Description

Combined fish blocking barrier Technical Field The utility model belongs to the technical field of ecological protection engineering, and particularly relates to a fish blocking barrier. Background The water retaining dam plays a role in water conservancy regulation and control, and meanwhile, the ecological channel for upstream migration of fishes is obviously blocked, and the ecological channel forms a living threat to downstream fishes. As a main path for fish to descend, the complex mechanical structure and turbulent water flow in the runner of the water turbine easily cause the fish to suffer from physical impact, sudden pressure change and other damages, and even cause large-scale death. In order to reduce the negative influence of the water turbine on aquatic organisms, the arrangement of an effective fish blocking barrier at the inlet of the runner becomes an important technical measure for protecting the migratory fish. The existing fish blocking barrier is mostly based on the fish behavior driving principle, and interference is formed through external stimulation so as to guide the fish blocking barrier to actively avoid the fish blocking barrier. For example, the bubble curtain is used to generate mechanical disturbance, the sound wave generator emits a specific frequency signal, or a stroboscopic light source is arranged to form a visual deterrent device, so that fish is forced to change a swimming path. Such barriers may reduce the probability of fish approaching the turbine runner. However, existing behavior-driven barriers have significant limitations in practical applications. The behavior driving device is usually arranged at the bottom of the water, so that the behavior driving device is influenced by the environment, an effective interception surface cannot be formed in an upper water area, and the deterrent effect of the behavior driving device is unstable. In addition, the sensitivity difference of different fish species to stimulus such as sound, light and air bubbles is obvious, and the obstacle avoidance requirement of multiple fish species is difficult to be covered by a single driving mode.
