Slide rail type multi-level vertical wind power generation device

Abstract

The invention discloses a slide rail type multi-level vertical wind power generation device. The slide rail type multi-level vertical wind power generation device comprises a base, annular supports and multiple sets of power generation units. The base and the multiple sets of power generation units are arranged in the annular supports. The multiple sets of power generation units are sequentially connected in series from bottom to top through transmission boxes. Each power generation unit comprises multiple support arms, an impeller shaft and vanes fixed to the support arms. The multiple support arms are distributed in the circumferential direction of the corresponding impeller shaft in a radial manner. A guide wheel is arranged at the end, away from the corresponding impeller shaft, of each support arm and extends horizontally to the top face of the corresponding annular support. Each support arm can slide along the corresponding annular support with the corresponding impeller shaft asthe circle center. Subsidiary electric generators are fixed to two sides of each support arm. Rotors of the subsidiary electric generators are in the same direction with the radial direction of the corresponding annular support. Circular blocks are fixed to ends of the rotors. The circular blocks are in sliding connection with the top faces of the annular supports. Support rods extending to the ground are fixed to the outer side faces of the annular supports. The power generation unit located at the very bottom is connected with the base through a bearing. The slide rail type multi-level vertical wind power generation device has better stability and wind resistance; and in the meantime, the device has the function of multi-level power generation, and power generation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a sliding rail type multi-stage vertical wind power generation device. Background technique [0002] The available resources on the earth are decreasing day by day. Today, with the increasing awareness of environmental protection, the utilization and development of renewable energy has been paid more and more attention by various countries due to the characteristics of clean energy and low greenhouse gas emissions. Among them, solar power generation and wind power generation are the most important. [0003] Wind turbines are distinguished by the direction of the impeller rotation axis, and there are two types: horizontal axis type and vertical axis type. At present, in the domestic and foreign markets, the horizontal axis wind turbine is still the mainstream form. However, horizontal axis wind turbines have significant disadvantages. For example, the horizontal a...

Problems solved by technology

When the height of the blade increases, the wind resistance of the blade becomes worse, and it is necessary to increase the shaft size of the blade and strengthen the support of the shaft; in this way, the weight and manufacturing cost of the fan blade are correspondingly increased, and the requirements for the support shaft are also increased. Increased, the installation is also more difficult, moreover, when the multi-layer blades rotate at the same time, the centrifugal force generated is relatively large, which is easy to cause damage to the impeller shaft

From the above, it can be seen that under the condition of ensuring sufficient wind receiving area, how to ensure that the vertical blades of the vertical axis wind turbine are stably arranged on the vertical axis is a challenge faced by the design, manufacture and installation of the blades of the large power vertical axis wind turbine. There is still no better solution to the key problem, and especially on some islands, due to the strong wind, the whole device is underweight and easily blown over, causing unnecessary losses
