Rotatable creeping sand quantity collector capable of measuring different incoming wind directions

Abstract

The invention provides a rotatable creeping sand quantity collector capable of measuring different incoming wind directions. The collector comprises a wind vane, a wind vane vertical rod, a first conical base, a rotating shaft and a base sand collector; the bottom end of the wind vane vertical rod is connected with the top end of the first conical base; the top end of the wind vane vertical rod isconnected with the wind vane; a sand guide cambered surface is provided with sand guide partition plates and a sand inlet; a valid sand collection box and an invalid sand collection box are arrangedin the base sand collector; the first conical base is fastened to the top of the valid sand collection box; the sand inlet is in conductive connection with the valid collection box; the sand guide cambered surface is in conductive connection with the invalid sand collection box; the first conical base is driven by the wind vane to rotate, so that the inlet sand is opposite to an incoming wind direction; and creeping sand in the incoming wind direction is collected by the valid sand collection box; creeping sand in non-incoming wind directions slides down into the invalid sand collection box through the sand guide cambered surface; and since a plurality of azimuth sand collection boxes are adopted, the collection device can accurately measure the creep quantity of sand grains in different incoming wind directions.

Description

technical field [0001] The invention relates to a sand amount collecting tool, in particular to a rotatable creeping sand amount collector for measuring different incoming wind directions. Background technique [0002] Wind is the main driving force for near-surface soil wind erosion and sand transport and deposition. The deposition of sand and the formation and development of aeolian landforms are the result of wind force. Wind-sand movement is the movement of sand by near-surface airflow. From the perspective of fluid mechanics, sand flow is a mixed flow of air flow and the solid particles (sand particles) it carries. The wind blows over the loose sand surface, and under the action of the wind, the sand particles are separated from the surface and enter the air flow, resulting in wind erosion of the sandy land, resulting in wind-sand movement, and forming sand dune landforms with various terrains. There are three main forms of wind and sand movement, creeping, jumping a...
