Abstract

The utility model relates to an aero-generator, vanes of which can be opened and closed automatically. The vanes and a heart piece of the aero-generator are relatively independent whole bodies; the vanes are fixed on a radial reinforcing plate of the heart piece through a hinge and can overturn by taking the hinge as a rotating shaft; overturn direction and angle are controlled by a cam mechanism between two vanes which are symmetrically fixed up and down in the same group; the cam mechanism is controlled by a cam curve groove which is fixed on an upright post of the aero-generator; on a carrier that is the heart piece, the vanes act the rotary motion along with the heart piece on one hand, and are regularly opened and closed under the operation of the cam mechanism on the other hand; when in emplacement and installation, the aero-generator adjusts and locates the cam curve groove fixed on the upright post along the circumferential direction according to the local wind direction, thereby realizing that the side towards the tail wind direction is opened in each group of the vanes, the heart piece is pushed to rotate by utilizing the wind power resource, and the side towards the dead wind direction is closed; so the hindering effect to the rotation of the heart piece caused by the reaction force of a dead wind side is eliminated, and the wind power resource is utilized to the utmost extent; the aero-generator can automatically control the opening degree of the vanes in an intelligent manner according to the degree of the wind power, and is very safe during the operation process. A tinfoil region on the surface of the aero-generator can be used for solar electrical energy generation in a windless sunny day or a weak-wind sunny day.

Description

Novel wind generator

Affiliated technical field

The utility model relates to a kind of wind generating unit, and especially its blade can automatic on-off and can be adjusted the wind-driven generator of blade opening according to the wind-force size automatically; One deck " tinfoil paper " zone is equipped with on its surface, at the fine day of calm or weak wind, can utilize solar electrical energy generation.

Background technique

At present, known wind-driven generator is installed on the rotatable heart wheel by some stator blades and forms.When being subjected to wind-force, blade does the time spent, rotate along wind direction, and then drive heart wheel and the generator that is connected on the heart wheel shaft produces electric energy, still, the blade of this wind-driven generator is in rotary course, one playing a driving role in the face of heart wheel with the wind, simultaneously again the heart is taken turns inhibition against the wind, the utilization ratio of wind resource is reduced, causing generating efficiency low, if run into calm or weak wind weather, this wind-driven generator just can't generate electricity.In addition, the blade of this wind-driven generator only depends on heart wheel fixing, and the outer ring is without any other mechanism, and blade can not be along with the size of wind-force be adjusted aperture in operation process, is subjected to the high wind effect and produces huge centrifugal force and fly out easily and cause the accident.

Summary of the invention

In order to overcome deficiency low and that exist at secure context at the bottom of the generating efficiency that existing wind-driven generator exists, the utility model provides a kind of novel wind generator, the blade of this generator can open and close automatically, can be according to wind-force size intelligent control blade opening size, can utilize solar electrical energy generation at calm fine day, the generating efficiency height, as safe as a house in running.The technological scheme that its technical problem that solves the utility model adopts is

The position of turning round in the effect of wind-engaging power, heart wheel and blade are done as a whole the design, heart wheel is by inner ring, the outer ring is formed with the radially gusset that is connected Internal and external cycle, blade is between two adjacent gussets, fix on hinges fixing on the gusset of a side, be positioned at the scope of inner ring and outer ring, can overturn along hinge, heart wheel is the ellipse spheroid, blade divides the upper and lower surface symmetry arrangement, top and bottom have 8 groups of (16) blades, on the generator center stand column, be fixed with the cam curve groove, in the impeller inner space cam mechanism arranged, in operation process, cam mechanism rotates with impeller on one side, per 1 group of blade is clocklike opened or is closed in the effect that is subjected to column overhead cam curved grooves on one side, when the installation in place of this wind-driven generator, as long as adjust the direction that is fixed on column overhead cam curved grooves according to local wind direction, in operation process, will there be 4 groups of blades down the wind to open all the time, and the rotation of the effect of wind-engaging power and impeller; And close all the time against 4 groups of blades of wind direction, avoided wind-force its reaction to be hindered the rotation of heart wheel, reached and effectively utilized wind resource; The blade of this generator is intelligent in addition controls, and can adjust the aperture size of blade according to the wind-force of locality automatically, and under the situation of high wind, blade opening diminishes automatically, makes operation very safe; At the weather that runs into calm or weak wind, solar electrical energy generation is carried out in " tinfoil paper " zone that is beneficial to the surface.

The beneficial effects of the utility model are

Can utilize wind resource to greatest extent, operation is intelligent, hommization, has improved the safety coefficient of generating efficiency and operation.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is an embodiment of the present utility model longitudinal section tectonic maps.

Fig. 2 is an External view of the present utility model.

Among the figure

1. the heart is taken turns; 2. blade; 3. cam mechanism; 4. cam curve groove; 5. driving mechanism; 6. power facility; 7. column;

Embodiment

In Fig. 1, heart wheel (1) is fixed together by the top external circumference of bearing and column (7), and blade (2) links to each other by the radially gusset of hinge with heart wheel (1); One end of cam mechanism (3) links to each other with blade (2), and the other end links to each other with cam curve groove (4) on being fixed on column.The central shaft lower end gear of heart wheel (1) and the upper end gear engagement of driving mechanism (5) will rotatablely move and pass to power facility (6), in operation process, 4 groups of blades (2) are by the control of cam mechanism when running to the wind one side, with the hinge is that the automatic upset of rotating shaft is opened, these 4 groups of blades (2) are that the automatic upset of rotating shaft is closed by the control of cam mechanism with the hinge when running to the contrary wind one side; And the like, go round and begin again.
