[0004] 2. Low efficiency in length adjustment: Traditional steel strand cables rely on manual adjustment, which is time-consuming and has poor accuracy.

[0005] 3. Insufficient anchoring reliability: Existing anchorages (such as wedge-type anchorages and threaded fork-ear type anchorages) are prone to loosening under high-frequency vibration.

[0006] 4. Traditional flexible photovoltaic support systems have a large number of foundations and piles, resulting in high costs and long construction periods.

[0007] 5. Traditional flexible photovoltaic support systems require tensioning of each load-bearing cable, resulting in low construction efficiency. Utility Model Content

[0008] The technical problem to be solved by this utility model is to address the above-mentioned shortcomings of the existing technology. The purpose of this utility model is to provide a photovoltaic cable net structure that can automatically extend.

[0009] The technical solution of this utility model is: a photovoltaic cable net structure that can automatically extend, including at least two spaced-apart side cables, and multiple spaced-apart load-bearing cables for installing photovoltaic modules between two adjacent side cables. Each side cable has an end post at both ends, one end post having an anchoring unit for anchoring the side cable, and the other end post having an adjustment mechanism for tensioning the side cable; it also includes a controller, a wind speed sensor for detecting the wind force on the side cables, and a cable force sensor on the side cables. The controller is electrically connected to the cable force sensor, the wind speed sensor, and the adjustment mechanism.

[0010] As a further improvement, the adjustment mechanism includes an adjustment screw, one end of which is connected to the side cable, and the other end passes through the anchor seat of the end post and is provided with an adjustment nut. The adjustment mechanism also includes a drive unit for driving the adjustment nut to rotate.

[0019] Beneficial effects

[0020] Compared with the prior art, the advantages of this utility model are as follows:

[0022] 2. The cable net structure with the load-bearing cable and the side cable anchored together reduces the number of anchor piles and end column foundations.

[0023] 3. Automatic lengthening mechanism: The motor drives the nut and pull rod to achieve high-precision dynamic adjustment, breaking through the limitations of traditional manual adjustment.

Detailed Implementation

[0036] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0037] See Figures 1-9 A photovoltaic cable net structure capable of automatic extension includes at least two spaced-apart side cables 1, with multiple spaced-apart load-bearing cables 3 for installing photovoltaic modules 2 between adjacent side cables 1. Each side cable 1 has an end post 4 at both ends, one end post 4 having an anchoring unit 5 for anchoring the side cable 1, the anchoring unit 5 using existing anchoring devices, and the other end post 4 having an adjustment mechanism 6 for tensioning the side cable 1. The structure also includes a controller, a wind speed sensor 7 for detecting the wind force on the side cable 1, the wind speed sensor 7 being mounted on the side cable 1, and a cable force sensor 8 on the side cable 1. The controller is electrically connected to the cable force sensor 8, the wind speed sensor 7, and the adjustment mechanism 6.

[0038] The tension and wind force of the side cable 1 are detected by the cable force sensor 8 and the wind speed sensor 7. The adjustment mechanism 6 is controlled according to the tension and wind force to realize the automatic real-time adjustment of the cable force of the photovoltaic cable to adapt to different wind force effects and cable force loss compensation.

[0039] The adjustment mechanism 6 includes an adjustment screw 9, one end of which is connected to the side cable 1, and the other end passes through the anchor seat 10 of the end post 4 and is provided with an adjustment nut 11. The adjustment screw 9 is threadedly connected to the adjustment nut 11, and the adjustment nut 11 is rotatably connected to the anchor seat 10 through an end face bearing. The adjustment mechanism 6 also includes a drive unit 12 for driving the adjustment nut 11 to rotate.

[0040] The drive unit 12 is an electric motor or a hydraulic motor. The drive unit 12 drives the adjusting nut 11 to rotate through the gear transmission mechanism 13, the worm gear transmission mechanism 14, or the chain transmission mechanism 15.

[0041] like Figure 4 As shown, the gear transmission mechanism 13 includes a driving gear 23 connected to the drive unit 12 and a driven gear 24 connected to the adjusting nut 11, with the driving gear 23 meshing with the driven gear 24.

[0042] like Figure 5 As shown, the gear transmission mechanism 13 includes a worm 25 connected to the drive unit 12 and a worm wheel 26 connected to the adjusting nut 11, with the worm 25 meshing with the worm wheel 26.

[0043] like Figure 6 As shown, the gear transmission mechanism 13 includes a drive sprocket 27 connected to the drive unit 12, a driven sprocket 28 connected to the adjusting nut 11, and a chain 29 connected to the drive sprocket 27 and the driven sprocket 28.

[0044] Preferably, the motor is a servo motor or a stepper motor, which is convenient for control.

[0045] The tension sensor 8 can be any one of a magnetic flux sensor, a tension sensor, or a built-in fiber Bragg grating. The wind speed sensor 7 can be a three-cup wind speed sensor or an ultrasonic wind speed sensor.

[0046] Furthermore, such as Figure 7 As shown, an anchor pile 16 is provided on one side of the end column 4. The anchor pile 16 is connected to the upper end of the end column 4 through a tie rod 17, which can improve the stability of the end column 4 during operation. The anchor pile and the end column are equipped with pre-embedded connectors, which transmit the force to the foundation through the anchor pile and the end column.

[0047] like Figure 8 , Figure 9As shown, both ends of the load-bearing cable 3 are connected to the side cable 1 via cable clamps 18, forming a cable net structure that transfers the force of the photovoltaic modules to the foundation. The cable clamps 18 are equipped with ear plates 19, and the load-bearing cable 3 is rotatably connected to the ear plates 19 via fork ears 20 and pins 21. Both ends of the load-bearing cable 3 are equipped with compression sleeves 22, which are threadedly connected to the fork ears 20 for easy adjustment. By tensioning the side cable, the arc length of the side cable decreases, causing the load-bearing cable to bear the force. Only the side cable needs to be tensioned for the load-bearing cable to passively bear the force, improving construction efficiency.

[0048] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these will not affect the implementation effect of this utility model or the practicality of the patent.
