Technical Field

[0001] The utility model belongs to the technical field of slip ring supports, and in particular relates to a slip ring support frame. Background Art

[0002] Due to the large current and multiple loops, the wind turbine slip ring is too large, too long and too heavy. There is a long section of stator loop hanging in the air behind the installation position on the rotor side, which causes the wind turbine slip ring itself to have a large self-gravity, causing a certain degree of damage to the installation position and affecting the service life of the wind turbine slip ring.

[0003] The existing wind turbine slip rings are installed with only 6-8 mounting holes at the fixed end, and then fixed. This method requires that the end of the rotating shaft where the slip ring is installed is installed and fixed in one direction, but the stator end of the slip ring is suspended in the air. Due to the effect of gravity, the slip ring itself is subjected to a downward force, which will affect the installation life of the slip ring over time. For this kind of influence on the slip ring installation caused by the slip ring's own weight.

[0004] Therefore, a slip ring support frame is needed to solve the problems in the prior art that the slip ring is easily worn out due to suspension and deadweight after installation, which affects the service life and is inconvenient to install and carry. Utility Model Content
