Description

PROPULSION DEVICE POWERED BY WAVE ENERGY FOR POWER PLANT
Background of Relevant Arts or Science
Figure 1 cites Patent No. US 8466575 B2 and discloses inventions related to the propulsion device powered by wave energy for power plants which use wave energy for cylinder propulsion to pump and inject oil to create energy to drive power generators by using wave boards to direct waves and cylinders to work. There is only one wave board and one cylinder resulting in low propulsion. This invention was designed to have two cylinders placed in opposite directions functioning to pump sufficient amounts of oil to the pressure building pipe to enable the hydraulic pump to inject oil to power the power generator. The two cylinders were placed opposite one another to build momentum and centrifugal force. There is an upper weighing tank for building centrifugal force following wave energy, enabling the two cylinders placed opposite one another to switch functions according to wave energy.
In addition, I have also cited my Patent Request No. 1501000815, which has the first buoy installed on the first side to resist wave energy and the second buoy installed on the second side to resist wave energy. The first and second buoys will move according to wave energy and function to propel the wheel. This has a disadvantage in that the propelled wheel is insufficient for generating electricity.

The first part in the first and second cylinders has oil in the first and second cylinders with an exit connected to the first secondary exit pipe and the second cylinder has an exit connected to the second secondary exit pipe. The first secondary exit pipe and the second secondary exit pipe has a supply line connected to the exit pressure pipe. The exit pressure pipe is connected to the hydraulic pump injecting oil to power the power generator. After the oil drives the power generator, the oil is carried to the oil storage tank.

The oil storage tank is connected to the entry pressure pipe and the entry pressure pipe connects the oil supply line to the first secondary entry pipe of the first cylinder and the second secondary entry pipe of the second cylinder to return oil to the first and second cylinders to continue the operation. The first and second cylinders functions to pull oil back into the first and second cylinders .

The first buoy (3 1 ) and the second buoy (32) move according to wave energy and are connected to the structure (10).
5. The propulsion device powered by wave energy for power plants in accordance with claim 1 -4 has the upper structure ( 10) formed as a base to support the weighing tank ( 16). The weighing tank (15) is installed at the center of the structure ( 10) to build momentum and upper centrifugal force to propel the first cylinder (1 1 ) and the second cylinder ( 12) left and right.
6. The propulsion device powered by wave energy for power plants in accordance with claim 1 -5 the structure ( 10) is connected and fastened to a pile driven under the sea to prevent the structure ( 10) from moving with waves. The structure ( 10) holds the first cylinder (1 1 ), first buoy (31 ), second cylinder ( 12) and second buoy (32) to move up and down according to wave energy.
7. The propulsion device powered by wave energy for power plants in accordance with claim 1-6 the structure (10), weighing tank (15), first cylinder (11) and first buoy (31), second cylinder (12) and second buoy (32) form the first power unit (100). There is more than one first power unit (100) installed on the power plant structure (101) floating on the sea.
8. The propulsion device powered by wave energy for power plants in accordance with claim 1-7 has the power plant structure (101) with a number of main buoys (102) functioning to keep the power plant structure (101) a float.
9. The propulsion device powered by wave energy for power plants in accordance with claim 1-8 the top of the power plant structure (101) has a roof (103) for installations, power generating rooms, living quarters, hydraulic pumps (20), power generators (30) and oil storage tanks (40).
