Transcript

  • 1. ELECTRICITY GENERATION FROM SPEED BREAKER
  • 2.
    • Introduction:
    • Is anyone happy with current situation of electricity in India???
    • 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.
  • 3.
    • OBJECTIVES:
    • “ Shaping Imagination”
    • “ Electricity”-Need of the hour
  • 4. 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.
  • 5.
    • BASIC PRINCIPLE:
    • Simple energy conversion from Mechanical to Electrical.
    • To generate electricity using the vehicle weight (potential energy) as input
    • Possible using 3 different mechanism s:
    • Crank-shaft mechanism
    • Roller mechanism
    • Rack- Pinion mechanism
  • 6.
    • 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.
  • 7.
    • Roller mechanism has some different disadvantages.
    • Maintenance will be very difficult
    • Might cause collision.
  • 8.
    • What we did???
    • Rack-Pinion assembly gives good mounting convenience
    • Maximum gear losses– 3 to 5%
    • Efficiency– 95%
  • 9.
    • Construction of generator:
    • Initial experiments- DC motor as Generator
    • How is electricity generated???
    • Basic principle of generation of electricity.
    • What we did???
  • 10.
    • Challenges we faced!!
    • Selecting suitable generator.
    • Selection of springs.
    • Achieving proper balance of speed and torque.
  • 11.
    • 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.
  • 12.
    • 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.
  • 13.
