Problems solved by technology

[0004] Existing wind and dust monitoring devices such as lidar are mostly single-layer measurements, and can only monitor the wind and dust concentration at a certain height or area in the horizontal direction, and cannot collect and monitor wind and dust samples at different heights during a wind and sand weather process
Moreover, the existing wind and dust monitoring devices have relatively simple monitoring conditions, and cannot simultaneously monitor elements such as the collection and measurement of wind and dust content and the velocity of wind and dust flow

Embodiment

[0033] Please refer to Figure 1 to Figure 4 , which shows a sample collection and monitoring system for near-surface wind and dust flow according to the embodiment of the present invention, and the specific structure is as follows.

[0034] Such as figure 1 As shown, an embodiment of the present invention provides a near-surface wind and dust flow sample collection and monitoring system. The monitoring system includes a support rod 1, which is vertically installed in the field where measurement is required, and the lower end of the support rod 1 is inserted into the soil to be fixed and not topple. The support rod 1 is evenly provided with a plurality of wind speed monitoring structures 2 and a plurality of wind and dust flow collection structures 3, the wind speed monitoring structure 2 can measure the wind speed conditions of multiple height layers in wind and sand weather, and the wind and dust flow collection structure 3 can collect wind and dust flow in wind and sand we...

Abstract

The invention provides a near-surface wind and dust flow sample collection and monitoring system, and relates to the technical field of environment monitoring devices, and the system comprises a support rod, the support rod is uniformly provided with a plurality of wind speed monitoring structures and a plurality of wind and dust flow collection structures, and the support rod is also provided with a wind indicator and a fixing structure. The near-surface wind and dust flow sample collection and monitoring system has the advantages of being simple in structure, diverse in function and capable of monitoring wind and dust flow conditions of different heights.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring devices, in particular to a near-surface wind and dust flow sample collection and monitoring system. Background technique [0002] Dust refers to solid particles suspended in the air. Wind and dust are often used as one of the important indicators of field wind and sand weather measurement components. [0003] During a sandstorm in the field, in order to determine various attribute indicators related to the aeolian flow in the near-surface layer, it is usually necessary to monitor the aeolian content and wind speed at different heights in the air. [0004] Existing wind and dust monitoring devices such as lidar are mostly single-layer measurements, which can only monitor the wind and dust concentration at a certain height or area in the horizontal direction, and cannot collect and monitor wind and dust samples at different heights during a wind and sand weather process. Moreover...
