Description
Technical field
The utility model relates to wind energy power field, specifically a kind of vertical axis wind power generation structure.
Background technique
The generation of wind is because the air of the sun by earth's surface is heated, and air heats expands and to lighten and toward rising, after hot air rises, in low temperature, air is just from surrounding laterally inflow, thus forms the flowing of air, Here it is wind.The blast that wind-power electricity generation produces when being and being flowed by air, by the Aerodynamic force action (comprising lift and resistance) of air, promote the blade rotary of wind energy conversion system, and then drive electrical generators rotates and then converts electric energy to.Although wind-driven generator is varied, is summed up and can be divided into two classes: 1. horizontal axis wind-driven generator, the running shaft of wind wheel is parallel with wind direction; 2. vertical axis aerogenerator, the rotational axis vertical of wind wheel is in the direction of ground or air-flow.
Horizontal axis wind-driven generator is made up of parts such as fan blade, gearbox, accelerating gearbox, generator, offset assembly, control system, pylons.The effect of fan blade is mechanical energy by Wind resource change, and it is contained on wheel shaft by the blade that gas flow capability is good and forms, and the fan blade slowly run carrys out speedup by transmission system via accelerating gearbox, by conducting power to generator.These assemblies above-mentioned are all arranged in cabin, whole cabin is supported by tall and big pylon, because wind direction can often change, in order to effectively utilize wind energy, the device of automatic wind facing must be had, according to the wind direction signals that wind direction sensing instrument records, excursion motor is controlled again by controller, driving pinion goes to promote the gearwheel on pylon, and the system that whole cabin is controlled automatically by this, keeps correct windward side.
The dynamo bearing of horizontal blower fan is parallel to wind direction, also just represent that its blade is vertical with wind direction, so adopt lift-type blade, can than the larger wind energy of push type blade acquisition of vertical shaft fan, therefore horizontal wind power generator just must rotate to chase wind direction by energy 360 degree.Its blade shape has single leaf, double leaf, three leaves and four leaves.The rotating speed of single leaf and double leaf is usually very fast, and gear ratio is lower, but the variation of blade in lower regions is comparatively large, easily derivative fatigue loading, and dynamic vision, blade balance and delivery efficiency are poor.Although four leaf delivery efficiencies are the highest, cost viewpoint is still with Three-blade best, therefore the horizontal blower fan of Three-blade form is the most common current machine.Another with its rotor seat to being divided into again windward type and two kinds, leeward type.
The great advantage of horizontal blower fan is that delivery efficiency is high, but shortcoming to be wind sweeping area (the dynamic 360 degree of planimetric areas of blade) large, cost and maintenance expenses is high and noise is large.
The plurality of advantages such as vertical axis aerogenerator has need not to wind direction, noise free, and Security is high are important directions of following wind-driven generator development.Existing vertical axis aerogenerator is generally all made up of critical components such as blade, transmission system, generators, is input on the main shaft of generator, drive electrical generators main axis by transmission system by the torque on blade of wind-driven generator, and then generating.The efficiency of whole generator system is not high, and the structure of complete machine is also compact not.
Application number be 2014102026684 patent of invention disclose a kind of vertical axis aerogenerator, comprise supporting frame, be arranged on the central shaft on supporting frame, wind wheel is on center shaft installed, in wind wheel is, the double layer construction that outer leafs is nested, and be that the center of circle is arranged with one heart with central shaft, intra vane is placed in the center cavity that outer leafs surrounds, intra vane is lift-type, outer leafs is resistance type, intra vane is connected with central shaft by free wheel device, intra vane is provided with coil, outer leafs is fixed with permanent magnet, in, outer leafs relatively rotates along contrary direction around central shaft.This vertical shaft wind power generator structure is complicated, need the inside and outside blade double layer construction of direction of rotation to improve generator efficiency, while cost is high, in order to prevent inside and outside blade generation rotating in same direction in wind-driven generator running, connect intra vane and central shaft with free wheel device, intra vane can only one-way rotation when normal work to ensure wind-driven generator.During in order to prevent wind speed higher than design wind speed, wind-driven generator is destroyed, and also needs to arrange magnetic clutch and speed probe in addition.
