Generating 9vdc From Tap Water
electricity is essential for powering electrical equipment that are used in carrying out daily tasks like lighting of homes and recharging of mobile phones or laptops. Considering this, today we will produce atleast 9Vdc of electric power from tap water.
The tap water Powered electric generator, generates voltage by harnessing the kinetic energy of flowing water.. It is made up of a storage tank, a dynamo blade, and a dynamo. The system works by directing liquid from the storage tank downwards through the dynamo, It rotates and transforms the kinetic energy of the liquid into electrical energy. The voltage produced is then stepped-up by dc to dc booster circuit before it can be used to power up electrical devices.
Supplies
Components Quantities
Dynamo blade x 1
Dynamo x 2
Voltage Regulator LM2577 x 1
Inductor: 100uh/3amp x1
Capacitor: .1uf/63volt x3
diode: IN5822 x 1
Resistor: 2.2k x2
Assemble the Dynamo Blade and DC Motors
position Motor: Place the two DC motors on a flat surface. The shafts of the motors should face each other, with a small gap in between.
Attach Dynamo Blade: Apply a small amount of glue to the dynamo blade and carefully position it between the two DC motor shafts. Ensure the blade is centered and balanced.
Secure motors:Allow the glue to dry completely. Ensure the dynamo blade is securely attached and can spin freely without obstruction.
Electrical Connection (series connection):Connect the positive terminal of the first DC motor to the negative terminal of the second DC motor using an electrical wire.
Output wires: Connect the remaining free terminals of the two DC motors to output wires. These wires will carry the generated voltage.
Test connection: Use a multimeter to check the continuity and ensure the series connection is correct.
3D print a stand: using 3D modeling software, design a stand that can hold the two DC motors in place and suspend the dynamo blade in the air.The stand should have two mounts to secure the DC motors.
Assemble the stand and Dynamo system
i.Mount Motors: Place the two DC motors into the mounts on the 3D-printed stand. Ensure they are secure and aligned properly.
ii.Suspension: Adjust the suspension arm to ensure the dynamo blade is properly positioned and can rotate freely.
iii. Secure Wiring: Ensure the electrical connections are secure and not interfering with th
e blade's movement.
DC to DC Boost Converter Circuitry
The dc to dc boost converter circuitry can step voltage up from 3.5V to 40V DC. The output voltage be can adjust by a 100K variable resistor and the maximum output power is 60w. This system was designed in different stages and then assembled together as a single unit. The reason for breaking down the construction into stages is to achieve a neat connection, detect fault location and testing.
procedures for connection:
The Voltage Regulator LM2577 consists of five terminals , terminal 1 is connected in series to resistor 1 and capacitor 1 before being grounded; terminal 2 is connected in series to resistor 2 and capacitor 2, and then grounded. Terminal 3 is grounded; the inductor is connected to terminals 4 and 5, Capacitor 3 is connect to the inductor and the diode is connected to the inductor before grounding .circuit diagram below
Testing the Dynamo System
i. Hydroelectric Setup: Place the entire setup in a position where water flow can spin the dynamo blade. This can be under a tap or any small water stream.
ii. Measure Output: Connect the output wires to a multimeter or a small load (like an LED) to observe the generated voltage when water spins the blade.
iii. Adjustments:Make any necessary adjustments to the blade positioning or motor alignment to optimize performance.
Summary
By following these steps, you will achieve a simple dynamo system using two DC motors and a dynamo blade. The system harnesses the force from tap water to generate electrical output when the blade is spun by water flow, demonstrating basic hydroelectric principles. The 3D-printed stand ensures the components are securely mounted and properly aligned for efficient operation.
