Detailed Implementation

[0025] 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.

[0026] Reference Figures 1-3 An embodiment of this utility model provides an aquaculture filtration device, comprising a first outer shell 1, a motor 2 fixedly connected inside the first outer shell 1, a crankshaft 3 connected to the output end of the motor 2, a first bevel gear 4 fixedly connected to the outer wall of the crankshaft 3, the outer wall of the crankshaft 3 being rotatably connected inside the first outer shell 1, a second bevel gear 5 meshing with the tooth end of the first bevel gear 4, a threaded column 6 fixedly connected to the upper surface of the second bevel gear 5, a first sliding block 7 threadedly connected to the outer wall of the threaded column 6, a fixed plate 8 fixedly connected to the outer wall of the first sliding block 7, a first baffle 10 fixedly connected to the upper surface of the fixed plate 8, a slide rail 9 slidably connected to the outer wall of the fixed plate 8, a second baffle 11 fixedly connected to the lower surface of the slide rail 9, and a limit assembly provided on the outer wall of the crankshaft 3 to prevent the device from suddenly descending. The limit assembly includes a ratchet 13, the ratchet 13 being fixedly connected to the outer wall of the crankshaft 3, and ratchet teeth 14 being provided at the tooth end of the ratchet 13, the outer wall of the ratchet teeth 14 being rotatably connected inside the first outer shell 1.

[0027] Specifically, the output end of motor 2 is used to drive crankshaft 3 to rotate. When crankshaft 3 rotates, it drives the tooth end of first bevel gear 4 to rotate at the tooth end of second bevel gear 5. When the tooth end of first bevel gear 4 rotates at the tooth end of second bevel gear 5, it drives the outer wall of threaded column 6 to slide inside first sliding block 7. When first sliding block 7 slides, it drives the outer wall of fixed plate 8 to slide inside slide rail 9. When the outer wall of fixed plate 8 slides inside slide rail 9, it drives the upper surface of fixed plate 8 to drive the lower surface of first baffle 10. The lifting function allows the lower surface of the slide rail 9 to be fixed inside the second baffle 11, enabling the outer wall of the first bevel gear 4 to rotate inside the second baffle 11. When the crankshaft 3 rotates, it drives the tooth end of the ratchet 13 to rotate at the tooth end of the ratchet 14. When the tooth end of the ratchet 13 rotates at the tooth end of the ratchet 14, it drives the outer wall of the ratchet 14 to rotate inside the first housing 1. This allows the first baffle 10 to be lifted and lowered while preventing sudden descent, effectively preventing the filter device from accidentally sliding down or rising due to water flow impact, equipment vibration, or other factors.

[0028] Reference Figures 4-6 The first outer shell 1 has a rotating groove 12 inside. The outer wall of the crankshaft 3 is rotatably connected to the inside of the first outer shell 1 through the rotating groove 12. The outer wall of the first baffle 10 is slidably connected to the inside of the first outer shell 1. The inner wall of the second baffle 11 is rotatably connected to the outer wall of the second bevel gear 5. The outer wall of the second baffle 11 is fixedly connected to the inside of the first outer shell 1. The upper surface of the first baffle 10 is fixedly connected to a water tank 15. The outer wall of the water tank 15 is slidably connected to the inside of the first outer shell 1. A filter plate 16 is provided inside the water tank 15.

[0029] Specifically, when the interior of the water tank 15 is fixed to the outer wall of the filter plate 16, it can achieve the function of filtering impurities in the water.

[0030] Reference Figure 6 The water tank 15 has a second outer shell 17 inside. The outer wall of the second outer shell 17 is located inside the filter plate 16. The second outer shell 17 is threadedly connected to a threaded block 18. A handle 19 is fixedly connected to the upper surface of the threaded block 18. A compression assembly is provided on the lower surface of the threaded block 18. The compression assembly includes a spring 20. The top end of the spring 20 is located on the lower surface of the threaded block 18. A second sliding block 21 is provided at the bottom end of the spring 20. A ball 22 slides on the outer wall of the second sliding block 21. The outer wall of the ball 22 slides inside the second outer shell 17. The outer wall of the spring 20 is compressed inside the second outer shell 17. The outer wall of the second sliding block 21 slides inside the second outer shell 17.

[0031] Specifically, when the handle 19 is rotated, it can cause the outer wall of the threaded block 18 to rotate inside the second housing 17. When the outer wall of the threaded block 18 rotates inside the second housing 17, it can cause the lower surface of the threaded block 18 to be fixed at the top of the spring 20. When the threaded block 18 rotates, it can cause the bottom end of the spring 20 to compress the upper surface of the second sliding block 21. When the bottom end of the spring 20 compresses the upper surface of the second sliding block 21, it can cause the outer wall of the second sliding block 21 to slide along the outer wall of the ball 22. When the second sliding block 21 slides, it can cause the outer wall of the ball 22 to slide inside the second housing 17. When the outer wall of the second housing 17 is fixed inside the water tank 15, it can cause the outer wall of the second housing 17 to be fixed inside the filter plate 16, ultimately achieving the effect of replacing the filter plate 16 and ensuring that the filtration system is always in a state of high-efficiency operation.

[0032] Working principle: When the device is needed, the output end of motor 2 drives crankshaft 3 to rotate. When the outer wall of crankshaft 3 drives the interior of first bevel gear 4 to rotate, the tooth end of first bevel gear 4 will rotate at the tooth end of second bevel gear 5. When the upper surface of second bevel gear 5 is fixed to the lower surface of threaded column 6, the outer wall of second bevel gear 5 will rotate inside second baffle 11. When the outer wall of threaded column 6 drives the interior of first sliding block 7 to slide, the outer wall of first sliding block 7 will drive the outer wall of fixed plate 8 to slide. When the outer wall of fixed plate 8 slides inside slide rail 9, the lower surface of slide rail 9 will be fixed to the upper surface of second baffle 11. When the upper surface of fixed plate 8 is fixed to the lower surface of first baffle 10, the outer wall of first baffle 10 will rise and fall inside first housing 1. When the outer wall of crankshaft 3 drives the interior of ratchet 13 to rotate, the tooth end of ratchet 13 will rotate at the tooth end of ratchet 14. The rotation, via the outer wall of the ratchet 14, inside the first housing 1, ultimately achieves the effect of raising and lowering the first baffle 10 and preventing sudden descent. By rotating the handle 19, the threaded block 18 is driven to rotate. When the threaded block 18 rotates inside the second housing 17 via the outer wall of the threaded block 18, the lower surface of the threaded block 18 is fixed at the top of the spring 20. When the bottom end of the spring 20 compresses the upper surface of the second sliding block 21, the outer wall of the second sliding block 21 drives the outer wall of the ball 22 to slide. When the outer wall of the second housing 17 is fixed inside the water tank 15, the outer wall of the second housing 17 is fixed inside the filter plate 16, ultimately achieving the effect of replacing the filter plate 16. This not only effectively prevents the filter device from accidentally sliding down or rising due to water flow impact, equipment vibration, etc., ensuring that the filter device is always in the set position, but also allows for regular replacement of the filter device, ensuring that the filtration system is always in a state of high efficiency.
