Introduction:- A large amount of energy is wasted at the speed breakers

through friction , every time a vehicle passes over it.

So electricity can be generated using the vehicle weight (potential energy) as input.

So, this is a small step to try to improve this situation.

BASIC PRINCIPLE:-

Simple energy conversion from Potential energy to Electrical energy.

To generate electricity using the vehicle weight (potential energy) as input

Possible using 3 different mechanisms:1. Crank-shaft mechanism2. Roller mechanism3. Rack- Pinion mechanism

The crankshaft is a mechanism that transforms linear moment into rotatry movement and vice versa.

Whenever the vechicle is going on the speed breaker the speed breaker goes downward. so, the potential energy is converted into kinetic enery of the crank shaft.

3.RACK AND PINION MECHANISM:-

The various equipments are : Rack-pinion

Sprockets

Gears

Flywheel

Dynamo

CONSTRUCTION

WORKING PROCEDURE:- Here the reciprocating motion of the speed-breaker is converted

into rotary motion using the rack and pinion arrangement.

Rack and pinion gears normally change rotary motion into linear motion, but sometimes we use them to change linear motion into rotary motion.

The axis of the pinion is coupled with the sprocket arrangement.

The axis of the smaller sprocket is coupled to a gear arrangement.

Finally the gear arrangement is coupled with the generator.

circuit diagram:-

Coupled the wire of dc generator with dc holder and then these wires are coupled with the battery terminals .

Coupled the battery positive and negative with inverter (DC to AC).

Inverter input coupled with ac bulb and voltmeter.

Power calculation:-• The mass of any vehicle travelling over the speed breaker=

300Kg (Approximately)

• Height of speed brake = 15 cm = 0.15 m

• Work done = weight of the body x distance travelled by the vehicle

• Here, Weight of the Body = 300 Kg x 9.81 = 2943 N

• Distance traveled by the body = Height of the speed breaker = 15cm

• Power = Work done/Second = (2943 x 0.15)/60 = 7.3575 Watts Output

Contd…• Power developed for 1 vehicle passing over the

speed breaker

• Arrangement for 1 minute = 7.3575 watts

• Power developed for 60 minutes (1 hr) = 441.45 watts

• Power developed for 24 hours = 10.5948 Kw

• This power generated by vehicles is more than sufficient to run four street lights in the night

VOLTAGE GENERATED (VS) SPEED OF VEHICLE:-

VOLTAGE GENERATED (VS) LOAD:-

ADVANTAGES:-

Power generation with low cost and using non-conventional energy sources which will help us to conserve the conventional energy sources to meet the future demand.

Pollution free. compact mechanisms Less floor area No obstruction to traffic. The project is eco-friendly.

DISADVANTAGES:-

We have to check mechanism from time to time

It can get rusted in rainy season

May not work with light weight vehicles

Less quantity

CONCLUSION:-

Power generation does not require any fuel input and the running cost is very less.

There are some non- conventional methods of producing energy. This project is a step to path of exploring the possibilities of energy from several non- conventional energy sources.

FUTURE SCOPE:-

Suitable for parking at multiplexes, malls, toll booths, signals, etc.

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

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.
