Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an oxygenation device suitable for outdoor pond aquaculture. Background Art

[0002] In aquaculture, oxygenation is an important means to increase breeding density and reduce breeding risks. At present, aquaculture is mainly divided into greenhouse breeding and outdoor pond breeding. Greenhouse breeding usually adopts bottom oxygenation for oxygenation, which has high breeding density and low breeding risk; outdoor pond breeding mostly adopts algae oxygenation and water wheel type surface oxygenation for oxygenation, and its breeding density is about one tenth of greenhouse breeding, and the breeding risk is uncontrollable.

[0003] In general, bottom aeration is the most effective way to increase oxygen. It uses nano-aeration tubes or aeration stones laid on the bottom of the water to release the air output by the aerator from the bottom of the water in the form of tiny bubbles. In the process of the bubbles rising to the surface, the oxygen inside fully dissolves into the water body, increasing the dissolved oxygen content of the water body. However, this method of oxygenation can only be used in greenhouse farming models with relatively complete infrastructure. At present, the most common breeding in my country is still in outer ponds. The outer ponds have the characteristics of irregular shapes and no hardened bottom surface, so it is impossible to lay aeration pipes at the bottom. The oxygenation effect of algae oxygenation and water wheel surface oxygenation is poor, so the problem of outer pond oxygenation needs to be solved urgently. Utility Model Content

[0004] In view of the defects in the prior art, the technical problem to be solved by the utility model is to provide an oxygenation device suitable for outdoor pond aquaculture, which can carry out bottom oxygenation of the outdoor pond without laying oxygenation pipelines, thereby improving the oxygenation effect of the outdoor pond, increasing the dissolved oxygen content of the aquaculture water, increasing the aquaculture density of the outdoor pond, reducing the aquaculture risk, and at the same time can also play the role of activating water.

A plurality of horizontally arranged nano aeration pipes are arranged in parallel between the two air distribution cross pipes along the length direction of the floating frame. Two ends of the nano aeration pipe are respectively connected and communicated with the two air distribution cross pipes. The exhaust ports of the nano aeration pipes are all arranged upward. An air supply component communicated with one of the air distribution cross pipes is arranged outside the floating frame.

[0008] As an optimized solution, the air supply component includes an air suspension aerator. An air inlet pipe communicated with its inner cavity is fixedly connected to the outer wall of one of the air distribution cross pipes. The exhaust port of the air suspension aerator is fixedly connected with a communicated flexible hose. One port of the flexible hose is connected and communicated with the air inlet pipe.

[0009] As an optimized solution, the bubble guiding component includes two side baffles fixedly connected to opposite ends of the floating frame. A plurality of inclined guiding plates are vertically arranged between the two side baffles. The lengths of the plurality of guiding plates gradually decrease from top to bottom. Opposite ends of the guiding plates are respectively fixedly connected to the two side baffles.

[0010] As an optimized solution, a cleaning brush slidably arranged along the width direction of the floating frame is arranged between the two side baffles.

[0011] As an optimized solution, the floating component includes a positioning plate fixedly connected to the end of the floating frame. A fixing rod is fixedly connected to the end of the positioning plate. A plurality of floating cylinders are fixedly sleeved on the fixing rod.

[0012] As an optimized solution, sliding blocks are slidably arranged at opposite ends of the two side baffles facing each other. Opposite ends of the cleaning brush are respectively fixedly connected to the two sliding blocks.

[0013] As an optimized solution, fixing blocks are fixedly connected to opposite inner walls of the floating frame. A fixing plate is horizontally and fixedly arranged inside the floating frame. Two single-threaded lead screws are rotatably arranged at one end of the fixing plate. One ends of the two single-threaded lead screws respectively pass through the two sliding blocks and are rotatably connected to the two fixing blocks respectively. The single-threaded lead screws are in threaded connection with the sliding blocks.

[0014] As an optimized solution, two driving motors are fixedly arranged at the other end of the fixing plate.

[0027] As Figures 1 to 3 shown, an aeration device applicable to outdoor pond aquaculture includes a floating frame 8. Floating assemblies 4 are provided at both opposite ends of the floating frame 8. An exhaust mechanism 9 is provided at the inner bottom of the floating frame 8. A bubble guiding assembly 6 is provided at a position above the exhaust mechanism 9 inside the floating frame 8;

[0028] The exhaust mechanism 9 includes two air distribution cross pipes 13 arranged in parallel along the width direction of the floating frame 8. Both air distribution cross pipes 13 are fixedly connected to the floating frame 8. Two ports of one air distribution cross pipe 13 are respectively connected to two ports of the other air distribution cross pipe 13 through connecting pipes 20. A plurality of horizontally arranged nano aeration pipes 21 are arranged in parallel between the two air distribution cross pipes 13 along the length direction of the floating frame 8.

An air supply assembly 10 connected to one of the air distribution cross pipes 13 is provided outside the floating frame 8;

[0029] The floating component 4 enables the floating frame 8 to float in the water body of the outer pond; select a suitable aeration position and restrict the floating frame 8 at this aeration position through a suitable fixing method. With the cooperation of the connecting pipe 20, the air supply component 10 can continuously supply air into the two air distribution cross pipes 13. The air in the air distribution cross pipes 13 enters the nano-aeration pipes 21 and is discharged towards the bubble guiding component 6; the air discharged from the nano-aeration pipes 21 moves upward and drives the water body to flow upward together to form an oxygen-rich water flow.

The opposite ends of the guiding plates 23 are fixedly connected to the two side baffles 11 correspondingly.

[0033] The air discharged from the nano-aeration pipes 21 moves upward and enters the area between the plurality of guiding plates 23. During the upward movement of the air, it drives the water body to flow upward together to form an oxygen-rich water flow. The oxygen-rich water flow flows towards one side of the floating frame 8 under the guidance of the guiding plates 23 and forms an oxygen-rich zone, thereby aerating the water body and also playing the role of activating the water.

The cleaning brush 14 is located between the guiding plates 23 and the nano-aeration pipes 21 and is in frictional contact with the outer wall of the nano-aeration pipes 21.

[0035] During the sliding process of the cleaning brush 14, it can clean the impurities adhered to the outer wall of the nano-aeration pipes 21 to prevent the exhaust ports of the nano-aeration pipes 21 from being blocked.

[0038] Fixed blocks 22 are fixedly connected to the opposite inner walls of the floating frame 8. A fixing plate 12 is horizontally and fixedly arranged inside the floating frame 8. Two single-threaded lead screws 18 are rotatably arranged at one end of the fixing plate 12.

The single-threaded lead screws 18 are in threaded connection with the sliding blocks 19.

[0039] The opposite side walls of the fixing plate 12 are fixedly connected to the opposite inner walls of the floating frame 8 correspondingly.

[0040] Two driving motors 16 are fixedly arranged at the other end of the fixing plate 12. The output ends of the two driving motors 16 respectively pass through the fixing plate 12 and are fixedly connected to the two single-threaded lead screws 18 correspondingly. Waterproof shells 17 are fixedly sleeved on the driving motors 16.

[0041] A support plate 24 fixedly connected to the two positioning plates 5 is arranged above the floating frame 8. A solar photovoltaic power generation system 27 for supplying power to the driving motors 16 is arranged at the top of the support plate 24.

[0042] The solar photovoltaic power generation system 27 includes a support bracket 26 fixedly connected to the top of the support plate 24 and a storage battery 28. A solar panel 25 is fixedly arranged on the support bracket 26. The solar panel 25 is electrically connected to the storage battery 28. The storage battery 28 is also electrically connected to the two driving motors 16.

[0043] The working principle of this device is as follows:

[0044] When oxygenating the water body in the outer pond, the floating frame 8 floating in the water body is moved to a suitable oxygenation position, and the floating frame 8 is restricted at this oxygenation position by a suitable fixing method. The air suspension aerator 1 can compress and transport external air. With the cooperation of the connecting pipe 20, the compressed air sequentially enters the two air distribution cross pipes 13 through the connecting hose 2 and the air inlet pipe 15. The air in the two air distribution cross pipes 13 enters into a number of nano-aeration pipes 21 and is discharged into the water body. The air discharged from the nano-aeration pipes 21 moves upward and enters the area between a number of guide plates 23. The water body is driven to flow upward together during the upward movement of the air to form an oxygen-rich water flow. The oxygen-rich water flow flows to one side of the floating frame 8 under the guidance of the guide plates 23 and forms an oxygen-rich zone, thereby oxygenating the water body. It realizes bottom oxygenation of the outer pond without laying oxygenation pipelines, improves the oxygenation effect on the outer pond, increases the dissolved oxygen content of the aquaculture water body, improves the aquaculture density of the outer pond, reduces the aquaculture risk, and can also play the role of making the water live at the same time;

[0045] When impurities adhere to the outer wall of the nano-aeration pipe 21, the two drive motors 16 drive the two single-tooth lead screws 18 to rotate respectively, and then drive the two sliders 19 to slide horizontally, thereby driving the cleaning brush 14 to move horizontally. During the horizontal movement of the cleaning brush 14, the impurities adhering to the outer wall of the nano-aeration pipe 21 can be cleaned to prevent the impurities from blocking the exhaust port of the nano-aeration pipe 21 and affecting the oxygenation effect on the outer pond.

[0046] The storage battery 28 can store the electric energy generated by the solar panel 25, and then provide the required electric energy for the two drive motors 16. Moreover, using the air suspension aerator 1 for oxygenation is more efficient, energy-saving and environmentally friendly, improving the practicability of the device.
