Description

Wind wheel structure of cylinder internal blade type perpendicular axle wind motor

The utility model belongs to a kind of improved wind mill wind wheel structure.

Existing vertical axis wind turbine rotor structure occupies the majority with three leaf loop-drive formulas, H type wind wheel structure.Leafy, single leaf of minority and streamline bodily form fan blade wind wheel structure are also arranged.Their aerodynamic characteristics depends primarily on length, area, shape and the number of wind wheel blade.Existing wind wheel structure will obtain more wind energy, mainly by increasing the diameter of wind wheel, has both increased length, the area of wind wheel blade.But rotor diameter is big more, and the technology difficulty of making wind wheel is big more, and the manufacture cost of wind wheel is high more, and the installation of wind wheel and maintenance are difficult more, and the Applicable scope of wind wheel is narrow more.

The purpose of this utility model is a kind of improvement vertical axis wind turbine rotor structure of design, it is different from existing any wind mill wind wheel structure, it has specific configuration and aerodynamic characteristics, can obtain bigger wind wheel rotary inertia and high rotational speed with less rotor diameter, the relative power output of wind wheel is increased, and make this wind wheel have firm, turn round safety, long service life simple in structure, the big remarkable advantage that waits of Applicable scope.

Design of the present utility model is such: wind wheel material selection aluminium alloy sheet is best, the wind wheel profile is oval tubular, vertical shaft is connected with the axis hole at cylinder two base plate centers, drum diameter is about 0.30～1.50 meter, the cylinder height is 1～3 times of drum diameter, 0.3～1.0 millimeter of wall thickness of cylinder.Equidistant stroke of 3～4 vertical lines on the cylinder periphery wall, vertical line length equals the cylinder height, cut barrel along vertical line, with the barrel of tangent line homonymy to the tube invagination, make the tabs cross section perpendicular to cylinder center's line, tabs promptly is an intra vane, wide 1/4th of the barrel dliameter that equals of intra vane, the long barrel height that equals.Get the thin plate same, its long barrel height that equals with the barrel material.It is wide to be wide 1.3 times of intra vane, making cross section is the wind-collection cover plate of camber line shape, wind-collection cover plate one long limit is fixedly covered on the outer tube wall that is connected to the tangent line opposite side, make another long limit of wind-collection cover plate be parallel to the broken line of intra vane, with the perpendicular distance of broken line be intra vane wide 2/3rds, wind-collection cover plate two minor faces link with triangular sheets and are fixed on the cylinder two base plate round edges, whole wind wheel is by cylinder, intra vane, wind-collection cover and axis hole are formed, aerodynamic force characteristics of the present utility model are: air-flow flows into cylinder from first wind-collection cover mouth, impact fan housing inwall and cylinder inner wall, and impact on the intra vane of second wind-collection cover inboard, flow out from leeward wind-collection cover mouth at last, air-flow work distance in cylinder is long, kinetic energy all is converted into wind wheel and rotates energy, when the air-flow that enters from first wind-collection cover mouth did not also all flow out cylinder, the wind-collection cover mouth that the next one turns to the upwind position flow to new air blast again, so the acting of this wind wheel is a process continuously.Though this rotor diameter is little, be subjected to the wind-force area bigger, thereby relative power output is bigger, can reach about 0.35 power coefficient.This wind wheel structure also is applicable to the water wheels structure of water turbine.

Advantage of the present utility model is: this wind wheel structure is small and exquisite firmly, and rotary inertia is bigger; Rotating speed is higher, and relative power output is bigger, the running stability and safety, long service life, can use continuously more than 20 years and need not repair replacing, the manufacturing of this wind wheel, simple installation easily gain the essentials, be suitable for penetration and promotion, this wind wheel Applicable scope broadness, excellent performance is installed in this wind wheel on the aircraft that travels, steamer, the vehicle, both resistance to motion can be reduced, also certain energy can be obtained or reclaim.If this wind wheel is installed on the super high rise building, but wind-power electricity generation can reduce the lateral thrust of high altitude stream to super high rise building again, alleviates its amplitude of fluctuation.If this wind wheel is installed on the suitable position of the aircraft that travels, steamer, vehicle, can reduce running resistance, recyclable again and obtain energy, also can improve the stability and the Security of travelling, because lateral airflow can produce bigger lateral thrust to the object of running at high speed, and force it to change direction of advance.The object of running at high speed also can be subjected to lateral resistance when turning, install the running condition that this wind wheel will help to improve mechanical object.
