Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of crayfish farming equipment, specifically an aerator for crayfish farming. Background Technology
[0002] In crayfish (such as baby crayfish) farming, dissolved oxygen levels in the water are a key factor affecting their growth, survival rate, and health. Crayfish are benthic organisms, often inhabiting the bottom of ponds or rice paddies. Traditional aeration equipment (such as waterwheel aerators and impeller aerators) mainly works on the upper and middle layers of the water, making it difficult to effectively increase dissolved oxygen levels at the bottom. This leads to oxygen deficiency at the bottom, affecting the crayfish's feeding, molting, and disease resistance.
[0003] Existing technologies include methods that utilize nano-oxygenation tubes to oxygenate the bottom of water bodies. These tubes generate tiny bubbles through micron-sized pores, improving oxygen dissolution efficiency and promoting water flow. However, most existing nano-oxygenation tubes are installed independently and are not designed in conjunction with the lobster's habitat, resulting in a disconnect between the oxygenation effect and the lobster's ecological needs. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an aerator for lobster farming.
[0005] The technical solution of this utility model is:
[0006] An aerator for lobster farming, comprising:
[0007] The shrimp nest is composed of several aquaculture boards that can be spliced together vertically or horizontally. Each aquaculture board includes several aquaculture tubes. An oxygenation tank is provided through one side of the aquaculture tube along its axis. An oxygenation pipeline is slidably installed in the oxygenation tank. The oxygenation pipeline is connected to an air compressor, which generates compressed air and supplies oxygen to the shrimp nest through the oxygenation pipeline.
[0008] Preferably, the oxygenation tank is C-shaped, and oxygenation holes are radially penetrating inside the oxygenation tank, with the oxygenation holes evenly arranged along the axial direction of the oxygenation tank.
[0009] Preferably, the aquaculture tubes are connected by a connecting plate, and the top and bottom surfaces of the aquaculture tubes are provided with a first buckle, which is used for splicing the aquaculture plates together.
[0010] Preferably, when the aquaculture board is spliced together, the space enclosed by the connecting board and the outer side of the aquaculture tube can be used for lobsters to hide.
[0011] Preferably, a second snap-fit device is provided on the outermost side of the aquaculture tube, which is used for splicing the aquaculture board from left to right.
[0012] Preferably, the oxygenation pipeline includes an oxygenation main pipe, one end of which is connected to an air compressor, and the other end is connected to several oxygenation branch pipes via a distribution pipe.
[0013] Preferably, the oxygenation branch pipe is connected to a plurality of aeration pipes, which are slidably installed in the oxygenation tank, and the aeration pipes are provided with tiny air holes.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention provides oxygen to shrimp nests by installing an oxygenation tank and oxygenation holes inside the aquaculture pipe, using an oxygenation pipeline to deliver compressed air into the aquaculture pipe, and using the oxygenation holes to diffuse oxygen. By injecting air into the oxygenation tank, the water flow inside the aquaculture pipe is promoted, preventing the accumulation of shrimp excrement in the shrimp nests. The aquaculture board is connected vertically using a first snap-fit mechanism and horizontally using a second snap-fit mechanism, which allows for easy adjustment of the shrimp nest size and makes the shrimp nest setup more flexible.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Example 1:
[0028] Please see Figure 1-5 The present invention will describe the above technical solution in detail through the following embodiments:
[0029] An aerator for lobster farming, comprising:

The aquaculture board 2 includes several aquaculture tubes 21. An oxygenation tank 22 is provided through one side of the aquaculture tube 21. An oxygenation pipe 3 is slidably installed in the oxygenation tank 22. The oxygenation pipe 3 is connected to an air compressor 4. The air compressor 4 is used to generate compressed air and supply oxygen to the shrimp nest 1 through the oxygenation pipe 3.
[0031] Air compressor 4 can be a known air compressor.
[0032] The cross-section of the aquaculture tube 21 is a regular hexagon. The top and bottom surfaces of the aquaculture tube 21 are parallel to the horizontal plane. The oxygenation tank 22 is located at the intersection of the two inclined surfaces on the right side.
[0033] The oxygenation tank 22 is C-shaped, and oxygenation holes 23 are provided radially through the interior of the oxygenation tank 22. The oxygenation holes 23 are evenly arranged along the axial direction of the oxygenation tank 22.
[0034] The oxygenation hole 23 is used to connect the upper right and lower right spaces of the outside of the aquaculture tube 21 with the inside of the aquaculture tube 21.
[0035] The breeding tubes 21 are connected by a connecting plate 24, and the top and bottom surfaces of the breeding tubes 21 are provided with first buckles 25.
[0036] The first clip 25 is used for splicing the upper and lower parts of the breeding board 2.
[0037] The first buckle 25 is located at the end of the culture tube 21 and extends to the outside perpendicularly to the top and bottom surfaces of the culture tube 21. Two buckles on the same side are symmetrical about the center of the culture tube 21.
[0038] When the aquaculture board 2 is spliced together, the space enclosed by the connecting board 24 and the outer side of the aquaculture tube 21 can be used for lobsters to hide.
[0039] When the breeding plate 2 is engaged from top to bottom using the first buckle 25, the connecting plate 24 and the outer side of the breeding tube 21 form a hexagonal space.
[0040] The outermost aquaculture tube 21 is provided with a second snap-fit device, which is used for splicing the left and right sides of the aquaculture plate 2.
[0041] The second snap-fit device includes two expansion plates 26, which are located outside the outermost breeding tube 21. The outer sides of the two expansion plates 26 are respectively provided with guide grooves 27 and guide protrusions 28. The guide protrusions 28 and guide grooves 27 are adapted to each other. The guide protrusions 28 can be snapped into the guide grooves 27 and can slide along the guide grooves 27, so as to realize the left and right connection of the breeding plate 2.
[0042] The oxygenation pipeline 3 includes an oxygenation main pipe 31. One end of the oxygenation pipeline 3 is connected to the air compressor 4, and the other end is connected to several oxygenation branch pipes 33 through a distribution pipe 32.
[0043] The distribution pipe 32 is used to evenly distribute the compressed air delivered by the oxygenation main pipe 31.
[0044] The oxygenation branch pipe 33 is connected to several aeration pipes 35. The aeration pipes 35 are slidably installed in the oxygenation tank 22, and the aeration pipes 35 are provided with tiny air holes.
[0045] An air outlet pipe 34 is provided radially on the outer side of the oxygenation branch pipe 33. The air outlet pipes 34 are evenly arranged along the axial direction of the oxygenation branch pipe 33. One end of the aeration pipe 35 is connected to the air outlet pipe 34, and the other end of the aeration pipe 35 is connected to a plug 36.
[0046] The aeration tube 35 can be a known nano-oxygen supply tube.
[0047] In this embodiment, when using this equipment, the operator selects different numbers of breeding boards 2 according to the actual breeding area and breeding quantity.
[0048] The first buckle 25 is used to snap the aquaculture board 2 together vertically, and the guide groove 27 and guide protrusion 28 are used to snap it together to connect the aquaculture board 2 horizontally, so that several aquaculture boards 2 can be spliced together to form a shrimp nest 1.
[0049] Insert the aeration pipe 35 into the oxygenation tank 22, block one end of the aeration pipe 35 with the plug 36, and connect the other end to the air outlet pipe 34.

[0050] Place the shrimp nest 1, which is connected to the oxygenation pipe 3, into the water.
[0051] When the air compressor 4 is working, it generates compressed air and then delivers the compressed air to the distribution pipe 32 through the oxygenation main pipe 31. The compressed air is then evenly distributed to several oxygenation sub-pipes 33 through the distribution pipe 32. The compressed air enters the aeration pipe 35 from the outlet pipe 34 and finally exits from the small hole on the aeration pipe 35.
