Description

Technical Field

[0001] This utility model relates to the field of oxygen supply equipment technology, and in particular to a multi-point oxygen supply device for Australian freshwater crayfish farming. Background Technology

[0002] The Australian freshwater crayfish, also known as the redclaw crayfish, belongs to the family Pseudococcidae in the order Decapoda. It is a large freshwater crayfish native to Australia. In recent years, this crayfish has been introduced and successfully farmed in Guangdong Province, achieving successful artificial breeding of seedlings and adult crayfish. Currently, its farming is being promoted both within and outside the province. With the continuous improvement of shrimp farming technology, high-density intensive shrimp farming has become the main farming method. Due to the large biomass per unit volume of water under high-density farming conditions, the required oxygen for respiration is high, and the oxygen content in the water is insufficient. Although Australian freshwater crayfish can tolerate low oxygen levels, prolonged survival in a low-oxygen environment will reduce immunity and affect feeding, molting, and growth. Therefore, aeration facilities are usually provided in the farming ponds. However, most existing aeration devices are fixed, resulting in uneven oxygen distribution in the water, which can easily cause oxygen deficiency in some freshwater crayfish. Utility Model Content

[0003] The purpose of this invention is to solve the problems existing in the above-mentioned background technology, and to propose a multi-point oxygen supply device for Australian freshwater crayfish farming.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-point oxygen supply device for Australian freshwater crayfish farming includes a culture pond, a fixed frame, and an oxygenator. A fixed frame is fixed above the fixed frame. The oxygenator is fixed to the left side of the upper surface of the fixed frame. A connecting pipe is fixed to the middle of the upper surface of the fixed frame. A servo motor is fixed to the right side of the upper surface of the fixed frame. A connecting column is vertically embedded in the middle of the fixed frame. A connecting plate is fixed to the upper outer wall of the connecting column. An oxygen supply plate is fixed to the bottom of the connecting column. Mounting plates are fixed to the front, back, left, and right ends of the outer wall of the oxygen supply plate. An oxygen supply column and a stirring blade are vertically fixed to the bottom of the mounting plate.

[0006] Preferably, a gear disk is provided on the drive shaft at the output end of the servo motor, and the servo motor is rotatably connected to the connecting disk through the gear disk.

[0007] Preferably, the oxygen supply column and the mounting plate are provided with a hollow channel that is connected to each other, and the other end of the hollow channel is connected to the interior of the oxygen supply disc.

[0008] Preferably, the bottom of the connecting tube is embedded above the inside of the connecting column, the outer wall of the connecting tube is in close contact with the inner wall of the connecting column, and the connecting column rotates horizontally on the outer wall of the connecting tube.

[0009] Preferably, the exhaust pipe of the oxygen supply machine is connected to the connecting pipe, and the oxygen supply machine is connected to the interior of the connecting pipe, the connecting column and the pipe through the connecting pipe.

[0010] Preferably, the oxygen supply column has 5-10 sets of exhaust holes arranged in a circular pattern at equal intervals from top to bottom inside, and a protective fine mesh is fixed on the outside of each exhaust hole. The stirring blade is arranged between adjacent oxygen supply columns.

[0011] 1. When Australian freshwater crayfish raised in the aquaculture pond require oxygen supply, the oxygen generated by the aerator enters the connecting pipe through the pipeline. Then, the oxygen flows along the connecting column, oxygen supply disc, and mounting plate into the exhaust hole of the oxygen supply column and is discharged. At the same time, the servo motor drives the connecting column, oxygen supply disc, mounting plate, oxygen supply column, and stirring blade to rotate simultaneously through the gear disc and connecting disc. As the oxygen supply column rotates in the water, it can simultaneously discharge oxygen into the water, achieving multi-point uniform oxygen supply in the aquaculture pond. The oxygen supply effect is good, further improving the survival rate of Australian freshwater crayfish.

[0012] 2. During the oxygen supply process, the servo motor drives the connecting column, oxygen supply plate, mounting plate, oxygen supply column and stirring blade to rotate simultaneously through the gear disk and connecting disk. At the same time, the stirring blade will stir the water and the oxygen discharged from the oxygen supply column. During the stirring process, the water and oxygen can be fully mixed, resulting in a better oxygen supply effect and further improving the survival rate of Australian freshwater crayfish.

[0017] Legend:

[0018] Aquaculture pond 1, fixed frame 2, oxygen supply machine 201, connecting pipe 202, servo motor 203, connecting column 204, connecting plate 205, oxygen supply plate 206, mounting plate 207, oxygen supply column 208, stirring blade 209. Detailed Implementation

[0019] Example 1, referring to Figure 1-4A multi-point oxygen supply device for Australian freshwater crayfish farming includes a farming pond 1, a fixed frame 2, and an oxygen supply machine 201. The fixed frame 2 is fixed above the fixed frame 2. The oxygen supply machine 201 is fixed on the left side of the upper surface of the fixed frame 2. The connecting pipe 202 is fixed in the middle of the upper surface of the fixed frame 2. The servo motor 203 is fixed on the right side of the upper surface of the fixed frame 2. The connecting column 204 is vertically embedded in the middle of the fixed frame 2. The connecting plate 205 is fixed on the upper part of the outer wall of the connecting column 204. The oxygen supply plate 206 is fixed at the bottom of the connecting column 204. The mounting plates 207 are fixed at the front, back, left, and right ends of the outer wall of the oxygen supply plate 206. The oxygen supply column 208 and the stirring blade 209 are vertically fixed at the bottom of the mounting plate 207.

[0020] A gear disk is provided on the drive shaft at the output end of the servo motor 203, and the servo motor 203 is rotatably connected to the connecting disk 205 through the gear disk;

[0021] The oxygen supply column 208 and the mounting plate 207 are provided with a hollow channel that is connected to each other, and the other end of the hollow channel is connected to the interior of the oxygen supply plate 206.

[0022] When the Australian freshwater crayfish raised in the aquaculture pond need oxygen, the oxygen generated by the oxygenator 201 enters the connecting pipe 202 through the pipe. Then, the oxygen enters the exhaust hole of the oxygen supply column 208 through the connecting column 204, the oxygen supply plate 206 and the mounting plate 207, thereby supplying oxygen to the aquaculture pond 1.

[0023] The bottom of the connecting tube 202 is embedded in the upper part of the connecting post 204, the outer wall of the connecting tube 202 is in close contact with the inner wall of the connecting post 204, and the connecting post 204 rotates horizontally on the outer wall of the connecting tube 202.

[0024] During the rotation of the connecting column 204, since the connecting pipe 202 is fixed on the fixing frame 2 and its bottom is embedded in the connecting column 204, the connecting column 204 will always rotate below the outside of the connecting pipe 202. As a result, when the oxygen generated by the oxygen supply machine 201 enters the connecting column 204, it will move further down into the connecting plate 205.

[0025] The pipe at the exhaust end of the oxygen supply machine 201 is connected to the connecting pipe 202, and the oxygen supply machine 201 is connected to the internal parts of the connecting pipe 202, the connecting column 204, and the pipe through the connection pipe 202.

[0026] During the oxygen supply process, the servo motor 203 drives the connecting column 204, oxygen supply plate 206, mounting plate 207, oxygen supply column 208 and stirring blade 209 to rotate simultaneously through the gear disk and connecting disk 205. As the oxygen supply column 208 rotates in the water, it can simultaneously discharge oxygen into the water, realizing multi-point uniform oxygen supply in the breeding pond. The oxygen supply effect is good, which further improves the survival rate of Australian freshwater crayfish.

[0027] Example 2 differs from Example 1 in that, in this example, the oxygen supply column 208 has 5-10 sets of exhaust holes arranged in a circular pattern at equal intervals from top to bottom, and protective fine mesh is fixed on the outside of each exhaust hole. The stirring blades 209 are arranged between adjacent oxygen supply columns 208.

[0028] The main function of the protective fine net is to prevent debris in the aquaculture pond 1 from entering the interior of the oxygen supply column 208, while also breaking the discharged oxygen into smaller bubbles to fully mix with the water.

[0029] During the oxygen supply process, the servo motor 203 drives the connecting column 204, oxygen supply plate 206, mounting plate 207, oxygen supply column 208 and stirring blade 209 to rotate simultaneously through the gear disk and connecting disk 205. At the same time, the stirring blade 209 stirs the water and the oxygen discharged from the oxygen supply column 208. During the stirring process, the water and oxygen can be fully mixed, resulting in a better oxygen supply effect and further improving the survival rate of Australian freshwater crayfish.

[0030] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
