Technical Field

[0001] This utility model belongs to the field of aquaculture equipment technology, specifically relating to a factory-scale multi-layer circular culture pond. Background Technology

[0002] With the rapid development of the aquaculture industry towards factory-style and intensive farming, circular ponds are widely used in factory-style fish farming due to their advantages such as uniform water flow, easy collection of uneaten feed and feces, and convenient management. In actual farming, when the number of ponds is limited, it is often necessary to mix fish of different sizes. Existing factory-style circular ponds are usually single-space structures. When different sizes of fish are mixed, larger fish tend to compete for food, suppressing the growth of smaller fish, resulting in slow growth of smaller fish and low farming efficiency. Utility Model Content

[0003] This invention provides a factory-produced multi-layered circular culture tank to at least solve some of the aforementioned technical problems.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A factory-produced multi-layer circular rearing tank includes an outer tank body with an inlet, a fixing mechanism detachably mounted on the top of the outer tank body, a fixed net ring mounted on the fixing mechanism and located within the outer tank body, a movable net ring slidably mounted within the fixed net ring, and an adjustment mechanism mounted on the fixing mechanism for adjusting the position of the movable net ring.

[0005] Furthermore, the fixed net ring includes an annular support A located at the bottom of the fixed mechanism, several mounting sleeves arranged around the annular support, several annular supports B located in the outer pool and connected to all the mounting sleeves, and a first isolation net arranged around the annular support B; the movable net ring is slidably installed on the mounting sleeves.

[0006] Furthermore, the movable mesh ring includes a sliding rod slidably disposed within the mounting sleeve, an annular bracket C connected to all the sliding rods, and a second isolation mesh disposed on the inner wall of the annular bracket C; the sliding rod is connected to the adjustment mechanism.

[0007] Furthermore, the mounting sleeve is provided with a limiting groove, and the sliding rod is provided with a limiting block that matches the limiting groove. The limiting block is slidably installed in the limiting groove and slides in the length direction of the limiting groove; the annular bracket C is installed on the limiting block.

[0008] Furthermore, the adjustment mechanism includes a pair of mounting seats on the fixed mechanism, a rotating shaft between the two mounting seats, a winding mechanism on the rotating shaft, and a drive motor on the fixed mechanism and connected to the rotating shaft.

[0009] Furthermore, the winding mechanism includes two winding reels mounted on a rotating shaft and rotating synchronously with the rotating shaft, and a pull rope with one end connected to the winding reels and the other end connected to the movable wire mesh.

[0023] Example 1. As... Figure 1-6 As shown, the present invention provides a factory-produced multi-layer circular breeding pool, including an outer pool body 3 with an inlet 1, a fixing mechanism located on the top of the outer pool body 3, a fixed net ring 4 located on the fixing mechanism and inside the outer pool body 3, a movable net ring 5 slidably located inside the fixed net ring 4, and an adjustment mechanism located on the fixing mechanism for adjusting the position of the movable net ring 5.

[0024] In this invention, the fixing mechanism is bolted to the top of the outer pool body 3, facilitating disassembly. When not in use, the fixed net ring 4, adjusting mechanism, and movable net ring 5 can be removed from the fixing mechanism, allowing the outer pool body 3 to be used independently. Simultaneously, the outer pool body 3, fixed net ring 4, and movable net ring 5 work together to effectively accommodate mixed-culture of fish of different sizes. Furthermore, since the movable net ring 5 is slidably installed within the fixed net ring 4 and connected to the adjusting mechanism, its position within the fixed net ring 4 can be adjusted, thereby regulating the culture space within the fixed net ring 4. This allows for adjustments to the outer pool body based on fish size and density. The space provided by the movable net ring 3 or the fixed net ring 4 facilitates fish farming. During use, the movable net ring 5 is slidably installed inside the fixed net ring 4, causing it to automatically descend under gravity. Simultaneously, an adjustment mechanism is connected to the top of the movable net ring 5, which restricts its movement. When the farming space of the fixed net ring 4 needs to be expanded, the adjustment mechanism controls the movable net ring 5 to move downwards, thus expanding the farming space. When the farming space of the fixed net ring 4 needs to be reduced, the adjustment mechanism drags the movable net ring 5 upwards, thus reducing the farming space. This facilitates the partitioned farming of fish.

[0025] In this invention, the water inlet 1 is located at the top of the outer pool body 3, which facilitates the replacement of the aquaculture water in the outer pool body 3.

[0028] In this embodiment 2, the annular support A6 is set between the two support rods 19, and four mounting sleeves 7 are provided, which are arranged around the annular support A6. At least one annular support B8 is provided, which is located inside the outer pool body 3 and connected to all the mounting sleeves 7. The first isolation net 9 is arranged around the annular support A6 and the annular support B8, thereby preventing fish from swimming out and facilitating the partitioned breeding of fish. When using this utility model, the annular support A6 can be selected according to the needs.

[0029] Example 3. (As shown) Figure 1-6 As shown, the present invention provides a factory-produced multi-layer circular breeding pool, including an outer pool body 3 with an inlet 1, a fixing mechanism located on the top of the outer pool body 3, a fixed net ring 4 located on the fixing mechanism and inside the outer pool body 3, a movable net ring 5 slidably located inside the fixed net ring 4, and an adjustment mechanism located on the fixing mechanism for adjusting the position of the movable net ring 5.

[0030] The fixed net ring 4 includes an annular support A6 located at the bottom of the fixed mechanism, several mounting sleeves 7 arranged around the annular support A6, several annular supports B8 located inside the outer pool body 3 and connected to all mounting sleeves 7, and a first isolation net 9 arranged around the annular support B8; the movable net ring 5 is slidably installed on the mounting sleeves 7.

[0031] The movable mesh ring 5 includes a sliding rod 10 slidably disposed within the mounting sleeve 7, an annular bracket C11 connected to all the sliding rods 10, and a second isolation net 12 disposed on the inner wall of the annular bracket C11; the sliding rods 10 are connected to the adjustment mechanism.

[0032] In this embodiment 3, the sliding rod 10 is slidably installed inside the mounting sleeve 7, and one end of the sliding rod 10 is connected to the pull rope 18. Multiple annular brackets C11 are provided, and each annular bracket C11 is connected to all the sliding rods 10. The second isolation net 12 is installed on the annular bracket C11. The annular bracket C11 facilitates the installation of the second isolation net 12, thereby facilitating the partitioned breeding of fish. In use, under the weight of the sliding rod 10, the annular bracket C11, and the second isolation net 12, the sliding rod 10 slides along the mounting sleeve 7, and the movement distance of the sliding rod 10 can be limited by the pull rope 18, thereby adjusting the breeding space of the fixed net ring 4, so that the breeding space of the fixed net ring 4 can be adjusted according to the size of the fish.

[0033] Example 4. (As shown) Figure 1-6As shown, the present invention provides a factory-produced multi-layer circular breeding pool, including an outer pool body 3 with an inlet 1, a fixing mechanism located on the top of the outer pool body 3, a fixed net ring 4 located on the fixing mechanism and inside the outer pool body 3, a movable net ring 5 slidably located inside the fixed net ring 4, and an adjustment mechanism located on the fixing mechanism for adjusting the position of the movable net ring 5.

[0034] The fixed net ring 4 includes an annular support A6 located at the bottom of the fixed mechanism, several mounting sleeves 7 arranged around the annular support A6, several annular supports B8 located inside the outer pool body 3 and connected to all mounting sleeves 7, and a first isolation net 9 arranged around the annular support B8; the movable net ring 5 is slidably installed on the mounting sleeves 7.

[0035] The movable mesh ring 5 includes a sliding rod 10 slidably disposed within the mounting sleeve 7, an annular bracket C11 connected to all the sliding rods 10, and a second isolation net 12 disposed on the inner wall of the annular bracket C11; the sliding rods 10 are connected to the adjustment mechanism.

The limiting block 14 is slidably installed in the limiting groove 13 and slides in the length direction of the limiting groove 13; the annular bracket C11 is installed on the limiting block 14.

[0037] In this embodiment 4, the side wall of the mounting sleeve 7 is provided with a limiting groove 13, and the sliding rod 10 is provided with a limiting block 14 that is adapted to the limiting groove 13. By the cooperation of the limiting groove 13 and the limiting block 14, the movement direction of the sliding rod 10 can be restricted, and the sliding rod 10 can also be prevented from slipping off the bottom of the mounting sleeve 7.

[0038] The limiting block 14 and the annular bracket C11 of this utility model are installed on the sliding rod 10 by screws. The sliding rod 10, the limiting block 14 and the annular bracket C11 are provided with mutually aligned screw holes. The screw holes are threaded into the three screw holes, which facilitates the installation of the annular bracket C11.

[0039] Example 5. (As shown) Figure 1-6 As shown, the present invention provides a factory-produced multi-layer circular breeding pool, including an outer pool body 3 with an inlet 1, a fixing mechanism located on the top of the outer pool body 3, a fixed net ring 4 located on the fixing mechanism and inside the outer pool body 3, a movable net ring 5 slidably located inside the fixed net ring 4, and an adjustment mechanism located on the fixing mechanism for adjusting the position of the movable net ring 5.

[0040] The adjustment mechanism includes a pair of mounting seats 15 on the fixed mechanism, a rotating shaft 16 between the two mounting seats 15, a winding mechanism on the rotating shaft 16, and a drive motor 22 on the fixed mechanism and connected to the rotating shaft 16.

[0041] In this embodiment 5, two mounting bases 15 are set on the mounting plate 20, and the rotating shaft 16 is rotatably set between the two mounting bases 15. Specifically, the mounting base 15 is provided with mounting holes, and bearings are provided in the mounting holes. The rotating shaft 16 is installed in the bearings. The winding mechanism is set on the rotating shaft 16 and rotates synchronously with the rotating shaft 16. One end of the winding mechanism is connected to the sliding rod 10. The drive motor 22 is set on the mounting base 15 and connected to the rotating shaft 16. In use, the drive motor 22 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the winding mechanism to rotate synchronously. The winding mechanism drives the sliding rod 10 to slide along the length direction of the mounting sleeve 7. The sliding rod 10 drives the annular bracket C11 to move synchronously. The annular bracket C11 drives the second isolation net 12 to move, thereby adjusting the position between the bottom of the second isolation net 12 and the first isolation net 9, thereby adjusting the breeding space of the first isolation net 9, so that the breeding space of the first isolation net 9 can be adjusted according to the size of the fish.

[0042] The drive motor 22 used in this invention is a waterproof motor.

[0043] Example 6. (As shown) Figure 1-6 As shown, the present invention provides a factory-produced multi-layer circular breeding pool, including an outer pool body 3 with an inlet 1, a fixing mechanism located on the top of the outer pool body 3, a fixed net ring 4 located on the fixing mechanism and inside the outer pool body 3, a movable net ring 5 slidably located inside the fixed net ring 4, and an adjustment mechanism located on the fixing mechanism for adjusting the position of the movable net ring 5.

[0044] The adjustment mechanism includes a pair of mounting seats 15 on the fixed mechanism, a rotating shaft 16 between the two mounting seats 15, a winding mechanism on the rotating shaft 16, and a drive motor 22 on the fixed mechanism and connected to the rotating shaft 16.

[0045] The winding mechanism includes two winding reels 17 mounted on the rotating shaft 16 and rotating synchronously with the rotating shaft 16, and a pull rope 18 with one end connected to the winding reel 17 and the other end connected to the movable wire mesh 5.

[0046] In this embodiment 6, two winding reels 17 are provided, and the two winding reels 17 are located directly above the mounting sleeve 7. One end of the pull rope 18 is connected to the winding reel 17, and the other end is connected to the sliding rod 10. In use, since the winding reel 17 rotates synchronously with the rotating shaft 16, the winding reel 17 can wind up or unwind the pull rope 18. When the pull rope 18 is unwinding, the sliding rod 10, the annular bracket C11, and the second isolation net 12 will automatically fall under the action of gravity, thereby adjusting the distance between the second isolation net 12 and the first isolation net 9, thereby increasing the breeding space of the first isolation net 9. Similarly, when the pull rope 18 is winding up, the pull rope 18 will pull the two mirror-arranged sliding rods 10 to slide, causing the sliding rods 10 to move upward. The sliding rods 10 drive the annular bracket C11 and the second isolation net 12 to move synchronously, thereby reducing the breeding space of the first isolation net 9, thus facilitating the adjustment of the breeding space of the first isolation net 9.

[0047] Example 7. (As shown) Figure 1-6 As shown, the present invention provides a factory-produced multi-layer circular breeding pool, including an outer pool body 3 with an inlet 1, a fixing mechanism located on the top of the outer pool body 3, a fixed net ring 4 located on the fixing mechanism and inside the outer pool body 3, a movable net ring 5 slidably located inside the fixed net ring 4, and an adjustment mechanism located on the fixing mechanism for adjusting the position of the movable net ring 5.

[0048] The fixing mechanism includes a pair of support rods 19 located at the top of the outer pool body 3, and a mounting plate 20 located between the two support rods 19. The adjusting mechanism is located on the mounting plate 20, and the fixing net ring 4 is located at the bottom of the two support rods 19.

[0049] In this embodiment 7, the support rod 19 is set on the top of the outer pool body 3, and two mounting plates 20 are provided. The two mounting plates 20 are set between the two support rods 19. The annular bracket A6 is connected to the support rod 19 and the mounting plate 20 respectively. Two mounting seats 15 are respectively set on the two mounting plates 20. The drive motor 22 is installed on one of the mounting plates 20. The support rod 19 can facilitate the installation of the fixed net ring 4 and the adjustment mechanism, and at the same time ensures that the moving net ring 5 will not contact the bottom of the outer pool body 3 after installation, so that the water in the outer pool body 3 can flow.

[0050] Example 8. (As shown) Figure 1-6 As shown, the present invention provides a factory-produced multi-layer circular breeding pool, including an outer pool body 3 with an inlet 1, a fixing mechanism located on the top of the outer pool body 3, a fixed net ring 4 located on the fixing mechanism and inside the outer pool body 3, a movable net ring 5 slidably located inside the fixed net ring 4, and an adjustment mechanism located on the fixing mechanism for adjusting the position of the movable net ring 5.

[0051] The bottom of the outer pool body 3 has a conical structure, and its bottom is equipped with a sewage pipe 21 that connects to the external sewage discharge mechanism.

[0052] In this embodiment 8, the bottom of the outer pool 3 has a conical structure. The conical structure facilitates the discharge of dirt and aquaculture water from the outer pool 3 through the drain pipe 21. Furthermore, the drain pipe 21, in conjunction with the inlet 1, facilitates the flow and replacement of aquaculture water in the outer pool 3.

[0053] The first isolation net 9 and the second isolation net 12 of this utility model are made of nylon or polyethylene. The mesh size of the first isolation net 9 and the second isolation net 12 can be customized according to the size of the farmed fish.

[0054] The pull rope 18 of this utility model is a steel wire rope.

[0055] Working principle: In use, the support rod 19 is bolted to the top of the outer pool body 3, and the annular bracket A6 is fixed between the two support rods 19. The sliding rod 10 is installed inside the mounting sleeve 7, and the top of the sliding rod 10 is connected to the pull rope 18. When the pull rope 18 is released, the sliding rod 10, the annular bracket C11, and the second isolation net 12 cause the sliding rod 10 to slide along the mounting sleeve 7 until the sliding rod 10 straightens the pull rope 18. When it is necessary to adjust the breeding space of the first isolation net 9, the drive motor 22 is started. The drive motor 22 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the winding reel 17 to rotate synchronously, so that the winding reel 17 can wind up or release the pull rope 18. When the pull rope 18 is released, the sliding rod 10, the annular bracket C11, and the second isolation net 12 will automatically fall under the action of gravity, thereby adjusting the distance between the second isolation net 12 and the first isolation net 9, thus increasing the breeding space of the first isolation net 9. Similarly, when the pull rope 18 is rolled up, the pull rope 18 will pull the two mirror-set sliding rods 10 to slide, causing the sliding rods 10 to move upward. The sliding rods 10 drive the annular bracket C11 and the second isolation net 12 to move synchronously, thereby reducing the breeding space of the first isolation net 9. Thus, when the first isolation net 9 is used for zoned breeding, the breeding space of the first isolation net 9 can be adjusted according to the size of the fish, which facilitates the zoned breeding of fish. When it is not necessary to raise fish together, the support rod 19 can be removed from the top of the outer pool body 3 to facilitate fish farming.

[0056] The drive motor 22 used in this invention is existing technology and can be purchased and used directly on the market. Therefore, the structure, principle and circuit of the drive motor 22 will not be described in detail here.
