Description
Technical field
The invention belongs to the 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, wind energy development utilization renewable and non-environmental-pollution becomes development trend, and wind energy conversion system is one of them.At present, wind energy conversion system mainly is divided into two kinds of horizontal axis and vertical axis windmills.With respect to horizontal-shaft wind turbine, vertical axis windmill has more superior technical feature, and therefore, the 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, the passive bearing of vertical axis windmill, support and base are brought to larger load, when wind energy conversion system rotates operating mode, mechanical friction is larger, except bringing parts wear, reducing working life, also reduced wind energy utilization simultaneously, cause wind energy loss waste, reduce operation effectiveness.For addressing the above problem, the existing research that utilizes magnetic suspension bearing and crossbeam to adopt two kinds of vertical axis windmills of airfoil structure, but the former cost is high, complex structure, and the angle of attack windward of latter's crossbeam is non-adjustable, and the ability that produces lift effect is poor.
Summary of the invention
The purpose of the invention is exactly the problem existed for above-mentioned prior art, in conjunction with practical operation situation, design provides a kind of floated vertical axis windmill of new structure, by on the vertical axis windmill crossbeam, installing lift unit additional, reach wind energy conversion system when operation reduce and offsets the weight that is carried on bearing, alleviate parts wear, the purpose of prolonged mechanical working life, raising wind energy utilization.
The purpose of the invention is achieved in that a kind of floated vertical axis windmill, be fixedly mounted with bearing housing on undersetting, be equipped with rotationally vertical shaft by lower bearing and upper bearing (metal) on bearing housing, top bearing cover is fitted on the bearing housing upper end portion, be equipped with respectively upper beam and bottom end rail by upper flange and lower flange from top to bottom on vertical shaft, pneumatic equipment blades made is fitted in, on the bottom end rail outer end, master controller is installed on undersetting, support equipped lower pressure sensor between undersetting top and bearing housing bottom, support equipped upward pressure sensor 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, on the cross blade two end part of symmetrical airfoil, be fixedly mounted with respectively on the cross blade back shaft, cross blade controlling angle driving mechanism is connected stepper motor with cross blade, 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 blade of the invention utilization rotation produces lift and can change by the angle of attack windward of controlling blade the principle that it produces the lift size, judge the relation of lift and the wind energy conversion system gravity of cross blade by the pressure difference that detects the bearing housing upper/lower terminal, it can be the gravity that lift is offset wind energy conversion system that the angle of attack by continuous fine setting cross blade makes any time of wind energy conversion system in the rated revolution scope, guarantees that it works under state of suspension.The characteristics of the invention are: effectively avoided producing larger mechanical friction because the gravity reason makes wind energy conversion system when working, reduce and even to avoid wind energy conversion system to the bearing that supports and support, base build-up of pressure load, life-saving, also can improve wind energy utilization, increase generating efficiency simultaneously.

Embodiment
Below in conjunction with accompanying drawing, the invention embodiment is described in detail.
A kind of floated vertical axis windmill, be fixedly mounted with bearing housing 3 on undersetting 1, be equipped with rotationally vertical shaft 5 by lower bearing 4 and upper bearing (metal) 6 on bearing housing 3, top bearing cover 8 is fitted on bearing housing 3 upper end portions, be equipped with respectively upper beam 11 and bottom end rail 16 by upper flange 10 and lower flange 9 from top to bottom on vertical shaft 5, pneumatic equipment blades made 12 is fitted in, bottom end rail 11, on 16 outer ends, at the upper master controller 20 of installing of undersetting (1), support equipped lower pressure sensor 2 between undersetting 1 top and bearing housing 3 bottoms, support equipped upward pressure sensor 7 between bearing housing 3 upper end portions 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, on cross blade 15 two end part of symmetrical airfoil, be fixedly mounted with respectively on cross blade back shaft 14, cross blade controlling angle driving mechanism 17 is connected stepper motor 18 with cross blade 15, 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.
