Damping integrated device, damper, and wind power generator set

Disclosed are a damping integrated device (100), a damper (1) and a wind power generator set. The damping integrated device (100) comprises: a base body (10) having a predetermined length and comprising an inner cavity (10a) extending in the lengthwise direction (X) thereof; a frequency adjustment component (20) arranged in the inner cavity (10a), the frequency adjustment component (20) comprising an elastic member (21) and an adapter (22), which are connected to each other, with one end of the elastic member (21) in the lengthwise direction (X) being connected to the base body (10), and the other end thereof being connected to the adapter (22); a first connector (30) extending into the inner cavity (10a) and at least partially protruding out of the base body (10) in the lengthwise direction (X), the first connector (30) being connected to the adapter (22) and capable of moving relative to the base body (10), so as to make the elastic member (21) stretch or shrink in the lengthwise direction (X); and a damping component (40) arranged in the inner cavity (10a), the damping component (40) being connected to the adapter (22) and at least partially abutting against an inner wall of the base body (10), and the damping component (40) being used to absorb kinetic energy of the first connector (30). The damping integrated device (100) can meet the requirements for frequency adjustment, damping, etc., and also has a simple structural design and is easy to maintain.
