Description

Variable gravity-center floating box type wave energy transducer

The present invention relates to a kind of energy conversion device, particularly a kind of variable gravity-center floating box type wave energy transducer.

Along with a large amount of exploitations, the utilization of oil, coal resources, energy crisis occurs in many countries, area gradually, and energy problem has become worldwide problem, and people begin to recognize the significance that taps a new source of energy.And the ocean is pollution-free by the energy, inexhaustible in theory, is a kind of very economical energy, causes people's great interest day by day.People are in order to develop the huge energy that ocean wave stores, solve to garrison in coastal and island, the electrical problem of unit and vast remote fishing village, to ocean wave energy being converted to the problem of electric energy, as many discussions and research, following several representational conversion methods have appearred the end of the sixties and the nineties:

One, Cockerell raft (Cockerall-Hagen raft); Articulated slab is across the sea floating, and wave motion relatively rotates plate, compresses or draw back the two ends, hinged place to be separately fixed at piston on the two boards, by the fluid pressure switching energy.

Two, the special duck (Salter ' s nodding duck) of Sol; The transverse section is the energy extraction device of " cam " shape, and " camshaft " swims on the water surface for substantially horizontal.Because the floating of wave and the pressure that velocity of wave causes make " cam " obtain energy around rotational.

Three, the light rectifier of Russell (Russell rectifying flaps): the motor shaft lengthening, at the other end filled with water turbine, this device is stood in the pond, water turbine is below.Pond water inlet during crest, tank water flows out during trough, promotes water turbine, and motor is generated electricity.

Above several method, Cockerell raft are made, are applied not, transformation of energy all compares difficulty and wind loading rating is poor.The special duck of Sol is the transformation of energy difficulty then, and many " ducks " are contained in anchoring difficulty on the axle.The people that russell rectifier or the device similar to it are studied now is more, but it will carry out geotechnique's construction, can not be away from the seashore setting.

Purpose of the present invention for people provide a kind of simple in structure, easy Wave energy converting device is set.

For achieving the above object, the present invention adopts following technological scheme: two slideways, a part internal gear and a slide block are set in the cuboid casing.Slide block is fixed on the gear on the framework, directed driver, planet by framework and serial connection and increases and pass device and generator constitutes, and its gear is meshed with part internal gear between slideway.It is across the sea floating, and under the effect of wave, casing hangs down and swings and the wide-angle pitching, and slide block slidably reciprocates along slideway, and the gear on it is driven in rotation, and the rotor by directed driver, planet gear speeder driving DC generator makes generator send electric energy.

The present invention makes simply, transport easily, lay conveniently, can be away from the seashore setting, transferable and be not subjected to tidal effect.

The invention will be further described below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present invention.

Fig. 2 for Fig. 1 along A to office cut open schematic representation (amplification).

Fig. 3 is the sectional view (amplification) of Fig. 1 along B-B.

As Fig. 1, Fig. 2, shown in Figure 3, this transducer is made of casing 11, slideway 2, part internal gear 1, slide block 19 and damping spring 3.Casing 11 is rectangle, and makes with steel plate and stiffener, comes in and goes out for making things convenient for the repairman, which is provided with manhole 6.Slideway 2 has two, along casing 11 length direction settings, is fixed on the slideway support that is made of riser 17, transverse slat 15 and stiffening rib 16.Slideway 2 is a circular arc in vertical vertical plane, can make slide block 19 these place's slideway 2 directions when slideway 2 endpoint locations like this is level, and can make casing 11 in the pitching process slide block 19 when slideway 2 arbitrary positions, the slideway 2 of this position changes little with the horizontal plane inclination angle, thereby velocity variations was little when slide block 19 was slided, and is steady in order to generator output voltage.Part internal gear 1 is fixed on the gear stand that constitutes with transverse slat 12, riser 13 and stiffening rib 14 between slideway 2, and its standard pitch circle center of circle overlaps with the slideway 2 circular arc centers of circle.Slide block is made up of framework 5, gear 4, directed driver 10, planet gear speeder 9 and DC generator 8.Gear 4, directed transmission device 10, speed increaser 9 and generator 8 are connected and fixed in turn on framework 5, and its middle gear 4 is meshed with part internal gear 1.When casing 11 pitchings, framework 5 drives these devices (general name slide block 19) and slides on slideway 2.Since gear 4 all the time with part internal gear engagement, so slide block 19 when sliding driven gear 4 rotate, by directed driver 10, planet gear speeder 9, give the rotor of generator 8, rotor revolution and send electric current with motion and transmission of power.

Directed driver 10 directly adopts disclosed utility model patent " directed transmission device ", and the patent No. is 93237664.9, just no longer elaborates at this.Its effect is when slide block 19 changes glide direction, makes generator 8 rotor gyratory directions constant.For control generator 8 rotor speeds, reach the steady purpose of output voltage, in generator 8 rotating shafts centrifugal brake or electromagnetic brake are housed.

In addition, two fins 18 are longitudinally arranged at casing 11 bottoms, and its effect is when casing 11 floats on the sea, make the length direction of casing 11 consistent with the velocity of wave direction---make 180 ° of wave encounter angle convergences.For ease of laying this transducer across the sea, respectively there is a minor axis 7 both sides, casing 11 middle part in addition, and it is hinged with the scaffold that connects casing 11 (otherwise designed) to make this transducer pass through minor axis 7.

The concrete size of this transducer must be by the wave parameter design of specifically laying the marine site.Several transducer output circuit parallel connections can obtain powerful electric current, just can obtain threephase AC for land utilization, operation on the sea by rotary substation (being located on the underwater ship) again, can be charge in batteries with direct current directly also.
