[0002] Cold-water fish fry require high water quality during the breeding period, including stable water temperature, appropriate dissolved oxygen, low pollution, and good water quality. Therefore, the design of the sewage discharge device needs to effectively remove waste, excess feed, and other organic matter to maintain water cleanliness.

[0003] A search revealed Chinese Patent Publication No. CN213187700U, which discloses a sewage discharge device for a fish farming pond. The device includes a farming pond, a sewage pipe, and a sewage well. One end of the sewage pipe is fixedly connected to one end of the sewage well, and the other end is fixed to the bottom of the farming pond. A first valve is installed on the sewage pipe. The inner bottom wall of the farming pond slopes downwards from the edge to the center, and a baffle is fixedly connected inside the pond. This invention eliminates the need for workers to clean the farming pond, thus improving work efficiency.

[0004] While the aforementioned technologies do not require manual cleaning of the aquaculture ponds, during sewage discharge, a large amount of sedimented fish feces and other impurities will be partially remixed into the upper water, resulting in a significant waste of water and poor sewage discharge efficiency, making them unsuitable for use. Therefore, a sewage discharge device for cold-water fish fry aquaculture is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a wastewater discharge device for cold-water fish fry rearing, comprising a water tank 1, the interior of which can be used to hold cold-water fish fry. A sliding rod 2 is slidably connected to the left side of the inner wall of the water tank 1. The sliding rod 2 can drive a squeezing rod 4 to slide horizontally and vertically. The lower part of the sliding rod 2 is fixedly connected to the squeezing rod 4. The squeezing rod 4 can slide to the right and down so that the closing plate 9 can close the square trough 14. This allows the wastewater and impurities in the square trough 14 to be discharged without mixing with the upper clear water, resulting in better wastewater discharge and reducing wastewater accumulation. With reduced wear and tear, a positioning rod 5 is slidably connected to the middle of the squeezing rod 4. The positioning rod 5 consists of a middle vertical plate and two horizontal bars at both ends. The horizontal bars can keep the vertical plate vertical and can also drive the vertical plate to slide horizontally to prevent it from obstructing the sliding rod 2 from sliding. The two ends of the positioning rod 5 are slidably connected to the inner wall of the pool 1. The pool 1 can keep the positioning rod 5 horizontal. A baffle 6 is fixedly connected to the left side of the sliding rod 2. The baffle 6 is slidably connected to the left side of the inner wall of the pool 1. The baffle 6 is restricted by the pool 1 to slide horizontally within a fixed distance.

[0034] Reference Figure 2 , Figure 5 and Figure 6 A locking block 12 is elastically connected to the upper left end of pool 1 via a spring 13. The locking block 12 prevents the sliding rod 2 from sliding horizontally, ensuring stability. The left side of the locking block 12 is slidably connected to the inner left wall of the sliding rod 2. One end of the spring 13 is fixedly connected to the right side of the locking block 12. The spring 13 is pressed against the inner left wall of pool 1, keeping the locking block 12 in a fixed position inside the left end of the sliding rod 2. The other end of the spring 13 is fixedly connected to the upper left end of pool 1. The lower part of the squeezing rod 4 contacts a sealing plate 9. The sealing plate 9 can rotate to close the square groove 14, preventing impurities from spreading out. The lower part of the sealing plate 9 is hinged to the square groove 14, which can... To hold sediment, the outer side of the square trough 14 is fixedly connected to the bottom of the inner wall of the pool 1. The upper left side of the square trough 14 is elastically connected to the left side of the sealing plate 9 by a spring 10. The spring 10 pulls the sealing plate 9 to keep it vertical, so that fish feces and other impurities can settle into the inside of the square trough 14. One end of the spring 10 is fixedly connected to the top left side of the square trough 14. The spring 10 is pulled by the upper side of the square trough 14 to keep the sealing plate 9 in a pulling state. The other end of the spring 10 is fixedly connected to the left side of the sealing plate 9. A screen 8 is fixedly connected to the front of the square trough 14. The screen 8 can prevent fish fry from flowing out with the sewage and reduce losses. A sewage discharge assembly is slidably connected to the lower part of the pool 1.

[0035] Reference Figure 1 , Figure 2 and Figure 4The sewage discharge assembly includes a sliding plate 7, which can close the lower right end of the pool 1 to prevent water from flowing out. The outer side of the sliding plate 7 is slidably connected to the lower right end of the pool 1. The pool 1 restricts the sliding plate 7 to slide vertically within a fixed distance. Magnets 11 are fixedly connected to both the upper and lower parts of the sliding plate 7. The magnets 11 attract and keep the sliding plate 7 fixed, so that the screen 8 remains fixed and does not slide down when discharging sewage. The outer end of the magnet 11 is in contact with the lower right end of the pool 1. A connecting rod 3 is fixedly connected to the right end of the sliding plate 7. The connecting rod 3 can drive multiple sets of sliding plates 7 to slide up and down at the same time, making the operation more convenient.

[0036] Working principle: By sliding outward, the locking block 12 can slide out of the left end of the sliding rod 2, squeezing the spring 13. Then, the sliding rod 2 slides to the right. The sliding rod 2 and the baffle 6 slide to the right until the right part of the baffle 6 contacts the inner wall of the left end of the pool 1 and stops sliding. At this time, the sliding rod 2 drives the pressing rod 4 to slide. The pressing rod 4 squeezes the closing plate 9 to rotate to a non-vertical state. Then, the sliding rod 2 slides down, driving the pressing rod 4 to slide down. The pressing rod 4 slides down and squeezes the closing plate 9 to a horizontal state, so that the upper end of the square groove 14 is closed. At this time, the sliding rod 2 is fixed and no longer slides down. Then, the connecting rod 3 slides up, driving the slide plate 7 to slide up. The slide plate 7 slides up, driving the magnet 11 to slide up. The magnet 11 slides up. When the upper end face contacts the inner wall of the pool 1, the slide plate 7 is kept fixed and no longer slides. At this time, impurities are discharged with the bottom water, and the fish fry are blocked by the screen 8 and will not slide out. After the sewage is discharged, the slide plate 7 can be lowered so that it and the connecting rod 3 can slide down to the lower end magnet 11 and contact the inner wall of the pool 1. It can be kept fixed. Then the sliding rod 2 and the squeezing rod 4 are slid up until they are restricted by the positioning rod 5 and no longer slide up. The sliding rod 2 is slid horizontally. The sliding rod 2 drives the positioning rod 5 and the squeezing rod 4 to slide horizontally back to their original positions. The locking block 12 is released so that the spring 13 squeezes the locking block 12 into the front square groove 14 of the sliding rod 2 to keep the sliding rod 2 fixed. During this process, the closing plate 9 is pulled back to the vertical position by the spring 2 10.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
