Hereinafter, a first embodiment of a power generation device according to the present invention will be described in detail with reference to the accompanying drawings (FIG. 1).
The power generation device according to the present embodiment has, as its basic configuration, a cylinder 10 into which a gas having a pressure higher than atmospheric pressure can be introduced, an intake port 21 arranged on one end side of the cylinder 10, and the intake port 21. An intake valve portion 20 having an intake valve body 22 that opens and closes, an exhaust port 31 disposed on one end side of the cylinder 10, an exhaust valve portion 30 having an exhaust valve body 32 that opens and closes the exhaust port 31, and the cylinder 10 And a piston 40 that reciprocates inside.

  In the present invention, the operating range of the piston 40 moves as the high pressure gas H introduced into the introduction space 11 expands from a position where the introduction space 11 into which the high pressure gas H is introduced is left in the cylinder 10. The stroke length is set. Work is performed when the high-pressure gas H expands, and can be converted into generation of power by the reciprocation of the piston 40. The reciprocating motion of the piston 40 is converted into a rotational motion by, for example, the crank mechanism 45, whereby the generator can be rotated to generate electric power. According to this, by intermittently introducing the high-pressure gas H, energy from the heat source that generates the high-pressure gas can be efficiently converted into power.

  Further, in the present invention, after the high-pressure gas H is introduced into the introduction space 11, the intake valve opening / closing mechanism 25 that closes the intake port 21 with the intake valve body 22, and after the high-pressure gas H expands and moves the piston 40 with respect to the stroke. An exhaust valve opening / closing mechanism 35 that opens the exhaust port 31 with the exhaust valve body 32 is provided. The intake valve opening / closing mechanism 25 and the exhaust valve opening / closing mechanism 35 can be rationally configured by a drive device such as a cam mechanism 25A, 35A (see FIG. 2) or an electromagnetic valve (not shown) described later.

  In this embodiment, the reciprocating motion of the piston 40 is constituted by a piston rod 41 having one end rotatably fixed to the piston 40 and a crank 42 having the other end of the piston rod 41 rotatably fixed. It is converted into rotational motion by the crank mechanism, and the rotational power of the crankshaft 43 can be generated. Reference numeral 12 denotes an intake pipe, which is a passage for introducing steam or the like as high-pressure gas. Reference numeral 13 denotes an exhaust pipe, which is a passage for discharging the pressure gas whose pressure has decreased after the piston 40 is operated.

  According to the present embodiment, for example, steam is generated through the boiler by the heat energy obtained by burning biomass or the like, and the steam pressure can be used. When the piston 40 is located at the point A, for example, 10 atm of steam is introduced from the intake port 21, and then the intake port 21 is closed by the intake valve body 22. Then, due to the expansion of the steam, the piston 40 moves to a point B corresponding to the bottom dead center, and when the pressure is reduced to 2 atm, for example, the piston 40 operates the crank 42 via the piston rod 41. And convert it to rotational power. In this embodiment, the crank 42 is actuated by the action of the flywheel 50, and the piston 40 returns to point A corresponding to the top dead center of the cylinder 10 by reversing its movement. At this time, the exhaust valve portion 30 is opened, and the exhaust gas whose pressure is reduced is discharged from the cylinder. The rotational power output in this way can be used as power for power generation.

In addition, 62a is a check valve body, and is provided in the gas receiving part 62. The gas receiving part 62 is provided so as to be closed when the gas G is raised and opened and opened when the gas is lowered.

  According to this, when the exhaust pressure of the pressure gas is 2 atm, it can be introduced into water at a water depth of 9 m, for example, and the pressure gas is received by the gas receiving portion 62. Then, the endless track 61 can be operated by the buoyancy of the pressure gas. Further, as the gas receiving part 62 rises in the underwater W, the gas (pressure gas) increases in volume as the water pressure decreases, so that its buoyancy increases. According to this, rotational power can be obtained from, for example, the lower rotating shaft 61 a of the endless track 61. This rotational power can be output together with the rotational power of the crankshaft 43 described above using a differential gear.
