Description
Technical field
The present invention relates to a kind of fluid impact type generator, relate in particular to a kind of supporting structure of generator amature.
Background technique
The environmental problem that the use of non-renewable energy resources brings is serious day by day, and clean reproducible energy more and more receives countries in the world and payes attention to, and wind energy and trend can especially become the focus of development and use renewable energy sources.In wind energy and the trend ability one-level transducing head; Flexible blade rotor is as a kind of brand-new capacitation device; Have advantages such as capacitation efficient is high, the application flow rates is wide, cost is low, the cavitation corrosion phenomenon is not obvious; But its supporting structure has in light weight, blade to be prone to requirements such as frictional force is little between replacing, blade and the blade to flexible blade rotor, and it is more that structural design is considered a problem.
The main device that extracts wind energy at present is the rigid blade rotor, and its capacitation coefficient is lower, and it is bigger to start wind speed.Defectives such as blade is processed by rigid materials such as glass fibre reinforced plastics mostly, and blade edge is very thin, also may hurt birds etc. during rotation, and exists noise bigger, and metal is perishable.Like disclosed Chinese patent on May 7th, 2003; Publication number is CN1415852A; It discloses the high-effect windmill of a kind of flexible blades, comprises base, support, central shaft, interior bracing ring, unofficial biography moving-coil, outer fixing circle, drag-line, interior external wind wheel, universal head, though it can alleviate the weight of self; But mentality of designing and common windmill commonly used do not have great difference, can only be on the direction of wind, to rotate.Because fan blade processes for very thin steel plate, thus when work, not only produce very big noise, and also fan blade can corrode, and needs often replacing, increased cost.
Summary of the invention
Technique effect of the present invention can overcome above-mentioned defective, and a kind of flexible blade rotor supporting device is provided, and its light weight, structural strength are big, blade is easy to change, frictional force is little between the blade, makes the flexible blade rotor structure more reasonable.
For realizing above-mentioned purpose; The present invention adopts following technological scheme: it comprises central rotating shaft; Two supporting layers perpendicular to central rotating shaft are set on the central rotating shaft at least, on the same circumference that between the two adjacent supporting layers is the center, at interval fixing rod are set, connect through flexible blade between the adjacent fixing rod with the central rotating shaft; The plane that flexible blade is formed with respect to two fixing rods that are attached thereto can produce concavo-convex deformation, and flexible blade is connected with fixing rod through wear-resistant gasket.
Between flexible blade and the supporting layer wear-resistant gasket is set, fixing rod surface socket Antiwear casing.Whole flexible blade rotor presents regular prism shape, and fixing rod passes the antifriction sleeve pipe, and for increasing flexible blade standing part intensity, the blade exact shape is an isosceles trapezoid, and last bottom is sewn into sleeve shape and is enclosed within on the antifriction sleeve pipe, and wear-resistant gasket is set between blade.
Supporting layer adopts dual mode: 1. supporting layer comprises outer ring, flange plate, spoke, and three parts link to each other through the mode of welding; The outer ring is provided with through hole; Flange plate and central rotating shaft are affixed, and with the supporting layer concentric; Spoke is perpendicular to central rotating shaft and is that the center is with the isometric radially strut of same intervals angle with the central rotating shaft; The two ends of spoke are connected with outer ring, flange plate respectively.2. supporting layer is to be isometric plectane of center radius or regular polygon plate with the central rotating shaft; The supporting layer periphery is provided with through hole.
The antifriction sleeve pipe is processed by big, the ganoid wear-resistant tubing of compressive strength.The antifriction sleeve pipe is sandwiched between the upper and lower supporting layer, has both played and has supported the effect of supporting layer up and down, can reduce again and blade between frictional force.The fixing rod end is processed with screw thread, and the length of fixing rod is greater than the antifriction sleeve pipe, and fixing rod and through hole adopt two kinds of Placements: 1. fixing rod runs through through hole, is fixedly connected with supporting layer through nut; 2. an end of fixing rod runs through behind the through hole and is fixedly connected with supporting layer through nut, and the other end of fixing rod and supporting layer are through being threaded.Through-hole aperture is greater than the fixing rod external diameter, and through-hole aperture is less than the Antiwear casing internal diameter.
Central rotating shaft level or vertically be provided with, central rotating shaft can also improve the anti-twisting property of rotor except the effect of playing the upper and lower supporting layer of support rotor, prevent the flexible blade rotor damage that twists.
When changing blade, relate to the dismounting problem of fixing rod.After nut unloaded, fixing rod is extracted out from the other end, can easily take off the antifriction sleeve pipe this moment; Take down then and damage or shabby flexible blade; After installing new blade, fixed sleeving is put between the upper and lower supporting layer, sleeve pipe and through hole align; Penetrate fixing rod then, the fastening nut or the screw thread of screwing get final product again.Flexible blade is under the fluid force effect; Fixed edge rotates around the antifriction sleeve pipe; Between blade and the blade and the mutual friction mutually between blade and the supporting layer be the key factor that influences leaf longevity, the little wear-resistant gasket of smooth surface friction factor is set in these positions, can effectively improve the life-span of blade.
The present invention can make that the flexible blade rotor structure that novel fluid can obtaining device is lighter, blade is easy to change, leaf longevity improves, structure is more reasonable.
