Abstract
The utility model relates to a blast furnace wind-gap pick-up device. The shell at the rear part of an installation flange is provided with an observing tube that is communicated with the shell and an observing port of the observing tube; a semi-transparent semi-reflection plane mirror is arranged in the light path of the shell corresponding to the observing tube; the observing tube is provided with a plane mirror corresponding to the semi-transparent semi-reflection plane mirror; the semi-transparent semi-reflection plane mirror, the plane mirror and the observing port form a reflection light path of the injection optical line on the front end of the shell. A wavelength calibration spectral filter that can filter the bright light is arranged on the rear part of a lens combination. According to the reflection principle of the plane mirror, sight inside the blast furnace wind gap can be directly seen through the observing port, thereby providing convenient condition for the operator in front of the blast furnace to observe the running situation of the blast furnace. The imaging camera shot of the device is provided with a filter that is used for filtering the bright light, which can effectively prevent the problem that the resolution of the image at the display terminal is poor during the glaring, thereby improving the displayed apparent resolution of the image. The device has the functions of image display and direct observation, and has the remarkable advantages such as novel structure, high bright image resolution and convenient application.
Description
Technical field
The utility model belongs to camera head, particularly relates to a kind of blast furnace tuyere pick-up device.
Background technology
In the prior art, be applied to its primary structure of image pick-up device of blast-furnace tuyere by the mounting flange dish of cylindrical case, cylindrical case front end, in the cylindrical case common imaging lens, optical image is converted to the camera of visual electrical signal and visual electrical signal output cable is formed.
There is following defective in the above-mentioned image pick-up device that is applied to blast-furnace tuyere: the vision signal of camera output only is transferred to the display terminal of blast furnace operating chamber, the blast furnace operating personnel of patrolling and examining can not directly observe operation conditions such as blast-furnace tuyere coal powder injection at the scene by this camera head, are unfavorable for the operation of blast furnace situation is in time implemented control or processing.In addition, the common imaging lens of above-mentioned image pick-up device configuration can not adapt to the environment for use of brightness wide variation in the stove, and the complete white image of image resolution-ratio extreme difference even appearance was crossed bright image and made operator can't observe situation in the stove when particularly brightness was higher.
Summary of the invention
The utility model is to propose a kind of blast furnace tuyere pick-up device in order to solve the above-mentioned technical problem that has the image pick-up device existence that is applied to blast-furnace tuyere now.
The utility model is taked following technical scheme for realizing its purpose: this camera head is by cylindrical case, the mounting flange dish of cylindrical case front end, imaging lens in the cylindrical case, the camera and the visual electrical signal output cable that optical image are converted to visual electrical signal are formed, it is characterized in that: the cylindrical case at mounting flange dish rear portion is provided with the inspection section that communicates with it, inspection section is provided with the porthole that has the angle of cut with its axis, be provided with semi-transparent semi-reflecting plane mirror in the cylindrical case light path of inspection section correspondence, the bending connection section of inspection section and porthole is provided with and the corresponding plane mirror of semi-transparent semi-reflecting plane mirror, semi-transparent semi-reflecting plane mirror, plane mirror and porthole form the reflected light path that the cylindrical case front end is injected light.
The utility model can also be taked following technical measures:
The porthole of described inspection section is provided with green color filter.
Described imaging lens is provided with in the light path at its compound lens rear portion by packing ring two-stage Wavelength calibration spectral filter at interval, the filtering high light.
The beneficial effects of the utility model and advantage are: this camera head is provided with inspection section, according to the flat mirror reflects principle, can directly see scene the blast-furnace tuyere from its porthole, observe operation conditions such as blast-furnace tuyere coal powder injection for the flushing and casting personnel at any time the condition that makes things convenient for is provided.The imaging lens of this camera head is set up the two-stage spectral filter of filtering high light, the disadvantage of display terminal image resolution-ratio variation in the time of can avoiding high light effectively, thus improved the sharpness of pictorial display.The utility model has two kinds of functions of pictorial display and direct viewing concurrently, has novel structure, high-brghtness picture images resolution and obviously improves and outstanding advantage easy to use.

Embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing thereof.
Embodiment as shown in the figure, the cylindrical case 1 at mounting flange dish 7 rear portions is provided with the inspection section 2 that communicates with it, and inspection section 2 is provided with the porthole 3 that has the 30-45 ° of angle of cut with its axis, and porthole is installed with green color filter 4.
Be provided with the semi-transparent semi-reflecting plane mirror 6 that is 45 ° of angles of cut with the cylindrical case axis in the light path of the cylindrical case 1 of inspection section 2 bottom correspondences, inspection section 2 is provided with and the corresponding plane mirror 5 of semi-transparent semi-reflecting plane mirror with the bending connection section of porthole 3, and semi-transparent semi-reflecting plane mirror 6, plane mirror 5 and porthole 3 form the reflected light path that the cylindrical case front end is injected light.The rear portion of semi-transparent semi-reflecting plane mirror 6 is compound lens 8 of imaging lens.
As shown in the figure, be provided with in the light path at compound lens 8 rear portions by packing ring 9 the two poles of the earth Wavelength calibration spectral filter 10 at interval, the restriction high light, first step spectral filter is selected model HOB445 for use, and second stage spectral filter is selected model ZAB10 for use.The two poles of the earth Wavelength calibration spectral filter can the filtering stove in high light, the image definition of display terminal is obviously improved.
