Introduction

This project aims for an advanced house. By taking the help of modern engineering and technology we are trying for building a floating house which will save us during flood. This process is very helpful in costal belt and flood areas. The building structure is mounted on several hydraulic cylinders. There is a provision to lift the entire infrastructure from the ground level to a specified height.

Component Description

Battery

We have used 12 volt lead acid battery here for back up.

Transformer

It consists of two coils of insulated copper wire linked by an iron core. Transformers are used to step up (increase) or step down (decrease) AC voltages. Energy is transferred between the coils by the magnetic field in the core. There is   no electrical connection between the coils. Here we have used a shell type step down transformer which step downs 230 volt AC to 12 volt AC. It can supply maximum 1 A current.

Hydraulics

Hydraulics allow machines to transmit force from one point to another using an incompressible fluid. In most cases, this also increases the force applied at one end for a given amount of effort.

Capacitor

A capacitor stores electric charge. Capacitors used here are mica and electrolytic type.

Resistor

A resistor restricts the flow of current. The resistors used here are carbon film and quarter watt type.

Transistor

A transistor amplifies current. It can be used with other components to make an amplifier or switching circuit. BC 547 is a general purpose transistor. It is an npn epitaxial silicon transistor. Its maximum collector current (DC) is 100mA.

LED (Light Emitting Diode)

It is a transducer which converts electrical energy into light energy.

Motor

A motor is a device which converts electrical power into mechanical power. Here we have used a 12 volt permanent magnet type DC motor. It is a gear type motor with high torque and low rpm.

Diode 1N4007

These are general purpose diodes. These diodes have high current capability and low forward voltage drop. The average rectified output current is one ampere.

NE 555

The 8-pin NE 555 timer is the most useful ICs ever made in the world. Its popular name is timer IC. It is used in many electronics projects. Just adding a few external components, it can be used to construct so many circuits. The 555 has three operating modes: Monostable mode, Astable mode and Bistable mode. It can withstand maximum supply voltage up to 16 volt. It has a maximum power dissipation up to 600mW.

7805 voltage regulator

The 7805 voltage regulator IC gives us a constant 5 volt DC power supply from a 12 volt rectified output voltage. So , where the rest of the 7 volt goes ? Actually, the rest 7 volt goes nowhere. It is dissipated as heat in the heat sink provided to the voltage regulator IC.

Relay

Generally relay is defined as an electromagnetic switch. The relay used here is a 12 volt ice cube type.

Working

When water level increases due to flood, the sensor circuit is activated which further operates the hydraulic cylinders to uplift the house from ground level. This process is repeated according to the height of increased water level. After a safe and certain level of house this process comes to a stable position. Hydraulic cylinder is a hydraulic actuator which creates linear movement by converting the hydraulic energy back to a mechanical movement.

Advantage

This process is very helpful in costal belt and flood areas.

This saves both lives and goods during flood.
