Thermo power, hydro power and nuclear power are intensively used nowadays for driving power generator means to generate electricity. Using hydro power for generating electricity is one of the most 15 cost-effect ways. However, building a dam for keeping back the water of a river for use in generating electricity may damage the environment and destroy the relation of the living things to their environment. Using thermo power to boil water for generating electricity consumes a 20 big volume of fuel oil, and produces toxic gas that pollutes the air. Using nuclear power for generating electricity is expensive. Besides, it is difficult to properly dispose of waste water and material from a nuclear power plant.
Therefore, these conventional power generating methods 25 are not satisfactory in function. Further, the supply of natural flow power, for example the kinetic energy of the wind, the tide of the sea, etc., is inexhaustible. There are scientists trying hard to utilize natural flow power for generating electricity without damaging the environment.

DETAl~.Fn DESCRIPTION OF TIIE PREFERRED
EMBODIMENT
Referring to Figures 1 and 2, a water 20 reservoir system 1 in accordance with a first embodiment of the present invention comprises broadly a water drawing unit 11, and a water reservoir unit 2 for collecting water drawn from the water drawing unit 11. The water drawing unit 11 comprises a plurality of power machines 3 25 adapted to receive natural flow power, and a plurality of pumps 32 disposed in communication with a water source and respectively driven by the power machines 3. The water reservoir unit 2 comprises a plurality of filter tanks 21 respectively connected to the pumps 32 to receive water from the water source, a plurality of check valves 5 323 respectively mounted between the filter tanks 21 and the pumps 32 to prohibit a reverse flow of water, a water accumulator 22 connected to the filter tanks 21 by a pipe 20 to collect filtered water, a water tank 23 disposed in communication with the water accumulator 22. The 10 filter tanks 21, the water accumulator 22 and the water tank 23 are arranged in a certain altitude. The filter tanks 21 are arranged one higher than another, and the filter tank which is spaced farther from the water accumulator 22 is disposed higher. A plurality of drain 15 pipes 211 are respectively mounted on the filter tanks 21, the water accumulator 22 and the water tank 23 at a bottom side for carrying off sands from the filter tanks 21, or water from the water accumulator 22 to a hydraulic power generator 221 or from the water tank 23 to other 20 places for utilization. Branch pipes 231 are connected between the drain pipes 211 of the water accumulator 22 and the water tank 23. Control valves 232 are respectively mounted on the drain pipes 211 and the branch pipes 231 to control the flow rate of water and its 25 flowing direction. The power machines 3 are driven to work by the kinetic energy of a natural flow source (for example, the kinetic energy of water waves, wind, the tide of the sea, etc.). When the power machines 3 are started, the pumps 32 are reciprocated to pump water from the 5 water source to the filter tanks 21 through the check valves 323. At the filter tanks 21, solid matter is removed from intake water and then carried away from the filter tanks 21 through the respective drain pipes 211 by means of the control of the respective control valves 232.
10 Filtered water is then delivered from the filter tanks 21 through the pipe 20 to the water accumulator 22 and the water tank 23 (water flows from the water accumulator 22 to the water tank 23 only when the water lever of the water accumulator 22 surpasses the connecting point between 15 the water accumulator 22 and the water tank 23). After a certain amount of water has been obtained in the water accumulator 22 and the water tank 23, the control valve 232 of the drain pipe 211 of the water accumulator 22 is opened to let water flow out of the water accumulator 22 20 to the hydraulic power generator 221, causing the hydraulic power generator 221 to be driven to generate electricity. Alternatively, the control valve 232 of the drain pipe 211 of the water tank 23 can be opened to let water flow out of the water tank 23 to the hydraulic power 25 generator 221, or a fish farm or freshwater processing plant. By means of the above arrangement, the system utilizes natural flow power to draw water from a natural water source to a high place, permitting it to be discharged further to power generator means at a low place so that the 5 kinetic energy of the discharged flow of water can be converted into electric energy.
Referring to Figure 3, the power machine 3 is a windmill 31 coupled to the corresponding pump 32 by a reduction gear 33. The windmill 31 10 comprises a tower 34, a transmission mechanism 35 mounted on said tower 34, a plurality of vanes 352 adapted to receive the kinetic energy of the wind and to turn the transmission mechanism 35, a rudder 36 adapted to adjust the direction of the vanes 352. The 15 transmission mechanism 35 comprises a main shaft 351 coupled to the vanes 352, a link 353 having one end coupled to the main shaft 351 by a set of meshed bevel gears 354 and an opposite end coupled to the pump 32 through the reduction gear 33. The water input port of 20 the pump 353 is connected to the sea by a water pipe 321.
When the vanes 352 are turned by the wind, the rotary power of the vanes 352 are transmitted through the main shaft 351 to the link 353 and then to the pump 32 via the reduction gear 33, causing the pump 32 to pump water 25 from the sea into the water pipe 321, permitting pumped water to be further delivered through a water delivery pipe 322 to the corresponding filter tank 21 of the water reservoir unit 2.
Referring to Figures 4 and 5, a water 5 reservoir system 12 in accordance with a second embodiment of the present invention comprises broadly a water drawing unit 121, and a water reservoir unit 49 for collecting water drawn from the water drawing unit 121.
The water drawing unit 121 comprises a plurality of power 10 machines 4 adapted to receive natural flow power, and a plurality of pumps 400 disposed in communication with a water source, for example, the sea, and respectively driven by the power machines 4 to pump water from the sea to the filter tanks 44 through a respective water 15 delivery pipes 48 and a respective check valve 241 in the respective water delivery pipe 48. The water reservoir unit 49 comprises a plurality of filter tanks 44 respectively connected to the pumps 400 to receive water from the sea, a plurality of check valves 241 respectively mounted 20 between the filter tanks 44 and the pumps 400 to prohibit a reverse flow of water, a water accumulator 492 connected to the filter tanks 44 to collect filtered water, and a water tank 493 connected to the water accumulator 492. The power machines 4 are reciprocating 25 mechanisms 40 submerged in the sea. Each reciprocating mechanism 40 comprises a casing 42 defining a receiving chamber 41 and a plurality of water inlets 43 in communication with the receiving chamber 41, a movable bumper 45 moved in the receiving chamber 41 5 and adapted to bear the wave pulse of the sea, and a plurality of spring elements 46 mounted inside the casing 42. Each pump 400 comprises a pressure chamber 421 mounted inside the casing 42 of the corresponding reciprocating mechanism 40 and disposed in 10 communication with the corresponding filter tank 44, a water passage 422 disposed in communication with the pressure chamber 421 and the water inlets 43 of the corresponding reciprocating mechanism 40, an one-way valve 423 mounted in the water passage 422 to let water lS flow from the water inlets 43 to the pressure chamber 421 and to prohibit a reverse flow of water (see the dotted line shown in Figure 5), and a piston 424 connected to the movable bumper 45 and moved with it in the pressure chamber 421. The receiving chamber 41 of the casing 42 20 has a plurality of sliding grooves 425. The movable bumper 45 is supported on the spring elements 46 and mounted with a plurality of rollers 451 adapted to move in the sliding grooves 425. The spring elements 46 impart an outward pressure to the movable bumper 45, causing 25 the movable bumper 45 to be forced against the tide of the sea. Further, a meshed guard 47 is covered around each power machine 4 to prevent fishes and other objects from passing to the inside of each power machine 4.
Referring to Figures 4 and 5 again, 5 when the water of the sea enters the receiving chamber 41 through the water inlets 43, it flows into the pressure chamber 421 through the water passage 422, causing the pressure chamber 421 to be filled up with water, at the same time the movable bumper 45 is pushed to the front 10 side of the receiving chamber 41 by the spring force of the spring elements 46. When the tide of the sea beats the movable bumper 45 (see the imaginary lines shown in Figure 4), the movable bumper 45 is moved backwards to compress the spring elements 46 and to force water out of 15 the water inlets 43, and at the same time the piston 424 is moved backwards into the pressure chamber 421 to force water out of the pressure chamber 421 into the corresponding water delivery pipe 48. When water is forced into each water delivery pipe 48, it is accumulated 20 therein and stopped from flowing backwards by the respective check valve 241. When the tide of the sea falls, the movable bumper 45 is immediately pushed the front side of the receiving chamber 41 by the spring elements 46 (see the real line shown in Figure 4), 25 permitting water to flow to the inside of the receiving 1 o chamber 41 through the water inlets 43. Therefore, when the tide of the sea rises and falls, water is continuously pumped to the filter tanks 44 through the water delivery pipes 48 by the pumps 400 of the power machines 4.
Referring to Figures 6 and 7, a water reservoir system 13 in accordance with a third embodiment of the present invention comprises broadly a water drawing unit 131, and a water reservoir unit 25 for collecting water drawn from the water drawing unit 131.
10 The water drawing unit 131 comprises a plurality of power machines 5 adapted to receive natural flow power, and a plurality of pumps 52 disposed in communication with a water source, for example, the sea, and respectively driven by the power machines 5 to pump water from the 15 sea to the filter tanks 51 of the water reservoir unit 25 through a respective water delivery pipes 13 and a respective check valve 251 in the respective water delivery pipe 13. The water reservoir unit 25 comprises a plurality of filter tanks 51 respectively connected to the 20 pumps 52 to receive water from the sea, a plurality of check valves 251 respectively mounted between the filter tanks 51 and the pumps 52 to prohibit a reverse flow of water, a water accumulator 252 connected to the filter tanks 51 to collect filtered water, and a water tank 253 25 connected to the water accumulator 252. The power machines 5 are submerged in the sea. Each power machine 5 comprises a vane wheel 53 coupled to one pump 52, and a reduction gear 54 coupled between the vane wheel 53 and the pump 52. The vane wheel 53 comprises S a flywheel 531 and a plurality of vanes 532 raised around the flywheel 531. The pump 52 and the reduction gear 54 of each power machine 5 are mounted on a base 55 under the sea. A meshed guard 56 is covered around each power machine 5 for protection.
Referring to Figure 8 and Figures 6 and 7 again, the vanes 532 are pivoted to the flywheel 531.
When the tide of the sea rises and beats the vanes 532, the vanes 532 at the upper part of the flywheel 531 are turned from a sloping position (see the dotted line shown in 15 Figure 8) to a vertical position (see the real line shown in Figure 8) perpendicular to the periphery of the flywheel 531, and the vanes 532 at the lower part of the flywheel 531 are turned from a vertical position to a sloping position, therefore the vane wheels 53 of the power 20 machines 5 are forced by the tide of the sea to turn ~ counter-clockwise, and the rotary power of the power machines 5 is transmitted to the respective pumps 52 through the respective reduction gears 54, causing the pumps 52 to pump water from the sea to the filter tanks 51 25 for filtration, permitted filtered water to be further delivered to a power generator unit 58 for generating electricity.
Referring to Figures 9 and 11, a water reservoir system 14 in accordance with a fourth 5 embodiment of the present invention comprises broadly a water drawing unit 141, and a water reservoir unit for collecting water drawn from the water drawing unit 141.
The water drawing unit 141 comprises a plurality of power machines 6 adapted to receive natural flow power, and a 10 plurality of pumps 62 disposed in communication with a water source, for example, the sea, and respectively driven by the power machines 6 to pump water from the sea to the filter tanks 81 of the water reservoir unit. Check valves 261 are respectively mounted in the water delivery 15 pipes between the filter tanks 81 and the pumps 62 to prevent a reverse flow of water. The power machines 6 are submerged in the seat. Each power machine 6 comprises a plurality of a vane wheel unit 63, and a reduction gear 60 coupled between the vane wheel unit 63 and the 20 corresponding pump 62. The vane wheel unit 63 comprises a plurality of vane wheels 631 of different diameters arranged in proper order, and is disposed axially against the tide of the sea. The vane wheel 631 which has the biggest diameter is disposed adjacent to the 25 reduction gear 60, and the vane wheel 631 which has the smallest diameter is disposed at the front side far from the reduction gear 60. When the tide of the sea rises and falls, the vane wheels 631 are simultaneously turned, and the rotary power of the vane wheels 631 are transmitted to the 5 corresponding pump 62 through the reduction gear 60, causing the corresponding pump 62 to pump water from the sea to the corresponding filter tank 81. Further, a meshed guard 66 is covered around each power machine 6 for protection.
Referring to Figure 10, a water reservoir system in accordance with a fifth embodiment of the present invention is shown substantially similar to the aforesaid fourth embodiment with the exception of the power machines. According to this embodiment, the power 15 machine, referenced by 7, is protected by a meshed guard 74, comprising a plurality of vane wheels 71 connected in parallel by bevel gears 73, and the vanes 72 of the vane wheels 71 are disposed at different axial positions.

EMBODIMENT
Referring to Figures 1 and 2, a water 20 reservoir system 1 in accordance with a first embodiment of the present invention comprises broadly a water drawing unit 11, and a water reservoir unit 2 for collecting water drawn from the water drawing unit 11. The water drawing unit 11 comprises a plurality of power machines 3 25 adapted to receive natural flow power, and a plurality of pumps 32 disposed in communication with a water source and respectively driven by the power machines 3. The water reservoir unit 2 comprises a plurality of filter tanks 21 respectively connected to the pumps 32 to receive water from the water source, a plurality of check valves 5 323 respectively mounted between the filter tanks 21 and the pumps 32 to prohibit a reverse flow of water, a water accumulator 22 connected to the filter tanks 21 by a pipe 20 to collect filtered water, a water tank 23 disposed in communication with the water accumulator 22. The 10 filter tanks 21, the water accumulator 22 and the water tank 23 are arranged in a certain altitude. The filter tanks 21 are arranged one higher than another, and the filter tank which is spaced farther from the water accumulator 22 is disposed higher. A plurality of drain 15 pipes 211 are respectively mounted on the filter tanks 21, the water accumulator 22 and the water tank 23 at a bottom side for carrying off sands from the filter tanks 21, or water from the water accumulator 22 to a hydraulic power generator 221 or from the water tank 23 to other 20 places for utilization. Branch pipes 231 are connected between the drain pipes 211 of the water accumulator 22 and the water tank 23. Control valves 232 are respectively mounted on the drain pipes 211 and the branch pipes 231 to control the flow rate of water and its 25 flowing direction. The power machines 3 are driven to work by the kinetic energy of a natural flow source (for example, the kinetic energy of water waves, wind, the tide of the sea, etc.). When the power machines 3 are started, the pumps 32 are reciprocated to pump water from the 5 water source to the filter tanks 21 through the check valves 323. At the filter tanks 21, solid matter is removed from intake water and then carried away from the filter tanks 21 through the respective drain pipes 211 by means of the control of the respective control valves 232.
10 Filtered water is then delivered from the filter tanks 21 through the pipe 20 to the water accumulator 22 and the water tank 23 (water flows from the water accumulator 22 to the water tank 23 only when the water lever of the water accumulator 22 surpasses the connecting point between 15 the water accumulator 22 and the water tank 23). After a certain amount of water has been obtained in the water accumulator 22 and the water tank 23, the control valve 232 of the drain pipe 211 of the water accumulator 22 is opened to let water flow out of the water accumulator 22 20 to the hydraulic power generator 221, causing the hydraulic power generator 221 to be driven to generate electricity. Alternatively, the control valve 232 of the drain pipe 211 of the water tank 23 can be opened to let water flow out of the water tank 23 to the hydraulic power 25 generator 221, or a fish farm or freshwater processing plant. By means of the above arrangement, the system utilizes natural flow power to draw water from a natural water source to a high place, permitting it to be discharged further to power generator means at a low place so that the 5 kinetic energy of the discharged flow of water can be converted into electric energy.
Referring to Figure 3, the power machine 3 is a windmill 31 coupled to the corresponding pump 32 by a reduction gear 33. The windmill 31 10 comprises a tower 34, a transmission mechanism 35 mounted on said tower 34, a plurality of vanes 352 adapted to receive the kinetic energy of the wind and to turn the transmission mechanism 35, a rudder 36 adapted to adjust the direction of the vanes 352. The 15 transmission mechanism 35 comprises a main shaft 351 coupled to the vanes 352, a link 353 having one end coupled to the main shaft 351 by a set of meshed bevel gears 354 and an opposite end coupled to the pump 32 through the reduction gear 33. The water input port of 20 the pump 353 is connected to the sea by a water pipe 321.
When the vanes 352 are turned by the wind, the rotary power of the vanes 352 are transmitted through the main shaft 351 to the link 353 and then to the pump 32 via the reduction gear 33, causing the pump 32 to pump water 25 from the sea into the water pipe 321, permitting pumped water to be further delivered through a water delivery pipe 322 to the corresponding filter tank 21 of the water reservoir unit 2.
Referring to Figures 4 and 5, a water 5 reservoir system 12 in accordance with a second embodiment of the present invention comprises broadly a water drawing unit 121, and a water reservoir unit 49 for collecting water drawn from the water drawing unit 121.
The water drawing unit 121 comprises a plurality of power 10 machines 4 adapted to receive natural flow power, and a plurality of pumps 400 disposed in communication with a water source, for example, the sea, and respectively driven by the power machines 4 to pump water from the sea to the filter tanks 44 through a respective water 15 delivery pipes 48 and a respective check valve 241 in the respective water delivery pipe 48. The water reservoir unit 49 comprises a plurality of filter tanks 44 respectively connected to the pumps 400 to receive water from the sea, a plurality of check valves 241 respectively mounted 20 between the filter tanks 44 and the pumps 400 to prohibit a reverse flow of water, a water accumulator 492 connected to the filter tanks 44 to collect filtered water, and a water tank 493 connected to the water accumulator 492. The power machines 4 are reciprocating 25 mechanisms 40 submerged in the sea. Each reciprocating mechanism 40 comprises a casing 42 defining a receiving chamber 41 and a plurality of water inlets 43 in communication with the receiving chamber 41, a movable bumper 45 moved in the receiving chamber 41 5 and adapted to bear the wave pulse of the sea, and a plurality of spring elements 46 mounted inside the casing 42. Each pump 400 comprises a pressure chamber 421 mounted inside the casing 42 of the corresponding reciprocating mechanism 40 and disposed in 10 communication with the corresponding filter tank 44, a water passage 422 disposed in communication with the pressure chamber 421 and the water inlets 43 of the corresponding reciprocating mechanism 40, an one-way valve 423 mounted in the water passage 422 to let water lS flow from the water inlets 43 to the pressure chamber 421 and to prohibit a reverse flow of water (see the dotted line shown in Figure 5), and a piston 424 connected to the movable bumper 45 and moved with it in the pressure chamber 421. The receiving chamber 41 of the casing 42 20 has a plurality of sliding grooves 425. The movable bumper 45 is supported on the spring elements 46 and mounted with a plurality of rollers 451 adapted to move in the sliding grooves 425. The spring elements 46 impart an outward pressure to the movable bumper 45, causing 25 the movable bumper 45 to be forced against the tide of the sea. Further, a meshed guard 47 is covered around each power machine 4 to prevent fishes and other objects from passing to the inside of each power machine 4.
Referring to Figures 4 and 5 again, 5 when the water of the sea enters the receiving chamber 41 through the water inlets 43, it flows into the pressure chamber 421 through the water passage 422, causing the pressure chamber 421 to be filled up with water, at the same time the movable bumper 45 is pushed to the front 10 side of the receiving chamber 41 by the spring force of the spring elements 46. When the tide of the sea beats the movable bumper 45 (see the imaginary lines shown in Figure 4), the movable bumper 45 is moved backwards to compress the spring elements 46 and to force water out of 15 the water inlets 43, and at the same time the piston 424 is moved backwards into the pressure chamber 421 to force water out of the pressure chamber 421 into the corresponding water delivery pipe 48. When water is forced into each water delivery pipe 48, it is accumulated 20 therein and stopped from flowing backwards by the respective check valve 241. When the tide of the sea falls, the movable bumper 45 is immediately pushed the front side of the receiving chamber 41 by the spring elements 46 (see the real line shown in Figure 4), 25 permitting water to flow to the inside of the receiving 1 o chamber 41 through the water inlets 43. Therefore, when the tide of the sea rises and falls, water is continuously pumped to the filter tanks 44 through the water delivery pipes 48 by the pumps 400 of the power machines 4.
