Fish movement training experiment device

Abstract

The invention discloses a fish movement training experiment device, comprising a cylindrical experiment water tank. The device is characterized in that the experiment water tank is internally provided with a water treatment pipe which is also cylindrical and is coaxial with the experiment water tank. The top of the water treatment pipe is provided with a filtering unit. The filtering unit is internally provided with a plurality of filtering layers. A baffle is arranged under the filtering unit. The baffle is provided with a plurality of via holes. The side wall of the bottom of the water treatment pipe is provided with a plurality of water inlets. The water treatment pipe is internally provided with a circulating water pump. The water outlet pipe of the circulating water pump is communicated with a vertical pipe which is arranged on the inner wall of the experiment water tank. The vertical pipe is uniformly provided with a plurality of water injection nozzles on a longitudinal direction. The injection direction of the water injection nozzle is a tangential direction of a circle which is formed on the cross section of the experiment water tank. The top end of the vertical pipe is connected with a horizontal pipe above the experiment water tank. The horizontal pipe is also provided with a regulating valve. The water outlet end of the horizontal pipe is above the top end opening of the water treatment pipe.

Description

technical field [0001] The invention relates to an experimental device, in particular to an experimental device for fish movement training. Background technique [0002] Continuous exercise training at an appropriate water velocity can speed up the growth rate of fish, improve feed utilization, reduce the frequency of mutual attacks, enhance immunity, improve muscle quality, thereby reducing breeding costs and improving economic benefits. Therefore, carrying out research on fish sports training has important theoretical and practical significance for improving fish farming technology. Fish movement training experiments require an experimental device that can form a stable water flow with an adjustable flow rate. Due to the long period of the experiment (generally 1 to 2 months), it is also necessary to configure a circulating filter device to maintain normal water quality. Most of the traditional experimental devices are rectangular runway-type experimental water tanks, us...
