Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, in particular to a device for cleaning residual food and excrement for an aquaculture pond. Background Art

[0002] Aquaculture ponds are production facilities for the reproduction, cultivation and harvesting of aquatic plants and animals under human control. It is usually a relatively closed and concentrated ecosystem, with an area and depth designed according to aquaculture needs, and equipped with independent water inlet and outlet systems, as well as aeration, feeding and other aquaculture facilities. In this system, the ecological balance of water quality and the healthy growth of farmed animals are maintained through metabolic functions such as photosynthesis and respiration. There are various types of aquaculture ponds, including standardized ponds, high-standard ponds and circulating water aquaculture ponds. These different types of aquaculture ponds have their own characteristics in scale, structure and management. At the same time, in order to improve aquaculture efficiency and output, farmers will also reasonably control the stocking density, feed high-quality bait, and conduct regular water quality monitoring and maintenance according to the needs and growth stages of farmed animals.

[0003] The cleaning of leftover food and feces in aquaculture ponds is an important part of ensuring water quality and fish health, so a leftover food and feces cleaning device is needed. The existing cleaning device usually captures leftover food and feces in the water through a screen structure when in use, but the existing technology cannot classify and clean leftover food and feces of different particles. Leftover bait and feces that are not classified and cleaned will lead to an increase in suspended matter in the water body, affecting the transparency of the water body and reducing the efficiency of photosynthesis. The leftover bait and feces that are not classified and cleaned contain a large amount of unused feed components, resulting in feed waste and increased breeding costs. The existing technology usually pumps pool water into the cleaning device for cleaning, but the floating leftover food and feces in the aquaculture pond cannot be effectively cleaned. The floating objects will block sunlight, reduce the transparency of the water body, affect the efficiency of photosynthesis, and cause a decrease in the dissolved oxygen content in the water. The organic matter in the floating objects will consume oxygen and produce harmful substances such as ammonia nitrogen and hydrogen sulfide during the decomposition process, deteriorating the water quality. The accumulation of floating objects will destroy the ecological balance of the water body, leading to excessive growth or death of aquatic plants and algae, and reducing biodiversity.
