Abstract

A double-column sailboard type wind turbine relates to the field of wind power generation, overcomes the problem that the existing wind driven generator is low in efficiency, and dramatically raises generator efficiency. The double-column sailboard type wind turbine is technically characterized in that a steel pipe is welded into a circular or equilateral polygon metal wheel rim (2) of frame structure to be a framework of the wind turbine; a plurality of sailboards (3) are fixed on the metal wheel rim (2) to form a huge wind turbine; and two ends of a turbine central shaft extend out and are supported by vertical columns (1) built by reinforced concrete. Compared with the existing three-blade wind-driven generator, the wind turbine is enlarged by tens of times in windage area, with the windage surface far from the center and good wind effect. The utilization rate of wind energy and generator power can be dramatically improved. The wind turbine can drive a generator group consisting of a plurality of generating units.

Description

Twin columns sailboard type wind turbine

Technical field

The present invention relates to wind-driven generator, specially refer to the wind-driven generator turbine.

Technical background

Existing wind-driven generator, catching of wind energy is (being generally three blades) of finishing by several blades, and the wind-receiving face of blade is very little, and it is very limited to obtain wind energy, and most wind energies are not utilized.And be subjected to the restriction of weight and intensity, it is generous relatively that root of blade is done, and the tip is but very narrow.According to mechanics principle, the active force decentre is near more, and the moment of generation is just more little, and the active force decentre is far away more, and the moment of generation is just big more.Therefore, the most effective position of capturing wind energy should be near the deep blade tip, and the width of increase root of blade is invalid.This is the existing low reason place of wind power generator efficiency.In addition, existing wind-driven generator is a kind of cantilever structure by single upright supports, and intensity can be very low.Be subjected to the restriction of strength condition, it is very roomy that blade can not be done, and also can not be designed to other very heavy shape, more impossible bearing owing to increasing the huge axial wind-force that blowing area produces significantly.

Goal of the invention

The invention provides a kind of wind turbine, can increase the effective blowing area of blower fan significantly, thereby significantly improve wind energy utilization, significantly improve generator power.

Summary of the invention

The technical solution used in the present invention is: the metal wheel frame of frame structure that welds a circle or regular polygon is fixed on many plates of lifting a sail on the metal wheel frame as the skeleton of wind turbine.Windsurfing is the quadrilateral profile, and the surface is streamlined bending, or simply is the plane, make with lightweight material, can select glass fibre or carbon fiber composite for use, or select cheap materials such as engineering plastics, timber, bamboo, cloth, ox-hide for use, the sail that its effect is similar on the sailing boat is used for catching wind energy.For increasing the join strength that windsurfing is installed, during the windsurfing moulding, the joint at its edge will connect steel plate or have the metal construction that connects steel plate and be embedded in the windsurfing, connect steel plate and extend, when windsurfing is installed, that the steel plate that extends is fastening with bolt or rivet and metal wheel frame.Perhaps whole steel pipe (or shaped steel) run through being embedded in the windsurfing and stretch out at two ends along the edge of windsurfing, the two ends that will stretch out are fixed on the metal wheel frame, and the steel pipe of being inlayed can be isodiametric or two ends diminish.The metal wheel frame is used for installing and fixing windsurfing, plays the effect of skeleton, and the stero shape of its frame structure makes intensity very high, can bear huge wind-force.The material of making the metal wheel frame can adopt stainless steel, also can select shaped steel for use for weight reduction with the General Structural Steel antirust processing in surface, preferentially adopts steel pipe, and the sectional shape of steel pipe can be circle or rectangle or ellipse.The wheel frame can integral solder, also can be welded into several pieces and be assembled into circle or regular polygon then.The wheel frame is horizontal axis, after various plates of lifting a sail are covered with the wheel frame, just constitutes a huge wind turbine.Because near the regional arm of force the turbine center is shorter, the wind-force action effect is poor, for reducing cost windsurfing can be installed.This wind turbine has set up former and later two columns.The turbine center is the structure that two end axles is stretched out, and the bearing support at two ends is bearing in respectively on separately the column.Two columns preferentially adopt reinforced concrete construction, in order to bear turbine deadweight and huge wind-force.For the area that wind is arranged throughout the year, the very urine that turbine diameter can be done is used in family.For small-sized wind turbine, both can adopt reinforced concrete upright column, also can adopt the steel structure column.For large-scale wind-driven generator, the torsion that this wind turbine produces is huge, can be designed to a turbine and drag the electric power generator group of forming by some generators, all generators were worked simultaneously when wind-force was big, wind-force hour only drives several generator work, maintenance and fault treatment also are convenient in design like this, and when a generator broke down maintenance, remaining generator still can continue generating.

Beneficial effect

The invention has the beneficial effects as follows: this wind turbine removes the nearer zone of distance center can not install windsurfing, all the other zones have been covered with windsurfing, the blowing area of turbine increases tens of times than existing three-vane wind generator, and near the regional blowing area the turbine center is zero, wind-receiving face is away from the center, the action radius of power is big, and the wind-force action effect is good.

Specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present invention being made further detail describes.Shown in accompanying

drawing

1,2, weld the metal wheel frame (2) of the frame structure of a circle with steel pipe.As shown in Figure 5, steel pipe (8) run through being embedded in the windsurfing along the edge of windsurfing (3), two ends are welded with the thin bar in termination (9) the steel pipe two ends are blocked, and prevent that rainwater from flowing into the steel pipe inwall.On the other hand, the diameter of the thin bar in termination (9) forms shoulder less than steel pipe (8), thereby prevents that steel pipe from becoming flexible in windsurfing and string is moving.Steel pipe (8) in windsurfing (3) whole run through, windsurfing is played the effect of skeleton and reinforcement.The two ends (9) of steel pipe (8) extend and are fixed on the metal wheel frame (2).As shown in Figure 2, after various windsurfing (3) is covered with, just formed a huge wind turbine on metal wheel frame (2).As shown in Figure 1, this wind turbine sets up former and later two columns (1), and stretch out at turbine central shaft two ends, and the bearing support at two ends (4) is bearing in respectively on separately the column (1).Two columns (1) build up with reinforced concrete, and one of them column top has Generators (6), and the turbine central shaft arrives transmission of power on the interior power generating equipment of machine room (6) by coupling (5).

Accompanying drawing 5 is another embodiment of the present invention schematic side view, this embodiment and last embodiment's difference, be to have set up oblique rollering steel cable (7) between metal wheel frame (2) and central shaft (10), its effect is the same with oblique rollering steel cable on the cable stayed bridge, can improve the force-bearing situation of metal wheel frame (2).
