Description

Technical Field

[0001] The utility model belongs to the technical field of wind power generation, and in particular relates to a wind measuring device used for wind power generation. Background Art

[0002] The wind measuring device for wind power generation is a device specially used for measuring wind energy parameters in wind farms. It provides accurate data support for the operation of wind turbines by measuring key parameters such as wind speed and wind direction, so as to ensure the efficient and safe operation of wind power generation systems. However, the existing wind measuring devices for wind power generation have poor stability. When the device encounters strong winds or extreme weather, the strong winds will cause the anemometer and wind vane in the wind measuring device to swing or vibrate greatly, thereby affecting the accuracy of the measurement. The strong wind pressure and wind force generated by the strong wind may exceed the design limit of the wind measuring device, causing damage or destruction to the mechanical structure of the equipment, and reducing the service life of the device.

[0003] Therefore, a wind measuring device for wind power generation is designed to solve the above problems. Utility Model Content

[0004] To solve the problems raised in the above background technology. The utility model provides a wind measuring device for wind power generation.

The semicircular airfoil of the wind plate can generate more efficient lift under the action of wind force, thereby improving the ability of the wind turbine to capture wind energy. This design helps to reduce air resistance, making the wind plate smoother when rotating, thereby increasing energy conversion efficiency and improving the monitoring accuracy of the second measuring device. Under high-speed wind or turbulent conditions, the semicircular airfoil of the wind plate and the design of the first and second ventilation slots opened on the wind plate make the wind plate have better stability. This airfoil can reduce the vibration and impact of wind on the wind plate, reduce the risk of damage to the turbine under extreme wind conditions, thereby extending its service life and further increasing the stability of the wind measurement of the device.

However, the existing wind measuring devices for wind power generation have poor stability. When the device encounters strong winds or extreme weather, the strong winds will cause the anemometer and wind vane in the wind measuring device to swing or vibrate greatly, thereby affecting the accuracy of the measurement.

This airfoil can reduce the vibration and impact of the wind on the wind plate 27, reduce the risk of damage to the turbine under extreme wind conditions, thereby extending its service life and further increasing the stability of the wind measurement of the device. In the device, a wind vane 214 and a power-assisted tail wing 215 are installed on the upper surface of the end connecting the auxiliary rod 213. Through the design of the wind vane 214 and the power-assisted tail wing 215, when the wind blows, one end of the power-assisted tail wing 215 that produces greater resistance to air flow will rotate downwind, thereby displaying the wind direction. This function is the most basic function of the device, and the wind direction can be observed more directly. The wind vane 214 and the power-assisted tail wing 215 are connected to the measuring device body 21 and The second measuring device 25 is integrated into the same device, which can avoid erroneous data caused by slight deviations between wind vanes and anemometers at different positions.

A lifting rod 216 is installed under the mounting rod 1, and the lifting rod 216 can be adjusted according to actual needs, which means that the wind measuring device can be placed at different heights to meet different meteorological observation needs. The design of the lifting rod 216 makes the deployment, adjustment and maintenance of the device relatively simple, thereby improving work efficiency. Four supporting legs 217 are installed at the end of the lifting rod 216, and the supporting block 218 is a columnar structure, which can support the device.The inner side of the end of the support leg 217 is fixedly connected with a support block 218.
