Description

Technical Field

[0001] This application relates to the field of microbial culture technology, and in particular to a large culture vessel for photosynthetic microorganisms. Background Technology

[0002] Photosynthetic bacteria are a general term for a class of prokaryotic microorganisms that use light as energy, CO2 or organic matter as carbon source, and hydrogen sulfide as hydrogen donor, and carry out autotrophic or heterotrophic activities. They are widely distributed in soil, paddy fields, swamps, lakes and rivers and seas in nature. They have a variety of physiological and biochemical functions such as nitrogen fixation, hydrogen production, carbon fixation and desulfurization, and play a very important role in the material cycle in nature.

[0003] According to literature review, an existing patent (publication number: CN221759846U) discloses a photosynthetic microorganism culture device, including a transparent box, a rotating mechanism is provided inside the transparent box, a fixing mechanism is provided on the rotating mechanism, and a moving mechanism is provided on the transparent box.

[0004] Although the existing technology mentioned above uses a motor to drive a rotating shaft, which in turn drives a support plate and a mounting plate to rotate, thereby causing the test tubes to rotate at a uniform speed, increasing the uniformity of light exposure and improving the culture efficiency of microorganisms, in actual use, this existing technology can only culture one set of photosynthetic microorganism sample test tubes. It is inconvenient when there are many photosynthetic microorganism samples that need to be cultured, and the limited capacity of the test tubes results in low culture efficiency and poor practicality. In view of this, we propose a large culture vessel for photosynthetic microorganisms to solve the above problems. Utility Model Content

[0013] By adopting the above technical solution, the clamping of individual test tubes can be removed, making it easier for staff to handle individual test tubes and improving the overall flexibility of the device.

[0031] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0032] This application discloses a large culture dish for photosynthetic microorganisms.

[0033] Reference Figures 1-6A large culture vessel for photosynthetic microorganisms includes a transparent box 1 that allows for easy exposure to sunlight. A fixing plate 2, providing support and fixation, is fixedly connected inside the transparent box 1. A first cavity 201 is formed inside the fixing plate 2. Six support plates 3 are rotatably mounted inside the fixing plate 2. Six placement grooves 301 for placing test tubes are formed on the upper surface of the six support plates 3. Support rods 4, providing connection and support, are fixedly connected to the upper surface of the support rods 4. Placement plates 5 are fixedly connected to the upper end of the support rods 4. Six placement slots 501, also for placing test tubes, are formed inside the placement plates 5. A motor 6 is fixedly connected to the bottom wall of the transparent box 1. Fixing rods 7, providing connection, are fixedly connected to the lower surfaces of the two left-side support plates 3. The output shaft of the motor 6 is fixedly connected to the front fixing rods 7. The motor 6 is started via a microcomputer and controller, and the rotation of the output shaft of the motor 6 drives the front fixing rods 7 to rotate.

[0034] Both fixed rods 7 are fitted with synchronous pulleys 8, and synchronous belts 9 are meshed with the surfaces of the two synchronous pulleys 8. The synchronous rotation of the rear fixed rods 7 can be achieved through the transmission of the two synchronous pulleys 8 and the synchronous belts 9, thereby achieving the rotation of the two left support plates 3. The surface of the support plate 3 is fitted with gears 10 for transmission. The gears 10 are located inside the first cavity 201. The three gears 10 on the front and rear sides are meshed with each other. The rotation of the two left support plates 3 can drive the rotation of the two left gears 10. Finally, the meshing of the gears 10 achieves the synchronous rotation of the six support plates 3. The placement plate 5 has a second cavity 11 inside, and a fixing component for clamping the test tube is set inside the second cavity 11.

[0035] Among them, the motor 6 is also equipped with a power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail.

[0036] The fixing assembly includes six rotating shafts 12 for support, all of which are rotatably connected inside the second cavity 11. Each rotating shaft 12 is equipped with a first clamping ring 13 and a second clamping ring 1301 for holding the test tube. The first clamping ring 13 is fixedly sleeved on the surface of the rotating shaft 12, and the second clamping ring 1301 is rotatably sleeved on the surface of the rotating shaft 12. A second torsion spring 27 is fixedly connected between the first clamping ring 13 and the second clamping ring 1301, and the second torsion spring 27 is movably sleeved on the outside of the rotating shaft 12. The surfaces of the first clamping ring 13 and the second clamping ring 1301 are both fixedly connected to a connecting plate 14. The movement of the connecting plate 14 causes the first clamping ring 13, the second clamping ring 1301, and the connecting plate 14 to open to both sides. At this time, the first clamping ring 13 will rotate around the rotating shaft 12, and the second clamping ring 1301 will drive the rotating shaft 12 to rotate together, thereby achieving that the first clamping ring 13 and the second clamping ring 1301 set inside the placement plate 5 are both in an open state.

[0037] In order to improve the stability of the first clamping ring 13 and the second clamping ring 1301 in clamping the test tube, rubber pads can be provided on the inner walls of the first clamping ring 13 and the second clamping ring 1301. The rubber pads contact the test tube, thereby increasing the friction between them and the test tube. At the same time, it can also avoid damage to the test tube caused by hard contact, thus improving both safety and clamping stability.

[0038] The top wall of the second cavity 11 is provided with a sliding groove 15. A sliding plate 16 is slidably connected inside the sliding groove 15. Six first trapezoidal blocks 17 for driving the movement of the connecting plate 14 are fixedly connected to the lower surface of the sliding plate 16 through a shaft. The sliding of the sliding plate 16 can drive the first trapezoidal blocks 17 to move downward. The first trapezoidal blocks 17 are located between two adjacent connecting plates 14. Because the first trapezoidal blocks 17 are located between two connecting plates 14 and their inclined surfaces are in contact with the connecting plates 14, the connecting plates 14 will be pushed open to both sides during the movement of the first trapezoidal blocks 17.

[0039] A square rod 18 is fixedly connected to the upper surface of the sliding plate 16. The square rod 18 slides through the interior of the placement plate 5. By sliding downward through the square rod 18, the sliding plate 16 is driven to slide inside the sliding groove 15. The upper end of the square rod 18 is rotatably connected to a threaded rod 19 that serves as a drive. The upper end of the threaded rod 19 is threaded through the interior of the placement plate 5. When the operator rotates the threaded rod 19, because the threaded rod 19 is threaded inside the placement plate 5, the threaded rod 19 will be displaced when it rotates. Since the threaded rod 19 and the square rod 18 are rotatably connected, the rotation of the threaded rod 19 will drive the square rod 18 to slide downward.

[0040] The placement plate 5 has six vertical rods 21 that serve as connectors. The lower ends of the six vertical rods 21 extend into the interior of the second cavity 11. The lower ends of the six vertical rods 21 are fixedly connected to a second trapezoidal block 20, which is also used to drive the movement of the connecting plate 14. The second trapezoidal block 20 is also located between two adjacent connecting plates 14. When a single test tube needs to be removed, the vertical rods 21 are pressed down. The movement of the vertical rods 21 will drive the movement of the second trapezoidal block 20. Then, the inclined surface of the second trapezoidal block 20 will contact the connecting plate 14, thereby pushing the connecting plate 14 open. The upper ends of the six vertical rods 21 extend out of the interior of the placement plate 5. The upper ends of the vertical rods 21 are provided with compression springs 22 to facilitate the reset of the vertical rods 21. The upper ends of the compression springs 22 are fixedly connected to the vertical rods 21, and the lower ends of the compression springs 22 are fixedly connected to the upper surface of the placement plate 5.

[0041] The inclined surfaces of the first trapezoidal block 17 and the second trapezoidal block 20 are in contact with the surface of the connecting plate 14.

[0042] The placement plate 5 has six third cavities 23 inside. The upper ends of the six rotating shafts 12 are respectively rotated and penetrate into the six third cavities 23. The upper ends of the rotating shafts 12 are fixedly connected to the circular plates 24. The circular plates 24 and the bottom walls of the third cavities 23 are fixedly connected to the first torsion springs 25 to facilitate the reset of the rotating shafts 12. The first torsion springs 25 are movably sleeved on the outside of the rotating shafts 12. By reversing the threaded rod 19, the square rod 18, the sliding plate 16 and the first trapezoidal block 17 are driven to move upward. At this time, the first clamping ring 13 and the second clamping ring 1301 are reset by the elastic force of the first torsion springs 25 and the second torsion springs 27, thereby realizing the clamping of multiple test tubes.

[0043] The inner wall of the transparent box 1 is provided with an illumination tube 26 for illuminating the test tube. The illumination tube 26 is an existing structure. For details, please refer to the prior art with publication number CN221759846U. Therefore, it will not be described in detail in this article.

[0044] The implementation principle of a large culture dish for photosynthetic microorganisms in this application embodiment is as follows: When the operator rotates the threaded rod 19, because the threaded rod 19 is threaded inside the placement plate 5, the threaded rod 19 will displace during rotation. Since the threaded rod 19 and the square rod 18 are rotatably connected, the rotation of the threaded rod 19 will cause the square rod 18 to slide downwards, thereby causing the sliding plate 16 to slide inside the sliding groove 15. The sliding of the sliding plate 16 will cause the first trapezoidal block 17 to move downwards. Furthermore, because the first trapezoidal block 17 is located between the two connecting plates 14, its inclined surface is connected to the connecting plates 14. Therefore, during the movement of the first trapezoidal block 17, the connecting plate 14 will be pushed open to both sides. In turn, the movement of the connecting plate 14 will cause the first clamping ring 13 and the second clamping ring 1301 and the end of the connecting plate 14 fixed to them to open to both sides. At this time, the first clamping ring 13 will rotate around the rotating shaft 12, and the second clamping ring 1301 will drive the rotating shaft 12 to rotate together. Thus, the first clamping ring 13 and the second clamping ring 1301 set inside the placement plate 5 are both in the open state. Subsequently, the test tube to be cultured can be placed inside the placement channel 501 and the placement groove 301.

[0045] Furthermore, when the first clamping ring 13 and the second clamping ring 1301 rotate, both the first torsion spring 25 and the second torsion spring 27 will deform.

[0046] After the test tubes are placed, the reverse threaded rod 19 drives the square rod 18, the sliding plate 16 and the first trapezoidal block 17 to move upward. At this time, the first clamping ring 13 and the second clamping ring 1301 will be reset by the elastic force of the first torsion spring 25 and the second torsion spring 27, thereby achieving the clamping of multiple test tubes.

[0047] Subsequently, the photosynthetic microorganism sample tubes can be illuminated by turning on the lighting tube 26. At the same time, the motor 6 can be started by the microcomputer and controller. The rotation of the output shaft of the motor 6 will drive the front fixing rod 7 to rotate. At this time, the rear fixing rod 7 can be rotated synchronously through the transmission of the two synchronous pulleys 8 and the synchronous belt 9, which in turn will cause the two support plates 3 on the left to rotate. The rotation of the two support plates 3 on the left will drive the rotation of the two gears 10 on the left. Finally, the meshing of the gears 10 will achieve the synchronous rotation of all six support plates 3, thereby causing the test tubes to rotate at a uniform speed and increasing the uniformity of light exposure.

[0048] When a single test tube needs to be removed, the vertical rod 21 is pressed down. The movement of the vertical rod 21 will drive the movement of the second trapezoidal block 20. Then, the inclined surface of the second trapezoidal block 20 will contact the connecting plate 14, thereby pushing the connecting plate 14 open and finally removing the clamp on the single test tube. The compression spring 22 will also deform.

[0049] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
