Abstract
The utility model discloses a coaxial counter-current structure of oxygen consumption measuring apparatus for fish swimming relating to the experimental technique of swimming ability of fish and its determination of metabolism. Two side pipes of a swimming pipe (3) are respectively provided with honeycomb-shaped fluid director A (2) and a honeycomb-shaped fluid director B (5), an outer sleeve of the swimming pipe (3) is provided with an outer sleeve pipe (4), one end of the outer sleeve pipe (4) is provided with a magnetic pump (1) which can adjust the flow rate, inner threads of the other endof the outer sleeve pipe (4) are meshed with outer threads of a end cover (6), a sheet-shaped fixed bracket (7) is installed between the swimming pipe (3) and the outer sleeve pipe (4). The two sidepipes of the swimming pipe are respectively provided with the honeycomb-shaped fluid director, which can make the water flow pushed by the magnetic pump capable of adjusting the flow rate even and smooth, and the fish is caused to be in a normal swimming posture, the oxygen consumption at different swimming speeds can be accurately measured, meanwhile, the waterway with circular cross-section between the swimming pipe and the outer sleeve pipe makes the water-flow flow reversely. The overall accuracy of the measuring apparatus is high; the measuring apparatus is compact, and has small volume.
Description
One, technical field
