Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture equipment, in particular to an oxygenation device for a Macrobrachium rosenbergii greenhouse pond. Background Art

[0002] Macrobrachium rosenbergii, also known as the Malay prawn, giant long-arm prawn, and freshwater prawn, is an arthropod of the family Macrobrachium. Currently, artificial aquaculture is mostly carried out in greenhouses, with ponds generally maintained at a depth of 1.5 meters. Greenhouse shrimp farming utilizes the greenhouse's thermal insulation properties to isolate the shrimp's growth from the external environment, providing an optimal growth environment and increasing shrimp farming profits. During Macrobrachium rosenbergii farming, it is necessary to maintain a dissolved oxygen level greater than 2.8 mg / L in the pond water. Below this value, the prawns will float. During the growing season, the aerator should be operated at least twice daily for at least two hours each time.

[0003] In the prior art, aeration pipes are typically laid at the bottom of the pond, fitted with air stones. These pipes are then connected to an air pump, which injects air into the pipes. The air then overflows from the air stones into the water, forming small bubbles that increase the dissolved oxygen content and water flow. However, in artificially farmed shrimp ponds, the shrimp population is large, and the combination of shrimp excrement and microbial growth can easily clog the air stones. Furthermore, the aeration pipes, installed at the bottom of the pond, can become buried in sludge after prolonged use, similarly reducing the oxygenation effect. Utility Model Content

[0004] In order to make up for the above deficiencies, the utility model provides an oxygenation device for a Macrobrachium rosenbergii greenhouse pond.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1:

[0029] See also Figure 1-4 The present invention describes the above technical solution in detail through the following embodiments:

[0030] An oxygenation device for a Macrobrachium rosenbergii greenhouse pond, comprising:

[0031] The oxygenation device 1 includes an air source 11 , which is connected to an oxygenation pipe 15 through a pipeline. The oxygenation pipe 15 is connected to a plurality of bubble stones 17 through an air outlet pipe 16 . The air source 11 is used to transport air to the oxygenation pipe 15 .

[0032] The oxygenation pipe 15 is laid at the bottom of the shrimp pond 4.

[0033] The air source 11 can be a well-known air compression device or an air pump.

[0034] The air stone 17 is clamped with the air outlet pipe 16. The air stone 17 is made of porous quartz material and has many tiny pores.

[0035] The pipeline includes a delivery pipe 12 , the diameter of the delivery pipe 12 is larger than the oxygenation pipe 15 , and a control valve is installed between the delivery pipe 12 and the oxygenation pipe 15 .

[0036] The delivery pipe 12 can be a hard pipe such as a PVC pipe.

[0037] The control valve includes a control valve 13 and a one-way valve 14. The control valve 13 is used to control the connection between the aeration pipe 15 and the delivery pipe 12. The one-way valve 14 only allows the air in the delivery pipe 12 to enter the aeration pipe 15, and does not allow the air in the aeration pipe 15 to return to the delivery pipe 12.

[0038] The support assembly 2 includes a support frame and a floating assembly. The support frame is located on both sides of the outlet pipe 16 and is used to support the oxygenation pipe 15. The floating assembly is located on the top of the support frame and is connected to the oxygenation pipe 15. It can float when the oxygenation pipe 15 is ventilated.

[0039] The support frame includes a sliding sleeve 21, which is fixedly connected to the oxygenation pipe 15. Two support rods 22 are symmetrically provided at the bottom of the sliding sleeve 21, and the angle between the two support rods 22 is 120 degrees.

[0040] The sliding sleeve 21 and the support rod 22 are integrally formed of plastic material. The sliding sleeve 21 and the oxygenation pipe 15 are fixed by adhesive.

[0041] The support rod 22 can raise the height of the oxygenation tube 15 .

[0042] The floating assembly includes a vent pipe 23 , in which a buoy 24 is slidably installed. An elastic member 25 is provided between the outer wall of the buoy 24 and the inner wall of the vent pipe 23 , and the top of the buoy 24 can extend out of the top of the vent pipe 23 .

[0043] The vent pipe 23 and the sliding sleeve 21 are made of the same material and are integrally formed.

[0044] The elastic member 25 can be a plastic-coated coil spring. Under the elastic force of the elastic member 25, the buoy 24 is accommodated in the vent pipe 23.

[0045] An opening is provided at the bottom of the buoy 24 , and a through hole is provided on the oxygenation pipe 15 directly below the buoy 24 .

[0046] When air is introduced into the aeration tube 15, gas enters the float 24 from the through-hole below the float 24. As the air pressure increases, the float 24 overcomes the elastic force of the elastic member 25 and moves upward, thereby extending out of the top of the ventilation tube 23. When the air supply to the aeration tube 15 is stopped, the elastic force of the elastic member 25 drives the float 24 to slide downward, and the excess air in the aeration tube 15 is squeezed out through the bubble stone 17.

[0047] The protection component 3 includes a fixed part and a movable part. The movable part and the fixed part cooperate to wrap the bubble stone 17. The movable part is connected to the floating component and can move with the floating component.

[0048] The moving part includes a sealing cover 33 , which is slidably mounted on the outside of the air stone 17 , and the top of the sealing cover 33 is fixedly connected to the two buoys 24 via a connecting plate 34 .

[0049] The sealing cover 33 is a cylinder with an opening at the bottom. When the float 24 moves, the sealing cover 33 can be driven to move. Since the sealing cover 33 is open at the bottom, water cannot enter the sealing cover 33.

[0050] The fixing member includes a bottom plate 31 , which is snap-fitted to the head of the air outlet pipe 16 . A plurality of drainage holes 32 are formed through the bottom plate 31 , and the bottom plate 31 is slidably connected to a sealing cover 33 .

[0051] When the bottom plate 31 is combined with the sealing cover 33 , the drainage holes 32 can facilitate the discharge of gas when the air stone 17 is working, while preventing shrimp larvae from entering between the air stone 17 and the sealing cover 33 .

[0052] In this embodiment, when the operator uses the device, he controls the gas source 11 to work and opens the control valve 13 .

[0053] The air produced by the air source 11 enters the oxygenation tube 15 through the delivery pipe 12 and then escapes from the air bubble stone 17. The speed at which the air is discharged by the air bubble stone 17 should be less than the speed at which the air source 11 delivers the air.

[0054] At this time, the bottom plate 31 is combined with the sealing cover 33 , and the air released by the bubble stone 17 is discharged from the drainage hole 32 .

[0055] As air accumulates in the aeration tube 15 and the pressure increases, the float 24 overcomes the elastic force of the elastic member 25 and moves upward, extending out of the top of the vent tube 23. The movement of the float 24 drives the sealing cap 33 to move, thereby disengaging the air stone 17.

[0056] At this time, the air released by the bubble stone 17 contacts the water to form a large number of tiny bubbles, and part of the oxygen in the bubbles dissolves into the water, thereby increasing the dissolved oxygen content.

[0057] At the same time, the escaped bubbles can drive the water to roll.

[0058] After a period of oxygenation, the gas source 11 is stopped and the control valve 13 is closed. Due to the presence of the one-way valve 14, the air in the oxygenation pipe 15 can only escape from the bubble stone 17.

[0059] As the remaining air in the aeration tube 15 decreases and the air pressure drops, the elastic force of the elastic member 25 drives the float 24 to slide downward and squeezes the excess air in the aeration tube 15 out of the bubble stone 17 .

[0060] The downward sliding of the float 24 can drive the sealing cover 33 to move downward and re-engage with the bottom plate 31. During the downward movement of the sealing cover 33, gas will always escape from the air stone 17, ensuring that no water will enter the sealing cover 33, thereby ensuring that the area around the air stone 17 is dry, thereby reducing the growth of microorganisms on the surface of the air stone 17.

[0061] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
