Abstract
This paper is presenting the study of electricity generation through the speed breaker mechanism.
For obtaining the electricity through the speed breaker mechanism a prototype model is developed and studied.
Findings from this research work are discussed in this paper. The generator used here is permanent magnet D.C.
generator. The generator voltage is 12 Volt D.C. This D.C. voltage is stored to the lead 12-volt battery. The battery is
connected to the inverter. The inverter is used to convert 12 volt D.C. to the 230 volt A.C [3]. Voltage is used to activate
the light fan etc. By increasing the capacity of the battery and the inverter circuit the power rating is increased
INTRODUCTION
Energy is the primary and most universal measure of all kinds of works by human beings and nature.
Everything what happens in the world is the expression of flow of energy in one of its forms. Most people use the
word energy for input to their bodies or to the machines and thus think about crude fuels and electric power.[5]
Energy in the form of electricity plays a very important role in the life of a normal man. Electricity is one of the
greatest wonders of science. Next to man, it is the most important and revolutionary creation in this world of ours
.It has practically revolutionized the world .The gradual but excessive use of electricity has come to bring about a
stupendous changes in industry. With it our modern gigantic tools are worked. Computers as also calculators sum
up totals and make other calculations with the utmost accuracy. Newspapers and books are printed in millions
PRINCIPLE OF WORKING
The principle of the electric power generation using speed breaker mechanism is very simple. It is based on the
same principle as in the case of electricity generation in case of hydroelectric power plant, thermal electric power
plant, nuclear power plant, geothermal energy, wind energy, tidal energy etc. In all of the above power plant
mechanical energy is converted into electrical energy [2]. In this setup also mechanical energy is converted into
electrical power using a D.C. generator. Here the vertical motion of the top of the speed breaker is converted into the
rotational motion, which in turn rotates the generator and generates electricity
CONSTRUCTION
This setup mainly consists of an arrangement which is having a shaft with a U shaped projection carrying a bearing
and is connected to the top of the speed breaker. The bearing is provided in order to permit the relative motion
between the shafts. In this way vertical motion is to be converted into rotational motion. The top of the speed
breaker will be provided with the return spring in order to retain its position after it will be displaced by the weight
of the vehicles in the downward direction. The spring is designed depending on the weight of the vehicles passing
through it. The two ends of the shaft will be fixed with the help bearing. The shaft is made of mild steel. This shaft
will also be provided with the sprocket, as it will rotate in direction of the shaft. This sprocket will be connected
with another sprocket with the help of chain drive, which is mounted on the other shaft this action is like the bicycle
arrangement. The lower shaft also consists of a gear. A gear is also mounted on the generator and is meshing with
gear on the lower shaft this will help to rotate the D.C. generator and in turn will generate electrical power, which
will be stored in the battery and can be used accordingly.
The generator used here is permanent magnet D.C. generator. The generate voltage is 12 Volt D.C. This D.C.
voltage is stored to the lead 12-volt battery. The battery is connected to the inverter. The inverter is used to convert
12 volt D.C. to the 230 volt A.C. voltage is used to activate the light fan etc. By increasing the capacity of the
battery and the inverter circuit the power rating is increased. This arrangement is fitted in highways, the complete
arrangement is kept inside the floor level except the speed brake arrangement
WORKING OF THE MODEL
The working of this speed breaker arrangement for producing electricity is very simple. There are a large number of
automobiles running on the road. These automobiles go over a number of speed breakers present on the road. The
vehicle is having a variety of weight like trucks, buses, cars, and two wheelers therefore whenever they are passing
over a speed breaker a lot of energy is wasted. So when the vehicle will come on the speed breaker because of its
weight the top portion of the speed breaker moves down wards and the shaft consisting of the U portion rotated in a
particular direction. Due to this rotation of the shaft the sprocket will rotate and the rotational energy from one shaft
is transferred to the other shaft with the help of chain drive mechanism. This rotates the gear on the bottom shaft,
which in turn will help to rotate the gear placed on motor. This rotation of the gear starts the generator and generates
electricity which can be stored in the battery and can be converted in a.c. current using inverter and used for lighting
of the lamps, signals sign boards on the road.
On the other hand when the vehicles have passed over the bump the top will retain its position with the help of the
spring provide and the chain drive will rotate in the reverse direction without rotating the gears as in case of the
bicycle where the bicycle moves ahead when force is applied on the pedal. But when the pedal is rotated in the
reversed direction the bicycle moves in the reverse direction. Thus power is generated only during the downward
motion and not in the reversed motion of the top portion of the breaker.
This principle can also be used in the steps of the staircase to produce electricity. In which whenever a person puts
his foot on the step due to his weight the step gets displaced in the down ward direction and will rotate the rotor of
the generator in same manner as in case of speed breaker arrangement. And thus electric power can be generated
which can be used in lightning of the buildings
APPLICATIONS
Power generation using speed breaker system can be used in most of the places such as:
x This technique can be used in all highways.
x This technique can be used in all roadways Speed brake.
This mechanism of generating of electricity can be placed on the actual speed breaker of the roads. The power is
generated when the vehicles pass through it. Which in can be stored in the battery. This power can be used in many
places after using the inverter, which enhances in the voltage from 12 volts to 230 volts. This power can be used in
the following:
x Street Lights.
x Road Signals.
x Sign boards on the roads.
x Lighting Of the bus stops.
x Lighting of the check post on the highways etc
CONCLUSION
This methods have many advantages such as Power generation does not require any fuel input, Running cost is very
less, This is a non-conventional form of energy and therefore very useful in the present scenario of energy crisis. As
coin has two faces in the same way there are also some disadvantages such as Mechanical moving parts is high and
therefore there are very large frictional losses and therefore require more maintenance, Initial cost of this
arrangement is very high. The overall efficiency is quite low as compared to other techniques.
