Problems solved by technology

[0006] However, the above-mentioned oxygenation devices are all by stirring the water body, pumping air into the water body or pumping the water from the bottom of the water body to the top layer. The oxygenation method is single, and different equipment needs to be replaced according to different depths. The scope of application is small. The method of agitating the water body to increase oxygen is very restrictive, and it is easy to disturb the fish. When increasing the oxygen by pumping water, it is necessary to continuously pump the water from the bottom layer to the top layer. The movement of the entire layer of water body is relatively large. inconvenient

Abstract

The invention discloses a layered oxygenation device for pond aquaculture in the technical field of aquaculture. The layered oxygenation device comprises a top box, a connection box, a bottom box, a first driving mechanism, a second driving mechanism and a third driving mechanism. The layered oxygenation device has the advantages that the first driving mechanism, the second driving mechanism and the third driving mechanism drive corresponding moving rods and pistons to reciprocate through a rotating motor, the air continuously enters a first air cylinder, a second air cylinder and a third aircylinder before being discharged into the water, a third liquid inlet cylinder of the bottom box sucks in the water on the bottom layer and discharges the water through a communication pipe and a second liquid discharge cylinder, a second liquid inlet cylinder of the connection box sucks the water on the middle layer and discharges the water through a communication pipe and a first liquid discharge cylinder, the water on the bottom and middle layers moves upwards continuously through layering, the air is added to the water on each layer, two oxygenation modes are combined, and accordingly, theoxygenation efficiency and effect are improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a layered aeration device for pond aquaculture. 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. [0003] Fish farming in aquaculture ponds is a relatively common intensive farming method. Since the water in aquaculture ponds is not constantly flowing, it is necessary to increase the oxygen in the aquaculture pond water during the aquaculture process to ensure sufficient oxygen in the water body and avoid aquaculture fish. lack of oxygen. [0004] According to the depth of water...
