Abstract

The invention discloses a windmill, the vanes of which can be opened and closed automatically. The vanes and the heart piece of the windmill are a relatively independent whole body. The vanes are fixed at the radial rib plate of the heart piece by a gemel and can be turned considering the gemel as a rotating shaft. The turning direction and the turning angle are controlled by a cam mechanism which is fixed between two vanes which are symmetrical from up to down in one set. The cam mechanism is controlled by a cam curve groove which is fixed at a windmill upright post. The vanes rotate at the heat piece as a carrier along with the heat piece and also are opened and closed regularly under the manipulation of the cam mechanism at the same time. When the windmill is placed and is installed, the cam curve groove fixed at the upright post is processed for circle direction adjusting and positioning according to the local wind direction, which can realize that each set of vanes are opened at a downwind side to push the heart piece to rotate by the wind power resource and are closed at an upwind side to eliminate the counteracting action towards the heart piece caused by the counterforce of the upwind side, which transforms the wind power into mechanical energy at the maximum. The open degree of the vanes of the windmill can be controlled automatically according to the local wind power, and the operation process is very safe.

Description

Automatic blade opening and closing type windmill

Affiliated technical field

The present invention relates to a kind of wind mill equipment, especially its blade can open and close automatically and adjust automatically according to local wind-force size the windmill of blade opening.

Background technique

At present, known windmill is made up of on a rotatable heart wheel some fixing blade installation, does the time spent when blade is subjected to wind-force, along the wind direction rotation, and then drives the rotation of heart wheel.But, the blade of this windmill is in rotary course, one playing a driving role in the face of heart wheel with the wind, simultaneously again the heart is being taken turns inhibition against the wind, the proportion of goods damageds of wind resource are increased, caused wind energy low, in addition the conversion efficiency of mechanical energy, the blade opening of this windmill can not be controlled, and is subjected to powerful action of centrifugal force in big and flies out easily and cause the accident running into wind-force.

Summary of the invention

In order to overcome inefficiency that existing windmill exists and the deficiency that exists at secure context, the utility model provides a kind of automatic blade opening and closing type windmill, and this windmill is the efficient height not only, and the aperture of blade can control automatically, and is as safe as a house in running.

The technical solution adopted for the present invention to solve the technical problems 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 windmill 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 windmill, 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 impeller rotation, reached effectively utilize wind resource and purpose of safe operation.

The invention has the beneficial effects as follows

Can utilize wind resource to greatest extent, improve wind energy the conversion efficiency of mechanical energy and the safety coefficient of operation.

Description of drawings

The present invention will be further described below in conjunction with drawings and Examples.

Fig. 1 is an embodiments of the invention longitudinal section tectonic maps.

Fig. 2 is an External view of the present invention.

Among the figure

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

Embodiment

In Fig. 1, heart wheel (1) is fixed together by the top external circumference of bearing and column (6), 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 transfer out, 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.

Claims

1. novel windmill, promote blade by wind-force, drive heart wheel, and then drive heart wheel rotation, it is characterized in that: blade one end is connected with the hinge that the heart is taken turns on the gusset, another section by follow heart wheel together the cam mechanism of rotation is connected with cam curve groove on being fixed on millpost, blade can open and close automatically in running, can be according to the aperture of the automatic adjustment of wind-force size blade.

2. windmill according to claim 1 is characterized in that: blade and heart wheel are a relatively independent integral body, and the two rotates synchronously, and blade is connected on the radially gusset of heart wheel by hinge, can be that rotating shaft is overturn with the hinge.

3. windmill according to claim 1 is characterized in that: blade is a carrier in rotation with heart wheel, controls its automatic opening and closing by cam mechanism, and can adjust the aperture size of blade automatically according to the size of local wind-force.
