Abstract

The invention discloses a sand-wind monitor with an adjustable angle and capable of improving measurement precision. The sand-wind monitor is formed through connecting multiple sand collectors througha support rod; the sand collectors are fixedly connected to the front ends of support arms through bolt bearings; fixing brackets on the rear ends of the support arms are fixed on the support rod ina staggered way; each sand collector comprises a sand collecting cabin, a collar base, an air inlet, an air outlet, a secondary sand-retaining screen, a wind wing, and a wind wing connecting rod, andfurther comprises a top cap, an angle regulator, the bolt bearing, a primary sand retaining screen, and a spoiler; the top cap is arranged at the top of the sand collecting cabin, the angle regulatoris connected with the collar base and arranged at an upper part of the bolt bearing; the primary sand-retaining screen is arranged at a lower part of the top cap, the spoiler is arranged in the air inlet, and the front part of the sand-collecting cabin is designed as the bevel. The actual technical problems of how to improve the measurement precision of the sand collectors and increasing the monitoring applicable range of the instrument are solved, and the sand-wind monitor is convenient to use and strong in practicability.

Description

[0001] 【Technical field】 [0002] The invention relates to a wind-sand monitoring instrument, in particular to a wind-sand monitoring instrument with an adjustable angle and increased cross-section setting density, which can improve measurement accuracy. [0003] 【Background technique】 [0004] The wind and sand monitor in the prior art: the sand collector of the wind and sand monitor adopts the structural form of a horizontal terrace with a narrow air inlet and a wide air outlet. Rotate the sand collector to ensure that the section of the air inlet is always perpendicular to the flow direction of the wind and sand. The wind and sand enter the air inlet with a small cross-sectional area, forming turbulent flow in the sand collection cabin, and the wind speed decreases. The wind energy driving the suspension of the wind and sand is reduced. Under the joint action of the net, the blown sand is deposited in the sand collecting cabin, and the air flow is discharged from the air out...
