Description

Technical Field

[0001] The utility model relates to the field of cable bridges, in particular to a device for preventing a low-voltage cable bridge of a fan from settling and deforming. Background Art

[0002] In the construction of wind power, the low-voltage cable outlet of the wind turbine of the newly built wind power project is generally buried. The cable passes through the buried pipe, one end is connected to the tower, and the other end is connected to the corresponding equipment. In the buried structure, the cable needs to run underground, the installation remains unchanged, and the cost is relatively high. In order to save costs, many traditional forms of burying pipes from the bottom of the foundation are changed to the form of leading the cable from the bottom of the tower door through the cable bridge to the ground and then directly buried to the low-voltage side of the box transformer. This method has the following advantages: first, the box transformer can be set on the foundation of the wind turbine, saving land acquisition area; second, it can save a lot of cables, thereby reducing costs.

[0003] However, when using a bridge for cable routing, it is inconvenient to reserve a foundation for the cable bridge bracket directly on the wind turbine foundation (there will be a deviation between the reservation in advance and the subsequent positioning of the tower door direction), so the design usually considers setting the foundation directly on the backfill soil. Long-term use may cause settlement risks, which will cause the bridge to sink and the cables to be compressed, posing quality and safety risks. In addition, the bridge is not convenient to disassemble after installation, which is not conducive to the subsequent disassembly work and is not convenient to operate. Utility Model Content
