Abstract
The utility model relates to acentrifugal propeller-changing device for central and main spring blades, which belongs to the technical field of the wind power generator. A bearing shaft for blades and blades of the utility model are arranged in a hub, and guide pins are arranged on blade handles and inserted into two spiral grooves arranged in the bearing shaft for blades. A revolving shaft is arranged on the front end of a wind power generator, and a spring is arranged on a rotating shaft of which the front end is connected with the blades by wire ropes. Because only one spring is used for controlling a plurality of blades in the utility model, the deflection angles of the blades can be ensured, and the wind power generator can run normally. In addition, the utility model has the advantages of simple structure and convenient installation.
Description
The utility model is a kind of central main spring blade centrifugal variation paddle device, belongs to the wind-driven generator field.
At present the speed change gear of a kind of wind-driven generator that uses is that a spring all is housed on each petiole, and the angle of facining the wind that relies on spiral chute on it and position-limitting pin to control blade, reaches the too fast purpose of restriction wind-driven generator rotating speed with this.Because spring hardness inconsistent makes the variation of blade angle inconsistent, thereby forms a moment on generator shaft, generator is caused to a certain degree harmful effect.Also relative complex of its structure is installed cumbersome in addition.
In order to overcome the deficiency of above-mentioned wind-driven generator speed change gear, the utility model spy has proposed a kind of central main spring blade centrifugal variation paddle device.
The utility model central authorities main spring blade centrifugal variation paddle device mainly is made of spring, wire rope, blade, guide pin, supporting blades axle and turning axle; Supporting blades axle and blade are contained in the wheel hub, and guide pin is contained on the petiole, and are inserted in two spiral chutes opening in the supporting blades axle; Turning axle is loaded on the front end of wind-driven generator, and spring is contained in the rotating shaft, and its front end is linked by wire rope and blade.
The working procedure of this central main spring blade centrifugal variation paddle device: when wind-force exceeded the speed limit, blade outwards stretched under action of centrifugal force.Because the effect of guide pin, blade will rotate a certain angle, and reduce its windward side, to reach the purpose of deceleration.When wind-force recovers into, blade returns to normal working position under the effect of spring and wire rope.
This central main spring blade centrifugal variation paddle device, owing to only control a plurality of blades with a spring, thereby can guarantee the angle of a plurality of blade deflections, wind-driven generator can be run well.This central main spring blade centrifugal variation paddle apparatus structure is simple in addition, is convenient to install.
Fig. 1 is this central main spring blade centrifugal variation paddle device general assembly schematic representation.
Embodiment: (see figure 1)
The utility model central authorities main spring blade centrifugal variation paddle device mainly is made of spring 1, wire rope 2, blade 3, guide pin 4, supporting blades axle 5 and turning axle 6; Have two 45 ° spiral chute 7 in the supporting blades axle 5, supporting blades axle 5 and blade 3 are contained in the wheel hub 8, and guide pin 4 is contained on the petiole 9, and are inserted in two spiral chutes 7 opening in the supporting blades axle 5; Turning axle 6 is loaded on the front end of wind-driven generator 10, and the two ends of spring 1 are fixed on the spring seat 11 on the turning axle 6, and the free end of spring 1 connects by wire rope 2 with blade 3 roots.
