Abstract
The utility model discloses a kind of windowpane of transmission-type atmosphere visibility meter, this windowpane is positioned at the front of the optical lens of transmitter and receiver, the glass sheet of described windowpane is coated with electric heating film and hydrophobic film/hydrophilic film.Windowpane is provided with electric heating film and hydrophobic film/hydrophilic film, prevents moisture content in surrounding air in glazing surface frosting, condensation, cover glass window remains dry, improves the measuring accuracy of atmosphere visibility meter, can adapt to long-term outwork.
Description
Technical field
The utility model relates to the measurement mechanism of meteorological optical range in meteorological field, particularly a kind of windowpane of transmission-type atmosphere visibility meter.
Background technology
Meteorological optical range measurement mechanism is mainly used in the greatest optical sighting distance of the fields such as runway, shipping, Hainan Airlines at that time under meteorological condition, is one of important parameter of meteorologic parameter in these fields.Meteorological optical range is measured and is usually adopted following several method:
1. visual observation (subjective observation): refer to artificial observation, visual observation result can differ greatly because of observation condition Different Results, such as observation station height, the eyesight of observation scope and observer and training and psychological condition etc.
2. device is surveyed: measure meteorological optical range by physical testing instrument quantitativeization, main method comprises Forward scattering and transmission beam method.Forward scattering mensuration obtains data by the astigmatism strength near measuring receiver, and these data only represent the measurement result near measurement point, and therefore the uncertainty of measured value is higher.Transmission-type atmosphere visibility meter generally includes a transmitter and a receiver, obtains visibility data by the decay of measuring luminous flux, and major advantage is that point-to-point is measured, and therefore measuring accuracy is apparently higher than scattering method of testing.
Be which kind of transmission-type atmosphere visibility meter all needs to arrange optical lens in transmitter and receiver, outside optical lens, have windowpane to protect.Because visiometer works usually under the open-air atmosphere of the various temperature and humidities of outdoor, the moisture content in air can condense on windowpane, frosting, causes the improper decay of measuring light, affects measuring accuracy.
Utility model content
For problems of the prior art, the purpose of this utility model is the windowpane providing a kind of transmission-type atmosphere visibility meter, prevents that the moisture content in air from condensing on windowpane, frosting, improves the measuring accuracy of visiometer.
For achieving the above object, the technical solution of the utility model is as follows:
A windowpane for transmission-type atmosphere visibility meter, this windowpane is positioned at the front of the optical lens of transmitter and receiver, the glass sheet of described windowpane is coated with electric heating film and hydrophobic film/hydrophilic film.
Further, described windowpane is arranged single-glass sheet, described electric heating film is plated on the inside surface of this single-glass sheet, and described hydrophobic film/hydrophilic film is plated on described single-glass sheet outside surface.
Further, described windowpane is double-deck double glazing, and described electric heating film is plated on the inside surface of inner glass sheet, and described hydrophobic film/hydrophilic film is plated on the outside surface of outside glass sheet.
Further, described windowpane passes through gland clinching on its installation frame, annular pressing ring is provided with between windowpane and described installation frame, described trim ring is embedded with " O " RunddichtringO towards the side of windowpane, installation frame is being embedded with another " O " RunddichtringO towards the side of trim ring, two " O " RunddichtringO extruding trim rings make hermetic seal between windowpane and its installation frame.
The advantage of the windowpane of transmission-type atmosphere visibility meter of the present utility model is: on windowpane, be provided with electric heating film and hydrophobic film/hydrophilic film, hydrophobic film prevents the globule from resting on windowpane, the globule can converge by hydrophilic film, contribute to the globule from windowpane landing, hydrophobic film and hydrophilic film can both prevent moisture content in surrounding air in glazing surface frosting, condensation, electric heating film works incessantly and keeps windowpane to remain dry, improve the measuring accuracy of atmosphere visibility meter, long-term outwork can be adapted to.
