Abstract

The utility model belongs to a generating mechanical device by means of wind power and provides a wind adjustable vertical shaft wind-driven engine, mainly comprising a vertical rotation shaft, a dead axle, a vertical wing, a slip-ring, a wing adjusting bar, a tail, etc. The vertical wing of the wind-driven engine rotates over the vertical shaft and always keeps the best attack angle with the relative wind direction by means of the slip-ring and the wing adjusting bar. The utility model has the advantage of increasing the energy conversion efficiency of the wind-driven engine.

Description

Wind adjustable vertical shaft wind-driven engine

The utility model belongs to a kind of mechanical device that utilizes wind-power electricity generation.

Simple in structure, characteristics such as cost is low, easy-maintaining that the vertical axis wind machine has.But as generating usefulness, 100 kilowatts of must have of especially the type of the above networking operation of bigger high speed property coefficient, to simplify gearbox.This horizontal-shaft wind turbine of will suing for peace is the same, adopts the lift-type fin.The lift that present hard-wired upright shaft wind motor fin produces on each position that rotates a circle, its size and Orientation changes.For improving energy conversion efficiency, apparent wind is to keeping the suitable angle of attack constantly to fin.

The purpose of this utility model just provides a kind ofly can reconcile apparent wind to the angle of attack to the vertical wing automatically in rotary course, increase running torque, improves the vertical axis wind machine of energy conversion efficiency.

The utility model pivotal axis is transferred the aerofoil profile wind energy conversion system automatically, and its overall structure is shown in accompanying drawing one.(1) is vertical rotating shaft among the figure; (2) the vertical wing of lift-type; (3) transverse arm; (2) with (3) but the connection place moving.(4) adjusting wing rod; (4) be fixed on (3) by axle sleeve and strut.Its length is fixed, but move left and right, and be articulated in loosening state on the little axle of leading edge of (2).(5) spring; (6) pulley; (7) slip ring; (5) can make (6) to be close to (7) all the time, the track edges in (7) outside by (4) (2) are kept and apparent wind to the best angle of attack.(8) supporting rib; (9) movable axle sleeve; (10) dead axle; (11) end, sat; (7) be fixed on (9) by (8), (11) connect pylon; (12) empennage; (12) be fixed on (9).(13) generator support; Be fixed on (10).(14) generator; (15) driving gear; (15) be fixed on (1) and go up and drive the gear rotary electrification of (14).(16) fixed axle sleeve; (16) there is a hole that power line is passed through on and arrives ground.

The working principle that goes up fast vertical axis wind machine is: empennage (12) points to by wind direction to be determined.Slip ring (7) is fixed on (9) by (8), reaches the angle that changes track edges with (12).(7) track is after wind direction is fixing, vertically the wing (2) each point in a week residing with apparent wind when becoming the best angle of attack, the leading edge of (2) is by the length and the pulley (6) of (4), the surface of lucky arrival (7) and definite.Spring (5) can make adjusting wing rod (4) and be fixed on pulley (6) on (4) near slip ring (7), when roll on the side of (7) (6), vertically the wing (2) and apparent wind to the angle of attack be definite by the track of slip ring (7) side, reach the each point of the vertical wing in a week and remain optimum embedding angle.

Wind energy conversion system provided by the utility model, its rotating shaft, structure rotating shaft shown in accompanying drawing two (1) of dead axle part is fixed in dead axle (10) inside by bearing (18), (19), can rotate freely.Empennage (12) is fixed on the movable axle sleeve (9), and (9) rotate around fixed axle sleeve (16). (16) be fixed on (10), on a hole is arranged, the power line that can make (14) is by so that arrive ground. (17) be fixed on the slip ring on (16), on the contact surface of (16), slide simultaneously so that (9) when rotated. (13) be fixed on and be used for support motor (14) on the dead axle (10), .1 kilowatt of left and of and drive generating by the gear (15) that is fixed on (1) right sides type as than, more than 15 meters, 100 kilowatts of as rotating of output power reaches the type of the above networking operation of diameter, then motor and gearbox can be installed on the ground, promptly easy again for ease of maintenaince.

15 ° of of of relatively.The excessive of Accompanying drawing three is trajectory shapes of vertical wing optimum embedding angle that each point should be in a week and slip ring (7) .The V wind direction should can produce maximum lift to the merit angle of vertical chord line about angle of attack can produce stall, and lift descends and increases resistance.F lift among the figure, V wind speed, 100 kilowatts of for example of ω chi tip speed.The type about, its vertical chord line will be about 700mm, about the perpendicular distance 300mm of adjusting wing rod and transverse arm, and 1 meter of slip ring diameter, then track depart from generating circle (inwardly or outwards) the solstics about 80mm, pulley can move on this track fully evenly.

This machine speed limit can adopt the air disturbance device.When rotating speed surpasses a certain limit, flow spoiler opens and starts working under action of centrifugal force, to keep the fixed rotating speed of blower fan.

Claims

1, a kind of adjustable aerofoil profile wind-driven generator of pivotal axis that constitutes by the vertical wing, vertically rotating shaft, empennage etc., it is characterized in that: vertically nose of wing is adorned an adjusting wing rod (4) of being furnished with spring, adjusting wing rod is installed a pulley (6) by vertical rotating shaft end, this pulley tightly moves along slip ring (7) under the effect of spring.The side track of slip ring (7) is by the adjusting wing rod (4) of fixed length the leading edge distance during the each point optimum embedding angle and decision in the vertical wing rotates a circle.

2, by the wind energy conversion system described in the claim 1, it is characterized in that: slip ring (7) is fixed on the movable axle sleeve (9), and axle sleeve (9) links to each other with empennage (12), by axle sleeve (9) the slip ring direction is changed with empennage.
