Definitions
- the present invention relates to a device according to claim 1 and a ner driving according to claim 6.
- the present invention is therefore based on the object of specifying a device and a method for generating electricity from water waves which can generate energy directly from the water wave without generating water flow.
- the device according to the invention for generating electrical energy from surface waves of a water surface comprises a device for converting mechanical energy into electrical energy, a device for converting compressed air fluctuations into mechanical energy and a device for converting surface waves into compressed air fluctuations.
- Surface waves are understood to be the waves occurring on the surface of the water surface.
- the device for converting mechanical energy into electrical energy is in particular an electrical generator such as a synchronous machine or the like.
- the device for converting compressed air fluctuations into mechanical energy sets pressure fluctuations in a gas, for example the air, into mechanical work. Preferred is a piston and turbo machine.
- the device for converting surface waves into compressed air fluctuations is preferably a pipe which extends from a base point located outside and above the water surface to an end point located below the water surface.
- the tube preferably extends in a funnel shape from the base point to the end point.
- a compressed air reservoir can be arranged between the tube and the device for converting compressed air fluctuations into mechanical energy.
- the device according to the invention preferably forms a closed mobile unit. For example, this can be loaded onto a vehicle in the manner of a container.
- the method for generating energy it is provided that initially wave-shaped fluctuations in the water level of a water surface are converted into compressed air fluctuations and the compressed air fluctuations are fed to a device for converting the compressed air fluctuations into mechanical energy.
- the method for generating energy is preferably carried out using a device according to one of the preceding claims.
- Fig. 1 is a schematic diagram of a device according to the invention.
- the device according to the invention comprises a tube 1, which extends from a base point 6, which is located outside and above a water surface 11, in the direction of the water surface 11 and dips into this to an end point 10 below the water surface.
- the pipe cross section at the end point 10 of the pipe 1 is at least partially immersed in the water. From the base point 6 to the end point 10, the tube 1 is funnel-shaped, so the cross section increases from the base point 6 to the end point 10.
- the tube 1 represents a device for converting surface waves into compressed air fluctuations.
- the base point 6 is with a detachable connection 7 attached to the bank 9.
- a compressed air line 2 connects the base end of the tube 1 with one Compressed air tank 5.
- the compressed air tank 5 is connected via a further compressed air line 2 'to a device for converting compressed air fluctuations into mechanical energy, a compressed air motor 3.
- the air motor 3 can be a piston machine or a turbo machine. Air flows through the compressed air motor 3, the flowing gas being expanded and mechanical energy being generated in the process, which is converted in a generator 4 as a device for converting mechanical energy into electrical energy into electrical energy.
- waves 8 of the water surface reach the tube 1, they cause pressure fluctuations in the air contained in the tube 1 by increasing or decreasing the water level. The pressure fluctuations are converted into electrical energy by the compressed air motor 3 and the generator 4.
- the device shown above is designed as a water wave power plant in such a way that it can be handled as a complete unit, in a mobile and transportable manner, and can therefore be used in any conceivable coastal or water region.
- At least one pipe or channel 1 is brought into position so as to move to the incoming water wave 8 such that the
- Pipe 1 like a collecting container, absorbs part of the approaching water wave 8 and the air, which is previously in this tube 1 or channel 1, is compressed in this tube 1 by the inflowing water force of the shaft 8.
- This compressed air thus generated and compressed by the pressure of the force of the water wave 8 is now led at the end of this tube 1 directly to at least one compressed air storage tank 5 via at least one movably attached compressed air line 2.
- the compressed air generated is released via at least one compressed air line 2 to at least one compressed air motor 3 and is used here as
- the compressed air generated in the tube 1 can also optionally be sent directly to the compressed air motor via a compressed air line 2, bypassing the compressed air storage tank 5
