Novel lift-to-drag combination H-S type vertical shaft wind machine

Abstract

According to one aspect of the invention, a novel lift-to-drag combination H-S type vertical shaft wind machine is provided. The novel lift-to-drag combination H-S type vertical shaft wind machine is characterized in that a vertical shaft H type resistance wind machine (1) and a spiral blade S type lift force wind machine (2) arranged in the center of the H type resistance wind machine are included. The novel lift-to-drag combination H-S type vertical shaft wind machine has the advantages of being capable of starting at low wind speed and not being influenced by the incoming current wind direction. Consequently, the wind energy utilization rate of the vertical shaft wind machine is improved. The novel lift-to-drag combination H-S type vertical shaft wind machine is more suitable for habitants in areas where wind speed is low and wind direction uncertainty is large.

Description

technical field [0001] The invention mainly combines the helical blade S-type resistance wind turbine and the vertical axis H-type lift wind turbine together, so that the wind turbine can be started at low wind speed and is not affected by the incoming wind direction, thereby improving the wind energy of the wind turbine. usage efficiency. Background technique [0002] As we all know, energy is the lifeblood of national economic development. With the emergence of more and more serious environmental pollution problems and the deepening of the double crisis of the limited reserves of fossil fuels, the development and utilization of renewable energy has become extremely urgent for human beings. Among the many renewable energy sources that can be developed and utilized ( That is, new energy, mainly including wind energy, solar energy, biomass energy, tidal energy, etc.), wind energy has become an important part of the current world energy structure due to its large reserves, wi...

Problems solved by technology

[0003] The H-type lift wind turbine is a typical lift-type vertical axis wind turbine. It first appeared in France in the 1930s. The ability to capture wind energy is favored by people, but this kind of wind turbine has a relatively high starting wind speed, and it is difficult to start at a lower wind speed, and when the incoming wind direction is in some cases, it is difficult to start the wind turbine. That is, this kind of wind turbine has a relatively high dependence on wind direction, which affects the use of this vertical axis wind turbine in areas with low wind speed and large wind direction changes.
