Abstract
The utility model relates to a transmitting-reflecting self light-collecting two-color water level meter, comprising red glass, green glass, a prism, a green reflecting plate, and a casing, which is characterized in that an original lighting source is cancelled, a light harvesting window is additionally arranged on the casing, a cylindrical mirror or flat glass is arranged on the light harvesting window, an optical differentiation scale plate with quantified display and caption display is additionally provided, and a mirror reflector used for enlarging viewing width, view angle, and viewing distance is arranged at the two sides of an observation window.
Description
The utility model is a kind of transflective light-self-collecting two-colour fluviograph that Water Level in Industry Boiler monitors that is used for.
Existing transflective two-colour fluviograph is made up of illuminating lamp, reflector, red glass, green glass, kaleidoscope prism, view window, green reflecting plate and housing.Green reflecting plate forms the pipeline that can be communicated with boiler with the prism bottom surface, it utilizes the transmission and the principle of reflection of optical prism, when pipeline space is anhydrous, the light of illuminating lamp enters prism through reflector and the red glass of being close to prism side, again after the reflection of prism, enter view window from the another side of prism, on view window, show red.When water was arranged, the light of illuminating lamp directly entered pipeline by green glass and the prism of being close to the prism end face, returns prism through green reflecting plate again, and then showed green on observation panel.This kind water level gauge all is provided with lighting source according to convention, owing to be to make brightly continuously, the lighting source life-span is short, and is fragile, to water level gauge can't be shown, in case have a power failure, all the more so.
It is a kind of not with the transflective light-self-collecting two-colour fluviograph of lighting source that the purpose of this utility model is to provide.
The utility model is achieved in that has cancelled original lighting source in the housing, has set up one and can be equipped with cylindrical mirror or flat glass on the light harvesting window for the light harvesting window of red glass and green glass daylighting on housing.Extraneous light is directly entered in the water level gauge housing from the light harvesting window.
Fig. 1, Fig. 2 are the cross-sectional structure cross-sectional schematic of two kinds of light paths of an embodiment of the design.
Below in conjunction with embodiment the design is described in detail.
The light-self-collecting two-colour fluviograph is made up of red glass 1, green glass 2, prism 3, green reflecting plate 4 and housing, it is characterized in that having cancelled original lighting source, setting up one on housing can be for the light harvesting window of red glass 1 and green glass 2 daylightings, and the light harvesting window is provided with cylindrical mirror 5 or flat glass.
In addition, for strengthening the light harvesting effect, the both sides of light harvesting window are provided with reflector 6,7 in the housing, and in addition, it is octahedra that prism 3 also can be full polishing.
Moreover, be provided with optics differentiation scaleplate with red glass 1 relative prism 3 sides, reaching the quantitative demonstration of water level, and the low-water level warning part of scaleplate also can be carved with " alert danger " captions, to play suggesting effect.Described differentiation scaleplate can have a style of one's own with red glass 1, promptly indicates scale and " alert danger " captions on red glass 1.
To also have, to look wide, visual angle, sighting distance in order increasing, the view window side in the housing is provided with mirror reflective plate 8 or mirror reflective plate 9, preferably in the side of view window mirror reflective plate 8,9 is set respectively.
The utility model breaks traditions, and has cancelled original lighting source, makes under the power down mode, still can observe water level, has prolonged the serviceable life of water level gauge greatly, and is convenient and reliable.
Claims (6)
1, a kind of transflective light-self-collecting two-colour fluviograph, form by red glass, green glass, prism, green reflecting plate and housing, it is characterized in that having cancelled original lighting source in the housing, set up a light harvesting window for red glass and green glass daylighting on housing, the light harvesting window is provided with cylindrical mirror or flat glass.
2, transflective light-self-collecting two-colour fluviograph as claimed in claim 1 is characterized in that the both sides of light harvesting window are provided with reflector.
