Fish Escalator – Self-financing – Objective – Video descriptive – Photographs

Fish Escalator

Device for raising and lowering fish for the clearing of obstacles in rivers, generating electric energy

Self-financing

Device that generates electrical energy during the descent of the fish, compensating the energy consumed by the pumping necessary for the lift

Objective

Facilitate the movement of fish in the rivers, allowing them to rise and descend, avoiding the walls of the dams and other obstacles in the channels

THE ORIGIN


ORIGIN OF THE IDEA


Taking as reference the studies carried out in the province of Cabinda of the Republic of Angola.
Taking as reference the studies carried out in the province of Cabinda of the Republic of Angola.
For the generation of electric power, the assembly of small hydroelectric power plants was planned in the Luali river of the municipality of Buco Zau.
For the generation of electric power, the assembly of small hydroelectric power plants was planned in the Luali river of the municipality of Buco Zau
The forecast of the blockade of the river with dams of 6 to 8 meters high, led to the analysis of the consequences of the blockade, preventing the passage of fish and causing the annihilation of the fish fauna by the descent through the turbines.

The dams would prevent their use as food for the indigenous population. In the markets of Angola you can contemplate the use of fish in their natural or preserved form.

FUNCTIONING


As can be seen in the attached drawing, when the screw rotates on its axis in a counter-clockwise direction, or a clockwise direction, coupled to an electricity generator, it functions as a turbine for generating electrical energy with a performance similar to that of of the Kaplan turbines. With the descent of the water there is the descent of the fish in a simple and friendly way with them (“Fish friendly”). According to the experiences of turbine manufacturers of this type, damage to fish is practically non-existent. The fish is transported without any effort, in a space sized appropriately for safe and comfortable movement. At the same time electric power will be generated.
When in the channel, in the lower part of the system, fish with needs or intentions of lift or rise are detected, the operator, in person or remotely, will act on the generator to change its operation to that of an engine, performing the stoppage of the screw and the change of direction of rotation of the same in the sense of clockwise or clockwise direction. In this way the upward movement of the water and the fish that are resident in it occur. This pumping of water with fish is for them a transport similar to the one that the escalators suppose for the humans. In the prototype of design that is attached, you can observe the behavior of the ascent and descent of the fish considering two screws, one of ascent or lift and another of descent or descent. Electricity will be generated in the descent screw, and electric power will be consumed in the lift or rise screw.
Determining the needs of fish lift, at certain times of the day intermittently, the system can be considered as a generator of electricity in 90% of the time. In this way the system is perfectly fundable due to its large income derived from the processing of truly protective flows of the ecology because they serve the survival of river fauna.
