Description
Technical field
The utility model relates to wind-driven generator, particularly a kind of pull-rod type fan blade angle control gear and coaxial double-layer blade structure.
Background technique
Wind-driven generator is a kind of generation of electricity by new energy machine, utilizes wind-force as the energy, has vast potential for future development.Present wind-driven generator mostly is horizontal type, and promptly rotatingshaft is parallel with wind direction, and the ratio that this wind-driven generator need be installed is higher, to guarantee the rotation space of its blade.So wind-driven generator is installed in spacious place usually.For dwindling the volume of wind-driven generator, a kind of vertical wind power generator appears, and the rotatingshaft of vertical wind power generator is vertical with wind direction, generally is to be vertically mounted on the ground.This wind-driven generator takes up room less usually, can install and use in the place that horizontal wind-driven generator can't be installed.
But the blade shroud of vertical wind power generator rotates around a vertical shaft, will occur rotating with contrary wind rotating two states with the wind, and in preceding a kind of state, be the work done state; A kind of state in back advances against the wind, must wasted work.Defective that vertical wind power generator must overcome that Here it is.And vertical wind power generator is except the positive pressure of bearing wind-force, because the wind-engaging angle of fan blade, the whole wind power generator also can bear a cross component force, and this cross component force also can propose higher requirement to the structure and the intensity of wind-driven generator.
The model utility content
For remedying above-mentioned deficiency, the utility model provides a kind of pull-rod type fan blade angle control gear and coaxial double-layer blade structure.
The utility model pull-rod type fan blade angle control gear, comprise framework, fan blade and main shaft, wherein main shaft is provided with a positioning disk, and positioning disk is provided with guide-track groove, and the fan blade limit is provided with pull bar, the other end of pull bar is provided with traveller, traveller is stuck in the guide-track groove, and slides in guide-track groove with the rotation of fan blade, and guide-track groove is the ring broken line shape, guarantee framework in rotation process, fan blade is done in the same way around blade shaft with the tarnsition velocity of framework 1/2 and is rotated.
The utility model coaxial double-layer blade structure, be on same main shaft, divide inside and outside both sides that two frameworks are set, each framework is provided with fan blade separately, respectively be provided with a positioning disk up and down at main shaft, pull bar on the outer fan blade is connected to a positioning disk, and the pull bar of internal layer fan blade is connected to another positioning disk.
Described positioning disk mirror image is up and down installed, and dwindles in proportion in the internal and external frame ratio.
The utility model pull-rod type fan blade angle control gear and coaxial double-layer blade structure adopt pull bar control fan blade angle, and simple in structure, control effectively owing to be convenient to be arranged to double-deck blade structure, overcomes the common cross component force problem of vertical wind power generator.
Description of drawings

Fig. 2 is the schematic representation of internal layer pull-rod type fan blade angle control gear;
Fig. 3 is the schematic representation of coaxial double-layer blade structure.
Embodiment
Below in conjunction with embodiment the utility model pull-rod type fan blade angle control gear and coaxial double-layer blade structure are done more detailed explanation.
Fig. 1 is the schematic representation of pull-rod type fan blade angle control gear.
The utility model pull-rod type fan blade angle control gear, comprise framework 1, fan blade 2 and main shaft 4, main shaft 4 is provided with a positioning disk 5, and positioning disk 5 is provided with guide-track groove 6, and fan blade 2 limits are provided with pull bar 7, the other end of pull bar 7 is provided with traveller 8, traveller 8 is stuck in the guide-track groove 6, and slides in guide-track groove 6 with the rotation of fan blade 2, and guide-track groove 6 is the ring broken line shape, guarantee framework 1 in rotation process, fan blade 2 is done in the same way around blade shaft 3 with the tarnsition velocity of framework 1/2 and is rotated.Like this, when framework 1 rotated 180 °, fan blade 2 rotated 90 °, by transferring to down with the wind with the wind; And after the fan blade that was in downwind position originally rotates 180 °, become on the contrary and facing the wind, thereby realize secund fan blade wind-engaging, the fan blade of another side is wind-engaging not, and framework just can rotate.The control of tension member 7, the rotational angle range of fan blade 2 is swing state for (with complete facining the wind time be 0 °) 0-90 °.
Above-mentioned dress is convenient to be arranged to double-deck blade structure, be exactly on same main shaft 4, divide inside and outside both sides that two frameworks 1,1a are set, each framework is provided with fan blade 2,2a separately, respectively be provided with a positioning disk 5,5a up and down at main shaft 4, pull bar 7 on the outer fan blade 2 is connected to a positioning disk 5, and the pull bar 7a of internal layer fan blade 2a is connected to another positioning disk 5a (see figure 3).
Positioning disk 5 and 5a mirror image are installed up and down, and the same angular orientation of external wind wheel 2, the 2a 180 ° of (see figure 2)s that interlace have just realized that also internal and external frame rotates in opposite directions, thereby overcome the lateral force problem of vertical wind power generator in guaranteeing.
The different big and internal and external frame of positioning disk 5 and 5a dwindles in proportion up and down, and the guide-track groove on it also will be done corresponding correction, to guarantee the fan blade corner on the internal and external frame, all keeps 1/2 of respective frame corner.
