2. 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.

4.  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

Roller mechanism

7.  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.

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

9.  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;

11.  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)
Maximum load on the speed breaker is
when the vehicle is on the middle of the
speed breaker.

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

13.  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.

14.  Casing,
 Runner and buckets.
 This is provided to safe guard device against accidents.

15.  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.

16.  It’s a device which converts mechanical
energy into electrical energy.

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

19.  Transfer rotary motion
between two shafts

20.  The input gear transfers
power to output gear

21.  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 .

24.  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.
