Automatic Fire Extinguisher

Abstract
The rapid depletion of existing fossil fuel sources and the environmental problems caused globally by the combustion products have made the whole world go crazy in search for alternative fuel to power the automobiles. The main aim is to reduce the usage of organic fuel powered vehicle and to design a vehicle which works perfectly in the growing fuel area i.e. electric powered vehicle. This will not only save the organic fuel but also to work upon the NO POLLUTION rides and future fuel. To begin it from the grass root a single passenger kart (named ERUDITE) powered by the 3 HP PMDC 48V motor is designed and fabricated, where the source of running the motor is 48V battery. To make our cause more meaningful alternative material (Aluminum 6063) is used for the frame rather than the conventional mild steel. The frame is designed in order to encapsulate all the components of the kart, including a driver, ergonomically and subjected it to various real life scenarios by performing finite element analysis using solid works simulation.Simple four bar mechanism is used to steer the kart to the required turning radius. Disc brake has been installed in rear wheels for the effective braking along with the handbrake as a precaution measure in case of brake failures. Sprocket and chain mechanism is used to transmit the power to the rear wheels.Statistically most of the accidents that occur in electric vehicles is caused due to fire. The major cause of fire in an electric kart is due to overload of motor especially during braking, short circuit in controller and battery. Since the hot spot of a motor is the armature, it is the first component to catch fire and hence the armature temperature has to be monitored continously so that fire can be prevented. According to neurologists, an average human brain takes 3 seconds to recognize the situation and another two seconds to react. This time is enough for a fire to spread and cause severe damage to the driver as well as the kart. Hence, an automated mechanism was designed and installed in the kart to extinguish any fire immediately.
