POWER GENERATION FROM SPEED BREAKERS

NEED FOR IT? In the present scenario power becomes major need for human life. Due to day-to-day increase in population and lessen of the conventional sources, it becomes necessary that we must depend on non-conventional sources for power generation.

To generate electricity using vehicle speed and weight as input.

Speed breaker POWER GENERATOR Converter is a non-conventional energy generation. It is electromechanical energy generating machine

MECHANISMSRack-Pinion

mechanismSpring coil

mechanism Crank shaft mechanismRoller mechanism

Here we are making the speed breaker of vibrating type, when a vehicle crosses the speed breaker, it gets pressed and then get backs to its original position.

The shape of the speed breaker is trapezoidal.

Construction Of Speed Breaker

The bottom layer of the trench is filled with concrete or with wooden plates.

CONSTRUCTION OF TRENCH

Deflection of spring=(64*w*n*N*r^3)/(G*D^4) Where W=designed load; r=mean radius of coil; D=diameter of wire; N=number of springs; n=no. of spring turns; G=modulus of rigidity;

Design of spring

When the load is on the speed breaker the volume of air compressed by it is found by, volume of compressed air= (volume of air in base –volume of spring)

CONTINUED….Maximum load on the speed breaker

is when the vehicle is on the middle of the speed breaker.

When the pressure in the FRL unit exceeds the defined value the valve opens and the pressurized air is given to the nozzle.

TRENCH

SPEED BREAKER

FRL UNIT

NOZZLE

Here the pressure energy is converted into kinetic energy i.e. pressure->high velocity.

This high velocity compressed air when hits the impeller makes it to rotate.

Nozzle

Casing, Runner and buckets.

This is provided to safe guard device against accidents.

CASING:

CONSISTS:

IMPELLER

It consists of a circular disc on periphery of which have number of buckets are evenly spaced are fixed. Each bucket is divided into two symmetrical parts by dividing valve known as splitter.

When the air strikes the runner, it rotates and continues rotation due to inertia.

RUNNER

ALTERNATOR It’s a device which converts

mechanical energy into electrical energy.

RACK-PINION MECHANISM

Various machine elements used in it: Rack-pinion SPROCKET GEARS FLY WHEEL SHAFT ELECTRIC GENERATOR

CONSTRUCTIONAL DETAILS

Transfer rotary motion between two shafts

SPROCKET MECHANISM

The input gear transfers power to output gear

GEAR MECHANISM

This is used to regulate the energy and maintain energy at an uniform level so that the shaft rotates at an uniform r.p.m .

FLYWHEEL

WORKING

BLOCK DIAGRAM

Low budget electricity production. Less floor area, No obstruction to traffic, Suitable at parking of multiplexes, malls, toll-

booths, signals, etc.

May not work with light weight vehicles. Regular maintainance is required.
