[0078] Specifically, refer to Figure 4 After the vacuum pump 260 sucks the air in the fish collecting drum 200, the air pressure inside the fish collecting drum 200 is reduced, so the seawater and / or fish caught connected to the fish suction pipe 210 are sucked into the fish collecting drum 200 by the atmospheric pressure. After the fish caught in the fish collecting drum 200 is fully sucked, air is added to the fish collecting drum 200 through the air filling channel on the fish collecting drum 200. Specifically, the air filling channel can be connected to the atmosphere or to the air filling device. After air filling, the first air pressure of the fish collecting drum 200 is greater than or equal to the preset air pressure; at this time, the valve of the fish outlet pipe 220 is opened, and the fish caught is pushed to the fish outlet pipe 220 by gravity and the pressure of the first air pressure, and then reaches the collection device. The vacuum pump 260 is arranged on the bottom plate 270, and the fish collecting drum 200 is arranged on the bottom plate 270 through the first support rod 250 and the second support rod 251.

[0079] In some optional embodiments, a support mechanism 280 is provided in the fish collecting cylinder 200, and a filtering mechanism 290 is provided on the support mechanism 280, and the filtering mechanism 290 is located between the inlet side and the outlet side of the fish collecting cylinder 200, and the inlet side of the fish collecting cylinder 200 is communicated with the fish suction pipe 210, and the outlet side of the fish collecting cylinder 200 is communicated with the fish outlet pipe 220, and a first electromagnetic transceiver is provided in the fish outlet pipe 220, and the filtering mechanism 290 includes a first filter screen and a second filter screen, and the first filter screen is arranged above the second filter screen, and the second filter screen translates the first filter screen through a stepping motor, and the fish suction pipe 210 sucks the catch in the aquaculture cage into After the fish collecting drum 200, it also includes: emitting a first electromagnetic wave to the entrance side of the fish collecting drum 200 through the first electromagnetic transceiver, and generating a first electrical signal after receiving the reflected first reflected wave; generating a signal strength spectrum according to the first electrical signal, and the signal strength spectrum is used to indicate the intensity of the first reflected wave changing with time; calculating the fish suction density of the fish suction pipe 210 according to the signal strength spectrum, and the fish suction density is used to indicate the ratio of seawater and fish caught by the fish suction pipe 210; determining a first distance for the second filter to be translated relative to the first filter according to the fish suction density and a preset density; and controlling the second filter to move the first distance in a preset direction relative to the first filter.

[0080] Specifically, refer to Figure 4-5, the first electromagnetic transceiver is arranged at the entrance side of the fish collecting drum 200, and the specific setting position is not limited. The first electromagnetic transceiver transmits the first electromagnetic wave to the entrance side of the fish collecting drum 200. After the first electromagnetic wave passes through the fish catch and seawater flowing into the entrance side, it reflects the first reflected wave. The first electromagnetic transceiver then generates a first electrical signal, and the first electrical signal reflects the absorption rate of the first electromagnetic wave that changes with time. After receiving the first electrical signal, the controller or the host computer generates a signal strength spectrum, and the signal strength spectrum indicates the intensity of the first reflected wave that changes with time. The peak frequency of the reflected wave intensity can be calculated through the signal strength spectrum, and the peak value represents the first electromagnetic wave reflected back by the fish catch. Therefore, the fish suction density of the fish suction pipe 210 can be calculated through the peak frequency, and the fish suction density indicates the ratio of seawater and fish catch sucked by the fish suction pipe 210. The first distance of the second filter net relative to the first filter net is determined according to the fish suction density and the preset density, that is, the amount of seawater in the fish collecting tube 200 that needs to be filtered is determined, so as to control the filtering speed of the seawater after the second filter net is relative to the first filter net, so as to meet the corresponding seawater filtering amount. The filtered seawater is discharged into the sea through the discharge pipe 240. The fish suction pipe 210 is provided with a first valve 211, through which the fish suction pipe 210 can be connected to the breeding cage; the fish outlet pipe 220 is provided with a second valve 221, through which the fish outlet pipe 220 can be connected to the collection device; the suction pipe 230 between the vacuum pump 260 and the fish collecting tube 200 is provided with a third valve 231, through which the vacuum pump 260 can be connected to the fish collecting tube 200; the discharge pipe 240 at the bottom of the fish collecting tube 200 is provided with a fourth valve 241, through which the fish collecting tube 200 can discharge seawater.

[0081] In some optional embodiments, the first filter net includes a plurality of uniformly arranged first filter plates 291 and first filter holes, the gaps between the adjacent plurality of first filter plates 291 constitute the first filter holes, the area of ​​the first filter holes is equal to the area of ​​the first filter plate 291, the second filter net includes a plurality of uniformly arranged second filter plates 292 and second filter holes, the gaps between the adjacent plurality of second filter plates 292 constitute the second filter holes, the area of ​​the second filter holes is equal to the area of ​​the second filter plate 292, and the determining of the first distance of translation of the second filter net relative to the first filter net according to the fish suction density and the preset density comprises: determining a target overlap between the first filter plate 291 and the second filter plate 292 according to the fish suction density and the preset density; determining the first distance according to the target overlap; and controlling the second filter net to translate the first distance relative to the first filter net in a preset direction by the stepping motor so that the overlap between the first filter plate 291 and the second filter plate 292 is equal to the target overlap.

[0082] Specifically, refer to Figure 6-8 , the first filter plate 291 and the first filter hole are evenly spaced, and the second filter plate 292 and the second filter hole of the second filter net also have the same structure. By sliding the second filter net in a preset direction, the second filter plate 292 will move to the first filter hole. Similarly, the first filter plate 291 will also block the second filter hole synchronously. The more translations, the higher the overlap, and the smaller the gap between the two, the slower the rate at which seawater is filtered. Therefore, by determining the corresponding seawater filtration rate, the target overlap can be obtained, and then the first distance is determined. The bracket mechanism 280 includes a first bracket 281 and a second bracket 282 that are symmetrically arranged, and the second filter net and the first filter net are supported by the first bracket 281 and the second bracket 282.

In the technical solution of this embodiment, the breeding net cage is raised from the first position of the support rod 110 to the second position by the lifting device, so that the fish in the breeding net cage can be sucked by the vacuum fish suction pump, and at the same time, the raised structure at the bottom of the breeding net cage can gather the fish at the edge area of ​​the bottom of the breeding net cage, so that the vacuum fish suction pump can catch all the fish in the edge area.
