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

Embodiment Construction

[0012] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0013] exist figure 1 In the shown embodiment, the pressure-sensing wind monitor includes a base 1, a fixed pole 2 extends above the base 1, a cube 3 is fixed on the pole 2, and the four sides of the cube The two sides are perpendicular to the horizontal plane; the four sides of the cube 3 are respectively affixed with strain gauges 4 of the same type, and each of the strain gauges is electrically connected to the arithmetic unit arranged in the base 1, so that The computing unit calculates the wind speed and wind direction according to the sensing data of each strain gauge, and sends the monitoring result to a display.

[0014] like figure 2 As shown, corresponding to the four sides of the cube 3, the first strain gauge 41, the second strain gauge 42, the third strain gauge 43, and the fourth strain gauge 44 are attached respectively. The greater the wind pre...

Abstract

The invention provides a pressure intensity sensing type wind power monitor. The monitor comprises a base, a fixed supporting rod extends above the base, a cuboid is fixed to the supporting rod, and the four side faces of the cuboid are orthogonal to the horizontal plane. Strain gages are pasted on the four side faces of the cuboid respectively and are electrically connected to an arithmetic device arranged inside the base, the arithmetic device figures out the wind speed and direction according to the sensing data of each strain gage, and monitoring results are displayed by a displayer. The pressure intensity sensing type wind power monitor can resist bad weather conditions, not be damaged easily, and keep good measuring precision 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. [000...
