Specific implementation

[0026] Below will combine the utility model embodiment's attached Figures 1-7 , the technical scheme in the utility model embodiment of the present utility model is described in detail. Embodiment 1

[0027] As Figures 1-7 shown, the utility model is a kind of cable clamp for the connection of flexible photovoltaic support horizontal support rod and prestressed steel strand, including support rod 5, steel strand 7 and cable clamp, cable clamp is connected on steel strand 5, the both ends of support rod 5 are connected with one cable clamp respectively, to form stable system, construction is convenient, installation is simple.

[0028] As Figures 1-3 shown, cable clamp includes link connecting block 1, fixed clamp block 2, movable clamp block 3 and locking piece 4, wherein link connecting block 1 is arranged in fixed clamp block 2, and link connecting block 1 and fixed clamp block 2 are integrally formed, connecting block 1, fixed clamp block 2, movable clamp block 3 are all used aluminum alloy material, texture is light, high strength, not only can improve the strength of cable clamp, but also can reduce cable clamp deadweight, to reduce additional load.

[0029] The link connecting block 1 in the embodiment is perpendicular to the upper surface of the fixed clamp block 2, the movable clamp block 3 is attached to the lower surface of the fixed clamp block 2, and the movable clamp block 3 and the fixed clamp block 2 are both recessed at the four corners and have upper and lower through holes. The through holes of the movable clamp block 3 and the fixed clamp block 2 are connected, and the through holes are used to pass through the locking piece 4 to tightly attach and lock the movable clamp block 3 and the fixed clamp block 2, and the whole is fixed on the steel strand.

[0030] As Figures 1-2 shown, through -hole 11 is arranged on link connecting block 1, and through -hole 11 is used to connect with support rod 5, to improve horizontal wind resistance performance and improve stability.

[0031] In this embodiment, the rod connecting block 1 is also provided with a through groove 12, which penetrates through both surfaces of the rod connecting block 1. By providing the through groove 12, the weight of the rod connecting block 1 can be further reduced, thereby further reducing the weight of the cable clamp and reducing the additional load.

[0032] In this embodiment, the fixed clamping block 2 and the movable clamping block 3 are fitted together, and a first clamping part 21 and a second clamping part 31 are respectively opened on their mating surfaces. The first clamping part 21 and the second clamping part 31 are grooves. The grooves are semi-circular in cross-section, and both ends of the grooves extend outward, penetrating the surfaces of the fixed clamping block 2 and the movable clamping block 3.

[0033] In this embodiment, the first clamping part 21 and the second clamping part 31 are symmetrical to each other. During the installation operation, the first clamping part 21 and the second clamping part 31 are respectively clamped onto the steel strand 7, and then joined together and fixed by the locking member 4, so as to fix the cable clamp on the steel strand 7.

[0034] Preferably, the first clamping part 21 and the second clamping part 31 are semi-circular grooves, which facilitate positioning and keep the steel strand in the groove so that it will not move between the fixed clamping block 2 and the movable clamping block 3, thus reducing the difficulty of installation. At the same time, the semi-circular shape increases the contact area with the steel strand 7, which can make the fixation more stable.

[0035] In this embodiment, the locking component 4 is a locking bolt and a matching locking nut. The locking bolt passes through the openings of the fixed clamping block 2 and the movable clamping block 3, and then is threadedly connected to the locking nut, so as to tightly fix the fixed clamping block 2 and the movable clamping block 3 together.

[0036] like Figure 4 and Figure 7 As shown, in actual installation, the steel strand 7, affected by gravity, will usually sag from the middle, thus forming a certain tilt angle. Of course, the tilt angle of the steel strand 7 will not be too large and needs to meet certain specifications. After the cable clamp is fixedly installed on the steel strand 7, the cable clamp remains perpendicular to the steel strand 7. Then, the member connecting block 1 of the cable clamp is tilted, forming a tilt angle β with the vertical direction. Through the tilt angle β, it can always be ensured that the member connecting block 1 is perpendicular to the horizontal plane.

[0037] Preferably, in this embodiment, the extension direction of the groove is the same as the inclination direction of the rod connecting block 1, and also the same as the through direction of the through hole 11. Therefore, all the rod connecting blocks 1 of the cable clamps are parallel to each other, which makes it easy for the two ends of the support rod 5 to be attached to and fixed with a rod connecting block 1 respectively.

[0038] If the rod connecting blocks 1 of the cable clamps are all kept completely consistent and have no inclination angle β, the rod connecting blocks 1 will not be parallel, and when the two cable clamps are connected by the struts 5, since it is necessary to be fixed tightly, the struts 5 need to be completely attached to the rod connecting blocks 1, at this time, the cable clamps will pull the steel strands 7, so that the angle of the steel strands 7 changes, which will affect the steel strands 7 themselves.

[0039] Preferably, the inclination angle β of the rod connecting block 1 ranges from 0° to 10°, and a suitable angle of the rod connecting block 1 can be selected according to the actual situation of the steel strand 7.

[0040] As shown in Figure 5 The two ends of the strut 5 are flat parts 51, which are used to attach to the rod connecting block 1, and the flat shape is convenient for attachment. The area where the flat part 51 is located is provided with a connecting hole 52, which is used to pass through the connecting piece 6 to fixedly connect the strut 5 and the rod connecting block 1, thereby realizing the fixed connection of the strut 5 and the cable clamp.

[0041] The connecting piece 6 in this embodiment is a connecting bolt and a connecting nut matched therewith. The connecting bolt passes through the connecting hole 52 of the strut 5 and the through hole 11 of the rod connecting block 1, and then is screwed with the connecting nut, thereby realizing the fixed connection of the strut 5 and the cable clamp.

[0042] Preferably, the length of the connecting bolt is provided in multiple specifications to connect different numbers of struts 5. Specifically, two through holes 11 are provided on the rod connecting block 1, and one or more struts 5 can be attached to the two sides of each through hole 11. In this way, the same cable clamp can connect multiple struts 5, and only the length of the connecting bolt needs to be sufficient to pass out and be screwed with the connecting nut for locking.

[0043] Preferably, when the number of struts 5 connected to the same through hole 11 is even, the struts 5 are preferably evenly distributed on the two sides of the through hole 11, and then fixed by the connecting piece 6, so that the stability of the fixed connection is higher.

[0044] The use method of the cable clamp for connecting the transverse strut of the flexible photovoltaic support and the prestressed steel strand in this embodiment is as follows:

[0045] Take a cable clamp, make fixed clamp block 2 and movable clamp block 3 clamp steel strand 7, and through locking piece 4 preliminarily fix fixed clamp block 2 and movable clamp block 3, make steel strand 7 be in the hoop tight part of fixed clamp block 2 and movable clamp block 3, then take another cable clamp, repeat operation, preliminarily fix the cable clamp 7 on another steel strand 7, and the rod connecting block 1 of two cable clamps are parallel to each other, then take a strut 5, make the flat part 51 of one end of the strut 5 and the rod connecting block 1 of the cable clamp adhere to each other, and be fixedly connected through connecting piece 6, then adjust another cable clamp, make its rod connecting block 1 and the other end flat part 51 of the strut 5 adhere to each other and be fixedly connected through connecting piece 6, finally through locking piece 4, lock and fix the two cable clamps on the corresponding steel strand 7 in turn, repeat the above operation subsequently, namely, the stable system can be formed.

[0046] The above examples only illustrate the technical idea of the present application, and cannot limit the protection scope of the present application. Any modification made on the basis of the technical scheme according to the technical idea of the present application falls within the protection scope of the present application.
