Fabrication Of Electrical Energy From Speed Breaker
In most of the countries, power remains one of the biggest problems. To alleviate the power shortage problem, different renewable energy sources are being investigated, including solar, wind, bio-mass and bio-gas. Here we would like to investigate another approach to extract power.
With few roads and plenty of vehicles on roads with heavy traffic is imminent and is among the other problems Bangladesh faces. Instead of viewing this as a problem, it could be turned into a blessing for the country. This project aims to harness the potential energy of the moving traffic and convert it into electrical energy that can be used.
Our primary aim is focused on the speed breakers that are placed on the roads. The mechanism works as such that; when a passing vehicle slows on a speed breaker the speed breaker would dip vertically downwards due to the weight placed on it. This vertically translational movement is then converted into rotational movement by means of a mechanical system which then can be used to drive a dynamo to generate electricity. The whole process of generating electricity will be remarkably simple, pollution free, and will come at a minimal cost. Different functional blocks of a speed breaker system to generate electricity is shown below.
POWER GENERATION USING SPEED BREAKERS:
Whenever 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 into reciprocating motion. Since the rack has teeth connected to gears, there exists, conversion of reciprocating motion of the rack into rotary motion of gears but the two gears rotate in opposite directions. A flywheel dismounted 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
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. Powerhump is a dome like device likely to be speed breaker
The primary function of the flywheel is to act as an energy accumulator. It reduces the fluctuations in speed. It absorbs the energy when demand is less and release the same when it is required.
It is a rotating element, which is used to transmit power from one place to another place. It supports the rotating elements like gears and flywheels. It must have high torsional rigidity and lateral rigidity.
It is defined as an elastic body whose function is to distort when loaded and to recover its original shape when the load is removed. It cushions, absorbs or controls energy either due to shocks or due to vibrations.
It is a machine element, which supports other machinery. It permits relative motion between the contacting surfaces, while carrying the loads. They reduce the friction and transmit the motion effectively.
It is a device, which converts mechanical energy into electrical energy. It works
Based on “Faraday’s laws of electromagnetic induction”.
