[0031] Furthermore, the thin-film photovoltaic cell layer 52 in the solar guardrail module 5 absorbs and converts electrical energy and stores it in the supercapacitor module 54, and the high-strength tempered glass translucent protective cover 53 provides protection. At the same time, the additional fixing frame 56 and the buffer spring frames 562 on both sides thereof provide buffering to prevent damage to the solar guardrail module 5; at the same time, the piezoelectric energy recovery module 69 in the telescopic gap module 6 converts the vibration energy caused by the passage of vehicles into electrical energy for storage; when the temperature changes and the thermal expansion and contraction occurs, the lateral telescopic mechanism 64, the first shape memory alloy SMA spring 65 and the second shape memory alloy SMA spring 66 perform lateral buffering, and when the up and down changes or the vibration amplitude is large, the pressure sensor 690 at the bottom of the piezoelectric energy recovery module 69 is pressurized to control the relatively lower electric controller 692 to start, and the longitudinal electric-controlled hydraulic damper 693 starts to operate and begins to lift the relatively lower bottom plate frame layer 62 upward to keep it in a balanced state.

[0032] Working principle: In the factory, operators cut and blank materials according to the design and weld them to form standard prefabricated steel box girder 1 segments. They lay integrated temperature control layers 4 in designated areas on both sides of the prefabricated steel box girder 1, pre-embed a distributed temperature sensor network 43, and install a micro-fan heat dissipation module 8 in the inner cavity beam 11.

[0033] Then, the solar guardrail module 5 is layered and assembled with a high-strength tempered glass transparent protective cover 53, a thin-film photovoltaic cell layer 52, a base layer 51 and corresponding circuits, and the supercapacitor module 54 and the integrated intelligent charge and discharge controller 55 are installed on the lower part of the positioning plate 531.

[0034] Then, on-site assembly is carried out, the pillars 2 are erected, and each section of the prefabricated steel box girder 1 is accurately lifted into place and fixed using a crane. Then, the guardrail frame 3 is fixed to the upper part of the prefabricated steel box girder 1. Then, the solar guardrail module 5 is installed through the socket 31, and the bottom of the solar guardrail module 5 is installed on the prefabricated steel box girder 1 through the fixed structure. Then, the fixing frame 56 is installed, and the electrical lines are connected to the solar guardrail modules 5 along both sides of the prefabricated steel box girder 1, and all distributed temperature sensor networks 43 are connected to the integrated intelligent charge and discharge controller 55.

[0035] Then the telescopic gap module 6 is installed between the two prefabricated steel box girders 1, and the first fixed plate 695 on the outside of a top plate frame layer 61 inside it is fixedly connected to the top plate frame layer 61 through a first fixed bolt 696, and the other end of the first fixed plate 695 is connected to the fixed connection positioning plate 691 at the bottom of another top plate frame layer 61 through the first fixed bolt 696.

[0036] Finally, a sealing layer 7 is added to the outside of the telescopic gap module 6 to seal the telescopic gap module 6 and prevent external dust from entering.

[0037] When in use, the thin-film photovoltaic panel layer 52 in the solar guardrail module 5 absorbs and converts electrical energy and stores it in the supercapacitor module 54, and the high-strength tempered glass transparent protective cover 53 provides protection. At the same time, the additional fixing frame 56 and the buffer spring frames 562 on both sides thereof provide buffering to prevent damage to the solar guardrail module 5.

[0038] At the same time, the piezoelectric energy recovery module 69 in the telescopic gap module 6 converts the vibration energy caused by the vehicle passing into electrical energy for storage.

[0039] When the temperature changes and the device expands and contracts, the lateral telescopic mechanism 64, the first shape memory alloy SMA spring 65 and the second shape memory alloy SMA spring 66 perform lateral buffering. When the up and down changes or the vibration amplitude is large, the pressure sensor 690 at the bottom of the piezoelectric energy recovery module 69 is pressurized to control the relatively lower electric controller 692 to start, and the longitudinal electric hydraulic damper 693 starts to operate and begins to lift the relatively lower bottom plate frame layer 62 upward to keep it in a balanced state.
