[0002] Leeches are annelids of the Hirudinidae family of the order Gnathioviridae, also known as leeches. They have long, flat, and slightly spindle-shaped bodies. The back is often dark green with vertical lines formed by fine yellow-black spots, and the midline of the back is darker; the ventral surface is light yellow with light yellow vertical stripes on each side, mixed with many irregular tea-green spots. They are composed of a certain number of segments, with an oral sucker and a posterior sucker. The dried body of the leech can be used as medicine, which has the effects of breaking blood, dredge menstruation, removing blood stasis and eliminating symptoms. It is mainly used to treat blood stasis, amenorrhea, accumulation of symptoms, injuries from falls, heart and abdominal pain, etc. The nutritional value of leeches is very high, and its main components are protein, polypeptides, trace elements and fat.

[0003] In the process of breeding leeches, there will be various debris in the breeding water, such as a large amount of feces produced by leech seedlings and a large amount of sediment formed by residual bait, as well as various debris from outside the breeding water body that will accumulate in the breeding pond. These residual sediments will rot and stink over time, leading to the enrichment of various harmful factors in the water body. If not handled in time, it will cause the outbreak of leech seedling diseases, and in severe cases, it can cause the death of leech seedlings. Therefore, it is urgent to clean up the dirt in the breeding pond in time and discharge it in time. Traditional sediment cleaning is done by manually holding a sewage suction device, moving left and right at the bottom of the fish box to suck the entire bottom, which wastes labor and is inefficient.

[0004] Therefore, in order to solve such problems, we proposed a sewage discharge device for leech seedling breeding. Utility Model Content

[0022] Reference Figure 1-4The utility model provides an embodiment: a sewage discharge device for leech seedling breeding, comprising a breeding pond 1, wherein a sewage discharge assembly 2 is arranged inside the breeding pond 1, and the residues precipitated at the bottom of the breeding pond 1 are sucked out by the sewage discharge assembly 2 to prevent debris from accumulating in the breeding pond 1, affecting the water quality, and destroying the breeding environment of the leech seedlings. The sewage discharge assembly 2 comprises a column 21 installed on the top of the breeding pond 1, and a driving member 22 is arranged between the columns 21. The driving member 22 comprises a screw rod 221 rotatably connected between adjacent side walls of the column 21, and one end of the screw rod 221 is connected to a motor 222, and the motor 222 is fixedly installed on the column 21. The outer spiral sleeve of the screw rod 221 is connected to a sleeve column 223, and a moving frame 23 is installed on the outer wall of the sleeve column 223, which can drive the moving frame 23 to move. A hydraulic cylinder 24 is fixedly arranged at one end of the inner side of the moving frame 23, and a telescopic rod 25 is connected to the output end of the hydraulic cylinder 24, and a fixed collar 26 is arranged at the end of the telescopic rod 25 away from the hydraulic cylinder 24. A sewage pumping pipe 27 is arranged inside the fixed collar 26, and the fixed collar 26 is slidably arranged inside the movable frame 23. The lower end of the sewage pumping pipe 27 is connected with a sewage suction head 28 for extracting impurities from the water. The upper end of the sewage pumping pipe 27 is connected with a bellows 29. The end of the bellows 29 away from the sewage pumping pipe 27 is provided with a sewage discharge pipe 211. The sewage discharge pipe 211 is installed on the outer wall of the culture pond 1 through a positioning block. The sewage discharge pipe 211 is connected to the bellows 29 through a sewage pump 210. The sewage discharge pipe 211 A collecting box 3 is arranged below the aquaculture pond 1. The motor 222 controls the screw rod 221 to rotate, so that the sleeve column 223 drives the moving frame 23 to move, thereby pushing the sewage suction pipe 27 to move back and forth in the aquaculture pond 1. The hydraulic cylinder 24 controls the telescopic rod 25 to drive the sewage suction pipe 27 to move left and right in the aquaculture pond 1, so that the sewage suction head 28 on the sewage suction pipe 27 extracts the sediment in various ranges at the bottom of the aquaculture pond 1. The sediment enters the collecting box 3 from the outlet of the sewage pipe 211 through the corrugated pipe 29 for centralized treatment.

[0023] A sewage collecting bag 31 is arranged inside the collecting box 3. The sewage collecting bag 31 is made of fiber cloth. A filter plate 32 is arranged below the sewage collecting bag 31. The liquid passes through the sewage collecting bag 31 and then enters the bottom of the collecting box 3 after being filtered by the filter plate 32. Impurities are intercepted inside the sewage collecting bag 31. A water pipe 33 is arranged on the collecting box 3 below the filter plate 32. One end of the water pipe 33 extends through the inside of the breeding pond 1. A water pump 34 is arranged outside the water pipe 33. The filtered water in the collecting box 3 is re-injected into the breeding pond 1 through the water pipe 33 by the water pump 34, so as to avoid a reduction in the amount of water in the breeding pond 1 and affect breeding.

[0024] A slide groove 4 is provided at the top of the side of the breeding pond 1 away from the driving member 22, and a slider 5 is movably provided inside the slide groove 4. The upper end of the slider 5 is fixedly connected to the moving frame 23. When the moving frame 23 moves, the slider 5 moves along the slide groove 4 to limit the moving frame 23, so that the moving frame 23 can move more steadily and smoothly.

[0025] A protective cover 6 is provided on the outside of the sewage suction head 28 to prevent the leech seedlings from being sucked into the sewage suction head 28. The protective cover 6 is sleeved on the lower end of the sewage suction pipe 27. The bottom side of the protective cover 6 is in contact with the bottom of the breeding pond 1. The sewage suction pump 210 is started, and a negative pressure is formed inside the protective cover 6 to discharge the debris inside the protective cover 6. A cleaning brush 7 is provided inside the protective cover 6. When the cleaning brush 7 moves, it brushes up the sediment at the bottom of the breeding pond 1 to make it easier to be sucked.

[0026] The outside of the sewage suction pipe 27 is sleeved with a fixing plate 8, and a spring 9 is arranged on the top of the fixing plate 8. The spring 9 is fixedly connected to the fixing ring 26 through an ear plate. The fixing plate 8 is pushed by the spring 9 to drive the sewage suction pipe 27 downward, so that the bottom of the protective cover 6 always fits the bottom of the breeding pond 1 to avoid gaps that may cause leech seedlings to enter by mistake.

[0027] Working principle: first, fit the protective cover 6 to the bottom of the breeding pond 1 to avoid leech seedlings, start the sewage pump 210, form a negative pressure inside the protective cover 6, and suck out impurities. The motor 222 controls the screw rod 221 to rotate, so that the sleeve column 223 drives the moving frame 23 to move, thereby pushing the sewage pipe 27 to move back and forth in the breeding pond 1. Cooperate with the hydraulic cylinder 24 to control the telescopic rod 25 to drive the sewage pipe 27 to move left and right in the breeding pond 1, so that the sewage suction head 28 on the sewage pipe 27 extracts the sediment in various ranges at the bottom of the breeding pond 1. The sediment enters the sewage collecting bag 31 from the outlet of the sewage pipe 211 through the corrugated pipe 29. The liquid passes through the sewage collecting bag 31 and then enters the bottom of the collecting box 3 after being filtered by the filter plate 32. The impurities are intercepted inside the sewage collecting bag 31, which is convenient for centralized treatment. The filtered water is re-injected into the breeding pond 1 through the water pump 34 and the water pipe 33.
