Problems solved by technology

[0002] In the process of modern production and breeding, aerators are widely used in aquatic products, but a sudden failure of the aerator or a sudden power failure will lead to hypoxia or even death
In wild aquaculture ponds, aerators are often needed due to the insufficient oxygen content of lake water. However, in the wild environment, the power of aerators generally comes from electric motors or diesel engines. These devices often have high operating costs and are cumbersome to use.
[0003] In the process of Chinese sturgeon breeding, most of the breeding ponds adopt live water culture, and the water in the drainage channel is drained directly or after water treatment. There are no reports of using the hydraulic power in the drainage channel, which wastes a lot of water. water resources

Embodiment 1

[0027] like Figure 1~2 Among them, a circulating water-driven aquaculture pond oxygenation device, the hydraulic device 2 arranged in the drainage channel 3 is connected to the driving mechanism through the transmission mechanism 4, the driving mechanism is connected to the air pump and drives the air pump to act, and the air pump passes through the exhaust one-way valve 9 It is connected with the microporous aeration device 14 located in the culture pond 1 . With this structure, the water flow in the drainage channel 3 drives the hydraulic device 2 to rotate so as to drive the driving mechanism to move, and the driving mechanism drives the air pump to move, thereby sending the gas into the microporous aeration device 14 after being pressurized. Gas therefore needs to be provided with an exhaust one-way valve 9 that can only be exhausted but not inhaled. The microporous aeration device 14 is a tube with micropores, or a cavity with micropores on the top. Compressed air is di...

Embodiment 2

[0029] On the basis of Example 1, the preferred scheme is as figure 1 , 2 Among them, the hydraulic device 2 is a waterwheel, and the waterwheel is provided with a water tank 24 arranged obliquely, and the water tanks 24 are evenly distributed along the circumference of the waterwheel. With this structure, the position of the water wheel at the middle elevation from top to bottom faces the drainage channel 3, and the gravity difference formed by receiving water from the water tank pushes the water wheel to rotate, and the water tank runs to the bottom of the water wheel, and the water is discharged from the water tank to reduce weight. In this example, it is preferable to use a water tank with a rectangular cross section, the width of which is the same as that of the drainage channel 3, so as to increase the torque of the waterwheel. Thereby it is convenient to adopt the transmission mechanism of increasing speed. The transmission mechanism in this example is a chain transm...

Embodiment 3

[0031] On the basis of Example 1, the preferred scheme is as Figure 4 Among them, the hydraulic device 2 is a belt waterwheel 2', at least two pulleys 21 are arranged along the drainage channel 3, the belt 22 goes around the two pulleys 21, and water buckets 23 or buckets are evenly distributed on the belt 22. Paddle board, water bucket 23 or paddle board run to below belt wheel 21 when, be positioned at the water of drainage channel 3. The waterwheel takes up a lot of space, while the belt waterwheel 2' in this example has the advantage of taking up little space. Moreover, the hydraulic utilization rate of the water flow in the drainage channel 3 is high.

Abstract

The invention provides a circulating water-driven aquaculture pond oxygenation device, which relates to the field of rare fish aquaculture. Its structure is: a hydraulic device arranged in a drainage channel is connected to a drive mechanism through a transmission mechanism, and the drive mechanism is connected to an air pump to drive the air pump Action, the air pump is connected with the microporous aeration device through the exhaust one-way valve. By adopting the above structure, the hydraulic power in the drainage channel can be converted into the power of the aeration device, thereby making full use of water resources and reducing the energy consumption of breeding. The device of the invention can also be used with other fish species.

Description

technical field [0001] The invention relates to the field of rare fish breeding, in particular to a circulating water-driven aquaculture pond oxygenation device that can be used for Chinese sturgeon aquaculture. Background technique [0002] In the process of modern production and breeding, aerators are widely used in aquatic products, but a sudden breakdown of the aerator or a sudden power failure will lead to hypoxia or even death. In wild aquaculture ponds, aerators are often needed due to the lack of oxygen in the water flow of lakes. However, in the wild environment, the power of aerators generally comes from electric motors or diesel engines. These devices often have high operating costs and are cumbersome to use. . [0003] In the process of Chinese sturgeon breeding, most of the breeding ponds adopt live water culture, and the water in the drainage channel is drained directly or after water treatment. There are no reports of using the hydraulic power in the drainage...
