Description

Aquaculture equipment

Technical Field

The utility model belongs to the technical field of aquaculture, especially, relate to an aquaculture equipment.

Background

For the cultivation of freshwater shrimps, aquatic plants such as submerged plants, floating leaves and the like need to be planted in a pond. The aquatic plants can provide food sources for the freshwater shrimps, can also play a role in purifying water quality, and can also provide places and spaces for unshelling, hiding and phototaxis for the freshwater shrimps. Therefore, the theory that one pond of shrimp needs to be raised and one pond of grass needs to be planted firstly is provided.

However, the large-area planting and proliferation of aquatic weeds in ponds also brings some disadvantages. Because photosynthesis makes pond dissolved oxygen be saturated daytime, because photosynthesis stops night, the pasture and water carries out dark reaction, needs to consume a large amount of dissolved oxygen, can often appear the oxygen deficiency phenomenon night, and this phenomenon is more serious more the pasture and water is more. Therefore, the shrimp culture pond is necessary to be provided with an oxygen increasing facility.

The existing shrimp culture pond is equipped with aeration facilities which mainly comprise a waterwheel, a flushing type aeration device, a micro-pipe, an aeration head and the like. The flow of water in the shrimp pond is increased through a waterwheel, a flushing type oxygen increasing device and the like, the contact area of the water and air is increased, and the oxygen content of the water is further improved; or air or oxygen is introduced into the water through the micro-pipe and the inflating head to improve the oxygen content of the water.

The applicant of the present invention finds out in implementing the above technical solution that the above technical solution has at least the following drawbacks:

due to the existence of waterweeds, the water truck and the flushing type oxygenation device have limited improvement on the mobility of the water in the shrimp culture pond, the oxygenation effect is poor, the freshwater shrimps are sensitive to the flow velocity of the water, and the large flow velocity is not beneficial to the growth of the freshwater shrimps; meanwhile, the waterwheel and the flushing type oxygen increasing device have large noise during operation, and can also influence the growth of the freshwater shrimps. The micro-tube and the inflating head are used for inflating air into water, a large amount of aquatic weeds can also block the air, so that the inflating range is limited, in addition, when bubbles filled into the water rise, the oxygen-enriched water can be brought to the surface layer, and freshwater shrimps do not like the bubbles and mainly live on the aquatic weeds, so that the actual oxygen increasing effect is limited, and the oxygen requirement of the freshwater shrimps on the oxygen cannot be met.
