Mounted in the center on 11 top of fixed plate and the perforation 1a alignment of fixed plate 11, two guide wheels 5 are arranged in East and West direction, guide wheel 5
Shaft it is parallel with girder 202a；Sectional wheel 4 is fixed on girder 202a, and by the minimum point A1 of sectional wheel 4 and as spiral shell
Revolve the center line alignment of spring 2；Head end 31 as the wirerope of flexible piece 3 is fixed in movable plate 12 with eyelet bolt
Between, the end 32 of the wirerope as flexible piece 3 passes through the crack of fixed plate 11 and two guide wheels 5 from the centre of helical spring 2,
It is then passed through the duct 4a of the minimum point A1 of sectional wheel 4, then wirerope is fixed on sectional wheel 4 with wirerope briquetting 6.Solid
When determining wirerope, appropriate preload screw spring 2, so that the wirerope as flexible piece 3 in initial equilibrium conditions, is in exceptionally straight
State.
When girder 202a tracks rotation since initial equilibrium conditions, the wirerope as flexible piece 3 will be by gradually
In the race 42 for entering sectional wheel 4, at this point, movable plate 12 has been pulled upwardly, helical spring 2 is compressed, meanwhile, sectional wheel 4 is just
It will receive the tangential pulling force as the wirerope of flexible piece 3 and generate torsional moment.Girder 202a corner is bigger, as flexible piece
3 wirerope is also bigger around the length for entering sectional wheel 4, and helical spring 2 is also just compressed more severe, what sectional wheel 4 was subject to
Torsional moment is also bigger.On the other hand, the genetic analysis generated from eccentric torque, when the rotor of photovoltaic tracking bracket 20
202 be in 0 ° of initial equilibrium conditions when, the section center of gravity and rotation centerline O of rotor 202 are on same vertical line, this
When there is no eccentric moment generation, when girder 202a since 0 ° to any one of thing direction rotate when, the section of rotor 202
Center of gravity vertical line and rotation centerline will generate deviation, at this point, the effect in gravity will generate eccentric torque.With girder
The corner of 202a becomes larger, and the section center of gravity of rotor 202 also becomes larger relative to the deviation distance of rotation centerline, by
This eccentric moment generated is also just increasing.And the increase tendency of this eccentric torque is generated with eccentricity compensation device 10 just
Counter balance torque increase tendency coincide.Therefore, the two can cancel out each other, to achieve the purpose that eccentricity compensation.
The characteristics of eccentricity compensation device 10 is to compensate the variation tendency of torque to match with the variation tendency of eccentric torque,
Energy effective compensation eccentric torque is negatively affected to caused by photovoltaic tracking bracket 20, and structure is simple, easy for installation, reliability
It is high.
