INTRODUCTION:
An energy crisis is any great bottleneck (or price rise) in the supply of energy resources to an economy. An energy crisis may be referred to as an oil crisis, petroleum crisis, energy shortage, electricity shortage electricity crisis. This project is about GENERATION OF ELECTRICITY with the SPEED BREAKERS. In daily life a lot of energy is lost like the potential energy of vehicles. In this project we are just trying to make use of such energy in order to generate an ELECTRICAL ENERGY. This project will work on the principle of “POTENTIAL ENERGY TO ELECTRICAL ENERGY CONVERSION” Potential energy can be thought of as energy stored within a physical system. This energy can be released or converted into other forms of energy, including kinetic energy and further used to charge a battery and used when needed.
ABSTRACT:
In the present scenario power becomes major need for human life. Due to day-to-day increase in population and lessen of the conventional sources, it becomes necessary that we must depend on non-conventional sources for power generation. While moving, the vehicles posses some kinetic energy and it is being wasted. This kinetic energy can be utilized to produce power by using a special arrangement called “POWER HUMP”.
The Kinetic energy of moving vehicles can be converted into mechanical energy of the shaft through rack and pinion mechanism. This shaft is connected to the electric dynamo and it produces electrical energy proportional to traffic density. This generated power can be regulated by using zenor diode for continuous supply .All this mechanism can be housed under the dome like speed breaker, which is called hump.
The generated power can be used for general purpose like streetlights, traffic signals. The electrical output can be improved by arranging these power humps in series this generated power can be amplified and stored by using different electric devices. The maintenance cost of hump is almost nullified. By adopting this arrangement, we can satisfy the future demands to some extent.
OBJECTIVES:
• To design a low cost machine.
• To utilize a small amount of energy wasted in daily life.
• To reduce cost per unit of power generation.
• To utilize alternate sources of energy.
METHODOLOGY:
While moving, the vehicles possess some kinetic energy and it is being wasted. This kinetic energy can be utilized to produce power by using a special arrangement called POWER HUMP. It is an Electro-Mechanical unit. It utilizes both mechanical technologies and electrical techniques for the power generation and its storage. POWER HUMP is a dome like device likely to be speed breaker.
The 3 different mechanisms proposed are:
-Roller mechanism
-Crank-shaft mechanism
-Rack- Pinion mechanism
Rack and pinion mechanism: This mechanism is most popularly used. This is because of the disadvantages of other mechanisms:
Crank shaft mechanism: Crank-shafts are required to be mounted on bearings which creates balancing problem leading to mechanical vibrations which in turn damage the bearings.Secondly as bearings are of sliding type, any occurrence of variable load( which is bit obvious in case of vehicles!!) leads to balancing problem.
Roller mechanism: Here maintenance will be very difficult and it Might cause collision.
The Rack-Pinion assembly gives good mounting convenience . Te efficiency is 95% with 3-5% gear losses.
Whenever the vehicle is allowed to pass over the dome it gets pressed downwards then the springs are attached to the dome are compressed and the rack which is attached to the bottom of the dome moves downward in reciprocating motion. Since the rack has teeth connected to gears, there exists conversion of reciprocating motion of rack into rotary motion of gears but the two gears rotate in opposite direction. A flywheel is mounted on the shaft whose function is to regulate the fluctuation in the energy and to make the energy uniform. So that the shafts will rotate with certain R.P.M. these shafts are connected through a belt drive to the dynamos, which converts the mechanical energy into electrical energy. The conversion will be proportional to traffic density.
Whenever an armature rotates between the magnetic fields of south and north poles, an E.M.F (electro motive force) is induced in it. So, for inducing the E.M.F.armature coil has to rotate, for rotating this armature it is connected to a long shaft. By rotating same e.m.f, is induced, for this rotation kinetic energy of moving vehicles is utilized. The power is generated in both the directions; to convert this power into one way a special component is used called zenor diode for continuous supply. All this mechanism can be housed under the dome, like speed breaker, which is called HUMP. The electrical output can be improved by arranging these POWER HUMPS in series. This generated power can be amplified and stored by using different electrical devices.
ADVANTAGES:
• The cost of electricity generation and storage per mega watt from speed-breakers will be nearly Rs 1 crore as opposed to about Rs 8 crore in thermal or hydro power stations.
• It utilizes unused energy.
• we can lighten our steeet lamps..
• extra electricity can be send to villages also.
DISADVANTAGES:
• we have to check mechanism from time ot time .
• It will not work with light weight vehicle.
• It can get rusted in rainy season.
