Background technique

The hybrid maglev wind turbine can not only realize the controllable and stable suspension of the rotor, but also help save costs. Considering that the vertical axis wind turbine rotor and blades have a large gravity and the axial force is relatively stable, passive magnetic levitation technology is adopted in the direction of gravity, and the permanent magnetic force is used to support most of the gravity of the rotor and blades to keep the rotor at Vibration within a small range greatly reduces power consumption and simplifies the control structure; in the other four degrees of freedom, active magnetic levitation technology is used to support the rotor and precisely control the position of the rotor, which can be effective, flexible and fast The stable suspension of the controlled rotor can reduce the loss caused by the electromagnetic bearing and further improve the power generation efficiency.

However, the existing vertical axis magnetic levitation wind generator can combine the above advantages to complete the power generation process well. This vertical axis magnetic levitation wind generator often has a digital controller, and the digital controller components are often arranged in the main control cabinet. To make it easy for on-site personnel to perform, the main control cabinet generally has a cover that can be turned open and closed, so that the cover can be opened to allow the on-site personnel to clean or repair the digital controller components in the main control cabinet; however, such The radian of cover plate rotation lacks safe and secure equipment to allow on-site personnel to manipulate and adjust.

Because during the rotation of the cover plate, it is possible to simultaneously form a real-time limit for the location of the flexible connection. In addition, such a limit is achieved through a form fit, so this type of limit is used during operation without additional tools. or equipment, so that the structure is easy to limit in real time. In addition, this type of limit has the nature of surface fit, which prevents shaking and is not difficult for the staff to notice; Referring to the bottom surface S52 of the ditch S4110, this type of limit can form a more reliable structure to prevent the escape from the limit structure due to external effects, so the limit is firm. The solid execution of the architecture is also guaranteed.
