Description
Technical field
The present invention relates to a kind of device of measuring wind wind direction.
Background technology
Anemometer mainly is divided into mechanical type and on-mechanical formula two classes on the market at present.Mechanical type mainly comprises wind-cup type and propeller type, and since in the routine use mechanical friction and sandstone cause its serviceable life not high to the effect that impacts of rotatable parts.Particularly under low temperature freezes situation, in historical rare sleet and snow ice weather in 2008, disaster-stricken province a large amount of mechanical type anemometer weathervane, vane are frozen in and can not rotate, and cause anemometer malfunctioning.The on-mechanical formula mainly comprises hot type (hot line, hot-bulb) and ultrasound wave two classes.Its probe stream field of hot type anemometer has certain disturbance, also have the hot line easy fracture, need the shortcomings such as periodic maintenance and calibration, so it uses also relatively limitation.Although adopt ultrasound wind measuring accuracy higher, price is expensive, and has relatively high expectations in the installation site.And also do not see on the market based on the anemometer of dynamometry mode.
The correlative study that cylinder and ball are surveyed wind speed and direction has the people carrying out, but cylinder and ball can run into the aerodynamics problem when the measuring wind wind direction.Cylinder and ball circumferential motion problem Chinese scholars early have research, at Reynolds number about 3 * 10
5The time, its resistance coefficient has a precipitate zone, is called critical Reynolds district, and it is namely suffered that to make a concerted effort with wind speed be not monotonic relationshi completely, and in critical Reynolds district, the suffered aerodynamic force of wind speed and cylinder and ball is not one to one.And the factor analysis such as the size of critical Reynolds number and incoming flow turbulivity, cylinder ball surfaceness change.When reynolds number Re hour, its boundary layer, windward side is laminar flow, the stalling point position is forward, about 85 ° of windward sides, lee face Disengagement zone area is large, pressure is low.Along with Re improves, reach critical Reynolds number after, the windward side boundary-layer flow is twisted separating forward, is separated into turbulence separation.Turbulent flow is kept the jet attached flow ability strong because the ectonexine energy exchange is strong, thus the burble point position move after to 100 ° of lee faces, lee face pressure gets to a certain extent and to recover, and the Disengagement zone area dwindles greatly, so the resistance coefficient resistance coefficient is die-offed.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide a kind of suitable environment wide, measurement result is the device of reliable measuring wind wind direction more accurately.
Purpose of the present invention is achieved by following technical proposals: comprise and facing the wind beaer, deformed rod, mount pad, sensor, data line and the main frame of special software is installed; Described down with the wind beaer, deformed rod and mount pad from top to bottom der group are fitted together; Described installation of sensors is on deformed rod, and the output terminal of sensor is electrically connected with main frame by data line; The described beaer that facings the wind forms rigid structure by two orthogonal risers, vertically and/or mutually runs through vertical between two riser cubic phases.
The rectangular structure of the xsect at the position of sensor installation on the described deformed rod.
The dress sensor of installing on the described deformed rod is the tensile strain sheet.
The dress sensor of installing on the described deformed rod is the pressure-strain sheet.
The outer contour of described riser is that straight line and/or curve form.
Compared with prior art, the present invention has the following advantages: simple structure is reasonable, has solved the technical barrier of the art, has overcome the technical barrier in critical Reynolds district, so that measuring accuracy is more precisely reliable.
