ELECTRIC POWER GENERATION USING FOOT STEP MECHANISM-MECHANICAL PROJECTS

       Electric Power Generation Using Foot Step Method

Synopsis:

        In this project We are generating electrical power as non_conventional method by simply walking or running on the foot step.  Non-conventional energy system is very essential at this time to our nation.  Non-Conventional energy using foot step needs no input power to generate the output of the electrical power.  This project using simple drive mechanism such as rock and pinion assemble and chain drive mechanism.

ELECTRIC POWER GENERATION USING FOOT STEP METHOD

        For this project the conversion of the force energy is converted into electrical energy.  The control mechanismcarries the rack and pinion, D.C geberator, battery and invertor control.  We have discussed the various applications and further extensions also.

Introduction:

        Man has needed the used enery at an increasing rate for his sustenance and welll being ever since he came on the earth a few millliion years ago.  Primitive man required energy primarily in the form of food.  He derived this by eating plants or animals, Which he hunted.  Subsequently he discovered fore and his energy needs increased as he started to make use of wood and other bio mass to supply the energy needs for cooking as well as for akeeping himself warm.  With the passage of time, man started to cultivate land for agriculture.  He added a new dimension to the use of energyby domesticating and training animals to work for him.

With further demand for energy, man began to use the wind for sailing ships and for driving windmills, and the force of fa1ling water to turn water for sailing ships and for driving windmills, and the force of falling water to turn water wheels. Till this time, it would not be wrong to say that the sun was supplying all the energy needs of man either directly or indirectly and that man was using only renewable sources of energy.

WORKING PRINCIPLE

The complete diagram of the foot step power generation is given below. Only one step is inclined in certain small angle which is used to generate the power. The pushing power is converted into electrical energy by proper driving arrangement. The rack & pinion, spring arrangement is fixed at the inclined step. The spring is used to return the inclined step in same position by releasing the load. The pinion shaft is connected to the supporter by end bearings as shown in fig. The larger .sprocket also coupled with the pinion shaft, so that it is running the same speed of pinion. The larger sprocket is coupled to the small cycle sprocket with the help of chain (cycle). This larger sprocket is used to transfer the rotation force to the smaller sprocket. The smaller sprocket is running same direction for the forward and reverse direction of rotational movement of the larger sprocket. This action locks like a cycle pedaling action.

The fly wheel and gear wheel is also coupled to the smaller sprocket shaft. The flywheel is used to increase the rpm of the smaller sprocket shaft. The gear wheel is coupled to the generator shaft with the help of another gear wheel. The generator is used here, is permanent magnet D.C Stepper Motor. The generated voltage is 12Volt D.C. This voltage is further amplified using IC MC34063 DC-DC convertor and is stored to the Lead-acid 12 Volt battery.

The battery is connected to the inverter. This inverter is used to convert the 12 Volt D.C to the 230 Volt A.C. This working principle is already explained the above chapter. This 230 Volt A.C voltage is used to activate the light, fan and etc. By increasing the capacity of battery and inverter circuit, the power rating is increased. This arrangement is fitted in shopping complex, college and wherever the large people walking on the foot steps simultaneously.

ADVANTAGES

Power generation is simply walking on the step

Power also generated by running or exercising on the step.

No need fuel input

This is a Non-conventional system

Battery is used to store the generated power

APPLICATIONS
