Abstract
The utility model discloses a novel flywheel, include rim plate and the location shaft hole that is provided with the axle center, the rim plate is fretwork formula rim plate, be provided with many strengthening ribs in the cavity of fretwork formula rim plate, it is a plurality of the near -end of strengthening rib with main shaft fixed connection, it is a plurality of the distal end of strengthening rib along the rampart fixed connection of rim plate. The utility model discloses a fretwork formula rim plate and balancing weight reduce the instability of wind power generation in -process blade rotational speed and reduce the blade vibration range and the momentum that shakes, and then the power output who has guaranteed aerogenerator is stable, has guaranteed wind power generation quality and wind power generation efficiency.
Description
Technical field
This utility model relates to the auxiliary equipment of a kind of wind-power electricity generation, refers more particularly to a kind of flywheel.
Background technology
In the prior art, traditional wind-driven generator utilizes wind-force to drive air vane to rotate, then the speed rotated is promoted through booster engine, and then promotes electrical power generators.According to current windmill technology, it is about the mild wind speed (degree of mild wind) of three meters per second, just can start generating.
But, there are some technological deficiencies successively in the wind-driven generator in conventional art；Such as: the wind-driven generator in conventional art, usually because wind-force is unstable, causes blade rotational speed unstable, and the frequency in turn resulting in wind-driven generator is unstable.Such as: the wind-driven generator of three or five blades, because the shape of blade is different, the blade rotational speed produced when natural wind speed is 3-4 meter per second is not tens to hundreds of rpm not etc., above-mentioned blade rotational speed scope is bigger obviously, rotation speed change amplitude is relatively big, and the frequency and amplitude so easily causing blade is big.
Utility model content
The purpose of this utility model is that the frequency and amplitude providing a kind of blade in order to solve the problems referred to above is little, the flywheel that rotating speed output is stable.
This utility model is achieved through the following technical solutions above-mentioned purpose:
This utility model includes wheel disc and is provided with the positioning shaft hole in axle center, described wheel disc is hollow type wheel disc, it is provided with many reinforcements in the cavity of described hollow type wheel disc, the near-end of the plurality of described reinforcement is fixing with described positioning shaft hole to be connected, the far-end of multiple described reinforcements, along the fixing connection of ring wall of described wheel disc, described wheel disc is provided with balancing weight.
Specifically, described wheel disc is alloy wheel disc, cast iron wheel disc, carbon fiber wheel disc, glass fibre wheel disc or rustless steel wheel disc.
Specifically, described balancing weight is arranged on the circumferential edges of described wheel disc.
Specifically, described balancing weight is continuous way annular distribution.
This utility model passes through hollow type wheel disc and balancing weight, reduces the unstability of wind-power electricity generation process Leaf rotating speed and reduces blade vibration amplitude and shaking volume；And then ensure that the electric power output of wind-driven generator is stable, it is ensured that wind-power electricity generation quality and wind power generation efficiency.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model；
Fig. 2 is operating diagram of the present utility model；
In figure: 1-wheel disc, 2-positioning shaft hole, 3-reinforcement, 4-impeller, 5-flywheel, 6-balancing weight.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As illustrated in fig. 1 and 2, this utility model includes wheel disc 1 and is provided with the positioning shaft hole 2 in axle center, described wheel disc 1 is hollow type wheel disc, it is provided with many reinforcements 3 in the cavity of described hollow type wheel disc 1, the near-end of the plurality of described reinforcement 3 is fixing with described positioning shaft hole 2 to be connected, the far-end of multiple described reinforcements, along the fixing connection of ring wall of described wheel disc 1, described wheel disc 1 is provided with balancing weight 6.
Described wheel disc is described wheel disc is alloy wheel disc, cast iron wheel disc, carbon fiber wheel disc, glass fibre wheel disc or rustless steel wheel disc, make flywheel 5 have relatively large rotating inertia, in the rotation of the too small situation impeller 4 of wind-force, increase the utilization rate of wind-force, thus improving generated energy, rotating speed is steady.
Described balancing weight is arranged on the circumferential edges of described wheel disc, and described balancing weight is continuous way annular distribution.
Operation principle of the present utility model is as follows:
Owing to the acting of impeller 4 is discontinuous, so impeller 4 rotating speed also changes, when impeller 4 rotating speed increases, flywheel 5 kinetic energy increases energy storage or saving to get up, when impeller 4 rotating speed reduces, flywheel 5 kinetic energy reduces, and energy is disengaged, and flywheel 5 can be used to reduce wind wheel and fluctuates at operation process medium speed；Hollow type wheel disc 1 rotating speed starts fast, and balanced action and flywheel effect at balancing weight 6 reduce the unstability of wind-power electricity generation process Leaf rotating speed and reduce blade vibration amplitude and shaking volume；And then ensure that the electric power output of wind-driven generator is stable, it is ensured that wind-power electricity generation quality and wind power generation efficiency.
These are only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included in protection domain of the present utility model.
