[0003] In the rainbow trout circulating water aquaculture system, mainly through equipment such as microfilters and screens, impurities with larger particles in the water body are removed, such as the feces of rainbow trout, uneaten feed residues, etc. The microfilter uses a filter screen to filter and can intercept most suspended solids, preventing these impurities from accumulating in the water body, avoiding clogging subsequent treatment equipment and affecting water quality. However, biological flocs will grow on the filter plate of the rainbow trout circulating water aquaculture system. Biological flocs are flocculent substances with a certain structure formed by the mutual adhesion and aggregation of various microorganisms, organic and inorganic particles, and extracellular polymers secreted by microorganisms. The excessive accumulation of these biological flocs will affect the normal operation of the filter plate, reduce the purification rate, and during the purification process, the sediment and feces deposited in the water body cannot be well cleaned deeply, affecting the aquaculture environment.

[0015] The beneficial effects of the present invention are as follows: 1. During the use of the device, the water body is purified by the filter plate. At the same time, the rotation shaft and the cleaning plate are used to clean the impurities attached to the surface of the filter plate, reducing the blockage of the filter plate and ensuring the filtering effect. As the purification and filtration continue for a long time, the liquid level of the pond water pumped into the purification tank will gradually rise. When the water level is higher than the height of the buoyancy ball, the buoyancy ball will be driven to rise by the buoyancy force, and the piston rod II will be stretched and moved upward. The piston rod II squeezes the air inside the inner cylinder and discharges it into the gap between the outer cylinder and the inner cylinder through the ventilation holes. When one end of the piston rod II is higher than the liquid discharge hole, the reagent is discharged into the purification tank through the gas pressure. The rotation of the cleaning plate not only realizes the release of the reagent but also evenly stirs it to accelerate the rapid decomposition of the biological flocs, improving the cleaning and purification efficiency.

[0016] 2. While the second motor drives the rotating shaft to rotate, it can drive the second magnet to rotate synchronously. Due to the interaction between the second magnet and the first magnet, the movable rod will be driven to move to the side away from the rotating shaft, stretching the return spring at the same time. And through the connecting plate, the movable rod drives the first piston rod to move synchronously. At this time, air is supplemented into the oxygenation cylinder through the one-way intake pipe. As the rotating shaft rotates, when the second magnet gradually moves away from the first magnet, the elastic recovery of the return spring can drive the movable rod to return to its original position. At the same time, the first piston rod can compress the air inside the oxygenation cylinder, and pump the air into the purified pond water through the one-way exhaust pipe, thereby increasing the oxygen content in the pond water. And as the device moves, the oxygen can be more evenly distributed throughout the aquaculture pond, avoiding local hypoxia. At the same time, the rotating rod, rotating column and cleaning disc are driven to rotate synchronously by the rotating shaft, so that the deposited feces and silt are scattered and dispersed, which is convenient for pumping by the water pump, effectively preventing the accumulation of impurities at the bottom of the pond and improving the cleaning depth and efficiency.

[0023] The traveling component 2 is used according to aquaculture ponds of different sizes: when purifying the water body, the whole device can be placed on the water surface of the aquaculture pond, and the whole device is supported by the buoyancy of the buoyancy plates 21 in the water. The first motor 22 is electrically connected through an external controller. When cleaning the aquaculture pond, the first motor 22 can be started to drive the propeller 24 to rotate, so as to provide power for the device to move in the pond water. And through the setting of the buoyancy plates 21, it can be ensured that the drain pipe 11 is located above the water surface of the pond water, so as to facilitate the discharge of the filtered circulating water when purifying the pond water. By controlling the rotation speed of the propeller 24, the overall moving speed and traveling direction of the device can be realized, so as to be applicable to aquaculture ponds of different shapes, improve the scope of use, and the second motor 6 and the water pump 72 can be started simultaneously during the moving process to pump the pond water into the filtering component 5 for filtering, so as to realize the cleaning of the bottom wall of the aquaculture pond through the cleaning component 8, so as to realize the circulating purification of the water body.

[0024] Refer to Figure 4 、 Figure 7 、 Figure 8 and Figure 9, Further, the filtering component 5 includes a purification tank 51, which is fixedly connected to the upper end of the bearing tank 41. A filter plate 52 and a cleaning plate 54 are fixedly connected inside the purification tank 51. The upper end of the purification tank 51 is fixedly connected to the second motor 6. A rotating shaft 10 is provided inside the purification tank 51. One end of the second motor 6 is fixedly connected to the rotating shaft 10. The end of the rotating shaft 10 away from the second motor 6 vertically penetrates the side wall of the filter plate 52 and the support plate 3. The outer wall of the rotating shaft 10 is detachably connected to the cleaning plate 54. A second magnetic block 101 is fixedly connected to the outer wall of the rotating shaft 10 below the filter plate 52. A clamping seat 12 is fixedly connected to the end of the rotating shaft 10 away from the second motor 6; a liquid storage cavity 541 is formed inside the cleaning plate 54. A buoyancy ball 53 is provided at the upper end of the cleaning plate 54. An outer cylinder 55 is fixedly connected to the side wall of the cleaning plate 54.

A second piston rod 57 is slidably connected to the inner wall of the inner cylinder 56. One end of the second piston rod 57 penetrates the side wall of the outer cylinder 55 and is fixedly connected to the buoyancy ball 53.

[0025] Purification and cleaning of water body by the filtering component 5: During the use of the device, while the traveling component 2 drives the support plate 3 to move, the water pump 72 pumps the pool water inside the centralized tank 801 into the purification tank 51 through the water suction pipe 73 and the water inlet pipe 71. The water body is purified by the filter plate 52. At the same time, the brush on one side of the cleaning plate 54 is driven by the rotation of the rotating shaft 10 to clean the impurities attached to the surface of the filter plate 52, reducing the blockage of the filter plate 52 and ensuring the filtering effect. A number of grooves distributed in a circular array can be provided on the surface of the filter plate 52. While the filter plate 52 purifies the pool water itself, it can also collect and store the filtered impurities; With long-term purification and filtration, more impurities and biological flocs will accumulate on the surface of the filter plate 52. At this time, simply cleaning with the cleaning plate 54 may not be able to effectively clean. Therefore, when the filtration speed decreases, the liquid level of the pool water pumped into the purification tank 51 will gradually rise. When the water level is higher than the height of the buoyancy ball 53, the buoyancy ball 53 will be driven to rise by the buoyancy force. As the buoyancy ball 53 moves, the piston rod two 57 will be stretched and move upward. In addition, a liquid adding nozzle is provided on the surface of the cleaning plate 54. An appropriate concentration of chemical reagent is added into the internal storage cavity 541 through the liquid adding nozzle. The air inside the inner cylinder 56 is compressed by the piston rod two 57, and the compressed air is discharged into the gap between the outer cylinder 55 and the inner cylinder 56 through the ventilation hole 561. When one end of the piston rod two 57 is higher than the liquid discharge hole 562, the reagent is discharged into the purification tank 51 through the gas pressure. The cleaning plate 54 not only realizes the release of the reagent, but also evenly stirs it to accelerate the rapid decomposition of the biological flocs and improve the cleaning efficiency. In addition, common chemical agents include oxidants (such as hydrogen peroxide, potassium permanganate, etc.). These agents can destroy the structure of the biological flocs, decompose them into smaller particles, and then be removed by methods such as filtration or precipitation. At the same time, when using chemical agents, attention will be paid to the concentration and dosage of the agents to avoid adverse effects on the aquaculture water body and rainbow trout. In this way, the attached biological flocs are eliminated, the clogging situation is reduced, and the number of manual cleanings is reduced. The filter plate 52 is detachably connected to the purification tank 51 for easy dumping of the impurities it collects. The filter plate 52 can be made of stainless steel, which has certain corrosion resistance and high mechanical strength, and can withstand a certain amount of water pressure and water flow impact, ensuring the service life and stability of the filter plate 52.

[0026] Further, the purification component 13 includes a bearing cylinder 131. The outer wall of the bearing cylinder 131 is fixedly connected to the inner wall of the purification tank 51. The bearing cylinder 131 is located below the filter plate 52. A fixed cylinder 132 is fixedly connected to the inner wall of the bearing cylinder 131. The fixed cylinder 132 is rotatably connected to the outer wall of the rotating shaft 10. A number of drain holes 134 are arranged in a circumferential array on the outer wall of the bearing cylinder 131. A number of spiral support plates 133 are arranged in a circumferential array inside the bearing cylinder 131. The two ends of the spiral support plate 133 are respectively fixedly connected to the inner wall of the bearing cylinder 131 and the outer wall of the fixed cylinder 132.

[0027] Treatment of the filtered pond water by the purification component 13: When the pond water passes through the filter plate 52 and then drops into the interior of the bearing cylinder 131, and after being purified by the spiral supporting plate 133, it flows to the bottom of the bearing cylinder 131 and finally drains into the interior of the bearing box 41 through the drain hole 134. The spiral supporting plate 133 is provided to guide the water flow to spiral downwards. This special flow pattern can extend the residence time of the water flow in the component, enabling the water to have more sufficient contact with the internal structure. In addition, the spiral supporting plate 133 can be made of polypropylene (PP), polyethylene (PE), etc., but is not limited thereto, and can be reasonably selected according to the actual use situation and production cost. Polypropylene has strong chemical stability, is resistant to acid and alkali corrosion, and is not easily eroded in the aquaculture pond water, and can be used for a long time. Its surface can be roughened to increase the surface area, facilitating the attachment of microorganisms to form a biofilm. At the same time, the polypropylene material is relatively light in weight. After being made into a spiral structure, the resistance to water flow is small, and it will not overly impede the spiral flow of the water flow, allowing the water flow to pass through smoothly, ensuring sufficient contact between the water flow and the microorganisms. Moreover, the fixed cylinder 132 can also serve as a carrier for microorganism attachment, making its surface rough to allow beneficial microorganisms such as nitrifying bacteria to attach and grow in large numbers to form a biofilm. When the water flow passes through, the microorganisms on the biofilm can decompose and transform harmful substances such as ammonia nitrogen and nitrite in the water, achieving biological purification. Then, the pond water with pollutants slowly passes through, providing sufficient time for microorganisms to degrade the pollutants. And the above chemical reagents can not only decompose the biological flocs, reducing their blockage of the filter plate, but also enable the water flow to pass through the purification component 13 more smoothly. This can make the microorganisms in the purification component 13 have sufficient contact with the water body, providing better conditions for microorganisms to degrade pollutants. For example, after using hydrogen peroxide to decompose the biological flocs, the suspended impurities in the water body decrease, and the contact area between the microorganisms and the pollutants increases, which is conducive to the microorganisms to play a degradation role. At the same time, some chemical reagents have a bactericidal and disinfection effect, which can inhibit the growth of harmful microorganisms and prevent them from competing with the beneficial microorganisms in the purification component 13 for nutrients and living space, thus ensuring the normal growth and metabolism of the beneficial microorganisms and maintaining their degradation ability.

[0028] Refer to Figures 2 - 5, further; the oxygenation component 4 includes a bearing box 41, the bearing box 41 is fixedly connected to the upper side wall of the support plate 3, the side wall of the bearing box 41 is fixedly connected with an oxygenation cylinder 45, there are two oxygenation cylinders 45, and the two oxygenation cylinders 45 are symmetrically distributed about the center line of the bearing box 41. The side wall of the bearing box 41 is provided with a one-way intake pipe 42, the one-way intake pipe 42 is communicated with one end of the oxygenation cylinder 45, the other end of the oxygenation cylinder 45 is piston-connected with a first piston rod 441, the first piston rod 441 is arranged in a "T" shape, and the outer wall of the oxygenation cylinder 45 is fixedly connected with a number of one-way exhaust pipes 46 distributed in a linear array; the oxygenation component 4 further includes a connecting plate 44 and a movable rod 47, one side of the connecting plate 44 is fixedly connected to the end of the first piston rod 441 located outside the oxygenation cylinder 45, the side wall of the connecting plate 44 is fixedly connected to one end of the movable rod 47, the other end of the movable rod 47 penetrates through the side wall of the bearing box 41, the end of the movable rod 47 far from the connecting plate 44 is fixedly connected with a first magnet 471, and a return spring 43 is sleeved on the outer wall of the movable rod 47. The two ends of the return spring 43 are respectively fixedly connected to the connecting plate 44 and the side wall of the bearing box 41.

[0029] Increase in oxygen content of the purified water body by the oxygenation component 4: While the motor two 6 drives the rotation of the rotating shaft 10, it can drive the magnet two 101 to rotate synchronously. The magnetism of the end of the magnet two 101 far from the rotating shaft 10 is the same polarity as the end of the magnet one 471 close to the rotating shaft 10. Therefore, based on the principle of like poles repelling each other, when the magnet two 101 gradually approaches the magnet one 471, a mutual force will be generated, which will drive the movable rod 47 to move to the side away from the rotating shaft 10, stretching the return spring 43 at the same time. And through the connecting plate 44, the movable rod 47 drives the piston rod one 441 to move synchronously. At this time, as the piston rod one 441 moves, the pressure inside the oxygenation cylinder 45 will change, and then air will be replenished into the oxygenation cylinder 45 through the one-way intake pipe 42. As the rotating shaft 10 rotates, when the magnet two 101 gradually moves away from the magnet one 471, the force between the two will gradually weaken or disappear. At this time, the elastic recovery of the return spring 43 can drive the movable rod 47 to return to its original position. At the same time, the piston rod one 441 can squeeze the air inside the oxygenation cylinder 45, and the air is squeezed into the purified pool water at the bottom of the bearing cylinder 131 through the one-way exhaust pipe 46. And the bottom end of the drain pipe 11 is higher than the water surface of the pool water to ensure the discharge of the purified water body. In this reciprocating motion mode, air can be effectively filled into the purified water body. When the outside air is pumped into the water, the air will be dispersed in the water in the form of bubbles. When the bubbles contact the water, oxygen will diffuse from the bubbles into the water, and gases such as carbon dioxide in the water will diffuse into the bubbles, thus increasing the oxygen content of the pool water. And when pumping air into the water, it will cause the flow and disturbance of the water body. This disturbance can break the gas-liquid interface on the water surface, increase the gas-liquid contact area, and is conducive to gas exchange. At the same time, as the device moves, the oxygen can be more evenly distributed throughout the aquaculture pond, avoiding local oxygen deficiency.

A sliding block 92 is fixedly connected to the inner wall of the adjusting cylinder 9. The sliding block 92 is slidably connected with the limiting sliding groove 141. One end of the adjusting cylinder 9 away from the central box 801 is fixedly connected to a plug connector 91 that cooperates with the clamping seat 12.

[0031] Cleaning of the bottom wall of the aquaculture pond by the cleaning component 8: During the purification of the aquaculture pond water, it can be selectively used according to the needs. When simultaneous purification and cleaning are required, the adjusting cylinder 9 can be pulled to make the plug connector 91 at one end of the adjusting cylinder 9 be clamped and fixed with the clamping seat 12 at one end of the rotating shaft 10. The fixing method between the two is not limited to this one, and magnetic attraction, snap-fasteners and other fixing methods can also be used for connection. When the two are fixedly connected to each other, through the limiting sliding between the sliding block 92 and the limiting sliding groove 141, it can be ensured that the rotating rod 14 rotates together while the adjusting cylinder 9 rotates. Therefore, during the movement of the support plate 3 through the traveling component 2, the motor two 6 not only drives the rotating shaft 10 to rotate, but also synchronously drives the adjusting cylinder 9 and the rotating rod 14 to rotate while driving the magnetic block two 101 to move through the rotating shaft 10. The rotating rod 14 is fixedly connected to one of the rotating columns 805, and the multiple rotating columns 805 are meshed and driven by the transmission chain 804. Therefore, the multiple rotating columns 805 are synchronously driven to rotate by the rotating rod 14, thereby driving the multiple cleaning discs 802 to rotate. Brushes are installed at the bottom of the cleaning discs 802. The bristles of these brushes are of appropriate length and hardness and can effectively penetrate into the sludge. Through the mutual friction between the brushes and the pond bottom, the deposited feces and sludge can be scattered and dispersed, so as to be easily pumped by the water pump 72 and enter the inside of the central box 801 through the water inlet slot holes 803, so that the feces and sludge are more easily collected. For some sludge with greater viscosity, the role of the brushes is more obvious, which can effectively prevent the accumulation of impurities at the bottom of the pond and improve the cleaning efficiency; In addition, when only the pool water needs to be purified, the connection between the plug connector 91 and the clamping seat 12 can be disconnected, and the position of the cleaning component 8 in the pool water can be adjusted by the electric telescopic rod 1 to prevent the cleaning component 8 from scraping the pool bottom. During the movement of the device, only the pool water can be pumped by the pumping component 7 and the cleaning component 8 without cleaning the pool bottom, so as to realize the independent use of the oxygenation component 4, the filtering component 5 and the purification component 13. During the use process, due to the disturbance of the pool water part, the surrounding fish will swim around without being disturbed.

[0032] It should be noted that the specific model specifications of the motor and the water pump need to be selected according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
