Technical Seid;

Pressurized gas powered hydroelectric generator is a portable hydroelectric power plant that provides with a continuous supply of green electricity from a water cycle with the power of pressurized gas similar to that of a water rocket .

There are many hydroelectric plant available for generation of electricity but none are portable or provide with continuous supply of electricity.

Unlike the regular hydroelectric power plant that's draws energy from the water head ( or other hydroelectric forms ) ,and also there available compressed air storage generator. There is no such power plant available integrating both to provide with a continuous supply of green energy.

Since there is no such system available to provide a continuous supply, the need for such a power plant is vital , This is the most cost efficient and the portable for the generation of the electricity.

The power plant is a potable mode of arrangement of given elements. The power plant consists of a closed pressurized container, where the liquid is filled to the bottom, and followed by pressurized gas very similar to a water rocket. A pipe or hose feds the liquid from the closed pressurized container to hydroelectric turbine system (hydraulic turbine system) where stop valve or control valve can be used to control the liquid flow to the hydroelectric turbine .The potential energy of the pressurized gas develops liquid jet that rotates the hydroelectric turbine. The hydroelectric turbine is connected to an electric generator and a pressure pump (hydraulic or any other) for transfer of rotational energy (where both are firmly placed) .

[0003]

The arrangement is done in such a way that the liquid is felled to storage tank after striking hydro turbine system, where the storage tank already has some amount same liquid pre stored. The rotational energy of the coupled electric generator provides with the continuous supply of electricity and this is taken out for the use. While the coupled pressure pump pumps back the liquid form the storage tank to the pressurized sealed container through suitable pipe or hose as with a specific calculated flow and pressure. The pumped liquids pressure is more than that of the pressure inside the pressurized sealed container, and a check valve connected to the hose or pipe as it enters pressurized closed container regulates the flow only towards the closed pressurized container.

[0004]

There may use an flow control valve attached to the pumped liquid flowing hose (or pump with inbuilt flow control valve) ,that regulates the flow of the pumped liquid to match same or more than the liquid flow to the hydroelectric turbine for the cyclic flow. The perfect adjustment for the cyclic flow is done by a gate valve actuator that releases the liquid to the storage tank when the liquid is shot above the given level inside the pressurized closed container.

Water rocket equations and other basic fluid mechanic equations are basically used for the calculations. Using denser liquid can increase the efficiency of the given system and also in the case of water increasing density by adding suitable impurity to increase density can have a good effect increasing the overall horse of the system.

[0005]

There relief valve is also used to regulates the given pressure inside the pressurized closed container.

Detailed description of tie preferred embodiments:

In reference to figure 1 :

[0006]

Power plant comprising of a pressurized closed container 1, where liquid 6 and pressurized gas 3 is filled as per calculation similar to that of water rocket .The size and shape of the pressurized sealed container 1 does not limit the scope of invention .The potential energy of pressurized air 3 is transferred to liquid 6 , where the liquid 6 provide rotational kinetic energy to hydroelectric turbine ( or hydraulic turbine which include the all systems of a turbine) 14 by means of liquid jet or (reaction mass). Liquid 6 is fed to the hydroelectric turbine 14 through a pipe 26, where the flow of liquid 6 is controlled by a control valve (or stop valve) 15.

[0007]

The shaft 13 of the hydroelectric turbine 14 is coupled 12 to the to pressure pump 16 (or any other sorts of liquid turbine and other devices that can provide with liquid pressure) and to an electric generator 8, where the coupling 12 is placed with suitable bearing and gearing as per the calculation. When the liquid 6 jet strikes the hydroelectric turbine 14, The shaft 13 transfers the rotational energy to electric generator 8 and pressure pump 16.Electric connection 9 from the electric generator 8 is taken out for electric needs .The type, location and number of hydroelectric turbine 14 - pressure pump 16 - electric generator 8, and the does not limit the scope of invention, when placed with suitable calculation.

[0008]

The arrangement is done in such a way that after striking the hydroelectric turbine 14 the liquid 6 is felled to the storage tank 7 where it forms the stored liquid 10 (where some amount of the same liquid is already kept). The stands 11 pressure pump 16, electric generator 8, and the hydro turbine system 14 is equipped suitable bearings and arrangements that does not resist the transfer of energy and the stand 11 should hold the three 16,14,8 above the stored liquid 10 level in the storage tank ( for the given fig 1 arrangement) .The pressure pump 16 pumps the stored liquid 10 to the pressurized closed container 1, where pressure of the pumped liquid 21 is more than that of the pressure inside the pressurized closed container 1. The pressure pump 16 sucks the stored liquid 10, through the suction pipe (or hose) 17, and pumps the more amount of pressure liquid 20 through pipe (or hose) 18 to the pressurized closed container 1 than the liquid 6 flow towards the hydroelectric turbine 14.

[0009]

The pumped pressure liquid 20 is met with an optional flow regulator valve 19, to exactly or closely matches the flow of pressure liquid 2© to the flow of liquid 6 to the hydro turbine system 14, for a cyclic flow. There is a check valve 27 connected to the pipe 18 where it feds pressure liquid 2© to the pressurized closed container 1. The check valve 27 restrict the backward flow of liquid 6 for a cyclic process, and also during filling of liquid 6 and pressurized gas 3 before opening the control valve 15 to the hydroelectric turbine 14. A liquid level sensor 24, gate valve actuator 22 with suitable mechanical and electrical connection 23, is also attached for fine adjustments for cyclic flow process, as the gate valve actuator 22 release the liquid 6 to the storage tank 7 , when liquid 6 shoots above the given level in the pressurized closed container 1.

[0010]

The bend pipe 21 release the liquid back to the storage tank 7 when gate valve actuator 22 is activated. The storage tank 7 and the pressurized sealed container 1 and everything are halted firmly and it's not shown in the figure .Lid 29 is optional that protect all of the system from the environment. The size, shape of the pressurized closed container 1, storage tank 7 does not limit the scope of the invention.

In the pressurized sealed container 1, there is liquid inlet valve 5, gas inlet valve 4 and the gas relief valve 2 is attached.

[0011]

The gas relief valve 2 maintains the pressure inside pressurized closed container 1, as the bubbling from the pressure pump 16 could add extra pressure. The flow of liquid 6 from the pressurized sealed container 1 to the hydro turbine system 14 is shown by the arrow named 25, and the flow of the pumped pressure liquid 20 is shown by the arrow 28. The pipe ( or hose ) 18 connection to the closed pressurized container 1 and the all the pipe connections such as 26 are sealed firmly. In reference to figure 2:

[0012]

The liquid flow from the closed pressure container 1 to the hydroelectric turbine 14, from where the liquid is filled to the storage tank 7 and the pressure pump 16 fed the liquid back to the pressurized closed container 1, and the cyclic process continuous.

In reference to figure 3 :

The flow starts from pressurized closed container 1, to the control valve (or stop valve) 15 that regulates flow, and the liquid is fed to the hydroelectric turbine system 14, and fells to the storage tank 7 .Then pressure pumps 16 takes action and pump liquid towards the pressurized closed container 1, liquid met with the flow regulator valve 19. Finally check valve 27 controls the liquid flow from the pressure pump 16 towards the pressurized closed container 1 in a single flow direction.
