GB2469483A - Vertical Axis Wind Turbine - Google Patents

Abstract

Figure 1 shows that the vertical axis wind turbine is a hollow frame with two blades sitting at either end 2, 3, the crests on the blades 4, allow for improved wind capture allowing the unit to rotate faster at lower wind speeds. The central axel 5, transfers this movement into the dual layered dynamo which generates electricity. Figure 2 is an exploded view of the interior of the base unit. Here two static discs each holding a number of coils of magnetic wire 6, 7, are situated either side of a disc 8, holing a number of permanent disc magnets. This disc revolves using the energy delivered to it by the central axel 9.

AC Power Vertical Axis Wind Turbine

Description

This invention relates to a device with the ability to generate high levels of AC power at low revolutions whilst maxirnising the ability to capture wind.

When generating power using wind turbines most designs use a horizontal axis wind turbine. This is not a suitable way of harnessing power when in an urban environment as it requires both high wind speed and a consistent prevailing direction of wind.

The design of the Vertical Axis wind turbine means that it is effective no matter which direction the wind is coming from. The blade design allows for additional capture of wind energy using the ridges on the side and the dynamo design doubles the amount of electricity that can be generated at low wind speeds.

The rotational movement is transferred into the main body of the turbine where the energy is used to turn a set of fixed permanent magnets set between to discs each with a number of coiled magnetic wires around the disc.

This allows the wind turbine to generate AC power which can be used as a domestic energy supply without using inverters or transformers.

The invention will now be explained with reference to accompanying drawings; Figure 1. Shows the entire unit which could be used to generate electricity in urban areas Figure 2. Shows an interior exploded view of the base unit and how the disc of magnets will be situated between the two discs of magnetic wire.

Figure 1, is the wind capture unit which includes two vertically aligned blades to capture wind energy each with crests along the sides to maximise the ability to capture the wind energy. These blades are a placed at either end of a frame which is connected to a central axel. The axel is connected to the base of the turbine which houses the electricity generation unit.

Figure 2. This is an exploded view of the interior of the unit which houses the magnetic wire coils as well as the permanent magnets. Here the movement of the wind turbine will be transferred into the central disc which has the magnets set into it.

This movement rotates the magnetic fields around the wire generating electricity which is then fed into a power supply.
