[0059] In an optional embodiment, the adjacent annular rings 21 are connected by a connecting piece 23, so that when the first motor 4 drives the filter cylinder 2 to rotate, all the annular rings 21 can rotate synchronously; the connecting piece 23 is made of insulating material, so that when the resistance is detected, the adjacent annular rings 21 cannot pass through the current through the connecting piece 23; one end surface of the filter cylinder 2 is open, and the opening is in contact with the inner wall of the warehouse body 1 in which the water inlet 14 is arranged, so as to surround the water inlet 14, so as to ensure that the water for fish culture entering the first area is in the filter cylinder, and the filtering of the water for fish culture is ensured; a first motor 4 is arranged on the outer wall of the warehouse body 1, the first motor 4 is connected with the end surface of the filter cylinder 2 which is sealed, and the first motor 4 is suitable for driving the filter cylinder 2 to rotate; the filtering effect is increased by the rotating mode of the filter cylinder 2, so as to avoid the increase of the fish feces to be filtered from causing the filter cylinder 2 to be unable to filter.

[0060] In an alternative embodiment, the first cover plate 16 and the second cover plate 17 are rotatably arranged on the top surface of the bin body 1; the first cover plate 16 corresponds to the first area 12, and the first cover plate 16 is adapted to open or close the first area 12; the second cover plate 17 corresponds to the second area 13, and the second cover plate 17 is adapted to open or close the second area 13; the bin body 1 can be opened through the first cover plate 16 and the second cover plate 17 to process the filtered fish excrement and the like, or to replace the filter cotton in the second area 13; the filter cotton and the like can be placed in the second area 13 to perform more fine filtering; the filtered water can be discharged through the water outlet 15 for recycling.

[0061] At least one other disclosed embodiment further provides a circulation control system using the above-mentioned intelligent fishery water circulation device, comprising: a control module, and a detection module electrically connected with the control module; the detection module is connected with the plurality of electrodes 22 arranged on the annular rings 21 in the filter cartridge 2, and the detection module is adapted to detect the resistance between adjacent annular rings 21; the control module is configured to adjust the water inflow of the bin body 1 according to the resistance; the detection module can be a voltage detection module, which detects the change of the voltage on the annular rings 21 by providing a constant current to know the change of the resistance; the filtered fish excrement will accumulate between adjacent annular rings 21; the detection module can be in communication with the electrodes 22 respectively.

[0062] When the fish excrement accumulates between the annular rings 21, the fish excrement as a conductor can allow the current to pass through, and the connecting piece 23 is made of insulating material and cannot allow the current to pass through, so that the accumulated fish excrement is equivalent to a resistance, and the length and height of the fish excrement accumulation are determined by detecting the resistance values at different positions.

[0063] In an alternative embodiment, the detection module is adapted to detect the resistance between adjacent annular rings 21, that is, after the filtering is completed, the water in the first area 12 is discharged to make the filter cartridge 2 completely above the water surface, at this time the control module is configured to first connect the detection module with the uppermost electrode 22 on the annular ring 21 closest to the water inlet 14, and then sequentially connect the uppermost electrodes 22 on the other annular rings 21 with the detection module from near to far, when the resistance cannot be detected for the first time, it is judged that there is no impurity at the corresponding annular ring 21 to determine the length of the impurity accumulation; and the control module is configured to connect the uppermost electrode 22 of one of the two adjacent annular rings 21 with the detection module, and the lowermost electrode 22 of the other annular ring 21 with the detection module, to obtain the resistance value detected at this time, and then sequentially connect the remaining electrodes 22 in the other annular ring 21 with the detection module from bottom to top, with the lowermost electrode 22 of the other annular ring 21 remaining connected with the detection module, to obtain the resistance value each time, and to obtain the height of the impurity between the adjacent annular rings 21 according to the change of the resistance value.

[0064] like Figures 4 to 7 As shown, for example, three electrodes 22 are equidistantly arranged on the ring 21. After one filtration cycle, the pumping of water into the chamber 1 is stopped, the rotation of the filter cartridge 2 is stopped, and the liquid in the first area 12 is discharged, at least ensuring that the filter cartridge 2 is completely exposed above the water surface. At this time, the rings 21 can be numbered sequentially, with the one closest to the inlet 14 being numbered 1. The total number of rings 21 is, for example, 20. In this case, the electrodes 22 in the same ring 21 are numbered sequentially from bottom to top, with the bottom one being number 1 and the top one being number 3. Electrode 22 is located at about half the height of the ring 21, electrode 1 is close to the bottom of the ring 22, and electrode 3 is close to the top of the ring. First, the control module controls the 3 electrodes in ring 21. Electrode 22 is connected to the detection module, and electrode 22 in ring 21 is also connected to the detection module. The resistance is measured at this time. If resistance is detected, it is determined that fish feces have accumulated between ring 1 and ring 22. Then, electrode 22 in ring 2 is disconnected from the detection module, and electrode 22 in ring 3 is connected to the detection module. Electrode 22 in ring 1 is kept connected to the detection module, and the resistance is measured again. If resistance is detected, it is determined that fish feces have accumulated between ring 1 and ring 22. This process is repeated until resistance can no longer be detected. For example, electrode 22 in ring 10 can be connected to the detection module. If the resistance value cannot be detected, it is determined that the fish feces have accumulated between rings 10 (21) and 9 (21). After detecting the length of the accumulated fish feces, the height of the accumulated fish feces between adjacent rings (21) is then detected, for example, the height of the accumulated fish feces between rings 1 (21) and 2 (21). First, connect the bottom electrode 1 (22) of ring 1 (21) to the detection module, and connect the top electrode 3 (22) of ring 2 (22) to the detection module. The resistance value is then measured for the first time. Next, connect electrode 2 (22) of ring 1 (21) to the detection module, while keeping electrode 1 (22) of ring 1 (21) connected to the detection module. The resistance value is then measured for the second time. If the resistance decreases, it is determined that the fish feces have accumulated to the point of contact with electrode 22 in ring 1. Electrode 22 in ring 1 is then disconnected from the detection module, and electrode 3 in ring 1 is connected to the detection module. Electrode 1 in ring 1 is kept connected to the detection module. The resistance value obtained at this time is measured for the third time. If the resistance value of the third measurement decreases compared to the resistance value of the second measurement, it is determined that the fish feces have accumulated to the point of contact with electrode 22 in ring 1. If the resistance value of the third measurement remains unchanged compared to the resistance value of the second measurement, it is determined that the fish feces have accumulated to the point of contact between electrode 22 and electrode 3 in ring 1.

[0065] In an alternative embodiment, the control module is configured to control the water inflow of the filter body 1 according to the length of the impurity accumulation and the height of the impurities, that is, the more the water inflow of the filter body 1 is increased when the length of the impurity accumulation is shorter; the more the water inflow of the filter body 1 is increased when the impurities are higher closer to the water inlet 14; for example, when it is detected that the fish excrement is accumulated between the No. 9 ring 21 and the No. 10 ring 21, it is judged that the length of the fish excrement accumulated in the filter cartridge 2 is less than half of the length of the filter cartridge 2, at this time, the water inflow can be increased to avoid excessive accumulation of fish excrement in the filter cartridge 2 at the same position, thereby avoiding the influence on the filtering performance; when the length of the fish excrement accumulated in the filter cartridge 2 reaches two-thirds of the length of the filter cartridge 2, the water inflow is kept unchanged; when the height of all the fish excrement exceeds half of the height of the ring 21 and the length of the fish excrement accumulation does not reach two-thirds of the length of the filter cartridge 2, the water inflow is increased; if the length of the fish excrement has reached or exceeded two-thirds of the length of the filter cartridge 2 at this time, it is judged that the filtering capacity of the filter cartridge 2 is insufficient, at this time, the control module connected to the communication module can send an alarm signal to the terminal such as the mobile phone of the management personnel, reminding the management personnel to overhaul and replace the circulation control system or to check the aquaculture water area whether the fish population density is too high or the feeding amount is too large.

[0066] In an alternative embodiment, the electrode 22 is connected with an ozone generator, and the ozone generator is connected with the control module; during the rotation of the filter cartridge 2, the electrode 22 is always above the liquid surface in the filter body 1; the control module controls the ozone generator connected with the electrode 22 above the liquid surface to generate ozone above the liquid surface in the filter body 1; the ozone is generated above the liquid surface in the first area 12 in the filter body 1, and when the part of the ring 21 below the liquid surface rotates from below the liquid surface to above the liquid surface, water will be adhered, which will drip down, and the ozone above the liquid surface can be brought into the water during the dripping process, thereby increasing the amount of ozone entering the water, increasing the disinfection effect of the ozone, and increasing the oxygen content in the water, and the dripping liquid can bring oxygen into the water, thereby increasing the oxygen content in the water.

[0067] In an alternative embodiment, the control module is configured to judge the electrode 22 above the liquid surface in real time according to the speed of the rotation of the filter cartridge 2, and the control module controls the ozone generator connected with the electrode 22 above the liquid surface to generate ozone above the liquid surface in the filter body 1; since the water inflow of the water inlet 14 can be regulated and known, the water pumping capacity of the first water pump 3 is also known, and the liquid surface height in the first area 12 can be accurately obtained, the rotation speed of the filter cartridge 2 can be accurately controlled by the first motor 4, and the electrode 22 above the liquid surface in real time is also known; when ozone disinfection is needed, the control module controls the ozone generator corresponding to the electrode 22 exposed to the water surface to form ozone above the liquid surface.

[0068] At least one other disclosed embodiment also provides a control method using the above-mentioned circulation control system, comprising: a detection module detecting the resistance on the circular ring 21; a control module adjusting the water inflow of the bin body 1 according to the resistance.

[0069] In summary, the intelligent fishery water circulation device, comprising a bin body 1, a partition 11 is arranged in the bin body 1 to divide the bin body 1 into a first area 12 and a second area 13; a filter cartridge 2 is rotatably arranged in the first area 12, and the filter cartridge 2 is suitable for filtering impurities in the liquid entering the first area 12; wherein the filter cartridge 2 comprises: a plurality of circular rings 21; the circular rings 21 are arranged at equal intervals, and adjacent circular rings 21 are parallel, so as to realize filtering of fish feces after the fish breeding water is pumped out, avoiding the influence of too much fish feces on the fish breeding water, and avoiding the deterioration of the fish breeding water.
