Description
Technical field
The utility model relates to meteorological to survey instrument, specifically a kind of radiation shield for field test meteorological observation instrument.
Background technology
When carrying out the observation of outdoor field test, data display rice field 1.5m At The Height thermic anomaly is higher than Rice Panicle temperature, by analysis and on the spot after verification, find that the radiation shield disc angle of original field test meteorological observation instrument is less than normal, between disc, gap is excessive, and the inclination angle of disc is less, when measuring more than 1m height temperature, sunlight easily produces warming effect by disc gap direct projection thermometric instruments, cause temperature recording geometry error, especially the sunset, moisture recorder warming effect after shining upon is obvious, thus have impact on field temperature accuracy of observation.
Summary of the invention
The utility model discloses a kind of field test meteorological observation instrument radiation shield of improvement, in order to improve the radiation protection ability of field test meteorological to survey instrument further, improves test observation precision.
Described field test meteorological observation instrument radiation shield is connected by multi-disc disc and is formed a hollow, for the cylindrical cavities of device experiment meteorological observation instrument, it is characterized in that: described radiation shield is combined by polylith disc vertical series, its top disk 3 outer rim is a circle annular slope 3-1, its inclination alpha is 67 ° ~ 77 °, at least containing 5 discs 4 under top layer, disc 4 is also provided with a circle interior annular inclined-plane 4-1, its inclination angle of inclined plane β is 67 ° ~ 77 °, and interior annular inclined-plane inner pitch is Φ is 95mm ~ ~ 105mm.In the middle of the card of each disc, 120 °, interval has disc fixed orifice 2 as the connection between disc in the outer part, connects between each disc with iron wire, and card edge has louvre 1 in order to heat radiation every 40 °.
The utility model adopts disc comparatively high spud angle and two-layer symmetric structure, effectively can shield direct solar radiation and the reflected radiation from any direction, compensate for sunrise and the raying of meteorological observation instrument heats, temperature observed result is undergone mutation at sunset shortcoming; Meanwhile, the multiple tiny hole of top disk is convenient to radiation shield ventilation and heat, ensure that the circulation of air, enables moisture recorder respond to outside air temperature change truly.
