Double sag structure energy operative constraint flexible cable framves, prevent photovoltaic panel 25 from significantly being shaken by extreme crosswind under strong wind weather It is dynamic to turn on one's side.

When flexible cable frame needs repairing, the capel of arranged on left and right sides and lock hook are departed from.

Photovoltaic panel 25 or photo-thermal pipe smooth surface East and West direction rotation mode are：

By taking the flexible cable turning unit in southern side as an example：

As shown in Fig. 1,4, motor 26 drives the rotate counterclockwise of fixed pulley 8.3 to drive rectangular flexible rope frame 9 to rotate counterclockwise, So as to drive hexagon rigid frame 10 to rotate run-off the straight, the vertical edge position rise in its east side, the vertical edge position in west side Reduce；The position rise of the sag rope 17, horizontal load rope 19, anti-sag rope 21, dropper 23 in corresponding east side, the sag in west side Rope 18, horizontal load rope 20, anti-sag rope 22, the position of dropper 24 reduce, and drive the smooth surface court of photovoltaic panel 25 or photo-thermal pipe To rotating from east to west.

The second connecting strand 13.2 in the rope connection mechanism of south and north flanks can slide on corresponding traction fixed pulley 16, institute With when in photovoltaic panel 25 or photo-thermal pipe East and West direction rotary course, the upper-lower height of hexagon rigid frame 10 and East and West direction position are sent out During changing, the second connecting strand 13.2 can change therewith in the length of two sections of flexible cables of corresponding traction fixed pulley 16 both sides Become, compensate adjustment.

The regulative mode at photovoltaic panel 25 or the photo-thermal pipe elevation angle is：

When the straight line lifting movement driving device 11.1,11.2 on southern side hexagon rigid frame 10 moves downward, north The synchronous motion upwards of straight line lifting movement driving device 11.3,11.4 on side hexagon rigid frame 10.1, drives two water Flat load rope 19,20 moves to north side carrier direction, so as to drive photovoltaic panel 25 or the lower end of photo-thermal pipe to be rotated up, photovoltaic The elevation angle of plate 25 or photo-thermal pipe reduces.

Similarly, when the straight line lifting movement driving device 11.1,11.2 in southern side hexagonal-shaped frame 10 moves upwards, north Straight line lifting movement driving device 11.3,11.4 in side hexagonal-shaped frame 10.1 synchronously moves downward, and drives two horizontal loads Lotus rope 19,20 moves to southern side carrier direction, so as to drive photovoltaic panel 25 or the lower end of photo-thermal pipe to rotate down, photovoltaic panel 25 Or the elevation angle increase of photo-thermal pipe.

As shown in figure 5, in forward and backward load 6,7 columns（East, west load column）Rectangular flexible rope frame 9 on, positioned at upper horizontal stroke Multiple hexagon rigid frames 27 can also be set between rope and lower horizontal rope, with forming array formula flexible cable turning unit；So Array-type flexible rope frame is may be constructed, i.e.,：Flexible cable is respectively provided between two hexagon rigid frames 27 corresponding to south, north side Frame.Therefore, a flexible cable turning unit can drive the photovoltaic panel or photo-thermal pipe progress East and West direction on multiple flexible cable framves simultaneously Rotate.Than in the case of being used alone, the pulley quantity used in average each flexible cable frame is less in the case of array application.

, it is necessary to explanation, term "front", "rear", "left", "right", " vertical ", " water in description of the present utility model It is flat ", " longitudinal direction ", " transverse direction ", the orientation of the instruction such as " East, West, South, North " or position relationship be to be based on orientation shown in the drawings or position Relation is put, description the utility model is for only for ease of and simplifies description, rather than indicate or imply signified device or element There must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
