Energy will then have more thousands of times.The 71% of earth surface is all ocean, this is a kind of huge energy, while being a kind of again
Clean regenerative resource.The ocean current energy of China is also very abundant, and the theoretical mean power along ocean current is 1.4 hundred million kilowatts.Cause
This, improves the research of ocean current power generation machine generating efficiency, for promoting efficiently using for green resource, especially marine resources to have
Very great meaning.
Power station using ocean currents include mainly wheel blades type, parachute-type and magnetic current formula power generator, wheel blades type ocean current at present
Power generator pushes wheel blade, wheel blade rotation that generator is driven to generate electricity using ocean current；Parachute-type power generation device from sea current is by several
Ten parachute compositions being connected on annular hinge rope；It is strutted by the strength of ocean current along the parachute of current direction, inverse ocean current
The parachute in direction is collapsed by the strength of ocean current, and parachute sequence opening and closing move back and forth, and hinge rope is driven then to drive on ship
Capstan rotates, and capstan drives electrical power generators；For magnetic current formula power generation device from sea current using seawater as working media, allowing has a large amount of ions
Seawater perpendicular through strong magnetic field, obtain electric current.
Wherein, since wheel blades type power station using ocean currents have, structure is more simple and convenient to operate and economic cost is more low
Advantage so that wheel blades type power station using ocean currents are in ocean current power generation using more extensively；But existing wheel blades type ocean current power generation
There is also some defects for device, for example, the blade in present wheel blades type power station using ocean currents is integrally set using monolithic
The thinking of meter so that the generating efficiency of present wheel blades type power station using ocean currents is low so that the profit for the huge energy that ocean current contains
It is low with rate.
Invention content
In view of the above shortcomings of the prior art, the technical problem to be solved by the present invention is to：How providing one kind can carry
High ocean current power generation efficiency is not limited and power station using ocean currents reasonable in design and its power generation side by ocean current flow direction
Method.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is as follows：
The centre position of a kind of power station using ocean currents, including pedestal, the pedestal is vertically installed with central shaft, further includes leaf

It crosses mounting hole and is connect with resetting-mechanism, the lower rotary shaft is mounted in installation slot structure, to realize several blade right angle settings
Vertical blind structure is substantially formed in leaf frame.
In the technical program use vertical axis generation system designs, the present invention in blade wheel structure it is vertical with pedestal so that leaf
The universal capture to ocean current energy may be implemented in wheel construction, substantially increases the generating efficiency of the present apparatus.In the present invention by
Several blades are rotatably mounted in leaf frame to form the blade wheel structure for being substantially in shutter shape, the present invention has broken existing leaf
Wheel is all made of the thinking of global design；Use by being arranged on several resetting-mechanisms and bottom plate that are arranged on upper mounted plate again
In the installation slot structure of limitation blade rotational angle；The configuration of the present invention is simple, can Assembling, when impeller be in stand nature
When under state, it is in completely closed state to control several blades by resetting-mechanism, at this point, when impeller is along the flowing side of ocean current
To when rotation, ocean current pushes the blade being closed completely in impeller, and the thrust suffered by the impeller is maximum at this time, therefore, ocean current band
Movable vane wheel quick rotation, impeller drive generator to generate electricity again；When the impeller is rotated against the flow direction of ocean current, the leaf
Several blades in wheel are fully open, and what formation was parallel with ocean current flow direction between two pieces of adjacent blades crosses the mouth of a river so that should
The resistance that impeller is subject to is minimum, can reduce the loss of impeller kinetic energy, improves generating efficiency；Therefore the ocean current provided in the present invention
Power generator enables blade to be closed automatically under the impetus of ocean current, can be used for receiving by rational blade design
Ocean current energy on horizontal 360-degree direction；So that present invention power generation is not limited by ocean current flow direction, and to ocean current
The utilization ratio of energy is higher than traditional impeller, and therefore, the invention enables generating efficiencies to significantly improve.
Further, the resetting-mechanism includes fixed link, anchor pole and connecting rod, and the fixed link and anchor pole are fixed on solid
Determine on the top surface of block, and the top surface of fixed link is higher than the top surface of anchor pole, the both ends of the connecting rod are rotatably fixed on admittedly respectively
On the top surface of fixed pole and anchor pole, it is fixed with pillar on the side wall of the connecting rod, rotating ball is connected on the other end of pillar.
Resetting-mechanism is the gravity rotor structure that inclines in the present invention, and reasonable design is simple in structure, since rotating ball is by gravity
Effect, therefore, the trend that it is always moved immediately below oriented connecting rod, when hawser does not tense, i.e., when rotating ball does not stress, its meeting
It hangs down at the underface of connecting rod, the present invention utilizes rotating ball blade wheel structure easy to implement affected by gravity in the nature of standing
Under state, several blades are in the state being closed completely, and are ensured that in this way when the present invention starts in the early stage by ocean current maximum
Thrust, realize ocean current power generation machine self-starting function, it is whole under static condition to ensure that the thrust in ocean current can drive
A turbine starts to rotate, then drives generator to realize power generation by turbine；Rotating ball can be steel ball or glass steel ball；
Use environment of the present invention is in seabed, therefore, using steel ball and glass steel ball so that the corrosion proof function of rotating ball in the seawater
Preferably；Rotating ball can also use gravity larger, good ball of Corrosion Protection.

7. power station using ocean currents according to claim 1, which is characterized in that the leaf frame further includes outside frame, described
Outside frame is that a radian is 100 ° and the vertical arc panel that is counterclockwise bent, the top surface of the vertical arc panel with
Upper mounted plate is fixed, and bottom surface and the bottom plate of vertical arc panel are fixed；The vertical arc panel and outermost end blade-section weight
It is folded.
8. a kind of electricity-generating method of power station using ocean currents, it is characterised in that：Described in any one in claim 1-7
Power station using ocean currents, the power generator are fixed on seabed by pedestal and are either suspended in marine by floating drum or are soaked by ship
Not under sea；
When power station using ocean currents be in stand under natural conditions when, it is in the shape that is all closed that resetting-mechanism, which controls several blades,
State；
Under the mobilization of ocean current, when blade wheel structure is rotated along the direction of ocean current, ocean current impacts the blade being closed completely,
Wheel rotation is pushed, impeller is by driving electrical power generators；
When impeller against ocean current direction rotate when, blade is fully open under the promotion of ocean current, at the same adjacent two pieces of blades it
Between form parallel with the ocean current flow direction mouth of a river of crossing so that ocean current passes through without shock, impeller, which is rotated further, drives generator lasting
Power generation.
