Description

Aquaculture tank Technical Field

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

[0002] Aquaculture tanks are specialized containers or facilities used for the artificial cultivation of aquatic organisms (such as fish, shrimp, and shellfish). They are usually made of materials such as plastic, concrete, stainless steel, or canvas, and come in various designs such as round, rectangular, or stepped. They can be equipped with recirculating aquaculture systems (RAS), aerators, and filtration devices to achieve efficient aquaculture.

[0003] Traditional aquaculture tanks rely on physical filtration to remove large particles of impurities such as uneaten feed and feces from the water. However, due to the difficulty in strengthening the internal structure, the structural stability of the tank is greatly reduced. This is especially true when the tank is large, which can cause the side walls and bottom of the tank to deform or even crack under water pressure. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides an aquaculture tank, which aims to improve the traditional aquaculture tank. Due to the difficulty in strengthening the internal structure, the side walls and bottom of the tank are prone to deformation or even cracking under water pressure.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An aquaculture tank includes a first filter tank shell, a second filter tank shell disposed on the lower surface of the first filter tank shell, a first pipe fixedly connected inside the second filter tank shell, a water pump fixedly connected to the outer wall of the first pipe, a second pipe fixedly connected to the output end of the water pump, and an aquaculture tank body fixedly connected to the outer wall of the second pipe.

[0007] Preferably, the aquaculture tank body includes an epoxy resin coating, and the outer wall of the epoxy resin coating is sequentially connected with a rubber liner, a support layer and a wear-resistant layer.

[0008] Preferably, a third pipe is fixedly connected inside the aquaculture tank body, and the outer wall of the third pipe is fixedly connected inside the outer shell of the first filter tank.

[0009] Preferably, a protective shell is provided on the upper surface of the first filter water tank shell, and a connecting rod is rotatably connected inside the protective shell.

[0010] Preferably, the outer wall of the connecting rod is rotatably connected to the inside of the second filter tank shell, and a rotating block is fixedly connected to the top end of the connecting rod.

[0011] Preferably, a knob is fixedly connected to the upper surface of the rotating block.

[0012] Preferably, a spring is provided on the lower surface of the rotating block, and the bottom end of the spring is located inside the protective shell.

[0013] Preferably, the outer wall of the rotating block is rotatably connected to the inside of the protective shell, and the outer wall of the connecting rod is rotatably connected to the inside of the first filter tank shell.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the rubber liner is fixed by an epoxy resin coating, and then the support layer is fixed along with the rubber liner. Then, the wear-resistant layer is fixed under the support of the support layer, and finally the purpose of strengthening the internal structure of the aquaculture tank is achieved. It can effectively disperse the water pressure, the impact force of the aquatic animals' activities and the weight of the aquaculture tank itself, making the tank more stable.

[0016] 2. In this utility model, rotating the knob drives the rotating block to rotate, and then the connecting rod slides under the drive of the rotating block. Subsequently, the spring will stretch as the rotating block slides, and finally achieve the purpose of replacing the filter screen. Replacing the filter screen can remove impurities, uneaten food, and feces, effectively filter out suspended particles and organic matter in the water, keep the water clear, reduce the content of harmful substances in the water, reduce the risk of eutrophication, and provide a cleaner and healthier living environment for aquatic animals.

[0026] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Referring to Figures 1-3, one embodiment of this utility model is provided: an aquaculture tank, including a first filter tank shell 1, a second filter tank shell 2 is provided on the lower surface of the first filter tank shell 1, a first pipe 3 is fixedly connected inside the second filter tank shell 2, a water pump 4 is fixedly connected to the outer wall of the first pipe 3, a second pipe 5 is fixedly connected to the output end of the water pump 4, and an aquaculture tank body 6 is fixedly connected to the outer wall of the second pipe 5.

[0028] Specifically, the second filter tank shell 2 and the first filter tank shell 1 are used to protect the internal structure and prevent damage. The first pipe 3 and the second pipe 5 are used to transport the filtered liquid out. The water pump 4 is used to quickly carry out the filtered liquid. The aquaculture tank is circular and has a water flow environment without sharp corners inside, which can reduce the stress response of farmed organisms caused by water flow impact or collision at corners.

[0029] Referring to Figures 4-6, the aquaculture tank body 6 includes an epoxy resin coating 601. The outer wall of the epoxy resin coating 601 is sequentially connected to a rubber liner 602, a support layer 603, and a wear-resistant layer 604. The aquaculture tank body 6 is fixedly connected to a third pipe 7 inside. The outer wall of the third pipe 7 is fixedly connected to the inside of the first filter tank shell 1.

[0030] Specifically, the epoxy resin coating 601 has good corrosion resistance, effectively resisting the erosion of various chemicals in the water and extending the service life of the aquaculture tank. The rubber lining 602 has good flexibility, which can buffer the impact of the aquaculture organisms on the tank wall and protect the structure of the aquaculture tank from damage. The support layer 603 can withstand a large weight, preventing the aquaculture tank from deforming, collapsing or being damaged due to unbearable load. The wear-resistant layer 604 can effectively resist friction and wear, reducing damage to the surface of the tank. The third pipe 7 is used to transfer the liquid inside the aquaculture tank body 6 to the filter device, thereby extending the service life of the aquaculture tank. This can achieve the effect of strengthening the internal structure of the aquaculture tank body 6 and effectively dispersing the water pressure, the impact force of the aquatic animals' activities and the weight of the aquaculture tank itself.

[0031] Referring to Figures 5-7, a protective shell 8 is provided on the upper surface of the first filter tank shell 1, and a connecting rod 9 is rotatably connected inside the protective shell 8; the outer wall of the connecting rod 9 is rotatably connected inside the second filter tank shell 2, and a rotating block 10 is fixedly connected to the top end of the connecting rod 9; a knob 11 is fixedly connected to the upper surface of the rotating block 10; a spring 12 is provided on the lower surface of the rotating block 10, and the bottom end of the spring 12 is located inside the protective shell 8; the outer wall of the rotating block 10 is rotatably connected inside the protective shell 8, and the outer wall of the connecting rod 9 is rotatably connected inside the first filter tank shell 1.

[0032] Specifically, rotating the knob 11 drives the rotating block 10 to rotate, which in turn drives the connecting rod 9 to rotate. The protective shell 8 supports the spring 12 for tension and protects the internal structure. When the knob 11 is rotated, the spring 12 is stretched, which in turn causes the rotating block 10 and the connecting rod 9 to slide upward, thereby allowing the first filter tank shell 1 and the second filter tank shell 2 to be quickly disassembled. When the knob 11 is pressed and rotated, the spring 12 is compressed, which in turn causes the connecting rod 9 to slide downward and fix the first filter tank shell 1 and the second filter tank shell 2. The spring 12, through its own characteristics, can prevent the connecting rod 9 from rotating accidentally inside the second filter tank shell 2, thus achieving the effect of replacing the filter screen, keeping the water clear, reducing the content of harmful substances in the water, reducing the risk of eutrophication, and providing a cleaner and healthier living environment for aquatic animals.

[0033] Working principle: When the aquaculture tank is used, when the inside of the aquaculture tank body 6 is filled with liquid, the epoxy resin coating 601 supports and fixes the rubber liner 602, and then the support layer 603 is fixed to the outer wall of the rubber liner 602. Thus, the wear-resistant layer 604 is fixed to the outer wall of the support layer 603, thereby strengthening the internal structure of the aquaculture tank body 6. It can effectively disperse the water pressure, the impact force of aquatic animal activity, and the weight of the tank itself, making the tank more stable.

[0034] When it is necessary to replace the internal filter screen of the filter device, the rotating block 10 is rotated by turning the knob 11, which stretches the spring 12 and drives the connecting rod 9 to slide, loosening the connection between the first filter tank shell 1 and the second filter tank shell 2. This allows the filter screen to be replaced. Replacing the filter screen can remove impurities, uneaten food, and feces, effectively filtering out suspended particles and organic matter in the water, keeping the water clear, reducing the content of harmful substances in the water, reducing the risk of eutrophication, and providing a cleaner and healthier living environment for aquatic animals.

[0035] 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.
