Garbage Arresting System
Summary
Trash and floating biota on water causes complications in the flow of water. However, this can be solved by this design of floating trash barrier which will arrest the floating matter and allow only water to flow past.
This is an improvement over earlier Floating Garbage Barrier Application Number 6054/CHE/2014
This barrier is make in sections, joined together section end to section end and deployed where necessary. The ends of the entire barrier is secured to land or anchored in ground.
The main barrier is a mesh and so arrests objects larger than its mesh opening size and allows water and smaller particles to pass through. The arrested matter can now be lifted off the water by equipment on riverbank or shores of the waterbody.

Description and working
In this floating barrier, wire mesh is held in vertical alignment by a system of floats and ballast.
The wire mesh (1) has buoyancy floats (2) perpendicular and horizontal at specific intervals. The buoyancy floats are connected to vertical member (3) which is in turn connected to the mesh with a washer plate (9). Thus the vertical member (3) helps to keep the mesh vertical by taking support of the buoyancy floats (2).
The chain (8) runs along the barrier and is connected to the upstream end of the vertical member (3). This adds to the tensile strength of the entire barrier. This also ensures the entire barrier floats properly when the surface velocity of the water increases. The drag force on the mesh is balanced by the upstream side chain and these two acting horizontally in opposite directions ensure the barrier is stable.
Ballast (4) is placed at bottom of the vertical member to provide a righting lever between the buoyancy float and the ballast, whenever the barrier is tilted.

The cosmetic top plate is an inverted TJ' shaped plate that is seated over the upper edge of the mesh and bolted in place. The function of this top plate (6) is to provide cosmetic improvement and also to protect the hands whenever the mesh is handled manually.
Horizontal stiffeners (7) are placed between the vertical members (3) to keep the mesh in shape and not let it get into a 'ripple' like "wavy' shape. This horizontal stiffener (7) is secured in place by using a washer plate (9) on opposite side of the mesh. This washer plate is also used to hold vertical member (3) in place.
The vertical member (3) has an inclined pipe (10) between the vertical and horizontal pipes to give strength at welding points.
When floating in water, the buoyancy floats ensure the system has more displacement of water than the system weight itself. It floats at a level where float is partly above water and partly below. When water flow brings trash and biota on surface, the water and smaller floating solid waste crosses the water whereas the larger floating matter which is bigger than the mesh opening size is stopped upstream of the mesh.
The combination of float and ballast ensure there is a positive metacentric height and the mesh floats vertically.
Adjacent sections of the barrier are connected together by bolting the adjacent end connectors (5) which are in turn welded to the mesh.
The bracket (11) is welded to forward end of the frame in order to secure the chain (8). The bracket has hold on upper and lower piece for passing a bolt. A vertical bolt runs through the bracket and the chain in and nut is secured to keep the bolt in place.
Improvement over the Floating Garbage Barrier -
The drag forces on the barrier is reduced by placing the floats perpendicular to the mesh and parallel to the water flow.
The tensile chain is placed upstream of the mesh and thus the downstream drag forces is balanced well by the tensile force in upstream direction on the chain. This horizontal spacing between the point of action of these two forces provide a correcting force whenever the barrier is tilted.
Claim 1
We claim this specific and whole arrangement of floats, mesh and weights to separate the solid waste from flowing waters.
