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.
