Description

Butterfly type sand storm concentration level flux real-time dynamic acquisition monitoring device Technical Field The utility model relates to the field of sand and dust collection monitoring equipment, in particular to a butterfly type sand and dust storm concentration level flux real-time dynamic collection monitoring device. Background Sand storms are large scale processes of migration of fine particulate matter produced by surface wind erosion under strong airflow. The sand storm process includes the release of erodible surface sand into the atmosphere, the migration of sand in the gas stream, and the settling of sand. The formation of chinese loess plateau and the distribution of the world's continental loess accumulation areas have demonstrated that sand storm is a bio-geochemical cycling process on earth for millions of years. However, with the blind reclamation and utilization of the land by human beings, large-area land desertification is caused, so that the sand storm activity is enhanced, disasters are frequent, the deserts, gobi and desertified lands are widely distributed in northwest inland arid regions of China, the land surfaces are dry and loose, vegetation protection is lacked, favorable conditions are provided for the occurrence of the sand storm objectively, and the history is the main sand dust source region of China. In order to study the sand storm control method, the sand dust level flux is a very important physical quantity, so that the relation among wind speed, wind direction and sand storm is required to be studied from scientific experimental activities, and for this purpose, a multi-point and omnibearing instrument for collecting sand dust flux data is required to be arranged on the sand storm site so as to observe the wind, the sand storm and the sand conveying quantity, thereby facilitating the study and engineering calculation of the sand storm sand flow. The utility model patent named as a wind power rotary centrifugal sand collector is disclosed in CN209656365U, and comprises a conical barrel and a cylindrical barrel which are combined, wherein the conical barrel is in a conical funnel shape. The cylindrical barrel is provided with a sand inlet, the sand inlet is cut in along the edge of the cylindrical inner barrel, a wind vane and a direction indicator are arranged on two sides of the middle part of the cylindrical barrel, a hollow circular tube at the top of the cylindrical barrel is fixedly connected with a centrifugal propeller, the hollow circular tube penetrates through the cylindrical barrel and is connected with a wind cup rotating bearing, an exhaust hole is formed in the top of the hollow circular tube, a sand and dust dropping nozzle is arranged at the bottom of the conical barrel, the conical barrel is located on a rotating body support with the wind vane rotating bearing, the rotating body support is connected with a fixed support flange plate on a gradient tower, a protection box is arranged below the rotating body support, and a sand collecting cup is arranged in the box and is opposite to the sand and dust dropping nozzle. In the above patent, although it can be determined that the sand flow in the storm can collect the horizontal flux of sand suspension of sand in a unit area in a high layer in unit time, when the sand conveying rate is determined and calculated, the sand collecting cup needs to be taken out of the protection box to weigh the collected sand sample, the method cannot monitor and automatically read data in real time, and can not realize the collection of dust-containing particle concentration amount in unit area in different heights and different directions in a specific environment of the storm for a long time, and the sand in the sand collecting cup can have residues in the process of falling from the sand inlet to the sand collecting cup through the conical funnel, so that the sand weight in the sand collecting cup can generate larger deviation, thereby further affecting the determination and calculation of the sand conveying rate. In order to solve the problems, the utility model provides a butterfly type sand storm concentration level flux real-time dynamic acquisition and monitoring device. Disclosure of Invention Aiming at the situation, in order to overcome the defects of the prior art, the invention provides a butterfly type sand storm concentration level flux real-time dynamic collection monitoring device, which is used for solving the problems that in the background art, when the sand conveying rate is measured and calculated, a sand collection cup needs to be taken out of a protection box to weigh a collected sand sample, automatic data reading cannot be monitored in real time, collection of dust-containing particle concentration amounts in unit areas in different heights and different azimuth unit time cannot be achieved in an unattended or sand storm specific environment, and sand wind remains in the process of falling from a
