Description

BACKGROUND

Waterborne pollutants, such as floating debris and trash, can collect in large bodies of water or along shorelines and beaches. The pollutants create environmental concerns, being a threat to wildlife and health. In addition, the pollutants can degrade the aesthetics of the environment, which can negatively affect the economy, such as decrease in tourism or property value.

Removing floating debris can be time consuming, tedious and costly. Floating debris collection systems have been proposed to ease the effort of collecting the debris. However, such systems have been ineffective. For example, conventional systems do not into take account of changing water levels. The changing water levels can create stress in conventional systems. Such stress can cause defects or breakage, rendering the systems ineffective.

From the foregoing discussion, it is desirable to improve collection of floating debris.

DETAILED DESCRIPTION

Embodiments generally relate to collecting floating debris. FIG. 1a shows a top view of an embodiment of a floating debris collection system 110. The system, for example, is installed in a waterway 101, such as a river or a canal. The system can also be installed in other types of waterways or bodies of water. The system can also be installed in a body of water or a portion thereof to collect floating debris. In one embodiment, the collection system comprises first and second subsystems 120a and 120b. FIG. 1b shows a frontal view of the first subsystem. The frontal view is, for example, from the perspective of the direction of flow. Providing a collection system with other number of subsystems, including 1, is also useful.

Referring to FIGS. 1a-b, a subsystem is coupled to first and second sides or banks 109a-b of the waterway. It is understood that the first and second sides or banks can also be part of a shore of a body of water. In other words, it is not necessary that the banks be distinct banks, but instead can be a contiguous bank. As shown, a subsystem includes a floating debris trap 140. Front and side views of the floating debris trap are shown in FIGS. 6a-b. The floating debris trap, for example, comprises a box frame. The box frame for example, is rectangular in shape. Other types of shapes are also useful. Wire meshing, for example, is attached to the frame. The wire meshing contains debris that flow into the trap from the front while allowing water to flow through trap. The trap includes floats attached to the frame. The float keeps the trap on the surface of the waterway to trap floating debris. The float, for example, comprises floating booms 152 and 153. Other types of floating debris traps can also be used.

In one embodiment, the first subsystem traps debris floating through a first portion of the waterway while the second subsystem traps debris floating through a second portion of the waterway. The trap of the first subsystem can be located from about 15-50% the width of the waterway from the first side and the trap is located from about 15-50% the width of the waterway from the second side. In another embodiment, the trap of the first subsystem can be located from about 20-35% the width of the waterway from the first side and the trap is located from about 20-35% the width of the waterway from the second side. Locating the traps at other distances from the sides is also useful.

Links are provided on the trap. The links facilitates coupling of the trap to other components of the system. In one embodiment, the links are located at the corners of the trap. Locating the links at other parts of the trap is also useful. Various types of coupling links can be used. In one embodiment, a link comprises a support plate with an opening. The support plate is mounted to the trap along a first plane. The first plane, in one embodiment, is parallel to the plane formed by surface of the water. Mounting the support plate along other planes, such as, vertical to the plane of the surface of the water is also useful.

First and second floating guides 162 and 163 are provided. The floating guides include first and second ends. The ends include links for coupling to other components of the system. The links, for example, can be the same or similar type of links provided for the trap. In one embodiment, the floating guide links comprise a support plate with an opening. Other types of links are also useful. The links of a floating guide can be aligned in the same plane. Aligning the links of a floating guide on different planes is also useful. For example, the link on the first and second ends can be aligned in perpendicular planes.

The first end of the first guide is coupled to the trap. In one embodiment, the first end of the first guide is coupled to the side of the trap which is located closest to a bank of the waterway. Preferably, the first end of the first guide is coupled to the front corner of the trap closest to a bank of the waterway. Coupling the first end to other parts of the trap is also useful. In one embodiment, the second end of the first guide is coupled to a floating/adjustable mount mounted on the bank. Side and top views of an embodiment of the floating/adjustable mount are shown in FIG. 2a-b. The floating/adjustable mount provides flexibility to position the floating debris collection system to desired level depending on the water level of the waterway. The second end of the first guide, in one embodiment, should be as close to the bank as possible to avoid floating debris from passing through it.
