Technical Field
The utility model relates to a meteorological instrument technical field specifically is a radiation protection cover with double-deck drainage device.
Background
Radiation such as direct solar radiation, radiation reflected by an underlying surface, scattered radiation, and long-wave radiation affects the measurement of the meteorological temperature sensor, so that the observed value of the meteorological temperature sensor is higher than the air temperature of the surrounding environment, and the resulting error is called radiation error. In order to reduce radiation error, it is necessary to block various kinds of radiation from directly irradiating the temperature sensor as much as possible, while increasing the air flow velocity around the temperature sensor as much as possible. At present, a shutter box or a radiation shield is usually used for blocking various kinds of radiation from directly irradiating the temperature sensor. However, the louvres or radiation shields may not completely block the various radiations and still create a radiant heating that causes the air flowing inside to be heated, causing the internal temperature sensor to observe a higher temperature than the external free air. In addition, the structures of the louver box and the radiation shield are not favorable for air circulation, and the air flow speed around the internal temperature sensor can be reduced, so that the measurement accuracy and the response speed of the internal temperature sensor are further reduced. The radiation error of the temperature sensor based on the louver box and the radiation-proof cover can reach 1 ℃ or even higher. A good radiation shield design should not only block as much radiation as possible from reaching the temperature sensor surface, but also at the same time increase the air flow velocity around the temperature sensor as much as possible. The two design requirements are mutually contradictory, and the improvement of the performance of the radiation shield for meteorology brings difficulties.
