Abstract

The invention discloses a two-dimensional vibroswitch device for a windmill generator, which comprises a shell, a sliding sleeve, a support seat, a swinging rod, a sliding rod and a pushing rod, wherein the swinging rod swings in the sliding sleeve; the sliding rod is arranged below the swinging rod through a spring seat and driven by the swinging rod to move up and down in the sliding sleeve; the pushing rod is driven by the sliding rod to move up and down in the support seat; the pushing rod is fixed with two contact springs and moving permanent magnets; and the bottom of an inner cavity of the support seat is fixed with fixed permanent magnets and two fixed contact terminals provided with conducting strips. The vibroswitch device has the advantages of compact structure and convenient assembly and use, and can realize quick and accurate actions without being driven by a power supply, so that the damage of the wind mill generator due to excess vibration of a tower is avoided.

Description

technical field [0001] The invention relates to a vibration protection device installed on a tower of a wind power generator, in particular to a two-dimensional vibration switch device for a wind power generator. Background technique [0002] In recent years, wind power generation has achieved rapid development in many areas. However, an important problem in wind power generation is the stability of the wind power generator tower. Due to the high uncertainty of wind energy, if the vibration of the tower in the high wind speed environment is not controlled, the wind turbine will not be able to maintain a stable output power, and even accidents such as damage or breakage of the mechanical structure of the wind turbine system may occur . At home and abroad, some studies on shaft vibration control of wind turbines have been carried out, mostly focusing on dynamic vibration absorbers such as frequency-modulated mass dampers. The control effect of this passive energy dissipation...
