AI Technical Summary

⚠Technical Problem

Vertical axis wind turbines for household use often lack all-directional wind detection and speed limit safety devices due to cost constraints, leading to potential over-rotation, power imbalance, and increased risk of fire, which reduces the lifespan of the equipment.

⚗Method used

A rotational speed protection device with a support sleeve, rotating shaft, adjustment components, blades, gear transmission, control components, and locking mechanisms that adjust and lock the rotational speed to prevent over-rotation and maintain power balance, using pneumatic and electrical systems to monitor and control wind turbine operation.

🎯Benefits of technology

The device effectively maintains appropriate rotational speed and power balance, preventing over-rotation and fire risks, thereby extending the lifespan and safety of the wind power generation equipment.

Abstract

This invention discloses a rotational speed protection device for a small wind power generation facility and relates to the field of wind power generation facilities. The rotational speed protection device for a small wind power generation facility includes a support sleeve, wherein a rotating shaft is rotatably connected to the top of the support sleeve, an adjustment component is fixedly attached to the outer wall of the top of the rotating shaft, a blade is fixedly connected to the other end of the adjustment component, a gear transmission is fixedly connected to the bottom of the rotating shaft, the output end of the gear transmission is fixedly connected to a wind turbine via a coupling, a battery group is provided at the bottom of the wind turbine, the wind turbine and the battery group are electrically connected, and a control component is fixedly attached to the top of the rotating shaft. In this invention, the design of the lock component causes the rotating shaft to lock and stop rotation when the wind speed is excessive. This protects the wind turbine and prevents the wind turbine from losing its balance due to over-rotation of the rotating shaft and from causing a fire due to overpower.
