Five-hole wind speed probe calibrating experiment table

The present invention discloses a five-hole Winds probe calibration bench. The same size on both surfaces of two circular steel tubes fixed perpendicularly to a rectangular steel plate, two round steel and are respectively slidably connected to the fixed end of the two sliding bearing, two identical boom with a base composition of U-shaped steel suspension basket, the upper end of the two booms are fixed in the other end of each sliding bearing means pivotally connected as by two bolts. U-shaped steel plate center basket sink disposed circular hole and fitted through a circular rotary bearing, open T-shaped groove, is mounted on a T-shaped slot hole Winds five circular rotary probe. Winds five-hole probe wind receiving portion in said U-shaped steel basket pivot axis of intersection of the axis of rotation of the circular rotary. The present invention can quickly and accurately adjust the wind speed five-hole probe sideslip angle and pitch angle, wind speed and kept five-hole portion location of the wind receiving probe calibration in the wind farm to ensure a constant wind speed. Winds can greatly increase the five-hole probe calibration accuracy and efficiency.
