catheter through the multiple lens in the lens barrel in wide-angle lens is incident to lens barrel; Through optical fiber flare up fire is transferred to the sensor on the probe, accomplishes the collection of flare up fire.Wide-angle lens and lens barrel have enlarged the visual angle of probe observation combustion flame, have solved flame detecting probe and in observation flame process, the problem of seeing occurred leaking.Optical fiber is arranged on the lens barrel end signal is transmitted, and has avoided the unstability of optical fiber heatproof, utilizes outer catheter protection optical fiber in the optical fiber, increases the security stability of optical fiber transmission signal.
