Description
Technical field
The invention belongs to wind energy conversion system technical field, relates generally to a kind of floated vertical axis windmill.
Background technique
Along with the minimizing of non-renewable energy resources and the enhancing of environmental protection consciousness, the renewable and wind energy development of non-environmental-pollution utilizes and becomes development trend, and namely wind energy conversion system is one of them.At present, wind energy conversion system is mainly divided into horizontal axis and vertical axis windmill two kinds.Relative to horizontal-shaft wind turbine, vertical axis windmill has more superior technical feature, and therefore, vertical axis windmill research and development utilize and become following development trend.But, because large-scale vertical axis windmill build is huge, quality is heavy, larger load is brought to the passive bearing of vertical axis windmill, support and base, during wind energy conversion system rotation operating mode, mechanical friction is comparatively large, except bringing parts wear, reducing except working life, also reduces wind energy utilization simultaneously, cause wind energy loss to waste, reduce operation effectiveness.For solving the problem, the existing research utilizing magnetic suspension bearing and crossbeam to adopt airfoil structure two kinds of vertical axis windmills, but the former cost is high, complex structure, and the angle of attack windward of the latter's crossbeam is non-adjustable, and the ability producing lift effect is poor.
Summary of the invention
The object of the invention is exactly for above-mentioned prior art Problems existing, in conjunction with practical operation situation, design provides a kind of floated vertical axis windmill of new structure, by installing lift unit additional on vertical axis windmill crossbeam, reaching to reduce when wind energy conversion system runs and offset and be carried in weight on bearing, alleviate parts wear, prolonged mechanical working life, improve the object of wind energy utilization.
The object of the invention is achieved in that a kind of floated vertical axis windmill, undersetting is fixedly mounted with bearing housing, by lower bearing and upper bearing (metal) equipped vertical shaft rotationally on bearing housing, top bearing cover is fitted on bearing housing upper end portion, on the vertical axis from top to bottom by upper flange and lower flange equipped upper beam and bottom end rail respectively, pneumatic equipment blades made is fitted in, on bottom end rail outer end, undersetting installs master controller, equipped lower pressure sensor is supported between undersetting top and bearing housing bottom, equipped upward pressure sensor is supported between bearing housing upper end portion and top bearing cover, stepper motor and controllor for step-by-step motor are packed on lower flange, and be communicated with by wire, two cross blade supports fit on bottom end rail admittedly, the cross blade two end part of symmetrical airfoil are fixedly mounted with respectively on cross blade back shaft, stepper motor is connected with cross blade by cross blade controlling angle driving mechanism, described upper and lower pressure transducer is communicated with master controller respectively by wire, master controller and controllor for step-by-step motor wireless communications.
The invention utilizes the blade rotated to produce lift and can change by the angle of attack windward controlling blade the principle that it produces lift size, the lift of cross blade and the relation of wind energy conversion system gravity is judged by the pressure difference of detection axis bearing sleeve upper/lower terminal, make any time of wind energy conversion system within the scope of rated revolution can be the gravity that lift offsets wind energy conversion system by the angle of attack of constantly finely tuning cross blade, ensure that it works under state of suspension.The feature of the invention is: effectively avoid because gravity makes wind energy conversion system operationally produce larger mechanical friction, reduce and even avoid wind energy conversion system to the bearing supported and support, base build-up of pressure load, life-saving, also can improve wind energy utilization simultaneously, increase generating efficiency.

Embodiment
Below in conjunction with accompanying drawing, the invention embodiment is described in detail.
A kind of floated vertical axis windmill, undersetting 1 is fixedly mounted with bearing housing 3, by lower bearing 4 and upper bearing (metal) 6 equipped vertical shaft 5 rotationally on bearing housing 3, top bearing cover 8 is fitted on bearing housing 3 upper end portion, from top to bottom by upper flange 10 and lower flange 9 equipped upper beam 11 and bottom end rail 16 respectively on vertical shaft 5, pneumatic equipment blades made 12 is fitted in, bottom end rail 11, on 16 outer ends, at undersetting (1) upper installation master controller 20, equipped lower pressure sensor 2 is supported between undersetting 1 top and bearing housing 3 bottom, equipped upward pressure sensor 7 is supported between bearing housing 3 upper end portion and top bearing cover 8, stepper motor 18 and controllor for step-by-step motor 19 are packed on lower flange 9, and be communicated with by wire, two cross blade supports 13 fit on bottom end rail 16 admittedly, cross blade 15 two end part of symmetrical airfoil are fixedly mounted with on cross blade back shaft 14 respectively, stepper motor 18 is connected with cross blade 15 by cross blade controlling angle driving mechanism 17, described upper and lower pressure transducer 7,2 is communicated with master controller 20 respectively by wire, master controller 20 and controllor for step-by-step motor 19 wireless communications.
Described cross blade controlling angle driving mechanism 17 is made up of leading screw 21, rack nut 22, cylindrical gears 23, worm screw 24 and worm gear 25, described rack nut 22 can axially movably be fitted on leading screw 21, leading screw 21 is connected with stepper motor 18, described worm gear 25 is packed on cross blade back shaft 14, described cylindrical gears 23 fits on worm screw 24 admittedly, and cylindrical gears 23 engages with the tooth-strip part of rack nut 22, worm screw 24 engages with worm gear 25.
During use, when floated vertical axis windmill is not when reaching rated operation, the angle of attack windward of cross blade 15 is 0 °, and because it is symmetrical airfoil, now lift is close to zero, and suspension system does not work.When wind energy conversion system reaches rated operation, lower pressure sensor 2 and upward pressure sensor 7 are started working, the pressure at detection axis bearing sleeve 3 two ends, and testing result is transferred to master controller 20 and analyzes, when bearing housing 3 low pressure is greater than upper pressure, gravity is greater than lift, master controller 20 assigns instruction by wireless connections to controllor for step-by-step motor 19, controllor for step-by-step motor 19 control step motor 18 works, and the angle of attack windward of cross blade 15 is increased by cross blade controlling angle driving mechanism 17, increase the lift of suspension system.When bearing housing 3 low pressure is less than upper pressure, gravity is less than lift, master controller 20 assigns instruction by wireless connections to controllor for step-by-step motor 19, controllor for step-by-step motor 19 control step motor 18 works, and the angle of attack windward of cross blade 15 is reduced by cross blade controlling angle driving mechanism 17, reduce the lift of suspension system.
