Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.

[0029] As mentioned above, there is a need for an apparatus for generating power to operate telecommunication networks. The embodiments herein achieve this by providing an apparatus for generating power to operate telecommunication networks using vertical axis wind turbine. Referring now to the drawings, and more particularly to FIGS. 1 through 4.2, where similar reference characters denote corresponding features consistently throughout the figures, there are shown preferred embodiments.

[0030] FIG. 1 illustrates the perspective view of an apparatus 100 for generating power to operate telecommunication networks, according to an embodiment. The apparatus for generating power to operate telecommunication networks using vertical axis wind turbine. The apparatus comprises of, at least one vertical wind turbine, at least one generator 302, a gearbox and at least one Faraday cage 106. The vertical wind turbine (VAWT) may include but is not limited to a hub, a hollow rotating vertical shaft 105 or shaft, a rotor, a plurality of blades 107, and a brake mechanism. The hub is placed above the gearbox attached on to the shaft to which the plurality of blades 107 is attached. The hollow rotating vertical shaft 105 or shaft 105 is connected to the hub that in turn connected to the generator 302. The shaft 105 is mounted on top of the telecommunication network. The shaft 105 is provided to transfer the rotation of blades 107 due to wind energy to the generator 302 and thereby to convert the wind energy to electrical energy. The Faraday cage 106 is wrapped around the generator 302 to avoid electromagnetic interference and lightning.

[0031] According to an embodiment, the hub for VAWT may include upper hub 101 and lower hub 104 to attach the blades 107 at two points of the hollow rotating vertical shaft 105 using upper bearing 102 and lower bearing 103 respectively. The hub is made of materials such as cast iron or cast steel. The rotor is the heart of a wind turbine and consists of multiple blades 107 attached to a hub. The rotor is responsible for collecting the energy present in the wind and transforming this energy into mechanical motion. Further, increase in an overall diameter of the rotor increases the amount of energy that the rotor can extract from the wind. A predetermined rotor diameter is designed to obtain a predetermined energy from the wind.

[0032] According to an embodiment, the Faraday cage 106 is made up of aluminum or copper sheets with a predetermined thickness which depends on the intensity of the radiation emitted in the telecommunication network. The Faraday cage 106 converts incident radiation into current producing equal and opposite electromagnetic field to cancel out an existing electromagnetic field. The apparatus is provided with a battery backup for providing uninterrupted service for the telecommunication network.

[0033] FIG. 2 illustrates blades 200 of Darrieus-type vertical axis wind turbine, according to an embodiment. The blades 107 are a crucial and basic part of the vertical axis wind turbine. The blades 107 of the Darrieus-type vertical axis wind turbine are having curved structure. The blades 107 are made of materials such as aluminum, fiber glass or carbon fiber to provide better strength to weight ratio. The design of the individual blades 107 also affects the overall design of the rotor. The blades 107 can take the energy out of the wind and the blade capture the wind and convert its kinetic energy into the rotation of the hub.

[0034] FIG. 3 illustrates the line diagram of an apparatus 300 for generating power to operate telecommunication networks, according to an embodiment. The line diagram shows the internal components present in the Faraday cage 106. The Faraday cage 106 covers the generator 302, the gearbox 301, and the brake mechanism. The gearbox 301 provided for increasing speed of the hollow rotating vertical shaft 105 thereby to increase the speed of the generator 302. The gearbox 301 is made up of aluminum alloys, stainless steel and cost iron and so on. The gearbox 301 includes plurality of gear stages that comprises planetary type, helical type, parallel shaft type, spur type and worm types. There are two or more gear types combined in multiple stages to achieve required speed.

[0035] According to an embodiment, the brake mechanism is provided on the shaft 105 between the gearbox 301 and the generator 302. The brake mechanism includes a mechanical drum brake or disk brake. The brake mechanism is provided on the shaft 105 between the VAWT and the gearbox 301. The brake mechanism may include but is not limited to a mechanical drum brake, disk brake and so on. The mechanical drum brake or disk brake is use to stop the turbine in emergency situation such as extreme gust events or over speed. This brake is also used to hold the turbine at rest for maintenance as a secondary mean, primarily mean being the rotor lock system.

[0036] According to an embodiment, the generator 302 utilized for the apparatus is three phase induction generator 302. The power output from the generator 302 is for example 10 Kw. In the wind turbine one of the major constraints taken into consideration is varying speed of wind. So, synchronous machines may not work effectively for varying speeds. Hence asynchronous machine is the best available choice and it is also proved that induction generator 302 suits best for variable speeds. However, single-phase induction machines will not work effectively for power ratings as high as 10 Kw. They are used only for low power ratings. Therefore, three-phase induction generator 302 is an ideal machine for a wind turbine of high power ratings. For example, the voltage rating depends on the voltage required by the base station and the current rating depends on the current rating of the base station. The Power rating may be 10 Kw. Further, speed of the generator 302 can be 250-500 RPM.

[0037] FIG. 4.1 illustrates the side view of an overall setup 400a of an apparatus mounted on the telecommunication networks, according to an embodiment. FIG. 4.2 illustrates the perspective view of an overall setup 400b of an apparatus mounted on the telecommunication networks, according to an embodiment. The apparatus is mounted on top of the telecommunication network system 401. The base of the vertical axis wind turbine is usually mounted on the top of a platform on which it is installed. The Faraday cage 106 is provided to protect the generator 302 from electromagnetic interference. Hence the generator 302 placed inside this Faraday cage 106 is free from radiations. And one more added advantage with this Faraday cage 106 is it protects the apparatus from lightning.

[0038] According to an embodiment, the design of the apparatus can increase the efficiency of the turbine. The apparatus allows user to deploy the Darrieus turbines/vertical axis wind turbine in real time environment, to configure and monitor the increase in power generation and efficiency. Further, the apparatus can provide a mechanism for self-starting of the Darrieus turbine which eliminates the requirement of an external energy source to bring the device to a minimum rotational speed. In addition to that, the apparatus can provide a solution to control the maintenance and construction costs. The design of the apparatus may provide solution to many of the problems with respect to cost, maintenance, radiations, powering and noise of the telecommunications tower associated the wind turbines.

[0039] Another object of the present invention is to provide a viable solution for increased power generation to satisfy power requirements in the future world. Further, the apparatus can be installed for telecommunication networks that includes but not limited to cellphone towers, telescopic mast, radio towers, mast towers, cellular towers, EMS service technology towers, navigation towers, television towers, global positioning satellite technology towers, mobile towers, radio signal transmission towers, high rise buildings and so on.
