[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] In order to increase the yield of aquaculture, in addition to using ponds or net cages, artificial fish ponds can be set up on land or inside buildings to enrich the breeding scene and increase the yield. However, as the demand for production increases, the number of artificial fish ponds increases, and the corresponding land area also needs to be increased.

[0036] In the prior art, the purpose of improving the area utilization rate is achieved by setting up a multi-level fish pond in a building. This multi-level fish pond has multiple artificial fish ponds fixed in the vertical space, and stairs are set around the multi-level fish pond to meet the needs of daily use and maintenance. However, the distance between the multiple artificial fish ponds cannot be adjusted, which cannot meet the needs of using artificial fish ponds of various sizes. In addition, the building needs to have a high floor height to set up the multi-level fish pond, which increases the investment cost.

[0037] In response, this embodiment provides a multi-layer aquaculture device, which can also improve the area utilization rate and solve the above-mentioned problems.

[0038] like Figure 1 , Figure 7 and Figure 8 As shown, the multi-layer aquaculture device includes a support frame 1, a first lifting unit, a bottom water tank 31, a top water tank 33, and two lifting components. The support frame 1 is fixedly installed on the ground and includes a base 11 and a top support frame 13. A column 111 is fixedly installed on the base 11. The first lifting unit includes a sleeve 251 and a threaded lifting rod 252. The inner wall of the sleeve 251 is threaded, and the threaded lifting rod 252 is threadedly connected to the inner wall of the sleeve 251. The threaded lifting rod 252 is fixedly connected to the top support frame 13. Both lifting components are fixedly connected to the column 111. The sleeve 251 is rotatably mounted on one of the lifting components, and one of the lifting components is configured to drive the sleeve 251 to rotate. The bottom water tank 31 is fixedly connected to the base 11, and the top water tank 33 is fixedly connected to the top support frame 13. The sleeve 251 is rotatably mounted on one of the lifting components, and one of the lifting components drives the sleeve 251 to rotate. The threaded lifting rod 252 is screwed to the sleeve 251. When the sleeve 251 rotates in different directions, the thread on the inner wall of the sleeve 251 drives the threaded lifting rod 252 to rise or fall, thereby driving the top bracket 13 to rise or fall, realizing the rise and fall of the top water tank 33. When different specifications of bottom water tanks 31 are required, the use of different specifications of bottom water tanks 31 can be met by raising and lowering the top bracket 13, while avoiding occupying too much vertical space, reducing the building's floor height, and thus reducing investment costs.

[0039] Furthermore, such as Figure 1 , Figures 7-10As shown, to improve the space utilization of the multi-layer aquaculture device, the device also includes a middle-layer water tank 32 and a second lifting actuator. The support 1 also includes a middle-layer bracket 12. The second lifting actuator includes a threaded shaft 26, which is threadedly connected to the middle-layer bracket 12. The threaded shaft 26 is rotatably mounted on another lifting assembly, which is configured to drive the threaded shaft 26 to rotate. The middle-layer water tank 32 is fixedly connected to the middle-layer bracket 12. When the other lifting assembly drives the threaded shaft 26 to rotate, the middle-layer bracket 12 is threadedly connected to the threaded shaft 26, and the middle-layer bracket 12 screws in or out relative to the threaded shaft 26, thereby raising or lowering the middle-layer bracket 12 and the middle-layer water tank 32. The inclusion of the middle-layer bracket 12 and the second lifting unit further improves the space utilization of the multi-layer aquaculture device and further reduces investment costs. Those skilled in the art can, based on actual needs, add multiple middle-layer brackets 12 and second lifting actuators, and correspondingly add a number of lifting assemblies, to further improve space utilization.

[0040] Specifically, the support frame 1 includes a base 11, a middle-layer bracket 12, and a top-layer bracket 13. Multiple uprights 111 are fixedly mounted on the base 11, and these uprights 111 are evenly distributed on the base 11. In this embodiment, the number of uprights 111 can be 4, 5, 6, 7, 8, 9, 10, 11, or 12, preferably 6, to meet usage requirements. The top-layer bracket 13 includes multiple top-layer longitudinal beams 131 and multiple top-layer transverse beams 132. The multiple top-layer longitudinal beams 131 are arranged parallel to each other, and the distance between two adjacent top-layer longitudinal beams 131 is equal. Multiple top-layer transverse beams 132 are fixedly connected to the top-layer longitudinal beams 131, and the distance between two adjacent top-layer transverse beams 132 is equal. The middle-layer bracket 12 includes multiple middle-layer longitudinal beams 121 and multiple middle-layer transverse beams (not shown in the figure). The multiple middle-layer longitudinal beams 121 are arranged parallel to each other, and the distance between two adjacent middle-layer longitudinal beams 121 is equal. Multiple intermediate crossbeams are fixedly connected to intermediate longitudinal beams 121.

[0042] Optionally, the number of lifting components can be 2, 3, 4, 5, or 6. In this embodiment, the number of lifting components is preferably two. One lifting component realizes the lifting and lowering of the top-level bracket 13 and the top-level water tank 33 through a first lifting actuator.

Correspondingly, the number of the first lifting unit and / or the second lifting unit is preferably six. Those skilled in the art can change the number of reversing box assemblies 23 and the number of transfer box assemblies 24 according to actual needs, such as setting the number of transfer boxes to two, six, or eight, and the number of reversing boxes to four.

[0044] Furthermore, the drive housing assembly 22 includes a drive housing 221, a drive input shaft 222, a drive output shaft 223, and two bevel gears 28.

[0045] Furthermore, the reversing gearbox assembly 23 includes a reversing gearbox body 231, a reversing input shaft 232, a reversing output shaft 233, and two bevel gears 28. The reversing gearbox body 231 is fixedly connected to the column 111.

In this embodiment, to simplify the structural complexity, a connecting shaft 271 is also provided between the reversing input shaft 232 and the drive output shaft 223. The two ends of the connecting shaft 271 are connected to the reversing input shaft 232 and the drive output shaft 223 respectively through a coupling 272.

The reversing output shaft 233 and the reversing gearbox body 231 are rotatably connected, and a bearing 29 is provided between the reversing output shaft 233 and the reversing gearbox body 231. A bevel gear 28 is fixedly connected to the reversing output shaft 233. The connection between the bevel gear 28 and the reversing output shaft 233 can be a key connection, an interference fit, or an integral molding connection, preferably a key connection. A bevel gear 28 is fixedly connected to the reversing input shaft 232.

A bearing 29 is provided between the sleeve 251 and the reversing housing 231, and a bearing 29 is provided between the threaded shaft 26 and the reversing housing 231. The reversing housing 231 can restrict the movement of the sleeve 251 and the threaded shaft 26 along its axis.

[0046] Furthermore, the number of reversing gearbox assemblies 23 is preferably two, and the two reversing input shafts 232 of the two reversing gearbox assemblies 23 are respectively connected to the two ends of the drive output shaft 223, thereby improving the structural symmetry of the lifting assembly.

[0047] Specifically, the principle by which the reversing gearbox assembly 23 achieves the lifting and lowering of the top-level bracket 13 is as follows: The output shaft of the drive motor rotates, which drives the drive input shaft 222 to rotate through the coupling 272. The bevel gear 28 on the drive input shaft 222 meshes with the bevel gear 28 on the drive output shaft 223 and drives the drive output shaft 223 to rotate. The drive output shaft 223 drives the reversing input shaft 232 to rotate via the coupling 272 and the connecting shaft 271. The bevel gear 28 on the reversing input shaft 232 meshes with the bevel gear 28 on the reversing output shaft 233, driving the reversing output shaft 233 to rotate. Simultaneously, the worm gear on the reversing input shaft 232 meshes with the worm wheel on the sleeve 251, driving the sleeve 251 to rotate. The reversing housing 231 restricts the movement of the sleeve 251 along its axis. The thread on the inner wall of the sleeve 251 drives the threaded lifting rod 252 to move up or down. The threaded lifting rod 252 is fixedly connected to the top bracket 13, thereby realizing the raising or lowering of the top bracket 13. In this embodiment, the reversing input shaft 232 is set as a worm shaft, and a worm wheel is set outside the sleeve 251 to mesh with the worm shaft. While satisfying the transmission of motion, it can also reduce speed and increase torque without the need for an additional speed reduction device, simplifying the complexity of the overall structure. Furthermore, since no additional speed reduction device is set in the transmission route, the rotational speed of the reversing input shaft 232 and the rotational speed of the intermediate input shaft 242 are guaranteed to be equal, which provides a basis for the connection points of the top bracket 13 and the multiple threaded lifting rods 252 to rise or fall synchronously.

[0048] Specifically, the reversing gearbox assembly 23 achieves the lifting and lowering principle of the middle shelf bracket 12 as follows: The output shaft of the drive motor rotates, driving the drive input shaft 222 to rotate via the coupling 272. The bevel gear 28 on the drive input shaft 222 meshes with the bevel gear 28 on the drive output shaft 223, driving the drive output shaft 223 to rotate. The drive output shaft 223 drives the reversing input shaft 232 to rotate via the coupling 272 and the connecting shaft 271. The bevel gear 28 on the reversing input shaft 232 meshes with the bevel gear 28 on the reversing output shaft 233, driving the reversing output shaft 233 to rotate. At the same time, the worm gear on the reversing input shaft 232 meshes with the worm wheel on the threaded shaft 26, driving the threaded shaft 26 to rotate. The reversing gearbox 231 restricts the movement of the threaded shaft 26 along its axis. The threaded shaft 26 is threadedly connected to the middle shelf bracket 12, thereby realizing the raising or lowering of the middle shelf bracket 12. In this embodiment, the reversing input shaft 232 is configured as a worm shaft, and a worm wheel is provided outside the threaded shaft 26 to mesh with the worm shaft. While satisfying the transmission of motion, it can also reduce speed and increase torque without the need for an additional speed reduction device, simplifying the overall structural complexity. Furthermore, since no additional speed reduction device is provided in the transmission route, the rotational speed of the reversing input shaft 232 and the intermediate input shaft 242 are ensured to be equal, providing a basis for the synchronous rise or fall of the connection points between the middle bracket 12 and the multiple threaded shafts 26.

[0049] Furthermore, the transfer box assembly 24 includes a transfer box body 241, a transfer input shaft 242, a transfer output shaft 243, and two bevel gears 28. The transfer box body 241 is fixedly connected to the column 111. The transfer input shaft 242 and the reversing output shaft 233 are connected by a drive mechanism, which can be via a coupling 272 or a gearbox. In this embodiment, to simplify the structural complexity, a connecting shaft 271 is also provided between the transfer input shaft 242 and the reversing output shaft 233. The two ends of the connecting shaft 271 are connected to the transfer input shaft 242 and the reversing output shaft 233 respectively via a coupling 272. The transfer input shaft 242 is rotatably connected to the transfer box body 241, and a bearing 29 is provided between the transfer input shaft 242 and the transfer box body 241. The transfer output shaft 243 is rotatably connected to the transfer box body 241, and a bearing 29 is provided between the transfer output shaft 243 and the transfer box body 241.

A bevel gear 28 is fixedly connected to the transfer input shaft 242. The connection between the bevel gear 28 and the transfer input shaft 242 can be a key connection, an interference fit, or an integral molding connection, preferably a key connection. The two bevel gears 28 connected to the transfer input shaft 242 and the transfer output shaft 243 are bevel gears of the same specification, and the two bevel gears 28 mesh with each other. The angle between the shafts of the two bevel gears 28 is preferably 90 degrees. At least one end of the transfer input shaft 242 extends out of the transfer housing 241. In this embodiment, to strengthen the support for the top layer bracket 13 or the middle layer bracket 12, it is preferable that both ends of the transfer input shaft 242 extend out of the transfer housing 241. In this embodiment, two transfer box assemblies 24 symmetrically arranged on the top bracket 13 or the bottom bracket form a group. Those skilled in the art can set multiple groups of transfer box assemblies 24 according to actual needs. Adjacent groups of transfer box assemblies 24 are connected by a transmission to strengthen the support for the top bracket 13 or the middle bracket 12. The transfer output shaft 243 is a worm shaft. The worm shaft can be manufactured by turning or grinding, and its manufacturing process is a mature existing technology in this field, which will not be elaborated here. The worm of the transfer output shaft 243 has the same specifications and parameters as the worm of the reversing input shaft 232, such as the number of threads, module, number of teeth, and lead. Worm wheels are fixedly installed on both the sleeve 251 and the threaded shaft 26. The connection between the worm wheel and the sleeve 251 can be a key connection or an interference fit, preferably a key connection. The connection between the worm wheel and the threaded shaft 26 can also be a key connection or an interference fit, preferably a key connection. The worm wheel can mesh with the worm shaft. Both the sleeve 251 and the threaded shaft 26 are rotatably connected to the transfer box 241. A bearing 29 is provided between the sleeve 251 and the transfer box 241, and a bearing 29 is also provided between the threaded shaft 26 and the transfer box 241. Furthermore, the transfer box 241 can restrict the movement of the sleeve 251 and the threaded shaft 26 along its axis.

[0050] Specifically, the principle by which the transfer box assembly 24 achieves the lifting and lowering of the top-level bracket 13 is as follows: The reversing output shaft 233 drives the transfer input shaft 242 to rotate through the coupling 272 and the connecting shaft 271. The bevel gear 28 on the transfer input shaft 242 meshes with the bevel gear 28 on the transfer output shaft 243, driving the transfer output shaft 243 to rotate. At the same time, the worm gear on the transfer output shaft 243 meshes with the worm wheel on the sleeve 251, driving the sleeve 251 to rotate. The transfer box 241 restricts the movement of the sleeve 251 along its axis. The thread on the inner side wall of the sleeve 251 drives the threaded lifting rod 252 to move up or down. The threaded lifting rod 252 is fixedly connected to the top-level bracket 13, thereby realizing the raising or lowering of the top-level bracket 13. In this embodiment, the transfer output shaft 243 is set as a worm shaft, and a worm wheel is set outside the sleeve 251 to mesh with the worm shaft. While fulfilling the requirements for motion transmission, it can also reduce speed and increase torque without the need for an additional speed reduction device, simplifying the overall structural complexity. Furthermore, since the worm gear of the intermediate output shaft 243 and the worm gear of the reversing input shaft 232 have the same specifications, and the reversing box assembly 23 already ensures that the rotational speed of the reversing input shaft 232 is equal to that of the intermediate input shaft 242, the connection points between the top bracket 13 and the multiple threaded lifting rods 252 can rise or fall synchronously. This prevents the top bracket 13 from tilting due to asynchronous movements, which could cause water in the top water tank 33 to overflow or even overturn.

[0051] Specifically, the principle by which the intermediate bracket 12 is raised and lowered by the transfer box assembly 24 is as follows: The reversing output shaft 233 drives the transfer input shaft 242 to rotate through the coupling 272 and the connecting shaft 271. The bevel gear 28 on the transfer input shaft 242 meshes with the bevel gear 28 on the transfer output shaft 243, driving the transfer output shaft 243 to rotate. At the same time, the worm gear on the transfer output shaft 243 meshes with the worm wheel on the threaded shaft 26, driving the threaded shaft 26 to rotate. The transfer box 241 restricts the movement of the threaded shaft 26 along its axis. The threaded shaft 26 is screwed to the intermediate bracket 12, thereby realizing the raising or lowering of the top bracket 13. In this embodiment, the transfer output shaft 243 is set as a worm shaft, and a worm wheel is set on the threaded shaft 26 to mesh with the worm shaft. While satisfying the transmission of motion, it can also reduce speed and increase torque, eliminating the need for an additional speed reduction device and simplifying the complexity of the overall structure. Furthermore, since the worm gear of the intermediate output shaft 243 and the worm gear of the reversing input shaft 232 have the same specifications, and the reversing box assembly 23 has already ensured that the rotational speed of the reversing input shaft 232 and the rotational speed of the intermediate input shaft 242 are equal, the connection points of the top bracket 13 and the multiple threaded lifting rods 252 can rise or fall synchronously, thus avoiding the top bracket 13 from tilting due to asynchronous operation, which could cause water in the top water tank 33 to overflow or even overturn.

[0052] Optionally, to avoid the use environment being too humid and prone to corrosion, the bracket 1, the first lifting actuator, the second lifting actuator, and the two lifting components in this embodiment are all made of stainless steel, plastic, or carbon fiber. Those skilled in the art can also select high-strength steel such as Q235 or Q345 according to the actual engineering requirements, and apply an anti-corrosion coating or galvanize the steel surface to prevent rust.
