Description

Technical Field

[0001] This utility model relates to the field of cleaning and purification technology, and in particular to a cleaning and purification device for a recirculating water fish fry rearing pond. Background Technology

[0002] Recirculating aquaculture ponds are key facilities for raising fish fry in aquaculture. Through a water circulation system, they dynamically renew the pond water and maintain water quality, providing a suitable growth environment for the fry. Their core function is to remove pollutants such as uneaten feed and feces from the water through filtration and aeration, maintaining clean water and sufficient dissolved oxygen, thereby improving the survival rate and growth rate of the fry. These ponds are widely used in aquaculture seed breeding bases, research institutions, and large-scale aquaculture enterprises, and are a crucial link in ensuring the quality of seedlings in the aquaculture industry chain.

[0003] Existing purification devices in recirculating aquaculture fry rearing ponds mostly rely on fixed-installation filtration components (such as filter screens and biological filters), which can only purify the water in a fixed area. Since fry rearing ponds are typically large and the water flow is unevenly distributed due to natural convection, fixed-location filtration structures cannot quickly cover the entire pond area. This leads to pollutant accumulation in localized areas exceeding the purification rate, especially in areas where uneaten feed is concentrated or where fry congregate, resulting in water quality deterioration. Therefore, a cleaning and purification device for recirculating aquaculture fry rearing ponds is proposed. Utility Model Content

[0029] Working Principle: In the idle area of ​​this device, all the aforementioned components, specifically the structural parts, are connected. The specific connection methods should refer to the working principle described below, where the components are connected sequentially. The detailed connection methods are well-known in the field. The following mainly introduces the working principle and process, without further explanation. When using this device, the working range is first adjusted via the lateral movement mechanism: the first motor 3 on the fixed plate 4 drives the first threaded screw 5 to rotate, causing the first slider 7 to slide along the first groove 2, thereby causing the side plate 6 to move laterally along the cultivation tank 1, achieving left-right position coverage. Simultaneously, the height adjustment mechanism is activated: the second motor 11 on the side plate 6 drives the second threaded screw 10 to rotate, causing the second slider 9 to slide up and down along the second groove 12, driving the lifting plate 8 to adjust the height, allowing the tank 13 to move closer to or further away from the water surface to adapt to purification needs at different water depths. The longitudinal movement mechanism operates synchronously: the third motor 19 on the lifting plate 8 drives the third threaded screw 17 to rotate, the third slider 18 slides along the third slide groove 16, driving the moving block 15 and the top box 13 to move longitudinally along the transverse groove 14, achieving positional coverage in the front and rear directions. The three mechanisms work together to allow the box 13 to reach any area within the cultivation pond 1. After the liquid extraction mechanism is started, the liquid extraction pump 20 extracts pond water from the cultivation pond 1 through the liquid extraction pipe 37. The protective cover 21 prevents the fish fry from being sucked in. The pond water enters the top box 24 through the liquid extraction pipe 37 and undergoes preliminary filtration through the filter cover 38 to intercept large particles of impurities. The fourth motor 22 drives the rotating shaft 23 to rotate. The water in the top box 24 enters the hollow rotating shaft 23 through the first liquid guide hole 25 of the rotating shaft 23, and then flows into the box 13 through the liquid guide pipe 36. The purification mechanism operates synchronously: the rotating shaft 23 drives the connecting rod 29 and scraper 28 to rotate, and the scraper 28 naturally contacts the inner wall of the tank 13 to scrape off the attached impurities; the water in the tank 13 flows into the purification plate 34 through the rotating pipe 33 at the bottom of the rotating shaft 23 and the second liquid guide hole 30, and the filter media in the collection tank 35 deeply purifies the water, removing fine impurities and harmful substances. Finally, the purified water enters the liquid guide plate 32 through the filter holes of the purification plate 34, and the rotating shaft 23 drives the rotating pipe 33 and the liquid guide plate 32 to rotate, so that multiple liquid outlet pipes 31 evenly discharge the purified water back to different areas of the cultivation tank 1, completing the whole-area water circulation purification. The inspection plate 26 of the top tank 24 can be opened to clean or replace the filter cover 38, and the top cover 27 of the tank 13 facilitates internal maintenance, ensuring the continuous and efficient operation of the device.
