Collector with adjustable input/discharge to control sediment removal
View Patent ↗A collector for removing sediment from a waterway. The collector has a housing ( 24 ) with an opening ( 38 ) and an internal cavity ( 44 ) for receiving particles. Means for adjusting the type of sediment is provided. An inlet ( 120 ) communicates with the cavity for altering the amount of suction and controlling the water intake and the type of material removed.
1. A method of regulating removal of sediment from an associated waterway comprising:
providing a collector dimensioned for receipt in an associated waterway and having an opening that communicates with a collector cavity into which water and particulate material is received; and
providing a separate flow into the collector cavity in a direction substantially opposite to a receipt direction of the water carrying particulate material from the associated waterway whereby the separate flow regulates a desired removal of particulate material from the associated waterway.
2. The method of claim 1 including altering the rate of the separate flow into the collector cavity.
3. The method of claim 2 wherein the rate of the separate flow is less than a rate of flow of the water and particulate material into the collector cavity.
4. The method of claim 2 wherein the rate of the separate flow is greater than a rate of flow of the water and particulate material into the collector cavity.
5. The method of claim 2 wherein the rate of the separate flow is approximately the same as the rate of flow of the water and particulate material into the collector cavity.
6. The method of claim 1 including at least partially embedding the collector into a bottom surface of the associated waterway.
7. The method of claim 1 further including providing a collector having a sloping leading end and a sloping trailing end.
8. The method of claim 7 wherein the opening is located between the leading and trailing ends of the collector.
9. The method of claim 1 wherein the separate flow providing step occurs during removal of collected particulate material from the cavity.
10. The method of claim 9 wherein the separate flow providing step includes incorporating a pump in the collector.
11. A collector for removing sediment or particulate materials from an associated waterway, the collector comprising:
a housing having an opening that communicates with an internal cavity for receiving sediment/particulate material from an associated waterway; and
an adjusting mechanism that selects the type of sediment collected from the associated waterway, wherein the adjusting mechanism includes a passage that directs water flow from the associated waterway into the cavity in a direction substantially opposite to a receipt direction of sediment/particulate material from the associated waterway into the cavity.
12. The collector of claim 11 further comprising a pump communicating with the cavity for selectively removing sediment/particulate material from the cavity.
13. The collector of claim 11 wherein the housing includes a substantially planar surface containing the opening so that the collector is adapted to be substantially level with a bottom surface of the associated waterway.
14. The collector of claim 11 wherein the housing includes a sloping leading end and a sloping trailing end disposed on generally opposite ends of the opening.
15. The collector of claim 11 further comprising a pump received in the housing for removing sediment/particulate material from the cavity.
16. The collector of claim 11 further comprising a screen over the opening for controlling size of material that passes from the associated waterway into the cavity.
