Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, specifically to an aquaculture device for white-whiskered carp. Background Technology

[0002] In traditional flow-through fish farming systems, the water intake method often lacks planning, making it difficult to achieve a uniform distribution of water flow within the cages. Excessively high flow velocities in certain areas can easily cause stress in the fish, hindering normal growth; while areas with excessively slow flow velocities will suffer from insufficient dissolved oxygen, leading to the accumulation of uneaten food and feces, deterioration of water quality, and ultimately increasing the probability of fish diseases.

[0003] Existing aquaculture devices suffer from imprecise water flow guidance designs, hindering efficient utilization of water kinetic energy for oxygenation and waste removal, resulting in low aquaculture efficiency. Furthermore, some devices equipped with water circulation systems suffer from complex structures and high costs, particularly prominent in small-scale aquaculture settings. These issues manifest as high energy consumption, easy clogging of net cages affecting water exchange, leading to water quality deterioration, insufficient dissolved oxygen, and maintenance difficulties. To address these problems, we have developed a specialized aquaculture device for the coarse-whiskered white carp. Summary of the Invention

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a breeding device for white-whiskered carp. The device features a double-diversion pipe and a diversion sprayer to achieve water circulation and oxygenation, combined with an automatic cleaning unit and an overflow-sewage system to maintain water quality. It employs an 80-mesh breeding cage, fixing device, and isolation net to ensure the safe growth of fish while increasing breeding density. It also boasts advantages of energy saving, environmental protection, and high survival rate, making it suitable for large-scale healthy aquaculture and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a breeding device for white carp with coarse whiskers, comprising a breeding pond and a water storage pond;

[0006] Aquaculture pond: Diversion pipes are placed on both sides of the top surface. A water pump is fixed to the bottom of the water storage pond. The outlet of the water pump is connected to the inlet of a PVC water pipe. The two outlets of the PVC water pipe are connected to the inlets of the two diversion pipes respectively. A main water valve is installed on the outside of the PVC water pipe. Diversion sprayers are evenly installed on the surface of the diversion pipe. An aquaculture net cage is placed inside the aquaculture pond. The surface of the aquaculture net cage is evenly opened with 80-mesh mesh. A cleaning unit is provided inside the aquaculture pond.

[0007] The system also includes a controller, which is located on the left side of the aquaculture pond. The input terminals of the water pump and the main water valve are electrically connected to the output terminal of the controller, and the input terminal of the controller is electrically connected to the output terminal of an external power source.

[0008] The water pump is started to transport water from the reservoir to the two branch pipes through PVC pipes. The branch water sprayers can continuously flow water into the breeding cages to increase the dissolved oxygen in the water, thus providing sufficient oxygen for the white-whiskered carp.

[0009] Furthermore, the cleaning unit includes a water flow pressure divider valve, a cleaning pipe, and spray nozzles. The water flow pressure divider valve is installed on the left end of the rear diversion pipe. The outlet of the water flow pressure divider valve is connected to the inlet of the cleaning pipe. The cleaning pipe is located inside the aquaculture pond. Spray nozzles are evenly installed on the surface of the cleaning pipe. When the water flow pressure divider valve is activated, water is sprayed out through the spray nozzles to flush the bottom of the aquaculture pond, thereby solving the problem of excrement accumulation affecting water quality.

[0010] Furthermore, it also includes a drainage pipe, an overflow trough, and a sewage pipe. The overflow trough is located at the top of the right side inside the aquaculture pond. The drainage pipe is installed at the top of the right side of the aquaculture pond and is connected to the overflow trough. The sewage pipe is installed at the bottom of the right side of the aquaculture pond. The overflow trough can drain floating uneaten feed, oil, feces, and scum when the liquid level rises, and the sewage is discharged by gravity through the drainage pipe. The sewage pipe can discharge excrement and other impurities accumulated at the bottom of the aquaculture pond.

[0011] Furthermore, it also includes fixing ropes and fixing objects. There are four fixing ropes, which are installed in pairs on the front and back sides of the aquaculture cage. The bottom end of the fixing rope is fitted with a fixing object. The fixing rope and the fixing object can fix the aquaculture cage to different heights inside the aquaculture pond, preventing it from shifting due to water flow and protecting the fish from abrasion.

[0012] Furthermore, it also includes an isolation net and a net cage cover. The isolation net is fixed inside the aquaculture net cage, and the net cage cover is hinged to the top surface of the aquaculture net cage. The isolation net can isolate the farmed fish and prevent the fish fry from crossing over, while the hinged net cage cover can prevent the fish fry from escaping.

[0013] Furthermore, it also includes four plastic clips, which are fixed in pairs on the front and back sides of the top surface of the aquaculture pond. The inside of the plastic clips is engaged with the outside of the diversion pipe. The plastic clips can fix the diversion pipe and also facilitate subsequent disassembly.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This breeding device for white carp with coarse whiskers has the following advantages:

[0015] 1. By starting the water pump, the water inside the reservoir is transported through PVC water pipes to the two branch pipes. The branch water sprayers can continuously flow water into the breeding net cages to increase the dissolved oxygen content of the water, thus providing sufficient oxygen for the white carp. At the same time, the water pressure generated by the natural drop of the terrain can also be used to transport water to the breeding pond.

[0016] 2. By activating the water flow pressure divider valve, water is sprayed through the spray head to flush the bottom of the breeding pond, thus solving the problem of excrement accumulation affecting water quality. The overflow trough can drain floating uneaten feed, oil, feces and foam when the liquid level rises, and the waste is discharged by gravity through the drainage pipe. The sewage pipe can discharge excrement and other impurities accumulated at the bottom of the breeding pond.

[0017] 3. By using fixing ropes and other anchors, the aquaculture cages can be fixed at different heights inside the aquaculture pond to prevent displacement due to water flow and to protect the fish from abrasion. The isolation nets can isolate the farmed fish and prevent the fry from crossing over, while the hinged cage covers can prevent the fry from escaping. Attached Figure Description

[0025] The system also includes a controller 18, located on the left side of the aquaculture pond 1. The input terminals of the water pump 4 and the main water valve 17 are electrically connected to the output terminal of the controller 18, which in turn is electrically connected to the output terminal of an external power supply. Activating the water pump 4 transports water from the reservoir 3 through the PVC water pipe 5 to the two branch pipes 6.

The sewage pipe 11 allows the aquaculture fish to pass through the water tank. The system removes accumulated excrement and other impurities from the bottom of pond 1. It also includes fixing ropes 12 and fixing objects 13. Four fixing ropes 12 are installed in pairs on the front and rear sides of the aquaculture cage 8. The bottom end of each fixing rope 12 is fitted with a fixing object 13. The fixing ropes 12 and fixing objects 13 can fix the aquaculture cage 8 to different heights inside the aquaculture pond 1, preventing displacement due to water flow and protecting the fish from abrasion. It also includes an isolation net 14 and a cage cover 15. The isolation net 14 is fixed inside the aquaculture cage 8, and the cage cover 15 is hinged to the top surface of the aquaculture cage 8.

[0028] Experimental Example 1

[0029] The experiment was formally conducted in the reservoir of the Aquaculture Engineering Center of Tongren University. The specific steps are as follows:

[0030] (1) Selection and acclimatization of juvenile fish: Healthy, disease-free juvenile white carp from the same breeding batch were selected and temporarily housed in aquaculture cage 8 (length × width × height = 260cm × 48cm × 61cm) with 80 mesh holes at the Aquaculture Engineering Center of Tongren University for acclimatization. During the temporary housing period, the juvenile fish were acclimatized with commercial feed twice a day for 8 weeks.

[0031] (2) Setting up water source control components: Install a water pump 4 at the water source intake site, connect a 50mm PVC water pipe 5, connect the PVC water pipe 5 to a 25mm diversion pipe 6 located directly above the net cage layout, and install an adjustable diversion sprayer 7 on the diversion pipe 6.

[0032] (3) Setting up the water flow device: Before the formal experiment begins, fill the breeding pond 1 of the Aquaculture Engineering Center of Tongren College with water. In the breeding pond 1, set up a breeding net cage 8 with a length × width × height of 260cm × 48cm × 61cm and an 80-mesh net cage cover 15. Set up an isolation net 14 in the middle to prevent the fish fry from crossing. A total of 9 net cages are set up, with a total of 18 grids. 20 juvenile white carp are placed in each grid. The water flow of the diversion sprayer 7 set above each grid can just fall into the grid. The water flow rate is 2L / min / grid. There is a water outlet set above each grid, with a total of 20 water outlets. The total flow rate of the water storage tank is 40L / min.

[0033] (4) Dissolved oxygen monitoring: Dissolved oxygen was measured at 7:00 and 17:00 every day during the entire 95-day culture period. The water temperature during the experiment was 10-24℃; the water flow was uninterrupted except during feeding, and the total flow rate of culture pond 1 was 40L / min. During the experiment, the dissolved oxygen in the water was >7mg / L, the pH was 6.5-7.5, the ammonia nitrogen was <0.1mg / L, and the nitrite was <0.01mg / L.

[0034] In summary, this study systematically designed the equipment and dissolved oxygen monitoring and control system for the rearing of juvenile whitebait. Regarding the equipment, water flow control was achieved by installing a water pump at the water source and connecting it to a 50mm PVC water pipe, a 25mm branch pipe, and an adjustable branch sprayer. Except for feeding, the water flow was maintained continuously, ensuring that dissolved oxygen remained above 7mg / L throughout the rearing process, while maintaining a pH of 6.5-7.5, ammonia nitrogen <0.1mg / L, and nitrite <0.01mg / L. This water quality provided a stable and suitable dissolved oxygen environment and water quality conditions for juvenile rearing, demonstrating high feasibility and promotional value in whitebait farming.

[0035] It is worth noting that the controller 18 disclosed in the above embodiments uses the STM32 model, while the water pump 4 can be freely configured according to the actual application scenario. It is recommended to use the CDLF42-60 model water pump, and the main water valve 17 can be a valve of model D671X-16. The controller 18 controls the operation of the water flow pressure divider valve 21, the water pump 4, and the main water valve 17 using methods commonly used in the prior art.
