Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a power generation system, particularly to a gravitation pneumatic buoyant powered generation system. 
       BACKGROUND OF THE INVENTION 
       [0002]    There are many water based energy producing systems. These typically empty turbines and use the forces of flowing water to drive the turbine and generate energy. 
         [0003]    Conventional coal and nuclear power plants generate carbon dioxide which are a problem for the environment. Therefore, much attention is paid to the green energy systems, such as the wind power generation system, hydroelectric power generation system and solar power generation system. 
         [0004]    The green energies are environment-friendly and sustainable. There remains a desire to search for novel green energy sources and to this end the instant invention provides a gravity, pneumatic, buoyant powered wheel generator. 
       SUMMARY OF THE INVENTION 
       [0005]    It is an object to provide a green energy system. 
         [0006]    It is another object to provide a gravitation pneumatic buoyant powered generation, wherein potential energy is converted into kinetic energy to drive a generator to generate electric power when float balls are moved upward from a low position to a high position by buoyant forces. A vertical water tank is provided in which the float balls move back to the high position from the low position to perform a cyclic operation and drive a generator. 
         [0007]    Accordingly, the invention provides a gravitation pneumatic buoyant powered generation system. The gravity pneumatic buoyant aided wheel power generator includes a first vertical tank receiving float balls therein which fall downward due to gravity. A first check valve door is provided which opens under a vacuum to receive the float balls therethrough. An intermediate chamber is provided for receiving the float ball from the first vertical tank through the first check valve door. 
         [0008]    A pneumatic device is communicably connected to the intermediate chamber to cause a pressure differential in the intermediate chamber thereby causing opening and closing of the first check valve door and intake of the float ball upon a negative pressure being applied. A second vertical water tank is communicably connected to the intermediate chamber by way of a second check valve door which is normally closed and opens upon a positive pressure being applied to the intermediate chamber by the pneumatic device thereby releasing the float ball into the second vertical water tank in a manner to rise and engage a fin on a side of a drive wheel which includes a central drive shaft. Positive pressure also closes the first check valve door. The drive wheel has a plurality of outwardly disposed fins each spaced and configured for receiving one float ball and by virtue of air within the float ball impinge force on an adjacent fin causing a rotational drive force on the wheel and in turn rotation of the drive shaft. 
         [0009]    An end of the drive shaft can be splined to a gear mechanism which can include an adjustable crank to increase or decrease stroke of a connecting rod. A bellows or piston connects to the connecting rod for generating the pressure differential in the intermediate chamber. Another end of the drive shaft can be operatively connected to a generator which produces an electrical output upon movement of the drive wheel.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0011]    Referring now to the drawings, the gravitation pneumatic buoyant powered generation system of the present invention is generally designated by the numeral  10 . The gravitation pneumatic buoyant powered generation system  10  provides for potential energy to be converted into kinetic energy to drive a generator to generate electric power when float balls  14  are moved upward from a low position to a high position by buoyant force. The float balls  14  move from the high position from the low position via gravity to perform a cyclic operation. 
         [0012]    Accordingly, the gravity pneumatic buoyant aided wheel power generator includes a first vertical tank  12  receiving float balls  14  therein which fall downward due to gravity and superposed float balls  14 . A check valve door  16  is provided which opens under a pressure differential (vacuum) to receive float balls  14  therethrough. An intermediate chamber  18  is provided for receiving the float balls  14  from the first vertical tank  12  through the check valve door  16 . 
         [0013]    A pneumatic device  20  is communicably connected to the intermediate chamber  18  to cause a pressure differential in the intermediate chamber  18  thereby causing opening and closing of the check valve door  16  and intake of one of the float balls  14  upon a negative pressure being applied. A second vertical water tank  22  is communicably connected to the intermediate chamber  18  by way of a second check valve door  24  which is normally closed and opens upon a positive pressure being applied to the intermediate chamber  18  by the pneumatic device  20  through and intake/exhaust line  21  thereby releasing the float ball  14  into the second vertical tank  22  in a manner to rise and engage one of the fins  26  on a side of a drive wheel  28 . Second check valve door  24  can be equipped with a check valve device  25  to ease lift thereof. The drive wheel  28  includes a central drive shaft  30 . 
         [0014]    The plurality of fins  26  are outwardly disposed and are spaced and configured for receiving one of the float balls  14  as the rise and by virtue of air therein. The float balls  14  impinge force on the fins  26  causing a rotational drive force on the drive wheel  28  and in turn rotate the drive shaft  30 . 
         [0015]    An end  34  of the drive shaft  30  is splined to a gear mechanism  32  which can include an adjustable crank can be employed to increase or decrease stroke of a connecting rod  36 . A bellows or piston  38  connects to the connecting rod  36  for generating the pressure differential in the intermediate chamber  18  and collectively functions as the pneumatic device  20 . Another end  40  of the drive shaft  30  operatively connects to a generator  42  which produces an electrical output upon movement of the drive wheel  28 . 
         [0016]    When the float balls  14  engage the fins  26  the drive wheel  28  rotates clockwise. The generator  42  in turn generates electric power for use or storage. There can be employed a speed-change gear assembly which can increase the rotational speed to enhance the efficiency of power generation. Water levels are depicted by the letter W and W 1 . 
         [0017]    As the specific gravity of the float balls  14  is smaller than that of water, the float balls  14  float and rise to an opening  23  of the vertical water tank  22  spontaneously. There is a chute  27  which feeds float balls  14  to the vertical tank  12 . There is a bleed back line  29  connecting the line  21  and the chute  27  with a operably disposed check valve  31  for fluid level return. The water level W 1  is able to maintained by virtue of the valve door  16  and thus enable drawing in the float ball  14  under pressure of the pneumatic device  38 . Then, the float balls  14  are moved from the low position to the high position once again. The present invention can thus cyclically generate electric power by utilizing buoyant force. 
         [0018]    An automated water supply device (not shown) can be is installed at the opening of the vertical water tank  22  and used to control the water level. A rotary control device (not shown) can also be provided in the chute  27 , for example, to control the number of the float balls  14  delivered and in turn drive the driving wheel  28  to rotate at a constant speed. Thus, stable power output is provided to drive the generator  42  to generate electric power. 
         [0019]    The present invention provides a low cost energy producer. It will be understood by those skilled in the art that modifications, derivations and improvements will be apparent to the claims herewith and should be included within the scope of the claims.
