Power generation from speed breakers

  1. 1. Submitted by:Brati Sundar Nanda 1011016238 ECE-E
  2. 2. Introduction  Different mechanisms  Spring coil mechanism  Roller mechanism  Rack pinion mechanism  Different Comparisons  Merits and Demerit  Scope and Uses  Conclusion  References 
  3. 3.  A large amount of energy is wasted at the speed breakers through friction , every time a vehicle passes over it.  So electricity can be generated using the vehicle weight and speed (kinetic energy) as input.  So, this is a small step to try to improve this situation.
  5. 5.   o o Here we are making the speed breaker of vibrating type, when a vehicle crosses the speed breaker, it gets pressed and then it gets back to its original position. Dimensions of speed breaker:Height : 0.2m Width : 0.4m Length : 4m The material used in construction of speed breakers is steel. The shape of speed breaker is trapezoidal .
  6. 6. Height: 0.35m • Length : 4m • Width :0.45m • The bottom layer of the trench is filled with concrete or with wooden plates of 0.5m. •This is for cushion effect. •
  7. 7.  The actual height of spring is 0.3m before loading.  The deflection of the spring is given by  δ = 64 w *n*N*R^3 /(G^4) where  δ-deflection (in our case maximum δ =0.1m)  w=designed load  R= mean diameter of coil  n=no of spring turns  G= Modulus of rigidity = 8*10^4 N/m^2  N= No. of springs   The no of turns in the spring to get the deflection of 0.1m is given by  n= (0.1)G^4/(64 w*N*R^3)
  8. 8. Maximum load on the speed breaker is when the vehicle is on the middle of the speed breaker.  When the pressure in the FRL unit exceeds the defined level the valve opens and the pressurized air is given to the nozzle. 
  9. 9.  The diameter of the inlet of nozzle must be greater than outlet.  Here the pressure energy is converted to kinetic energy i.e pressure→high velocity.  This high velocity compressd air when hits the runner,makes it to rotate.
  10. 10.  It consists of a circular disc on the periphery of which have number of buckets evenly spaced are fixed. Each bucket is divided in to 2 symmetrical parts by a dividing wall is know as splitter.  When the air strikes the runner ,it rotates & continues rotation due to inertia.
  11. 11.  Here roller ,sprocket-chain arrangement is used.  Ratio of speed of roller to dynamo shaft is 1:4.
  12. 12. Sprocket mechanism  Transfers rotary motion between two shafts  Dynamo  It is the dc generator which is use to generate current  Generates current as per the Faraday’s Law 
  13. 13. • Speed Breaker Arrangement 1 • Roller Arrangement 2 • Sprocket Drives 3 • Chain Drive 4 • Dynamo shaft 5 • Battery 6
  14. 14.  The various machine elements used in the construction of power hump are  RACK-PINION  SPROCKETS  GEARS  FLY WHEEL  Dynamo
  15. 15.  Gear  mechanism The input gear transfers rotational motion to the output gear. RACK-PINION  It coverts linear motion to rotational and vice versa. 
  16. 16. Fly wheel  This is used to regulate the energy and maintain the energy at an uniform level so that the shaft rotate at an uniform r.p.m Constructional details
  17. 17.  Here the reciprocating motion of the speed-breaker is converted into rotary motion using the rack and pinion arrangement.  Rack and pinion gears normally change rotary motion into linear motion, but sometimes we use them to change linear motion into rotary motion.  The axis of the pinion is coupled with the sprocket arrangement.  The axis of the smaller sprocket is coupled to a gear arrangement.  Finally the gear arrangement is coupled with the generator

  19. 19. Vehicle load (Kg) Max. Vol. generated (volts) Mean Power (Watt) Charging Time (sec) 205 10.73 7.99 3.9 250 12.83 9.47 4 320 13.05 10.5 4.1 400 14.91 11.21 4.2
  20. 20. Merits Demerits Pollution free power generation. Selecting suitable generator. No obstruction to traffic. Selection of springs. Low Budget electricity production Achieving proper balance of speed and torque. Easy maintenance It gives low electric output
  21. 21. This mechanism is very economical and easy to install.  Two protocols of this type of speed breakers are developed in India .not practically implemented till date.  Practically implemented in New Jersey , China and Indonesia.  Lots of researches and investigations are going on to practically utilize this technique  By doing proper arrangements we may generate high power electricity 
  22. 22.  The existing source of energy such as coal, oil etc may not be adequate to meet the ever increasing energy demands. These conventional sources of energy are also depleting and may be exhausted.  These are some non-conventional methods of producing energy. This is a one step to path of exploring the possibilities of energy from several non-conventional energy sources.
