Embodiment
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, it is a kind of to be used for the experimental rig of fish activity and metabolic rate measure under hypoxemia including mixed
Close groove, gutter and measure groove, be provided with the diaphragm seal with Non-return air valve at the top of mixing channel and gutter, mixing channel and
The top of gutter is provided with dissolved oxygen probe, and the bottom of mixing channel is provided with inert gas outlet, the bottom of mixing channel with
The bottom of gutter is connected by connecting water pipe；The bottom center of gutter is provided with the propeller with motor, and water pump will be steady
Determine the bottom that the water in groove is discharged into measure groove from the bottom of gutter；Measure trench bottom is provided with inclined Porous Base；Surveying
The bottom for determining groove is provided with dissolved oxygen meter；The top of measure groove is provided with cover plate, the pipeline with dissolved oxygen meter is connected with cover plate, will
Determine the water discharge in groove.
Specifically, as shown in figure 1, the present embodiment includes including mixing channel 6, gutter 9 and measure groove 16 3 from left to right
Individual experimental tank.Being filled with nitrogen to the bottom of mixing tank 6 makes dissolved oxygen in water be reduced near setting value.Have in gutter water pump 24 to
Drawn water in measure groove 16, therefore water level is higher than gutter 9 in mixing tank 6, the two bottom is connected by pipeline 21 so that mixing tank
Hypoxemia water in 6 can enter gutter 9 by law of connected vessels；Hypoxemia water is entered in gutter 9 by the agitation of propeller 23
One step is well mixed, and water is pumped into measure groove by bottom water pump 24（The space of the lower section of 15 bottom plate of behavior observation room 26）, then pass through
The Porous Base 26 of behavior observation room 15 is even into observation ward 15；Water is entered by the opening of lid 17 on behavior observation room afterwards
Pipeline 18, bottle 29 is measured by dissolved oxygen, mixing tank 6 is returned to by pipeline 28 and 7, realizes water circulation.Dissolved oxygen in mixing tank 6
Bidirectional modulation is carried out by being filled with nitrogen and air, further improves dissolved oxygen control accuracy；The reclaimed water of mixing tank 6 flows out from below,
Flowed into by pipeline from top so that water (flow) direction is in opposite direction with bubble, can be beneficial to improve contact of the nitrogen/oxygen with water；
Mixing tank 6 and gutter 9 are all covered with transparent membrane 10, block the water in tank to carry out gas exchanges, film with air reclaimed water
Middle part is installed by one Non-return air valve 11 so that gas can be excluded by check valve in tank, but outside air cannot be introduced into；Mixing tank
6 are connected with the bottom of gutter 9 by pipeline 21, pass through the effect of water pump in gutter 24 so that water level is always higher than in mixing tank 6
Gutter 9, the reclaimed water of mixing tank 6 can automatically flow into gutter by law of connected vessels；Propeller 23 is installed in the bottom of gutter 9, leads to
Crossing the selection of propeller 23 is well mixed the hypoxemia water in gutter 9；Measure groove 16 includes behavior observation room 15 and observation ward
