Embodiment 1

[0045] Such as figure 1 , Figure 6 and Figure 7As shown, this implementation introduces a wind-shadow resistant wind-measuring tower, which includes a tower tube 1 vertically arranged on the ground, and at least one height on the tower tube 1 is provided with a wind-measuring platform 3 arranged horizontally. At least one set of anemometer 2 is installed on the wind platform 3, and the wind measuring platform 3 is connected to the tower 1 through a rotatable hinge, and the wind measuring platform 3 is also fixedly installed with a vertically arranged baffle in the radial direction. The horizontal extension axis of the windshield 13 and the windshield 13 are set perpendicular to the connecting line between the anemometer 2 and the axis of the tower 1, so that the windshield 13 drives the wind measuring platform 3 to rotate around the tower body under the wind force to The wind instrument 2 is in a direction perpendicular to the wind direction relative to the tower tube 1 ....

Embodiment 2

[0058] Such as figure 2 , Figure 8 and Figure 9 As shown, in this embodiment, a wind-shadow-resistant wind-measuring tower is introduced, including a tower tube 1 vertically arranged on the ground, at least one height surface of the tower tube 1 is a wind-measuring plane, and the wind-measuring plane is set on the opposite At least two anemometers 2 arranged symmetrically on the axis of the tower 1, each anemometer 2 includes a support rod 15, the lower end of the support rod 15 is fixedly connected to the tower 1, and the upper end of the support rod 15 is provided with a support rod 15. A tripod that rotates about the axis. The tripod is provided with at least three wind measuring bowls 16 that are symmetrically arranged relative to the axis of the support rod 15.

[0059] By setting at least two anemometers in the same height plane of the tower, the wind force and wind direction in multiple directions around the tower can be detected to increase the diversity of data c...

Embodiment 3

[0069] This embodiment introduces a wind measurement method based on the wind shadow resistance wind measuring tower in the second embodiment above. At least two wind measuring points arranged at the same distance from the wind measuring tower are used to measure wind direction and wind force, and the wind force and wind direction values ​​measured at the two wind measuring points are combined to obtain the actual measured wind force and wind direction .

[0070] By detecting the wind force and wind direction at different positions on the wind measuring height surface, and obtaining the actual measured wind force and wind direction according to the detected value, the actual measured value integrates the measured values ​​of all directions of the tower, making the measurement result more accurate. The influence of tower wind shadow on measurement results is reduced.

[0071] In this embodiment, the specific steps of wind force measurement are as follows,

[0072] Step 11), r...

Abstract

The invention relates to a wind measurement method of an anemometer tower and a wind shadow resistant anemometer tower. The anemometer tower comprises a tower drum vertically arranged on the ground, wherein the tower drum is provided with horizontally arranged installation rods at the wind measuring height positions, the installation rods are installed on the tower drum in a mode of being capableof rotating around the axis of the tower drum, a first end of each installation rod is provided with wind measuring instruments, a second end of the installation rod is provided with a counterweight block, and each installation rod is provided with a vertically arranged wind blocking plates; and the rotation of the installation rod is monitored after an external force is applied to the installation rod, and the wind direction at the wind measuring height surface of the anemometer tower is obtained according to a rotation angle detection value of the installation rod. The rotating process of the installation rod to which an external force is applied along the wind is monitored, so that the installation rod is enabled to form a wind indicator of the anemometer tower, the wind direction in the same direction as the installation rod can be obtained by only detecting the orientation of the installation rod when changing the rotating direction or the final orientation when the installation rod is static, the wind measuring instrument installation plane is enabled to have a function of measuring the wind direction, and a purpose of accurately measuring the wind direction of the anemometertower is achieved.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a wind shadow-resistant wind measuring tower, and also relates to a wind measuring method for the wind measuring tower. Background technique [0002] In recent years, with the global attention to wind energy resources and the rapid development of the wind power industry, governments, enterprises or wind power developers have begun to invest in the construction of wind measuring towers to obtain first-hand wind energy data for future investment in wind farms. The wind measuring tower is erected in the wind farm site, mostly of quilted frame structure and cylindrical structure, which is reinforced by cable-stayed steel strands, and the height is generally 10-150 meters. Anemometers, wind vanes, and wind measuring instruments such as temperature and air pressure are installed at different heights of the tower body. The wind conditions at the site can be observed continuously ar...
