[0002] Fish fry are also called "fish flowers". There are artificially bred fish fry and natural fish fry from rivers. When the fish fry are cultivated to a certain size, they need to be transported to a designated area for stocking. During the transportation process, a transportation device is needed to transport the fish fry. However, the existing transportation device has poor stability inside the box and large water fluctuations during transportation, which causes the fish fry to swing back and forth with the water, which can easily cause the fish fry to be damaged or fly out of the box. At the same time, the excrement produced by the fish fry during transportation can easily pollute the water body, reduce the oxygen content in the water body, and cause the fish fry to die of hypoxia, thereby increasing the cost of transporting the fish fry. Therefore, it is urgent to develop a silver carp and bighead carp fry transportation device that can increase the oxygen content in the water body, prevent the water body from being polluted, ensure the stability of the water body, and improve the survival rate of the fish fry during transportation.

[0022] Working principle:

[0023] When the utility model transport device is used, the fry to be transported is placed in the inner box body 4 together with the water flow, and during the transportation process, the water in the inner box body 4 can be supplied with oxygen through the oxygen supply box 12, and the oxygen generated by the oxygen supply box 12 is transported to the inner box body 4 through the air guide tube 13, and the oxygen is transported into the water in the inner box body 4 through a plurality of oxygen supply tubes 14 fixedly connected to the air guide tube 13, so as to increase the dissolved oxygen content in the transport water and prevent the fish from being short of oxygen during the transportation process.

[0024] At the same time, during the transportation process, the excrement and other impurities produced by the fry fall and deposit on the lower end of the inner box body 4. The fry are separated from the excrement impurities by the lower partition plate 5 arranged on the inner box body 4 to prevent the fry from stirring the deposited excrement impurities. At the same time, a slag collecting groove 41 is arranged on the lower end surface of the inner box body 4, and the two side surfaces of the slag collecting groove 41 are arranged obliquely, so as to facilitate the centralized collection of the excrement impurities of the fry; the centralized collected excrement impurities flow into the filter 8 through the sewage pipe 7 for filtration, and the filtered water flow is transported to the outlet pipe 10 through the return pipe 9 and discharged into the water body of the inner box body 4 through the several outlets arranged at the lower end of the outlet pipe 10. The several outlets arranged at the lower end of the outlet pipe 10 form the water flow into a plurality of water columns, and the several water columns flow into the water body of the inner box body 4 after contacting with the air, thereby increasing the contact area between the return water and the air, and further improving the oxygen content of the water body in the inner box body 4.

[0025] At the same time, a plurality of wave-breaking baffles 6 are arranged in the inner box body 4 to divide the water body in the inner box body 4 into a plurality of interconnected areas, so as to reduce the situation that the fry swings back and forth due to inertia during transportation. A buffer layer 15 is fixedly arranged between the inner box body 4 and the outer box body 1. The buffer layer 15 is made of high-elastic rubber, which has the effect of buffering and shock absorption, and prevents severe vibration from being directly transmitted to the inner box body 4; solves the problems of poor stability inside the box body and large water fluctuations during transportation, and a plurality of wave-breaking plates 16 arranged on the movable cover plate 3 are evenly distributed at equal distances and located between the wave-breaking baffles 6; further improves the wave-proof effect, and prevents the formation of water waves to impact the fry and cause stress to the fry.

[0026] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field.
