The existing unit is mainly an upwind unit, and the wind wheel is located at the upwind position of the cabin. Existing anemometers are typically mounted on the nacelle cover, i.e. downwind of the rotor. After wind passes through the wind wheel, the energy is partially converted into mechanical energy for the rotation of the wind wheel, and the wind speed and the wind direction at the wind wheel are different due to the existence of blades, so that the control judgment of the unit is influenced, and the generated energy is influenced.
The conventional anemometer is generally horizontally arranged, only the change of wind direction on a horizontal plane can be measured, the change of wind direction on a vertical plane exists in the complex terrain of an actual unit, whether the wind power in the vertical direction is required to be measured or not is required to be measured, and underestimation of wind load is avoided.

Detailed Description
The invention will be further described with reference to specific examples and figures.
As shown in the figure, the wind turbine guide cover comprises a guide cover 1 which is arranged outside a hub of the wind turbine. The air guide sleeve 1 is internally provided with a controller 4, a dynamic pressure manometer 5, a static pressure manometer 6, a wind wheel azimuth angle instrument 7 and a thermometer 8, wherein the controller 4 is connected with a power supply and outputs signals, and the dynamic pressure manometer 5, the static pressure manometer 6, the wind wheel azimuth angle instrument 7 and the thermometer 8 are respectively connected with the controller 4. The controller 4 can adopt a singlechip to directly receive the electric signals output by the sensor. The front end of the air guide sleeve 1 protrudes, a plurality of holes are formed in different positions of the surface of the protruding portion, a anemometer connector 2 is installed in each hole, the anemometer connector 2 is connected with a dynamic pressure manometer 5 through a pipeline 3, and a plurality of anemometer connectors 2, the pipeline 3 and the dynamic pressure manometer 5 form an anemometer array. When a certain wind speed and direction flow blows to the guide cover, the dynamic pressure manometer corresponding to the holes at different positions measures different results, the wind speed of each measuring point can be calculated according to the dynamic pressure and the static pressure of each measuring point, and the wind direction can be solved through the wind speed of each measuring point. In order to improve the accuracy of measurement, a plurality of holes can be formed in the center of the protruding portion of the air guide sleeve 1 and densely distributed along the circumferential direction of the center, and a plurality of holes can be formed in different positions outside the circumferentially arranged holes, wherein the obtained wind direction is a vector of a three-dimensional space, namely, the wind direction not only comprises the direction on the horizontal plane but also comprises the wind direction on the vertical plane. The hydrostatic manometer 6 may be installed in the hub according to the internal space structure, and the combination of the dynamic pressure manometer 5 and the hydrostatic manometer 6 also has a function of measuring the atmospheric pressure.
A hygrometer 9 can be further arranged in the air guide sleeve 1 and used for acquiring humidity parameters, and the hygrometer 9 is also connected with the controller 4 to realize unified power supply and data output. The wind turbine azimuth meter 7 may be mounted in the hub with the measurement center axially coincident with the wind turbine rotation. The wind wheel azimuth angle meter 7 obtains the real-time azimuth angle of the wind wheel by using an inclination angle sensor, an encoder or a proximity switch, and obtains the rotation speed of the wind wheel by calculating the azimuth angle which changes along with time. Because the wind wheel rotates, the measured wind speed and direction are relative wind wheels, the wind wheel azimuth angle and the rotating speed are measured through the wind wheel azimuth angle meter, and the wind speed and direction of the relative cabin are obtained.
According to the invention, the air density is calculated through the measured values of the thermometer and the static pressure manometer; according to the measured dynamic and static pressure difference and the air density, calculating the wind speed at the measuring point; according to the wind speed at the measuring point, the positions of the measuring points and the shape of the guide cover, the wind direction of the relative wind wheel is calculated; and obtaining a wind wheel azimuth angle and a wind wheel rotating speed according to the wind wheel azimuth angle instrument, converting the wind speed and the wind direction of the relative wind wheel into the wind speed and the wind direction in the three-dimensional direction of the relative cabin, and detecting comprehensively and accurately.
