DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0032] Example 1: Reference Figure 1-Figure 5A water purification device based on land-based barrel pool aquaculture includes a barrel pool 1, a rotating mechanism is provided in the middle of the barrel pool 1, and a mounting plate 2 is provided below the rotating mechanism, a plurality of connecting columns 12 are fixedly connected to the bottom of the mounting plate 2, and a plurality of connecting columns 12 are fixedly connected to the bottom ends of the plurality of connecting columns 12 with a circular runway-type track 14 in an inclined state, a chain 11 is provided directly below the circular runway-type track 14, and a plurality of vertical parallel mechanisms are provided at equal distances on the top of the chain 11, the vertical parallel mechanisms can contact the outer wall of the bottom of the circular runway-type track 14, and a pushing plate 6 is installed on each of the vertical parallel mechanisms, a driving mechanism is provided on the mounting plate 2, and the driving mechanism can make the chain 11 move, and the chain 11 is directly below An L-shaped scraper 7 is provided, and a plurality of connecting columns 10 are fixedly connected between the top of the L-shaped scraper 7 and the bottom of the mounting plate 2. The lower end of the L-shaped scraper 7 is on the same side as the drooping end of the circular runway-type track 14, and the lower end of the L-shaped scraper 7 is in contact with the bottom inner wall of the barrel pool 1. When the bottom inner wall of the barrel pool 1 needs to be cleaned, the rotating mechanism rotates the mounting plate 2 at an extremely low speed (1-2 rpm). Since the lower end of the L-shaped scraper 7 at the bottom of the mounting plate 2 is in contact with the bottom inner wall of the barrel pool 1, the lower end of the L-shaped scraper 7 can scrape off impurities such as feces attached to the bottom inner wall of the barrel pool 1, and the scraped feces and other impurities will gather at the position where the lower end of the L-shaped scraper 7 contacts the bottom inner wall of the barrel pool 1. However, when the rotation When the mechanism rotates the mounting plate 2 at an extremely low speed (1-2 rpm), a weak laminar flow can occur in the water in the barrel pool 1, causing the flow velocity at the bottom of the barrel of the barrel pool 1 to be close to zero (viscous boundary layer effect). The flow velocity increases as it goes upwards, and the flow velocity in the central area is low, while the flow velocity at the edge is high (the linear velocity increases with the radius during rotation), thereby causing the feces and other impurities at the lower end of the L-shaped scraper 7 to move toward the inner wall of the barrel pool 1. However, in this process, the driving mechanism will move the chain 11, and the chain 11 will move with the multiple push plates 6 on its top. When the push plate 6 moves to the lower end of the circular runway track 14, under the action of the vertical parallel mechanism, the push plate 6 will be perpendicular to the horizontal plane. , and the vertical push plate 6 contacts the outer wall of the lower end of the L-shaped scraper 7. Driven by the chain 11, the vertical push plate 6 moves toward the rotating shaft 5, thereby preventing the feces and other impurities at the lower end of the L-shaped scraper 7 from moving toward the inner wall of the barrel pool 1, and at the same time pushing the feces and other impurities to move toward the rotating shaft 5, so that the cleaned feces and other garbage impurities are gathered in the central part of the barrel pool 1, which is convenient for subsequent processing. When the push plate 6 moves to the upturned end of the circular runway-type track 14, the vertical parallel mechanism rotates the push plate 6 by 90 degrees to make it parallel to the horizontal plane, avoiding disturbing the water during movement. At the same time, the surface of the push plate 6 can be washed during movement to prevent garbage from adhering to its surface.During this process, concentric ripples will form on the water surface of the barrel pool 1. The ripple disturbance will break the tension of the water-air interface, accelerating the dissolution of oxygen in the air into the water. At the same time, the water flow driven by the ripples can prevent local water stagnation, reduce the accumulation of harmful substances (such as ammonia nitrogen), and reduce the risk of fish disease.

[0033] As a further solution in the present invention, the rotating mechanism includes a mounting frame 3, which is fixedly connected to the top of the barrel pool 1, and a rotating shaft 5 is rotatably connected to the middle of the mounting frame 3. A driving motor 4 is provided at the top of the rotating shaft 5, and the mounting plate 2 is fixedly connected to the bottom end of the rotating shaft 5. The driving motor 4 can rotate the rotating shaft 5, thereby causing the mounting plate 2 at the bottom of the rotating shaft 5 to rotate synchronously.

[0034] As a further solution in the present invention, the driving mechanism includes two rotating shafts 29, which are respectively arranged on both sides of the mounting plate 2, and the bottom ends of the rotating shafts 29 are fixedly connected to sprockets 16, which are engaged with the chain 11. The top of one of the rotating shafts 29 is fixedly connected to a driving wheel 8, and the outer wall of the driving wheel 8 is provided with anti-slip grooves. The driving wheel 8 is tightly against the inner wall of the barrel pool 1. When the rotating shaft 15 rotates with the mounting plate 2, the outer wall of the driving wheel 8 is tightly against the inner wall of the barrel pool 1, which can make the driving wheel 8, and thus the rotating shaft 29 below the driving wheel 8, rotate with the sprocket 16, so that the chain 11 engaged with it moves.

[0035] As a further solution in the present invention, the vertical parallel mechanism includes an L-shaped plate 15, which is fixedly connected to the outer wall of the outer link of the chain 11, and one side of the L-shaped plate 15 is rotatably connected to the rotating shaft three 13, the pushing plate 6 is fixedly connected to the outer wall of one end of the corresponding rotating shaft three 13, and the other end of the rotating shaft three 13 is fixedly connected to the gear one 20.

[0036] As a further solution of the present invention, the top of the L-shaped plate 15 is slidably connected to a guide rod, and the top of the guide rod is fixedly connected to a pressing plate 19, a connecting spring 17 is provided between the bottom outer wall of the pressing plate 19 and the top outer wall of the L-shaped plate 15, and the top of the pressing plate 19 contacts the bottom outer wall of the circular runway track 14, and a notch is provided on the outer wall of the guide rod facing the gear 1 20, and a rack 18 is fixedly connected in the notch, and the rack 18 is meshed with the corresponding gear 1 20. When the chain 11 moves with multiple L-shaped plates 15, the pressing plate 19 will move along the bottom of the circular runway track 14. When the pressing plate 19 moves from the upturned end of the circular runway track 14 to the top of the circular runway track During the process of the track 14 drooping, the pressing plate 19 will be subjected to pressing force, causing the connecting spring 17 to be compressed. At this time, the guide rod will move downward, because the rack 18 in the guide rod groove is engaged with the gear 1 20 on the rotating shaft 3 13, thereby causing the rotating shaft 3 13 to rotate with the push plate 6. When the pressing plate 19 contacts the outer wall of the bottom of the drooping end of the circular runway type track 14, the push plate 6 is rotated ninety degrees and perpendicular to the horizontal plane. When the pressing plate 19 moves from the drooping end of the circular runway type track 14 to the upturned end of the circular runway type track 14, the guide rod is moved upward under the action of the rebound force of the connecting spring 17, thereby enabling the vertical push plate 6 to rotate to be parallel to the horizontal plane.

[0037] Working principle: When the inner wall of the bottom of the barrel pool 1 needs to be cleaned, the rotating mechanism rotates the mounting plate 2 at an extremely low speed (1-2 rpm). Since the lower end of the L-shaped scraper 7 at the bottom of the mounting plate 2 contacts the inner wall of the bottom of the barrel pool 1, the lower end of the L-shaped scraper 7 can scrape off the feces and other impurities attached to the inner wall of the bottom of the barrel pool 1, and the scraped feces and other impurities will gather at the contact point between the lower end of the L-shaped scraper 7 and the inner wall of the bottom of the barrel pool 1. However, when the rotating mechanism rotates the mounting plate 2 at an extremely low speed (1-2 rpm), it can The water in the barrel pool 1 will have a weak laminar flow, resulting in the flow velocity at the bottom of the barrel pool 1 close to zero (viscous boundary layer effect), the flow velocity increases as it goes upwards, and the flow velocity in the central area is low, while the flow velocity at the edge is high (the linear velocity increases with the radius during rotation), thereby causing the feces and other impurities at the lower end of the L-shaped scraper 7 to move to the inner wall of the barrel pool 1. However, in this process, the driving mechanism will move the chain 11, and the chain 11 will move with the multiple push plates 6 at its top. When the push plate 6 moves to the lower end of the circular runway track 14, Under the action of the vertical parallel mechanism, the push plate 6 is perpendicular to the horizontal plane, and the vertical push plate 6 contacts the outer wall of the lower end of the L-shaped scraper 7. As the chain 11 drives, the vertical push plate 6 moves toward the rotating shaft 5, thereby preventing the feces and other impurities at the lower end of the L-shaped scraper 7 from moving toward the inner wall of the barrel pool 1, and at the same time pushing the feces and other impurities to move toward the rotating shaft 5, so that the cleaned feces and other garbage impurities are gathered in the center of the barrel pool 1, which is convenient for subsequent processing. When the push plate 6 moves to the circular runway track When the upward end of the channel 14 is reached, the push plate 6 will be rotated ninety degrees by the action of the vertical parallel mechanism to make it parallel to the horizontal plane, so as to avoid disturbing the water during movement. At the same time, the surface of the push plate 6 can be flushed during movement to prevent garbage from adhering to its surface. In this process, concentric ripples will be generated on the water surface of the barrel pool 1. The ripple disturbance on the water surface will break the tension of the water-air interface and accelerate the dissolution of oxygen in the air into the water. At the same time, the water flow driven by the ripples can prevent local water stagnation, reduce the accumulation of harmful substances (such as ammonia nitrogen), and reduce the risk of fish disease.

[0038] Example 2: Reference Figure 6-Figure 7 , a water purification equipment based on land-based barrel pond aquaculture. Compared with Example 1, on the basis of Example 1, the outer walls on both sides of the top of the mounting frame 3 are fixedly connected with a fixing frame 21, and the fixing frame 21 is installed with a storage barrel 22. The storage barrel 22 contains fish feed that can float on the water surface, and a discharge pipe 29 is provided at the bottom of the storage barrel 22. The discharge pipe 29 is provided with an electric discharge valve 28. When the inner wall of the bottom of the barrel pond 1 is cleaned, the electric discharge valve 28 on the discharge pipe 29 is opened for a period of time, and the time can be automatically controlled. During the period when the electric discharge valve 28 is open, the fish feed will fall out at a uniform speed from the bottom of the discharge pipe 29.

[0039] As a further solution in the present invention, driving shafts 25 rotatably connected to the mounting bracket 3 are provided on both sides of the driving motor 4, and the bottom ends of the driving shafts 25 are fixedly connected to gear three 24, and the outer wall above the rotating shaft 5 is fixedly connected to gear two 23 meshing with gear three 24, and the top of the driving shaft 25 is fixedly connected to the turntable 33, and the outer wall on one side of the top of the turntable 33 is fixedly connected to a boss 32. When cleaning, the rotating shaft 5 will rotate with the gear two 23, because there are gear three 24 meshing with it on both sides of the gear two 23, so that the driving shaft 25 on the gear three 24 can rotate with the turntable 33.

[0040] As a further solution in the present invention, a swing shaft 30 is provided on one side of the turntable 33, which is rotatably connected to the mounting frame 3, and a swing plate 27 is fixedly connected to the top of the swing shaft 30. A rectangular through groove 31 is provided on one side of the swing plate 27, and a boss 32 is located in the rectangular through groove 31. A throwing plate 26 is fixedly connected to the outer wall of the bottom of the other side of the swing plate 27, and the middle part of the throwing plate 26 is directly below the bottom end of the discharge tube 29. Because the boss 32 on the turntable 33 is located in the rectangular through groove 31 of the swing plate 27, when the turntable 33 rotates with the boss 32, the swing plate 27 can swing. Because the throwing plate 26 at the bottom of the swing plate 27 is located below the discharge tube 29, the throwing plate 26 can slap the fish feed that falls from the discharge tube 29, thereby slapping the fish feed to a far distance. The fish feed can be thrown onto the water surface of the barrel pool 1, and the fish feed can be broken up when slapping to avoid clumping, which is convenient for fish to eat. At the same time, during the swinging process of the swinging plate 27, part of the fish feed will collide with the top of the swinging plate 27. Under the action of the impact force, this part of the fish feed can fall on the water surface around the mounting frame 3, so that through the cooperation with the throwing plate 26, the fish feed can be fully thrown onto the water surface, allowing the fish feed to float on the water surface to attract fish to eat, avoiding disturbing the fish or causing injury to the fish when the bottom of the barrel pool 1 is cleaned, and the ripples generated on the water surface of the barrel pool 1 will refract sunlight, producing a flashing effect with the floating fish feed, stimulating the feeding instinct of the fish, and fully inducing the fish to swim to the water surface to feed.

[0041] Working principle: When the inner wall of the bottom of the barrel pool 1 is cleaned, the electric discharge valve 28 on the discharge pipe 29 is opened for a period of time, and the time can be controlled automatically. During the period when the electric discharge valve 28 is open, fish feed will fall out of the bottom of the discharge pipe 29 at a uniform speed. During cleaning, the rotating shaft 1 5 will rotate with the gear 2 23. Because there are gears 3 24 meshing with it on both sides of the gear 2 23, the driving shaft 25 on the gear 3 24 can rotate with the turntable 33. Because the boss 32 on the turntable 33 is located in the rectangular groove 31 of the swing plate 27, when the turntable 33 rotates with the boss 32, the swing plate 27 can swing. Because the throwing plate 26 at the bottom of the swing plate 27 is located below the discharge pipe 29, the throwing plate 26 can slap the fish feed that falls from the discharge pipe 29. , thereby slapping the fish feed to a distance, so that the fish feed can be thrown onto the water surface of the barrel pool 1, and when slapping, the fish feed can be broken up to avoid agglomeration, which is convenient for fish to eat. At the same time, during the swinging process of the swinging plate 27, part of the fish feed will collide with the top of the swinging plate 27. Under the action of the impact force, this part of the fish feed can fall on the water surface around the mounting frame 3, so that through cooperation with the throwing plate 26, the fish feed can be fully thrown on the water surface, allowing the fish feed to float on the water surface to attract fish to eat, avoiding disturbing the fish or causing injury to the fish when the bottom of the barrel pool 1 is cleaned, and the ripples generated on the water surface of the barrel pool 1 will refract sunlight, producing a flashing effect with the floating fish feed, stimulating the feeding instinct of the fish, and fully inducing the fish to swim to the water surface to feed.

[0042] Example 3: Reference Figure 8-Figure 9 , a water purification equipment based on land-based barrel pond aquaculture, compared with Example 2, on the basis of Example 2, a sewage trough 38 is opened in the middle position of the bottom of the barrel pond 1, and a through opening connected to the sewage trough 38 is provided at one end thereof, and a sewage cover 34 is sealed and fixedly connected to the outer wall of the through opening, a rotating shaft 40 is provided between the sewage cover 34 and the sewage trough 38, and a spiral auger blade 41 is fixedly connected to the outer wall of the rotating shaft 40, and a protective net 39 is fixedly connected to the inner wall of the sewage trough 38, which can prevent fish in the barrel pond 1 from entering the sewage trough 38, thereby protecting the sewage trough 38.

[0043] As a further solution in the present invention, a driving motor 2 35 for rotating the rotating shaft 40 is provided on the outer wall of the sewage cover 34, and a sewage pipe 37 is provided on the top of the sewage cover 34, and an electric sewage valve 36 is provided on the outer wall of the sewage pipe 37. When cleaning the feces and other garbage attached to the inner wall of the bottom of the barrel pool 1, the driving motor 2 35 is started to rotate the rotating shaft 40. When the rotating shaft 40 rotates, it will rotate the spiral auger blade 41 in the sewage trough 38, so that the sewage trough 38 generates suction, which can pass through the feces and other garbage gathered in the middle of the barrel pool 1. When the inner wall of the bottom of the barrel pool 1 is being cleaned, floating fish feed will be thrown on the water surface of the barrel pool 1, so the fish will float on the water surface, thereby avoiding the suction force that sucks the fish, and the feces and other garbage entering the sewage trough 38 will enter the sewage cover 34 under the drive of the spiral auger blades 41, and the sewage pipe 37 above the sewage cover 34 will be connected to the external filtering and disinfecting equipment. The external filtering and disinfecting equipment used is the existing technology and will not be described in detail here. Then the water after filtration and disinfection is re-transported to the barrel pool 1, thereby completing the work of water purification and recycling.

[0044] Working principle: When cleaning the feces and other garbage attached to the inner wall of the bottom of the barrel pool 1, the driving motor 2 35 is started to rotate the rotating shaft 40. When the rotating shaft 40 rotates, the spiral auger blades 41 in the sewage trough 38 will rotate, so that the sewage trough 38 will generate suction, which can pass through the feces and other garbage gathered in the middle of the barrel pool 1. Because when cleaning the inner wall of the bottom of the barrel pool 1, floating fish feed will be thrown on the water surface of the barrel pool 1, so the fish will float on the water surface, thereby avoiding the suction force that sucks the fish. The feces and other garbage entering the sewage trough 38 will enter the sewage cover 34 under the drive of the spiral auger blades 41, and the sewage pipe 37 above the sewage cover 34 will be connected to the external filtering and disinfecting equipment. The external filtering and disinfecting equipment used is existing technology and will not be described in detail here. Then the filtered and disinfected water will be re-transported to the barrel pool 1, thereby completing the water purification and recycling work.
