The invention described here has the same concept, to exploit the kinetic energy of the wind created by the vehicle when it moves from a point of origin to another point of destination. The invention will contribute to less fuel consumption in the freight and passenger transport vehicle sector, and, as a result, to less environmental contamination by utilizing clean, free and inexhaustible energy and through the easy implementation in countries interested in the application thereof.

Description

SECONDARY ELECTRICAL GENERATION SYSTEM FOR VEHICLES

TRANSPORT

SCOPE:

The present invention relates to a wind turbine system that uses the kinetic energy of the wind and is capable of producing electricity to be used in the transport of loads and passengers, in the equipment, devices and internal means that use electrical energy to operate, such as also for the utilitarian equipment of the transport vehicle itself.

Users who travel every day to our jobs and vice versa, we are permanently exposed to the interior of these vehicles are at high temperatures in summer and very low temperatures in winter causing great thermal discomfort at the time of entering and staying in them In what the trip lasts. The technique known and used by the means of transport to be able to heat the vehicle internally is the use of air conditioning equipment that allows great quality and climate comfort, as is the use of equipment for heating water or cooling.

However, despite the fact that there are equipment and devices installed inside the means of transport, which work by means of electric power, in practice they are rarely used because, in large part, using them produces a high degree of fuel consumption, placing this overconsumption around 15%. It should be noted that if the windows of the means of transport are open while it is traveling, the normal fuel consumption becomes an overconsumption that is between 20% and 35%, because the aerodynamic design of the vehicle opposing a greater degree of resistance to its displacement.

In fact, the electrical energy used by the means of transport for the internal equipment of the latter is that provided by an electric alternator driven by an internal combustion engine that uses a fuel as an energy medium, so that the greater the load of electrical consumption, higher is the fuel consumption to be able to Maintaining the speed and power of the vehicle and consequently higher are the operational costs for these passenger comfort concepts, be these air conditioning, hot water, chilled water and other means of comfort to the passenger on their trip.

According to what has been described, the technical problem identified is that the means of transport do not use or do not install comfort or other equipment for the benefit of the users due to the higher fuel consumption resulting from providing additional electrical energy that is intended to provide of greater comfort when traveling, different from the fundamental necessity that is the displacement of the vehicle.

We must indicate that the use of internal equipment, devices or elements that provide comfort to the passenger using a hydrocarbon as an energy means to provide it, without a doubt also increases environmental pollution due to the greater burning of fuels in the engine.

The invention described here is the result of the exploration to generate electrical energy without using the energy produced by the internal combustion engine of the vehicle itself, using and transforming the kinetic energy produced by reaction to the movement of the mobile, whose objective is to minimize the consumption of hydrocarbons and, as a consequence, increase the environmental benefit that their use brings in parallel.

Therefore, taking advantage of the kinetic energy provided by the wind is presented as the most feasible, economical and practical to perform in terms of the technologies that currently exist, based on smaller and more efficient wind turbine systems and electric power controllers and safer and more reliable control for functionalities widely known in the environment of the ERNC ^' s, applied here in the use of the kinetic energy that provides the displacement of the vehicle. The idea of the proposed invention arises from the toy called in Chile, Remolino.

In fact, the whirlpool, a toy that we used as children, the one that turned when there was wind, but when there was no we ran to produce the same effect, that is, we moved from one point to another creating the wind to produce its turn. It is in this area that the idea of harnessing the wind energy created by the movement of the vehicle was developed in terms of the fact that the ACTION of the movement of movement produced by the transport causes a REACTION in the opposite direction, in our case, the speed with the that the vehicle moves when moving, is the same speed with which the wind moves against it, thereby producing usable wind energy.

On the other hand, this invention will help to reduce the consumption of fossil fuels in freight and passenger transport vehicles by using clean, free and inexhaustible energy, contributing, in addition, to avoiding the greenhouse effect and acid rain, reducing thus climate change scenario in the process, this being a fundamental concern of all governments and NGO ^'s world. The internal electric energy produced by this System will be referred to here as Secondary Transportation Electric Power, the means of transportation being any vehicle that between its point of origin and destination exists a

displacement and use as an energy medium a hydrocarbon (HxCy) or an Electromotive Force (FEM).

STATE OF THE TECHNIQUE:

In the state of the art it is known that the ways to take advantage of wind energy and produce electrical energy correspond to stationary wind turbines that must wait until there is wind to produce electricity, however, in our invention, the displacement movement that performs The vehicle to move from one place to another is the one that creates the wind to be used as a form of energy. The energy created in this way, called kinetic energy, is used by all the means of wind generation in the world.

In this invention the methodology of harnessing the wind has been changed, that is, the electricity generation does not depend on whether or not there is wind, here, the wind is created from the displacement of the vehicle and the generated electric energy used directly or accumulated in a high performance 12 or 24 volt battery bank.

DETAILED DESCRIPTION OF THE INVENTION:

The Secondary Electrical System for Transportation uses the wind created by reaction to the movement of the vehicle when moving from one place to another.

As shown in Figure 1, the wind, created by the movement of

displacement produces usable kinetic energy which is captured by the rotor blades (1) which transform the kinetic energy provided by the wind into mechanical energy of rotation by means of an axis (2) that is attached to the dynamic brake (3) which will act as a brake in the case of over-speed of the vehicle, also on the axle (2) the electric generator (4) is mounted, which will be responsible for transforming the mechanical rotation energy produced by the rotor blades (1) in electrical energy produced by the generator (4). The electrical energy produced by the generator (4), is alternating current (AC), which will be captured and conducted to the terminals (5) of the generator (4), from which the electrical conductors (6) and (7) leave , corresponding to the phase and neutral respectively, to enter the internal control panel of the means of transport (8) and connecting with the terminals of the Rectifier (9), its positive and negative poles. The rectifier (9) will be responsible for converting alternating current (AC) into direct current (DC), so that it can be stored and subsequently used. The electrical conductors (10) and (11) positive and negative pole of the rectifier (9), connect with the positive and negative pole of the Voltage Regulator (12), which will limit the voltage to be able to charge properly the Battery Bank (15), the electrical conductors (13 and (14) output of the voltage regulator (12) are connected to the terminals of the Battery Bank (15) positive and negative poles respectively. The electrical conductors (6) and (17), leave

of the terminals of the Battery Bank (15) and enter the Continuous Current Distribution panel (18) to connect with the outputs to direct current consumption (19) in 12 or 24 volts, depending on the voltage of the vehicle that is using. On the other hand, the electrical conductors (20 and (21), that leave the terminals of the Battery Bank (15), are connected to the input terminals of the Power Inverter (22), equipment that will be in charge of converting the direct current (DC) that the Bank of

Batteries (15) in alternating current of 220 volts, the electrical conductors (23) and (24) corresponding to the output of the terminals of the Power Inverter (22), enter the AC Distribution Panel (18) to connect with the outputs to alternating current consumption (25) in 220 volts. The dynamic brake assembly (3) and the generator (4) are anchored by bolts to a metal base (26) internal to the wind turbine and this in turn is anchored to a metal base (27), which has bolts of anchorage that are fixed to the metal frame of the means of transport in its upper external front part or, failing that, form part of the body of the vehicle integrating it in the construction design of the latter. A metal casing or gondola (28) perimeter covers the blades (1) of the rotor and inside the shaft (2), the dynamic brake (3), the generator (4) and the terminal block (5) of the generator. Also the rotor blades (1) are protected frontally by the front guard (29) so as to avoid external manipulation in the rotor blades.

The invention consists in providing the means of transport of a wind turbine in its upper frontal part, facing the wind, so as to capture through the wind turbine rotor blades the kinetic energy of the wind produced by the movement movement of the vehicle. The kinetic energy thus captured is transformed into rotating mechanical energy which will eventually be transformed into electrical energy by means of an internal electric alternator that is part of the same wind turbine equipment installed in the vehicle. The electrical energy produced is conducted by means of electrical conductors into the means of transport to be distributed and consumed by the equipment, devices or internal elements that use electrical energy for its operation. The electricity generated may be direct current (DC), in 12 or 24 volts, similar to the electric current currently used by cars, buses and trucks, among others, and may also generate electricity in alternating current of 220 volts, using inverter equipment and electrical controllers for this purpose.

Secondary Transportation Electric Power may be used, for example, in air conditioning equipment, water heating equipment, refrigerated water equipment, internal cafeteria of the vehicle, external emergency lighting, internal emergency warning lighting, battery charging, connect computers, charge cell phones ... etc. It can also be used in the means of transporting loads that require refrigeration such as vegetables, fruits and meats, or in terms of road safety. The installation of a wind turbine in cargo transport trucks may be consumed by an air conditioning unit installed internally in the driver's cabin using it as a means to reduce thermal fatigue.

The System may be used in different types of surface and underground transport for the same purpose, reduce the consumption of hydrocarbons, reduce pollution and environmental pollution, and at the same time contribute to the quality and comfort of passengers and drivers travel of means of transport both in winter and in summer.
