Abstract

A vertical shaft bilobed wind turbine which is an improvement of an existing vertical shaft wind turbine, is characterized in that a main shaft of a wind wheel drives a transmission shaft through the eccentric displacement of a pair of transmission gear wheels, in the middle section of each group of internal and external vanes, a connecting rod is used for connecting two vanes, a regulating steel rope, which controls the angle change and return of the two vanes, changes direction downwards through a pulley arranged on a flange, penetrates the center of the main shaft of the wind wheel and is connected with an elasticity mechanism on the bottom of a tower frame by a rotary drum, a slide drum and a pull rod with a spherical head. Thus, the wind turbine has simple a structure and high precision in speed regulation and can realize breaking stop of the wind wheel.

Description

Vertical shaft double leaf group wind energy conversion system

(1) technical field: the utility model is a kind of vertical shaft double leaf group wind energy conversion system that the nature wind energy transformation is become operable mechanical energy.

(2) background technique: existing vertical-shaft wind-power machine, the ubiquity starting torque is little, the problem of speed limit difficulty, at this problem, just made the improvement invention and obtained national patent by the applicant as far back as 1985, denomination of invention is: vertical axis windmill, the patent No. is: 85105331.9.In former scheme, the angle of blade, return are to adopt one group of spring assembly to realize, by practice, find that this structure has the following disadvantages: adjusting speed accuracy is not enough, are not easy to adjust and control, and its structure is also comparatively complicated.

(3) summary of the invention: the purpose of this utility model is that the vertical shaft double leaf group that a kind of speed regulating structure is simple, adjusting speed accuracy is high, be convenient to control wind energy conversion system will be provided.

The technical solution of the utility model is: existing vertical axis windmill is improved, it has pylon, two groups of above vertical vanes, every group of blade divides inside and outside two, every group of blade pass crossed the leaf arm sling and is contained on the flange plate, and flange plate transmission wind wheel main shaft also is contained on the pylon by plane bearing, bearing support; Be connected in the adjusting steel cable in internal lobe stage casing, its improvement is: a. wind wheel main shaft drives transmission shaft by the displacement of a pair of driving gear off-centre, thereby so that eccentric installation of transmission shaft guarantees that the adjusting steel cable can pass from the centre downwards; B. the stage casing of two blades inside and outside every group links to each other inside and outside blade with a connecting rod, and is to guarantee two blade synchronization angles, stressed also more reasonable; C. regulate steel cable and be by be contained on the flange plate the pulley break-in down, pass through to the rotating cylinder that is connected wind wheel main shaft lower end from the wind wheel alignment of shafts and to be connected with slide cartridge, round end pull bar passes slide cartridge, rotating cylinder to the pylon bottom, operate knob pull bar degree of tightness up and down by the thrust-bearing that is contained in the slide cartridge bottom, regulate steel cable, and under the centrifugal deflecting torque effect that blade produces when the wind wheel high speed rotating, outer leafs angle, return in can realizing, because how many degree of tightness mechanisms can according to the operating of wind speed round, so the adjusting speed accuracy height.

The utility model is simple in structure, and is easy to operate, is easy to control, the adjusting speed accuracy height, and can realize the wind wheel Brake stop.

(4) description of drawings: Fig. 1 is an overall structure schematic representation of the present utility model; Fig. 2 is inside and outside blade angle of the present utility model, return schematic representation.

Among the figure, the 1-outer leafs, the 2-intra vane, 3-regulates steel cable, the 4-pulley, 5-connecting rod, 6-rotating cylinder, 7-slide cartridge, the 8-thrust-bearing, 9-knob pull bar, 10-siphonal lobe support plate, 11-pin, 12-internal lobe support plate, 13-leaf arm, 14-lightning conductor, 15-flange plate, 16-wind wheel main shaft, 17-driving gear, 18-shaft joint, 19-transmission shaft, the 20-pylon, 21-plane bearing, 22-bearing support.

(5) embodiment: referring to Fig. 1, Fig. 2, the utlity model has in two groups, outer leafs (2,1), in, outer leafs (2) and (1) are by interior, outer leafs support plate (12) and (10) are hinged with pin (11) and leaf arm (13), leaf arm (13) is contained on the flange plate (15), flange plate (15) is by plane bearing (21), bearing support (22) is loaded on the pylon (20), lightning conductor (14) also is equipped with in the upper end of flange plate, the flange plate endoporus connects wind wheel main shaft (16), the a pair of gear of transmission (17) successively again, coupling (18), transmission shaft (19), the output torque drives working machine, as: generator, suction engine etc.

In the utility model, in every group, connecting rod (5) is equipped with at 1/2 place, stage casing of outer leafs, in making, outer leafs (2) and (1) interlock, regulate the front portion that steel cable (3) is connected internal lobe support plate (12), regulate steel cable (3) down by pulley (4) break-in, pass through to the rotating cylinder (6) from wind wheel main shaft (16) center and to be connected with slide cartridge (7), rotate with wind wheel, knob pull bar (9), the thrust-bearing (8) bottom slide cartridge (7) is to pylon (20) bottom, because knob pull bar (9) does not rotate, just can be connected with the degree of tightness machine, during the wind wheel hypervelocity, degree of tightness mechanism loosens, and knob pull bar (9) moves upward, adjust steel cable (3) loosens thereupon, internal lobe (2) to the extrinsic deflection angle, drives siphonal lobe (1) by connecting rod (5) and inwardly rotates angle under centrifugal deflecting torque effect, and wind speed round descends; When wind speed round was on the low side, degree of tightness mechanism tightened up, and knob pull bar (9) moves downward, and adjusted steel cable (3) and tightened up thereupon, and internal lobe (2) and siphonal lobe (1) be return thereupon also, the wind speed round raising; The blade dotted line position is a wind wheel stall angle among Fig. 2, and solid line position is the running best angle.
