Description

Wind-powered electricity generation blade's angle regulation device Technical Field The utility model relates to the technical field of wind power blades, in particular to an angle adjusting device of a wind power blade. Background Wind power blades are key components for capturing wind energy in a wind turbine generator, and wind power blows the blades to rotate so as to generate electricity. Wind used in nature is uncontrollable in the actual use process, the wind is big and small, the installed blades cannot be changed, the wind can cause the blades to rotate too fast to cause damage, and the wind can cause the electric energy generated by low rotation speed of the blades to be low. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides an angle adjusting device for a wind power blade. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a wind-powered electricity generation blade's angle regulation device, includes the hub seat, the outside of hub seat is provided with a plurality of blade, the blade pass through coupling assembling with the hub seat is connected the inside of hub seat is provided with and is used for driving the rotatory drive assembly of blade, be provided with in the hub seat and be used for right the blade is fixed subassembly. Further, a plurality of holes matched with the blades are formed in the peripheral surface of the hub seat, and the roots of the blades are penetrated and rotatably connected with the holes. Further, the connecting assembly comprises a connecting plate rotationally connected with the hole, a plurality of notches are formed in the end face of the connecting plate, a plurality of bolts matched with the notches are fixedly connected to the root end face of the blade, the bolts are slidably connected with the notches, and nuts are connected to the bolts in a threaded mode. Further, the driving assembly comprises a motor fixedly connected with the hub seat, a worm is fixedly connected with the shaft end of the motor, and a worm wheel meshed with the worm is rotationally connected with the hub seat. Further, the driving assembly further comprises a rotary table fixedly connected with the worm wheel, a notch is formed in the end face of the rotary table, and the bolt is clamped with the notch. Further, the fixed assembly comprises an electric push rod fixedly connected with the hub seat and a gear ring fixedly connected with the outer peripheral surface of the connecting plate, a tooth is fixedly connected with the telescopic end of the electric push rod, and the tooth is meshed with the gear ring. The angle adjusting device for the wind power blade has the beneficial effects that the angle of the blade is adjusted through the driving assembly, and the blade is leveled when wind is large, so that damage to the blade due to too high wind rotating speed is reduced, stable operation of equipment under various wind speeds is ensured, the angle of the blade can be adjusted when wind is small, the lift coefficient of the blade is optimized by increasing the capture of the blade to wind energy, and the energy conversion efficiency is improved.
