1. FOOTSTEP POWER GENERATION SYSTEM Prepared by- Amar ELECTRICAL AND ELECTRONICS ENGG. NOIDA INSTITUTE OF ENGINEERING AND TECHNOLOGY, GREATER NOIDA 2. CONTENTS INTRODUCTION COMPONENTS MATERIAL SELECTION WORKING ADVANTAGES APPLICATIONS CONCLUSION 3. INTRODUCTION In this system 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. Nonconventional energy using foot step is converting mechanical energy into the electrical energy. 4. COMPONENTS LEVER RACK AND PINION SHAFT BALL BEARING RATCHET GEAR FLYWHEEL DC GENERATOR BATTERY INVERTOR 5. COMPONENTS OF FOOT STEP POWER GENERATION 1. LEVER A lever is a machine consisting of a beam or rigid rod pivoted at a fixed hinge. It is the simplest machine which is basically used to reduce the human effort. 6. 2.RACK AND PINION Rack and pinion is used to convert linear motion to rotary motion. In foot step energy generator generally pinion consists of 12 teeth and pitch circle diameter is 1 inch. Rack is 45.2 cm long and consists of 50 teeth. 7. 3.SHAFT Shaft is a mechanical component for transmitting torque and rotation. In foot step energy generator pinion and ratchet gear are mounted on the same shaft. 8. 4.BALL BEARING The purpose of ball bearing is to reduce rotational friction and support radial and axial loads. The diameter of inner ring is 2.5cm. 9. 5.RATCHET GEAR A ratchet gear a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. 10. 6.FLYWHEEL A flywheel is a rotating mechanical device that is used to store rotational energy. In foot step energy generator flywheel is used to drive the DC generator which produces the electrical energy. 11. 7.DC GENERATOR It is an electrical device which is used to convert mechanical energy into electrical energy. 30 volt DC generator has been used in foot step energy generator. 12. MATERIAL SELECTION Mild steel is a type of steel that contains small amount of carbon and other elements. It is softer and more easily shaped than higher carbon steels. It also bends a long way instead of breaking because it is ductile. Mild steel is a carbon steel which contains 0.25% Carbon 0.4%-0.7% Manganese 0.1%-0.5% silicon 13. COMPLETE ASSEMBLY 14. WORKING The complete diagram of the foot step power generation is given below. 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 generator is used here, is permanent magnet D.C Stepper Motor. The generated voltage is 12 Volt D.C. This voltage is further amplified using DC-DC convertor and is stored to the Lead-acid 12 Volt battery. 15. 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 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. 16. ADVANTAGES Reliable, Economical, Eco-Friendly. No need of fuel input. This is a non-conventional system. Battery is used to store the generated power. 17. APPLICATIONS Power generation using foot step can be used in most of the places such as:- Colleges, Schools, Cinema theatres, Shopping complex Railway stations Airports Bus stand, etc. 18. CONCLUSION Foot step energy generator is suitable for small amount of power generation such as charging cell phones, door lightnining and hoarding street lamps. For efficient working it should be used where people walk frequently such as malls, foot paths, railway stations, etc. 19. THANK YOU
