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

A kind of novel liter resistance combination H-S type vertical axis windmill
Technical field
The present invention is combined helical blade S form-drag wind energy conversion system and vertical shaft H type lift Wind turbine, thereby wind energy conversion system just can be started at low speed wind speed, and is not subject to the impact of incoming flow wind direction, and then has improved wind energy conversion system wind energy utilization efficiency.
Background technique
As everyone knows, the energy is the lifeblood of the national economic development.Along with the appearance of more and more serious environmental pollution problem and the intensification day by day of the fossil Double jeopardy that so the limited reserves of material reduce, the mankind become incomparable urgent to the development and utilization of renewable energy sources, in numerous renewable energy sourcess that develop, (be new energy, mainly contain wind energy, solar energy, biomass energy, tidal energy etc.) in, wind energy is large with its reserves, widely distributed relative with development technique ripe and become an important component part in current world energy sources structure, EWEA and international green peace organization just make bold prediction the beginning of this century, expecting 12% of the year two thousand twenty whole world power supply will be from wind energy.
H type lift wind energy conversion system is typical lift vertical shaft wind energy conversion system, 30 years of last century appear at France the earliest, its leaf cross-section is aerofoil profile, this just makes this wind energy conversion system under suitable wind speed, can have a good wind energy capturing ability, thereby extremely people's favor, but this wind energy conversion system is larger at startup wind speed, just more difficult startup under lower wind speed, and work as incoming flow wind direction in some cases, wind energy conversion system is just difficult to start, namely this wind energy conversion system is higher to the dependence of wind direction, this has just affected the use of this vertical axis windmill and wind vector larger area lower at wind speed.
Summary of the invention
It is larger that traditional H type lift wind energy conversion system starts wind speed, just more difficult startup under lower wind speed, and start also greatlyr to the dependence of wind direction, affected the use of this vertical axis windmill and wind vector larger area lower at wind speed.For this reason, we wish, by for rising the mode of resistance combination, to reduce the starting torque of this wind energy conversion system, and then expand its application area.
According to one embodiment of present invention, in vertical shaft H type lift-type wind energy conversion system central authorities, add a helical blade S form-drag type wind energy conversion system, thereby lift-type and shaft resistance type windmill are combined, when wind speed is lower, the S form-drag wind energy conversion system of central authorities just can start, and then drive H type wind energy conversion system to rotate, and the startup of helical blade S form-drag wind energy conversion system is not subject to the restriction of wind direction, the shaft resistance type windmill of central authorities has played an assistant starting, so just low speed wind speed can be difficult to start and problem that wind direction dependence is large to having solved; When wind speed is higher, H type wind energy conversion system just can independently rotate seizure wind energy.
According to an aspect of the present invention, provide a kind of liter resistance combination H-S type vertical axis windmill, it is characterized in that comprising:
A vertical shaft H form-drag wind energy conversion system,
Be arranged on a helical blade S type lift wind energy conversion system of described H form-drag wind energy conversion system central authorities.
Beneficial effect of the present invention comprises, wind energy conversion system just can start under lower wind speed, and is not subject to the impact of incoming flow wind direction, thereby has improved the wind energy utilization efficiency of vertical axis windmill, is more suitable for wind speed resident lower and wind direction indeterminedness larger area and uses.

Embodiment
Referring to Fig. 1, a kind of novel liter resistance combination H-S type vertical axis windmill according to an embodiment of the invention comprises:
At traditional H type lift wind energy conversion system (1),
Central authorities at traditional H type lift wind energy conversion system (1) add a helical blade S form-drag wind energy conversion system (2) of putting.
H type lift wind energy conversion system (1) is coaxial with S form-drag wind energy conversion system (2).
For example, in one embodiment of the invention, the height of helical blade S form-drag wind energy conversion system (2) is 1.48m, and rotating diameter is 0.66m, and spiral angle is 180 °, and the rotating diameter of H type wind energy conversion system (1) is 2.64m.。
Referring to Fig. 2, the rotating diameter of the central S form-drag wind energy conversion system (2) of a kind of novel liter resistance combination H-S type vertical axis windmill according to an embodiment of the invention is about 1/4th of H type lift wind energy conversion system (1) rotating diameter, in order to make the wind energy capturing ability of wind energy conversion system better, according to an embodiment's H type lift wind energy conversion system, there are four blades.
Referring to Fig. 3, wherein label 1 represents H type lift wind energy conversion system, and label 2 represents helical blade S form-drag wind energy conversion system, and label 3 represents pylon, and label 4 represents base.
When wind speed is lower, the S form-drag wind energy conversion system (2) of central authorities just can start, and then drive H type lift wind energy conversion system (1) to rotate, this has just solved the low wind speed of traditional H type lift wind energy conversion system (1) and has been difficult to the problem starting, and the startup of helical blade S form-drag wind energy conversion system (2) is not subject to the restriction of wind direction, played the effect of an assistant starting, so the startup of novel liter resistance combination H-S type vertical axis windmill is not just subject to the restriction of wind direction yet; And when wind speed is higher, H type lift wind energy conversion system (1) just can independently rotate seizure wind energy, therefore this novel liter resistance combination H-S type vertical axis windmill application area is wider.
