Drive-assisted vertical slot fishway structure and fish collection method

Abstract

The invention discloses a driving assistance type vertical-seam fishway structure and a fish gathering method thereof. The driving assistance type vertical-seam fishway structure comprises a bottom plate, a side wall, multiple long separating plates, multiple short separating plates and multiple driving assistance platforms, wherein a fishway is divided into multiple pool chambers by the long separating plates and the short separating plates, and fish passing vertical seams are reserved between the long separating plates and the short separating plates; each driving assistance platform is formed by a J-shaped plate, an arc-shaped separating plate, a water outlet seam, a water supplementation seam and a small-sized wave generation machine, and arresting nets are arranged at the outer sides of the arc-shaped separating plates. According to the driving assistance type vertical-seam fishway structure disclosed by the invention, the water flow in the pool chambers and the fish passing situation in the positions of the fish passing vertical seams can be monitored in real time by cameras which are arranged in the long separating plates, images can be synchronously transmitted to a computer automatic control system for being analyzed, a command for regulating and controlling the frequency of the small-sized wave generation machine can be sent from the computer automatic control system to the small-sized wave generation machine, the water flow which is suitable for fish migration and the water sound which is capable of attracting fish to swim upstream can be formed in the corresponding pool chamber, the fish passing efficiency of a traditional vertical-seam fishway can be obviously increased, the influence on the fish migration caused by hydro-power and hydraulic engineering can be reduced, and the driving assistance type vertical-seam fishway structure is beneficial for ecological protection for a river.

Description

Technical field [0001] The invention relates to a fishway structure, in particular to a driving-assisted vertical slit fishway structure, belonging to the technical field of migratory fish crossing dam protection. Background technique [0002] The protection of aquatic organisms is an important issue that needs to be considered in the construction of water conservancy and hydropower projects. In view of the impact of the construction of water conservancy and hydropower projects on the habitat conditions and hydrological conditions required for the survival of fish and other aquatic organisms, the state has issued a number of relevant regulations and laws. It is used to reduce the damage caused by the blocking of upstream and downstream aquatic animals due to dam construction. In order to protect natural fishery resources and ensure the continuity and diversity of aquatic ecosystems, the main restoration measures currently taken are to build fish passages in hydropower and water c...
