Description

Technical Field

[0001] The invention relates to the technical field of plug flow aeration, in particular to a plug flow aeration device for catfish breeding water. Background Art

[0002] Catfish, also known as catfish and bearded catfish, is a common freshwater fish. It has become a fine variety favored by breeders in recent years because of its fast growth, wide diet and few diseases. In order to successfully breed catfish, it is very important to understand and master its growth habits and feeding conditions. Catfish feed can be a combination of animal feed and plant feed. In the early stage of fry cultivation, animal feed should be the main focus for intensive cultivation. As the fish grows, some plant feed should be gradually added to achieve a combination of animal and plant feed.

[0003] Oxygenation is an important technology in aquaculture, which can increase the dissolved oxygen content in water and promote the growth of aquatic organisms. Three methods of mechanical oxygenation, chemical oxygenation and biological oxygenation are introduced. Plug flow aeration is a type of mechanical oxygenation.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] The catfish breeding water body plug flow aeration device disclosed by the present invention is mainly used in the scenario where the general catfish breeding plug flow aeration equipment cannot collect the residual fish food in the fish pond during the aeration and oxygenation process, resulting in the waste of fish food and even the pollution of the water body in the fish pond, thereby reducing the quality of catfish cultured in the fish pond.

[0040] Reference Figure 1 — Fig. 9 A catfish breeding water body push flow aeration device comprises a floating boat 1, an air pump 2 is arranged on the top of the floating boat 1, an air inlet 14 is arranged on the upper surface of the air pump 2, a connecting rope 3 is fixedly connected to one side of the floating boat 1, an air pipe 4 is plugged into a position near the connecting rope 3 on one side of the floating boat 1, a connecting box 5 is fixedly connected to the other end of the air pipe 4, and a connecting rod 6 is slidably connected to the center position of the connecting box 5,

[0041] A propulsion mechanism is installed at the bottom of the air pump 2 inside the floating ship 1, and the propulsion mechanism is used to propel the floating ship 1 forward;

[0042] A filtering mechanism is installed inside the floating boat 1 near the propulsion mechanism, and the filtering mechanism is used to filter fish food in the water;

[0043] A collecting mechanism is installed inside one end of the floating boat 1, and the collecting mechanism is used to collect excess fish food in the water;

[0044] An adjustment mechanism is installed on the outer walls of both sides of one end of the floating vessel 1, and the adjustment mechanism is used to adjust the collection mechanism;

[0045] A travel mechanism is installed on one side of the interior of the connection box 5, and the travel mechanism is used to adjust the radius of the floating ship 1 turning in the water;

[0046] A buoyancy fixing mechanism is installed on the top of the connection box 5, and the buoyancy fixing mechanism is used to connect the connection box 5 and the connection rod 6;

[0047] A slide rail mechanism is installed on the outer wall of the connecting rod 6, and the slide rail mechanism is used in conjunction with the fixing mechanism;

[0048] An anchoring mechanism is installed at the bottom of the connecting rod 6, and the anchoring mechanism is used to fix the position of the connecting box 5 floating on the water surface.

[0049] The propulsion mechanism includes a water pipe 28 inserted into the bottom of the air pump 2, the bottom end of the water pipe 28 is fixedly connected to a tee 29, one side of the tee 29 is fixedly connected to an oxygenation cylinder 9, and the other side of the tee 29 is connected to the air pipe 4.

[0050] In this embodiment, the anchor plate 8 is placed below the connection box 5, and the floating boat 1, the connection box 5 and the anchor plate 8 are put into the fish pond by a boat. The floating boat 1 is separated from the connection box 5 by a certain distance, and the connection rope 3 is tightened. The floating boat 1 floats on the water surface due to buoyancy, and the air pump 2 is started. The air pump 2 inhales a large amount of air through the air inlet 14, and discharges the air into the air pipe 4 and the aeration cylinder 9 respectively through the water guide pipe 28 and the three-way device 29. The air and part of the water inside the aeration cylinder 9 are discharged together through the tail of the aeration cylinder 9, and a large amount of bubbles are generated in the water. The floating boat 1 slides forward in the fish pond through the reverse thrust effect. Due to the restraint of the connection rope 3, the floating boat 1 makes a circular motion around the connection box 5, and the floating boat 1 continuously circles in the fish pond, and the aeration cylinder 9 continuously generates bubbles, so that the oxygen content of the water in the fish pond where the floating boat 1 passes is continuously increased, which has the effect of increasing oxygen to the fish pond entity in a large range.

[0051] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4In a preferred embodiment, the filtering mechanism includes a connecting shell 18 fixedly connected to the bottom edge of one end of the floating boat 1, a collecting box 27 is fixedly connected to one side of the connecting shell 18, a triangular filter 16 is fixedly connected to the bottom surface of the collecting box 27, a front surface of the triangular filter 16 is provided with a plurality of filtering holes 17, a rear surface of the triangular filter 16 is plugged with a plurality of drainage pipes 15, and fish food barrels 11 are respectively plugged into positions near the collecting box 27 on both sides of the floating boat 1, and a toggle wheel 10 is rotatably connected to the inside of the fish food barrel 11, and a plurality of toggle bars 30 are respectively provided on the outer walls around the toggle wheel 10.

[0052] In this embodiment, the collected fish food enters the collecting box 27. Due to the effect of the water flow, the fish food in the collecting box 27 floats backward and is blocked by the triangular filter 16. The filtering effect of the triangular filter 16 allows water to flow through and the fish food is filtered out. The filtered water is discharged through the drain pipe 15, which has the effect of pushing the floating boat 1 to slide.

[0053] Furthermore, part of the water together with the fish food is discharged through the fish food tube 11, and the flowing water drives the toggle wheel 10 to rotate. The rotation of the toggle wheel 10 allows the fish food to be evenly scattered into the water, which has the effect of slowly and evenly throwing the fish food, so that the fish food in the water is not wasted and the water body is cleaner.

[0054] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the collecting mechanism includes a collecting plate 23 rotatably connected to the bottom edge of one end of the floating ship 1, the upper surface of the collecting plate 23 is rotatably connected to the second rotating roller 22, and connecting shafts are rotatably connected to the inner walls of both sides of the floating ship 1, one end of the connecting shaft extends out of one side of the floating ship 1, and the other end of the connecting shaft is fixedly connected to the first rotating roller 19, a conveyor belt 21 is arranged between the first rotating roller 19 and the second rotating roller 22, and a plurality of conveyor bars 20 are respectively arranged on the outer walls of the conveyor belt 21, and a water wheel 12 is fixedly connected to one end of the connecting shaft extending out of the floating ship 1.

[0055] In this embodiment, catfish are fed artificially by scattering fish food into the water. After the catfish eat, part of the fish food floats in the water, so that the fish food placement position is within the movement range of the floating boat 1. During the continuous rotation of the floating boat 1, the collecting plate 23 continuously collects the remaining fish food in the water onto the surface of the collecting plate 23. The continuous movement of the floating boat 1 drives the water wheel 12 to rotate, so that the first rotating roller 19 and the second rotating roller 22 start to rotate, so that the fish food on the surface of the collecting plate 23 is transmitted to the inside of the floating boat 1, thereby achieving the effect of collecting the remaining fish food.

[0056] Reference Figure 1 , Figure 2, Figure 3 and Figure 4 In a preferred embodiment, the adjustment mechanism includes two buoyancy blocks 13 slidably connected to the outer walls of both sides of the floating ship 1 near the water wheel 12, and the tops of the buoyancy blocks 13 are respectively fixedly connected to floating plates 26, one side of the floating plates 26 is rotatably connected to a connecting plate 25, one side of the connecting plate 25 is rotatably connected to a lifting rod 24, and the lifting rod 24 is rotatably connected to one side of the collecting plate 23.

[0057] In this embodiment, during the sliding process of the floating boat 1, the floating boat 1 will float up and down. During the floating process of the floating boat 1, the buoyancy block 13 slides downward due to the buoyancy, driving the floating plate 26 and the connecting plate 25 to slide downward, so that the lifting rod 24 drives the collecting plate 23 to flip downward, so that the opening between the floating boat 1 and the connecting rope 3 becomes larger, which does not affect the effect of collecting fish food. During the sinking process of the floating boat 1, the buoyancy block 13 slides upward due to the buoyancy, driving the floating plate 26 and the connecting plate 25 to slide upward, so that the lifting rod 24 drives the collecting plate 23 to flip upward, so that the opening between the floating boat 1 and the connecting rope 3 becomes smaller, preventing the opening between the floating boat 1 and the connecting rope 3 from being too large, thereby reducing the water resistance.

[0058] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 In a preferred embodiment, the travel mechanism includes a rope winding roller 31 rotatably connected to the inner wall of one side of the connecting box 5, a handle 32 is fixedly connected to the top of the rope winding roller 31, one end of the connecting rope 3 is wound around the rope winding roller 31, one end of the air pipe 4 extends into the interior of the connecting box 5, and the end of the air pipe 4 extending into the interior of the connecting box 5 is fixedly connected to a hard pipe 33, the top of the connecting rod 6 is rotatably connected to a connecting block 34, the connecting block 34 is fixedly connected to the other end of the hard pipe 33, the bottom of the connecting block 34 is fixedly connected to an aeration pipe 48, and a plurality of exhaust holes 49 are provided on the outer walls around the aeration pipe 48.

[0059] In this embodiment, by rotating the handle 32, the rope roller 31 is driven to rotate, so that the length of the connecting rope 3 wrapped around the outside of the connecting box 5 becomes longer or shorter, so as to adjust the distance between the floating vessel 1 and the connecting box 5, thereby adjusting the range of movement of the floating vessel 1.

[0060] What needs to be explained more is that another part of the air in the three-way device 29 enters the hard tube 33 through the air pipe 4, and the air embryo is discharged into the connecting rod 6 through the connecting block 34, the oxygenation pipe 48 and the exhaust hole 49, and is discharged through the multiple discharge holes 47 on the connecting rod 6, so that the fish pond can be directly oxygenated from the water surface to the bottom of the water, thereby achieving the effect of oxygenating the water at the bottom of the fish pond.

[0061] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 In a preferred embodiment, the buoyancy fixing mechanism includes a rotating box 35 slidably connected to the inner wall at the top of the connecting box 5, and a plurality of mounting frames 40 are fixedly connected to the bottom of the inner wall of the rotating box 35. A rectangular groove is provided on one side of the mounting frame 40, and a slider 39 is slidably connected inside the rectangular groove. A spring 38 is fixedly connected to one end of the slider 39, and a connecting gear 37 is rotatably connected to one side of the slider 39. A mounting plate is fixedly connected to the upper surface of the mounting plate, and a rack 41 is slidably connected to one end edge of the rack 41. A tooth head is fixedly connected to the bottom of the inner wall of the connecting box 5, and a water tank 36 is fixedly connected to the water tank 36.

[0062] The slide rail mechanism includes a plurality of track teeth 46 arranged on the outer wall of the connecting rod 6 from the top end to the bottom end, and a plurality of discharge holes 47 are arranged on the outer wall of the connecting rod 6 from the top end to the bottom end.

[0063] In this embodiment, when the anchor plate 8 begins to sink, one end of the rack 41 is against the mounting frame 40, so that when the connecting rod 6 slides downward, the connecting gear 37 cannot rotate, so that the connecting gear 37 drives the tee 29 to squeeze the spring 38, so that the slider 39 slides to one side, thereby causing the connecting rod 6 to slide downward. In the process of the connecting rod 6 sliding downward, water enters the interior of the connecting rod 6 through the multiple discharge holes 47 on the connecting rod 6. Since there is a section of smooth outer wall at the bottom of the connecting rod 6 without the discharge hole 47, this section of smooth outer wall continues to slide downward until it breaks away from the opening at the top edge of the water tank 36. The water inside the connecting rod 6 can enter the water tank 36 through the discharge hole 47, the water tank 36 begins to be filled with water, and the connecting box 5 begins to sink.

[0064] Furthermore, due to the small diameter of the discharge hole 47 and the slow filling speed, after the anchor plate 8 contacts the bottom of the fish pond, the connecting rod 6 is fixed and the waterline of the connecting box 5 begins to rise, and the connecting box 5 slides down relative to the connecting rod 6, and the connecting gear 37 engages with the track tooth 46, and the connecting gear 37 rolls on the surface of the connecting rod 6. The connecting gear 37 engages with the rack 41, driving the rack 41 to slide to one side of the connecting rod 6, so that the tooth head of a section of the rack 41 is stuck in one of the track teeth 46 on the outer wall of the connecting rod 6. Since the rack 41 is designed to be symmetrical on both sides, the rack 41 clamps the connecting rod 6. Since the buoyancy is less than the gravity, the gravity of the connecting box 5 fixes the position of the connecting box 5 and the connecting rod 6, so that the connecting box 5 is stably fixed on the water surface directly above the anchor plate 8. At this time, a part of the connecting box 5 is immersed in water and cannot move horizontally or up and down.

[0065] Reference Figure 1 , Figure 7 , Figure 8 and Fig. 9In a preferred embodiment, the anchoring mechanism includes a track tooth 46 fixedly connected to the bottom of the connecting rod 6, the bottom of the track tooth 46 is rotatably connected to a ball shell 45, the bottom of the ball shell 45 is fixedly connected to an anchor plate 8, and a plurality of buoyancy cylinders 7 are fixedly connected to the edges of the upper surface of the anchor plate 8, an exhaust hole 42 is provided at the top of the buoyancy cylinder 7, and a water inlet hole 43 is provided at the bottom of the buoyancy cylinder 7.

[0066] One end of the oxygen enrichment cylinder 9 extends out of the rear of the floating boat 1, the lifting rod 24 passes through the top outside of the floating boat 1, the lifting rod 24 is slidably connected to the floating boat 1, the other end of the spring 38 is fixedly connected to the mounting frame 40, the rotating box 35 is slidably connected to the connecting rod 6, the connecting gear 37 is meshed with the rack 41, the track tooth 46 is meshed with the connecting gear 37, and the tooth head can be stuck between the two track teeth 46.

[0067] In this embodiment, the anchor plate 8 at the bottom of the connection box 5 begins to sink first, and the buoyancy tube 7 on the anchor plate 8 begins to take in water due to the bottom water inlet hole 43, and the exhaust hole 42 is exhausted, the buoyancy of the anchor plate 8 is reduced, and the anchor plate 8 begins to sink until the anchor plate 8 contacts the bottom of the fish pond. Since the anchor plate 8 has a large mass, it can be used as an anchor point to fix the position of the connection box 5 on the water surface, thereby playing the role of anchoring the connection box 5.

[0068] Working principle: When in use, the anchor plate 8 is placed under the connection box 5, and the floating boat 1, the connection box 5 and the anchor plate 8 are put into the fish pond by a boat. The floating boat 1 is separated from the connection box 5 by a certain distance, so that the connection rope 3 is tightened, and the floating boat 1 floats on the water surface due to buoyancy. The anchor plate 8 at the bottom of the connection box 5 begins to sink first, and the buoyancy cylinder 7 on the anchor plate 8 begins to take in water due to the bottom water inlet hole 43, and the exhaust hole 42 is exhausted. The buoyancy of the anchor plate 8 is reduced, and the anchor plate 8 begins to sink until the anchor plate 8 touches the bottom of the fish pond. Due to the large mass of the anchor plate 8, it can be used as an anchor point to fix the position of the connection box 5 on the water surface, thereby anchoring the connection box 5, when the anchor plate 8 starts to sink, one end of the rack 41 abuts against the mounting frame 40, so that when the connecting rod 6 slides downward, the connecting gear 37 cannot rotate, so that the connecting gear 37 drives the tee 29 to squeeze the spring 38, so that the slider 39 slides to one side, thereby sliding the connecting rod 6 downward. During the sliding process of the connecting rod 6, water enters the interior of the connecting rod 6 through the multiple discharge holes 47 on the connecting rod 6. Since there is a smooth outer wall at the bottom of the connecting rod 6 without the discharge hole 47, this smooth outer wall keeps sliding downward until it is separated from the opening at the top edge of the water tank 36, and the water inside the connecting rod 6 can be discharged through the discharge hole 47. The discharge hole 47 enters the water tank 36, and the water tank 36 begins to be filled with water, and the connection box 5 begins to sink. Due to the small diameter of the discharge hole 47, the speed of water filling is slow. After the anchor plate 8 contacts the bottom of the fish pond, the connecting rod 6 is fixed, and the waterline of the connection box 5 begins to rise. The connection box 5 slides down relative to the connecting rod 6, and the connecting gear 37 is meshed with the track gear 46. The connecting gear 37 rolls on the surface of the connecting rod 6. The connecting gear 37 is meshed with the rack 41, driving the rack 41 to slide to one side of the connecting rod 6, so that the tooth head of a section of the rack 41 is stuck in one of the track teeth 46 on the outer wall of the connecting rod 6. Since the rack 41 is a bilaterally symmetrical design, the rack 41 is stuck in the connection Rod 6, because the buoyancy is less than the gravity, the gravity of the connection box 5 makes the position of the connection box 5 and the connection rod 6 fixed, so that the connection box 5 is stably fixed on the water surface just above the anchor plate 8. At this time, a part of the connection box 5 is immersed in the water and cannot move horizontally and up and down. By turning the handle 32, the rope roller 31 is driven to rotate, so that the length of the connection rope 3 wrapped around the outside of the connection box 5 becomes longer or shorter, so as to adjust the distance between the floating ship 1 and the connection box 5, and play the effect of adjusting the range of activities of the floating ship 1. Start the air pump 2, so that the air pump 2 inhales a large amount of air through the air inlet 14, and discharges the air into the air pipe 4 and the oxygen cylinder 9 respectively through the water guide pipe 28 and the three-way device 29.The air and part of the water inside the aeration cylinder 9 are discharged together through the tail of the aeration cylinder 9, a large number of bubbles are generated in the water, and the floating boat 1 slides forward in the fish pond through the reverse thrust effect. Due to the restraint of the connecting rope 3, the floating boat 1 makes a circular motion around the connecting box 5, and the floating boat 1 continuously circles in the fish pond, and bubbles are continuously generated through the aeration cylinder 9, so that the oxygen content of the water in the range where the floating boat 1 passes through the fish pond is continuously increased, which has the effect of increasing oxygen to the fish pond entity in a large range. Another part of the air enters the hard pipe 33 through the air pipe 4, and the air embryo is discharged into the connecting rod 6 through the connecting block 34, the aeration pipe 48 and the exhaust hole 49. The discharge hole 47 discharges water, so that the fish pond can be directly oxygenated from the water surface to the bottom of the water, which has the effect of increasing oxygen to the water body at the bottom of the fish pond. When feeding catfish artificially, fish food is scattered into the water, and some of the fish food floats in the water after the catfish eats, so that the fish food delivery position is within the movement range of the floating boat 1. In the process of the floating boat 1 continuously rotating, the collecting plate 23 continuously collects the remaining fish food in the water onto the surface of the collecting plate 23. The continuous movement of the floating boat 1 drives the water wheel 12 to rotate, so that the first rotating roller 19 and the second rotating roller 22 start to rotate, so that the fish food on the surface of the collecting plate 23 is transmitted to the inside of the floating boat 1, which has the effect of collecting the remaining fish food. The collected fish food enters the collecting box 27. Due to the effect of the water flow, the fish food in the collecting box 27 floats backward and is blocked by the triangular filter 16. The filtering effect of the triangular filter 16 allows water to flow through, and the fish food is filtered out. The filtered water is discharged through the drain pipe 15, which has the effect of pushing the floating boat 1 to slide. Part of the water and the fish food are discharged through the fish food tube 11. The flowing water drives the toggle wheel 10 to rotate. The rotation of the toggle wheel 10 allows the fish food to be evenly scattered into the water, which has the effect of slowly and evenly throwing the fish food, so that the fish food in the water is not wasted, and the water body is cleaner. In the process of the floating boat 1 sliding, the floating boat 1 will 1 floats up and down. During the process of floating boat 1 floating up, buoyancy block 13 slides downward due to buoyancy, driving floating plate 26 and connecting plate 25 to slide downward, so that lifting rod 24 drives collecting plate 23 to flip downward, making the opening between floating boat 1 and connecting rope 3 larger, which does not affect the effect of collecting fish food. During the process of floating boat 1 sinking, buoyancy block 13 slides upward due to buoyancy, driving floating plate 26 and connecting plate 25 to slide upward, so that lifting rod 24 drives collecting plate 23 to flip upward, making the opening between floating boat 1 and connecting rope 3 smaller, preventing the opening between floating boat 1 and connecting rope 3 from being too large, and playing the effect of reducing water resistance.
