Abstract

<P>PROBLEM TO BE SOLVED: To generate electric power by a floating buoy, since efficiency of power generation is undesirable in an air turbine using air compression by rising-lowering of a wave, or the like. <P>SOLUTION: The floating buoy 2 and a floating buoy cover 1 are installed on a vertical bar 3, and a free joint part 12 is connected, and a lever bar bent-shaped gear 6 on the generator 9 side of a lever bar 4 and a freewheel gear 7 are meshed. When a wave 18 lowers, it lowers by idly rotating by a weight in the floating buoy 2, a weight of the vertical bar 3 and the lever bar 4 and a ratchet mechanism of the freewheel gear 7. When the wave 18 rises, it rises by buoyancy of the floating buoy 2, and the lever bar bending-shaped gear 6 rotates the freewheel gear 7, and rotates an installed and fixed generator rotary bar 8, so that a generator 9 generates electricity. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a floating buoy-stick bar wave power generation device for power generation using sea waves.

Conventional wave power generators are inefficient due to the low efficiency of airflow air turbines, etc., and have been removed by the Japan Agency for Marine-Earth Science and Technology in 2000 after approximately 10 years of operation.

      Therefore, wave power generation waves such as airflow air turbines with waves have the disadvantage of being inefficient and have the disadvantage of being impossible to put into practical use.

  The present invention integrates a floating buoy with a floating buoy cover, fastens it with a bolt and nut, and also fastens the upper and lower bars with bolts and nuts, and fixes the upper and lower bar joint and lever bar joint to the free joint. Insert the packing into the fixed point bar to fix the fixed point ball of the fixed point bar and the lever bar part with the fixed point cover. An anti-spinning plane is provided, closed and fixed with bolts and nuts, meshed with the generator's lever rod curved gear and freewheel gear, and the generator rotating bar is scraped and fixed on the anti-spinning plane. When the wave rises and the wave falls, the floating buoy has a weight and a freewheel gear ratchet mechanism. To solve the above problem by fixing to the seabed by a fixing wire maintained at a constant height by a certain air tank.

  The present invention is provided with a large buoyancy floating buoy capable of floating one person with a plastic bottle and ten lever levers on both the left and right sides, and a freewheel gear ratchet mechanism is used to raise and lower the floating buoy. If movement is possible, the diameter of the floating buoy is about 1m and the number of freewheel gears is increased, the density and power generation efficiency will be improved. The width of the floating structure will be 4m for the full length of the lever and 1m for the floating buoy. Becomes 1m, becomes 12m, and the vertical width becomes 15m, so that it does not move up and down by wave swell of 2.3m, and keep the stability by attaching the air tank under the wave swell below sea level. Is possible.

  As shown in FIGS. 1 and 2, the floating buoyco bar wave power generator of the present invention is sandwiched by a floating buoy cover 1 with a floating buoy cover 1 and fixed with a bolt nut 14 and fixed to a vertical bar 3 with a bolt nut 14. As shown in FIGS. 5 and 6, the free joint portion 12 comprising the upper and lower bar joints 12A and the lever bar joint 12B is connected with a bolt and nut 14, and the upper and lower bars 3 As shown in FIG. 3, the lever 4 is sandwiched between the fixed point bar 5A, the fixed ball 5B, and the packing 5C, and the bolts and nuts 14 are closed and fixed. Then, the lever 18 is bent by the ratchet mechanism by engaging the lever rod curved gear 6 on the generator rod 9 side of the lever rod 4 and the freewheel gear 7 fixed to the generator rotating rod 8 by the freewheel gear fixture 7A. If the weight 15 of the floating buoy 2, the floating buoy 2, the floating buoy cover 1, the top / bottom bar 3, and the lever bar 4, the freewheel gear 7 rotates and drops, and if the wave 18 rises, the buoyancy of the floating buoy 2 When the lever lever curved gear 6 rotates the freewheel gear 7, the generator rotating rod 8 is rotated and the generator 9 generates electric power. Further, as shown in FIG. 1, it is provided so as to be kept at a certain height by an air tank 13 attached to the lower part of the floating structure 16, and is provided on the seabed by a fixed wire 17 in preparation for a high wave during a typhoon or the like.

  The fixed point bar 5A and the generator rotating bar 8 are cut parallel in the vertical direction to provide the fixed point bar idle rotation prevention plane 5D and the idle rotation prevention plane 8A, thereby preventing the idle rotation of the fixed point cover 5 and the freewheel gear fixture 7A. .

When the wave swell height is 2 m, the wave swell is 3 m from the fulcrum of the fixed point bar to the floating buoy of the power point and 1 m from the fulcrum of the fixed point bar to the lever rod curved gear at the action point. If the floating buoy rises 2m, the lever-shaped curved gear will be lowered by 60cm and the freewheel gear can be rotated by 60cm.
The buoyancy of the sphere is determined by the amount of water discharged by the floating buoy and the upper / lower bar, lever bar, and weight, and the volume V of the buoy buoy with a diameter of 1 m is V = 4 × π × the cube of the radius ÷ 3 = 4 × 3, 14 × 0,5 to the third power ÷ 3 = 0,523m3 to the power = 523 liters, and the specific gravity of water is 1 kg / liter, the mass W is W = 523 kg, so the buoyancy is F When the weight of the floating buoy / upper / lower bar / lever bar / weight is 103kg, the buoyancy is 523kg-103kg = 420kg, and the lever is 3m long because of the lever principle. × 3 = 1260kg of force can rotate the freewheel gear by 60cm, and if more than 10 freewheel gears are provided, the rotating speed of the generator rotating rod is increased and the large-capacity generator is rotated. I can make it.

  Since the sea is wide, it is designed to increase the amount of power generation and stabilize it even during high waves by connecting vertical structures of about 15 meters long and 12 meters wide with 10 or more floating buoys and freewheel gears on the left and right sides. . In addition, since there are many towns and cities facing the sea all over the world, it can be used. It can also be used as a power source for changing seawater to fresh water, or it can be used as hydroelectric power by pumping seawater into a reservoir on the hill by night electricity.
