Embodiment 1

[0037] Such as figure 1 , Figure 6 and Figure 7 As 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

[0050] 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.

[0051] 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

[0061] 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 .

[0062] 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.

[0063] In this embodiment, the specific steps of wind force measurement are as follows,

[0064] Step 11), r...

Abstract

The invention relates to power supply equipment of a wind-shadow-proof anemometer tower. The anemometer tower includes a tower tube vertically arranged on the ground, and anemometers are arranged at each wind measuring height of the tower tube respectively; at least one solar panel is arranged at each wind measuring height respectively, the power output end of each solar panel is connected with the power input end of the corresponding anemometer. By the arrangement of the solar panels on the anemometer tower, the anemometer tower can use green solar energy sources to provide dynamical power to the anemometers, therefore, a stable input power source is provided for the anemometers and the anemometers can work steadily; at the same time, by the arrangement of a switchable solar power supply circuit and a thermal power supply circuit on the anemometer tower, the anemometers can use any one power source to work based on the working condition.

Description

technical field [0001] The present invention relates to the field of wind power generation, in particular to a wind-shadow-resistant wind-measuring tower, and also to a wind-measuring method for the wind-shadow-resistant wind-measuring tower, and in particular to a power supply device for the wind-shadow-resistant 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 a...
