[0034] Embodiment 1:

[0035] A portable hypoxia stress experimental device of the present embodiment includes a folding plate 1, wherein the folding plate 1 includes at least one aeration surface, an aeration mounting groove 2 is provided on the aeration surface, and a nano aeration tube 3 is embedded inside the aeration mounting groove 2; a plurality of groups of folding probe mounting frames 4 are evenly distributed along the circumferential direction on the aeration surface, and a sensor component is installed on the clamping end of the folding probe mounting frame 4; an air inlet 5 connected to the nano aeration tube 3 inside the aeration mounting groove 2 is provided at the edge of the folding plate 1.

[0036] The folding disk 1 is made of any one of metal, ceramic, and polymer materials, ensuring that the folding disk 1 has a certain strength and corrosion resistance. The folding disk 1 includes a plurality of folding units that are movably connected to each other, and the folding units can be folded with each other, thereby reducing the volume of the entire device. Figure 2 As shown, when the folding unit is in the folded state, the aeration surface can be shielded for protection.

[0037] like Figure 1 As shown, in the working state, after several folding units are unfolded, the aeration surface is completely exposed, and the nano aeration tube 3 is embedded in the aeration installation groove 2 on the aeration surface, and the air inlet end of the nano aeration tube 3 is connected to the air inlet 5, and the air inlet end of the air inlet 5 is respectively connected to the nitrogen source and the oxygen source through a two-way pipeline, and the solenoid valve on the two-way pipeline can be used to control the nitrogen source or the oxygen source to be connected to the air inlet 5 in real time.

[0038] At the same time, several groups of folding probe mounting frames 4 are arranged circumferentially on the aeration surface. The folding probe mounting frames 4 can be folded and stored along with the folding units in a non-working state. In a working state, the folding probe mounting frames 4 can be unfolded along with the folding units, thereby driving the sensor components installed thereon to extend and distribute in the water body, and multi-point distributed detection of parameters such as dissolved oxygen content and temperature of the water body is performed through the sensor components, thereby ensuring the accuracy of the detection results.

[0039] The method of using this device is as follows:

[0040] The folding disc 1 is unfolded so that the aeration surface is fully exposed, and then the folding disc 1 is sunk into the water body, and nitrogen is supplied to the air inlet 5 through the nitrogen source, and then the nitrogen is filled into the water body through the nano aeration tube 3, so that the dissolved oxygen content in the water body is reduced. During the period of filling nitrogen, the dissolved oxygen content of the water body is monitored in real time by the sensor component, and the dissolved oxygen content data is transmitted to the external controller. When the dissolved oxygen content of the water body is reduced to a predetermined value, it indicates that the water body has reached a hypoxic state. At this time, the controller turns off the nitrogen source and turns on the oxygen source, and then fills oxygen into the water body through the nano aeration tube 3. During the process of filling oxygen, the dissolved oxygen content of the water body is monitored in real time by the sensor component, and the oxygen filling flow rate is adjusted to maintain a dynamic balance between the dissolved oxygen content in the water body and the oxygen consumption required by the aquatic organisms in the water body.

Aeration mounting grooves 2 are provided on the aeration surfaces of the first aeration plate 11 and the second aeration plate 12. When the first aeration plate 11 and the second aeration plate 12 are rotated and unfolded, the aeration surfaces are exposed, and when the first aeration plate 11 and the second aeration plate 12 are folded, the aeration surfaces are blocked.
