Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments.

For ordinary workers in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0047] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] When the photovoltaic power generation system is set up in a large span area such as a hillside, a fish pond, or a farm, the photovoltaic bracket 1 is generally used for arrangement. In the arrangement direction, a plurality of photovoltaic brackets 1 are connected with a load-bearing cable 2, and the photovoltaic panels are installed on the load-bearing cable 2. In actual application, due to the large span of the photovoltaic bracket 1, the length of the load-bearing cable 2 between two adjacent photovoltaic brackets 1 is relatively long. When encountering severe strong wind weather, the load-bearing cable 2 will swing under the action of the wind, which can easily cause the photovoltaic panel on the load-bearing cable 2 to swing greatly, and then easily cause damage to the photovoltaic module, increasing the maintenance cost of the photovoltaic power station.

[0049] In view of this, the utility model provides a photovoltaic power generation system to solve the problem that the photovoltaic panels on the supporting cables 2 are easily caused to swing greatly when encountering strong winds.

[0050] Combine the following Figures 1 to 4 , describing an embodiment of the utility model.

[0051] According to an embodiment of the present utility model, on one hand, a photovoltaic power generation system is provided, which includes a plurality of photovoltaic brackets 1, a load-bearing cable group, a shock-absorbing component 3 and a detection component 4.

[0052] Specifically, in an embodiment of the utility model, a plurality of photovoltaic brackets 1 are arranged at intervals along the arrangement direction, and the load-bearing cable group includes at least two load-bearing cables 2 arranged in the same direction. Along the arrangement direction, the load-bearing cable group sequentially connects all the photovoltaic brackets 1, and a photovoltaic panel is arranged on the load-bearing cable group. In other words, when it is necessary to arrange a photovoltaic power generation system between a first position and a second position, a plurality of photovoltaic brackets 1 are arranged between the first position and the second position, and are arranged at intervals between two adjacent photovoltaic brackets 1. Specifically to the actual application location, such as between two hillsides, the photovoltaic brackets 1 can be arranged at appropriate positions between the two hillsides, and then the photovoltaic brackets 1 between the two hillsides can be serially connected in sequence through the load-bearing cables 2. In order to stably install the photovoltaic panel, it is necessary to arrange two load-bearing cables 2 in the same direction, and then overlap the photovoltaic panel between the two load-bearing cables 2.

[0053] Furthermore, in an embodiment of the utility model, the shock absorbing assembly 3 is arranged on the ground of the arrangement area, for example, it can be the ground of a suitable area of ​​a hillside, the ground at the edge of a fish pond, or the ground around a farm. The shock absorbing assembly 3 is provided with a movable end, and the movable end is connected to the load-bearing cable 2 through a cable 5, and the movable end has a motion state of moving toward and away from the load-bearing cable 2. In actual application, when the movable end is away from the load-bearing cable 2, the cable 5 can be tightened, and correspondingly, the load-bearing cable 2 is also tightened, thereby reducing the swing of the load-bearing cable 2. When the movable end is close to the load-bearing cable 2, the cable 5 can be loosened, and correspondingly, the load-bearing cable 2 is also at the tension level during normal operation.

[0054] Further, in the embodiment of the utility model, the detection component 4 is arranged on the load-bearing cable 2, and the detection component 4 is used to detect the strain parameter of the load-bearing cable 2, and the detection component 4 is connected to the shock absorbing component 3. The strain parameter can be the stretching amount of the load-bearing cable 2 per unit time, or the twisting amount of the load-bearing cable 2 per unit time.

[0055] In practical applications, the detection component 4 can obtain the working state of the load-bearing cable 2 in real time according to the strain parameters of the load-bearing cable 2, such as the swing amplitude, the swing frequency, and the stretching length. The detection component 4 can adjust the position state of the active end of the shock-absorbing component 3 according to the working state of the load-bearing cable 2, thereby adjusting the tension of the cable 5 and the load-bearing cable 2 accordingly.

[0056] Furthermore, in an embodiment of the utility model, the shock absorbing assembly 3 and the detection assembly 4 are arranged in a matching manner, and multiple groups of the shock absorbing assembly 3 and the detection assembly 4 can be arranged correspondingly, and multiple groups of matching shock absorbing assemblies 3 and detection assemblies 4 can be arranged at different positions of the load-bearing cable 2, so as to adjust the tension degree of different positions of the load-bearing cable 2.

[0057] As for the number of the shock absorbing components 3 and the detection components 4, those skilled in the art can set them according to the actual situation. This embodiment does not limit this, as long as the corresponding technical effects can be achieved.

[0058] In this way, the utility model is provided with a shock-absorbing component 3 and a detection component 4. When the load-bearing cable 2 is strained by wind force, the detection component 4 can obtain the strain information of the load-bearing cable 2 in real time, thereby correspondingly adjusting the position of the movable end on the shock-absorbing component 3 to make the movable end close to or away from the load-bearing cable 2, and then automatically adjusting the tension of the cable 5, and correspondingly adjusting the tension of the load-bearing cable 2 to reduce the swing of the load-bearing cable 2. In other words, the detection component 4 can understand the swing amplitude of the load-bearing cable 2 according to the strain information of the load-bearing cable 2. When the swing amplitude of the load-bearing cable 2 is large, the movable end is adjusted to make the movable end away from the load-bearing cable 2, and the cable 5 is tightened, thereby reducing the swing of the load-bearing cable 2. When the swing amplitude of the load-bearing cable 2 is small, the movable end is adjusted to make the movable end close to the load-bearing cable 2, and the cable 5 is loosened to make the load-bearing cable 2 at a normal tension level. Therefore, the utility model can ensure that the strain of the load-bearing cable 2 is at a minimum level and protect the photovoltaic module to the greatest extent.

[0059] Further, in an optional embodiment, the detection assembly 4 includes a strain rib 41 and a detection device 42. Specifically, in the embodiment of the utility model, the strain rib 41 is arranged in the load-bearing cable 2 along the length direction of the load-bearing cable 2, and the strain rib 41 changes simultaneously with the load-bearing cable 2. That is, the strain rib 41 is directly twisted in the load-bearing cable 2 and becomes a part of the load-bearing cable 2, so that the strain rib 41 can change simultaneously with the load-bearing cable 2.

[0060] Furthermore, in the embodiment of the utility model, the detection device 42 is communicatively connected with the strain rib 41 and the shock absorbing assembly 3 , and the detection device 42 is used to obtain the strain parameters of the strain rib 41 .

[0061] Further, in an optional embodiment, the strain rib 41 is composed of a carbon fiber composite rib and a fiber Bragg grating sensor. The fiber Bragg grating sensor is embedded in the carbon fiber composite rib and arranged in the load-bearing cable 2 along the length direction of the load-bearing cable 2, and the fiber Bragg grating sensor is connected to the detection device 42 through a signal line.

[0062] Carbon fiber composite bars are widely used in civil engineering and structural reinforcement as a substitute or supplement to steel bars due to their high strength, high modulus, low density and corrosion resistance. Fiber Bragg Grating sensors can sense and record strain changes along the length of the optical fiber. When fiber Bragg Grating sensors are embedded in carbon fiber composite bars, strain bars 41 are formed, namely FBG (Fiber Bragg Grating)-CFRP (Carbon Fiber Reinforced Polymer) bars. This intelligent bar material can monitor its own strain state in real time when subjected to stress, thereby realizing structural health monitoring and performance evaluation. This is of great value for the safety monitoring and maintenance of large infrastructure such as bridges and buildings, and can provide early warning of potential structural damage or failure risks.

[0063] With such arrangement, the embodiment of the utility model can sensitively detect the stress-strain information of the load-bearing cable 2 under adverse weather conditions by forming the strain ribs 41 with carbon fiber composite ribs and fiber grating sensors, and transmit the information to the detection device 42, thereby instructing the shock-absorbing assembly 3 to work and automatically adjusting the tension of the cable 5, thereby automatically adjusting the tension of the load-bearing cable 2, thereby reducing the swing of the load-bearing cable 2 and protecting the safety of the photovoltaic assembly to the greatest extent.

[0064] Further, in an optional embodiment, the shock absorbing assembly 3 includes a cable clamp 31 and a shock absorber 32. Specifically, in the embodiment of the utility model, one end of the cable clamp 31 is fixed to the load-bearing cable 2, and the other end of the cable clamp 31 is connected to the first end of the cable 5.

[0065] Further, in an optional embodiment, the shock absorber 32 includes a base 321 and a driving cylinder 322. Specifically, in the embodiment of the utility model, the base 321 is arranged on the ground of the arrangement area, and the driving cylinder 322 is arranged on the base 321. The driving cylinder 322 is provided with a telescopic rod, the end of the telescopic rod is the active end, and the driving cylinder 322 is communicatively connected with the detection component 4. The detection component 4 can adjust the position state of the telescopic rod on the driving cylinder 322 according to the working state of the load-bearing cable 2, thereby correspondingly adjusting the tension of the cable 5 and the load-bearing cable 2.

[0066] Further, in an optional embodiment, the shock absorber 32 further includes a first cable head 323, which is rotatably disposed on the movable end, and the first cable head 323 is connected to the second end of the cable 5. The first cable head 323 and the movable end can be connected by a first pin shaft and a first pin hole 325, and the first cable head 323 and the movable end are both provided with a first pin hole 325. After the first pin shaft passes through the first pin hole 325, the first cable head 323 and the movable end are connected, so that the first cable head 323 is rotatably disposed on the movable end.

[0067] Furthermore, in an optional embodiment, the base 321 is a ball joint support, and a universal ball joint 324 suitable for moving in the ball joint support is provided at one end of the driving oil cylinder 322 close to the base 321. In this way, the embodiment of the utility model is provided with a ball joint support and a universal ball joint 324, and when the load-bearing cable 2 is affected by wind and swings, the cable 5 can also pull the base 321 to tilt in various directions, thereby improving the flexibility of the base 321 and preventing the base 321 from collapsing under the pulling of the load-bearing cable 2.

[0068] Further, in an optional embodiment, the cable clamp 31 includes a pair of clamps 311 and a fixing member 312. Specifically, in the embodiment of the utility model, each clamp 311 of the pair of clamps 311 is provided with a groove 3111, and the groove 3111 can be realized by forming an arc structure on the clamp 311. The two grooves 3111 are semicircular structures. After the pair of clamps 311 are aligned and installed, the semicircular structures of the two grooves 3111 are aligned to form a through groove suitable for the insertion of the load-bearing cable 2. The inner diameter of the through groove is less than or equal to the radius of the load-bearing cable 2. Further, the fixing member 312 fixes the pair of clamps 311 so that the two clamps 311 clamp the load-bearing cable 2 in the through groove. As for the fixing method of the fixing member 312, it can be fixed by a buckle slot, and the two clamps 311 can also be directly welded by welding. Of course, this embodiment is only an example of the fixing method of the fixing member 312, but it is not limited to this.
