Description

Technical Field

[0001] This invention relates to a feeding control device, specifically an adjustable split-type fish feed feeding control device, belonging to the field of offshore platform aquaculture technology. Background Technology

[0002] With the rapid development of my country's marine economy and the continuous improvement of its industrial production level, offshore oil and gas development is becoming increasingly frequent, and more and more offshore oil and gas platforms and other oil and gas production facilities are being used. Since the design life of offshore oil and gas platforms is generally around 20 years, a large number of these platforms are gradually entering the decommissioning stage as they are put into operation. Converting decommissioned offshore oil production facilities into aquaculture bases can save on dismantling costs, reduce offshore operational risks, expand aquaculture space, and reduce the impact on the marine ecological environment, which has significant economic, social, and environmental implications.

[0003] Currently, a method could be adopted that involves building aquaculture areas on oil and gas platforms, extracting seawater from the ocean, storing it within the aquaculture areas on abandoned oil and gas platforms, and establishing a certain supporting system for use. However, this is still in the conceptual stage and requires further improvement.

[0004] In existing offshore platform aquaculture technology, the volume of the aquaculture area on the platform is constant. Large-sized nets are used to completely enclose the fish fry from the outset. However, when the fry are stocked, overly large nets lead to low yields, are prone to breakage, allow fish to escape, and are difficult to catch. Furthermore, when feeding the fry, processed feed is delivered manually or by a feed dispenser to the platform's aquaculture area. If the feed is too compacted, forming large clumps, it is difficult for small fry to swallow. Because the nets are permeable, feed that is not consumed promptly will sink to the bottom of the aquaculture area, resulting in feed waste. Moreover, the caretakers cannot monitor the fry's feeding status, which can lead to malnutrition and hinder their growth. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide an adjustable, separate-type fish feed feeding control device to solve the above-mentioned problems. This addresses the issue that in the prior art, when processed feed is manually or fed by a feed feeder into the aquaculture platform, if the feed is too compacted, forms clumps, and is too large, it is difficult for small fish fry to swallow. Furthermore, because the net is permeable, if the feed is not eaten by the fish fry in time, it will sink to the bottom of the aquaculture area, resulting in feed waste.

[0009] Preferably, the rotating sleeve has multiple clamping plates fixedly connected in a ring array on its outer side, and the threaded sleeve has multiple sliding grooves inside. The multiple clamping plates are respectively adapted to the multiple sliding grooves to limit the threaded sleeve, so that the rotating sleeve drives the threaded sleeve to rotate synchronously. A shrinking sleeve is fixedly connected to one side of the threaded sleeve. The shrinking sleeve is set in an inverted cone shape. The shrinking sleeve is set on the outside of multiple elastic pieces and fits against the multiple elastic pieces. The threaded sleeve drives the shrinking sleeve to move and limits the multiple elastic pieces, causing the multiple elastic pieces to shrink, thereby reducing the discharge port.

[0010] Preferably, a first gear is fixedly connected to the rear side of each of the plurality of rotating sleeves, and a sleeve is fixedly connected to one end of the threaded rod. The sleeve passes through the limiting plate and is rotatably connected to the limiting plate. A second gear is fixedly connected to one end of the sleeve extending into the limiting plate.

The toothed synchronous belt meshes with the plurality of first gears and the second gear respectively, so that when the sleeve rotates, it drives the toothed synchronous belt to move, and the toothed synchronous belt drives the plurality of first gears to rotate, thereby driving the plurality of rotating sleeves to rotate.

[0011] Preferably, the sleeves have integrated limit blocks on both sides, and the threaded rods have limit grooves on both sides. The limit grooves are adapted to the limit blocks, so that when the sleeves rotate, they drive the limit blocks to rotate, and thus drive the threaded rods to rotate with the sleeves. The rear sides of the fixed brackets are fixedly connected to threaded blocks, and the threaded rods pass through the threaded blocks and are threadedly connected to the threaded blocks, so that the threaded rods slide inside the sleeves when they rotate.

[0012] Preferably, the threaded rod is provided with a telescopic conveying pipe inside, the front end of the telescopic conveying pipe passes through the sleeve and is rotatably connected to the sleeve, and the front end of the telescopic conveying pipe is fixedly connected to the connecting pipe, so that the telescopic conveying pipe conveys feed into the connecting pipe.

[0014] Preferably, motors are fixedly connected to both sides of the top of the support plate, and gear reducers are fixedly connected to the top of each of the two motors. The output end of the motor is connected to the input end of the gear reducer to change the transmission direction. Transmission gears are rotatably connected to the output ends of both sides of the gear reducer. Gear rings are rotatably connected to the rear ends of the four sleeves. Multiple gear rings are respectively meshed with multiple transmission gears, so that when the transmission gears rotate, they drive the gear rings to rotate, thereby driving the multiple sleeves to rotate synchronously. Four support blocks are fixedly connected to the top of the support plate, and the four sleeves respectively pass through the four support blocks and are rotatably connected to the support blocks to support the sleeves and improve stability.

[0015] Preferably, the adjustment assembly includes a moving block, a rotating shaft, and a protective net. Multiple moving blocks are fixedly connected to both sides of multiple limiting plates. The rotating shaft is rotatably connected inside the moving block to support it. The protective net is wound around the outside of two rotating shafts at both ends and fixedly connected to them. A through groove is formed inside the side wall of the moving block, through which the protective net slides, limiting its position. A reset wheel is fixedly connected to the outer side of the top of the rotating shaft. A spring is installed inside the reset wheel, with one end fixedly connected to the moving block to limit the rotation of the shaft, allowing it to automatically reset under the action of the reset wheel.

[0016] Preferably, four guide rails are fixedly connected to the top of the bottom net, and four limiting plates are slidably connected to the top of the four guide rails to limit the multiple limiting plates.

The end of the sliding rod away from the support sleeve rod is fixedly connected to the connecting plate, and a spring is sleeved on the outside of the sliding rod. The two ends of the spring are in contact with the support sleeve rod and the connecting plate respectively, which helps to limit the position of the connecting plate and improve the stability of the connecting plate.

[0018] This invention provides an adjustable, split-type fish feed feeding control device, which has the following beneficial effects:

[0019] 1. This adjustable, split-type fish feed control device allows for the release of fish fry into the aquaculture area. The small fry are raised within this area, and feed is directly introduced into the aquaculture area via a feed hopper and a feed box. Feed from the feed box falls into the aquaculture area through the outlet to feed the fry. Once the fry have grown slightly, they are released between the aquaculture area and the protective netting. The feed box then transfers the feed to a telescopic feed pipe, which in turn delivers it to a connecting pipe. From there, the feed is transferred to multiple rotating sleeves, from which it is sprayed out. The feed is then sprayed out from multiple elastic plates, which are in a compressed state. This process divides and compresses the feed, resulting in small, easily digestible strips that are convenient for the fry to eat. This prevents feed from clumping together and becoming too large, which would prevent the fry from swallowing it immediately and sinking away from the bottom netting, causing waste and nutritional deficiencies in the fry.

[0020] 2. This adjustable, split-type fish feed control device allows the fry to be released between the breeding area and the protective net after they have grown slightly. The feed box then transfers the feed to the telescopic feed pipe, which in turn delivers the feed to the connecting pipe. From there, the feed is transferred to multiple rotating sleeves, from which it is sprayed out. The feed is then sprayed out from multiple elastic plates, which are in a compressed state. This allows the elastic plates to divide and compress the feed, resulting in small strips that are easy for the fry to swallow. This prevents the feed from clumping together and becoming too large, which would prevent the fry from swallowing it immediately. The feed would also prevent it from slowly sinking and detaching from the bottom net, causing waste and potentially leading to malnutrition in the fry.

[0021] 3. This adjustable, split-type fish feed control device, when the fish fry grow, starts the motor, causing the motor to drive two transmission gears through a gear reducer to grow, which in turn drives the gear ring to grow, thus rotating the sleeve. When the sleeve rotates, the limiting block limits the limiting groove, smoothly driving the threaded rod to rotate synchronously. Because the threaded rod is threadedly connected to the threaded block, when the threaded rod rotates, it moves horizontally, allowing it to slide inside the sleeve. The threaded rod also drives the sleeve to move, causing the sleeve to move the limiting plate, thus driving multiple... The limiting plate expands outward, and the limiting plate moves along with the moving block. As the moving block expands outward, the protective net opens outward. At the same time, the protective net pulls the rotating shaft to rotate, causing the rotating shaft to drive the reset wheel to rotate, so that the protective net unfolds to fit the position of the limiting plate. When the protective net opens, it drives the connecting plate to move. At the same time, the moving block drives the telescopic plate to slide from the inside of the connecting plate to both sides to support the protective net. When the moving block moves, it drives the sliding rod to move, and the spring supports the support sleeve rod and the moving block, improving its stability and making it more suitable for fish with larger body sizes.

[0022] 4. This adjustable, split-type fish feed feeding control device, when the threaded rod rotates, drives the sleeve to rotate, causing the sleeve to drive the second gear to rotate, which in turn drives the toothed synchronous belt to move, and drives multiple first gears to rotate. When the first gears rotate, they drive the rotating sleeve to rotate, causing the rotating sleeve to drive the clamping plate to rotate, so that the clamping plate limits the threaded sleeve and drives the threaded sleeve to rotate synchronously. Because the threaded sleeve is threadedly connected to the side wall of the limiting plate, the threaded sleeve moves when it rotates, thereby driving the shrinking sleeve to move, causing the shrinking sleeve to disengage from multiple elastic plates, and causing the multiple elastic plates to open outward under their own elastic force, so that the feed is sprayed out from inside the multiple elastic plates when it is discharged, making the feed into a thick and long strip shape, which is convenient for feeding large fish.

[0041] Multiple clamping plates 12 are fixedly connected in a ring array on the outer side of the rotating sleeve 11. Multiple sliding grooves are opened inside the threaded sleeve 14. The multiple clamping plates 12 are respectively adapted to the multiple sliding grooves to limit the threaded sleeve 14, so that the rotating sleeve 11 drives the threaded sleeve 14 to rotate synchronously. A shrinking sleeve 15 is fixedly connected to one side of the threaded sleeve 14. The shrinking sleeve 15 is set in an inverted cone shape. The shrinking sleeve 15 is set on the outside of multiple elastic pieces 13 and fits against the multiple elastic pieces 13, so that the threaded sleeve 14 drives the shrinking sleeve 15 to move and limits the multiple elastic pieces 13, so that the multiple elastic pieces 13 shrink, thereby reducing the discharge port.

[0042] Multiple rotating sleeves 11 are fixedly connected to the rear side of a first gear 16. A sleeve 10 is fixedly connected to one end of a threaded rod 7. The sleeve 10 passes through a limiting plate 8 and is rotatably connected to the limiting plate 8. A second gear 17 is fixedly connected to one end of the sleeve 10 extending into the limiting plate 8. A toothed synchronous belt 18 is sleeved on the outside of the second gear 17 and multiple first gears 16. The toothed synchronous belt 18 meshes with multiple first gears 16 and the second gear 17 respectively, so that when the sleeve 10 rotates, it drives the toothed synchronous belt 18 to move, and the toothed synchronous belt 18 drives multiple first gears 16 to rotate, thereby driving multiple rotating sleeves 11 to rotate.

[0043] Multiple sleeves 6 have integrated limiting blocks 20 on both sides inside, and multiple threaded rods 7 have limiting grooves 19 on both sides. The limiting grooves 19 are adapted to the limiting blocks 20, so that when the sleeves 6 rotate, they drive the limiting blocks 20 to rotate, and thus drive the threaded rods 7 to rotate with the sleeves 6. Multiple fixing brackets 5 are fixedly connected to the rear side of multiple threaded blocks 31. Multiple threaded rods 7 pass through multiple threaded blocks 31 and are threadedly connected to multiple threaded blocks 31, so that the threaded rods 7 slide inside the sleeves 6 when rotating.

[0044] The threaded rod 7 is equipped with a telescopic feed pipe 32. The front end of the telescopic feed pipe 32 passes through the sleeve 10 and is rotatably connected to the sleeve 10. The front end of the telescopic feed pipe 32 is fixedly connected to the connecting pipe 9, so that the telescopic feed pipe 32 transmits feed into the connecting pipe 9. The feeding component includes a feed box 38 and a feed hopper 39. The bottom of the feed box 38 extends into the breeding area 1 and is provided with a discharge port. The feed box 38 is fixedly connected to the top of the support plate 4. The feed hopper 39 is fixedly connected to the top of the feed box 38. The rear end of the telescopic feed pipe 32 passes through the sleeve 6 and is rotatably connected to the sleeve 6. The rear end of the telescopic feed pipe 32 is fixedly connected to the feed box 38, so that the feed box 38 transmits feed through the telescopic feed pipe 32.

[0045] Motors 34 are fixedly connected to both sides of the top of the support plate 4. Gear reducers 35 are fixedly connected to the top of each of the two motors 34. The output end of the motor 34 is connected to the input end of the gear reducer 35 to change the transmission direction. Transmission gears 36 are rotatably connected to the output ends of both sides of the gear reducer 35. Gear rings 37 are rotatably connected to the rear ends of the four sleeves 6. Multiple gear rings 37 are meshed with multiple transmission gears 36 respectively, so that when the transmission gears 36 rotate, they drive the gear rings 37 to rotate, thereby driving multiple sleeves 6 to rotate synchronously. Four support blocks 33 are fixedly connected to the top of the support plate 4. The four sleeves 6 pass through the four support blocks 33 respectively and are rotatably connected to the support blocks 33 to support the sleeves 6 and improve stability.

[0046] The adjustment assembly includes a moving block 21, a rotating shaft 22, and a protective net 23. Multiple moving blocks 21 are fixedly connected to both sides of multiple limiting plates 8. The rotating shaft 22 is rotatably connected inside the moving block 21 to support the moving block 21. The two ends of the protective net 23 are respectively wound around the outside of the two rotating shafts 22 and fixedly connected to the two rotating shafts 22. A through groove 25 is opened inside the side wall of the moving block 21. The protective net 23 passes through the through groove 25 and is slidably connected to the through groove 25 to limit the position of the protective net 23. A reset wheel 24 is fixedly connected to the outer side of the top of the rotating shaft 22. A spring is provided inside the reset wheel 24. One end of the spring is fixedly connected to the moving block 21 to limit the position of the rotating shaft 22, so that the rotating shaft 22 can automatically reset under the drive of the reset wheel 24.

[0047] Four guide rails 40 are fixedly connected to the top of the bottom net 2. Four limiting plates 8 are slidably connected to the top of the four guide rails 40 to limit the multiple limiting plates 8. A connecting plate 26 is fixedly connected to the middle of the top of the protective net 23. Telescopic plates 27 are slidably connected to both sides inside the connecting plate 26. One end of each of the two telescopic plates 27 is fixedly connected to two moving blocks 21 to support the protective net 23, improve the strength of the protective net 23, and prevent loosening. Support sleeve rods 28 are fixedly connected to both sides inside the fixed frame 5. A sliding rod 29 is slidably connected inside the support sleeve rod 28. The end of the sliding rod 29 away from the support sleeve rod 28 is fixedly connected to the connecting plate 26. A spring 30 is sleeved on the outside of the sliding rod 29. The two ends of the spring 30 are in contact with the support sleeve rod 28 and the connecting plate 26, which helps to limit the connecting plate 26 and improve the stability of the connecting plate 26.

[0048] Specifically, the bottom net 2 is set inside the aquaculture area of ​​the offshore aquaculture platform, and the device is submerged in the seawater of the aquaculture area, with only the support frame 3 and the components installed on the support frame 3 above the water surface.

[0049] Fish fry are released into the breeding area 1 to raise the small fish fry. Feed is directly fed into the breeding area 1 through the feed hopper 39 and the feed box 38, so that the feed in the feed box 38 falls into the breeding area 1 from the discharge port to feed the fish fry.

[0050] Once the fish fry have grown a little, they are released between the breeding area 1 and the protective net 23. The feed box 38 transfers the feed to the telescopic feed pipe 32, which then delivers the feed to the connecting pipe 9. From the connecting pipe 9, the feed is transferred to multiple rotating sleeves 11, where it is sprayed out and onto multiple elastic plates 13. The elastic plates 13 are in a compressed state, which divides and compresses the feed, making it into small strips that are easy for the fish fry to eat. This prevents the feed from clumping together and becoming too large, which would prevent the fish fry from swallowing it immediately. The feed would also prevent it from slowly sinking and detaching from the bottom net 2, causing waste and potentially leading to malnutrition in the fish fry.

[0051] As the fish fry grow, the motor 34 is started, which drives two transmission gears 36 through the gear reducer 35 to grow. These gears then drive the gear ring 37 to grow, causing the sleeve 6 to rotate. When the sleeve 6 rotates, the limiting block 20 limits the limiting groove 19, smoothly driving the threaded rod 7 to rotate synchronously. Because the threaded rod 7 is threadedly connected to the threaded block 31, it moves horizontally during rotation, sliding inside the sleeve 6. The threaded rod 7 also drives the sleeve 10 to move, causing the sleeve 10 to move the limiting plate 8, expanding the multiple limiting plates 8 outwards. The movable block 21 is moved, causing the protective net 23 to open outward as it expands. At the same time, the protective net 23 pulls the rotating shaft 22 to rotate, causing the rotating shaft 22 to drive the reset wheel 24 to rotate, thus unfolding the protective net 23 to fit the position of the limiting plate 8. When the protective net 23 opens, it drives the connecting plate 26 to move. Simultaneously, the movable block 21 drives the telescopic plate 27 to slide from the inside of the connecting plate 26 to both sides to support the protective net 23. When the movable block 21 moves, it drives the sliding rod 29 to move, and the spring 30 supports the supporting sleeve rod 28 and the movable block 21, improving its stability and making it suitable for larger fish.

[0052] When the threaded rod 7 rotates, it drives the sleeve 10 to rotate, which in turn drives the second gear 17 to rotate. This causes the second gear 17 to move the toothed synchronous belt 18 and drive multiple first gears 16 to rotate. When the first gears 16 rotate, they drive the rotating sleeve 11 to rotate, which in turn drives the clamping plate 12 to rotate. The clamping plate 12 then limits the threaded sleeve 14, causing the threaded sleeve 14 to rotate synchronously. Because the threaded sleeve 14 is threadedly connected to the side wall of the limiting plate 8, it moves during rotation, which in turn moves the contraction sleeve 15. This causes the contraction sleeve 15 to disengage from multiple elastic plates 13, and the multiple elastic plates 13 to open outward under their own elasticity. This allows the feed to be sprayed out from inside the multiple elastic plates 13 during discharge, making the feed long and thick, which is convenient for feeding large fish.
