Description

Swing plate type electric generating equipment using wave energy

The present invention is the electricity generating device of relevant wave energy, the invention that the transverse movement that particularly utilizes rocker to receive ripple can be generated electricity.

With regard to being fixed on longshore electricity generating device, what be applied at present is to utilize heaving of the sea to enter fixing tube or grotto generation pressurized air promotion air turbine machine generating (Japanese beneficial field formula).Because air has compressible character, working pressure is lower, so generated output is little, and efficient also has twenties percent.

The object of the present invention is to provide a kind of simple in structure, the efficient height, power is big, shock resistance, lower-cost electricity generating device.

The present invention utilizes the rocker-end that floats on the surface upwards to lift up lower surface outwards to protrude.The other end is hinged on the sea wall or (following abbreviation bearing) on the precast reinforced cement bearing-receive wave energy.

The free wheel device that two identical overcoats are pulley is contained on the transmission shaft in the same way side by side.Transmission shaft is located in the bearing support of fixing the bearing upper-end surface, respectively has the posttension that winds with one circuit of a cable wire to fasten two ends at strut on two pulleys, and two cable wires are around on the contrary.When rocker was upwards swung by the wave power effect, the strut and last two cable wires thereof that promote to be hinged on the rocker moved, and the one cable wire makes institute rotate counterclockwise and drive transmission shaft around pulley and rotates in the same way; Another cable wire makes institute clockwise rotate and surmount on transmission shaft around pulley.Rocker makes progress pivot angle when being no more than 75 °, and by its gravity backswing, the spring that the rocker compression is fixed on the bearing when surpassing 75 ° speeds up backswing.Above-mentioned two cable wire effects are opposite during backswing.Rocker is subjected to the wave power effect to swing up and down the equal transmission shaft that can make and produces torque in the same way.

The torque of transmission shaft and gear increaser, generator electric can be generated electricity with coupling.

When rocker length was definite value, generated output was directly proportional with the rocker area.The rocker pivot angle that makes progress depends on wave height, and the gravity of rocker is depended in the torque that cable wire produced during backswing.The generating conversion ratio reaches about 50%.

The beneficial field formula electricity generating device conversion of energy process of Japan is: wave energy, air pressure energy, mechanical energy, electric energy.And this device directly becomes the mechanical energy generating to wave.Because the compressibility conversion ratio of air is low, so the present invention is more simple in structure than beneficial field formula, power is big, the efficient height.

The end that floats on the surface has upwards been lifted up lower surface and has outwards been protruded in this device, and the rocker that the other end is hinged on the bearing can not only absorb the catenary motion energy of ripple, and can also absorb the bigger transverse movement energy of energy.

Strut can not only and can also be transformed into garden Zhou Yundong to straight reciprocating motion swing in this device.And there are not " dead point " position and idle stroke.

In this device because by cable wire flexible element transferring power in the middle of this, so have shock resistance and overload protective function.

In addition, the present invention is because the component that do not exist the underwater construction problem to reach main and contact with sea water adopt the steel of seawater corrosion resistance to make and outer surface is coated with the anticorrosive paint double protection, and cost of electricity-generating is lower.

Bottom introduces the solid yardage method of executing in conjunction with the accompanying drawings:

Accompanying drawing 1 is the side view of rocking plate type wave wave energy generating set, and accompanying drawing 2 is that Figure 1A is to enlarged view.

By position shown in Figure 1 rocker (1) left end is hinged on that bearing (2) is gone up or the elevation of water of bank rock on.Rocker (1) connects with spherical hinge with strut (3) lower end.

The free wheel device (4) (5) that two identical overcoats are pulley is contained on the transmission shaft (6) in the same way side by side, and transmission shaft (6) is located at bearing (2) upper-end surface and is fixing in the bearing support (7).Respectively have the posttension that winds with one circuit of a cable wire to fasten at the two ends of strut (3) on two pulleys, two cable wires are around on the contrary.When rocker (1) was subjected to the wave power effect upwards to put above 75 °, the garden spring that rocker (1) compression is fixed on the bearing (2) speeded up backswing, and (1) pressure spring of rocker in the time of 80 ° also contacts spacing with the spring inner guide.Rocker (1) is subjected to the wave power effect to swing up and down the equal transmission shaft (6) that can make and produces torque in the same way.

Transmission shaft (6) and gear increaser, generator connects (not drawing in the accompanying drawing) with coupling.

Rocker (1) adopts steel plate welded hollow structure, and strut (3) can be made of I-steel.Pulley free wheel device (4) (5) is selected the roller mono-directional overrun clutch for use.Component anti-and contact with sea water all adopt the manufacturing of 09MnN ь low alloy steel, and are coated with fiberglass paint outward.

In order to increase the frictional force between cable wire and the pulley, bag one deck rubber cord on the pulley working surface.

This device can all be installed on the bearing (2), and transport to seashore during use and shift certain depth of water position onto, but also assembled on site.
