Description

TECHNICAL FIELD

[0001] The utility model relates to a collection device, concretely relates to a directional wind snow flow collection device belongs to the field of wind blowing snow observation. BACKGROUND

[0002] Wind blowing snow is also called wind snow flow, that is, the atypical two-phase flow of air carrying snow particles, and is also a phenomenon that snow particles are blown up by wind and run with the wind, snow particles run with the wind under the action of wind, natural snow is thus redistributed, and snow phenomenon several times thicker than natural snow is formed in local. Wind blowing snow hazards are widely distributed in China, including Tibet Autonomous Region, Xinjiang Uygur Autonomous Region, Inner Mongolia Autonomous Region and part of mountainous areas in the northeast, and every winter, wind blowing snow causes serious snow accumulation on highways and railways, obvious reduction of visibility and traffic congestion, which easily causes various serious accidents, seriously threatens the safety of people's lives and property, and increases the work difficulty of disaster prevention and relief, greatly affects and restricts the stable development of local social economy, so reasonable measures must be taken for prevention and control, and the height distribution characteristics of wind snow flow need to be understood before the prevention and control method is researched. At present, there is no device for observing wind snow flow in China, and the snow accumulation behind the set snow barrier is generally used to measure the size of wind snow flow, which has the problems of low precision and height distribution. The WS-SPC-95 wind snow flow monitoring system of the United States determines the density of snow particles by the number and size of the points generated by the snow particle impact sensor. Since snow has strong thixotropy, the particles are dispersed after impact, the area is expanded, the density of wind snow flow is further expanded, and the counting is sharply increased, so the authenticity of the data is lost. Therefore, further improvement is needed. CONTENT OF THE UTILITY MODEL

[0003] The utility model aims at overcoming the above technical defects, and provides a directional wind snow flow collection device, which has wide sampling distribution and is convenient and fast to disassemble and assemble.

[0004] In order to achieve the above technical purpose, the utility model adopts the following technical scheme

[0005] A directional wind snow flow collection device, comprising a plurality of layers of stacked snow storage boxes, wherein one side of each snow storage box is provided with a snow inlet box, the snow inlet box is in communication with the corresponding snow storage box, the snow storage box and the snow inlet box are connected through a clamping mechanism, the upper and lower adjacent snow storage boxes are connected through a plug-in mechanism, and one side of each snow inlet box is provided with an air inlet, and the other side is provided with an air outlet.

[0006] Further, the snow storage box comprises ten layers, the width of the snow inlet box increases gradually, and the air inlet position of each snow inlet box is flush in the vertical direction.

[0007] Furthermore, the height and width of the first to third snow storage boxes from bottom to top are 20cm; the height and width of the fourth to sixth layers are 10cm and 30cm; and the height and width of the seventh to tenth layers are 10cm and 20cm.

[0008] Furthermore, the snow inlet box includes a horizontal inlet and a vertical channel; the upper part of the snow storage box has a through hole relative to the vertical channel; the locking mechanism includes a first protrusion disposed on the edge of the through hole.

[0009] Furthermore, the bottom of the vertical channel is provided with a first connecting hole relative to the first protrusion; the first protrusion and the first connecting hole correspond one-to-one; the vertical channel and the horizontal entrance are arranged in an inverted L shape.

[0010] Furthermore, the insertion mechanism includes a second protrusion disposed on the surface of the snow storage box; a second connection hole is provided on the bottom of the upper adjacent snow storage box relative to the second protrusion.

[0011] Furthermore, a ventilated steel mesh is provided at the air vent; a snow-retrieving door is provided on the back of the snow storage box.

[0013] This invention offers the following advantages: it can collect snow and wind flow within a range of 0-1m or higher, and measure the distribution of snow and wind flow along altitude; the collection device is divided into snow inlet boxes and snow storage boxes. Because the lower snow and wind flow is larger, the lower three layers of snow inlet boxes and snow storage boxes are slightly larger, while the upper snow storage box is relatively smaller, and the top four layers have smaller snow and wind flow, so the snow storage boxes are also smaller. Using snow inlet boxes and snow storage boxes of different sizes allows for the acquisition of specific samples of snow and wind flow at different locations, thereby analyzing the distribution characteristics of the snow and wind flow and addressing shortcomings in scientific research. Calculating the snow and wind flow per unit width is crucial for determining the height and number of snow-blocking barriers, which is essential for the implementation of snow-blocking projects.

[0014] After collecting samples, the accumulated snow was removed, weighed, and its volume was measured. The density of the windblown snow flow was calculated, and the density of natural snowfall was then used as a reference. These calculations yielded the actual volume and weight of the windblown snow flow, thus providing the snow transport volume. The distribution of the windblown snow flow along altitude was obtained after converting the snow at each depth. Attached Figure Description
