Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an aeration device used in an aquaculture pond. Background Art

[0002] In aquaculture ponds or ponds, in order to increase the oxygen content in the water and promote the improvement of the water environment, it is often necessary to lay a large number of nano aeration tubes. The air is pressed into the oxygen delivery pipeline by a fan and then sent into the nano aeration tube. The air is dispersed into the water in the form of microbubbles. The microbubbles float from the bottom to the top, prompting the oxygen to fully dissolve into the water, causing the water to rotate and flow up and down, so that the oxygen-rich water in the upper layer of the pond or aquaculture pond is brought to the bottom layer, achieving uniform oxygenation of the pool water.

[0003] However, in the actual aeration process of aquaculture ponds, the gas is input into the nano aeration tube by an external fan. The nano aeration tube near the fan has more oxygen in the pipeline, while the nano aeration tube far from the fan has less oxygen. This leads to uneven aeration of the nano aeration tube as a whole, which means that the oxygen content in some areas is low, and the activity of the fry in these areas is limited. At the same time, in areas with excessive oxygen, the excess oxygen may cause the animal's body cells to breathe too excitedly, making it unable to eat and live normally. Prolonged excitement will lead to body weakness or even death, affecting the normal growth of the fry. To this end, we provide a device for uniform aeration of the nano aeration tube in an aquaculture pond. Utility Model Content

[0004] The utility model provides an aeration device for aquaculture ponds, aiming to solve the problems that the existing aeration device for aquaculture ponds cannot realize uniform aeration of the nano aeration pipe as a whole, thus affecting the normal growth of fry.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An aeration device for an aquaculture pond comprises an air intake main pipe, an oxygen flow regulating switch, a connecting hose and a nano aeration pipe.

Each aeration unit is connected to the air intake main pipe via a connecting hose. Each connecting hose is also connected with an oxygen flow regulating switch.

[0007] Furthermore, the air intake main pipe is arranged in a circular ring shape along the top edge of the aquaculture pond, and the air intake end of the air intake main pipe is connected to the oxygen delivery pipeline through a three-way pipe.

[0008] Furthermore, the oxygen flow regulating switch is installed at the connection between the air intake main pipe and the connecting hose.

[0009] Furthermore, the oxygen flow regulating switch is an automatic switch or a manual switch.

[0010] Furthermore, a plurality of connection ports are provided on the top of the air intake main pipe, the manual switch comprises a T-tube and bolts, the T-tube comprises a first branch pipe and a second branch pipe, the bottom of the first branch pipe is connected to a connection port, the top of the first branch pipe is provided with a threaded through hole communicating with the connection port, one end of the second branch pipe is connected to the side wall of the threaded through hole of the first branch pipe, the other end of the second branch pipe is connected to the connecting hose, and the bolts are connected to the threaded through holes accordingly.

DETAILED DESCRIPTION

[0018] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details. For well-known components, methods and processes, they are not described in detail below.

[0019] An aeration device for aquaculture ponds, referring to Figure 1 and Figure 2 , including an air intake main pipe 10, an oxygen flow regulating switch 20, a connecting hose 30 and a nano aeration pipe 40. The air intake main pipe 10 is connected with a plurality of connecting hoses 30 at intervals along the extending direction of the pipe. The air intake main pipe 10 is arranged in a circular ring along the top edge of the aquaculture pond 50. The nano aeration pipe 40 is arranged along the bottom edge of the aquaculture pond 50. A plurality of aeration holes are densely distributed on the nano aeration pipe 40. A plurality of baffles 60 are arranged at intervals in the nano aeration pipe 40. The baffles 60 separate the nano aeration pipe 40 into a plurality of independent and non-communicating aeration units. Each aeration unit is connected to the air intake main pipe 10 through a connecting hose 30.

[0020] Reference Figure 1 An oxygen flow regulating switch 20 for controlling the oxygen flow entering the connecting hose 30 is installed at the connection between the air intake main pipe 10 and the connecting hose 30. The oxygen flow regulating switch 20 is a manual switch 21 or an automatic switch.

[0021] Reference Figure 1 and Figure 2 The input end of the oxygen delivery pipeline 80 is connected to an external blower 70, and the air intake end of the air intake main pipe 10 is connected to the oxygen delivery pipeline 80 through a three-way pipe 81. The left and right ports of the three-way pipe 81 are connected to the air intake main pipe 10 to form a loop. After the oxygen enters the oxygen delivery pipeline 80 from the external blower 70, it is divided into two routes and input into the air intake main pipe 10 to prevent the oxygen from entering the air intake main pipe 10 through only one route, resulting in very little oxygen content reaching the end of the air intake main pipe 10.

[0022] Reference Figure 1 A control switch 82 is installed on the oxygen delivery pipeline 80, and a drain outlet 51 is provided at the bottom center of the aquaculture pond 50.

[0023] Reference Figure 1 and Figure 2The nano aeration tube 40 specifically shown in this embodiment is evenly divided into four independent and unconnected aeration units by four baffles 60. When the control switch 82 is turned on, oxygen is divided into two gas paths by the external fan 70 through the oxygen delivery pipeline 80 and the three-way pipe 81 and input into the air intake main pipe 10, and then respectively input into the four-stage aeration units through four connecting hoses 30. Each aeration unit includes an oxygen flow regulating switch 20.

[0024] The oxygen flow regulating switch 20 is a manual switch 21, which includes a T-tube 211 and a bolt 212. The T-tube 211 includes a first branch pipe 2111 and a second branch pipe 2112. A plurality of connection ports are provided on the top of the air intake main pipe 10. The bottom of the first branch pipe 2111 is connected to a connection port. The top of the first branch pipe 2111 is provided with a threaded through hole communicating with the connection port. The bolt 212 is connected to the threaded through hole correspondingly. One end of the second branch pipe 2112 is provided with an air intake port communicating with the side wall of the threaded through hole of the first branch pipe 2111. The other end of the second branch pipe 2112 is connected to the connecting hose 30. The bolt 212 is manually adjusted to move the screw rod of the bolt 212 upward along the axial direction of the threaded through hole to control the opening size at the air intake port of the second branch pipe 2112, so as to achieve the purpose of regulating the gas flow entering the connecting hose 30.

[0025] Of course, in other embodiments, the oxygen flow regulating switch 20 can also be an automatic switch, which includes a flow regulating valve and a controller. The flow regulating valve is electrically connected to the controller. The flow regulating valve controls the flow of the fluid by changing the opening of the valve. Specifically, when the valve opening increases, the cross-sectional area of ​​the fluid passing through the valve increases, and the flow also increases accordingly; conversely, when the valve opening decreases, the cross-sectional area of ​​the fluid passing through the valve decreases, and the flow decreases accordingly. The flow regulating valve is installed on the connecting hose 30. The controller controls the flow regulating valve to adjust the gas flow input into the four-stage aeration unit according to the air pressure difference of the air intake main pipe 10, so that the aeration volume of the four-stage aeration unit reaches a relatively uniform state, thereby improving the quality of the living environment of the fry.

[0026] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
