Description
1 Description ROOF VENT TURBINE GENERATOR Wind operated generators are broadly old and well known, but it has been only utilized in the rural and outback areas. There is clearly a need for alternative energy in the urban or developed areas where the conventional wind generators are not practical or permitted due to their size, noise, space needed or being an eye sore. My invention is a simple, affordable addition to what is available to urban built up area (which is solar and grid power) and can be unnoticeable on the roof of most dwellings. It can be easily adapted to existing commercially available roof ventilating turbines. My invention relates to a dual purpose wind operated, roof mounted turbine with its primary function of ventilating and extraction of the hot air from the roof space, and secondary purpose is generating power, utilizing the wind energy from outside, and the energy from the airflow of the rising heat from inside the roof space. These wind energy's forces exhorted to the blades, rotate the turbine and the vertical shaft, which also rotates the rotor that is fixed to the rotating support arm. As the rotor rotates the magnets attached to it, creates a magnetic field that cuts through the windings on the stator that is attached to the fixed non rotating support arm, producing electrical current. The design of the generator is concentric in the shape of a ring, with an open center to allow air flow through from the roof space. The invention may be better understood with reference to the illustration of examples of the invention which: Figure 1 is a side elevation view of roof vent generator, showing major parts. Figure 2 is a bottom view of the roof vent generator, also showing major parts. Figure 3 is a bottom view of the rotor fixed to the rotating support arm with button magnets. Figure 4 Is a top view of the stator fixed to the stationary support arm, showing the layout of the coils and the baring embedded in the center of the support arm. Figure 5 is a cross sectional view of the generator, showing the rotor and stator components and they relation to each other. Figure 6 is across sectional view if the alternative mode of the generator with dual rotors, which can increase the power output 3 fold. Figure 7 is an alternative mode of increasing the width of the turbine blade. In my invention the roof vent turbine generator is dual purpose as shown in Figurel a turbine 10 supported on varipitch 14 which is fixed to the roof. Rising hot air from the roof space escapes through the center and around the permanent magnet generator 30 and out 2 2 the turbine blades 11, forcing the turbine 10 to turn, adding more force to the blades 11 by the outside wind increases the rotating speed of the turbine 10 to a usable energy. Best material for the turbine 10 is aluminium, it's reasonably strong and easy to work with, plastic is acceptable, but steel needs to be avoided. Rotating components of the turbine as seen on Figure 3 the Blades 11, vertical shaft 12, the rotating support arm 17 and the rotor 31 are all fixed together and rotate together as one unit at the same speed. The generator 30 as can be seen on Figure 3 and 4 is formed by two parts, a rotor 31 and the stator 35 and is designed in a shape of a ring, with an open center, to allow air flowing through it. The width of the generator 30 needs to be as narrow as possible, to allow maximum air flow. Construction of the rotor is shown in figure 3 and 5 the ferromagnetic back iron, typically a steel ring 32 is in contact with the neodymium magnets 34 by magnetic attraction. Other type of magnets with a strong magnetic field may be used. The non-conductive ring 33 can be of any material that is non-conductive and not flexible, with holes drilled in equal spaces and size to fit the magnets 34N, 34S and hold them in place. This non-conductive ring 33 can be omitted if required, then the magnets 34N, 34S needs to be glued to the steel ring 32 to keep them from moving, and the steel ring 32 need to be thick enough not to flax. The neodymium magnets 34N, 34S are placed in place in sequence with opposite polarities, example north polarity up next one south polarity up, this will create a pulsating magnetic affect when rotating. The stator assembly 35, shown in Figure 4 and 5 a coil support ring 37 of a nonconductive and not flexible material such as fibro glass or plastic. With the coils 36 evenly spaced around with the wider end to the outside and fixed with glue to the support ring 37 the whole assembly is then fastened to the stationary support arm 16 with three stainless steel screws. When winding the coils 36 care must to be taken that they are all wound in the same direction, and achieve a consistently same thickness (height) as close tolerances are needed between the magnets 34 and the face of the coils 36 typically from 1 to 3 mm, for gaining better induction. This best achieved by placing the completely assembled stator 35 into a specially designed form, and completely covering the assembly in resin suitable for windings, compressing it from the top evenly until the resin cures or dries. The same process could be done with individual coils 36 if preferred. An alternative configuration of the generator 30 shown in Figure 6 where the stator 35 is located in the magnetic air gap between two rotor parts 31. The two rotors 31 are aligned in such a way that the magnetic poles on each magnet 34N and 34S are opposite to each other between the two rotors 31. As an example a magnetic pole north, on each magnet 34N on one rotor 31 is directly in line with the magnetic pole south on each magnet 34S on the other rotor 31. The magnetic air space between the two rotors 31 is defined by the spacer 39 in the center of the two rotating support arm 17. In this configuration the stator 35 is positioned between the magnetic air gaps, and directly fastened to the stationary support ring 13 in Figurel of the Turbine. This configuration can increase the output power three fold. Wiring the coils 36 for three phase star connection is by joining the ending wire of the first coil 36 to the starting wire of the third coil 36, and so on. When done there will be three coils 36 left 3 with ending wires these are joined together, and there will be three coils 36 left with 3 Starting wires, this three wires are the three live phases 38 A, B, C producing alternating current. Assembling all together is by pushing the vertical shaft 12 in Figure 1 through the baring 18 at the center of stationary support arm 35 seen in Figure 4 and tightening the nut. The three wires ABC are then connected to a suitable rectifier for converting AC to DC that can be used for charging a battery or a set of batteries. Batteries can be a choice of a 3.6 volt, 6 volt or 12 volt, a 3.6 volt battery will be charging almost constantly as it requires slower rotation of the turbine 10, for charging a 12 volt battery the turbine needs to reach a higher speed before charging starts. My invention the "roof vent turbine generator" is ideal for running LED lights such as night light, garden light, path lighting. A commercially available turbine may be improved, to catch more wind and increase the turbine speed, by increasing the width of each turbine blade 11, by attaching a thin aluminium sheet cut to a leaf shape 41 as shown in Figure 7 curved to match the turbine blade 11 shape and fastening it with two pop rivets.
