ABSTRACTThis project harvests energy from speed breaker by making gear arrangement and usingelectronic gadgets. Large amounts amount of electricity can be generated saving lot ofMoney. And if implemented will be very beneficial for Government. When vehicle is inmotion it produces various forms of energy like, due to friction between vehicle’s wheeland road i.e. rough surface HEAT Energy is produced, also when vehicle traveling at highspeed strikes the wind. The principle involved is POTENTIAL ENERGY TO ELECTRICALENERGY CONVERSION. There is a system to generate power by converting the potentialenergy generated by a vehicle going up on a speed breaker into kinetic energy. Whenthe vehicle moves over the inclined plates, it gains height resulting in increase inpotential energy, which is wasted in a conventional rumble strip. When the breakercomes down, they crank a lever fitted to a ratchet-wheel type mechanism (a angularmotion converter) which in turn rotates a geared shaft loaded with recoil springs. Theoutput of this shaft is coupled to a dynamo to convert kinetic energy into electricity.INTRODUCTIONIn this model we show that how we can generate a voltage from the busy traffic.Conversion of the mechanical energy into electrical energy is widely used concept. It’s amechanism to generate power by converting the potential energy generated by avehicle going up on a speed breaker into rotational energy. We have used that simpleconcept to the project. We connect one mechanical rod with the dynamo and fit this rodon the surface of the road. When any vehicle moves from this roller then due to friction,vehicle Rotate the rod or roller and roller then move the dynamo. When dynamo movethen it generates a voltage and this voltage now connects to the bulbs. In actual practicewith the help of this voltage we will charge the battery and then we use this voltage tolight the small bulb. If we install this unit to the any small flyover then with the help ofthis voltage we generate a small voltage, and with the help of this voltage we light thebulb.The second part of that project is an efficient use of energy by using simple electronics.We always see that road light continuously glow whether vehicle on path or not. Wehave introduced a concept to avoid a waste of light. We have used two sensors betweensome distances. When vehicle pass through first sensor it sends the signal to the
microcontroller that the vehicle is passing along that particular distance then light willglow for that particular time and when vehicle goes out from the second sensor 2Then the second sensor sends a signal to a microcontroller that vehicle has been passedthrough that particular path then light gets off automatically. Different types of basicelectronics components has been used to get the desired output like capacitor, resisteretc. We have also used a light diode resistance(LDR) when LDR senses a light around itall the road lights gets off and when LDR senses there is a dark around it then LDR sendsa signal to microcontroller then all the road lights gets on. By using a LDR we can avoid awaste of light that glow in a day time. The two sensors are made from the concept ofelectronics. These sensors are called an infrared sensor which is made from photo diodeand light emitting diode each. When any vehicle pass from first sensor then first sensorbecomes on, for that time the road lights gets on and when it pass from second sensorthe second sensor become on and the first sensor gets off then the road light gets off.CONSTRUCTION DETAILS:The various machine elements used in the construction of power hump are RACK SPUR GEAR BEARINGS SHAFT SPRINGS ELECTRIC DYNAMOWORKING PRINCIPLE:While moving, the vehicles possess some kinetic energy and it is being wasted. Thiskinetic energy can be utilized to produce power by using a special arrangement calledPOWER HUMP. It is an Electro-Mechanical unit. It utilizes both mechanical technologiesand electrical techniques for the power generation and its storage. POWERHUMP is adome like device likely to be speed breaker. Whenever the vehicle is allowed to passover the dome it gets pressed downwards then the springs are attached to the domeare compressed and the rack which is attached to the bottom of the dome movesdownward 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 twogears rotate in opposite direction. A flywheel ismounted on the shaft whose function isto regulate the fluctuation in the energy and tomake the energy uniform. So that theshafts will rotate with certain R.P.M. these shaftsare connected through a belt drive tothe dynamos, which converts the mechanical energyinto electrical energy. Theconversion will be proportional to traffic density.Whenever an armature rotates between the magnetic fields of south and northpoles, anE.M.F (electro motive force) is induced in it. So, for inducing the E.M.Farmature coil hasto rotate, for rotating this armature it is connected to a long shaft. Byrotating samee.m.f, is induced, for this rotation kinetic energy of moving vehicles isutilized. The poweris generated in both the directions; to convert this power into one waya specialcomponent is used called zenor diode for continuous supply. All this mechanismcan behoused under the dome, like speed breaker, which is called HUMP. The electricaloutputcan be improved by arranging these POWER HUMPS in series. This generatedpower canbe amplified and stored by using different electrical devicesSCOPE AND USES: Low Budget electricity production Less floor area No obstruction to traffic Easy maintenance Suitable at parking of multiplexes, malls, toll booths, signals, etc. Uses: Charging batteries and using them to light up the streets, etc.DISADVANTAGES: Selecting suitable generator. Selection of springs. Achieving proper balance of speed and torque. It gives low electric output
CONCLUSIONIt is anon-conventional type of producing the energy. The existing source of energy suchas coal, oil etc. may not be adequate to meet the ever increasing energy demands.These conventional sources of energy are also depleting and may be exhausted at theend of the century or beginning of the next century. Consequently sincere and untiringefforts shall have to be made by engineers in exploring the possibilities of harnessingenergy from several non-conventional energy sources. This project is a one step to pathof that way. The overall goal was to design the speed breaker System while keeping theengineering, producer and customer models in check. The reason why this feature wasused more than all of the other features are because the other features would not haveas much effect on the complete system. By changing the size and desirable price, weightand capacity can be realized.Future work would consist of a redesign of this model to see exactly how much data wemay be missing with the assumption that we made with low price, weight and capacity.Despite all the assumptions, we still have realized that this product can be verymarketable and that the demand is extremely large which means this is a viable designthat will yield a high return on an investment.
