Description

Technical Field

[0001] The invention relates to the technical field of biological culture barrels, in particular to an aquatic biological culture barrel used in a specific gas environment. Background Art

[0002] Scientific research shows that the special characteristics of the extreme deep-sea environment can be used to colonize, cultivate, and enrich microorganisms with special functions. By deciphering the physiological and biochemical characteristics of extreme microorganisms and the reasons for their generation, it can provide new directions for the development of special genes and products, and for the development of industry, agriculture, environment, energy, and human health. Unique biological communities live in the deep sea, of which shellfish are one of the main groups. Research on the growth characteristics of shellfish can provide a scientific basis for the protection of deep-sea biological resources. However, due to the complexity of the deep-sea environment, researchers cannot go down to the seabed to conduct long-term research on such organisms. Therefore, they need to use aquatic biological culture barrels, which create a specific gas environment by connecting to an external gas source and adjusting the content of the gas source entering the barrel space. Then, aquatic organisms are cultured and studied in this specific gas environment. During the culture process, detection probes need to be placed inside the barrel space to monitor water quality or measure the composition of the culture fluid.

[0003] In the prior art, for the combination between the detection probe and the barrel body, most of the time the detection probe is directly inserted into the slot opened on the outer surface of the barrel body. However, in actual use, since the outer surface of the detection probe and the inner wall of the slot on the barrel body are both hard structures, a very small gap will still be generated after the two are combined with each other. This indicates that the sealing between the two is poor, causing the gas and culture medium inside the barrel body space to flow out through the gap, and then causing the data obtained in the final monitoring process to be biased.

[0004] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art known to those skilled in the art.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, when the culture barrel needs to be connected to a detection probe to monitor water quality or measure the composition of the culture liquid, the interface plug can be pulled out, and then the detection probe can be inserted into the interior of the probe interface.

[0032] See also Figures 1-8 , an embodiment provided by the present invention:

[0033] A barrel for cultivating aquatic organisms in a specific gas environment comprises a barrel body 1, a barrel cover assembly 2 is fixedly mounted on the top of the barrel body 1, an air inlet 3 is also provided on the top of the barrel body 1, an air pipe 4 is installed through the top of the air inlet 3, an air inlet valve 5 is mounted on the end of the air pipe 4 away from the barrel body 1 through a flange, an air stone 6 is connected to the tail end of the air pipe 4, and the air stone 6 is located inside the barrel body 1;

[0034] The top of the barrel body 1 is also provided with an air outlet 7, the top of the air outlet 7 is penetrated by an air guide pipe 8, and the tail end of the air guide pipe 8 extends into the interior of the barrel body 1, and the other end of the air guide pipe 8 is installed with an air outlet valve 9 through a flange;

[0035] A probe interface 10 is fitted on the front of the barrel body 1, and an interface plug 11 is inserted into the inner wall of the probe interface 10. The interface plug 11 is a cylindrical structure, and its outer diameter matches the inner diameter of the probe interface 10. The probe interface 10 consists of a locking nut 12, a sealing gasket 13, a probe body 14, a rubber bushing 15 and a pressing cap 16. The probe body 14 extends through the outer wall of the barrel body 1 into its interior. The probe body 14 and the barrel body 1 are fixed and sealed by the sealing gasket 13 and the locking nut 12. A conical through hole is provided on the outside of the probe body 14, and a conical surface is provided on the outside of the rubber bushing 15. The conical surface of the rubber bushing 15 matches the inner wall of the through hole of the probe body 14. The inside of the rubber bushing 15 is provided with an inner hole. The outer surface of the interface plug 11 fits the inner wall of the through groove provided with the rubber bushing 15, and the inner wall of the pressing cap 16 is threadedly connected to the outer surface of the probe body 14.

[0036] The barrel body 1 has a large storage space, which is filled with a culture liquid for aquatic organisms. A large opening is provided on the top of the barrel body 1, and the barrel cover assembly 2 covers the top of the opening, which facilitates the placement and operation of experimental objects and plays a role in isolating from the outside world.

[0037] An external gas source is connected through the air inlet valve 5, and then the air supply device of the external gas source is started. When the air inlet valve 5 is opened, the external gas source enters the culture liquid through the air pipe 4 and the air stone 6. The air stone 6 can refine the gas into tiny bubbles, so that the gas and the culture liquid are fully integrated. The setting of the air outlet 7 and the air guide pipe 8 facilitates the discharge of excess gas inside the barrel 1 along the air guide pipe 8. The opening and closing of the air outlet valve 9 controls the dredging and blocking of the inside of the air guide pipe 8.

[0038] The probe interface 10 and the barrel body 1 are in a fixed and interlocking combination, and the interface plug 11 can be interlocked inside the probe interface 10 to play a sealing role. When the culture barrel needs to connect a detection probe to monitor water quality or measure the composition of the culture liquid, the interface plug 11 can be pulled out, and then the detection probe can be inserted into the interior of the probe interface 10. The probe interface 10 with a special structure facilitates seamless connection with the detection probe, and has good sealing performance, which is not easy to leak culture liquid and gas. When the pressing cap 16 is tightened, the rubber bushing 15 will be squeezed into the tapered through hole of the probe body 14, and the inner hole of the rubber bushing 15 will be squeezed and tapered at the same time. The interface plug 11 or the detection probe inserted into the probe interface 10 after the interface plug 11 is pulled out is tightly held, thereby achieving a sealing effect.

[0039] The culture barrel has a simple structure and low cost, and the large opening design facilitates the placement and operation of experimental objects. The special probe interface 10 facilitates seamless docking with the probe, has good sealing, and does not leak culture fluid and gas, solving the problems of existing culture devices that are bulky, expensive, and prone to leakage.

[0040] The top of the barrel cover assembly 2 is provided with two groups of circular grooves 17 arranged front and back, and the inner walls of the two groups of circular grooves 17 are movably connected with threaded cylinders 18. The top of the barrel cover assembly 2 is movably installed with two groups of locking pins 19 arranged front and back, and the outer surfaces of the two groups of locking pins 19 are respectively threadedly connected to the inner walls of the two groups of threaded cylinders 18. The bottoms of the two groups of threaded cylinders 18 are fixedly connected with the first airbag 20, and the bottoms of the first airbag 20 are fixedly connected with the second airbag 21, and the second airbag 21 is communicated with the first airbag 20. The second airbag 21 Inside the space of the barrel body 1, the top of the first airbag 20 is fixedly connected to the air intake assembly 22, and the top of the air intake assembly 22 is movably extended to the top of the barrel cover assembly 2. The air intake assembly 22 consists of a vertical tube 23, a rubber hose 24, a connecting sleeve 25 and a cap 26. The vertical tube 23 is fixedly connected to the top of the first airbag 20, the rubber hose 24 is fixedly connected to the top of the vertical tube 23, the connecting sleeve 25 is fixedly connected to the top of the rubber hose 24, and the cap 26 is threadedly sleeved on the outer surface of the connecting sleeve 25.

[0041] The threaded barrel 18 and the barrel cover assembly 2 are in a non-fixed combination. When no air is injected into the first airbag 20 and the second airbag 21, the two are placed inside the space of the barrel cover assembly 2, and then the two groups of threaded barrels 18 are passed through the inside of the two groups of circular grooves 17 from bottom to top, and then the locking pins 19 are inserted from the top of the circular grooves 17 into the inside of the threaded barrel 18, which plays the role of fixing the first airbag 20 on the top wall of the barrel cover assembly 2, and at this time the top of the air intake assembly 2 also passes upward from the inside of the space of the barrel cover assembly 2. When the internal components of the barrel cover assembly 2 are combined and sealed with each other, the airbag sealing structure composed of the first airbag 20 and the second airbag 21 extends into the space inside the barrel body 1, and then the cap 26 is unscrewed, and an external air pumping device is connected through the connecting sleeve 25, and then the air pumping device is started, and air is sent into the space inside the airbag sealing mechanism, so that it gradually expands and takes shape. The specific structure after forming is as follows. Figure 5 As shown, at this time, the outer surface of the first airbag 20 is tightly fitted with the inner wall of the bucket cover assembly 2. Similarly, the top of the second airbag 21 is tightly fitted with the top wall of the edge of a group of large openings opened in the bucket body 1, so as to further improve the sealing performance of the bucket cover assembly 2 when it is closed.

[0042] Compared with the traditional form of embedding a rubber gasket on the top wall of the barrel cover assembly 2, if the rubber gasket falls from the barrel cover assembly 2 and is not discovered in time, the sealing performance of the barrel cover assembly 2 will be reduced, and the culture medium and gas will be easily leaked.

[0043] An integrated plate 27 is fixedly installed on the outer wall of one side of the barrel body 1. A slot 28 is opened on the side of the integrated plate 27 away from the barrel body 1. The bottom of the integrated plate 27 is rotatably connected to a T-shaped turntable 29. The top of the T-shaped turntable 29 is fixedly connected to a threaded rod 30, and the top of the threaded rod 30 passes through the inside of the slot 28. A T-shaped limiting column 31 is rotatably installed on the top of the integrated plate 27, and the bottom of the T-shaped limiting column 31 is fixedly connected to the top of the threaded rod 30. The outer surface of the threaded rod 30 is threadedly connected to a slide 32. A U-shaped plate 33 is fixedly installed on one side of the slide 32, and the concave portion of the U-shaped plate 33 is fixedly connected to the bottom of the slide 32. The inner wall of the recess is slidably connected to the outer surface of the integrated board 27. Circular grooves are provided on the front and back of the integrated board 27. The front and back of the integrated board 27 are rotatably connected to the first handle 34 through two groups of circular grooves. The front and back of the integrated board 27 are provided with chimeric slide grooves 35. The front and rear walls of the recess of the U-shaped plate 33 are fixedly installed with snap blocks 36, and the outer surfaces of the two groups of snap blocks 36 are respectively slidably connected to the inner walls of the two groups of chimeric slide grooves 35. The outer wall of the other side of the barrel body 1 is fixedly installed with an assembly block 37, and the inner wall of the assembly block 37 is rotatably connected to the second handle 38.

[0044] By applying a rotational force in a set direction to the T-shaped turntable 29, the threaded rod 30 can be driven to rotate together. At this time, the slide 32 threadedly sleeved on the outer surface of the threaded rod 30 can move up or down along the outer surface of the threaded rod 30 accordingly, thereby driving the U-shaped plate 33 and the first handle 34 to adjust their height positions up and down. At the same time, the two sets of engaging blocks 36 slide up and down along the inner walls of the two sets of engaging grooves 35.

[0045] Since the weight and volume of this culture barrel are relatively large, it generally requires two workers to cooperate in carrying it. The height and arm length of the workers may differ greatly. When two groups of workers with different heights carry this culture barrel, two situations may occur. First, the shorter person lets his arms hang down naturally when lifting the culture barrel, while the taller person needs to bend his back to lift the culture barrel, so that his palms are at the same height as the palms of the other group of workers. Then the two people lift the culture barrel together. After lifting for a long time, the taller person's spine will be more sore. Second, the taller person lets his arms hang down naturally when lifting the culture barrel, while the shorter person needs to bend his wrist joints. At this time, he applies more force, and his arms are more likely to be sore after lifting for a long time.

[0046] In this culture barrel, the height position of the second handle 38 installed on one side of the outer wall through the assembly block 37 remains unchanged, and the height position of the first handle 34 installed on the other side of the outer wall is adjustable, which can better adapt to two groups of people of different heights to move the culture barrel.

[0047] A drain pipe 39 is fixedly connected to the outer surface of the barrel body 1 , and a drain valve 40 is installed at one end of the drain pipe 39 .

[0048] The setting of the drain pipe 39 facilitates the discharge of the culture solution and bottom sediment inside the space of the barrel body 1. At the same time, the opening and closing of the drain valve 40 controls whether the drain pipe 39 is in a clear state.

[0049] The barrel cover assembly 2 consists of a barrel cover tube 41, a top cover 42 and a sealing cylinder 43. The barrel cover tube 41 is fixedly installed on the top of the barrel body 1, the top cover 42 is movably connected to the top of the barrel cover tube 41, and the sealing cylinder 43 is fixedly installed on the bottom of the top cover 42. The inner wall of the sealing cylinder 43 is connected to the outer surface of the barrel cover tube 41 by a threaded connection.

[0050] The sealing cylinder 43 and the barrel cover tube 41 are assembled by threaded engagement, and the two are detachable. When a rotational force is applied to the horizontal plate on the top of the top cover 42, the sealing cylinder 43 can be driven to rotate along the outer surface of the barrel cover tube 41, thereby causing the two to gradually separate or combine.

[0051] Working principle: The culture liquid of aquatic organisms is loaded through the barrel body 1, and the external air source is connected through the air inlet valve 5, and then the air supply device of the external air source is started. After that, when the air inlet valve 5 is opened, the external air source enters the culture liquid through the air pipe 4 and the air stone 6, and the air stone 6 can refine the gas into tiny bubbles, so that the gas and the culture liquid are fully integrated. When this culture barrel is not being monitored, the interface plug 11 is inserted into the inside of the probe interface 10. Conversely, when this culture barrel needs to be connected to a detection probe to monitor water quality or measure the composition of the culture liquid, the interface plug 11 can be pulled out, and then the detection probe can be inserted into the inside of the probe interface 10. After that, when the pressing cap 16 is tightened, the rubber bushing 15 will It will be squeezed into the tapered through hole of the probe body 14, and the inner hole of the rubber bushing 15 will be squeezed and become thinner at the same time, so that the interface plug 11 or the detection probe inserted into the probe interface 10 after the interface plug 11 is pulled out will be tightly held, thereby achieving a sealing effect, and its sealing performance is good, and it is not easy to leak culture fluid and gas. At the same time, before the barrel cover assembly 2 is sealed, the airbag sealing structure composed of the first airbag 20 and the second airbag 21 is combined with the barrel cover assembly 2. After that, after the barrel cover assembly 2 is sealed, an air pumping device is connected to the outside through the connecting sleeve 25, and then the air pumping device is started to send air into the space inside the airbag sealing mechanism, so that it gradually expands and takes shape. The specific structure after forming is as follows Figure 5 As shown, at this time, the outer surface of the first airbag 20 is tightly fitted with the inner wall of the barrel cover assembly 2. Similarly, the top of the second airbag 21 is tightly fitted with the top wall of the edge of a group of large openings opened in the barrel body 1, so as to further improve the sealing performance of the barrel cover assembly 2 when it is closed, and by rotating the T-shaped turntable 29 to drive the threaded rod 30 to rotate, the height position of the first handle 34 can be adjusted by the slide 32 and the U-shaped plate 33, so that the height position of the second handle 38 and the adjusted first handle 34 can be adapted to the height of the two groups of staff who carry the culture barrel.
