Abstract

A device for obtaining energy from moving water comprises a pair of turbines 16 arranged in a ‘V’ formation. Each turbine comprises a shaft 12 with one or more helical blades 11. A wall 16 is placed in the inside of the ‘V’ formation to contain the water within the workings of the turbine. The device may be used above the water, at the surface or below the water level. Two devices may be placed together in a diamond formation (fig 6) to use tidal power in both directions. The device may be anchored in place or filled with ballast to hold it in position under the water. The device may also use the wind as a driving force.

Description

A CONVERTOR FOR OBTAINING ENERGY FROM MOVING WATER
This invention relates to a device that will convert the energy contained in moving water into usable energy.
It has been stated that we need to obtain more energy from renewable sources to avoid excessive global warming.
A vast amount of energy is contained in sea waves, tidal currents and flowing rivers. These sources of energy are mainly untapped as most devices that have been tried are not cost effective.
According to this invention there is a means of extracting energy from moving water by using a device based on the Archimedes Screw. The device has a pair of turbines placed in a v-shape in which each turbine comprises a shaft with one or more helical blades attached to the shaft. A wall is placed on the insides of the v-shape to contain the moving water within the workings of the turbine. As the water impacts on the blades of the turbine the shaft of each turbine is caused to rotate along with an axle that is connected directly or indirectly to an electric generator.
A specific embodiment of the invention will now be described with the aid of the accompanying drawings in which:-Figure 1 shows a plan view of the convertor.
Figure 2 shows a section through the convertor for use below water level.
Figure 3 shows a side view of the convertor.
Figure 4 shows a plan view of the convertor for use above sea level.
Figure 5 shows a section through the convertor for use above sea level. Figure 6 shows two convertors for use in a tidal application.
Referring to the drawing Figs 1, land 3 shows the convertor comprising a pair of turbines with each turbine containing a shaft 12 with one or more helical blades 11 fitted around the shaft. The pitch of the blade and number of blades may vary to suit the application. The turbines are placed in a v-shaped formation (see Fig 1) so that more of the convertor is exposed to the incoming water. A wall 16 is placed behind each turbine at an appropriate distance from the blade, to keep the flowing water within the workings of the turbine. At the front of the turbine a shaped head piece 17 deflects incoming water 20 into the workings of the turbine. As the incoming water 20 impacts 21(see Fig 3) on a blade 11 the shaft 12 is caused to rotate 18 (see Fig 2) which in turn rotates with an axle 13 that transfers energy, mechanically or hydraulically, to an electric generator 29.
Upon trials of the convertor it may be for safety and efficiency reasons for the rotation of the turbines to be made to work in the reverse direction.
For using the convertor in flowing water such as river flow, tidal flow, ocean or sea currents the convertor will be placed under the water 27 (see Fig 2) at the desired depth and anchored to the waters bed 33 or fixed to a static object.
The members that form the walls 16 of the convertor can be used to float the convertor to its final location and then be filled with enough ballast to lower the convertor into position.
The convertor can also be used to capture energy from the sea waves by placing it as shown above sea level 27 (see Figs) by using buoyant floating members 31and 22.
The convertor can also be used partly below sea level by having the shafts 12 of the turbines buoyant together with buoyant walls 21 so the convertor floats on the water. An additional buoyant float 31 can be added to gain more buoyancy and stability.
The head piece 32 of the floating members 12,31 and the front piece of the convertor 17 can be streamlined and shaped to push the convertor downwards when a wave strikes the convertor.
The converter can be anchored to the seabed with a line 19 or fixed to a static object both of which will have a connection to allow the convertor to naturally orientate itself to face the incoming waves.
To have a continuous energy transfer it would desirable to capture one wave straight after another. To accomplice this the convertor can include more than one turbine to each side of the convertors v-shaped formation, and if each turbine was supported to work independently this will reduce any blade, when under water, slowing the turbine down when not being impacted by a wave.
In stormy weather conditions the effective length of struts 30 may be adjusted to prevent damage to the convertor. This can be achieved by the tension in line 34 being overcome by the force of water pushing the turbines together to reduce the angle 23. The line 34 can be connected to a float 31 that Is supporting the struts.
An electric generator 28 can be fitted to the front of the shaft 12 as in Fig 4 or incorporated in the head piece 17 as in Figl of the turbine or fitted between the convertors as in Fig 6.
The convertor when used above water level may also capture the energy from the wind.
If the device is used for tidal flow an extra convertor can be added to form a diamond shape as shown in Fig 6. so that it captures the flow in both directions. The direction of rotation of some of the turbines will be in the opposite direction but still capable of capturing energy.
