Abstract
The utility model relates to a vertical axis aerogenerator indicates neotype vertical axis symmetry formula aerogenerator's blade and wind wheel especially. The blade be that a cross -section is convex unsmooth simple blade, blade edge circumferencial direction card is in the draw -in groove of vertical axis 6, and the concave surface of blade installs towards the vertical axis, adopt 4 blades, constitute two S type aerogenerator. Go up the chuck 1 and the convex recess of facing (operation) of chuck 3 down, the both ends card makes vertical axis, upper and lower chuck and blade form a whole in these recesses about during rooting -in of blades, constitutes the wind wheel. Upper and lower chuck passes through the fix with screw and on the vertical axis, prevents that chuck and vertical axis from having relative rotation. Its characteristics lie in: the blade simple structure, simple to operate, and install along vertical axis circumferencial direction symmetry, during operation stability is high, wind wheel compact structure, small friction, low wind speed easily starts down, the design of two S types is convenient for full aspect and is received and the wind comes from, improves wind energy utilization and rates.
Description
Technical field
This utility model relates to vertical axis wind power generation technical field, the blade of a kind of novel wind-driven generator being symmetrically installed along vertical axis circumferencial direction and wind wheel, stability and reliability that wind-driven generator runs can be improved, it is easy to start under low wind speed, improve wind energy utilization.
Background technology
In order to preferably utilize wind energy, people devise the wind power generation plant of a variety of version for a long time.The rotary shaft of the foundation wind-driven generator difference in direction in space position, wind-driven generator is divided into the horizontal axis wind-driven generator of horizontal direction and the vertical axis aerogenerator of vertical direction by people.
The flabellum of horizontal axis wind-driven generator is similar to Holland's windmill, and complex-shaped, difficulty of processing is high.Blade wind-engaging produces mechanical energy only with lift when rotating.Blade be the wind comes from only with one direction, it is necessary to installing expensive yaw device and realize fan blade to wind, for once cut-off wind chance, tower shadow effect is the biggest with pneumatic shear effect simultaneously.And the blade shape of vertical axis aerogenerator is varied, but on the whole, it is all basic geometry, it is easy to processing.Blade can be the wind comes from comprehensive acceptance, it is not necessary to yaw device.Can repeatedly cut-off wind, make full use of wind energy.During operation, horizontal axis wind-driven generator aerodynamic noise is big, and blade is cut lotus by alternation, and fatiguability deforms.Vertical axis aerogenerator does not the most produce aerodynamic noise, blade by constant section of lotus, durable be difficult to impaired.The dynamo cradle of horizontal axis wind-driven generator is located at high-altitude simultaneously, and the cost of installation and maintenance is the highest, and fan blade regularly to clean, to ensure to run well under high wind speed；The electromotor of vertical axis windmill is positioned at lower even ground, it is simple to installs and keeps in repair, adaptable to adverse circumstances of fan blade.More than comparing and be not difficult to find out, vertical axis aerogenerator all shows outstanding in all many-sides, becomes the dominant direction of following wind driven generators.
This utility model uses the concavo-convex blade of symmetrical expression circular arc to constitute double S type wind wheel according to vertical axis aerogenerator so that it is can have high wind energy utilization while low wind speed self-starting.
Utility model content
The purpose of this utility model is to provide a kind of Novel wind power generator blade and wind wheel, uses vertical axis formula blade of wind-driven generator and wind wheel, optimizes blade configuration and changes the installation method of blade, improving the utilization rate of wind energy.
In order to reach above target, technical solutions of the utility model are: this blade of wind-driven generator and wind wheel, mainly include base, vertical axis, blade, upper chuck and lower chuck, it is characterized in that: described vane airfoil profile is the concavo-convex simple configuration of circular arc, 4 blades are along the circumferential direction symmetrically installed on the vertical axis in double S-shaped, two ends are stuck in the draw-in groove of upper and lower chuck simultaneously, and the concave surface of blade is installed towards vertical axis.Upper chuck, lower chuck, add the area of section of blade, improve the effect of going for a drive of blade while increasing firmly installing property of blade.Blade and vertical axis, upper and lower scroll chuck form an entirety composition wind wheel, improve the stability that blade rotates.Flabellum uses 4 blades, installs relative to vertical axis, constitutes double S type wind-driven generator, it is simple to receive the wind comes from from all directions, it is easy to start at low wind speeds, thus improve the utilization rate of wind energy.

Detailed description of the invention
Along the circumferential direction being arranged in the groove 8 of vertical axis 6 with axisymmetric form by the 4 of fan blade of wind driven generator blades 2, upper/lower terminal is separately mounted to upper chuck 1 and composition wind wheel (Fig. 6) in the groove 8 of lower chuck 3.The concave surface of blade 2 is installed towards vertical axis, and upper and lower chuck connects blade and vertical axis 6 respectively to increase the stability of wind wheel.
Utilizing S type wind wheel the most still to have the advantage of bigger detent torque, stacked together by the S type fan blade at 90 ° of angles of two groups of mutual deviations vertical axis 6 altogether, often group blade 2 is made up of two arc cylindrical blades.The design of two group of four blade ensures the abundant collection of different wind direction, and in the case of the non-pooled wind direction of low wind speed, double S type fan blades can start rapidly, and higher to the utilization rate of wind energy under high wind speed.This utility model preferably solves low wind speed and does not start the problem the highest to the utilization rate of wind energy with high wind speed.
Selecting 4 blades 2 to can obviously reduce the impact of torque ripple and balance is preferable, each blade 2 is concavo-convex simple vane configuration.Blade profile is constant, the most non-warping, and simple shape can be mass, and reduces cost.
