1. A salmon migration lift device for facilitating migration of fish past dams and other obstacles in waterways, the salmon migration lift device comprising:
a motorized drive-gear based, gear-reduction set and clutch arrangement bucket lift system including:
a first bullwheel terminal proximal a lock on a downstream side of a waterway obstacle;a loading station disposed directly adjacent and in fluid communication with a portion of the downstream side of the waterway, the loading station comprising:
a reinforced concrete entrance chute disposed proximal the first bullwheel terminal and in fluid communication with the portion of the downstream side of the waterway in fluid communication with the loading station, the entrance chute configured to convey the portion of water from the downstream side of the waterway therethrough, the entrance chute having an entry end directly in the waterway, the entrance chute comprising:
an automatic solar powered valve controlled first gate disposed within the entrance chute proximal the entry end;an automatic solar powered valve controlled second gate disposed within the entrance chute and spaced apart from the first gate;wherein the lock is disposed between the first gate and the second gate;an electronic fish counter disposed within the lock;an upper end of a circulation pipeline disposed between the fish counter and the second gate;a reinforced concrete loading station chute in direct fluid communication with the entrance chute and directly adjacent to the second gate, the loading station chute disposed at a lower grade than a grade of the entrance chute, the loading station chute having an upper side directly adjacent the second gate and a bottom end, the loading station chute comprising:
an initial end of a return pipeline disposed in the bottom end of the loading station chute;an inclined grate disposed having a top end disposed at the upper side directly adjacent the second gate, a lower end,and a central portion between the top end and the lower end;an exit end of the loading station chute opposite the second gate;a shelf wall disposed on the exit end in a position above the return pipeline and below the grade of the second gate;wherein the portion of the downstream side of the waterway in fluid communication with the loading station flows through the central portion of the inclined gate into the bottom end and into the initial end of the return pipeline;a second bullwheel terminal on an upstream side of the waterway obstacle, the second bullwheel terminal including a horizontal pinion pulley;a continuously moving lift cable loop in operational communication with the first and second bullwheel terminals, the lift cable loop rotationally disposed between the first and second bullwheel terminals, the lift cable loop having a lower segment and an upper segment;a sliding mount body of the horizontal pinion pulley, wherein the sliding mount body is mounted to a counterweight on the lift cable loop, wherein the mounting of the horizontal pinion pulley to the lift cable loop is configured to maintain tension on the lift cable loop;at least two spaced apart cable support members, each cable support member directly connected to both the lower segment and the upper segment in a position perpendicular thereto and between a respective one of the first bullwheel terminal and the second bullwheel terminal;a plurality of spaced apart gondola buckets continuously suspended along the lift cable loop, a portion of the gondola buckets on the lower segment being conveyed by the lift cable loop from the first bullwheel terminal to the second bullwheel terminal and a portion of the gondola buckets on the upper segment being conveyed from the second bullwheel terminal to the first bullwheel terminal, wherein the gondola buckets are configured to carry fish therein, wherein each gondola bucket comprises:
a front side, a rear side, a right side, a left side, a closed bottom side, an open top side, and a storage container defined by the front, rear, right, left, bottom and top sides;a frame having a leg disposed on each of a corner of the top side and a crossmember connecting a top end of each leg, the crossmember attached to a proximal end of a grip, wherein a distal end of the grip is attached onto the lift cable loop;an upwardly slidable door disposed in the front side proximal the bottom side;each gondola bucket being independently disposed atop the shelf wall at a pre-set time interval when the respective gondola bucket is moved atop the shelf wall by the lift cable loop;a solar powered valve disposed on the gondola bucket in operational communication with the door, wherein the valve opens the door and alternately closes the door when the gondola bucket is disposed atop the shelf wall;a level sensor disposed on the front side proximal the top side, wherein the level sensor is in operational communication with the valve disposed on the gondola bucket;wherein the lower end of the inclined grate is disposed directly above and directly adjacent the storage container of the respective gondola bucket when the respective gondola bucket is disposed atop the shelf wall;wherein upon a predetermined count of fish within the lock and upon disposition of one of the plurality of gondola buckets atop the shelf wall, the second gate moves from a closed condition to an open condition, wherein upon the moving of the second gate to the open position, all fish within the lock are released through the second gate, across the inclined grate, and into the storage container of the respective gondola bucket having the door in a closed condition;wherein immediately subsequent to the opening of the second gate and the disposition of the respective gondola bucket atop the shelf wall, the respective gondola bucket is moved toward the second bullwheel terminal;an unloading station disposed proximal the second bullwheel terminal between the second bullwheel terminal and the loading station, the unloading station comprising:
a reinforced concrete fish exit chute having first end and a second end;wherein upon alignment of the door of the respective gondola bucket with the fish exit chute first end, the door is configured to automatically open, wherein the fish contained within the respective gondola bucket are released from the gondola bucket upon the automatic opening of the door into the fish exit chute and therefrom into the upstream side of the waterway;an uppermost end of the circulation pipeline disposed directly adjacent the first end of the fish exit chute and a lowermost end of the circulation pipeline in direct fluid communication with the loading station chute;a sand trap disposed proximal the circulation pipeline;a sand trap flush pipeline extending from the sand trap to the downstream side of the waterway;wherein the solar powered valve disposed on the gondola bucket is configured to open the door at a pre-set time interval at the unloading station regardless of the number of fish disposed within the lock as determined by the fish counter; a gondola bucket water refill station disposed directly adjacent the upper segment of the lift cable loop proximal the second bullwheel terminal; a refill pipeline extending from the circulation pipeline to the gondola bucket refill station, wherein water released from the gondola bucket into the fish exit chute and the circulation pipeline flows into the refill pipeline and therefrom through a refill valve and into the gondola bucket refill station, wherein water from the gondola bucket refill station is configured to flow into the respective gondola bucket; wherein upon the detection of a full level of the gondola bucket by the level sensor on the gondola bucket, the level sensor activates the refill valve to close the refill pipeline into the respective gondola bucket, wherein the refill pipeline maintains an open condition until the level sensor detects a full level when the respective gondola bucket is in fluid communication with the refill pipeline at the gondola bucket water refill station; a gondola drain station disposed proximal the lift cable loop proximal the first bullwheel terminal; a return pipeline extending from the gondola drain station into the downstream side of the waterway; and a plurality of support towers having a top end coplanar with an uppermost end of the waterway obstacle in a position above the waterway, the support towers being configured to support the bucket lift system in a proper operational condition. |
