So, this is our small step to try to improve this situation by our project. First of all what does electricity mean to us??? Electricity- secondary source of energy i.e. converted from other sources. We need it for every small thing, still notice it’s importance only during load shedding. OBJECTIVES: : OBJECTIVES: “Shaping Imagination” “Electricity”-Need of the hour Scope, Merits and Uses : Scope, Merits 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. BASIC PRINCIPLE: : BASIC PRINCIPLE: Simple energy conversion from Mechanical to Electrical. To generate electricity using the vehicle weight (potential energy) as input Possible using 3 different mechanisms: Crank-shaft mechanism Roller mechanism Rack- Pinion mechanism Why Rack- Pinion mechanism?? : Why Rack- Pinion 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. Slide 7: Roller mechanism has some different disadvantages. Maintenance will be very difficult Might cause collision. Slide 8: What we did??? Rack-Pinion assembly gives good mounting convenience Maximum gear losses– 3 to 5% Efficiency– 95% Construction of generator: : Construction of generator: Initial experiments- DC motor as Generator How is electricity generated??? Basic principle of generation of electricity. What we did??? Challenges we faced!! : Challenges we faced!! Selecting suitable generator. Selection of springs. Achieving proper balance of speed and torque. What we achieved??? : What we achieved??? We LEARNT a lot. Constructed our own generator by applying the basic principle. Although we got less electrical output, we have successfully explained our idea of generating electricity from speed breaker. Future Scope: : Future Scope: Such speed breakers can be designed for heavy vehicles, thus increasing input torque and ultimately output of generator. More suitable and compact mechanisms to enhance efficiency. Slide 13: THANKYOU You do not have the permission to view this presentation.
