Abstract

The speed limiting protection device comprises a fixed shell, a speed limiting box is fixedly connected to the interior of the fixed shell, a fixed block is rotationally arranged on the lower inner wall of the speed limiting box, a rotating rod is slidably connected to the fixed block, and a rotating shaft is arranged on the rotating rod. The rotating rod penetrates through the speed limiting box and the upper inner wall of the fixed shell and extends out of the fixed shell, a plurality of fixed impellers are fixedly connected to the side wall of the end, located on the outer side of the fixed shell, of the rotating rod, a connecting rod is fixedly connected to the other end of the fixed block, and the connecting rod penetrates through the lower inner wall of the fixed shell. The rotating rod can be adjusted according to the rotating speed of the rotating rod, the force applied to the rotating rod is not changed when the rotating rod is subjected to speed limiting, speed limiting is facilitated, the rotating rod can be retracted into the fixed shell when wind power is too large, it is avoided that the rotating rod is excessively exposed to the outer side, and therefore the effect of protecting the rotating rod is achieved.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a speed limiting protection device for wind power generators. Background technique [0002] With the development of the times, people's application of clean energy is becoming more and more common, and wind power is a kind of clean energy, which is widely used in western my country. The rotor rotates and finally outputs the electrical equipment of alternating current. [0003] When the wind turbine is too strong, the rotating speed of the rotating rod is too fast, which may cause damage to the rotating rod, so it needs to be limited in speed. Adjusting the rotation speed is not conducive to the speed limit of the rotation. At the same time, the protection effect of the speed limit device on the rotating rod is lacking, and the rotating rod may also be damaged when the wind blows directly. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to solve th...
