Floating Garbage Collector System (Fgcs)

Abstract: Often we find many of our rivers are polluted with waste from industries, sewage system, people throwing garbage in it etc. The rivers become so polluted that neither any living creature can survive in it nor anyone can drink it. It basically disturb the whole eco system we live in. The river base fills with slit and slowly the river depth decreases causing severe floods besides water scarcity and whole river echo system is destroyed. The system conceptualized here is to address how we can remove the floating garbage from the rivers or the densely populated river banks (Ghats) with less investment and operational cost. It has basically 2 steel pillars at both ends of the river banks with pulley to rotate the comb like structure across the river collecting floating waste in due course and emptying it in garbage collector pits. It has a floating plankton installed at both the ends of the banks to guide/alter the height of the steel cables by adjusting the height of the pulleys accordingly. The Comb like structure has also have auto adjusting hydraulic arms, which reduces the weight on the steel cables and also helps mitigating the catenary effect due to the great distance between the pillars. If the River is too wide, the cable can be re-strengthen with intermediate pillars in its path. The structure ideally should installed immediately next to the bridges on that river so that we don’t have to spent too much money making it strong enough to sustain the river wrath in all the weathers. Also, people generally through waste into rivers from the bridges, so it can be collected and removed immediately besides it also makes it easy to operate and maintain as both the pillars are quickly accessible through bridge. Further the river flow can be utilized to propel the movement and deployment of the filtering combs by revolving the cables at defined intervals or continuously. Also we can use solar power as alternate energy to bring down the operational cost. This design has unique structure to make it simple yet more effective for the rivers which are victim of such garbage pollution. The conceptual Comb structure is designed to be light weight and auto adjust its height as it has air tight hollow base to manage the exact height of the combs in the varying water level conditions. Beside that it also reduces the catenary effect of the cable by which it is attached. It has coupler to attach the comb easily to the cable structure making it easier to replace if it is damaged. It also has a de-coupler which upon serious impacts (greater then specified limits) can de-attach it from the main cable so the damage can be minimized. Also it has ability to rotate the direction of the combs by 180o, so it can seamlessly can turn its direction before moving on the opposite direction cable (from A-Side to B-Side, Refer to figure 1 below). It has an adjustable weight attached to its Comb tail, which acts as counter balancing force when it collects the garbage and has to keep it against the river flow. In absence of this the river might uplift the whole comb structure and take away the garbage collected in it. At the same time if the force of the river flow is too high the weight is so calculated that it will let it go in that case. This is again to minimize the damage to the structure.  Also the weight attached to the tail of the comb is so designed that it can freely rotate on the tail axle and has grooves on it. This enables it to easily latch to the conveyor belt which pulls the comb upside down on both the river banks to empty the garbage and also help it to rotate the arm which has to move in the opposite direction so it needs to adjust the direction of the comb face. The pulley on both the steel poles can move up and down freely besides moving freely on its axis. The floating plankton on both the banks guide the motors to adjust the height of the steel cables as per the river water level. The collecting area of the garbage has filters installed on its base so the water coming out with the garbage can filter below it   and goes back to the river. The solid garbage will then be pushed (due to inclined plane) to the pit for further processing. Future State 1. The design of the Comb structure may require further enhancement to be more effective in collection of floating garbage and at the same time sustain the fury of the river and other solid floating objects in it. 2. Garbage collection pit can be improvised for better disposal. 3. The design can be altered to collect the floating garbage from the river banks (Ghats) or the sea beaches. Conclusion/result:  Based on the design and analysis we can build a cost effective system to collect the floating garbage from the rivers.
