Description

Technical Field

[0001] This utility model designs a factory-style aquaculture equipment, which is a shrimp shell collection device outside the aquaculture pond that collects shrimp shells through a circulating water pipe. Background Technology

[0002] In aquaculture, maintaining clean water quality is not only crucial for the healthy growth of shrimp but also directly impacts the economic benefits of farming. Shrimp molt multiple times during their growth process, in addition to excreting waste. Timely and effective collection and treatment of waste and shells can reduce the risk of disease transmission, decrease shrimp mortality, and ultimately increase yields. Furthermore, timely shell collection reduces pond blockage, improves water quality, lowers wastewater treatment costs, and generates direct economic benefits. Shrimp shells, as a byproduct, have wide commercial uses, such as being used as animal feed or for extracting valuable chemical raw materials like chitin. Therefore, efficient shell collection not only protects the aquaculture environment but also creates additional income for farmers.

[0003] Currently available shrimp shell collection devices are typically placed inside the aquaculture pond, a design with several significant drawbacks. First, the pipes and shrimp shell collection baskets occupy space within the pond, disrupting water flow and reducing the efficiency of vortex-like flow. This impacts the effective collection of shrimp shells and waste to the central collection point. To achieve the desired swirling flow speed, additional water-pushing devices are necessary, increasing investment costs and energy consumption, thus affecting aquaculture costs and economic benefits. Second, the presence of the collection baskets and pipes within the pond makes manual cleaning inconvenient. It also increases the risk of workers tripping over the pipes, complicating maintenance and creating safety hazards, while interfering with shrimp harvesting nets. Third, the dual-pipe design significantly increases construction and maintenance costs, requiring additional materials and equipment to install and operate two separate systems, placing a greater economic burden on the farm. Finally, some shrimp shell collection devices may have water flowing through the collection pipes for only a short time. Long-term stagnation of the water flow can cause shrimp shells, shrimp feces, and other waste to decompose and deteriorate in the shrimp shell collection pipes. The resulting harmful pollutants can cause shrimp to become ill and die, leading to aquaculture failure. Utility Model Content

[0004] The purpose of this application is to provide a shrimp shell collection device for aquaculture ponds that collects shrimp shells through a circulating water pipe in order to solve the problems mentioned above.

[0005] The technical solution adopted in this application is as follows: a shrimp shell collection device for aquaculture ponds that collects shrimp shells through a circulating water pipe, including a bottom drain outlet of the shrimp pond, a double-cone baffle is provided at the upper end of the bottom drain outlet of the shrimp pond, a plurality of top drainage holes are provided on the outer surface of the double-cone baffle, a bottom drainage hole is provided at the lower end of the double-cone baffle, a rope fixing hole is provided at one end of the double-cone baffle relative to the bottom drainage hole, and a lifting rope is provided at one end of the rope fixing hole relative to the double-cone baffle.

[0006] By adopting the above technical solution, the pond-side water level tank and the shrimp shell baffle are connected by a pipe. The shrimp shell baffle has multiple small holes for shrimp feces and fine particulate matter to pass through only. When the shrimp shell baffle is pulled up with a rope to form a gap of a certain size, the shrimp shells will flow through the gap to the shrimp shell collection basket. Otherwise, only shrimp feces, fine particulate matter, and water can flow through the filter holes to the shrimp shell collection basket. The pond-side water level tank is equipped with a shrimp shell collection basket for collecting shrimp shells. The shrimp shell collection basket has multiple drainage holes for water flow and shrimp feces and other debris to pass through only, thus separating the debris from the shrimp shells. This device uses the water level difference to simultaneously achieve the return flow of shrimp feces and other wastewater and the collection of shrimp shells through a circulation pipe, thereby avoiding the situation of having a separate shrimp shell collection pipe and shrimp shell collection basket in the shrimp pond, and preventing the deterioration of debris in the independent shrimp shell collection pipe due to prolonged stagnant water. The pond-side water level tank is also equipped with a water level control pipe to maintain the stability of the water level in the aquaculture pond. The entire pipeline is very simple and is buried below the bottom of the shrimp pond, which further optimizes the use of space in the pond, reduces interference with water flow and aquaculture operations, lowers aquaculture risks, and significantly reduces construction costs and construction difficulty.

[0007] In a preferred embodiment, the outer surface of the bottom drainage hole is provided with counterweight concrete.

[0008] By adopting the above technical solution, counterweight concrete may be placed on components such as shrimp shell and live shrimp baffles. By increasing the weight, the baffles can stably cover the bottom outlet of the shrimp pond when not in operation, preventing shrimp shells or live shrimp from flowing out prematurely before the collection time.

[0009] In a preferred embodiment, an aquaculture pond is provided on the outer surface of the bottom outlet of the shrimp pond, and aquaculture pond walls are provided around the aquaculture pond.

[0010] By adopting the above technical solution, the aquaculture pond serves as the primary space for shrimp growth, providing a living environment for them. However, it also generates shrimp feces, shells, and other waste, with a central bottom drain facilitating waste collection. The pond walls form the boundary of the aquaculture pond, effectively enclosing the water body.

[0011] In a preferred embodiment, a circulating water pipe is provided on one side of the bottom drainage hole.

[0012] By adopting the above technical solution, the circulating water pipe is a single shared pipe that is responsible for transporting circulating water containing shrimp feces and other fine waste, and can also carry shrimp shells to the water level tank on the side of the pond when collecting shrimp shells, thus achieving a dual function.

[0013] In a preferred embodiment, a pool-side water level tank is fixedly connected to one end of the aquaculture pool wall.

[0014] By adopting the above technical solution, the water level tank on the side of the pond is connected to the circulating water pipe, and a shrimp shell collection basket is placed inside to temporarily store the shrimp shells. At the same time, the water level control pipe maintains the stability of the water level in the aquaculture pond. It is an important component for the separation of waste and the transfer of water flow.

[0015] In a preferred embodiment, a shrimp shell collection basket is provided at one end of the circulating water pipe relative to the bottom drain hole.

[0016] By adopting the above technical solution, the shrimp shell collection basket is located in the water level tank on the side of the pond. Its filter holes only allow water flow and small debris such as shrimp feces to pass through, which can effectively intercept shrimp shells and facilitate manual removal and dumping, thus realizing the centralized collection and treatment of shrimp shells.

[0017] In a preferred embodiment, a microfiltration machine's circulating water return pipe is provided on one end of the shrimp shell collection basket adjacent to the circulating water pipe.

[0018] By adopting the above technical solution, the circulating water return pipe of the microfilter connects the water level tank on the side of the pool to the microfilter, and transports the water containing shrimp feces and other pollutants after being filtered by the shrimp shell collection basket to the microfilter for deep purification, thus ensuring the quality of the circulating water.

[0019] In a preferred embodiment, a water level control pipe switch is provided at one end of the circulating water pipe, and a water level control pipe is provided at one end of the circulating water pipe relative to the water level control pipe switch.

[0020] By adopting the above technical solution, the water level control pipe is installed inside one side of the circulating water pipeline. It precisely maintains the stability of the water level in the aquaculture pond by regulating the water flow rate, providing a suitable aquatic environment for shrimp growth and ensuring smooth aquaculture operations. The water level control pipe switch can control the on / off state of the pipe or the water flow rate, assisted by the water level control pipe in flexibly adjusting the water level in the aquaculture pond to meet the different water level requirements of shrimp at different growth stages.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: In this application, the pond-side water level tank is connected to the shrimp shell baffle via a pipe. The shrimp shell baffle has multiple small holes for shrimp feces and fine particulate matter to pass through only. When the shrimp shell baffle is pulled up with a rope to create a gap of a certain size, shrimp shells will flow through the gap to the shrimp shell collection basket. Otherwise, only shrimp feces, fine particulate matter, and water can flow through the filter holes to the shrimp shell collection basket. The pond-side water level tank is equipped with a shrimp shell collection basket for collecting shrimp shells. The shrimp shell collection basket has multiple drainage holes for water flow and shrimp feces to pass through only, achieving separation of waste and shrimp shells. This device, through the effect of water level difference, uses a circulation pipe to simultaneously achieve the return flow of wastewater such as shrimp feces and the collection of shrimp shells, thereby avoiding the existence of shrimp shell collection pipes and shrimp shell collection baskets within the shrimp pond, and preventing the waste in the independent shrimp shell collection pipe from deteriorating due to prolonged stagnant water. The pond-side water level tank is also equipped with a water level control pipe to maintain the stability of the water level in the aquaculture pond. The entire pipeline is very simple and is buried below the bottom of the shrimp pond, which further optimizes the use of space in the pond, reduces interference with water flow and aquaculture operations, lowers aquaculture risks, and significantly reduces construction costs and construction difficulty.

[0022] Firstly, this invention employs a single-pipe design to function as both a circulating water pipe and a shrimp shell collection pipe. This avoids the problem of water flow obstruction caused by placing traditional shrimp shell collection pipes and baskets inside the shrimp pond. This allows for smoother water flow rotation within the pond, improving the collection efficiency of shrimp shells and feces towards the center, thus reducing the facility costs and energy consumption associated with adding water flow control devices to address obstructions. Secondly, the single-pipe design eliminates unnecessary pipes within the shrimp pond, providing more spacious living space for the shrimp and reducing the risk of injury from collisions with pipes. It also makes the pond more aesthetically pleasing. Furthermore, installing a single pipe at the bottom of the pond avoids interference with manual operation and cleaning, reducing the risk of tripping during maintenance and minimizing pipe interference with shrimp nets during harvesting. Placing the shrimp shell collection basket outside the pond also facilitates daily maintenance and collection. Finally, compared to adding a separate pipe for collecting shrimp shells, even if it is pre-buried under the bottom of the shrimp pond, the dual-function design of the single pipe significantly reduces the difficulty of pipe construction and greatly reduces material and installation costs. It also reduces the risk of shrimp shells and excrement decomposing and spoiling due to long-term deposition in the dedicated shrimp shell collection pipe, providing a more economical solution for aquaculture farms.

[0026] Example: Reference Figure 1-3A double-cone baffle 2 is installed at the upper end of the bottom drain outlet 1 of the shrimp pond. Multiple top-level drainage holes 3 are provided on the outer surface of the double-cone baffle 2, and a bottom-level drainage hole 4 is provided at the lower end of the double-cone baffle 2. A rope fixing hole 5 is provided at the end of the double-cone baffle 2 opposite to the bottom-level drainage hole 4, and a lifting rope 6 is provided at the end of the rope fixing hole 5 opposite to the double-cone baffle 2. The pond-side water level tank is connected to the shrimp shell baffle via a pipe. The shrimp shell baffle has multiple small holes that allow only shrimp feces and fine particulate matter to pass through. When the shrimp shell baffle is pulled up using a rope to create a gap of a certain size, shrimp shells will flow through the gap to the shrimp shell collection basket. Otherwise, only shrimp feces, fine particulate matter, and water can flow through the filter holes to the shrimp shell collection basket. The pond-side water level tank contains a shrimp shell collection basket for collecting shrimp shells. The shrimp shell collection basket separates waste from shrimp shells through multiple drainage holes that allow only water flow and shrimp feces and other debris to pass through. This device utilizes water level differences to simultaneously collect shrimp waste and other wastewater through a circulating pipe, avoiding the need for separate shrimp shell collection pipes and baskets within the shrimp pond. It also prevents waste from deteriorating due to prolonged stagnant water in independent shrimp shell collection pipes. A water level control pipe is also installed in the side water level tank to maintain a stable water level in the pond. The entire pipeline is very simple and buried below the bottom of the shrimp pond, further optimizing space utilization, reducing interference with water flow and aquaculture operations, lowering aquaculture risks, and significantly reducing construction costs and difficulty.

[0027] Reference Figure 3 The outer surface of the bottom drainage hole 4 is provided with counterweight concrete 7. The counterweight concrete 7 may be placed on components such as shrimp shell and live shrimp baffles. By increasing the weight, it ensures that the baffles stably cover the bottom drain of the shrimp pond when not in operation, preventing shrimp shells or live shrimp from flowing out prematurely before the collection time.

[0028] Reference Figure 1 A culture pond 8 is set on the outer surface of the bottom drain 1 of the shrimp pond, and culture pond walls 9 are set around the culture pond 8. The culture pond 8 is the main space for shrimp growth, providing a living environment for shrimp, and is also the place where shrimp feces, shrimp shells and other waste are generated. The bottom drain in the center facilitates the collection of waste. The culture pond walls 9 form the boundary of the culture pond and play the role of enclosing the water body.

[0029] Reference Figure 4 A circulating water pipe 10 is installed on one side of the bottom drainage hole 4. The circulating water pipe 10 is a single shared pipe, which is responsible for transporting circulating water containing shrimp feces and other fine waste, and can also carry shrimp shells to the water level tank on the side of the pond when collecting shrimp shells, thus realizing a dual function.

[0030] Reference Figure 1 , Figure 4-5A side water level tank 11 is fixedly connected to one end of the wall 9 of the aquaculture pond. The side water level tank 11 is connected to the circulating water pipe and contains a shrimp shell collection basket for temporary storage of shrimp shells. At the same time, it maintains the stability of the water level in the aquaculture pond through the water level control pipe. It is an important component for the separation of waste and the transfer of water flow.

[0031] Reference Figure 5 A shrimp shell collection basket 12 is installed at one end of the circulating water pipe 10 relative to the bottom drain hole 4. The shrimp shell collection basket 12 is located in the water level tank on the side of the pool. Its filter holes only allow water flow and small debris such as shrimp feces to pass through, which can effectively intercept shrimp shells and is easy to remove and empty manually, so as to achieve centralized collection and treatment of shrimp shells.

[0032] Reference Figure 5 One end of the shrimp shell collection basket 12 is adjacent to the side of the circulating water pipe 10 and is equipped with a circulating water return pipe 13 for the microfilter. The circulating water return pipe 13 of the microfilter connects the water level tank on the side of the pool to the microfilter, and transports the water containing shrimp feces and other waste after being filtered by the shrimp shell collection basket to the microfilter for deep purification to ensure the quality of the circulating water.

[0033] Reference Figure 4 A water level control switch 15 is installed at one end of the circulating water pipe 10, and a water level control pipe 14 is installed at the other end of the circulating water pipe 10. The water level control pipe 14 is located inside the circulating water pipe 10 and precisely maintains the stability of the water level in the aquaculture pond by regulating the water flow rate, providing a suitable aquatic environment for shrimp growth and ensuring smooth aquaculture. The water level control switch 15 can control the on / off state of the water level control pipe or the water flow rate, assisting the water level control pipe in flexibly adjusting the water level in the aquaculture pond to meet the different water level requirements of shrimp at different growth stages.

[0034] The implementation principle of the shrimp shell collection device for aquaculture ponds that collects shrimp shells through a circulating water pipe according to this application is as follows: The pond-side water level tank is connected to the shrimp shell baffle via a pipe. The baffle has multiple small holes for shrimp feces and fine particles to pass through only. When the baffle is pulled up with a rope to create a gap, shrimp shells flow through the gap into the shell collection basket. Otherwise, only shrimp feces, fine particles, and water can flow through the filter holes to the collection basket. Inside the pond-side water level tank is a shell collection basket for collecting shrimp shells. This basket has multiple drainage holes for water and shrimp feces, separating waste from the shells. This device uses the water level difference and a circulation pipe to simultaneously achieve the return flow of wastewater (shrimp feces, etc.) and the collection of shrimp shells, thus avoiding the need for separate shell collection pipes and baskets within the shrimp pond and preventing waste from deteriorating due to prolonged stagnation in the independent shell collection pipes. The pond-side water level tank also includes a water level control pipe to maintain a stable water level in the pond. The entire pipeline is very simple and is buried below the bottom of the shrimp pond, which further optimizes the use of space in the pond, reduces interference with water flow and aquaculture operations, lowers aquaculture risks, and significantly reduces construction costs and construction difficulty.
