Abstract
The invention provides a telescopic variable blade device which comprises a crankshaft, a base, blades and a roller. The two ends of the crankshaft are fixed to two supporting bases respectively, the two supporting bases are fixed to the base, the roller is arranged on the crankshaft through a bearing, the roller is provided with a groove, the blades and the groove form a moving pair, the blades can extend out of the roller through the moving pair, the crankshaft and the blades are connected through a connection rod, the connection rod is hinged to the crankshaft and the blades, the axis of an eccentric shaft of the crankshaft and the axis of the roller are not in the same line, the number of the blades is at least two, the length of the portion, extending out of the roller, of the upper blade is larger than that of the lower blade, and one end of the roller is provided with a gear used for power output. According to the device, the crankshaft and the roller are arranged eccentrically, so that the length of the portion, extending out of the roller, of the upper blade is always larger than that of the lower blade, and as long as force acts on the blades, torque is formed to drive the roller to rotate.
Description
Technical field
What the present invention relates to is a kind of rotor machine, specifically blade expansion adjusting system.
Background technique
Along with the scarcity day by day of traditional petrochemical industry resources such as coal, the cry of development new energy is more and more higher.In new energy, morning and evening tides and wind-force belong to renewable resources, and clean reliable, have considerable strategic position for the mankind's sustainable development.But because the history of new energy development is also too short, current is that tital generator blade or wind power generator oar blade are all the fixing distance of starching mostly, has the shortcomings such as energy utilization rate is low, starting torque is large.Therefore, new energy be greatly developed, just the problems such as its efficiency is low, starting torque is large must be solved.
Summary of the invention
The object of the present invention is to provide and can overcome morning and evening tides and a kind of self extending formula of the shortcoming such as wind power generator oar blade efficiency is low, starting torque is large becomes paddle device.
The object of the present invention is achieved like this:
A kind of self extending formula of the present invention becomes paddle device, it is characterized in that: comprise bent axle, base, blade, cylinder, the two ends of bent axle are separately fixed on two bearings, two bearings are fixed on base, cylinder is arranged on bent axle by bearing, on cylinder, have groove, blade and groove form sliding pair, blade can stretch out outside cylinder by sliding pair, bent axle is connected by connecting rod with blade, connecting rod and bent axle and blade are all hinged, the eccentric shaft axis of bent axle and the axis of cylinder be not on same straight line, described blade has two at least, the distance that blade above being positioned at stretches out cylinder is all the time than the length of the blade of below, one end of cylinder is provided with the gear for power output.
The present invention can also comprise:
1, described blade has six, and six blades are uniformly distributed with respect to roll circumference.
Advantage of the present invention is: the present invention is bent axle and cylinder arranged off-centre, has realized distance that upper half part blade stretches out cylinder all the time than the length of lower half portion blade, just can form torque and drives cylinder to rotate as long as act on effectively blade.The present invention has abandoned traditional mentality of designing completely, have can two-wayly generate electricity, starting torque is little, capacity usage ratio advantages of higher, has epoch-making meaning for greatly developing of morning and evening tides and wind generating unit.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is sectional view of the present invention;
Fig. 3 is part assembling schematic diagram of the present invention.
Embodiment
For example the present invention is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1～3, its chief component of the present invention has: bearing 1, bent axle 2, gear 3, cylinder 4, blade 5, base 6, connecting rod 7.Bent axle 2 is connected on bearing 1, and need ensure when mounted the opposite direction of bent axle 2 towards base 6.Cylinder 4 is arranged on the bearing at bent axle 2 two ends.The large end of connecting rod 7 is hinged with bent axle 2, and the bearing pin of small end and blade 5 is hinged.The fluting formation sliding pair that blade 5 is circumferential with cylinder 4.In the time of water impact blade 5, because eccentric shaft axis and cylinder 4 axis of bent axle 2 have certain offset distance, ensure to be positioned at distance that cylinder 4 upper half part blades 5 stretch out cylinder 4 all the time than the length of lower half portion blade 5, just make upper half part blade 5 stressed large compared with lower half portion as long as therefore have current or wind to impact blade 5, thereby producing torque drives cylinder 4 to rotate, cylinder 4 rotates and has just driven conversely the flexible of blade 5, thereby has realized the automatic variation of blade 5.On cylinder 4, gear 3 is installed simultaneously, by it, transmission of power just can be realized to generating to generator.
Bent axle is connected on bearing, and cylinder is arranged on the bearing of crankshaft two end.Connecting rod tip and bent axle are hinged, and the bearing pin of small end and blade is hinged.The circumferential fluting of blade and cylinder forms sliding pair.In the time of water impact blade, because eccentric shaft axis and the cylinder axis of bent axle have certain offset distance, ensure that distance that upper half part blade stretches out cylinder is all the time than the length of lower half portion blade, just make upper half part blade stressed large compared with lower half portion as long as therefore have current or wind to impact blade, thereby producing torque drives cylinder to rotate, cylinder rotates and has just driven conversely the flexible of blade, thereby has realized the automatic variation of blade.On cylinder, gear is installed simultaneously, by it, transmission of power just can be realized to generating to generator.
Its eccentric shaft of bent axle only has one, and needs the eccentric shaft that ensures bent axle towards the opposite direction of base, and two ends are connected on bearing, and eccentric shaft provides articulating point for connecting rod tip.
Its two ends of cylinder are arranged on the two ends of bent axle by bearing, cylinder can freely rotate around crankshaft center line, and gear is installed for power output in cylinder one end, and cylinder is uniform six flutings and six blades formation sliding pair circumferentially.
Blade telescopic variation is to realize like this, bent axle is connected on bearing, and need the eccentric shaft of guarantee bent axle towards the opposite direction of base, cylinder is arranged on the bearing of crankshaft two end, connecting rod tip and bent axle are hinged, the bearing pin of small end and blade is hinged, the circumferential fluting of blade and cylinder forms sliding pair, in the time of water impact blade, because eccentric shaft axis and the cylinder axis of bent axle have certain offset distance, ensure that distance that upper half part blade stretches out cylinder is all the time than the length of lower half portion blade, just make upper half part blade stressed large compared with lower half portion as long as therefore have current or wind to impact blade, thereby producing torque drives cylinder to rotate, cylinder rotates and has just driven conversely the flexible of blade, thereby realize the telescopic variation of blade.
