Description

Wind farm underground cable laying guiding device Technical Field The utility model relates to the technical field of wind power generation, in particular to a wind power plant underground cable laying guiding device. Background A wind farm, also called a wind farm or a wind farm, is a facility for converting wind energy into electrical energy using wind power generators, typically consisting of a plurality of wind power generators, which are installed at specific locations in order to capture the wind energy to a maximum extent, and cables for wind farms are mainly used to transmit the electrical energy generated by the wind power generators into a power grid. When the cable is laid in the underground cable well, the cable is required to be conveyed by the guide device, and the guide device for the cable laying is disclosed in the prior art Chinese patent publication No. CN117638732B, and comprises a fixed base, the top of the fixed base is fixedly connected with a support, the inside of the support is rotationally connected with a connecting wheel, one end of the fixed base is rotationally connected with a connecting seat, and the top of the connecting seat and the top of the fixed base are fixedly connected with connecting frames.
