Description

Technical Field

[0001] This utility model belongs to the field of integrated application technology of photovoltaic power generation and sound-absorbing barriers, and specifically relates to an integrated photovoltaic sound-absorbing product suitable for rail transit. Background Technology

[0002] Currently, photovoltaic (PV) sound barrier technology is mainly used in highways and urban roads, typically installed on the sides of vertical sound barriers. The PV modules and sound-absorbing panels are inserted into the H-beams. However, the conversion efficiency of the PV modules is reduced due to the shading effect of the H-beams. Furthermore, the inconsistent spacing of the H-beams on existing lines makes it difficult to standardize the specifications of the PV modules inserted into the H-beams, hindering standardized production and resulting in high costs and low returns for PV sound barriers. The structural dynamic characteristics of steel wheels and rails in rail transit differ significantly from those of highways and urban roads. Existing technologies lack relevant examples for PV sound barrier systems in the rail transit field, particularly those that can replace sound-absorbing panels. The connection methods of the PV modules are insufficient to meet the reliability requirements under the vibration conditions of rail transit trains and also affect the ease of maintenance and use in the future.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content
