Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation, and more particularly to a cable guiding device for a wind power generation device. Background Art

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the rotation speed through a speed increaser to drive the generator to generate electricity. The electricity generated by the generator needs to be output through cables. During the cable installation process, a guide device is required to guide the cable to prevent damage to the cable.

[0003] When guiding the cable, if the cable tension is not appropriate, the cable is prone to shaking and slipping. It is difficult for existing devices to adjust the tension of the cable, which affects the stability of the cable guidance during use.

[0004] After searching, the Chinese patent with the announcement number CN215595802U discloses a guiding device for cables of wind turbine generator sets. Through the cooperation of a ring, a turntable, a wheel, an annular groove, a pulley, a gear A, a gear B and a motor, the rotation of two sets of wheels can be adjusted and controlled to apply pressure to the cable during winding and reduce pressure during unwinding, and the tension of the cable is controlled to be appropriate to avoid slipping and shaking when guiding the cable, making the guidance more stable.

[0005] When the above-mentioned guide device for wind turbine cables is actually used, the cables may be subjected to excessive friction and compression during the unwinding and rewinding process, resulting in surface wear, internal damage or breakage of the cables. At the same time, the existing guide device uses a spring to clamp the wires, causing the cables to fall off due to loose clamping. Summary of the invention
