ELECTRICITY GENERATION FROM SPEED BREAKER

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
  its 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 mechanisms
• 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.
