Technical field

The utility model relates to a kind of swing blade type high-efficiency wind driven generator.

Background technique

The traditional wind-driven generator absorption and the acting pattern of conversion wind energy and the design of mechanical structure all exist more critical problem; Such as traditional spoon formula wind-powered electricity generation machine is removed few part and is used for outside the blade of effectively acting; About all the other most of blades are in still upwind all be irregular instigating, inevitably understand rough air, not only can increase the vibration of fuselage; Bring destruction, also limited the utilization rate in installation density and soil fuselage.

Summary of the invention

The purpose of the utility model provides a kind of swing blade type high-efficiency wind driven generator, when utilizing this wind turbine power generation, can improve the conversion ratio of wind energy greatly, increases generating capacity.

The technical problem that the utility model will solve is through providing a kind of swing blade type high-efficiency wind driven generator with following structure to solve; It comprises with the central shaft being the support at center; At a plurality of swing type blades that support one side distributes, the position near blade on support is equipped with position-limited shaft, at the edge of support spacing damping spring is installed; Said support is fixing integral body; Be symmetrically distributed in the periphery of central shaft, with central shaft for being axially connected, blade pass is crossed the blade axis and is axially connected on support.

Support and central shaft are axially connected, and can be that rotate at the center with the central shaft, are equipped with one or a plurality of blades evenly are installed in a side of support; One side of blade is fixedly connected with the blade axis, and the blade axis is axially connected on support, when the number of every group of blade during greater than 1; The opposite side of blade can the axle property be equipped with synchronous coupling shaft; The synchronous coupling shaft of every group of blade is connected by synchronising (connecting) rod, and the length of synchronising (connecting) rod equates with the spacing of adjacent vanes axis, and all less than the length of blade; Side near blade on support is equipped with position-limited shaft, and the distance of the blade pass between centers that position-limited shaft is adjacent is less than the length of blade.

Spacing damping spring is fixedly connected on the edge of support, and a side of spacing damping spring and the bearing of trend of support have certain angle, thereby limits the pendulum angle of blade.

This swing blade type high-efficiency wind driven generator has been broken the mode of operation of traditional wind-powered electricity generation machine; It mainly is rotation angle and a direction of utilizing the cooperation control blade of blade axis, position-limited shaft and spacing damping spring; In the process that guarantees the wind-driven generator running; The blade that makes each accept wind-force goes to where all can be adjusted to the angle that helps absorbing and transforming wind energy automatically.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 shows the mode of execution of the utility model

Be set at the sense of rotation of blade clockwise in the mode of execution, wind blows from bottom to top.

Take one group of blade to illustrate, when support 2 was in the A point, blade 3 was axially connected on support 2 through blade axis 4; Position-limited shaft 7 is connected the side of support 2 near blade 3, and synchronising (connecting) rod 6 runs through one group of blade 3 through the synchronous coupling shaft 5 on blade 3 of being axially connected and is connected in one, and spacing damping spring 8 is fixedly connected on the edge of support 2; The part of spacing damping spring 8 is propped up from support 2, and with the elongation line of support 2 certain angle is arranged, and this moment, wind blew from bottom to top; Blade 3 is moving by wind, rotates near support 2, meanwhile through blade axis 4; Synchronising (connecting) rod 6 merges whole group blade 3 as a whole through the synchronous coupling shaft on the blade 35; Each blade 3 of 3 groups in blade all is synchronized with the movement relies on support 2, be close to the position-limited shaft 7 on the support 2 until blade 3, this moment, whole group blade 3 still had certain angle with wind direction; Can be along with blowing along the circle that with central shaft 1 is the center of circle of wind clockwise rotate, this moment, blade 3 was in the angle that helps absorbing and transforming wind energy.

Run to from the A point the process that B orders at support 2; There is not the variation of occurrence positions relation between whole group blade 3 and the support 2; This moment, blade 3 was along with blowing along the circle that with central shaft 1 is the center of circle of wind clockwise rotates; Blade is in the angle that helps absorbing and transforming wind energy, and the choke effect is more obvious.

Run to from the B point the process that C orders at support 2; There is not the variation of occurrence positions relation between whole group blade 3 and the support 2; This moment, blade 3 was along with blowing along the circle that with central shaft 1 is the center of circle of wind clockwise rotates; Blade is in the angle that helps absorbing and transforming wind energy, and the choke effect is the most obvious.

Run to from the C point the process that D orders at support 2; There is not the variation of occurrence positions relation between whole group blade 3 and the support 2; This moment, blade 3 was along with blowing along the circle that with central shaft 1 is the center of circle of wind clockwise rotates; Blade is in the angle that helps absorbing and transforming wind energy, and the choke effect has slightly and weakens.

Run to from the D point the process that E orders at support 2; Run to the angle of blade 3 when parallel with wind direction, the influence that blade 3 receives wind-force through 4 beginnings of blade axis toward rotating, meanwhile away from the direction of support 2; Synchronising (connecting) rod 6 merges whole group blade 3 as a whole through the synchronous coupling shaft on the blade 35; Each blade 3 of 3 groups in blade all is synchronized with the movement away from support 2, is close to 8 parts from support of spacing damping spring until blade 3, blade 3 receives the influence of wind-force and spacing damping spring 8; Still keeping certain angle with wind direction; Blade 3 is along with blowing along the circle that with central shaft 1 is the center of circle of wind clockwise rotates at this moment, and blade 3 is in the angle that helps absorbing and transforming wind energy, and the choke effect is comparatively obvious.
