Description

Technical Field

[0001] The utility model relates to the field of incubators, in particular to an incubator for marine biological experiment samples. Background Art

[0002] Marine life refers to various organisms in the ocean, including marine animals, marine plants, microorganisms and viruses. Marine microorganisms, as an important biologically active natural product, are the life form with the highest abundance and biomass in the ocean. Marine microorganisms play an important role in the circulation of key elements such as carbon, nitrogen and sulfur, and are an important member of the biogeochemical cycle. The marine microbial incubator is one of the indispensable devices for professional marine biological experiments.

[0003] After searching, Chinese patent announcement number: CN215877979 U discloses a shipborne marine biological experimental sample incubator, including a box body and a light-shielding cover connected to the upper end of the box body, and a plurality of pairs of vertical slots are opened on the inner wall of the box body. By inserting partitions into the vertical slots, a culture tank and an overflow buffer tank for placing experimental sample bottles are formed in the box body, and by inserting partitions into each vertical slot formed in the culture tank, the size of the culture tank can be adjusted to adapt to experimental sample bottles of different sizes. This patent can form a shading effect on the culture tank in the box by inserting the shading cover into the horizontal slot at the upper end of the box, which can better control the consistency of other conditions in the comparative experiment and ensure that the culture conditions in each culture box during the comparative experiment are a single variable as much as possible, thereby improving the accuracy of the experimental data. However, in the process of controlling the variable by blocking the light through the shading cover, since the shading baffle is designed as a long plate, when the shading baffle is inserted into the slot at the upper end of the box, the light is completely blocked by the shading baffle, resulting in that all microorganisms in culture cannot receive light, and the irradiation range of light cannot be controlled when other conditions remain unchanged. There is a lack of control experimental groups for observing microbial cultures under different lighting conditions in the same environment, which reduces the accuracy of the experiment. Therefore, a marine biological experimental sample incubator is proposed to solve the above problems. Utility Model Content

[0033] Working principle: When in use, the culture solution for culturing marine microorganisms is input into the interior of the housing 1 through the liquid inlet pipe 22, and then the power supply of the stepper motor 5 is started. The stepper motor 5 drives the rotating shaft 6 to rotate, and the rotation of the rotating shaft 6 drives the bracket 7 to rotate. The rotation of the bracket 7 drives the stirring blade 9 on the rotating rod 8 to revolve around the surface of the fixed column 12. While the stirring blade 9 revolves, the gear 1 10 also revolves around the gear 2 11, so that the gear 10 also rotates around its own central axis, thereby driving the stirring blade 9 to rotate around its own central axis, thereby stirring the culture solution inside the housing 1, improving the mixing uniformity of air and culture solution, allowing microorganisms to obtain the oxygen required for growth, and improving the cultivation efficiency of microorganisms. The stirring range of the stirring blade 9 is increased by rotating the stirring blade 9 while revolving, so that the culture solution at various positions inside the housing 1 can be mixed evenly, and at the same time, it can also prevent microorganisms from agglomerating and sinking to the bottom, resulting in a reduced ability of the microorganisms to absorb nutrients.

[0034] Turn on the power of the fill light 20, and then press the card block 16 downward so that the card block 16 overcomes the elastic force of the spring 17 and moves downward until the card block 16 is completely separated from the inside of the card slot 18. At this time, pull the moving rod 15 left and right to drive the light shielding plate 14 to move left and right, thereby adjusting the degree of shielding of the light shielding plate 14 from the fill light 20. When the card block 16 is adjusted to a suitable position, release the card block 16, so that the card block 16 is re-engaged in the inside of the card slot 18 under the elastic force of the spring 17, thereby completing the fixation of the light shielding plate 14, and then install the box cover 3 on the top of the box body 1 through the handle 4, so that a predetermined flux of light can be continuously provided to the inside of the box body 1, which is conducive to controlling the difference in the growth of different microorganisms when a single variable of light is changed while other conditions remain unchanged, thereby ensuring the accuracy of the experimental data.
