摘要

The disclosure relates to a mounting frame, an energy storage unit, a pitch system, a wind turbine and a method. The mounting frame for mounting accumulators in a hub includes: a base having a predetermined thickness, wherein the base includes a mounting surface in a thickness direction of the base; and two or more accumulator mounting elements disposed on the mounting surface at intervals, wherein each accumulator mounting element includes a supporting assembly and a holding assembly connected to the supporting assembly, the supporting assembly is connected to the mounting surface and extends in the thickness direction, and the holding assembly is adapted to clamp and fix the accumulator such that all the accumulators in the hub are mounted to the mounting frame. For the mounting frame, energy storage unit, pitch system, wind turbine and method according to embodiments of the disclosure, the mounting frame may simultaneously mount the accumulators corresponding to the hydraulic actuators of respective blades, which occupies a small space, has a low cost, and enables easy installation and maintenance of the accumulators.
