Abstract

The invention relates to the technical field of wind generating equipment, in particular to a clearance gap sealing device which is used for sealing a clearance gap of a matched connection of an engine room and a tower. The clearance gap sealing device includes a sealing ring which is provided with a cavity used for containing filler, the volume of the sealing ring is enlarged when the cavity is injected with the filler, so that two sides of the sealing ring can be separately closed to the inner wall of the engine room and the outer wall of the tower, a groove is formed in the sealing ring, and absorbents are arranged in the groove. The clearance gap sealing device skillfully uses the sealing ring which is capable of inflating and deflating to seal the clearance gap, the effects of sealingand safety are good, the potential safety hazard of object falling from high altitudes can be effectively eliminated, the problem of cold air in winter and hot air in summer entering the engine roomcan be solved, and the work environment in the engine room is improved; the structure is simple, the cost is low, the installing, maintaining and replacing is extremely convenient, and the inherent structure of the tower does not need to be changed.

Description

technical field [0001] The invention relates to the technical field of wind power generating equipment, in particular to a wind power generating set and a gap sealing device. Background technique [0002] Mechanical products are usually composed of various parts and components. There will inevitably be gaps between the assembled parts. In some cases, the existence of gaps may bring some hazards, such as water leakage and oil leakage, which will affect other parts. If the gap Being at a higher place from the ground, there is also a greater safety risk of falling objects from heights. This situation is more prominent on towering wind turbines. [0003] A wind turbine is a device that converts wind energy into electrical energy. In order to obtain the maximum wind force in real time, a wind turbine is generally equipped with a yaw mechanism. The inner ring of the yaw mechanism is fixed on the outer wall of the tower, and the outer ring is connected to the bottom of the nacelle...
