Abstract
Vertical shaft centrifugal force becomes oar power generation fan, form primarily of fan supporter, generator, motor shaft, blade rack and blade, centrifugal force blade pitch device is set between blade rack and blade, centrifugal force blade pitch device comprises connecting pin, nylon jacket and wind spring, wind spring is arranged in nylon jacket, blade rack has the connecting pin of nylon jacket to be connected with blades installation frame by overlapping, and blade installed by blades installation frame, and blade rack arranges limiting board.The utility model by arranging centrifugal force blade pitch device between vane of vertical shaft wind-driven generator support and blade; realize the rotating speed that automatically adjustment exceeds wind-driven generator after rated wind speed; widen wind-driven generator wind speed and utilize scope; improve the performance of wind-driven generator safe operation, protect wind-driven generator and consumer.There is the advantage that structure is simple, change oar is flexible and with low cost.
Description
Technical field
The utility model relates to technical field of wind power generator, is specifically related to a kind of vertical shaft centrifugal force and becomes oar power generation fan.
Background technique
Wind energy, as a kind of clean reproducible energy, is the effective alternative energy source solving energy crisis, and the development and investigation of wind energy conversion system has become the focus of various countries' research.Vertical axis windmill relies on convenient for installation and maintenance, and blade processing is easy, and the advantages such as noise is low are provided with the potentiality compared favourably with commercial horizontal-shaft wind turbine.But vertical axis windmill startability difference compares the lower inferior position of horizontal-shaft wind turbine with wind energy utilization, limit the development of vertical axis windmill, but research shows that feather technology solves wind energy conversion system starting problem, reduce the generation of blade vibration and dynamic stall, improve the effective ways of vertical axis windmill combination property.
Summary of the invention
The utility model provides a kind of vertical shaft centrifugal force and becomes oar power generation fan, to solve the problem of the startability difference that prior art exists.
The utility model forms primarily of fan supporter, generator, motor shaft, blade rack and blade, solving the technological scheme that its technical problem adopts is arrange centrifugal force blade pitch device between blade rack and blade, centrifugal force blade pitch device comprises connecting pin, nylon jacket and wind spring, wind spring is arranged in nylon jacket, blade rack has the connecting pin of nylon jacket to be connected with blades installation frame by overlapping, blade installed by blades installation frame, and blade rack arranges limiting board.
Working principle of the present utility model exceedes rated speed when motor rotational shaft speed, and blade drives blades installation frame to take connecting pin as the active force rotation change oar that the center of circle overcomes wind spring under the influence of centrifugal force; When rotating speed reduces, the active force of wind spring orders about the counterrotating of blades installation frame band moving vane, and rotating speed continues to reduce, and blades installation frame rotates to limiting board under the active force of wind spring, i.e. initial makeup location.
The utility model by arranging centrifugal force blade pitch device between vane of vertical shaft wind-driven generator support and blade; realize the rotating speed that automatically adjustment exceeds wind-driven generator after rated wind speed; widen wind-driven generator wind speed and utilize scope; improve the performance of wind-driven generator safe operation, protect wind-driven generator and consumer.There is the advantage that structure is simple, change oar is flexible and with low cost.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model centrifugal force blade pitch device;
Fig. 3 is the schematic top plan view of the utility model centrifugal force blade pitch device.
1 fan supporter, 2 generators, 3 motor shafts, 4 blade racks, 5 centrifugal force blade pitch devices, 6 blades, 7 blades installation framves, 8 limiting boards, 51 connecting pins, 52 nylon jacket, 53 wind springs in figure.
Embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of vertical shaft centrifugal force becomes oar power generation fan, form primarily of fan supporter 1, generator 2, motor shaft 3, blade rack 4 and blade 6, centrifugal force blade pitch device 5 is set between blade rack 4 and blade 6, centrifugal force blade pitch device 5 comprises connecting pin 51, nylon jacket 52 and wind spring 53, wind spring 53 is arranged in nylon jacket 52, blade rack 4 is connected by the connecting pin 51 being installed with nylon jacket 52 with blades installation frame 7, blade 6 installed by blades installation frame 7, blade rack 4 arranged limiting board 8.
Working principle of the present utility model exceedes rated speed when motor rotational shaft speed, and the active force that blade 6 drives blades installation frame 7 to overcome wind spring 53 with connecting pin 51 for the center of circle under the influence of centrifugal force rotates change oar.When rotating speed reduces, the active force of wind spring 53 orders about blades installation frame 7 and is with moving vane 6 counterrotating.Rotating speed continues to reduce, and blades installation frame 7 rotates to limiting board 8 under the active force of wind spring 53, i.e. initial makeup location.
