1. Field of the Invention
The present invention relates to a generating system and, more particularly, to a water cycle generating system.
2. Description of the Related Art
A conventional generating system comprises a chain, a plurality of catch boards, a large gear and a generator unit. The catch boards are mounted in a water pipe to catch water to increase the water weight to drive the large gear which is rotated to drive the generator unit so as to produce an electric power. However, the generating system has a very complicated construction, thereby greatly increasing its cost of fabrication and causing inconvenience in maintenance.
In accordance with the present invention, there is provided a generating system, comprising a base, a first water storage tank mounted on a lower portion of the base, a water tower mounted on an upper portion of the base, at least one generator unit mounted on the base and disposed between the water tower and the first water storage tank, a penstock unit connected between the water tower and the first water storage tank and passing through the generator unit to introduce water from the water tower through the generator unit into the first water storage tank, and at least one water raising device mounted on a side of the base and connected between the first water storage tank and the water tower to raise water from the first water storage tank to the water tower.
According to the primary advantage of the present invention, the pressure tank produces a high air pressure by the successive pivotal action of the air inlet valve, and the high air pressure in the pressure tank thrusts the water into the water tower so that the water raising device can pump the water from the first water storage tank into the water tower without needing any electric power so as to save the cost largely.
According to another advantage of the present invention, the water raising device pumps the water from the first water storage tank into the water tower, and the water in the water tower initially passes through the generator unit to generate an electric power and then directly falls down into the first water storage tank so that the generating system forms a water cycle to generate an electric power in a cyclic manner.
According to a further advantage of the present invention, the water drained from the water raising device is driven by the water return device and can be returned into the first water storage tank.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

In operation, the air inlet valve 23 is pivoted downward and opened by the gravity of the weight 25 as shown in
In addition, the water flowing out of the air inlet valve 23 is delivered through the water outlet pipe 24 into the second water storage tank 12. Then, the water in the second water storage tank 12 falls down onto the water return pipe 13 to impact the catch plates 46 as shown in
