The connection mode of the cable connection mechanism between the right bearing frame and the left flexible cable rotating unit is the same as the connection mode of the cable connection mechanism between the left bearing frame and the right flexible cable rotating unit, and is omitted here.
A flexible cable rack is arranged between the two flexible cable rotating units, and consists of two arc-shaped vertical cables 17 and 18, two horizontal load cables 19 and 20 and two anti-arc-shaped vertical cables 21 and 22, wherein the arc-shaped vertical cables 17 and 18, the horizontal load cables 19 and 20 and the anti-arc-shaped vertical cables 21 and 22 can be selected as steel strands, steel ropes, steel cables, steel ropes or steel chains; two ends of the two arc vertical ropes 17 and 18 are respectively and fixedly connected with two ends of the top edge of the rectangular frame of the hexagonal rigid frames 10 and 10.1 on the corresponding rectangular flexible rope frame 9 and the rectangular flexible rope frame 9.1, and two ends of the two horizontal load ropes 19 and 20 are respectively and fixedly connected with the corresponding linear lifting motion driving devices 11.1, 11.2, 11.3 and 11.4; two ends of the two anti-arc vertical ropes 21 and 22 are respectively connected with the rectangular frame bottom edges of the hexagonal rigid frames 10 and 10.1 on the corresponding rectangular flexible rope frame 9 and the rectangular flexible rope frame 9.1; the two pendant cords 17, 18 are provided with a plurality of hanger strings 23, 24 at intervals in the longitudinal direction with the corresponding anti-pendant cords 21, 22 below.

The double-sag structure can effectively restrain the flexible cable frame and prevent the photovoltaic panel 25 from being greatly rocked by strong crosswind to turn on one's side in strong wind weather.
When the flexible cable frame needs to be maintained, the chicken heart rings on the left side and the right side are separated from the latch hooks.
The east-west rotation mode of the light receiving surface of the photovoltaic panel 25 or the photo-thermal tube is as follows:
take a south-side flex cable rotation unit as an example:
as shown in fig. 1 and 4, the motor 26 drives the fixed pulley 8.3 to rotate anticlockwise to drive the rectangular flexible cable frame 9 to rotate anticlockwise, so as to drive the hexagonal rigid frame 10 to rotate and incline, the vertical edge of the east side of the hexagonal rigid frame is raised, and the vertical edge of the west side of the hexagonal rigid frame is lowered; the positions of the corresponding eastern arc hanging rope 17, the horizontal load rope 19, the anti-arc hanging rope 21 and the hanging wire 23 are raised, and the positions of the western arc hanging rope 18, the horizontal load rope 20, the anti-arc hanging rope 22 and the hanging wire 24 are lowered, so that the light receiving surface of the photovoltaic panel 25 or the photo-thermal tube is driven to rotate from east to west.
The second connecting ropes 13.2 in the rope connection mechanisms on the north and south sides can slide on the corresponding traction fixed pulleys 16, so that when the upper and lower heights and the east-west positions of the hexagonal rigid frame 10 are changed in the east-west rotation process of the photovoltaic panel 25 or the photo-thermal tube, the lengths of the two sections of flexible ropes on the two sides of the corresponding traction fixed pulleys 16 of the second connecting ropes 13.2 can be changed accordingly to carry out compensation adjustment.
The elevation angle of the photovoltaic panel 25 or the photo-thermal tube is adjusted in the following manner:
when the linear lifting driving devices 11.1 and 11.2 on the south side hexagonal rigid frame 10 move downwards, the linear lifting driving devices 11.3 and 11.4 on the north side hexagonal rigid frame 10.1 synchronously move upwards to drive the two horizontal load cables 19 and 20 to move towards the north side bearing frame, so that the lower end of the photovoltaic panel 25 or the photo-thermal tube is driven to rotate upwards, and the elevation angle of the photovoltaic panel 25 or the photo-thermal tube is reduced.
In the same way, when the linear lifting motion driving devices 11.1 and 11.2 on the south side hexagonal frame 10 move upwards, the linear lifting motion driving devices 11.3 and 11.4 on the north side hexagonal frame 10.1 synchronously move downwards to drive the two horizontal load cables 19 and 20 to move towards the south side bearing frame, so that the lower end of the photovoltaic panel 25 or the photo-thermal tube is driven to rotate downwards, and the elevation angle of the photovoltaic panel 25 or the photo-thermal tube is increased.
As shown in fig. 5, on the rectangular flexible cable frames 9 of the front and rear load 6, 7 upright posts (east and west load upright posts), a plurality of hexagonal rigid frames 27 may be disposed between the upper and lower transverse cables to form an array flexible cable rotating unit; the array type flexible cable frame can be formed by the following steps: flexible cable frames are provided between two hexagonal rigid frames 27 corresponding to the north and south sides. Therefore, one flexible cable rotating unit can drive the photovoltaic panels or the photo-thermal pipes on the flexible cable frames to rotate east and west. The number of pulleys per flexible cable is on average less in the case of an array application than in the case of an individual application.
In the description of the present invention, it should be noted that the terms "front", "rear", "left", "right", "vertical", "horizontal", "longitudinal", "transverse", "east, west, south, north", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the apparatus or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.
