Description

Technical Field

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

[0002] Aquaculture risers are modern facilities that combine recirculating aquaculture technology with high-density intensive aquaculture to improve fish growth efficiency and product quality by simulating natural water flow environments.

[0003] Existing riser aquaculture tanks typically use multiple ballast tanks at the bottom, with the tank's height controlled by filling or draining water into these tanks. However, if one or more ballast tanks fail, the remaining tanks' weight can cause the tank to tilt, leading to fish swimming into the surrounding water and resulting in poor performance. Furthermore, because riser aquaculture tanks lack a feeding mechanism, workers often pour feed directly into the tank, causing food to concentrate and fish to huddle together, potentially injuring them and further reducing effectiveness. Therefore, we propose a riser aquaculture tank. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a liftable aquaculture trough.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a riseable aquaculture trough is designed, including a trough body, a shelf is installed at the bottom of the trough body by a connecting rod, and the bottom of the shelf is anchored to the bottom of the pond by a steel cable;

[0006] Several ballast coils are installed at the bottom of the tank. Each ballast coil is bent and fixed to the bottom edge of the tank. One end of each ballast coil is connected to a delivery pipe. Several submersible pumps are installed on the top of the shelf. One end of each delivery pipe is fixed to the outlet of the corresponding submersible pump. The other end of each ballast coil is connected to a vent pipe.

[0007] The top edge of the tank is fitted with a rim, and a pair of fixing blocks are installed on both sides of the top of the rim. Each pair of fixing blocks is rotatably connected to a screw rod, and a connecting block is threaded to the side of each screw rod. A hopper is connected between the tops of the two connecting blocks, and several discharge pipes are installed at the bottom of the hopper. The discharge pipes are located above the tank.

[0008] A mounting box is installed at one end of the top of the edging. One end of each lead screw extends into the mounting box, and a first synchronous pulley is installed at the end of each lead screw inside the mounting box. A drive motor is installed inside the mounting box, and a second synchronous pulley is connected to the output shaft of the drive motor. Both first synchronous pulleys are connected to the second synchronous pulleys through a synchronous belt.

[0009] Preferably, the bottom of the tank is inclined.

[0010] Preferably, a fish-blocking net is installed inside the tank.

[0011] Preferably, the end of the vent pipe away from the ballast coil extends above the tank body, and a vent valve is installed on the end of the vent pipe away from the ballast coil.

[0012] Preferably, each discharge pipe is equipped with a valve.

[0013] Preferably, the bottom of the hopper is inclined.

[0014] Preferably, each lead screw has two telescopic covers on its side, one end of each telescopic cover is fixed to the side of the corresponding connecting block, and the other end of each telescopic cover is fixed to the side of the corresponding fixing block, and there is a gap between the inner wall of the telescopic cover and the side of the lead screw.

[0015] The design scheme proposed in this utility model has the following beneficial effects in application:

[0016] 1.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-4 A liftable aquaculture tank includes a tank body 1. A shelf 13 is installed at the bottom of the tank body 1 via a connecting rod 12. The bottom of the shelf 13 is anchored to the bottom of the pond via a steel cable. By cooperating with the steel cable and the shelf 13, the tank body 1 can be installed in a preset position inside the pond, so that aquaculture can be carried out in the tank body 1.

[0026] It should be noted that the bottom of the tank 1 is inclined, and a fish barrier net 7 is installed inside the tank 1. In this way, feed residue and fish feces and other impurities in the tank 1 will flow from the bottom of the tank 1 through the fish barrier net 7 into the sludge collection area at the other end of the tank 1. This can prevent impurities from polluting the water where the fish are located, improve the use effect, and the fish barrier net 7 can also block the fish and prevent them from swimming into the sludge collection area inside the tank 1, so that the impurities collected in the sludge collection area will not cause any obstruction.

[0027] like Figure 1 and Figure 4 As shown, several ballast coils 18 are provided at the bottom of the tank 1. Each ballast coil 18 is bent and fixed to the bottom edge of the tank 1. In this way, the ballast coils 18 will evenly distribute the weight at the bottom of the tank 1. When one or more ballast coils 18 are damaged, the other ballast coils 18 will still evenly distribute the weight at the bottom of the tank 1, so that the tank 1 remains balanced.

[0028] like Figure 1 and Figure 4As shown, one end of each ballast coil 18 is connected to a delivery pipe 19. Several submersible pumps 20 are installed on the top of the shelf 13. One end of each delivery pipe 19 is fixed to the outlet of the corresponding submersible pump 20, and the other end of each ballast coil 18 is equipped with a vent pipe 2. The submersible pump 20 is a double-suction submersible pump. In actual use, the submersible pump 20 can deliver water from the pond to the ballast coil 18. Excess air in the ballast coil 18 can be discharged through the vent pipe 2, thus increasing the weight of the ballast coil 18 and causing the tank 1 to move downward. When it is necessary to control the tank 1 to rise, the submersible pump 20 is reversed, so that the outlet of the submersible pump 20 becomes the inlet, which can discharge the water in the ballast coil 18. At the same time, external air can be delivered to the ballast coil 18 through the vent pipe 2, reducing the weight of the ballast coil 18 and allowing the tank 1 to move upward, thus completing the adjustment.

[0029] The end of the vent pipe 2 away from the ballast coil 18 extends above the tank body 1, and a vent valve 17 is installed on the end of the vent pipe 2 away from the ballast coil 18. The opening and closing of the vent pipe 2 can be controlled by controlling the opening and closing of the vent valve 17. In this way, when the submersible pump 20 is working, the operator can open the vent valve 17 to keep the internal and external pressure of the ballast coil 18 balanced. When the submersible pump 20 is not working, the operator can close the vent valve 17 to prevent external impurities from entering the vent pipe 2 and clogging the vent pipe 2 or the ballast coil 18.

[0030] like Figure 1 and Figure 2 As shown, a rim 11 is installed on the top edge of the tank 1. A pair of fixing blocks 10 are installed on both sides of the top of the rim 11. A screw rod 6 is rotatably connected between each pair of fixing blocks 10. A connecting block 5 is threaded to the side of each screw rod 6. A hopper 9 is connected between the tops of the two connecting blocks 5. Several discharge pipes 8 are installed at the bottom of the hopper 9. The discharge pipes 8 are located above the tank 1. In actual use, the staff can pour the feed into the hopper 9, and then the feed will be discharged into the tank 1 through the discharge pipes 8 to feed the aquatic products.

[0031] It should be noted that, as Figure 5 As shown, each discharge pipe 8 is equipped with a valve 21. The opening and closing of the discharge pipe 8 can be controlled by the valve 21. When the staff is feeding, the valve 21 can be opened to discharge the feed in the hopper 9 through the discharge pipe 8. When feeding is not needed, the valve 21 can be closed so that the feed in the hopper 9 will not be discharged along the discharge pipe 8.

[0032] like Figure 1 and Figure 3As shown, a mounting box 3 is installed at one end of the top of the circumference 11. One end of each lead screw 6 extends into the mounting box 3, and a first synchronous pulley 15 is installed at the end of each lead screw 6 inside the mounting box 3. A drive motor 14 is installed inside the mounting box 3. The output shaft of the drive motor 14 is connected to a second synchronous pulley 16. Both first synchronous pulleys 15 are connected to the second synchronous pulley 16 via a synchronous belt. In actual use, the operator controls the drive motor 14 to work. The drive motor 14 can synchronously drive the two lead screws 6 to rotate through the cooperation of the first synchronous pulley 15 and the second synchronous pulley 16, thereby controlling the hopper 9 to move horizontally along the top of the trough 1, so that the feed discharged from the discharge pipe 8 is evenly distributed, improving the use effect.

[0033] Specifically, when using this invention, if the height of the tank 1 needs to be adjusted, the operator controls the submersible pump 20 to work, and at the same time opens the vent valve 17. The submersible pump 20 draws water out of the ballast coil 18 through the delivery pipe 19, and external air is simultaneously delivered into the ballast coil 18 through the vent pipe 2. This reduces the weight of the ballast coil 18, and the tank 1 rises under the buoyancy of the water. Furthermore, if one of the ballast coils 18 is damaged, the remaining ballast coils 18 will still maintain the stability of the tank 1 and will not cause the tank 1 to tilt, thus improving the usage effect. When feeding the fish, the operator pours the feed into the feed bin 9, and then opens the valve 21 while controlling the drive motor 14 to work. The drive motor 14, under the action of the first synchronous pulley 15 and the second synchronous pulley 16, synchronously drives the two lead screws 6 to rotate. The lead screws 6 will drive the feed bin 9 to move horizontally along the tank 1 through the connecting block 5, increasing the area of ​​feed delivered by the discharge pipe 8, preventing the fish from crowding together to compete for food, and improving the usage effect.

[0034] Furthermore, the bottom of the feed hopper 9 is set at an angle, so that no feed residue will be generated when the feed in the feed hopper 9 is put in.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, each lead screw 6 has two telescopic covers 4 on its side. One end of each telescopic cover 4 is fixed to the side of the corresponding connecting block 5, and the other end of each telescopic cover 4 is fixed to the side of the corresponding fixing block 10. There is a gap between the inner wall of the telescopic cover 4 and the side of the lead screw 6. In this way, the telescopic cover 4 can cover the lead screw 6 and isolate it from the external environment. This prevents impurities from adhering to the lead screw 6 and also prevents it from being corroded by the humid environment, thus improving the protection effect.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
