Problems solved by technology

[0002] Schools of fish like to swim from downstream to upstream. Fish can breathe oxygen better and catch prey more easily when they are against the current. Some fish will swim to the upstream birthplace for production according to the memory of production. When the fish school swims from the downstream to the upstream, some fish in the fish school may not be able to reach the upstream due to the speed of the water flow, which leads to separation from the fish school, making it difficult for a single fish to prey, and also delays spawning period of some fish

Abstract

The invention relates to a device for entering the upstream of a river dike, in particular to a device for assisting a school of fish to enter the upstream of a river dike. Therefore, the device for assisting the school of fish to enter the upstream of the river dike can guide and assist the school of fish to quickly enter the upstream of the river dike. According to the technical scheme, the device for assisting the school of fish to enter the upstream of the river dike comprises a backflow box, a flow pipeline, a first water pipe, an adjusting box, a first guide rod, a first baffle, a watertank, a first spring, a second water pipe, a water stop plate, a first supporting plate and the like; a first through hole is formed in right side of the top of the backflow box, the flow pipeline isconnected to the left portion of the upper part of the backflow box, the first water pipe is connected to the upper portion of the right side of the flow pipeline, and the adjusting box is connected to the inner top of the backflow box. According to the device for assisting the school of fish to enter the upstream of the river dike, water flows into the backflow box through the flow pipeline, thewater flows from the first pipe into the water tank, so that the water tank moves downwards, the first through hole opened by the first baffle, and the water flows from the second pipe to the outsideof the backflow box to guide the school of fish to enter the backflow box.

Description

technical field [0001] The invention relates to a device for entering the upstream of a river dam, in particular to a device for assisting fish to enter the upstream of a river dam. Background technique [0002] Schools of fish like to swim from downstream to upstream. Fish can breathe oxygen better and catch prey more easily when they are against the current. Some fish will swim to the upstream birthplace for production according to the memory of production. When the fish school swims from the downstream to the upstream, some fish in the fish school may not be able to reach the upstream due to the speed of the water flow, which leads to separation from the fish school, making it difficult for a single fish to prey, and also delays The spawning period of some fish. Contents of the invention [0003] In order to overcome the problem that some fish cannot reach the upstream because the speed of the water flow is too fast, thus dispersing with the fish school, causing a sing...
