Abstract
The utility model discloses a technology of a vortex style high performance wind machine, comprising a central rotary shaft, a wind wheel and a generator. The utility model is characterized in that the wind wheel is composed of a fixing disk, and four spiral blades which are in the shape of curved surface bending, the central area of the wind wheel is provided with a rotational flow wind cavity which is used for enhancing wind effect, the wing ends of the blades are provided with a weighting iron, and a central rotary shaft which is connected with one side of the generator is provided with an inertia flywheel which is used for enlarging the wind. The utility model has high flow speed and high efficiency, and can generate dynamic force which is larger than the wind by one half. The utility model can be extensively used for wind power generation and wind water pumping, and the utility model can also be arranged on small vehicles for saving or directly replacing needed energy sources.
Description
The utility model relates to the wind motor technical field, specifically a kind of horizontal shaft type, wind wheel blade be curved surface twist shape, can improve rotating speed and increase the high-efficient wind turbine of power.
The kind of existing wind generating unit is many, and especially in order to make full use of natural wind energy, improve rotating speed, increase power, so, on the wind wheel of wind energy conversion system and blade, done many new improvement.No matter be the improvement of horizontal axis structure, or the improvement of perpendicular axis type structure, purpose all is in order to improve the blowing area of blade as far as possible, to make natural wind promote blade and produce moment, and rotating shaft drives the generator amature rotation and generated electricity.For example, what have takes to increase blades height and width, and the quantity that perhaps increases blade makes full use of wind energy; The angle of passing through automatic adjusting vane and the blowing area that have improve wind energy conversion system making full use of natural wind; Taking on wind energy conversion system of having is provided with wind-force and strengthens mechanism or measures such as wind gathering wall, air channel and improve utilization to wind energy.In a word, the improvement of these structures has been played positive effect for the power and the usefulness that improve wind energy conversion system.
But it is complex structure that said structure improves the outstanding problem that exists, and own wt strengthens.Because the pressure that bearing bore increases, so often can't start operation under the less situation of wind-force.Owing to complex structure, own wt strengthens simultaneously, and thing followed problem is that Applicable scope is restricted, and is difficult to make wind energy conversion system to apply under various conditions.
The purpose of this utility model is exactly to propose a kind of eddy type high-efficient wind turbine that improves vane stress area and wind wheel rotative power at above-mentioned the deficiencies in the prior art.
The purpose of this utility model is achieved in that a kind of eddy type high-efficient wind turbine, same as the prior art is that wind wheel is housed on central rotating shaft, central rotating shaft is provided with bearing bracket stand and connects with motor, it is characterized in that, wind wheel is made up of the fixed tray and the twist vortex type blade of shape of curved surface that is that is installed on the fixed tray, the wind wheel center region is provided with eddy flow wind chamber, the height in wind wheel eddy flow wind chamber and the ratio between the rotor diameter are about 1: 4, it also is 1/2nd of length of blade, be provided with at the wing tip of blade and increase the weight of iron, on the central rotating shaft that connects generator one side, inertial flywheel is installed.
The utility model major advantage compared with prior art:
The one, can increase power.Because pneumatic equipment blades made has made into to be the twist vortex type blade of shape of curved surface by several, the wind wheel center region has been provided with and has strengthened the eddy flow wind chamber of wind-force effect, so improved the lifting surface area of blade and the speed that wind wheel rotates effectively.When natural wind blew wind wheel blade, a part of wind-force directly promoted the blade rotation, passed behind the generation power; Another part wind-force enters the eddy flow wind chamber of wind wheel when promoting the blade rotation, and carries out the rotate-stationary mode of 360 degree, produces secondary power with this.Especially wind-force constantly passes in and out the eddy flow wind chamber of wind wheel in the process that promotes the blade rotation, owing to prolonged the move distance of wind, increased the run duration of wind, pressure in the eddy flow wind chamber of wind wheel is increased, and flow velocity is accelerated, thereby can produce greater than the power of wind-force more than one times.On probation facts have proved can produce the electric power about 100 watts when wind speed is 1 meter per second.When being 4 meter per seconds, wind speed can produce the electric power about 500 watts.
The 2nd, the purposes of this wind energy conversion system is wider, except can be used for wind-power electricity generation, outside the wind-driven water pumping etc., can also be installed on the small-sized traffic tool, saves the energy or directly substitutes the needed energy.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model wind wheel and blade;
Fig. 3 is the fixed tray structural representation of fixing wind wheel and blade.
As shown in Figure 1, 2, this eddy type high-efficient wind turbine is a kind of wind motor of horizontal shaft type, comprises central rotating shaft 4, wind wheel 1, bearing bracket stand 3 and generator 6, wind wheel 1 is installed in an end, the other end of central rotating shaft 4 and generator 6 connections of central rotating shaft 4 by fixed block.Wind wheel 1 is by fixed tray 2 and be installed on the fixed tray 2 four and be the twist vortex type blade 9 of shape of curved surface and form, and wind wheel 1 center region is provided with the eddy flow wind chamber 7 that strengthens the wind-force effect.The diameter of wind wheel 1 is 280cm, and the length of blade 9 is 140cm, and about the about 70cm of height in the eddy flow wind chamber 7 of wind wheel 1 center region, the optimal proportion between the height in eddy flow wind chamber 7 and wind wheel 1 diameter is 1: 4, just 1/2nd of blade 9 length.Be provided with one at the wing tip of each blade 9 and increase the weight of iron 8, the inertial flywheel 5 that increases wind energy conversion system power is installed on the central rotating shaft 4 that connects generator 6 one sides.
