Abstract

A variable speed increasing device of a fan blade of a wind driven generator relates to auxiliary equipment for wind power generation and is provided with a plurality of weight balancing balls in a fan blade of a fan; and a booster spring is arranged at the end point in the fan blade of the fan to avoid the weight balancing balls clamping in a bin. The variable speed increasing device utilizes the lever force generated by the gravities of the weight balancing balls and combines the booster of the spring to help the fan blade of the fan to realize variable speed increasing and ensure continuous power generation under the conditions of small wind power.

Description

Wind-driven generator flabellum variable speeder
Technical field
The utility model relates to a kind of wind-power electricity generation supplementary equipment.
Background technique
Conventional wind-driven generator flabellum is a hollow structure, fully by wind-drive, when wind-force less than three grades, the wind-driven generator flabellum both had been difficult to start, wind-power electricity generation can not continue, and can not guarantee continuous power supply.
Summary of the invention
The purpose of this utility model provides a kind of wind-driven generator flabellum variable speeder, works as a wind-force hour wind-driven generator flabellum with the solution prior art and both has been difficult to start, and wind-power electricity generation can not continue, and can not guarantee problems such as power supply continuously.
The utility model mainly is made up of fan leaf, and solving the technological scheme that its technical problem adopts is that several weighted spherical ball are set in the fan leaf of hollow, and the end points place is provided with power assistant spring in the fan leaf, avoids weighted spherical ball Ka Cang.
Adopting good effect of the present utility model is the action of gravity that utilizes weighted spherical ball, in conjunction with the power-assisted effect of spring, makes fan leaf realize the variable speedup, and guaranteeing can uninterrupted power generation under little wind-force.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is the utility model structural representation;
1 power assistant spring, 2 weighted spherical ball, 3 fan leafs among the figure.
Embodiment
As shown in the figure; Spring is arranged at the top of fan leaf, and three ganoid weighted spherical ball are set in the fan leaf, and weighted spherical ball adopts lead metal materials processing to form, and fan leaf and other modular construction are same as the prior art.
During work, as long as fan leaf rotates on the horizontal line, weighted spherical ball promptly is rolled near the blower fan axle, the opposite side flabellum goes to below the horizontal line, the fan page or leaf top that weighted spherical ball can be rolled, the lever that the arm of force difference that utilization forms produces, realize the variable speedup, guarantee power supply continuously under little wind-force weather.
