AI Technical Summary

Benefits of technology

This patented technology allows for better control on how fish travel within specific areas while reducing environmental impact associated with traditional methods such as reservoir construction and land use regulations. It includes various features like flexible boat platforms made from materials called Flexible Floating Labs®, rods attached to buoys, rotatable drums connected between them, and sensors placed near the dams. These technical means help prevent accidental injury when moving boats into different directions. Additionally, this system uses hydroelectric systems instead of fossil fuel sources to generate electrical current, making it safer than other alternatives even if they were temporarily installed outside buildings. Overall, this technology provides an efficient way to capture fish throughout varying environments and has potential applications beyond conservation purposes.

Problems solved by technology

This technical problem addressed in this patents relates to improving the efficiency of navigational systems on rivers with limited access areas caused by factors like sediment accumulation overboard during regulations related to energy production. Current designs require permanent structures made from concrete materials, making them rigid and inflexible at best. Additionally, current fish gates can only allow passage between different levels while keeping out competition conditions.

Embodiment Construction

[0089] The following specific embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0090] The present invention will be further described below in conjunction with the accompanying drawings, but it is not used to limit the protection scope of the present invention.

[0091] The present invention will be further described below in conjunction with the accompanying drawings.

[0092] As shown in Figure 1, the lifting device 1 can raise or land the fish net box 9 by its built-in electric device or manually, and the equipment 2 will move the fish net box 9 over the dam 13, and then place the fish from the fish net box 9. In the tank 4, the fish tank 4 is a device for releasing fish to the fish guide tank 5, and the fish slides along the chute to the head end 6 of the fish guide tank 5; the fish guide tank 5 is used to guide the fish to swim to the end of the reservoir The water tank, its head end 6 is closed wit...

Abstract

The invention relates to a method helping fish to go through the dam, which belongs to the fish protection technologies field. The method is: collect fish with fish collecting platforms downstream of the dam, then transport over dams, put in the guiding flume that dam leads to the end of the reservoir. The advantages of the present invention lies in that considering fish go through the dam, consider upstream transport at the same time, combines the fish guiding flume in design, by laying guiding flume on the shore or in water to transport fish to the tail of reservoir, combines traditional fish road features in guiding flume design, so that the fish can keep physical force in movement.
