Atmospheric observation device capable of preventing dust from entering and changing windward angle through self-suction

Abstract

The invention discloses an atmosphere observation device capable of preventing dust from entering and changing the windward angle through self-suction. The atmosphere observation device comprises a shell and a supporting frame; the shell is a main outer frame structure of the device, an air analyzer and a control box are arranged in the shell, and the control box is located at the right end of the air analyzer; and the supporting frame is located at the top end of the shell, a wind speed detector is arranged at the upper left end of the supporting frame, a wind direction detector is arranged on the opposite face of the wind speed detector, one end of the wind direction detector is fixed to the upper end of the shell, and a movable disc is arranged at the top end of the supporting frame. According to the atmosphere observation device capable of preventing dust from entering and changing the windward angle through self-suction, an arranged sliding frame can move on the inner surface of an air guide plate, and the air guide plate can be cleaned through cleaning rollers on the outer surface, so that the effect of cleaning the inside and the outside can be achieved, the air collection efficiency is improved, and the influence of dust on equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of atmospheric environment observation, in particular to an atmospheric observation device that prevents dust from entering and can change the windward angle by self-absorption. Background technique [0002] With the continuous development of my country's economic level, the problem of environmental pollution has increasingly become a prominent issue related to the sustainable development of the economy and the health of the people. How to accurately analyze the pollutant gases in the atmosphere qualitatively and quantitatively, and take timely control measures is particularly necessary. Passive multi-axis The DOAS observation system uses the sun as the light source and uses the differential absorption method to conduct qualitative and quantitative analysis of regional air pollutants. It is characterized by the ability to detect regional pollutants in a large area in real time, and has been widely used in urba...

Problems solved by technology

[0007] The purpose of the present invention is to provide an atmospheric observation device that prevents dust from entering and can change the windward angle by self-absorption, so as to solve the problem that the windward side is fixed in the device in the above background technology, and it is inconvenient to change the windward side according to the wind direction, thereby collecting air content The concentration of the air is affected, resulting in a decrease in air collection efficiency and affecting the accuracy of observation. The dust-proof structure will accumulate a large amount of dust after long-term use, and the accumulated dust and foreign matter will directly affect the air detection results. At the same time, in rainy and snowy weather, rain and snow It will go deep into the observation device, which will affect the normal operation of the equipment. When the natural wind is small, the amount of air collected is limited and cannot meet the air flow required for normal observation, so that the atmosphere cannot be accurately observed. Therefore, a A problem of preventing dust from entering the atmospheric observation device capable of changing the windward angle by self-absorption
