Abstract

To overcome the disadvantage of limited input tidal flow velocity at approximately 2.5m/s which limits the power output and size of a turbine 8, the power system has a vertical leg 4 in the inlet to the turbine so that the flow to the turbine is augmented by the head pressure of the leg. There is no limitation on the size of the power turbine fitted to the proposed system, unlike existing power turbines. Inflow to the leg 4 is via a flap valve 3. Other stated applications are for wind power and drive to a ship's propeller.

Description

* 2446856 LoJ POJL The object of the present application is to improve
the efficiency and rating of existing tidal flow sub-sea turbines.
This is achieved by fitting to the inlet duct of the turbine the equipment shown in Fig 1.
In this diagram the sea flows at 2.5 m/s entering the opening at I and deflects from the vertical by the flap valve 3 and this conveys the flow down the vertical leg H. The flow being pressurised before entering the turbine inlet duct 8. The flow then courses through the turbine generating power through the process, overcoming dynamic and friction losses therein.
The flow then flows vertically downwards entering the sea.
Further applications are in the marine field where the said system can be mounted on a ship to drive the propeller from the turbine generator.
A further application is as an improved wind power machine mounted ashore or off shore driving the turbo propeller at higher speeds.
Conclusions
The proposed invention and associated applications demonstrate a more effective method of trapping the vast reserves of tidal flow energy around the world. Such extraction of tidal flow energy is unusual by the methods proposed and it is unlikely these methods occur in any other known invention at the present time.

Claims (4)

  1. Claims 1. The tidal flow system proposed generates power automatically
    by the flow being led Into a pressurised vertical log with the contained energy flow entering the turbine and generating power.
  2. 2. A similar system to 1 generating power in a wind turbine located ashore or off shore. a
  3. 3. A marine system designed to drive a ship's propeller thus reducing th. power required from the ship's engines.
  4. 4. Said claims 1-3 if developed world-wide would generate vast amou,tg of power by the said invention, unlikely to be achieved by current forms of renewaWo energy or even by nuclear power.
