Abstract
The invention relates to a test method for simulating ship lock fish passing. A pipeline system is reasonably arranged on a ship lock wall and flushes the downstream with water. The flow velocity and the flow regime of the ship lock downstream can be changed by adjusting the water-flushing velocity and the ejection angle of a pipeline, so that the velocity of the downstream can reach the favorite velocity of the target fishes and the fishes are attracted into the ship lock to go up to the upstream. The invention further relates to a test device for simulating ship lock fish passing. The test device for simulating ship lock fish passing comprises a water groove. A water tank, a water pump, a speed regulating valve, a water shunting pipe and multiple water flushing pipelines with nozzles with adjustable angles are connected with the water groove through a PVC pipe in series. An automatic water level control gate is installed in the water groove. A dam body and a ship lock are arranged in the water groove in the lengthwise direction and the water flushing pipelines with the nozzles with the adjustable angle are arranged in the ship lock of the water groove. According to the test method and the test device for simulating ship lock fish passing, the effect of fish passing of a fish channel is improved as the pipeline is used for flushing and a light source is used for inducing the fishes, defects of an existing fish passing technology can be overcome, facility arrangement is simple and construction cost is low.
