Description

  The present invention relates to a power generator using a wave that generates power by operating a generator by a wave generated, that is, a pressure generated by the vertical movement of the wave.

Currently, the earth is emitting large amounts of carbon dioxide as a result of the massive consumption of fossil fuels. And this carbon dioxide emission is also a cause of global warming, and the problem has become serious enough not only to threaten the lives of animals and plants on the earth, but also to threaten the destruction of mankind . Thus, there is a need for an alternative to using fossil fuels that emit large amounts of carbon dioxide. One of the seed substitutes is biomethanol produced from food and agricultural products such as wheat and corn. However, because it uses food and agricultural products as its raw material, it is not necessarily intended to cause shortages and soaring foodstuffs. Not achieved. In addition, there is wind power generation using wind, but an installation environment where wind is easy to blow cannot be obtained everywhere.
Each of these alternative energies has excellent characteristics, and there is no doubt that those using natural energy are excellent for suppressing carbon dioxide emissions.
From this point of view, the present invention intends to provide a power generation device that generates power using natural energy called wave waves and is inexhaustible, can be generated anywhere, and has no carbon dioxide emission. .

  The problem to be solved is to secure electric power by using inexhaustible natural energy everywhere that does not emit carbon dioxide called wave waves.

  The most important feature of the present invention is to obtain electric power without discharging carbon dioxide by generating electric power by effectively using wave motion.

  The power generation device using the wave of the wave of the present invention can generate the generator using the wave of the up and down movement that constantly undulates, and therefore has an advantage of ensuring clean power with no carbon dioxide emission. is there.

  The purpose of rotating the generator by moving the hover floating on the surface of the water up and down by the wave motion was realized with a simple and minimal number of parts.

  FIG. 1 is an overall view of a first embodiment of the device according to the present invention, wherein 1 is a base placed on the sea surface (water surface) S. FIG. This base 1 is fixed to a place that is completely stable without being swung by waves, for example, a water bottom, a land, or a ship that is relatively stable with little wobble due to waves, such as a large ship. It can be fixed or used on the large ship deck itself. Although not shown, the base 1 is always provided with a predetermined interval l between the lower surface 2 and the sea surface S (the most floating position of a hover 9 to be described later) by an automatic elevating device equipped with a sensor for measuring the distance. Adjusted.

  On the base 1, a rotary generator 3 that rotates to generate electric power is disposed. In addition, a cylindrical guide tube portion 4 is provided on the lower surface of the base 1 so as to communicate with the sea. The guide cylinder portion 4 includes an upper slider portion 5 having a relatively small diameter and a lower cylinder portion 6 having a lower diameter communicating with the slider portion 5.

  A pressing portion 7 is arranged on the slider portion 5 so as to be slidable up and down. The pressing portion 7 is connected to a hover 9 by a piston rod 8 described later. .

  On the other hand, a hover 9 connected to the piston rod 8 is swingably arranged in the cylinder portion 6 so as to be movable up and down while floating on the sea surface S. The hover 9 is formed using a balloon in which air is injected, or a lightweight material that is easily swung by a uniform wave made of foamed polystyrene. The hover 9 is arranged with a small gap from the inner wall 10 of the cylinder part 6 and can float to the upper surface of the cylinder part 6, that is, the uppermost part by an upward wave. Further, as shown in the figure, the hover 9 is formed in a spherical surface at the portion facing the inner wall 10 of the cylinder portion 6 as shown in FIG. As a result, the hover 9 can smoothly swing up and down while avoiding a situation in which the inner wall 10 is caught in the cylinder portion 6.

Further, a retaining latching portion 6 a is provided at the lower end of the cylinder portion 6. The retaining locking portion 6a prevents the hover 9 from coming out from the cylinder portion 6 to the outside.

  Further, the pressing portion 7 and the generator 3 are interlocked and connected by a relay member 11. This relay device 11 is fixed to the base 1 like the generator 3 and is connected to the pressing portion 7 with a connecting rod 12 at the front end side, and a rotatable crank 13 and a coaxial flywheel of the crank 13 and the axis 14. 15 and a belt 17 suspended from the flywheel 15 and the rotating shaft 16 of the generator 3. The pressing portion 7 is provided such that the motion center line C is biased without passing through the axis 14 of the crank 13.

  In such a configuration, the hover 9 floats on the water surface S in the cylinder portion 6, and repeats the vertical movement freely while swinging in the inner wall 10 of the cylinder portion 6 by receiving the wave motion. At this time, since the portion of the hover 9 that faces the inner wall 10 of the cylinder portion 6 is formed into a spherical surface, a situation in which the hover 9 is caught on the inner wall 10 of the cylinder portion 6 does not occur. The cylinder portion 6 is smoothly swung up and down. As the hover 9 swings up and down, the pressing portion 7 connected to the hover 9 via the piston rod 8 is guided in the slider portion 5 and slides up and down. The upward pressing force of the pressing portion 7 is transmitted to the crank 13 via the connecting rod 12 to rotate the crank 13. At this time, since the generator 3 and the relay member 11 are arranged on the base 1 fixed to a portion that is not affected or hardly affected by the waves, the pressing force from the pressing portion 7 is reliably applied to the crank 13. The crank 13 can be rotated. When the crank 13 is rotated, the flywheel 15 having the coaxial shaft center 14 is rotated at the same time, and the rotational force is transmitted to the rotating shaft 16 of the generator 3 via the belt 17 to rotate. It will generate electricity.

  In this way, since the power can be generated using the natural force of wave waves everywhere on the earth, clean energy without carbon dioxide emission can be provided permanently.

  FIG. 2 is an overall view of the second embodiment. This is a generator 21 using a semiconductor piezoelectric element, whereas the first embodiment uses a rotary generator 3 as a generator. A generator 21 using a piezoelectric element is disposed on the base 1 at an upper portion of the slider portion 5 of the guide tube portion 4.

  In the second embodiment, when the hover 9 floats on the water surface S in the cylinder portion 6 and repeats up and down movements in the cylinder portion 6 by receiving wave waves, the hover 9 Along with the vertical swing, the pressing portion 7 connected to the hover 9 via the piston rod 8 slides up and down in the slider portion 5. The pressing of the pressing portion 7 pressurizes the generator 21 using the piezoelectric element, and the generator 21 generates power.

  The thing of this 2nd Example differs from what used the rotary generator 3 of 1st Example, and even if there is no relay member 11, it generates electric power only by the upward press of the press part 7 by the hover 9. Therefore, a simpler configuration can be achieved.

  By using the natural energy of wave motion to generate electricity, you can generate electricity anywhere, regardless of where you have water. Infinite power can be generated.
