Combined generating device with multiple wind driven generators

Abstract

The invention relates to a combined generating device with multiple wind driven generators, comprising a pole and multiple horizontal axis wind driven generators (1). The device is characterized in that the pole comprises an upper pole (2) and a lower pole (3); the upper pole is coaxially installed at the top end of the lower pole and can rotate around own axis relative to the lower pole; the multiple horizontal axis wind driven generators are arranged at the same side of the upper pole at intervals along the height direction; and tail wings (4) are arranged at the other side of the upper pole, corresponding to the horizontal axis wind driven generators. The device has the following advantages: when the wind blows the tail wings, the tail wings drive the whole upper pole to rotate, thus ensuring the impeller of each horizontal axis wind driven generator to be vertical to the wind direction and effectively improving the working efficiency of each horizontal axis wind driven generator, at the same time, multiple horizontal axis wind driven generators are adopted, therefore, even if each horizontal axis wind driven generator has low power, the horizontal axis wind driven generators combined in parallel can generate power with high power, and the low-power horizontal axis wind driven generator can be started under the condition of lower wind speed.

Description

technical field [0001] The invention relates to a wind power generating device, in particular to a combined power generating device with a plurality of wind power generators. Background technique [0002] Wind power generation devices are relatively common power generation equipment at present, and high-power horizontal-axis wind power generation equipment has also been widely used. Horizontal-axis wind power generation equipment generally includes a tower pole fixed on the ground. A horizontally rotating gyrator, on which a horizontal-axis wind power generator is fixed. The wheel shaft on the horizontal-axis wind power generator is roughly horizontal, and the end of the wheel shaft is connected to a wind wheel. The wind wheel on the wheel shaft faces the airflow, and the wind blows the wind wheel Rotating, the wheel shaft also rotates, and then drives the power generation unit of the horizontal axis wind turbine to generate current. The tail of the horizontal axis wind turb...

AI Technical Summary

Problems solved by technology

High-power horizontal-axis wind power generation equipment has a high start-up wind speed and cannot be started at all

Therefore, it is difficult to achieve high-power power generation at low wind speeds, and high-power fans have complex structures, large blades, high manufacturing costs, and inconvenient maintenance.

However, the low-power horizontal axis power generation equipment has the defect of low power generation efficiency
