Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, the present invention is a kind of vane telescopic tidal current energy power generation, including the hydraulic turbine, electromotor 5, kuppe 1, frame 9 and buoyancy aid 10, the described hydraulic turbine and electromotor 5 are fixed in frame 9, frame 9 is connected with buoyancy aid 10, described buoyancy aid 10 is anchored by anchor cable 11, and described kuppe 1 has arc-shaped curved surface 1a and two faces of inclined-plane 1b.
More than 4 sheet blades 2 constitute impeller in being uniformly embedded into impeller hub 3;Blade 2 uses arcuate structure, and blade 2 one end is embedded in slide rail 4 by connecting element, and connecting element can be a projection, it is also possible to be assembly or other structures can fixed in slide rail 4 and move freely along slide rail 4 of bolt and nut;As shown in Figure 1 and Figure 4, slide rail 4 is arranged in impeller two ends, and slide rail 4 is elliptical shape;The blade 2 control action by slide rail 4, gradually stretches out on the upside of wheel hub 3, gradually tapers up in wheel hub 3 in downside.
Slide rail 4 is in addition to ellipse, can also is that other are variously-shaped, such as circular or slide rail be shaped upper part be that parabola shaped bottom is circular or slide rail top is that rounded lower portion is parabola shaped or slide rail top is that parabola shaped bottom is oval or slide rail top is that ellipsoidal lower part is parabola shaped or hyperbola and their combination and any blade that contributes to quickly stretch out in side, at the special-shaped curve of the quick indentation of opposite side.
No matter but which kind of shape, should ensure that slide rail 4 must be made up of a complete arc or be formed by connecting by multistage arc a coherent entirety, the center of whole slide rail 4 is on hub axis top, to ensure that blade 2 stretches.
As it is shown in figure 1, impeller two ends are fixed in frame 9;Kuppe 1 is fixed in frame 9, and side is arc-shaped curved surface 1a, and opposite side is inclined-plane 1b, and the tidal current speed flowing through blade 2 protruding side increases.
Fig. 1 is that apparatus of the present invention structure constitutes schematic diagram, and capacitation device entirety uses horizontal shaft type structure, and its rotary shaft is vertical with direction of tide.
As in figure 2 it is shown, blade 2 stretches out on the upside of impeller, trend active force suffered by blade 2 concave surface drives wheel rotation.During wheel rotation, on the upside of impeller, blade 2 forwards on the downside of impeller, and slide rail 4 makes blade 2 gradually taper up to wheel hub 3, and blade 2 is not by trend effect;Impeller bottommost blade 2 forwards on the upside of impeller, stretches out acquisition driving force under slide rail 4 acts on.Wheel rotation makes blade 2 the most flexible, and impeller unilateral stress all the time, under identical tidal current speed, suffered rotating torque is maximum.When the flow direction changes, by the Accommodation of buoyancy aid 10, making capacitation device automatic direction regulating, flowing side is still arc-shaped curved surface 1a, thus realizes convection current.In embodiment as shown in Figure 1, hydraulic turbine output shaft 8 side (left side in figure) is provided with electromotor 5, and electromotor is connected with shaft coupling 6 and speed increaser 7;As the case may be, impeller rotary motion directly drives electromotor 5 to generate electricity by shaft coupling 6 or drives electromotor 5 to generate electricity after speed increaser 7 speedup.
When (in figure arrow be oriented to trend flow to) flows through kuppe 1 as in figure 2 it is shown, flow, the blade 2 stretched out on the upside of kuppe arc-shaped curved surface 1a stream guide vane wheel in the future, stretches out the tidal current speed of blade 2 increase so that flowing through.
Fig. 3 is that buoyancy aid self adaptation flows to functional schematic.As shown in Figure 3, buoyancy aid 10 is that bipyramid head is columnar structured, cylinder both sides are provided with the wing structure of oval cross section, cylinder one end anchor cable 11 cut with scissors with cylinder anchors, make it do 360 ° of rotations around anchor point in sea level, and the non-anchor fixed end (front end) of cylinder points to the flow direction (in figure, arrow is oriented to the trend flow direction) of trend all the time.When trend flows to change, it is adjusted correspondingly by the effect buoyancy aid of trend, makes buoyancy aid 10 flow to trend the most all the time keep consistent, thus ensure that device all can realize convection current when trend deflection is even swung to.
Although the detailed description of the invention of the present invention is described by the above-mentioned accompanying drawing that combines; but not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical solution of the present invention, those skilled in the art need not pay creative work can make various amendment or deformation still within protection scope of the present invention.
