Speed regulating device of generator set

The utility model relates to the field of generator set speed regulation, in particular to a generator set speed regulation device. The generator set speed regulation device comprises a bottom plate, a mounting assembly and a clamping assembly, a plurality of fixedly-connected mounting plates are mounted on one side of the bottom plate, fixedly-connected fixing frames are mounted on the mounting plates, limiting plates are arranged on the fixing frames, and fixedly-connected clamping plates are mounted on the sides, close to the shell, of the limiting plates. According to the generator set speed regulation device, the limiting plate is rotated to enable the limiting plate and the mounting plate to be in a folded state, then the shell is rotated to enable the shell to be attached to the surface of the bottom plate, at the moment, the spring is sleeved with the containing hole, the spring is extruded, then the limiting plate is loosened, the spring drives the limiting plate to rebound, and the clamping plate is
