Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wind-sand flow detection, in particular to a wind-sand flow automatic detection device. BACKGROUND

[0002] In the desert, wind-sand is everywhere, and wind is the direct power of sand movement. When the wind speed acting force is greater than the inertia force of sand particles, the sand particles are started, forming a wind-sand flow. When the wind-sand flow migrates closely to the ground, the impact and friction of sand particles on the ground material are large. Because the sand particles in the wind-sand flow are concentrated within 30 cm from the ground, the lower part of the electric pole in the desert area can be broken due to abrasion, so it is necessary to monitor the wind-sand. The size of the wind-sand can be judged by the mass of the sand particles in the sand collecting hopper per unit time.

[0003] However, the height of the sand collecting box of the existing wind-sand detection device is usually fixed after being fixed on the ground. It is not convenient for the operator to adjust according to the wind direction, which is not conducive to improving the efficiency of sand collection. When the sand in the sand collecting box needs to be taken, the sand collecting box is usually installed on the fixed frame by bolts, and the operator is not convenient to disassemble the sand collecting box when sampling, which is not conducive to improving the sampling efficiency of the sand. In addition, when the sand collecting instrument is transported, the swing plate is long, and it is not convenient to store during transportation, which is not conducive to improving the use effect of the device.
