Embodiment Construction

[0016] As shown in the figure, the underwater aeration panel for aquaculture includes a main pipe 3 and a plurality of branch pipes 4 connected to the main pipe 3 , and a main valve 1 and a check valve 2 are arranged on the main pipe 2 . The non-return valve 2 is composed of an inner tube 201 and an outer tube 203 that are set and bonded together, and a rubber sleeve 202 that is fixed between the inner tube 201 and the outer tube 203 at one end. The other end of the rubber sleeve 202 is provided with a gap 202a, and the parts of the rubber sleeve 202 located on both sides of the gap 202a are inclined. An air chamber 6 is connected to the end of the branch pipe 4 through a connecting pipe 5 , and micropores 601 are provided on the air chamber 6 . The air chamber 6 is made of a hollow air stone.

[0017] When in use, connect the connecting air pipe to the intake end of the main pipe 4, then put the aeration disk into the bottom of the water, and after the aeration pump is turne...

Abstract

The invention relates to an underwater aeration disk for aquaculture, comprising a main pipe, multiple branch pipes connected with the main pipe. The invention is characterized in that a check valve is arranged on the main pipe. The invention has the following advantages: as the main pipe is provided with the check valve, the invention can prevent seawater encroachment, prevent water from entering connecting pipes and icing in the winter, facilitate aeration, is free from the influence of placement direction of the aeration disk, is applicable to different underwater terrains, can improve water quality environment and bottom materials, solve water body layering problem and facilitate growth of sea cucumbers.

Description

technical field [0001] The invention particularly relates to an underwater aeration tray for aquaculture. Background technique [0002] The underwater aeration tray for aquaculture is mainly used for sea cucumber cultivation. The existing underwater aeration tray for aquaculture is composed of a main pipe and branch pipes connected with the main pipe, and the branch pipes are evenly distributed with fine holes. When the aeration disk with this structure is not oxygenated, seawater will flow back from the fine holes on the branch pipe to the main pipe and enter the connecting pipeline connected with the main pipe, which will increase the pressure in the connecting pipeline and make it difficult to achieve oxygenation. In addition, in winter, there will be ice on the upper end of the connecting pipeline, that is, at the water surface, and oxygen cannot be pumped at all. [0003] Contents of the invention [0004] The technical problem to be solved by the present invention...
