When the photovoltaic support is used, the support frame is arranged at a proper position, and the prestressed rope connected with the support frame is arranged, so that the photovoltaic support can adapt to places such as undulating mountainous regions, lakes, fish ponds and the like where conventional rigid photovoltaic supports are not convenient to arrange.
The existing flexible photovoltaic support takes a prestressed cable as a bearing member, and the span is improved compared with a rigid photovoltaic support. In order to ensure a sufficiently large span between the two side supports, a sufficiently large tensile force needs to be applied to the rope in the initial state.
At present, the flexible photovoltaic support is fixed to the cable force that the rope was applyed, namely the tensile force of rope, and after the construction was accomplished promptly, the tensile force of rope can't be adjusted according to external environment. Under the strong wind weather, unable increase tension increases the stability of subassembly, and the subassembly produces easily and rocks, and then causes the solar cell panel in the subassembly to take place hidden crack, breakage. When the snow cover is subjected to heavy snow weather, the tensile force cannot be reduced, and before accumulated snow on the surface of the assembly is not cleared in time, the accumulated snow increases the internal stress of the rope and even exceeds the allowable stress, so that the rope is broken. And along with the use of support, can cause its lax after the bearing rope is tired, also can't adjust the tension of rope, can't guarantee that there is sufficient headroom below the subassembly.

When along with support 5's use, can cause its lax after 11 tireds of bearing rope, also need to rotate threaded rod 4 to first direction, adjust the distance of first traction block 2 and second traction block 3, make first traction block 2 keep away from second traction block 3, increase tension prevents that rope 11 from the tenesmus, guarantees that the subassembly below has sufficient headroom. In this embodiment, the first direction and the second direction are both directions in which the threaded rod 4 is rotated, and the setting of the first direction and the second direction may be determined according to the turning direction of the thread on the threaded rod 4. Rotation of the threaded rod 4 in a direction away from the second traction block 3 causes the first traction block 2 to move away from the second traction block 3, this direction being the first direction and vice versa.

Example two
The embodiment provides a cable force adjusting method of a flexible photovoltaic support, and based on the cable force adjusting device 1 of the flexible photovoltaic support in the first embodiment, the method includes the following steps: setting a normal range of the tension of the rope 11, and acquiring tension information of the rope 11 in real time; judging whether the tension of the rope 11 exceeds a normal range; if the tensile force of the rope 11 exceeds the normal range, wherein when the tensile force of the rope 11 exceeds the upper limit of the normal range, the driving device is started, the driving input end moves to drive the output end to be far away from the support frame, so that the end, connected with the output end, of the rope 11 is driven to move away from the support frame in the direction far away from the support frame, and the driving device is stopped until the tensile force of the rope 11 enters the normal range; when 11 stretching forces of rope surpass normal range lower limit, start drive arrangement, thereby the drive input removes and to drive the output and be close to the support frame and thereby drive 11 one end that is used for being connected with the output and be close to the support frame and remove to the direction of keeping away from the support frame, and until 11 stretching forces of rope get into normal range, stop drive arrangement. Therefore, when in use, the method can realize the function of adjusting the tension force of the rope 11 in the flexible photovoltaic bracket.
In this embodiment, the normal range is a range in which the tension of the rope 11 in the flexible photovoltaic support is allowed to vary, and as for the normal range of the tension of the rope 11, an upper limit and a lower limit of the tension can be set according to practical requirements, the upper limit is mainly related to the diameter and the material of the rope 11, in this embodiment, a steel strand of 15.2mm is preferably taken as an example, and the upper limit of the rope force is 130kN. The lower limit value is mainly related to span and sag, and the calculation formula is as follows.
Wherein m is the mass of rope 11 and photovoltaic board unit length, and l is the span, and d is the sag, and H is rope 11 tension. Therefore, the lower limit value can be set according to actual conditions.

For a mean value of the tension of the rope 11 of 3 minutes, the logic function is able to judge whether it is out of the normal range from the mean value. If the average tension of the rope 11 is larger than the normal range, the control motor 7 drives the threaded rod 4 to rotate, the first traction block 2 is made to be close to the second traction block 3, the rope 11 is loosened until the tension of the rope 11 returns to the normal range, and monitoring is continued. If the average tension of the rope 11 is smaller than the normal range, the control motor 7 drives the threaded rod 4 to rotate in the opposite direction, so that the first traction block 2 is far away from the second traction block 3, the rope 11 is tensioned until the tension of the rope 11 returns to the normal range, and monitoring is continued.
Through the device and the scheme, after the construction of the photovoltaic support 5 is completed, the tension of the rope 11 can be adjusted according to the actual situation on site. Thereby taut bearing rope 11 slows down the shake degree of subassembly under the strong wind weather, and loosens bearing rope 11 thereby makes it can bear bigger weight load when heavy snow weather, improves flexible photovoltaic support's adaptability.
