Abstract
The utility model relates to a transmission-reflection type wide-angle bicolor fluviograph, comprising red glass, green glass, a prism, a green reflecting plate, an observation mirror, and a casing, which is characterized in that a mirror reflector is arranged at the lateral surface of the observation window in the casing, an original lighting source is cancelled, a light harvesting window used for helping the red glass and the green glass to gather light is additionally arranged on the casing, and a cylindrical mirror or flat glass is arranged on the light harvesting window, which enlarges the viewing width, the viewing angle, and the viewing distance of the fluviograph, and extends the service life of the fluviograph. The water level can also be observed in the state of power failure.
Description
The utility model is a kind of transflective wide-angle two-colour fluviograph that boiler water level monitors that is used for.
Existing transflective two-colour fluviograph is by illuminating lamp, and reflector, red glass, green glass, kaleidoscope prism, view window, green reflecting plate and housing are formed.Green reflecting plate forms the pipeline that can be communicated with boiler with the prism bottom surface, it utilizes the saturating 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 view window.This kind water level gauge visual angle is very little, and the people can only monitor in the front of view window and use inconvenience.
The purpose of this utility model is to provide a kind of multiaspect of wide viewing angle to show two-colour fluviograph.
The utility model is achieved in that mirror reflective plate has been set up in the side of view window in housing.
Accompanying drawing is the structure cut-away view of the design embodiment.
The wide-angle two-colour fluviograph comprises red glass 1, green glass 2, prism 3, green reflecting plate 4, sight glass 5 and housing, look wide, visual angle, sighting distance in order to increase, mirror reflective plate 6 or mirror reflective plate 7 have been set up in the side of view window in housing, preferably set up a mirror reflective plate 6,7 respectively in the both sides of view window.
In addition, the design has also cancelled original lighting source, and having set 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 8 or flat glass.
Moreover in order to strengthen the light harvesting effect, the both sides of light harvesting window are provided with reflector 9,10 in the housing, and prism 3 is that full polishing is octahedra.
The utility model has been owing to set up mirror reflective plate and increased the light harvesting window, increased that looking of water level gauge is wide, visual angle, sighting distance, and the visual angle is brought up to 90 ° at least, has enlarged 9 times, makes to be the multiaspect developing on the sight glass.Also cancel simultaneously original lighting source in the water level gauge, made under the power down mode, still can observe water level, prolonged the serviceable life of water level gauge greatly.
