It can not only solve or partially solve the power supply of the bridge itself (such as power supply for street lights, monitoring systems, etc.), but also supply power to the outside.

[0003] However, the solar photovoltaic panels placed on the upper end of the bridge in the prior art are relatively single and can only realize the reception and conversion of light energy. Summary of the Utility Model

[0014] The adjustable photovoltaic central stabilizer plate for suppressing bridge flutter and vortex-induced vibration in this solution can adjust the aerodynamic characteristics of the bridge and use clean energy to adjust the aerodynamic characteristics of the bridge, thereby achieving the effects of energy conservation and carbon reduction.

[0033] Referring to Figures 1 to 4 , a bridge flutter and vortex-induced vibration suppression adjustable photovoltaic central stabilizer plate, comprising a support column 100, a photovoltaic fixing bracket 200, a photovoltaic panel 210, an angle adjustment mechanism 300, and a wind speed measurement module 400.

[0034] The support column 100 is fixedly installed at the upper end of the bridge 001, and the support column 100 is vertically arranged.

[0035] Both ends of the photovoltaic fixing bracket 200 are respectively set as a hinged end and a driving connection end, and the hinged end is hingedly connected to the support column 100. The photovoltaic panel 210 is fixedly installed on the end face of the photovoltaic fixing bracket 200, and the photovoltaic fixing bracket 200 and the photovoltaic panel 210 together form the central stabilizer plate of the bridge to play the role of the central stabilizer plate.

[0036] The angle adjustment mechanism 300 is arranged between the photovoltaic fixing bracket 200 and the support column 100. Specifically, in this embodiment, the angle adjustment mechanism 300 is set as a linear driving device. In other embodiments, the angle adjustment mechanism 300 can also be set as a rotary driving device. Specifically, in this embodiment, the angle adjustment mechanism 300 is set as a hydraulic linear driving device. Naturally, the hydraulic linear driving device should be equipped with structures such as a hydraulic pump to realize the normal operation of the hydraulic linear driving device. In other embodiments, the angle adjustment mechanism 300 can also be set as an electric linear driving device, and those skilled in the art can select the angle adjustment mechanism 300 according to actual needs.

[0037] The lower end of the angle adjustment mechanism 300 is hinged to the support column 100, and the output end of the angle adjustment mechanism 300 is hinged to the driving connection end. When the angle adjustment mechanism 300 works, it drives the photovoltaic fixing bracket 200 to flip relative to the support column 100 so that the horizontal angle of the photovoltaic fixing bracket 200 changes.

[0038] The adjustable photovoltaic central stabilizing plate for suppressing bridge flutter and vortex-induced vibration further includes a speed measurement and installation structure 500. In this embodiment, the speed measurement and installation structure 500 is set as the central separator of the bridge. The speed measurement and installation structure 500 is fixedly installed at the upper end of the bridge 001 and is disposed beside the support column 100. Specifically, in this embodiment, the number of the speed measurement and installation structures 500 is set to two, and the two speed measurement and installation structures 500 are respectively disposed on the front and rear sides of the support column 100. By setting the number of the speed measurement and installation structures 500 to two and disposing the two speed measurement and installation structures 500 on the front and rear sides of the support column 100, it is possible to avoid setting the speed measurement and installation structure 500 on a single side of the support column 100, thereby preventing the asymmetry of the structures on the front and rear sides of the support column 100 from affecting the normal operation of the photovoltaic fixing bracket 200 and the photovoltaic panel 210.

[0039] The wind speed measurement module 400 can be fixedly installed at the upper end of one of the speed measurement and installation structures 500. The wind speed measurement module 400 is directly signal-connected to the angle adjustment mechanism 300 or is signal-connected to the angle adjustment mechanism 300 through a control module.

[0040] When the wind speed measurement module 400 detects that the wind speed has not reached the critical wind speed of bridge flutter and vortex-induced vibration, the angle adjustment mechanism 300 drives the photovoltaic fixing bracket 200 to flip to a horizontal position so that the photovoltaic panel 210 can receive sunlight in a larger range, thereby improving the power generation efficiency of the photovoltaic panel 210.

[0041] When the wind speed measurement module 400 detects that the wind speed has reached the critical wind speed of bridge flutter and vortex-induced vibration, the angle adjustment mechanism 300 drives the photovoltaic fixing bracket 200 to flip to a vertical or nearly vertical position, thereby suppressing the flutter and vortex-induced vibration of the bridge 001 and effectively suppressing the wind-induced vibration of the bridge 001.

[0042] In other embodiments, a sensor can also be disposed at the upper end of the speed measurement and installation structure 500 or other components to detect the angle of sunlight, and the sensor is signal-connected to the angle adjustment mechanism 300 so that the photovoltaic panel 210 remains perpendicular to the sunlight when the critical wind speed of bridge flutter and vortex-induced vibration is not reached, thereby improving the power generation efficiency of the photovoltaic panel 210. Those skilled in the art can choose whether to add a sensor to detect the angle of sunlight according to actual needs.

[0043] Specifically, in this embodiment, the stable structure of this bridge 001 further includes a power supply (the power supply is not shown in the figure). The wind speed measurement module 400, the angle adjustment mechanism 300, and the photovoltaic panel 210 are all electrically connected to the power supply. The photovoltaic panel 210 can receive the energy of sunlight and convert it into electrical energy to provide power for the power supply. The power supply stores electrical energy to provide power for the wind speed measurement module 400 and the angle adjustment mechanism 300, so that the wind speed measurement module 400 and the angle adjustment mechanism 300 can work normally to ensure that the adjustable photovoltaic central stabilizer plate for suppressing bridge flutter and vortex-induced vibration can work normally.

[0044] In other embodiments, the photovoltaic panel 210 of this solution can also be connected to an external power grid, and the wind speed measurement module and the angle adjustment mechanism 300 are powered through the external power grid. Those skilled in the art can select the power supply method of this solution according to actual needs.

[0045] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
