Description

Technical Field

[0001] The utility model relates to the technical field of environmental monitoring, and more specifically, to a self-weighing wind and sand collector. Background Art

[0002] Dust storms are a common natural disaster phenomenon in spring. The occurrence and development of dust storms are closely related to the soil conditions and weather conditions of the sand source areas. As the temperature gradually rises in spring, the snow covering the surface of the sand source continues to melt, and the soil humidity is low, which is conducive to the release of sand into the atmosphere, which is one of the necessary conditions for the formation of dust storms.

[0003] The occurrence of sandstorms causes a sharp increase in the concentration of particulate matter in the air, which has a serious impact on the environmental air quality and can affect human health.

[0004] The collection and treatment of dust plays an important role in strengthening the monitoring of sandstorms, analyzing the scope and degree of the impact of sandstorms on ambient air quality, analyzing the sources and components of dust, and proposing treatment measures. The current dust collection device generally consists of a sampling port, a sand collection box, etc., which uses the natural diffusion of air or the formation of negative pressure to drive gas and dust into the dust collection device. The weight of dust in ambient air can be measured by selecting a suitable sampler, taking out the filter paper or other sampling medium from the sampler after sampling, and weighing the sampling medium with a precision balance to obtain the weight of the dust.

[0005] The monitoring of sandstorm weather has problems such as remote location, poor environmental conditions, and difficult operation and maintenance. In addition, the occurrence of sandstorm weather is unpredictable. The existing sand and dust collection devices require manual on-site sample collection and weighing, which cannot capture the sandstorm process in time and cannot provide timely and effective monitoring data.
