Aqua Dredger River Cleaning Machine

Abstract

This project focuses on design and fabrication of the river waste cleaning machine. The work has done looking at the current situation of our national rivers which are dump with core liters of sewage and loaded with pollutants, toxic materials, debris etc. The government of India has taken charge to clean rivers and invest huge capital in many river cleaning projects like "Namami Ganga", ''Narmada Bachao'' and many major and medium projects in various cities like Ahmadabad, Varanasi etc. By taking this into consideration, this machine has designed to clean river water surface. Nowadays almost all the manufacturing process is being atomized in order to deliver the products at a faster rate but also at higher cost. Automation plays an important role in when it comes to smart work. In this project we have fabricated the remote operated river cleaning machine. The main aim of the project is to reduce the man power and time consumed for cleaning the river. In this project we have automated the operation of river cleaning with help of a motor and chain drive arrangement. Also a special purpose harvesting cutter is commissioned on a previous constructed model by other group of engineers. These project also emphasizes of the economical approach for implementation in urban areas. 1 INTRODUCTION Rivers are important part of human lives. But unfortunately, only few are aware of its importance. The proof: tons of trash in our rivers and creeks, making it look and smell like a dumpsite. The garbage in rivers is more than just an eyesore because it can possibly contaminate our drinking water and threaten nature, our lives, and that of our loved ones. Even a piece of litter thrown on the street may contribute to the piling garbage in our rivers and creeks. Rivers remain an important source of drinking water for many towns and cities. The water is purified first before it reaches to our tap. However, if our rivers remain polluted, the water can't be purified to the extent that it won't be suitable for human consumption anymore. It is crucial to look after our river systems and protect them from pollution to we want them to keep on flowing to our taps. Rivers provide habitat to a wide range of animal and plant species. However, these species are already critically endangered due to the rapid deterioration of our rivers. These endemic species, can only be found in the Philippines, may be saved if we clean up our rivers. Clean, healthy rivers reduce human health risk and improved quality of life. Less trash increase recreational activities along rivers-clean and safe walk and run trails for the community. As recreational activities increases, tourists will be attracted. This affects both the economy and well-being of the community. We could draw inspiration from Iloilo City. How they successfully revived their main river and built a beautiful Esplanade, the first of its kind in our country, with their key guiding principles of "unity, strategic planning, and political will". It's all up to us to make it happen. As human and industrial waste and garbage add up to the river pollution, each of us can do small things to help clean up our river and that adds up to the pollution solution 2 LITERATURE REVIEW Design, Fabrication and Analysis of Composite Marine Propeller, Dr, P Ravinder Reddy, CBIT, Hyderabad From this paper, a composite marine propeller is designed and modeled from three composite materials. The model is evaluated for its open water characteristics and cavitation performance numerically using hydro-elastic model. To validate the results, composite propeller is fabricated using open mold technique and is tested in cavitation tunnel available at NSTL vizag. From the results it is concluded that, the hydro-elastic model used for analysis of composite propeller is in close agreement with experimental results. The stacking sequence which contributed to the optimum performance is selected from the choice of stacking sequences. The results of the same are presented in this paper. Design of continuous loading vertical chain conveyor, Aditya Kulkarni, Tanmay Kulkarni,PES Modern college of Engineering, Pune, Maharshtra, A conveyor system is a common piece of mechanical Handling equipment that moves materials from one location to another. The main purpose of this project is to safely lift the load at the rate of 6m/min. This paper consist of, selection, the design of basic mechanical elements. This system is able to overcome the drawbacks of inclined belt conveyor, achieves desired height and occupies less floor space as the material is transformed in vertically upward direction. This Chain Conveyor utilizes a continuous chain arrangement, carrying a series of the single pallet for lifting the load. The chain arrangement is driven by a motor, and the material suspended on the pallets is conveyed to the next floor.
