Problems solved by technology

In general vertical axis wind turbines, the blades on both sides of the shaft in the windward direction, the direction of the torque acting on the shaft after receiving the wind is opposite, so they cancel each other out, resulting in poor wind energy utilization.
In addition, the density of wind energy itself is low, and it is inconvenient to use it.

Embodiment Construction

[0014] The present invention provides a vertical-axis fan with a wind gathering device, and the present invention will be further described below through the description of the drawings and specific embodiments.

[0015] Figure 1 ~ Figure 4 It is a structural schematic diagram of a vertical axis wind turbine, a wind collecting device, and a vertical axis fan with a wind collecting device. Two circular wind wheels 4 are evenly arranged on the vertical axis 3 to form a vertical axis wind turbine 1; a funnel-shaped wind collecting device 2 with a large air inlet and a small air outlet is arranged at the windward end of the vertical axis wind turbine 1 , so that only the wind rotor 4 that can continuously provide power for the vertical axis wind turbine 1 is directly exposed to the wind, while the wind rotor 4 that creates resistance for the vertical axis wind turbine 1 is not affected by the wind.

Abstract

The invention belongs to the field of wind power generating equipment, and more particularly provides a vertical axis wind turbine provided with a wind collecting device. The windward end of the vertical axis wind turbine is provided with the funnel shaped wind collecting device to lead a wind wheel which can continuously provide power for the vertical axis wind turbine to directly receive wind, while a wind wheel that causes resistance for the vertical axis wind turbine can not receive wind. The wind collecting device improves the utilized wind energy density, thereby increasing the power of the whole wind machine; as the wind only provides power and does not cause resistance, the biggest weak point of the vertical axis wind turbine can be overcome, and the efficiency of the vertical axis wind turbine can be improved.

Description

technical field [0001] The invention belongs to the field of wind power generation equipment, and in particular provides a vertical axis wind machine with a wind collecting device. Background technique [0002] All countries in the world are facing the dual pressure of conventional energy shortage and environmental protection. In recent years, the rapid development and application of renewable energy power generation has played a very important role in alleviating the current energy pressure. Wind power is one of the fastest growing renewable energy sources, with an average annual growth rate of 30% in the past two decades. At present, the mainstream wind turbines all use horizontal-axis wind turbines. The reason is that the efficiency of vertical-axis wind turbines is relatively low. However, the vertical axis wind turbine also has many advantages. If it can be utilized properly, it will definitely inject new vitality into the development of wind power. In general vertic...
