Description

Technical Field

[0001] This utility model relates to the field of aquaculture pond cleaning technology, and in particular to an aquaculture pond cleaning device. Background Technology

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It generally includes the entire process of raising aquatic products from seedlings under artificial feeding and management. In a broader sense, it can also include the enhancement of aquatic resources. Aquaculture can be carried out in various ways, such as extensive farming, intensive farming, and high-density intensive farming. Extensive farming involves releasing seedlings into small and medium-sized natural water bodies and raising aquatic products entirely by relying on natural feed, such as fish farming in lakes and reservoirs and shellfish farming in shallow seas. Intensive farming involves raising aquatic products in smaller water bodies by feeding and fertilizing, such as fish farming in ponds, cages, and enclosures. High-density intensive farming uses methods such as flowing water, temperature control, oxygenation, and feeding high-quality feed to carry out high-density farming in small water bodies, thereby achieving high yields.

[0003] In aquaculture ponds used for extended periods, algae and biofilms adhere to the pond walls and bottom. The ability to clean hardened sludge and clumps of debris becomes significantly reduced. High-pressure impact or vibration alone is insufficient to thoroughly remove firmly attached sludge, leaving cleaning dead zones that require manual labor or other less efficient methods. This results in residual contaminants on the pond bottom and walls, which, over time, negatively impact the aquaculture environment. Uneven cleaning results may also reduce the equipment's effectiveness for aquatic life. Aquatic organisms in aquaculture ponds require sufficient dissolved oxygen for normal respiration and metabolism. Without oxygen supply systems, dissolved oxygen levels in the pond water may be insufficient, especially under high-density farming or high-temperature conditions. This can easily lead to water quality deterioration, causing fish and shrimp to surface for air, slow growth, and even mass mortality. This increases equipment costs and maintenance difficulty, potentially impacting the efficiency and cost of aquaculture management. Utility Model Content

[0004] The main purpose of this utility model is to provide an aquaculture pond cleaning device that can effectively solve the problems of residual pollution on the pond bottom and walls, which can affect the aquaculture environment over a long period of time, result in uneven cleaning effects, reduce the impact of the equipment on aquatic organisms, and cause fish and shrimp to float to the surface, grow slowly, or even die in large numbers, thereby increasing equipment costs and maintenance difficulties, and potentially affecting the efficiency and cost of aquaculture management.

[0007] Furthermore, each of the two connecting rods has a connecting block fixedly connected to its other end. Both connecting blocks are located at the top of the pool body. A second slider is fixedly connected inside each of the two connecting blocks. The outer sides of the two second sliders are located inside the second guide groove. A second scraper is fixedly connected inside each of the two connecting blocks. The two second scrapers are correspondingly arranged with the inner wall of the pool body.

[0008] Furthermore, a control panel is fixedly connected to the rear side wall of the pool, a waste discharge baffle is fixedly connected to the bottom of the pool, a storage box is provided on the outside of the waste discharge baffle, the inner side wall of the storage box is fixedly connected to the bottom outside of the pool, and a guide plate is fixedly connected inside the storage box.

[0009] Furthermore, a support plate is fixedly connected to the rear side wall of the support base, a pump is provided on the top of the support plate, a connecting pipe is fixedly connected to the input end of the pump, the top end of the connecting pipe is connected through to the rear side wall of the storage box, and a waste discharge pipe is fixedly connected to the output end of the connecting pipe.

[0010] Furthermore, the connecting ring has adapter pipes running through its front and rear sides, the bottom ends of the two adapter pipes are connected to conveying pipes, the right ends of the two conveying pipes are connected to air inlet pipes, and the right ends of the two air inlet pipes are connected through the right side wall of the support base.

[0011] Furthermore, the top ends of both of the two connecting pipes are connected to air outlet pipes, the outer walls of both air outlet pipes are connected to air outlet nozzles, and the interiors of both air outlet nozzles are fixedly connected to diffuser plates.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model, through its connecting column, motor, rotating rod, first guide rail groove, first scraper, second slider, and second scraper, solves the problem of residual pollution on the bottom and walls of the pool, which, over time, affects the aquaculture environment, results in uneven cleaning, and may reduce the equipment's impact on aquatic organisms. The first scraper, in circular motion against the surface of the conical disc, pushes the dirt from the bottom of the pool towards the edge. Simultaneously, the second fixing ring at the top of the connecting column drives the connecting block to rotate via the connecting rod, and the second slider slides along the second guide rail groove at the top of the support base, causing the second scraper to closely adhere to the inner wall of the pool and perform circular scraping to remove attached dirt.

[0015] 2. By incorporating a transfer pipe, air inlet pipe, air outlet pipe, diffuser plate, and second air outlet, the system addresses issues that cause fish and shrimp to surface for air, slow growth, and even mass mortality, increasing equipment costs and maintenance difficulty, and potentially impacting the efficiency and cost of aquaculture management. The first air outlet on both sides of the top of the connecting column allows some air bubbles to directly enter the upper water layer of the pond, increasing dissolved oxygen levels and alleviating oxygen deficiency caused by water agitation during cleaning operations. The second air outlet on both sides of the second fixing ring, in conjunction with its rotation, allows air bubbles to diffuse synchronously with the second scraper to the inner wall of the pond, effectively aiding normal respiration and metabolism in aquatic organisms, reducing the risk of oxygen deficiency, improving feed conversion rate, reducing disease incidence, and extending the equipment's lifespan.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] like Figure 1 - Figure 11 As shown: Aquaculture pond cleaning device includes a support base 1, with a pond body 2 fixedly connected to the top of the support base 1. The support base 1 provides bottom support for the pond body 2 and also protects the motor 6 from water contact through its interior. A conical disc 3 is fixedly connected to the inner bottom wall of the pond body 2. The conical disc 3 prevents impurities in the water from remaining in the middle area of ​​the pond body 2 and allows them to flow towards the edges.

[0032] A connecting column 4 runs through the interior of the conical disk 3. A top ring 5 is fixedly connected to the top of the connecting column 4. The connecting column 4 supports the devices at both ends, achieving the effect of a column. A motor 6 is installed inside the support base 1. A rotating rod 7 is fixedly connected to the output end of the motor 6. The top of the rotating rod 7 is fixedly connected to the bottom wall of the top ring 5. A connecting ring 8 is provided on the outer side of the bottom end of the rotating rod 7. The bottom end of the connecting column 4 is rotatably connected to the outer side of the connecting ring 8. A first fixing ring 9 is fixedly connected to the outer side of the bottom end of the connecting column 4. First guide rail grooves 10 are provided on both the front and rear sides of the first fixing ring 9. First sliders 11 are slidably connected inside the two first guide rail grooves 10. Mounting blocks 12 are fixedly connected to the top of the two first sliders 11. Each mounting block 12 is set in one first guide rail groove 10. At the top, a second fixing ring 14 is fixedly connected to the outer side of the top of the connecting column 4. When it is necessary to clean the inside of the pool body 2, the motor 6 is started. The rotating rod 7 on the output end of the motor 6 is connected to the bottom wall of the top ring 5 and is set inside the connecting column 4. Thus, when the rotating rod 7 rotates, it drives the connecting column 4 to rotate inside the pool body 2 through the connection between the rotating rod 7 and the bottom wall of the top ring 5. The first fixing ring 9 on the outer side of the bottom of the connecting column 4 rotates synchronously with the connecting column 4. The first slider 11 in the first guide groove 10 on its front and rear sides drives the first scraper 13 to rotate. Since the bottom of the first scraper 13 is in contact with the top of the conical disk 3, under the rotation drive of the connecting column 4, the first scraper 13 will make a circular motion along the inclined surface of the conical disk 3, pushing the silt, uneaten food and other dirt at the bottom of the pool body 2 to the edge of the conical disk 3.

[0033] When the first scraper 13 needs to be disassembled, the mounting block 12 is pulled, causing the mounting block 12 to slide the first slider 11 out of the first guide rail groove 10, thereby disassembling and replacing the first scraper 13. After replacement, the first slider 11 is reinserted into the first guide rail groove 10, and the mounting block 12 on the top wall will seal the top of the first guide rail groove 10 to prevent impurities from entering the interior.

[0034] Two first sliders 11 are fixedly connected to the outer walls of their respective first scrapers 13. The bottom of the first scraper 13 corresponds to the top of the conical disc 3. Two connecting rods 15 are fixedly connected to the left and right sides of the second fixing ring 14. The two connecting rods 15 are connected by the second fixing ring 14 on the top of the connecting column 4. When the connecting column 4 is driven, the second fixing ring 14 on its outer side and the connecting rods 15 will rotate synchronously. A second guide groove 18 is provided on the outer side of the top of the pool body 2. The other end of each of the two connecting rods 15 is fixedly connected to a connecting block 16. Both connecting blocks 16 are located on the top of the pool body 2. A second slider 17 is fixedly connected inside each of the two connecting blocks 16. The outer sides of the two second sliders 17 are located inside the second guide groove 18. A second scraper 19 is fixedly connected inside each of the two connecting blocks 16. The two second scrapers 19 correspond to the inner walls of the pool body 2. When the second fixing ring 14 on the outer side of the top of the connecting column 4 rotates with the connecting column 4, the connecting rods 15 on its left and right sides drive the connecting blocks 16 to rotate synchronously. The connecting block 16 is embedded in the second guide groove 18 at the top of the pool body 2 via the internal second slider 17, forming a stable circular motion trajectory. At this time, the second scraper 19 inside the connecting block 16 is in corresponding contact with the inner wall of the pool body 2, and will perform a circular scraping motion along the inner wall of the pool body 2 as the connecting block 16 rotates, removing algae, biofilm and residual dirt attached to the pool wall.

[0035] A control panel 20 is fixedly connected to the rear wall of the pool body 2, and a baffle 21 is fixedly connected to the bottom of the pool body 2. The baffle 21 prevents fish and shrimp from entering the storage tank 22, and the conical disc 3 guides impurities through the baffle 21 into the storage tank 22. A storage tank 22 is located outside the baffle 21. The storage tank 22 is used for temporary storage of impurities, and its angle is tilted backward to allow impurities and water entering the storage tank 22 to flow backward.

[0036] The inner wall of the storage tank 22 is fixedly connected to the bottom outer side of the pool body 2. A guide plate 23 is fixedly connected inside the storage tank 22. A support plate 24 is fixedly connected to the rear wall of the support base 1. A pump 25 is installed on the top of the support plate 24. A connecting pipe 26 is fixedly connected to the input end of the pump 25. The top end of the connecting pipe 26 is connected through the rear wall of the storage tank 22. A discharge pipe 27 is fixedly connected to the output end of the connecting pipe 26. Waste pushed to the edge of the conical disc 3 by the first scraper 13 slides towards the bottom of the pool body 2 due to the guiding effect of the conical disc 3, and enters the interior of the storage tank 22 through the discharge baffle 21 at the bottom of the pool body 2. The guide plate 23 inside the storage tank 22 guides the waste to accumulate at the bottom of the storage tank 22, preventing accumulation and blockage of the inlet. When the amount of sludge accumulated in the storage tank 22 reaches a certain level, the pump 25 on the support plate 24 is activated, and the sludge in the storage tank 22 is extracted through the connecting pipe 26 and then transported to the external treatment equipment through the discharge pipe 27, thus completing the final transfer of the sludge.

[0037] The connecting ring 8 has two connecting pipes 28 that are connected through the front and rear sides. The bottom ends of the two connecting pipes 28 are connected to the conveying pipes 29. The right ends of the two conveying pipes 29 are connected to the air inlet pipes 30. The right ends of the two air inlet pipes 30 are connected through the right side wall of the support base 1. The top ends of the two connecting pipes 28 are connected to the air outlet pipes 31. The outer side walls of the two air outlet pipes 31 are connected to the air outlet heads 32. The interior of the two air outlet heads 32 is fixedly connected to the diffuser plate 33. The top end of the connecting column 4 has a first air outlet hole 34 on both the front and rear sides. The front and rear side walls of the second fixing ring 14 have a second air outlet hole 35. The interior of the second air outlet hole 35 and the first air outlet hole 34 are correspondingly arranged with the air outlet head 32. The first two air inlet pipes 30 are connected to external air compressors, air pumps, etc., so that the gas is delivered to the interior of the air outlet pipe 31 through the air inlet pipe 30, the delivery pipe 29 on the left end and the transfer pipe 28. When in use, the gas is sprayed out through the air outlet head 32 at the top of the air outlet pipe 31 and dispersed into fine bubbles through the diffuser plate 33 inside the air outlet head 32, so that the bubbles directly enter the upper water of the pool body 2 and increase the dissolved oxygen content of the water.

[0038] And through the second air outlet 35 on both sides of the second fixed ring 14, in conjunction with the rotation of the second fixed ring 14, the air bubbles are diffused synchronously with the second scraper 19 to the inner wall area of ​​the pool body 2. On the one hand, the air bubble disturbance enhances the stripping effect of the second scraper 19 on the pool wall dirt, and on the other hand, it inhibits the growth of anaerobic bacteria near the pool wall.

[0039] In addition, the second fixing ring 14 rotates with the rotation of the connecting column 4, so that the bubbles can be evenly distributed around the inside of the pool body 2 as the second fixing ring 14 moves.

[0040] It should be noted that this utility model is a cleaning device for aquaculture ponds. First, the motor 6 and control panel 20 are connected to an external power source to supply power to the device.

[0041] The equipment is started by the control panel 20. The motor 6 inside the support base 1 outputs power, which drives the top ring 5 and the connecting column 4 to rotate synchronously through the rotating rod 7. Its core cleaning action is the same as the original structure: when the first fixing ring 9 at the bottom of the connecting column 4 rotates, the first slider 11 slides outward along the first guide groove 10 under the action of centrifugal force, so that the first scraper 13 is in contact with the surface of the conical disk 3 to make a circular motion, pushing the dirt at the bottom of the pool to the edge; at the same time, the second fixing ring 14 at the top of the connecting column 4 drives the connecting block 16 to rotate through the connecting rod 15, and the second slider 17 slides along the second guide groove 18 at the top of the support base 1, so that the second scraper 19 is in close contact with the inner wall of the pool body 2 to make a circular scraping to remove the attached dirt.

[0042] The sludge pushed to the edge of the conical disc 3 by the first scraper 13 slides towards the bottom of the tank 2 due to the guiding effect of the conical structure, and enters the storage tank 22 through the waste discharge baffle 21 at the bottom of the tank 2. The guide plate 23 inside the storage tank 22 is designed with an inclination to guide the sludge to gather at the bottom of the tank and avoid accumulation and blockage of the inlet. When the sludge in the storage tank 22 accumulates to a certain amount, the pump 25 on the support plate 24 is started, and the sludge in the storage tank 22 is extracted through the connecting pipe 26 and then transported to the external treatment equipment through the waste discharge pipe 27, completing the final transfer of sludge.

[0043] Gas is input through the inlet pipe 30 that runs through the right side wall of the support base 1. The gas is then split into two delivery pipes 29 via the inlet pipe 30, and then guided into the transfer pipe 28 inside the connecting ring 8 via the delivery pipe 29. Since the connecting ring 8, rotating rod 7, and connecting column 4 maintain relative rotation but are in sealed communication, the gas can be stably delivered upward through the transfer pipe 28 to the outlet pipe 31, and finally ejected from the outlet nozzle 32.

[0044] The gas ejected from the air nozzle 32 is dispersed into fine bubbles by the internal diffuser plate 33, and acts on the aquaculture pond through two paths: the first air outlet 34 on the front and rear sides of the top of the connecting column 4 allows some bubbles to directly enter the upper layer of water in the pond 2, increasing the dissolved oxygen content of the water and alleviating the oxygen deficiency problem caused by water agitation during cleaning operations; the second air outlet 35 on the front and rear sides of the second fixing ring 14, in conjunction with the rotational movement of the second fixing ring 14, allows the bubbles to diffuse synchronously with the second scraper 19 to the inner wall area of ​​the pond 2. On the one hand, the bubble disturbance enhances the removal effect of the second scraper 19 on the pond wall dirt, and on the other hand, it inhibits the growth of anaerobic bacteria near the pond wall.
