A shaft support 330 may be installed between the first crank shaft 320 and the first crank shaft 320 so that the center of rotation can be supported. A bearing may be installed in the shaft support 330. .

At this time, each of the first crank shaft 320 may be connected to the gear coupling portion 340, the gear coupling portion 340 is the first crank shaft 320 of the previous step, when the inside Gear teeth of an installed key shape may be engaged to sequentially transmit power to the first crankshaft 320.

In addition, since the first pistons 350 are connected to the respective first crank shafts 320, reciprocating linear motions are performed.

The first piston 350 is coupled to the first cylinder 360 to be reciprocated, and sucks and compresses air in the first cylinder 360 to discharge it.

A first check valve 371 is installed at the lower intake side of the first cylinder 360, and the first check valve 371 opens the valve when the first piston 350 is raised to draw in outside air. Meanwhile, when the first piston 350 descends, the valve is blocked to prevent the compressed air inside from escaping to the outside.

At this time, the present invention can be configured to allow the external air to naturally supply to the first check valve 371 during the ascending operation of the first piston 350 as described above, in another way, the air of the first driving unit 100 A separate air pipe (not shown) is connected between the tank 110 and the first check valve 371 so that the air pressure discharged from the air tank 110 during the ascending operation of the first piston 350 opens the air pipe.

At this time, it is preferable to separately install another check valve on the air pipe connected as described above.

In this way, by connecting a separate air pipe between the air tank 110 and the first check valve 371, the compressed air discharged from the air tank 110 during the lifting operation of the first piston 350 is the first check By forcibly flowing into the valve 371 so as to be directly supplied into the first cylinder 360, the compressed air discharged from the air tank 110, even if a pressure drop occurs due to energy loss in the third driving unit 300 Forcibly introduced into the first cylinder 360 to compensate for the pressure drop in the cylinder and to allow each cylinder to operate smoothly.

In addition, a second check valve 372 is installed on an exhaust side formed near the intake side of the first cylinder 360, and the second check valve 372 opens the valve when the first piston 350 descends. By opening the compressed air to move to the next path, at the same time, the valve is blocked when the first piston 350 moves up to block the compressed air from flowing backward.

That is, the air compressed in the first cylinder 360 of the previous stage is supplied to the first cylinder 360 of the next stage, and at this time, it is supplied to the first cylinder 360 of the next stage after being compressed again. By repeating this process, high pressure compressed air can be generated.

3 illustrates a process of compressing a total of six stages of a cylinder, but this is only an example for helping the description of the present invention, but is not limited thereto. That is, the cylinder compression process may be performed only one step, or may be subjected to a compression process of six or more steps.

Between the first cylinder 360 and the first cylinder 360 adjacent to each other, a first air engine 380 providing a movement path of the compressed air is connected, and a second check on the first air engine 380. The valve 372 can be provided.

As described above, the air that has undergone the multi-stage compression process in the third driving unit 300 is supplied through the intake valve 170 of the air tank 110 of the first driving unit 100 to supply compressed air to the inside of the air tank 110. It is filled.

On the other hand, the rotational power of the first crank shaft 320 is transmitted to the output shaft 390, the rotational power of the output shaft 390 is transmitted to the power generation unit 500, driving the power generation unit 500 to drive electrical energy To generate the, the electrical energy generated through the power generation unit 500 can be used to charge the storage battery.

Meanwhile, the rotational power may be branched from the output shaft 390 of the third driver 300 to be transmitted to the fourth driver 400.

4 is a schematic view showing a fourth driving unit of the power generating apparatus according to an embodiment of the present invention.

Referring to FIG. 4, the fourth driving unit 400 includes a power transmission shaft 410, a second crank shaft 420, a clutch unit 430, a second piston 450, a second cylinder 460, The third check valve 471, the fourth check valve 472, and the second air engine 480 may be configured to include a configuration.

First, the power transmission shaft 410 is constantly rotated by receiving power from the output shaft 390 of the third driving unit 300, the output shaft 390 and the fourth driving unit 400 of the third driving unit 300. A belt and a pulley may be connected between the power transmission shafts 410 to receive power. At this time, not only the connection of the belt and the pulley, but also may be configured to receive power through the coupling of gears or chain gears.

Next, the second crankshaft 420 is coupled to the power transmission shaft 410 so as to interlock when the power transmission shaft 410 rotates.

The second crankshaft 420 is a component for receiving the rotational movement of the power transmission shaft 410 and converts it into a linear movement of the second piston 450. The second piston 450 is coupled to the eccentric shaft to perform reciprocating motion in the vertical direction.

In this case, the second crankshaft 420 may be installed by continuously connecting one or more plurality in the axial direction, and each of the second crankshafts 420 may be arranged to alternately operate the top dead center stroke and the bottom dead center stroke. Can be.

An axis support may be installed between the second crankshaft 420 and the second crankshaft 420 so that the center of rotation may be supported. A bearing may be installed in the shaft support.

In addition, since the second pistons 450 are connected to the respective second crank shafts 420, reciprocating linear motions are performed.

The second piston 450 is coupled to the second cylinder 460 to reciprocate, and sucks and compresses air in the second cylinder 460 to discharge it.

A third check valve 471 is installed at the lower intake side of the second cylinder 460. The third check valve 471 opens the valve when the second piston 450 is raised to draw in outside air. Meanwhile, when the second piston 450 descends, the valve is blocked to prevent the compressed air inside from escaping to the outside.

In addition, a fourth check valve 472 is installed at an exhaust side formed near the intake side of the second cylinder 460, and the fourth check valve 472 opens the valve when the second piston 450 descends. Opening the compressed air is moved to the next path, and at the same time, the valve is blocked when the second piston 450 moves up to block the compressed air from flowing backward.

The reason why the clutch unit 430 is formed is that when the compressed air is filled in the air tank 110 by a predetermined value or more, the power transmission between the third driving unit 300 and the fourth driving unit 400 is temporarily blocked. This is to prevent the generation and supply of auxiliary compressed air in the fourth driving unit 400.

The clutch of the clutch unit 430 may be applied to many examples. However, the clutch may be configured as follows.

For example, when the pressure plate 120 and the pressure rod 130 extending therefrom retreat as the compressed air is gradually filled in the air tank 110 of the first driving unit 100, it interlocks with the pressure rod 130. And form a clutch arm 431 to be moved forward and backward together, and the clutch arm 431 is connected to the clutch member 433 which is axially moved between the two separate power transmission shafts 410, To pass and block.

At this time, the clutch member 433 is a rotating body splined to rotate on the power transmission shaft 410, the clutch arm 431 is a structure for supporting the outer diameter of the clutch member 433 in a state capable of slipping. It can be configured to have.
