Description
Technical field
The present invention relates to a kind of electricity generating device.Specifically, be the entrained kinetic transformation of current (particularly ocean current) can be become mechanical energy, and export to the water turbine that generator carries out ocean current power generation.
Background technique
As everyone knows, the area of earth surface more than 70% covered by ocean, and under the promotion of wind-force and other power, seawater is following moving that certain route goes round and begins again all the year round, this has just formed ocean current, the scale of ocean current will be far longer than the river in the rivers and lakes of land, and it is a kind of inexhaustible, nexhaustible environmental protection resource.
In the last few years, in order to reduce the transition development and utilization of earth energy, countries in the world were all relatively paid attention to utilizing the environmental protection resource to generate electricity, and this wherein just comprises ocean current power generation.Traditional ocean current power generation system, its structure and principle are all similar with wind-power generating system, namely on the stream of ocean current, impeller are set, and wherein main a kind of impeller is vertical axis impeller, and namely the stream of the rotating shaft of its impeller and ocean current is perpendicular.During use, vertical axis impeller is immersed in seawater fully, the blade and the rotating shaft that utilize ocean current to promote vertical axis impeller are rotated, and the mechanical energy of rotating are exported to generator generate electricity.But, when vertical axis impeller rotates, when its blade turns to lee side from fluoran stream surface, the back side of blade can be subject to the impact of ocean current equally, this impact can hinder the rotation of blade, and then the rotation of countershaft generation obstruction, the loss that this has just caused ocean current kinetic energy makes power generation system lower to the utilization ratio of ocean current kinetic energy.China is among the people has just invented a kind of waterwheel a long time ago, it is that frame supported with a circle is at the water surface, and in the outer of circular frame, bucket is set, the Main Function of this waterwheel is to provide the required power of daily life and water for the mankind, also can be Plants irrigation water is provided, it only can be arranged on the surface in river, and the kinetic energy of top layer current is utilized, be unsuitable for underwater power generation, thereby can't directly use in the ocean current power generation field.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of ocean current power generation water turbine, adopts this water turbine to carry out ocean current power generation, and is higher to the utilization ratio of ocean current kinetic energy.
For addressing the above problem, take following scheme:
Ocean current power generation of the present invention is to comprise cylindrical case with the characteristics of water turbine, and cylindrical case is closed shape, and all there is through hole its central position, two ends, and rotating shaft is arranged in through hole.That section rotating shaft periphery in described cylindrical case is evenly equipped with blade radially, all is connected by radial struts between blade and rotating shaft.There is the ocean current pipeline described cylindrical case below, the ocean current pipeline is lateral arrangement, the cylindrical case downside is processed with the opening that connects its length, on ocean current pipeline upper wall, opening is arranged, be between the opening surrounding of cylindrical case and the opening surrounding of ocean current pipeline and be sealedly and fixedly connected, make described blade pass cross this opening and stretch in the ocean current pipeline and described rotating shaft and ocean current pipeline vertically perpendicular.
The further improvement of the present invention scheme is that described blade is formed by connecting by a multi-disc watt shape plate, and the corresponding straight flange of adjacent two watts of shape plates links together.The design of watt shape plate can improve blade to the support of ocean current, reduces ocean current along the diffusion of blade surrounding, further improves the utilization ratio of ocean current kinetic energy.
The further improvement of the present invention scheme is that the outer of described blade has the cylindrical bridge, and plane and the rotating shaft at cylindrical bridge place are perpendicular, and all is between blade and cylindrical bridge and is fixedly connected with.Utilize the cylindrical bridge to reinforce blade, make blade axially remain equidistantly along rotating shaft, bias can not occur during rotation, guarantee that hydraulic turbine operation is smooth and easy.
The further improvement of the present invention scheme is that the inner circle bridge is arranged on described radial struts, and plane and the rotating shaft at inner circle bridge place are perpendicular, and all is between radial struts and inner circle bridge and is fixedly connected with.Utilize the inner circle bridge to reinforce support radially, the stress of alleviating single radial struts and rotating shaft joint is concentrated, and makes hydraulic turbine structure more stable, increases its working life.
Further improvement project of the present invention is that described cylindrical case comprises the upper and lower, and the upper and lower part is semi-cylindrical shaped, and all there is horizontal outer convex rib both joints, and the outer convex rib of upper and lower part is fixed together by screw bolt and nut.Like this, when needs are maintained water turbine inside, only need screw bolt and nut is removed, and the top of taking off cylindrical case gets final product.
Take such scheme, have the following advantages:
The cylindrical case of sealing is arranged with water turbine due to ocean current power generation of the present invention, and the cylindrical case downside is connected with the ocean current pipeline, ocean current is when flowing through water turbine, can be by the scope of this ocean current pipeline restriction ocean current impact blade, be ocean current all the time at the inner chamber lower impact blade of cylindrical case, during to lee side, its back side can not be subject to the impact of ocean current when blade rotation, the rotation of blade and rotating shaft can not hindered, thereby can improve the utilization ratio of ocean current kinetic energy.
