It crosses cover board and limits 2 downlink of swinging frame swing extreme position at this, so that controlling swing does the swing of constant angle taper.
Its concrete operating principle integrated structure map analysis is as follows:
This secondary design is with four individual blades 1 instead of traditional wind wheel structure, and its sharf 3 is nibbled by gear
It closes transmission to be connected with servo motor 6, the angle of attack of blade 1 can be adjusted by servo motor 6 in this way, wind-force acts on four leaves
On piece 1, swinging frame 2 is driven to do cone during cooperating adjusting of the servo motor 6 to 1 angle of attack of blade, four blades 1 to swing
Pendulum motion.
With certain tilt angle when swinging frame 2 is installed, when blade 1 is by wind-force, swinging frame 2 is driven to do regular
Conical pendulum motion, the angle of attack of each blade 1 control servo motor 6 by controller 35 and adjust, and each blade 1 reaches highest order
When setting (1 height of blade detects the judgement of connecting rod uplink and downlink movement position by displacement sensor 34), servo motor 6 adjusts blade 1
Position with respect to ground in level, and blade 1 by extreme higher position to uncomfortable 1 angle of completeblade of extreme lower position servo motor 6, make blade
1 bears wind-force area during the decline reduces, and blade 1 declines.When blade 1 reaches extreme lower position, controller 35 passes through
Servo motor 6 adjust blade 1 rotate 60 degree, direction is counterclockwise, and by least significant end to most significant end during motor do not adjust
1 angle of blade makes blade 1 bear wind-force area and increases, and blade 1 rises.Similarly, each blade 1 repeatedly by least significant end to
Most significant end, the movement of most significant end to least significant end, while blade 1 are acted on the conical pendulum motion to form swinging frame 2 by wind-force.
Fig. 6 is that upper disk 8 and disk hook 9 and 10 drive mechanism figure of link mechanism, swinging frame 2 do conical pendulum motion
When, the upper disk 8 being connected with swinging frame 2 also does conical pendulum motion therewith, the four disks hook connecting with upper disk 8
9 are evenly distributed on the circumference of disk 8, and disk hook 9 is connected with link mechanism 10, and connecting rod blunt end and disk phase
It cuts, the conical pendulum motion of upper disk 8 just drives the successively regular up and down motion of link mechanisms 10 by disk hook 9, and four
Root connection rod set just successively presses connection rod set 1, connection rod set 2 102, connection rod set 3 103, the sequentially lower fortune of connection rod set 4 104
Dynamic, when connection rod set 1 moves down, connection rod set 2 102 can be with moving down after connection rod set 1, and connection rod set 3 103
It also can successively move down with connection rod set 4 104, it will be toward counter motion, in this way when connection rod set 1 moves to bottom
Connection rod set 1, connection rod set 2 102, connection rod set 3 103, connection rod set 4 104 also can be moved successively toward direction therewith, like this
Duplicate back and forth movement, its motion profile is such as sin cos functions track in simple terms.
As shown in fig. 7, for lower disc 12 and 10 connection structure diagram of link mechanism.Four connection rod sets being connect with upper disk 8,
Connection rod set is connected to form by upper connecting rod and lower link by rod connector 19 respectively, and the movement of upper disk 8 just passes through four connecting rods
Group passes to lower disc 12, and 13 top of central axis of lower disc 12 and 11 bottom of main shaft (namely 22 bottom of shell) are spherical pair
Connection, has a bolt hole on the circumference of end cap, is bolted and end cap is fixed on shell 22.
The central axis 13 for being illustrated in figure 8 lower disc 12 connects X-Y scheme, and four connection rod sets according to Fig. 6, Fig. 7 drive
Lower disc 12 moves, and central shaft 13 does taper swinging momvement along 11 line of main shaft, and spheroiding is designed to cooperate in the upper end of central axis 13
The taper swinging momvement of central axis 13, and the inner surface of positioning sleeve 25 and support sleeve 24 is also designed to curved surface, so that it may and lower disc
12 central axis 13 matches, and the lower end of support sleeve 24 is equipped with end cap 20, and end cap 20 is connected to outer further through threaded hole screw 23
On shell 22, so that 13 upper end of central axis of upper disk 8 can be fixed.And the spherical surface of connection rod set lower end and lower disc 12 are tangent,
Its tightness connecting with lower disc 12 can be adjusted by lock-screw 16, and disk is linked up with 9 lower end internal surface of hole and also set
Count into the screw thread cooperated with lock-screw 16.
13 lower end of central axis of lower disc 12 is connected with eccentric disc 14 by spherical pair, the taper swinging momvement of lower disc 12
It will drive central axis 13 and do circular cone swing, so eccentric disc 14 is driven to rotate.The rotation of eccentric disc 14 drives coupled power generation
Machine 15 generate electricity, as shown in Figure 10,13 lower end of central axis be also designed to it is spherical, with eccentric disc 14 and eccentric disc axle sleeve 27 match
Realize the rotation of eccentric disc 14, there is eccentric disc end cap 26 in the upper end of eccentric disc axle sleeve 27, is uniformly distributed on eccentric disc end cap 26
Six holes, can be with 28 tightening connection of screw on eccentric disc 14, the freedom degree that thus constrains central axis 13 to move up and down.
