Abstract
A reservoir dredging assembly includes a dredging tube and at least one dredging device adapted to be installed to at least one secondary reservoir. The at least one dredging device includes a linking tube, an extending tube, a water gate, and a control unit. The linking tube is connected to the dredging tube for water in a primary reservoir, together with sediments deposited therein, to flow through. The extending tube has a top cutlet adapted to be located lower than the maximum water level of the primary reservoir. The water gate is mounted in the linking tube at a position downstream of the extending tube. The control unit is convertible between a first state for closing the water gate and a second state for opening the water gate.
Claims6
A reservoir dredging assembly comprising:
- a dredging tube adapted to be laid on a bottom of a primary reservoir;
- and
- at least one dredging device adapted to be installed to at least one secondary reservoir which is located downstream of the primary reservoir and which has a maximum water level lower than a maximum water level of the primary reservoir, and including
- a linking tube that is connected to said dredging tube, so that water in the primary reservoir, together with sediments deposited therein, is permitted to flow into said linking tube via said dredging tube,
- an extending tube that extends upwardly from said linking tube, and that has a top outlet adapted to be located lower than the maximum water level of the primary reservoir, and
- a water gate that is mounted in said linking tube at a position downstream of said extending tube;
- wherein, when said water gate is closed, the water advanced from the primary reservoir into said linking tube is directed into said extending tube and flows out of said extending tube from said top outlet;
- wherein, when the water level of the at least one secondary reservoir is reduced to be substantially equal to a height of said top outlet of said extending tube, said water gate is operable to be opened, so that the water in said linking tube is permitted to flow through said water gate;
- wherein said extending tube extends upwardly and obliquely from said linking tube;
- wherein said at least one dredging device further includes at least one auxiliary tube extending downwardly from said extending tube, and an auxiliary gate electrically connected to said control unit and disposed at a distal end of said at least one auxiliary tube;
- wherein when said water gate is closed, said auxiliary gate is operable to close for settlement of sediments which is carried by water in said auxiliary tube;
- and
- wherein when said water gate is opened, said auxiliary gate is operable to open for allowing the water in said auxiliary tube to flow into the at least one secondary reservoir.
