Description

Technical Field

[0001] The present disclosure relates to the technical field of wind turbine tower equipment, and in particular to a wind turbine tower maintenance device. Background Art

[0002] Wind power generation refers to a power generation method that uses wind turbines to directly convert wind energy into electrical energy. Among them, the wind turbine tower, as the supporting structure of the wind turbine, is exposed to the natural environment for a long time, which can easily lead to damage and contamination of the anti-corrosion coating on the outer wall of the steel tower, paint peeling, and cylinder corrosion. In addition, exceeding the service life of the coating will cause the coating to powder, fall off, bubble and loosen, which will accelerate the corrosion of the cylinder metal. Therefore, the surface of the wind turbine tower needs to be repaired and cleaned regularly.

[0003] In related technologies, manual maintenance and cleaning methods are usually adopted. Workers use tools such as lifting ropes to suspend in the air near the tower to carry out construction, and usually workers need to carry about tens of kilograms of repair materials. The suspension method is not only labor-intensive and inefficient, but also has certain safety hazards because wind turbine towers are usually high and located in areas with high wind speeds.

[0031] Through the above technical solution, in the wind turbine tower maintenance device provided by the present disclosure, the holding rope 2 is wound around the circumference of the wind turbine tower 5, and the work platform 1 is slidably connected to the holding rope 2 via the sliding mechanism 3, wherein the first rotor 32 and the second rotor 33 are used to clamp the holding rope 2, and the second rotor 33 is rotatably connected to the work platform. In this way, the first rotor 32 can rotate under the action of the first driving device 31, and drive the work platform 1 to move along the extension direction of the holding rope 2 under the action of the friction between itself and the holding rope 2. The holding rope 2 is wound around the circumference of the wind turbine tower 5, thereby achieving the purpose of moving the work platform around the circumference of the wind turbine tower 5. The second rotor 33 is rotatably mounted on the work platform 1. On the one hand, it can cooperate with the first rotor 32 to clamp the holding rope 2, thereby increasing the friction between the first rotor 32 and the holding rope 2.

In addition, the device also includes two sets of traction components fixed to the top of the wind turbine tower 5 and respectively connected to the holding rope 2 and the work platform 1. The two sets of traction components drive the holding rope 2 and the work platform 1 to move axially along the wind turbine tower 5, and finally realize the all-round movement of the work platform 1 along the wind turbine tower 5. In this way, the work platform 1 can be used as a platform for staff to work or place repair materials, reducing the work intensity of staff in maintaining the wind turbine tower 5 and improving work efficiency.

[0032] In the wind turbine tower maintenance device provided by the present disclosure, the first rotor 32 and the second rotor 33 can clamp the holding rope 2 in any suitable manner, and the present disclosure does not impose any specific restrictions on this. As an exemplary embodiment, refer to Figure 1 As shown in FIG, the first rotating wheel 32 may be provided with a groove around its periphery, into which the holding rope 2 can be inserted. The second rotating wheel 33 abuts against the holding rope 2 to clamp and secure the holding rope 2. The groove prevents the holding rope 2 from slipping out of the first rotating wheel 32, thereby improving the reliability of the slidable connection between the holding rope 2 and the workbench. The second rotating wheel 33, in conjunction with the first rotating wheel 32, clamps the holding rope 2.

[0033] In some other embodiments, the holding rope 2 can also be constructed as a chain, and the circumferential side of the first rotating wheel 32 is provided with teeth that are pre-matched with the chain. In this way, the first rotating wheel 32 can also achieve the purpose of moving along the length direction of the chain under the drive of the first driving device 31.

In this way, when the holding rope 2 needs to move along the axial direction of the wind turbine tower 5, the second driving device 13 drives the movable frame 12 to move toward the wind turbine tower 5, the first rotor 32 and the second rotor 33 are both fixed to the movable frame 12, and the holding rope 2 is clamped between the first rotor 32 and the second rotor 33, so that it can move toward the wind turbine tower 5 under the drive of the movable frame 12 to achieve the relaxation of the holding rope 2 relative to the surface of the wind turbine tower 5.

The second drive device 13 works to tighten the holding rope 2 so that the holding rope 2 is relatively fixed to the surface of the wind turbine tower 5. Then the fourth drive device 44 is reversed to loosen the second traction rope 43. The work platform moves along the circumference of the wind turbine tower 5 under the action of the first drive device 31, thereby realizing comprehensive maintenance of the wind turbine tower 5 in this maintenance position.

[0040] The third drive device 42 and the fourth drive device 44 can be configured in any suitable form, and this disclosure does not impose any specific limitations thereon. As an exemplary embodiment, the third drive device 42 and the fourth drive device 44 can both be configured as winches, each connected to the first traction rope 41 and the second traction rope 43, respectively, to control the length of the first traction rope 41 and the second traction rope 43 by switching between forward and reverse rotation.
