Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture, and in particular to an oxygenation device for shellfish aquaculture. Background Technology

[0002] Shellfish meat is edible and has extremely high economic and nutritional value, making shellfish farming quite common. Shellfish can be farmed in ponds, but oxygenation is necessary to ensure their survival rate. However, the aeration devices cannot be repositioned or stably placed within the ponds.

[0003] Therefore, those skilled in the art have provided an oxygenation device for shellfish aquaculture to solve the problems mentioned above. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an oxygenation device for shellfish aquaculture.

[0005] The oxygenation device for shellfish aquaculture provided by this utility model adopts the following technical solution:

[0006] An aeration device for shellfish aquaculture includes a central block. Two side plates are symmetrically fixedly installed on the side of the central block. Insert blocks are slidably inserted into the side plates. An inner groove is opened in the insert block. Multiple springs are fixedly installed between the inner wall of one side of the inner groove and the inner wall of one side of the side plate. A bracket is fixedly installed on one side of the insert block. A vertical column is inserted into the central block. A connecting column is fixedly installed at the bottom of the vertical column. An aeration structure is fixedly installed at the bottom of the connecting column, which can be easily placed above the aquaculture pond.

[0007] Preferably, four limiting plates are symmetrically fixedly installed on the side of the vertical column. The limiting plates pass through the central block to prevent the oxygenation structure from rotating.

[0008] Preferably, a second spring is fitted on the vertical column, with the top end of the second spring fixedly installed on the top of the vertical column and a sleeve plate fixedly installed on the bottom end of the second spring. The sleeve plate is fitted on the vertical column and can provide buffer protection when the oxygenation structure descends.

[0009] Preferably, two square slots are symmetrically opened on the central block, and a square block is slidably inserted into the square slot. A locking block is fixedly installed on one side of the square block, and a lever is fixedly installed on the other side of the square block. A spring is sleeved on the lever, and the lever penetrates through the side wall of the central block. Multiple slots are symmetrically opened on the side of the vertical column, and the locking block is inserted into the slot, which can adjust the depth of the oxygenation structure in the water.

[0010] Preferably, the bottom of the oxygenation structure is symmetrically fixed with multiple support legs, which can support the oxygenation structure and provide good overall stability.

[0011] In summary, this utility model has the following beneficial technical effects:

[0012] 1. Pulling the card holder horizontally allows the insert to be pulled out from the side plate. Under the action of spring one, the card holder can be locked onto the side of the breeding pond and the crossbar arranged on the breeding pond. The distance between the two card holders is adjustable, which makes it convenient to place them and also facilitates the adjustment of the overall position.

[0013] 2. The limiting plate can restrict the rotation of the vertical column and the aeration structure. The block and the square groove cooperate to restrict the rotation of the lever. Under the action of spring three, the locking block can be inserted into the slot to limit and fix the vertical column downward. When it is necessary to adjust the height of the aeration structure upward, the vertical column can be pulled upward directly without the locking block limiting the slot. When it is necessary to adjust the height of the aeration structure downward, both levers can be pulled at the same time to release the restriction on the vertical column. Spring two can buffer the downward aeration structure and then pull it upward to adjust to a suitable height. It can be inserted into different depths of the aquaculture pond for convenient aeration.
