during transportation, the transport vehicle drives the container 1 to move (the container moves from left to right in the figure), outside air is blown into the water body of the container 1 from the air inlet box 21 through the air inlet pipe 22, the water body of the container 1 is aerated, oxygen in the air is fused into the water body to form dissolved oxygen for breathing of live fish in the water body, and the rest air flows into a cavity at the upper part of the container 1 and is finally discharged from the L-shaped air outlet pipe 4;
when the transport vehicle runs downwind, or runs at too low speed, or even stops running, namely when the wind speed measuring mechanism detects that the wind speed is lower than a certain limit, the turning plate 211 is driven by the stepping motor 20 to be opened to the maximum degree, so that the opening of the air inlet box 21 is opened to the maximum, the central controller controls the speed-adjustable motor to rotate, the aeration pump 5 is used for carrying out oxygenation on the water body in the container 1, and the rotating speed of the speed-adjustable motor is adjusted in real time along with the real-time wind speed detected by the wind speed measuring mechanism, so that the water body in the container 1 has enough aeration intensity;
when the transport vehicle runs against the wind or runs at an excessively high speed, namely the wind speed measuring mechanism detects that the wind speed is higher than a certain limit, the central controller controls the aeration pump 5 to stop working, and controls the stepping motor 20 to rotate according to the detected wind speed of the wind speed measuring mechanism, so that the turning plate 211 deflects for a certain angle, the opening degree of the air inlet box 21 is reduced, the air inlet section of the air inlet box 21 is reduced, and the water body in the container 1 is prevented from being excessively aerated; on the contrary, when the wind speed measuring mechanism detects that the wind speed is reduced, the opening degree of the air inlet box 21 is increased, so that the air inlet box 21 has a larger air inlet section, and the aeration rate is increased.
The device for improving the transport survival rate of the freshwater fish provided by the invention is described in detail above. The description of the specific embodiments is only intended to facilitate an understanding of the method of the invention and its core ideas. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
