Embodiment Construction

[0015] Specific examples are now used to illustrate the technical solution. Figure 1-3 Shows the structure and relationship of the components of the ventilation and radiation protection device for the weather shutter of this example, including the shutter 6, temperature sensor 8, and humidity sensor 7. The ventilation and radiation protection device includes a radiation protection cover and an exhaust component. The aforementioned radiation shield is composed of a shield body 3, a shield top 1 and a fairing net 2. The shield body is a hollow cylindrical body, and the lower half of the shield body has two rows of small circular holes 11 with an included angle of 90 degrees. A honeycomb rectifier net 2 is installed in the cylinder near the top of the cover. The temperature and humidity sensors (7, 8) are installed under the rectifier net. The cover top is fixed on the top of the cover. There is a gap between the two. The air assembly includes an exhaust fan 4 and a controller 5,...

Abstract

The invention provides a ventilation and anti-radiation device for a meteorological instrument shelter and belongs to the technical field of meteorological detection. An observation environment which is not influenced by the radiation condition inside the instrument shelter is created in the instrument shelter. The device comprises an anti-radiation cover and an air exhaust assembly. The anti-radiation cover is composed of a cover body, a cover top and a gauze screen. The gauze screen is arranged in a cylinder close to the top of the cover body. The cover top is fixed at the top of the cover body, and a gap is formed between the cover top and the cover body. A temperature and humidity sensor is arranged below the gauze screen. The air exhaust assembly comprises an exhaust fan and a controller. The exhaust fan is fixed below the temperature and humidity sensor. The controller is connected with the exhaust fan. According to the technical scheme of the invention, the influence of the radiant heat on element detection data in the instrument shelter is reduced. Meanwhile, the data accuracy and the data usability are improved.

Description

Technical field [0001] The ventilation and radiation protection device for meteorological shutters provided by the present invention belongs to the technical field of meteorological detection. Specifically, it relates to reducing the influence of solar radiation on humidity sensors and temperature sensors in the shutters and improving the accuracy of detection data. Background technique [0002] At present, the observation of temperature and humidity in the meteorological industry is generally placed directly in a louver box. The louver is a protective device for installing temperature and humidity instruments. Its function is to prevent the direct radiation of the sun and the radiation emitted by the ground to the instrument, protect the instrument from strong wind, rain, snow, etc., and make the instrument sense part With proper ventilation, it can truly sense changes in outside air temperature and humidity. The louver box is usually made of wood or glass fiber reinforced plas...
