The configuration of the present invention will be described in detail as follows.

First, the fluid circulating apparatus 100 will be described.

The fluid circulating device 100 supplies water to the inside of the tank, compresses the air inside the tank, and discharges the air to one side. The difference between the tides can be used. Preferably, the fluid circulating apparatus 100 according to the first embodiment is provided with a water inlet 111 at a lower side so that water can be introduced into the storage space inside the water circulation trough, And a tank main body 110 in which the water introduced through the water inlet 111 is discharged into the tank while being compressed in the inside of the storage space at the same time as the inside air is compressed, An exhaust pipe 120 provided at an upper portion of the tank main body 110 and an outside air inside the tank main body 110 so that water introduced into the storage space at the time of low- (Not shown).

In other words, the coast where the tidal current and the tidal force periodically occur is formed as the bottom surface G is inclined downward from the land to the sea side. Therefore, when the water starts to flow into the first tank body 110a through the inlet 111 of the first tank body 110a located at the end of the tide, the air existing in the inside of the first tank body 110a is compressed, To the adjacent second tank body 110b.

At the same time, the air existing in the second tank main body 110b moves toward the third tank main body 110c through the air connecting pipe 115 while the water is compressed and compressed inside the storage space. The air that has moved to the third tank body 110c is compressed together with the air existing in the third tank body 110 and discharged through the exhaust pipe 120 provided at the upper part. The air exhausted through the exhaust pipe 120 operates the fluid pressure turbine 200 and generates electricity through the power generator 300. The detailed configuration of the fluid pressure turbine 200 and the power generation unit 300 will be described later.

In this case, the inlet 111 and the drain 113 are provided with one-way check valves 112 and 114, respectively, to prevent backflow of water flowing into or out of the tank main body 110.

As shown in FIG. 2, a plurality of the tank main bodies 110 are disposed adjacent to each other in the four directions, and the air connecting pipes 115 are connected to each other, thereby increasing the amount of circulated air. The air compressed and circulated in the plurality of tank bodies 110 is continuously collected into one tank main body 110 having the exhaust pipe 120 at the same time as the water in the storage space cools up during the tide, And is discharged through an exhaust pipe 120 provided in the tank body 110 disposed on the land side. In this case as well, an intake pipe 130 is provided together with one side of the exhaust pipe 120.

Referring to FIG. 3, the fluid circulating device may be modified to use water stored in a reservoir or resources such as flowing river.

In this case, the control unit (not shown) receiving the signals sensed by the first and second sensing sensors 117a and 117b sequentially controls opening and closing of the first and second control valves 111a and 113a.

Also, the exhaust pipe 120 and the intake pipe 130 are provided with one-way check valves 121 and 131, respectively, so as to prevent backflow of exhausted or intake air, as in the case of the first embodiment.

Referring to FIG. 4, a plurality of fluid circulating apparatuses 100 'according to the second embodiment of the present invention are connected in series along a direction in which water flows.

The fluid pressure turbine 200 is operated using air circulated while being sucked and discharged by the fluid circulation apparatuses 100 and 100 'having the above-described structure, and water introduced into and discharged from the tank main body, The power generation unit 300 connected to the pressure turbine 200 can generate electricity.

5 and 6, the fluid pressure turbine 200 may be installed in any one or both of the exhaust pipe 120 and the intake pipe 130 of the fluid circulating apparatus 100 And a rotary vane 220 rotated by a flow rate of air sucked or discharged.

The fluid pressure turbine 200 may be installed in a water inlet 111 through which the water flows into the tank body 110 or a water outlet 113 through which the water is discharged and may be operated by using the flow rate of the water .

Preferably, the fluid pressure turbine 200 includes a tubular housing 210 having a groove portion 211 bent in a U-shape or a V-shape, And a rotary vane 220 rotatably coupled to the axis line.

The power transmission means 310 connecting the fluid pressure turbine 200 and the power generation unit 300 to be described later is installed on the rotating shaft 221 which is exposed to the groove portion 211 of the housing 210, Thereby shielding against contact with air passing through the interior of the housing 210.

In this case, the rotary vane 220 is formed of a lightweight synthetic resin material, preferably a PVC (polyvinyl chloride) material. Therefore, the rotating vanes 220 can be efficiently rotated by the air passing through the inside of the housing 210.

In addition, a spiral protrusion 213 may be formed along the longitudinal direction on the inner circumferential surface of the housing 210 to increase the flow velocity of air passing through the protrusion 213.

The power generator 300 converts the mechanical energy of the fluid pressure turbine 200 into electrical energy. The power generating unit 300 preferably includes a plurality of gear trains or one or more electromagnetically driven electromotive elements on a rotating shaft 221 coupled to the fluid pressure turbine 200 so as to be exposed to the outside of the housing 210 The power transmission means 310 of the power transmission mechanism 300 is connected. Since the power transmission means 310 is installed in the groove of the housing 210, the resistance applied to the rotary vane 220, which rotates inside the housing 210, can be reduced as much as possible, 300 can be improved.

And a heating device 123 for heating and expanding the discharged air using one of a heat source such as solar heat, a hot air heater, and a gas is connected to the exhaust pipe 120 connected to the fluid pressure turbine 200 to supply air . (See Figs. 1 and 3)

The end portion 125 is positioned below the tank 410 and the air discharged through the end portion 125 is stored in the tank while moving upward by the force of the buoyant force. The pressure of the air stored in the upper portion of the tank 410 is increased by the air stored in the tank 410, and the height of the water in the tank 410 is lowered by this pressure to automatically adjust the pressure.

In this case, a unidirectional check valve 121 is provided at the end portion 125 to prevent backward flow of the supplied air. In addition, another exhaust pipe 120 'for discharging the air inside the tank 410 is provided on the upper part of the tank 410.
