Whistle analysis type wind power monitor

Abstract

The invention provides a whistle analysis type wind power monitor. The whistle analysis type wind power monitor comprises a base, wherein a fixed cuboid column is arranged on the top of the base in an extension mode, an air inlet hole is formed in each of the four side faces of the cuboid column, the air inlet holes are formed in the positions with the equal horizontal heights, the portion, arranged inside the cuboid column, of each air inlet hole is connected with a flow guiding pipe, each flow guiding pipe is connected with a whistle, a sound pick-up is assembled on each whistle in a matched mode, the sound pickups are electrically connected with a common arithmetic unit, the arithmetic unit calculates the wind direction and the wind speed according to audio signals picked up by the sound pickups, and the monitoring result is sent to a display and is displayed by the display. The whistle analysis type wind power monitor can resist severe weather environments, and cannot be easily damaged, and high measurement accuracy can be kept for a long time.

Description

technical field [0001] The invention relates to the field of meteorological monitoring equipment, in particular to a wind monitor. Background technique [0002] In the current meteorological monitoring work, wind monitoring is the most basic monitoring task. For wind monitoring, windmill monitors are generally used at present, which include a windmill body, which passes through a vertical The rotating shaft is fixed on the base, and behind the windmill body is a roughly vertical plane tail, so that when the wind blows from any direction, the windmill body will be deflected to the direction facing the wind direction due to the effect of the tail, and then, The windmill impeller parallel to the cross section of the windmill body, that is, perpendicular to the empennage, bears the wind force from the front; the wind speed and direction can be determined by the rotation speed of the impeller, that is, the angle through which the rotating shaft of the windmill body turns.

AI Technical Summary

Problems solved by technology

[0003] For this kind of windmill monitor, its disadvantage is that it uses more moving parts to monitor the wind force. On the one hand, since the monitor is placed in the open air, the lubrication performance of the moving parts cannot be guaranteed for a long time, especially The rotation of the windmill impeller and the change of its lubricity will directly affect the measurement of wind speed, so the measurement accuracy is limited; completely scrapped
