The invention belongs to the technical field of new energy, and discloses an offshore floating type wind generating set. The wind generating set comprises a main frame, wherein a horizontal detection device is fixedly installed in the middle of the bottom of the main frame, buoyancy assemblies are fixedly installed on the inner periphery and the outer periphery of the three edges of the bottom of the main frame respectively, high-strength chromium-plated nylon steel wire ropes are fixedly installed in the middles of the three edges of the bottom of the main frame respectively, and the middles of the three high-strength chromium-plated nylon steel wire ropes are sleeved with balance weight assemblies in a limiting mode respectively. By arranging a seabed pulling device, the high-strength chromium-plated nylon steel wire ropes, the balance weight assemblies and the like, the purpose of good overall stabilizing effect is achieved, the influence of influence and damage on the wind generating set is reduced, and at the moment, the high-strength chromium-plated nylon steel wire ropes are straightened and tightened again to serve as overall stable support. Due to the arrangement of the limiting barrel, the balance weight assemblies can automatically adapt to the change of the direction of a water body, the influence of resistance is reduced to the maximum extent, and long-term stable use of the wind generating set is ensured.
