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

A kind of vertical axis windmill that has wind-gathering device
Technical field
The invention belongs to the wind power plant field, a kind of vertical axis windmill that has wind-gathering device particularly is provided.
Background technique
Countries in the world all are faced with the dual-pressure of conventional energy resource shortage and environmental protection.Renewable energy power generation obtains development and application at full speed in recent years, has played important effect to alleviating current energy pressure.Wind-power electricity generation is with fastest developing speed a kind of in the various renewable energy sourcess, and recent two decades is with 30% speed increment every year on average.The wind-driven generator of main flow all adopts the wind energy conversion system of horizontal axis at present, and its reason is that the efficient of vertical axis windmill is relatively low.But vertical axis windmill also has many good qualities, if can be apt to add utilization, will inject new vitality for the wind-powered electricity generation development.General vertical axis windmill is in the blade of the both sides of axle respectively in the direction of facining the wind, and the moment direction that acts on behind the wind-engaging on the axle is opposite, thereby cancels each other, and causes the Wind Power Utilization effect bad.In addition, the density of wind energy itself is lower, and using also has a lot of inconvenience.
Summary of the invention
The present invention is directed to the deficiency of existing wind generating technology, a kind of vertical axis windmill that has wind-gathering device is provided.It is characterized in that, funnel shaped wind-gathering device 2 is set, make and have only the wind wheel 4 direct wind-engaging just that can continue to provide power for vertical axis windmill 1 at the windward side of vertical axis windmill 1, and the wind wheel 4 of giving vertical axis windmill 1 manufacturing resistance wind-engaging not.
The structure of described vertical axis windmill 1 is: 2 or 2 above wind wheels 4 evenly are set on vertical shaft 3.
The shape of described wind wheel 4 comprises circle, S shape, scoop.
The intake grill of described wind-gathering device 2 is big, and air-out is young, is funnel shape, and its effect is will originally form the wind of resistance to be directed to vertical axis windmill 1 and to provide on the wind wheel 4 of power.
Beneficial effect of the present invention is: wind-gathering device has improved the wind energy density that utilizes, thereby has improved the power of whole wind machine; Wind energy only provides power, and the resistance of not making has overcome the weakness of vertical axis windmill maximum, and the efficient of vertical axis windmill is improved.
Description of drawings
Fig. 1 is the schematic representation of vertical axis windmill of the present invention;
Fig. 2 is the front view of wind-gathering device among the present invention;
Fig. 3 is the plan view of wind-gathering device among the present invention;
Fig. 4 is for having the vertical axis windmill principle schematic of wind-gathering device among the present invention.
Number in the figure:
The 1-vertical axis windmill; The 2-wind-gathering device; The 3-vertical shaft; The 4-wind wheel.
Embodiment
The invention provides a kind of vertical shaft fan that has wind-gathering device, the present invention will be further described below by description of drawings and embodiment.
Fig. 1~Fig. 4 is the vertical shaft fan structural representation of vertical axis windmill, wind-gathering device and band wind-gathering device.2 plate shapes evenly are set on vertical shaft 3 are circular wind wheel 4, constitute vertical axis windmill 1; Be provided with at the windward side of vertical axis windmill 1 that intake grill is big, air-out is young is funnel shaped wind-gathering device 2, make and to have only the wind wheel 4 direct wind-engaging just that can continue to provide power for vertical axis windmill 1, and the wind wheel 4 of giving vertical axis windmill 1 manufacturing resistance wind-engaging not.
Wind-gathering device draws large-area wind in the passage that narrows down gradually, concentrates the blade that blows to wind energy conversion system, improves the power of wind energy conversion system.And, with originally forming the wind of resistance, also be directed to the blade that power is provided, when avoiding making resistance, also increased power.
