- 1.ELECTRICITY GENERATION FROM SPEED BREAKER
2.
- Introduction:
- Is anyone happy with current situation of electricity in India???
- So, this is our small step to try to improve this situation by our project.
- First of all what does electricity mean to us???
- Electricity- secondary source of energy i.e. converted from other sources.
- We need it for every small thing, still notice its importance only during load shedding.
3.
- OBJECTIVES:
- Shaping Imagination
- Electricity-Need of the hour
4. Scope, Merits and Uses
- Low Budget electricity production
- Less floor area
- No obstruction to traffic
- Easy maintenance
- Suitable at parking of multiplexes, malls, toll booths, signals, etc.
- Uses: Charging batteries and using them to light up the streets, etc.
5.
- BASIC PRINCIPLE:
- Simple energy conversion from Mechanical to Electrical.
- To generate electricity using the vehicle weight (potential energy) as input
- Possible using 3 different mechanism s:
- Crank-shaft mechanism
- Roller mechanism
- Rack- Pinion mechanism
6.
- Why Rack- Pinion mechanism??
- Crank-shafts are required to be mounted on bearings which creates balancing problem leading to mechanical vibrations which in turn damage the bearings.
- Secondly as bearings are of sliding type, any occurrence of variable load( which is bit obvious in case of vehicles!!) leads to balancing problem.
7.
- Roller mechanism has some different disadvantages.
- Maintenance will be very difficult
- Might cause collision.
8.
- Whatwe did???
- Rack-Pinion assembly gives good mounting convenience
- Maximum gear losses 3 to 5%
- Efficiency 95%
9.
- Construction of generator:
- Initial experiments- DC motor as Generator
- How is electricity generated???
- Basic principle of generation of electricity.
- What we did???
10.
- Challenges we faced!!
- Selecting suitable generator.
- Selection of springs.
- Achieving proper balance of speed and torque.
11.
- What we achieved???
- We LEARNT a lot.
- Constructed our own generator by applying the basic principle.
- Although we got less electrical output, we have successfully explained our idea of generating electricity from speed breaker.
12.
- Future Scope:
- Such speed breakers can be designed for heavy vehicles, thus increasing input torque and ultimately output of generator.
- More suitable and compact mechanisms to enhance efficiency.
