Abstract

A bionic pneumatic machine includes a wind tower, a horizontal shaft, a radiation shaft, a wind blade, a retainer, a shell, a wind vane and a fastening nut. Both ends of the shell of the horizontal shaft on the wind tower is mechanically provided with three to four radiation shafts of same length extending all sides in the equidistant position, and each radiation shaft is provided with the wind blade of equal spacing, same number and specification. The surface of the wind blade is an irregular net structure imitating the shape and size of wings of dragonflies, butterflies and other insects; the surface distributed with cilia can also be a feathered structure like bird wings. The blade surface positively stressed can open and close according to the wind direction, thus acquiring a pneumatic machine with a strong wind-catching capacity. The utility model has the characteristics of more than 95 percents wind-catching capacity, stable operation, high utilization rate of wind power and small interference between pneumatic machines. In addition, one pneumatic machine wind tower can be provided with a plurality of pneumatic machines and one wind field can be provided with a plurality of pneumatic machines, thus reducing the weight of wind blade and decreasing the activated wind speed of pneumatic machine.

Description

Bionic windmill

Technical field

Originally be that model utility provides a kind of resistance, low cost, bionic windmill of supporting.

Background technique

Wind-power electricity generation is a product ripe relatively in world today's scope, and the efficient wind generator of bionic type is that wind energy conversion system and the structure division at existing wind power plant improves, overcomes existing wind energy conversion system and catch the new technology that shortcomings such as wind energy power low (only 27%) and phase mutual interference, unit cost height propose.

Summary of the invention

The present invention seeks to provide a kind of bionic windmill of catching wind efficient to resistance, low cost, height.

The present invention realizes in the following way

Bionic windmill is to improve a new technology of proposition at the wind energy conversion system and the structure division that have wind energy conversion system equipment now.Its structure is made up of wind tower 1, transverse axis 2, radiation axle 3, fan blade 4, snubber 5, shell 6, weathercock 7 locking nuts 8.Three-four radiation axles 4 that stretch out equal length to the four sides are fixed with the method for machinery respectively in the position of two ends five equilibrium on the shell 6 of a transverse axis 3 of wind tower 1, fixing fan blade 4 on each bar radiation axle 4 with equidistant, equivalent amount, equal specification, fan blade 4 can rotate around the radiation axle, fan blade 4 blade faces are that the front is subjected to wind-force, and the slewing area of fan blade 4 is controlled at single blades 4 and radiation axle 3 and begins to rotate in 90 ° of-105 ° of circular arc scopes from vertical.Fan blade 4 is the irregular arc surface shapes of a plurality of big or small convex-concaves for imitating expanded letter network 9 structures of insect such as dragonfly Yan, butterfly's wing shape in the network 9.What have during fan blade 4 rotation opens the pressure that wind is accepted on front or inclined-plane, and what have closes up the resistance that wind is accepted at the back side.Can launch or close according to the fan blade face on the wind-engaging force direction fan blade 4 simultaneously, so just can obtain the strong wind energy conversion system of the wind energy power of catching that to control.

The characteristics of this bionic windmill structure: the one, the arc surface in the network has increased fan blade 4 lifting surface areas, the wind energy power of catching than same level area has improved, its two each network lattice are a wind-engaging unit, wind-force forms turbulent flow in the unit, rotate in disorder, influence each other, just having upset whole wind-force among a small circle flows to, give birth to the formation turbulent flow on the blade face, reduce the vibrations that the slip of wind on the blade face produces, improved the stationarity of fan operation, avoided the uncontrollable situation of the excessive blower fan of wind-force, network shape structure reduces fan blade 4 quality under the same thickness situation, and intensity is constant.This similarly is the insect that circles in the air such as the wing of dragonfly Yan, is that shielding wire is formed class square body one by one through observing the special point of dragonfly Yan wing by train of thought, finned surface in the class square body is the flexible face body, and the finned surface of dragonfly Yan flexible face body is ultra-thin, wind one blow in the train of thought flexible body towards on heave, can form arc surface shape one by one, increase than the surface area of plane, catching wind energy power increases naturally, and owing to arc surface corporeity one by one, make wind on finned surface, form a plurality of irregular turbulent flows, turbulent flow makes change of the wind, the phase mutual interference, and flow velocity reduces, form air cushion, this just makes dragonfly only depend on the air-flow upwards health that can steadily suspend under the condition of calm or gentle breeze.Its three fan blade 4 owing to design is direction rotations from top to bottom, to laterally and the top wind field disturb little, disturb little between the wind energy conversion system, special construction on the while fan blade 4, the wind that makes Sliding velocity on the blade face reduces, wind field area of influence is on every side dwindled, be convenient to same wind energy conversion system wind tower many wind energy conversion systems are installed up and down, more multi-section wind energy conversion system is installed in the same wind field.Its four flying bird can circle in the air under the condition of calm or gentle breeze on high, and the wind energy power of catching of the wing of flying bird is necessarily very strong, and the feather of the wing through observing flying bird is made up of the many vibrissas in both sides, vibrissa is again a feather under magnifying glass, thin vibrissa is stretched out in the feather both sides, and a side vibrissa is swung to the side to the tip, opposite side vibrissa barb curved shape, like this, several rows of thin vibrissa becomes network state by mixed and disorderly the linking together of barb vibrissa, and wind catching area increases, increase is caught wind energy power height to the resistance of wind.

The invention has the beneficial effects as follows

One, be to catch wind energy power can surpass 95%, it is doubly many to improve 2-3 than present wind-driven vehicle.Two, the wind-driven vehicle traveling comfort is good.Be that the utilization ratio of wind energy is improved three,, a wind energy conversion system wind tower can be installed many wind energy conversion systems up and down, and more multi-section wind-driven generator is installed in the same wind field.Four, be that the fan blade quality alleviates, the intensity height.Five, be the startup wind speed that can reduce blower fan, start wind energy conversion system, reduce to 2-3 level wind-force and promptly turn by original 4-5 level.
