A novel shaftless pump-driven river algae experimental device

Abstract

This utility model discloses a novel shaftless pump-driven river algae experimental device, relating to the field of aquatic ecological simulation and early warning prediction technology. It includes an experimental water tank, a propulsion pump, and vortex-generating impellers. The experimental water tank has a ring-shaped structure, with a filling space at the bottom for filling with substrate and a water passage at the top. The propulsion pump is installed inside the experimental water tank to circulate the water within the passage. Multiple vortex-generating impellers are installed inside the experimental water tank to generate vortices in the water within the passage. This device can effectively simulate the hydrodynamics and aquatic environment of a real river in a closed loop, and is compatible with river ecological physics simulations based on water level differences. It offers advantages such as realistic simulation environment, minimal bubble turbulence, low background noise, and long-term algal survival friendliness, making it particularly suitable for experimental research on algae simulation, regulation, and early warning prediction.
