Description

Technical Field

[0001] The utility model belongs to the field of wind turbine generator sets, and in particular relates to a wireless hand-operated box for variable pitch debugging. Background Art

[0002] As an important component of the wind turbine generator set, the variable pitch system mainly changes the rotation speed of the blades by adjusting the windward angle of the wind turbine blades. Under normal working conditions, it can optimize the power generation efficiency of the entire wind turbine. When a component failure occurs in the wind turbine or the ambient wind speed is too fast, the stall principle can be used to make the wind turbine blades reach the feathering position and stop rotating, thereby preventing the entire wind turbine from stalling and collapsing.

[0003] Furthermore, in current technology, if the variable pitch system fails or needs maintenance, the staff needs to carry the manual operation box with cables from the ground to the hub of the wind turbine, use the cabinet or the terminal for connecting peripherals to connect to the manual operation box, and then perform relevant operations. This means that the operator must perform a series of debugging actions such as opening and retracting the propellers in the hub, which greatly restricts its use and carrying, and there are safety hazards when the operator performs long-term operation and debugging in the hub.

[0004] Therefore, the applicant hopes to seek technical solutions to solve the above technical problems. Utility Model Content
