Parallel-line-type oxygen supply system of aquaculture pond

Abstract

The invention relates to a parallel-line-type oxygen supply system of an aquaculture pond. The parallel-line-type oxygen supply system comprises multiple longitudinally-parallel oxygen supply pipelines, a supporting limiting filter net, two electromagnetic valves and an oxygen pump, the oxygen supply pipelines are arranged at the bottom of the aquaculture pond, the supporting limiting filter net is arranged on the oxygen supply pipelines, the oxygen pump is connected with the electromagnetic valves, multiple ventilation holes are formed in each oxygen supply pipeline along the extending direction, height of the supporting limiting filter net is larger than diameter of each oxygen supply pipeline, and the electromagnetic valves control opening and closing of the oxygen supply pipelines in a spaced manner respectively. The oxygen supply pipelines supply oxygen to the whole aquaculture pond, the supporting limiting filter net effectively prevents deviation of the oxygen supply pipelines and blockage of the ventilation holes of the oxygen supply pipelines, and large-area oxygen supply is realized through control; oxygen supply quantity of the oxygen supply pipelines is controlled by controlling the electromagnetic valves to be opened or closed half or fully, and oxygen is supplied to the aquaculture pond according to different needs. The supporting limiting filter nets and the bottom of the aquaculture pond are in round-corner transition connection, so that difficulty in cleaning of dead corners formed by dirt is avoided.

Description

technical field [0001] The invention relates to the field of aquaculture equipment, in particular to a parallel-line oxygen supply system for aquaculture ponds. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture includes extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and to grow aquatic products completely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas. Intensive farming is the use of bait and fertilization methods to grow aquatic products in smaller water bodies, such as pond fish farming, cage fish farm...

AI Technical Summary

Problems solved by technology

[0003] In high-density intensive culture, a large area of ​​oxygen supply is required in the culture pond, and the existing oxygen supply method is one-point or multi-point oxygen supply, which cannot meet the demand for large-area oxygen supply
