POWER GENERATION USING SPEED BREAKER PPT

POWER GENERATION POWER GENERATION USING SPEED BREAKERUSING SPEED BREAKER

Introduction: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.

OBJECTIVES:OBJECTIVES:

“Shaping Imagination”“Electricity”-Need of the hour

Scope, Merits and UsesScope, Merits and UsesLow Budget electricity productionLess floor areaNo obstruction to trafficEasy maintenanceSuitable at parking of

multiplexes, malls, toll booths, signals, etc.

Charging batteries and using them to light up the streets

BASIC PRINCIPLEBASIC PRINCIPLE::energy conversion from  mechanical

to electrical.to generate electricity using the

vehicle kinetic energy as inputwe can develope electricity from sp

eed breakersthey are using 3 different

mechanisms:I. Crank-shaft mechanismII.Roller mechanismIII.Rack- Pinion mechanism

Why Rack- Pinion Why Rack- Pinion mechanism??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 has some different disadvantages.

Maintenance will be very difficultMight cause collision.

What we did???

Rack-Pinion assembly gives good mounting convenience .

Maximum gear losses– 3 to 5%Efficiency– 95%

GeneratorHow 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.

ADVANTAGES:ADVANTAGES:

Low budget electricity production 

Less floor areaNo obstruction to trafficEasy maintenanceSuitable at parking of

multiplexes, malls, toll booths, signals, etc.

Uses: Charging batteries and using them to light up the streets, etc

DISADVANTAGESDISADVANTAGES::Selecting suitable generator.Selection of springs.Achieving proper balance of

speed and torque. It gives low electric output

conclusionconclusionAs day by day power consumption increases but electrics is is occur. So the minor needs of electricity such as street lights and traffic signals can be generated from speed breakers. Instead of wasting kinetic energy of vehicles at speed breakers the minor needs can be met by converting kinetic energy to electrical energy.
