WORKING
PRINCIPLE: While moving, the vehicles
possess some kinetic energy and it is being wasted.
This kinetic
energy can be utilized to produce power by using a special
arrangement called POWER HUMP. It is an Electro-Mechanical unit. It utilizes both mechanical
technologies and electrical techniques for the power generation and its storage. POWER HUMP is a dome
like device likely to be speed breaker. When ever the vehicle is allowed to pass over the
dome it gets pressed downwards then the springs are attached to the dome are compressed
and the rack which is attached to the bottom of the dome moves downward in reciprocating motion.
Since the rack has teeth connected to gears, there exists conversion of reciprocating
motion of rack into rotary motion of gears but
the two gears
rotate in opposite direction.
A flywheel is mounted on the shaft
whose function is to regulate the fluctuation in the energy and to make the energy uniform. So
that the shafts will rotate with certain R.P.M. these shafts are connected through a belt drive to
the dynamos, which converts the mechanical energy into electrical energy. The conversion will
be proportional to traffic density. Whenever an armature rotates between the magnetic
fields of south and north poles, an E.M.F (electro motive force) is induced in it. So, for inducing the
E.M.F.armature coil has to rotate, for rotating this armature it is connected to a long
shaft. By rotating same e.m.f, is induced, for this rotation kinetic energy of moving vehicles
is utilized.
The power is generated in both the directions; to convert this power into one way a special component is used
called zenor diode for continuous supply. All this mechanism can be housed under the dome, like
speed breaker, which is called HUMP. The electrical output can be improved by arranging
these POWER HUMPS in series. This generated power can be amplified and stored
by using different electrical devices.
The various
machine elements used in the construction of power hump are
x RACK
x SPUR
GEAR
x FLY WHEEL
x BEARINGS
x SHAFT
x SPRINGS
x ELECTRIC
DYNAMO
A dome is
mounted on four springs and in the bottom, a rack is clamped. The
rack consists
contact teeth on both the faces. It is connected to two gear wheels
to rotate the gear wheels only in one direction. We have inserted a free wheel in each gear. The
free wheel and the gear assembly are mounted centrally. The flywheel is also mounted on the
same shaft and the shaft is simply supported at the both ends by means of ball bearings. Now a
dynamo is connected to each shaft by belt drive. The output terminal of dynamo is connected to an
electrical storing device. The total assembly is arranged in concrete
pit.
