Description

Technical Field

[0001] This utility model belongs to the technical field of fish farming tanks, specifically relating to a floating fish farming tank. Background Technology

[0002] Because conventional pond aquaculture suffers from problems such as substandard wastewater discharge, large input of feed and medicine, difficulty in water quality control and disease management, risks to the quality and safety of aquatic products, inconvenience in management and harvesting, high labor intensity, and high labor costs, the fish farming industry built a floating circular aquaculture tank recirculating aquaculture system in conventional aquaculture ponds in 2016, which allows for intensive fish farming in the tank.

[0003] In the existing pond culture tank farming model, fish move around at the bottom of the tank. Harvesting the fish requires a lot of manpower and time to use nets to scoop them up from the bottom of the tank. Because the water is deep and the fish are located at the bottom of the tank, the labor intensity is high and the harvesting efficiency is low. In addition, the fish are easily damaged, which affects the quality and survival rate of the fish. Utility Model Content

[0004] The purpose of this invention is to provide a floating fish farming tank to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a floating fish farming tank, comprising:

[0006] The culture tank is provided in several parts and the several culture tanks are connected by floating passageways. An aeration disc is provided inside the culture tank. The top of the aeration disc is connected to a first air pump provided on the surface of the pond through an aeration pipe. A fixing ring is connected to the top of the culture tank. A fishing net is provided inside the culture tank and the top of the fishing net is connected to the fixing ring.

[0007] An annular airbag is provided, and the annular airbag is respectively fitted onto the outer surface of the aquaculture tank. By inflating the annular airbag, the annular airbag can lift the aquaculture tank in the pond.

[0008] By deflating the annular airbag, the aquaculture tank is allowed to sink into the pond.

[0009] Preferably, the surface of the pond is further provided with a second air pump, and the air outlet of the second air pump is connected to the annular airbag through an inflation pipe. The surface of the annular airbag is provided with an exhaust pipe, and the surface of the exhaust pipe is provided with a control valve.

[0010] Preferably, the top of the fishing net is provided with several loops, and the fishing net is tied to the surface of the fixed loops by a fixing rope passing through the loops.

[0011] Preferably, a sludge collection well is provided between several breeding tanks, and a sludge discharge pipe is provided at the bottom of the breeding tank and the sludge discharge pipe is connected to the sludge collection well through a first connecting pipe.

[0012] Preferably, the surface of the pond is provided with a sewage discharge trough, and the sewage pump in the sewage collection well is connected to the sewage discharge trough through a second connecting pipe.

[0013] Preferably, the pond is equipped with several water pumps, and the water pumps are connected to the breeding tanks through a third connecting pipe.

[0014] Preferably, the surface of the aeration disc is provided with a plurality of aeration heads.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] During harvesting, the ring-shaped air bladder on the outer surface of the aquaculture tank can be inflated by controlling a second air pump. The rapid expansion of the air bladder generates strong buoyancy, causing the aquaculture tank to rise steadily. Under the action of the air bladder, the aquaculture tank is raised to a higher position in the pond. As the aquaculture tank rises, the fishing net inside is also pulled up with it. As the fishing net rises, the fish gradually gather and are lifted up, making it easier for aquaculture workers to easily scoop the fish out of the bottom of the aquaculture tank, thus completing the harvesting operation. This greatly shortens the harvesting time and significantly improves the harvesting efficiency.

[0017] The well-designed collection wells, interconnected sewage pipes, connecting pipes, and sewage pumps among multiple aquaculture tanks constitute an efficient sewage system. During the aquaculture process, pollutants such as fish excrement and uneaten feed fall from the mesh of the fishing net into the bottom of the aquaculture tank under the influence of gravity, and flow into the collection well through the sewage pipe at the bottom of the aquaculture tank. By periodically starting the sewage pump, the sewage and impurities in the collection well can be discharged into the sewage trough on the surface of the pond through the second connecting pipe for centralized treatment, maintaining a stable and good water quality environment in the aquaculture tanks.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-3 The floating fish farming tank shown includes:

[0024] A culture tank 1 is provided, and the culture tanks 1 are connected to each other by a floating passageway 2. An aeration disc 3 is provided inside the culture tank 1. The top of the aeration disc 3 is connected to a first air pump 6 provided on the surface of the pond 5 through an aeration pipe 4. A fixing ring 7 is connected to the top of the culture tank 1. A fishing net 24 is provided inside the culture tank 1 and the top of the fishing net 24 is connected to the fixing ring 7.

[0025] An annular airbag 8 is provided, and the annular airbag 8 is respectively fitted onto the outer surface of the aquaculture tank 1. By inflating the annular airbag 8, the annular airbag 8 can lift the aquaculture tank 1 in the pond 5.

[0026] By deflating the annular airbag 8, the aquaculture tank 1 is allowed to sink into the pond 5.

[0027] The surface of the pond 5 is also provided with a second air pump 9, and the air outlet of the second air pump 9 is connected to the annular airbag 8 through an inflation pipe 10. The surface of the annular airbag 8 is provided with an exhaust pipe 11, and the surface of the exhaust pipe 11 is provided with a control valve 12.

[0028] The top of the fishing net 24 is provided with several loops 13. The fishing net 24 is tied to the surface of the fixed ring 7 by a fixing rope 23 passing through the loops 13. During long-term aquaculture, the fishing net 24 may be damaged or have clogged mesh due to the growth and activity of fish and natural wear and tear. At this time, the fishing net 24 needs to be replaced or cleaned and replenished in time. When the fishing net 24 needs to be disassembled, the operator only needs to untie the connection between the fixing rope 23 and the fixed ring 7. Due to the presence of the loops 13, the fixing rope 23 can be easily pulled out from the loops 13, thereby quickly removing the fishing net 24 from the aquaculture tank 1, which greatly shortens the maintenance time.

[0029] A collection well 14 is provided between several breeding tanks 1. A sewage pipe 15 is provided at the bottom of each breeding tank 1 and is connected to the collection well 14 through a first connecting pipe 16. A sewage trough 17 is provided on the surface of the pond 5. A sewage pump 19 provided in the collection well 14 is connected to the sewage trough 17 through a second connecting pipe 18. The sewage pump 19 can discharge the sewage and impurities in the collection well 14 into the sewage trough 17 on the surface of the pond 5 through the second connecting pipe 18 for centralized treatment.

[0030] The pond 5 is equipped with several water pumps 20, and the water pumps 20 are connected to the breeding tank 1 through the third connecting pipe 21. The water pumps 20 can transport water to the breeding tank 1 through the third connecting pipe 21 to maintain the circulation of water in the breeding tank 1.

[0031] The surface of the aeration disc 3 is provided with several aeration heads 22. Air can be transported to the aeration disc 3 inside the aquaculture tank 1 through the aeration pipe 4. The air is dispersed into tiny bubbles by the aeration heads 22 on the aeration disc 3 and evenly integrated into the water in the aquaculture tank 1.

[0032] In this floating fish farming tank, under normal farming conditions, the annular airbag 8 is in a deflated state, and the farming tank 1 sinks to an appropriate depth in the pond 5. The fish move within the fishing net 24 inside the farming tank 1, while the first air pump 6 continuously operates, delivering air through the aeration pipe 4 to the aeration disc 3 inside the farming tank 1. The air is dispersed into tiny bubbles by the aeration heads 22 on the aeration disc 3, evenly dispersing into the water in the farming tank 1, increasing dissolved oxygen and providing sufficient oxygen for the fish. Meanwhile, the water pump 20 in the pond 5 delivers water through the third connecting pipe 21 to... The breeding tank 1 maintains the circulation of water within it, ensuring uniform water quality suitable for fish growth. Simultaneously, fish excrement and leftover feed fall from the mesh of the fishing net 24 into the bottom of the breeding tank 1 under gravity. They are then pumped into the sludge collection well 14 via the sewage pipe 15 at the bottom of the breeding tank 1 and the first connecting pipe 16 by an external cleaning pump. By periodically activating the sewage pump 19, the sewage and impurities in the sludge collection well 14 can be discharged into the sewage trough 17 on the surface of the pond 5 via the second connecting pipe 18 for centralized treatment.

[0033] When it is time to catch fish, the second air pump 9 on the surface of pond 5 is activated. Gas is quickly injected into the annular airbag 8 through the air inflator 10. As the air in the annular airbag 8 increases, its volume expands, and the buoyancy generated gradually increases. This overcomes the weight of the aquaculture tank 1 and the resistance of the water, causing the aquaculture tank 1 to rise until it is raised to a certain position above the water surface of pond 5. At the same time as the aquaculture tank 1 is raised, the fishing net 24 inside the aquaculture tank 1 is also pulled up along with it. As the fishing net 24 rises, the fish will gradually gather and be lifted up, allowing the aquaculture personnel to easily scoop out the fish from the net 24 and complete the harvesting operation. After the harvesting is completed, the control valve 12 of the exhaust pipe 11 on the surface of the annular airbag 8 is opened to release the gas inside the airbag, causing the aquaculture tank 1 to sink back into pond 5 and return to normal aquaculture status.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
