Development of propulsion system for water trash collector / Raudah Nordin

Every year the number of rubbish is increasing because of people who are irresponsible to our nature. Furthermore, river is highly exposed to pollutions where the number of rubbish is highest than the other place. To prevent this problem, many people have prepared the prototype of water trash collector to collect the rubbish along the river, lake and ocean. However, propulsion system is one of the main important parts to move the water trash collector. The result of the propulsion system of the water wheel will move along the river without any problem because the shape and the size of the water wheel is made in accurate measurement. However, the material of the product is important to choose because it will affect to the water wheel during rotating the blade. Material from PVC is use to fabricate the water wheel to withstand the pressure of water. The number of blade is six because it can move smoothly and did not move too fast during collecting the rubbish. The DC motor suitable for the water wheel because it has torque and will develop high speed to rotate the water wheel. This project is developed to the society to decrease the number of rubbish at river and increase the quality of water to drink. Human is less likely to expose to dangerous health issues due to contaminated river, if the water river is clean. In addition, the bad smell of surrounding will decrease and river can be main attraction place to visit by people. The prototype is made with patience to achieve the highest accuracy, so it can function really well
