Description

Technical Field

[0001] This utility model belongs to the field of wind power generation technology, and specifically relates to an omnidirectional micro wind power generation blade. Background Technology

[0002] Common wind power generation devices are divided into two types: vertical axis wind power generation and horizontal axis wind power generation. Because horizontal axis wind power generation equipment requires yaw and pitch control, its structure is complex and its self-starting performance is poor, making it unsuitable for small wind farms. Vertical axis wind power generation equipment has a relatively simple structure and has advantages such as automatic wind direction adjustment, no noise, high safety and reliability, and convenient maintenance, making it particularly suitable for small wind farms and distributed energy applications. However, currently, vertical axis wind power generation equipment generally suffers from low wind energy utilization efficiency, resulting in low power generation efficiency.

[0003] A search revealed a vertical axis wind turbine rotation synchronization mechanism (CN222045996U) that uses wind power to control the rotation of curved fan blades, driving corresponding internal gear sleeves or connecting sleeves. Due to the meshing of the gears and internal gear sleeves, the curved fan blades connected to the connecting sleeves rotate synchronously with those connected to the internal gear sleeves. This synchronously drives the connecting shaft, second conical teeth, first conical teeth, and rotating rod to rotate, thereby generating electricity through the generator. However, the device only uses connecting columns to connect and fix the curved fan blades, so strong winds may cause structural damage to the device, rendering it unusable.

[0004] A search revealed a vertical axis wind turbine wing structure with the existing technology announcement number CN221942621U. This device is installed and fixed at the usage location using a mounting plate and fixing holes. After completion, the wind blows the fan blades to rotate, which in turn drives the generator to generate electricity. The springs and dampers in the device can absorb the vibration and impact of the wind on the fan blades, and the vibration motor works with the heating plate to shake off the melted ice. However, the structure and fixing direction of the fan blades in this device are singular. Therefore, when the wind speed is too low, the wind is not enough to drive the fan blades to rotate, resulting in a decrease in power generation efficiency.

[0005] Therefore, a omnidirectional micro-wind power generation blade is needed. This blade can intercept low-speed winds, control the device to perform normal power generation, and reinforce the connection structure in the device to prevent damage to the device caused by excessive wind speed.
