The sail type wind power device that the purpose of this invention is to provide a kind of novel structure.This invention makes the paddle of traditional wind force device into the plane sail, thereby its blowing area is increased greatly, increases Wind Power Utilization efficient, and its manufacturing process is simple, uses, safeguards also very convenient, can make in common middle-size and small-size machine works and produce, for apply provide may and market.
The present invention is achieved in that and includes sail, vertical shaft, coupling, support and generator; Be fastened on the vertical shaft at the axle sleeve of radially equally distributed 3~4 vertical sails on the vertical shaft by the one side, the vertical shaft bottom is fixed on the Steel Support by radial-thrust bearing, links to each other with generator or drive unit by coupling in the lower shaft end of vertical shaft; Wherein form in order to it is fastened on by axle sleeve on the vertical shaft and several rows of 100 o'clock window assemblies in the framework by the framework of rectangular shape, framework one side for sail, wherein each blade single-piece two ends all has a bearing pin to be used for hinge to be contained in the framework, and can to freely swing with bearing pin; It is characterized in that: a side of sail framework be equipped with one on it with the corresponding adjusting screw rod of each leaf position, in order to adjust the sealing angle of each blade.
Can set up the frame structure of gantry frame type, in order to the last axle head of supporting vertical shaft.
The present invention is relatively simple for structure, and the calculating of its sail does not resemble the propeller complicated, can select the area of sail according to the wind resource grade of locality, the watt level of institute's driving generator at an easy rate, and its manufacturing process is not difficult yet, and cost is cheaper.Because it is all very convenient that this appliance arrangement is installed in ground, mounting, commissioning and maintenance, do not need special structure stand yet, greatly reduce cost, topmost characteristics then are that blowing area is all bigger than the blade of the wind force device of other any kinds, like this, even also the present invention can be installed in the area that wind resource is very weak, wind resource is fully used.It is calculated that 1 kilowatt-hour of wind-power electricity generation of every use just is equivalent to discharge less 1 kilogram of carbon dioxide in atmosphere.Penetration and promotion of the present invention is a Gospel for improving environment for human survival.
Fig. 1 is that structure of the present invention is formed schematic representation.
Fig. 2 is that the structure of another embodiment of the present invention is formed schematic representation.
Structure of the present invention includes sail 1, vertical shaft 2, coupling 6, support 5 and generator 7.The wind apparatus that is subjected to of the present invention is radially equally distributed 3~4 sails that vertical sail 1 is formed on vertical shaft 2, sail 1 is fastened on the vertical shaft 2 by the axle sleeve 3 of one side, vertical shaft 2 bottoms are fixed on the Steel Support 5 by radial-thrust bearing 4, lower shaft end at vertical shaft links to each other outputting power by coupling 6 with generator 7 or drive unit.Form in order to it is fastened on by axle sleeve 3 on the vertical shaft 2 and the several rows of louver assembly 10 in the framework by the framework 9 of rectangular shape, framework one side for sail 1, wherein each blade single-piece two ends all have a bearing pin be used for the hinge be contained in the framework 9 so that blade can freely swing with bearing pin.And a side of framework 9 be equipped with one on it with each corresponding adjusting screw rod 11 in blade 10 positions, in order to adjust the sealing angle of each blade.
Sail 1 is to be installed on the vertical shaft 2 also fastening with screw by axle sleeve 3.This sail makes lifting surface area greatly increase than the paddle of propeller formula.On vertical shaft, can radially evenly place 3~4 sails.The valve plate of the several rows of blade assembly 10 similar one-way valves in the rectangular frame 9 of each sail is the same, when wind when the stress surface of sail blows, each blade on this sail is all in the closed position, the sail wind-engaging blows and rotates around vertical shaft.When sail was in against the wind to the position, this moment, blade all was in the enable possition, and the blade of wind from sail penetrates and mistake, sail and do not stress (or stressed very little).Blade 10 on the sail is adjusted the angle of its switching by the adjusting screw rod 11 of one side.Because the sail on the wind wheel is all installed with the same manner, therefore, no matter wind direction is from where, sail all promotes the vertical shaft rotation along a direction, and this kinetic energy reaches generator 7 or drive unit by coupling 6, produces electric energy or outputting power.
