An ecological aeration device for fish ponds

Abstract

The invention discloses an ecological aeration device for fishponds, which comprises a floating board floating on the water surface, moss is planted on the upper wall of the floating board, and a rotating rod is connected to the middle part of the floating board through bearing rotation. A plurality of upper rails are fixed on the upper side of the floating plate, and a plurality of lower rails are fixedly connected to the lower wall of the floating plate through a hard connecting rod. The number of the upper rails and the lower rails are equal and correspond to each other. The above-mentioned upper rails and the lower rails directly below are equipped with a chain box together, and the chain box is connected in series by a plurality of unit boxes to form a ring. The advantage is that: the action of sunlight in the present invention can make the oxygen content around the device of the present invention higher, so that more fish gather around the device, and the fish will drive the blades to rotate when they move, and the blades will drive the rotating rod to rotate. The chain box can be moved so that the unit box with air on the water surface can be moved down into the water, and the air in the unit box can escape to increase the oxygen content of the water body.

Description

technical field [0001] The invention relates to the technical field of fish pond cultivation, in particular to an ecological aeration device for fish ponds. Background technique [0002] my country is a big country in the world for aquaculture. The area of ​​pond aquaculture alone reaches about 20 million mu, and the aquaculture output ranks first in the world. Recently, with the continuous expansion of aquaculture area and breeding density in our country, the weather conditions are getting worse and worse, and the requirements for dissolved oxygen in aquatic products are getting higher and higher. Low dissolved oxygen makes it breathe faster, and it is easy to cause floating head phenomenon, or even lead to the death of aquatic products. [0003] In the prior art, the aerator is used to increase the oxygen of the water body. Most of the aerators in the prior art pump air into the water through an air pump to increase the dissolved oxygen. For ponds with larger water surfac...

Problems solved by technology

[0003] In the prior art, the aerator is used to increase the oxygen of the water body. Most of the aerators in the prior art pump air into the water through the air pump to increase the dissolved oxygen. For ponds with larger water surfaces, more power is required. The air pump, and the start of the aerator needs to be manually observed and controlled to see if the water body is hypoxic, which not only consumes a lot of resources such as electricity, but also consumes a lot of manpower.
