Protect instrument from the impact of high wind, rain, snow etc., and make instrument sensing part have suitable ventilation, can truly sense the external world
Air themperature and the change of humidity.Thermometer screen is generally made up of wooden or fiberglass bi-material, tank wall two row's blade and level
The angle in face is about 45 °, in " " font, bottom is middle one piece of slightly higher three piece flat board to people, and case top is two-layer flat board, and upper strata is slightly
Tilt backwards.Existing Meteorological Field major part uses reinforced plastics screen, its internal high 615mm, wide 470mm, deep 465mm.
As can be seen here, the solar radiation quantity in thermometer screen directly influences and is arranged on BAIYE the temperature inside the box and humidity sensor
The accuracy of data.With the fast development of meteorological cause, to meteorological detection business need more and more higher, the particularly quality of data
Control aspect.From the point of view of current observation benefit, the observation quality of data of temperature and humidity especially temperature still has much room for improvement.This
Invention is analyzed its reason and is mainly：Thermometer screen is affected by material and structure, and it is more to enter sunray in cartonning, solar radiation quantity
Higher, lead to the accuracy of key element detection data to decline.
Content of the invention
This utility model is related to a kind of ventilation shielding of instrument shelter, its objective is effectively to reduce sun spoke
Penetrate the impact to BAIYE the temperature inside the box sensor and humidity sensor, lift the accuracy of two kinds of observation element data and can use
Property.
The technical solution of the utility model is such：Create one in thermometer screen and be not subject to radiation effect in thermometer screen
Observing environment.
A kind of ventilation shielding of instrument shelter, including thermometer screen, temperature and moisture sensors, its feature exists
In also having ventilation shielding, described ventilation shielding includes radiation shield and vacuum elements, described radioprotective
Cover is made up of cover body, cover top and screens, and cover body is hollow garden cylinder, is installed with rectification in the garden cylinder of covering on top
Net, cover top is fixed on the top of cover body, has space between the two, temperature and moisture sensors are arranged on the lower section of screens, take out
Pneumatic module includes exhaust fan and controller, and exhaust fan is fixed on below temperature and moisture sensors, and controller connects exhaust fan.
A kind of ventilation shielding of described instrument shelter is it is characterised in that cover below described exhaust fan
Body garden cylinder is built with guiding cone.
A kind of ventilation shielding of above-described instrument shelter is it is characterised in that described air inlet net is honeybee
Nest shape net.
A kind of ventilation shielding of described instrument shelter is it is characterised in that the lower half of described cover body has
Two 90 degree of rows or the small garden hole of 180 angles.
Cover top in this programme is responsible for importing the air of suction thermometer screen in cover body；Air inlet net primarily serves dredges air
Effect, make air-flow uniform sequential；Cover body provides installing space and the airflow path of temperature and moisture sensors.Work
When, exhaust fan wind flow extracts the radiations heat energy in thermometer screen, and radiations heat energy is through the deflection cone within the cover body of shielding
Body, Cellular Networks, become uniform in order after the dredging of cover top, reach and reduce solar radiation heat affecting sensor measurement in thermometer screen
Purpose, reduces radiations heat energy to the impact detecting thermometer screen factor data, improves accuracy and the availability of data.
