Description

Technical Field

[0001] The utility model relates to the technical field of water circulation devices, in particular to a water circulation device for an aquaculture pond. Background Art

[0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic plants and animals under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial feeding and management. In a broad sense, it can also include the proliferation of aquatic resources. Generally, since there is no good water circulation treatment device in the breeding pond, the water in the breeding pond is directly discharged into the ground through the drainage pipe, which wastes a lot of water resources. At the same time, a large amount of fish feces often accumulates in the breeding pond, which can be processed into natural fertilizer for the cultivation of crops.

[0003] Chinese patent publication number CN218851647U discloses an aquaculture water circulation device. The technical solution uses a pumping structure and a filtering device. When in use, an electric valve is opened, and a first water pump pumps water from the culture pond through a pumping pipe. The water passes through the water pump and the water pipe and enters the filter box. Then, the water is filtered through a filter barrel so that feces and soil in the water remain above the filter barrel. The water flows down through the filter barrel to the bottom of the inner cavity of the filter box. After the filtering is completed, the handle is pulled to lift the top plate and the pull rod. The pull rod drives the baffle plate to rise and pull out the filter barrel for cleaning and recycling, thereby realizing the filtration and recycling of fish feces and reducing the waste of resources.

[0004] During use, the water circulation device uses a single filter barrel for filtering. During the cleaning process, the device cannot be used for filtering, and the cleaning operation requires manual operation by the staff. The cumbersome cleaning operation results in a long time consumption, which is not conducive to the water circulation of the aquaculture pond. Utility Model Content
