So, under the common regulation of first regulating part 14 and second regulating part 15, can improve the structural strength of two rope bodies 11 in the use greatly to can improve the structural rigidity of whole photovoltaic support 100, make it be suitable for (can reach more than 35 meters) in the scope of bigger span, can reach the photovoltaic support 100 and carry out on-the-spot quick construction installation and the purpose of use in complicated scenes such as mountain region, desert, improved photovoltaic system's overall rigidity and economic and practical performance greatly.
In this embodiment, a locking member 210 may be preferably installed at four corners of each photovoltaic module 200, and the locking member 210 is used to lock the corners of the photovoltaic modules 200 to the two rope bodies 11. Preferably, referring to fig. 6 and 10, the locking member 210 may include a receiving portion 211 bent into an L shape from a steel plate and a fixing portion 212, and the fixing portion 212 may be fixed to the rope body 11 by, for example, a clip or the like, so that the receiving portion 211 can be located above the rope body 11 for docking the photovoltaic module 200. The photovoltaic module 200 may be fastened to the receiving portion 211 by rivets or screws to assemble the photovoltaic module 200 and the two rope bodies 11.

As a preferred embodiment of the present embodiment, referring to fig. 1 to 3, each rope body 11 may include a main rope 111 and two inclined ropes 112 separately provided at opposite ends of the main rope 111, the main rope 111 being located between adjacent two support members 2, the inclined ropes 112 being connected to the load-bearing base surface by the first regulating members 14. The two inclined cables 112 are respectively used for abutting against the first adjusting pieces 14 arranged at two ends of the supporting member 2, so as to fix the main cable 111 on the supporting member 2. Of course, in the present embodiment, the two inclined cables 112 and the main cable 111 may be integrally configured, that is, two side portions of the rope body 11 form the inclined cable 112 under the abutting action of the side edges of the supporting member 2. Or the two inclined ropes 112 and the main rope 111 can be in split type splicing structures, which are all within the protection scope of the patent.

Or referring to fig. 3 and 5, it is also within the scope of the present patent for the first and second cables 12, 13 to be located between each adjacent two sets of rope members 1. That is, the first cable 12 and the second cable 13 should be inclined to form a traction force to the two main cables 111, and as for the first cable 12 and the second cable 13 to be inclined toward the inner side or the outer side of the two main cables 111, the embodiment is not particularly limited.
Of course, in this embodiment, referring to fig. 3 and 5, in order to effectively prevent the two main cables 111 of the same group from being changed in the interval due to the tensioning action of the first cable 12 and the second cable 13, a plurality of stay bars 17 may be preferably disposed between the two main cables 111 to connect the two main cables 111, and preferably, the length of the stay bar 17 and the interval between the two main cables 111 are equal, and this embodiment may not limit the specific installation form of the stay bars 17. In this embodiment, since the first cable 12 and the second cable 13 are obliquely stretched, the stay 17 may be preferably disposed at positions corresponding to the first cable 12 and the second cable 13, and thus, under the action of the stay 17, the lateral tension of the first cable 12 and the second cable 13 on the main cables 111 may be directly counteracted, so that the first cable 12 and the second cable 13 only have downward tension, and thus, pre-tightening or pre-loosening of the two main cables 111 may be achieved.
It should be noted that the above embodiments can be freely combined as needed. The foregoing is merely a preferred embodiment of the present application and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present application, which are intended to be comprehended within the scope of the present application.
