New wind Power Bridge based on double rotor wind turbine

In order to make full use of the valley winds in the western region and the ocean winds in the southeast coastal areas, and to broaden the application of wind power, we have designed a new wind power bridge technology based on dual-rotor wind turbines. This program relies on the bridge structure and makes full use of the wind field where the bridge is located to generate electricity. Install an innovative double-rotor fan on the bridge, which can greatly improve the wind energy utilization coefficient, and provide more uniform force to the bridge than the general fan to ensure the safety of the bridge; small and medium-sized wind turbines without a yaw mechanism are installed under the bridge. The high wind speed generated by the natural narrow tube effect of the bridge support structure improves the power generation efficiency, and connects the charging coil for the small fan, which provides support for the wireless charging technology of the electric vehicle in the future, and realizes the immediate use of the electric energy. 1. Development background and significance At present, wind power generation has become the third largest form of power generation in China. The Outline of the National Mediumand Long-Term Science and Technology Development Plan states that “the proportion of renewable energy in China's energy consumption will reach 16% in 2020“ [1], and the use of wind power generation has broad research space and development prospects. However, a large number of high-quality wind farms in China have been developed and utilized, and the annual average wind speed of the remaining wind farms is unsatisfactory. China's wind power has officially entered a transition period. The current wind power industry is in desperate need of an ideal wind farm capable of arranging wind turbines over a large area. Therefore, we have turned our sights on bridges with natural “stubbing effects“. The bridge is generally constructed in the shortest distance between the two land areas. The axial cross-sectional area is the smallest. The natural narrow tube effect is formed before and after the bridge, which increases the average wind speed and forms a high-quality natural wind field. On the bridge deck, we designed the dual-rotor wind turbine into the bridge support structure, effectively utilizing the bridge wind speed, on the one hand sharing the basic structure with the bridge, saving consumables, and preventing the bridge from being fixed in one-way force, slowing down The fatigue damage of the bridge increases the stability of the bridge; on the other hand, the dual-rotor wind turbine has high power, high utilization of wind energy and large annual power generation. Below the bridge deck, a small fan is integrated into the bridge bracket to make full use of the idle space to generate electricity. Not only does energy are used effectively, but it also adds to the beauty of the bridge. Promote wind power bridges, on the one hand, increase the source of power supply, improve the grid-connected capacity of wind power, alleviate the shortage of power supply in some areas, effectively reduce the cost of electricity, and achieve efficient resource allocation. On the other hand, reducing the use of oceans, weakening the impact on marine life, facilitating the maintenance of the unit, adding new forms of wind farm construction, providing new directions for future development of wind power buildings, contributing to better wind power generation. The alternative to traditional thermal power generation to achieve sustainable social development. 2019 7th International Conference on Machinery, Materials and Computing Technology (ICMMCT 2019) Published by CSP © 2019 the Authors 121
