Electricity is generated by replacing traditional speed switches with some simple mechanism. As the vehicles pass over the speed switches, the rollers that are connected to a generator turn, which in turn generate electricity. This method is an effective way to produce electricity as the number of vehicles on the road are increasing. Also the cost of manufacturing the model is low. It can be placed effectively near traffic lights, in the entrance of parking lots and in any other place where the density of traffic is high. The rollers are fixed on a wooden ramp in which the vehicle passes. When the vehicle passes over it, it begins to move. There is provided a chain drive mechanism which transfers the motion to a DC motor / generator for the generation of electricity. This method provides an efficient way to generate electricity from the kinetic energy of moving vehicles on highways, highways, car parks, etc.
The increasing demand for electricity and the limited supply of fuel demand the need for alternative sources of energy. Through this project, we show a method to illuminate the street lights and the suburbs near roads by extracting the energy of impulse in the speed stops of the automobiles.
This mechanism converts the pulse energy produced by the passage of the vehicle on a stroke of speed in the linear movement of the rack, attached to the speed switch, which drives a pinion mounted on the shaft with the aid of a one-way bearing. The shaft rotates only in the blocking direction of the bearing, which in turn rotates the pulley mounted thereon. Recovery springs push back the speed switches to their steady state. The pulley drives the alternator rotor through a V-belt. The alternator used is a low-inertia composite alternator, ie it requires batteries to generate field current. The batteries are connected to the alternator, which are charged when the alternator rotor rotates.
Data from the experiments show that about 8 volts are generated when a vehicle moves over the speed switches at a speed of 10kmph. The voltage generated decreases as speed increases and vehicle weight decreases. Taking into account that the average Indian traffic density is 18 vehicles / km (reference The World Bank), excluding two wheels, moving with a speed of 5 m / s on the speed switch. 5MWh of power can be produced in a year of a 200 mt stretch. Of the speed switches. This number is required to increase twice if we consider the two wheels.
